Description

Technical Field

[0001] The utility model belongs to the technical field of lamp fixing, in particular to an adjusting nut for lamp fixing. Background Art

[0002] With the continuous development of the automotive industry, the design of lamp parts is becoming increasingly complex. In pursuit of a stylish exterior, new energy vehicles often design through or semi-through lamps, with lamps that are more than one meter long. As described in patent publication number CN216742374U, conventional lamp designs all use the traditional lamp fixing method of adjusting screws. The outer wall of the adjusting screw is partially formed with external threads. The end of the screw away from the nut is a smooth rod. The end of the smooth rod is a screw head that serves as a guide. The adjusting screw is then connected to the mounting nut for quick installation.

[0003] Under current technology, the space required for adjusting screws to extend into the sheet metal requires space for external thread tightening, nut tightening, and the space between the polished rod and the screw head. This significantly impacts the sheet metal depth during vehicle design. With increasing consumer demand for trunk space and automakers' demand for sheet metal and spoiler molding around the exterior edges of the vehicle, automotive designers are eager to reduce the depth required for lamps and sheet metal assembly when designing the exterior edges of the vehicle. This necessitates an adjusting nut to address this issue. Utility Model Content

[0004] In order to solve the technical problem of limited installation space in sheet metal parts in lamp fixing in the background art, the purpose of the present utility model is to provide an adjusting nut for lamp fixing, which can solve the above technical problem.

[0005] The technical solution to achieve the purpose of the utility model is: an adjusting nut for fixing a lamp, comprising a guide fixing plate, a pressure plate and a connecting rod, the connecting rod being located between the guide fixing plate and the pressure plate, and a through threaded hole being provided inside the guide fixing plate, the pressure plate and the connecting rod; the cross-sectional areas of the guide fixing plate and the pressure plate are both larger than the cross-sectional area of ​​the connecting rod, and a slot for fixing the lamp is formed between the top wall of the guide fixing plate, the side walls of the connecting rod and the bottom wall of the pressure plate.

[0006] In this solution, an adjusting nut is used to secure the lamp. Specifically, the adjusting nut secures the lamp within the groove formed between the top wall of the guide fixing plate, the side wall of the connecting rod, and the bottom wall of the pressure plate. A bolt is then passed through the mounting hole on the sheet metal and screwed into the threaded hole to secure the lamp to the sheet metal. Due to the presence of the adjusting nut, the length of the adjusting bolt's screw only needs to be sufficient to be screwed into the threaded hole. The length of the bolt within the sheet metal is limited to the height of the bolt cap, thus saving a significant amount of installation space. This solves the problem of traditional adjusting bolts requiring the entire screw to be inserted into the sheet metal, which occupies a significant amount of installation space within the sheet metal. Furthermore, the adjusting nut has a simple structure and is easy to install. If a fixing hole is provided on the lamp, the connecting rod only needs to be inserted into the fixing hole on the lamp.

[0007] Furthermore, the lamp has a slide groove and a guide groove. The diameter of the guide groove is larger than the diameter of the slide groove, and the slide groove is clamped in the clamping groove. The height of the slide groove is less than the length of the connecting rod. The slide groove is similar to a fixing hole, and the adjusting nut is fixed by the cooperation between the connecting rod and the slide groove. Specifically, during installation, the connecting rod can slide into the slide groove through the guide limit of the guide groove, and then be tightened by the adjusting screw. Since the height of the slide groove is less than the length of the connecting rod, the connecting rod can move within the slide groove and be adaptively adjusted according to the appropriate position of the adjusting nut on the lamp. The connection structure is stable and has a good tightening effect. It is convenient for adjusting and moving the lamp during use, and it is practical and simple in structure.

[0008] Furthermore, the guide fixing plate, the pressure plate, and the connecting rod are coaxially arranged and integrally formed; the chute and one side of the chute are respectively opened, and the connecting rod is inserted into the chute through the opening. Since the chute is clamped in the clamping groove, the diameter of the connecting rod is smaller than the diameter of the chute, and the cross-sectional areas of the guide fixing plate and the pressure plate are larger than the chute. Moreover, the guide fixing plate, the pressure plate, and the connecting rod are integrally formed. Therefore, when the connecting rod slides into the chute, an opening on one side of the chute is required, so that the connecting rod can slide into the chute, that is, the chute is completely clamped in the clamping groove.

[0009] Furthermore, the guide fixing plate is a polygonal structure, and the corners are arc guide surfaces. Compared with the circular ring shape, the guide fixing plate with a polygonal structure can reduce the space occupied in the lamp, and has the installation and fixing effect of being clamped in the lamp (in the guide groove). Setting the corners of the polygonal structure as arc guide surfaces facilitates the coordinated installation of the guide fixing plate and the guide groove, and the connecting rod will not slide into the slide groove due to the unchanged corner structure.

