Description

Technical Field

[0001] The utility model relates to the field of pipeline clamping accessories, in particular to a rubber clamping device which is convenient for locking. Background Art

[0002] With the development of society, equipment and materials in various fields have been greatly improved. Pipes are common items in people's daily lives. They are mainly composed of pipes, pipe connectors and valves to transport gas, liquid, fluid and other devices. Clamps are often used to fix the pipe joints in the connection between pipes. Clamps include: metal clamps, rubber clamps, etc. Among them, rubber clamps use the elasticity of rubber itself to seal the pipe joints or add metal fixings on the outside to fix them, which can play a good fixing and sealing effect. Rubber clamps are generally composed of a stainless steel outer lining and a rubber inner sleeve.

[0003] The existing rubber clamping device has the following shortcomings:

[0004] 1. Generally, the butt joints at both ends of the stainless steel outer lining opening are fixedly connected by bolts, which is time-consuming and laborious to disassemble and assemble, reducing the disassembly and assembly efficiency of the clamp, making it inconvenient to quickly lock the connection between the two pipes.

[0005] 2. There is usually no protective structure designed on the outer wall of the docking piece. The bolts are prone to rust after being corroded by rainwater, causing the threads to get stuck, making subsequent replacement very inconvenient.

[0006] 3. Existing rubber clamps are usually a combination of a rubber inner sleeve and a stainless steel outer lining. Since there is no limiting structure designed on the outer wall of the rubber, it is directly fitted with the stainless steel lining. When tightening the bolts, the rubber inner sleeve is softer than the stainless steel lining and is prone to displacement, thereby reducing the sealing effect of the connection between the two pipes. Utility Model Content

[0007] The utility model aims to provide a rubber clamping device which is convenient for locking.

[0008] To achieve this purpose, the utility model adopts the following technical solutions:

[0009] Provided is a rubber clamping device that is easy to lock, comprising a stainless steel outer liner, and two butt joint pieces are integrally formed on the outer wall of the stainless steel outer liner;

[0018] Preferably, an outer wall of one end of the latch away from the docking piece is provided with an oblique angle.

[0019] Preferably, the top and bottom ends of the rubber inner sleeve are both fixedly provided with ribs.

[0020] Beneficial effects of the utility model:

[0021] 1. The novel device uses a locking mechanism, namely a latch, a wedge-shaped locking tongue and a telescopic component, and a snap-on plug-in structure, so that after the stainless steel liner is put on the connection between the two pipes and the two butt pieces are fitted, the wedge-shaped locking tongue can automatically engage and lock with the wedge-shaped locking groove on the outer wall of the latch. Compared with the prior art, bolt fixation is avoided, the locking speed of the two butt pieces is improved, and the connection between the two pipes is quickly locked. At the same time, the pull plate and the anti-slip plate are designed to realize the rapid withdrawal of the wedge-shaped locking tongue and the release of the latch, so that the clamping device can be quickly disassembled from the connection between the two pipes, thereby improving the disassembly and assembly efficiency of the device.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0034] Reference Figures 1 to 6 As shown, a rubber clamping device that is easy to lock includes a stainless steel outer liner 1. The stainless steel outer liner 1 has a certain bending performance, so it is convenient to first open it and then put the pipe on it. The outer wall of the stainless steel outer liner 1 is integrally formed with two docking pieces 2;

[0035] It also includes a rubber inner sleeve 3 and a locking mechanism;

[0036] The rubber inner sleeve 3 is sleeved on the outer wall of the stainless steel outer liner 1. The outer wall of the rubber inner sleeve 3 is provided with an annular groove 4 for the stainless steel outer liner 1 to be inserted. The annular groove 4 provides an installation space for the stainless steel outer liner 1 on the rubber inner sleeve 3, so that the stainless steel outer liner 1 is firmly inserted on the outer wall of the rubber inner sleeve 3 and is not easy to fall off.

[0037] The locking mechanism is arranged on the outer wall of the stainless steel outer lining 1, and the locking mechanism includes a latch 5, a wedge-shaped lock tongue 6 and a telescopic component 7. The latch 5 is fixedly arranged on the outer wall of one of the docking pieces 2, and the telescopic component 7 is arranged on the outer wall of the other docking piece 2. The wedge-shaped lock tongue 6 is fixedly arranged on the telescopic component 7, and a wedge-shaped lock groove 8 for inserting the wedge-shaped lock tongue 6 is provided on the outer wall of the latch 5.

