Description

Technical Field

[0001] The utility model relates to the technical field of data line devices, in particular to a retractable data line device. Background Art

[0002] Because ordinary data cables are generally long and inconvenient to carry, they are easily entangled when placed directly on the table or in a bag, causing inconvenience to the user. For this reason, people have invented various retractable data cables, which are wound by setting a spring in the main part to cooperate with the wheel core to achieve the effect of being more compact and anti-entanglement. When the data cable is stored, it is only necessary to pull the data cable for a certain length and then release it. Under the action of the spring, the wheel core will be driven to rotate, so that the data cable is wound on the wheel core to achieve the function of winding. However, when the spring drives the wheel core to rotate, the rotation speed of the wheel core will become faster and faster, which may cause the data cable to hit the user. For this reason, people have invented a retractable data cable that can have a damping effect on the rotation process of the wheel core, such as the retractable data cable structure disclosed in the Chinese utility model patent CN215418847U, which increases the resistance of the winding disc when rotating by setting an elastic damping mechanism on one side of the shell, and the elastic damping end and the winding disc (i.e., the wheel core) increase the resistance when the winding disc rotates, which can effectively reduce the rotation speed of the winding disc when winding, thereby avoiding the winding speed from hitting people too fast. However, this type of retractable data cable has the following problems: first, the elastic damping mechanism rubs against the cable winding reel for a long time, causing wear on both; second, the elastic damping mechanism protrudes from the outside of the shell, causing the entire product structure to be unsophisticated and unsightly; third, the elastic damping mechanism rubs against the cable winding reel, causing a harsh friction sound, causing discomfort to the user. Utility Model Content

[0003] In view of the defects of the prior art, the utility model provides a retractable data cable device with a damping wheel core which has a simpler structure, a more reasonable design, will not wear the wheel core, will not emit harsh friction noise, can slow down the rotation speed of the wheel core, and has a decompression effect.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a retractable data cable device with a damping wheel core, comprising a shell, a wheel core and a damping mechanism, the wheel core is movably installed in the shell to form a rotatable structure, the damping mechanism is docked with the wheel core, and is characterized in that: the damping mechanism comprises a marble and a plurality of damping grooves, the two are arranged between the shell and the wheel core and located in the shell, the marbles are opposite to the damping grooves; the marbles are connected to an elastic component, and when the wheel core rotates, the elastic component drives the marbles to be stuck in different damping grooves to form a damping and sound-generating structure for the wheel core.

[0005] Furthermore, the damping mechanism includes a damping wheel, a damping groove is arranged on the damping wheel, and the marble is connected to the damping groove on the damping wheel from the side.

[0006] Further, the damping wheel is installed in the housing to form a fixed structure, and the marbles are installed on the wheel core in cooperation with the elastic components to form a structure that rotates synchronously with the wheel core.

[0007] Alternatively, the damping wheel is installed on the wheel core to form a structure that rotates synchronously with the wheel core, and the marbles are installed on the housing in cooperation with the elastic components to form a fixed structure.

[0008] Further, a partition strip is provided on the wheel core, and an accommodation groove and a mounting groove are formed by surrounding the partition strip; the wheel core is installed on the shaft tube at the center of the housing to form a rotatable structure, the damping wheel is fixed to the top of the shaft tube by screws and embedded in the accommodation groove on the wheel core; the marbles and the elastic components are installed in the mounting groove together, and the marbles protrude from the mounting groove and are docked with the damping grooves of the damping wheel.

[0009] Further, the elastic component is a spring, the marble abuts against the head end of the spring, and the spring presses the marble into the damping groove; a fixed head is provided in the mounting groove, and the tail end of the spring is inserted into the fixed head.

[0010] Further, a baffle extending outward is provided at the top edge of the damping wheel, and the baffle is located at the top of the damping groove to block the marbles.

[0011] Further, the damping grooves are wavy arc grooves uniformly arranged on the outer circumferential surface of the damping wheel. As the data cable is pulled out or retracted, the marbles will continuously press into the damping grooves, which can not only achieve the damping effect on the wheel core but also emit a rhythmic "click, click, click" sound, having a certain decompression effect.

