Description

Technical Field

[0001] This application relates to the technical field of pipe clamps, and in particular to a quick-installation pipe clamp with interlocking ends. Background Technology

[0002] Pipe clamps, as a common mechanical connector, are widely used in the fixing and support of pipeline systems.

[0003] Traditional pipe clamps are typically split-type, consisting of two parts with curved semi-clamps. To secure the pipe, the two semi-clamps must first be snapped together onto the outside of the interlocking pipe. Then, using bolts and nuts, the two semi-clamps are connected and tightened. This method is inconvenient for workers, especially when operating the bolts and nuts to connect the two semi-clamps. Holding the semi-clamps with both hands can cause them to shift or deviate during operation, potentially requiring multiple adjustments and resulting in low pipe securing efficiency. Utility Model Content

[0004] To facilitate the operation of pipe clamps and improve the efficiency of pipe fixing, this application provides a quick-installation pipe clamp with interlocking ends.

[0005] A quick-installation pipe clamp with interlocking ends includes a positioning band and a snap-fit ​​band connected to each other. The positioning band is provided with a positioning strip, which is bent toward the snap-fit ​​band and has a positioning block. The end of the positioning block facing the snap-fit ​​band is pointed. A plurality of positioning teeth are evenly arranged on the outer side wall of the snap-fit ​​band end. A positioning tooth groove is formed between two adjacent positioning teeth to accommodate the pointed part of the positioning block. When the snap-fit ​​band bends toward the positioning band and passes the position of the positioning block and is then released, the pointed part of the positioning block can be inserted into the positioning tooth groove and restrict the snap-fit ​​band from rotating in the opposite direction.

[0006] By adopting the above technical solution, the positioning strip and the snap-fit ​​strip are interconnected, resulting in a stable overall structure. The positioning strip bends towards the snap-fit ​​strip, allowing the positioning block to approach the snap-fit ​​strip. The tip structure of the positioning block facilitates insertion into the positioning tooth groove. The positioning teeth and positioning tooth groove on the outer wall of the snap-fit ​​strip end enable the tip of the positioning block to insert into the positioning tooth groove after the snap-fit ​​strip is bent and released, effectively limiting the reverse rotation of the snap-fit ​​strip. This achieves rapid installation and automatic locking of the pipe clamp without the need for additional bolts, thus simplifying the installation steps and improving the efficiency of pipe fixing.

[0007] Preferably, the opening of the positioning groove is inclined away from the positioning block.

[0008] By adopting the above technical solution, the opening of the positioning tooth groove is inclined away from the positioning block, making it less likely for the tip of the positioning block to fall out of the positioning tooth groove after being inserted into it, thus enhancing the stability of the pipe clamp connection.

[0009] Preferably, a plurality of force-applying blocks are spaced apart on the outer side wall of the snap-fit ​​strap.

[0010] By adopting the above technical solution, several force-applying blocks are set at intervals on the outer wall of the clamping strip, which facilitates the application of force points when operating the pipe clamp, making it easier for operators to apply force to the clamping strip to complete the installation or adjustment of the pipe clamp.

[0011] Preferably, it also includes a control component and a limiting component. A positioning seat is provided on the outer wall of the positioning strip, and the positioning block is rotatably mounted on the positioning seat. The control component can control the positioning block to rotate on the positioning seat, and the limiting component can restrict the rotation of the positioning block. When the positioning block rotates in the direction of the snap-fit ​​tape, the positioning block can drive the snap-fit ​​tape to continue to bend and rotate in the direction of the positioning strip.

[0012] By adopting the above technical solution, the positioning block can be flexibly controlled to rotate on the positioning seat using the control component, thereby driving the snap-fit ​​tape to continue bending and rotating in the direction of the positioning strip, so as to realize the further clamping operation of the pipe clamp; the limiting component can ensure that the positioning block remains stable after rotating into place, thus ensuring the stability of the pipe clamp connection.

[0013] Preferably, the upper end of the positioning seat is rotatably provided with a rotating shaft, which passes through the positioning block and is fixedly connected to the positioning block.

[0014] By adopting the above technical solution, a rotating shaft is rotatably provided at the upper end of the positioning seat. The rotating shaft passes through the positioning block and is fixedly connected to the positioning block, so that the positioning block can rotate around the rotating shaft.

[0015] Preferably, the control component includes a control rod and a connecting rod connected to each other. The length directions of the connecting rod and the control rod are parallel to the length direction of the rotation shaft. The connecting rod is rotatably disposed within the positioning seat. The control rod has a polygonal cross-section, and the outer diameter of the control rod is smaller than the outer diameter of the connecting rod. A control groove is provided at the end of the rotation shaft for the control rod to slide into. One end of the control rod is inserted into the control groove, and the other end of the control rod extends out of the positioning seat. The limiting component can restrict the rotation of the connecting rod.

[0016] By adopting the above technical solution, the structural design of the control component allows operators to achieve precise control of the positioning block through the cooperation of the control rod and the connecting rod. The control rod slides into the control slot on the rotating shaft, ensuring the stability and operability of the connection. At the same time, the polygonal cross-section design of the control rod facilitates the application of torque.

