Description

Technical Field

[0001] The utility model relates to a telescopic cable, in particular to a freely stretchable, locking and telescopic charging data cable. Background Art

[0002] With the popularity of electronic devices and household appliances, more and more devices need to use retractable cables to achieve power or signal connection. The retractable cable can be stretched when in use and retracted when not in use, which greatly improves the convenience of use and the neatness of the device. However, there are some problems with the existing retractable cables during use. The locking mechanism of the existing retractable cables is usually complicated and prone to jamming or failure, making it difficult for users to stretch and retract the retractable cables.

[0003] In the prior art, common retractable wire devices include basic structures such as a wire reel, a housing, and an elastic member. The wire reel is used to coil the wire, the housing is used to accommodate the wire reel and other components, and the elastic member is used to provide power to recycle the wire. However, the locking mechanism of these devices usually adopts a complex gear or buckle structure, which is easy to get stuck or lock loosely due to wear or dirt, affecting the service life and user experience.

[0004] For example, existing retractable wire devices usually use a gear locking mechanism. When the wire is pulled out, the gear and buckle cooperate to fix the wire reel in a specific position. However, the gears and buckles of this structure are easy to wear, resulting in loose locking or difficulty in resetting. In addition, the gear and buckle structure is relatively complex, the manufacturing cost is high, and the installation and maintenance are inconvenient. Users often need to manually operate the buckle to lock and unlock during use, which is not convenient enough. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a freely stretchable, locking and retractable charging data cable, which can effectively solve the deficiencies in the prior art.

[0006] The utility model is realized by the following technical scheme: a freely stretchable, locking and retractable charging data cable, comprising:

[0007] A housing, wherein a wire drum is installed in the housing, a wire is wound on the wire drum, a wire outlet is provided on the housing, one end of the wire extends out of the wire outlet, and the wire drum is elastically connected to the housing through an elastic spring;

[0008] A lock tongue is rotatably mounted in the housing, and a plurality of locking grooves are arranged on the wire drum around the wire drum. When the lock buckle of the lock tongue is buckled into one of the locking grooves, the wire drum is in a locked state, and the lock tongue is linked to the pulling action;

[0009] A locking connector having a first end and a second end, wherein the first end is connected to the locking tongue, and the second end is movably disposed in a track groove of a track plate, and a loosening or locking action of the cable drum is achieved by changing the position of the second end in the track groove;

[0010] An elastic part used to automatically return the lock tongue to its original position when there is no additional pressure.

[0011] As a preferred technical solution, a limiting portion is provided in the track groove, and a limiting groove is provided on the limiting portion. When the second end is located in the limiting groove, the lock buckle is buckled into one of the locking grooves.

[0012] As a preferred technical solution, a plurality of track points are formed in the track groove, namely a first track point A, a second track point B, a third track point C, and a fourth track point D;

[0013] When the wire is pulled out, the second end of the locking connector moves from the first track point A to the second track point B. Under the elastic force of the elastic member, the second end moves from the second track point B to the third track point C, and the third track point C limits the second end.

[0014] When the wire is pulled again, the second end moves from the third track point C to the fourth track point D, and is then elastically reset by the elastic member, and the second end is reset from the fourth track point D to the first track point A.

[0015] As a preferred technical solution, the limit groove has a V-shaped limit clamp with an angle greater than 90 degrees, which has a track guidance function and can guide one end of the locking connector to move in a specified direction to achieve the purpose of one locking and one opening.

[0016] As a preferred technical solution, a fixing hole is provided on the locking tongue, and the first end of the locking connector is buckled into the fixing hole.

[0017] As a preferred technical solution, the elastic member adopts an elastic connecting piece, and the elastic connecting piece is used to elastically reset the lock tongue. The elastic member has an arc-shaped wrapping portion, and the arc-shaped wrapping portion wraps the arc-shaped rotating surface of the lock tongue.

[0018] As a preferred technical solution, a hinge hole is further provided on the lock tongue, and the lock tongue is hingedly mounted on a hinge shaft inside the shell through the hinge hole.

[0019] The beneficial effects of the utility model are as follows: the utility model provides a retractable cable solution with easy operation and reliable locking by improving the structure of the free-stretching and locking retractable charging data cable;

[0020] First, the wire reel and lock tongue inside the housing cooperate to realize the free stretching and locking of the wire. When the wire is pulled out, the lock of the lock tongue automatically buckles into the locking groove on the wire reel to ensure that the wire reel is in a locked state, effectively preventing the wire from retracting. Secondly, the design of the locking connector and track plate enables the locking connector to slide in the track groove, and the locking and release of the wire reel are controlled by position changes, which greatly simplifies the operation process;

[0021] At the same time, the setting of the elastic member ensures the reset ability of the lock tongue, so that the lock tongue can always maintain good elasticity and locking effect during use. The overall structure is simple and the design is reasonable, which effectively improves the durability and service life of the device, avoids the common problems of jamming and loose locking in the prior art, and the user does not need to frequently operate manually during use, and the use experience is more convenient and comfortable.

