Referring to fig. 1 to 3, a length adjustment structure 10 according to an embodiment of the present invention includes a connection assembly 100, an elastic member 200, an adjustment member 300, and a locking member 400. The connecting assembly 100 includes a fixed rod 110 and a sliding rod 120, and the elastic member 200, the adjusting member 300 and the locking member 400 are connected between the fixed rod 110 and the sliding rod 120, and cooperate to realize the relative movement between the fixed rod 110 and the sliding rod 120, thereby extending or shortening the length of the connecting assembly 100.

Specifically, the slide bar 120 is formed with an inclined surface 121. Both ends of the elastic member 200 are respectively connected to the fixed bar 110 and the sliding bar 120, and the elastic member 200 can apply an elastic force to the sliding bar 120 along a first direction. The adjusting member 300 is disposed on the fixed rod 110, and the adjusting member 300 can abut against the inclined surface 121 and apply a pressing force to the inclined surface 121 in a direction opposite to the first direction. When the pressing force of the adjusting member 300 is greater than the elastic force of the elastic member 200, the slide rod 120 can move in a direction opposite to the first direction with respect to the fixed rod 110; when the pressing force of the adjusting member 300 is smaller than the elastic force of the elastic member 200, the elastic member 200 can force the sliding rod 120 to move in a first direction relative to the fixed rod 110, so that the sliding rod 120 and the fixed rod 110 move in two opposite directions, thereby extending or shortening the overall length of the connecting assembly 100. In addition, when the length of the connecting assembly 100 is adjusted to a certain position, the fixed bar 110 and the sliding bar 120 may be locked by the locking member 400.

Thus, in the length adjustment structure 10, the sliding rod 120 can move relative to the fixed rod 110 only by adjusting the adjusting member 300, so that the length of the connecting assembly 100 can be changed within a certain range, and the length adjustment structure is simple and convenient to operate and high in adjustment precision.

Specifically, the adjusting member 300 is a socket head cap screw, and is screwed with the first threaded hole 112. When the adjusting member 300 is rotated and the length of the adjusting member 300 extending into the accommodating space 111 is increased, the adjusting member 300 applies a pressing force to the inclined surface 121 and forces the slide bar 120 to move in the reverse direction of the first direction; when the adjusting member 300 is rotated reversely and the length of the adjusting member 300 extending into the accommodating space 111 is reduced, the sliding rod 120 is pushed to move in the first direction by the elasticity of the elastic member 200.

Specifically, one end of the adjusting member 300 abutting against the inclined surface 121 is a conical surface, so that the tip of the adjusting member 300 has a smaller contact area with the inclined surface 121, and thus has a smaller frictional resistance, thereby improving the smoothness of the tip of the adjusting member 300 moving along the inclined surface 121 when the sliding rod 120 moves relative to the fixed rod 110.

Specifically, a limiting groove 122 is formed at one end of the sliding rod 120 extending into the accommodating space 111, one end of the elastic member 200 is accommodated in the limiting groove 122, and the other end of the elastic member contacts with an inner wall surface of the fixed rod 110. The limiting groove 122 can limit the elastic member 200, and prevent the elastic member 200 from changing its position between the sliding rod 120 and the fixed rod 110.

In an embodiment, the elastic member 200 is a spring, one end of which abuts against the limiting groove 122, and the other end of which abuts against the inner wall surface of the fixed bar 110, so as to apply an elastic force to the sliding bar 120 to force the sliding bar 120 to move away from the fixed bar 110, at this time, the inclined surface 121 is disposed opposite to the elastic member 200 and toward the adjusting member 300, so that the adjusting member 300 can apply a pressing force opposite to the first direction to the inclined surface 121. Specifically, the adjusting member 300 is disposed in a direction perpendicular to the first direction so as to be exposed after the integrated structure is mounted on the door/window body, thereby facilitating manual adjustment. In other embodiments, the adjuster 300 may also be disposed in a direction parallel to the first direction. As shown in fig. 3, the direction indicated by the arrow is the first direction.