[0017] Preferably, the control component further includes a rotary handle, and one end of the control rod extending out of the positioning seat is connected to the rotary handle.

[0018] By adopting the above technical solution, the addition of the rotating handle makes it easier for operators to apply force to the control rod, thereby effectively controlling the rotation of the positioning block.

[0019] Preferably, the limiting member includes a limiting ring coaxially disposed on the outer wall of the connecting rod and a plurality of limiting teeth circumferentially disposed on the outer wall of the limiting ring. The side wall of the positioning seat is provided with a limiting groove for the limiting ring and the limiting teeth to be inserted. When the limiting ring slides out of the limiting groove, the control rod is still inserted in the control groove.

[0020] By adopting the above technical solution, the setting of the limiting ring and the limiting tooth can effectively limit the rotation of the connecting rod, thereby ensuring that the positioning block remains in the current position; when it is necessary to adjust the bending degree of the snap-fit ​​tape, the limitation on the connecting rod can be released by sliding the limiting ring out of the limiting groove, which is simple and convenient to operate.

[0021] Preferably, the limiting component further includes a spring, and the positioning seat has a receiving groove for installing the spring. One end of the spring is fixed to the bottom wall of the receiving groove, and the other end of the spring is connected to the end face of the limiting ring. The connecting rod slides through the spring. When the end of the limiting ring is inserted into the limiting groove, the spring is in a stretched state.

[0022] By adopting the above technical solution, the spring design provides an automatic reset function. When the end of the limiting ring is inserted into the limiting groove, the spring is in a stretched state. The elastic force generated by the spring keeps the limiting ring in a stable insertion state, effectively preventing accidental rotation of the connecting rod and improving the stability of the pipe clamp when fixing the pipeline. Simultaneously, when it is necessary to release the limiting position, simply overcome the spring force to disengage the limiting ring from the limiting groove. The operation is simple and convenient, improving the flexibility of the pipe clamp.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By engaging the positioning blocks on the positioning strip with the positioning teeth at the end of the snap-fit ​​tape, the pipe clamp can quickly complete the fixing operation of the pipe, simplifying the installation process;

[0025] 2. By rotating and adjusting the positioning block, the clamping effect of the pipe clamp on the pipe can be further adjusted. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a quick-installation pipe clamp with interlocking ends. (Refer to...) Figure 1 The pipe clamp includes a positioning band 1 and a clamping band 2 connected to each other. The positioning band 1 and the clamping band 2 are preferably integrally formed and preferably made of metal, such as stainless steel, which has good strength and toughness. In other embodiments, high-strength plastic material can also be used. A positioning strip 3 is provided on the positioning band 1. The positioning strip 3 can be cut and formed from the positioning band 1, and bent into an arc-shaped strip structure towards the clamping band 2. The clamping band 2 is bent towards the positioning strip 3, working in conjunction with the clamping band 2 to clamp and fix the pipe fitting.

[0032] Furthermore, the positioning strip 3 is provided with a positioning block 4, which extends towards the clamping band 2, and the extended end is preferably designed as a pointed structure. Positioning teeth 21 are evenly distributed on the outer wall of the clamping band 2, and a positioning groove 22 is formed between adjacent positioning teeth 21 to accommodate the pointed portion of the positioning block 4. When the clamping band 2 bends towards the positioning strip 3, it can be inserted into the inner side of the positioning strip 3. After insertion, releasing the hand causes the clamping band 2 to rebound, at which point the positioning block 4 can be inserted into the positioning groove 22, restricting the clamping band 2 from further rotation, thus fixing the pipe clamp to the pipe, completing the connection between the pipe clamp and the pipe. This design avoids the problem of needing to adjust the pipe clamp position multiple times due to the inconvenience of single-person operation in traditional two-piece installation methods, greatly improving the installation speed while also ensuring a certain degree of stability.

[0033] In an optional embodiment, the positioning teeth 21 are preferably designed with a serrated structure, such that the opening of the positioning tooth groove 22 is inclined away from the positioning block 4; each positioning tooth 21 has the same height and width, and the tooth pitch is set according to actual needs. The tip of the positioning tooth 21 is preferably set in an arc shape to increase the contact surface with the positioning block 4 and improve the stability of the positioning block 4 in positioning the rack. This design creates a one-way locking mechanism between the positioning block 4 and the positioning teeth 21, similar to the cooperation of a ratchet and a pawl, which not only fixes the pipe but also prevents the pipe clamp from accidentally loosening.

[0034] Reference Figure 1 In one optional embodiment, a plurality of force-applying blocks 5 are spaced apart on the outer wall of the snap-fit ​​strap 2. The force-applying blocks 5 are protruding structures, preferably shaped like an approximate T-shape to facilitate the application of force. The force-applying blocks 5 are preferably located in the middle of the snap-fit ​​strap 2 to accommodate the force required by the user during the process of controlling the bending of the snap-fit ​​strap 2. The force-applying blocks 5 are made of the same material as the snap-fit ​​strap 2 and can be fixed by welding or other methods.

