Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a push-pull force gauge for electronic products. Background Art

[0002] A force gauge is an instrument used to measure force, capable of measuring various thrust and pull values. It is commonly used in industrial production, mechanical experiments, and materials testing. Force gauges can be categorized by their operating principle into mechanical, electronic, and digital types.

[0003] An existing Chinese patent, CN219608618U, is available for reference. It discloses a push-pull force gauge comprising a gauge body, a measuring base, and a mounting bracket to which the gauge body is secured. A measuring head is located at the lower end of the gauge body. The measuring base comprises a base plate and two clamping plates secured to the base plate. The mounting bracket is clamped between the two clamping plates. Multiple guide rods are provided between the inner flanges of the clamping plates and the base plate. These guide rods correspond to and extend through the first outer flange of the mounting bracket. Two clamping springs are provided between the bottom of the mounting bracket and the base plate. By clamping the object to be measured between the clamping springs and the base plate, the object is securely positioned, preventing displacement during measurement and preventing measurement errors. Furthermore, the gauge body is secured to the mounting bracket, which moves vertically downward along the guide rods, enabling the measuring head to act vertically on the object to be measured, preventing tilt and ensuring measurement accuracy.

[0004] Although this patent has the effect of preventing displacement during measurement, it still adopts the traditional base fixing method. When held in hand, its surface area is smooth. The reaction force generated during the pulling process may cause the device to slide from the hand to the ground, thereby affecting the device and is more likely to affect the subsequent detection accuracy. Therefore, when performing handheld operation, its structure needs to be further processed and improved, which increases the process and reduces work efficiency. For this reason, the inventors have proposed a push-pull force gauge for electronic products to solve the above-mentioned technical problem of reducing the device from sliding from the hand to the ground during handheld force measurement operations. Utility Model Content

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0007] After receiving the light change information from the photosensor, the signal converter converts the light signal into an electrical signal, and after amplification, filtering and other processing, generates a pulse signal output. The specific process includes: the photosensor senses the change in light intensity and generates corresponding current or voltage changes; the signal converter converts this analog signal into a digital pulse signal to facilitate the display to process subsequent circuits.

[0008] Furthermore, the protective sleeve and the shell are of a detachable structure, the protective sleeve and the connecting protrusion are integrally formed, the connecting protrusion is a circular protrusion and is linearly arranged at one end of the protective sleeve, the distance between two adjacent connecting protrusions is equidistant, and the surface of the shell is provided with a positioning groove that is matched with the connecting protrusion, and the positioning groove is a concave structure; when the positioning groove is connected to the connecting protrusion, a contact point is formed between the positioning groove and the connecting protrusion, thereby increasing the force area of the surface of one end of the protective sleeve, thereby increasing the friction force. In addition, the cooperation of the concave and convex structure increases the connection performance between the protective sleeve and the shell, which is convenient for the user to avoid the protective sleeve falling off from the surface of the shell when pulling the shell during the force measurement process.

[0009] Furthermore, the surface of the protective cover is provided with anti-slip grooves, which are located between two adjacent connecting protrusions. The anti-slip grooves are in the shape of stripes, and the two adjacent anti-slip grooves are arranged in a corresponding structure, and the highest point is flush with the surface of the protective cover. The anti-slip grooves increase the force points on the surface of one end of the protective cover, thereby increasing the friction and reducing the probability of the protective cover falling off from the shell surface. In addition, by cooperating with the connecting protrusions, the connection stability between the protective cover and the shell is further increased.

[0010] Furthermore, the pulling assembly includes a rotating shaft, a turntable and a pull wire, the two ends of the rotating shaft are respectively in contact with the surfaces of the code disk and the pull wire, and one end of the rotating shaft passes through the middle of the turntable, and the turntable is used to limit the position of the rotating shaft; this structure can accurately control the rotation angle and position of the rotating shaft to ensure the accuracy and consistency of the operation. When the code disk rotates, the surface of the code disk contacts the photosensor. When the weight of the object is different, the frequency of the code disk rotation will also change. When the code disk rotates, the photosensor will be affected by the frequency of the code disk rotation, and the resulting light change will form a tiny resistance.

[0012] By connecting the pull wire through the wire hole, the pull wire can easily pull the rotating shaft, which is convenient for the operator to operate. In addition, the connection between the pull wire and the reversing wheel, the rotating shaft and the shell makes the entire code disk more stable during the movement of the turntable. By using the wire hole, the complex mechanical connection structure can be reduced, the manufacturing cost can be reduced, and the force can be quickly adjusted by pulling the wire, thereby improving work efficiency.

