Description

Technical Field

[0001] The utility model relates to the technical field of automotive pipelines, and particularly relates to a fixing pipe clamp for fuel and steam pipelines. Background Art

[0002] Automobile fuel and fuel vapor need to be transported from the fuel tank at the rear end of the vehicle body to the engine at the front end, with a relatively long span from front to back. Many vehicle manufacturers choose to arrange the fuel and fuel vapor pipelines in the longitudinal beam of the vehicle body. On the one hand, it can protect the pipelines and avoid damage caused by stone impacts and scratches on the chassis. On the other hand, it can save multiple pipeline fixing pipe clamps and reduce costs. However, due to the long pipeline and the lack of positioning and support in the longitudinal beam, and being fixed only at both ends of the pipeline, the requirement for positioning accuracy is relatively high. Otherwise, there will be a certain length margin for the pipeline, and the pipeline attitude is uncertain, making it easy to contact the surrounding sheet metal, resulting in the transmission of high-frequency fuel pulses and carbon canister solenoid valve pulse vibrations to the vehicle body, generating noise.

[0003] Currently, the commonly used pipe clamp for fixing fuel and steam pipelines is a double pipe clamp. The fixing point of this pipe clamp is a single stud, and the pipe clamp has one degree of freedom on the plane and can rotate around the stud, giving the pipeline a certain amount of movement, which will lead to inaccurate limiting.

[0004] Moreover, the existing patent also discloses an automotive fuel pipe clamp, which includes a pipe clamp body, a pipeline positioning hole on the pipe clamp body for positioning the fuel pipeline, a one-way barb structure at the lower part of the pipe clamp body for cooperating with the mounting hole on the vehicle body, and a buffer pad for increasing the contact area with the vehicle body at the root of the one-way barb structure at the lower part of the pipe clamp body. However, this installation structure of the one-way barb structure, like the stud installation structure, still has one degree of freedom on the installation and fixing plane, resulting in a certain amount of rotational movement of the entire pipe clamp around the one-way barb structure on the installation and fixing plane, thus leading to incomplete fixing. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the problem that the existing pipe clamp for fuel and steam pipelines has a certain amount of rotational movement on the installation and fixing plane, resulting in incomplete fixing, and to provide a fixing pipe clamp for fuel and steam pipelines, which can completely limit all degrees of freedom of the fuel and steam pipelines, make them completely fixed, and prevent displacement or rotation.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A fixing pipe clamp for fuel and steam pipelines includes a base, a clamping groove part, and a fixing part; the base includes a bottom plate and side plates fixedly connected to both ends of the bottom plate, the clamping groove part is installed on the base; the fixing part includes fixing claws located opposite to each other on the two side plates respectively, and the fixing claws are used for snap connection with the fixing holes at the installation position.

[0008] In the above technical solution, the fuel pipe and the steam pipe are first installed on the clamping groove portion of the pipe clamp, and then the entire base is moved to the installation position of the vehicle body, and the fixing portion is installed on the vehicle body longitudinal beam, so that the fixing claws are engaged with the fixing holes of the vehicle body longitudinal beam, completely restricting the base so that the base cannot rotate relative to the vehicle body longitudinal beam.

[0009] Among them, the fixing claw can generally be connected by clamping with the claw or by clamping with the hole. In the utility model, the clamping connection function of the fixing claw is to completely fix the pipe clamp so that its degree of freedom is zero and there is no rotational activity. The clamping of the fixing claw and the claw cannot achieve this effect. Therefore, only fixing holes can be set on the longitudinal beam of the vehicle body to engage with the fixing claws of the pipe clamp.

[0010] Furthermore, the fixing part also includes a positioning boss, which is located on the base plate between the fixing claws on both sides and is fixedly connected to the base plate, and the positioning boss is used to engage with the positioning hole at the installation position; the setting of the positioning boss enables the operator to quickly position the base on the vehicle body, facilitating the rapid engagement and installation of the fixing claws.

[0011] Furthermore, the shape of the positioning boss can be any shape except circular; the positioning boss is set to be non-circular, and the base is kept in a fixed direction when installed into the positioning hole, limiting the rotation of the entire base to facilitate the subsequent engagement of the fixing claw with the sheet metal hole.

[0012] Furthermore, the side panels are each provided with a disassembly hole, and the disassembly hole is located below the fixing claw; during disassembly, it is only necessary to insert a screwdriver perpendicular to the side panel into the disassembly hole and then pry it to disassemble, thereby improving the convenience of disassembly.

[0013] Furthermore, the slot portion includes a first slot for installing a fuel pipe and a second slot for installing a steam pipe, and the first slot and the second slot are arranged side by side in a direction perpendicular to the side panel; reinforcing ribs are connected between the first slot and the second slot, between the first slot and the side panel, and between the second slot and the side panel; the sizes of the first slot and the second slot respectively match the sizes of the fuel pipe and the steam pipe to achieve pipeline restriction.

