The size of the dustproof cloth can be selected and equipped according to the size of the cash register display screen.

[0004] Currently, cash registers on the market require protective devices to protect their displays during use. However, existing protective devices can only protect the display screen and cannot buffer the forces that are applied to it. This means that when the display screen is hit by an external object, it will still shake or even be damaged due to the impact force, thus affecting the effectiveness of the protective device. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for a cash register display screen, so as to solve the problem mentioned in the background art of the difficulty in buffering the forces exerted on the cash register display screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a cash register display screen, comprising a protective frame body, a buffer assembly, and a connecting assembly; the protective frame body comprises two bodies, each containing a buffer assembly, and the two protective frame bodies form a protective cavity for the cash register display screen; the two protective frame bodies are interconnected via the connecting assembly; the buffer assembly comprises a contact plate and buffer blocks; the contact plate is slidably disposed within the protective frame body, and its inner side contacts the side of the cash register display screen; a plurality of buffer blocks are uniformly fixed to the outer side of the contact plate, and the ends of the buffer blocks are fixedly connected to the inner wall of the protective frame body.

[0007] Preferably, both the protective frame body and the contact plate are U-shaped structures, and the cross-section of the protective frame body is U-shaped.

[0008] Preferably, the buffer block has an arc-shaped structure, and the sum of the thickness of the buffer block and the thickness of the contact plate is less than the height of the inner wall of the protective frame.

[0009] Preferably, the connecting assembly includes a fixed plate, a fixed seat, a movable groove, a receiving groove, a moving rod, a sliding block, and a connecting block; two fixed plates are symmetrically fixed on both sides of one of the protective frame bodies; two fixed seats are symmetrically fixed on both sides of the other protective frame body; a movable groove is formed on the side of the fixed seat near the fixed plate; a receiving groove is formed in the movable groove; the moving rod slides through the receiving groove; the sliding block slides in the receiving groove and is fixedly connected to the end of the moving rod, and there is a gap between the sliding block and the inner side wall and the inner bottom wall of the receiving groove; at least one connecting block is fixed on the side of the fixed plate near the fixed seat, and the end of the connecting block passes through the receiving groove and contacts the bottom surface of the sliding block.

[0010] Preferably, the connecting block has an L-shaped structure with a smaller top and a larger bottom, and the thickness of the vertical plate of the connecting block is adapted to the distance between the sliding block and the inner sidewall of the receiving groove, and the thickness of the horizontal plate of the connecting block is adapted to the distance between the sliding block and the bottom wall of the receiving groove.

[0011] Preferably, the length of the horizontal plate of the connecting block and the distance between the moving rod and the inner sidewall of the receiving groove are adapted to each other.

[0012] Preferably, the connecting assembly further includes a slot, a fixed rod, and a spring; the sliding block has a slot on the side away from the moving rod; the fixed rod slides through the slot and is fixedly connected to the inner wall of the receiving slot; the two ends of the spring are fixedly connected to the inner wall of the slot and the fixed rod, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a buffer assembly, places two protective frame bodies on both sides of the cash register display screen, so that the contact plate contacts the side of the cash register display screen. The position between the two protective frame bodies is fixed by a connecting assembly. By setting a buffer block, when the protective frame body is hit by an external object, the protective frame body will move, causing the buffer block to deform under force and automatically adapt to tilting. The force generated by the deformation of the buffer block can cancel out the impact force, thereby buffering the cash register display screen. Since the buffer block has an arc-shaped structure, it can not only ensure the stability of the position of the protective frame body and the contact plate, but also automatically adapt to the direction of force and tilt. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. It can not only protect the cash register display screen, but also buffer the impact force on the cash register display screen, thereby extending the service life of the cash register display screen.

