Description

TECHNICAL FIELD

[0001] The utility model relates to the field of clamping device, concretely relates to a novel pipe base clamping device. BACKGROUND

[0002] In today's industrial production and various engineering practices, the installation and fixing of pipe rods are very common and are widely distributed in many fields such as mechanical manufacturing, pipeline laying, equipment assembly, chemical process and building installation. For example, in mechanical manufacturing, the cooling liquid delivery pipeline of various machine tools and the air pipe connection of pneumatic control systems cannot be separated from the stable support of pipe bases on pipe rods; in pipeline laying engineering, the branch connection parts of urban water supply and drainage pipe networks and natural gas delivery pipelines, the role of pipe bases is even more important, which is directly related to the sealing and running stability of the entire pipe network system.

[0003] The traditional pipe base clamping method has many drawbacks. On the one hand, the operation process is complex and tedious, often requiring the use of various tools such as wrenches and screwdrivers for step-by-step tightening, which not only consumes a lot of manpower and time cost, but also requires high skill proficiency of the operator. For example, in some old mechanical processing equipment oil pipe fixing, workers need to spend a lot of time adjusting the pipe clamp position and tightening the nut every time the oil pipe is replaced or the equipment is maintained, which greatly affects the production efficiency. On the other hand, the clamping effect is not satisfactory, and under the conditions of vibration, fluid impact or temperature change generated during equipment operation, the pipe rod is prone to looseness and displacement, leading to problems such as medium leakage and unstable system pressure, which poses a hidden danger to safety production. In chemical production, if the pipe connection leaks due to loose pipe base clamping, it may cause serious environmental pollution or even explosion accidents. Furthermore, the disassembly process is also inconvenient, and when the pipe rod needs to be replaced or the equipment needs to be maintained, the traditional pipe base structure often makes the disassembly work difficult, increasing the equipment downtime and maintenance cost.

[0004] Therefore, there is an urgent need to develop a convenient, efficient and reliable pipe base clamping device, which can effectively solve the problems of the prior art, improve the overall level of pipe rod installation and maintenance in various industries, and ensure the stable operation of the production system. CONTENT OF THE UTILITY MODEL

[0005] To solve the above problems, especially for the deficiencies of the prior art, the utility model provides a novel pipe base clamping device which can solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical means:

[0007] A novel tube clamping device includes a handle and a quick-release buckle. The quick-release buckle has a tube hole at its center for the tube rod to pass through, and a notch in its circumferential direction. Locking wings are connected to both sides of the notch. The two connecting arms of the handle are respectively connected to symmetrically distributed rotating shafts. The two sets of locking wings are arranged between the two sets of rotating shafts and connected by bushings.

[0008] The bushing is connected to a locking block at the end corresponding to the locking wing, and the locking block is inserted into the corresponding locking wing. The bushing is sleeved with the shaft at the end corresponding to the rotating shaft. Two sets of symmetrically distributed inclined surfaces are provided inside the bushing and the shaft. A limit block is connected to the high point of the inclined surface. Two sets of symmetrically distributed protrusions are connected to the insertion end of the rotating shaft and the bushing. The two sets of protrusions are slidably tangentially connected to the two sets of inclined surfaces.

[0009] The handle is configured to rotate axially along the pipe hole to a locked position and a released position. When the handle is rotated to the locked position, the handle drives the rotating shaft to rotate. When the protrusion of the rotating shaft moves from the low point of the tangent inclined surface to the high point, the bushing moves towards the locking wing, and the quick-release buckle is in the locked state. When the handle is rotated to the released position, the handle drives the rotating shaft to rotate. When the protrusion of the rotating shaft moves from the high point of the tangent inclined surface to the low point, the bushing moves towards the handle, and the quick-release buckle is in the released state.

[0010] A further embodiment of this invention is that a gripping part is connected to the outer surface of the handle.

[0011] A further embodiment of this invention is that the locking wing and the quick-release strap are integrally manufactured.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model is easy to assemble and highly efficient. Operators only need to pull the handle to quickly lock and release the pipe seat, which greatly improves work efficiency and reduces the time required for installing and disassembling the pipe rod.

[0014] 2. This utility model offers reliable clamping. Utilizing the inclined surface fit between the bushing and the rotating shaft, as well as the insertion structure of the locking block and the locking wing, the quick-release clamp can firmly clamp the tube rod in the locked state, effectively preventing loosening and displacement of the tube rod, ensuring the stability of the tube rod connection, and making it suitable for work scenarios requiring high clamping accuracy.

[0015] 3. This utility model has a compact structure. The components are rationally arranged and closely cooperate with each other. The overall device is small in size and can be directly connected for use. It is convenient to use in environments with limited space and will not occupy too much installation space, which is conducive to the miniaturization and integration of equipment design.

[0021] The technical scheme of the utility model will be described clearly and completely in connection with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model protection.

[0022] Embodiment

[0023] As shown in Figs. 1-3 A novel pipe base clamping device, including handle 1 and quick release restraint 11, the center of quick release restraint 11 is provided with pipe hole 10 for pipe rod to pass through, is provided with notch 9 in the circumferential direction, the both sides of notch 9 are connected with locking wing edge 8 respectively, the both connecting arms of handle 1 are connected with the rotation axis 2 of symmetrical distribution respectively, and two groups of locking wing edges 8 are arranged between two groups of rotation axes 2 and are connected through bush 4.

