[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 8 , a hand dynamometer 100 provided in an embodiment of the utility model includes a housing 10 , a circuit board 20 , a sensor 30 and a force-bearing structure 40 .

[0029] Among them, see Figures 1 to 4 The shell 10 serves as an installation carrier, has a receiving cavity 11, and can be held by a hand; the circuit board 20 is arranged in the receiving cavity 11, and is used to transmit signals with the display terminal; the sensor 30 is arranged in the receiving cavity 11, and is electrically connected to the circuit board 20, and is used to receive the pressure signal of the hand and transmit it to the circuit board 20; the force-bearing structure 40 is arranged in the receiving cavity 11, including a mounting frame 41, a rotating lever 42 and an elastic member 43, the mounting frame 41 is used to limit the installation of the rotating lever 42, one end of the rotating lever 42 is rotatably arranged relative to the shell 10 and the mounting frame 41, and the other end is abutted against one end of the elastic member 43, and the other end of the elastic member 43 is abutted against the inner wall of the shell 10, so as to receive the pressing force from the hand, thereby driving the rotating lever 42 to rotate, so as to apply pressing force to the sensor 30 through the rotation of the rotating lever 42.

[0030] The above-mentioned hand dynamometer 100 can be held by the hand, so it has the characteristic of being small and compact. The shell 10 is used as the installation base, the pressing pressure of the hand is received by the sensor 30, and the signal is transmitted through the circuit board 20 and the external display terminal to display the pressing pressure of the hand through the display terminal. When the hand pressure is tested by the hand dynamometer 100, the main shell 10 is held by the hand, and pressing pressure is applied to the elastic member 43. The elastic member 43 is subjected to pressure and drives the rotating lever 42 to rotate relative to the mounting frame 41 and the shell 10. The rotated rotating lever 42 applies pressing pressure to the sensor 30. In this way, the sensor 30 transmits the received pressure signal to the circuit board 20, and the circuit board 20 transmits the electrical signal to the display terminal, and finally the hand pressing limit number is displayed through the display terminal, thereby facilitating the test and use by hand rehabilitation patients.

[0031] Among them, see Figures 1 to 4 The shell 10 of this embodiment includes an upper shell 12 and a lower shell 13 that are relatively slidably arranged. The upper shell 12 and the lower shell 13 together form a receiving chamber 11. The upper shell 12 and the elastic member 43 are abutted against each other so as to receive the pressing force from the hand. In this way, when the upper shell 12 receives the pressing force from the hand, it slides relative to the lower shell 13 and compresses the elastic member 43, so as to drive the rotating lever 42 to rotate through the elastic member 43.

[0032] Specifically, see Figure 2 as well as Figures 4 to 7 When the upper shell 12 is installed relative to the lower shell 13, the upper shell 12 includes an outer wall 121 and a first hook 122 disposed on the outer wall 121, and the lower shell 13 is provided with a second hook 131. When the handgrip dynamometer is in a pressed state, the first hook 122 and the second hook 131 are hung together to prevent the upper shell 12 from being separated from the lower shell 13. When the upper shell 12 is pressed, the first hook 122 slides along the inner wall of the lower shell 13, thereby realizing the sliding of the upper shell 12 relative to the lower shell 13.

[0033] For further information, see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In order to avoid data errors due to external pressure when the hand dynamometer is not in use, the hand dynamometer 100 also includes a reset switch 50. The reset switch 50 is electrically connected to the circuit board 20. When the reset switch 50 is pressed, the circuit board 20 receives a signal to make the display terminal display the data as 0. For example, in order to avoid data transmission due to pressing the sensor 30 when the hand dynamometer is installed because the elastic member 43 is elastic, the reset switch 50 is reset to make the display terminal display the initial data.

[0034] Since the reset switch 50 needs to protrude from the housing 10 , specifically, a first through hole 132 is provided on the lower housing 13 , and the first through hole 132 is used to install the reset switch 50 so that the reset switch 50 can be exposed.

[0035] Among them, see Figure 4 and Figure 5 In order to facilitate the installation of the reset switch 50, when the reset switch 50 is installed on the lower shell 13, the reset switch 50 and one end of the mounting frame 41 are abutted against each other, that is, a holding force is applied to the reset switch 50 through the end of the mounting frame 41 to press the reset switch 50 to be installed on the lower shell 13.

[0036] Understandably, see Figure 2 and Figure 4 Since the circuit board 20 needs to be powered to maintain normal use, the hand dynamometer 100 also includes a power supply 60. The power supply 60 is supported by the mounting frame 41 and is electrically connected to the circuit board 20 and the power supply 60 in sequence. By arranging the power supply 60 in the housing 10, the hand dynamometer can be conveniently carried and used anytime and anywhere.

[0037] Furthermore, in order to facilitate charging of the power supply 60, the hand dynamometer 100 also includes a charging connector 70, which is installed on the circuit board 20, and is electrically connected to the circuit board 20 and the power supply 60 in sequence, and can be exposed relative to the shell 10. That is, through the setting of the charging connector 70, the power supply 60 can be conveniently charged, and there is no need to unplug the power supply 60 for replacement each time, thereby further facilitating the use of the hand dynamometer.

[0038] Understandably, see Figure 2 A second through hole 134 is defined on the lower shell 13 , and the charging connector 70 is exposed relative to the second through hole 134 .

