Description

Technical Field

[0001] This utility model relates to the field of automatic sensor door technology, and in particular to a telescopic structure for an automatic sensor door. Background Technology

[0002] In existing technologies, automatic sensor doors are widely used at various building entrances to improve passage efficiency and security. The telescopic structure is a key component for achieving automatic opening and closing of the door. Currently, the most common telescopic structures for automatic sensor doors on the market employ a design of sliding rails with pulleys or sliders, driven by a motor to move the door. However, these existing technological solutions have the following drawbacks:

[0003] Insufficient lubrication: In traditional designs, the friction surfaces between the slide rail and the pulley or slider lack effective lubrication, resulting in severe wear after long-term operation, affecting the stability and service life of the door.

[0004] High maintenance costs: Due to poor lubrication, lubricant needs to be added manually every time, which increases the complexity and cost of maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a telescopic structure for an automatic sensor door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a telescopic structure for an automatic sensor door, comprising a slide rail, a glass door, and an oil storage box. Three protrusions are provided on both sides of the interior of the slide rail. An opposing lead screw is mounted inside the slide rail via bearings. A servo motor is provided on one side of the slide rail. A sliding sleeve is movably mounted outside the opposing lead screw. The glass door is mounted at the bottom of the sliding sleeve. An oil storage box is mounted at the top of the sliding sleeve. A movable rod is threaded through the interior of the oil storage box. An elastic pad is mounted at the top of the movable rod. A valve plug is mounted at the bottom of the oil storage box.

[0007] Preferably, the output end of the servo motor is connected to the opposing lead screw drive.

[0008] Preferably, a through hole is provided between the oil reservoir and the sliding sleeve, and the valve plug extends into the through hole.

[0009] Preferably, one end of the movable rod passes through the oil storage box, and the bottom of the elastic pad abuts against the top of the oil storage box.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention achieves automatic lubricant supply through the cooperation of the oil reservoir, the movable rod, and the internal protrusions of the slide rail. This reduces the frequency and cost of manual maintenance, while continuous lubrication effectively reduces wear between the slide rail and the slide sleeve, extending the service life of the overall structure.

[0017] The following is combined with Figure 1-4 This application will be described in further detail.

[0018] An automatic sensor door telescopic structure includes a slide rail 1, a glass door 3, and an oil storage box 4. Three protrusions 101 are provided on both sides of the interior of the slide rail 1. A counteracting lead screw 201 is mounted inside the slide rail 1 via bearings. A servo motor 2 is provided on one side of the slide rail 1. A sliding sleeve 301 is movably mounted outside the counteracting lead screw 201. The glass door 3 is mounted at the bottom of the sliding sleeve 301, and the oil storage box 4 is mounted at the top of the sliding sleeve 301. A movable rod 401 is threaded through the interior of the oil storage box 4. An elastic pad 403 is mounted at the top of the movable rod 401, and a valve plug 402 is mounted at the bottom of the oil storage box 4.

[0019] Furthermore, the output end of the servo motor 2 is connected to the opposing lead screw 201 for transmission.

[0020] Furthermore, a through hole is provided between the oil storage box 4 and the sliding sleeve 301, and the valve plug 402 extends into the through hole.

[0021] Furthermore, one end of the movable rod 401 passes through the oil storage box 4, and the bottom of the elastic pad 403 abuts against the top of the oil storage box 4.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of the telescopic structure of an automatic sensor door in this application embodiment is as follows: The device drives the opposing lead screw 201 to rotate by the energization of the servo motor 2. The rotation of the opposing lead screw 201 can make the sliding sleeve 301 move on the opposing lead screw 201, so as to achieve precise control and smooth movement of the door. When the sliding sleeve 301 moves horizontally, the movable rod 401 moves to the position of the protrusion 101. Under the action of pressure, it pushes the valve plug 402 to sink and open, so that the lubricant in the oil storage box 4 automatically drips and penetrates to the friction surface between the opposing lead screw 201 and the sliding sleeve 301 to achieve continuous lubrication. When the movable rod 401 disengages from the protrusion 101, the movable rod 401 rebounds and resets under the action of the elastic pad 403.

[0024] The foregoing description of an exemplary embodiment of the telescopic structure of the automatic sensor door provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
