[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0017] The present application provides a self-locking quick parking mechanism, including a turntable 1, a guide cylinder 2, a guide pin 3, a compression spring 4, a guide rod 5, a block 6, a support leg 7, and a guide groove 10. The guide cylinder 2 is hollow inside, open at the top, and has a guide groove 10 on the upper side wall. A guide pin 3 is adapted in the guide groove 10, and the guide pin 3 can be connected with a guide rod 5 by interference fit; the guide rod 5 is "T"-shaped, one end of which is located in the inner cavity of the guide cylinder and is fixedly connected to the turntable 1 by welding or the like, and the other end is ball-shaped after passing through the bottom wall of the guide cylinder, and the ball head end of the guide rod 5 is clamped in two blocks 6 and the support leg 7, and each block 6 and the support leg 7 are connected by a screw 9; a compression spring 3 is provided between the end of the guide rod 5 close to the turntable 1 and the bottom wall of the inner cavity of the guide cylinder 3.

[0018] like Figure 1-2As shown, the turntable 1 is pressed down to move the turntable 1 downward, driving the guide pin 3 to move downward in the guide groove 10 of the guide cylinder 2 to the lower end of the guide groove 10. At this time, the guide pin 3 is fixed at the lower end of the guide groove 10 to achieve self-locking; the downward movement of the turntable 1 also drives the guide rod 5 to move downward, so that the compression spring 4 is compressed, and the support leg 7 supports the ground to achieve parking. Figure 3 As shown, the turntable 1 is rotated in the opposite direction so that the turntable 1 moves upward under the action of the rebound force of the compression spring 4. When the guide pin 3 moves upward in the guide groove 10 of the guide cylinder 2 to the upper end of the guide groove 10, the guide pin 3 is fixed at the upper end of the guide groove 10 under the action of the rebound force of the compression spring 4, thereby realizing self-locking. At this time, the compression spring 4 is still in a compressed state, and the support leg 7 leaves the ground, thereby realizing parking release and self-locking.

[0019] Furthermore, a rubber pad 8 is provided at the bottom of the support leg 7 to enhance the stability of the parking self-locking.

[0020] Furthermore, the end of the guide rod 5 away from the turntable 1 is in the shape of a ball head and the lower half is in contact with the support foot 7. The central top of the support foot 7 is inwardly concave in an arc shape, and the arc of the concave is adapted to the shape and size of the ball head of the guide rod 5; the two sides of the top of the support foot 7 are each connected with a clamping block 6 by a screw 9, and the upper half of the ball head of the guide rod is clamped between the two clamping blocks 6. Since the ball head at the lower end of the guide rod 5 can rotate relative to the support foot 7, the support foot 7 can rotate within a small range, and cooperate with the rubber pad 8 to better fit the ground, thereby increasing the support area and further enhancing the stability of parking and self-locking.

[0021] Furthermore, the turntable 1 is in a "T" shape, with one end extending into the inner cavity of the guide cylinder 2 and connected to the guide rod 5, and the other end being located outside the guide cylinder 2, and the outer diameter of the end of the turntable 1 away from the guide rod 5 is larger than the inner diameter of the guide cylinder 2, so as to facilitate the forward and reverse rotation operation of the turntable 1.

[0022] Furthermore, an anti-skid pattern is provided on the outer peripheral wall of the turntable 1 away from the guide rod 5 to reduce hand slippage when the turntable 1 is rotated forward and reversely.

[0023] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
