Description

Technical Field

[0001] The invention relates to the technical field of quality inspection, and in particular to a labor protection glove tension inspection device. Background Art

[0002] Labor protection gloves are gloves that protect your hands when working. Different workers have different quality requirements for labor protection gloves. For example, electricians have high requirements for the tensile strength of gloves. In order to ensure the quality of labor protection gloves, after the labor protection gloves are produced, they can be tested by tensile testing.

[0003] The patent with the patent authorization announcement number CN114354362A discloses a labor protection glove tension detection device, which includes a body, a mold is provided on the body, and the mold is in the shape of a hand as a whole, and one end of the mold is provided with five mutually parallel finger molds, each finger mold is arranged at equal intervals and corresponds to the finger sleeve part on the labor protection glove tension detection. The tension detection device detects the tension of the labor protection glove to be detected on the hand-shaped mold, clamps the top part of the glove finger sleeve through the traction ring, uses the telescopic cylinder to move the traction ring and stretch the glove, and uses the air pipe to inflate the glove finger sleeve at the same time, and uses the leakage detector to detect whether there is a gap on the glove tension detection surface, so as to achieve the purpose of tension detection of the labor protection glove. However, the tension detection device cannot be adjusted according to different situations. For example, the limit length of different finger sleeves is different, and the stretching length needs to be adjusted according to the length of the finger sleeve.

A contact rod 71 is fixedly connected to the left rear portion of the upper clamping plate 7, and a driving assembly is provided on the mounting plate 301, which can drive the lower clamping plate 5 to move left and right. A mounting frame 14 is fixedly connected to the left front portion of the base 1, and four equidistantly distributed fixed plates 15 are fixedly connected to the upper portion of the mounting frame 14. A sliding plate 16 is slidably connected to the fixed plate 15 for movement left and right, and the sides of the fixed plate 15 and the sliding plate 16 that are away from each other are both inclined. The contact rod 71 moves to the right and is squeezed upward by the sliding plate 16, and moves to the left and is squeezed downward by the fixed plate 15. A threaded rod 17 is rotatably connected to the rear side of the fixed plate 15, and the threaded rod 17 is threadedly connected to the adjacent sliding plate 16. A fixing mechanism is provided on the model frame 3, and the fixing mechanism can fix the labor protection gloves.

[0041] like Figure 1-Figure 4 As shown, the driving assembly includes a second guide rod 9, a sliding frame 10, a rodless cylinder 11, an insert plate 12 and a telescopic rod 13. The upper side of the mounting plate 301 is fixedly connected to a front-to-rear symmetrical second guide rod 9, a sliding frame 10 that moves left and right is slidably connected between the front and rear second guide rods 9, a rodless cylinder 11 is fixedly connected to the rear of the mounting plate 301, the sliding frame 10 is slidably connected to the rodless cylinder 11, the insert plate 12 is fixedly connected to the sliding frame 10, the telescopic rod 13 is fixedly connected to the lower side of the lower clamping plate 5, and the lower end of the telescopic rod 13 is inserted into the insert plate 12.

[0042] When using the device, the staff puts the labor protection gloves on the model frame 3, and then fixes them through the fixing mechanism. After fixing, the staff controls the sliding frame 10 to slide to the right through the rodless cylinder 11, and the sliding frame 10 slides to the right and drives the plug plate 12 to move to the right. The plug plate 12 moves to the right and drives the lower clamping plate 5 to move to the right through the telescopic rod 13. The lower clamping plate 5 moves to the right and drives the upper clamping plate 7 to move to the right through the vertical rod 6. The upper clamping plate 7 moves to the right and drives the contact rod 71 to move to the right. When the contact rod 71 moves to the right to contact with the sliding frame When the contact rod 71 moves to the right and disengages from the sliding plate 16, the contact rod 71 contacts the fixed plate 15, thereby causing the upper clamping plate 7 to continue to remain in the open state. When the contact rod 71 moves to the right and disengages from the fixed plate 15, the upper clamping plate 7 slides downward and resets under the action of the first spring 8. At this time, the upper clamping plate 7 and the lower clamping plate 5 are respectively in the position of the labor protection gloves. The finger position, and then the staff controls the sliding frame 10 to slide to the left through the rodless cylinder 11, the sliding frame 10 slides to the left through the plug plate 12 and the telescopic rod 13 to drive the lower clamping plate 5 to slide to the left, the lower clamping plate 5 slides to the left through the vertical rod 6 to drive the upper clamping plate 7 to move to the left, the upper clamping plate 7 moves to the left and drives the contact rod 71 to move to the left, the contact rod 71 moves to the left and is squeezed by the fixed plate 15 to move downward, thereby driving the upper clamping plate 7 to slide downward and cooperate with the lower clamping plate 5 to clamp the finger sleeve, the first spring 8 is deformed, at this time, the upper clamping plate 7 and the lower clamping plate 7 are The clamping plate 5 continues to move to the left to pull the finger sleeve to stretch for tensile testing. When the contact rod 71 moves to the left and is no longer squeezed by the fixed plate 15 and the sliding plate 16, the upper clamping plate 7 slides upward to release the finger sleeve under the action of the first spring 8 returning to its original position. At the same time, the staff can control the sliding plate 16 to slide left and right on the fixed plate 15 through the threaded rod 17. The longer the length of the joint between the sliding plate 16 and the fixed plate 15, the longer the finger sleeve is stretched. The staff can adjust the stretching length according to different finger sleeves to ensure the test effect.

