Description

Technical Field

[0001] This utility model relates to the field of retractable data cables, and in particular to a retractable data cable with a small stroke adjustment. Background Technology

[0002] With the development of electronic devices, retractable data cables have emerged, greatly improving their storage and aesthetics. Existing retractable data cables generally have two states: unfolded and retracted.

[0003] However, the single-cell length adjustment of existing retractable data cables is generally more than 1cm. The adjustment of a single cell is mainly determined by the outer circumference of the inner diameter of the casing. Therefore, the smaller the outer circumference, the smaller the adjustable length.

[0004] For example, Chinese patent 202420851976.9 has a single-loop limit ring, which, through cooperation with a pawl, enables locking, unlocking, and automatic retraction during rotation. However, its adjustment range is still quite large, affecting the user experience. Utility Model Content

[0005] The main purpose of this invention is to propose a telescopic data cable with small stroke adjustment, which aims to improve the housing structure of existing telescopic data cables so that the turntable can achieve small stroke adjustment while ensuring its rotation stability and linearity.

[0006] To achieve the above objectives, this utility model proposes a retractable data cable with small stroke adjustment, comprising:

[0007] The housing has a receiving cavity;

[0008] A turntable, which is pivotally mounted in a receiving cavity, is provided with a partition that divides the turntable into an inner cavity and an outer cavity;

[0009] A torsion spring is provided in the inner cavity, with one end connected to the turntable and the other end connected to the housing. The torsion spring is used to apply a spring force to the turntable to wind up the data cable.

[0010] The upper wall of the turntable is recessed with a driving groove, which includes an inner sidewall and an outer sidewall. The inner sidewall is provided with at least two protruding ridges.

[0011] A guide structure is provided between the protruding ridge and the outer side wall; the guide structure and the inner side wall form a locking channel; and the guide structure and the outer side wall form an unlocking channel.

[0012] The guide structure includes a first arc-shaped portion and a second arc-shaped portion.

[0013] The inner side of the first arc-shaped portion is provided with a concave arc opposite to the convex edge.

[0014] The front end of the second arc-shaped portion extends to the rear part of the second arc-shaped portion and forms an insertion channel.

[0015] The rear end of the second arc-shaped section is provided with an exit channel;

[0016] A swing arm is provided in the housing. The swing arm is provided with a swing shaft that extends into the drive groove. The swing shaft is provided with a spring. The spring is used to drive the swing shaft to swing towards the outer wall.

[0017] In the actual design, the difference from the existing design is the use of multiple protruding ridges. This allows for multiple sets of guide structure intervals while ensuring a small stroke adjustment. The protruding ridges ensure adjustment in multiple states: 1. When locked, the swing shaft is engaged in the groove position; 2. When unlocking a single adjustment, the shaft moves from the insertion channel to the unlocking channel, and then back to the locking channel; 3. In the automatic retraction state, the swing shaft always participates in the unlocking channel until the end.

[0018] The use of convex ridges ensures the connection between the various guide structures.

[0019] The way the swing arm swings is the existing design. Attached Figure Description

[0037] like Figures 1 to 4 As shown, a retractable data cable with a small travel adjustment includes:

[0038] Housing 1, wherein housing 1 is provided with a receiving cavity 10;

[0039] Turntable 2 is pivotally mounted in receiving cavity 10. Turntable 2 is provided with partition 20, which is divided into inner cavity 21 and outer cavity 22.

[0040] Torsion spring 3, which is located in the inner cavity 21 and has one end connected to the turntable 2 and the other end connected to the housing 1, is used to apply a spring force to the turntable 2 to wind up the data cable;

[0041] The upper wall of the turntable 2 is recessed with a drive groove 4, the drive groove 4 including an inner sidewall 41 and an outer sidewall 42, the inner sidewall 41 being provided with at least two protruding ridges 8.

[0042] A guide structure is provided between the protruding ridge 8 and the outer side wall 42. The guide structure and the inner side wall 41 form a locking channel 51, and the guide structure and the outer side wall 42 form an unlocking channel 52.

[0043] The guide structure includes a first arc-shaped portion 6 and a second arc-shaped portion 7.

[0044] The inner side of the first arc-shaped portion 6 is provided with a concave arc opposite to the convex ridge 8.

[0045] The front end of the second arc-shaped portion 7 extends to the rear end of the second arc-shaped portion 7 and forms an insertion channel 53.

[0046] The rear end of the second arc-shaped portion 7 is provided with an exit channel 54;

[0047] A swing arm is provided in the housing 1. The swing arm is provided with a swing shaft 91 that extends into the drive groove 4. The swing shaft 91 is provided with a spring. The spring is used to drive the swing shaft 91 to swing in the direction of the outer wall 42.

[0048] In the actual design, the difference from the existing design is that multiple protruding ribs 8 are used, which can realize the setting of multiple sets of guide structure intervals while ensuring the adjustment of a small stroke. The setting of protruding ribs 8 ensures the adjustment of multiple states: 1. When locked, the swing shaft 91 is stuck in the groove 60.

[0049] 2. When unlocking a single adjustment, the shaft moves from the insertion channel 53 to the unlocking channel 52, and then through the insertion channel 53 into the locking channel 51 (the switching from the unlocking channel 52 to the insertion channel 53 to the locking channel 51 is mainly due to the fact that the diameter of the insertion channel 53 is greater than that of the unlocking channel 52 (and the pulling force of the hand), and the switching from the locking channel 51 to the exit channel 54 to the unlocking channel 52 is mainly due to the first slot 70 of the exit channel 54 and the elastic force of the spring, which causes the swing shaft 91 to switch, while the swing shaft 91 slides along the unlocking channel 52 under the elastic force of the torsion spring 3).

[0050] 3. In the automatic retraction state, the swing shaft 91 always participates in unlocking channel 52 until the end;

[0051] The use of convex rib 8 ensures the connection between various guide structures, while the swing arm's swing mechanism is an existing design.

[0052] Specifically, the convex ribs 8 are provided in four groups, with each group of guide structures arranged adjacent to each other. As shown in the figure, the standard spacing ensures that the telescopic distance of a section remains consistent, while its telescopic stroke is smaller.

[0053] In this embodiment of the invention, the outer wall of the first arc-shaped part 6 and the outer wall of the second arc-shaped part 7 extend in a counterclockwise arc shape, thereby ensuring that the swing shaft 91 can slide within the unlocking channel 52 during automatic retraction, thus achieving automatic unlocking.

[0054] Specifically, the front ends of the second arc-shaped portion 7 and the first arc-shaped portion 6 form an exit channel 54.

[0055] In this embodiment of the utility model, the rear end of the second arc-shaped portion 7 is provided with a recessed first groove 70, thereby realizing the switching from the locking channel 51 to the unlocking channel 52.

[0056] Specifically, the front end of the second arc-shaped portion 7 is tapered towards the axis and is sharp, thereby forming the insertion channel 53.

[0057] In this embodiment of the present invention, the first arc-shaped portion 6 is an elongated structure, and both ends of the first arc-shaped portion 6 are sharp.

[0058] Specifically, the inner sidewall 41 is located between the two protruding ridges 8 and is arc-shaped.

[0059] In this embodiment of the invention, the four protruding ridges 8 are arranged in a circumferential array along the axis, thereby ensuring consistent adjustment stroke.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
