Description

Technical Field

[0001] This utility model relates to the field of guide rail height adjustment technology, specifically a single-segment guide rail height adjustment structure. Background Technology

[0002] The rails are typically installed using a multi-segment splicing method, with each segment fixed in its corresponding position by mounting brackets. During installation, the rails are first secured to the mounting brackets with screws, and the brackets are then fixed to the mounting base. After the overall installation is complete, the levelness between adjacent rail segments needs to be adjusted. Currently, this adjustment is generally achieved by adjusting the height of the mounting brackets. However, this method makes it difficult to achieve fine-tuning of the rail height in actual operation, affecting installation accuracy and efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a single-segment guide rail height adjustment structure, which makes the height of the single-segment guide rail easy to fine-tune.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-segment guide rail height adjustment structure, including a mounting bracket connected to the bottom of the guide rail. Two sets of symmetrically arranged fine-tuning structures are connected to the top surface of the mounting bracket. Each fine-tuning structure includes two L-shaped blocks, which are slidably connected to the top surface of the mounting bracket. Both L-shaped blocks are located on the same side of the guide rail. The inner wall of each L-shaped block has a beveled edge, and the outer walls of the guide rail abut against the beveled edge on both sides. A waist-shaped groove is formed within the L-shaped block, and a first screw passes through the waist-shaped groove. Guide grooves are provided on both sides of the guide rail, and threaded plates are engaged within the guide grooves. The first screw passes through the outer side of one end of the waist-shaped groove and is threadedly connected to the threaded plate. Two symmetrically arranged fastening structures are installed on the top surface of the mounting bracket.

[0005] Furthermore, each of the fastening structures includes an L-shaped mounting plate located between two L-shaped blocks on the same side of the guide rail. The horizontal plate of the L-shaped mounting plate is threaded with two second screws, one end of which passes through the horizontal plate of the L-shaped mounting plate and is threaded to the mounting bracket. The vertical plate of the L-shaped mounting plate is threaded with two third screws, one end of which passes through the vertical plate of the L-shaped mounting plate and is threaded to the threaded plate located in the guide groove.

[0006] Furthermore, a coaxial ring is fitted on the end of the first screw away from the threaded plate, and the coaxial ring is slidably connected to the first screw. A U-shaped rod is connected between the coaxial rings located on the same side of the guide rail.

[0007] Furthermore, the bottom of each of the two vertical bars of the U-shaped rod is fixedly connected to a connecting plate, the bottom of the connecting plate is fixedly connected to an arrow, and the outer wall of the L-shaped block is provided with scale lines.

[0008] Furthermore, the U-shaped rod and the coaxial ring are detachably connected by screws.

[0009] Furthermore, a first washer is connected to the side of the coaxial ring near the L-shaped block.

[0010] Furthermore, the second and third screws are each fitted with a second washer on the side that is close to the L-shaped mounting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes the interlocking structure of the beveled edge on the L-shaped block, the first screw, and the threaded plate to achieve fine-tuning of the guide rail height. When adjusting the guide rail height, simply rotate the first screw, causing the L-shaped blocks on both sides to move closer or further apart. The beveled edge allows the guide rail to smoothly rise and fall between the two symmetrically arranged L-shaped blocks, thus achieving precise fine-tuning of the guide rail height. This makes the adjustment process more accurate and easier to control. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 6 As shown, a single-section guide rail height adjustment structure includes a mounting bracket 2 connected to the bottom of the guide rail 1. The top surface of the mounting bracket 2 is connected to two sets of symmetrically arranged fine-tuning structures. Each fine-tuning structure includes two L-shaped blocks 4. The two L-shaped blocks 4 are slidably connected to the top surface of the mounting bracket 2. The two L-shaped blocks 4 are located on the same side of the guide rail 1. The inner wall of the L-shaped block 4 is provided with a bevel 41. The two sides of the outer wall of the guide rail 1 abut against the bevel 41 respectively. A waist-shaped groove 12 is opened in the L-shaped block 4. A first screw 3 passes through the waist-shaped groove 12. Guide grooves 101 are provided on both sides of the guide rail 1. A threaded plate 8 is engaged in the guide groove 101. The first screw 3 passes through the outer side of one end of the waist-shaped groove 12 and is threadedly connected to the threaded plate 8. Two symmetrically arranged fastening structures are installed on the top surface of the mounting bracket 2.

