Description

Technical Field

[0001] This utility model belongs to the field of pipe clamp technology, specifically relating to an automotive fuel pipe clamp structure. Background Technology

[0002] Brake and fuel lines are typically secured to the vehicle body using clamps. There are two common types of clamps: one is installed in a small hole in the body bracket, and the other is installed on a welded stud on the body. Because clamps that work with welded studs have greater pull-out force, better reliability, and simpler stud placement, they are less expensive, making this method the mainstream choice.

[0003] Currently, there are two main types of pipe clamps that work with welding studs. One type uses an interference fit between the clamp and the stud, requiring a large assembly force and cannot be assembled by hand; it requires tapping with a rubber mallet. The other type uses a toothed mounting hole for the clamp, which engages with the welding stud. Both types of clamps require the selection of a suitable stud during installation, resulting in a narrow range of applications. Additionally, when the fuel line is clamped, the fuel line vibrates as fuel at a certain pressure and flow rate is pumped to the engine, and this vibration is transmitted to the vehicle body. Utility Model Content

[0004] Based on the problems mentioned in the background art above, this utility model provides an automotive fuel line clamp structure to solve the problem that current fuel line clamps require matching studs for installation, resulting in a narrow range of applications; and that when the fuel line clamps hold the fuel line in use, the fuel line vibrates when fuel at a certain pressure and flow rate is delivered to the engine through the fuel pump, which in turn causes the vibration to be transmitted to the vehicle body.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A fuel line clamp structure for automobiles, comprising:

[0007] A substrate, wherein a screw cylinder is provided on one side of the middle portion of the substrate;

[0008] A clamping assembly, wherein the clamping assembly is disposed on a screw barrel;

[0009] The fixing components are provided in two, and the two fixing components are respectively disposed on one side of the substrate facing opposite ends, and the two fixing components are located on the same side as the screw barrel;

[0010] Two buffer mounting bases are provided, and each is detachably installed inside a corresponding fixing component;

[0011] Two jacket assemblies are provided, each disposed inside a corresponding buffer mounting base.

[0012] Based on the above technical solution, the present invention has made the following improvements:

[0013] Furthermore, the clamping assembly includes four slots, which are arranged in a circular array on the peripheral sidewall of the screw barrel. Each slot contains a conical block, and each slot has a hole on its sidewall. A stabilizing plate passes through each hole, and each conical block has a through groove. Each stabilizing plate is clamped in its corresponding through groove, and a stabilizing post passes through each through groove. Each stabilizing plate is fitted onto its corresponding stabilizing post, and a return spring is fitted onto the post located between one side of the stabilizing plate and the sidewall of the through groove. A threaded sleeve is screwed into the screw barrel, and the screwed end of the threaded sleeve has a flared opening.

[0014] Furthermore, the fixing component includes a fixing U-shaped seat, which is fixedly disposed at one end of the substrate. The fixing U-shaped seat has an installation groove inside, and a limit spring plate is provided on the top groove wall of the installation groove.

[0015] Furthermore, the buffer mounting base includes an intermediate U-shaped base, which is securely fastened in the mounting groove. An assembly groove is provided inside the intermediate U-shaped base, and a buckle plate is provided at the top opening of the assembly groove. Multiple mounting holes are arrayed on each vertical side wall of the assembly groove. A stabilizing cylinder is securely fastened in each mounting hole. A movable cylinder and a spring are provided inside each stabilizing cylinder. The spring is located between the bottom of the stabilizing cylinder and the bottom of the movable cylinder. A limit groove is provided on each stabilizing cylinder, and a limit post is provided on each movable cylinder. Each limit post is located in the corresponding limit groove.

[0016] The inner bottom array of the intermediate U-shaped seat is provided with multiple assembly holes. Each assembly hole is fastened with a stabilizing sleeve. Each stabilizing sleeve is provided with a movable sleeve and a second spring. The second spring is located between the inner bottom of the stabilizing sleeve and the inner bottom of the movable sleeve. Each side wall of the stabilizing sleeve is provided with a second limiting groove. Each side wall of the movable sleeve is provided with a second limiting post. Each second limiting post is located in the corresponding second limiting groove.

