[0001] The utility model relates to the technical field of display frames, in particular to an anti-theft display frame. Background Art

[0002] A display frame is a frame used to hold exhibits. The front door is usually made of transparent glass or transparent acrylic. This protects the exhibits and does not block the information displayed by the exhibits. The exhibits include posters, leaflets, photos, etc.

[0003] The steps of using the display frame are generally as follows: opening the front switch door of the display frame, attaching the promotional poster inside the display frame, and finally closing the front switch door. However, the existing display frame has some defects when used, such as:

[0004] Promotional posters are usually made of paper. After the promotional posters are attached to the inside of the display frame and before the door is closed, the upper part of the promotional poster may bend and fall downward, causing the corners of the upper part of the promotional poster to bend, thereby reducing the quality of attachment. Summary of the invention

[0005] The utility model provides an anti-theft display frame to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is achieved in this way:

[0007] An anti-theft display frame includes an outer frame, an upper pull-up frame and a lower pull-up frame;

[0008] Outer frame: The interior of the outer frame is connected vertically, and the upper and lower ends of the outer frame are respectively interspersed with an upper pull-up frame and a lower pull-up frame that can be moved up and down;

[0009] Upper pull-up frame: A first clamp is installed in the lower end of the upper pull-up frame;

[0010] Pull-down rack: a second clamp is installed in the upper end of the pull-down rack, an exhibit is fixed between the first clamp and the second clamp, a connecting piece is installed between the upper side of the pull-down rack and the inner lower side of the outer frame, and when the pull-down rack moves into the upper end of the outer frame, it is fixed in the upper end of the outer frame through the connecting piece;

[0011] By adopting the above technical solution, the upper end of the exhibit is fixed by the upper pull-up frame, and the lower end of the exhibit is fixed by the lower pull-up frame. When the lower pull-up frame moves downward due to its own gravity, the exhibit can be straightened downward to ensure the flatness of the exhibit and avoid wrinkles at the corners of the exhibit. When the lower pull-up frame moves from the upper end of the outer frame to the lower end, the exhibit can fall downward into the outer frame for display.

[0012] Preferably, the first clamp comprises a slot, a first spring and a push rod, the slot is arranged at the center of the lower side of the upper pull-up frame, the push rod is movably passed through the side of the slot, the upper end of the exhibit is clamped between the other side of the slot and the end of the push rod, and the first spring is fixed between the end of the push rod and the side of the upper pull-up frame;

[0013] By adopting the above technical solution, the first spring pulls the push rod, and the push rod is close to the side of the slot, so that the end of the push rod and the side of the slot clamp the upper end of the exhibit, thereby fixing the upper end of the exhibit in the upper pull frame.

[0014] Preferably, the second clamp comprises a clamping plate, a second magnet, a roller and a second spring. There are two rollers which rotate respectively in the two ends of the upper half of the lower pull-up frame. Clamping plates are movably inserted in the two rollers. The two clamping plates are symmetrically arranged. A second spring is fixed between the end of the clamping plate and the inner side of the roller. A second magnet is fixed in the side of the two clamping plates close to each other. The two second magnets attract each other with opposite polarities. The lower end of the exhibit is clamped between the two clamping plates and located between the two second magnets.

[0015] By adopting the above technical solution, the second spring pushes the two clamps to approach each other, and the two second magnets attract each other magnetically and also make the two clamps approach each other. The two clamps approach each other to clamp the lower end of the exhibit, so as to fix the exhibit in the pull-down rack;

[0016] When the professional pulls the exhibit upwards to replace the exhibit, the exhibit pulls the clamping plate upwards to rotate the two rollers, so that the clamping plate releases the exhibit, thereby forcibly pulling the exhibit upwards.

[0017] Preferably, the side where the two clamps are close to each other and the side where the two second magnets are close to each other are both provided with friction-increasing grooves in a linear array;

[0018] By adopting the above technical solution, the friction between the clamping plate and the exhibit is increased by using the friction increasing groove, and the friction between the second magnet and the exhibit is increased, thereby ensuring the stability of the exhibit in the pull-down rack.

