Description

Technical Field

[0001] This application belongs to the field of management card technology, and in particular relates to a management card component. Background Technology

[0002] Pipe clamps are fastening devices used to fix the position of pipes or fittings. They are mainly used for fixing water pipes, gas pipes, and metal pipes. Two pipe clamps of the same shape (upper pipe clamp and lower pipe clamp) are clamped tightly on the pipe, and the pipe clamps are fixed together with bolts to tighten the pipe.

[0003] Patent CN111156350A discloses a pipe clamp and a pipe clamp assembly. The pipe clamp includes a first coupling section and a second coupling section, which are used to fix the pipe fittings end to end together. One end of the first coupling section and one end of the second coupling section are respectively engaged with each other, and the other end of the first coupling section and the other end of the second coupling section are screwed together. The pipe clamp assembly includes a sealing element adapted to the pipe clamp.

[0004] The aforementioned patent addresses the problem of easy pin detachment in existing single-bolt quick-connect pipe clamps by employing a connection method with one end using a snap-fit ​​and the other end using a screw connection. However, in actual use, its single fastening method still has the problem of easy loosening and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a pipe clamp component that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a pipe clamp component, including:

[0007] Mounting base;

[0008] The first arc-shaped component is mounted on the mounting base;

[0009] The second arc-shaped component is disposed on the first arc-shaped component, and one end of it is hinged to the first arc-shaped component;

[0010] A double locking mechanism is used to fix the first and second arc-shaped parts after they are closed;

[0011] The mounting base and the first arc-shaped component are rotatably connected.

[0012] Using the aforementioned pipe clamp assembly, the mounting base serves as the supporting foundation for the entire assembly, allowing the pipe clamp assembly to be fixed in the desired position. A first arc-shaped component is mounted on the mounting base, its shape matching a portion of the pipe to be clamped, and its position is fixed. A second arc-shaped component is mounted on the first arc-shaped component, its shape also matching a portion of the pipe to be clamped. One end of the second arc-shaped component is hinged to the first arc-shaped component, allowing the second arc-shaped component to rotate relative to the first arc-shaped component, thereby clamping or releasing the pipe. By incorporating a double locking mechanism, when the first and second arc-shaped components close and clamp the pipe, the double locking mechanism securely fixes them together, preventing loosening due to vibration or other external factors. The double locking provides additional safety, significantly improving the stability and reliability of the pipe clamp assembly.

[0013] The dual locking mechanism effectively solves the problem of easy loosening in existing fastening methods, making the pipe clamp assembly more stable and reliable after clamping the pipe. It ensures that the pipe will not fall off or loosen due to vibration or other factors during clamping, thereby improving the safety of the entire system.

[0014] Furthermore, the dual locking mechanism includes:

[0015] The internal fixing structure includes a first protrusion disposed on a first arc-shaped member, a second protrusion disposed on a second arc-shaped member, and a fastener connecting the first protrusion and the second protrusion;

[0016] The external fixing structure includes a fixing component disposed on the first arc-shaped member and a snap-fit ​​component disposed on the second arc-shaped member and adapted to the fixing component;

[0017] The first protrusion is located inside the fixing component, and the snap-in component is located outside the second protrusion.

[0018] A first protrusion is mounted on a first arc-shaped component, and a second protrusion is mounted on a second arc-shaped component. The two protrusions form an effective connection point when the arc-shaped components are closed. Fasteners, such as bolts or screws, are used to connect the first and second protrusions and enhance the internal stability of the pipe clamp assembly. A fixing component is mounted on the first arc-shaped component, and a snap-fit ​​component is mounted on the second arc-shaped component. When the first and second arc-shaped components are closed, the snap-fit ​​component and the fixing component cooperate to form an additional locking point.

[0019] The first protrusion is located inside the fixing component, and part of the fixing structure is surrounded by the outer fixing structure. This not only enhances the locking effect but also makes the entire pipe clamp assembly more compact and stable. The snap-in component is located outside the second protrusion, spatially separating the outer and inner fixing structures and preventing mutual interference. The dual locking mechanism in this invention provides additional safety through the combined action of the inner and outer fixing structures, ensuring the stability and reliability of the pipe clamp assembly after clamping the pipe.

