The telescopic sleeve is provided with a concession slot, and the concession slot is equipped with a limit block, a rotating shaft and a torsion spring. The position block is hinged in the relief groove through the rotating shaft, and the torsion spring exerts a force on the limit block, so that the limit groove and the limit protrusion cooperate with each other, and a part of the limit block extends out of the relief groove.

In the parking frame with adjustable length disclosed in this creation, the part of the limit block extending out of the relief groove is semi-cylindrical, and there are many ribs distributed around its circumference.

In the parking frame with adjustable length disclosed in this creation, the notch of the limit slot is gradually wider.

In the parking frame with adjustable length disclosed in this creation, the corners of the limit protrusions are rounded corners.

In the parking frame with adjustable length disclosed in this creation, the groove wall and the limit block of the relief groove are respectively provided with a clamping groove for the end of the torsion spring to be embedded.

In the parking frame with adjustable length disclosed in this creation, the middle of the telescopic sleeve is provided with a slot for inserting the foot post. The cross section of the slot is L-shaped, and the side of the foot post is extended with a guide part. The slots are matched to limit the relative movement of the foot post and the telescopic sleeve in the circumferential direction.

In the parking frame with adjustable length disclosed in this creation, the bottom of the telescopic sleeve is provided with a supporting plate, the bottom of the supporting plate is arranged obliquely, and the bottom of the supporting plate is provided with a plurality of anti-skid protrusions.

In the parking frame with adjustable length disclosed in this creation, the limit block is an integral structure.

In the parking frame with adjustable length disclosed in this creation, the rotating shaft is a bolt with a countersunk head, which is fixed to the relief slot by the bolt.

In this way, the adjustable-length parking frame of this creation includes the main frame body and the support rods. The rod includes a foot post and a telescopic sleeve. The upper end of the foot post is pivotally connected to the main frame. The foot post is arranged with a plurality of limit protrusions along its length. The telescopic sleeve is sleeved on the lower end of the foot post. The telescopic sleeve The tube is provided with a concession slot. The concession slot is equipped with a limit block, a rotating shaft and a torsion spring. The limit block is hinged in the concession slot through the rotating shaft. The torsion spring exerts a force on the limit block to make the limit slot and the limit stop. The protrusions cooperate with each other to limit the limit of the telescopic sleeve in the length direction. The part of the limit block extends out of the relief groove, which is convenient for outside operation. The limit block rotates. When the length of the support rod needs to be adjusted, the external force rotates the limit The position block separates the limit protrusion from the limit groove. Move the telescopic sleeve to the corresponding position. After the limit block is released, the limit groove is locked with other limit protrusions under the action of the torsion spring. The length adjustment is completed. Compared with the prior art, the parking frame of the invention has a simple and stable structure and convenient operation.

The creation will be described in detail below in conjunction with specific embodiments and drawings.

The length-adjustable parking frame of this embodiment, as shown in the first to fourth figures, includes a main frame body 1 and a support rod 2. The support rod 2 includes a foot post 21 and a telescopic sleeve 22, and the upper end of the foot post 21 The foot post 21 is pivotally connected to the main frame 1, and the foot post 21 is arranged with a plurality of limiting protrusions 211 along its length. The telescopic sleeve 22 is sleeved on the lower end of the foot post 21, and the telescopic sleeve 22 is provided with a pipe wall passing through it. The relief slot 221 is provided with a limiting block 23, a rotating shaft 24 and a torsion spring 25, and the limiting block 23 is hinged by the rotating shaft 24 In the relief groove 221, the torsion spring 25 exerts a force on the limit block 23, so that the limit groove 231 and the limit protrusion 211 cooperate with each other, thereby limiting the length of the telescopic sleeve 22 in the length direction, and the limit block The part of 23 extends to the outside of the relief groove 221 to facilitate the rotation of the limit block 23 for external operation. When the length of the support rod 2 needs to be adjusted, the limit block 23 is rotated by external force to separate the limit protrusion 211 from the limit slot 231, and the telescopic sleeve 22 is moved to the corresponding position.
