[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Combine the following Figure 1-Figure 6 The utility model is described as a scanner button installation structure, which includes a scanner handle 100, a button 200 and a rebound component 300.

[0035] The scanner handle 100 has a cavity 101 inside, and a through slot 102 communicating with the cavity 101 is formed on the side wall of the scanner handle 100;

[0036] The button 200 is disposed in the cavity 101, one end of the button 200 is rotatably connected to the side wall of the cavity 101, and a part of the button 200 can movably pass through the through slot 102;

[0037] One end of the rebound component 300 is connected to the side wall of the cavity 101 , and the other end is connected to the key 200 . The rebound component 300 is used to provide resistance when the key 200 is pressed and rotated.

[0038] That is to say, when the button 200 is not subjected to external force, the button 200 rests against the side wall of the cavity 101 through the rebound component 300, and a part of the button 200 passes through the through slot 102 and extends out of the scanner handle 100 for the user to press. The button 200 has a structure that limits the button 200 from completely passing through the through slot 102. The main structure of the button 200 is roughly the same as the existing button structure. When the user holds the handle and presses the button 200, the button 200 rotates around the rotation fulcrum toward the inside of the handle to trigger scanning. The rebound component 300 gives the button 200 a reaction force when it rotates inward to increase the pressing force and improve the user experience. The rebound component 300 is also used to rebound the button 200 to its initial position after the user releases the button 200.

[0039] In terms of specific structure, the key 200 includes a key body 201, and a rotating shaft 202 is disposed on both sides of one end of the key body 201. A rotating groove 103 corresponding to the rotating shaft 202 is disposed on the side wall of the cavity 101, and the rotating shaft 202 is rotatably connected in the rotating groove 103. In terms of specific position, the rotating shaft 202 is respectively located on two opposite sides of the key body 201 near the upper end, and the rotating groove 103 is also respectively disposed on two opposite sides of the upper end of the cavity 101.

[0040] The rebound assembly 300 includes a torsion spring, which is movably mounted on the rotating shaft 202, and two elastic arms of the torsion spring respectively abut against the key body 201 and the side wall of the cavity 101. Two torsion springs are provided, one torsion spring is provided on a rotating shaft 202, so as to achieve balanced force on the left and right sides of the key 200.

[0041] The torsion spring is a torsion spring, and the torsion spring includes a torsion spring body 301, and the two ends of the torsion spring body 301 respectively have a first elastic arm 302 and a second elastic arm 303. The torsion spring body 301 is sleeved on the rotating shaft 202, and the free end of the first elastic arm 302 is clamped on the key body 201, and the free end of the second elastic arm 303 is clamped on the side wall of the cavity 101. In other words, the end of the rotating shaft 202 is located in the rotating groove 103, and there is a certain gap between the outer side wall of the key body 201 and the corresponding side wall of the cavity 101. The torsion spring body 301 is sleeved on a part of the rotating shaft 202 located in the gap. It can be understood that the gap can provide enough working space for the torsion spring.

[0042] The button body 201 is provided with a first clamping groove 203 for the first elastic arm 302 to clamp, and the side wall of the cavity 101 is provided with a second clamping groove 104 for the second elastic arm 303 to clamp.

[0043] The free end of the first elastic arm 302 is bent toward the first slot 203 to form a first engaging portion 304 . The first engaging portion 304 is engaged in the first slot 203 .

[0044] The free end of the second elastic arm 303 is bent toward the second clamping slot 104 to form a second clamping portion 305 . The second clamping portion 305 is clamped in the second clamping slot 104 .

[0045] In terms of specific position, the rotating groove 103 and the second clamping groove 104 are both located on the upper end surface of the side wall of the cavity 101, so that when installing the button 200, the rotating shaft 202 can be placed in the rotating groove 103 and the second clamping portion 305 can be clamped into the second clamping groove 104. After installation, a pressing piece (not shown) will be installed on the top of the cavity 101 to press the rotating shaft 202 and the second clamping portion 305 together so that the button 200 can work normally.

[0046] The length of the first elastic arm 302 is greater than that of the second elastic arm 303, and the first elastic arm 302 is closer to the key body 201 than the second elastic arm 303. At the beginning of the design, the lengths of the first elastic arm 302 and the second elastic arm 303 can be determined according to the required pressing force, and then the position of the second slot 104 on the side wall of the cavity 101 and the position of the first slot 203 on the key body 201 can be determined; or, the pressing force can be changed by selecting different wire diameters of the torsion spring (i.e., the thickness of the wire constituting the torsion spring), wherein the larger the wire diameter, the greater the pressing force, and the smaller the wire diameter, the smaller the pressing force. Of course, the factors affecting the magnitude of the reaction torque generated by the torsion spring are determined by many aspects, and can be designed according to the actual required pressing force.

[0047] In previous designs, such as Figure 7As shown, the pressing force of the key body 201 is mainly provided by a plastic elastic part 204, and the plastic elastic part 204 is often integrally formed with the key body 201. After long-term use, the pressing force becomes weaker. When the pressing force needs to be improved, the entire key body 201 together with the plastic elastic part 204 needs to be replaced.

[0048] In the present application, the pressing force of the key body 201 is provided by a torsion spring, and the corresponding torsion spring can be selected according to the actual required pressing force. The torsion spring can provide a stronger pressing force than the plastic elastic part 204, and has a longer service life. When the pressing force of the key body 201 needs to be changed, only the torsion spring needs to be replaced.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