[0020] Furthermore: the fixing component includes:

[0021] A support plate, one end of which is connected to the first arc-shaped component, and the other end extends outward;

[0022] An extension plate, one end of which is connected to a support plate, and the other end of which is provided with a barb;

[0023] The extension plate and the support plate are perpendicular to each other, and a fixed space is formed between the extension plate, the support plate and the first protrusion for the insertion of the component.

[0024] One end of the support plate connects to the first arc-shaped component, serving as the basic structure of the fixing assembly to ensure that the entire fixing assembly can be securely installed on the first arc-shaped component. One end of the extension plate connects to the support plate, and the other end is equipped with a barb. The extension plate and the support plate are perpendicular to each other, allowing the extension plate to form an outward barrier, effectively preventing the locking component from uncontrollably detaching from the fixing space. At the same time, the barb design increases the friction between the locking component and the extension plate, further improving the locking effect.

[0025] The extension plate, support plate, and first protrusion together form a fixed space for the snap-in component to enter. The size and shape of this space match the snap-in component to ensure smooth insertion and fixation within it. When the second arc-shaped member closes towards the first arc-shaped member, the user can guide the snap-in component into the fixed space. Due to the elasticity of the extension plate, it can slightly deform upon insertion to accommodate the shape and size of the snap-in component. Once the snap-in component is fully inserted into the fixed space, the extension plate returns to its original shape, firmly securing the snap-in component within the space.

[0026] If it is necessary to release the pipe clamp assembly, the clamping component can be disengaged from the fixed space by prying the extension plate outward. The extension plate can deform under external force, allowing the clamping component to slide out of the fixed space, making the opening and closing of the pipe clamp assembly simple and convenient. By utilizing the elasticity and barbed design of the extension plate, the fixing assembly can effectively prevent the clamping component from accidentally disengaging, thereby ensuring the safety and stability of the entire pipe clamp assembly.

[0027] Furthermore, the snap-in component includes:

[0028] A connecting plate, one end of which is hinged to the second arc-shaped component;

[0029] The elastic plate has one end connected to the end of the connecting plate away from the second arc-shaped part, and the other end is provided with a hook.

[0030] Among them, the hook and the barb are compatible, and the elastic plate can penetrate into the fixed space and make the hook and the barb cooperate.

[0031] One end of the connecting plate is hinged to the second arc-shaped component, serving as the connection point between the locking assembly and the second arc-shaped component. This allows the locking assembly to rotate at a certain angle relative to the second arc-shaped component, facilitating installation and removal from the fixed assembly. One end of the elastic plate is connected to the end of the connecting plate furthest from the second arc-shaped component, while the other end is equipped with a hook. The elastic plate possesses a certain degree of elasticity and toughness, allowing it to deform under external force and return to its original shape after the force is removed, thus ensuring a secure fit between the hook and the barb.

[0032] After the second arc-shaped component closes towards the first arc-shaped component, the user completes the fixation of the internal structure and then fixes the external structure. This is done by rotating the elastic plate and gradually inserting it into the fixation space until the hook and barb meet. Because the elastic plate has a certain degree of elasticity, it can deform slightly when the hook and barb come into contact to accommodate the slight differences between them. Once the hook has completely passed the barb, the elastic plate returns to its original shape, firmly hooking the hook onto the barb, thus achieving a secure fit between the locking component and the fixing component.

[0033] It ensures the overall fastening effect through a double locking structure, and also ensures the overall installation and disassembly efficiency through a quick fixing method using an external fixing structure.

[0034] Furthermore, the barbs are provided in multiple quantities, and the multiple barbs are evenly distributed on the extension plate.

[0035] The barbs create a tight contact with the latch, increasing friction and preventing the clamping assembly from uncontrollably detaching from the fixed space. To enhance the stability and reliability of the pipe clamping assembly, multiple barbs are incorporated into the extension plate to ensure its secure hold within the fixed space. The mating positions can be adjusted to meet different tightening requirements, ensuring the stability and balance of the clamping assembly within the fixed space.

