In use, the length adjustment assembly 10 is mounted on a drive link to form a portion of the drive link, and the overall length of the drive link is adjusted by adjusting the relative position between the slide rod 13 and the fixed rod 11. As shown in fig. 5, the rotary disc 12 is used to drive the sliding rod 13 to slide linearly on the fixed rod 11, and after the sliding rod 13 moves to a desired position, the rotary disc 12 is locked on the fixed rod 11 by the screw 14, so as to lock the position of the sliding rod 13.

The length adjustment assembly 10 described above is further described below with reference to fig. 1 to 5.

As shown in fig. 3, in the present embodiment, the fixed bar 11 is an elongated bar, and the material of the fixed bar is preferably metal, such as aluminum, stainless steel, or other alloy material. As shown in fig. 3, the fixed bar 11 is provided with a linear slide groove 111. The linear guide 111 is provided along the extending direction of the fixed bar 11.

As shown in fig. 3 and 4, the rotary plate 12 is pivoted to the fixed bar 11 and is provided with a driving pole 121 extending toward the linear chute 111. And, the carousel 12 is equipped with the drive part 122 that is used for driving carousel 12 to rotate apart from the one side of fixed rod 11. The turntable 12 is provided with an arc-shaped slot 123, and the arc-shaped slot 123 is arranged along the rotating direction of the turntable 12 and penetrates through the front and back sides of the turntable 12.

As shown in fig. 3, in the present embodiment, a rotating shaft 124 is provided on a surface of the rotating disk 12 facing the fixed bar 11, and the fixed bar 11 is provided with a shaft hole 112 for abutting against the rotating shaft 124. It is understood that the positions of the rotating shaft 124 and the shaft hole 112 can be adjusted, for example, in other embodiments, the shaft hole 112 is provided on the side of the rotating disc 12 facing the fixed bar 11, and the rotating shaft 124 abutting against the shaft hole 112 is provided on the fixed bar 11. The rotating shaft 124 and the shaft hole 112 can be used for realizing the pivoting connection between the rotating disc 12 and the fixed rod 11, and the structure is simple and stable.

As shown in fig. 1 and 3, in the present embodiment, the driving portion 122 is provided with a hexagonal hole corresponding to a hexagonal wrench, so that an operator can rotate the rotary disk 12 by inserting the hexagonal wrench into the hexagonal hole. In other embodiments, the driving portion 122 may be disposed in a cross hole, a straight hole, or a triangular hole. The turntable 12 can be driven to rotate by selecting a suitable tool to abut against the hole position on the driving portion 122.

It will be appreciated that abutments opposite the hole locations may also be used to effect abutment between the tool and the drive portion 122. In other embodiments, the driving portion 122 may be provided with one or more of a hexagonal pillar, a cross pillar, a straight pillar, and a triangular pillar. The turntable 12 can be driven to rotate by connecting a suitable tool to the post of the driving portion 122.

As shown in fig. 3, in the present embodiment, the slide bar 13 is provided in an elongated shape. The slide rod 13 is slidably connected to the linear slide groove 111 and has a notch 131 into which the driving pole 121 is inserted. The width of the notch 131 along the extending direction of the linear sliding chute 111 matches the width of the transmission pylon 121, and the width of the notch 131 along the extending direction perpendicular to the linear sliding chute 111 is greater than the width of the transmission pylon 121, so that when the rotary disc 12 rotates, the sliding rod 13 can be driven to move by the cooperation of the transmission pylon 121 and the notch 131 under the limitation of the linear sliding chute 111. As the rotary disk 12 rotates, the driving pylons 121 are also displaced in a direction perpendicular to the extending direction of the linear sliding grooves 111, and therefore, the slots 131 need to provide the driving pylons 121 with a moving space perpendicular to the extending direction of the linear sliding grooves 111.

