Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a fastening clamp for detecting the tension of cloth socks. Background Technology

[0002] In the textile industry, quality inspection of cloth socks is a crucial step in ensuring product quality, and tension testing is one of the important testing items. Currently, the common method for testing the tension of cloth socks is to use a tensile testing machine to stretch the socks and measure the tensile force generated during the stretching process, thereby evaluating their tensile performance.

[0003] In existing stocking tension testing devices, the stockings are typically secured using traditional bolt fastening. This method requires operators to rotate multiple bolts to push the clamping plate closer to and against the stocking, and then gradually tighten the bolts to achieve clamping. However, this traditional fastening method has many drawbacks: First, the bolts need to travel a long distance to bring the clamping plate closer, against, and tighten it, resulting in numerous steps and a long processing time, which seriously affects testing efficiency. Second, to ensure the clamping effect, the bolts often need to be over-tightened, which makes it extremely inconvenient to disassemble the stocking after testing, further reducing the overall testing efficiency.

[0004] A fastening clip for detecting the tension of cloth stockings is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a fastening clamp for testing the tension of cloth socks, so as to solve the many drawbacks of the traditional fastening methods mentioned in the background art: First, the bolt needs to go through a long distance to achieve the approach, contact and fastening of the clamping plate, which involves many operation steps and is time-consuming, seriously affecting the testing efficiency. Second, in order to ensure the clamping effect, the bolt often needs to be over-tightened, which makes it extremely inconvenient to disassemble the cloth sock after the test, further reducing the overall testing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fastening clamp for detecting the tension of cloth socks, comprising a tensile testing machine base, wherein a control device and a pulling device are fixedly installed on the top of the tensile testing machine base, and the pulling device includes a tensile sensor;

[0007] Below the tension sensor are a pair of vertically distributed fastening components. The fastening components include a jacket, with side plates symmetrically fixed to one side of the jacket. A compression block is located between the two side plates, and a pressure plate is fixedly connected to the outside of the compression block. A movable rod is slidably connected to one side of the jacket. A compression plate is fixedly connected to one end of the movable rod, and a hollow curved block is slidably connected to the other end of the movable rod. A threaded sleeve is fixedly embedded on the other side of the jacket. A threaded post is threadedly connected to the middle of the threaded sleeve. A knob is fixedly connected to one end of the threaded post, and a force-bearing pad is rotatably connected to the other end of the threaded post. A clearance groove is provided on the inner wall of the jacket.

[0008] Preferably, the two sides of the extrusion block are symmetrically fixedly connected to side shafts, and friction rings are fixedly connected to the outside of the side shafts.

[0009] Preferably, the side shaft is eccentrically connected to the extrusion block, the friction ring is in contact with the inner wall of the side plate, and the side shaft is rotatably connected to the inner wall of the side plate.

[0010] Preferably, the force-bearing pad is embedded in the clearance groove, one sleeve is fixedly connected to the sensing end of the tension sensor, and the other sleeve is fixedly connected to the top surface of the tension testing machine base.

[0011] Preferably, the extrusion plate and the force-bearing pad are at the same height, and the hollow curved block is located outside the jacket and is in contact with the outer side of the extrusion block.

[0012] Preferably, a pre-clamping assembly is provided at the top of the upper sleeve. The pre-clamping assembly includes a suspension rod fixed to the top of the sleeve. A spring and a movable block are sleeved on the outside of the suspension rod. A curved plate is fixedly connected to the bottom of the spring, and a rubber wheel is rotatably connected to the bottom end of the curved plate.

