Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a Martindale assistor device which is convenient to open. Background Art

[0002] The Martindale abrasion tester is a testing equipment used to evaluate the abrasion resistance and pilling degree of fabrics under pressure. In the prior art, the driving mechanism of the Martindale abrasion tester includes a motor and a speed reducer, which drives the crank to rotate through a synchronous belt and a synchronous pulley. The looseness or tightness of the synchronous belt will cause the eccentricity of the crankshaft, resulting in the deformation of the Lissajous curve and affecting the repeatability and comparability of the test results.

[0003] In view of the above problems, the patent document with the authorization announcement number CN209624279U discloses a Martindale abrasion and pilling tester. The driving mechanism of the tester includes at least two motors, each motor corresponding to a crank. A chute is provided on the moving plate, and the crank is slidably arranged in the chute. The motor is arranged horizontally in the workbench and is drivingly connected to the crank. By driving the crank to rotate through the motor, the moving plate is moved horizontally; the tester drives a single crank by a single motor to avoid using a synchronous belt and a synchronous pulley, effectively preventing the generation of errors, improving the accuracy of the test, and making the test results repeatable and comparable.

[0004] In the above tester, the sample is fixed at the bottom end of the grinding head through a sample clamp. When removing or clamping the sample, it is necessary to separate the sample clamp from the grinding head, and then manually tighten the sample clamp and the grinding head after the sample is placed or taken out. In order to facilitate the separation and tightening of the sample clamp and the grinding head, vertical stripes are provided on the side of the grinding head to increase the friction between the hand and the grinding head. However, when detecting a large number of products, the frequency of friction between the operator's hand and the vertical stripes is relatively high, which will cause the hand to turn blue, purple, red and swollen, affecting the comfort of the operator and thus reducing the work efficiency. Summary of the Utility Model

[0005] The utility model provides a Martindale assistor device which is convenient to open, so as to solve the technical problem that when detecting a large number of products in the prior art, the high friction frequency between the vertical stripes on the grinding head and the operator's hand leads to the reduction of the operator's comfort and work efficiency.

[0006] In order to solve the above problems, the Martindale assistor device which is convenient to open provided by the utility model adopts the following technical scheme:

[0007] A Martindale assistor device which is convenient to open, comprising:

[0008] A device main body, which includes a vertical section, a rotating rod is connected to the top of the vertical section, a horizontal section is connected to the bottom, and a cavity extending vertically and communicating up and down is provided in the vertical section and the horizontal section;

[0009] A clamping structure, which is located at the bottom of the horizontal section and is slidably connected to the horizontal section, and the clamping structure includes two or more clamping members;

[0010] A driving structure, which is installed in the cavity. The driving structure includes a driving rod, a rotating shaft and a transmission rod connected in sequence from top to bottom. The driving rod and the transmission rod are respectively hinged to the upper and lower sides of the rotating shaft. The top of the driving rod is hinged with a pressing member, and the bottom of the transmission rod is hinged to the top of the clamping member. The pressing member is used to drive the clamping members to move away from each other through the driving structure after being pressed;

[0011] A self - resetting member is arranged between the clamping member and the horizontal section to drive the clamping member and the driving structure to reset after the pressure applied to the pressing member disappears;

[0012] The number of the driving rod, the rotating shaft and the transmission rod matches the number of the clamping members.

[0013] The beneficial effect of the Martindale assistor device provided by the present utility model that is easy to open is as follows: By pressing the pressing member, the driving rod, the rotating shaft and the transmission rod can be driven to move in sequence, and then the clamping member can be driven to move relative to the horizontal section, so that the clamping members move away from each other, thereby forming a clamping position for clamping the grinding head. Place the grinding head between the clamping members, and then release the button. The clamping members can approach each other under the drive of the self - resetting member to clamp the grinding head. Subsequently, rotate the rotating rod to separate or tighten the grinding head from the sample clamp. The structure is simple and the operation is convenient, without the operator's hand directly contacting the grinding head. Through the above settings, the present utility model effectively solves the technical problem in the prior art that when detecting a large number of products, the high friction frequency between the vertical lines on the grinding head and the operator's hand reduces the operator's comfort and work efficiency.

[0014] Further, the top of the clamping member has a convex block, the bottom of the transmission shaft is hinged to the convex block, and the bottom of the horizontal section has a chute for accommodating the convex block. The transmission shaft drives the convex block to slide in the chute to achieve the sliding connection between the clamping member and the horizontal section.

[0015] Further, the self - resetting member is a spring. One end of the spring is connected to the convex block, and the other end is connected to the side wall of one end of the chute.

[0016] Further, the centers of the vertical section, the horizontal section and the pressing member are on the same straight line.

[0017] Further, the horizontal section is a cylindrical structure, and a groove for accommodating a pressure rod installed on the top of the grinding head is provided at the center of the bottom.