[0013] Furthermore, the surface of the protective sleeve is connected to a positioning rod, which is used to connect to the surface of the shell; the surface of the shell can be provided with a hole for matching with the positioning rod, and the positioning rod is connected to the surface of the protective sleeve, which can more accurately fix and position the shell, thereby improving assembly efficiency and structural stability. The outer side surface of the protective sleeve is provided with a folding angle for facilitating hand grasping, and the folding angle is set at an angle; the inclined setting facilitates hand grasping, improves grip comfort, and increases grip stability, making operation more convenient and accurate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: by adding a protective component to the outside of the shell, the protective component includes a protective sleeve and a connecting protrusion, the protective sleeve increases the force-bearing area, thereby increasing the friction force, reducing the shell and the protective sleeve from slipping in the hand during the pulling process, preventing the shell and the protective sleeve from being separated from the user's hand due to the pulling force, and further preventing the subsequent falling to the ground or the impact force caused by the force;

[0015] The connecting protrusions further increase the connection stability between the shell and the protective sleeve. The protective sleeve is made of soft rubber, which can effectively reduce the damage to the shell when it is impacted and play a buffering role. The connecting protrusions are made of hard rubber, which further increases the force points between the shell and the protective sleeve, increasing the connection stability while playing a buffering role.

[0016] On the other hand, the interior of the protective cover is filled with a buffer spring. When the surface of the protective cover is affected by impact force, it is initially buffered by the buffering performance of its soft rubber itself, and then rebounds again through the buffer spring to play a secondary buffering role, further reducing the damage caused by the impact force to the shell and playing a role in protecting the shell.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0025] For this example, please refer to Figures 1-6, a push-pull force gauge for electronic products is specifically implemented, comprising a shell 1 and a display 2, wherein the display 2 is located on the surface of the shell 1, and one end of the display 2 is a display screen 3 for displaying the pulling value. A force measuring component is provided inside the shell 1, and the force measuring component comprises a code disk 4 and a photosensor 5. One end of the code disk 4 abuts the surface of the photosensor 5, and one end of the display 2 is electrically connected to a main control circuit board 6. A signal converter 7 for converting the pulse signal of the photosensor 5 is mounted on the surface of the main circuit board 6, and one end of the signal converter 7 is electrically connected to the display 2. A protective component is provided on the surface of the shell 1, and the protective component comprises a protective sleeve 8 and a connecting protrusion 9. The protective sleeve 8 is made of soft rubber, and the connecting protrusion 9 is made of hard rubber. One end of the code disk 4 is connected to a pulling component, and the interior of the protective sleeve 8 is filled with a buffer spring 21. When the surface of the protective sleeve 8 is affected by an impact force, it is initially buffered by the buffering performance of the soft rubber itself, and then rebounded again by the buffer spring 21 to play a secondary buffering role, further reducing the damage caused by the impact force to the shell 1, thereby protecting the shell 1;

[0026] After receiving the light change information from the photosensor 5, the signal converter 7 converts the light signal into an electrical signal, and after amplification, filtering and other processing, generates a pulse signal output. The specific process includes: the photosensor 5 senses the changes in light intensity and generates corresponding current or voltage changes; the signal converter 7 converts this analog signal into a digital pulse signal to facilitate the display 2 to process subsequent circuits.

[0027] The protective sleeve 8 and the shell 1 are of a detachable structure. The protective sleeve 8 and the connecting protrusion 9 are integrally formed. The connecting protrusion 9 is a circular protrusion and is linearly arranged at one end of the protective sleeve 8. The distance between two adjacent connecting protrusions 9 is equidistant. The surface of the shell 1 is provided with a positioning groove 10 that is matched with the connecting protrusion 9, and the positioning groove 10 is a concave structure; when the positioning groove 10 is connected to the connecting protrusion 9, a contact point is formed between the positioning groove 10 and the connecting protrusion 9, thereby increasing the force-bearing area of the surface of one end of the protective sleeve 8, thereby increasing the friction force. In addition, the cooperation of the concave and convex structure increases the connection performance between the protective sleeve 8 and the shell 1, which is convenient for the user to prevent the protective sleeve 8 from falling off the surface of the shell 1 when pulling the shell 1 during the force measurement process.