[0024] The end of bush 4 corresponding with locking wing edge 8 is connected with clamping block 5, clamping block 5 is inserted with corresponding locking wing edge 8, the end of bush 4 corresponding with rotation axis 2 is sleeved with rotation axis 2, the end of bush 4 corresponding with rotation axis 2 is provided with two groups of symmetrical distribution inclined surface 6, the high point of inclined surface 6 is connected with limit block 7, the inserted end of rotation axis 2 and bush 4 is connected with two groups of symmetrical distribution convex point 3, and two groups of convex points 3 are slidably connected with corresponding two groups of inclined surface 6.

[0025] The handle 1 is configured to be rotated along the axial direction of the pipe hole 10 to a locking position and a releasing position. When the handle 1 is rotated to the locking position, the handle 1 drives the rotating shaft 2 to rotate, and when the convex point 3 of the rotating shaft 2 moves from the low point position to the high point position of the tangent inclined surface 6, the bushing 4 moves towards the locking wing edge 8, and the quick-release clamp 11 is in the locking state. When the handle 1 is rotated to the releasing position, the handle 1 drives the rotating shaft 2 to rotate, and when the convex point 3 of the rotating shaft 2 moves from the high point position to the low point position of the tangent inclined surface 6, the bushing 4 moves towards the handle 1, and the quick-release clamp 11 is in the releasing state.

[0026] The outer surface of the handle 1 is connected with a holding part 12.

[0027] This arrangement has the following advantages:

[0028] On the one hand, from the perspective of operational convenience, the holding part 12 can provide a more comfortable and hand-fitting gripping area for the operator. Compared with directly holding the handle, it can be designed according to the ergonomic principle, such as adopting a curved surface shape that conforms to the palm curvature, so that the operator's hand is less likely to be tired when frequently rotating the handle for a long time to clamp and release the pipe seat, thereby improving the operation efficiency and reducing the operation errors caused by hand discomfort.

[0029] On the other hand, in terms of safety, the specially designed holding part 12 can further enhance the friction. For example, the surface material can be selected from rubber with high friction coefficient or anti-slip material with more prominent texture, so that the operator can hold the handle stably even in harsh working environments such as wetness and oil stains, and ensure the accuracy and stability of the rotation process, effectively avoiding equipment failure or personal injury caused by the handle slipping.

[0030] Furthermore, for some scenes that require fine operation control of clamping force, the holding part 12 can give the operator more sensitive tactile feedback. Through the close connection with the handle, the operator can more accurately perceive the change of the resistance of the handle rotation, so as to adjust the rotation amplitude appropriately and realize the fine regulation of the clamping degree of the pipe rod, meet the clamping needs of pipe rods with different diameters and different materials, and ensure the reliability of the pipe rod connection.

[0031] The locking wing edge 8 and the quick-release clamp 11 are integrally made.

[0032] This arrangement has the following advantages:

[0033] High structural strength

[0034] The structure manufactured integrally eliminates the connection gap and weak link between the locking wing edge 8 and the quick-release clamp 11, the overall structure is more compact and firm, can withstand greater external force and pressure, and is not prone to breakage, deformation and other conditions during use, thereby improving the reliability and durability of the entire component, and ensuring that the equipment maintains stable performance during long-term operation.

[0035] High manufacturing precision

[0036] The one-piece forming process can better control the dimensional accuracy and geometric tolerance of the locking wing edge 8 and the quick-release clamp 11, reduce the cumulative error that may occur due to 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 problems such as jamming and looseness caused by insufficient manufacturing precision.

[0037] Working principle:

[0038] When assembling the pipe seat clamping device, first insert the clamping block 5 of the bushing 4 into the locking wing edge 8, ensure stable connection, then sleeve the bushing 4 on the rotating shaft 2, make the protrusion 3 of the rotating shaft 2 in tangential contact with the inclined surface 6 of the bushing 4, then fixedly connect the connecting arm of the handle 1 with the rotating shaft 2, complete the preliminary assembly of the device.

[0039] When the pipe rod needs to be clamped, the operator holds the handle 1 and rotates it along the axial direction of the pipe hole 10 to the locking position. In this process, the handle 1 drives the rotating shaft 2 to rotate synchronously, and since the protrusion 3 on the rotating shaft 2 is in sliding tangential connection with the inclined surface 6 in the bushing 4, as the rotating shaft 2 rotates, the protrusion 3 gradually moves from the low point position to the high point position of the inclined surface 6. Under the pushing of the protrusion 3, the bushing 4 moves towards the locking wing edge 8 against a certain resistance, and the clamping block 5 at the end of the bushing 4 further presses the locking wing edge 8, so that the gap 9 of the quick-release clamp 11 gradually narrows, thereby tightly clamping the pipe rod. At this time, the quick-release clamp 11 is in a reliable locking state, and the pipe rod is stably fixed.

[0040] When the pipe rod needs to be disassembled, the operator reversely pulls the handle 1 to rotate it to the release position. The handle 1 drives the rotating shaft 2 to reverse, and the protrusion 3 of the rotating shaft 2 moves from the high point position to the low point position of the inclined surface 6. Under the rebounding action of the locking wing edge 8, the bushing 4 moves towards the handle 1, the pressing force of the clamping block 5 on the locking wing edge 8 is released, the gap 9 of the quick-release clamp 11 returns to its original state, and the pipe rod can be easily taken out, completing the disassembly operation of the pipe rod.

[0041] The examples provided in this utility model are not intended to limit the implementation methods. Those skilled in the art will recognize that various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