[0039] For further information, see Figure 1 and Figure 2 In order to facilitate the use of hand rehabilitation patients, a hanging hole 14 is provided on the shell 10. Specifically, a hanging hole 14 is also provided on the lower shell 13, so that a rope can be hung through the hanging hole 14 to tie the rope to the patient's hand for use to avoid the risk of falling.

[0040] See also Figure 5 and Figure 8 In one embodiment of the utility model, the mounting frame 41 includes a limiting portion 411 and a mounting portion 412. The limiting portion 411 is provided with an installation space 4111 for a rotating lever 42. The rotating lever 42 can rotate in the installation space 4111. The mounting portion 412 and the circuit board 20 are arranged in parallel for installation with the housing 10, specifically, with the lower housing 13, so that the circuit board 20 is clamped between the mounting portion 412 and the housing 10. In this way, the mounting frame 41 is arranged in two parts, the installation of the rotating lever 42 is limited by the limiting portion 411, and the installation of the circuit board 20 is achieved by installing with the housing 10.

[0041] Specifically, the limiting portion 411 includes two clamping plates 4112 arranged in parallel, and an installation space 4111 is formed between the two clamping plates 4112. The rotating lever 42 is rotatably arranged in the installation space 4111. The installation portion 412 is in a flat plate shape and is respectively arranged perpendicular to the two clamping plates 4112. A first installation column 4121 is arranged on the installation portion 412, and a second installation column 135 is arranged on the lower shell 13. The first installation column 4121 and the second installation column 135 are arranged correspondingly, so that the circuit board 20 is clamped between the lower shell 13 and the installation portion 412 through the threaded connection of the first installation column 4121 and the second installation column 136, that is, the installation of the circuit board 20 is achieved.

[0042] Among them, see Figure 4 and Figure 7When the sensor 30 is installed, a support platform 133 is provided in the shell 10, and the sensor 30 is arranged between the support platform 133 and the limiting portion 411. In this way, by providing the support platform 133 in the lower shell 13, the installation of the sensor 30 can be limited, and the fixing of the mounting frame 41 is achieved through the connection between the first mounting column 4121 and the second mounting column 35. In this way, the fixed mounting frame 41 also limits the sensor 30 on the support platform 133.

[0043] For further information, see Figure 5 and Figure 8 In order to achieve the installation limit of the reset switch 50, a limit step 413 is provided at one end of the clamping plate 4112, and the mounting portion 412 also includes a supporting platform 414. When installing, the reset switch 50 is respectively installed on the limit step 413 and the supporting platform 414, thereby achieving the installation limit of the reset switch 50.

[0044] See also Figure 1 , Figure 2 as well as Figure 4 In one embodiment of the utility model, when the rotating lever 42 rotates, the handgrip dynamometer 100 also includes a support shaft 80, and the support shaft 80 is passed through the shell 10 and the mounting frame 41, and is used for the rotating lever 42 to rotate. Specifically, the support shaft 80 of this embodiment is a steel rod, so that the support shaft 80 has a certain supporting strength.

[0045] Specifically, please refer to 7. When the support shaft 80 is installed, a second guide column 136 is provided on the lower shell 13. The support shaft 80 passes through the second guide column 136 to support the support shaft 80 through the second guide column 136, thereby increasing the supporting area of ​​the support shaft 80.

[0046] See also Figure 2 as well as Figures 4 to 6 In order to install the elastic member 43, a first guide sleeve 123 is provided on the upper shell 12, and a second guide sleeve 421 is provided on the rotating lever 42. The elastic member 43 is partially accommodated in the first guide sleeve 123 and partially accommodated in the second guide sleeve 421. In this way, the elastic member 43 is installed by the first guide sleeve 123 and the second guide sleeve 421, and the extension and contraction of the elastic member 43 can be guided to prevent the elastic member 43 from being skewed during the extension and contraction process and affecting the force test result.

[0047] For further information, see Figure 6 The upper shell 12 is also provided with a first guide post 124, which is used for the elastic member 43 to be sleeved, so as to prevent the elastic member 43 from being skewed during the extension process and affecting the test result of the force. The first guide post 124 is arranged in the first guide sleeve 123.

[0048] Specifically, see Figure 2 When the rotating lever 42 applies elastic force to the sensor 30, a protrusion 422 is provided on the rotating lever 42. In this way, when the elastic member 43 applies pressure to the rotating lever 42 to drive the rotating lever 42 to rotate, the protrusion 422 rotates to apply pressure to the sensor 30, so that the sensor 30 can receive the force signal.

[0049] It can be understood that in order to facilitate signal transmission between the hand dynamometer of this embodiment and an external display terminal, the circuit board 20 can transmit signals to the external display terminal via Bluetooth.

[0050] The above-mentioned handgrip dynamometer 100 is performed by pressing the upper shell 12 with the hand. The upper shell 12 receives the pressing force and presses the elastic member 43. The elastic member 43 drives the rotating lever 42 to rotate. The rotation of the rotating lever 42 applies pressing force to the sensor 30. The pressing force received by the sensor 30 is transmitted to the circuit board 20. Finally, the signal between the circuit board 20 and the external display terminal is transmitted, and the test result is displayed through the display terminal. In this way, the patient can get the test result with a smaller pressing force, which is convenient for patients in the recovery period to use.

[0051] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