[0031] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0032] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] like Figure 1 As shown, the utility model is a free stretch locking telescopic charging data cable, comprising a housing 1, a cable drum 3 is installed in the housing 1, a wire is coiled on the cable drum 3, a cable outlet 2 is provided on the housing 1, one end of the wire 100 extends out of the cable outlet 2, the cable drum 3 is elastically connected to the housing 1 through an elastic spring, the cable mentioned here can be a data cable or a charging cable, and the utility model can be a charger and other products;

[0034] like Figure 2 As shown, it also includes a lock tongue 6, which is rotatably installed in the housing 1. A plurality of locking grooves 11 are arranged around the wire drum 3. When the lock buckle 9 of the lock tongue 6 is buckled into one of the locking grooves 11, the wire drum 3 is in a locked state. The lock tongue 6 is linked with the pulling action. When the wire is pulled, the wire drum 3 rotates, and the rotation of the wire drum 3 drives the lock tongue 6 to rotate along the hinged end. When the lock buckle 9 is buckled into the locking groove 11, the wire drum 3 cannot rotate at this time, thereby achieving the purpose of locking the wire drum 3.

[0035] Please continue reading Figure 2 , further comprising a locking connector 10, which has a first end 101 and a second end 102, wherein the first end 101 is connected to the locking tongue 6, and the second end 102 is movably disposed in a track groove 15 of a track plate 14, and the loosening or locking action of the wire drum 3 is achieved by changing the position of the second end 102 in the track groove 15;

[0036] In this embodiment, an elastic member is further included, which is fixed on the outside of the locking tongue 6. The locking tongue 6 is located in the middle of the elastic member, and the two sides of the locking tongue 6 are elastically limited by the elastic member. When the locking tongue 6 rotates along the hinged end, the elastic member will undergo elastic deformation. The elastic member serves as the elastic reset of the locking tongue 6, so that the lock buckle 9 is buckled into the locking groove 11, thereby achieving the purpose of locking the wire.

[0037] like Figure 3 As shown, a limiting portion 13 is provided in the track groove 15, and a limiting groove 12 is provided on the limiting portion 13. When the second end 102 is located in the limiting groove 12, the lock buckle 9 is buckled into one of the locking grooves 11. When the second end 102 moves to the position, it is reset by the elastic member. At this time, the second end of the locking connector 10 can fall into the limiting groove 12. Figure 5 As shown, at this time, the lock buckle 9 at the position of the lock tongue 6 is just buckled into the locking groove 11, the wire drum 3 cannot rotate at this time, and the wire cannot be retracted. At this time, the pulled wire can be used.

[0038] like Figure 3 As shown, a plurality of track points are formed in the track groove 15, namely, a first track point A, a second track point B, a third track point C, and a fourth track point D;

[0039] When the wire is pulled out, the second end 102 of the locking connector 10 is displaced from the first track point A to the second track point B. Under the elastic force of the elastic member, the second end 102 is displaced from the second track point B to the third track point C. The third track point C limits the second end 102.

[0040] When the wire is pulled again, the second end 102 moves from the third track point C to the fourth track point D, and is then elastically restored by the elastic member. At this time, the second end 102 is restored from the fourth track point D to the first track point A.

[0041] The whole action process is as follows: in the reset state, the second end 102 of the locking connector 10 is located at the first track point A. Figure 6 As shown, at this time, the wire is pulled out to the required height. At this time, the pulling action causes the wire drum 3 to rotate, and the rotation of the wire drum 3 drives the locking tongue 6 to rotate. After the locking tongue 6 rotates, the lock buckle 9 is separated from the locking groove 11. When the locking tongue 6 is pulled, the locking connector 10 follows the movement, and the second end 102 of the locking connector 10 reaches the second track point B from the first track point A. After the wire is released, the elastic member resets the locking tongue 6. At this time, the second end 102 of the locking connector 10 is buckled into the third track point C. The extended wire can be used at this time. When the wire needs to be retracted, it is only necessary to pull the wire again. At this time, the locking tongue 6 rotates, and the second end 102 of the locking connector 10 is separated from the second track point B and enters the fourth track point D. Figure 4As shown, the second end 102 of the wire locking connector 10 is then released and reset from the fourth track point D to the first track point A. The entire track path is as shown in FIG. Figure 3 As shown, one path is a process of using the wire once.

[0042] In this embodiment, Figure 3 As shown, the limit groove 12 has a V-shaped limit clamp, and its angle is greater than 90 degrees, which facilitates the second end 102 to be snapped into the limit groove 12. The angle has a track guide and can guide one end of the locking connector to move in a specified direction to achieve the purpose of one locking and one opening.

[0043] In order to realize the linkage between the locking tongue 6 and the locking connector 10 , in this embodiment, a fixing hole 5 is provided on the locking tongue 6 , and the first end 101 of the locking connector 10 is buckled into the fixing hole 5 .

[0044] In this embodiment, the elastic member adopts an elastic connecting piece, and elastic extension pieces 4 are formed on both sides of the elastic member respectively. The elastic extension pieces 4 are located on both sides of the lock tongue 6. The elastic member has an arc-shaped wrapping portion 8, and the arc-shaped wrapping portion 8 wraps the arc-shaped rotating surface of the lock tongue 6. No matter which side the lock tongue 6 rotates to, the elastic connecting piece can be elastically deformed, and then the elastic deformation force is used to reset the lock tongue 6, so that the locking connecting piece 10 can move in the track groove 15.

[0045] The locking tongue 6 is also provided with a hinge hole 7 , and the locking tongue 6 is hingedly mounted on a hinge shaft inside the housing 1 through the hinge hole 7 .

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
