Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tool manufacturing technology, and in particular to a snap-fit ​​telescopic mechanism. Background Technology

[0002] Modular design is widely used in modern industrial products, especially in the automotive and electronic equipment industries. To facilitate installation, maintenance, or replacement, many modules need to be quickly fixed to the main structure using structures such as snap-fits and limit blocks.

[0003] Especially in the installation of automotive lighting modules, a common method is to use limiting blocks on the vehicle body's mounting structure to snap into the corresponding slots of the lighting module. This fixing method allows for precise positioning and installation of the module. However, when disassembly, repair, or module replacement is required, this snap-fit ​​method often presents difficulties in disassembly. Because the clips are usually designed for one-way insertion, disassembly requires significant force or specialized tools, which can easily damage the clips, limiting blocks, or the module itself, reducing product reliability and lifespan.

[0004] Therefore, there is an urgent need in this field for a snap-fit ​​telescopic mechanism that can achieve both reliable locking and convenient, non-destructive disassembly. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a snap-fit ​​telescopic mechanism, which converts the horizontal pulling force into the vertical lifting and lowering motion of the snap-fit ​​component, thereby realizing the non-destructive and labor-saving disassembly of the module.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0007] A snap-fit ​​telescopic mechanism for controlling the lifting and lowering of a limit block, comprising:

[0008] The mechanism body is provided with linear grooves;

[0009] A pull-out block is slidably disposed in the linear groove. The pull-out block is provided with a slot, and a guide rail is provided around the slot. The inclination of the guide rail varies along its extension direction.

[0010] A lifting column is movably mounted on the main body of the mechanism. The upper end of the lifting column is provided with a slot, which extends into the slot opening. The guide rail is disposed in the slot.

[0011] The limiting block is located at the free end of the lifting column;

[0012] When the pull block is driven to slide along the linear groove, the linear movement of the inclined guide rail in the slot causes the lifting column to rise and fall. When the lifting column descends, the limiting block disengages from the limiting hole.

[0013] According to one aspect of the present invention, the front end of the pull-out block is provided with a handle.

[0014] According to one aspect of the present invention, the front end of the pull-out block is provided with a screw hole, and the handle is fixed to the front end of the pull-out block by screws.

[0015] According to one aspect of the present invention, the lifting column includes a horizontal column and a vertical column, the slot is disposed at the top of the vertical column, the lower end of the vertical column is connected to one end of the horizontal column, and the limiting block is disposed at the other end of the horizontal column.

[0016] According to one aspect of the present invention, a fixing plate is connected to one side of the mechanism body, and the fixing plate is provided with mounting holes for fixing the mechanism body to an external module.

[0017] According to one aspect of this utility model, the mounting hole includes a pin hole and a screw hole, and there are two pin holes and two screw holes.

[0018] According to one aspect of this utility model, the lifting column is movably connected to the mechanism body via wedges and pins.

[0019] According to one aspect of the present invention, the snap-fit ​​telescopic mechanism further includes a set bolt, and the upper end of the lifting column is provided with a threaded hole that mates with the set bolt;

[0020] When the set bolt is screwed into the threaded hole, the nut of the set bolt, the upper end face of the lifting column, and the threaded part between them form the groove.

[0021] According to one aspect of the present invention, the pull-out block has weight-reducing holes on its body near the front end.

[0022] According to one aspect of the present invention, the inclination of the guide rail varies linearly along its extension direction.

[0023] The advantages of this utility model are as follows: First, the vertical lifting of the column can be precisely controlled through a simple horizontal pulling action, thereby achieving the locking and unlocking of the limit block. The disassembly process is labor-saving and requires no special tools, completely solving the problem of difficult disassembly of traditional buckle structures. Second, the force transmission is achieved by using the principle of inclined guide rails, resulting in smooth and controllable movement. This avoids the risk of excessive wear or forced breakage of the limit block, module slot, and other structures during disassembly, improving the reliability and service life of the entire connection system. Third, the mechanism has a compact structure, ingenious design, and is easy to manufacture and assemble. It is not only suitable for vehicle lighting modules but can also be widely used in other modular products that require quick assembly and disassembly, demonstrating strong adaptability.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a snap-fit ​​telescopic mechanism is used to control the lifting and lowering of a limit block 400, including a mechanism body 100, a pull-out block 200, and a lifting column 300.

[0054] The mechanism body 100 is provided with a linear groove 102; the pull-out part of the pull-out block 200 is provided with a slot 201, and a guide rail 202 is provided around the slot 201, the inclination of the guide rail 202 varies along its extension direction; the upper end of the lifting column 300 is provided with a slot 305, and a limiting block 400 is provided at the free end of the lifting column 300.

[0055] During assembly, the pull block 200 is slidably disposed in the linear groove 102 of the mechanism body 100; the lifting column 300 is movably disposed on the mechanism body 100; the slot 305 of the lifting column 300 extends into the slot 201 of the pull block 200, and the guide rail 202 around the slot 201 is located in the slot 305 of the lifting column 300.

