Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing, in particular to an adjustable line fixing device. Background Art

[0002] New energy vehicles involve the connection of various pipelines. If the positions of the pipelines are not fixed, confusion is very easy to occur, especially when the vehicle is bumpy and entangled. This poses a great risk to the safe use of new energy vehicles. Therefore, a line fixing device is needed to fix the pipelines.

Especially for some pipelines with insulating outer skin, the damage of the outer skin poses a great safety risk. Utility Model Content

When the hook is engaged with the bayonet, the inner diameter of the inner fixing clip is the smallest.

Regardless of the first embodiment or the second embodiment, the inner fixing clamp adopts an elastic structure to automatically adjust the outer diameter of the pipeline, so that its inner diameter can adapt to pipelines with different outer diameters.

[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0026] like Figures 1 to 3 As shown, the utility model discloses an adjustable line fixing device, comprising an integrally formed fixing part and a connecting part, the fixing part comprising an outer fixing clamp 1 and an inner fixing clamp 2 coaxially spaced, the inner fixing clamp 2 being annular and having an inner opening 200, so that the inner fixing clamp 2 can shrink toward its axis; the outer fixing clamp 1 is an openable and closable circular ring, a fixed end of which is fixedly connected to the top of the connecting part and formed with a bayonet 101, and a movable end of which is provided with a hook 102 which can be engaged with the bayonet 101, when the hook 102 is separated from the bayonet 101, an outer opening 100 is formed between the two, and the outer opening 100 is communicated with the inner opening 200, so that the pipeline can be inserted into the inner fixing clamp 2 from the outer opening 100 and the inner opening 200; when the hook 102 is engaged with the bayonet 101, the outer fixing clamp 1 applies a centripetal pressure to the inner fixing clamp 2 to shrink the inner fixing clamp 2 toward its axis to clamp the pipeline.

[0027] In this solution, the outer fixing clamp 1 and the inner fixing clamp 2 are coaxially arranged, so that the outer fixing clamp 1 can achieve hard fixation through the buckling of the hook 102 and the bayonet 101, and at the same time, pressure can be applied to the inner fixing clamp 2, so that the inner fixing clamp 2 shrinks the inner diameter to clamp the pipeline (not shown in the figure), thereby achieving soft fixation of the pipeline. Such a structure can prevent the outer wall of the pipeline from being directly clamped by the outer fixing clamp 1 and causing unnecessary wear to the outer wall of the pipeline while the inner fixing clamp 2 fixes the pipeline.

[0028] Furthermore, there is a gap between the outer fixing clamp 1 and the inner fixing clamp 2, and the gap is smaller than the outer diameter of the pipeline, so that the inner fixing clamp 2 can swing to a certain extent relative to the outer fixing clamp 1, thereby producing a shock-absorbing effect on the clamped pipeline, so that the clamped pipeline can fluctuate to a certain extent after being vibrated, thereby reducing the hard contact between the outer wall of the pipeline and the wire fixing device, thereby ensuring the integrity of the outer wall of the pipeline, and ensuring the integrity and safety of the pipeline during use.

[0029] like Figure 1 As shown, the external fixing clip 1 includes an arc-shaped fixed arm 103 and a movable arm 104, wherein the fixed arm 103 is fixedly connected to the top of the connecting portion, and the extended end of the movable arm 104 is the movable end. The fixed arm 103 and the movable arm 104 are movably connected via a hinge 105, so that the movable arm 104 can be flipped relative to the fixed arm 103, so that the hook 102 and the bayonet 101 can be engaged or separated. Such a structure can increase the deformation of the external fixing clip 1 and the width of the external opening 100 to facilitate the insertion of the pipeline. At the same time, the elastic requirements of the external fixing clip 1 itself are reduced, so that the external fixing clip 1 can have a certain hardness, ensure the integrity of its arc shape, and not easily deformed, thereby ensuring the integrity of the internal fixing clip 2, so that its inner diameter forms a circle that matches the outer diameter of the pipeline. In other feasible embodiments, the external fixing clip 1 can also use an elastic integrated structure.

