DETAILED DESCRIPTION

[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Embodiment 1:

[0032] See also Figures 1 to 7As shown, a mining crimping mesh includes a woven mesh 1 and a protective round tube 2 used together, wherein the protective round tube 2 is arranged at the edge of the woven mesh 1, mainly playing the role of edge sealing; the material of the protective round tube 2 can be metal or plastic, as long as it has a hollow structure and realizes the edge sealing function;

[0033] The woven mesh 1 can be woven using existing technology; the woven mesh 1 includes a grid structure formed by a plurality of metal round wires 3 that are overlapped horizontally and vertically, and the metal round wires 3 are rolled to be wavy;

[0034] It should be noted that: in this embodiment, a clamping portion 4 needs to be provided at both ends of the metal round wire 3 to complete the matching connection with the protective round tube 2. The structure of the clamping portion 4 can be various. For example, the clamping portion 4 can be an annular clamping groove directly provided on the outer wall of the metal round wire 3; or the end of the metal round wire 3 can be covered with a limiting cap, and the material of the limiting cap can be metal or plastic, preferably a plastic material with anti-corrosion properties; since the limiting cap is coated on the outer wall of the metal round wire 3 and has a certain thickness, the stepped structure formed between the limiting cap and the body of the metal round wire 3 can be used as the clamping portion 4;

[0035] In order to cooperate and connect with the metal round wire 3, in this embodiment, it is necessary to open limiting notches 5 at intervals on the tube wall of the protective round tube 2, and the limiting notches 5 include a connected insertion port 6 and a limiting long groove 7, and the groove width of the limiting long groove 7 is smaller than the diameter of the insertion port 6; the end of the metal round wire 3 can extend into the interior of the hollow structure through the insertion port 6; the clamping part 4 can cooperate and clamp with the groove wall of the limiting long groove 7.

[0036] In summary, the operator can plug the protective round tube 2 into the end of the metal round wire 3, and then rotate the protective round tube 2 so that the protective round tube 2 and the metal round wire 3 are clamped together, and the end of the metal round wire 3 is sealed by using the hollow chamber of the round tube; based on the protective round tube 2, the edge sealing processing of all metal round wires 3 can be conveniently completed, which is simple and effective.

[0037] In order to facilitate the plug-in connection, the most preferred way in this embodiment is to ensure that the two ends of the metal round wire 3 are on the same axis.

[0038] In order to improve the clamping strength, the width of the groove wall of the limiting long groove 7 is gradually reduced, so that the clamping force gradually increases with the rotation of the protective circular tube 2, and the maximum width is the connection with the insertion port 6.

[0039] Embodiment 2:

[0040] The other structures of this embodiment are the same as those of Embodiment 1, except that:

[0041] In this embodiment, a connecting notch 8 is opened on the protective circular tube 2, and the protective circular tubes 2 of adjacent mining crimped wire mesh are connected by a connecting cap 9. The connecting cap 9 includes a cap cover 10 respectively buckled on the protective circular tube 2, and the cap cover 10 is provided with a limit block 11 corresponding to the corresponding protective circular tube 2. The limit block 11 is inserted into the hollow structure of the protective circular tube 2 and abuts against the inner wall of the hollow structure to complete radial limitation; the two limit blocks 11 are connected by a connecting block 12, and the connecting block 12 is located in the connecting notch 8, and the connecting block 12 completes the circumferential limitation.

[0042] In order to enhance the connection fit and avoid shaking at the connection, the utility model ensures that the outer wall of the limit block 11 fits the inner wall of the protective tube 2. For example, when the inner wall of the protective tube 2 is an arc-shaped structure, the outer wall of the limit block 11 is also an arc-shaped structure.

[0043] As a specific implementation, in the present invention, the outer edge of the cap 10 is fixedly connected to the protective tube 2 by screws. Of course, other connection methods are also possible, such as flange connection or welding.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
