Description

Technical Field

[0001] The present application relates to the technical field of glass lifters, and in particular to a fixing clamp and a connection kit for clamping pipelines. Background Art

[0002] Compared to other types of window lifters, rope-type window lifters are widely used in small cars due to their fewer parts, lighter weight, easier processing, and smaller footprint. However, rope-type window lifters utilize a moving wire to drive the glass bracket. During operation, the wire can easily vibrate and rub or contact other components within the door, causing unusual noises during the glass raising and lowering process, which significantly degrades the user experience. Utility Model Content

[0003] To address the aforementioned issues, this application provides a fixing clamp and connection kit for securing pipelines. These features feature an ingenious design and simple structure. The clamp supports and restrains the pipelines, while a ball-joint structure frees the clamp to rotate freely, reducing the risk of pipeline twisting and damage and unusual noise during window raising and lowering. Furthermore, by providing openings on both sides of the slot, the force required to squeeze the pipeline into the slot is reduced, facilitating installation. The technical solutions employed in this application are as follows:

[0004] A fixing clamp for clamping a pipeline, wherein one end of the fixing clamp is a clamping portion and the other end is a ball head, the clamping portion and the ball head are connected by a connecting portion; the clamping portion is provided with a clamping slot, the clamping slot is used to clamp the pipeline, the side of the clamping slot away from the ball head is provided with an opening, the pipeline is clamped into the clamping slot through the opening; openings are provided on both sides of the clamping slot.

[0005] The clamp supports and restrains the pipeline, while the ball joint structure frees the clamp to rotate freely, reducing the risk of pipeline twisting and damage and unusual noise during window raising and lowering. Furthermore, openings on both sides of the slot reduce the strength of the clamping joint, reducing the force required to squeeze the pipeline into the slot and facilitating installation.

[0006] In some embodiments, a groove wall of the card slot is provided with a protrusion, and the protrusion is arranged at both ends of the card slot in the length direction.

[0007] By setting a raised portion, the raised portion will press against the outer wall of the pipeline, causing a depression in the outer wall of the pipeline. The raised portion is clamped into the depression in the outer wall of the pipeline, which can limit the rotation and movement of the pipeline relative to the fixing clamp, thereby improving the firmness of the fixing clamp on the pipeline.

[0008] In some embodiments, the protrusion is strip-shaped and its extending direction is the same as the length direction of the slot.

[0009] By setting the protrusion to a strip shape and making its extension direction conform to the length direction of the slot, the limiting effect of the fixing clamp on the pipeline rotation can be improved. In addition, it is also convenient to ensure the quality of the injection molding of the protrusion and facilitate demolding of the protrusion after injection molding.

[0010] In some embodiments, the cross section of the protrusion is triangular, and a corner of the protrusion away from the slot wall is rounded.

[0011] By setting the cross section of the protrusion to a triangle and making the corner of the protrusion away from the groove wall rounded, on the one hand, the molding and demoulding of the protrusion are facilitated, and on the other hand, the damage to the pipeline caused by the corners of the protrusion can be reduced.

[0012] In some embodiments, guide portions are provided on both sides of the opening, and the guide portions are provided with guide slopes.

[0013] By providing the guide portion and the guide slope, the pipeline can be guided, making it easier for the pipeline to be inserted into the slot, thereby improving the installation efficiency of the pipeline.

[0014] In some embodiments, the cross-sectional dimensions of the two ends of the slot are smaller than the cross-sectional dimensions of the middle portion of the slot.

[0015] By designing the cross-sectional dimensions at both ends of the slot to be smaller than the cross-sectional dimensions of the middle part of the slot, that is, after the pipeline is inserted into the slot, the clamping force or wrapping force of the two ends of the slot on the pipeline is greater than that of the middle part of the slot, and the middle part of the slot may not even contact the outer wall of the pipeline. This can improve the firmness of the clamping part on the pipeline and reduce the risk of the pipeline falling out of the slot.

[0016] In some embodiments, an oil storage pit is provided on the surface of the ball head.

[0017] By providing an oil storage pit, the time that the lubricating oil remains on the ball head can be increased, thereby keeping the ball head lubricated for a long time, and making the connection between the ball head and the mounting groove smooth and without abnormal noise.

[0018] In some embodiments, the cross section of the connecting portion is cross-shaped.

