[0052] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0053] Example

[0054] Figure 1 This is a structural schematic diagram of a connection strength detection mechanism 100 in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the connection strength detection mechanism 100 in the illustrated embodiment.

[0055] See also Figure 1 and Figure 2 An embodiment of the present application provides a connection strength detection mechanism 100 , including a housing 10 , a pressing member 20 , a mating portion 30 , an elastic member 40 and an indicating assembly 60 .

[0056] The housing 10 has a first end 10a and a second end 10b opposite to each other along a first direction A. The housing 10 is provided with a first hole 11, which extends along the first direction A and passes through the first end 10a to form a first opening 12 located at the first end 10a. The housing 10 is provided with a first limiting portion 131 and a second limiting portion 132, respectively, which are spaced a predetermined distance L apart from each other along the first direction A. The housing 10 is made of insulating material. The pressing member 20 is movably matched with the first hole 11 along the first direction A and can extend from the first opening 12. The matching portion 30 is connected to the pressing member 20. The matching portion 30 can move between the first limiting portion 131 and the second limiting portion 132 along the first direction A driven by the pressing member 20. The first limiting portion 131 can contact the side of the matching portion 30 close to the first opening 12 along the first direction A, and the second limiting portion 132 can contact the side of the matching portion 30 away from the first opening 12 along the first direction A. The material of the matching portion 30 is a conductive material. The elastic member 40 is disposed in the first channel 11 and elastically presses against the pressing member 20 to apply an elastic restoring force along the first direction A to the pressing member 20.

[0057] The indicating component 60 includes a conductive member 61, a wire 62, a battery 63 and an indicating member 64. The conductive member 61 is connected to the second position-limiting portion 132, one end of the wire 62 is electrically connected to the conductive member 61, and the other end of the wire 62 is electrically connected to the matching portion 30. The battery 63 and the indicating member 64 are respectively connected to the wire 62. The conductive member 61 can contact the matching portion 30 when the matching portion 30 reaches the second position-limiting portion 132, so that the indicating component 60 forms a loop, thereby triggering the indicating member 64 to send an indicating signal.

[0058] In the above connection strength detection mechanism 100, one end of the pressing member 20 extending from the first opening 12 is used to press the member to be detected (not shown in the figure) to apply a pressing detection force to the member to be detected, so as to determine whether the connection strength of the member to be detected meets the standard by checking whether the member to be detected is intact after the pressing detection force is applied. The first limiting portion 131 and the second limiting portion 132 are spaced a predetermined distance L along the first direction A to limit the displacement of the matching portion 30 and the pressing member 20 along the first direction A, thereby limiting the compression amount of the elastic member 40 along the first direction A, that is, limiting the elastic restoring force along the first direction A applied by the elastic member 40 to the pressing member 20. When in use, the elastic restoring force along the first direction A applied by the elastic member 40 to the pressing member 20 is used as the pressing detection force. When the mating portion 30 reaches the second limit portion 132, the mating portion 30 contacts the conductive member 61, and the indicator member 64 sends an indication signal to prompt to stop applying the pressing detection force to the part to be detected, thereby avoiding the scrapping of the part to be detected due to excessive pressing detection force. This is beneficial to reducing the scrap rate of the part to be detected during the connection strength detection process, and avoiding missing detection of the part to be detected whose connection strength does not meet the standard due to too small pressing detection force.

[0059] Optionally, the connection strength detection mechanism 100 can be used to detect the welding strength of the parts to be detected, and can also be used to detect the connection strength of the parts to be detected using other connection methods.

[0060] Optionally, the part to be tested may be a machined part, a stamped part or a MIM (Metal Powder Injection Molding Technology) part.

[0061] It should be noted that the predetermined distance L and the elastic coefficient of the elastic member 40 can be set according to the detection requirements of the part to be detected, so that the connection strength detection mechanism 100 can be applicable to different parts to be detected. The detection requirements can refer to the size of the pressing detection force required to check whether the connection strength of the part to be detected meets the standard.

[0062] Alternatively, if Figure 2 As shown, when the matching portion 30 contacts the first limiting portion 131, the elastic member 40 is constructed to be in a natural state. In this way, when the matching portion 30 moves from contacting the first limiting portion 131 to abutting the second limiting portion 132, the displacement of the matching portion 30 along the first direction A is equal to the compression amount of the elastic member 40 along the first direction A, so as to select the model of the elastic member 40 and set the size of the limiting groove 14 along the first direction A according to the detection needs of the part to be detected. Specifically, assuming that the size of the portion of the matching portion 30 located between the first limiting portion 131 and the second limiting portion 132 along the first direction A is R, then when the matching portion 30 abuts against the second limiting portion 132, the compression amount of the elastic member 40 along the first direction A is x=LR. Assuming that the elastic coefficient of the elastic member 40 is k, then when the matching portion 30 abuts against the second limiting portion 132, the elastic restoring force applied by the elastic member 40 to the pressing member 20 is F=kx.

[0063] In one embodiment, the elastic coefficient of the elastic member 40 is 0.6 kgf / mm. When the mating portion 30 reaches the second limiting portion 132, the compression amount of the elastic member 40 along the first direction A is 5 mm, and the elastic restoring force applied by the elastic member 40 to the pressing member 20 is 3 kgf.