[0043] like Figure 6 and Figure 7 As shown, the fixing mechanism includes a first connecting plate 18, a sliding sleeve 19, a tightening wheel 191, a connecting rod 20 and a tightening belt 21. The first connecting plate 18 is fixedly connected to the front right side of the model frame 3, and the sliding sleeve 19 is movably connected to the front of the first connecting plate 18. A circle of toothed protrusions is provided in the middle of the sliding sleeve 19 for clamping with the first connecting plate 18. A tightening wheel 191 that moves left and right is slidably connected in the sliding sleeve 19. A connecting rod 20 is fixedly connected to the front upper side of the first connecting plate 18, and a tightening belt 21 is fixedly connected to the connecting rod 20. The tail end of the tightening belt 21 passes around the right side of the model frame 3 and engages with the tightening wheel 191.

[0044] When using the device, the staff pulls the sliding sleeve 19 to slide to the right. After the sliding sleeve 19 slides to the right, it is no longer stuck by the first connecting plate 18. At this time, the staff can control the sliding sleeve 19 to rotate. The rotation of the sliding sleeve 19 drives the tightening wheel 191 to rotate. The tightening wheel 191 rotates to loosen the tightening belt 21. At this time, the staff puts the labor protection gloves on the model frame 3 so that the opening end of the labor protection gloves is located on the inner side of the tightening belt 21. Then the staff controls the sliding sleeve 19 to reverse. The reversal of the sliding sleeve 19 drives the tightening wheel 191 to reverse. The reversal of the tightening wheel 191 drives the tightening belt 21 to tighten. The gloves are fixed to the model frame 3 through the tightening belt 21. After the labor protection gloves are fixed, the staff controls the sliding sleeve 19 to slide to the left. After the sliding sleeve 19 slides to the left, it is stuck by the first connecting plate 18 again, and then the tightening belt 21 is fixed by the tightening wheel 191 to prevent the tightening belt 21 from loosening and affecting the fixing effect of the labor protection gloves. In this way, the labor protection gloves can be fixed on the model frame 3 for tension testing.

[0045] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 8 and Fig. 9 As shown, it also includes an adjusting mechanism, which can adjust the number of stretching finger sleeves. The adjusting mechanism includes a cross bar 22, a first guide rod 23, a first sliding rod 24 and a wedge block 25. The telescopic end of the telescopic rod 13 is fixedly connected to the cross bar 22, and four equidistantly distributed first guide rods 23 are fixedly connected to the upper side of the mounting plate 301. The first guide rod 23 is slidably connected to the first sliding rod 24 that moves left and right. The upper part of the first sliding rod 24 is fixedly connected to the wedge block 25. The wedge block 25 moves to the right to squeeze the adjacent cross bar 22 to move upward.

[0046] By setting the adjustment mechanism, the amount of finger sleeve stretching can be adjusted as needed, so as to stretch a single finger sleeve, further improving the accuracy of the test. The specific operation is as follows: when the amount of finger sleeve stretching needs to be adjusted, the staff pushes the first sliding rod 24 corresponding to the finger sleeve that does not need to be stretched to slide to the right, and the first sliding rod 24 slides to the right to drive the wedge block 25 to move to the right, and the wedge block 25 moves to the right to squeeze the cross bar 22 to move upward, and the cross bar 22 moves upward to drive the telescopic rod 13 to shorten, and the telescopic rod 13 is no longer stuck in the plug plate 12 after shortening, and at this time, the plug plate 12 moves backward When the finger sleeve 5 is stretched to the left, the telescopic rod 13 will not be moved to the right by the telescopic rod 13, so that the corresponding finger sleeve cannot be clamped. The staff controls the wedge block 25 and the cross bar 22 to squeeze and cooperate with the adjustable telescopic rod 13, thereby achieving the purpose of adjusting the stretching amount of the finger sleeve. When the test is completed, the staff controls the first sliding rod 24 to slide to the left, and the first sliding rod 24 slides to drive the wedge block 25 to move to the left and no longer squeeze the cross bar 22. Under the action of gravity, the telescopic rod 13 is extended and clamped in the plug plate 12. In this way, the stretching amount of the finger sleeve can be adjusted according to needs.

[0047] like Figure 1 and Fig.10 As shown, it also includes an inflation mechanism, which can detect whether the labor protection gloves are damaged. The inflation mechanism includes a chassis 26, an air pump 27 and a connecting pipe 28. The chassis 26 is fixedly connected to the upper right part of the base 1, and the air pump 27 is fixedly connected to the chassis 26. A connecting pipe 28 is connected between the air pump 27 and the model frame 3.

