Service HotlineYueluo - a screw and nut disassembly tool for a narrow space, including a sleeve rod, a sleeve rod vertically arranged at one end of the sleeve rod, a connecting rod for fixedly connecting the sleeve rod and the sleeve rod, and a sleeve rod located at the end of the sleeve rod. The connecting rod in the axial through hole of the sleeve rod, the connecting rod located in the axial through hole of the sleeve rod, and the bearing for fixedly connecting the sleeve rod and the connecting rod and making the connecting rod rotate stably in the sleeve rod , and a sleeve head arranged at one end of the connecting rod, the connecting rod and the adjacent end of the connecting rod are provided with gears and the two gears are vertically meshed, so that when the external force drives the connecting rod to rotate, the force passes through The two gears and the connecting rod are transmitted to the sleeve head, thereby driving the screw or nut in the sleeve head to rotate;
The anti-rotation T-bolt includes a screw rod and a head. An anti-rotation protrusion is designed at the connection between the head and the screw. The cross-section of the anti-rotation protrusion is a square corner with the screw radius as the side length. One anti-rotation protruding shoot can be designed, or two can be designed. In order to ensure the uniform force of the bolt, two are designed.
Moisture-proof measures Iron screws are easy to rust in a humid environment. In order to prevent the screws from rusting, the screws need to be moisture-proof and moisture-proof. The moisture-proof and moisture-proof methods of screws are as follows: (1) Vibration machinery, try to use solvent-free paint. (2) It is best to use impregnating paints that do not contain oxidative components, such as epoxy-urethane (Epoxy-urethane)-based or unmodified epoxy-based (Epoxy-)-based impregnating paints. (3) When using melamine alkyd impregnating paint, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130 °C (such as 135 °C) and the curing time should be longer than 180min, and the process must be strictly implemented, especially In the hot and humid season, the drying (curing) time of the paint specified in the paint factory's samples is not necessarily sufficient from the perspective of rust prevention, and the motor has a specific inner shape. (4), use paint without volatile acid. (5) Choose paint with good hydrolysis resistance.
The utility model proposes an installation structure which adopts a T-shaped bolt to cooperate with a channel, which includes a bolt head, an installation channel, a nut and a washer. The upper end of the screw rod is provided with a screw head, the two side walls of the bolt head are respectively provided with an arc surface, the two ends of the bolt head are provided with protrusions, and the interior of the installation channel is provided with an inner cavity, There is an opening above the installation channel, the bolt head is installed in the inner cavity, the nut is installed on the screw, the nut is located above the installation channel, and the gasket is installed on the installation channel and the nut between.
Advantages of anti-loose washers 1. Ensure that the clamping force of the connection is still maintained under strong vibration, which is better than fasteners that rely on friction to come from the lock; 2. Prevent the loosening of bolts caused by vibration, which no longer occurs due to fasteners related problems caused by loosening; 3. No special installation work is required, and it is easy to install and disassemble; 4. The temperature changes will not make the connector loose; 5. Durable; 6. Reusable.
