Technical Field

[0001] The utility model relates to the technical field of rubber testing devices, in particular to a portable tensile machine for rubber testing. Background Art

[0002] Rubber is a highly elastic polymer material, usually made from the latex of rubber trees or synthetic rubber. It has high ductility and resilience, can return to its original shape after stretching, and has good wear resistance and aging resistance. Rubber can be widely used in the manufacture of tires, seals, pipes, rubber shoes, rubber pads and other products. It can also be used in medical equipment, industrial products, building materials and other fields. In rubber production, tensile testing is required.

[0003] The Chinese patent with announcement number CN215833131U discloses a tension detection device for finished rubber. The device can test the same data through two tension sensors and display them on a first display screen and a second display screen, thereby ensuring the accuracy of the data. Through the coordinated use of a first clamping groove, a first fixing frame, a first telescopic device, a first cylinder, a first extrusion plate, a second clamping groove, a second telescopic device, a second extrusion plate and a second cylinder, the clamp for clamping the rubber is clamped more stably and firmly, thereby improving the efficiency of tension detection and ensuring the accuracy of the data.

[0004] The structure of the fixing seat in the above-mentioned patent is fixed and has a long length, so that it needs to occupy a large space during transportation, resulting in low transportation efficiency and increased transportation costs. In addition, the above-mentioned patent needs to be moved manually or by mechanical equipment when transferring positions. This process is relatively cumbersome, thereby reducing the portability of use and making it difficult to move quickly between different workplaces or locations, limiting the application scope and flexibility of the device.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) The utility model drives two driving gears to rotate simultaneously through a driving mechanism, thereby driving the two first tooth plates and the two second tooth plates to move in opposite directions at the same time, and driving the two clamping mechanisms to move away from each other, so that the rubber can be tested for tension.

In addition, by adjusting the lowering height of the support plate, the height of the workbench can be adjusted to meet the needs of people of different heights, thereby improving the humanized design of the device.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 5 As shown, two mutually parallel first tooth plates 2 are slidably installed on the upper surface of the workbench 1, and two mutually parallel second tooth plates 3 are slidably installed on the inner side of the two first tooth plates 2 on the upper surface of the workbench 1. A driving gear 4 is installed on both sides of the upper surface of the workbench 1 through a rotating shaft 10, and the driving gear 4 is simultaneously meshed and connected with the first tooth plate 2 and the second tooth plate 3. When the driving gear 4 rotates, it can simultaneously drive the first tooth plate 2 and the second tooth plate 3 meshed therewith to move in opposite directions. A first connecting plate 5 is installed on the opposite surface of the two first tooth plates 2, and a second connecting plate 6 is installed on the opposite surface of the two second tooth plates 3. A fixing block 7 is installed on the upper surface of the first connecting plate 5 and the second connecting plate 6. A tension sensor 8 is installed on the outer surface of the fixing block 7. A clamping mechanism 9 is arranged on the outer side of the tension sensor 8. The tension sensor 8 is used to detect tension data, and the clamping mechanism 9 is used to fix the rubber to be detected. Its specific structure and working process are consistent with the comparative patent, and no further description is made here.

[0025] A driving mechanism 14 capable of driving two driving gears 4 to rotate simultaneously is provided at the bottom of the workbench 1. Through the setting of the driving mechanism 14, the two driving gears 4 can be driven to rotate simultaneously, and the first connecting plate 5 and the second connecting plate 6 can be driven to move in opposite directions at the same time, so as to perform tension testing on the rubber.

[0026] Support columns 12 are installed at the four corners of the bottom of the workbench 1, and universal wheels 13 are installed at the bottom of the support columns 12. Two display screens 11 are installed on the side surface of the workbench 1. The universal wheels 13 are arranged to facilitate the movement of the device, thereby improving the application range and flexibility of the device and making it portable. The data detected by the tension sensor 8 is displayed on the display screen 11. Two L-shaped connecting blocks 27 are connected to the outer surfaces of the first connecting plate 5 and the second connecting plate 6, and a slide bar 28 is installed at the end of the L-shaped connecting block 27. Four mutually parallel slide grooves 29 are opened inside the workbench 1, and the ends of the slide bars 28 are inserted in the slide grooves 29. A limit block 30 is installed at the end of the slide bar 28. The arrangement of the L-shaped connecting blocks 27 and the slide bars 28 can not only support the first connecting plate 5 and the second connecting plate 6, making them more smooth and stable when sliding, but also limit the sliding distance of the first connecting plate 5 and the second connecting plate 6 through the arrangement of the limit block 30 to prevent them from falling off.

