[0002] A tensile sensor, also known as a resistance strain gauge sensor, belongs to the series of weighing sensors. It is a device that converts physical signals into measurable electrical signal outputs. It uses two tensile transmission parts to transmit force. Its structure contains a force-sensitive device and two tensile transmission parts. The force-sensitive device contains a piezoelectric sheet and a piezoelectric sheet gasket, and the latter contains a substrate part and an edge force transmission part. In daily life, a tensile sensor with a positioning and installation function is often needed.

[0003] When a traditional tensile sensor is in use, it can only effectively weigh the items in a packaging bag through a hook, and cannot effectively perform fixed weighing on bulk items. When weighing bulk items, it is generally necessary to first tie up the bulk items or place them inside a packaging bag, which will cause a significant reduction in the weighing efficiency of the bulk items, and at the same time reduce the overall practicality of the tensile sensor, resulting in a relatively single weighing method for the tensile sensor. Moreover, the process of tying up bulk items is time-consuming and laborious, and also increases the workload of users.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 6 As shown in the figure, this embodiment provides a tensile sensor with a positioning and installation function, including a sensor body 1, and further including:

[0027] Support frames 2, symmetrically arranged outside the sensor body 1. Connecting plates 3 are fixedly connected to the outside of both support frames 2, and movable sleeves 4 are sleeved on the outside of both connecting plates 3;

[0028] Fixing components, respectively arranged outside both movable sleeves 4 and used to adjust the height position of the movable sleeves 4;

[0029] Fixing frames 6, respectively arranged at the bottoms of both movable sleeves 4. Fixing plates 7 are fixedly connected to the inside of both fixing frames 6;

[0030] Clamping components, arranged inside the fixing plates 7 and used to fixedly clamp block-shaped items.

[0031] The above working principle: When it is necessary to weigh block-shaped items, only by using the clamping components can the block-shaped items be conveniently and effectively fixedly clamped, so that the block-shaped items can be conveniently weighed through the sensor body 1, without the user having to bundle and package the block-shaped items, effectively improving the weighing efficiency of the block-shaped items, and improving the diversity of the weighing methods of the sensor body 1, enhancing the practicality of the sensor body 1. Through the setting of the fixing components, it is convenient for the user to adjust the height position of the clamping components, thereby further enhancing the overall practicality of the device, saving time and effort.

[0032] In order to effectively adjust the height position of the clamping assembly and further improve the overall practicality of the device, the fixing assembly includes fixing sleeves 5 respectively arranged outside the two movable sleeves 4. A fixing rod 15 is arranged inside the fixing sleeve 5. One end of the fixing rod 15 is fixedly connected with a pulling plate. A resisting disc 16 is fixedly connected to the outside of the fixing rod 15. A return spring 17 is sleeved on the outside of the fixing rod 15. The return spring 17 abuts between the resisting disc 16 and the fixing sleeve 5. Guide grooves for the movement of the fixing rod 15 are formed on the contact surfaces of the fixing sleeve 5 and the movable sleeve 4. Guide grooves for the movement of the fixing rod 15 are equidistantly formed inside the connecting plate 3. When it is necessary to adjust the height position of the clamping assembly, only need to first pull the pulling plate. At this time, the pulling plate will drive the fixing rod 15 to move synchronously. The fixing rod 15 will then drive the resisting disc 16 to move synchronously. During the movement of the resisting disc 16, the return spring 17 will be compressed. When the fixing rod 15 disengages from the guide groove inside the connecting plate 3, then pull the movable sleeve 4 outside the connecting plate 3. When the movable sleeve 4 drives the fixing plate 7 to move to the required height position, then release the pulling plate. At this time, the return spring 17 resets, driving the resisting disc 16 and the fixing rod 15 to move synchronously. When the fixing rod 15 is inserted into the guide groove inside the connecting plate 3, the height position of the clamping assembly can be fixed, thereby effectively improving the overall practicality of the device.

