Example Embodiment

[0022] The implementation of the present invention will be described in detail below with reference to the drawings.

[0023] Such as figure 1 , figure 2 with image 3 As shown, the buckle-type cable explosion-proof box of this embodiment includes an explosion-proof box body 1 composed of a first box body 11 and a second box body 12, and a card is provided between the first box body 11 and the second box body 12. The buckle-type connection fitting 2 includes a first vertical beam 21, a second vertical beam 22 and a connecting beam 23. The first vertical beam 21 is fixed to the first box body 11, and the second vertical beam 22 is fixed to The second box body 12 is arranged in parallel with the first vertical beam 21, and the connecting beam 23 passes through the first vertical beam 21 and is connected to the second vertical beam 22 to connect the first box body 11 and the second box body 12 into one body. When installing and tightening the buckle-type cable explosion-proof box, the connecting beam 23 is inserted into the explosion-proof box body 1 and connected to the second vertical beam 22 after passing through the first vertical beam 21 to realize the fastening of the explosion-proof box. The operation is simple.

[0024] Among them, the first box body 11 and the second box body 12 can choose a variety of materials, such as stainless steel, glass fiber reinforced plastic, epoxy resin, etc., which can be selected according to actual application scenarios.

[0025] Such as figure 1 with image 3 As shown, the snap-fit connection fitting 2 is provided inside the explosion-proof box body 1, and the outer wall of the explosion-proof box body 1 is provided with a mounting hole 10 for inserting and installing the connecting beam 23.

[0026] Such as figure 1 As shown, the middle part of the explosion-proof box body 1 in this embodiment is provided with trapezoidal protrusions protruding laterally to both sides, and the two trapezoidal protrusions are arranged symmetrically. In order to achieve a firm connection between the first box body 11 and the second box body 12, such as figure 1 As shown, the top edges of the two trapezoidal protrusions in this embodiment ( figure 1 The middle is the left and right sides) are installed with snap-on connection fittings 2, and a pair of beveled edges ( figure 1 The center is a pair of hypotenuses in the upper left corner and the lower right corner) are installed with snap-on connection fittings 2. The height of the first vertical beam 21 and the second vertical beam 22 is designed according to the thickness of the explosion-proof box body 1 in actual use, and the length of the connecting beam 23 is designed according to the edge width of the explosion-proof box body 1 in actual use.

[0027] In order to improve the connection firmness of the connecting beam 23 and the first vertical beam 21, such as figure 2 As shown, in this embodiment, the first vertical beam 21 is provided with a threaded through hole 211, and the connecting beam 23 passes through the threaded through hole 211 of the first vertical beam 21 and is threadedly fitted with the threaded through hole 211, so that the connecting beam 23 It is firmly connected with the first vertical beam 21.

[0028] In order to facilitate the determination of the connection stroke of the connecting beam 23, such as figure 2 As shown, the second vertical beam 22 is provided with a threaded blind hole 221, and the end of the connecting beam 23 is threadedly fitted with the threaded blind hole 221.

[0029] Such as figure 2 As shown, the snap-fit connection fitting 2 includes two connecting beams 23, and the two connecting beams 23 are arranged in parallel, so that the two connecting beams 23 respectively pass through the first vertical beam 21 and are connected to the second vertical beam 22 to form a quadrilateral structure By combining the design of the first box body 11 and the second box body 12 with this structure, the first box body 11 and the second box body 12 can be firmly fixed.

[0030] Compared with the traditional bolt fastening method, the snap-on cable explosion-proof box of this embodiment is easy to operate and greatly saves construction time. The use of the snap-type cable explosion-proof box of this embodiment can effectively improve the installation efficiency of the cable explosion-proof box and provide a convenient method for on-site installation of the cable explosion-proof box.

[0031] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments. All technical solutions under the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications made without departing from the principles of the present invention should also be regarded as the protection scope of the present invention.
