DETAILED DESCRIPTION

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0018] The utility model relates to a kind of length of car cross bar of convenient adjustment, such as Figures 1-5As shown, the device includes a first crossbar 1, inside which a second crossbar 2 is fitted. The second crossbar 2 can move within the first crossbar 1 to adjust its length. A first fixing seat 3 for fixing is fixedly connected to the bottom of the second crossbar 2, and a second fixing seat 4 for fixing is fixed to the bottom of the first crossbar 1. The crossbar is fixed to the roof bracket by the first fixing seat 3 and the second fixing seat 4. A slot 6 for limiting the movement is provided on one side of the second crossbar 2, and an observation port 7 for observation is provided on one side of the first crossbar 1 opposite to the slot 6, so as to facilitate observation of the movement position of the second crossbar 2 and avoid excessive movement that may cause it to fall off. An adjustment component 5 is provided at the bottom of the first crossbar 1 for adjusting the position of the first crossbar 1 and the second crossbar 2, and the adjustment component 5 is used to limit the movement distance of the second crossbar 2 on the first crossbar 1.

[0019] Among them, such as Figure 5 As shown, the adjusting component 5 includes a support plate 51, a locking pin 52 is movably connected to the upper part of the support plate 51, a limiting plate 55 is fixedly connected to the outer wall of the locking pin 52 to limit the movement position of the locking pin 52, a spring 54 is provided on the outer wall of the locking pin 52 between the limiting plate 55 and the support plate 51 to provide elasticity, the limiting plate 55 is connected to the support plate 51 through the spring 54, a baffle 56 is fixedly connected to the top of the first crossbar 1, the locking pin 52 passes through the support plate 51 and the baffle 56 and is fixedly connected to the fixed disc 53, a pulling frame 57 is fixedly connected to the outer wall of the limiting plate 55, the pulling frame 57 is symmetrically arranged on both sides of the limiting plate 55 about the baffle 56, when the pulling frame 57 is pulled, the limiting plate 55 drives the locking pin 52 to pass through the observation port 7 and insert into the slot 6 to lock the position of the first crossbar 1 and the second crossbar 2, the movement direction of the pulling frame 57 is parallel to the movement direction of the locking pin 52.

[0020] In practical use: The operator holds the pull frame 57 and pulls it to move the limiting plate 55 and the locking post 52. At the same time, the spring 54 set on the outer wall of the locking post 52 between the limiting plate 55 and the support plate 51 will extend and retract, and the locking post 52 will disengage from the slot 6. At this time, the second crossbar 2, which is sleeved inside the first crossbar 1, is pulled to move and adjust. When the pull frame 57 is released, the limiting plate 55, due to the elasticity of the spring 54, causes the locking post 52 to pass through the baffle 56 and the observation port 7 and insert into the slot 6, thus completing the locking of the positions of the first crossbar 1 and the second crossbar 2.