[0019] By setting the cross section of the connection part to be cross-shaped, the weight of the connection part can be reduced, the material consumption can be reduced, and the purpose of lightweight design can be achieved compared to cylindrical or square column-shaped connection parts.

[0020] On the other hand, the present application provides a connection kit, including a mounting piece and the aforementioned fixing clip, wherein the mounting piece is provided with a mounting groove, and the ball head is suitable for being clamped in the mounting groove.

[0021] In some embodiments, a force unloading groove is provided at the notch of the installation groove, and the force unloading groove is communicated with the installation groove.

[0022] By providing the force unloading groove, the force required to press the ball head into the installation groove can be reduced, making it easier to press the ball head into the installation groove and improving the assembly efficiency of the ball head and the installation groove.

[0023] The present application provides a fixing clamp and a connection kit for clamping a pipeline, which has at least one of the following beneficial effects:

[0024] 1. This application provides a clamp for securing pipelines. The clamp supports and restrains the pipelines, while a ball-joint structure frees the clamp to rotate freely, reducing the risk of pipeline twisting and damage and unusual noise during window raising and lowering. Furthermore, openings on both sides of the clamping slot reduce the strength of the clamping joint, reducing the force required to squeeze the pipeline into the slot and facilitating installation.

[0025] 2. The present application provides a fixing clamp for clamping a pipeline. By setting a raised portion, the raised portion will press against the outer wall of the pipeline, causing a depression in the outer wall of the pipeline. The raised portion is clamped into the depression in the outer wall of the pipeline, which can limit the rotation and movement of the pipeline relative to the fixing clamp, and can improve the firmness of the fixing clamp on the pipeline.

[0026] 3. The present application provides a fixing clamp for clamping a pipeline. By setting the protrusion to a strip shape and making its extension direction conform to the length direction of the clamping slot, the fixing clamp can enhance the effect of restricting the rotation of the pipeline. In addition, it is also convenient to ensure the quality of the injection molding of the protrusion and facilitate the demolding of the protrusion after injection molding.

[0027] 4. The present application provides a fixing clamp for clamping pipelines.

[0042] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0043] To simplify the drawings, only the parts relevant to this application are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0044] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0045] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0046] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0047] refer to Figure 1-Figure 3The present application provides a fixing clamp for securing pipelines. The fixing clamp has a clamping portion 1 at one end and a ball head 2 at the other. The clamping portion 1 and the ball head 2 are connected by a connecting portion 3. The clamping portion 1 has a slot 4 for securing a pipeline 13. The slot 4 has an opening 5 on the side of the slot 4 away from the ball head 2. The pipeline 13 is inserted into the slot 4 through the opening 5. The ball head 2 can be inserted into the mounting groove 11 on the mounting member 14. When assembled, the ball head 2 and the mounting groove 11 form a ball-joint structure. It is easy to understand that the pipeline 13 referred to in this application is a plastic-coated structure, similar to a brake cable and a wire conduit wrapped around the outside of the brake cable. The pipeline 13 is encased in a steel wire or steel line that can move relative to the outer layer of the pipeline 13. In this embodiment, the fixing clamp is used to support and restrain the pipeline 13, and the ball-joint structure releases the clamp's freedom of movement, allowing the fixing clamp to rotate freely, reducing the risk of twisting and damage to the pipeline 13 and any abnormal noise during the window raising and lowering process.

[0048] refer to Figure 1 、 Figure 5 Preferably, openings 6 are provided on both sides of the slot 4. It is worth noting that the pipeline 13 is pressed into the slot 4. The pipeline 13 needs to expand the opening 5 during the process of being pressed into the slot 4. By providing openings 6 on both sides of the slot 4, the strength of the clamping part 1 can be reduced, and the force required to expand the opening 5 can be reduced, thereby facilitating the installation of the pipeline 13 into the slot 4. The opening 6 can be in the form of a strip, a circle, or a hollow, or other forms. It is preferably in the form of a strip, and the length direction of the opening 6 is substantially perpendicular to the pipeline 13. In other embodiments, the openings 6 may not be provided on both sides of the slot 4.