[0017] Furthermore, the clamping assembly includes a clamping U-shaped seat, which is disposed in the area enclosed by each movable cylinder and each movable sleeve. One end of each movable cylinder abuts against the corresponding vertical outer wall of the clamping U-shaped seat, and one end of each movable cylinder abuts against the outer bottom wall of the clamping U-shaped seat. Each of the two vertical inner walls of the clamping U-shaped seat is provided with a receiving groove, and a spring plate is provided at the top of each receiving groove.

[0018] The beneficial effects of this utility model are:

[0019] 1. By using the combination of the screw and clamping components, the screw is inserted into the mounting post in the vehicle body during use, and then the clamping components are used to stably install the pipe clamp structure on the mounting post of the vehicle body. The clamping size of the clamping components is adjustable, thereby expanding the installation application range of the pipe clamp structure.

[0020] 2. By setting up a combination of fixed components, buffer mounting base and jacket assembly, the fixed components are used to assemble the buffer mounting base, and the buffer mounting base is used to assemble the jacket assembly. The jacket assembly is used to clamp and stabilize the fuel line during use. Since the buffer mounting base is set between the fixed components and the jacket assembly, when the fuel line vibrates, its vibration is not easily transmitted to the fixed components and the base plate, and ultimately will not be transmitted to the vehicle body.

[0026] like Figures 1-2 As shown, the technical solution adopted by this utility model is as follows:

[0027] A fuel line clamp structure for automobiles, comprising:

[0028] A substrate 101, with a screw cylinder 102 disposed on one side of the middle portion of the substrate 101;

[0029] A clamping assembly is mounted on the screw cylinder 102. The clamping assembly includes four slots 201 arranged in a circular array on the circumferential sidewall of the screw cylinder 102. Each slot 201 contains a conical block 202. Each slot 201 has a hole 203 on its sidewall, and a stabilizing plate 205 passes through each hole 203. Each conical block 202 has a through groove 204, and each stabilizing plate 205 is fitted into its corresponding through groove 204. Each through groove 204 contains a stabilizing post 206, and each stabilizing plate 205 is sleeved on its corresponding stabilizing post 206. Each stabilizing post 206, located between one side of the stabilizing plate 205 and the sidewall of the through groove 204, is fitted with a return spring 207. The combination of the through groove 204, stabilizing plate 205, stabilizing column 206, and return spring 207 enables the conical block 202 to be movably assembled into the slot 201 on the screw cylinder 102. The return spring 207 keeps the conical wall of the conical block 202 outside the screw cylinder 102 when the conical wall is not compressed. A threaded sleeve 208 is screwed into the screw cylinder 102, and the screw-in end of the threaded sleeve 208 is provided with a flared end 209. When the threaded sleeve 208 is rotated to move closer to the root of the screw cylinder 102, the inner wall of the flared end 209 of the threaded sleeve 208 can simultaneously compress the conical wall of each conical block 202, causing each conical block 202 to move synchronously into the screw cylinder 102, and causing each return spring 207 to contract and store force.

[0030] In use, the screw cylinder 102 is inserted into the mounting post in the vehicle body, and then the screw sleeve 208 is rotated to move it along the direction close to the root of the screw cylinder 102. During the movement, the inner wall of the flared part 209 on the screw sleeve 208 can simultaneously squeeze the conical wall of each conical block 202, so that each conical block 202 moves into the screw cylinder 102 simultaneously. At this time, each return spring 207 is contracted and stores force, so that the inserted end of each conical block 202 is respectively arrayed and clamped on the peripheral side wall of the mounting post, thereby making the pipe clamp structure stably installed on the mounting post of the vehicle body. Since the position of each conical block 202 is movable, the size of the mounting post it clamps is adjustable, thereby expanding the installation application range of the pipe clamp structure.

[0031] The fixing components are provided in two parts, which are respectively located on one side of the substrate 101 at opposite ends, and the two fixing components are located on the same side as the screw cylinder 102. The fixing components include a fixing U-shaped seat 301, which is fixedly installed on one end of the substrate 101. The fixing U-shaped seat 301 is provided with a mounting groove 302, and the top groove wall of the mounting groove 302 is provided with a limiting spring plate 303. The limiting spring plate 303 can be flipped along its root.