[0015] 2. This utility model, by setting a connecting component, allows the moving rod to move when pressed, causing the sliding block to slide within the receiving groove and the fixed rod to slide within the empty groove. This causes the spring to contract under force until it reaches its maximum contraction. At this point, there is no overlap between the sliding block and the movable groove. Subsequently, the connecting block is inserted into the movable groove and the receiving groove. Because the length of the horizontal plate of the connecting block and the distance between the moving rod and the inner wall of the receiving groove are matched, the horizontal plate of the connecting block and the moving rod do not contact each other until the fixed plate and the fixed seat contact each other. At this point, the moving rod is released, and under the elastic force of the spring, the fixed rod slides in the opposite direction within the empty groove, causing the sliding block to slide in the opposite direction within the receiving groove. This causes the moving rod to move in the opposite direction until the side of the sliding block contacts the inner wall of the receiving groove. At this point, the side of the sliding block contacts the vertical plate of the connecting block, and the bottom surface of the sliding block contacts the horizontal plate of the connecting block, thus fixing the position between the two protective frame bodies. This not only facilitates the replacement of the protective frame bodies but also improves the stability between the protective frame bodies and the cash register display screen.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a protective device for a cash register display screen, comprising a protective frame body 1, a buffer assembly 2, and a connecting assembly 3; there are two protective frame bodies 1, each containing a buffer assembly 2, and the two protective frame bodies 1 form a protective cavity for the cash register display screen, which is connected to each other via the connecting assembly 3; the buffer assembly 2 includes a contact plate 201 and a buffer block 202; the contact plate 201 is slidably disposed within the protective frame body 1, and its inner side contacts the side of the cash register display screen; several buffer blocks 202 are uniformly and fixedly connected to the outer side of the contact plate 201, and the ends of the buffer blocks 202 are fixedly connected to the inner wall of the protective frame body 1; both the protective frame body 1 and the contact plate 201 are U-shaped structures, and the cross-section of the protective frame body 1 is U-shaped; the buffer blocks 202 are arc-shaped structures, and the sum of the thickness of the buffer blocks 202 and the thickness of the contact plate 201 is less than the height of the inner wall of the protective frame body 1, so as to facilitate the side of the cash register display screen being within the protective frame body 1.

[0025] This invention, by setting a buffer component 2, places two protective frame bodies 1 on both sides of the cash register display screen, so that the contact plate 201 contacts the side of the cash register display screen. The position between the two protective frame bodies 1 is fixed by the connecting component 3. By setting a buffer block 202, when the protective frame body 1 is hit by an external object, the protective frame body 1 will move, causing the buffer block 202 to deform under force and automatically adapt to tilting. The force generated by the deformation of the buffer block 202 can cancel out the impact force, thereby buffering the cash register display screen. Since the buffer block 202 has an arc-shaped structure, it can not only ensure the stability of the position of the protective frame body 1 and the contact plate 201, but also automatically adapt to the direction of force and tilt. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. It can not only protect the cash register display screen, but also buffer the impact force on the cash register display screen, thereby extending the service life of the cash register display screen.

[0026] In a preferred embodiment, the connecting assembly 3 includes a fixed plate 301, a fixed seat 302, a movable groove 303, a receiving groove 304, a moving rod 305, a sliding block 306, a connecting block 307, a hollow groove 308, a fixed rod 309, and a spring 310; two fixed plates 301 are symmetrically fixedly connected to both sides of one of the protective frame bodies 1; two fixed seats 302 are symmetrically fixedly connected to both sides of the other protective frame body 1; a movable groove 303 is provided on the side of the fixed seat 302 near the fixed plate 301; a receiving groove 304 is provided in the movable groove 303; the moving rod 305 slides through the receiving groove 304; the sliding block 306 slides in the receiving groove 304 and is fixedly connected to the end of the moving rod 305, and there is a gap between the sliding block 306 and the inner side wall and the inner bottom wall of the receiving groove 304; the connecting block 307 is fixedly connected to the side of the fixed plate 301 near the fixed seat 302, and... The end of the connecting block 307 passes through the receiving groove 304 and contacts the bottom surface of the sliding block 306. The connecting block 307 has an L-shaped structure that is smaller at the top and larger at the bottom. The thickness of the vertical plate of the connecting block 307 is matched with the distance between the sliding block 306 and the inner wall of the receiving groove 304. The thickness of the horizontal plate of the connecting block 307 is matched with the distance between the sliding block 306 and the inner bottom wall of the receiving groove 304. The length of the horizontal plate of the connecting block 307 is matched with the distance between the moving rod 305 and the inner wall of the receiving groove 304. A slot 308 is provided on the side of the sliding block 306 away from the moving rod 305. The fixing rod 309 slides through the slot 308 and is fixedly connected to the inner wall of the receiving groove 304. The two ends of the spring 310 are fixedly connected to the inner wall of the slot 308 and the fixing rod 309, respectively. When the spring 310 is contracted to its maximum extent, the side of the sliding block 306 does not contact the inner wall of the receiving groove 304.