[0048] By setting up an inflation mechanism, air can be inflated into the protection gloves so as to detect whether the protection gloves are damaged. The specific operation is as follows: the staff starts the air pump 27, and the air pump 27 operates to inflate the model frame 3 through the connecting pipe 28. The model frame 3 injects air into the protection gloves. The staff determines whether the protection gloves are damaged by observing whether the protection gloves are leaking. When the detection is completed, the staff turns off the air pump 27. In this way, it is possible to detect whether the protection gloves are damaged.

[0049] like Figure 1 and Fig.11 As shown, a temperature control mechanism is also included, which can adjust the temperature. The temperature control mechanism includes a support plate 29 and a heater 30. The base 1 is fixedly connected to the front and rear symmetrical support plates 29, and the upper part of the support plate 29 is fixedly connected to the heater 30.

[0050] By setting a temperature regulating mechanism, the temperature can be adjusted to simulate the use quality of the labor protection gloves at different temperatures. The specific operation is as follows: when performing a tensile test, the staff starts the heater 30 and adjusts the temperature around the device through the heater 30 to simulate the use quality of the labor protection gloves at different temperatures. When the test is completed, the staff turns off the heater 30.

[0051] like Figure 1 , Fig.12 and Fig.13 As shown, it also includes a positioning mechanism, which can adjust the stretching position. The positioning mechanism includes a connecting frame 31, a second sliding rod 32, a rotating block 33, a clamping plate 34, a second guide rod 35, a limiting frame 36, a second spring 37 and a second connecting plate 38. The left rear portion of the base 1 is fixedly connected to the connecting frame 31, the upper portion of the connecting frame 31 is slidably connected to the second sliding rod 32 that moves left and right, the left portion of the second sliding rod 32 is rotatably connected to the rotating block 33, the upper portion of the connecting frame 31 is fixedly connected to the clamping plate 34, the rear heater 30 is fixedly connected to the second guide rod 35, the upper and lower portions of the second guide rod 35 are both slidably connected to the limiting frame 36 that moves up and down, a second spring 37 is connected between the upper and lower limiting frames 36 and the second guide rod 35, and the second connecting plate 38 is rotatably connected between the rear portion of the limiting frame 36 and the right portion of the second sliding rod 32.

[0052] When the finger sleeve is pulled to the left, the pulling force on the labor protection glove is not all concentrated on the fingers, and the palm part will also be stretched accordingly. By setting the adjustment mechanism, it can be ensured that the pulling force is concentrated on the fingers. The specific operation is as follows: the staff pulls the second sliding rod 32 to slide to the left, and the second sliding rod 32 slides to the left and pulls the upper and lower limit frames 36 to slide toward each other through the second connecting plate 38. The second spring 37 is deformed, and the limit frames 36 slide toward each other. The sleeve 19 is at the root of the finger of the labor protection glove, and the second sliding rod 32 slides to the left while driving the rotating block 33 to move forward. After the rotating block 33 moves to the left, the staff controls the rotating block 33 to rotate and snap into place. The second slide bar 32 is fixed in the card plate 34, so that the limit frame 36 keeps covering the work gloves. At this time, when the finger sleeves of the work gloves are stretched, the limit frame 36 blocks the palm position and the force points are mainly concentrated on the finger positions, thereby ensuring the effect of the tension test. When the test is completed, the staff controls the rotating block 33 to reverse and disengage from the card plate 34. At this time, under the action of the second spring 37 resetting, the upper and lower limit frames 36 slide back to back and reset. The limit frames 36 slide back to back and pull the second slide bar 32 to slide rightward and reset through the second connecting plate 38. In this way, the force and stretching position of the work gloves can be adjusted as needed.

[0053] like Figure 1 , Fig.14 and Fig.15 As shown, a covering mechanism is also included, which can cover the upper side of the heater 30. The covering mechanism includes a guide rail 39, a slider 40, a baffle 41, a clamping plate 42 and a torsion spring 43. The left and right sides of the heater 30 are fixedly connected with the guide rail 39, the slider 40 is slidably connected in the guide rail 39, a baffle 41 is fixedly connected between the two symmetrical sliders 40, a clamping plate 42 is rotatably connected to the upper middle part of the rear baffle 41, and a left-right symmetrical torsion spring 43 is connected between the clamping plate 42 and the rear baffle 41.

[0054] By setting up a covering mechanism, the upper side of the heater 30 can be covered to reduce heat loss. The specific operation is as follows: the staff pushes the slider 40 to slide upward in the guide rail 39, and the slider 40 slides upward to drive the baffle 41 to move upward. Since the guide rail 39 is arc-shaped and the baffle 41 is also arc-shaped as a whole, the baffles 41 on the front and rear sides will move upward in an arc shape and approach each other. Under the action of the torsion spring 43, the clamping plate 42 will rotate and then be clamped on the front baffle 41 to fix the positions of the two baffles 41. The baffle 41 covers the upper side of the heater 30 to reduce heat loss. When the device is used, the staff releases the clamping plate 42, and under the action of gravity, the baffle 41 drives the slider 40 to slide downward and reset.

[0055] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
