Technical Field
[0001] This utility model relates to the field of automotive repair tools, specifically a device for non-destructive removal of automotive windshields. Background Technology
[0002] Utility model patent CN217620240U discloses a device for disassembling car windshields. In use, this device utilizes a drive mechanism, where a drive motor rotates a rotating rod clockwise, causing two moving tubes to approach each other. A clamping mechanism then uses a moving plate to move a clamping rod, which, through multiple suction cups, simultaneously clamps the car door and windshield, effectively securing them in place. This not only facilitates manual removal of the windshield but also prevents it from detaching during disassembly. Furthermore, a suction mechanism, while the two moving plates approach each other, also moves air pipes. Simultaneously, a piston draws air from the suction cups through the clamping rod and moving plates into the air pipes, allowing the suction cups to adhere more tightly to the car door and windshield, enhancing the fixation effect.
[0003] The current device for disassembling car windshields relies entirely on a fixed disassembly table. It is only suitable for operation when the windshield and the car door are placed on the table. It cannot directly remove the windshield in its installed state on the vehicle. Therefore, we propose a non-destructive removal device for car windshields. Utility Model Content
[0004] The purpose of this invention is to provide a non-destructive windshield removal device for automobiles, so as 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 non-destructive windshield removal device includes four glass suction cups that adhere to the outside of the windshield and four connecting rods for connecting two adjacent glass suction cups. Each glass suction cup includes a suction cup assembly and a connecting assembly mounted on top of the suction cup assembly. The suction cup assembly includes an outer cover and a silicone suction cup fitted onto the bottom of the outer cover. The top of the silicone suction cup has a threaded post that penetrates the outer cover and has a separator fixed in the middle. An adjusting handle is threadedly connected to the threaded post between the separator and the top of the outer cover. The connecting assembly includes an end seat fitted onto the top of the threaded post. A pair of first sleeve posts are fixed at the top of the outer side of the end seat, and a pair of second sleeve posts are fixed at the bottom of the outer side of the end seat. A shank bolt is threadedly connected to the outer circumferential surface of the first and second sleeve posts for locking the connecting rods. A locking handle for limiting the connection assembly is threadedly connected to the top of the threaded post.
[0007] Preferably, the threaded post is made of metal, and the silicone suction cup is fixed to the bottom end of the threaded post using an encapsulation process. When the silicone suction cup is attached to the windshield of the car and the adjusting handle is tightened, the adjusting handle drives the threaded post to move upward in a straight line under the action of the thread, so that a negative pressure is formed between the silicone suction cup and the windshield of the car.
[0008] In this setup, the metal threaded post provides stable support, and the rubber coating process ensures a firm connection between the silicone suction cup and the threaded post. The negative pressure can be controlled by adjusting the handle, enabling the silicone suction cup to stably adhere to the glass.
[0009] Preferably, a vertical sleeve hole is provided at the middle position of the end seat, and the top end of the threaded column passes through the sleeve hole. When the locking handle is tightened, the locking handle presses the end seat against the top end of the separator.
[0010] In this configuration, the sleeve provides a through channel for the threaded post, and the pressing action of the locking handle can fix the position of the end seat, ensuring a stable connection between the connecting assembly and the suction cup assembly.
[0011] Preferably, both the first and second sets of columns are hollow cylindrical structures, and the end of the connecting rod can extend into the first or second set of columns.
[0012] In this setup, the first and second sets of columns in the hollow structure can accommodate the ends of the connecting rod, providing installation space for the connection between the connecting rod and the glass suction cup.
[0013] Preferably, the two first sets of posts are symmetrically distributed on the end seat from left to right, and the two second sets of posts are symmetrically distributed on the end seat from front to back. The axis of the first set of posts is perpendicular to the axis of the second set of posts, and the first set of posts and the second set of posts are staggered in the vertical direction.
[0014] In this setup, the symmetrically distributed sleeves facilitate the connection of adjacent glass suction cups, and the vertical and staggered design prevents interference when the connecting rods cross.
[0015] Preferably, the first end of the shank bolt is a shank portion and the second end is a threaded rod portion, and the threaded rod portions of several shank bolts are respectively threadedly connected to the first sleeve and the second sleeve.
[0016] In this configuration, the lever part allows for easy manual operation of the bolt with handle, while the threaded rod part can be securely connected to the sleeve post to lock the connecting rod.
