Description

Technical Field

[0001] This utility model belongs to the field of sleeve technology, specifically relating to an adjustable guide sleeve. Background Technology

[0002] Currently, most guide sleeves on the market use a sliding edge on the hexagonal hole of the sleeve to allow the nut or bolt to smoothly engage with the guide sleeve under the guidance of the sliding edge, thus making it easier for users to tighten the bolt or nut. For example, a guide sleeve for a wrench is disclosed in Chinese Patent Publication No. CN208681445U. However, since the length of the sleeve cannot be adjusted according to different usage needs, users need to prepare a variety of different sleeves when performing disassembly and assembly operations. These sleeves are not only heavy, but also take up a lot of storage space. In addition, sleeves of different sizes and lengths are not easy to organize and store. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 10As shown, an adjustable guide sleeve includes a sleeve body 1, a first cylinder 2 attached to the surface of the sleeve body 1, a threaded cylinder 3 fixedly connected to the inner wall of the first cylinder 2, a top cover 4 fixedly connected to the surface of the threaded cylinder 3, a connector 5 fixedly connected to the upper surface of the top cover 4, a connecting post 6 fixedly connected to the upper surface of the sleeve body 1, a locking plate 7 fixedly connected to the upper surface of the connecting post 6, sliding holes 8 on both the left and right sides of the threaded cylinder 3, a threaded ring 9 threadedly connected to the surface of the threaded cylinder 3, U-shaped posts 10 attached to both the left and right sides of the threaded ring 9 and the inner wall of the sliding holes 8, a column 11 fixedly connected to the side of the U-shaped post 10, a locking groove 12 on the side of the column 11, the inner wall of the locking groove 12 attached to the surface of the locking plate 7, and grooves 13 on both the front and rear sides of the threaded ring 9.

[0030] It should be noted that when the user rotates the threaded ring 9, the threaded cylinder 3 and the threaded ring 9 cooperate to move the threaded ring 9 up or down and align or offset the groove 13 on the threaded ring 9 with the U-shaped post 10. When the distance between the threaded ring 9 and the upper cover 4 is the smallest, the groove 13 is offset from the U-shaped post 10. When the distance between the threaded ring 9 and the upper cover 4 is the largest, the groove 13 is aligned with the U-shaped post 10.

[0031] When the groove 13 is misaligned with the U-shaped post 10, the threaded ring 9 makes the locking groove 12 and the locking plate 7 in close contact. Through the cooperation of the locking groove 12 and the locking plate 7, the first cylinder 2 cannot move on the sleeve body 1. When the groove 13 is aligned with the U-shaped post 10, the locking groove 12 and the locking plate 7 can be separated by pushing the U-shaped post 10 into the groove 13, and the first cylinder 2 can slide up and down on the sleeve body 1. At the same time, since the column 11 is provided with multiple locking grooves 12, the distance between the top cover 4 and the sleeve body 1 can be changed by inserting the locking plate 7 into the locking grooves 12 at different positions.

[0032] Both the upper and lower ends of the sleeve body 1 are open. The bottom of the inner wall of the sleeve body 1 is provided with a sliding edge. Under the guidance of the sliding edge, the nut or bolt can smoothly fit into the inner wall of the sleeve body 1, which makes it easier for the user to tighten the bolt or nut.

[0033] like Figures 1 to 7 As shown, a limiting block 14 is fixedly connected to the surface of the sleeve body 1, and a limiting groove 15 is opened on the surface of the first cylinder 2. The inner wall of the limiting groove 15 is in contact with the surface of the limiting block 14.

[0034] It should be noted that the cooperation between the limiting block 14 and the limiting groove 15 reduces the horizontal torque on the locking plate 7 and the column 11 when the user rotates the bolt or nut using the guide sleeve.

[0035] like Figures 1 to 11As shown, a second cylinder 16 is fixedly connected to the surface of the first cylinder 2. An elastic rubber cylinder 17 is attached to the surface of the second cylinder 16. A retaining ring 18 is attached to both the upper and lower sides of the elastic rubber cylinder 17. The inner wall of the retaining ring 18 is fixedly connected to the surface of the second cylinder 16. A round hole 19 is opened on both the left and right sides of the second cylinder 16. An arc groove 20 is opened on the side of the limiting block 14. Steel balls 21 are attached to the inner wall of the arc groove 20, the inner wall of the round hole 19, and the inner wall of the elastic rubber cylinder 17.

[0036] Among them, the elasticity of the elastic rubber cylinder 17 is greater than the weight of the steel ball 21, and the thickness of the second cylinder 16 is less than the diameter of the steel ball 21.

[0037] It should be noted that the number and spacing of the arc-shaped grooves 20 and the locking grooves 12 are equal. When the user adjusts the distance between the sleeve body 1 and the upper cover 4, the locking groove 12 can pause when it is aligned with the locking plate 7 through the cooperation of the second cylinder 16, the elastic rubber cylinder 17, the retaining ring 18, the round hole 19, the arc-shaped grooves 20 and the steel ball 21, so that the user can quickly align the locking groove 12 with the locking plate 7.

[0038] like Figures 1 to 6 As shown, an annular groove 22 is provided on the surface of the sleeve body 1, and an anti-slip rubber ring 23 is fitted to the inner wall of the annular groove 22.

[0039] The anti-slip rubber ring 23 is located below the first cylinder 2, and the thickness of the anti-slip rubber ring 23 is greater than the depth of the annular groove 22.

[0040] It should be noted that when the user adjusts the distance between the sleeve body 1 and the upper cover 4, pinching the anti-slip rubber ring 23 can prevent the fingers from slipping on the sleeve body 1.

[0041] When adjusting the length of the guide sleeve, the user first rotates the threaded ring 9 to maximize the distance between the threaded ring 9 and the upper cover 4, and aligns the groove 13 with the U-shaped post 10. At this time, by pushing the U-shaped post 10 into the groove 13, the locking plate 7 can be separated from the locking groove 12. Then, by moving the sleeve body 1, the distance between the sleeve body 1 and the upper cover 4 can be adjusted.

[0042] When the distance between the sleeve body 1 and the upper cover 4 reaches a suitable value, and the locking groove 12 is aligned with the locking plate 7, the U-shaped post 10 is moved out of the groove 13 by rotating the threaded ring 9 under the action of the inclined side of the groove 13. Through the cooperation of the threaded ring 9 and the U-shaped post 10, the locking plate 7 contacts the locking groove 12. When the distance between the threaded ring 9 and the upper cover 4 is the smallest, the rotation of the threaded ring 9 is stopped. At this time, the groove 13 on the threaded ring 9 is misaligned with the U-shaped post 10. Through the cooperation of the threaded ring 9 and the U-shaped post 10, the locking groove 12 and the locking plate 7 are tightly fitted. Then, through the cooperation of the locking groove 12 and the locking plate 7, the distance between the sleeve body 1 and the upper cover 4 cannot be changed.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
