[0027] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of the present application.

[0028] As shown in Figure 1 , the rubber hose with quick coupler comprises a hose body 1, and a first pipe body 2 and a second pipe body 3 are sleeved on the outer side of the hose body 1 to protect the hose body 1.

[0029] As shown in Figure 3 , the second pipe body 3 comprises a large pipe 31 and a small pipe 32 which are fixed to each other and coaxially communicated with each other, and the first pipe body 2 can be inserted into the large pipe 31, and the relative position between the large pipe 31 and the first pipe body 2 along the axial direction is adjustable, so that the total length of the first pipe body 2 and the second pipe body 3 can be adjusted to adjust the protection length of the hose body 1. Thus, the normal bending of the hose can be avoided due to the excessively long protection length, and the hose part to be protected can also be completely covered due to the excessively short protection length.

[0030] In the present embodiment, as shown in Figure 2 and Figure 3As shown, the inner diameter of the large tube 31 is in clearance fit with the outer diameter of the first tube body 2, the outer wall of the large tube 31 is provided with a limiting groove 34, the first tube body 2 is provided with a limiting plate 21, the limiting plate 21 is located in the limiting groove 34 and is in sliding fit with the limiting groove 34, so as to realize the sliding connection of the first tube body 2 and the large tube 31 in the axial direction thereof;

[0031] The large tube 31 is provided with two first fixing plates 33, the first screw rod 4 is rotatably connected between the two first fixing plates 33, the first screw rod 4 penetrates through the limiting block 21 and is in threaded connection with the limiting block 21, by rotating the first screw rod 4, the relative sliding of the large tube 31 and the first tube body 2 in the axial direction thereof can be realized, so as to adjust the protection length; and, in order to ensure that the relative position of the large tube 31 and the first tube body 2 is adjusted and kept stable, the first screw rod 4 needs to have self-locking property, that is, the thread angle of the first screw rod 4 is smaller than the equivalent friction angle.

[0032] Of course, the mode for driving the relative sliding of the large tube 31 and the first tube body 2 includes but is not limited to the first screw rod 4 and other structures in the embodiment, in some embodiments, a hydraulic cylinder, a telescopic rod and other linear driving components can also be arranged on the large tube 31 to directly drive the sliding of the limiting block 21 in the limiting groove 34, so as to realize the relative sliding of the large tube 31 and the first tube body 2.

[0033] The first tube body 2 and the small tube 32 are respectively provided with one limiting assembly 5, the two limiting assemblies 5 are in contact limiting with the hose body 1, so as to realize the limiting and fixing of the positions of the first tube body 2 and the second tube body 3 relative to the hose body 1, and ensure that the first tube body 2 and the second tube body 3 can always protect the corresponding positions of the hose body 1;

[0034] As shown in the figure, Figure 4 The limiting assembly 5 includes a fixing ring 51, the fixing ring 51 in the two limiting assemblies 5 is respectively fixed with the first tube body and the small tube 32; the fixing ring 51 is fixed with a mounting frame 52, the mounting frame 52 is provided with two connecting plates 53 capable of synchronous reverse sliding, one contact limiting block 54 is respectively fixed on the two connecting plates 53, the two contact limiting blocks 54 are close to each other and can be in contact with the surface of the hose body 1, the friction force is used to limit the movement, so as to avoid the arbitrary movement of the hose body 1 relative to the first tube body 2 and the second tube body 3, and affect the protection effect;

[0035] In the embodiment, the contact limiting block 54 is provided with an arc surface, the arc surface can be matched with the outer surface of the hose body 1 to improve the friction size; in other embodiments, a rubber pad is arranged on the arc surface to be in contact with the surface of the hose body 1, the contact friction coefficient is improved, and the friction force is further improved;

[0036] It should be noted that the clamping force of the contact limiting block 54 on the hose body 1 is smaller in this embodiment. Although the hose body 1 is made of rubber, it will not be easily completely clamped (there will be slight deformation) and affect gas transmission because the diameter of the hose body 1 (the air pipe connected to the air cylinder) is small. Therefore, the contact limiting block 54 and the hose body 1 mainly use friction to contact and limit.

[0037] In this embodiment, the two connecting plates 53 are both in sliding connection with the mounting frame 52, and the mounting frame 52 is provided with two second fixing plates 521, and the two second fixing plates 521 are rotatably connected with a second screw rod 55, as shown in Figure 5 The two ends of the second screw rod 55 are respectively provided with first external threads 551 and second external threads 552 with opposite rotation directions and equal pitches, and the first external threads 551 and the second external threads 552 respectively penetrate through the two connecting plates 53 and are in threaded connection with the two connecting plates 53. A motor is arranged on one of the second fixing plates 521 to drive the second screw rod 55 to rotate, so as to realize the synchronous reverse sliding of the two connecting plates 53.

[0038] In addition, in order to ensure that the positions of the two connecting plates 53 remain stable after adjustment, the second screw rod 55 needs to have self-locking property, that is, the thread angles of the first external threads 551 and the second external threads 552 are both smaller than the equivalent friction angle.

[0039] In addition, in this embodiment, the outer diameter of the small pipe 32 is equal to the outer diameter of the first pipe body 2, so as to facilitate the installation of the two fixing rings 51 with the small pipe 32 and the first pipe body 2 respectively.

[0040] In this embodiment, threaded holes are formed in the small pipe 32 and the first pipe body 2, and a through hole is formed in the mounting frame 53. By means of bolts penetrating through the through hole and being screwed into the threaded holes, detachable fixed connection between the two fixing rings 51 and the small pipe 32 and the first pipe body 2 can be realized, which facilitates the later disassembly and maintenance.

[0041] In other embodiments, the two fixing rings 51 and the small pipe 32 and the first pipe body 2 can also be fixed by welding or adhesive bonding.

[0042] Working principle:

[0043] By sleeving the first pipe body 2 and the second pipe body 3 outside the hose body 1, setting the large pipe 31 on the second pipe body 3 to mutually cooperate with the first pipe body 2 and being capable of adjusting along the axial direction, the total length of the first pipe body 2 and the second pipe body 3 can be adjusted to adjust the protection length of the hose body 1, so as to avoid that the protection length is too long to affect the normal bending of the hose, and also to avoid that the protection length is too short to completely cover the part of the hose needing protection. By setting a limiting component 5 on the first pipe body 2 and the small pipe 32 respectively and setting two contact limiting blocks 54 capable of synchronous reverse sliding in the limiting component 5 to contact the surface of the hose body 1 and realize contact limiting by using friction, the hose body 1 is prevented from being randomly moved relative to the first pipe body 2 and the second pipe body 3 to affect the protection effect.
