Description

Technical Field

[0001] The utility model relates to the technical field of braided hoses, in particular to a steel wire braided hose for coal mines. Background Art

[0002] The wire braided hoses used in the coal mining industry are mostly connected by threaded connection.

[0003] However, after the end of the hose is connected to other pipes, the end of the hose is directly exposed to the outside without corresponding protection. Even non-professionals can easily rotate the end of the hose to disassemble the hose.

[0004] Therefore, it is necessary to improve the traditional braided hose so that it can prevent the risk of disassembly by non-professionals to a certain extent. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a wire braided hose for coal mines.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wire braided hose for coal mines comprises a tube body, a connecting tube is fixed on the tube body, and the end of the connecting tube is rotatably connected to a rotating sleeve which is threadedly connected to other pipes, the connecting tube is slidably connected to the through hole of the round sleeve, and the round sleeve is sleeved on the rotating sleeve, a spring is sleeved on the connecting tube, and a limiting member for limiting the round sleeve is provided on the tube body.

[0008] Preferably, the limit member includes a fixed plate fixedly connected to the tube body, the fixed plate is provided with a sliding hole and a circular groove, the round sleeve is provided with a screw hole, the screw hole is threadedly connected to a screw rod, the screw rod is slidably connected to the sliding hole, and the end of the screw rod is adapted to the circular groove.

[0009] Preferably, one end of the spring abuts against the side wall of the circular sleeve, and the other end abuts against the side wall of the tube body.

[0010] Preferably, an elastic rubber gasket protrudes from the portion where the end of the screw rod abuts against the circular groove.

[0011] Preferably, when the circular sleeve is sleeved outside the rotating sleeve, the inner wall of the circular sleeve does not contact the outer wall of the rotating sleeve.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The present application protects the rotating sleeve by putting the round sleeve on the rotating sleeve under the elastic force of the spring, thereby effectively preventing the rotating sleeve from being directly exposed to the outside, effectively increasing the difficulty of disassembling the rotating sleeve and other pipes, and preventing non-professionals from disassembling the hose. Under the protection of the round sleeve, the rotating sleeve can also be prevented from being damaged by direct collision with foreign objects.

[0014] 2. When the screw rod of the present invention contacts the circular groove, the circular sleeve cannot be moved and separated from the rotating sleeve due to external force, which protects the rotating sleeve and prevents the circular sleeve from being exposed to the outside due to the movement of the circular sleeve due to force.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] The utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A steel wire braided hose for coal mines comprises a pipe body 1, a connecting pipe 2 is fixed on the pipe body 1, and the end of the connecting pipe 2 is rotatably connected to a rotating sleeve 3 connected to other pipes by threads, the connecting pipe 2 is slidably connected to a through hole 5 of a round sleeve 4, and the round sleeve 4 is sleeved on the rotating sleeve 3, a spring 6 is sleeved on the connecting pipe 2, and a limiting member for limiting the position of the round sleeve 4 is provided on the pipe body 1. One end of the spring 6 abuts against the side wall of the round sleeve 4, and the other end abuts against the side wall of the pipe body 1. Under the elastic force of the spring 6, the round sleeve 4 can be moved to be sleeved outside the rotating sleeve 3, so that the rotating sleeve 3 is hidden. When the round sleeve 4 is sleeved outside the rotating sleeve 3, the inner wall of the round sleeve 4 does not contact the outer wall of the rotating sleeve 3, so the rotating sleeve 3 will not cause wear to the rotating sleeve 3 during rotation.

[0024] Embodiment 2:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiter includes a fixed plate 9 fixedly connected to the tube body 1, and a sliding hole 10 and a circular groove 11 are provided on the fixed plate 9. A screw hole 7 is provided on the circular sleeve 4, and a screw rod 8 is connected to the screw hole 7 by a thread. The screw rod 8 is slidably connected to the sliding hole 10, and the end of the screw rod 8 is adapted to the circular groove 11. An elastic rubber gasket protrudes from the part where the end of the screw rod 8 abuts against the circular groove 11. When the screw rod 8 is slidably connected to the sliding hole 10, the circular sleeve 4 can be pushed to move, causing the circular sleeve 4 to separate from the rotating sleeve 3, so that the rotating sleeve 3 is exposed. When the screw rod 8 abuts against the circular groove 11, the circular sleeve 4 cannot be moved and separated from the rotating sleeve 3 due to external force, and the rotating sleeve 3 is protected at this time.

[0026] In summary, after the rotating sleeve 3 provided in this embodiment is connected to other pipes through threads, the pressure on the round sleeve 4 can be released. Under the elastic force of the spring 6, the round sleeve 4 is sleeved on the rotating sleeve 3 to protect the rotating sleeve 3. The screw rod 8 is rotated until the end of the screw rod 8 is separated from the sliding hole 10. Then the round sleeve 4 is rotated so that the end of the screw rod 8 is aligned with the circular groove 11. The screw rod 8 is rotated until the end of the screw rod 8 is in contact with the circular groove 11. At this time, the position of the round sleeve 4 is fixed, and the round sleeve 4 stably protects the rotating sleeve 3.

[0027] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