[0020] By adopting the above technical solution, when the pull-down rack reaches the upper end of the outer frame, the first magnet and the third magnet attract each other with opposite charges, so that the pull-down rack is fixed in the upper end of the outer frame, waiting for the new exhibit to be re-inserted into the pull-down rack, thereby preventing the pull-down rack from falling off from the lower end of the old exhibit without inserting the new exhibit.

[0021] Preferably, a rotating plate is rotated on the front side of the outer frame through a rotating shaft, a top plate is integrally formed on the rear side of the lower end of the rotating plate, and triangular grooves are provided on the upper side of the inner part of the outer frame and the upper side of the lower pull-down frame, and when the rotating plate rotates backward, the top plate is inserted between the triangular grooves of the outer frame and the lower pull-down frame;

[0022] By adopting the above technical solution, after a new exhibit is inserted into the pull-down rack, the rotating plate can be pressed backward to insert the top plate between the outer frame and the triangular groove of the pull-down rack, so that the top plate can forcefully push the pull-down rack downward, so that the pull-down rack pulls the exhibit to fall freely.

[0023] Preferably, a handle is provided inside the upper end of the upper pull frame;

[0024] By adopting the above technical solution, the handle can conveniently pull the upper pull-up frame upwards.

[0025] Preferably, a roller is rotated by a shaft in the upper end of the outer frame;

[0026] By adopting the above technical solution, the roller prevents the outer frame from scratching the exhibit, and the roller rotates along with the up and down movement of the exhibit to protect the exhibit.

[0027] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0028] The utility model utilizes an upper pull-up frame to fix the upper end of an exhibit, and utilizes a lower pull-up frame to fix the lower end of an exhibit; when the lower pull-up frame moves downward due to its own gravity, the exhibit can be straightened downward to ensure the flatness of the exhibit and avoid wrinkles at the corners of the exhibit; when the lower pull-up frame moves from the upper end of the outer frame to the lower end, the exhibit can be dropped downward into the outer frame for display, ensuring that the exhibit is vertically attached to the outer frame, thereby improving the display quality of the exhibit.

Example

[0037] See also Figure 3 and Figure 4 , auxiliary reference Figure 1 and Figure 2 , an anti-theft display frame, comprising an outer frame 1, an upper pull-up frame 7 and a lower pull-up frame 18;

[0038] Outer frame 1: The front and rear walls of the outer frame 1 are made of transparent acrylic plates, and the upper, lower, left and right sides of the outer frame 1 are made of silver-plated aluminum frames. The upper and lower sides of the outer frame 1 are hollowed out so that the interior is connected from top to bottom. The upper and lower ends of the outer frame 1 are respectively interspersed with an upper pull-up frame 7 and a lower pull-up frame 18, and a roller 12 is rotated in the upper end of the outer frame 1 through a rotating shaft;

[0039] Upper pull-up frame 7: A first clamp is installed in the lower end of the upper pull-up frame 7, and a handle 9 is provided in the upper end of the upper pull-up frame 7. In order to ensure that the upper pull-up frame 7 is not pulled out by non-special personnel, a lock can also be installed between the upper pull-up frame 7 and the outer frame 1;

[0040] Pull-down rack 18: A second clamp is installed in the upper end of the pull-down rack 18, and an exhibit 3 is fixed between the first clamp and the second clamp. A connecting piece is installed between the upper side of the pull-down rack 18 and the inner lower side of the outer frame 1. When the pull-down rack 18 moves into the upper end of the outer frame 1, it is fixed in the upper end of the outer frame 1 through the connecting piece. The width of the pull-down rack 18 gradually decreases from the middle end to the lower end, and the width of the inner bottom end of the outer frame 1 gradually decreases from top to bottom, so that the pull-down rack 18 is supported in the bottom end of the outer frame 1 and can move freely upward.

[0041] In this embodiment, the first clamp includes a slot 8, a first spring 10 and a push rod 11. Figure 3 A slot 8 is provided at the center of the lower side of the upper pull-up frame 7, a push rod 11 is movably passed through the side of the slot 8, the upper end of the exhibit 3 is clamped between the other side of the slot 8 and the end of the push rod 11, and a first spring 10 is fixed between the end of the push rod 11 and the side of the upper pull-up frame 7.