[0014] Furthermore, shock-absorbing pads are provided on the surfaces of the first card slot and the second card slot; the shock-absorbing pads are made of TPE material and have the function of buffering and vibration isolation.

[0015] Furthermore, the top of the first card slot and the second card slot are also provided with undercuts for improving the stability of the engagement; the undercuts press the pipeline against the bottom surface of the card slot in the vertical direction, preventing the card slot engagement connection from falling off due to bumps and vibrations during driving of the vehicle.

[0016] Furthermore, the reverse buckle is in the shape of a right trapezoid; the inclined surface of the right trapezoid is the pipe installation clamping surface, which is convenient for the smooth clamping of the pipeline.

[0017] Furthermore, it further includes a limiting mechanism corresponding to the clamping groove portion, and the limiting mechanism is fixedly connected to the bottom plate and the side plate; the limiting portion restricts the axial movement of the pipeline on the clamping groove, and completely fixes the pipeline on the pipe clamp.

[0018] Furthermore, the limiting mechanism is at least provided with a first limiting member and a second limiting member. Along the central axis direction of the base, the first limiting member is at least provided with two first limiting grooves, and the central axis of the first limiting groove is collinear with the central axis of the first clamping groove. Along the central axis direction of the base, the first limiting member is at least provided with two second limiting grooves, and the central axis of the second limiting groove is collinear with the central axis of the second clamping groove; reinforcing ribs are connected between the first limiting member and the second limiting member, between the first limiting member and the side plate, and between the second limiting member and the side plate.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The fixing claws of the fixing part are engaged with the body sheet metal holes, completely restricting the degrees of freedom of the pipe clamp and having no rotational movement, effectively preventing it from rotating.

[0021] 2. A limiting mechanism is arranged on one side of the fixing part to restrict the axial movement of the pipeline stuck on the first and second clamping grooves, further completely fixing the pipeline on the base of the pipe clamp and preventing the pipeline from axially moving.

[0029] Embodiment 1

[0030] This embodiment is the first embodiment of a fuel and steam pipe fixing pipe clamp. As Figures 1 to 2 shown, it includes a base 1, a card slot portion 2, and a fixing portion 3; the base 1 includes a bottom plate 101 and side plates 102 fixedly connected to both ends of the bottom plate 101, and the card slot portion 2 is installed on the base 1; the fixing portion 3 includes fixing claws 301 located opposite each other on the two side plates 102, and the fixing claws 301 are used for snap connection with the fixing holes at the installation position.

[0031] Specifically, the fixing portion 3 further includes a positioning boss 302, which is located on the bottom plate 101 between the two fixing claws 301 and fixedly connected to the bottom plate 101. The positioning boss 302 is used for snap connection with the positioning holes at the installation position; the setting of the positioning boss 302 enables the operator to quickly position the base 1 on the vehicle body, facilitating the quick snap installation of the fixing claws 301.

[0032] Specifically, the shape of the positioning boss 302 can be any shape other than circular; the positioning boss 302 is set to be non-circular, which keeps the base 1 in a fixed direction when installed into the positioning hole, restricting the rotation of the entire base 1, so as to facilitate the subsequent snap connection of the fixing claws 301 with the sheet metal holes.

[0033] Specifically, disassembly holes 303 are provided on both side plates 102, and the disassembly holes 303 are located below the fixing claws 301; during disassembly, only need to insert a screwdriver perpendicular to the side plate 102 into the disassembly hole 303 and then pry to disassemble, which improves the convenience of disassembly.

[0034] During the operation of the above embodiment, the fuel pipe and the steam pipe are first installed on the slot portion 2, and then the base 1 is moved so that the positioning hole on the vehicle body longitudinal beam engages with the positioning protrusion. Finally, the base 1 is pressed so that the fixing claw 301 is snap-connected with the positioning hole on the vehicle body longitudinal beam, further fixing the entire base 1 on the vehicle body longitudinal beam. When disassembly is required, a screwdriver is inserted into the disassembly hole 303, the fixing claw 301 is separated from the positioning hole, and the entire base 1 is taken out.

[0035] The beneficial effects of this embodiment are as follows: through the snap connection between the fixing claw 301 and the positioning hole of the vehicle body longitudinal beam and the further restriction of the positioning protrusion, the base 1 is completely restricted, so that the base 1 cannot rotate relative to the vehicle body longitudinal beam, thereby preventing the fuel pipe and the steam pipe from rotating. When disassembling, the fixing claw 301 is pried up through the disassembly hole 303, which is easy to operate.

