Description

Technical Field

[0001] This application relates to the field of mechanical technology, and more specifically, to a pipe clamp. Background Technology

[0002] Currently, most automotive product piping is secured using standard pipe clamps. Standard pipe clamps have a relatively simple structure, formed from a single sheet of pressed iron. Figure 1 One example is shown.

[0003] Because the structural dimensions of ordinary pipe clamps cannot be adjusted, designers need to select different sizes of ordinary pipe clamps to fix them according to the outer diameter of different pipelines. The production line also needs to identify the pipe clamp model according to the drawings and select materials for assembly. Therefore, ordinary pipe clamps have poor applicability and high production costs.

[0004] Furthermore, since the inner diameter of ordinary pipe clamps is not adjustable, if its inner diameter is smaller than the outer diameter of the pipeline, for pipelines in areas with a liftable cab, when the cab is lifted, components such as the shift lever, parking brake cable, and brake lines need to move axially with the opening and closing of the cab. Overly tight clamps restrict this axial movement, posing a risk of the pipeline being pulled and broken. If the inner diameter of the ordinary pipe clamp is larger than the outer diameter of the pipeline, the pipeline fixation is relatively loose, lacking effective radial positioning and axial restraint, resulting in significant sway and a risk of dynamic interference. Additionally, for fixing components such as the shift lever and parking brake cable, since the cable mainly consists of an outer sheath and a spindle, with the outer sheath covering the spindle (e.g.,...),... Figure 2 As shown in the diagram, there is a certain amount of friction between the two. When the driver shifts gears or pulls the handbrake, the spindle will move axially within the outer casing to drive the gearbox shift arm or brake pads to perform the corresponding function. If the clamp does not adequately limit the axial movement of the outer casing, the outer casing will also move axially with the spindle due to the friction. In this case, the driver needs to pull a greater distance to make the spindle produce a larger displacement to compensate for the displacement of the outer casing, resulting in increased shifting and parking travel, thus reducing the driving experience.

[0005] In addition, ordinary pipe clamps require bolts and nuts to fix them to the sheet metal holes, which is complicated, wastes time and money, and the pipe clamps often rotate with the tightening force of the bolts, which cannot guarantee the accuracy of the pipeline installation angle, and the bolts are easy to loosen. Summary of the Invention

[0006] This application provides a pipe clamp with a radially extending flexible retaining spring disposed on a portion of the inner wall of a sleeve body. The end of the retaining spring abuts against the outer wall of the pipeline housed within the sleeve body, effectively limiting the radial movement of the pipeline and preventing dynamic interference. The flexibility of the retaining spring allows the pipe clamp to be used with pipelines of various outer diameters, achieving pipe clamp universality. On the other hand, the flexibility of the retaining spring allows the pipeline to move axially within the pipe clamp to a certain extent, preventing it from being pulled or even broken due to the inability to move axially. For components such as wire drawing parts, the retaining spring can also limit the outer skin by means of friction, reducing the travel of gear shifting or handbrake.

[0040] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0041] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0042] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0043] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0044] This application provides a pipe clamp with a radially extending flexible retaining spring disposed on a portion of the inner wall of a sleeve body. The end of the retaining spring abuts against the outer wall of the pipe housed within the sleeve body, effectively limiting the radial movement of the pipe and preventing dynamic interference. The flexibility of the retaining spring allows the pipe clamp to be used with pipes of various outer diameters, achieving pipe clamp universality. Furthermore, the flexibility of the retaining spring allows the pipe to move axially within the clamp, preventing pulling or even breakage caused by the inability to move axially. For components such as wire drawing parts, the retaining spring can also provide a certain degree of limitation on its outer surface through friction, reducing the travel of gear shifting or handbrake applications. In addition, the pipe clamp of this application can be quickly installed on the fixing component of the pipe clamp via a clamping mechanism, saving the time and cost of installation with bolts and nuts as with ordinary pipe clamps. It is also simple to disassemble and can be disassembled and reassembled multiple times.

[0045] like Figure 3-5 As shown, the pipe clamp provided in this application includes a sleeve 100, a plate-shaped long side 200, and a plate-shaped short side 300.

