Description

Technical Field

[0001] The utility model relates to the field of clamping devices, in particular to a pipe seat clamping device. Background Art

[0002] Clamping and securing pipe sockets is a common and critical operation in the assembly and maintenance of numerous industrial equipment, mechanical structures, and everyday items. For example, in the manufacture and maintenance of vehicles like bicycles and motorcycles, pipe sockets and fittings are connected to handlebars and frames. In furniture manufacturing, the metal frames of tables and chairs also require clamping and securing pipe sockets. In industrial machinery, pipe system brackets and pipe sockets are connected, and the frameworks of various mechanical equipment are constructed in such scenarios that require pipe socket clamping.

[0003] Traditional pipe socket clamping methods vary, but all have limitations. Some methods employ direct bolt and nut fastening, while providing a secure connection, require repeated tightening with tools like wrenches during installation and removal, which is time-consuming and labor-intensive. This is particularly inefficient when frequent adjustments to the pipe socket position are required. Furthermore, bolts and nuts can become loose over time due to factors like vibration, compromising connection reliability and necessitating regular inspection and tightening.

[0004] In addition, some more complex clamping devices have complicated structural designs and contain a large number of parts. This not only increases manufacturing costs, but also increases the size and weight of the device, making it difficult to install and use in some applications with limited space. Furthermore, the complex structure leads to a high failure rate and makes repair and maintenance more difficult. Once a component fails, it may need to be completely disassembled and replaced, further increasing the cost and time of use.

[0005] In summary, the existing tube socket clamping device is difficult to meet the demand for efficient, convenient, reliable and low-cost tube socket clamping in modern industrial production and daily life. Therefore, the development of a new type of tube socket clamping device has important practical significance. Utility Model Content

[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] like Figs. 1-3 As shown, a pipe socket clamping device includes a handle 1 and a quick-release clamp 8. The quick-release clamp 8 has a pipe hole 11 at its center for the pipe rod to pass through, a notch 10 is provided in its circumferential direction, and locking wings 9 are connected to both sides of the notch 10. The two connecting arms of the handle 1 are respectively connected to symmetrically distributed protrusions 3. Two sets of locking wings 9 are arranged between the two sets of protrusions 3 and connected by a shaft 4.

[0026] A bushing 5 is provided between the protrusion 3 and the locking wing 9 and is sleeved on the outside of the shaft rod 4. The end surface of the bushing 5 is provided with an inclined surface 6, and a pin 7 is provided in the inclined surface 6 to be plugged into the shaft rod 4.

[0027] The handle 1 is configured to be able to be rotated along the axial direction of the tube hole 11 to a locking position and a release position. When the handle 1 is rotated and pulled to the locking position, the handle 1 drives the pin 7 to rotate through the shaft 4. When the pin 7 is tangent to the inclined surface 6 and away from the inner end of the locking wing 9, the torsional clearance is minimized, and the quick-release harness 8 is in a locked state. When the handle 1 is rotated and pulled to the release position, the handle 1 drives the pin 7 to rotate through the shaft 4. When the pin 7 is tangent to the inclined surface 6 and close to the inner end of the locking wing 9, the torsional clearance becomes maximum, and the quick-release harness 8 is in a released state.

[0028] The outer surface of the handle 1 is connected to a gripping portion 2 , which is provided with an anti-slip protrusion structure.

[0029] This setup has the following advantages:

[0030] Enhanced grip stability

[0031] When using the handle 1 for operations such as playing games or controlling some devices, the hands tend to sweat, and the smooth surface can cause the handle 1 to easily slip out of the hands. The anti-slip protruding structure can increase the friction between the hands and the handle grip 2, allowing the user to hold the handle 1 more stably, reducing the risk of accidental slipping of the handle 1 even in the case of long-time operation or hand sweating, and ensuring the continuity and accuracy of the operation.

[0032] Enhance operation comfort

[0033] The anti-slip protrusions can provide a certain massage effect on the palms and fingers. During the gripping process, the protrusions come into contact with the hands, which can alleviate the fatigue of the hands caused by long-time forceful gripping to a certain extent compared to a completely flat surface, making the user feel more comfortable when operating the handle 1, so as to be more focused on the operation itself.

[0034] The shaft stick 4 is positioned and connected with the handle 1 through the fastener 12.

[0035] This arrangement has the following advantages:

[0036] Stable and reliable connection

[0037] The fastener 12 can provide sufficient fastening force to ensure that the connection between the shaft stick 4 and the handle 1 is tight and stable, and there will be no loosening, shaking or displacement during use, thereby ensuring the structural stability and safety of the entire device, especially in some devices that need to withstand large external forces or frequent movements. This stable connection is particularly important.