[0012] Further, the housing includes an upper housing and a lower housing, the shaft tube is located at the center of the lower housing, and the upper housing covers the damping wheel. A limiting and guiding structure is also provided between the upper housing and the wheel core, which of course belongs to the prior art.

[0013] By providing a damping mechanism in which the damping grooves cooperate with the marbles between the housing and the wheel core, the utility model can not only slow down the rotation speed of the wheel core and prevent the data cable from hurting people. At the same time, because a non-frictional damping process is adopted between the damping mechanism and the wheel core, the wear of the wheel core can be avoided, and a rhythmic and decompression-effect sound will be emitted, and no harsh frictional sound will occur, so it has a better user experience.

Specific implementation mode

[0020] In this embodiment, referring to Figures 1 - 5 , the telescopic data cable device with a damping wheel core includes a housing, a wheel core 2 and a damping mechanism 3. The wheel core 2 is movably installed in the housing to form a rotatable structure, and the damping mechanism 3 is docked with the wheel core 2; the damping mechanism 3 includes a ball 4 and a plurality of damping grooves 33, which are arranged between the housing and the wheel core 2 and are located inside the housing (will not protrude outside the housing), and the ball 4 is opposite to the damping grooves 33; the ball 4 is connected with an elastic component, and when the wheel core 2 rotates, the elastic component drives the ball 4 to be stuck in different damping grooves 33 to form a damping and sound-generating structure for the wheel core 2.

[0021] The damping mechanism 3 includes a damping wheel 31, and the damping grooves 33 are arranged on the damping wheel 31, and the ball 4 is docked with the damping grooves 33 on the damping wheel 31 from the side.

[0022] The damping wheel 31 is installed in the housing to form a fixed structure, that is, the damping wheel 31 will not rotate, and the ball 4 is installed on the wheel core 2 in cooperation with the elastic component to form a structure that rotates synchronously with the wheel core 2.

[0023] Or adopt another implementation mode, that is, the damping wheel 31 can also be installed on the wheel core 2 to form a structure that rotates synchronously with the wheel core 2, and the ball 4 is installed on the housing in cooperation with the elastic component to form a fixed structure. The two methods have basically equivalent effects.

[0024] A partition strip 23 is arranged on the wheel core 2, and an accommodating groove 21 and an installation groove 22 are formed by surrounding the partition strip 23; the wheel core 2 is installed on the shaft tube 13 at the center of the housing to form a rotatable structure, and the damping wheel 31 is fixed to the top of the shaft tube 13 by screws and embedded in the accommodating groove 21 on the wheel core 2; the ball 4 and the elastic component are installed in the installation groove 22 together, and the ball 4 protrudes from the installation groove 22 to be docked with the damping grooves 33 of the damping wheel 31.

[0025] The elastic component is a spring 5, and the marble 4 is pressed against the head end of the spring 5, and the spring 5 presses the marble 4 into the damping groove 33; a fixing head 24 is arranged in the installation groove 22, and the tail end of the spring 5 is plugged into the fixing head 24. Since the elastic potential energy of the mainspring of the driving wheel core 2 is greater than the force of the spring 5 on the marble 4 to press the damping wheel 31, when the data cable is slowly released, the spring 5 drives the marble 4 to press into the damping groove 33, which can only decelerate the wheel core 2, and will not prevent the rotation of the wheel core 2.

[0026] A rib 32 extending outward is provided at the top edge of the damping wheel 31 , and the rib 32 is located at the top of the damping groove 33 to block the marble 4 and prevent the marble 4 from escaping from the damping groove 33 .

[0027] The damping groove 33 is a wavy arc groove evenly arranged on the outer circumference of the damping wheel 31. As the data cable is pulled out or retracted, the marbles 4 will be continuously pressed into the damping groove 33, which will not only have a damping effect on the wheel core 2, but also emit a rhythmic "da, da, da" sound, which has a certain decompression effect.

[0028] The housing includes an upper shell 11 and a lower shell 12, the shaft tube 13 is located at the center of the lower shell 12, and the upper shell 11 covers the damping wheel 31. A limited position guide structure is also provided between the upper shell 11 and the wheel core 2, which is used to control the wheel core 2 to stop rotating and realize the positioning of the data cable after being pulled out. Of course, this belongs to the prior art, and its specific structure is not described here.

[0029] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
