Description

Technical Field

[0001] The utility model relates to the technical field of rubber hoses, in particular to a high-pressure steel wire braided rubber hose. Background Art

[0002] High-pressure steel wire braided rubber hoses are mainly used in the hydraulic systems of aircraft fuel, mine hydraulic supports, oilfield exploitation, and engineering machinery equipment.

[0003] However, when the existing high-pressure steel wire braided rubber hoses transport high-temperature kerosene in cold weather, they are easily affected by the outside world, resulting in a large amount of heat loss during the transportation process. When used in winter or low-temperature regions, they are prone to cracking, reducing the service life of the high-pressure steel wire braided rubber hoses.

[0004] Therefore, it is necessary to improve the traditional high-pressure steel wire braided rubber hose to add protection in a cold environment to prevent it from cracking. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-pressure steel wire braided rubber hose to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A high-pressure steel wire braided rubber hose includes a pipe body. A polygonal block is fixed on the pipe body, and the polygonal block is slidably connected to a polygonal groove opened on a heat preservation sleeve. A collar is sleeved on the pipe body, and a threaded hole is opened on the collar. The screw rod at the end of a round rod is threadedly connected to the threaded hole. A limiting member for limiting the round rod is provided on the heat preservation sleeve.

[0008] Preferably, the limiting member includes a fixed block fixed on the heat preservation sleeve. A threaded groove is opened on the fixed block. A disc is provided on the fixed block. Grooves are opened on the round rod in a circumferentially uniform distribution. A fixed rod is fixed on the disc. One end of the fixed rod is engaged with the groove, and the other end is threadedly connected to the threaded groove.

[0009] Preferably, a clamping groove is opened on the side wall of the heat preservation sleeve, and a clamping block adapted to the clamping groove is fixed on the collar.

[0010] Preferably, a circular groove is opened on the fixed block, and through holes adapted to the circular groove are opened on the disc. A plurality of the through holes are circumferentially equally angularly distributed on the disc. A vertical rod penetrates through the through hole, and the vertical rod is engaged with the circular groove.

[0011] Preferably, the end of the vertical rod is magnetically fixed to the circular groove.

[0012] Preferably, an elastic rubber ring protrudes from a part of the side wall of the collar that abuts against the polygonal block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the heat preservation sleeve is sleeved on the pipe body, and the polygonal groove opened on the heat preservation sleeve is slidably connected with the polygonal block on the pipe body. Therefore, it can play a positioning effect on the heat preservation sleeve, making the heat preservation sleeve unable to rotate under force, and the heat preservation sleeve can maintain its own position stability, thereby protecting the pipe body and effectively preventing the pipe body from being frozen and cracked due to too low environmental temperature.

[0015] 2. In this application, under the action of the fixed rod, it can play a limiting role on the round rod, making the round rod unable to rotate under force. Therefore, the screw rods at both ends of the round rod will not disengage from the screw holes on the collar, so the heat preservation sleeve can be more stably connected to the pipe body.