[0038] Convenient installation and disassembly

[0039] Compared with other complex connection methods, using the fastener 12 for connection is usually more convenient to operate. When installing, you only need to align the shaft stick 4 with the installation position on the handle 1, and then fix it through the fastener 12. No special tools and complex processes are required, reducing the installation difficulty and cost. At the same time, when the device needs to be repaired, maintained or replaced parts, the connection between the shaft stick 4 and the handle 1 can also be easily disassembled, improving the maintenance efficiency.

[0040] The bushing 5 is movably connected with the corresponding locking wing edge 9.

[0041] This arrangement has the following advantages:

[0042] Convenient installation and disassembly

[0043] The active clamping method generally does not require complex tools and cumbersome operation process. When installing, the bushing 5 is only needed to be aligned with the clamping position of the locking wing edge 9, and then pushed or clamped in to complete the installation, which greatly improves the assembly efficiency. Similarly, when the bushing 5 needs to be disassembled, it can also be easily taken out of the locking wing edge 9, which is convenient for equipment maintenance, maintenance or replacement of the bushing and other operations.

[0044] Reliable and stable connection

[0045] When the bushing 5 is correctly clamped with the locking wing edge 9, a relatively stable connection structure can be formed, which facilitates the pressing of the bushing 5 to the locking wing edge 9. During normal operation of the equipment, even if subjected to certain external force impact, vibration or other interference, it is not easy to appear loose, fall off and other situations, which ensures the position of the bushing 5 in the equipment fixed, thereby ensuring the normal operation and safety of the equipment.

[0046] The quick release clamp 8 is integrally made with the locking wing edge 9.

[0047] This setting has the following advantages:

[0048] High structural strength

[0049] The integrally made structure eliminates the connection gap and weak link between the quick release clamp 8 and the locking wing edge 9, and the overall structure is more compact and firm, which can withstand greater external force and pressure, and is not easy to appear fracture, deformation and other situations during use, thereby improving the reliability and durability of the entire component, and ensuring the stable performance of the equipment in long-term operation.

[0050] High manufacturing precision

[0051] The integrally formed process can better control the dimensional accuracy and geometric tolerance of the quick release clamp 8 and the locking wing edge 9, reduce the cumulative error that may be caused by separate manufacturing and reassembly, make the cooperation between the two more compact and accurate, improve the assembly precision and working efficiency of the entire component, and effectively avoid the problems of jamming and loosening caused by insufficient manufacturing precision.

[0052] Working principle:

[0053] Structural basis

[0054] The center of the quick release clamp 8 has a pipe hole 11 for the pipe rod to pass through, and the notch 10 on the circumference and the locking wing edge 9 on both sides provide a basic structure for clamping action. The protrusion 3 on the connecting arm of the handle 1 is connected with the locking wing edge 9 through the shaft stick 4, forming a movable connection structure, so that the rotation of the handle 1 can be transmitted to the locking wing edge 9 of the quick release clamp 8.

[0055] The bush 5 is sleeved outside the shaft stick 4, and the inclined surface 6 of the end surface and the pin shaft 7 inserted with the shaft stick 4 are key structures for realizing the clamping and releasing functions.

[0056] Clamping process

[0057] When the handle 1 is rotated and pulled along the axial direction of the pipe hole 11 to the locking position, the handle 1 drives the pin shaft 7 to rotate together through the shaft stick 4.

[0058] Since the pin shaft 7 is in the inclined surface 6 of the bush 5, when the pin shaft 7 is tangent to the inner end of the inclined surface 6 away from the locking wing edge 9, according to the geometric relationship, a force that makes the two groups of locking wing edges 9 close to each other is generated at this time.

[0059] The two groups of locking wing edges 9 gradually close to each other under the action of the force, and the gap 10 becomes smaller, so as to tightly hold the pipe rod, and realize the clamping of the pipe rod, and the quick release clamp 8 is in the locking state.

[0060] Releasing process

[0061] When the handle 1 is rotated and pulled to the releasing position, the handle 1 drives the pin shaft 7 to rotate through the shaft stick 4.

[0062] When the pin shaft 7 is tangent to the inner end of the inclined surface 6 close to the locking wing edge 9, the force that makes the two groups of locking wing edges 9 close to each other disappears, so that the torsional gap between the two groups of locking wing edges 9 becomes larger.

[0063] The two groups of locking wing edges 9 are away from each other under the action of the elasticity and structure, the gap 10 becomes larger, and the pipe rod is no longer tightly held, so as to realize the releasing of the pipe rod, and the quick release clamp 8 is in the releasing state.

[0064] The pipe seat clamping device realizes the quick clamping and releasing of the pipe rod through the rotation and pulling of the handle 1, controls the opening and closing of the locking wing edge 9 by using the tangent relationship between the inclined surface 6 of the bush 5 and the pin shaft 7, and has the advantages of simple structure and convenient operation.