In another embodiment, the elastic member 200 may be a tension spring, one end of which is connected to the sliding rod 120 and the other end of which is connected to the inner wall surface of the fixed bar 110, so as to apply an elastic force to the sliding rod 120 to force the sliding rod 120 to approach the fixed bar 110, and at this time, the inclined surface 121 is disposed toward the elastic member 200 and the adjusting member 300, so that the adjusting member 300 can apply a pressing force to the inclined surface 121 opposite to the first direction.

Specifically, the sliding rod 120 is provided with a receiving groove 123, and the inclined surface 121 is formed in the receiving groove 123. The edge of the receiving groove 123 can play a supporting role when the sliding rod 120 moves in the receiving space 111, so that the movement of the sliding rod 120 is relatively smooth. In addition, the part of the adjusting member 300 extending into the receiving slot 123 can also limit the sliding rod 120, so as to prevent the sliding rod 120 from coming out of the receiving space 111 and completely separating from the fixed rod 110. Further, the accommodating groove 123 extends on a side away from the adjusting member 300 and penetrates through the sliding rod 120, so as to play a role of avoiding in the process of machining the inclined surface 121.

In addition, the fixed rod 110 is provided with an adjusting mark around the first threaded hole 112 to mark the rotating direction of the adjusting member 300, for example, the direction of the arrow pointing to "+" indicates that the adjusting member 300 is rotated, the length of the adjusting member 300 screwed into the accommodating space 111 is increased, the direction of the arrow pointing to "-" indicates that the adjusting member 300 is rotated, and the length of the adjusting member 300 screwed into the accommodating space 111 is decreased.

Specifically, the fixed rod 110 includes a first end 113, a second end 114 and a middle section 115 connected between the first end 113 and the second end 114, and the first end 113, the second end 114 and the middle section 115 cooperate to make the fixed rod 110 have a zigzag structure. The receiving space 111 is located at the middle section 115 and is disposed to penetrate the second end 114, and the locking member 400 is disposed at the second end 114. In this way, one end of the sliding rod 120 can extend into the accommodating space 111 from the side of the middle section 115 where the second end 114 is connected, and can slide relative to the fixed rod 110.

Furthermore, the fixed rod 110 is provided with a waist-shaped hole 116 extending along the first direction, the sliding rod 120 is provided with a second threaded hole 124, the locking member 400 comprises a connecting rod 410 and a cap end 420 connected to one end of the connecting rod 410, the connecting rod 410 penetrates through the waist-shaped hole 116 and is screwed with the second threaded hole 124, and the cap end 420 presses the fixed rod 110 at the edge of the waist-shaped hole 116. After the adjusting member 300 adjusts the length of the connecting assembly 100 to a desired position, the locking member 400 is tightened to press the cap end 420 against the fixed bar 110, thereby locking the sliding bar 120 to the fixed bar 110. Further, the connecting rod 410 can move in the kidney-shaped hole 116 to change positions to match with the second threaded hole 124 when the sliding rod 120 moves relative to the fixed rod 110. Specifically, the locking member 400 is a socket head cap screw.

The sliding rod 120 is formed with a first tooth-shaped structure 125 uniformly arranged along a first direction, and the fixed rod 110 is formed with a second tooth-shaped structure 117 engaged with the first tooth-shaped structure 125. After the sliding rod 120 moves to the proper position relative to the fixed rod 110, the first tooth-shaped structure 125 is engaged with the second tooth-shaped structure 117, and then the locking member 400 is locked, so that the sliding rod 120 is prevented from moving relative to the fixed rod 110 during the locking process of the locking member 400, and the relative movement of the sliding rod 120 and the fixed rod 110 is locked in the first direction, thereby achieving the sufficient locking between the sliding rod 120 and the fixed rod 110.

In addition, the sliding rod 120 is provided with a plurality of scale marks 126 uniformly distributed along the first direction. Specifically, the scale mark 126 is located on the slide bar 120 at a position corresponding to the second end 114, and the moving distance of the slide bar 120 can be measured by looking at the scale mark 126 exposing the second end 114 during the movement of the slide bar 120 relative to the fixed bar 110.
