Traditional solutions mostly use integral welded devices, which are not convenient for the installation and fixing of laser printers of different sizes. They have poor applicability and require manual adjustment and fixing during support and fixing, which is time-consuming and labor-intensive to use.

However, it requires manual input of the printer size before locking. For equipment whose size is unknown, manual measurement is required, which is time-consuming and labor-intensive. In addition, the printer is only fixed by the fixing devices around it. When the printer is subjected to a large horizontal external force, it is easy to cause damage to the fixing structure.

[0023] like Figures 1 to 4 As shown, a laser printer fixing device includes a box body 1, a self-locking structure 2 and a longitudinal pressure plate 3. The box body 1 is a hollow box body.

A longitudinal spring 8 is provided at the bottom of the longitudinal pressure plate 3. A fixed plate 5 is provided at the bottom of the longitudinal spring 8. A longitudinal cylinder 7 is provided at the bottom of the fixed plate 5. The telescopic end of the longitudinal cylinder 7 penetrates the fixed plate 5 and is connected to the longitudinal pressure plate 3. The telescopic end of the longitudinal cylinder 7 is located inside the longitudinal spring 8. A transverse cylinder 6 is also provided at the bottom of the fixed plate 5. The telescopic end of the transverse cylinder 6 is connected to the self-locking structure 2. Sensing plates 31 are provided on both sides of the longitudinal pressure plate 3. A sensor 22 is provided on one side of the self-locking structure 2. The sensor 22 is preferably an optical sensor, and the sensor 22 is used to sense the sensing plate 31.
[0024] The box body 1 is a rectangular box body, and a support plate 9 is provided in the box body 1. The support plate 9 is parallel to the bottom plane of the box body 1. The self-locking structure 2 is located on the support plate 9. The number of the self-locking structures 2 is four groups, and the four groups of self-locking structures 2 are evenly distributed around the longitudinal pressure plate 3 in a circular array. Any group of self-locking structures 2 includes a connecting frame 21, a pressure sensor 25, a transverse spring 26 and a transverse pressure plate 27. The connecting frame 21 is an inverted F-shaped frame, the pressure sensor 25 is located on one side of the longitudinal beam of the F-shaped connecting frame, and the transverse spring 26 is located on the other side of the longitudinal beam of the F-shaped connecting frame. The elastic end of the transverse spring 26 is connected and fixed to the transverse pressure plate 27, and the transverse beam at the end of the F-shaped connecting frame is connected to the telescopic end of a transverse cylinder 6. The telescopic movement of the transverse cylinder 6 drives the transverse pressure plate 27 to move synchronously. A buffer layer 28 is provided on one side of the transverse pressure plate 27, and the buffer layer 28 is made of rubber.
[0025] Four fixing tubes 11 are embedded on the side wall of the box body 1, and the four fixing tubes 11 correspond to four groups of self-locking structures 2. Any one of the fixing tubes 11 is an inverted L-shaped hollow tube, and an elastic strip 12 is inserted into any one of the fixing tubes 11. The elastic strip 12 is made of highly elastic material, preferably silicone material. One end of the elastic strip 12 is connected to the self-locking structure 2, and a limiting block 13 is provided at the other end of the elastic strip 12. The limiting block 13 is engaged with the opening position of the fixing tube 11 to further limit the telescopic distance of the elastic strip 12 along the direction of the fixing tube 11. The elastic strip 12 is bent and stretched along the fixing tube 11 to connect and fix the self-locking structure 2, so that the self-locking structure 2 will not tilt or flip relative to the side wall of the box body where the fixing tube 11 is located.
[0026] Eight slide rails 23 are fixed on the inner wall of the top of the box body 1, and every two slide rails 23 are paired with a group of self-locking structures 2. Slide blocks 24 that fit with the slide rails 23 are provided on the outer walls on both sides of any group of self-locking structures 2. The sliders 24 and the slide rails 23 limit the sliding of the self-locking structure 2 in the horizontal direction.
[0027] A control compartment 4 is provided on the inner wall of the bottom of the box body 1. The control compartment 4, the sensor 22, the self-locking structure 2, the transverse cylinder 6 and the longitudinal cylinder 7 are electrically connected to each other. A button 41 is provided on the side of the control compartment 4. The button 41 controls the longitudinal cylinder 7 to lift, thereby driving the longitudinal pressure plate to move to the initial position.
[0028] The implementation principle of Example 1 of the present application is as follows: when fixing the printer, the printer to be fixed is placed above the longitudinal pressure plate 3. Under the longitudinal pressure applied by the printer, the longitudinal spring 8 is elastically compressed, so that the sensing plate 31 on the side of the longitudinal pressure plate 3 moves to a position facing the sensor 22. The sensor 22 controls the transverse cylinder 6 to extend and retract, driving the transverse pressure plate 27 of the self-locking structure 2 to squeeze the side wall of the printer. The pressure sensor 25 in the self-locking structure 2 senses the pressure of the transverse pressure plate, thereby controlling the extension and retraction length of the transverse cylinder 6 to just be able to press and fix the printer. When the printer needs to be released, the button 41 is used to control the extension and retraction end of the longitudinal cylinder 7 to lift, thereby lifting the longitudinal pressure plate 3 to the initial position. When the sensor 22 senses the movement of the sensing plate 31, it controls the extension and retraction end of the transverse cylinder 6 to move the transverse pressure plate to the initial position and thus release the pressure on the printer.
[0029] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above and that the present application can be implemented in other specific forms without departing from the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
