When in use, the telescopic drive device drives the movement of the U-shaped bracket at the movable end, and the overall telescopic movement of the spray paint room can be achieved through the scissor-type telescopic connecting rod mechanism, and the movable end can be closed and opened through the rolling shutter device. In the process of retracting the traditional telescopic spray paint room, the tarpaulin on the inside is easily damaged due to the clamping of the U-shaped bracket, which is insufficient. Summary of the invention

[0003] The purpose of the present invention is to address the above-mentioned technical defects of traditional telescopic paint spray booths and provide an improved telescopic paint spray booth, in which a folding support structure is arranged between adjacent U-shaped brackets. The folding support structure can automatically push the tarpaulin to a position away from the U-shaped bracket when the paint spray booth is retracted, thereby effectively avoiding damage to the tarpaulin caused by deformation of the hard structure when the paint spray booth is retracted.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A telescopic spray paint shop comprises a plurality of U-shaped brackets which are slidably arranged on left and right tracks with two legs, the plurality of U-shaped brackets are connected by a scissor-type telescopic connecting rod mechanism, a tarpaulin is suspended on the inner side of the U-shaped bracket, a folding support structure for the tarpaulin is arranged between adjacent U-shaped brackets, the folding support structure is located between the scissor-type connecting rod mechanism and the tarpaulin, and the folding support structure is used to actively separate the tarpaulin from the U-shaped bracket when the telescopic spray paint shop is folded.

[0006] By adopting the above technical solution, a retractable paint shop is provided, in which a folding support structure is arranged between adjacent U-shaped brackets. The folding support structure can automatically push the tarpaulin to a position away from the U-shaped bracket when the paint shop is retracted, which can effectively avoid damage to the tarpaulin caused by deformation of the hard structure when the paint shop is retracted.

[0007] The present invention is further configured as follows: a folding support structure is provided between the legs of two adjacent U-shaped brackets.

[0008] The present invention is further configured as follows: a folding support structure is also provided between the top connecting rods of two adjacent U-shaped brackets.

[0009] By adopting the above technical solution, the specific installation position of the folding support structure is limited, especially the arrangement of the folding support structure on the inner sides of the two legs of the U-shaped bracket, which effectively ensures the supporting effect of the tarpaulin.

[0010] The present invention is further configured as follows: the folding support structure includes a pressure rod and two rocker arm groups hinged at both ends of the pressure rod, the rocker arm group includes two rocker arms hinged at the same position of the pressure rod, the other ends of the two rocker arms are respectively hinged on two adjacent U-shaped brackets, and when the telescopic paint workshop is folded, the pressure rod can push the tarpaulin to a position away from the U-shaped bracket under the pushing action of the two rocker arms.

[0011] By adopting the above technical solution, the specific structure of the folding support structure is limited.

[0012] The present invention is further configured such that when the interval between two adjacent U-shaped brackets reaches the maximum, the two swing arms of the folding support structure are arranged in an outward-facing "X" shape with the ends hinged to each other away from the U-shaped brackets, so that the pressure rod is located on the side close to the tarpaulin.

[0013] By adopting the above technical solution, the folding support structure is set into an outward-facing figure-eight structure, which can ensure that the two swing arms of the folding support structure are folded inward when the telescopic paint shop is folded, and can further ensure the opening effect of the tarpaulin.

[0014] The present invention is further configured as follows: the swing arm is a telescopic combined rod body, the combined rod body includes a large cylinder and a small cylinder that are socketed with each other, when the telescopic paint spraying booth is folded, the large cylinder and the small cylinder slide toward each other and shorten under the action of pressure, and when the telescopic paint spraying booth is unfolded to the longest state, the large cylinder and the small cylinder slide back to back and extend under the action of external pulling force.

[0015] By adopting the above technical solution, the swing arm is designed as a retractable combined rod body, which can be retracted and retracted synchronously according to the expansion and contraction (stretching and squeezing) of the paint shop, thereby effectively preventing the folding support mechanism from causing excessive supporting force on the tarpaulin, and effectively preventing the tarpaulin from being damaged due to the support of the folding support structure.

