The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.

The utility model provides a novel locking structure which comprises a key assembly 1 and a buckle 2 which are movably connected, wherein the key assembly 1 can drive the buckle 2 to be close to or far away from a turntable 3, and the buckle 2 can limit the turntable 3 when being close to the turntable 3 so as to prevent the turntable 3 from rotating.

In this structure, can realize locking and release to carousel 3 through the button subassembly 1 to buckle 2 position's regulation, and then reach nimble regulation haulage rope length's purpose.

Example 1:

as shown in fig. 1-8, this embodiment provides a novel locking structure, including button subassembly 1 and buckle 2 that rotate the connection, wherein button subassembly 1 can drive buckle 2 and be close to or keep away from carousel 3 under the pressing of external force to realize spacing or release to carousel 3, can stop rotating when carousel 3 is spacing, reach the purpose of control haulage rope length.

The locking structure comprises a shell 4, the internal structure of the locking structure is as shown in fig. 1 and 3, a mounting groove 41 is formed on the shell 4, the key assembly 1 is rotatably mounted in the shell 4, part of the structure of the key assembly 1 protrudes outwards relative to the mounting groove 41 and forms a pressing part 11, an elastic piece 5 is mounted below the key assembly 1, and the elastic piece 5 is in a compressed state. When no external force is applied, the key assembly 1 can be positioned at the mounting groove 41 and partially protruded with respect to the mounting groove 41 by the pushing of the elastic member 5. The turntable 3 is fixedly arranged in the shell 4, and the buckle 2 is movably arranged between the key assembly 1 and the turntable 3 through the key assembly 1.

Specifically, a platform-like structure for mounting and fixing the elastic member 5 is formed in the housing 4, and the elastic member 5 is fixedly mounted under the key assembly 1 through the structure. When the key assembly 1 is pressed, the elastic member 5 can be compressed by the pressing force.

In this embodiment and other similar embodiments, the elastic member 5 is a spring.

When the turntable 3 rotates and drives the traction rope to retract through the paying-off opening 42, as shown in fig. 1 (the traction rope is not drawn in the drawing), the buckle 2 is far away from the turntable 3 under the drive of the key assembly 1, and the turntable 3 rotates clockwise and can push the buckle 2 to rotate or deflect towards a direction far away from a rotating path of the turntable 3; when the haulage rope outwards stretches and drives the turntable 3 to rotate anticlockwise, if the key assembly 1 is pressed downwards at this moment, the buckle 2 moves along with and approaches the turntable 3 to the position where the rotating path entering the turntable 3 is located, and at this moment, the buckle 2 can directly contact the turntable 3 and limit the turntable 3, so that the effect of preventing the turntable 3 from continuing to rotate is achieved, and the purpose of controlling the length of the haulage rope is achieved.

In this embodiment, the left side of the key assembly 1 is rotatably connected to the housing 4, and the right side is limited in the housing 4, and the overall structure thereof is shown in fig. 6. The matching structure of the key assembly 1 and the buckle 2 is shown in fig. 5, and the buckle 2 is rotationally connected with the middle part of the key assembly 1.

As shown in fig. 7, the structure of the buckle 2 is that a limit groove 21 is formed on one side of the buckle 2 close to the key assembly 1, and the buckle 2 can rotate relative to the key assembly 1 through the limit groove 21.

In order to ensure that the buckle 2 does not affect the automatic rotation of the turntable 3 (i.e. the automatic recovery of the traction rope), as an alternative embodiment, an avoidance groove 22 is formed at one end of the buckle 2, which is directed to the turntable 3, and when the buckle 2 is far away from the turntable 3, the turntable 3 in a rotating state can push the buckle 2 to rotate towards a direction far away from the turntable 3 through the avoidance groove 22 so as to release the limit between the buckle 2 and the turntable 3.

The whole of the avoiding groove 22 has a curved surface structure with a certain radian, as shown in fig. 7. The structure of the turntable 3 is a prior art and will not be described herein.

When the key assembly 1 is used, the limiting function of the key assembly on the turntable 3 can be realized by continuously pressing the key assembly. In order to reduce the difficulty of operation and to facilitate the use of the locking structure, in this and other similar embodiments, the locking structure further comprises a locking mechanism 6 for restricting the movement of the key assembly 1. The locking mechanism 6 can limit the key assembly 1 when started, so that the key assembly is in a continuously pressed state, and a user can use the locking structure more conveniently.

Specifically, the lock mechanism 6 includes a lock button 61 and a lock post 62 that can be engaged with each other, and the lock post 62 is fixedly disposed in the housing 4. When the locking key 61 and the locking post 62 are clamped with each other, the key assembly 1 can be continuously in a pressed state under the action of the locking key 61 and the locking post 62, so that the key assembly 1 is limited to rotate relative to the shell 4, and the turntable 3 is further limited to rotate, as shown in fig. 1 and 2; when the lock key 61 is moved in a direction to release the engagement with respect to the lock post 62 by an external force, the lock on the key assembly 1 can be released so that the key assembly 1 can be rotated with respect to the housing 4, as shown in fig. 3 and 4.

Specifically, the locking slot 111 is a bar-shaped hole, and as shown in fig. 6, the locking key 61 can slide along the extending direction of the locking slot 111 with respect to the locking slot 111. The locking key 61 is inserted into the locking slot 111, a protruding structure which is convenient to push is formed at a portion of the locking key located outside the locking slot 111, a collar 611 sleeved on the locking post 62 is formed at a portion of the locking key located inside the casing 4 through the locking slot 111, and a limit step 612 is formed on the collar 611, and when the locking key 61 slides and moves relative to the locking slot 111, the limit step 612 can be clamped with the locking post 62.

In addition, the locking key 61 is located below the locking slot 111 and has a plate structure capable of matching with the lower surface of the locking slot 111, and the end of the structure is raised and forms a bump, and the bump can be matched with a groove of the housing 4 located at the periphery of the locking slot 111, so as to realize basic limitation of the locking key 61 and prevent the locking key 61 from sliding back and forth in the unlocked state. In the stationary state, the lock key 61 is fixed to the front side thereof with respect to the lock slot 111 by the above-mentioned mutually-fitted projections and grooves; when the locking key 61 is required to slide and fix the key assembly 1, the protrusion and the recess are required to be disengaged by pressing with force, and then the locking key 61 is pulled with force to slide towards the rear side of the locking slot 111, so as to achieve the locking with the locking post 62.

It should be noted that the locking key 61 can slide with respect to the locking slot 111 only when the key assembly 1 is in the pressed state, and can limit and release the key assembly 1, as shown in fig. 2 and 4.

It can be appreciated that under the cooperation of the buckle 2, the key assembly 1 and the locking mechanism 6, the locking structure can conveniently realize the limit and release of the turntable 3, thereby achieving the purpose of flexibly controlling the length of the traction rope. In the use process of the locking structure, the button assembly 1 can be sprung and locked smoothly, and has the advantages of safety, reliability and free retraction. Meanwhile, compared with the traditional tractor locking structure, the structure has the advantages of simplicity in installation, low processing cost and the like.
