Detailed ways

The embodiments of the present invention are described below by specific embodiments, and those who are familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

Please refer to Figure 1 to Figure 4. It should be noted that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", " The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that is usually placed when the utility model product is used, only for the convenience of describing the present utility model and simplifying the description, Rather than indicating or implying that the indicated device or element must have a particular orientation, be constructed and operate in a particular orientation, it should not be construed as a limitation of the present invention. Furthermore, the terms "first", "second", "third", etc. are only used to differentiate the descriptions and should not be construed to indicate or imply relative importance. The terms "horizontal", "vertical", "overhanging" etc. do not imply that a component is required to be absolutely horizontal or overhang, but rather may be slightly inclined. For example, "horizontal" simply means that its direction is more horizontal than "vertical", it does not mean that the structure must be completely horizontal, but can be slightly inclined.

In the description of the present invention, it should also be noted that, unless otherwise expressly specified and limited, the terms "arrangement", "installation", "connection" and "connection" should be understood in a broad sense, for example, it may be a fixed connection It can also be a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or an internal connection between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

Example: As shown in Figures 1 to 4, a track 1 docking lock structure for an overhead rail shifter includes a track 1, and a pulley assembly 2 is movably arranged in the track 1; The top of the end is provided with a docking lock; the docking lock includes a firmware component 3, and a sliding component 4 is provided on the fixed component that can be translated back and forth, and the front end of the sliding component 4 is provided with a protruding track 1. The transmission assembly, the sliding assembly 4 is connected with the swing rod 5 through the pin, the swing rod 5 is rotatably arranged above the track 1, the bottom of the swing rod 5 is provided with a limit block 6, and the pulley block The top of the component 2 is provided with a convex block 7 corresponding to the limit block 6; a reset mechanism is provided on the fixed component, and the reset mechanism includes a reset spring 8, and the movable component is fixedly provided with the reset spring. 8 corresponds to putter 9. A rail 1 docking lock structure designed in this scheme is used for the overhead rail lift. The sliding component 4 slides back and forth to drive the pendulum rod 5 to rotate, so as to limit the position of the pulley in the rail 1 and avoid the rail 1 before docking. When the pulley assembly 2 slides out from the end of the track 1 and is separated from the track 1, the specific working principle is as follows: As shown in Figure 1, when the track 1 is not docked, in the initial state, the transmission assembly at the front end of the sliding assembly 4 protrudes from the track 1. At the outer edge of the end, the limit block 6 at the lower end of the pendulum rod 5 protrudes above the track 1, and the limit block 6 can clamp the bump 7 above the pulley assembly 2 to ensure that the pulley assembly 2 will not pass from the end of the track 1. Detach the track 1; when the two tracks 1 are butted, the front end of the sliding component 4 protruding from the outside of the track 1 is squeezed by the other track 1, and will retract into the track 1 after being stressed, and the sliding component 4 as a whole will Translate backward, so as to rotate upward with the pendulum rod 5. The upward rotation of the pendulum rod 5 will cause the limit block 6 at the end to rise. At this time, the pulley assembly 2 is no longer blocked by the limit block 6, and can be docked on the track 1. After completion, it is smoothly transferred to the inside of the other track 1; when the two tracks 1 are docked, the sliding assembly 4 moves backwards to make the push rod 9 at the bottom squeeze the spring, and when the track 1 completes the docking and begins to separate, the sliding assembly 4 4. The transmission assembly at the front end is no longer subjected to the pressing force, and the rebound force of the spring will make the sliding assembly 4 move forward, so as to reset the docking lock.

The preferred embodiment is as follows:

As shown in FIGS. 1 and 2 , a panel 10 is provided at the end of the track 1 , a stopper 11 is fixed on the inner side of the panel 10 , and the front end of the swing rod 5 is provided with a card corresponding to the stopper 11 . At the same time, a limit hole 13 is formed on the swing rod 5, and a limit rod 14 inserted into the limit hole 13 is provided on the fixed component, and the hole diameter of the limit hole 13 is larger than the limit Lever 14; in order to prevent the bump 7 on the pulley assembly 2 from squeezing the limit block 6 on the swing lever 5 to make the swing lever 5 rotate upward and make the entire docking lock fail, a card slot 12 is provided at the front end of the swing lever 5, After the stopper 11 on the panel 10 is engaged with the card slot 12, it can limit the pendulum rod 5; at the same time, in order to ensure that the pendulum rod 5 will not be docked due to the inability of the card slot 12 and the stopper 11 to rotate upward when unlocked. The lock fails, so the matching structure of the limit hole 13 and the limit rod 14 is provided, so that the pendulum rod 5 can achieve a small range of front and rear translation under the premise of flipping, so the running track of the pendulum rod 5 is: when the sliding component 4 moves to When moving backwards, the pendulum rod 5 first moves back for a short distance to separate the card slot 12 and the stopper 11, and then flips up; Then move forward a short distance so that the stopper 11 and the card slot 12 are engaged with each other.

As shown in FIG. 4 , the transmission assembly is specifically a roller 15, and the roller 15 is rotatably arranged at the front end of the sliding assembly 4 through a pin shaft; the roller 15 can reduce the distance between the front end portion and the end portion of the other rail 1 The friction force when contacting, so that the two rails 1 are more smooth when docking.

As shown in FIG. 3 , the sliding assembly 4 is provided with a raised movable rod 16 , the fixed assembly is provided with a chute 17 , and the movable rod 16 is movably arranged inside the chute 17 ; The movement of the rod 16 in the chute 17 can limit the sliding component 4, and the sliding component 4 can stop moving after moving forward or backward to a certain distance.

The above-mentioned embodiments merely illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Anyone skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
