[0036] Reference below Figure 1-Figure 3 A needle-finding device 100 according to an embodiment of the present invention is described.

[0037] Combination Figure 1 and Figure 2 According to the needle-finding device 100 of the present invention, it includes: a first mounting bracket 110 and a second mounting bracket 120, the second mounting bracket 120 is rotatably mounted on the first mounting bracket 110 around a first axis; a magnetic member 130, the magnetic member 130 is arranged on the second mounting bracket 120, and is used to absorb the needle.

[0038] Specifically, the first mounting bracket 110 is used to provide a mounting position for the second mounting bracket 120 to facilitate the installation of the second mounting bracket 120, and the second mounting bracket 120 can rotate around the first axis relative to the first mounting bracket 110, so that the magnetic component 130 arranged on the second mounting bracket 120 can rotate around the first axis relative to the first mounting bracket 110, so as to adjust the position and angle of the magnetic component 130, so that the needle finding device 100 can adsorb needles in different positions, thereby improving the needle finding effect of the needle finding device 100, and after completing the needle finding, the second mounting bracket 120 can be flipped to drive the magnetic component 130 to flip, so as to facilitate the collection and processing of the needle.

[0039] In some examples, the needle finding device 100 also includes a driving assembly 140, which includes: a first driving unit 141, the first driving unit 141 is installed on the first mounting bracket 110; a second driving unit 144, the second driving unit 144 is installed on the second mounting bracket 120, and the first driving unit 141 is used to drive the second driving unit 144 to drive the second mounting bracket 120 to rotate around the first axis.

[0040] Specifically, the first driving part 141 can move relative to the first mounting bracket 110, and the first driving part 141 can drive the second driving part 144 to move. The second driving part 144 is installed on the second mounting bracket 120 and can be linked with the second mounting bracket 120, so that the first driving part 141 can drive the second mounting bracket 120 to rotate around the first axis through the second driving part 144, and the second mounting bracket 120 drives the magnetic part 130 to rotate around the first axis, so that the position and angle of the magnetic part 130 can be adjusted, which effectively improves the needle finding effect of the needle finding device 100. At the same time, it is convenient to observe the adsorption of the magnetic part 130 on the needle without turning the needle finding device 100 over as a whole, which effectively improves the convenience of use of the needle finding device 100.

[0041] According to the needle finding device 100 of the present invention, by setting a first mounting bracket 110 and a second mounting bracket 120, and allowing the second mounting bracket 120 to rotate relative to the first mounting bracket 110, the second mounting bracket 120 can drive the magnetic component 130 installed thereon to rotate, so as to adjust the position and rotation angle of the magnetic component 130, and improve the needle finding effect of the needle finding device 100. By setting a driving component 140, the user can drive the magnetic component 130 to rotate through the driving component 140 to adjust the position and rotation angle of the magnetic component 130, effectively improving the use convenience of the needle finding device 100, and at the same time facilitating the observation of the adsorption of the magnetic component 130 on the needle.

[0042] The magnetic member 130 may be configured as a permanent magnet.

[0043] Combination Figure 1 and Figure 2 In some embodiments of the utility model, the first driving part 141 includes a driving wheel 1411, the second driving part 144 is configured as a driven wheel, and the driving assembly 140 also includes a synchronous belt 142 mounted on the driving wheel 1411 and the driven wheel, and the driving wheel 1411 can drive the driven wheel to rotate through the synchronous belt 142; wherein the axis of the driving wheel 1411 is arranged parallel to the first axis, and the axis of the driven wheel is the first axis.

[0044] Specifically, the driving wheel 1411 can rotate relative to the first mounting bracket 110, the driven wheel is arranged on the second mounting bracket 120 and can be linked with the second mounting bracket 120, and the synchronous belt 142 is sleeved on the driving wheel 1411 and the driven wheel, so that when the driving wheel 1411 rotates, the driven wheel can be driven to rotate through the synchronous belt 142, so that the driving wheel 1411 can drive the second mounting bracket 120 to rotate, and the second mounting bracket 120 drives the magnetic part 130 to rotate.

[0045] It should be noted that the axis of the driving wheel 1411 is arranged in parallel with the axis of the driven wheel to ensure effective transmission between the driving wheel 1411 and the driven wheel.

