[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1The utility model provides an embodiment: a linear guide rail that is easy to quickly connect and assemble, including a guide rail body 1, and the front and rear surfaces of the guide rail body 1 are provided with slide grooves 2. The slider can be installed on the guide rail body 1 through the left and right ends of the guide rail body 1 and cooperate with the slide grooves 2 for sliding connection. A docking component is provided on the outside of the guide rail body 1.

[0036] Reference Figure 3-Figure 5 The docking assembly includes: a docking block 301, a docking groove 305 and a circular groove 310. The docking block 301 is fixedly connected to the left end of the guide rail body 1. The left end of the docking block 301 is arranged in a pointed structure. A card slot 302 is provided on the upper surface of the docking block 301. The docking groove 305 is arranged on the right side surface of the guide rail body 1. When two guide rail bodies 1 are docked and installed, the docking block 301 and the docking groove 305 on the opposite side can be plugged in, so as to perform preliminary positioning of the two guide rail bodies 1. The pointed structure at the left end of the docking block 301 can reduce the docking difficulty between the docking block 301 and the docking groove 305, and speed up the docking speed.

[0037] The inner top surface of the docking groove 305 is provided with a limit groove 306, and the inner bottom end of the limit groove 306 is provided with a block 307. The bottom end of the right surface of the block 307 is chamfered. The sizes of the slot 302 and the block 307 are adapted to each other. The top of the block 307 is fixedly connected with a connecting rod 308. When the connecting rod 308 moves, it can drive the block 307 to move synchronously. The block 307 is sleeved with the inner part of the limit groove 306. The limit groove 306 can guide and limit the movement of the block 307, so that The block 307 can only perform linear movement in the up and down directions. A spring 309 is sleeved on the outer side of the connecting rod 308. The bottom end of the spring 309 is fixedly connected to the upper surface of the block 307. The upper end of the spring 309 is fixedly connected to the inner top surface of the limit groove 306. When the block 307 moves upward, the spring 309 is squeezed, so that the spring 309 is compressed to generate elastic potential energy. When the docking block 301 enters the docking groove 305, it will squeeze the block 307 along the inclined surface of the block 307, so that the block 307 enters the limiting groove 306. When the docking block 301 completely enters the docking groove 305, the slot 302 will be aligned with the limiting groove 306. At this time, the block 307 will enter the slot 302 downward under the elastic potential energy of the spring 309 to engage and limit the docking block 301, completing the docking assembly. The circular groove 310 is provided at the right end of the upper surface of the guide rail body 1. A connecting block 311 is provided inside the circular groove 310. The upper surface of the connecting block 311 is provided with an inner groove. The connecting rod 30 The top of 8 passes through the guide rail body 1, and the top of the connecting rod 308 is fixedly connected to the bottom surface of the connecting block 311. When the two guide rail bodies 1 need to be disassembled, the staff can hook their fingers into the inner groove to directly pull up the connecting block 311, and then drive the card block 307 to move upward through the connecting rod 308, so that the card block 307 is disengaged from the card slot 302, and the card limit to the docking block 301 is released, so that the docking block 301 can be pulled out of the docking slot 305 for disassembly, which is easy to operate.

[0038] A sealing groove 303 is provided at the left end of the guide rail body 1, and a sealing frame 304 is fixedly connected to the right end of the guide rail body 1. The sizes of the sealing groove 303 and the sealing frame 304 are adapted to each other, the outer surface of the filter 403 fits with the inner wall of the oil collecting frame 401, and the sizes of the sealing groove 303 and the sealing frame 304 are the same as the outer circle size of the end of the guide rail body 1. When the two guide rail bodies 1 are docked, the sealing frame 304 will be inserted into the sealing groove 303 to seal the connection between the two guide rail bodies 1 to avoid gaps that affect the passage of the slider.

[0039] Reference Figure 1-Figure 2The bottom ends of the front and rear surfaces of the guide rail body 1 are fixedly connected with oil collecting frames 401. When the lubricating oil in the slider, the guide rail body 1 and the slide groove 2 slides downward, it will enter the oil collecting frame 401 for collection. A pipeline and a circulation pump can be set at the end of the oil collecting frame 401 so that the lubricating oil can be recycled to avoid waste. The front and rear inner wall surfaces of the oil collecting frame 401 are fixedly connected with fixed rods 402. A filter screen 403 is set above the fixed rod 402. The filter screen 403 can be set in the form of filter cloth, which can filter the debris mixed in the lubricating oil due to the wear of the guide rail. The filter 403 is filtered to prevent debris from returning to the guide rail and causing secondary wear during recycling. A U-shaped handle 404 is fixedly connected to the end of the upper surface of the filter 403 away from the guide rail body 1. The U-shaped handle 404 is sleeved on the outer side of the end of the oil collecting frame 401 away from the guide rail body 1. The fixed rod 402 can support the bottom end of the filter 403 to prevent impurities from accumulating on the filter 403, causing it to be slightly bent and stuck inside the oil collecting frame 401 and difficult to remove. The staff can use the U-shaped handle 404 to quickly pick up and clean the filter 403, and at the same time avoid directly picking up the filter 403 and causing the hands to be stained with lubricating oil.

[0040] Working principle: When two guide rail bodies 1 need to be docked and assembled, the docking block 301 can be aligned with the inside of the docking groove 305 for plugging. When the docking block 301 completely enters the docking groove 305, the clamping block 307 will enter the clamping groove 302 to clamp and limit the docking block 301, and the docking and assembly of the two guide rail bodies 1 can be completed. The operation is simple. When the guide rail body 1 needs to be disassembled, only the finger needs to be hooked into the inner groove to lift the connecting block 311 upward to release the clamping limit of the guide rail body 1. The lubricating oil dripping downward during the use of the linear guide can enter the oil collecting frame 401 and be filtered by the filter screen 403 for recycling, thereby avoiding waste and preventing the lubricating oil from leaking onto the work surface and causing pollution.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
