[0034] like Figures 1 to 4As shown, this embodiment provides a housing structure for a guide rail gauge, which includes a cover body 1, a button 2, and a window assembly 3. The cover body 1 has an opening 11 on one side, and a window opening 12 and a button opening 13 on its top surface. The button 2 is disposed inside the cover body 1. The window assembly 3 has a first positioning member 4, which is used to connect with a positioning fixture 100 of an ultrasonic welding device. The opening 11 allows the positioning fixture 100 to enter the cover body 1, and positions the window assembly 3 at the window opening 12. The window assembly 3 is welded to the cover body 1. The button 2 is sandwiched between the window assembly 3 and the cover body 1, and one end of the button 2 passes through the button opening 13.

[0035] The guide rail meter housing structure provided in this embodiment has an opening 11 on the side of the cover body 1, and a viewing window opening 12 and a button opening 13 on the top surface. The viewing window assembly 3 and the button 2 need to enter the cover body 1 through the opening 11 and be fixed to the cover body 1. In order to facilitate the welding head of the ultrasonic welding device to extend into the cover body 1 from the side of the cover body 1 and to accurately weld the viewing window assembly 3 to the cover body 1, a first positioning member 4 is provided on the viewing window assembly 3. The first positioning member 4 is connected to the positioning fixture 100 of the ultrasonic welding device. Next, the window assembly 3 is positioned on the positioning fixture 100, the button 2 is placed on the window assembly 3, and then the cover body 1 is placed over the outside of the window assembly 3 and the positioning fixture 100. Ultrasonic welding can be achieved, and the position of the window assembly 3 relative to the cover body 1 will not change during the welding process, which improves the welding quality, ensures that the window assembly 3 can be placed at the window opening 12, and at the same time, the button 2 can be fixed between the window assembly 3 and the cover body 1, and one end of the button 2 passes through the button opening 13, which improves the yield.

[0036] In some embodiments, multiple first positioning members 4 are provided, and the multiple first positioning members 4 are spaced apart to provide uniform support force for the positioning fixture 100 supporting the window assembly 3.

[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the window assembly 3 includes a window plate 31 and a window 32 connected to the window plate 31. The window plate 31 is welded to the cover body 1, and the window 32 is positioned at the window opening 12. The first positioning member 4 includes one of a positioning hole and a positioning post provided on the window plate 31, and the positioning fixture 100 is provided with the other of a positioning hole and a positioning post, and the positioning post can be inserted into the positioning hole. The positioning connection structure between the window assembly 3 and the positioning fixture 100 is simple and easy to install and disassemble. Optionally, in order to prevent the window assembly 3 from affecting the installation of other components inside the cover body 1, the first positioning member 4 includes a positioning hole provided on the window plate 31, which does not occupy space inside the cover body 1.

[0038] Optionally, the viewing window 31 is further provided with a button mounting part 33, which is used to position the button 2 on the viewing window 31. The first positioning member 4 is disposed between the viewing window 31 and the button mounting part 33. The button mounting part 33 can position the relative position of the button 2 and the viewing window 31. After the viewing window 31 is welded to the cover body 1, the button 2 can be fixedly installed, simplifying the assembly process.

[0039] The button mounting part 33 includes a button mounting groove 331 disposed on the window plate 31. The bottom of the button mounting groove 331 is provided with a through hole 332. The button 2 is placed in the button mounting groove 331, and the wiring terminal of the button 2 is correspondingly disposed with the through hole 332. The cover body 1 is provided with a circuit board. The wires used to connect the button 2 and the circuit board are connected to the button 2 after passing through the through hole 332. The button mounting groove 331 can position the button 2 and prevent the button 2 from moving on the window plate 31, which would affect the soldering of the window plate 31.

[0040] To prevent dust and other impurities from entering the cover body 1 through the button opening 13, the gap between the button opening 13 and the button 2 needs to be sealed after the window assembly 3 and the button 2 are installed inside the cover body 1. Optionally, a first sealing element 333 is provided circumferentially along the opening of the button mounting groove 331. The first sealing element 333 abuts against the inner wall of the cover body 1, which can effectively prevent dust and other impurities from entering the cover body 1 through the button opening 13 without affecting the external aesthetics of the cover body 1. The first sealing element 333 can be made of rubber or silicone, and no specific limitation is made here. The sealing of the button opening 13 is achieved at the same time as welding the window assembly 3 to the cover body 1.

[0041] Optionally, the viewing window plate 31 has a viewing hole, and a viewing window 32 covers the viewing hole. The viewing window 32 protrudes from the viewing window plate 31, and a second sealing element 34 is provided at the connection between the viewing window 32 and the viewing window plate 31. The second sealing element 34 abuts against the inner wall of the cover body 1. The viewing window 32 is transparent, allowing observation of the working status inside the guide rail gauge. The viewing window 32 protrudes from the viewing window plate 31, and when the viewing window plate 31 is connected to the cover body 1, the viewing window 32 can pass through the viewing window opening 12 and be positioned on the outside of the cover body 1. To prevent external dust and other impurities from entering the cover body 1 through the viewing window opening 12, a second sealing element 34 is provided at the connection between the viewing window 32 and the viewing window plate 31. The viewing window opening 12 is sealed simultaneously with the welding of the viewing window plate 31 to the cover body 1, without affecting the external aesthetics of the cover body 1. The second sealing element 34 can be made of rubber or silicone, and no specific limitation is made here.

[0042] The outer casing structure of the guide rail also includes a cover plate (not shown in the figure). A first step structure 14 is provided circumferentially at the opening 11 of the cover body 1, and a second step structure is provided circumferentially on one side of the cover plate. The cover plate is placed over the opening 11, and the second step structure is coupled to the first step structure 14, which improves the sealing performance of the connection between the cover plate and the cover body 1.

[0043] Continue to refer to Figure 3 and Figure 4 As shown, the bottom surface of the cover body 1 is recessed with a guide rail groove 15 on the inner side of the cover body 1 to facilitate the fixed installation of the guide rail on the guide rail. The guide rail groove 15 does not affect the positioning fixture 100 being placed inside the cover body 1. That is to say, it is precisely because the first positioning element 4 is set on the window assembly 3 that the window assembly 3 is first positioned on the positioning fixture 100, so that the cover body 1 can be placed on the outside of the positioning fixture 100 without being affected by the guide rail groove 15, thus ensuring the normal welding of the ultrasonic welding device.

[0044] This embodiment also provides a guide rail gauge, including the housing structure of the guide rail gauge described above. The guide rail gauge also includes other components such as a circuit board, which are prior art and will not be described in detail here.
