[0027] Refer to Figures 1-6 , a guardrail buckle of the present utility model includes a main buckle body 1 and a sub-buckle body 2 that cooperates with the main buckle body 1. A locking tongue 11 is provided in the main buckle body 1 and is arranged towards the sub-buckle body 2. On one side of the sub-buckle body 2 close to the main buckle body 1, a locking opening 21 that cooperates with the locking tongue 11 is provided. An elastic member 12 for driving the locking tongue 11 to move towards the sub-buckle body 2 is provided in the main buckle body 1. A first pressing member 13 for cooperating with the locking tongue 11 to control the locking tongue 11 to move away from the locking opening 21 is provided on the lower side of the main buckle body 1. The first pressing member 13 is slidably arranged vertically on the lower side of the main buckle body 1. When the main buckle body 1 is pressed, the locking tongue 11 can move away from the locking opening 21, so as to separate from the locking opening 21. A second control member 14 that cooperates with the first pressing member 13 is further provided on the main buckle body 1. A sliding groove 15 adapted to the second control member 14 is provided on the main buckle body 1. The second control member 14 is slidably arranged reciprocally in the sliding groove 15. A first convex portion 131 is provided on the first pressing member 13, and a second limiting block 141 adapted to the first convex portion 131 is provided on the second control member 14;

[0028] The second control member 14 includes a first state and a second state in the sliding groove 15. When the second control member 14 is in the first state, the second limiting block 141 abuts against the first convex portion 131, and the first pressing member 13 cannot be pressed. When the second control member 14 is in the second state, the second limiting block 141 is staggered with the first convex portion 131, and the first pressing member 13 can press and control the locking tongue 11 to move away from the locking opening 21; and the second control member 14 is kept in the first state under normal conditions to keep the second control member 14 locked. In this embodiment, by setting the second control member 14 to cooperate with the first pressing member 13, the first pressing member 13 is used to control the locking tongue 11, and the second control member 14 can lock the first pressing member 13. It is necessary to unlock the second control member 14 first to control the locking tongue 11 to open through the first pressing member 13. With double insurance, it is safer, avoiding the locking tongue 11 being accidentally touched by the first pressing member 13 to cause it to open, and improving stability.

[0029] Preferably, one end is hinged to the main buckle body 1.

[0030] Refer to Figure 5 and Figure 6 , the second control member 14 includes an inner sliding frame 142 slidably disposed in the main buckle body 1 and a manual control portion 143 penetrating through the main buckle body 1 and connected to the inner sliding frame 142, and the second limiting block 141 is disposed on the inner sliding frame 142.

[0031] Refer to Figure 5 and Figure 6 , the elastic member 12 is disposed between the inner sliding frame 142 and the locking tongue 11, and one end of the elastic member 12 is connected to the locking tongue 11 and the other end is connected to the inner sliding frame 142. In this embodiment, one end of the elastic member 12 is disposed on the inner sliding frame 142, so that the elastic member 12 can cooperate with the inner sliding frame 142 to apply an elastic force to the inner sliding frame 142, enabling the inner sliding frame 142 to automatically reset and remain in the first state. One elastic member 12 can simultaneously apply an elastic force to the locking tongue 11 and the inner sliding frame 142, making full use of the elastic member 12, with a simple structure and low cost.

[0032] Refer to Figure 5 and Figure 6 , a first conical surface 1311 is provided on the first convex portion 131, a through groove 111 adapted to the first convex portion 131 is provided on the locking tongue 11, and a second inclined surface 112 cooperating with the first conical surface 1311 is provided in the through groove 111. When the first pressing member 13 is pressed, the first conical surface 1311 can cooperate with the second inclined surface 112 to squeeze the first conical surface 1311, thereby causing the locking tongue 11 to displace in a direction away from the locking opening 21.

[0033] Refer to Figure 1 and Figure 3 , a third inclined surface 22 cooperating with the locking tongue 11 is provided on the side of the auxiliary buckle body 2 near the side of the locking opening 21. When the main buckle body 1 is not connected to the auxiliary buckle body 2, when the locking tongue 11 moves towards the third inclined surface 22, the third inclined surface 22 can squeeze the locking tongue 11 to compress the locking tongue 11 inward, facilitating its entry into the locking opening 21. Embodiment 2

[0034] Refer to Figure 7 , a guardrail of the present utility model includes a fixed railing body 3 and a railing door 4. One side of the railing door 4 is hinged to the fixed railing body 3, and the other side is provided with the main buckle body 1 as described in Embodiment 1 or 2. The fixed railing body 3 is provided with an auxiliary buckle body 2 near the main buckle body 1.

[0035] The working process of the present utility model:

[0036] During the operation of a guardrail buckle of the present utility model, in the daily state, the elastic member 12 drives the lock tongue 11 to extend and drives the second control member 14 to maintain the first state. When it is necessary to control the retraction of the lock tongue 11, first drive the second control member 14 to slide along the sliding groove 15 to switch it to the second state, and the second limit stop 141 and the first convex portion 131 are staggered. Then press the first pressing member 13. When pressing the first pressing member 13, the first conical surface 1311 can cooperate with the second inclined surface 112 to squeeze the first conical surface 1311, so that the lock tongue 11 is displaced away from the lock port 21, and the lock tongue 11 and the lock port 21 can be separated.

[0037] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The electric slide rail slider, cylinder, welding machine, electric telescopic rod, and internal components of the controller all adopt conventional models in the prior art, and their internal structures belong to the prior art structures. Workers can complete the normal operation of them according to the prior art manual. Coupled with the circuit connection adopting the conventional connection method in the prior art, no specific description will be made here.

[0038] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields are all included in the patent protection scope of the present utility model.
