Description

Technical Field

[0001] This utility model relates to the field of electric door guide rails, and specifically refers to an electric door guide rail structure. Background Technology

[0002] Electric gates play a crucial role in our daily lives, offering safety, aesthetics, convenience, and ease of use, greatly improving our quality of life. However, electric gates are susceptible to various external factors during operation. Dust and debris from the ground can easily enter the tracks, leading to a buildup over time. This accumulation of dust and debris can affect the normal operation of the gate, and the track surface is prone to corrosion, increasing friction between the ball bearing assembly and the track, potentially causing the gate to move and hindering its use.

[0003] The prior art 202420762871.6 discloses an electric door guide rail structure. Although it can clean up garbage and dust, the dust and garbage will still fall into the slide rail. Although it lubricates the ball bearings through the oil storage chamber and oil storage cotton, the oil storage cotton will continuously lubricate the ball bearings, which cannot achieve timed and quantitative lubrication, thus resulting in the waste of lubricating oil. Utility Model Content

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Appendix Figure 1-3The electric door guide rail structure of this utility model includes a fixed base 1, a slide rail 2 disposed on the fixed base 1, a plurality of ball bearings 3 respectively disposed on the inner walls and bottom sides of the slide rail 2, and a lubrication assembly 4 disposed in the fixed base 1 and below the ball bearings 3 for providing a quantitative amount of lubricating oil to the ball bearings 3. The slide rail 2 is provided with a mounting seat 8, an electric door body 5 disposed on the mounting seat 8, and two bellows covers 6 telescopically disposed at both ends of the slide rail 2 and respectively connected to the end faces of the mounting seat 8 for sealing the slide rail 2. The lubrication assembly 4 includes multiple three-stage oil channels 41 spaced apart in the fixed base 1 and corresponding to multiple ball bearings 3 directly below the ball bearings 3, a plurality of oil overflow channels 42 disposed in the fixed base 1 and connected at both ends to the ball bearings 3 and the three-stage oil channels 41 for overflowing oil, and a three-stage oil overflow channel 42 disposed in the bottom end of the fixed base 1 and located at the bottom end of the fixed base 1. The four secondary oil passages 43 of the tertiary oil passage 41 on one side of the oil passage 41 and the side wall of the fixed base 1 are respectively arranged in the side walls of both sides of the fixed base 1 and located between the two secondary oil passages 43. An oil supply assembly 45 is arranged on the outside to supply oil to the two primary oil passages 44. The four secondary oil passages 43 are respectively connected to the middle of the corresponding multiple tertiary oil passages 41. The two primary oil passages 44 are respectively connected to the middle of the four secondary oil passages 43. The oil supply assembly 45 includes a mounting box 451, an oil storage chamber 452 arranged at the upper end of the mounting box 451 for storing oil, an oil pump 453 arranged in the bottom of the mounting box 451 and whose input end is connected to the bottom of the oil storage chamber 452, and a splitter 454 arranged in the bottom of the mounting box 451 and whose input end is connected to the output end of the oil pump 453. The splitter 454 is connected to the two primary oil passages 44 respectively through connecting pipes.

[0015] Furthermore, the diameter of several of the oil overflow channels 42 gradually increases from the position near the oil inlet of the third-level oil channel 41 to avoid uneven oil overflow.

[0016] Furthermore, photoelectric sensors 7 are provided on both ends of the slide rail 2 to sense the number of times the electric door is opened.

[0017] Furthermore, the fixed base 1 has a two-layer structure; the primary oil passage 44, the secondary oil passage 43 and the tertiary oil passage 41 are all located on the connecting surface of the two-layer structure of the fixed base 1, which facilitates processing and maintenance.

[0018] In use: Lubrication is achieved by setting the number of times the electric door opens via an external control device, or by using a cycle. When the number of openings is reached or the cycle is completed, the oil pump 453 is started first. Then, the oil pump 453 draws oil from the oil storage chamber 452 and then pumps it into two primary oil passages 44 through the distributor 454. The oil then enters the secondary oil passage 43 through the primary oil passage 44, and then enters the tertiary oil passage 41 through the secondary oil passage 43. Since the secondary oil passage 43 is connected to the tertiary oil passage 41... In the middle, the oil enters the third-stage oil passage 41 and flows to both sides. Then, the oil enters the ball bearing 3 cavity through the overflow oil passage 42 to lubricate the ball bearing 3. Since the third-stage oil passage 41 is located below the ball bearing 3, the overflow oil passage 42 will only overflow the amount of lubricant and will not overflow excess lubricant, thus achieving timed and quantitative lubrication and effectively avoiding the waste of lubricant. In addition, the bellows cover 6 will also extend or retract with the movement of the electric door, thus effectively preventing external dust and garbage from falling into the slide rail 2 and affecting the ball bearing 3.

[0019] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