[0042] In this embodiment, the second clamp includes a clamping plate 13, a second magnet 14, a roller 15 and a second spring 17. Figure 4 There are two rollers 15 that rotate respectively at the two ends of the upper half of the lower pull-up frame 18. A clamping plate 13 is movably inserted in each of the two rollers 15. The two clamping plates 13 are symmetrically arranged. A second spring 17 is fixed between the end of the clamping plate 13 and the inner side of the roller 15. A second magnet 14 is fixed in the side where the two clamping plates 13 are close to each other. The two second magnets 14 attract each other with opposite poles. The lower end of the exhibit 3 is clamped between the two clamping plates 13 and located between the two second magnets 14. A linear array of friction-increasing grooves is provided on the side where the two clamping plates 13 are close to each other and on the side where the two second magnets 14 are close to each other.

[0043] In this embodiment, the connecting member is mainly composed of a first magnet 6 and a third magnet 16. Figure 5 The first magnet 6 is fixed to the upper side of the inner part of the outer frame 1, and the third magnet 16 is fixed to the upper side of the lower pull-down frame 18. When the lower pull-down frame 18 reaches the upper end of the outer frame 1, the first magnet 6 and the third magnet 16 are attracted by opposite sexes, that is, the lower pull-down frame 18 is fixed in the upper end of the outer frame 1 by the opposite sexes of the first magnet 6 and the third magnet 16.

[0044] A rotating plate 2 is rotated on the front side of the outer frame 1 through a rotating shaft, and a top plate 4 is integrally formed on the rear side of the lower end of the rotating plate 2. In order to facilitate the top plate 4 to be inserted between the outer frame 1 and the lower pull-down frame 18 to push the lower pull-down frame 18 downward, triangular grooves 5 are provided on the upper side of the inner part of the outer frame 1 and the upper side of the lower pull-down frame 18. When the rotating plate 2 rotates backward, the top plate 4 is inserted between the triangular grooves 5 of the outer frame 1 and the lower pull-down frame 18, that is, the lower pull-down frame 18 is pushed downward by the top plate 4 to move the lower pull-down frame 18 away from the upper end of the outer frame 1.

[0045] Working principle:

[0046] When in use, the upper pull-up frame 7 is pulled out upward by the handle 9, so that the upper pull-up frame 7 drives the exhibit 3 to be pulled out of the outer frame together, and the exhibit 3 pulls the lower pull-up frame 18 upward until the lower pull-up frame 18 reaches the upper end of the outer frame 1. At this time, the first magnet 6 and the third magnet 16 are attracted by opposite sexes, so that the lower pull-up frame 18 is fixed to the upper end of the outer frame 1, and then the exhibit 3 is forcibly pulled upward, so that the exhibit 3 rotates the roller 15 by pulling the clamping plate 13, so that the two clamping plates 13 release the exhibit 3, and the old exhibit 3 can be removed, and then the ejector rod 11 is pulled to form a gap between the end of the ejector rod 11 and the side of the slot 8, and the upper end of the new exhibit 3 is inserted into the gap between the ejector rod 11 and the side of the slot 8, and the ejector rod 11 is released. The spring 10 pulls the top rod 11 to make the top rod 11 and the side of the card slot 8 approach each other to clamp the upper end of the exhibit 3, and then the lower end of the exhibit 3 is inserted downward between the two clamping plates 13 and the clamping plate 13 is pushed downward, so that the roller 15 rotates back to its original position in the opposite direction. At this time, the second spring 17 pushes the clamping plate 13 to make the two clamping plates 13 approach each other to clamp the lower end of the exhibit 3, and the two second magnets 14 attract each other with opposite sexes to further clamp the lower end of the exhibit 3. Finally, the rotating plate 2 is pressed, and the rotating plate 2 drives the top plate 4 to rotate, so that the top plate 4 is inserted into the triangular groove 5 and forcibly pushes the lower pull-down frame 18 downward, forcing the first magnet 6 and the third magnet 16 to separate, and the lower pull-down frame 18 falls freely to automatically pull the new exhibit 3 into the outer frame 1.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