[0049] In this embodiment, there is no restriction on the cross-sectional form of the connecting portion 3. Figure 1 、 Figure 3 The connection part 3 can be in the form of a cylinder, a square column or a cross, or other forms. Figure 3 Preferably, the connection portion 3 is in the form of a cross, which can reduce the weight of the connection portion 3 and the material used compared to a cylindrical or square column-shaped connection portion 3, thereby achieving the purpose of lightweight design.

[0050] refer to Figure 1-Figure 3 In one embodiment, the slot 4 is provided with raised portions 7 on its wall, disposed at both ends of the slot 4 in the longitudinal direction. The raised portions 7 may be dot-shaped, sawtooth-shaped, or strip-shaped, or may be in other forms. It is readily understood that the raised portions 7 press against the outer wall of the pipeline 13, creating a depression in the outer wall of the pipeline 13. The raised portions 7 engage with the depression in the outer wall of the pipeline 13, thereby limiting the rotation and movement of the pipeline 13 relative to the retaining clamp, thereby enhancing the secure connection of the retaining clamp to the pipeline 13.

[0051] refer to Figure 1-Figure 3Preferably, the protrusion 7 is strip-shaped and its extension direction is the same as the length direction of the card slot 4. This can enhance the limiting effect of the fixing clamp on the rotation of the pipeline 13. It is also convenient to ensure the quality of the injection molding of the protrusion 7 and facilitate the demolding of the protrusion 7 after injection molding. The cross-sectional shape of the strip-shaped protrusion 7 can be triangular or cylindrical. It is preferably triangular, and the corner of the protrusion 7 away from the groove wall of the card slot 4 is rounded, that is, the corner of the protrusion 7 that is stuck in the outer wall of the pipeline 13 is rounded. This facilitates the molding and demolding of the protrusion 7 on the one hand, and reduces the damage to the pipeline 13 caused by the corners of the protrusion 7 on the other hand.

[0052] refer to Figure 1-Figure 3 In one embodiment, guide portions 8 are provided on both sides of the opening 5, and the guide portions 8 are provided with guide slopes 9. It is understood that the provision of the guide portions 8 and the guide slopes 9 can guide the pipeline 13, facilitate the insertion of the pipeline 13 into the slot 4, and improve the installation efficiency of the pipeline 13.

[0053] It is worth noting that the reference Figure 1 、 Figure 3 In one embodiment, the cross-sectional dimensions at the ends of the slot 4 are smaller than those in the middle of the slot 4. In other words, the depression in the middle of the slot 4 is greater than that at the ends, and the force used by the slot 4 to clamp the pipeline 13 is primarily provided by the ends. This means that after the pipeline 13 is inserted into the slot 4, the clamping force or wrapping force exerted by the ends of the slot 4 on the pipeline 13 is greater than that exerted by the middle of the slot 4. The middle of the slot 4 may not even contact the outer wall of the pipeline 13. This improves the secure connection between the clamping portion 1 and the pipeline 13 and reduces the risk of the pipeline 13 falling out of the slot 4.

[0054] It is easy to understand that in order to increase the time that the lubricating oil stays on the ball head 2, thereby maintaining the long-term lubrication of the ball head 2, refer to Figure 1-Figure 3 In one embodiment, an oil storage pit 10 is provided on the surface of the ball head 2. The oil storage pit 10 can store lubricating oil, so that the connection between the ball head 2 and the mounting groove 11 is smooth and without abnormal noise.

[0055] refer to Figure 4-Figure 6 The present application also provides a connection kit including a mounting member 14 and the aforementioned fixing clip. The mounting member 14 is provided with a mounting groove 11, and the ball head 2 is adapted to be clamped in the mounting groove 11. It is understood that the specific structure of the fixing clip refers to the aforementioned embodiment. Since the present connection kit adopts the technical solutions of the aforementioned embodiments, it at least has the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be described in detail here.

[0056] It is worth noting that the reference Figure 4-Figure 6In one embodiment, in order to facilitate pressing the ball head 2 into the mounting groove 11, a force unloading groove 12 can be provided at the notch of the mounting groove 11. The force unloading groove 12 is connected to the mounting groove 11. The force unloading groove 12 separates the notch edge of the mounting groove 11 by a full circle, so that the notch of the mounting groove 11 is stretched open when the ball head 2 is pressed into the mounting groove 11, thereby reducing the force required to press the ball head 2 into the mounting groove 11 and improving the assembly efficiency of the ball head 2 and the mounting groove 11.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
