[0002] In the automotive field, there are many special vehicles or cabs, and the layout requires the wire harness or pipe bundle to meet the corresponding space boundary requirements, and the fixing method of the automobile pipeline will directly affect the reliability of the automobile pipeline. The existing device structure for fixing the wire harness is single, and most of them use ordinary fir-tree-shaped wire harness ties to fix the wires. This structure is prone to damage to the wire harness due to factors such as protection, assembly and consistency differences, and cannot be used in occasions with special layout requirements;

[0003] For example, after the ordinary fir tree-shaped wiring harness ties currently used to fix the wire harness, the wire harness still has a certain amount of room for movement.

Furthermore, sheet metal parts are metal conductors. If the cables are worn, the wires may be exposed and come into contact with the sheet metal parts of the metal conductor, causing a short circuit. In severe cases, it may cause a car fire, which can easily lead to safety accidents. The existing patent application number is CN201621078622.7, and the patent name is a kind of automobile pipeline fixing bracket, which discloses a connected first horizontal plate and vertical plate, and the fixing hole through the cable tie is fixed on the vertical plate, the vertical plate is fixedly connected to the automobile crossbeam, and the pipeline is fixed to the first horizontal plate or the vertical plate through the cable tie; firstly, the sheet metal parts are not all flat structures, some have a certain curvature, and the space between the first horizontal plate and the vertical plate directly exposes the wiring harness to the air, which is easy to contact with other electrical appliances, and the wiring harness cannot be wrapped; secondly, it is also necessary to open a hole on the vertical plate to install the binding tape and then bind the wiring harness. The first horizontal plate also needs bolts to fix it on the sheet metal part. The work process is relatively cumbersome, which increases the difficulty of operation and cannot achieve quick installation. Utility Model Content

[0021] A connecting piece is provided in the pipeline fixing device, so that the connecting piece can be directly connected to the mounting hole of the sheet metal part through the connecting piece, which facilitates the rapid installation and disassembly between the connecting piece and the sheet metal part, avoiding the cumbersome method of the traditional method of using the fixing device to open a hole and threading the mounting hole of the sheet metal part through a bolt; the pipeline fixing device of the present application can be more convenient and quick when the position needs to be moved or replaced, shortening the installation time and improving labor efficiency; one side of the protective piece is connected to the connecting piece, and the other side is connected to the fastener.

[0029] Since the first adjusting end of the adjusting block can be installed and extend out of the second protective plate, and the second adjusting end of the adjusting block is located in the inner cavity and connected to the first protective plate through an adjusting spring, the adjusting block can be used as a positioning structure between the first protective plate and the second protective plate; when in use, the adjusting block needs to be pressed, and the first protective plate can be dragged to slide along the inner cavity of the second protective plate to adjust the position of the first protective plate relative to the second protective plate and adjust the length of the protective part.

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0041] The utility model relates to a pipeline 7 fixing device, such as Figure 1-3 As shown, it includes a connecting member 2, a protective member 3 and a fastener 4; the connecting member 2 is connected to the fixed side of the protective member 3, and the connecting member has a connecting portion that is snap-connected to the sheet metal member 1; a plurality of fasteners 4 are connected to the connecting side of the protective member 3 at intervals, and are used to connect to the pipeline 7, so that the pipeline 7 and the sheet metal member 1 are isolated by the protective member 3; the connecting side of the protective member 3 forms a wrapping portion that can wrap at least a partial area of ​​the circumference of the pipeline 7.

[0042] Since the sheet metal part 1 has a variety of shapes, it is not limited to the sheet metal part 1 with a flat structure, but also has a sheet metal part 1 bent at multiple angles, that is, the sheet metal part 1 has a flange structure. The traditional flat-plate fixing device is easy to contact with the pipeline 7 at the flange structure position, and the flat-plate fixing device has a large space for exposing the pipeline 7, which easily causes the pipeline 7 to touch or rub against the surrounding structure. Therefore, the present application will be provided with a protective part 3 and a fastener 4 connected to the protective part 3, which can enable the pipeline 7 to be firmly locked on the connecting side of the protective part 3. The fixed side of the protective part 3 is used to connect with the sheet metal part 1, so that the pipeline 7 and the sheet metal part 1 are isolated by the protective part 3, and the protective part 3 has a wrapping portion for at least a partial area of ​​the circumference of the pipeline 7, which can achieve a larger range of wrapping and protection for the pipeline 7, effectively preventing most of the pipeline 7 from being exposed to the outside, and reducing the wear of the pipeline 7.

