Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a portable fabric tearing strength tester. Background Art

[0002] Most of the existing fabric materials need to be subjected to anti-tearing detection, mainly to prevent the upper or lower garments from being torn during wearing. For example, when wearing trousers and squatting or stretching, the crotch, waist darts, belt loops, pockets of the trousers, etc. may be torn. When wearing trousers and performing actions such as squatting, stretching or pulling the pockets with hands, it is easy to tear the fabric; also, for the upper garment at the armpit, back, etc., when performing some large-scale movements, tearing or splitting is likely to occur. Therefore, when the existing R & D personnel prepare ready-to-wear clothes and trousers, they first conduct a tearing test on the fabric. If the fabric does not tear when the pulling force is greater than the artificially set value, it is determined as a qualified fabric.

[0003] At present, there are already devices for tearing tests on the market, which can accurately test the change in the force applied during the tearing process by clamping the fabric piece. However, the existing devices also have certain limitations, specifically as follows: (1) They are expensive. It is difficult for small companies that do not manufacture clothing to bear this cost, and it is difficult for some small fabric stores (trading companies) to purchase them for testing; (2) They are too large and heavy in volume, occupying a large space and requiring professional personnel for fine operation; (3) They have poor portability. Therefore, how to design a detection device with low cost, small volume and low selling price is an urgent problem for industry personnel to consider. Content of the Utility Model

[0004] The utility model provides a portable fabric tearing strength tester, which has a simple structure, is convenient to manufacture with low cost, has strong convenience, and solves the problems of the existing tearing test devices being too expensive, too large in volume, occupying a large space and having complex operation. The main technical scheme is as follows:

[0005] A portable fabric tearing strength tester is used for the anti-tearing detection of fabrics; it is characterized in that: it includes: a base, which is provided with a supporting platform and a control console located above the supporting platform; a fabric clamping mechanism, which includes a first clamping member and a second clamping member for clamping both ends of the fabric. The first clamping member and the second clamping member respectively form a first clamping end and a second clamping end when clamping both ends of the fabric; the first clamping member is slidably arranged on the control console and is fixedly connected to a guiding mechanism inside the control console; a gravity block is installed on the second clamping member, and both the gravity block and the second clamping member are supported on the guiding mechanism on the surface of the supporting platform. The guiding mechanism drives the first clamping member to slide on the control console, and through the fabric, the second clamping member and the gravity block are suspended at a certain height relative to the supporting platform, so that the second clamping end moves away from the first clamping end under the action of the gravity of the gravity block to complete the tearing of the fabric.

[0006] Preferably, the guiding mechanism comprises a turning handle inserted on the control console, and a swing rod and a fixed block hinged to each other inside the control console; one end of the swing rod is clamped on the first clamping member, and the other end is abutted against the turning handle; rotating the turning handle drives the swing rod to rotate on the fixed block, thereby linking the first clamping member to slide on the control console.

[0007] Preferably, the throttle is convexly provided with a guide portion, and when the throttle is inserted on the console, the guide portion is located on the upper side of the rocker arm; when the throttle is rotated, the guide portion presses one end of the rocker arm downward and drives it to rotate on the fixed block, so that the other end of the rocker arm tilts upward, linking the first clamping member to slide on the console.

[0008] Preferably, the first clamping member is rod-shaped, and a limiting portion is convexly provided on its outer peripheral surface. When the first clamping member is slidably mounted on the console, the limiting portion is engaged with the console to constrain the first clamping member on the console to limit the rotation angle of the rocker arm relative to the fixed block.

[0009] Preferably, the first clamping member has a clearance space for accommodating the rocker arm; the first clamping member is provided with a latch pin penetrating the clearance space, and when the rocker arm is arranged in the clearance space, the latch pin cooperates with the first clamping member to clamp and constrain the rocker arm.

[0010] Preferably, the first clamping member and the second clamping member have a clamping mechanism; the clamping mechanism comprises a first clamping claw and a second clamping claw, and the first clamping claw and the second clamping claw can clamp the fabric by fitting together.

[0011] Preferably, the first clamping claw and the second clamping claw are respectively provided with a tightening hole, and the two tightening holes are simultaneously locked with an adjusting structure; the tightening structure includes a tightening bolt passing through the two tightening holes, and a tightening nut threadedly connected to the tightening bolt, and by locking the tightening bolt and the tightening nut, the first clamping claw and the second clamping claw are driven to fit together to clamp the fabric.

[0012] Preferably, the second clamping claw is provided with a mounting body for mounting a gravity block.

