Description

Technical Field

[0001] The utility model relates to the field of side-pull boxes, in particular to a hydraulic transmission self-locking structure. Background Art

[0002] The side box of the OB vehicle needs to be fixed during transportation to prevent it from sliding out and causing danger; when it arrives at the place of use, the side box needs to be pulled out smoothly for normal use. The existing side box locking device is equivalent to a large manual latch.

[0003] The existing side-pull box locking device mainly fixes the side-pull box by manually operating the latch. During transportation, the operator needs to manually insert the latch into the locking hole to ensure that the side-pull box does not slide out.

[0004] However, this manual latching method is not only cumbersome to operate, but also prone to human factors causing the latch to not be properly inserted or forgotten, thus causing safety hazards. Therefore, a hydraulic transmission self-locking structure is now proposed. Utility Model Content

[0005] In order to improve the problem that the latch has potential safety hazards and is complicated to operate, the utility model provides a hydraulic transmission self-locking structure.

[0006] The utility model provides a hydraulic transmission self-locking structure, which adopts the following technical solutions:

[0007] A hydraulic transmission self-locking structure, comprising a fixed plate, the inner wall of which is installed with a fixing bolt, and a connecting plate is fixed to one side of the outer wall of the fixed plate, the inner walls of the two connecting plates are connected with supporting bolts, and a buckling mechanism is provided between the supporting bolts located between the two connecting plates;

[0008] The snap-fit ​​mechanism includes a rotating plate, which is rotatably connected to the outside of the supporting bolts between the two connecting plates, and a snap-fit ​​block is fixed to one end of the rotating plate, a mounting shell is fixed below the front end of the fixed plate, and a hydraulic cylinder is passed through the inner wall of the mounting shell, a pushing block is connected to the power output end of the hydraulic cylinder, and a moving rod is connected to the top of the pushing block.

[0009] By adopting the above technical solution, through the cooperation of the hydraulic pump and the hydraulic cylinder inside the installation shell, the pushing block drives the moving rod to push the rotating plate to move.

[0010] Optionally, the rotating plate forms a rotating structure with the connecting plate through supporting bolts, and the rotating plate fits tightly with the moving rod.

[0011] By adopting the above technical solution, under the fixed support of the connecting plate and the supporting bolts, the rotating plate is pushed to rotate, so that the locking block is locked with the locking bolt.

[0012] Optionally, a limiting mechanism is provided on one side of the pushing block, and the limiting mechanism includes an upper connecting plate, which is fixed above the mounting shell at the front end of the fixed plate, and a limiting groove is provided on the inner wall of the upper connecting plate, and the limiting plate is fixed on the outer wall of the moving rod at a position above the limiting groove.

[0013] By adopting the above technical solution, the moving rod is allowed to fit the upper connecting plate and slide stably through the limiting plate.

[0014] Optionally, the limiting mechanism also includes a lower connecting plate, which is fixed below the mounting shell at the front end of the fixed plate, and a slide groove is provided at the top of the lower connecting plate, and a roller is embedded in the position of the slide groove at the bottom end of the pushing block.

[0015] By adopting the above technical solution, the roller slides along the slide groove, thereby improving the smoothness and stability of the sliding process of the push block, and avoiding excessive friction that affects the sliding.

[0016] Optionally, the moving rod penetrates into the interior of the limiting groove, and a sliding structure is formed between the moving rod and the limiting groove.

[0017] By adopting the above technical solution, the limit groove allows the moving rod to slide stably along with the pushing block, thus avoiding deviation or shaking.

[0018] Optionally, a reset mechanism is provided on one side of the rotating plate, and the reset mechanism includes a pressing plate, which is fixed to the outer wall of the rotating plate at one end away from the snap-fit ​​block, and an inclined plate is fixed to the outer wall of the pressing plate facing the fixed plate, and the outer wall of the inclined plate is connected to a rubber pad.

[0019] By adopting the above technical solution, the inclined plate tilts when it is pressed, so that the rotating plate rotates, and the buckle block is separated from the locking bolt.

[0020] Optionally, the pressing plate is connected to the inclined plate by welding, and the inclined plate is connected to the rubber pad by bonding.

[0021] By adopting the above technical solution, the rubber pad can be used to prevent the inclined plate from colliding with the broadcast vehicle or causing damage.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model fixes the self-locking structure to the transmission vehicle through the fixing plate and the fixing bolts. The hydraulic pump and the hydraulic oil cylinder embedded in the mounting shell cooperate to push the push block to make the moving rod fit, and press the rotating plate to rotate, so that the buckle block can quickly engage the locking bolt, and the side pull box is self-locked to improve safety and stability, avoiding the cumbersome and troublesome manual latch. The rotating plate can be stably rotated through the cooperation and support of the connecting plate and the supporting bolts to avoid looseness and the inability to dock with the locking bolts;

[0024] 2. The utility model improves the stability of the sliding process by sliding the roller along the slide groove of the lower connecting plate when the push block slides, avoiding shaking or deviation, which affects the pushing of the rotating plate. The moving rod follows the push block and slides along the limit groove in the upper connecting plate, further improving the stability of the sliding process, and cooperates with the limit plate to fit on the upper connecting plate, avoiding the loosening of the push block and the moving rod, which causes the misalignment with the rotating plate.

[0025] 3. When the side pull box needs to be opened, the utility model resets the hydraulic pump and the hydraulic cylinder inside the installation shell by cooperation, so that the push block drives the moving rod to reset, thereby contacting and pushing the pressing plate, and rotating through the inclined side of one end of the inclined plate, so that the snap-fit ​​block can be disengaged from the locking bolt, so that the side pull box can be opened, avoiding the troublesome form of manual latching, and at the same time, the rubber pad bonded to the inclined plate can avoid collision with the broadcast vehicle during rotation or bonding.