[0028] The surface of the protective sleeve 8 is provided with anti-slip grooves 11, and the anti-slip grooves 11 are located between two adjacent connecting protrusions 9. The anti-slip grooves 11 are in the shape of stripes. The two adjacent anti-slip grooves 11 are arranged in a corresponding structure, and the highest point is flush with the surface of the protective sleeve 8; the anti-slip grooves 11 increase the force points on the surface of one end of the protective sleeve 8, thereby increasing the friction force and reducing the probability of the protective sleeve 8 falling off from the surface of the shell 1. In addition, by cooperating with the connecting protrusions 9, the connection stability between the protective sleeve 8 and the shell 1 is further increased.

[0029] The pulling assembly includes a rotating shaft 12, a turntable 13 and a pull wire 14. The two ends of the rotating shaft 12 are respectively in contact with the surfaces of the code disk 4 and the pull wire 14. One end of the rotating shaft 12 passes through the middle of the turntable 13. The turntable 13 is used to limit the position of the rotating shaft 12. This structure can accurately control the rotation angle and position of the rotating shaft 12 to ensure the accuracy and consistency of the operation. When the code disk 4 rotates, the surface of the code disk 4 contacts the photosensor 5. When the weight of the object is different, the frequency of rotation of the code disk 4 will also change. When the code disk 4 rotates, the photosensor 5 will be affected by the rotation frequency of the code disk 4, and the resulting light change will form a small resistance. The change signal is amplified, processed, and converted into a digital signal through the signal converter 7, and finally displayed on the display screen 3 of the display 2.

[0030] One end of the pull wire 14 is connected to a hook 15, a base 16 is installed at the bottom of the turntable 13, a reversing wheel 17 is connected to the surface of the base 16, the pull wire 14 is wound around the surface of the reversing wheel 17, one end of the reversing wheel 17 is in contact with the surface of the rotating shaft 12, and a wire hole 18 for use with the pull wire 14 is opened on the surface of the housing 1;

[0031] By connecting the pull wire 14 through the wire hole 18, the pull wire 14 can easily pull the rotating shaft 12, which is convenient for the operator to operate. In addition, the connection between the pull wire 14 and the reversing wheel 17, the rotating shaft 12 and the shell 1 makes the entire code disk 4 more stable during the movement of the turntable 13. By using the wire hole 18, the complex mechanical connection structure can be reduced, the manufacturing cost can be reduced, and the force can be quickly adjusted by means of the pull wire 14, thereby improving work efficiency.

[0032] The surface of the protective sleeve 8 is connected to a positioning rod 19, which is used to connect to the surface of the shell 1; the surface of the shell 1 can be provided with a hole for matching with the positioning rod 19, and the positioning rod 19 is connected to the surface of the protective sleeve 8, which can more accurately fix and position the shell 1, thereby improving assembly efficiency and structural stability. The outer side surface of the protective sleeve 8 is provided with a folding angle 20 for facilitating hand grasping, and the folding angle 20 is set at an angle; the inclined setting facilitates hand grasping, improves grip comfort, and increases grip stability, making operation more convenient and accurate.

[0033] The key points of the design of the present invention are: by adding a protective component to the outside of the shell 1, the protective component includes a protective sleeve 8 and a connecting protrusion 9, the protective sleeve 8 increases the force-bearing area, thereby increasing the friction force, reducing the shell 1 and the protective sleeve 8 from slipping in the hand during the pulling process, and preventing the shell 1 and the protective sleeve 8 from being separated from the user's hand due to the pulling force, further preventing the subsequent falling to the ground or the impact force caused by the force;

[0034] The connecting protrusion 9 further increases the connection stability between the shell 1 and the protective sleeve 8. The protective sleeve 8 is made of soft rubber, which can effectively reduce the damage suffered by the shell 1 when it is impacted and play a buffering role. The connecting protrusion 9 is made of hard rubber, which further increases the force points between the shell 1 and the protective sleeve 8, thereby increasing the connection stability and playing a buffering role.

[0035] On the other hand, when the surface of the protective cover 8 is affected by the impact force, it is initially buffered by the buffering performance of its soft rubber itself, and then rebounds again through the buffer spring 21 to play a secondary buffering role, further reducing the damage caused by the impact force to the shell 1 and playing a role in protecting the shell 1.

[0036] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions.
