[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a hardware linkage that can be used in electric retractable gates. It uses a collar to block the first link and the second link from contacting the locking pin, so as to avoid damage to the locking pin. It also reduces the wear of the first link and the second link caused by friction through the rolling of the ball.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hardware linkage that can be used in electric retractable gates includes a first linkage and a second linkage, wherein the first linkage and the second linkage are rotatably connected by a connecting rod; Both ends of the connecting rod are fitted with collars, and multiple balls are evenly distributed circumferentially on the opposite side of the two collars. A limiting sleeve is fixedly installed on the outer side of the collar, and both ends of the connecting rod are provided with fixing components for fixing the limiting sleeve.

[0005] Preferably, the fixing component includes a square rod fixedly installed on the end of the connecting rod, and the side wall of the square rod is symmetrically provided with two pin holes, and a locking pin is inserted into both pin holes.

[0006] Preferably, the locking pin has a right-angled U-shaped structure.

[0007] Preferably, the outer side of the limiting sleeve is threaded with a protective cover.

[0008] Preferably, the inner hole of the limiting sleeve is square, and the outer side is circular.

[0009] Preferably, the protective cover is made of plastic.

[0010] This utility model has the following beneficial effects: 1. Through the design of ball bearings and collars, the rolling of the ball bearings reduces the wear of the first and second connecting rods caused by friction, and also avoids the wear of the retaining pin, effectively ensuring the normal use of the retaining pin; 2. Through the design of the fixing component, the retaining pin is inserted into the pin hole to fix the limiting sleeve, thereby fixing the collar and making the ball contact the first connecting rod and the second connecting rod, preventing the retaining pin from contacting them; 3. The protective cover design serves a protective function, preventing damage to the locking pin and thus avoiding slippage of the connecting rod. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] Reference Figures 1-3A hardware linkage that can be used in electric retractable gates includes a first linkage 1 and a second linkage 2, which are rotatably connected by a connecting rod 6. Both ends of the connecting rod 6 are fitted with collars 3. On the opposite side of the two collars 3, there are multiple balls 5 evenly spaced in the circumference. A limiting sleeve 7 is fixedly installed on the outside of the collars 3. The inner hole of the limiting sleeve 7 is square and the outer side is circular. Both ends of the connecting rod 6 are provided with fixing components for fixing the limiting sleeve 7. The fixing components include a square rod 9 fixedly installed on the end of the connecting rod 6. The side wall of the square rod 9 is symmetrically provided with two pin holes 10. A locking pin 8 is inserted into both pin holes 10. The locking pin 8 is a right-angled U-shaped structure. The two ends of the connecting rod 6 are locked by the locking pin 8. The first connecting rod 1 and the second connecting rod 2, which are intersecting each other, will not fall off from one end of the connecting rod 6, thus ensuring the safe operation of the electric retractable gate. The outer threaded connection of the limiting sleeve 7 is equipped with a protective cover 4. The protective cover 4 is made of plastic and serves as a protective measure to prevent the locking pin 8 from being damaged, which would cause the connecting rod 6 to slip off.

[0016] Working principle: During installation, the collar 3 is placed on the end of the connecting rod 6, and the limiting sleeve 7 is placed on the square rod 9 to prevent the collar 3 from moving further toward the connecting rod 6. Then, the locking pin 8 is inserted into the pin hole 10 to position the limiting sleeve 7, thus fixing the collar 3. During the retraction and extension of the door, the first link 1 and the second link 2 come into contact with the ball bearing 5. The rolling of the ball bearing 5 reduces friction and avoids friction with the locking pin 8, effectively ensuring the normal use of the locking pin 8.
