[0005] The above technical solution has the advantages that: in the above technology, when the lock body needs to be hooked and matched with the floor lock bolt, the operator pulls the pull belt to make the pull belt drive the lock leaf to swing, thereby realizing the swinging of the lock hook, and the space between the lock hook and the movable groove gradually expands to facilitate the placement of the floor lock bolt in the space, that is, the inner wall of the bent part of the lock hook forms a first lock opening, and the space between the first lock opening and the movable groove is a first lock cavity, which gradually expands to facilitate the placement of the floor lock bolt, thereby improving the efficiency and precision of the hook lock and the floor lock bolt, and avoiding the phenomenon that the two are stuck together, which requires the operator to shake the seat to adjust the position between the two; in the above technology, the auxiliary hook is arranged to cooperate with the lock hook to realize the reinforced positioning of the floor lock bolt, the inner wall of the bent part of the auxiliary hook forms a second lock opening, and the space between the second lock opening and the movable groove is a second lock cavity, when the floor lock bolt is placed in the first lock cavity and matched with the first lock opening, it will also be placed in the second lock cavity and matched with the second lock opening, thereby realizing the synchronous hooking and matching of the lock hook and the auxiliary hook on the floor lock bolt, thereby improving the locking strength and precision of the cushion lock, and the bent direction of the auxiliary hook is opposite to the bent direction of the lock hook, so that the auxiliary hook and the lock hook cooperate to realize the clamping and positioning of the floor lock bolt, thereby improving the hooking strength of the floor lock bolt, and the auxiliary hook and the lock hook are arranged in a staggered manner to avoid the phenomenon of knocking or sticking when the floor lock bolt is placed; in the above technology, the synchronous piece is arranged to drive the auxiliary hook to swing synchronously when the lock hook swings, that is, the relative gap between the first lock opening and the second lock opening gradually expands with the driving of the synchronous piece, thereby improving the smoothness of the placement of the floor lock bolt; in the above technology, the lock body and the base are arranged on the automobile frame or component, and the floor lock bolt is arranged on the seat, that is, the two are opposite, and the relative position of the floor lock bolt and the lock body can be adjusted according to the actual automobile assembly and production requirements, that is, when the demand decreases, the lock body and the base are arranged on the seat, and the floor lock bolt is arranged on the automobile frame or component, and the connection mode is a conventional connection mode, so it will not be described in detail.

[0006] The utility model further sets up: movable groove left side inner wall is provided with fixed shaft, one end of fixed shaft is rotatably connected with the shaft, the shaft is arranged on the fixed shaft coaxially, movable groove right side inner wall is seted up with the hole that the shaft passes, the shaft is rotatably connected in the hole, the shaft passes out the hole and is connected with the auxiliary board end setting, reset structure includes the reset torsional spring of setting on the shaft, one end of reset torsional spring is connected with the deformation end, and the other end is connected with the stress end, the deformation end is connected with the lock body end setting, the stress end is connected with the fixed shaft setting.

[0007] The advantages of adopting the above technical solution are as follows: In the above technology, the lock body is movably mounted on the insertion shaft. When the lock body swings, it applies a force to the deformation end, causing the deformation end to bend under force. The force-bearing end is connected to the fixed shaft, so that when the pull strap is not pulled or stops pulling, the force applied by the deformation end is released and drives the lock body to swing back to its original position, thereby completing the swing back of the lock hook. Then, when the floor bolt is inserted into the first lock cavity, the lock hook automatically resets to complete the hooking and engaging movement. At the same time, it will continuously apply a force to the lock body to ensure that the lock hook and the floor bolt are stably hooked and engaged. In the above technology, the rotating shaft is connected to the auxiliary plate so that the auxiliary plate can move.

[0008] The present invention further comprises: the synchronizing element including a main gear coaxially connected to the rotating shaft and a secondary gear coaxially connected to the insert shaft, wherein the main gear and the secondary gear are meshed.

[0009] The advantages of adopting the above technical solution are as follows: When the lock body swings, the lock body will drive the insertion shaft to rotate. When the insertion shaft rotates axially, the auxiliary gear rotates synchronously. Because the auxiliary gear meshes with the main gear, the rotation of the auxiliary gear will drive the main gear to rotate synchronously, which in turn will drive the rotating shaft to rotate. This causes the rotating shaft to drive the auxiliary plate to swing, thereby expanding the relative gap between the first lock cavity and the second lock cavity, which facilitates the insertion of the floor bolt. At the same time, when the lock body swings back to its original position driven by the return torsion spring, it will also drive the insertion shaft to rotate synchronously to its original position, which in turn causes the main gear and the auxiliary gear to rotate synchronously to their original positions. This achieves the swinging back of the auxiliary hook, thereby achieving the hooking and engagement of the auxiliary hook and the lock hook with the floor bolt.

[0010] The present invention further comprises: the radial cross section of the auxiliary plate is arranged in an arc shape, and the highest point of its arc is located near the insertion shaft.

[0011] The advantages of adopting the above technical solution are: the radial cross section of the auxiliary plate is set in an arc shape and its highest point of arc is set close to the insertion shaft, so that its swing range is large, thereby increasing the relative gap between the first locking cavity and the second locking cavity. At the same time, when the auxiliary plate swings at its maximum amplitude, it avoids collision between the auxiliary hook and other external components, thus achieving the effect of a compact structure.

[0012] The present invention further includes: a force-bearing groove is provided at the bottom of the lock body, and a force-bearing shaft is connected between the inner walls on both sides of the force-bearing groove; one end of the pull strap is sleeved on the force-bearing shaft.

[0013] The advantage of adopting the above technical solution is that the setting of the force shaft and force groove in the above technology makes it easier for the operator to drive the lock body to swing when pulling the strap, thereby improving the driving efficiency.
