Description

Technical Field

[0001] The utility model belongs to the technical field of tourism production equipment, and in particular relates to a tent zipper arch stretching device. Background Art

[0002] The zipper on a tent is a crucial component, allowing users to easily open and close the tent entrance. However, since tent doors and windows are mostly curved, and zippers are generally straight, a straight zipper built directly onto these curved doors and windows would create a wavy, three-dimensional appearance. To ensure the finished tent's aesthetics and the smoothness of the zippers on these curved doors and windows, the arch of the zipper needs to be stretched.

[0003] Currently, zippers are often stretched and extended using a laminating machine combined with manual stretching. The laminating machine's rubber rollers work in conjunction with a heating system to heat the zipper, which is then stretched manually. However, this method can cause problems such as excessive stretching and scorching of the zipper, as the manual pulling force cannot be consistent every time, rendering the zipper useless.

[0041] like Figure 1 As shown, the present invention provides a tent zipper arch stretching device, which includes: a frame 1 and two stretching devices 3. The frame 1 has two tables 2 spaced apart along a first direction. As can be seen from the figure, the first direction is the horizontal direction along the length of the frame 1. The two stretching devices 3 are respectively located on the two spaced apart tables 2, forming two stretching devices 3 symmetrically arranged on the frame 1 along the first direction.

[0042] The stretching device 3 includes a sliding seat 301 , a first driving cylinder 303 and a second driving cylinder 304 .

[0043] The sliding seat 301 is slidably arranged on the frame 1. The sliding seat 301 includes a base and four rollers connected to the bottom of the base. The base can be formed by a flat plate and moves on the table 2 of the frame 1 through the four rollers. The sliding seat 301 is provided with a first clamping portion 302 extending outward near the other stretching device 3. Since the two stretching devices 3 are arranged at intervals, the first clamping portion 302 extends inwardly through an extension rod 14, so that the first clamping portions 302 in the stretching devices 3 on both sides extend inwardly, which is convenient for personnel to operate;

[0044] The first driving cylinder 303 is also arranged along the first direction, and the output end of the first driving cylinder 303 is connected to the sliding seat 301, so that the first driving cylinder 303 drives the sliding seat 301 to move back and forth along the first direction when it is extended and retracted. The second driving cylinder 304 is installed in the sliding seat 301, and the output end of the second driving cylinder 304 is installed with a second clamping part 305. The second driving cylinder 304 pushes the second clamping part 305 to contact the first clamping part 302 for clamping the zipper. The driving force of the second driving cylinder 304 pushes the second clamping part 305 to contact the first clamping part 302, so as to tightly clamp and fix the zipper, providing a basis for maintaining consistency in the length of subsequent stretching.

[0045] The driving device 4 is arranged on the frame 1, and is located between the two stretching devices 3, specifically at the bottom of the frame 1, which is convenient for stepping on. The driving device 4 is connected to the external power source and is connected to the first driving cylinder 303 and the second driving cylinder 304. The driving device 4 controls the on and off of the power source of each driving cylinder. In this embodiment, the driving cylinder can be implemented by a pneumatic driving cylinder or an electric push rod, etc., and the action is fast and accurate. The driving device 4 is used as a switch between the power source and the driving cylinder.

[0046] The driving device 4 controls the second driving cylinder 304 to push the second clamping part 305 forward and abut against the first clamping part 302 at the front end, thereby clamping one end of the zipper. The two stretching devices 3 symmetrically arranged at intervals can respectively clamp the two ends of the zipper. Then, the driving device 4 controls the two first driving cylinders 303 to push the sliding seat 301 outward, thereby pushing the two second driving cylinders 304 clamping the two ends of the zipper outward to stretch the zipper. By clamping and stretching through the driving cylinders, the stretching length can be controlled and the problem of being scorched by the heating device can be avoided.

[0047] Specifically, taking the power source as the air source and the driving cylinder as the air cylinder as an example, the driving device 4 includes a first foot valve 401 and two second foot valves 402. The first foot valve 401 is connected to the two first driving cylinders 303, and the two second foot valves 402 are respectively connected to the two second driving cylinders 304. The foot valve controls the on-off of the air circuit to realize the action control of the driving cylinder. In this embodiment, the air circuit pipe connecting the driving cylinder and the foot valve is not shown.

[0048] In this embodiment, in order to avoid damaging the zipper, the first clamping portion 302 and the second clamping portion 305 are covered with a cushioning rubber head 8 . The cushioning rubber head 8 can be made of a softer material such as plastic.

[0049] In order to keep the moving direction of the sliding seat 301 controllable and the telescopic length controllable, the table 2 of the frame 1 below the sliding seat 301 is provided with a limit slot 5 along the first direction, and a limit link 6 is matched in the limit slot 5. The width of the limit link 6 is consistent with the limit slot 5. The limit link 6 can reciprocate along its length direction in the limit slot 5. The two ends of the limit link 6 are fixedly connected to the sliding seat 301 and the output end of the first drive cylinder 303 respectively. Specifically, the sliding seat 30 1 is located above the table 2 of the frame 1, and the first driving cylinder 303 is fixed to the bottom of the table 2 of the frame 1 and is fixedly connected by a limit link 6, driving the sliding seat 301 to move back and forth. When the first driving cylinder 303 extends, causing the limit link 6 at its output end to reach the end of the limit slot 5, the limit link 6 limits the extension of the first driving cylinder 303, thereby controlling the extension length of the first driving cylinder 303, and further controlling the stretching length of the zipper, thereby ensuring the consistency of product batches.

