Description

Technical Field

[0001] The utility model relates to the technical field of oil tank pipeline fixing structures, and specifically relates to a pipe clamp for fixing pipelines in a fuel tank. Background Art

[0002] The oil pipes on the fuel tank are generally fixed on the outer surface of the fuel tank. With the development of technology, the oil pipes are gradually changed from external fixation to internal fixation. The effect of fixing the oil pipes is achieved by installing fixed pipe clamps on the inner surface of the fuel tank. Generally, the fixed pipe clamps of the oil pipes are open-type and fixed with interference fit to improve the clamping force of the oil pipes, thereby avoiding the phenomenon of the oil pipes being detached from the clamps.

[0003] When a vehicle is driving, it will inevitably pass through uneven roads and the fuel tank will be bumpy. At this time, the oil pipe will inevitably shake, and the interference fit will result in no movable margin in the oil pipe, which will easily cause additional wear and reduce its service life. At the same time, when the oil pipe needs to slide along the axial direction, the fixing method will increase friction and make adjustment difficult. Furthermore, in order to meet the requirements for the direction of the oil pipe and avoid unnatural bending of the oil pipe, the position accuracy of the fixed pipe clamp of the oil pipe is required to be higher and higher, resulting in increasing accuracy and difficulty in installing the fixed pipe clamp. Therefore, it is necessary to improve and optimize the existing technology. Utility Model Content

[0042] Embodiment 1, refer to Figure 1~Figure 3 , which is the first embodiment of the utility model, provides a pipe clamp for fixing the pipeline in the fuel tank.

[0043] In this embodiment, the fixed pipe clamp specifically includes a base 1, a clamp ring 2, a rib 1 3 and a rib 2 4; the clamp ring 2 has an inner arc surface, and the rib 1 3 and the rib 2 4 are both arranged on the inner arc surface and are spaced apart; when in use, the base 1 is mounted on the inner wall of the fuel tank by welding, and the oil pipe is clamped in the clamping pipe space 5, and the oil pipe is elastically squeezed and fixed by the elastic rib 2 4 to avoid hard squeezing and protect the pipeline; at the same time, by the elastic deformation of the rib 2 4, the size of the clamping pipe space 5 can be adjusted within a certain range, thereby adapting to oil pipes of different thicknesses and improving the applicable scope of the fixed pipe clamp. With the suspended support of the rib 1 3, the rib 2 4 is elastically squeezed, so that the oil pipe is well supported, and the built-in oil pipe is allowed to move freely axially and radially on the clamp ring 2; when the vehicle passes through an uneven road surface, the rib 1 3 and the rib 2 4 can play a buffering role, reduce abnormal wear of the oil pipe, and extend the service life of the fixed pipe clamp.

[0044] Example 2, refer to Figure 1~Figure 4 , which is the second embodiment of the utility model. On the basis of the first embodiment, this embodiment further adds a slider 7, a connecting unit 8 and an anti-detachment platform 15. The connecting unit 8 includes a connecting sleeve 9, a connecting rod 10 and a spring 11; wherein the base 1 is provided with an annular groove 6 and a loading and unloading groove 12 which are interconnected, and the number of the connecting unit 8 and the loading and unloading groove 12 are both two, which are arranged one by one, and the base 1 is provided with a first groove 13 and a second groove 14 which are connected in sequence.

[0045] When in use, the base 1 is first welded to the inner wall of the fuel tank; then the two sliders 7 are squeezed in a direction approaching each other, the sliders 7 squeeze the connecting sleeve 9, the connecting sleeve 9 squeezes the spring 11, and the spring 11 contracts to accumulate elastic force; when the distance between the two sliders 7 is reduced to a certain size, the two sliders 7 correspond to a loading and unloading groove 12 respectively, and the sliders 7 are clamped into the corresponding loading and unloading grooves 12; the external force applied to the two sliders 7 is removed, the springs 11 release the accumulated elastic force, and push the sliders 7 to slide in the loading and unloading grooves 12, and the sliders 7 slide in the direction close to the annular groove 6 until the sliders 7 separate from the loading and unloading grooves 12 and enter the annular groove 6, at which time the sliders 7 can slide circumferentially along the annular groove 6; the sliding of the sliders 7 in the annular groove 6 drives the rotation of the clamping ring 2 on the base 1, and the direction of the clamping ring 2 is adjusted, and the direction of the clamping pipe space 5 changes accordingly, thereby being able to adapt to oil pipes with different directions.

[0046] At the same time, the rotation of the clamp ring 2 can buffer the slight twisting of the oil pipe during the driving of the vehicle, reduce the hard squeezing clamping force between the clamp ring 2 and the oil pipe, and improve the service life of the fixed pipe clamp and the oil pipe; with the help of the loading and unloading groove 12, the clamp ring 2 can be replaced separately, and the modularization and independent maintenance of parts can be realized, reducing the replacement and maintenance costs; at the same time, with the rotation connection between the clamp ring 2 and the base 1, it is only necessary to ensure the position accuracy of the base 1, reducing the orientation accuracy requirements of the clamp ring 2 and the overall installation accuracy requirements. With the help of the circumferentially distributed connection unit 8 and the loading and unloading groove 12, the symmetry of the force on the clamp ring 2 is guaranteed, and the stability of the installation of the clamp ring 2 is improved.

[0047] When the oil pipe is displaced, the oil pipe generates an extrusion force on the clamping ring 2 through the rib 1 3 and the rib 2 4, and the clamping ring 2 drives the anti-detachment platform 15 to displace synchronously. At this time, the anti-detachment platform 15 is displaced in the second groove 14; the anti-detachment platform 15 is in the shape of a boss, and the first groove 13 and the second groove 14 are both circular and coaxially arranged, and the size of the second groove 14 is larger than that of the first groove 13; with the help of the size difference between the first groove 13 and the second groove 14, the anti-detachment platform 15 is clamped in the second groove 14 after displacement to avoid disengagement, thereby increasing the stability of the direct connection between the clamping ring 2 and the base 1; at the same time, the displacement of the clamping ring 2 can be limited by the size of the first groove 13 to prevent the displacement of the clamping ring 2 from being too large, causing the fixed pipe clamp to fail.

[0048] Example 3, refer to Figure 1~Figure 3 , which is the third embodiment of the utility model. On the basis of the first embodiment, this embodiment further adds a limit block 16, wherein the number of ribs 1 3, ribs 2 4 and limit blocks 16 are all two, which are symmetrically distributed on the clamping ring 2; the symmetrically distributed ribs 1 3 and ribs 2 4 ensure the uniformity of the force on the oil pipe, and avoid bending, deformation and the like caused by unilateral force on the oil pipe; the rib 2 4 squeezed by the oil pipe will elastically deform in the direction away from the rib 1 3, and the rib 2 4 gradually approaches the limit block 16. When the rib 2 4 is squeezed and contacted with the limit block 16, the rib 2 4 reaches the maximum deformation, and the deformation of the rib 2 4 is limited by the limit block 16 to prevent the rib 2 4 from being deformed too much, causing irreversible deformation and the failure of the oil pipe clamping.

[0049] Embodiment 4, referring to Figure 1 , which is the fourth embodiment of the utility model. On the basis of the first embodiment, this embodiment further adds a plurality of welding platforms 17. When the base 1 is welded, the welding platform 17 can be embedded in the inner wall of the fuel tank to increase the contact surface and improve the stability of the connection between the base 1 and the inner wall of the fuel tank.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