[0036] Furthermore, a rotating plate is hinged to the mounting base, a frustum is provided on the rotating plate, a rotating rod extending into the frustum is provided at the bottom of the first arc-shaped component, and multiple mounting holes are provided on the mounting base.

[0037] The rotating plate is hinged to the mounting base, allowing it to rotate at a certain angle relative to the mounting base, thus providing flexibility in installation angle. A frustum is mounted on the rotating plate to engage with the rotating rod on the first arc-shaped component, providing not only a support point for rotation but also ensuring smooth and reliable rotation. Adjustments to the angle of the first arc-shaped component can be made by rotating the rotating plate. Because the rotating plate and mounting base are hinged, and the first arc-shaped component engages with the frustum via the rotating rod, the angle of the first arc-shaped component relative to the mounting base can be easily adjusted, allowing the pipe clamp assembly to adapt to different pipe layouts and installation requirements.

[0038] The mounting base also has multiple mounting holes, providing more installation options and allowing the pipe clamp assembly to be fixed more flexibly in different positions and angles.

[0039] The beneficial effects of this application are:

[0040] 1. The double locking design provides additional safety protection, significantly improves the stability and reliability of the pipe clamp assembly, and effectively solves the problem of easy loosening of the fastening method in the existing technology, making the pipe clamp assembly more stable and reliable after clamping the pipe;

[0041] 2. The extension plate and support plate are perpendicular to each other, allowing the extension plate to form an outward barrier, effectively preventing the locking component from uncontrollably detaching from the fixed space. Simultaneously, the barb design increases the friction between the locking component and the extension plate, further improving the locking effect.

[0042] 3. The rotating plate is connected to the mounting base via a hinge, allowing the rotating plate to rotate at a certain angle relative to the mounting base, thus providing flexibility in the installation angle. A frustum is mounted on the rotating plate to cooperate with the rotating rod on the first arc-shaped component, providing not only a support point for rotation but also ensuring the smoothness and reliability of the rotation.

[0048] The pipe clamp component provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0049] Example 1:

[0050] like Figure 1 and Figure 2 As shown, this application embodiment provides a pipe clamp component, including:

[0051] Mounting base 100;

[0052] The first arc-shaped component 200 is disposed on the mounting base 100;

[0053] The second arc-shaped component 300 is disposed on the first arc-shaped component 200, and one end of it is hinged to the first arc-shaped component 200;

[0054] A double locking mechanism is used to fix the first arc-shaped member 200 and the second arc-shaped member 300 after they are closed;

[0055] The mounting base 100 and the first arc-shaped component 200 are rotatably connected.

[0056] In some embodiments of this application, such as Figure 1 As shown, using the aforementioned pipe clamp assembly, the mounting base 100 serves as the supporting foundation for the entire pipe clamp assembly, allowing the assembly to be fixed in the desired position. A first arc-shaped member 200 is mounted on the mounting base 100, its shape matching a portion of the pipe to be clamped, and its position is fixed. A second arc-shaped member 300 is mounted on the first arc-shaped member 200, its shape also matching a portion of the pipe to be clamped. One end of the second arc-shaped member 300 is hinged to the first arc-shaped member 200, allowing the second arc-shaped member 300 to rotate relative to the first arc-shaped member 200, thereby clamping or releasing the pipe. By providing a double locking mechanism, when the first arc-shaped member 200 and the second arc-shaped member 300 close and clamp the pipe, the double locking mechanism securely fixes them together, preventing loosening due to vibration or other external factors. The double locking provides additional safety, significantly improving the stability and reliability of the pipe clamp assembly.

[0057] The dual locking mechanism effectively solves the problem of easy loosening in existing fastening methods, making the pipe clamp assembly more stable and reliable after clamping the pipe. It ensures that the pipe will not fall off or loosen due to vibration or other factors during clamping, thereby improving the safety of the entire system.

