DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] Specific implementation method 1: Combination Figure 1-7 As shown, a trigger light box comprises: a box body 1, a light guide plate 101 is arranged inside the box body 1, swing arms 102 connected with rotating shafts are symmetrically arranged on both sides of the box body 1 above the light guide plate 101, and an elastic member 103 in contact with the box body 1 is arranged at one end of the swing arm 102, and a conductive plate 104 and a docking plate 105 are respectively arranged in the middle of the box body 1; a reel assembly 2, both ends of the reel assembly 2 are respectively connected to the swing arm 102, and a trigger column 3 is connected to the docking plate 105 in the middle through a pull rope, and the trigger column 3 is in contact with the docking plate 105; wherein the conductive plate 104 and the docking plate 105 are respectively connected to the control circuit, and are energized and turned on after docking, so as to turn on the light group;

[0027] In the non-working state, the conductive plate 104 and the docking plate 105 are in a non-contact state, and the light group inside the box 1 is in an off state. When in use, the X-ray photo is inserted into the upper position of the box 1, squeezed between the reel assembly 2 and the light guide plate 101, overcoming the elastic force of the elastic member 103 itself, and in pushing the photo to move, the pull rope is wound through the reel assembly 2, thereby pulling the trigger column 3 to cause the docking plate 105 to deform. When the photo is inserted into place, the docking plate 105 also comes into contact with the conductive plate 104 to achieve power-on and turn on the internal light group. No additional operation is required, and it is easy to use. When use is completed, the photo is pulled out, driving the reel assembly 2 to rotate in the opposite direction, and cooperating with the elastic force of the docking plate 105 itself to achieve reset separation, effectively solving the problem of constant light use and reducing energy consumption.

[0028] A preferred embodiment, in combination with Figure 5 As shown, a slot 106 connected to the elastic member 103 is provided at the upper end of the swing arm 102 to facilitate replacement of the elastic member 103 and later maintenance. The elastic member 103 can be made of spring steel.

At the same time, both ends of the main shaft 201 are connected to the swing arms 102 on both sides as rotating shafts. The driving wheel 202 is in contact with the upper surface of the light guide plate 101 under normal conditions. When inserting a photo, the friction force generated by the contact between the driving wheel 202 and the surface of the photo completes the drive rotation of the main shaft 201 during the displacement of the photo. The structure is ingenious and the layout is reasonable.

[0030] A preferred embodiment, in combination with Figure 6 and Figure 7 As shown, positioning strips 203 are provided on both sides of the main shaft 201, and a notch connected to the positioning strip 203 is provided in the middle of the driving wheel 202. The driving wheel 202 is connected to the positioning strip 203 through the notch, which facilitates the installation of the driving wheel 202 and the adjustment of the position.

[0031] A preferred embodiment, in combination with Figure 6 As shown, in order to increase the friction force generated by contact with the photo, a contact layer 204 is provided on the outer circle of the driving wheel 202. The contact layer 204 is made of rubber material, which can effectively increase the friction force after contact, thereby facilitating the rotation of the main shaft 201.

[0032] In a preferred embodiment, a plurality of anti-slip grooves 205 are provided along the circumferential direction of the contact layer 204 to further prevent slipping.

[0033] A preferred embodiment, in combination with Figure 4 and Figure 7 As shown, a guide assembly 4 connected to the trigger column 3 is provided at the rear of the box body 1, which is used to keep the trigger column 3 in linear displacement to prevent the trigger column 3 from loosening;

[0034] Specifically: the guide assembly 4 includes a sleeve 401 and a slide column 402; the sleeve 401 is symmetrically arranged and fixedly connected to the rear of the box body 1, such as by bonding; two slide columns 402 are also used, one end of the slide column 402 is inserted into the sleeve 401 to form a sliding connection, and the other end is connected to the trigger column 3. During the process of winding the pull rope, the slide column 402 is driven to move along the sleeve 401 to ensure the displacement stability of the trigger column 3.

[0035] A preferred embodiment, in combination with Figure 4 and Figure 7 As shown, a transverse plate 403 is provided on the slide column 402 , and a tension spring 404 connected to the box body 1 is provided in the middle of the transverse plate 403 , so as to facilitate the reset with the docking plate 105 . Specific implementation method 2

[0037] Combination Figure 2 As shown, the insertion requirements of multiple X-rays can be met by increasing the width of the box 1, lengthening the main shaft 201, and increasing the number of driving wheels 202. Specific implementation method three

[0039] Combination Figure 3 As shown, a positioning pin is provided inside the box body 1 near the light guide plate 101 , and the positioning pin contacts the surface of the elastic member 103 , and plays a role of blocking the elastic member 103 when the swing arm 102 rotates counterclockwise.
