Through setting up fixed cover 330, at first the second direction through-hole can with the regulation hole combined action, the reinforcing is to the guide effect of the box 400 at the middle part of the screen body 100, moreover because the underframe thickness of box 400 is limited, and the bottom plate 120 thickness of the screen body 100 is limited promptly, has consequently set up fixed cover 330 and has made the area that the regulation post 320 is located to wear to establish great, and fixed cover 330 cover is established on adjusting post 320 promptly for box 400 can not take place the slope at the in-process of going up and down. In one embodiment, the fixing sleeve 330 is fixedly connected to a surface of the base plate 120 away from the receiving portion 310, so that the fixing sleeve 330 is firmly connected to the base plate 120, and the box 400 is less prone to tilt during the lifting process. In one embodiment, the sidewall of the second guiding through hole is provided with a second internal thread, and the second internal thread is matched with the first external thread 321, so that the adjusting post 320 can rotate relative to the fixing sleeve 330, even if the fixing sleeve 330 is lifted up and down along with the base plate 120.
In order to adjust the height of the two ends of the bottom of the screen body 100 conveniently, in one embodiment, the receiving portion 310 is provided with a threaded mounting hole, one end of the adjusting column 320 is located in the threaded mounting hole and is in threaded connection with the side wall of the threaded mounting hole, so that the height of a certain end of the bottom of the screen body 100 can be achieved by rotating the adjusting column 320 without lifting the bottom of the screen body 100, and the operation is simpler and more labor-saving.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