[0010] Furthermore, the open end of the threaded hole of the pressure plate has a guide wall, and the diameter of the annular guide wall gradually decreases from the end of the pressure plate to the threaded hole, making it easier for the adjusting screw to be screwed into the threaded hole in the adjusting nut.

[0011] Furthermore, the axial cross-sectional area of ​​the guide fixing plate is smaller than the axial cross-sectional area of ​​the pressure plate. Specifically, the axial cross-sectional area of ​​the guide fixing plate is also smaller than the guide groove, but larger than the slide groove, so that the guide fixing plate can be clamped in the lamp; and the axial cross-sectional area of ​​the pressure bearing plate needs to be clamped on the outer wall of the lamp. The larger the cross-sectional area, the larger the coverage area. The pressure can be dispersed during the tightening process of the adjusting screw, so as not to cause damage to the outer wall of the lamp during the tightening process of the adjusting screw.

[0012] Furthermore, the device also includes a sealing gasket secured to the top wall of the pressure plate. The sealing gasket can be added as needed for installation. Once installed, the gasket is positioned between the outer wall of the lamp and the outer wall of the sheet metal component. The gasket deforms through compression, maintaining close contact with the opening in the sheet metal and providing a sealed connection. When used in conjunction with the adjusting nut body, the sealing structure between the lamp and the sheet metal component is simplified, facilitating installation, increasing product qualification rates, and reducing lamp production costs.

[0013] Furthermore, the sealing gasket is glued and fixed on the top wall of the pressure plate. The gluing installation and fixing method is flexible, convenient and easy to operate.

[0014] Furthermore, an adjusting screw is provided, wherein the length of the screw rod of the adjusting screw is not greater than the length of the threaded hole in the adjusting nut.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] (1) The traditional method of fixing lamps requires the use of very long adjustment screws. Specifically, the adjustment screws are first installed on the lamps, and then the long screws are screwed into the sheet metal, which requires a lot of space for the sheet metal to install the screws. The present solution is to install the adjustment nut on the lamp, and then the adjustment screws are passed through the mounting holes on the sheet metal and screwed into the threaded holes in the adjustment nut, which greatly saves the installation space in the sheet metal.

[0017] (2) A slide groove and a guide groove are set on the lamp, and the connecting rod slides into the slide groove from the slide groove opening, completing the slide groove being fixed in the card slot, completing the installation and fixation of the adjustment nut and the lamp, and the structure is simple and convenient;

[0018] (3) A guide wall is provided at the opening of the threaded hole of the pressure plate to facilitate screwing the adjusting screw into the threaded hole;

[0019] (4) Add a sealing gasket to facilitate sealing between the sheet metal and the lamp. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Example:

[0031] like Figures 1-6As shown, this embodiment provides an adjusting nut 17 for fixing a lamp 16, comprising a guide fixing plate 1, a pressure plate 2, and a connecting rod 3. The connecting rod 3 is located between the guide fixing plate 1 and the pressure plate 2. A threaded hole 4 is provided inside the guide fixing plate 1, the pressure plate 2, and the connecting rod 3. The cross-sectional areas of the guide fixing plate 1 and the pressure plate 2 are both larger than the cross-sectional area of ​​the connecting rod 3. A slot 8 for fixing the lamp 16 is formed between the top wall 5 of the guide fixing plate, the side wall 6 of the connecting rod, and the bottom wall 7 of the pressure plate. In the present solution, the adjusting nut 17 is used for fixing the lamp 16. Specifically, the slot 8 formed between the top wall 5 of the guide fixing plate, the side wall 6 of the connecting rod, and the bottom wall 7 of the pressure plate in the adjusting nut 17 fixes the lamp 16 therein. Then, a bolt is passed through the mounting hole on the sheet metal 9 and screwed into the threaded hole 4 to fix the lamp 16 on the sheet metal. Due to the presence of the adjusting nut 17, the length of the screw rod of the adjusting bolt 10 only needs to be sufficient to be screwed into the threaded hole 4. The length of the bolt in the sheet metal 9 is limited to the height of the bolt cap. Therefore, a large amount of installation space can be saved, solving the problem that the screw rod of the traditional adjusting bolt 10 needs to be fully inserted into the sheet metal, resulting in a large amount of installation space in the sheet metal 9. In addition, the adjusting nut 17 has a simple structure and is easy to install. If a fixing hole is provided on the lamp 16, it is only necessary to insert the connecting rod 3 into the fixing hole on the lamp 16.