[0013] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The technical solution of the utility model provides a portable fabric tearing strength tester, which has a simple structure, is easy to manufacture, has low cost, and is highly convenient. It also solves the problems of existing tearing test equipment being too expensive, too large in size, occupies a large space, and is complicated to operate. The specific solution is that the two ends of the fabric are clamped by a first clamp and a second clamp, and a gravity block (weight) with a predicted weight is installed on the second clamp; in actual implementation, the fabric, the second clamp, and the gravity block are suspended in the air by the first clamp to test whether the fabric will tear under the influence of the gravity of the gravity block. If the fabric tears under the influence of the gravity block, it can be determined that the fabric's tear resistance and tensile strength are insufficient; the solution has a simple structure, and can be manufactured and assembled using a simple process and simple parts as a whole. The manufacturing difficulty is extremely low, which can save manufacturing costs, making the equipment more cost-effective and beneficial, so that small cloth shops and companies can benefit.

[0015] (2) In the present technical solution, fabric refers to cloth or cloth pieces; before being torn, it needs to be supported to ensure that the gravity block is placed stably; if the gravity block is installed on the second clamping member, the gravity block and the second clamping member are in a suspended state, and the second clamping member will begin to shake under the action of the gravity block. The force generated during the shaking process may make the fabric more likely to be torn, affecting the detection results. Therefore, the method of first stably supporting and then detecting can ensure the accuracy of the detection data and reduce the occurrence of errors.

[0016] (3) In the present technical solution, the handle is used to drive the rocker arm to rotate on the fixed block, thereby linking the first clamping member to slide, thereby achieving the purpose of saving effort. The structural composition is intuitive, the structure is simple, and the manufacturing and assembly are convenient.

[0017] (4) A limit portion is provided on the first clamping member to constrain the first clamping member on the control console, so as to ensure that each time the gravity block is placed on the second clamping member, the height of the gravity block and the second clamping member can be exactly matched with the height of the supporting platform, thereby ensuring that the gravity block can be placed stably and the accuracy of the detection data can be guaranteed.

[0028] Please refer to Figures 1 to 3 。

[0029] This embodiment provides a portable tearing strength tester for fabric A, which is used for anti-tearing detection of fabric A. It has a simple structure, is easy to manufacture with low cost, has strong convenience, and solves the problems of existing tearing test equipment being too expensive, too large in size, occupying a large space, and having complex operation. It mainly includes a base 1, a material clamping mechanism 2, and a guiding mechanism 3; among which:

[0030] The base 1 is provided with a supporting platform 11, and a control console 12 is supported on the base 1 through a supporting plate. The control console 12 is located above the supporting platform 11;

[0031] The material clamping mechanism 2 includes a first clamping member 21 and a second clamping member 22 for clamping both ends of fabric A. The first clamping member 21 is located above the second clamping member 22. The first clamping member 21 and the second clamping member 22 form a first clamping end and a second clamping end respectively when clamping both ends of fabric A; the first clamping member 21 is slidably arranged on the control console 12 and is fixedly connected to the guiding mechanism 3 inside the control console 12; a gravity block B is installed on the second clamping member 22, and both the gravity block B and the second clamping member 22 are supported on the tabletop of the supporting platform 11;

[0032] In this embodiment, fabric A is a cloth or a cloth piece; for the convenience of detection, fabric A is torn by at least one-third so that fabric A is bifurcated into two pieces, and the two pieces are respectively clamped by the first clamping member 21 and the second clamping member 22;

[0033] In this embodiment, the first clamping member 21 is rod-shaped, and a limiting portion 211 is convexly provided on its outer peripheral surface. The limiting portion 211 is annular. When the first clamping member 21 is slidably arranged on the control console 12, the limiting portion 211 is clamped on the control console 12 to restrict the first clamping member 21 so that it maintains a certain suspended height and can never completely pass through the control console 12;

[0034] In this embodiment, the upper end of the first clamping member 21 is clamped by the guiding mechanism 3, and a clamping mechanism is provided at the lower end. The first clamping member 21 clamps one end of fabric A through the clamping mechanism; the second clamping member 22 is rod-shaped, and a clamping mechanism is provided at its upper end. The second clamping member 22 clamps the other end of fabric A through the clamping mechanism. A carrier 221 for installing the gravity block B is connected to the lower end of the second clamping member 22, and the gravity block B is a weight with a self-selected gravity.

[0035] In this embodiment, the carrier 221 is in the shape of a hook, and when the weight block B is placed on the carrier 221, the carrier 221 can be limited by the hook structure. In other embodiments, the carrier 221 can also be in the shape of a disc or a square.

