Description

Technical Field

[0001] This utility model is an adjustable quick-release sleeve for a portable printer, belonging to the field of quick-release sleeves. Background Technology

[0002] Portable printers, also known as miniature printers, are small and easy to carry. They are mainly designed to meet the printing needs of users while on the go and are widely used in various office fields such as traffic police enforcement. There are many types of printers. According to whether the printing element strikes the paper, they are divided into impact printers and non-impact printers. According to the structure of the printed characters, they are divided into full-character printers and dot matrix character printers. According to how a line of text is formed on the paper, they are divided into serial printers and line printers.

[0003] Chinese patent discloses a portable printer pull-button type quick-release belt buckle device (publication number: CN207772613U), including a quick-release body and a back buckle. The quick-release body has a buckle, a belt fixing hole, and a torsion spring; the back buckle has a snap-on button and a printer fixing screw hole. In use, the back buckle, which is fixed to the printer, is inserted into the quick-release body. The buckle retracts under force, the back buckle slides in, and after the snap-on button is in place, the buckle resets and locks under the action of the torsion spring, preventing the back buckle from coming out.

[0004] Conventional quick-release sleeves typically only restrict the carrying of one type of portable printer. Their fixed size makes them inconvenient for users to carry, and adjustments and replacements are cumbersome and inconvenient, reducing the user experience. In addition, the fasteners are usually a set structure, making it difficult to replace them in different situations. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustable quick-release sleeve for portable printers. This solves the problem that conventional quick-release sleeves can only restrict the carrying of portable printers of one size, making them difficult for users to carry due to their fixed size. Adjusting and replacing them is also cumbersome and inconvenient, reducing the user experience. In addition, the fasteners are usually a matching structure, making it difficult to replace them in different situations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable portable printer quick-release sleeve, comprising a clip, a support frame, and a fixing bolt. The inner rear end of the clip is connected to the support frame, and the inner side of the support frame is provided with a fixing bolt. The support frame comprises a main body, a limiting block, a first magnetic strip, an adjusting frame, a screw hole, and a second magnetic strip. The top of the main body is connected to the limiting block, and the left side of the top of the limiting block is fixed to the first magnetic strip. The top of the main body is movably fitted with the adjusting frame. A screw hole is provided on the left side of the top of the adjusting frame, and the right end of the top of the adjusting frame is fixed to the second magnetic strip. The outer side of the limiting block is connected to the clip, and the inner side of the screw hole is threadedly connected to the fixing bolt.

[0007] Furthermore, the adjustment frame is hook-shaped, and the bent surface of the adjustment frame faces the position of the first magnetic strip.

[0008] Furthermore, the screw holes are equidistantly located at the top left end of the adjustment frame, and screw holes are also located at the top right end of the main body, with the screw holes on the main body being spaced at the same distance as the screw holes on the adjustment frame.

[0009] Furthermore, there are two magnetic strips in total, with the first magnetic strip attached and fixed to the top left end of the main body, and the second magnetic strips respectively located at the inner hooks of the left and right end adjustment frames.

[0010] Furthermore, a bolt is provided at the center of the top of the limiting block, and the bolt is connected to the main body through the limiting block.

[0011] Advantages: This utility model provides an adjustable portable printer quick-release sleeve. By setting a support frame at the rear end of the card, and separating the main body and adjustment frame inside the support frame, it is easy for users to adjust. Furthermore, the setting of fixing bolts can achieve adjustment for portable printers of different sizes. Not only is the adjustment method convenient, but the limit block can also be adjusted according to different situations, thereby improving the user experience. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1 This utility model provides an adjustable portable printer quick-release sleeve through improvement, including a clip 1, a support frame 2 and a fixing bolt 3. The inner rear end of the clip 1 is connected to the support frame 2, and the inner side of the support frame 2 is provided with the fixing bolt 3, which facilitates the limiting and fixing effect with the support frame 2.

[0019] Please see Figure 2 and Figure 3 This utility model provides an adjustable quick-release sleeve for a portable printer through improvements. The support frame 2 includes a main body 21, a limiting block 22, a first magnetic strip 23, an adjusting frame 24, a screw hole 25, and a second magnetic strip 26. The top of the main body 21 is connected to the limiting block 22. A bolt 221 is provided at the middle of the top of the limiting block 22, and the bolt 221 is connected to the main body 21 through the limiting block 22. The left side of the top of the limiting block 22 is fixed to the first magnetic strip 23. There are two first magnetic strips 23 and two second magnetic strips 26. The first magnetic strips 23 are attached and fixed to the top left end of the main body 21, and the second magnetic strips 26 are respectively provided at the left and right ends of the adjusting frame. At the hook on the inner side of the frame 24, the top of the main body 21 is movably fitted with the adjusting frame 24. The adjusting frame 24 is hook-shaped, and the bent side of the adjusting frame 24 faces the position of the first magnetic strip 23. A screw hole 25 is opened on the left side of the top of the adjusting frame 24. The screw holes 25 are equally spaced on the left side of the top of the adjusting frame 24. A screw hole 25 is also opened on the right side of the top of the main body 21. The distance between the screw holes 25 on the main body 21 and the distance between the screw holes 25 on the adjusting frame 24 are the same. The right side of the top of the adjusting frame 24 is fixed to the second magnetic strip 26 as a whole. The outer side of the limiting block 22 is connected to the clip 1. The inner side of the screw hole 25 is connected to the fixing bolt 3 by thread. The setting of the two magnetic strips improves the connection stability.

[0020] The work process is as follows:

[0021] 1. When the portable printer needs to be carried, the user can adjust the position of the screw hole 25 on the adjustment frame 24 and the screw hole 25 on the main body 21 according to the size of the portable printer. This adjusts the length of the adjustment frame 24, thereby achieving the effect of adjusting the printer of different sizes. Finally, the fixing bolt 3 is fixed through the screw hole 25 by using an external screwdriver to fix the main body 21 and the adjustment frame 24.

[0022] Second, place the printer on the hook of the adjustment frame 24. The hook of the adjustment frame 24 can limit and lock the printer. The first magnetic strip 23 and the second magnetic strip 26 can further limit and fix the printer. After fixing, slide the clip 1 down from the top of the limiting block 22 to achieve the effect of locking and fastening, which makes it easy to carry the printer. If the limiting block 22 needs to be replaced, simply turn the bolt 221 to replace the limiting block 22.
