Description

Technical Field

[0001] The utility model relates to the technical field of rubber hose processing tooling, in particular to a diameter expanding tooling for installing a rubber water hose and a quick plug. Background Art

[0002] At present, the installation of rubber water hoses and quick plugs of different models requires expansion. The commonly used expansion method is usually to put the hose blank on the core rod with the expanded end, and then vulcanize and mold it. The end of the hose molded by this method will have uneven hose wall thickness and rubber overflow. The hose with rubber overflow is difficult to remove from the core rod after vulcanization and is easily damaged during the removal process.

[0003] In order to solve the above problems, a Chinese invention patent with announcement number CN104441600B in the prior art discloses a hose expansion tool, including a mandrel, an outer sleeve and an inner sleeve whose sizes match the mandrel, and a fixed head matching the size of the inner sleeve; the inner sleeve is composed of an inner sleeve wall and an inner sleeve seat, and the inner sleeve wall and the inner sleeve seat are fixed as one; the inner diameter of the outer sleeve is slightly larger than the outer diameter of the inner sleeve wall, and the radius difference is determined by the total thickness of the hose and the mandrel, the outer sleeve wall is stepped, and friction patterns that are beneficial to increasing friction are also provided on the outer side surface of the lower end of the outer sleeve wall; the fixed head is arranged below the inner sleeve seat, and the fixed head is composed of a fixed head body and a fixing bolt; the hose expansion tool avoids the overflow of rubber material, ensures the flatness of the expansion position, makes the wall thickness of the expansion position of the hose more uniform, reduces the production difficulty, improves the yield rate and production efficiency, and better saves production materials.

[0004] There are at least the following problems in this technology. The existing hose expansion tool consists of an outer sleeve, an inner sleeve and a fixed head. The fixed head is used to fix the core rod and the hose, but there is no fixing structure between the outer sleeve and the inner sleeve. Since the outer sleeve is directly sleeved on the outer side of the inner sleeve and the hose, the outer sleeve may be separated during the vulcanization process due to lack of stability, which reduces the stability of the tool and causes inconvenience in processing. Therefore, an expansion tool for the installation of rubber water pipes and quick plugs is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a diameter expansion tool for the installation of a rubber water pipe and a quick plug, which has the advantages of easy fixation and improved stability in use. It solves the problem that in the existing rubber hose diameter expansion tool, there is no fixed structure between the outer sleeve and the inner sleeve. Since the outer sleeve is directly sleeved on the outer side of the inner sleeve and the hose, during the vulcanization process, the outer sleeve may be separated due to lack of stability, thereby reducing the stability of the tool in use.

[0006] In summary, the present application provides the following technical solutions: a diameter expansion tool for installing a rubber water pipe and a quick plug, comprising an inner sleeve and an outer sleeve sleeved on the outer side of the inner sleeve, a sleeve seat being fixedly connected to the lower side of the inner sleeve, and an installation assembly being arranged between the sleeve seat and the outer sleeve;

[0007] The mounting assembly includes a mounting block fixedly connected to the bottom of the outer sleeve, a connecting shaft arranged inside the sleeve seat, a limit block connected to one end of the connecting shaft and extending to the inner side of the mounting block, an elastic assembly arranged on the outer side of the connecting shaft, and a pressing assembly arranged on the inner side of the mounting block.

[0008] The present application adopts the above-mentioned technical scheme, and flexibly adjusts the position of the limit block through the set elastic component. The cooperation of the limit block and the mounting block can realize the rapid fixation of the outer sleeve and the inner sleeve, thereby ensuring the stable combination of the outer sleeve and the inner sleeve, and reducing the possibility of loosening during the vulcanization expansion of the hose. At the same time, the pressing component is used to quickly separate the limit block from the mounting block, which facilitates the rapid disassembly of the outer sleeve. It is easy to use, greatly improves the stability of the expansion tooling, provides convenience for processing, and has good practicality.

[0009] Furthermore, the number of the mounting components is set to two groups, and the two groups of mounting components are symmetrically distributed on the left and right sides of the sleeve seat.

[0010] The beneficial effect of adopting the above further solution is that the two sets of installation components are provided to facilitate stable installation of the sleeve seat, thereby improving the fixing effect.