[0033] Taking into account that when weighing block objects, the block objects need to be fixed and clamped first, so the clamping assembly includes sliding rods 20 symmetrically arranged inside the fixed plate 7, and the two ends of multiple sliding rods 20 are fixedly connected to the two sides of the inner wall of the fixed plate 7 respectively. A movable plate 19 is provided inside the fixed plate 7, and a guide groove for the movement of the sliding rods 20 is opened inside the movable plate 19. The outsides of multiple sliding rods 20 are all sleeved with resistance springs 21, and the multiple resistance springs 21 are all in contact between the movable plate 19 and the fixed plate 7. The outside of the movable plate 19 is fixedly connected with a pull ring through a connecting rod 18, and the opposite sides of the two movable plates 19 are fixedly connected with an insert plate 8, and the opposite sides of the two insert plates 8 are fixedly connected with a 匚-shaped frame 9, and the insides of the two 匚-shaped frames 9 are provided with a clamping plate 10. When it is necessary to weigh the block objects, you only need to pull the pull ring first, and the pull ring will drive the connecting rod 18 to move synchronously. , the connecting rod 18 then drives the moving plate 19 to move synchronously on the outside of the sliding rod 20. During the movement of the moving plate 19, the resistance spring 21 will be squeezed, and the moving plate 19 will also drive the plug plate 8 to move synchronously, and the plug plate 8 will then drive the 匚-shaped frame 9 and the clamping plate 10 to move synchronously. At this time, the block object is placed between the two clamping plates 10, and the pull ring is released again. At this time, the resistance spring 21 is reset, driving the moving plate 19 to move synchronously, and the moving plate 19 will drive the plug plate 8 and the 匚-shaped frame 9 to move synchronously, and the 匚-shaped frame 9 will drive the clamping plate 10 to move synchronously. When the opposite sides of the two clamping plates 10 are in contact with the outside of the block object, the clamping plate 10 can be used to effectively fix and clamp the block object, so that the sensor body 1 can conveniently and effectively weigh the block object, effectively improving the diversity and practicality of the overall weighing method of the device.

[0034] In order to further improve the fixing effect of the device on block-shaped objects, rotating rods 14 are fixedly connected to both the front surface and the rear surface of the two clamping plates 10. The other ends of the two rotating rods 14 are rotatably connected to the inner wall of the U-shaped frame 9. The other ends of the other two rotating rods 14 extend to the outside of the U-shaped frame 9 and are fixedly connected with knobs 11. Anti-slip pads 12 are adhered to the opposite sides of the two clamping plates 10. Installation grooves for installing magnetic attraction blocks 13 are formed on the other sides of the two clamping plates 10. When it is necessary to fixedly clamp non-metallic block-shaped objects such as plastics and paper shells, the anti-slip pads 12 can effectively increase the friction between the non-metallic block-shaped objects and the clamping plates 10, thereby effectively improving the fixing effect of non-metallic objects. When it is necessary to fixedly clamp metal block-shaped objects, just rotate the knob 11 first. At this time, the knob 11 will drive the rotating rod 14 to rotate synchronously. The rotating rod 14 will then drive the clamping plate 10 to rotate synchronously. The clamping plate 10 will then drive the magnetic attraction block 13 to rotate synchronously. At this time, place the metal block-shaped object between the two clamping plates 10. The magnetic attraction block 13 can effectively adsorb and fix the metal object, thereby further improving the fixing effect of the metal object and further enhancing the overall practicality of the device.

[0035] In order to effectively fix the clamping plate 10, rotating gears 22 are fixedly connected to the outside of two of the rotating rods 14. Support plates 23 are fixedly connected to the front surfaces of the two U-shaped frames 9. Activity grooves for the movement of the pull rods 24 are formed through the interiors of the two support plates 23. Pulling disks are fixedly connected to one ends of the two pull rods 24. Clamping blocks 25 are fixedly connected to the other ends of the two pull rods 24. Clamping grooves for clamping the rotating gears 22 are formed on the opposite sides of the two clamping blocks 25. Connecting springs 26 are sleeved on the outside of the two pull rods 24. The two connecting springs 26 are both abutted between the clamping blocks 25 and the support plates 23. When it is necessary to flip the clamping plate 10, just pull the pulling disk first. At this time, the pulling disk will drive the pull rod 24 to move synchronously. The pull rod 24 will then drive the clamping block 25 to move synchronously. During the movement of the clamping block 25, the connecting spring 26 will be compressed. When the clamping block 25 disengages from the outside of the rotating gear 22, the knob 11 can be rotated. At this time, the knob 11 will drive the rotating rod 14 and the rotating gear 22 to rotate synchronously. After the clamping plate 10 is flipped, release the pulling disk. At this time, the connecting spring 26 resets and drives the clamping block 25 to move synchronously. When the clamping groove inside the clamping block 25 is inserted into the outside of the rotating gear 22, the rotating gear 22 and the knob 11 can be locked, and at this time, the clamping plate 10 can be fixed, thereby effectively improving the fixing effect of the clamping plate 10 on the block-shaped object.

[0036] In addition, in order to enable the sensor body 1 to weigh packaged bag-like items, a hanging hook 27 is provided at the bottom of the sensor body 1. When it is necessary to weigh the items inside the packaged bag, the packaged bag can be simply hung on the hanging hook 27. At this time, the sensor body 1 can be used to weigh the items inside the packaged bag.
