Description

Technical Field

[0001] This utility model relates to the technical field of pipeline and wire harness fastening devices, and more specifically, to a pipe clamp device. Background Technology

[0002] Pipe clamps, as core tools for securing pipes and wire harnesses, are widely used in fixing motherboard cables inside electronic devices, organizing automotive wiring harnesses, arranging hydraulic pipelines in industrial machinery, and building electrical wiring. They are key components ensuring the orderly installation and stable operation of various pipeline systems. Most existing pipe clamps employ a toothed locking structure. Specifically, raised teeth matching the toothed grooves of a rack are pre-set on the inner wall of the insertion hole of the locking seat. During assembly, the rack is inserted axially along the insertion hole, squeezing the edge of the insertion opening to induce elastic deformation for smooth sliding. After the rack pushes the pipe clamp body to the preset limit position, the teeth inside the insertion hole and the toothed grooves on the rack surface form a hook-and-grip engagement, thereby securing the pipe or wire harness and preventing it from loosening naturally.

[0003] However, this structure has obvious defects: First, because the insertion area of ​​the socket needs to reserve space for elastic deformation, the material is usually designed to be relatively soft, which makes it easy for the rack to be pushed outward after insertion. Especially under accidental pulling force or vibration, the risk of the rack being forcibly pulled out increases significantly, directly destroying the fastening effect. Second, when the object being fastened inside the clamp expands outward unevenly, it will generate asymmetrical extrusion force on the inner wall of the locking seat, which can easily cause the teeth in the socket to warp and spring open, resulting in a decrease in the biting depth between the teeth and the rack. This not only greatly reduces the locking force, but in severe cases, it can also directly lead to unlocking failure and cause pipeline detachment accidents. Utility Model Content

[0004] This application mainly addresses the technical problems of poor locking reliability, weak vibration resistance, and insufficient resistance to uneven expansion of the fastened object in existing pipe clamp devices, which easily lead to rack dislodgement or unlocking failure. In order to overcome the above-mentioned defects of the prior art, this application provides a pipe clamp device.

[0005] This application provides a pipe clamp device, comprising: The pipe clamp body has a receiving space for accommodating the object to be fastened; The locking band has one end connected to the main body of the pipe clamp via a folding part, and the other end is provided with a toothed rack; A locking seat is fixed to the main body of the pipe clamp and has an insertion hole for inserting the rack; An elastic cantilever beam has one end fixed to a locking seat and the other end provided with at least one tooth. Under the elastic force of the elastic cantilever beam, the tooth shifts toward the pipe clamp body. The extension direction of the elastic cantilever beam is the same as the direction in which the rack is inserted into the insertion hole. When the rack is inserted into the insertion hole, the grooves and teeth of the rack engage to prevent the rack from retracting.

[0006] Compared with existing technologies, the pipe clamp device proposed in this application has the following advantages: The elastic cantilever beam, driven by its own elasticity, causes the teeth to shift towards the clamp body, and its extension direction is consistent with the insertion direction of the rack. The teeth are located at the end of the elastic cantilever beam away from the locking seat. After the rack is inserted into the socket, the teeth tightly engage with the rack's tooth groove, meaning the teeth are separated from the socket. Compared with the existing technology's structure where "the socket insertion material is too soft and easily pried open," this significantly improves the constraint force of the teeth on the rack, reduces the risk of the rack being forcibly pulled out under accidental pulling or vibration, and ensures stable fastening effect. When the fastened object expands unevenly outward, the elasticity of the cantilever beam can maintain the engagement depth between the teeth and the rack, avoiding the problem of "teeth in the socket easily warping and springing open" in existing technologies, preventing a decrease in locking force or direct unlocking failure, and reducing pipeline detachment accidents.

[0007] In one possible implementation, the number of teeth is multiple, and they are arranged sequentially along the extension direction of the elastic cantilever beam. Compared with the prior art, multiple teeth arranged along the extension direction of the elastic cantilever beam can form multiple sets of interlocking engagements with the rack. Compared with a single-tooth structure, there are more interlocking contact points and the force is more evenly distributed, which can significantly enhance the overall locking force. Even if individual teeth fail due to wear or slight deformation, the remaining teeth can still maintain the engagement, improving the locking reliability.