[0058] In addition, a rotating plate 110 is hinged to the mounting base 100, a frustum 120 is provided on the rotating plate 110, a rotating rod 130 extending into the frustum 120 is provided at the bottom of the first arc-shaped member 200, and a plurality of mounting holes 140 are provided on the mounting base 100.

[0059] The rotating plate 110 is hinged to the mounting base 100, allowing it to rotate at a certain angle relative to the mounting base 100, thus providing flexibility in installation angle. A frustum 120 is mounted on the rotating plate 110 to engage with the rotating rod 130 on the first arc-shaped member 200, providing not only a support point for rotation but also ensuring smooth and reliable rotation. Adjustments to the angle of the first arc-shaped member 200 can be made by rotating the rotating plate 110. Because the rotating plate 110 and the mounting base 100 are hinged, and the first arc-shaped member 200 engages with the frustum 120 via the rotating rod 130, the angle of the first arc-shaped member 200 relative to the mounting base 100 can be easily adjusted, allowing the pipe clamp assembly to adapt to different pipe layouts and installation requirements.

[0060] The mounting base 100 also has multiple mounting holes 140, which provides more installation options and allows the pipe clamp assembly to be fixed more flexibly in different positions and angles.

[0061] Example 2:

[0062] This application provides a pipe clamp component, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0063] like Figure 1 and Figure 2 As shown, the double locking mechanism includes:

[0064] The internal fixing structure 400 includes a first protrusion 410 disposed on the first arc-shaped member 200, a second protrusion 420 disposed on the second arc-shaped member 300, and a fastener 430 connecting the first protrusion 410 and the second protrusion 420.

[0065] The external fixing structure includes a fixing component 500 disposed on the first arc-shaped member 200 and a snap-fit ​​component 600 disposed on the second arc-shaped member 300 and adapted to the fixing component 500;

[0066] The first protrusion 410 is located inside the fixing component 500, and the snap-in component 600 is located outside the second protrusion 420.

[0067] In this embodiment, the first protrusion 410 is mounted on the first arc-shaped member 200, and the second protrusion 420 is mounted on the second arc-shaped member 300. The two protrusions form an effective connection point when the arc-shaped members are closed. A fastener 430, which can be a bolt or screw, is used to connect the first protrusion 410 and the second protrusion 420, and enhances the internal stability of the pipe clamp assembly. A fixing component 500 is mounted on the first arc-shaped member 200, and a locking component 600 is mounted on the second arc-shaped member 300. When the first arc-shaped member 200 and the second arc-shaped member 300 are closed, the locking component 600 and the fixing component 500 cooperate to form an additional locking point.

[0068] The first protrusion 410 is located inside the fixing component 500, and part of the fixing structure is surrounded by the outer fixing structure, which not only enhances the locking effect but also makes the entire pipe clamp assembly more compact and stable. The snap-in component 600 is located outside the second protrusion 420, which spatially separates the outer fixing structure from the inner fixing structure 400, avoiding mutual interference. The dual locking mechanism in this invention provides additional safety protection through the combined action of the inner fixing structure 400 and the outer fixing structure, ensuring the stability and reliability of the pipe clamp assembly after clamping the pipe.

[0069] Example 3:

[0070] This application provides a pipe clamp component, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0071] like Figure 1 and Figure 2 As shown, the fixing component 500 includes:

[0072] The support plate 510 has one end connected to the first arc-shaped member 200 and the other end extending outward;

[0073] An extension plate 520 is connected at one end to a support plate 510 and at the other end is provided with a barb 521;

[0074] The extension plate 520 and the support plate 510 are perpendicular to each other, and a fixed space 530 for the insertion component 600 to enter is formed between the extension plate 520, the support plate 510 and the first protrusion 410.

[0075] One end of the support plate 510 is connected to the first arc-shaped member 200, serving as the basic structure of the fixing component 500 to ensure that the entire fixing component 500 can be securely installed on the first arc-shaped member 200. One end of the extension plate 520 is connected to the support plate 510, and the other end is provided with a barb 521. The extension plate 520 is perpendicular to the support plate 510, allowing the extension plate 520 to form an outward barrier, effectively preventing the locking component 600 from uncontrollably detaching from the fixing space 530. At the same time, the design of the barb 521 increases the friction between the locking component 600 and the extension plate 520, further improving the locking effect.