[0016] The present invention is further configured as follows: the side walls of the large cylinder and the small cylinder are correspondingly provided with side openings; after the large cylinder and the small cylinder are sleeved, a return spring in a stretched state is connected between the fixed ends of the two; an elastic limiting structure is correspondingly provided between the sliding end of the large cylinder and the sliding end of the small cylinder, so as to achieve the limiting of the large cylinder and the small cylinder when they are stretched to the longest state.

[0017] By adopting the above technical solution, a pull-back spring is arranged between the large cylinder and the small cylinder, and a side opening is provided for facilitating the installation of the pull-back spring. At the same time, a limiting structure is provided for when the large cylinder and the small cylinder are stretched to the longest. This series of designs can automatically shorten the rocker arm under the action of the pull-back spring at the initial stage of retraction, which can more effectively avoid the contact between the folding support structure and the tarpaulin during the retraction process, and can more effectively avoid the risk of the tarpaulin being scratched.

[0018] The present invention is further configured as follows: a rubber pad with a smooth surface is arranged on the side of the pressure rod close to the tarpaulin.

[0019] By adopting the above technical solution, a rubber pad with a smooth surface is arranged on the side of the pressure rod close to the tarpaulin, which further prevents the pressure rod from scratching the tarpaulin.

[0020] The present invention is further configured as follows: a mat cloth with a smooth surface is arranged on one side of the folding support structure close to the tarpaulin.

[0021] By adopting the above technical solution, a padding cloth with a smooth surface is arranged between the folding support structure and the tarpaulin, which further avoids direct contact between the folding support structure and the tarpaulin, and more effectively avoids the tarpaulin from being scratched.

[0022] The present invention is further configured as follows: an exhaust device is provided at the fixed end of the telescopic paint spraying booth, the exhaust pipe of the exhaust device inside the telescopic paint spraying booth is foldable, and a plurality of exhaust ports are equidistantly provided on the exhaust pipe.

[0023] By adopting the above technical solution, a foldable exhaust pipe with a plurality of exhaust ports is arranged in the telescopic paint spraying workshop, which does not affect the telescopic and folding, and ensures exhaust from multiple positions, and has the advantage of good exhaust effect.

[0024] The main beneficial effects of the present invention are:

[0025] 1. The telescopic paint shop of the present invention is provided with a folding support structure between adjacent U-shaped brackets, which can automatically push the tarpaulin to a position away from the U-shaped bracket when the paint shop is folded, and can effectively avoid the damage of the tarpaulin caused by the deformation of the hard structure when the paint shop is folded.

[0026] 2. The telescopic spray booth of the present invention sets the folding support structure into an outward-facing figure eight structure, which can ensure that the two swing arms of the folding support structure fold inward when the telescopic spray booth is folded, and can further ensure the effect of opening the tarpaulin.

[0027] 3. The telescopic paint shop of the present invention designs the swing rod as an elastic telescopic rod. The elastic telescopic swing rod can effectively prevent the folding support mechanism from causing excessive supporting force on the tarpaulin, and can effectively prevent the tarpaulin from being damaged due to the support of the folding support structure.

[0028] 4. The telescopic paint shop of the present invention designs the swing arm into a telescopic combined rod body, which can be synchronously extended and retracted according to the extension and retraction (stretching and squeezing) of the paint shop, which can effectively prevent the folding support mechanism from causing excessive supporting force on the tarpaulin, and can effectively prevent the tarpaulin from being damaged due to the support of the folding support structure.

[0029] 5. The telescopic paint shop of the present invention is provided with a return spring between the large cylinder and the small cylinder, and is equipped with a side opening for facilitating the installation of the return spring. At the same time, a limiting structure is also provided when the large cylinder and the small cylinder are stretched to the longest. This series of designs can automatically shorten the rocker arm under the action of the return spring at the initial stage of retraction, which can more effectively avoid the contact between the folding support structure and the tarpaulin during the retraction process, and can more effectively avoid the risk of the tarpaulin being scratched.

