Description

Technical Field

[0001] This utility model belongs to the field of glass protection technology, specifically, it relates to a device for preventing glass corner breakage. Background Technology

[0002] Tempered glass refers to glass with compressive stress on its surface, also known as reinforced glass. It is a type of prestressed glass that is strengthened through tempering. To improve its strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external forces, this surface stress is first neutralized, thereby increasing its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts.

[0003] Chinese patent CN212023561U discloses a protective device for preventing tempered glass from cracking at the edges and corners. It includes two hinged side plates, with a flange vertically fixed at the top and bottom of each side plate. Several threaded holes are drilled through the flange, and studs are inserted into these holes. A winding drum is connected to one end of each stud facing the side plate, and a protective pad is wound inside the winding drum. One end of the protective pad extends outward through the outer wall of the winding drum and is connected to a limiting plate. A suction cup strip is located at the bottom of the limiting plate for adsorbing and fixing the protective pad to the upper and lower surfaces of the tempered glass when unfolded. Several suction cup strips are arranged in an array on adjacent sides of the two side plates for adsorbing and fixing the tempered glass edges. The above-mentioned prior art requires tools to rotate the studs to move the protective pad, which is cumbersome and inflexible, and the entire device cannot be folded up, occupying a large space when not in use.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device to prevent glass corner breakage, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A device for preventing glass corner breakage includes a bottom guard plate and a side guard plate. The bottom guard plate has a bottom guard plate mounting groove on its surface, and the side guard plate has a side guard plate mounting groove on its surface. A bottom guard plate fixing structure groove is formed on one side of the bottom guard plate, and a side guard plate fixing structure groove is formed on one side of the side guard plate. Fixing structures are installed inside both the bottom guard plate fixing structure groove and the side guard plate fixing structure groove. An extension shaft is fixedly connected to the bottom of the side guard plate, and a rotating shaft is horizontally installed through the center of the extension shaft, with both ends of the rotating shaft passing through the left and right sides of the bottom guard plate.

[0008] Optionally, both the bottom guard plate mounting groove and the side guard plate mounting groove have through holes. A connecting rod is inserted into the hole, and a sleeve is fitted onto the surface of the connecting rod. A torsion spring is provided on one side of the sleeve, and a bent rod is fixedly connected to the front of the sleeve. A protective sleeve is fitted onto the front end of the bent rod.

[0009] Optionally, the bottom of the bottom guard plate and the side guard plate are provided with bosses at the positions corresponding to the slots in the bottom guard plate fixing structure and the slots in the side guard plate fixing structure.

[0010] Optionally, an external soft pad is provided on the bottom of the bottom guard plate corresponding to the outer ring of the boss.

[0011] Optionally, clearance grooves are provided at corresponding positions on the bottom of the bottom guard plate and the side guard plate.

[0012] Optionally, both the bottom guard plate mounting groove and the side guard plate mounting groove are provided with protective pad one and protective pad two.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. This anti-glass corner breakage device fixes the glass by placing it into the installation groove, pulling out the curved rod, and pressing the protective sleeve onto the glass surface through the torsion spring. The overall operation is simple and quick. The protective sleeve and protective pad adhere to the glass to reduce the transmission of external vibrations and protect the glass, preventing it from breaking due to impacts at the corners.

[0015] 2. This anti-glass corner breakage device adjusts the angle between the bottom guard plate and the side guard plate by rotating the extension shaft. The two guard plates remain perpendicular to each other to fit the edge of rectangular glass. Changing the angle can also fit and protect other irregularly shaped glass. When the device is not in use, the bottom guard plate is rotated to fit the bottom of the side guard plate, which reduces the overall space occupied and makes it easier to store.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a device to prevent glass corner breakage, including: a bottom guard plate 1 and a side guard plate 2.

[0029] like Figure 1 , 3 As shown, in this embodiment, the bottom guard plate 1 has a bottom guard plate mounting groove 101 on its surface, and the side guard plate 2 has a side guard plate mounting groove 201 on its surface. A bottom guard plate fixing structure groove 102 is formed on one side of the bottom guard plate 1, and a side guard plate fixing structure groove 202 is formed on one side of the side guard plate 2. Fixing structures 3 are installed inside both the bottom guard plate fixing structure groove 102 and the side guard plate fixing structure groove 202. An extension shaft 4 is fixedly connected to the bottom of the side guard plate 2. A rotating shaft 401 is horizontally installed through the center of the extension shaft 4. 1. Both ends pass through the left and right sides of the bottom guard plate 1; wherein, the extension shaft 4 extends obliquely downward from the bottom of the side guard plate 2, so that both can rotate around the pivot 401 as the center, inserting the side of the glass into the bottom guard plate mounting groove 101 and the side guard plate mounting groove 201, adjusting the angle between the bottom guard plate 1 and the side guard plate 2 so that they can fit completely, whether it is conventional rectangular glass or irregular glass, it can fit to protect the corner position, and press it on the glass by rotating the fixing structure 3 to completely fix it in the mounting groove.