[0046] like Figure 5-10 As shown, the sleeve 100 includes a C-shaped sleeve body 110. The first end of the long side 200 and the first end of the short side 300 are respectively connected to the two ends of the sleeve body 110. The short side 300 fits against the long side 200, so that the long side 200, the short side 300 and the sleeve body 110 combine to form an approximately circular through hole for the pipeline to pass through. On the inner wall of the sleeve body 110, on the circumferential surface opposite to the long side 200, a plurality of flexible retaining rings 120 extending radially toward the central axis of the sleeve body 110 are fixed. The retaining rings 120 have a certain elasticity, and the ends of the retaining rings are retaining ring finger surfaces. During the deformation of the retaining rings 120, the retaining ring finger surfaces never protrude outside the sleeve body 110, which can prevent the fragile retaining ring finger surfaces from being damaged due to protrusion of the sleeve shell.

[0047] After the pipeline is inserted into the sleeve body 110, the end face of the snap ring finger abuts against the outer wall of the pipeline, giving the pipeline a certain radial clamping force and realizing the radial limit of the pipeline.

[0048] Preferably, the pipe clamp also includes a snap ring actuator 400. For example... Figure 5-10As shown, the snap ring actuator 400 includes an arc-shaped pusher 410 coaxially slidably disposed on the sleeve body 110. The arc-shaped pusher 410 is inserted into the sleeve body 110 from its first end and extends along the axial direction of the sleeve body 110. The snap ring actuator 400 also includes an arc-shaped protrusion 420 disposed on the outer circumferential surface of the arc-shaped pusher 410. The shape of the arc-shaped protrusion 420 is adapted to the shape of the arc-shaped pusher 410, and the arc-shaped protrusion 420 extends from its end away from the sleeve body 110 along the axial direction of the arc-shaped pusher 410 to the middle of the arc-shaped pusher 410. The arc-shaped protrusion 420 is a U-shaped hollow cavity, and an arc-shaped gap 4203 is provided between the side wall 4202 of the arc-shaped protrusion 420 facing the sleeve body 110 and the outer circumferential surface of the arc-shaped pusher 410.

[0049] like Figure 10 As shown, both ends of the sleeve body 110 are provided with radially extending arc-shaped flanges on their outer circumferential surfaces. The first arc-shaped flange 140 located at the first end of the sleeve body 110 passes through the arc-shaped gap 4203 and is engaged in the arc-shaped protrusion 420, so that the arc-shaped protrusion 420 can drive the entire snap ring driver to slide axially relative to the sleeve 100 without falling off.

[0050] Preferably, a first spring 430 is provided inside the arc-shaped protrusion 420. The first end of the first spring 430 is fixed on the side wall 4201 of the arc-shaped protrusion 420 away from the sleeve body 110, and the second end of the first spring 430 is fixed on the first arc-shaped flange 140.

[0051] Preferably, anti-slip patterns are provided on the outer surface of the second arc-shaped flange 130 at the second end of the sleeve body 110 and on the outer surface of the side wall 4201 of the arc-shaped protrusion 420 away from the sleeve body 110. The uneven surface increases the friction and facilitates manual operation.

[0052] When assembling the pipeline, the operator pinches the side wall 4201 and the second arc-shaped flange 130, causing the snap ring actuator to move axially along the sleeve body 110 and approach the second arc-shaped flange 130. At this time, the first spring 430 is compressed, and the arc-shaped push plate 410 presses the snap ring 120, causing it to undergo temporary deformation. After the snap ring is deformed, the finger surfaces of each snap ring move away from each other. At this time, the pipeline can be assembled into the pipe clamp, and the position of the pipeline can be adjusted axially.

[0053] After the axial position of the pipeline is adjusted, the operator loosens the side wall 4201 and the second arc-shaped flange 130. Under the elastic force of the first spring 430, the snap ring actuator moves away from the second arc-shaped flange 130. The clamping force of the snap ring actuator on the snap ring disappears, the snap ring deformation returns to normal, the snap ring finger tips approach each other, and the pipeline is clamped. The pipe clamp achieves radial fixation and a certain axial limitation of the pipeline. When the axial position of the pipeline needs to be adjusted again, simply tighten the side wall 4201 and the second arc-shaped flange 130 again.

