Description

Technical Field

[0001] This utility model relates to the technical field of paper corner protector structures, specifically a U-shaped paper corner protector. Background Technology

[0002] Paper corner protectors, also known as edge protectors, are one of the most popular packaging products internationally, used to replace wooden packaging and other bulky packaging methods. Paper corner protectors are made by laminating multiple sheets of kraft paper and then shaping and pressing them using a corner protector machine. They are mainly available in L-shape and U-shape. When used for stacking goods, they can strengthen the edge support of the packaged goods and protect its overall packaging strength. They are a green and environmentally friendly packaging material that can replace wood and is 100% recyclable.

[0003] Conventional U-shaped paper corner protectors are suitable for transport protection of rectangular frames. However, the U-shaped corner protectors only snap onto the rectangular corners, making them prone to falling off during transport due to collisions, thus affecting the quality of the goods after transport. In addition, some U-shaped corner protectors are fixed with screws, which involves multiple installation and disassembly steps, thus affecting the installation efficiency of the U-shaped corner protectors. Therefore, those skilled in the art have proposed a U-shaped paper corner protector to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a U-shaped paper corner protector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A U-shaped paper corner protector includes a corner protector plate with a removable elastic protective sleeve. The corner protector plate has mounting grooves at both its top and bottom, and a pressing and suction assembly is installed within each groove. The pressing and suction assembly includes a pressing block and a soft-return spring. A first horizontal plate is connected to the inner walls of both sides of the mounting groove at the end furthest from the elastic protective sleeve. A second horizontal plate is connected to both sides of the pressing block at the end closest to the elastic protective sleeve. The soft-return spring is positioned between the first and second horizontal plates, with its two ends connected to the adjacent ends of the first and second horizontal plates, respectively. A plurality of suction cups are evenly distributed at the end of the pressing block furthest from the elastic protective sleeve.

[0007] As a further improvement of this utility model: two soft-return springs are provided between the first horizontal plate and the second horizontal plate, and the soft-return springs are installed at the corners of the first horizontal plate and the second horizontal plate.

[0008] As a further improvement of this utility model: the length and width of the pressing block are both smaller than the inner length and inner width of the mounting groove, respectively, and the two ends of the pressing block are provided with inner grooves.

[0009] As a further improvement of this utility model: an extended edge is provided at the edge of the suction cup away from the elastic protective sleeve, and the extended edge is integrally formed with the suction cup.

[0010] As a further improvement of this utility model: the top and bottom ends of the corner protector are symmetrically provided with two dovetail grooves, and the inner top and bottom surfaces of the elastic protective sleeve are provided with dovetail block structures that cooperate with the dovetail grooves.

[0011] As a further improvement of this utility model: both sides of the elastic protective sleeve are provided with edging structures, and the inner wall of the edging structure is fitted with the outer wall of the corner protector.

[0012] This utility model has the following advantages: The corner protector is designed with an installation groove and a pressing and adsorption assembly within the groove, allowing for quick installation onto the corner. The pressing and adsorption assembly uses a pressing block to drive a suction cup to adhere to the corner surface. An elastic protective sleeve is then installed around the corner protector, covering the installation groove and ensuring the overall aesthetics of the corner protector structure. Simultaneously, the elastic protective sleeve protects the outer surface of the corner protector from water, oil, and other contaminants. Furthermore, the inner wall of the elastic protective sleeve rests against the end of the pressing block, preventing the soft-return spring on the pressing and adsorption assembly from rebounding, thus ensuring the suction cup is stably adsorbed onto the outer wall of the corner and improving the overall installation stability of the corner protector structure.

[0020] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0021] Example 1: Please refer to Figures 1 to 3 A U-shaped paper corner protector includes a corner protector plate 1. An elastic protective sleeve 3 is detachably installed on the periphery of the corner protector plate 1. The top and bottom of the corner protector plate 1 are provided with mounting grooves 101. A pressing and adsorption component assembly 2 is installed in the mounting groove 101. The pressing and adsorption component assembly 2 includes a pressing block 201 and a soft return spring 204. The inner walls on both sides of the end of the mounting groove 101 away from the elastic protective sleeve 3 are connected to a first horizontal plate 103. The two sides of the pressing block 201 near the elastic protective sleeve 3 are connected to a second horizontal plate 203. The soft return spring 204 is disposed between the first horizontal plate 103 and the second horizontal plate 203. The two ends of the soft return spring 204 are respectively connected to the adjacent ends of the first horizontal plate 103 and the second horizontal plate 203. A plurality of suction cups 202 are evenly distributed on the end of the pressing block 201 away from the elastic protective sleeve 3.

[0022] Please see Figures 1 to 3Two soft-return springs 204 are provided between the first horizontal plate 103 and the second horizontal plate 203. The soft-return springs 204 are installed at the corners of the first horizontal plate 103 and the second horizontal plate 203. The length and width of the pressing block 201 are both smaller than the inner length and inner width of the mounting groove 101, respectively. Both sides of the pressing block 201 are provided with inner grooves 205, which are used to facilitate pinching the pressing block 201 by hand.

[0023] Please see Figure 1 An extended edge 206 is provided at the edge of the suction cup 202 away from the elastic protective sleeve 3. The extended edge 206 is integrally formed with the suction cup 202. The extended edge 206 improves the fit between the end of the suction cup 202 and the outer wall of the corner.

[0024] Example 2: See Figures 1 to 3 Based on Embodiment 1, the corner protector 1 is provided with two dovetail grooves 102 symmetrically at its top and bottom, and the elastic protective sleeve 3 is provided with dovetail block structures 303 that cooperate with the dovetail grooves 102 on its inner top and bottom surfaces.

[0025] Please see Figures 1 to 3 Both sides of the elastic protective sleeve 3 are provided with edge-wrapping structures 302, the inner wall of the edge-wrapping structure 302 is attached to the outer wall of the corner protector 1, the elastic protective sleeve 3 is made of rubber material, and the top and bottom corners of the rear end of the elastic protective sleeve 3 are provided with arc corner structures 301.

[0026] Working principle: When in use, place the corner protector 1 on the corner, press the pressing block 201 to move the pressing block 201, which in turn moves the suction cup 202 and attaches it to the outer wall of the corner. At this time, the return spring 204 is in a compressed state, and the end of the pressing block 201 away from the corner is flush with the outer end wall of the corner protector 1. Then, by inserting the dovetail block structure 303 into the dovetail groove 102, the elastic protective sleeve 3 is quickly installed on the outside of the corner protector 1. The corner protector 1 is protected by the elastic protective sleeve 3. When removing the corner protector 1, remove the elastic protective sleeve 3, pinch the inner groove 205 with your fingers, and pull the pressing block 201 outward to detach the suction cup 202 from the outer wall of the corner.