[0030] In this solution, the pipeline is mainly clamped by the inner fixing clamp 2, and the adjustability of this solution to adapt to pipelines with different outer diameters is achieved by the inner fixing clamp 2. The inner fixing clamp 2 has at least two feasible embodiments.

[0031] like Figure 1 and Figure 2 The figure shows a first embodiment of the inner fixing clip 2. In the first embodiment, the inner fixing clip 2 is composed of a group of spring pieces 201, which are distributed along the inner wall of the outer fixing clip 1 at intervals and are bent toward the axis of the outer fixing clip 1 in an arc shape. The axis diameter of the inner fixing clip 2 is jointly defined by the inner ends of the group of spring pieces 201. There is a gap between the inner ends of the spring pieces 201 and the inner wall of the outer fixing clip 1, and the inner diameter of the inner fixing clip 2 can be expanded or reduced by deformation relative to the inner wall of the outer fixing clip 1. When the hook 102 is buckled with the bayonet 101, the inner diameter of the inner fixing clip 2 is the smallest.

[0032] Furthermore, the width of the spring pieces 201 gradually decreases from the outer end to the inner end. The inner diameter of a group of spring pieces 201 gradually decreases from the outer end to the inner end, and the elasticity of the spring pieces 201 enables the spring pieces 201 to adapt to pipelines with different outer diameters to achieve clamping.

[0033] like Figure 2The figure shows a second embodiment of the inner fixing clip 2. In the second embodiment, the inner fixing clip 2 is composed of a first elastic arm 202 and a second elastic arm 203. The fixed end of the first elastic arm 202 is fixed to the end of the movable arm 104 connected to the hinge 105 and is bent at an arc matching the movable arm 104. The fixed end of the second elastic arm 203 is fixed to the end of the fixed arm 103 connected to the hinge 105 and is bent at an arc matching the first elastic arm 202. The movable ends of the first elastic arm 202 and the second elastic arm 203 are arranged at intervals to form the inner opening 200. The structure of the second elastic arm 203 bending toward the first elastic arm 202 gradually reduces the spacing between the first elastic arm 202 and the second elastic arm 203 from the outside to the inside, so as to adapt to pipelines of different outer diameters as much as possible, and ensure that the first elastic arm 202 and the second elastic arm 203 are in a tight fit with the outer walls of pipelines of different outer diameters.

[0034] Furthermore, the movable end of the first elastic arm 202 has a stopper 204 bent toward the inner wall of the movable arm 104, and the stopper 204 is located between the first elastic arm 202 and the movable arm 104 to prevent the first elastic arm 202 from being tightly attached to the movable arm 104, thereby ensuring that the movable arm 104 applies centripetal pressure to the first elastic arm 202.

[0035] like Figure 1-Figure 3 As shown, the connecting part includes a connecting rod 3 and a snap-in spring piece 4. The connecting rod 3 is fixedly connected to the bottom of the fixed arm 103. The two snap-in spring pieces 4 are symmetrically arranged relative to the connecting rod 3, and the bottoms of the two are fixedly connected to the bottom of the connecting rod 3. The three form a claw shape to facilitate the connecting part to be snapped into the component connected thereto.

[0036] Furthermore, the snap-on spring piece 4 includes a vertical section 401 and an inclined section 402, the bottom of the inclined section 402 is fixedly connected to the bottom of the connecting rod 3 and extends obliquely relative to the connecting rod 3, the vertical section 401 is fixedly arranged at the top of the inclined section 402 and extends in the same direction as the connecting rod 3, and a second snap-on opening 403 is arranged on the outer side wall where the vertical section 401 is connected to the inclined section 402. When the connecting portion is snap-oned with other components, the second snap-on opening 403 will snap-on with the edge of the socket of the other component to ensure the connection stability of the connecting portion.

[0037] The connection part further includes a support plate 5, which is horizontally fixed at the connection between the connection rod 3 and the fixed arm 103. Preferably, the support plate 5 has an upward bending arc to increase the connection area between the entire wire fixing device and other components to ensure the connection stability of the connection part.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0039] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