[0043] A connecting piece 2 is provided in the fixing device of the pipeline 7, so that the connecting piece 2 can be directly connected to the mounting hole of the sheet metal part 1 by a snap connection, which is convenient for quick installation and disassembly between the connecting piece 2 and the sheet metal part 1, and avoids the cumbersome method of the traditional method of using a fixing device to open a hole and threading the fixing hole of the sheet metal part 1 through a bolt; the pipeline fixing device of the present application can be moved or replaced more conveniently and quickly, shortening the installation time and improving labor efficiency; one side of the protective piece 3 is connected to the connecting piece 2, and the other side is connected to the fastener 4. By providing the protective piece 3, the pipeline 7 can be located on the side of the protective piece 3 away from the sheet metal part 1, so as to achieve isolation between the pipeline 7 and the sheet metal part 1 and avoid wear between the pipeline 7 and the sheet metal part 1;

[0044] And because the protective member 3 can wrap a part of the area of ​​the pipeline 7, the isolation effect between the pipeline 7 and the electrical components is enhanced, effectively avoiding wear between the pipeline 7 and the electrical components, protecting the pipeline 7 and the electrical components to a certain extent, avoiding short circuits between exposed cables and electrical components caused by wear, and avoiding safety accidents such as fire. When in use, the connector 2 is directly clamped with the sheet metal part 1 to achieve a quick-plug connection, and then the pipeline 7 is passed through the fastener 4 to directly lock the pipeline 7 through the fastener 4, without the need to install the wire harness in the fixing device and then tie the pipeline 7 on site with a binding belt, thereby achieving rapid installation and rapid disassembly, and improving the work efficiency of installation and maintenance.

[0045] The present application does not impose any specific limitation on the structure of the protective element 3, and any of the following implementations may be adopted:

[0046] Implementation method 1: Figure 1 As shown, the protection member 3 comprises a protection plate, a connection side of which has an inner wall surface bent toward the fastener 4 , and the inner wall surface can wrap at least a partial area of ​​the pipeline 7 .

[0047] The purpose of the connecting side of the protective plate being able to bend toward the side of the fastener 4 is to further shorten the space between the protective plate and the fastener 4, so that the pipeline 7 locked by the fastener 4 can be exposed as little as possible in the space formed by the protective plate and the fastener 4 to reduce contact with the outside world. The inner wall surface formed by the protective plate bending toward the fastener 4 can cover at least part of the area of ​​the pipeline 7, thereby making the area of ​​the pipeline 7 contacting the outside world smaller; in this embodiment, the inner wall surface can extend to both sides of the fastener 4, and can also extend to the position between the fastener 4 and the protective plate, and is not limited to the extended position listed in this application. The purpose is to be able to shield the side of the pipeline 7 locked by the fastener 4, so that the pipeline 7 is less exposed to the outside world, thereby protecting the pipeline 7 and preventing the pipeline 7 from wearing against the bent or non-bent sheet metal 1 and other electrical components.

[0048] As a preferred embodiment of the above-mentioned implementation mode, the inner wall surface has outwardly extending extension portions 6 on both sides along the width direction of the protective plate to increase the wrapping area of ​​the pipeline 7.

[0049] The inner wall surface is provided with extension parts 6 extending along both sides of the width direction of the protective plate, the purpose is to further increase the shielding area of ​​the pipeline 7, which can be more suitable for the isolation of sheet metal parts 1 with a wider width range, especially some sheet metal parts 1 with bending angles, such as Figure 2 and Figure 3 The sheet metal 1 shown has a bending structure to form a small flange of the sheet metal 1. Since the sheet metal 1 has a bending portion toward the pipeline 7, the extension portion 6 can be provided to isolate the bending portion of the sheet metal 1, thereby further protecting the side of the pipeline 7 from direct contact or collision with the sheet metal 1, and further avoiding the phenomenon of wear caused by contact between the pipeline 7 and other electrical components.

[0050] Embodiment 2: The protective member 3 includes a first protective plate, a second protective plate and an adjustment component; at least part of the first protective plate can be connected to the inner cavity of the second protective plate through the adjustment component, and the adjustment component is used to make the first protective plate have a first state shortened relative to the second protective plate, and a second state extended relative to the second protective plate.

[0051] By setting the protective member 3 as a first protective plate and a second protective plate, the position of the first anti-slip plate relative to the second protective plate can be adjusted through the adjustment component to achieve the adjustment of the length of the protective member 3, which is more adaptable to the needs of different occasions. The length of the protective member 3 that plays a shielding role can be appropriately adjusted according to the length of the sheet metal part 1, thereby improving practicality.

[0052] Based on this implementation, the structure of the regulating component can adopt the following embodiments:

[0053] Embodiment 1: The adjustment assembly comprises an adjustment block and an adjustment spring, wherein the adjustment block has a first adjustment end which is installed and extends out of the second protective plate, and a second adjustment end which extends into the inner cavity of the second protective plate; the adjustment spring is connected between the second adjustment end and the outer wall of the first protective plate in the inner cavity;

[0054] The adjusting block is configured such that when the first adjusting end is pressed into the inner cavity, the first protective plate can slide along the length direction of the second anti-slip plate.