[0046] Combination Figure 2 and Figure 3 In some embodiments of the utility model, the first driving part 141 also includes a driving handle 143, the first mounting bracket 110 is provided with a mounting groove 111, and the driving handle 143 includes: a rotating shaft 1431, the rotating shaft 1431 is installed in the mounting groove 111, and is coaxially arranged with the driving wheel 1411, the rotating shaft 1431 can rotate around the central axis of the rotating shaft 1431 in the mounting groove 111, and the rotating shaft 1431 can slide in the mounting groove 111 along the axial direction of the rotating shaft 1431.

[0047] It should be noted that the axis of the rotating shaft 1431 is parallel to the first axis.

[0048] Specifically, a mounting groove 111 is provided at the axial end of the first mounting bracket 110, and the rotating shaft 1431 of the driving handle 143 is embedded in the mounting groove 111 and can rotate in the mounting groove 111. The rotating shaft 1431 is coaxially arranged with the driving wheel 1411, that is, the central axis of the rotating shaft 1431 is the axis of the driving wheel 1411, and the rotating shaft 1431 can rotate coaxially with the driving wheel 1411.

[0049] The driving handle 143 also includes a driving arm 1432, which is connected to the rotating shaft 1431, and the driving arm 1432 is connected to the driving wheel 1411 through a synchronization rod 1434, so that the driving arm 1432 drives the driving wheel 1411 to rotate synchronously.

[0050] Specifically, one end of the rotating shaft 1431 extends out from the mounting groove 111, and the driving arm 1432 is connected to the end of the rotating shaft 1431 extending out from the mounting groove 111 and extends along the radial direction of the rotating shaft 1431. The driving arm 1432 is connected to the driving wheel 1411 through the synchronization rod 1434, and the synchronization rod 1434 is arranged parallel to the axis of the rotating shaft 1431. When the driving arm 1432 is rotated, the driving arm 1432 rotates relative to the first mounting bracket 110 through the rotating shaft 1431. At the same time, the driving arm 1432 can drive the driving wheel 1411 to rotate synchronously through the synchronization rod 1434, thereby realizing the driving of the driving wheel 1411. The driving wheel 1411 drives the driven wheel to rotate through the synchronous belt 142, and the driven wheel drives the second mounting bracket 120 to rotate, thereby adjusting the position and angle of the magnetic component 130.

[0051] At the same time, the driving arm 1432 can drive the rotating shaft 1431 to slide in the installation groove 111 along the axial direction.

[0052] like Figure 3 As shown, in some embodiments of the present invention, the synchronization rod 1434 includes a connecting rod 341 and a limiting portion 342. The connecting rod 341 is inserted into the driving wheel 1411 along an axial direction parallel to the rotating shaft 1431. At the same time, one axial end of the connecting rod 341 is connected to the driving arm 1432 so that the driving arm 1432 can drive the driving wheel 1411 to rotate.

[0053] Furthermore, the limiting portion 342 is arranged at one end of the connecting rod 341 away from the driving arm 1432, and the limiting portion 342 can cooperate with the outer wall surface of the driving wheel 1411 to prevent the driving arm 1432 from simultaneously driving the connecting rod 341 to separate from the driving wheel 1411 when the rotating shaft 1431 is driven by the driving arm 1432 to slide in the mounting groove 111, thereby ensuring the reliability of the connection between the driving handle 143 and the driving wheel 1411.

[0054] In some embodiments of the utility model, one of the first mounting bracket 110 and the driving arm 1432 is provided with a positioning protrusion 150, and the other of the first mounting bracket 110 and the driving arm 1432 is provided with a positioning groove 160; wherein the positioning protrusion 150 is protruding along the axial direction of the rotating shaft 1431, and is suitable for positioning and cooperating with the positioning groove 160 to lock the driving handle 143 with the first mounting bracket 110.

