Description

Technical Field

[0001] This utility model belongs to the field of mechanical testing technology and relates to a detachable portable force measuring device. Background Technology

[0002] Force measurement is crucial in many fields of modern industrial production, scientific research, sports, and daily life. For example, in manufacturing, precise force measurement is essential for product assembly, component connection, and material performance testing. Traditional force measuring devices often have several limitations. While fixed, large-scale force measuring equipment offers high accuracy and a wide measurement range, its bulky size, considerable weight, and difficulty in movement make it unsuitable for flexible use in different scenarios. Furthermore, its complex installation and debugging require specialized facilities and technical personnel, limiting its application to specific laboratories or fixed factory workstations. Handheld force gauges, while relatively portable, have limited functionality, typically only suitable for simple push-pull force measurements, generally with a small measurement range, and thus have limitations in on-site testing applications under various working conditions.

[0003] Furthermore, with the increasing diversification and dynamism of people's work and life scenarios, the demand for convenient and quick accurate force measurement in different locations and under different working conditions is becoming more and more urgent. In particular, for situations where large force values ​​such as adhesive force are tested on-site, there is an urgent need for a new type of force measuring device that can ensure measurement accuracy and multifunctionality, as well as being detachable and easy to carry. This would fill the gaps in the flexibility and practicality of existing force measuring technologies, meet people's extensive needs for force measurement in various scenarios, improve work efficiency, reduce force measurement costs, and expand the scope of force measurement applications. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a detachable and portable force measuring device. This device uses a force sensor with a wide measuring range and high accuracy, supplemented by a lifting support system and a data display, to meet the force measuring needs under different working conditions. The device is detachable, easy to carry, simple to operate, and highly accurate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable portable force measuring device, characterized in that it includes a lifting support system and a force sensing system. The lifting support system includes a triangular support frame, a lifting compass, a threaded screw, and a fixed handwheel. The lifting compass is mounted on the triangular support frame, the threaded screw passes through the lifting compass, and the fixed handwheel is installed above the threaded screw. The force sensing system includes a force sensor, a display screen, and a hook. The force sensor is connected to the lower end of the threaded screw, and the hook is fixed to the lower end of the force sensor. The display screen is connected to the force sensor and can display the tension force applied to the force sensor.

[0006] A reinforcing rod is welded below the triangular support frame.

[0007] Multiple control levers are evenly distributed on the lifting compass.

[0008] The beneficial effects of this utility model are:

[0009] 1. The lifting support system and force sensing system of this device are detachable, making it easy to carry.

[0010] 2. This device can meet the mechanical testing requirements under complex working conditions and can be used for mechanical testing in complex environments such as construction sites and outdoor environments.

[0018] To make the structure, working principle and effects of this utility model clearer, this utility model will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Example: A detachable portable force measuring device, including a lifting support system (e.g., Figure 1 (as shown) and force sensing systems (such as) Figure 2 As shown in the figure, the lifting support system includes a triangular support frame 11, a lifting compass 12, a threaded screw 13, and a fixed handwheel 14, and the force sensing system includes a force sensor 21, a display screen 22, and a hook 23.

[0020] Specifically, the lifting compass 12 is mounted on the triangular support frame 11 and is rotatable. The threaded screw 13 passes through the lifting compass 12, and the fixed handwheel 14 is fixed above the threaded screw 13.

[0021] Specifically, the force sensor 21 is connected to the lower end of the threaded rod 13 by bolts, the lower end of the force sensor 21 is fixed with a hook 23, and the display screen 22 is connected to the force sensor 21 to display the tension force on the force sensor 21.

[0022] Specifically, a reinforcing rod 16 is welded below the triangular support frame 11 (e.g., Figure 1 (As shown).

[0023] Specifically, the lifting compass 12 has multiple control levers 15 evenly distributed on it (such as...). Figure 3 (As shown).

[0024] Working process: Connect the lifting support system and the force sensing system, that is, connect the force sensor 21 to the threaded rod 13 with bolts; Operator 1 holds the fixed handwheel 14, and operator 2 operates the control lever 15 on the lifting compass 12 to rotate the lifting compass 12 and adjust the height of the threaded rod 13, thereby adjusting the height of the hook 23 on the force sensor 21. After the height is appropriate, hang the hook 23 on the object to be measured. Operator 2 operates the control lever 15 on the lifting compass 12 to raise the force sensor 21 until the test is completed. The display screen 22 displays the test results. During this process, operator 1 holds the fixed handwheel 14 to prevent the threaded rod 13 from rotating.

[0025] Specific application examples:

[0026] To test the adhesion between the rubber product and the metal, the metal part and the rubber product are first bonded together with an adhesive. The metal part has a pre-drilled thread hole, which can be screwed on with a bolt ring. The hook (23) can be hung on the bolt ring.

[0027] Connect the lifting support system and the force sensing system, that is, connect the force sensor (21) and the threaded screw (13) with bolts; Operator 1 holds the fixed handwheel (14), and operator 2 operates the control lever (15) on the lifting compass (12) to rotate the lifting compass (12) and adjust the height of the threaded screw (13). Since operator 1 holds the fixed handwheel (14), the threaded screw can only move up and down and cannot rotate, thereby adjusting the height of the hook (23) on the force sensor (21). After the height is appropriate, hook (23) is hung on the bolt ring on the metal part. Operator 2 operates the control lever (15) on the lifting compass (12) to raise the force sensor (21) until the metal part is pulled off the rubber product. The display screen (22) displays the test results. During this process, operator 1 holds the fixed handwheel (14) to prevent the threaded screw (13) from rotating. During the whole process, the rubber product is pressed under the tripod (11) or the adhesion between the rubber product and the substrate is greater than the adhesion between the metal part and the rubber product.

[0028] Finally, it should be noted that the above-listed embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model; those skilled in the art should understand that many modifications can still be made to the present utility model; and all modifications directly derived from or associated with the content disclosed in the present utility model should be considered to be within the protection scope of the present utility model.
