Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, and in particular to a high wear-resistant guide rail that is easy to install sliders. Background Technology

[0002] A guide rail is a device made of highly wear-resistant metal or other materials, consisting of grooves or ridges, that can support, fix, and guide moving devices or equipment. Guide rails are also known as slide rails, linear guide rails, or linear slide rails.

[0003] Patent CN216045012U discloses a high wear-resistant guide rail for easy installation of sliders, belonging to the field of guide rail technology. This high wear-resistant guide rail for easy installation of sliders includes: a slide rail body, with a snap-fit ​​sliding groove at the upper end of the slide rail body, snap-fit ​​limiting grooves on the front and rear inner walls of the snap-fit ​​sliding groove, and two external sliding grooves at both the front and rear ends of the slide rail body; a convenient installation sliding mechanism, which is slidably connected to the two snap-fit ​​limiting grooves to achieve convenient installation and sliding limitation of the slider; and an adjustable installation slider mechanism, which is slidably connected to the four external sliding grooves to achieve stable sliding of the slider. This device utilizes the convenient installation sliding mechanism and the adjustable installation slider mechanism to achieve simple and stable installation of the entire slider and slide rail body, simplifying the overall installation steps and improving the practicality of the device.

[0004] However, the aforementioned high wear-resistant guide rail, which facilitates the installation of sliders, still has the following shortcomings:

[0005] In the aforementioned guide rail, the locking sliding block is always engaged in the locking limiting groove inside the slide rail body. Since the locking sliding block needs to make sliding linear motion inside the slide rail body, the contact sliding friction between the slide rail and the slider is relatively large, which easily causes wear of the slider over a long period of time. However, the locking sliding block is difficult to disassemble and replace separately, which means that the slide rail body needs to be replaced together with the locking sliding block, increasing the replacement cost. In view of this, we propose a high wear-resistant guide rail that is easy to install sliders. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high wear-resistant guide rail that is easy to install sliders. This solves the problem that in the above-mentioned guide rails, the snap-fit ​​sliding block is always locked in the snap-fit ​​limiting groove inside the slide rail body. Since the snap-fit ​​sliding block needs to make sliding linear motion inside the slide rail body, the contact sliding friction between the slide rail and the slider is large, which easily causes wear of the slider over a long period of time. However, the snap-fit ​​sliding block is difficult to disassemble and replace separately, which leads to the slide rail body needing to be replaced together with the snap-fit ​​sliding block, increasing the replacement cost.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a high wear-resistant guide rail that is easy to install sliders, including a guide rail body, an inner slider assembly is engaged inside the guide rail body, an outer slider assembly is engaged outside the guide rail body, and an installation plate is fixedly connected to the outer surface of the outer slider assembly.

[0008] The inner slider assembly includes a limiting frame that engages inside the guide rail body. A positive and negative lead screw is mounted on the upper part of the limiting frame. A knob is connected to the end of the positive and negative lead screw. A set of movable plates is symmetrically fitted on the surface of the positive and negative lead screw. A limiting block is connected to the bottom of the movable plate.

[0009] Preferably, the positive and negative lead screws are threadedly connected to the movable plate, and the movable plate and the limiting block are integrally formed.

[0010] Preferably, the limiting frame is hollow inside, and the combination of the movable plate and the limiting block is matched and engaged inside the limiting frame.

[0011] Preferably, the guide rail body includes a linear track, the inner side of the linear track is provided with an inner groove, the outer side of the linear track is provided with an outer groove, and positioning plates are provided at both ends of the linear track, the positioning plates and the linear track being integrally formed.

[0012] Preferably, the outer slider assembly includes a slot frame, which is fixed to the top of the limiting frame. A locking plate is engaged inside the slot frame, and the slot frame and the locking plate are connected by bolts. A slide is connected to one side of the locking plate, and a locking block is provided on the side of the slide away from the mounting plate.

[0013] Preferably, the carriage and the locking block are integrally formed, and the locking block is matched and engaged inside the outer sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a knob to rotate the positive and negative lead screws, causing a set of movable plates on the surface of the positive and negative lead screws to move away from each other. At this time, the limiting block can be effectively engaged in the inner slide groove, quickly realizing the installation between the inner slider assembly and the guide rail body. When the inner slider assembly is worn and needs to be replaced, the knob is rotated to rotate the positive and negative lead screws, causing a set of movable plates on the surface of the positive and negative lead screws to move closer to each other. At this time, the limiting block moves out of the inner slide groove and is hidden inside the limiting frame. At this time, the inner slider assembly is unrestrained and can be directly pulled out of the guide rail body, which is convenient for individual replacement and reduces replacement costs.