[0036] In this embodiment, when the limit portion 211 is clamped on the control console 12 to constrain the first clamping member 21, it can be ensured that each time the gravity block B is placed on the second clamping member 22, the height of the gravity block B and the second clamping member 22 can just match the height of the supporting platform 11, ensuring that the gravity block B can be stably placed on the surface of the supporting platform 11, so that the second clamping member 22 will not shake under the action of the gravity block B.

[0037] The guiding mechanism 3 includes a turning handle 31 inserted on the control console 12, and a swing rod 32 and a fixed block 33 which are hinged to each other and are arranged in the control console 12; wherein, one end of the swing rod 32 is clamped and fixed to the first clamping member 21, and the other end is against the turning handle 31; rotating the turning handle 31 drives the swing rod 32 to rotate on the fixed block 33, and drives the first clamping member 21 to slide on the control console 12 in linkage, so as to drive the second clamping member 22 and the gravity block B to be suspended at a certain height relative to the supporting platform 11 through the fabric A, so that the second clamping end moves away from the first clamping end under the gravity of the gravity block B, so as to complete the tearing of the fabric A.

[0038] In this embodiment, a guiding portion 311 is protruded on the turning handle 31. When the turning handle 31 is inserted into the control console 12, the guiding portion 311 is just located on the upper side of the swing rod 32. When the turning handle 31 is rotated, the guiding portion 311 presses one end of the swing rod 32 downward and drives it to rotate on the fixing block 33, so that the other end of the swing rod 32 is tilted upward. Through the lever principle, the first clamping member 21 is linked to slide on the control console 12.

[0039] In this embodiment, the first clamping member 21 has a clearance space 21A for accommodating the rocker arm 32; the first clamping member 21 is provided with a latch 212 that passes through the clearance space 21A. When the rocker arm 32 is arranged in the clearance space 21A, the latch 212 cooperates with the first clamping member 21 to clamp and restrain the rocker arm 32, that is, the latch 212 will directly abut and rub against the rocker arm 32 to limit and fix it.

[0040] In this embodiment, the first clamping member 21 and the second clamping member 22 have a clamping mechanism; the clamping mechanism includes a first clamping claw 41 and a second clamping claw 42, and the first clamping claw 41 and the second clamping claw 42 are symmetrically arranged; the first clamping claw 41 and the second clamping claw 42 are respectively provided with a tightening hole, and the two tightening holes are symmetrically arranged and locked with the tightening structure at the same time.

[0041] In this embodiment, the tightening structure includes a tightening bolt (not shown in the figure) passing through two tightening holes and a tightening nut (not shown in the figure) screwed onto the tightening bolt. By tightening the tightening bolt and the tightening nut, the first clamping jaw 41 and the second clamping jaw 42 are driven to fit together, so that the first clamping member 21 and the second clamping member 22 can clamp the fabric A. When it is necessary to remove the fabric A, only the adjusting bolt needs to be rotated again.

[0042] The working principle and usage process of the present utility model:

[0043] Before the detection, first determine the gravity to be measured to select the gravity block B (weight), and at the same time bifurcate and tear the fabric A into two parts;

[0044] When starting the detection, referring to Figure 2, first, the two bifurcated parts of the fabric A are respectively clamped by the first clamping member 21 and the second clamping member 22. Then, the gravity block B is installed on the carrier 221 at the lower end of the second clamping member 22, and both the gravity block B and the second clamping member 22 are supported on the tabletop of the support table 11. Next, referring to Figure 3 , rotate the turning handle 31 to drive the swing rod 32 to rotate on the fixed block 33, and link the first clamping member 21 to slide on the control console 12, so as to drive the second clamping member 22 and the gravity block B to be suspended at a certain height relative to the support table 11 through the fabric A. At this time, it can be observed whether the fabric A starts to tear under the influence of the gravity block B. If the fabric A gradually tears along the bifurcated tear seam, it can be determined that the tear resistance of the fabric A is insufficient. If the fabric A does not produce any deformation, it can be determined that the tear resistance of the fabric A meets the requirements. The present utility model has a simple structure, and the whole can be manufactured and assembled by simple processes and simple parts, with extremely low manufacturing difficulty, which can save manufacturing costs, make the equipment more cost-effective, and benefit small fabric stores and companies.

[0045] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model. Through the inspiration of the present utility model or the above embodiments, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the field and / or the prior art, through logical analysis, reasoning or limited experiments, can obtain modifications, equivalent replacements or other improvements to the embodiments of the present utility model or some of its technical features, which should all be included in the protection scope of the present utility model.