[0017] Preferably, the connecting rod includes end rods at both ends and a protruding rod in the middle, the protruding rod protruding upward and parallel to the end rods, and the connecting rod can be inserted into the first sleeve or the second sleeve;
[0018] In this setup, the end rod can be inserted into the sleeve to achieve connection, and the upward-protruding rod can avoid interference from the curved surface of the glass, while also serving as a grip for convenient operation.
[0019] Preferably, a plurality of positioning holes are evenly spaced along the axial direction of the end rod on the outer surface of the end rod. The positioning holes pass through the end rod. By inserting the threaded part of the shank bolt into the positioning hole, the end rod can be positioned in the first sleeve or the second sleeve.
[0020] In this configuration, the positioning hole engages with the shank bolt to adjust the length of the end rod extending into the sleeve column, thus adapting to windshields of different sizes and enhancing the device's versatility.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This non-destructive windshield removal device uses four independent glass suction cups and four connecting rods to form an assemblable structure. It does not rely on a fixed dismantling table and can be directly attached to the outside of the windshield in the original position of the vehicle, adapting to real vehicle operation scenarios.
[0023] 2. This non-destructive windshield removal device for automobiles has an end rod on the connecting rod that engages with a bolt with a handle through a positioning hole. The length can be flexibly adjusted along the first set of columns and the second set of columns, and the spacing between adjacent suction cups can be adapted to the size of the windshield of different models, thus improving the versatility of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0033] Please see Figures 1-5 The non-destructive removal device for automotive windshields includes four glass suction cups 100 that are attached to the outside of the automotive windshield and four connecting rods 200 for connecting two adjacent glass suction cups 100. The four glass suction cups 100 and the four connecting rods 200 are combined to form a flexibly assembled structure that does not rely on a fixed workbench and can directly operate the windshield on the vehicle in situ. The glass suction cup 100 includes a suction cup assembly 110 and a connecting assembly 120 installed on the top of the suction cup assembly 110.
[0034] like Figure 2 and Figure 3As shown, in this utility model, the suction cup assembly 110 includes an outer cover 111 and a silicone suction cup 112 fitted onto the bottom of the outer cover 111. The outer cover 111 protects the upper structure of the silicone suction cup 112, preventing damage to the silicone suction cup 112 due to collisions during operation. A threaded post 1121 is provided at the top of the silicone suction cup 112. The threaded post 1121 is made of metal. The silicone suction cup 112 is fixed to the bottom end of the threaded post 1121 using a coating process. This coating process ensures that the silicone suction cup 112 and the threaded post 1121 form a stable whole, guaranteeing the stability of both. It will not detach under force; the threaded column 1121 is connected to the adjusting handle 1123 by an external thread. When the silicone suction cup 112 is attached to the windshield of the car and the adjusting handle 1123 is tightened, the adjusting handle 1123 drives the threaded column 1121 to move upward in a straight line under the action of the thread, so that a negative pressure is formed between the silicone suction cup 112 and the windshield of the car. This structure can achieve adsorption without external air tubes, which simplifies the overall structure of the device. Moreover, the formation of negative pressure can be precisely controlled by adjusting handle 1123 to adapt to the needs of different adsorption forces.
[0035] like Figures 2-4 As shown, specifically, the connecting assembly 120 includes an end seat 121 sleeved on the top of the threaded post 1121. The end seat 121 provides a mounting base for the first sleeve post 122 and the second sleeve post 123, enabling the connecting assembly 120 to form a stable connection with the suction cup assembly 110. A vertical sleeve hole 1211 is opened at the middle position of the end seat 121, through which the top end of the threaded post 1121 passes. The sleeve hole 1211 provides a through channel for the threaded post 1121, ensuring that the threaded post 1121 can smoothly drive the silicone suction cup 112 to move. The threaded post 1121 passes through the outer cover 111 and a partition seat 112 is fixed in the middle. 2. The partition seat 1122 limits the adjustment handle 1123 and provides a support base for the end seat 121. The adjustment handle 1123 is located on the threaded post 1121 between the partition seat 1122 and the top of the outer cover 111. The top of the threaded post 1121 is threadedly connected to a locking handle 130 for limiting the connection assembly 120. When the locking handle 130 is tightened, the locking handle 130 presses the end seat 121 against the top of the partition seat 1122. Through the pressing action of the locking handle 130, the position of the end seat 121 on the threaded post 1121 can be fixed to prevent the connection assembly 120 from loosening during operation.