[0030] 6. The telescopic spray paint shop of the present invention is provided with a smooth padding cloth between the folding support structure and the tarpaulin, which further avoids direct contact between the folding support structure and the tarpaulin, and more effectively avoids the tarpaulin from being scratched.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] like Figures 1 to 3 As shown, a telescopic spray painting workshop comprises a plurality of U-shaped brackets 2 slidably arranged on left and right side rails 1 by two legs 21, the plurality of U-shaped brackets 2 are connected by a scissor-type telescopic link mechanism 3, a tarpaulin 4 is suspended inside the U-shaped bracket 2, an exhaust device 6 is arranged at the fixed end of the telescopic spray painting workshop, a telescopic driving device is arranged at the two legs 21 of the U-shaped bracket 2 at the movable end of the telescopic spray painting workshop, and a rolling curtain retracting device 7 is arranged on the top link. When in use, the telescopic driving device can drive the workshop to telescope by operating the operating panel at the movable end.

[0039] A folding support structure 5 for the tarpaulin 4 is provided between adjacent U-shaped brackets 2 (a folding support structure 5 is provided between the legs 21 of two adjacent U-shaped brackets 2, and a folding support structure 5 is also provided between the top connecting rods 22 of two adjacent U-shaped brackets 2). The folding support structure 5 is located between the scissor-type connecting rod mechanism 3 and the tarpaulin 4. The folding support structure 5 is used to actively separate the tarpaulin 4 from the U-shaped bracket 2 when the telescopic spray painting workshop is folded. A mat with a smooth surface is provided on one side of the folding support structure 5 close to the tarpaulin 4.

[0040] The folding support structure 5 includes a pressure rod 51 and two swing rod groups hinged at both ends of the pressure rod 51. The swing rod group includes two swing rods 52 hinged at the same position of the pressure rod 51. The other ends of the two swing rods 52 are respectively hinged on two adjacent U-shaped brackets 2. When the telescopic spray paint workshop is folded, the pressure rod 51 can push the tarpaulin 4 to a position away from the U-shaped bracket 2 under the pushing action of the two swing rods 52. When the interval between the two adjacent U-shaped brackets 2 reaches the maximum, the two swing rods 52 of the folding support structure 5 are arranged in an outward eight-shaped shape in the form of the ends hinged to each other away from the U-shaped bracket 2, so that the pressure rod 51 is located on the side close to the tarpaulin 4. The side of the pressure rod 51 close to the tarpaulin 4 is provided with a rubber pad with a smooth appearance.

[0041] The swing rod 52 is a telescopic combined rod body, which includes a large cylinder 521 and a small cylinder 522 that are connected to each other. When the telescopic spray paint booth is folded, the large cylinder 521 and the small cylinder 522 slide toward each other and shorten under the action of pressure. When the telescopic spray paint booth is unfolded to the longest state, the large cylinder 521 and the small cylinder 522 slide back to back and extend under the action of external tension.

[0042] Side openings 524 are correspondingly provided on the side walls of the large cylinder 521 and the small cylinder 522. After the large cylinder 521 and the small cylinder 522 are sleeved, a return spring 523 in a stretched state is connected between the fixed ends of the two, and an elastic limiting structure 525 is correspondingly provided between the sliding end of the large cylinder 521 and the sliding end of the small cylinder 522, so as to realize the limiting of the large cylinder 521 and the small cylinder 522 when they are stretched to the longest state.

[0043] The exhaust pipe of the exhaust device 6 inside the telescopic paint spraying workshop is foldable, and a plurality of exhaust ports are equidistantly arranged on the exhaust pipe.

[0044] How it works:

[0045] The operating panel is manually operated to make the telescopic drive device slide back and forth along the track 1, thereby realizing the telescopic movement of the workshop. When the workshop retracts, the adjacent U-shaped bracket 2 axially squeezes the folding support structure 5, and the large cylinder 521 and the small cylinder 522 of the combined rod body of the folding support structure 5 first unlock the limit state, and then automatically or quickly shorten under the action of the return spring 523 to ensure that there is enough gap between the folding support structure 5 and the tarpaulin 4 during the retraction process to avoid scratching the tarpaulin 4.