[0032] The buffer mounting base has two components, each detachably mounted inside its corresponding fixing component. Each buffer mounting base includes a central U-shaped base 401, the size and structure of which are adapted to the size and structure of the mounting groove 302. During assembly, the central U-shaped base 401 is inserted downwards along the top opening of the mounting groove 302. During insertion, the side wall of the central U-shaped base 401 presses against the limiting spring plate 303, causing the limiting spring plate 303 to flip and fit closer to the groove wall of the mounting groove 302. When the central U-shaped base 401 is fully inserted into the mounting groove 302, the limiting spring plate 303 rebounds and resets, causing its bottom to abut against the top of the buckle plate 403, thus preventing the central U-shaped base 401 from detaching from the mounting groove 302 and ensuring the central U-shaped base 401 is securely locked into the mounting groove 302.

[0033] An assembly groove 402 is provided inside the middle U-shaped seat 401. A buckle plate 403 is provided at the top opening of the assembly groove 402. The buckle plate 403 closes the top opening of the assembly groove 402 and provides vertical limitation for clamping the U-shaped seat 501.

[0034] Multiple mounting holes 404 are arrayed on each vertical sidewall of the assembly slot 402. A stabilizing cylinder 405 is securely fitted into each mounting hole 404. A movable cylinder 406 and a spring 407 are installed in each stabilizing cylinder 405. The spring 407 is located between the bottom of the stabilizing cylinder 405 and the bottom of the movable cylinder 406. A limiting groove 408 is provided on each stabilizing cylinder 405. A limiting post 409 is provided on each movable cylinder 406. Each limiting post 409 is located in the corresponding limiting groove 408. Through the combination of the stabilizing cylinder 405, the movable cylinder 406 and the spring 407, some buffer components are provided on the vertical inner sidewall of the intermediate U-shaped seat 401.

[0035] The inner bottom of the intermediate U-shaped seat 401 is provided with multiple assembly holes 410. Each assembly hole 410 is fastened with a stabilizing sleeve 411. Each stabilizing sleeve 411 is provided with a movable sleeve 412 and a second spring 413. The second spring 413 is located between the inner bottom of the stabilizing sleeve 411 and the inner bottom of the movable sleeve 412. Each side wall of the stabilizing sleeve 411 is provided with a second limiting groove 414. Each side wall of the movable sleeve 412 is provided with a second limiting post 415. Each second limiting post 415 is located in the corresponding second limiting groove 414. Through the combination of the stabilizing sleeve 411, movable sleeve 412 and second spring 413, some buffer components are also provided on the inner bottom wall of the intermediate U-shaped seat 401. The buffer components on the inner bottom wall of the intermediate U-shaped seat 401 can also be used as load-bearing components.

[0036] The clamping assembly has two parts, each disposed inside a corresponding buffer mounting base. The clamping assembly includes a clamping U-shaped base 501. Before inserting the middle U-shaped base 401 into the mounting groove 302, the clamping U-shaped base 501 is placed in the area enclosed by each movable cylinder 406 and each movable sleeve 412, so that one end of each movable cylinder 406 abuts against the corresponding vertical outer wall of the clamping U-shaped base 501, and one end of each movable cylinder 406 abuts against the outer bottom wall of the clamping U-shaped base 501. Finally, the buckle plate 403 is assembled into the top groove of the assembly groove 402, so that the buckle plate 403 abuts against the top of the clamping U-shaped base 501, preventing the clamping U-shaped base 501 from detaching from the area enclosed by each movable cylinder 406 and each movable sleeve 412, so that the clamping U-shaped base 501 is always kept in the area enclosed by each movable cylinder 406 and each movable sleeve 412.

[0037] The clamping U-shaped seat 501 has two vertical inner walls with receiving grooves 502. Each receiving groove 502 has a spring plate 503 at the top. The spring plate 503 can be flipped along its root so that it can be stored in the receiving groove 502.

[0038] After all components are assembled, the fuel line is inserted into the top groove of the clamping U-shaped seat 501. During insertion, the fuel line squeezes the spring plate 503, causing it to flip and be stored in the receiving groove 502. When the fuel line is stuck at the bottom of the clamping U-shaped seat 501, the spring plate 503 flips back to its original position, so that the bottom end of the spring plate 503 abuts against the top peripheral wall of the fuel line, thereby clamping and securing the fuel line. When the fuel line vibrates, due to the combination of the stabilizing sleeve 411, the movable sleeve 412 and the second spring 413, the clamping U-shaped seat 501 will not have direct hard contact with the intermediate U-shaped seat 401. Therefore, when the fuel line vibrates, the vibration is not easily transmitted to the fixed U-shaped seat 301 and the base plate 101, and ultimately will not be transmitted to the vehicle body.