[0027] This utility model, by setting a connecting component 3, presses the moving rod 305, causing the moving rod 305 to move, causing the sliding block 306 to slide within the receiving groove 304, and the fixed rod 309 to slide within the empty groove 308, causing the spring 310 to contract under force until the spring 310 contracts to its maximum limit. At this point, there is no overlap between the sliding block 306 and the movable groove 303. Subsequently, the connecting block 307 is inserted into the movable groove 303 and the receiving groove 304. Because the length of the horizontal plate of the connecting block 307 and the distance between the moving rod 305 and the inner sidewall of the receiving groove 304 are matched, the horizontal plate of the connecting block 307 does not contact the moving rod 305 until the fixed plate 309... When the 01 and the fixed base 302 are in contact with each other, the moving rod 305 is released. Under the elastic force of the spring 310, the fixed rod 309 will slide in the opposite direction in the slot 308, causing the sliding block 306 to slide in the opposite direction in the receiving slot 304. This causes the moving rod 305 to move in the opposite direction until the side of the sliding block 306 contacts the inner wall of the receiving slot 304. At this time, the side of the sliding block 306 contacts the vertical plate of the connecting block 307, and the bottom surface of the sliding block 306 contacts the horizontal plate of the connecting block 307, thus fixing the position between the two protective frame bodies 1. This not only facilitates the replacement of the protective frame body 1, but also improves the stability between the protective frame body 1 and the cash register display screen.

[0028] Working principle: In use, first, place the protective frame body 1 with the fixed base 302 on one side of the cash register display screen, and make the contact plate 201 on the protective frame body 1 contact the side of the cash register display screen. Then, press the moving rod 305 to move it, causing the sliding block 306 to slide in the receiving groove 304 and the fixed rod 309 to slide in the empty groove 308, causing the spring 310 to contract under force until the spring 310 contracts to its maximum limit. At this time, the sliding block 306 and the movable groove 308 are in contact. 3. There is no overlapping part. Subsequently, the protective frame body 1 with the fixing plate 301 is placed on one side of the cash register display screen, so that the contact plate 201 on the protective frame body 1 contacts the side of the cash register display screen, and the connecting block 307 is inserted into the movable groove 303 and the receiving groove 304. Since the length of the horizontal plate of the connecting block 307 and the distance between the moving rod 305 and the inner side wall of the receiving groove 304 are matched, the horizontal plate of the connecting block 307 does not contact the moving rod 305 until the fixing plate 301 and the fixing seat are in contact. When the opposing surfaces of 302 are in contact, releasing the moving rod 305 will cause the fixed rod 309 to slide in the opposite direction within the slot 308 under the elastic force of the spring 310. This will cause the sliding block 306 to slide in the opposite direction within the receiving slot 304, and the moving rod 305 to move in the opposite direction until the side of the sliding block 306 contacts the inner wall of the receiving slot 304. At this point, the side of the sliding block 306 contacts the vertical plate of the connecting block 307, and the bottom surface of the sliding block 306 contacts the horizontal plate of the connecting block 307, thus adjusting the position between the two protective frame bodies 1. The protective frame body 1 is fixed, and by setting the buffer block 202, the protective frame body 1 will move when it is hit by an external object, causing the buffer block 202 to deform under the force and automatically adapt to tilting. The force generated when the buffer block 202 deforms can cancel out the impact force, thereby playing a role in buffering the cash register display screen. Since the buffer block 202 has an arc-shaped structure, it can not only ensure the stability of the position of the protective frame body 1 and the contact plate 201, but also automatically adapt to the direction of the force and tilt.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
