Description

Technical Field

[0001] This utility model relates to the field of windproof jacket production technology, specifically a clamping mechanism and a windproof jacket production windproof test device. Background Technology

[0002] The wind resistance testing equipment used in the production of outdoor jackets employs a precision robotic arm and specially designed clamps to easily secure jacket samples, ensuring that the samples will not fall off or shift under high-intensity wind impact. The equipment is equipped with an adjustable fan to simulate different levels of wind conditions to test the wind resistance performance of the jackets. By accurately measuring the degree of deformation of the garments under wind pressure, the equipment can provide manufacturers with accurate and repeatable test results, thereby ensuring that the jackets can provide sufficient protection in actual use.

[0003] Chinese patent CN210222017U discloses a wind resistance testing device for easy clamping in the production of rain jackets, including a shell, a through hole, and a testing mechanism. A partition is installed inside the shell. A workbench is fixed above the left side of the through hole. A fan is installed below the testing mechanism. A clamping mechanism is fixed above the workbench. The clamping mechanism includes a fixing plate, a mounting block, a return spring, a clamping plate, and a rubber pad. The mounting block is fixed to the left side of the fixing plate, and a return spring is connected to the bottom of the fixing plate. A clamping plate is installed below the return spring, and a rubber pad is attached to the bottom surface of the clamping plate. A side plate is fixed to the left side of the clamping mechanism.

[0004] However, the above solution only uses the friction of the clamps and rubber pads to hold the jacket in place. Under strong winds, the jacket fabric may be blown off, and the jacket fabric cannot be held in place securely. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a clamping mechanism, comprising: two fixing plates 1, each fixing plate 1 having fixing holes 2 at all four ends, the fixing plates 1 being placed on the mounting platform plates on the left and right sides of the air outlet of the wind resistance testing equipment for producing windproof jackets, and fixed with bolts, each fixing plate 1 having a rotating roller 4 rotatably connected to its upper end, and side plates 3 being fixedly installed on the front and rear sides of the upper end of the fixing plates 1, the front and rear ends of the rotating roller 4 being rotatably connected to the two side plates 3 through bearings, and a motor 5 being fixedly installed on the outer end of one of the side plates 3, the output shaft of the motor 5 being fixedly connected to one end of the rotating roller 4, the motor 5 driving the rotating roller 4 to rotate when started.

[0019] A clamping groove 10 is provided on the outer wall of the rotating roller 4. An arc-shaped plate 11 is provided on the outer side of the clamping groove 10. One end of the arc-shaped plate 11 is rotatably connected to the rotating roller 4. A rotating plate 21 is fixedly installed on one end of the rotating roller 4. A rotating block 22 is fixedly installed on one end of the arc-shaped plate 11. The rotating block 22 is rotatably connected to the rotating plate 21 through a rotating shaft. A rubber strip 12 is fixedly installed on the inner end of the arc-shaped plate 11. The fabric of the rain jacket to be tested is placed on the outer end of the rotating roller and located at the upper end of the clamping groove 10. Then, the arc-shaped plate 11 is rotated so that it fits against the outer end of the rotating roller 4. The rubber strip 12 inserts into the clamping groove 10 by squeezing itself, thereby firmly clamping the fabric of the rain jacket.

[0020] The other end of the arc-shaped plate 11 is fixedly connected to the rotating roller 4 via a connecting component. The connecting component includes a fixing block 14 and a support plate 16. The fixing block 14 is fixed to the other end of the arc-shaped plate 11, and the support plate 16 is fixed to the other end of the rotating roller 4. A limit block 15 is fixedly installed on the outer end of the fixing block 14, and a limit block 27 is slidably inserted into the upper end of the support plate 16. A push plate 18 is fixedly installed on the upper side of one end of the limit block 27, and ear plates 19 are fixedly installed on both the left and right sides of one end of the limit block 27. A spring 20 is fixedly installed on one side of the ear plate 19. The other end is fixedly connected to the support plate 16. The second limiting block 17 can slide on the upper end of the support plate 16 through the tension spring 20. The outer end of the arc plate 11 is fixedly installed with a handle 13. When the arc plate 11 is attached to the surface of the rotating roller 4, the slope at the lower end of the first limiting block 15 contacts the slope at the upper end of the second limiting block 17, thereby pushing the second limiting block 17 outward. The first limiting block 15 passes over the second limiting block 17, thereby fixing the arc plate 11 on the surface of the rotating roller 4 and restricting the rubber strip 12 in the clamping groove 10, thereby firmly fixing the jacket fabric.

[0021] A driving component is provided between the two rotating rollers 4. The driving component includes a gear 6, a rotating shaft 7, a sprocket 8, and a chain 9. The rotating shaft 7 is rotatably mounted on the outer end of one of the side plates 3. The gear 6 and the sprocket 8 are fixedly mounted on the outer end of the rotating shaft 7. The gear 6 is fixedly mounted on one end of one rotating roller 4, and the sprocket 8 is fixedly mounted on one end of the other rotating roller 4. The outer walls of the two gears 6 are meshed with each other. The chain 9 is connected to the outer ends of the two sprockets 8. When the motor 5 drives one rotating roller 4 to rotate, the rotating shaft 7 drives the sprocket 8 to rotate under the action of the gear 6. The sprocket 8 drives the chain 9 to drive the other rotating roller 4 to rotate, so that the two rotating rollers 4 can rotate outward synchronously.

[0022] A wind resistance testing device for outdoor jackets includes the aforementioned clamping mechanism.

[0023] In actual use, the two ends of the fabric of the jacket that needs to be tested for wind resistance are respectively attached to the outer walls of the two rotating rollers 4 and fixed by the arc plate 11 and rubber strip 12. At this time, the middle part of the fabric is concave downward. Then, the motor 5 is started to drive the two rotating rollers 4 to rotate outward at the same time, and the fabric is rolled up around the outer end of the rotating rollers 4. At this time, the fabric is in a slightly loose or slightly taut state. At the same time, the fabric is firmly clamped, and the wind resistance testing equipment can be started to test the wind resistance of the fabric.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
