Abstract
The utility model provides an electric power engineering car hatch door bolt structure, includes bolt extension board, round pin handle, round pin connecting rod, round pin head, its characterized in that, round pin handle pass the locating hole on the bolt extension board with round pin connecting rod one end threaded connection, the other end of round pin connecting rod is opened there is the external screw thread, has nested plain washer, pressure spring and hexagon nut in proper order on the round pin connecting rod side of the support section of bolt extension board, the screw thread end of round pin connecting rod links to each other with round pin head screw thread. When the pin head is used, after the pin head is inserted into a correct position, the pin handles can be positioned in the positioning holes by pulling the pin handles on the left side and the right side, so that the bolt is prevented from loosening during vibration. When the bolt is opened, the bolt can be opened conveniently only by pulling the pin handle to the middle position of the positioning hole under the thrust of the pressure spring. The utility model discloses an electric power engineering car hatch door bolt structural installation is firm, and simple structure has self-locking function, guarantees can not the virtual inserting to can not become flexible because of vibrations, improved the security performance of hatch door greatly.
Description
Technical Field
The utility model relates to an electric power engineering car hatch door bolt structure.
Background
The electric engineering vehicle has complex use working conditions and is generally operated in the field. The electric engineering vehicle rear cargo compartment is frequently used, a cargo compartment door needs to be provided with a quick and simple opening bolt for opening and closing the compartment door, and the existing bolt has a plurality of defects: when in use, the inserting rod is inserted into the pin hole, and the inserting pin hole is too short to form virtual insertion; the inserted rod inserted into the pin hole can exit from the pin hole due to bumping and vibration in the driving process of the electric engineering vehicle; the bolt is often in the middle of shaking, and the life of bolt is short, and easy inefficacy causes the potential safety hazard.
Disclosure of Invention
The utility model aims at providing a simple structure, firm, the safe in utilization's of installation electric power engineering car hatch door latch structure.
The utility model discloses a power engineering car hatch door bolt structure, including bolt extension board, round pin handle, round pin connecting rod, round pin head, its characterized in that, round pin handle pass locating hole and round pin connecting rod one end threaded connection on the bolt extension board, and the other end of round pin connecting rod is opened there is the external screw thread, has nested plain washer, pressure spring and hexagon nut in proper order on the round pin connecting rod side of the support section of bolt extension board, and the screw thread end of round pin connecting rod links to each other with round pin head screw thread.
The utility model discloses a power engineering car hatch door bolt structure, during the use, after the round pin head inserted the correct position, control both sides and dial round pin handle and can fix a position round pin handle in the locating hole, prevent that the bolt is not hard up when vibrations. When the bolt is opened, the bolt can be conveniently opened only by pulling the pin handle to the middle position of the positioning hole under the thrust of the pressure spring, and the elasticity of the pressure spring can be adjusted through the moving position of the hexagon nut.
The utility model discloses an electric power engineering car hatch door bolt structural installation is firm, and simple structure has self-locking function, guarantees can not the virtual inserting to can not become flexible because of vibrations, improved the security performance of hatch door greatly.