[0054] After the pipeline is inserted into the pipe clamp, the spring force of the retaining spring keeps the pipeline tightly against the inner surface of the long side (200mm), effectively providing radial positioning and preventing dynamic interference caused by loose assembly. Simultaneously, because the spring force only increases friction and does not absolutely restrict the axial movement of the pipeline, in situations where pipelines with openings or closing mechanisms are fixed, the pipeline can experience some axial movement within the clamp, preventing pulling or even breakage due to impaired axial movement. For components like wire drawing parts, the retaining spring can also use friction to limit the outer surface, reducing the travel of gear shifting or handbrake applications. Due to the elasticity of the retaining spring, this pipe clamp can accommodate pipelines of different outer diameters, achieving universal installation for pipelines of various outer diameters.

[0055] The second ends of the long side 200 and the short side 300 are respectively provided with a coaxial first mounting hole 220 and a second mounting hole 320. After the long side 200 and the short side 300 are fitted together, the pipe clamp is fixed to its fastener (e.g., a sheet metal hole in a vehicle) through the first mounting hole 220 and the second mounting hole 320. Preferably, as shown... Figure 11-13 As shown, a first serration 210 is provided on the side of the long side 200 facing the short side 300, and a second serration 310 is provided on the side of the short side 300 facing the long side 200. The two serrations cooperate with each other to increase friction and improve the installation reliability of the pipe clamp.

[0056] As one embodiment, the pipe clamp also includes a clamping mechanism 500 that passes through the first mounting hole 220 and the second mounting hole 320. Figure 5-9 As shown in Figures 14-15, the clamping mechanism 500 includes a central shaft 510 and a positioning element 520. The first end of the central shaft 510 is provided with a plurality of clamping springs 540. The second end of the central shaft 510 passes through the first mounting hole 220 and the second mounting hole 320 in sequence and is fixedly connected to the positioning element 520.

[0057] The clamping spring 540 includes a long swing arm 5401 and a short swing arm 5402. The long swing arm 5401 and the short swing arm 5402 are elastic. The first end of the long swing arm 5401 is fixedly connected to the first end of the central shaft 510. The middle part of the long swing arm 5401 near its second end is fixedly connected to the first end of the short swing arm 5402. The second end of the long swing arm 5401 extends outward relative to the short swing arm 5402 to form a pawl 5403. The second end of the short swing arm 5402 is fixed near the first mounting hole 220 of the long side 200.

[0058] Preferably, a second spring 530 is provided between the positioning member 520 and the end face of the short side 300, and the second spring 530 is mounted on the central shaft 510.

[0059] Preferably, the long side 200 facing the clamping spring 540 is provided with annular anti-slip teeth 230 coaxial with the first mounting hole 220, which can increase the friction between the pipe clamp and the surface of the fixing member 600, prevent the pipe clamp from rotating, and ensure the accuracy of the pipeline installation angle.

[0060] When assembling the pipe clamp onto the fixing member 600, simply align the clamping mechanism with the mounting hole on the fixing member 600 and insert it. As the clamping mechanism descends, the long swing arm 5401 of the clamping spring, constrained by the mounting hole, drives the short swing arm 5402 to move closer to the surface of the central shaft 510. The pawl 5403 retracts, and the short swing arm 5402, pushed by the long swing arm 5401, drives the long side 200 to move closer to the positioning member 520, and the second spring 530 is compressed.

[0061] When the chuck 5403 descends below the lower surface of the fixing member 600, the chuck 5403 is no longer restrained by the mounting hole. Under the combined force of the clamping spring 540 and the second spring 530, the positioning member 520 moves away from the second mounting hole 320 on the short side 300, the first end of the central shaft 510 moves away from the first mounting hole 220 on the long side 200, the long swing arm 5401 and the short swing arm 5402 move away from the central shaft 510, and the chuck 5403 opens and engages around the mounting hole on the lower surface of the fixing member 600. The pipe clamp is then secured to the fixing member 600. Figure 16 and 17 As shown.

[0062] When removing the pipe clamp from the fixing member 600, the positioning member 520 needs to be pressed. At this time, the first end of the central shaft 510 moves away from the first mounting hole 220 of the long side 200. As the first end of the long swing arm 5401 moves away from the first mounting hole 220 of the central shaft 510, the first end pulls the short swing arm 5402 closer to the surface of the central shaft 510. The pawl 5403 retracts. At this time, the clamping mechanism can be pulled out from the fixing member 600 and the pipe clamp can be removed.

[0063] The clamping mechanism enables quick installation of pipe clamps on fixtures, and the design of the claws makes the fixation more reliable, saving the time and cost of installing ordinary pipe clamps with bolts and nuts. At the same time, it is easy to disassemble and can be disassembled and assembled multiple times.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