[0064] In other embodiments, the elastic coefficient of the elastic member 40 and the compression amount of the elastic member 40 along the first direction A when the matching portion 30 reaches the second limiting portion 132 can be configured in other ways according to detection requirements and are not limited here.

[0065] In some embodiments, Figure 1 and Figure 2As shown, the indicator 64 is an indicator light 641. In this way, when the matching portion 30 is in contact with the conductive member 61, the indicator light 641 lights up to prompt to stop applying the pressing detection force to the part to be detected. When in use, when the indicator light 641 lights up, stop pushing the housing 10 toward the part to be detected along the first direction A, and separate the connection strength detection mechanism 100 from the part to be detected to check whether the part to be detected is intact. If it is intact, it is determined that the connection strength of the part to be detected meets the standard. If the part to be detected is damaged, it is determined that the connection strength of the part to be detected does not meet the standard.

[0066] In some embodiments, Figure 2 As shown, the housing 10 is provided with a second hole 15, which extends along the first direction A and passes through the second end 10b to form a second opening 16 located at the second end 10b, and an end of the second hole 15 away from the second opening 16 is connected to an end of the first hole 11 away from the first opening 12, and the indicator light 641 is provided in the second opening 16. In this way, the indicator light 641 is exposed from the second opening 16, so that it is easy to observe whether the indicator light 641 is on.

[0067] Figure 3 for Figure 1 A schematic structural diagram of the housing 10 in the illustrated embodiment.

[0068] In some embodiments, Figure 2 and Figure 3 As shown, a limiting groove 14 is provided on the housing 10, and the limiting groove 14 extends along the first direction A. The limiting groove 14 is connected to the first channel 11 and penetrates the housing 10 along the radial direction of the first channel 11. The groove wall of the limiting groove 14 on the side close to the first opening 12 along the first direction A forms a first limiting portion 131, and the groove wall of the limiting groove 14 on the side away from the first opening 12 along the first direction A forms a second limiting portion 132. The matching portion 30 at least partially extends into the limiting groove 14, and can move in the limiting groove 14 along the first direction A driven by the pressing member 20. One end of the conductive member 61 extends into the limiting groove 14 and is connected to the second limiting portion 132, and the other end of the conductive member 61 extends out of the housing 10. The wire 62 includes a first wire 621 and a second wire 622. The first wire 621 is located outside the housing 10. One end of the first wire 621 is electrically connected to the portion of the conductive member 61 located outside the housing 10, and the other end of the first wire 621 is electrically connected to the indicator light 641. The second wire 622 is passed through the first hole 11 and the second hole 15. One end of the second wire 622 is electrically connected to the indicator light 641, and the other end of the second wire 622 is electrically connected to the matching portion 30. The battery 63 is connected to the second wire 622. In this way, the first wire 621 and the second wire 622 are easily arranged.

[0069] In some embodiments, Figure 2As shown, the elastic member 40 is a coil spring, and the second wire 622 passes through the coil spring to make the structure of the connection strength detection mechanism 100 more compact.

[0070] In some embodiments, Figure 2 As shown, the matching portion 30 includes a plurality of matching portions 30, and the plurality of matching portions 30 are arranged at intervals along the circumference of the first channel 11. The plurality of limiting grooves 14 are arranged one-to-one corresponding to the plurality of matching portions 30. In this way, the plurality of matching portions 30 are arranged to improve the stability of the matching portions 30 and the pressing member 20 moving relative to the housing 10 along the first direction A.

[0071] In some embodiments, Figure 2 As shown, there are two matching parts 30. The connection strength detection mechanism 100 also includes a matching piece 50, which is inserted into the pressing piece 20 along the radial direction of the first hole 11. The matching piece 50 extends out of the pressing piece 20 at two opposite ends along the radial direction of the first hole 11, and forms a matching part 30 respectively. In this way, the matching piece 50 and the pressing piece 20 are easy to process and assemble.

[0072] In some embodiments, the conductive member 61 is a conductive connecting sheet, such as a steel sheet.

[0073] Optionally, the shell 10 may be made of plastic steel.

[0074] In some embodiments, Figure 2 As shown, the pressing member 20 includes a first cylinder 21 and a second cylinder 22. The first cylinder 21 is movably matched with the first channel 11 along the first direction A, and the matching portion 30 is connected to the first cylinder 21. One end of the second cylinder 22 is connected to the end of the first cylinder 21 away from the second end 10b along the first direction A, and the other end of the second cylinder 22 can extend from the first opening 12, and the radial dimension of the second cylinder 22 is smaller than the radial dimension of the first cylinder 21. In this way, it is convenient to set the radial dimension of the second cylinder 22 according to the size of the part to be detected. For example, the radial dimension of the second cylinder 22 can be made smaller than the size of the part to be detected, so as to facilitate the second cylinder 22 to directly contact the part to be detected during the connection strength detection process, and avoid the second cylinder 22 interfering with other parts outside the part to be detected.

[0075] In some embodiments, Figure 2 As shown, the connection strength detection mechanism 100 further includes a stopper 70, which is disposed in the first channel 11 and is located on a side of the pressing member 20 away from the first opening 12 along the first direction A. The elastic member 40 elastically abuts between the stopper 70 and the pressing member 20. In this way, by providing the stopper 70, one end of the elastic member 40 away from the pressing member 20 is fixed relative to the housing 10.

[0076] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