[0016] 2. In this utility model, the slot frame and the card plate can be separated by removing the bolts, and then the card block can be separated from the outer sliding groove by moving the slide outward, which facilitates the quick disassembly of the outer slider assembly. The mounting plate on the surface of the slide is used to connect with the moving device. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] A high wear-resistant guide rail that facilitates slider installation, see [link / reference]. Figures 1 to 4 It includes a guide rail body 1, an inner slider assembly 2 is engaged inside the guide rail body 1, an outer slider assembly 3 is engaged outside the guide rail body 1, and a mounting plate 4 is fixed to the outer surface of the outer slider assembly 3.

[0027] The inner slider assembly 2 includes a limiting frame 201, which is engaged inside the guide rail body 1. A positive and negative lead screw 202 is mounted on the upper part of the limiting frame 201. A knob 203 is connected to the end of the positive and negative lead screw 202. A set of movable plates 204 are symmetrically mounted on the surface of the positive and negative lead screw 202. A limiting block 205 is connected to the bottom of the movable plate 204. The positive and negative lead screw 202 and the movable plate 204 are threaded together. The movable plate 204 and the limiting block 205 are integrally formed. Furthermore, the interior of the limiting frame 201 is hollow. The combination of the movable plate 204 and the limiting block 205 is matched and engaged inside the limiting frame 201. This invention uses a knob 203 to rotate the positive and negative lead screws 202, causing a set of movable plates 204 on the surface of the positive and negative lead screws 202 to move away from each other. At this time, the limiting block 205 can be effectively engaged in the inner slide groove 102, quickly realizing the installation between the inner slider assembly 2 and the guide rail body 1. When the inner slider assembly 2 is worn and needs to be replaced, the knob 203 is rotated to rotate the positive and negative lead screws 202, causing the set of movable plates 204 on the surface of the positive and negative lead screws 202 to move closer to each other. At this time, the limiting block 205 moves out of the inner slide groove 102 and is hidden inside the limiting frame 201. At this time, the inner slider assembly 2 is not constrained and can be directly pulled out of the guide rail body 1, which is convenient for individual replacement and reduces replacement costs.

[0028] It is worth noting that the guide rail body 1 includes a linear track 101, an inner groove 102 on the inner side of the linear track 101, an outer groove 103 on the outer side of the linear track 101, and positioning plates 104 at both ends of the linear track 101. The positioning plates 104 are integrally formed with the linear track 101. In this utility model, the inner groove 102 is used to limit the positioning block 205, and the outer groove 103 is used to limit the locking block 305.

[0029] It is worth noting that the outer slider assembly 3 includes a slot frame 301, which is fixed to the top of the limiting frame 201. A retaining plate 302 is engaged inside the slot frame 301, and the slot frame 301 and the retaining plate 302 are connected by bolts 303. A slide 304 is connected to one side of the retaining plate 302, and a retaining block 305 is provided on the side of the slide 304 away from the mounting plate 4. The slide 304 and the retaining block 305 are integrally formed, and the retaining block 305 is matched and engaged inside the outer sliding groove 103. In this utility model, the slot frame 301 and the retaining plate 302 can be separated by removing the bolts 303, and then the retaining block 305 can be separated from the outer sliding groove 103 by moving the slide 304 outward, which facilitates the quick disassembly of the outer slider assembly 3. The mounting plate 4 on the surface of the slide 304 is used to connect with the moving device.

[0030] Working principle: The guide rail body 1 is installed in the desired position using the positioning plate 104. Then, the inner slider assembly 2 is placed inside the guide rail body 1. Turning the knob 203 rotates the positive and negative lead screws 202, causing a set of movable plates 204 on the surface of the positive and negative lead screws 202 to move away from each other. At this time, the limiting block 205 can be engaged in the inner slide groove 102, quickly realizing the installation between the inner slider assembly 2 and the guide rail body 1. Then, the clamping plate 302 is inserted into the slot frame 301 and connected by bolts 303. At this time, the clamping block 305 is engaged inside the outer slide groove 103, quickly realizing the installation between the outer slider assembly 3 and the guide rail body 1. After installation, the moving device can be installed on the surface of the mounting plate 4. When the inner slider assembly 2 is worn and needs to be replaced, first remove the bolt 303 to separate the slot frame 301 from the clamping plate 302, so that the slide 304 and the clamping block 305 can be removed from the guide rail body 1. Then, turn the knob 203 to drive the positive and negative lead screws 202 to rotate, so that a set of movable plates 204 fitted on the surface of the positive and negative lead screws 202 move closer to each other. At this time, the limiting block 205 moves out of the inner slide groove 102 and the limiting block 205 is hidden inside the limiting frame 201. At this time, the inner slider assembly 2 is not constrained and can be directly pulled out of the guide rail body 1, which is convenient for individual replacement and reduces replacement costs.
