[0030] Reference Figures 1 to 5 An auxiliary screw locking positioning jig comprises a base 1, a cover plate 2 and guide pipes 3. The base 1 is fixed with the cover plate 2 through support columns 15. A plurality of guide pipes 3 are installed on the cover plate 2. The guide pipes 3 are vertically arranged between the cover plate 2 and the base 1. The material opening 31 at the upper end of the guide pipe 3 leaks out of the upper side of the cover plate 2. The butt joint 32 at the lower end of the guide pipe 3 has a gap between the base 1. The base 1 and the cover plate 2 butt joint the product shell 6 through a positioning structure. When the product shell 6 and the product circuit board 7 are placed on the base 1, the guide pipe 3 extends into the product shell 6. The butt joint 32 at the lower end of the guide pipe 3 leads to the mounting hole 71 of the product circuit board 7. The lumen of the guide pipe 3 forms a channel for guiding the screw 8 and the screwdriver, so as to limit the screw 8 to be vertically installed between the mounting hole 71 of the product circuit board 7 and the product shell 6.

[0031] The auxiliary screw locking positioning jig of the present application butt joints the product shell 6 through the positioning structure between the base 1 and the cover plate 2, so that the butt joint 32 of the guide pipe 3 can be aligned with the mounting hole 71 of the product circuit board 7. The inner diameter of the lumen of the guide pipe 3 is larger than the size of the screw 8. The screw 8 and the screwdriver are guided through the lumen of the guide pipe 3, so as to ensure that the screw 8 can be vertically installed in the mounting hole 71. The cover plate 2 is located above the product shell 6, so as to protect the product shell 6 and the product circuit board 7, avoid the falling of the moving screw 8 on the product circuit board 7, and damage the electronic components on the product circuit board 7.

[0032] In order to butt joint the product shell 6, in the embodiment, referring to Figures 1 to 5 The upper end surface of the base 1 is provided with a first positioning strip 11, a second positioning strip 12, a third positioning strip 13 and a fourth positioning strip 14.

The position between the cover plate 2 and the base 1 is fixed. After the base 1 is docked with the product shell 6, the cover plate 2 is buckled to the base 1 to accurately dock with the product shell 6. The first positioning block 51 and the second positioning block 52 form an L-shaped second limit, which can prevent the upper end of the product shell 6 from shaking and further ensure that the product shell 6 is stably positioned between the base 1 and the cover plate 2.

[0034] In order to facilitate the taking and placing of the product shell 6, in the embodiment, with reference to Figure 3 , the first positioning strip 11 and the third positioning strip 13 are arranged along the length direction of the base 1, the second positioning strip 12 and the third positioning strip 13 are arranged along the width direction of the base 1, and the thicknesses of the third positioning strip 13 and the fourth positioning strip 14 are smaller than the thicknesses of the first positioning strip 11 and the second positioning strip 12.

[0035] It can be understood that, in this way, when the product shell 6 is placed on the base 1, the lower third positioning strip 13 and the fourth positioning strip 14 can facilitate the product shell 6 to enter and exit the first limit, and the higher first positioning strip 11 and the second positioning strip 12 can block the product shell 6, so that the product shell 6 falls into the first limit.

[0036] In order to install the first positioning block 51 and the second positioning block 52, in the embodiment, with reference to Figure 4 and Figure 5 , the first positioning block 51 is arranged along the length direction of the cover plate 2, the cover plate 2 is provided with a first long circular hole 21 along the width direction, and the first long circular hole 21 is provided with a first screw 53 connected with the first positioning block 51; the second positioning block 52 is arranged along the width direction of the cover plate 2, the cover plate 2 is provided with a second long circular hole 22 along the length direction, and the second long circular hole 22 is provided with a second screw 54 connected with the second positioning block 52.

[0037] It can be understood that, in this way, the first positioning block 51 and the second positioning block 52 are installed on the cover plate 2 through the first screw 53 and the second screw 54, and the positions of the first screw 53 and the second screw 54 are adjusted through the first long circular hole 21 and the second long circular hole 22 on the cover plate 2, so that the positions of the first positioning block 51 and the second positioning block 52 are adjusted according to the size of the cover plate 2, and the cover plate 2 can be stably docked with the product shell 6.

[0038] In order to stably connect the cover plate 2 and the base 1, in the embodiment, with reference to Figure 1and Figure 2 Four support columns 15 are fixed at the four corners of the base 1. A positioning head 16 is provided at the upper end of the support column 15. Positioning holes 23 are provided at the four corners of the cover plate 2. The support column 15 is inserted into the positioning hole 23 through the positioning head 16.

[0039] Understandably, with this setup, the four support columns 15 on the base 1 support the cover plate 2, and the cover plate 2 is positioned by the positioning head 16 and the positioning hole 23 of the cover plate 2, ensuring that the cover plate 2 is stably installed on the base 1.

[0040] To improve the compatibility of catheter 3, in this embodiment, reference is made to... Figure 4 The conduit 3 includes a first connecting pipe 33 and a second connecting pipe 34. The first connecting pipe 33 is provided with external threads, and the second connecting pipe 34 is provided with internal threads. The second connecting pipe 34 is sleeved on the lower end of the first connecting pipe 33 through the external and internal threads. The first connecting pipe 33 is connected to the cover plate 2, and the second connecting pipe 34 is located on the side near the base 1.