[0076] In this embodiment, the extension plate 520, the support plate 510, and the first protrusion 410 together form a fixed space 530 for the insertion component 600 to enter. The size and shape of this space match the insertion component 600 to ensure that the insertion component 600 can be smoothly inserted and fixed in the fixed space 530. When the second arc-shaped member 300 closes to the first arc-shaped member 200, the user can guide the insertion component 600 into the fixed space 530. Because the extension plate 520 has a certain degree of elasticity, it can undergo slight deformation when the insertion component 600 enters to adapt to the shape and size of the insertion component 600. Once the insertion component 600 is fully inserted into the fixed space 530, the extension plate 520 will return to its original shape, firmly fixing the insertion component 600 in the fixed space 530.

[0077] If it is necessary to release the pipe clamp assembly, the locking component 600 can be disengaged from the fixed space 530 by prying the extension plate 520 outward. The extension plate 520 can deform under external force, allowing the locking component 600 to slide out of the fixed space 530, making the opening and closing operation of the pipe clamp assembly simple and convenient. By utilizing the elasticity of the extension plate 520 and the design of the barb 521, the fixing component 500 can effectively prevent the locking component 600 from accidentally disengaging, thereby ensuring the safety and stability of the entire pipe clamp assembly.

[0078] Example 4:

[0079] This application provides a pipe clamp component, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0080] like Figure 1 and Figure 2 As shown, the snap-in component 600 includes:

[0081] The connecting plate 610 has one end hinged to the second arc-shaped piece 300;

[0082] The elastic plate 620 has one end connected to the end of the connecting plate 610 away from the second arc-shaped member 300, and the other end is provided with a hook 630.

[0083] Among them, the hook 630 is adapted to the barb 521, and the elastic plate 620 can penetrate into the fixing space 530 and make the hook 630 cooperate with the barb 521.

[0084] In this embodiment, one end of the connecting plate 610 is hinged to the second arc-shaped member 300, serving as the connection point between the snap-fit ​​component 600 and the second arc-shaped member 300. This allows the snap-fit ​​component 600 to rotate at a certain angle relative to the second arc-shaped member 300, facilitating installation and removal from the fixing component 500. One end of the elastic plate 620 is connected to the end of the connecting plate 610 away from the second arc-shaped member 300, and the other end is provided with a hook 630. The elastic plate 620 has a certain degree of elasticity and toughness, enabling it to deform under external force and return to its original shape after the external force disappears, thereby ensuring a firm fit between the hook 630 and the barb 521.

[0085] After the second arc-shaped component 300 closes to the first arc-shaped component 200, the user completes the fixation of the internal fixing structure 400, and then fixes the external fixing structure. This is done by rotating the elastic plate 620 and gradually inserting it into the fixing space 530 until the hook 630 meets the barb 521. Because the elastic plate 620 has a certain degree of elasticity, it can undergo slight deformation when the hook 630 contacts the barb 521 to accommodate the slight difference between them. Once the hook 630 has completely passed the barb 521, the elastic plate 620 returns to its original shape, tightly hooking the hook 630 onto the barb 521, thus achieving a secure fit between the engaging component 600 and the fixing component 500.

[0086] It ensures the overall fastening effect through a double locking structure, and also ensures the overall installation and disassembly efficiency through a quick fixing method using an external fixing structure.

[0087] Furthermore, multiple barbs 521 are provided, and the multiple barbs 521 are evenly distributed on the extension plate 520.

[0088] In some embodiments of this application, the barb 521 can form a tight contact with the hook 630, thereby increasing the friction between the two and preventing the locking component 600 from uncontrollably detaching from the fixed space 530. To improve the stability and reliability of the pipe clamp assembly, multiple barbs 521 are provided on the extension plate 520 to ensure the secure positioning of the locking component 600 in the fixed space 530. The mating position can be adjusted according to different fastening requirements. This ensures the stability and balance of the locking component 600 in the fixed space 530.