[0056] After the mechanism is assembled, the upper and lower surfaces of the guide rail 202 and the upper and lower walls of the slot 305 fit tightly together. At this time, when the drive pull block 200 slides along the linear groove 102, the guide rail 202 is confined to slide within the slot 305. Since the guide rail 202 has an inclination, the linear movement of the pull block 200 will drive the lifting column 300 to rise or fall, thereby causing the limiting block 400 to enter or leave the limiting hole.

[0057] The thickness of the pull-out portion of the pull-out block 200 is adapted to the linear groove 102 of the mechanism body 100, and the thickness of the pull-out portion is less than that of other parts of the pull-out block 200 body, thus creating a step 205 at their joint. When the pull-out block 200 is pulled all the way out, the outer side plate of the linear groove 102 abuts against this step 205, thereby restricting the movement of the pull-out block 200.

[0058] For ease of gripping, a handle 203 is provided at the front end of the pull-out block 200. In this embodiment of the utility model, a screw hole is provided at the front end of the pull-out block 200, and the handle 203 is fixed to the front end of the pull-out block 200 by screws.

[0059] Meanwhile, the pull-out block 200 also has a weight-reducing hole 204 on its body near the front end. The screw hole for fixing the handle 203 passes through this weight-reducing hole 204 from the front end of the pull-out block 200. When assembling the handle 203, the screw on the handle 203 passes through the screw hole, with the front end of the screw located inside the weight-reducing hole 204. Then, the nut is tightened to fix the handle 203.

[0060] In this embodiment of the utility model, the lifting column 300 includes a horizontal column 301 and a vertical column 302. The slot 305 is disposed at the top of the vertical column 302. The lower end of the vertical column 302 is connected to one end of the horizontal column 301. The other end of the horizontal column 301 is the free end of the lifting column 300. The limiting block 400 is disposed on this free end.

[0061] A fixing plate 101 is connected to one side of the mechanism body 100. The fixing plate 101 is provided with mounting holes for fixing the mechanism body 100 to the external module. In this embodiment of the present invention, the mounting holes include pin holes 104 and screw holes 105, with two pin holes 104 and two screw holes 105, and the two pin holes 104 and two screw holes 105 are arranged diagonally. By inserting a positioning pin into the pin hole 104, the mechanism body 100 can be accurately positioned on the module, and then the mechanism body can be fixed on the module by screwing in screws into the screw holes 105.

[0062] In this embodiment, the lifting column is movably connected to the mechanism body 100 via a wedge 303 and a pin 304. The wedge 303 is cylindrical, with a first arc-shaped notch 303a on its side wall. Simultaneously, the mechanism body 100 has a circular opening 103 in the vertical direction, and the side plate of the opening 103 also has a second arc-shaped notch 103a. During assembly, these two notches are aligned, and the pin 304 is inserted, allowing the lifting column 300 to move vertically within a certain range within the circular opening 103 of the mechanism body 100, but preventing lateral movement.

[0063] The slot 305 at the upper end of the lifting column 300 can be integrally machined with the lifting column 300. In actual production, to reduce processing difficulty and cost, a separate processing design can also be adopted, as long as a concave slot 305 mechanism can be formed at the upper end of the lifting column 300. This utility model does not impose any special limitations.

[0064] To reduce costs and processing difficulty, the upper end of the lifting column 300 is provided with a threaded hole of a certain depth. During assembly, the set bolt 500 is screwed into the threaded hole. At this time, the nut of the set bolt 500, the upper end face of the lifting column 300 and the threaded part between them form a concave groove. This groove is the retaining groove 305 with a limiting function.

[0065] To facilitate tightening of the set bolt 500, the nut of the set bolt 500 is provided with a cross groove, so that it can be easily operated using a general-purpose Phillips screwdriver.

[0066] To facilitate pulling the pull block 200, in this embodiment of the utility model, the inclination of the guide rail 202 can be designed to change linearly along its extension direction. This way, when the guide rail 202 slides in the slot 305, the force on its bearing surface is uniform, which saves effort and is less likely to damage the guide rail 202 and the slot 305.

[0067] The advantages of this utility model are as follows: First, the vertical lifting of the column can be precisely controlled through a simple horizontal pulling action, thereby achieving the locking and unlocking of the limit block. The disassembly process is labor-saving and requires no special tools, completely solving the problem of difficult disassembly of traditional buckle structures. Second, the force transmission is achieved by using the principle of inclined guide rails, resulting in smooth and controllable movement. This avoids the risk of excessive wear or forced breakage of the limit block, module slot, and other structures during disassembly, improving the reliability and service life of the entire connection system. Third, the mechanism has a compact structure, ingenious design, and is easy to manufacture and assemble. It is not only suitable for vehicle lighting modules but can also be widely used in other modular products that require quick assembly and disassembly, demonstrating strong adaptability.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
