Service HotlineThere is an anti-theft screw, which can prevent the use of any disassembly tool for disassembly, and effectively plays the role of anti-theft. Its structure is that the anti-theft screw is composed of two parts; the upper part is a hexagonal part, and the lower part is a threaded part; the hexagonal part and the threaded part are connected in rotation; The core shell is formed with the lock core; the lock core is rotatably connected with the lock core shell. The shell of the lock cylinder is fixedly connected with the hexagonal piece, and the starting structure is as follows: a pin hole is arranged on the hexagonal piece; The lower part of the hexagonal part is provided with a polygonal hole, which is connected with the polygonal hole on the threaded part; the lower part of the lock cylinder is a threaded rod; the threaded rod is located in the polygonal hole; The edge block moves up and down in the polygonal hole. When working, slowly twist the hexagonal piece from left to right and turn the key at the same time to achieve the alignment of the upper and lower polygonal holes.
Among them, the pneumatic riveting machine is more commonly used. The pneumatic riveting machine is also equipped with a clamp for assembling the rivet. The existing clamp usually uses two rotating clamps for fastening and assembly, but the rotation easily causes the two clamps to buckle. Misalignment, thus affecting the assembly of the rivet.
The types of rivets can be roughly divided into open type, closed type, double drum type and single drum type series. The following is a brief description of their respective models. Countersunk head blind rivets: For the riveting of riveting parts that require smooth and beautiful surfaces after riveting. Double-drum blind rivet: During riveting, the mandrel pulls the end of the rivet body into a double-drum shape, clamps the two structural parts to be riveted, and can reduce the pressure acting on the surface of the structural parts. Uses: Mainly used for riveting various thin structural parts in various vehicles, ships, construction, machinery, electronics and other industries. Blind rivet with large brim: Compared with ordinary blind rivets, the diameter of the aluminum cap of this rivet is significantly larger. When the rivet is riveted with the connector, it has a larger contact area and a stronger supporting surface, which can enhance the torque Strength, can withstand higher radial tension. Applicable industry: It is suitable for fastening soft and fragile surface materials and extra-large holes. The increased diameter of the brim has special protection applications for soft materials. Closed Blind Rivet: Designed to wrap around the mandrel head after riveting, ideal for many applications where waterproofing is required. With high shear force, anti-vibration, anti-high pressure.
The material of the second combination screw: It is decided to use the test machine to test the material of the combination screw wire, which is divided into iron and stainless steel. Iron wire is divided into 1010 wire and 1018 wire, 10B21 wire, etc., stainless steel is divided into stainless steel 201, stainless steel 304, stainless steel 316 and so on. The provisions of the national label of three combination screws: Generally, those who have experience in combination screws can be separated by using the inner eye. The difference between hexagon heads. Use a caliper to measure out the three-combination screw specifications. How big is it, how long is it, how thick is the head of the combination screw, how thick is the flat washer, and what is the outer diameter of the flat washer. How many hours is the salt spray of the combination screw measured with a salt spray machine. Use the environmental test machine to test whether the three-combination screw is environmentally friendly. Still not environmentally friendly.
For common screw belts, please refer to the Central Taiwan Announcement No. 327442 Screw Belts (2) on February 21, 1998. It includes a main body, and there are multiple grooves on the side of the main body, which are used for locking screw tools to drive the belt. A toggler; and a plurality of nail grooves are arranged on the nail belt so that the screw planting is arranged in an arrangement, and the nail grooves are all provided with through holes, and the through holes extend downward with a ring to form a support portion for the screws; and the It is surrounded and provided with a plurality of cutting grooves, which is beneficial for the screw to be rotated through the nail groove; and it is characterized in that the nail groove is located on the inner wall surface of the surrounding and is provided with a plurality of lobes, and these lobes are implanted in the screw. In the nail groove, the leaflet supports the screw, so that the screws with different outer diameters are fully supported and positioned by the leaflet; and/or the upper part of the leaflet is inclined or curved, so that a depression is formed above the ring to support the screw The arc surface or tapered surface of the neck can make the screw more stable to be supported.
