Abstract
Description
Technical Field
[0001] This utility model relates to the field of telescopic tube technology, and in particular to an anti-jamming structure for spring clips. Background Technology
[0002] Conventional telescopic tubes often employ a spring clip in the inner tube, with the protruding end of the spring clip able to pop out freely from a hole in the inner tube. The outer tube has two or more holes so that after the inner and outer tubes are pulled relative to each other, the protruding end of the spring clip pops out from the hole in the outer tube to position the inner and outer tubes.
[0003] However, during the telescopic positioning of the inner and outer tubes, the spring clip often gets stuck in the hole of the inner tube and cannot pop out freely, resulting in the inability to effectively telescopically fix the inner and outer tubes. Summary of the Invention
[0004] This disclosure provides an anti-jamming structure for spring clips, which at least solves the technical problem in the prior art where spring clips get stuck in the hole of the inner tube, resulting in ineffective extension and retraction.
[0005] The present invention solves the above problems by adopting the following technical solution: An anti-jamming structure for a spring clip includes an inner tube and an outer tube that are telescopic to each other. The outer tube has at least two first holes on its wall. The inner tube has at least one spring clip and at least one second hole on its wall. The spring clip includes a push-out end that can pop out of the second hole in the inner tube. The inner tube is also provided with a limiting structure, which is set at the pre-movement direction position after the ejector end is pressed down, to prevent the ejector end from being pressed down into the second hole of the inner tube and getting stuck.
[0006] In the aforementioned anti-jamming structure for the spring clip, there are two second holes; there are also two ejector ends of the spring clip, and one ejector end can eject from one of the second holes.
[0007] In the aforementioned anti-jamming structure for the spring clip, the limiting structure includes a fixing part and a limiting part. The fixing part is fixed to the inner wall of the inner tube, and the limiting part is connected to the fixing part. The limiting part is positioned in the pre-movement direction when the ejector end is pressed down and retracted, to prevent the ejector end from being pressed down into the second hole of the inner tube and jamming.
[0008] In the aforementioned anti-jamming structure for the spring clip, the fixing part is in the shape of a cylinder or a cylindrical shape, and is fixed to the inner wall of the inner tube by means of the cylinder or cylindrical shape; The limiting part is directly connected to the circular end face of the cylinder, or connected to the opening at one end of the cylinder through a connector.
[0009] In the aforementioned anti-jamming structure for the spring clip, the limiting portion extends away from the circular end face of the cylinder, or extends away from the connector.
[0010] In the aforementioned anti-jamming structure for the spring clip, the connecting member is a circular sheet, which is fixed at one end opening of the cylinder, and the limiting part is fixed on the circular sheet.
[0011] In the aforementioned anti-jamming structure for the spring clip, the spring clip includes a main body and an ejector end; wherein the main body is curved in an arc shape, and its shape is V-shaped or U-shaped.
[0012] In the aforementioned anti-jamming structure for the spring clip, the fixing part is a skeleton structure, which is fixed to the inner wall of the inner tube, and the limiting part is fixed to the skeleton structure.
[0013] In the aforementioned anti-jamming structure for the spring clip, the limiting structure is a protruding structure located at the bottom of the ejector end.
[0014] In the aforementioned anti-jamming structure for the spring clip, the outward protrusion direction of the protruding structure is toward the axis of the inner tube, and the protruding structure is located on one side of the spring clip of the spring clip, while the ejector end is located on the other side of the spring clip of the spring clip.
[0015] In the aforementioned anti-jamming structure for the spring clip, the limiting structure limits the ejector end to a size such that the end of the ejector end is flush with the wall of the inner tube.
[0016] Once the ejector end is flush with the wall of the inner tube, the limiting part limits the ejector end, preventing it from being pressed downwards and ensuring that the ejector end is not stuck in the hole of the inner tube.
[0017] In the aforementioned anti-jamming structure for the spring clip, the material of the protruding structure is the same as the material of the spring clip.
[0018] The anti-jamming structure for the spring clip of this utility model can effectively prevent the ejector end from getting stuck inside the inner tube wall through the limiting structure, thereby solving the technical defect that the inner and outer tubes cannot be positioned due to the spring clip getting stuck and unable to eject after being pressed down.

[0023] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0024] The following describes, with reference to the accompanying drawings, an anti-jamming structure for a spring clip provided in an embodiment of this application.
[0025] like Figure 1 , Figure 3 As shown, this application provides an anti-jamming structure for a spring clip, including an inner tube 1 and an outer tube 2 that are telescopic to each other. The outer tube 2 has at least two first holes 3 on its wall. The inner tube 1 has at least one spring clip 4 and at least one second hole 5 on its wall. The spring clip 4 includes a push-out end 6 that can pop out of the second hole 5 of the inner tube 1. It should be noted that the first hole 3 provided on the wall of the outer tube 2 should include at least two holes at different heights, which are used to pop out corresponding to the ejected end 6 in the inner tube 1, and to adjust the length between the inner tube 1 and the outer tube 2.
[0026] The inner tube 1 is also provided with a limiting structure 7, which is located in the pre-movement direction position after the ejector end 6 is pressed down, to prevent the ejector end 6 from being pressed down into the hole of the inner tube 1 and getting stuck.
