[0023] The utility model will be further described below in combination with the drawings and specific examples.
[0024] Example 1
[0025] As shown in Figure 1 , Figure 2 , Figure 3 , the terminal box with the anti-theft lock in the example comprises a box body 2, a box cover 1 connected by a hinge and an anti-theft lock mechanism for locking the box body 2 and the box cover 1. The box body and the box cover are both rectangular in shape. The box body 2 and the box cover 1 are hingedly connected at the side. The anti-theft lock mechanism is installed at the opposite side. When the box cover and the box body are combined, the anti-theft lock mechanism is used to lock the two to keep the box shape.
[0026] The anti-theft lock mechanism in the example comprises a lock seat 5 and a key 4. The lock seat 5 is fixed to the end face cavity wall of the box body 2. The tail end top surface of the lock seat 5 is formed with a lock hole 51. The top surface of the box cover 1 corresponding to the lock hole 51 is provided with a jack 3 for inserting the key 4. The hole wall of the lock hole 51 is outwardly protruded and formed with a flexible lock hook 52. As shown in Figure 1 , Figure 2 , the lock hook 52 is in the shape of an arc-shaped sheet. The lock hook 52 is preferably integrally formed with the lock seat 5, such as plastic material. Of course, the key can also be made of plastic or metal material according to the requirements. In order to improve the stability of the lock, the lock hook 52 is formed at the opposite position of the hole wall of the lock hole 51.
[0027] As shown in Figure 1 , Figure 5 , the key 4 is in the shape of a column. The upper top end of the key 4 is triangular. The lower peripheral wall of the key 4 is inwardly recessed to form a card slot 41 which cooperates with the lock hook. Similarly, the card slot 41 is formed at the opposite position of the lower peripheral wall of the key 4 to cooperate with the double lock hooks. The diameter of the key below the card slot 41 and adjacent to the card slot 41 is greater than the distance between the adjacent end portions of the lock hook 52, so as to limit the key in the axial direction by cooperating with the lock hook.
[0028] When the lower part of the key 4 passes through the jack and is inserted into the lock hole, the lock hook 52 is clamped into the card slot 41. When the key is pulled out, the side wall below the card slot abuts against the lock hook to form a limit, so as to axially lock the key. The upper top end of the key is exposed at the top opening of the jack. A tool cooperating with the triangular top end is used to apply force to the upper top end of the key to make it rotate to the dislocation position of the card slot and the lock hook. The cooperation between the card slot and the lock hook is released, so as to complete the axial unlocking. At this time, the key can be pulled out, and then the box cover is opened.
[0029] In order to pull out the key more easily, the shape of the key peripheral wall between the two card slots is changed to a pyramid 42 shape, as shown in the drawings, when the key is rotated to misalign the card slots with the lock hooks, the lock hooks 52 abut the pyramid 42 shaped peripheral wall between the two card slots 41, which helps to reduce the contact area with the lock hooks, thereby reducing the resistance of pulling out. Figure 5
[0030] In order to reduce the cost and weight, etc., a weight reduction groove 53 is formed on the lock seat 5 adjacent to the tail end lock hole 51, as shown in the drawings, to reduce the amount of material used. Figure 4
[0031] The connection hole 21 for the cable to enter and exit is located at the end of the box body 2 adjacent to the lock seat 5, and in order to improve the stability of the cable, a wire clamping seat 6 is also arranged in the cavity of the box body 2 corresponding to the position of the connection hole 21, so that the wire clamping seat 6 clamps the cable, the wire clamping seat 6 includes a seat body 63 integrally formed with the bottom wall of the box body 2, and a semi-ring shaped clamp 61 connected with the seat body 63 through fasteners, the clamp 61 is fixed on both sides of the seat body 63 through screw type fasteners at the position of the top surface groove cavity on both sides, the space surrounded by the clamp 61 and the top surface groove cavity of the seat body 63 is the wire clamping hole 62, the cable passes through the wire clamping hole, and is clamped by the clamp to improve the stability.
[0032] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution under the idea of the present application belongs to the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