[0055] Since the first adjusting end of the adjusting block can be installed and extend out of the second protective plate, and the second adjusting end of the adjusting block is located in the inner cavity and connected to the first protective plate through an adjusting spring, the adjusting block can also be used as a positioning structure that can realize the first protective plate and the second protective plate; when in use, the adjusting block needs to be pressed, and the adjusting block extends into the inner cavity. At this time, the first protective plate and the second protective plate are unlocked, and the first protective plate can be dragged to slide along the inner cavity of the second protective plate to adjust the position of the first protective plate relative to the second protective plate, and adjust the length of the protective part 3. The appropriate length can be selected according to needs to adapt to sheet metal parts 1 of different lengths, so as to realize effective isolation between the pipeline 7 and the sheet metal part 1 and other electrical components.

[0056] Furthermore, the second protective plate is provided with a plurality of positioning holes corresponding to the adjustment block, and the adjustment block cooperates with the positioning holes to enable the first protective plate to be connected to the second protective plate by clamping. When the adjustment block is pressed, the first protective plate moves along the inner cavity of the second protective plate, and when it moves to a required length, after the adjustment block reaches the positioning hole at a predetermined position, the adjustment block can be installed outside the positioning hole, so that the position of the first protective plate relative to the second protective plate is fixed.

[0057] Embodiment 2: The adjustment assembly includes an adjustment rod, wherein the adjustment rod has an adjustment portion extending beyond the second protective plate, and a fixing portion extending into the inner cavity of the second protective plate, wherein the fixing portion is connected to the second protective plate.

[0058] Furthermore, the second protective plate is provided with an adjustment hole corresponding to the adjustment rod, and the adjustment hole extends along the length direction of the second protective plate. The adjustment rod can move along the adjustment hole to drive the first protective plate to slide along the second protective plate. When moving to one side of the adjustment hole, the side surface of the adjustment rod can abut against the inner wall of the adjustment hole so that the first protective plate can be clamped and connected to the second protective plate, thereby achieving the extension of the first protective plate relative to the second protective plate.

[0059] It is worth noting that, regardless of the above-mentioned embodiment one or embodiment two, in order to further enhance the connection stability between the first protective plate and the second protective plate, a slide rail can be further provided on the inner wall of the inner cavity of the second protective plate, and a slide groove cooperating with the slide rail can be provided on the outer wall of the first protective plate, so that the slide groove of the first protective plate can move along the slide groove of the second protective plate, and the first protective plate and the second protective plate move along a predetermined trajectory without relative deflection, thereby increasing the stability between the first protective plate and the second protective plate.

[0060] As a preferred embodiment, Figure 1 and Figure 2 As shown, the fastener 4 comprises a connecting ring having a clamp capable of clamping the pipeline 7 .

[0061] The fasteners 4 are provided with multiple strips along the length direction of the protective member 3 to realize multi-directional locking of the pipeline 7. When in use, the pipeline 7 is inserted into the fastener 4 and the fastener 4 is locked by a clamp. The connecting ring can adopt a traditional cable tie or a binding rope or other structural members that can realize locking of the circumference of the pipeline 7;

[0062] Furthermore, the inner wall of the connecting ring is also provided with latching teeth 5, which protrude from the inner wall of the connecting ring to clamp the pipeline 7, thereby increasing the friction between the pipeline 7 and the connecting ring and preventing the pipeline 7 from shaking and deflecting on the inner wall of the connecting ring and causing position changes.

[0063] As a preferred embodiment, the fixing side of the protective member 3 has a contact area with a planar structure, and the contact area can fit with the plane of the sheet metal member 1 to ensure a tight connection between the sheet metal member 1 and the protective member 3 .

[0064] In order to achieve a good fit between the protective part 3 and the sheet metal part 1, since the sheet metal part 1 has a planar structure, it is necessary to set the abutment area where the protective part 3 and the sheet metal part 1 cooperate with each other as a planar structure; if the protective part 3 is set as a structure including a first protective plate, a second protective plate and an adjustment component, it is necessary to set a planar structure on the outer wall surface of the first protective plate and the second protective plate facing the sheet metal part 1, because the first protective plate is installed inside the second protective plate, so the first protective plate needs to be provided with the same planar structure to be more adaptable to the second protective plate, so that the first protective plate can slide smoothly along the second protective plate. Setting a planar structure can also achieve a closer contact area between the sheet metal part 1 and the protective part 3, and compared with the contact area with the sheet metal part 1 when it is set as an arc surface, the connection strength is improved, which prevents the pipeline 7 from shaking too much on the sheet metal part 1 and causing wear on the surrounding structure.

[0065] As a preferred embodiment, Figure 1 As shown, the connecting portion is in a fir-tree-shaped structure, and the connecting portion can be inserted into the mounting hole of the sheet metal component 1 and connected with the mounting hole by snapping.

[0066] The connecting part can adopt the anchor head of the fir tree-type binding tape commonly used in the prior art, and the connecting part can be directly inserted into the mounting hole of the sheet metal part 1 to realize the connection between the sheet metal part 1 and the connecting part, which is more convenient to use. The fir tree-type structure has multiple layers and abutments with gradually increasing diameters, which can effectively prevent the connecting part from falling out of the mounting hole because of its shape similar to that of a fir tree.