[0018] Further, the number of the clamping members is two, and the two clamping members are respectively located at two opposite sides of the bottom of the horizontal section.

[0019] Further, the number of the driving rods is also two, and the tops of the two driving rods intersect and are hinged to the pressing member.

[0020] Further, the clamping member is a rubber block.

[0021] Further, the rotating rod is perpendicular to the vertical section.

[0022] Further, the pressing member is a cylindrical button. Description of the Drawings

[0033] It should be noted that the main concept of the easily opened Martindale assistor device provided by the present utility model is as follows: by pressing the pressing member to drive the driving rod, the rotating shaft and the transmission rod to move in sequence, the clamping members move away from each other to form a clamping position. After the grinding head is placed between the clamping members, the button is released, and the clamping members approach each other under the drive of the self-resetting structure, thereby clamping the grinding head. After clamping, hold the rotating rod at the upper end of the device main body and rotate it to separate or tighten the grinding head and the sample clamp.

[0034] After introducing the basic principle of the present utility model, the various non-limiting embodiments of the present utility model will be specifically introduced below. The number of any element in the accompanying drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0035] Next, with reference to several representative embodiments of the present utility model, the principles and spirits of the present utility model will be elaborated in detail.

[0036] Embodiment 1 of the easily opened Martindale assistor device provided by the present utility model:

[0037] As Figures 1 to 6 shown, the easily opened Martindale assistor device includes a device main body, a clamping structure, a driving structure and a self-resetting member. Among them, the device main body includes a vertical section 1, the top of the vertical section 1 is connected with a rotating rod 2, the bottom is connected with a horizontal section 3, and there is a cavity 4 extending vertically and communicating up and down in the vertical section 1 and the horizontal section 3. The driving structure is installed in the cavity 4, the clamping structure is slidably installed at the bottom of the horizontal section 3, and the self-resetting member is connected with the clamping structure and the horizontal section 3.

[0038] Specifically, the horizontal section 3 is a cylindrical structure, and a groove 12 for accommodating a pressure rod 11 installed at the top of the grinding head 10 is provided at the center of the bottom.

[0039] Regarding the clamping structure. The clamping structure includes two clamping members arranged on two opposite sides of the bottom of the horizontal section 3. The clamping members are rubber blocks 5. The top of the rubber block 5 has a convex block 15, and the bottom of the horizontal section 3 has a sliding groove 13 for accommodating the convex block 15, and the sliding connection between the rubber block 5 and the horizontal section 3 is realized by the sliding of the convex block 15 in the sliding groove 13.

[0040] Regarding the driving structure. The driving structure is installed in the cavity 4 and includes a driving rod 6, a rotating shaft 7, and a transmission rod 8 that are connected in sequence from top to bottom. The upper and lower ends of the rotating shaft 7 are respectively hinged to the driving rod 6 and the transmission rod 8. A pressing member is hinged to the top of the driving rod 6, and the bottom of the transmission rod 8 is hinged to the convex block 15.

[0041] Specifically, the number of the driving rods 6, the rotating shafts 7, and the transmission rods 8 is two, and the tops of the two driving rods 6 intersect and are hinged to the pressing member.

[0042] Specifically, the pressing member is a cylindrical button 9.

[0043] Regarding the self - resetting member. The self - resetting member is a spring 14, one end of which is connected to the convex block 15, and the other end is connected to the side wall of one end of the sliding groove 13, so as to be compressed when the convex block 15 slides in the sliding groove 13, and automatically rebound after the force acting on the button 9 disappears, forcing the convex block 15 to reset, thereby resetting the transmission rod 8, the rotating shaft 7, the driving rod 6, and the button 9.

[0044] In addition, the centers of the vertical section 1, the horizontal section 3, and the button 9 are on the same straight line, and the rotating rod 2 is perpendicular to the vertical section 1.

[0045] The working principle of the easy - to - open Martindale auxiliary device provided by the present utility model is as follows: When it is necessary to separate or tighten the grinding head 10 and the sample clamp, press the button 9 to move the driving rod 6 outward, so as to drive the rotating shaft 7 to rotate, thereby driving the transmission rod 8 to move outward. The transmission rod 8 drives the convex block 15 to move outward, so that the rubber blocks 5 move away from each other, and the spring 14 is compressed. Then, place the pressing rod 11 in the groove 12, and the grinding head 10 is located between the two rubber blocks 5. Release the button 9, and the spring 14 rebounds, prompting the two convex blocks 15 to approach each other to clamp the grinding head 10. At the same time, the transmission rod 8, the rotating shaft 7, the driving rod 6, and the button 9 perform a reset movement under the action of the resilience of the spring 14. Finally, rotate the rotating rod 2 to separate or tighten the grinding head 10 and the sample clamp.