[0035] Reference Figure 1 and Figure 2 In an optional embodiment, it further includes a control element 7 and a limiting element 8. A positioning seat 6 is fixed to the outer wall of the snap-fit ​​strap 2 by welding or screws, etc. The positioning seat 6 extends in a direction away from the positioning strap 1. The positioning block 4 is rotatably mounted on the positioning seat 6. The control element 7 can control the positioning block 4 to rotate on the positioning seat 6, and the limiting element 8 can restrict the rotation of the positioning block 4. When the positioning block 4 rotates in the direction of the snap-fit ​​strap 2, i.e., referring to... Figure 1 In the aforementioned orientation, when the positioning block 4 rotates clockwise, the portion of the positioning block 4 inserted into the positioning tooth groove 22 can drive the clamping strap 2 to continue bending and rotating towards the positioning seat 6, that is, rotating counterclockwise. This allows the clamping strap 2 to further tighten the pipe, improving the pipe's fixing effect. It should be noted that... Figure 1 The position is for reference only, and the positioning block 4 on it has been rotated clockwise by a certain angle.

[0036] Specifically, the positioning seat 6 has an installation groove for mounting the positioning block 4 at its end away from the positioning band 1; a rotating shaft is rotatably mounted at the end of the positioning seat 6, passing through the positioning block 4 and fixedly connected to it, thereby achieving a rotatable connection of the positioning block 4; both ends of the rotating shaft are rotatably connected to the positioning seat 6 via bearings or other means. The control component 7 includes a control rod 71 and a connecting rod 72 connected to each other. The length directions of the connecting rod 72 and the control rod 71 are parallel to the length direction of the rotating shaft 61. The connecting rod 72 is rotatably mounted inside the positioning seat 6. The cross-section of the connecting rod 72 is circular, and the cross-section of the control rod 71 is polygonal, which is rectangular in this embodiment; at the same time, the outer diameter of the control rod 71 is smaller than the outer diameter of the connecting rod 72. A control groove is provided at the end of the rotating shaft 61 for the control rod 71 to slide into, and the control groove is correspondingly rectangular; one end of the control rod 71 is inserted into the control groove, and the other end of the control rod 71 passes through the positioning seat 6. By rotating the connecting rod 72, the control rod 71 can be rotated, thereby driving the rotating shaft 61 to rotate and the positioning block 4 to rotate via the connecting shaft.

[0037] Furthermore, the control component 7 also includes a rotary handle 73, with one end of the control lever 71 extending out of the positioning seat 6 and connected to the rotary handle 73. The rotary handle 73 is designed to facilitate the operator applying external force; by rotating the rotary handle 73, the control lever 71 can be rotated, thereby facilitating the control of the positioning block 4.

[0038] Reference Figure 2 and Figure 3 The limiting member 8 can restrict the rotation of the connecting rod 72, thereby restricting the rotation of the positioning block 4. Specifically, the limiting member 8 includes a limiting ring 81 coaxially disposed on the outer wall of the connecting rod 72. The outer wall of the limiting ring 81 is provided with a plurality of limiting teeth in the circumferential direction. The side wall of the positioning seat 6 is provided with a limiting groove for the limiting ring 81 and the limiting teeth to be inserted.

[0039] Furthermore, the limiting component 8 also includes a spring 82. A receiving groove for mounting the spring 82 is provided in the positioning seat 6. One end of the spring 82 is fixed to the bottom wall of the receiving groove, and the other end of the spring 82 is connected to the end face of the limiting ring 81. The connecting rod 72 slides through the spring 82. When the end of the limiting ring 81 is inserted into the limiting groove, the spring 82 is in a stretched state, thereby providing a certain preload force to the positioning block 4 to prevent it from accidentally loosening.

[0040] The implementation principle of the quick-installation pipe clamp with interlocking ends in this application embodiment is as follows: When it is necessary to connect pipes, the two pipes are inserted into each other, and then the pipe clamp is placed on the outside of the pipes. At the same time, force is applied by the force block 5 and the positioning band 1, so that the snap-fit ​​band 2 and the positioning strip 3 are brought closer to each other, and the end of the snap-fit ​​band 2 is controlled to pass over the tip of the positioning block 4, and the snap-fit ​​band 2 is inserted into the inside of the positioning strip 3; and the positioning tooth groove 22 on the snap-fit ​​band 2 corresponds to the tip of the positioning block 4. After the snap-fit ​​band 2 is released, the snap-fit ​​band 2 returns to its original position under its own elastic force, and the tip of the positioning block 4 is inserted into the positioning tooth groove 22, and the pipe clamp is initially fixed to the pipe.

[0041] Next, by turning the handle, the limiting ring 81 is controlled to slide out of the limiting groove. Then, by turning the handle 73, the connecting rod 72 is rotated and the positioning block 4 is rotated, which causes the clamping strap 2 to continue to bend and further clamp the pipe. After clamping, the limiting ring 81 is reinserted into the limiting groove. The interface restricts the rotation of the limiting ring 81 and the positioning block 4 through the cooperation of the limiting teeth and the limiting groove, thus completing the fixation of the pipe clamp on the pipe.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
