Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy subframe technology, specifically to a device for painting ultra-thick nodes on the edge of an aluminum alloy subframe. Background Technology

[0002] The main function of aluminum alloy subframes is to fix and protect the main frame of doors and windows. They help doors and windows better adapt to the irregularities of building structures, improving installation accuracy and stability. In some high-end doors and windows, aluminum alloy subframes can also improve insulation and sealing performance, and help prevent deformation and water seepage caused by thermal expansion and contraction. Special attention needs to be paid to key areas such as: internal and external corners, pipe roots, rainwater outlets, various flashings, expansion joints, deformation joints, construction joints, and through-wall pipes.

[0003] In the existing technology, after prolonged use, aluminum alloy subframe edges are prone to developing excessively thick nodes. These excessively thick nodes require special attention due to internal quality damage. Currently, the treatment of these excessively thick nodes often requires repainting. However, the overall length of the current painting structure cannot be changed, making it inconvenient to paint some high parts, thus limiting its application range. Utility Model Content

[0004] The purpose of this utility model is to provide a painting device for ultra-thick nodes on the edge of an aluminum alloy subframe, in order to solve the problem that the overall length of the painting structure currently used cannot be changed, which makes it inconvenient to paint some high parts and thus limits its application range.

[0005] To achieve the above objectives, a painting device for ultra-thick nodes on the edge of an aluminum alloy subframe is provided, comprising a lower sleeve, a lower fixed sleeve fixed to the top of the lower sleeve, an upper shrinking sleeve sleeved to the top of the lower fixed sleeve, locking holes of equal distance on the sides of both the lower fixed sleeve and the upper shrinking sleeve, a support plate fixed to the top of the upper shrinking sleeve, vertical plates fixed to both ends of the top surface of the support plate, a round rod disposed between the two vertical plates, the round rod extending to the side of the vertical plate, a painting tube sleeved on the outer surface of the round rod, a locking structure disposed on the outer surface of the lower fixed sleeve, the locking structure comprising a locking frame, a rotating rod rotatably connected to the inner wall of the locking hole near the upper end of the lower fixed sleeve, a torsion block fixed to the side of the rotating rod, a compression spring fixed to the outer surface of the rotating rod, a locking block fixed to the side of the rotating rod near the inner wall of the locking frame, a locking groove consistent with the locking block being opened on the side of the locking frame, and the rotating rod extending to the outer side of the locking frame.

[0006] According to the aforementioned aluminum alloy subframe edge ultra-thick node painting device, threaded holes are provided at both ends of the top surface of the round rod, an upper pressure plate is fixed to the top of the round rod, a lower pressure plate is fixed to the bottom of the round rod, the threaded hole passes through the bottom of the lower pressure plate, and a reinforcing screw is threadedly connected to the inner wall of the threaded hole.

[0007] According to the aforementioned aluminum alloy subframe edge ultra-thick node painting device, a placement plate is fixed at the bottom of the lower sleeve, and the bottom of the placement plate is frosted.

[0008] According to the aforementioned aluminum alloy subframe edge ultra-thick node painting device, the number of lock holes opened on the outer side of the lower fixed cylinder and the upper shrink cylinder is the same.

[0009] According to the aforementioned aluminum alloy subframe edge ultra-thick node painting device, the outer surface of the lower sleeve is roughened.

