Description

Technical Field

[0001] This utility model relates to the field of rotary bearing tail cap technology, and in particular to a rotary bearing tail cap. Background Technology

[0002] With the development of electronic technology and the progress of the times, screwdrivers are needed when repairing some small electronic devices. Since they are not easy to bear force, a rotary bearing cap is needed. This allows people to press the rotary bearing cap with their fingers to support the tail of the screwdriver, and then rotate the screwdriver to make it easy to remove the screw. Therefore, the rotary bearing cap plays a particularly important role.

[0003] In the use of existing rotary bearing tail caps, people generally press their fingers on the top of the cap and then use other fingers to rotate the screwdriver to disassemble the screws of electronic devices. However, when the fingers are pressed on the top of the rotary bearing tail cap, they are prone to slipping, which affects the efficiency of the cap in assisting the screwdriver to disassemble the device. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of existing rotary bearing tail caps, which, during use, require people to press their fingers on the top of the cap and then use other fingers to rotate the screwdriver to disassemble the screws of electronic devices. However, when the fingers are pressed on the top of the rotary bearing tail cap, they tend to slip, thus affecting the efficiency of the cap in assisting the screwdriver in disassembly. Therefore, this utility model proposes a rotary bearing tail cap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A swivel bearing end cap, comprising:

[0007] The tail cap body has an inner ring installed on its inner side, and a ball bearing is movably arranged between the inner ring and the tail cap body. The inner ring has a threaded groove on its inner side, and reserved holes are opened on both sides of the bottom of the inner ring. A fixing groove is opened on one side of the top of the tail cap body, and a movable plate is installed on the other side of the top of the tail cap body. The movable plate is connected to the tail cap body through a damping shaft.

[0008] Preferably, the inner ring forms a movable structure with the tail cap body via ball bearings.

[0009] Preferably, the threaded groove forms an integrated structure with the inner ring through slotting.

[0010] Preferably, the movable plate has an arc-shaped structure, and the movable plate forms a rotating structure with the tail cap body through a damping pivot.

[0011] Preferably, the inner side of the movable plate has a slot that is the same as the fixed slot.

[0012] Preferably, the inner side of the movable plate has a semi-grooved structure, and the fixing groove has a semi-grooved structure.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up the movable plate, damping shaft, and tail cap body, when using the rotary bearing tail cap, people can press their fingers into the fixing groove on the top of the tail cap body and the slot in the movable plate, thereby increasing the friction between the fingers and the rotary bearing tail cap, making it less likely to fall off. Furthermore, the movable plate can be rotated around the damping shaft, causing it to rotate 180° away from the fixing groove and re-fit against the tail cap body. This allows people to place the center of their palm against the surface of the tail cap body and the movable plate, facilitating the rotation of the screwdriver by other fingers and assisting in the assembly and disassembly of screws in electronic components.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3A rotary bearing tail cap includes a tail cap body 1, an inner ring 2 mounted on the inner side of the tail cap body 1, and a ball bearing 3 movably disposed between the inner ring 2 and the tail cap body 1. A threaded groove 4 is formed on the inner side of the inner ring 2, and pre-drilled holes 5 are formed on both sides of the bottom of the inner ring 2. The inner ring 2 and the tail cap body 1 form a movable structure through the ball bearing 3. When a screwdriver connected to the inner ring 2 is used for screw removal, the screwdriver can be rotated, causing the inner ring 2 to slide along the outer wall of the ball bearing 3, thus facilitating smoother screw removal. The threaded groove 4... The inner ring 2 and the slotted inner ring 2 form an integrated structure. The inner ring 2 is connected to the screwdriver output end via a threaded groove 4, completing the connection between the inner ring 2 and the screwdriver. A fixing groove 6 is provided on one side of the top of the tail cap body 1, and a movable plate 7 is installed on the other side of the top of the tail cap body 1. The movable plate 7 is connected to the tail cap body 1 via a damping shaft 8. The movable plate 7 has an arc-shaped structure and forms a rotating structure with the tail cap body 1 via the damping shaft 8. By rotating the movable plate 7, it can present two states. When the contact area between the movable plate 7 and the tail cap body 1 is large, the semi-groove on the inner side of the movable plate 7 and the fixing groove 6 of the semi-groove structure combine to form a larger groove structure, making it convenient for people to press their fingers on the top of the tail cap body 1 to assist in the screwdriver's work of removing screws. Similarly, after manually rotating the movable plate 7, under the action of the damping shaft 8, it has high stability with the tail cap body 1 and will not automatically return to its original position, allowing people to place the center area of ​​their palm against the surface of the movable plate 7, while the rest of their palm can rest against the surface of the tail cap body 1, and then... The user's fingers are used to manipulate the screwdriver, assisting in the installation and removal of screws. The inner side of the movable plate 7 has a slot that is identical to the fixed groove 6. By having the same slot, the movable plate 7 is in its initial state, and the slot and the fixed groove 6 are perfectly aligned. When a user presses their fingers into the slot, they can better press the tail cap body 1. The inner side of the movable plate 7 has a semi-recessed structure, and the fixed groove 6 has a semi-recessed structure. Together, they form a large groove, making it convenient for users to press their fingers.

[0022] Working principle: In use, the operator first connects the output end of the screwdriver used for repairing small electronic devices to the threaded groove 4, thus connecting the screwdriver to the inner ring 2. When using the screwdriver, the operator can press their fingers into the fixed groove 6 of the semi-recessed structure on the top of the tail cap body 1 and the slot on the movable plate 7. This allows the two semi-recessed structures to form a larger groove, increasing the friction between the fingers and the rotating bearing tail cap, making it less likely to fall off. The movable plate 7 can also be rotated around the damping shaft 8, rotating 180° away from the fixed groove 6 and re-fitting with the tail cap body 1. Under the action of the damping shaft 8, the movable plate 7 has high stability with the tail cap body 1 and will not automatically reset. The operator can then place their palm against the surface of the tail cap body 1 and the movable plate 7, allowing other fingers to rotate the screwdriver and assist in the assembly and disassembly of electronic components.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
