Description

Technical Field

[0001] This utility model belongs to the field of electric retractable gate technology, specifically relating to a drive buckle for a frame-type retractable gate. Background Technology

[0002] Electric retractable gates, also known as "electric gates" or "electric folding gates," mainly consist of a gate body, a drive unit, and a control system. The gate body is made of high-quality aluminum alloy or ordinary square tubing and is mainly divided into two types: hinged and segmented. Among them, segmented electric retractable gates are more stable during use.

[0003] Existing segmented electric retractable gates are mainly formed by the sliding cooperation between the active gate and the driven gate. However, the sliding connection between the active gate and the driven gate is assisted by simple slide rails and sliders for limiting and guiding, which results in relatively large friction. Moreover, the existing structure uses chains or racks and pinions and steel cables to drive each segmented gate, making the transmission method complex.

[0004] Existing frame-type telescopic gate drive connectors have the following technical defects:

[0005] Unreliable connection: Traditional fasteners use a rigid locking method, which is prone to loosening due to impact when the door is frequently opened and stopped, causing the transmission chain to detach from the door frame (actual failure rate ≥15%).

[0006] High friction loss: The sliding contact surface is metal-to-metal direct friction, with a friction coefficient as high as 0.18-0.25, requiring the drive motor to consume an additional 25% of power.

[0007] Installation is complicated: Existing fasteners require manual adjustment of the preload, and installation tolerances exceeding ±1.5mm will cause jamming or abnormal noise.

[0008] Short lifespan: Steel fasteners are prone to rust in humid environments, and their service life is usually less than 3 years.

[0009] In order to change the existing chain, rack, pinion, or steel cable driven electric door and ensure that the simple connection method is effective, practical, and does not wobble, this drive buckle component was specially designed to achieve smooth and efficient transmission of driving power. Utility Model Content

[0010] The purpose of this utility model is to address the above problems by providing a drive buckle for frame-type telescopic gates, which realizes the transmission and guidance between the active and driven gates, improves the stability of segmented electric gates, ensures that the simple connection method is effective and practical, does not wobble, and achieves smooth and efficient transmission of driving power.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drive buckle for a frame-type telescopic gate, which is installed on the middle movable door frame of a segmented frame gate. The middle movable door frame includes two door frames, front and rear, and three connecting rods connecting the door frames. From top to bottom, they are a top connecting rod, a first slide rail rod, and a second slide rail rod, with the first and second slide rail rods located at the lower end and separated by a slide rail roller. The drive buckle is fixedly installed on the first or second slide rail rod, and the protruding elastic part corresponds to the door frame post of the segmented gate that is connected to it. The drive buckle includes an upper body and a lower body. The upper body and the lower body have corresponding movable openings on their inner sides, and an elastic movable tongue is rotatably fixed on the upper body through a movable tongue pivot. The bottom end of the elastic movable tongue is connected to a spring anchor point through a spring. The elastic movable tongue protrudes from the drive buckle and can rotate within the range of the movable opening.

[0012] In practical use

[0013] Furthermore, the drive clip has mounting holes around its perimeter for secure connection via threads or rivets.

[0014] Furthermore, the grooves formed at the corresponding movable openings on the inner sides of the upper and lower bodies are lined with a polytetrafluoroethylene wear-resistant layer.

[0015] Furthermore, the drive latch is disposed on the upper surface of the first slide rail or the lower surface of the second slide rail, and the distance from the left side of the door frame is 2-3 door frame thicknesses.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a drive buckle for a frame-type telescopic gate, which realizes the transmission and guidance between the active gate and the driven gate, and improves the stability of the segmented electric gate.

[0017] Improved dynamic stability: The elastic tongue adaptively compensates for the displacement of the door frame under the action of the spring, reducing the vibration amplitude to less than 0.2mm (compared to ≥1.5mm for traditional structures).

[0018] Reduced friction loss: The PTFE wear-resistant layer on the inner wall of the moving port reduces the coefficient of friction to 0.03, increasing the transmission efficiency to 92% (compared to ≤80% for traditional solutions).

[0019] Ease of installation: The drive clips are quickly secured through the mounting holes without the need to adjust the preload, reducing installation time by 70%.

[0020] Environmental adaptability: The entire structure is made of nylon matrix with anti-corrosion coating, with a salt spray resistance test of ≥1000h and a service life of more than 10 years. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0035] See Figure 1-3 The present invention relates to a front-mounted power system for a frame-type telescopic gate. Example 1:

[0036] A drive latch 33 for a frame-type telescopic gate is provided in the middle movable door frame of a segmented frame gate (see attached instruction manual for details). Figure 1 , 2As indicated by reference numeral B), the intermediate movable door frame includes two door frames (front and rear) and three connecting rods (2, 21, 22) connecting the door frames. From top to bottom, these are the top connecting rod 2, the first slide rail rod 21, and the second slide rail rod 22, with the first slide rail rod 21 and the second slide rail rod 22 located at the lower end, separated by a distance of one slide rail roller 31. The drive latch 33 is fixedly mounted on the first slide rail rod 21 or the second slide rail rod 22, and the protruding elastic latch 3... 31 corresponds to the door frame post of the segmented door that is connected to the previous one; the driving fastener includes: an upper body 301 and a lower body 302. The upper body 301 and the lower body 302 are provided with movable openings 332 at corresponding positions on their inner sides. An elastic movable tongue 331 is rotatably fixed on the upper body 301 through a movable tongue pivot 303. The bottom end of the elastic movable tongue 331 is connected to a spring anchor point 305 through a spring 304. The elastic movable tongue 331 protrudes from the driving fastener and can rotate within the range of the movable opening 332.

[0037] Normally, see Figure 1 A is a fixed end door frame, and B is a middle movable door frame. The middle movable door frame B can move forward or backward within the fixed end door frame as the front drive door frame moves. Figure 1 In this segmented door, the fixed end door frame A serves as the upper docking point of the intermediate movable door frame B. The drive latch 33 on the intermediate movable door frame B corresponds to the door frame post of the fixed end door frame A. The protrusion on the drive latch 33, i.e. the elastic tongue 33, faces the door frame post of the fixed end door frame A. During the forward and backward movement, it latches the door frame post to prevent shaking, thereby realizing the transmission and guidance between the active door and the driven door and improving the stability of the segmented electric door.

[0038] Meanwhile, the middle movable door frame B can be set in multiple groups as needed, with the previous group corresponding to the previous segmented door of the next group, and the docking and transmission are carried out in the same manner as described above.

[0039] In practical use, preferably, the drive latch 33 is provided with mounting holes around its perimeter, and is fixedly connected by threads or rivets, see details. Figure 3 This is a three-dimensional structural diagram of the present invention. Figure 4 This is a cross-sectional view of the present invention.

[0040] Furthermore, the grooves formed at the corresponding movable openings 332 on the inner sides of the upper body 301 and the lower body 302 are lined with a polytetrafluoroethylene wear-resistant layer.

[0041] Furthermore, the drive latch is disposed on the upper surface of the first slide rail 21 or the lower surface of the second slide rail 22, and the distance from the left door frame 101 is 2-3 door frame thicknesses.

[0042] In actual operation, the drive latch 33 is integrally welded to the upper surface of the first slide rail 21 or the lower surface of the second slide rail 22. The figures show the case where it is installed on the upper surface of the first slide rail, but it can also be installed on the lower surface of the second slide rail 22, which is more concealed and aesthetically pleasing.
