Description

Semi-hidden carriage lock

Technical Field

The utility model relates to a tricycle technical field, concretely relates to semi-hidden carriage lock.

Background

In the freight tricycle, a carriage is required to be arranged on a frame of the freight tricycle for carrying cargos; the common carriage structure comprises a carriage front plate, a carriage left side plate, a carriage right side plate, a carriage bottom plate and a carriage tail plate, and a carriage lock is usually arranged between the carriage left side plate and the carriage front plate for opening and locking the carriage left side plate and the carriage right side plate on two sides in order to load and unload goods; the existing carriage lock usually uses a hook type carriage lock as shown in fig. 5, the lock body of the carriage lock is often fixedly connected to the side wall of a carriage front plate, the left side plate and the right side plate of the carriage are often made of square steel due to strength, the peripheral ring of the left side plate and the right side plate of the carriage is made of iron sheet, and the residual space between the peripheral ring of the left side plate and the right side plate of the carriage and the inner coaming is wasted.

Through actual use and practical feedback, the existing hook type carriage lock is completely exposed on one side of a carriage front plate, but the national standard has strict requirements on the size of a carriage of a tricycle, so that the width of a lock body has to be taken into consideration during design, and a certain cargo carrying space is wasted; on one hand, the hook type lock body is locked by designing a hanging lug, and the locking strength is low; on the other hand, parts (such as springs) in the lock body are exposed for a long time and are easy to corrode, so that the experience is poor, and the service life is short.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a semi-hidden carriage lock to improve the life of carriage lock, promote the tricycle cargo carrying performance.

In order to achieve the purpose, the utility model provides a semi-hidden carriage lock, this carriage lock include fixed block, lock core and be used for driving the actuating mechanism of the flexible removal of lock core, fixed block middle part processing has the slide opening that allows the lock core to pass through, the lock core can freely slide in this slide opening, and lock core one end by about the carriage in the sideboard stretches into the carriage front bezel, the lock core other end with actuating mechanism swing joint.

According to foretell carriage lock, remove through actuating mechanism drive lock core, and the lock core can be by about the carriage sideboard stretch into the carriage front bezel, make lock core monoblock hide about the carriage sideboard, sideboard and car add body locking about the carriage directly through the lock core, the life of locking intensity and lock body has been improved, and whole lock body is installed about the carriage in the sideboard, be located about the carriage in the space between sideboard peripheral board and the interior bounding wall, make this space by make full use of, make the lock body can not occupy the carriage size, the performance of tricycle that carries cargo has been promoted.

According to an advantageous feature of the car lock described above: a limiting shaft shoulder is further processed at one end of the lock cylinder, which is far away from the driving mechanism, and a reset spring is sleeved on the lock cylinder between the limiting shaft shoulder and the fixed block; through the arrangement of the reset spring, a pulling force is generated when the driving mechanism resets, and resetting and locking are facilitated.

An advantageous embodiment of the car lock according to the above is: actuating mechanism includes articulated piece and the piece of dialling of "L" column structure, articulated piece one end with the lock core is articulated, the other end of articulated piece with dial the piece articulated, dial piece one end articulated to the carriage on the sideboard about, the other end of dialling the piece freely stretches out, freely stretches out of the piece and serves the handle that is provided with plastics material or rubber material. When the locking that resets, rotates and dials the piece, articulated piece this moment moves towards the lock core free end, can freely stretch at reset spring this moment to pulling force of parameter, and then make the lock core can be smooth and easy stretch into the carriage front bezel by the carriage about, overall structure design benefit, the low preparation of cost of manufacture easily.