[0036] like Figures 2-4As shown, furthermore, a pair of first-set posts 122 are fixed at the top position of the outer side of the end seat 121, and a pair of second-set posts 123 are fixed at the bottom position of the outer side of the end seat 121. Both the first-set posts 122 and the second-set posts 123 are hollow cylindrical structures, and the hollow structure provides space for the insertion of the connecting rod 200. The two first-set posts 122 are symmetrically distributed on the end seat 121 from left to right, and the two second-set posts 123 are symmetrically distributed on the end seat 121 from front to back. The axis of the first-set posts 122 and the axis of the second-set posts 123 are symmetrically distributed. The first set of columns 122 and the second set of columns 123 are vertically staggered. This vertical and staggered distribution ensures that when two adjacent glass suction cups 100 are connected using the connecting rod 200, the intersecting parts of the two connecting rods 200 on the glass suction cup 100 will not interfere with each other. The end of the connecting rod 200 can extend into the first set of columns 122 or the second set of columns 123. Through cooperation with the columns, the connecting rod 200 is connected to the glass suction cup 100, thereby combining multiple glass suction cups 100 into an integral structure.
[0037] like Figure 4 and Figure 5 As shown, in addition, the outer peripheral surfaces of the first set of posts 122 and the second set of posts 123 are threaded with shank bolts 124. The shank bolts 124 are used to lock the connecting rod 200. The shank bolts 124 can be screwed into the inside of the post to fix the connecting rod 200. The first end of the shank bolt 124 is a handle part and the end is a threaded rod part. The threaded rod parts of several shank bolts 124 are respectively threaded to the first set of posts 122 and the second set of posts 123. The handle part makes it easy for the operator to manually turn the bolt, and the threaded rod part ensures the stability of the connection with the post. The connecting rod 200 includes end rods 210 at both ends and a protruding rod 220 in the middle. The end rod 200 can be inserted into the first sleeve 122 or the second sleeve 123. The end rod 210 can extend into the sleeve to achieve connection. The protruding rod 220 provides a gripping point for operation. A number of positioning holes 211 are evenly spaced along the axial direction of the end rod 210 on the outer surface of the end rod 210. The positioning holes 211 pass through the end rod 210. By inserting the threaded part of the shank bolt 124 into the positioning hole 211, the end rod 210 can be positioned in the first sleeve 122 or the second sleeve 123. The positioning hole 211 cooperates with the shank bolt 124 to adjust the length of the end rod 210 extending into the sleeve, thereby adapting to windshields of different sizes and improving the versatility of the device.
[0038] like Figure 1 and Figure 5As shown, it is worth noting that the protruding rod 220 protrudes upward and is parallel to the end rod 210. The upward protruding rod 220 can avoid the curved surface of the car windshield, avoid interference, and prevent the connecting rod 200 from contacting the glass surface and causing scratches. In addition, the protruding rod 220 can be used as a gripping part for the operator. By pulling the connecting rod 200 at the protruding rod 220, the connecting rod 200 can simultaneously drive the two glass suction cups 100 at both ends. This allows one side of the car windshield to be subjected to force simultaneously during disassembly, preventing the car windshield from breaking due to uneven force during disassembly. By applying force synchronously, the risk of glass breakage is reduced, and the purpose of non-destructive disassembly is achieved.
[0039] In this embodiment, the non-destructive removal device for car windshields is used by attaching the silicone suction cups 112 of the four glass suction cups 100 to the four corners of the outer side of the car windshield, tightening the adjusting handle 1123 to create negative pressure between the silicone suction cups 112 and the glass to complete the adsorption; then, according to the glass size, adjust the length of the end rods 210 at both ends of the connecting rod 200 extending into the first set of posts 122 or the second set of posts 123 of the adjacent glass suction cups 100, insert the threaded rod part with the shank bolt 124 into the corresponding positioning hole 211 to fix the connecting rod 200; next, tighten the locking handle 130 to ensure that the connecting component 120 is firmly positioned on the threaded post 1121; finally, the operator holds the protruding rod 220 and slowly pulls the connecting rod 200 to evenly apply force to both sides of the glass, gradually removing the windshield from the vehicle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
