[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figure 1 A gate slot locking device includes a locking seat 1, and a locking block 2, a locking shaft 3, a wrench 4, a shaft end baffle 5 and a rotating cylinder 7 installed on the locking seat 1. The locking devices are installed on the top of both sides of the gate slot 9. To ensure the stability of the gate 8, the two sets of locking devices are installed on the same horizontal plane.

[0028] Reference Figure 3 , Figure 4 and Figure 5 To ensure the stability of the locking device, steel plates are pre-embedded on the top of both sides of the gate slot 9, that is, steel plates 6 are pre-embedded at the stress points of the locking block 2 and the gate slot 9. The locking seat 1 is fixed to the steel plate by the base connecting bolts. The mounting surface of the locking seat must be flat, and there should be operating space on both sides of the gate slot 9.

[0029] Reference Figure 1 and Figure 2 The locking seat 1 is designed in a "U" shape. The bottom of the locking seat 1 is a horizontal plane that contacts the pre-embedded steel plates 6 on the top of both sides of the gate slot. The two sides of the locking seat 1 are fixed to the steel plates 6 using connecting bolts or pins. A rotating cylinder 7 is set in the middle of the locking seat 1. A locking shaft 3 is horizontally inserted through the center of the rotating cylinder 7. Shaft end baffles 5 are detachably installed on both sides of the locking seat 1 and outside the locking shaft 3 by bolts or pins. Slots are formed on both sides of the locking shaft 3, and the shaft end baffles 5 can be inserted into the slots of the locking shaft 3 to fix the locking shaft 3.

[0030] Reference Figure 1 and Figure 2The locking block 2 is installed on the outside of the rotating drum 7. The locking block 2 is designed in an "L" shape. The locking block 2 can protrude from the locking seat 1 and extend into the side wall of the gate. The locking block 2 is set in an arc shape facing the outside of the gate. When the locking block 2 is rotated to be perpendicular to the gate 8, the locking block 2 can lock the gate 8 on both sides of the gate 8, thereby realizing the locking block 2 locking the gate 8.

[0031] Furthermore, when the gate 8 is opened to the locked position, the operator rotates the locking block 2 by 90°, and the gate 8 falls onto the locking block 2. When locking is not required, the operator lifts the gate body and rotates it 90° in the opposite direction to rotate the locking block 2 to the top, thus releasing the gate body from the locking device without removing it. This structure achieves gate locking by the jamming of the locking shaft 3 by the shaft end baffle 5.

[0032] Reference Figure 1 A wrench 4 is installed on the outside of the rotating drum 7 to drive the rotating drum 7 to rotate.

[0033] The specific operating principle of this application is as follows:

[0034] The locking seat 1 is fixed to the top of the gate slot 9 by the base connecting bolts. Steel plates are pre-embedded at the stress points of the locking block 2 and the gate slot 9. The mounting surface of the locking seat 1 must be flat. There should be operating space on both sides of the gate slot 9. The outer side column of the gate that needs to be locked should be equipped with a locking baffle to cooperate with the locking block 2. The locking block 2 supports the locking baffle and plays a supporting role.

[0035] The locking device comprises a locking seat 1, a locking block 2, and a locking shaft 3. The locking seat 1 is fixed to the top of the gate slot via base connecting bolts. When the gate is opened to the locked position, the operator rotates the locking block 2 90°, causing the gate to fall onto the locking block 2. When locking is not required, the operator lifts the gate body and rotates it 90° in the opposite direction to bring the locking block 2 to the top, thus releasing the gate body from the locking device without disassembling it.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