[0008] In one possible implementation, the locking seat is integrally formed with the pipe clamp body. Compared with the prior art, the locking seat and the pipe clamp body are integrally formed, with no splicing gaps or weak points in the connection, ensuring the positional accuracy and structural strength of the locking structure.

[0009] In one possible implementation, the insertion port of the socket is provided with a beveled guide surface, which guides the rack into the socket. Compared with the prior art, the beveled guide surface can guide the rack into the socket quickly and smoothly without the need for precise alignment of the insertion port, reducing the difficulty of assembly operations and improving assembly efficiency.

[0010] In one possible implementation, the folding portion is an integrally formed folding piece between the locking band and the pipe clamp body. Compared with the prior art, the integrally formed folding piece has a more compact structure and higher connection strength compared with connection methods such as hinges and welding. It can withstand multiple folding operations without easily breaking, preventing the connection between the locking band and the pipe clamp body from loosening or falling off, and ensuring long-term reliability.

[0011] In one possible implementation, the rack and locking band are integrally formed and connected. Compared with the prior art, the rack and locking band are integrally formed without connection gaps, allowing for uniform force transmission under stress and improving the overall load-bearing capacity of the locking band and rack.

[0012] In one possible implementation, a baffle is provided between the rack and the locking band, and the baffle abuts against the insertion opening of the socket. Compared with the prior art, the baffle abutting against the insertion opening of the socket can limit the maximum insertion depth of the rack, avoid improper tooth engagement caused by excessive rack insertion, and ensure the stability of the locking effect.

[0013] In one possible implementation, the elastic cantilever beam and the locking seat are integrally formed and connected. Compared with the prior art, the integral forming of the elastic cantilever beam and the locking seat can prevent the elastic cantilever beam from falling off the locking seat when subjected to force deformation, ensuring that the elastic force is stably transmitted to the teeth and maintaining the offset state of the teeth towards the clamp body.

[0014] In one possible implementation, a weakening groove is provided between the elastic cantilever beam and the locking seat, with the opening of the weakening groove facing away from the main body of the pipe clamp. Compared with the prior art, the weakening groove allows the elastic cantilever beam to deform in this area, avoiding deformation concentration that could lead to fracture and extending the elastic life of the elastic cantilever beam.

[0015] In one possible implementation, a boss is provided on the main body of the clamp near the teeth, the boss being used to prevent foreign objects from hooking the teeth. Compared with the prior art, the boss can physically prevent foreign objects from contacting the teeth, avoiding the teeth from warping or disengaging from the rack, and maintaining a stable locking state.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 5 This application discloses a pipe clamp device, including: a pipe clamp body 1, a locking band 2, a locking seat 3, and an elastic cantilever beam 4.

[0022] The pipe clamp body 1 is injection molded from high-strength engineering plastic. The body has an arc-shaped structure and an internal space 11 for accommodating the object to be fastened (such as pipes or wire harnesses). The size of the space 11 is designed according to the diameter of the object to be fastened. The inner wall can be provided with anti-slip texture or a buffer layer to enhance the fastening effect and prevent damage to the object.

[0023] The locking band 2 is a strip structure made of the same material as the pipe clamp body 1. One end of the locking band 2 is connected to the pipe clamp body 1 through the folding part 5, and the other end extends to form a free end, which is integrally formed with a toothed rack 21.

[0024] The locking seat 3 is fixed to the outside of the pipe clamp body 1 and is connected to the pipe clamp body 1 by integral molding. The locking seat 3 has a rectangular insertion hole 31, the size of which is slightly larger than the size of the rack 21, so as to allow the rack 21 to be inserted smoothly but to avoid excessive wobbling.

[0025] An elastic cantilever beam 4 is mounted on a locking seat 3, with one end fixedly connected to the locking seat 3 and the other end being a free end extending along the direction in which the rack 21 is inserted into the insertion hole 31. The free end of the elastic cantilever beam 4 has two integrally formed teeth 41 (the teeth 41 match the tooth grooves of the rack 21), with the inclined surfaces of the teeth 41 facing the insertion hole 31. In its natural state, the elastic force of the elastic cantilever beam 4 causes the teeth 41 to shift towards the clamp body 1, ensuring that a pre-clamping force is generated when the teeth 41 contact the rack 21. In other embodiments, the elastic cantilever beam 4 has multiple teeth 41, which are arranged at equal intervals along the extension direction of the elastic cantilever beam 4; multiple teeth 41 simultaneously engage with multiple sets of tooth grooves of the rack 21, forming distributed locking points, thereby increasing the locking contact area and load-bearing strength.