[0030] like Figure 1 , 2 As shown, in this embodiment, holes are provided through the side walls of both the bottom guard plate mounting groove 101 and the side guard plate mounting groove 201. A connecting rod 301 is inserted into the hole, and a sleeve 302 is fitted onto the surface of the connecting rod 301. A torsion spring 303 is provided on one side of the sleeve 302, and a bent rod 304 is fixedly connected to the front of the sleeve 302. A protective sleeve 305 is fitted onto the front end of the bent rod 304. The bent rod 304 is symmetrical from left to right, extending from the corresponding bottom guard plate fixing structure groove 102, extending obliquely downwards, reaching the bottom of the bottom guard plate 1, bending towards the bottom surface and extending into the bottom surface. Finally, one end of the two bent rods 304 is bent and connected, and the other end is fixedly connected to the sleeve 302. The sleeve 302 is fitted onto the connecting rod 301 with a gap between them, and the torsion spring 303 is inserted into the gap. One end is fixed in the hole at the end of the connecting rod 301. Both sleeves 302 are provided with torsion springs 303 facing the holes. The torsion springs 303 apply force to the sleeves 302, pushing the bent rod 304 towards the bottom guard plate mounting groove 101, so that the protective sleeve 305 on the bent rod 304 fits against the internal tempered glass to fix it. The protective sleeve 305 prevents the bent rod 304 from contacting the glass and causing scratches. The fixing structure 3 on the side guard plate mounting groove 201 is exactly the same as the fixing structure 3 in the bottom guard plate mounting groove 101. The four fixing structures 3, two on the bottom plate 1 and two on the side guard plate 2, are used to completely fix the glass corners in multiple directions. Similarly, protective devices are also installed at the other three corners to protect all corners.

[0031] like Figure 3 As shown, in this embodiment, the bottom of the bottom guard plate 1 and the side guard plate 2 are provided with protrusions 6 at the positions corresponding to the bottom guard plate fixing structure slot 102 and the side guard plate fixing structure slot 202. The protrusions 6 are used to hold the bent rod 304. The connection of the bent rod 304 is close to the edge of the protrusion 6. By locking the bent rod 304, the sleeve 302 is able to overcome the torsion spring 303 and be stuck on the outside, without affecting the glass insertion into the bottom guard plate mounting slot 101 and the side guard plate mounting slot 201.

[0032] like Figure 3 , 5 As shown, in this embodiment, the bottom of the bottom guard plate 1 is provided with an external soft pad 7 around the outer ring of the protrusion 6; wherein, the protrusion 6 protrudes from the bottom of the bottom guard plate 1, and by providing the external soft pad 7, its height is higher than the protrusion 6. When the bottom guard plate 1 is placed on the ground, the external soft pad 7 lifts the bottom guard plate 1, preventing the protrusion 6 from contacting the ground and causing unevenness of the bottom surface, which would affect the balance of the entire glass when placed on the ground, thereby preventing shaking.

[0033] like Figure 3 , 5As shown, in this embodiment, the bottom guard plate 1 and the side guard plate 2 are provided with clearance grooves 5 at corresponding positions on the bottom. The side guard plate 2 is rotated by the pivot 401 and fits against the bottom surface of the bottom guard plate 1 to fold up the device, reducing the floor space for easy storage. Before folding, the bent rod 304 of the fixing structure 3 is folded onto the bottom boss 6 and fastened. After the bottom guard plate 1 and the side guard plate 2 are fitted together, the clearance grooves 5 at corresponding positions prevent the boss 6 and the bent rod 304 from colliding with the bottom of the bottom guard plate 1 or the side guard plate 2, facilitating the fitting of the two.

[0034] like Figure 4 As shown, in this embodiment, both the bottom guard plate mounting groove 101 and the side guard plate mounting groove 201 are provided with protective pad 1 8 and protective pad 2 9. Among them, protective pad 1 8 is placed vertically and attached to the side of the bottom guard plate mounting groove 101, opposite to the side of the bottom guard plate fixing structure slot 102. Similarly, protective pad 1 8 is also provided on the side of the side guard plate mounting groove 201, opposite to the side of the side guard plate fixing structure slot 202. The front is pressed by the protective sleeve 305 to attach the back of the glass to protective pad 1 8. Protective pad 2 9 is attached to the bottom of the bottom guard plate mounting groove 101 and the side guard plate mounting groove 201, and is attached to the bottom of the glass for support. The two protective pads reduce external vibration and reduce damage caused by collisions at the glass edges during transportation.

[0035] Working principle: The bottom guard plate 1 can rotate around the pivot 401 of the extension shaft 4, thereby adjusting its angle with the side guard plate 2. The two can fit the edge of the rectangular glass by maintaining perpendicularity, or they can fit and protect other irregularly shaped glass by changing the angle. Insert the two sides of the glass into the bottom guard plate mounting groove 101 and the side guard plate mounting groove 201 respectively. Flip all the fixing structures 3 and rotate the bent rod 304 off the boss 6. The torsion spring 303 pushes the sleeve 302 to make the bent rod 304 rotate on the connecting rod 301 until the protective sleeve 305 on the bent rod 304 automatically fits on the front of the glass. Push the back of the glass to fit the protective pad 8. Multiple fixing structures 3 fix the glass, thereby protecting the glass corners. After use, the device can be rotated to make the bottom of the bottom guard plate 1 fit and parallel to the bottom of the side guard plate 2, thereby reducing the unfolded volume of the device and making it easier to store.