[0055] For example, refer to Figure 3The first mounting bracket 110 may be provided with a positioning protrusion 150 on a side opposite to the driving arm 1432. The positioning protrusion 150 may protrude from the first mounting bracket 110 along a direction parallel to the axis of the rotating shaft 1431 toward the driving arm 1432. A positioning groove 160 may be formed on the driving arm 1432. The positioning groove 160 is recessed on the driving arm 1432 along a direction parallel to the axis of the rotating shaft 1431 toward a direction away from the first mounting bracket 110. The positioning protrusion 150 may be embedded in the positioning groove 160. At this time, the driving handle 143 cannot rotate around the axis of the rotating shaft 1431 to achieve the locking of the driving handle 143 and the first mounting bracket 110. When the driving handle 143 needs to be rotated, the positioning protrusion 150 and the positioning groove 160 can be disengaged, thereby releasing the locking of the driving handle 143 and the first mounting bracket 110, and the driving handle 143 can be rotated around the rotation axis of the rotating shaft 1431.

[0056] Of course, it is understandable that a positioning groove 160 can be provided on the side of the first mounting bracket 110 opposite to the driving arm 1432, and a positioning protrusion 150 can be formed on the driving arm 1432. The positioning groove 160 of this structure has an extension direction opposite to that of the above-mentioned positioning groove 160. Similarly, the positioning protrusion 150 of this structure has an extension direction opposite to that of the above-mentioned positioning protrusion 150. However, the technical effects achieved by the two structures are the same, which will not be elaborated here one by one.

[0057] For the convenience of description, the following description is given by taking an example that the positioning protrusion 150 is disposed on the first mounting bracket 110 and the positioning groove 160 is disposed on the driving arm 1432 .

[0058] When it is necessary to lock the driving handle 143 with the first mounting bracket 110, the driving handle 143 can be pressed against and the rotating shaft 1431 slides in the mounting groove 111 toward the bottom of the mounting groove 111. At the same time, the driving handle 143 as a whole slides along an axial direction parallel to the rotating shaft 1431 toward the first mounting bracket 110. The positioning protrusion 150 can be embedded in the positioning groove 160 to lock the driving handle 143 in the circumferential direction. The driving handle 143 cannot continue to rotate, thereby realizing the positioning of the driving wheel 1411, and further making it impossible for the synchronous belt 142, the driven wheel and the second mounting bracket 120 to continue to rotate, thereby realizing the positioning of the magnetic component 130.

[0059] When the magnetic part 130 needs to be rotated, the driving handle 143 can be driven to move the entire part away from the first mounting bracket 110, and the positioning protrusion 150 can be disengaged from the positioning groove 160, thereby releasing the lock between the driving handle 143 and the first mounting bracket 110, and the driving handle 143 can rotate around the axis of the rotating shaft 1431 and drive the driving wheel 1411 to rotate, and the driving wheel 1411 drives the driven wheel to rotate through the synchronous belt 142, and the driven wheel drives the second mounting bracket 120 to rotate, and the second mounting bracket 120 drives the magnetic part 130 to rotate, thereby adjusting the position and angle of the magnetic part 130.

[0060] In some embodiments of the utility model, a plurality of positioning protrusions 150 can be formed on the first mounting bracket 110, and the plurality of positioning protrusions 150 are arranged at intervals and in a circular arrangement along the circumferential direction of the mounting groove 111. The positioning groove 160 can be positioned and cooperated with any one of the plurality of positioning protrusions 150, so that the driving handle 143 can be positioned at different angles. The driving handle 143 can position the driving wheel 1411 through the synchronization rod 1434, and the driving wheel 1411 can position the driven wheel and the second mounting bracket 120 through the synchronization belt 142, thereby realizing the positioning of the magnetic member 130 at different angles, facilitating the user to adjust the inclination angle of the magnetic member 130 according to the different positions of the needle device, facilitating the needle finding and needle suction operations in the corners or other dead corners, effectively improving the practicality of the needle finding device 100, and facilitating user operation.

[0061] Combination Figure 1 and Figure 2 In some embodiments of the utility model, the second mounting bracket 120 includes: a rotating bracket body 121, and the magnetic member 130 is arranged on the rotating bracket body 121; the mounting shaft 122, the mounting shaft 122 is arranged on the rotating bracket body 121, and the rotating bracket body 121 is rotatably connected to the first mounting bracket 110 through the mounting shaft 122, and the driven wheel sleeve is arranged on the mounting shaft 122, and is suitable for driving the mounting shaft 122 to rotate synchronously.

