Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of connection structure between slider and rotating shaft, and in particular to a connection structure between a movable slider and a rotating shaft. Background Technology
[0002] The existing connection method between the central shaft and the slider on the balance easy-sliding door has the following drawbacks: the two flanges in the existing technology are connected by multiple screws, which occupies too much operating space and is very inconvenient to install; another existing technology is to lock the concave head shaft with screws on the slider connecting plate, which has the disadvantage of putting force on the shaft at a point, making it prone to loosening and shaft breakage.
[0003] Therefore, a new type of locking structure is urgently needed to solve the above problems. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a locking structure between a movable slider and a rotating shaft.
[0005] This utility model is achieved through the following technical solution: A locking structure for a movable slider and a rotating shaft includes a guide rail fixed upside down to the bottom of a movable plate, a slider on the guide rail, a retainer on the slider, a U-shaped opening facing inward and stepped in the middle of the retainer, a limit port on the inner wall of the U-shaped opening and a limit plate engaged in the limit port, and a T-shaped block capable of forward and backward displacement engaged in the U-shaped opening, the T-shaped block having a circular groove in its center; It also includes a base plate, which is fixedly connected to the bottom bushing, and the rotating shaft is rotatably connected to the bushing; the center of the limiting plate is provided with a through threaded hole, and the limiting screw passes through the threaded hole on the limiting plate and abuts against the circular groove on the T-block.
[0006] Furthermore, the back of the T-shaped block is stepped to fit the U-shaped opening and is arc-shaped, with the arc surface of the T-shaped block being a serrated surface.
[0007] Furthermore, the inner diameter of the serrated surface is adapted to the inner diameter of the U-shaped opening.
[0008] Furthermore, a shaft support is provided at the top of the rotating shaft, and the bottom surface of the shaft support abuts against the lower end face of the U-shaped opening and the T-shaped block.
[0009] The beneficial effects of this utility model are: This invention utilizes the rotational connection between the movable slider and the rotating shaft, which can effectively reduce the space occupied. At the same time, by tightening the limiting screw, the position of the T-block is limited, thereby determining the size of its opening with the U-shaped opening, so as to achieve the purpose of locking.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0013] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0014] like Figures 1 to 7 As shown, this utility model includes a guide rail 1 fixed upside down to the bottom of a movable plate. A slider 101 is provided on the guide rail 1 as a movable base. A card seat 2 is installed on the slider 101. The card seat 2 has an inwardly facing, stepped U-shaped opening 202 in the middle, which can serve as a locking and bottoming function. A limiting opening 203 is provided on the inner wall of the U-shaped opening 202, and a limiting plate 4 is locked in the limiting opening 203. A T-shaped block 3 capable of forward and backward displacement is locked in the U-shaped opening 202. A circular groove is provided in the center of the T-shaped block 3. It also includes a base plate 6, which is fixedly connected to a bushing 602 at the bottom, and the rotating shaft 601 is rotatably connected to the bushing 602.
[0015] The limiting plate 4 has a through threaded hole in the center. The limiting screw 5 passes through the threaded hole on the limiting plate 4 and abuts against the circular groove on the T-block 3. That is, by turning the limiting screw 5, the position of the T-block 3 is limited, thereby determining the size of its opening with the U-shaped opening 202, so as to achieve the purpose of locking.
[0016] The back of the T-block 3 is stepped to fit the U-shaped opening 202, ensuring that the contact surface is horizontal and arc-shaped. The arc surface of the T-block 3 is a sawtooth surface 301. The limiting screw 5 abuts against the shaft support 603 to lock and fix it.
[0017] The inner diameter of the serrated surface 301 is adapted to the inner diameter of the U-shaped opening 202.
[0018] The top of the rotating shaft 601 is provided with a shaft support 603, and the bottom surface of the shaft support 603 abuts against the lower end face of the U-shaped opening 202 and the T-shaped block 3.
[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
