Description

Technical Field

[0001] This utility model relates to the field of quick-connect coupling technology, and in particular to a quick-connect coupling with a spring sheath. Background Technology

[0002] In a pneumatic system, a pneumatic component is a component that performs work by using the force generated by the pressure or expansion of gas, that is, a machine that converts the elastic energy of compressed air into kinetic energy. A pneumatic component is a form of power transmission and also an energy conversion device that uses gas pressure to transmit energy. Pneumatic system pipelines usually require quick-connect couplings for connection.

[0003] Existing quick-connect fittings lack any protective measures at the connection point between the hose and the fitting, making the connection prone to buckling and affecting the service life of the hose. To solve the above problems, a quick-connect fitting with a spring sheath is provided to protect the connection point between the hose and the quick-connect fitting. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a quick-connect fitting with a spring sheath.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-connect fitting with a spring sheath includes a fitting body and a plug body, wherein the plug body is inserted into one end of the fitting body to achieve quick connection of a gas pipeline.

[0007] The connector body has a fixing sleeve at one end, and a spring sheath at the other end, which is fitted onto the gas hose.

[0008] Preferably, a rotating ring is rotatably connected to the inner limiting sleeve, and a rotating block is movably connected to the rotating shaft.

[0009] Preferably, the inner end of the rotating block is provided with an abutment block, which abuts against the circumferential sidewall of the connector body.

[0010] Preferably, the end face of the rotating ring is provided with a plurality of rotating shafts at equal angles, and the rotating block is rotatably connected around the rotating shafts.

[0011] Preferably, the outer end of the rotating block is provided with a second limiting post, and the end face of the fixed sleeve is provided with a second limiting groove, and the second limiting post is slidably connected in the second limiting groove.

[0012] Preferably, the side wall of the fixed sleeve is movably connected to a first limiting post, and the rotating ring is provided with a first limiting groove, wherein the first limiting post is slidably connected within the first limiting groove.

[0013] Preferably, a threaded rod is rotatably connected to the side wall of the fixed sleeve, and a movable block is threadedly connected to the threaded rod, the movable block being fixedly connected to the first limiting post.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Fix the fixing sleeve to the connector body, and then fit the spring sleeve onto the hose. When the pipe bends, the spring sleeve can provide cushioning to prevent the gas hose from buckling and ensure the hose's lifespan.

[0016] 2. Rotating the threaded rod can drive the moving block to move. The first limiting post and the first limiting groove can only slide relative to each other to drive the rotating ring to rotate, thereby driving the rotating block to rotate around the rotating shaft. This causes the abutting block to press against the side wall of the cylindrical end, thus fixing the fixing sleeve to the joint body. No processing of the joint body is required, and disassembly is convenient.

[0017] In summary, this utility model overcomes the shortcomings of the prior art and has a reasonable design. By setting a spring sleeve at the end of the quick-connect fitting and having the spring sleeved on the gas pipeline, it can prevent the gas hose from buckling and protect the gas hose. It has high social use value and application prospects. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Reference Figure 1-4 A quick-connect fitting with a spring sheath includes a fitting body 1 and a plug body 2, wherein the plug body 2 is inserted into one end of the fitting body 1 to achieve quick connection of a gas pipeline.

[0027] The other end of the connector body 1 is connected to the gas hose and is a cylindrical end 101. A fixing sleeve 3 is provided on the cylindrical end 101. A spring sheath 31 is provided at the end of the fixing sleeve 3. The spring sheath 31 is fitted onto the gas hose and can be used to protect the gas hose from breaking and ensure the service life of the hose.

[0028] Furthermore, a rotating ring 33 is rotatably connected to the inner limit of the fixed sleeve 3. Several rotating shafts 331 are provided at equal angles on the end face of the rotating ring 33. A rotating block 332 is rotatably connected to the rotating shaft 331. An abutment block 333 is provided on the inner end of the rotating block 332. The abutment block 333 abuts against the circumferential side wall of the cylindrical end 101. By the multiple abutment blocks 333 being distributed at equal angles and abutting against the cylindrical end 101, the fixed sleeve 3 can be fixed on the cylindrical end 101.

[0029] Furthermore, a second limiting post 334 is provided at the outer end of the rotating block 332, and a second limiting groove 325 is provided at the corresponding position of the end face of the fixed sleeve 3 and the second limiting post 334. The second limiting post 334 is slidably connected in the second limiting groove 325. While the rotating ring 33 rotates relative to the fixed sleeve 3, it can push the rotating block 332 to rotate around the rotating shaft 331, thereby driving the abutting block 333 to press against the side wall of the cylindrical end 101.

[0030] The fixed sleeve 3 has a connecting frame 321 on its side wall. A threaded rod 322 is rotatably connected to the connecting frame 321. A moving block 323 is threadedly connected to the threaded rod 322. A first limiting post 324 is provided at the bottom of the moving block 323. A first limiting groove 335 is provided on the rotating ring 33 at a position corresponding to the first limiting post 324. The first limiting post 324 is slidably connected in the first limiting groove 335.

[0031] Working principle: When in use, rotating the threaded rod 322 can drive the moving block 323 to move. The first limiting post 324 and the first limiting groove 335 slide relative to each other, which can drive the rotating ring 33 to rotate, thereby driving the rotating block 332 to rotate around the rotating shaft 331. This causes the abutting block 333 to press against the side wall of the cylindrical end 101, which can fix the fixing sleeve 3 to the connector body 1. No processing of the connector body is required, and disassembly is convenient.

[0032] The fixing sleeve 3 is fixed on the connector body 1, and the spring sleeve 31 is sleeved on the hose. When the pipe bends, the spring sleeve 31 can provide cushioning to prevent the gas hose from buckling and ensure the life of the hose.