[0041] Understandably, with this setup, the first connecting pipe 33 is connected to the cover plate 2, and the second connecting pipe 34 is fitted under the first connecting pipe 33. Depending on the installation height of different product housings 6 and product circuit boards 7, different lengths of the second connecting pipe 34 can be selected. The second connecting pipe 34 is quickly installed on the first connecting pipe 33 through threads, so that the conduit 3 can be compatible with the installation requirements of different installation heights.

[0042] In order to install conduit 3, in this embodiment, refer to Figure 4 and Figure 5 A fixing hole 24 is provided in the center of the cover plate 2, and the first connecting pipe 33 of the conduit 3 is installed in the fixing hole 24.

[0043] Understandably, with this setup, the position of the fixing hole 24 is fixed. When the product circuit board 7 needs to install the screw 8 at the corresponding position of the fixing hole 24, the second connecting tube 34 can be put on the lower end of the first connecting tube 33. If the product circuit board 7 does not need to install the screw 8 at the corresponding position of the fixing hole 24, the second connecting tube 34 needs to be removed to prevent the second connecting tube 34 from hitting the electronic components on the product circuit board 7.

[0044] To improve the overall compatibility of the fixture, in this embodiment, reference is made to... Figure 4 The cover plate 2 is provided with a first adjustment hole 25 in the shape of "I" and a second adjustment hole 26 in the shape of "L". The first adjustment hole 25 is set along the length direction of the cover plate 2, and the second adjustment hole 26 is set along the length and width directions of the cover plate 2. The first adjustment hole 25 and the second adjustment hole 26 are connected to the guide tube 3 through the limiting component 4.

[0045] It can be understood that, thus, according to the mounting hole 71 position of the product circuit board 7 and product shell 6 of different sizes, the conduit 3 is adjusted to be opposite to the mounting hole 71 through the first adjusting hole 25 and the second adjusting hole 26, so that the conduit 3 can accurately guide the screw 8 and the screwdriver to travel into the mounting hole 71, thereby improving the compatibility of the whole jig. The conduit 3 in the adjusted position is locked by the limiting assembly 4, so that the conduit 3 cannot move in the first adjusting hole 25 and the second adjusting hole 26 by itself.

[0046] In order to facilitate the adjustment of the position of the conduit 3, in the embodiment, the limiting assembly 4 includes a first nut 41, a first blocking piece 42, a second blocking piece 43 and a second nut 44 which are sequentially sleeved on the first connecting pipe 33.

The first blocking piece 42 is located between the first nut 41 and the upper end surface of the cover plate 2, and the second blocking piece 43 is located between the second nut 44 and the lower end surface of the cover plate 2, so as to limit the first connecting pipe 33 in the first adjusting hole 25 or the second adjusting hole 26. Figure 4 Figure 5

[0047] It can be understood that, thus, the limiting assembly 4 locks the first connecting pipe 33 through the first nut 41 and the second nut 44 located on the upper and lower sides of the cover plate 2. When the position of the conduit 3 needs to be adjusted, the first nut 41 or the second nut 44 is loosened, so that the first connecting pipe 33 can move along the first adjusting hole 25 or the second adjusting hole 26. After the position is adjusted, the first nut 41 or the second nut 44 is tightened, so that the conduit 3 can be locked. Through the limiting of the first blocking piece 42 and the second blocking piece, the first connecting pipe 33 can be vertically arranged in the first adjusting hole 25 or the second adjusting hole 26. The limiting assembly 4 is only connected with the first connecting pipe 33. The first connecting pipe 33 is locked in the first adjusting hole 25 or the second adjusting hole 26 through the limiting assembly 4. Whether the second connecting pipe 34 needs to be sleeved under the corresponding first connecting pipe 33 can be flexibly selected according to the position of the mounting hole 71, so as to avoid that the redundant second connecting pipe 34 bumps the electronic components on the product circuit board 7.

[0048] In order to facilitate the determination of whether the conduit 3 is aligned with the mounting hole 71, in the embodiment, the cover plate 2 is a transparent acrylic cover plate 2.

[0049] It can be understood that, thus, the transparent cover plate 2 can observe the positional relationship between the conduit 3 and the product circuit board 7 in real time, so that whether the docking port 32 of the conduit 3 is aligned with the mounting hole 71 of the product circuit board 7 can be observed very conveniently, so that the conduit 3 can accurately guide the screw 8 and the screwdriver to travel into the mounting hole 71. The acrylic cover plate 2 is relatively hard, so that the product shell 6 and the product circuit board 7 can be well protected.

[0050] ​​The embodiment of the application is used for assembling uninterrupted power supply, the product shell 6 is butted by the positioning structure between the base 1 and the cover plate 2, so that the butt joint 32 of the conduit 3 can be aligned with the mounting hole 71 of the product circuit board 7, the screw 8 and the screwdriver are guided through the lumen of the conduit 3, the screw 8 is prevented from being inclined, and it is ensured that the screw 8 can be vertically installed in the mounting hole 71; the position of the conduit 3 on the cover plate 2 is adjusted according to the position of different mounting holes 71, and is locked through the limiting assembly 4, and the compatibility of the jig is improved; the cover plate 2 is located above the product shell 6, the product shell 6 and the product circuit board 7 can be protected, the falling of the moving screw 8 on the product circuit board 7 is avoided, and the electronic components on the product circuit board 7 are prevented from being damaged.