[0013] Preferably, the movable block is slidably connected to the spring, one end of the spring is fixedly connected to the movable block, and the other end of the spring is fixedly connected to the inner wall of the jacket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This fastening clamp for testing the tension of cloth socks, through a graded clamping design combining eccentric extrusion and threaded fine adjustment, not only eliminates the tedious operation of long-distance bolt movement, but also adapts to socks of different thicknesses and avoids disassembly difficulties, thus improving testing efficiency and convenience. The specific details are as follows:

[0015] 1. During operation, the hand-held pressure plate is shaken to rotate the extrusion block. Its eccentric design with the side shaft extrudes the hollow curved block, which in turn moves the movable rod and the extrusion plate, initially clamping the sock in conjunction with the force-bearing pad. This design avoids relying solely on bolts to push the clamping plate a long distance to achieve proximity, fit, and tightening, significantly saving operation time. Afterwards, rotating the knob slightly moves the threaded post within the threaded sleeve, fine-tuning the position of the force-bearing pad and increasing the clamping force. This tiered clamping method ensures effective clamping of socks of different thicknesses while avoiding over-tightening the bolts to guarantee clamping effectiveness, which would lead to extremely inconvenient subsequent disassembly, thus improving the efficiency and convenience of the entire inspection process.

[0016] 2. When testing the tension of cloth socks, the pre-clamping assembly is first used to pre-clamp the top of the sock. The top of the sock is pushed upwards and pressed against the rubber wheel. The rolling of the rubber wheel and the sliding of the movable block on the suspension bar allow the sock to smoothly enter the pre-clamping position. The spring pushes the movable block to clamp the top of the sock with the rubber wheel, keeping the sock suspended. This avoids the need for one hand to hold the sock constantly when it is vertically clamped, making it more convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a fastening clamp for detecting the tension of cloth socks, including a tension testing machine base 1. A control device 101 and a pulling device 102 are fixedly installed on the top of the tension testing machine base 1. The pulling device 102 includes a tension sensor 103. The pulling device 102 includes a motor, a screw transmission device, and a tension sensor 103. The motor drives the components connected to the cloth sock to move through the screw transmission device. The tension sensor 103 is used to detect the tension generated during the movement. After the two ends of the cloth sock are clamped by the fastening assembly 2, the tension sensor 103 will move vertically under the drive of the transmission device to pull the cloth sock, making the cloth sock longer, and detecting its tension.

[0024] Below the tension sensor 103, there is a pair of vertically distributed fastening components 2. The fastening components 2 include a sleeve 201. Side plates 202 are symmetrically fixedly connected to the outside of one side of the sleeve 201. A compression block 203 is provided between the two side plates 202. A pressure plate 204 is fixedly connected to the outside of the compression block 203. A movable rod 205 is slidably connected through one side of the sleeve 201. One end of the movable rod 205 is fixedly connected to a compression plate 207, and the other end of the movable rod 205 is slidably connected to a hollow curved block 206. A threaded sleeve 208 is fixedly embedded on the other side of the sleeve 201. A threaded post 209 is threadedly connected to the middle of the threaded sleeve 208. A knob 210 is fixedly connected to one end of the threaded post 209, and a force-bearing pad 211 is rotatably connected to the other end of the threaded post 209. A clearance groove 212 is provided on the inner wall of the sleeve 201. By holding the pressure plate 204 and shaking it, the pressure plate 204 moves and fits against the outer side of the sleeve 201. At this time, the extrusion block 203 is in a dead point of rotation and will not be affected by the hollow curved block 206. Under the action of force, the extrusion block 203 rotates in the opposite direction, rotating around the side shaft 2031. The eccentric design of the extrusion block 203 and the side shaft 2031 causes the extrusion block 203 to extrude force on the hollow curved block 206, thereby causing the movable rod 205 to slide and drive the extrusion plate 207 to move a fixed distance. In conjunction with the force-bearing pad 211 located in the relief groove 212, the sock is clamped. Finally, by holding the knob 210 and trying to rotate it, the threaded column 209 engages with the threaded sleeve 208. The downward slight movement ultimately causes the force-bearing pad 211 to be slightly adjusted in position within the clearance groove 212, increasing the clamping force between the force-bearing pad 211 and the clearance groove 212, thus increasing the stability of the sock after clamping. This avoids the limitation of the moving distance of the movable rod 205, which would prevent it from being unable to clamp socks of different thicknesses. This device avoids the long-distance movement required by bolts when clamping, where the bolts need to push the clamping plate closer, fit, and then tighten, saving time. It also avoids the situation where bolts need to be tightened to ensure clamping, which would make disassembly extremely inconvenient.