[0036] Example 2

[0037] This embodiment is a second embodiment of a fuel and steam pipe fixing clamp. Figures 1 to 3 As shown, this embodiment is similar to the first embodiment, except that:

[0038] Specifically, the slot portion 2 is provided with a first slot 201 for installing a fuel pipe and a second slot 202 for installing a steam pipe. The first slot 201 and the second slot 202 are arranged side by side in a direction perpendicular to the side plate 102. The first slot 201 and the second slot 202, the first slot 201 and the side plate 102, and the second slot 202 and the side plate 102 are all fixedly connected by reinforcing ribs. The sizes of the first slot 201 and the second slot 202 respectively match the sizes of the fuel pipe and the steam pipe, thereby achieving pipeline restriction.

[0039] Specifically, shock-absorbing pads 203 are further provided on the surfaces of the first card slot 201 and the second card slot 202 ; the shock-absorbing pads 203 are made of TPE material and have the function of buffering and vibration isolation.

[0040] Specifically, undercuts 204 are provided on the top of the first slot 201 and the second slot 202 to improve the stability of the engagement; the undercuts 204 press the pipeline against the bottom surface of the slot in the vertical direction to prevent the slot engagement connection from falling off due to bumps and vibrations during driving of the vehicle.

[0041] Specifically, the undercut 204 is in the shape of a right-angled trapezoid; the inclined surface of the right-angled trapezoid is the pipe installation insertion surface, which facilitates the smooth insertion of the pipe.

[0042] During operation of the above embodiment, the fuel pipe and the steam pipe are respectively installed on the first slot 201 and the second slot 202. When the vehicle is running and bumps, the shock-absorbing pad 203 first buffers the vibration transmitted to the pipe to reduce its amplitude, and then blocks the pipe through the undercut 204 to stably fix the pipe on the slot.

[0043] The beneficial effects of this embodiment are as follows: by providing the shock-absorbing pad 203 and the undercut 204 , the pipeline is prevented from being separated from the slot due to bumps during the driving of the vehicle, thereby improving the stability of the pipeline engaged with the slot.

[0044] Example 3

[0045] This embodiment is a third embodiment of a fuel and steam pipe fixing clamp. Figures 1 to 4 As shown, this embodiment is similar to the first embodiment, except that:

[0046] Specifically, each side panel 102 is provided with a disassembly hole 303 , which is located below the fixing claw 301 . When disassembling, it is only necessary to insert a screwdriver perpendicular to the side panel 102 into the disassembly hole 303 and then pry it to disassemble, thereby improving the convenience of disassembly.

[0047] Specifically, it also includes a limiting mechanism 4 corresponding to the slot portion 2, which is fixedly connected to the bottom plate 101 and the side plate 102; the limiting mechanism 4 limits the axial movement of the pipeline on the slot and completely fixes the pipeline on the pipe clamp.

[0048] Specifically, the limiting mechanism 4 is provided with at least a first limiting member 401 and a second limiting member 402, the central axis of the first limiting member 401 is collinear with the central axis of the first card slot 201, and the central axis of the second limiting member 402 is collinear with the central axis of the second card slot 202; the first limiting groove 4011 and the second limiting groove 4021 are arranged side by side in a direction perpendicular to the side panel 102, the first limiting groove 4011 and the second limiting groove 4021, the first limiting groove 4011 and the side panel 102, and the second limiting groove 4021 and the side panel 102 are fixedly connected by reinforcing ribs, and the first limiting member 401 and the second limiting member 402 are arranged along the central axis direction of the base 1 and are both provided with at least the first limiting groove 4011 and the second limiting groove 4021.

[0049] During the working process of the above embodiments, after the pipeline is clamped into the first clamping groove 201 and the second clamping groove 202, the pipeline is further clamped with the first limiting member 401 and the second limiting member 402 of the limiting mechanism 4 respectively. A number of protrusions are provided on the pipeline, and the protrusions on the pipeline are installed at positions between the first limiting groove 4011 and the second limiting groove 4021 of the limiting member. When the pipeline axially moves, the first limiting groove 4011 or the second limiting groove 4021 contacts and collides with the positioning protrusions on the pipeline, hindering the movement of the pipeline. The limiting mechanism 4 is provided with at least a first limiting member 401 and a second limiting member 402. Along the central axis direction of the base 1, the first limiting member 401 is provided with at least two first limiting grooves 4011, and the central axis of the first limiting groove 4011 is collinear with the central axis of the first clamping groove 201. Along the central axis direction of the base 1, the first limiting member 401 is provided with at least two second limiting grooves 4021, and the central axis of the second limiting groove 4021 is collinear with the central axis of the second clamping groove 202. Reinforcing ribs are connected between the first limiting member 401 and the second limiting member 402, between the first limiting member 401 and the side plate 102, and between the second limiting member 402 and the side plate 102.

[0050] The beneficial effect of this embodiment: The setting of the limiting groove can further prevent the pipeline from axially moving on the base 1 and completely fix the pipeline.