[0032] Preferably, the lamp 16 has a slide 11 and a guide groove 12. The diameter of the guide groove 12 is larger than the diameter of the slide 11, and the slide 11 is clamped in the clamping groove 8. The height of the slide 11 is less than the length of the connecting rod 3. The slide 11 is similar to a fixing hole, and the adjustment nut 17 is fixed through the cooperation between the connecting rod 3 and the slide 11. Specifically, during installation, the connecting rod 3 can slide into the slide 11 through the guidance and limitation of the guide groove 12, and then be tightened with the adjustment screw. Because the height of the slide 11 is less than the length of the connecting rod 3, the connecting rod 3 can move within the slide 11 and be adaptively adjusted according to the appropriate position of the adjustment nut 17 on the lamp 16.

[0033] Preferably, the guide fixing plate 1 is a polygonal structure, and the corners are arc guide surfaces 13. Compared with the circular ring shape, the guide fixing plate 1 with a polygonal structure can reduce the space occupied in the lamp 16, and has the installation and fixing effect of being clamped in the guide groove 12 in the lamp 16. Setting the corners of the polygonal structure as arc guide surfaces 13 facilitates the coordinated installation of the guide fixing plate 1 and the guide groove 12, and the connecting rod 3 will not slide into the slide groove 11 due to the unchanged angular structure.

[0034] Preferably, the open end of the threaded hole 4 of the pressure plate 2 has a guide wall 14, and the diameter of the annular guide wall 14 gradually decreases from the end of the pressure plate 2 to the threaded hole 4, making it easier for the adjusting screw to be screwed into the threaded hole 4 in the adjusting nut 17.

[0035] Preferably, the axial cross-sectional area of ​​the guide fixing plate 1 is smaller than the axial cross-sectional area of ​​the pressure plate 2. Specifically, the axial cross-sectional area of ​​the guide fixing plate 1 is also smaller than the guide groove 12, but larger than the slide groove 11, so that the guide fixing plate 1 can be clamped in the lamp 16; and the axial cross-sectional area of ​​the pressure bearing plate 2 needs to be clamped on the outer wall of the lamp 16. The larger the cross-sectional area, the larger the coverage area. The pressure can be dispersed during the tightening process of the adjusting screw, so as not to cause damage to the outer wall of the lamp 16 during the tightening process of the adjusting screw.

[0036] Preferably, a sealing gasket 15 is further included, and the sealing gasket 15 is fixed to the top wall of the pressure plate 2. First, the sealing gasket 15 can be added according to installation needs. After installation, the sealing gasket 15 is located between the outer wall of the lamp 16 and the outer wall of the sheet metal 9. The sealing gasket 15 is deformed by extrusion and always maintains close contact with the opening on the sheet metal to achieve a sealed connection. When the sealing gasket 15 is used in conjunction with the main body of the adjusting nut 17, the sealing structure between the lamp 16 and the sheet metal 9 can be simplified, which facilitates installation, improves product qualification rate, and reduces the production cost of the lamp 16.

[0037] Preferably, the sealing gasket 15 is glued and fixed on the top wall of the pressure plate 2. The gluing installation and fixing method is flexible, convenient and easy to operate.

[0038] An adjusting screw, wherein the length of the screw rod of the adjusting screw is not greater than the length of the threaded hole 4 in the adjusting nut 17.

[0039] like Figure 8 As shown, the guide fixing plate 1, the pressure plate 2, and the connecting rod 3 are coaxially arranged and integrally formed; the upper side of the slide groove 11 and the guide groove 12 are respectively opened, and the connecting rod 3 is inserted into the slide groove 11 through the opening. Since the slide groove 11 is clamped in the clamping groove 8, the diameter of the connecting rod 3 is smaller than the diameter of the slide groove 11. The cross-sectional areas of the guide fixing plate 1 and the pressure plate 2 are larger than the slide groove 11. Moreover, the guide fixing plate 1, the pressure plate 2, and the connecting rod 3 are integrally formed. Therefore, when the connecting rod 3 slides into the slide groove 11, it is necessary to open one side of the slide groove 11. In this way, the connecting rod 3 can slide into the slide groove 11, that is, the slide groove 11 is completely clamped in the clamping groove 8.

[0040] Working principle: When using the adjusting nut 17 in this solution, first slide the connecting rod 3 in the adjusting nut 17 into the slide groove 11 through the opening of the slide groove 11 on the lamp 16. The guide groove 12 and the arc guide surface 1313 play a guiding role during installation; the adjusting nut can move in the slide groove 11. When the adjusting nut moves to the installation position, the connecting rod 3 is positioned in the slide groove 11, and the slide groove 11 is stuck in the slot 8 within the height range. At this time, the adjusting screw is used to pass through the mounting hole on the sheet metal 9, and then inserted into the threaded hole 4 of the adjusting nut 17 to complete the installation of the lamp 16 and the sheet metal 9. The sealing gasket 15 plays a sealing role between the lamp 16 and the sheet metal 9.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