[0011] Furthermore, the elastic component includes a first spring sleeved on the outer wall of the connecting shaft and a second spring fixedly connected to an end of the connecting shaft away from the limiting block.

[0012] The beneficial effect of adopting the above further solution is that the first spring and the second spring can form a stable support for the connecting shaft and the limit block, and at the same time facilitate elastic adjustment of the positions of the connecting shaft and the limit block.

[0013] Furthermore, the first spring and the second spring are both located inside the sleeve seat, one end of the second spring away from the connecting shaft is fixedly connected to the inside of the sleeve seat, and a limiting component is arranged outside the first spring.

[0014] The beneficial effect of adopting the above further solution is that the provided limiting component can produce a limiting effect on the first spring.

[0015] Furthermore, the limit assembly includes a support plate fixedly connected between the connecting shaft and the limit block and a fixing ring sleeved on the outer wall of the connecting shaft, the fixing ring is fixedly connected to the interior of the sleeve seat, the first spring is located between the fixing ring and the support plate, and the two ends of the first spring are respectively abutted against the support plate and the fixing ring.

[0016] The beneficial effect of adopting the above further solution is that, through the cooperation between the fixing ring and the supporting sheet, the first spring can play a role of elastic support for the limit block, thereby facilitating the adjustment of the position of the limit block.

[0017] Furthermore, the limiting block is wedge-shaped in appearance, and the inclined surface of the wedge-shaped limiting block is arranged upward.

[0018] The beneficial effect of adopting the above further scheme is: by setting a wedge-shaped limit block, it is convenient to quickly cooperate with the installation block. When the installation block contacts the inclined surface of the limit block downward, it can push the limit block to move along the inner side of the sleeve seat, so that the subsequent limit block and the installation block can be connected relative to each other.

[0019] Furthermore, the pressing assembly includes a top block slidably mounted inside the mounting block and a pressing head fixed to one end of the top block, the pressing head extends to the outside of the mounting block, and one end of the top block away from the pressing head abuts against the limit block.

[0020] The beneficial effect of adopting the above further solution is: by pushing the pressing head, the top block can be driven to move, so that the top block can push the limit block, so as to move the limit block out of the installation block, thereby facilitating the rapid disassembly of the outer sleeve.

[0021] Furthermore, the upper and lower sides of the top block are fixedly connected with sliding blocks, a sliding groove is provided inside the mounting block, and the sliding block is slidably connected to the inner side of the sliding groove.

[0022] The beneficial effect of adopting the above further solution is that the top block can be easily adjusted to move left and right stably through the cooperation of the slider and the slide groove.

[0023] Furthermore, a heat-insulating sleeve is fixedly sleeved on the outer wall of the outer sleeve, and anti-slip grooves are arranged on the outer wall of the heat-insulating sleeve.

[0024] The beneficial effect of adopting the above further solution is that the heat-insulating sleeve can provide heat insulation to a local portion of the outer sleeve, and the anti-slip pattern can be used to increase friction, making it easier to take the outer sleeve.

[0025] Compared with the prior art, the present application provides a diameter expansion tool for installing a rubber water pipe and a quick plug, which has the following beneficial effects:

[0026] The expansion tool for installing the rubber water pipe and the quick plug can flexibly adjust the position of the limit block through the elastic component provided, and the cooperation of the limit block and the installation block can realize the rapid fixation of the outer sleeve and the inner sleeve, thereby ensuring the stable combination of the outer sleeve and the inner sleeve and reducing the possibility of loosening when the rubber hose is vulcanized and expanded. At the same time, the pressing component is used to quickly separate the limit block from the installation block, which facilitates the rapid disassembly of the outer sleeve. It is easy to use, greatly improves the stability of the expansion tool, provides convenience for processing, and has good practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, a mounting assembly is arranged between the sleeve seat 3 and the outer sleeve 2, and the mounting assembly includes a mounting block 4 fixedly connected to the bottom of the outer sleeve 2, a connecting shaft 5 arranged inside the sleeve seat 3, a limit block 6 fixed to one end of the connecting shaft 5 and extending to the inner side of the mounting block 4, an elastic assembly arranged outside the connecting shaft 5, and a pressing assembly arranged inside the mounting block 4.

