[0022] One end of the top spring 38 away from the slide rod 35 is fixedly connected to a positioning plate 37, the outer wall of the positioning plate 37 is fixedly connected to the outer wall of the main rod body 32, the inner wall of the main rod body 32 is slidably connected to the outer wall of the slide rod 35, an oblique groove is opened in the wall of the main rod body 32 to facilitate the sliding of the slide rod 35, the outer wall of the slide block 36 is slidably connected to the inner wall of the fixed frame 1 through the slide groove 2, and the slide groove 2 is opened in the wall of the fixed frame 1, the locking assembly 5 includes a fixed block 51, the inner wall of the fixed block 51 is slidably connected to the plug block 52, and the outer wall of the plug block 52 is fixedly connected to the spring 54.
[0023] One end of the spring 54 away from the plug block 52 is fixedly connected to a fixing plate 53. The outer wall of the plug block 52 is slidably connected to the inner wall of the limiting column 7. The position of the limiting column 7 is limited by sliding the plug block 52 into the wall of the limiting column 7. The outer wall of the fixing plate 53 is fixedly connected to the outer wall of the fixing block 51, and the outer wall of the fixing block 51 is fixedly connected to the outer wall of the fixing tube 8.
[0024] Working principle:
[0025] When in use, it is only necessary to grasp the fixed tubes 8 on both sides of the cross bar 4 and lift them upwards to unfold the foldable movable frame. During the unfolding process, the folding component 3 is used to limit the position of the fixed tube 8. After the fixed tube 8 slides to the desired position, the locking component 5 can be used to release the lock of the limit column 7, and then the limit column 7 is slid out of the limit rod 6, and then the cross bar 4 is pulled to make the limit rod 6 slide out along the fixed tube 8. After the cross bar 4 slides to the desired position, it is only necessary to keep the locking component 5 in the unlocked state, and then the limit column 7 is re-passed through the fixed tube 8 and slid into the limit rod 6 to expand the use area of the movable frame.
[0026] Because the lifting ear 31 is fixed on the fixed tube 8, when the fixed tube 8 is lifted, the lifting ear 31 synchronously drives the main rod body 32 and the auxiliary rod body 33 to rise synchronously, because the sliding bar 35 on the main rod body 32 slides in the groove on the limiting plate 34, and the groove on the limiting plate 34 only allows the sliding bar 35 to slide in the direction of the auxiliary rod body 33, thereby preventing the fixed tube 8 from sliding downward, and a top spring 38 is connected between the sliding bar 35 and the positioning plate 37. Through the push of the top spring 38, the sliding bar 35 has the force to slide downward, and the slider 36 is used to slide in the sliding groove 2 on the fixed frame 1, thereby limiting the expansion position of the fixed tube 8.
[0027] When using the locking assembly 5, it is only necessary to apply a force to the insert block 52 on the fixed block 51 in the sliding direction of the fixed plate 53, so that the insert block 52 slides out of the limiting column 7, thereby releasing the lock on the limiting column 7. When the limiting column 7 needs to be locked again, it is only necessary to release the force on the insert block 52, and the elastic potential energy is released by the spring 54, so as to push the insert block 52 to slide back into the limiting column 7.
[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