[0027] The spring clip 4 includes a main body 9 and an ejector end 6; wherein, the main body 9 is curved in an arc shape, either V-shaped or U-shaped. The main body 9 can be made of a V-shaped or U-shaped metal spring, and the metal can be any one of manganese steel, brass, beryllium copper, SUS301, or stainless steel.
[0028] The inner tube 1 is provided with a spring clip 4. The protruding end 6 of the spring clip 4 is ejected from the second hole 5 on the tube wall of the inner tube 1 by means of the elastic force provided by the main structure of the spring clip 4. After the extension and retraction adjustment, when one of the two first holes 3 on the tube wall of the outer tube 2 is aligned with the protruding end 6, the protruding end 6 can be ejected to fix the inner tube 1 and the outer tube 2.
[0029] However, in actual use, the ejector end 6 of the spring clip 4 is often pressed too much and gets stuck in the inner wall of the inner tube 1. Due to the obstruction of the inner tube 1 wall, it cannot pop out of the hole of the inner tube 1, thus failing to achieve the effect of fixing the inner tube 1 and the outer tube 2.
[0030] By implementing the above technical solution, the limiting structure 7 can prevent the top end 6 of the snap button 4 from being pressed excessively, thereby solving the jamming problem.
[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the limiting structure 7 includes a fixing part 701 and a limiting part 702, wherein the fixing part 701 is fixed to the inner wall of the inner tube 1, and the limiting part 702 is connected to the fixing part 701; and the limiting part 702 is set at the pre-movement direction position when the ejector end 6 is pressed down and retracted, to prevent the ejector end 6 from being pressed down into the hole of the inner tube 1 and getting stuck.
[0032] The limiting part 702 is effectively fixed in the inner tube 1 by the fixing part 701. The limiting part 702 is located in the direction of movement of the ejector end 6 during the pressing process, thereby effectively preventing the ejector end 6 from being excessively pressed down.
[0033] like Figure 2 As shown, in some embodiments, the fixing part 701 is cylindrical and is fixed to the inner wall of the inner tube 1 by means of the cylinder; the limiting part 702 is directly connected to the circular end face of the cylinder.
[0034] Please refer to Figure 1The fixing part 701 is cylindrical in shape, which fits the shape of the inner tube 1, and can be effectively embedded in the inner tube 1 and thus fixed in the inner tube 1. The limiting part 702 is connected to the end face of the cylinder and extends toward the opening of the spring buckle 4 to prevent the ejector end 6 from being excessively pressed down.
[0035] In some embodiments, the limiting portion 702 extends toward the circular end face away from the cylinder.
[0036] It should be noted that the shape of the fixing part 701 can also be square, hexagonal, or octagonal, as long as it is used to fix to the inner wall of the inner tube 1, it is the inventive concept of this application.
[0037] In some embodiments, the fixing part 701 is cylindrical (not shown in the figure) and is fixed to the inner wall of the inner tube 1 by means of the cylinder; the limiting part 702 is connected to the opening at one end of the cylinder by means of a connector (not shown in the figure).
[0038] Whether it is a cylinder or a tubular tube, it is for fixing to the inner wall of the inner tube 1. The limiting part 702 is inserted into the opening of the spring buckle 4 to prevent the ejector end 6 from being excessively pressed down.
[0039] In some embodiments, the limiting portion 702 extends away from the connector in a direction that is pressed toward the protruding end 6 of the snap 4.
[0040] In some embodiments, the connector is a circular sheet fixed at one end opening of the cylinder, and the limiting part 702 is fixed on the circular sheet.
[0041] In some embodiments, the fixing part 701 is a skeleton structure (not shown in the figure), which is fixed to the inner wall of the inner tube 1. The limiting part 702 is fixed to the skeleton structure. The limiting part 702 extends toward the opening of the snap 4 to prevent the ejector end 6 from being excessively pressed down.
[0042] It should be noted that the skeleton structure is made of woven metal wire and is used to support the structure of the limiting part 702.
[0043] In some embodiments, the limiting structure 7 can also be integrally connected with the spring buckle 4, such as... Figure 4 As shown, the limiting structure 7 is a protruding structure 8 disposed at the bottom of the ejector end 6. The outward protrusion direction of the protruding structure 8 is opposite to the extension direction of the ejector end 6, and the protruding structure 8 is located on one side of the spring piece of the snap 4, while the ejector end 6 is located on the other side of the spring piece of the snap 4.
[0044] In some embodiments, the material of the protruding structure 8 is the same as the material of the spring buckle 4.
[0045] In some embodiments, the limiting structure 7 limits the ejector end 6 by making the end of the ejector end 6 flush with the wall of the inner tube 1.
[0046] In some embodiments, the limiting structure may also be a guide tube structure extending from the second hole 5 of the inner tube into the interior of the inner tube. The guide tube structure may be formed by punching the second hole. Since the guide tube has a wall extending from the second hole into the interior of the inner tube, it forms a limiting wall surface for the ejector end 6, preventing the ejector end 6 from being pressed into the tube wall of the inner tube and getting stuck.
[0047] The anti-jamming structure for the spring clip of this utility model can effectively prevent the ejector end 6 from jamming inside the inner tube 1 through the limiting structure 7, thereby solving the technical defect that the inner tube 1 and outer tube 2 cannot be effectively positioned due to the spring clip 4 being jammed after being pressed down and unable to pop out.
[0048] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