[0022] like Figures 1 to 6 As shown, in the single-section guide rail height adjustment structure of this utility model, when the guide rail 1 is installed, the guide rail 1 is first connected to the mounting bracket 2 through the fastening structure, so that the guide rail 1 is located between the L-shaped blocks 4 of the two sets of fine adjustment structures. Then, the first screw 3 of the two sets of fine adjustment structures passes through the L-shaped block 4 and is threadedly connected to the threaded plate 8 located in the guide groove 101. After the first screw 3 on the two sets of L-shaped blocks 4 is threadedly connected to the corresponding threaded plate 8, the first screw 3 can be rotated, so that the first screw 3 moves in the waist-shaped groove 12 of the L-shaped block 4, and the end of the first screw 3 is threadedly connected to the threaded plate 8. At this time, the first screw 3 presses the corresponding L-shaped block 4 to slide forward, so that the inclined side 41 abuts against the outer wall of the guide rail 1. In this way, the height of the guide rail 1 can be adjusted under the restriction of the inclined side 41.

[0023] The height of the guide rail 1 can be finely adjusted by the engagement structure between the inclined edge 41 on the L-shaped block 4, the first screw 3, and the threaded plate 8. When the height of the guide rail 1 needs to be adjusted, simply rotate the first screw 3 to move the L-shaped blocks 4 on both sides closer or further apart. Utilizing the inclined edge 41, the guide rail 1 can smoothly rise and fall between the two symmetrically arranged L-shaped blocks 4, thereby completing precise fine-tuning of the height of the guide rail 1, making the adjustment process more accurate and easier to control.

[0024] like Figure 3 , Figure 4 and Figure 5As shown, each fastening structure includes an L-shaped mounting plate 5, which is located between two L-shaped blocks 4 on the same side of the guide rail 1. The horizontal plate of the L-shaped mounting plate 5 is threaded with two second screws 6. One end of the two second screws 6 passes through the horizontal plate of the L-shaped mounting plate 5 and is threaded to the mounting bracket 2. The vertical plate of the L-shaped mounting plate 5 is threaded with two third screws 7. One end of the two third screws 7 passes through the vertical plate of the L-shaped mounting plate 5 and is threaded to the threaded plate 8 located in the guide groove 101.

[0025] Specifically, in order to make the connection between the mounting bracket 2 and the guide rail 1 more stable, the second screw 6 can be threaded through the L-shaped mounting plate 5 and then threaded to the mounting bracket 2. The third screw 7 can be threaded through the L-shaped mounting plate 5 and threaded to the threaded plate 8. It is worth noting that the slots through which the second screw 6 and the third screw 7 pass through the L-shaped mounting plate 5 should be oblong slots. This ensures that when the height of the guide rail 1 is finely adjusted, the second screw 6 and the third screw 7 can move upward accordingly.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a coaxial ring 9 is fitted on the end of the first screw 3 away from the threaded plate 8. The coaxial ring 9 is slidably connected to the first screw 3. A U-shaped rod 10 is connected between the coaxial rings 9 on the same side of the guide rail 1.

[0027] Specifically, the first screw 3 passes through the coaxial ring 9 and is threaded to the threaded plate 8. Using the U-shaped rod 10, when one of the first screws 3 on the same side is rotated, the other first screw 3 on the same side will be driven to rise and fall. Before this, the other first screw 3 on the same side is not threaded to the threaded plate 8, ensuring that the U-shaped rod 10 can smoothly drive the other first screw 3 to rise and fall. After the position is adjusted, the first screw 3 on the other side is also adjusted in the same way. Then, the other first screw 3 on both sides of the guide rail 1 is fixed to the threaded plate 8. That is to say, when one of the first screws 3 in each group is rotated, the other first screw 3 in the same group is not threaded to the threaded plate 8. One first screw 3 plays the role of limiting the height position of the guide rail 1, and the other first screw 3 plays the role of final reinforcement and balance.

[0028] like Figure 2 , Figure 5 and Figure 6 As shown, the bottom of the two vertical rods of the U-shaped rod 10 is fixedly connected to the connecting plate 14, and the bottom of the connecting plate 14 is fixedly connected to the arrow 15. The outer wall of the L-shaped block 4 is provided with scale lines 11.

[0029] Specifically, when the U-shaped rod 10 rises and falls along with the coaxial ring 9 and the first screw 3, it will drive the connecting plate 14 and the arrow 15 to rise and fall. The rising and falling position and distance can be clearly known by using the scale line 11.

[0030] like Figure 2 and Figure 5 As shown, the U-shaped rod 10 and the coaxial ring 9 are detachably connected by screws 13. The U-shaped rod 10 and the coaxial ring 9 can be detachably installed using screws 13.

[0031] like Figure 6 As shown, a first washer is connected to the side of the coaxial ring 9 near the L-shaped block 4. The first washer facilitates increased friction when the coaxial ring 9 and the L-shaped block 4 are connected.

[0032] like Figure 3 and Figure 5 As shown, the second screw 6 and the third screw 7 are both fitted with second washers on the side of the L-shaped mounting plate 5 that is close to it. The second washers increase the friction between the second screw 6 and the third screw 7 during installation.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