[0050] like Figure 2 As shown, in order to improve the applicability of the device, an adjusting device 7 is further included for controlling the telescopic length of the first driving cylinder 303 , which includes: an adjusting rod 701 and an adjusting plate 702 .

[0051] The adjusting rod 701 is fixed on the frame 1 along the first direction, and the adjusting plate 702 is slidably sleeved on the adjusting rod 701 and can move on the adjusting rod 701 along the first direction. The adjusting plate 702 is fixed to the adjusting rod 701 by a fastener, and can also be fastened to a certain position on the adjusting rod 701. The first driving cylinder 303 is fixedly installed on the adjusting plate 702. By changing the position of the adjusting plate 702 on the adjusting rod 701, the position of the first driving cylinder 303 is changed, and the limiting groove 5 is cooperated to adjust the spacing between the two stretching devices 3. If the zipper length is required to be shorter and the two stretching devices 3 are far apart, the positions of the adjusting plates 702 in the two stretching devices 3 can be adjusted closer to reduce the spacing between the two stretching devices 3, and the stretching length of the zipper can be adjusted at the same time.

[0052] Specifically, two adjusting rods 701 are provided, which are respectively provided on both sides of the first driving cylinder 303 . The two adjusting rods 701 can ensure the stability of the fixation of the first driving cylinder 303 .

[0053] Among them, the adjusting rod 701 is a threaded adjusting rod 701, and the fastener includes two fastening nuts 703 threadedly connected to the threaded adjusting rod 701. The two fastening nuts 703 are clamped and fixed on both sides of the adjusting plate 702. When adjustment is required, the fastening nuts 703 are loosened. After the position of the adjusting plate 702 is adjusted into place, the fastening nuts 703 on both sides are tightened.

[0054] In order to further improve the control of the stretching length of the zipper, a slide groove 9 is provided on the sliding seat 301 along the first direction, and a slide plate 10 is provided in the slide groove 9. The slide groove 9 is used to limit the reciprocating movement of the slide plate 10 along the first direction, and a limit frame 11 is provided on the slide plate 10 for fixing the second driving cylinder 304.

[0055] At the same time, the first clamping portion 302 is connected to the limit frame 11 through the extension rod 14. The first clamping portion 302 can be adjusted as the slide plate 10 moves back and forth in the first direction, thereby further adjusting the distance between the two stretching devices 3 and adjusting the length of the zipper rope.

[0056] Since the second driving cylinder 304 is fixed on the slide 10 through the limiting block, the position of the second driving cylinder 304 can be adjusted by sliding the slide 10 connected in the sliding groove 9.

[0057] When the skateboard 10 is fixed in the slide groove 9, it is achieved through the limit handle 12. The limit handle 12 passes through the skateboard 10 and the strip groove 13 opened at the bottom of the slide groove 9 in sequence and is tightened and fixed to fasten the skateboard 10 in the slide groove 9. Specifically, the strip groove 13 opened at the bottom of the slide groove 9 facilitates the passage of the limit handle 12 after passing through the skateboard 10. After the bottom of the limit handle 12 passes through the strip groove 13 of the skateboard 10, it can be tightened and fixed by fasteners to clamp the skateboard 10 in the slide groove 9 to achieve position fixing. At the same time, the limit handle 12 can also be used as a handle temporarily.

[0058] In specific use, after the positions of the skateboard 10 together with the second driving cylinder 304 and the first driving cylinder 303 thereon are fixed, the operation is realized by stepping on the foot valves in the driving device 4. First, the second foot valve 402 can be a normally closed type, that is, when the foot is stepped on, the second driving cylinder 304 retracts, separating the second clamping part 305 from the first clamping part 302. At this time, the zipper is inserted. The two second foot valves 402 control the two second driving cylinders 304 to retract and then insert them into the two ends of the zipper respectively. Then, the second foot valves 402 are released. At this time, the second driving cylinders 304 extend, pushing the second clamping part 305 forward to contact the first clamping part 302 to clamp the two ends of the zipper.

[0059] Then, the first foot valve 401 is stepped on. The first foot valve 401 can be normally open, that is, after the foot is stepped on, the first drive cylinder 303 is activated to push the sliding seat 301 to both sides. Since the second drive cylinder 304 remains in an extended state at this time, tightly clamping the two ends of the zipper, the extension of the first drive cylinder 303 can achieve the effect of stretching the zipper. Then, the first foot valve 401 is released, the first drive cylinder 303 retracts, and then the second foot valve is stepped on to make the two second drive cylinders 304 retract, loosening the two ends of the zipper, and the stretched zipper can be taken out.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
