[0002] The lift-and-slide door's lift-and-slide actuator is mounted on the side of the door and window, such as the lift-and-slide door lock actuator with a self-adjusting opening and closing force function disclosed in the patent with application number 201822135863.6, which includes a fixed plate and a slide plate, wherein the fixed plate is connected to the side of the door and window by screws, and the slide plate is provided with locking points, which are used to cooperate with the door frame to achieve locking. The conventional lift-and-slide door actuators on the market are 2400mm long (adapting to door leaf heights of 2000-2400), 2600mm (adapting to door leaf heights of 2400-2600), and 3000mm (adapting to door leaf heights of 2600-3000), and there are many models, which puts great pressure on dealers or customers to prepare stocks. Therefore, the utility model provides a lift-and-slide actuator extension rod, which can meet the requirements of more door leaf height specifications as long as a 2400mm long actuator is prepared and the lift-and-slide actuator extension rod described in this solution is added. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a lifting push-pull transmission extension rod, which has a simple structure and is combined with the original small-sized transmission to form a large-sized transmission to meet the requirements of multiple specifications in the market, thereby reducing the stocking pressure of dealers or customers.

[0005] According to the lifting and pushing and pulling transmission extension rod of the embodiment of the utility model, at least the following technical effects are achieved: the utility model can be used as an extension accessory of a door and window transmission with a length of 2400mm, so that the transmission increases in size to the same length specification as a transmission with a longer size specification; wherein the fixed rod is connected to the fixed plate part of the door and window transmission, and the moving rod is connected to the sliding plate part of the door and window transmission through the connecting head of the connecting rod, so that the sliding plate part and the moving rod can move synchronously, and the fixed plate part and the fixed rod remain relatively fixed; wherein the fixed rod can be connected to the side of the door and window through a connecting piece through the positioning hole, and the general connecting piece is a screw. In summary, since the utility model can use the fixed rod, the moving rod and the connecting rod as a whole to be used in conjunction with the door and window transmission, the door and window transmission with only a length of 2400mm can be increased to reach a long size specification, such as becoming 2600mm long, thereby eliminating the need for dealers or customers to prepare both a 2400mm long transmission and a 2600mm long transmission, and only a 2400mm long transmission is required. At the same time, since the utility model has one locking point, when the customer uses a 2400mm actuator with a standard configuration of 2 locking points, if the customer wants to increase the locking point to improve the sealing of the door, this extender can also be used to meet the requirement without replacing the 2600mm long actuator with 3 locking points.

[0006] According to some embodiments of the present utility model, the fixed rod is arranged vertically, and the first through groove is arranged at the bottom of the fixed rod.

[0007] According to some embodiments of the present invention, at least one positioning hole is provided at the lower portion of the first through groove.

[0008] According to some embodiments of the utility model, a locking screw is adapted to be arranged in the positioning hole, and the locking screw is threadedly connected to the side of the door or window.

[0010] According to some embodiments of the present invention, the second through groove is a waist-shaped hole.

[0011] In the above scheme, the locking screw passing through the positioning hole directly passes through the waist-shaped hole and then is connected to the side of the door and window. Since the movable rod needs to move, the second through groove needs to be made into a waist-shaped hole, so that the movable rod will not be stuck by the locking screw when it moves.

[0012] According to some embodiments of the present utility model, the locking point is fixed on the moving rod by a locking point fixing screw.

[0013] According to some embodiments of the utility model, a countersunk hole is provided on the connecting head, a countersunk screw is adapted to be provided in the countersunk hole, and the countersunk screw is connected to the door and window actuator.

The fixed rod 1 is provided with a first through groove 5 for the locking point 4 to pass through, and the length of the first through groove 5 is greater than the length of the locking point 4. A plurality of positioning holes 6 are provided on the fixed rod 1, and a second through groove 7 matched with the positioning holes 6 is provided on the movable rod 2. One end of the movable rod 2 is fixedly connected to one end of the connecting rod 3.

[0025] Specifically, the utility model can be used as an extension accessory of a door and window actuator 14 with a length of 2400mm, so as to increase its size and reach the same length specification as a longer size actuator; wherein, the fixed rod 1 is connected to the fixed plate part 15 of the door and window actuator 14, and the moving rod 2 is connected to the slide plate part 16 of the door and window actuator 14 through the connecting head 8 of the connecting rod 3, so that the slide plate part 16 and the moving rod 2 can move synchronously, and the fixed plate part 15 and the fixed rod 1 remain relatively fixed; wherein, the fixed rod 1 can be connected to the side of the door and window through a connecting piece through the positioning hole 6, and the connecting piece is generally a screw. In summary, since the utility model can use the fixed rod 1, the moving rod 2 and the connecting rod 3 as a whole to be used in combination with the door and window actuator 14, the door and window actuator 14 with a length of only 2400mm can be extended to reach a long size specification, such as becoming 2600mm long, thereby eliminating the need for dealers or customers to prepare both a 2400mm long actuator and a 2600mm long actuator, and only a 2400mm long actuator is needed. At the same time, since the utility model has a locking point 4, when the customer uses a 2400mm actuator with a standard configuration of 2 locking points, if the customer wants to increase the locking point to improve the sealing of the door, this extender can also be used to meet the requirements without replacing the 2600mm long actuator with 3 locking points. Of course, the length of the fixed rod 1 of the utility model can be designed to be optional, that is, the length also has two specifications, one specification and the door and window actuator 14 of the specification of 2400mm length are combined to form a specification of 2600mm length, and the other specification and the door and window actuator 14 of the specification of 2400mm length are combined to form a specification of 3000mm length. Therefore, dealers or customers only need to prepare a 2400mm long actuator, and add the combination of the utility model to meet the door leaf height of 2000-3000mm.

[0026] In some specific embodiments of the present invention, the fixed rod 1 is vertically arranged, and the first through slot 5 is arranged at the bottom of the fixed rod 1 .