[0026] When rack 21 enters insertion hole 31, the grooves of rack 21 contact the teeth 41, compressing the elastic cantilever beam 4 and causing it to elastically deform outward. After rack 21 is fully inserted, elastic cantilever beam 4 rebounds, and teeth 41 engage with the grooves of rack 21, forming a one-way locking fit to prevent rack 21 from retracting. This design significantly improves locking reliability and vibration resistance through the rebound force of elastic cantilever beam 4.

[0027] In this embodiment, a beveled guide surface 311 is provided at the insertion port 31 of the locking seat 3. The beveled guide surface 311 serves as a guiding structure, contacting the end of the rack 21 during the initial insertion phase. Through the guiding action of the beveled surface, it automatically corrects the position and angle of the rack 21, reducing insertion resistance and frictional wear. This is particularly suitable for rapid installation in confined spaces, preventing jamming or damage caused by rack 21 misalignment.

[0028] In this embodiment, the folding portion 5 is an integrally formed folding piece, the thickness of which is slightly less than the thickness at the connection between the locking band 2 and the tube clamp body 1, to provide a flexible hinge function. The folding piece allows the locking band 2 to fold at a large angle relative to the tube clamp body 1, facilitating its wrapping around the object being fastened. This folding piece achieves folding through the elastic deformation of the material itself, eliminating the need for additional hinge parts, simplifying the structure and improving durability.

[0029] In this embodiment, a rectangular plate-shaped baffle 22 is provided at the connection between the rack 21 and the locking band 2. When the rack 21 is inserted into the insertion hole 31 to its limit position, the baffle 22 abuts against the edge of the insertion opening of the insertion hole 31, forming a physical limit. The baffle 22 prevents the rack 21 from being over-inserted, ensures the accurate engagement position of the teeth 41 and the rack 21, and also serves as a secondary safety device to prevent disengagement, enhancing the reliability of the locking mechanism.

[0030] In this embodiment, a weakening groove 42 is provided at the connection root between the elastic cantilever beam 4 and the locking seat 3. The opening direction of the weakening groove 42 is away from the tube clamp body 1 (i.e., facing outward). By locally reducing the material thickness, the weakening groove 42 precisely controls the bending stiffness and elastic deformation range of the elastic cantilever beam 4, making it easier to bend and with uniform rebound force when the rack 21 is inserted, thereby improving the locking smoothness and the meshing accuracy of the teeth 41.

[0031] In this embodiment, two block-shaped protrusions 6 are provided on the clamp body 1 near the corresponding position of the tooth 41. When an external foreign object attempts to hook the tooth 41, the protrusions 6 act as a physical barrier to prevent the foreign object from contacting the tooth 41 and to prevent accidental unlocking.

[0032] The beneficial effects of this application include: I. Significantly Improved Locking Reliability: By setting an elastic cantilever beam 4 whose extension direction is consistent with the insertion direction of the rack 21, and setting teeth 41 at its free end, the elasticity of the cantilever beam ensures that the teeth 41 are always offset towards the clamp body 1, forming a stable engagement with the tooth groove of the rack 21. This structure avoids the problem of the traditional insertion hole 31 being too soft and easily pried open, effectively preventing the rack 21 from disengaging under vibration or accidental pulling, making the locking more reliable.

[0033] 2. Strong resistance to uneven expansion: The elastic cantilever beam 4 has a continuous rebound capability. Even when the fastened object expands unevenly, it can still maintain the biting depth between the teeth 41 and the rack 21, preventing the decrease in locking force or unlocking failure caused by the warping of the teeth 41, and reducing the risk of pipeline detachment.

[0034] III. Structural Optimization and Convenient Assembly: The integrated molding design (such as locking seat 3 and main body, rack 21 and locking band 2, folding part 5, etc.) enhances the overall structural strength and durability; the inlet of the insertion hole 31 is provided with a sloping guide surface 311, which facilitates the quick insertion of rack 21 and improves assembly efficiency; the baffle 22 and the boss 6 respectively play the roles of limiting and preventing foreign object interference, further ensuring the stability of the locking state.
