[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] like Figures 1 to 3 As shown, the embodiment of the utility model discloses a light-transmitting sheet fixing device for a packaging box, which is arranged on a box body.

[0022] A storage cavity is provided in the box body 1, a light-transmitting opening communicating with the storage cavity is provided on the front of the box body 1, and a light-transmitting sheet 3 is provided in the storage cavity at the light-transmitting opening;

[0023] The mounting mechanism comprises an outer frame 2, a fixing rod 201, an end cover 202 and an inner frame 4. The fixing rod 201 is fixedly arranged on the outer frame 2. The end cover 202 is fixedly arranged on the end of the fixing rod 201 away from the outer frame 2. The diameter of the fixing rod 201 is smaller than the diameter of the end cover 202. The outer end of the end cover 202 is in a truncated cone shape, and the diameter of the end of the end cover 202 away from the fixing rod 201 is smaller than the diameter of the end of the end cover 202 close to the fixing rod 201. The end cover 202 is provided with a card slot 203 extending to the fixing rod 201, and the fixing rod 201 can generate elastic deformation at the card slot 203. The box body 1 is provided with a through hole 1 on the side of the light-transmitting port to be matched with the end cover 202. The light-transmitting sheet 3 is provided with a through hole 2 301 to be matched with the end cover 202. The inner frame 4 is located in the storage cavity and is provided with a through hole 3 401 to be matched with the fixing rod 201.

[0024] In at least one embodiment, the fixing rods 201 are arranged in multiple groups and fixedly arranged at intervals around the outer frame 2. The outer frame 2 is limited at multiple points by multiple groups of fixing rods 201 to enhance the connection stability between the outer frame 2 and the light-transmitting sheet 3 and the inner frame 4.

[0025] In at least one embodiment, a retaining ring 204 matched with the inner wall of the light-transmitting opening is fixedly provided on the outer frame 2. The retaining ring 204 is provided to shield the inner wall of the light-transmitting opening, thereby improving the viewing experience of consumers.

[0026] In at least one embodiment, a gasket 205 is fixedly provided on one side of the outer frame 2 close to the fixing rod 201, and the gasket 205 is provided with a through hole 4 matched with the fixing rod 201. The gasket 205 is provided to improve the sealing performance of the abutment between the outer frame 2 and the box body 1.

[0027] In at least one embodiment, the fixing rod 201 and the end cover 202 are both made of polyethylene, so that the fixing rod 201 has good resilience.

[0028] In at least one embodiment, the outer edge of the light-transmitting sheet 3 is aligned with the outer edge of the inner frame 4 , so that the inner frame 4 and the light-transmitting sheet 3 are completely in contact with each other to ensure sealing.

[0029] When the product is placed in the box body 1, the fixing rods 201 and the end covers 202 on both sides of the outer frame 2 are inserted into the storage cavity through the through hole 1 on the side of the light-transmitting opening of the box body 1, and the outer frame 2 is abutted against the box body 1. The light-transmitting sheet 3 is located in the storage cavity and covers the light-transmitting opening. The fixing rods 201 and the end covers 202 are passed through the through hole 2 301 on the light-transmitting sheet 3, and then the inner frame 4 is covered on the light-transmitting sheet 3 and the fixing rods 201 are passed through the through hole 3 401. In the process of inserting the truncated cone part of the outer end of the end cover 202 into the through hole 3 401, the fixing rods 201 are squeezed and pressed at the slot 203. Deformation occurs, so that the outer walls of the end covers 202 on both sides of the slot 203 abut against the inner walls of the through hole three 401 and then approach each other and are inserted into the through hole three 401. After the end covers 202 pass through the through hole three 401, the fixing rod 201 is disengaged from the extrusion at the slot 203 and drives the end covers 202 to return to their original state, so that the end covers 202 limit the inner frame 4. Consumers can directly observe the product through the light-transmitting sheet 3. The device combines and fixes the light-transmitting sheet 3 and the box body 1 through the outer frame 2 and the inner frame 4. The operation is convenient and the sealing is good, which avoids the hidden danger of food contamination by adhesion and improves safety.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application 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 cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