[0025] The two sides of the extrusion block 203 are symmetrically fixedly connected to the side shafts 2031, and the friction rings 2032 are fixedly connected to the outside of the side shafts 2031.

[0026] The side shaft 2031 is eccentrically connected to the extrusion block 203, the friction ring 2032 is in contact with the inner wall of the side plate 202, and the side shaft 2031 is rotatably connected to the inner wall of the side plate 202; the friction ring 2032 can keep the extrusion block 203 at any angle when idle, and prevent it from swaying.

[0027] The force-bearing pad 211 is embedded in the clearance groove 212. One sleeve 201 is fixedly connected to the sensing end of the tension sensor 103, and the other sleeve 201 is fixedly connected to the top surface of the tension testing machine base 1. When the tension sensor 103 is raised or lowered, it can sense the pulling force of the fastening component 2 on it, and transmit the data to the control device 101 through electrical connection.

[0028] The extrusion plate 207 and the force-bearing pad 211 are at the same height. The hollow curved block 206 is located outside the jacket 201 and is in contact with the outer side of the extrusion round block 203. When the extrusion round block 203 rotates, the contact surface between the hollow curved block 206 and the extrusion round block 203 will cause the hollow curved block 206 to undergo adaptive sliding and avoidance.

[0029] A pre-clamping assembly 3 is provided at the top of the inner sleeve 201. The pre-clamping assembly 3 includes a suspension rod 301 fixed to the top of the inner sleeve 201. A spring 302 and a movable block 303 are sleeved on the outside of the suspension rod 301. A curved plate 304 is fixedly connected to the bottom of the spring 302. A rubber wheel 305 is rotatably connected to the bottom end of the curved plate 304. First, the top of the sock is pushed up against the inner wall of the suspension rod 301 to squeeze against the rubber wheel 305. While the rubber wheel 305 is rolling, the movable block 303 slides on the suspension rod 301, so that the rubber wheel 305 avoids the sock. Then, the spring 302 pushes the movable block 303 to make the rubber wheel 305 clamp the top of the sock, so that the sock is kept in a suspended state when it is fixed later, which facilitates its subsequent tightening.

[0030] The movable block 303 is slidably connected to the spring 302. One end of the spring 302 is fixedly connected to the movable block 303, and the other end of the spring 302 is fixedly connected to the inner wall of the clip 201. The spring 302 can reset the movable block 303, realizing the pre-clamping of the sock by the rubber wheel 305, avoiding the need for one hand to hold the soft sock at all times when it is clamped vertically, which is more convenient.

[0031] Working principle: Before using this type of hosiery tension testing clamp, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 4 As shown, when performing tension testing on the socks, the top of the sock is first pre-clamped using the pre-clamping assembly 3. The top of the sock is pushed upward against the inner wall of the suspension rod 301, pressing against the rubber wheel 305. The rubber wheel 305 rolls, and the movable block 303 slides on the suspension rod 301 to avoid being in a position. The spring 302 pushes the movable block 303 to make the rubber wheel 305 clamp the top of the sock, keeping the sock in a suspended state.

[0032] Next, fastening assembly 2 is used to secure both ends of the sock. Holding pressure plate 204 and shaking it, the squeezing block 203 rotates around the side shaft 2031. Its eccentric design causes it to squeeze the hollow curved block 206, driving the movable rod 205 to slide. The squeezing plate 207 moves a certain distance, initially clamping the sock in conjunction with the force-bearing pad 211. Then, the knob 210 is rotated by hand, the threaded column 209 moves slightly in the threaded sleeve 208, and the force-bearing pad 211 is finely adjusted in the position of the relief groove 212 to increase the clamping force and ensure that socks of different thicknesses can be clamped.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