Since the length adjustment of the transmission rod is a fine adjustment, i.e. the adjustment has a small amplitude, it is difficult for the operator to judge the adjustment amplitude visually when operating the length adjustment assembly 10. Therefore, as shown in fig. 1 and 3, in the present embodiment, the fixed link 11 is provided with the marking portion 113 disposed adjacent to the linear slide groove 111, and accordingly, the slide rod 13 is provided with the scale 132 disposed along the extending direction of the linear slide groove 111. For example, the mark part 113 may be a triangle symbol, and the scale 132 is provided with scale values from-5 to + 5. It is understood that in other embodiments, the positions of the scale 132 and the marking portion 113 can be reversed, for example, the fixed rod 11 is provided with the scale 132 along the linear sliding groove 111, and accordingly, the sliding rod 13 is provided with the marking portion 113. When the slide rod 13 is linearly displaced relative to the fixed rod 11, the position on the scale 132 pointed by the mark part 113 changes, so that the operator can intuitively know the displacement of the slide rod 13.

As shown in FIG. 3, the screw 14 has one end threaded through the arc-shaped slot 123 and connected to the fixed rod 11, and the head of the screw 14 abuts against the arc-shaped slot 123 of the rotary disk 12.

As shown in fig. 1 and 3, in the present embodiment, the head of the screw 14 is provided with an operation portion having the same structure as the driving portion 122, that is, the head of the screw 14 is also provided with a hexagonal hole, and the operation of the screw 14 can be performed by a hexagonal wrench. The screw 14 and the rotary disc 12 can be operated by the same tool, so that the difficulty of operation is simplified.

In addition, the arc-shaped groove 123 can be provided with an anti-slip thread 1231 in contact with the screw 14. The anti-slip pattern 1231 can improve the locking stability of the screw 14 and improve the positioning reliability of the turntable 12. For example, as shown in fig. 1 and fig. 3, in the present embodiment, a tooth-shaped line is provided at the periphery of the arc-shaped groove 123, and the friction coefficient can be increased by using the tooth-shaped line, so that the contact between the screw 14 and the rotary disk 12 is more stable and reliable.

Considering that the fixed link 11 needs to be mounted on one of the rods and the sliding link 13 needs to be mounted on the other rod of the transmission rod when the length adjustment assembly 10 is in use, in the present embodiment, as shown in fig. 2, the end of the fixed link 11 away from the sliding link 13 is provided with the first connection portion 114. One end of the sliding rod 13 far away from the fixed rod is provided with a second connecting part 133. The first connecting portion 114 can realize the quick connection between the fixed rod 11 and one of the transmission rods, and the second connecting portion 133 can realize the quick connection between the fixed rod 11 and the other of the transmission rods. Further, in the present embodiment, the first connection portion 114 is a bump structure and is provided with a connection hole. The second connecting portion 133 is a bump structure and has a protrusion.

As shown in fig. 5, when the relative position between the sliding rod 13 and the fixed rod 11 needs to be adjusted, the screw 14 is loosened, the driving portion 122 of the rotary disc 12 drives the rotary disc 12 to rotate, the screw 14 is avoided through the arc-shaped groove 123 in the rotating process of the rotary disc 12, the rotational motion of the rotary disc 12 is converted into the linear motion of the sliding rod 13 by utilizing the matching relationship between the transmission pillar stand 121 of the rotary disc 12 and the notch 131 on the sliding rod 13 and the limitation of the linear sliding groove 111, so that the sliding rod 13 generates the linear relative displacement with respect to the fixed rod 11. After the sliding rod 13 is moved to the desired position, the screw 14 is tightened to lock the rotary disk 12 to the fixed rod 11. Through the design, the rotary disc 12 is used for realizing conversion between rotary motion and linear motion, the adjusting mode of the length adjusting assembly 10 is converted into rotary operation, the adjustment does not need to be operated along the extending direction of the transmission rod, the stepless adjustment of the sliding rod 13 can be realized by rotating the rotary disc 12 in situ, even if the installation depth of the transmission rod in a door window is large, the operation can be easily performed, a linear gap for operation does not need to be reserved, the occupation of the part layout space of equipment is reduced, and the compact design is facilitated.
