Abstract
A novel traction pin self-locking system comprises a fixing plate, installation plates and a traction pin. The installation plates are arranged on the fixing plate in parallel from top to bottom. Round holes with the same diameter are formed in the same positions of the installation plates. A lock base is arranged on one side of the round hole of the uppermost installation plate, an automatic lock is disposed on the lock base, the inward end of the automatic lock is provided with a screw hole, the lock base penetrates through the screw hole of the automatic lock through a screw, the screw is fixed to the lock base, the automatic lock can rotate along the screw, a circular bead is chamfered on the lower portion of the inward end of the automatic lock, and a flat fillet is chamfered on the upper portion of the inward end of the automatic lock. A pull ring is welded to the upper portion of the traction pin, a cover plate is arranged on the lower portion of the pull ring, a boss is disposed on the lower portion of the cover plate, a round hole is further formed in the middle of the body of the traction pin, and a spring pin is disposed in the round hole. By means of the system, the traction pin can be automatically locked, manual operation is not needed, and the system is easy, quick and safe to use.
Description
Technical field
The present invention relates to fork truck technical field, be specifically related to a kind of novel traction pin self-locking system。
Background technology
Electrically propelled traction vehicle is plant equipment conventional in handling work, and its power resources are exactly the storage battery being assemblied on tractor。Along with social development, the powerful tractor of Large Copacity gets more and more, therefore loading is more and more heavier, but container to be still connected with headstock by tractor by towing pin, but it is heavier to be because container loading, existing a lot of towing pins are deviate from sometimes automatically, so needing towing pin locked, and current towing pin will move locked by armrest substantially, cumbersome。
Summary of the invention
It is an object of the invention to be in that to provide a kind of novel traction pin self-locking system, can automatically towing pin be carried out locked, it is not necessary to manually, simple and fast safety。
It is an object of the invention to be achieved through the following technical solutions: it includes fixing plate, installing plate, towing pin, described fixing plate is arranged with some installing plates from the top down in parallel, each installing plate same position all has the circular hole of same diameter, topmost the circular hole side of an installing plate is provided with lock, lock is provided with automatic lock, automatically lock one end inwardly has screw, lock is fixed on lock by screw rod through lock screw automatically, automatically lock can rotate along screw rod, described automatic lock is rounded down below one end inwardly, there is the straight angle top, it is welded with draw ring above described towing pin, draw ring is arranged below cover plate, cover plate is arranged below boss, circular hole is also had in the middle of described towing pin cylinder, circular hole is provided with spring catch。
Towing pin can be carried out locked by the present invention automatically, it is not necessary to manually, simple and fast safety。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is that the present invention assembles schematic diagram。
Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, technical scheme is further described in detail。
Embodiment: as shown in accompanying drawing 1-2, it includes fixing plate 1, installing plate 2, towing pin 3, described fixing plate 1 is arranged with some installing plates 2 from the top down in parallel, each installing plate 2 same position all has the circular hole of same diameter, topmost the circular hole side of an installing plate 2 is provided with lock 4, lock 4 is provided with lock 5 automatically, automatically lock 5 one end inwardly have screw, lock 4 is fixed on lock 4 by screw rod through lock 5 screws automatically, automatically lock 5 can rotate along screw rod, described automatic lock 5 is rounded down below one end inwardly, there is the straight angle top, it is welded with draw ring 6 above described towing pin 3, draw ring 6 is arranged below cover plate 7, cover plate 7 is arranged below boss 8, circular hole is also had in the middle of described towing pin 3 cylinder, circular hole is provided with spring catch 9。
The present invention is arranged on headstock by fixing plate, before locked, towing pin is extracted, then fixing device corresponding with installing plate for container is put in the space between installing plate, then again towing pin is obtained circular hole from installing plate and insert, when towing pin boss touches and automatically locks, automatically rotation is locked, towing pin is such that it is able to insert further downward, automatically reset is locked subsequently, at this moment towing pin cover plate covers in the side of locking automatically, in non-manual situation, lock will not rotate automatically, therefore towing pin boss will be blocked in always automatically lock lower section, thus playing the effect of locking automatically, the spring catch additionally arranged in circular hole in the middle of towing pin cylinder can automatically extend in non-manual situation, also the effect of locking automatically is simultaneously worked as。
Embodiment described above is the one preferably scheme of the present invention, not the invention of this reality is done any pro forma restriction, also has other variant and remodeling under the premise without departing from the technical scheme described in claim。