[0033] It should be noted that the number of mounting components is set to two groups, and the two groups of mounting components are symmetrically distributed on the left and right sides of the sleeve seat 3. The two groups of mounting components are set to facilitate the stable installation of the sleeve seat 3 and improve the fixing effect.

[0034] It should be noted that the shape of the limit block 6 is wedge-shaped, and the inclined surface of the wedge-shaped limit block 6 is set upward. The wedge-shaped limit block 6 is convenient for quick cooperation with the mounting block 4. When the mounting block 4 contacts the inclined surface of the limit block 6 downward, the limit block 6 can be pushed to move along the inner side of the sleeve seat 3, so that the limit block 6 and the mounting block 4 can be connected accordingly.

[0035] In this embodiment, the elastic component includes a first spring 9 sleeved on the outer wall of the connecting shaft 5 and a second spring 10 fixedly connected to the end of the connecting shaft 5 away from the limit block 6, wherein the first spring 9 and the second spring 10 are both located inside the sleeve seat 3, the end of the second spring 10 away from the connecting shaft 5 is fixedly connected to the inside of the sleeve seat 3, and a limit component is arranged outside the first spring 9. The first spring 9 and the second spring 10 can form a stable support for the connecting shaft 5 and the limit block 6, and at the same time, it is convenient to elastically adjust the positions of the connecting shaft 5 and the limit block 6, and the limit component can produce a limiting effect on the first spring 9.

[0036] In this embodiment, the limit assembly includes a support sheet 11 fixedly connected between the connecting shaft 5 and the limit block 6 and a fixing ring 12 sleeved on the outer wall of the connecting shaft 5, the fixing ring 12 is fixedly connected to the inside of the sleeve seat 3, the first spring 9 is located between the fixing ring 12 and the support sheet 11, and the two ends of the first spring 9 are respectively in contact with the support sheet 11 and the fixing ring 12. Through the cooperation of the fixing ring 12 and the support sheet 11, the first spring 9 can play the role of elastic support for the limit block 6, which facilitates the adjustment of the position of the limit block 6.

[0037] In this embodiment, the pressing assembly includes a top block 7 slidably mounted inside the mounting block 4 and a pressing head 8 fixed to one end of the top block 7. The pressing head 8 extends to the outside of the mounting block 4, and one end of the top block 7 away from the pressing head 8 abuts against the limit block 6. By pushing the pressing head 8, the top block 7 can be driven to move, so that the top block 7 can push the limit block 6, so as to move the limit block 6 out of the mounting block 4, thereby facilitating the quick disassembly of the outer sleeve 2.

[0038] It should be noted that sliders 13 are fixedly connected to the upper and lower sides of the top block 7, a slide groove 14 is provided inside the mounting block 4, the slider 13 is slidably connected to the inner side of the slide groove 14, and the cooperation between the slider 13 and the slide groove 14 facilitates the stable left and right movement adjustment of the top block 7.

[0039] It should be added that an insulating sleeve 15 is fixedly sleeved on the outer wall of the outer sleeve 2, and anti-slip grooves 16 are arranged on the outer wall of the insulating sleeve 15. The insulating sleeve 15 can provide insulation for local parts of the outer sleeve 2, and the anti-slip grooves 16 are conveniently used to increase friction and facilitate taking.

[0040] The working principle of the above embodiment is:

[0041] When the present application is in use, during the process of expanding the diameter of the rubber water pipe, the outer sleeve 2 is sleeved on the outside of the inner sleeve 1, and the rubber pipe blank is installed in the interlayer between the outer sleeve 2 and the inner sleeve 1. When the outer sleeve 2 is docked with the inner sleeve 1, the elastic force of the first spring 9 and the second spring 10 is used to elastically adjust the position of the limit block 6, so that the mounting block 4 and the limit block 6 remain docked, thereby achieving rapid fixation of the outer sleeve 2 and the inner sleeve 1. During vulcanization expansion, the outer sleeve 2 and the inner sleeve 1 are not easily separated, thereby ensuring the stability of the processing. When the processing is completed and the outer sleeve 2 needs to be removed, the top block 7 is driven to move by pushing the pressing head 8, so that the top block 7 can push the limit block 6 to separate from the mounting block 4, so as to facilitate rapid disassembly of the outer sleeve 2 and easy use.