[0010] According to the aforementioned aluminum alloy subframe edge ultra-thick node painting device, the contact surface between the locking frame and the lower fixed cylinder is set as an arc.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to change the overall height of the device, the upper shrinking cylinder is first slid into the lower fixed cylinder. When the upper shrinking cylinder slides to the designated position, the torsion block is rotated, which drives the rotating rod on the side of the torsion block to rotate, thereby driving the locking block on one side of the inner wall of the locking frame to rotate. When the locking block rotates to be parallel to the locking groove, the compression spring will push the locking block out to the outside of the locking groove under the action of the compression spring. At this time, the rotating rod can be moved out from the lock hole, which makes it easier to slide the upper shrinking cylinder into the lower fixed cylinder, thereby achieving the effect of changing the overall height. In addition, by setting the upper pressure plate, the lower pressure plate, and the reinforcing screw, the two ends of the top surface of the round rod can be fixed, thereby reinforcing the paint cylinder sleeved on the outer surface of the round rod. Furthermore, by rotating the reinforcing screw in the opposite direction, the two ends of the top surface of the round rod can be loosened.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] 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 utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a painting device for ultra-thick nodes on the edge of an aluminum alloy subframe, including a lower sleeve 1, a lower fixed sleeve 2 fixed to the top of the lower sleeve 1, an upper shrinking sleeve 3 sleeved on the top of the lower fixed sleeve 2, and locking holes 4 with equal spacing on the sides of both the lower fixed sleeve 2 and the upper shrinking sleeve 3. A support plate 5 is fixed to the top of the upper shrinking sleeve 3, and vertical plates 6 are fixed to both ends of the top surface of the support plate 5. A round rod 7 is arranged between the two vertical plates 6, extending to the side of the vertical plate 6. A painting cylinder 8 is sleeved on the outer surface of the round rod 7. A locking structure is provided on the outer surface of the cylinder 2. The locking structure includes a locking frame 9. A rotating rod 10 is rotatably connected to the inner wall of the upper locking hole 4 of the lower fixed cylinder 2. A torsion block 11 is fixed to the side of the rotating rod 10. A compression spring 12 is fixed to the outer surface of the rotating rod 10. A locking block 13 is fixed to the side of the rotating rod 10 near the inner wall of the locking frame 9. A locking groove 14 with the same shape as the locking block 13 is opened on the side of the locking frame 9. The rotating rod 10 extends to the outer side of the locking frame 9. In the prior art, the edge of the aluminum alloy subframe is prone to wear and tear after prolonged use. Excessively thick joints are prone to occur, and these joints require special attention due to internal quality damage. Currently, the treatment of these joints often involves repainting. However, the current painting structure cannot be altered in its overall length, making it inconvenient to paint high areas and limiting its application. To address this issue, a locking structure can be used. When the overall height of the device needs to be changed, the upper shrinking cylinder 3 is first slid into the lower fixed cylinder 2. When the upper shrinking cylinder 3 reaches the designated position, the torsion block 11 is rotated, causing the rotating rod 10 on the side of the torsion block 11 to rotate. This, in turn, causes the locking block 13 on one side of the inner wall of the locking frame 9 to rotate. When the locking block 13 rotates to be parallel to the locking groove 14, the compression spring 12 pushes the locking block 13 out of the locking groove 14. At this point, the rotating rod 10 can be removed from the lock hole 4, facilitating the sliding of the upper shrinking cylinder 3 into the lower fixed cylinder 2, thereby changing the overall height.

[0021] Both ends of the top surface of the round rod 7 are provided with threaded holes. An upper pressure plate 15 is fixed to the top of the round rod 7, and a lower pressure plate 16 is fixed to the bottom of the round rod 7. The threaded holes pass through the bottom of the lower pressure plate 16, and a reinforcing screw 17 is threadedly connected to the inner wall of the threaded holes. By setting the upper pressure plate 15, the lower pressure plate 16, and the reinforcing screw 17, the two ends of the top surface of the round rod 7 can be fixed, thereby reinforcing the paint cylinder 8 sleeved on the outer surface of the round rod 7. Furthermore, by rotating the reinforcing screw 17 in the opposite direction, the two ends of the top surface of the round rod 7 can be loosened.

[0022] A placement plate 18 is fixed to the bottom of the lower sleeve 1. The bottom of the placement plate 18 is frosted. The frosting of the bottom of the placement plate 18 facilitates the stable placement of the device. The number of locking holes 4 on the outer side of the lower fixed sleeve 2 and the upper shrinking sleeve 3 is the same. The design of the number of locking holes 4 makes it easy to lock the lower fixed sleeve 2 when it is moved down or up through the locking holes 4, avoiding the situation where it cannot be locked after movement. The outer surface of the lower sleeve 1 is roughened. The rough design of the outer surface of the lower sleeve 1 prevents the lower sleeve 1 from slipping when it is picked up. The contact surface between the locking frame 9 and the lower fixed sleeve 2 is set as an arc 19 to facilitate stable contact between the locking frame 9 and the lower fixed sleeve 2.

[0023] Working principle: When the overall height of the device needs to be changed, the upper shrinking cylinder 3 is first slid into the lower fixed cylinder 2. When the upper shrinking cylinder 3 slides to the designated position, the torsion block 11 is rotated, which drives the rotating rod 10 on the side of the torsion block 11 to rotate, thereby driving the locking block 13 on the inner wall of the locking frame 9 to rotate. When the locking block 13 rotates to be parallel to the locking groove 14, the compression spring 12 will push the locking block 13 out to the outside of the locking groove 14. At this time, the rotating rod 10 can be moved out from the lock hole 4, which makes it easier to slide the upper shrinking cylinder 3 into the lower fixed cylinder 2, thereby achieving the effect of changing the overall height. By setting the upper pressure plate 15, the lower pressure plate 16, and the reinforcing screw 17, the two ends of the top surface of the round rod 7 can be fixed, thereby reinforcing the paint cylinder 8 sleeved on the outer surface of the round rod 7. And by rotating the reinforcing screw 17 in the opposite direction, the two ends of the top surface of the round rod 7 can be loosened.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