[0062] Specifically, the rotating bracket body 121 is used to provide a mounting position for the magnetic component 130 to facilitate the installation of the magnetic component 130. The rotating bracket body 121 is rotatably mounted on the first mounting bracket 110 through the mounting shaft 122. The driven wheel is sleeved on the mounting shaft 122 and is coaxially arranged with the mounting shaft 122. The driven wheel can be fixedly connected to the mounting shaft 122. When the driving wheel 1411 drives the driven wheel to rotate through the synchronous belt 142, the driven wheel can drive the mounting shaft 122 to rotate around the first axis. The mounting shaft 122 drives the rotating bracket body 121 to rotate relative to the first mounting bracket 110, thereby allowing the magnetic component 130 to rotate relative to the first mounting bracket 110.

[0063] like Figure 2 As shown, in some embodiments of the present invention, the rotating bracket body 121 includes: two side plates 1211, which are spaced apart and relatively arranged along the axial direction of the first axis; and a mounting plate 1212, which is connected between the two side plates 1211 and is used to install the magnetic part 130.

[0064] Specifically, the mounting plate 1212 is supported between the two side plates 1211 along the direction of the first axis and connected to the two side plates 1211 to ensure the stability between the two side plates 1211 and the mounting plate 1212. The mounting plate 1212 can be constructed as a rectangular plate body, and the magnetic component 130 can be installed on a side wall of the mounting plate 1212 with a larger area to increase the connection area between the magnetic component 130 and the mounting plate 1212, which is beneficial to improve the assembly reliability of the magnetic component 130.

[0065] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the mounting shaft 122 is respectively passed through the two side plates 1211 along the axial direction of the first axis, and is rotatably connected to the first mounting bracket 110, and the driven wheel is installed on the mounting shaft 122 passing through the side plate 1211.

[0066] Specifically, the mounting shaft 122 and the mounting plate 1212 are spaced apart in a direction perpendicular to the first axis, and the mounting shaft 122 extends along the direction of the first axis and passes through the two side plates 1211. The mounting shaft 122 is rotatably connected to the first mounting bracket 110. For example, a groove structure can be formed on the wall surface of the first mounting bracket 110 opposite to the two side plates 1211. The mounting shaft 122 can be plugged into the groove structure after passing through the two side plates 1211, and the mounting shaft 122 can rotate in the groove structure, so that the mounting shaft 122 is rotatably connected to the first mounting bracket 110. The driven wheel is sleeved on the part of the mounting shaft 122 passing through the side plate 1211 and is located between the side plate 1211 and the first mounting plate 1212. The driven wheel can drive the rotating bracket body 121 to rotate relative to the first mounting bracket 110.

[0067] It should be noted that “the extension direction of the first axis” can also be understood as the left-right direction of the needle-finding device 100 .

[0068] Combination Figure 1 and Figure 2In some embodiments of the utility model, at least one end of the mounting shaft 122 can be further passed through the first mounting bracket 110 and extend from the first mounting bracket 110, and the driven wheel can be sleeved on the portion of the mounting shaft 122 extending from the first mounting bracket 110 to facilitate the installation of the driven wheel; the mounting shaft 122 can pass through the first mounting bracket 110 at one end and be plugged into the first mounting bracket 110 at the other end; or the mounting shaft 122 can pass through the first mounting bracket 110 at both ends, and the driven wheel can be sleeved on one end of the mounting shaft 122 that is opposite to the driving wheel 1411.

[0069] It is understandable that the matching mode of the installation shaft 122 and the side plate 1211 can be determined according to actual production requirements and is not specifically limited here, as long as the installation shaft 122 can rotate relative to the first installation bracket 110.

[0070] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the first mounting bracket 110 includes: a mounting bracket body 112, the mounting bracket body 112 is formed with a mounting area 113, and the second mounting bracket 120 is installed in the mounting area 113; a joystick 114, the joystick 114 is connected to the mounting bracket body 112 and is used for the user to hold, and the first driving part 141 is installed on the joystick 114.

[0071] Specifically, an open mounting area 113 is formed on the front side of the mounting bracket body 112, the second mounting bracket 120 is arranged in the mounting area 113 and is connected to the mounting bracket body 112 through a mounting shaft 122, and the joystick 114 is arranged on the side of the mounting bracket body 112 away from the mounting area 113 (i.e., the rear side of the mounting area 113), so that the joystick 114 can avoid the second mounting bracket 120 to prevent the joystick 114 from interfering with the rotation of the second mounting bracket 120.