[0027] The driving mechanism 14 includes two side blocks 15 installed at the bottom of the workbench 1, and a connecting shaft 16 is rotatably connected between the two side blocks 15. Two first bevel gears 17 are symmetrically installed on the outer surface of the connecting shaft 16. Second bevel gears 18 are installed at the bottom of the two rotating shafts 10, and the two second bevel gears 18 are respectively meshed and connected with the two first bevel gears 17. A motor 19 is installed on the outer surface of one side of the side blocks 15, and the output shaft of the motor 19 is connected to the connecting shaft 16. When the motor 19 is started, the connecting shaft 16 can be driven to rotate, and the two first bevel gears 17 on its surface can be driven to rotate. Since the first bevel gear 17 and the second bevel gear 18 are meshed with each other, the two rotating shafts 10 can be driven to rotate at the same time, and the two driving gears 4 can be driven to rotate, so as to achieve the purpose of driving the two clamping mechanisms 9 away from or close to each other.

[0028] A cross plate 20 is installed between the two support columns 12 on the same side, and a U-shaped frame 21 is penetrated on the cross plate 20. A support plate 22 is installed at the bottom of the two vertical rods of the U-shaped frame 21. A threaded rod 23 is rotatably connected between the cross plate 20 and the workbench 1, and the threaded rod 23 penetrates the cross rod of the U-shaped frame 21 and is threadedly connected with it. A hand wheel 24 is installed on the outer surface of the threaded rod 23, and the threaded rod 23 can be driven to rotate by rotating the hand wheel 24. Since the threaded rod 23 and the U-shaped frame 21 are threadedly connected, and the U-shaped frame 21 is limited by the cross plate 20, when the threaded rod 23 rotates, the U-shaped frame 21 can be driven to rise and fall vertically, thereby driving the support plate 22 to rise and fall. By lowering the support plate 22 and supporting it with the ground, the universal wheel 13 is lifted, which can ensure the stability of the device during use and is not prone to sliding. In addition, by adjusting the lowering height of the support plate 22, the height of the workbench 1 can be adjusted, thereby meeting the use of people of different heights and improving the humanized design of the device.

[0029] The outer surfaces of the two threaded rods 23 are sleeved with pulleys 25, and the two pulleys 25 are meshed with a transmission belt 26. Through the setting of the pulleys 25 and the transmission belt 26, when the threaded rod 23 on either side is rotated, the threaded rod 23 on the other side can be driven to rotate at the same time, so that the two support plates 22 can be raised and lowered at the same time, which not only improves the adjustment efficiency of the device, but also allows the device to maintain a stable state during adjustment, thereby improving portability. A rubber pad is provided at the bottom of the support plate 22, and the surface of the rubber pad is provided with anti-skid grooves. Through the setting of the rubber pad and the anti-skid grooves, the friction force when the threaded rod 23 contacts the ground can be increased, thereby improving the stability of the support of the support plate 22.

[0030] The working principle of the utility model is as follows: firstly, the two ends of the rubber to be detected are clamped and fixed by two clamping mechanisms 9 respectively, and then the motor 19 is started. The motor 19 drives the connecting shaft 16 to rotate, and drives the two first bevel gears 17 on its surface to rotate. Since the first bevel gear 17 and the second bevel gear 18 are meshed with each other, the two rotating shafts 10 can be driven to rotate at the same time, and the two driving gears 4 can be driven to rotate. Due to the meshing relationship between the driving gear 4 and the first tooth plate 2 and the second tooth plate 3, the two first tooth plates 2 and the two second tooth plates 3 can be driven to move outward at the same time, and the first connecting plate 5 and the second connecting plate 6 can be driven to move away from each other, so that the two clamping mechanisms 9 pull the rubber, and the tension sensor 8 displays the detected data on the display screen 11, thereby achieving the purpose of rubber tension detection. When the utility model needs to be tested, When the device is being transported, the motor 19 can be started to drive the connecting shaft 16 to rotate in the opposite direction, thereby driving the first connecting plate 5 and the second connecting plate 6 to approach each other and move to the upper surface of the workbench 1. At this time, the device can be miniaturized, thereby greatly reducing the occupied space, improving transportation efficiency, and thus reducing transportation costs. When the device needs to be moved, the hand wheel 24 can be rotated to drive the threaded rod 23 to rotate, and then the support plate 22 can be driven to rise and fall through the U-shaped frame 21. By raising the support plate 22 to a high place and allowing the universal wheel 13 to support the ground, the device can be easily pushed to move. When the device moves to the specified position, the hand wheel 24 can be rotated in the opposite direction to drive the support plate 22 to descend and re-support the ground, thereby improving the stability of the device and preventing it from sliding.

[0031] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