[0038] Reference Figures 1 to 6As shown, the telescopic assembly 7 includes a slider 9, two slide bars 10 and two tightening springs 11, one of which is fixedly provided with a limit block 12 on the outer wall of the docking piece 2 away from the latch 5, and the two slide bars 10 are slidably arranged on the outer wall of the limit block 12, the slider 9 is fixedly arranged between the ends of the two slide bars 10 away from the limit block 12, each tightening spring 11 is sleeved on the outer wall of one slide bar 10, the limit block 12 and the slider 9 respectively contact the two ends of each tightening spring 11, the wedge-shaped lock tongue 6 is fixedly connected to the end of the slider 9 away from the slide bar 10, and an avoidance groove 13 for the latch 5 to pass through is provided on the outer wall of the other docking piece 2, and the width of the avoidance groove 13 is greater than the width of the latch 5. When it is necessary to seal the connection between the two pipes, first, the two docking pieces 2 are opened by both hands, so that the stainless steel lining 1 is deformed, and when the stainless steel lining 1 is sleeved to the connection between the two pipes through the opening between the two docking pieces 2, the two docking pieces 2 are tightened, and at this time, the latch 5 is When the latch pin 5 contacts the wedge-shaped lock tongue 6, the wedge-shaped lock tongue 6 is slidably connected to the limit block 12 through the slider 9 and the two slide bars 10. Each of the abutting springs 11 is sleeved with a slide bar 10. The limit block 12 and the slider 9 respectively abut against the two ends of each abutting spring 11, so that the abutting force generated when the latch pin 5 contacts the wedge-shaped lock tongue 6 drives the two abutting springs 11 to contract, thereby driving the wedge-shaped lock tongue 6 to slide toward one end close to the limit block 12. When the plug block continues to approach until the wedge-shaped locking groove 8 thereon is aligned with the wedge-shaped locking tongue 6, the wedge-shaped locking tongue 6 is no longer resisted by the outer wall of the latch pin 5, but slides right to reset and directly inserts into the wedge-shaped locking groove 8, thereby locking the latch pin 5, and then locking the two docking pieces 2, further driving the stainless steel outer lining 1 to tighten the rubber inner sleeve 3, and sealing and fixing the connection between the two pipes through the rubber inner sleeve 3. Compared with the existing bolt fixing method, the locking speed is faster, thereby improving the locking efficiency.

[0039] Reference Figures 1 to 6 As shown, one end of the two slide bars 10 away from the slide block 9 is fixedly connected with an anti-slip plate 14, and a pull plate 15 is fixedly provided on the outer wall of the anti-slip plate 14. When the clamping device needs to be replaced, the pull plate 15 is manually grasped and pulled toward the end away from the rubber inner sleeve 3. Since the anti-slip plate 14 and the slide block 9 are respectively fixedly connected to the two ends of each slide bar 10, the slide block 9 and the wedge-shaped locking tongue 6 thereon are driven to be pulled out from the wedge-shaped locking groove 8 of the latch pin 5 through the anti-slip plate 14 and the two slide bars 10, thereby releasing the latch pin 5, so that the wedge-shaped locking tongue 6 no longer locks the latch pin 5. Since the latch pin 5 is fixedly connected to one of the docking pieces 2, the two docking pieces 2 can be manually opened to open the stainless steel outer lining 1, and then removed from the connection between the two pipes, so as to facilitate the replacement of a new clamping device.

[0040] Reference Figures 1 to 6As shown, two slide grooves 16 are fixedly provided on the outer wall of the other docking piece 2, and a protective cover 17 is slidably provided between the two slide grooves 16. In the normal state, the protective cover 17 covers and protects the locking mechanism to prevent the locking mechanism from being rusted by contact with rainwater, etc., which is beneficial to prolonging the service life of the locking mechanism and reducing the maintenance cost and locking cost. The protective cover 17 cooperates with the two slide grooves 16 to enable it to have a quick-release performance. When the clamping device needs to be replaced, the protective cover 17 is first slid down from the two slide grooves 16 to expose the locking mechanism, and then the locking mechanism is unlocked to realize the disassembly and replacement of the clamping device.

[0041] Reference Figures 1 to 6 As shown, a plurality of anti-skid strips 18 are arranged at equal intervals on the outer wall of one end of the rubber inner sleeve 3 away from the docking piece 2, and each anti-skid strip 18 is fixedly connected to the rubber inner sleeve 3. The plurality of anti-skid strips 18 can increase the friction between the rubber inner sleeve 3 and the two pipe connections, thereby increasing the installation tightness between the rubber inner sleeve 3 and the two pipe connections, and further increasing the installation effect of the clamping device and the two pipe connections, making it less likely to fall off.

[0042] Reference Figures 1 to 6 As shown, a plurality of blocks 19 are evenly spaced on the outer wall of the rubber inner sleeve 3 near the docking piece 2, and a plurality of slots 20 are evenly spaced on the outer wall of the stainless steel outer lining 1. Each block 19 is engaged with a slot 20, and each block 19 is a triangular structure. When assembling the stainless steel outer lining 1 and the rubber inner sleeve 3, the plurality of blocks 19 are first aligned with the plurality of slots 20, and the retaining edge 22 at the top end of the rubber inner sleeve 3 can be pushed away and embedded in the top end of the stainless steel outer lining 1, and then the retaining edge 22 at the bottom end of the rubber inner sleeve 3 can be pushed away and embedded in the bottom end of the stainless steel outer lining 1, thereby realizing the assembly of the rubber inner sleeve 3 and the stainless steel outer lining 1, and then making the plurality of blocks 19 engaged with the plurality of slots 20, and each block 19 is a triangular structure. After being inserted into the slot 20, it is not easy to fall out, which is similar to the barb function on a fishing hook.

[0043] Reference Figures 1 to 6 As shown, an outer wall of one end of the latch pin 5 away from the docking piece 2 is provided with an oblique angle 21. The oblique angle 21 can reduce the friction generated when the latch pin 5 contacts the outer wall of the wedge-shaped lock tongue 6 when the latch pin 5 passes through the avoidance groove 13 and contacts the wedge-shaped lock tongue 6, thereby reducing the wear of the latch pin 5 and the wedge-shaped lock tongue 6, which is beneficial to extending the service life of the two, and at the same time enables the wedge-shaped lock tongue 6 to be inserted into the wedge-shaped lock groove 8 more quickly.

[0044] Reference Figures 1 to 6 As shown, the top and bottom ends of the rubber inner sleeve 3 are fixed with retaining edges 22, which can limit the top and bottom ends of the stainless steel outer liner 1, thereby preventing the rubber inner sleeve 3 from falling off from the stainless steel outer liner 1 and improving the tightness of the insertion between the two.
