Description

Technical Field

[0001] The utility model relates to the field of poster racks, in particular to a poster rack that can be raised and lowered and can be stopped at will. Background Art

[0002] Poster stands are widely used in shopping malls, exhibition halls, airports, banks, post offices, hotels and other places. They play a role in conveying important information, reminding precautions, and promoting information dissemination. The most common poster stands on the market cannot control the height of the picture, the size of the picture, or the tilt angle of the picture, resulting in low product availability and single function. In addition, there are some poster stands on the market that can adjust the height and tilt angle of the picture. However, they all use mechanical structures, requiring users to manually open the fixings first, adjust the angle and height, and then manually fix the fixings. They cannot be operated with one hand and are inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model will be described in detail below with reference to the accompanying drawings:

[0031] Example: As attached Figures 1 to 14 As shown, the arbitrarily stop liftable poster stand comprises a support column 100, a lift gas support 200, an arbitrarily stop hinge 300, a telescopic placement frame 400, a cover plate 101, a nut 102, a mounting base 103, a lower fixing screw 201, an upper fixing screw 202, a connecting sleeve 301, a fixing plate 302, a rotating pin 303, a connecting hole 304, a first fixing hole 305, a second fixing hole 306, a third fixing hole 307, a connecting seat 308, a first screw 309, a second screw 310, a third screw 311, an upper inner Tube assembly 401, outer tube 402, lower inner tube assembly 403, lower hand screw 404, upper hand screw 405, support frame 4010, first baffle plate 4011, second baffle plate 4012, connecting plate 4013, first connecting screw 4014, second connecting screw 4015, inner tube 4016, hand screw hole 4017, first connecting screw hole 4018, second connecting screw hole 4019, upper slide groove 4020, first screw hole 4021, second screw hole 4022, third screw hole 4023 and lower slide groove 4024.

[0032] Reference Figure 1The bottom of the support column 100 is connected to the mounting base 103 by bolts, the lower end of the lifting gas support 200 is connected to the top of the support column 100, and the upper end of the lifting gas support 200 is hinged to the telescopic placement frame 400 through an arbitrary stop hinge 300. The telescopic placement frame 400 is used to place posters. The height of the poster relative to the mounting base 103 is adjusted by the lifting gas support 200, and the inclination of the poster is adjusted by the arbitrary stop hinge 300. The lifting gas support 200 (i.e., gas spring) adopts a conventional structure that can be purchased on the market, and the arbitrary stop hinge 300 also adopts a conventional structure that can be purchased on the market. The specific structure and working principle of the lifting gas support 200 and the arbitrary stop hinge 300 are not repeated.

[0033] like Fig.11 As shown, the telescopic placement rack 400 includes an outer tube 402, an upper inner tube assembly 401 is relatively telescopically arranged on the upper portion of the outer tube 402, and a lower inner tube assembly 403 is relatively telescopically arranged on the lower portion of the outer tube 402, so that the distance between the upper inner tube assembly 401 and the lower inner tube assembly 403 can be adjusted according to the height (size) of the poster, and the poster rack can be adapted to a wider range of poster sizes and has a stronger versatility. Further, as Fig.12 , 13 As shown in Figures 14, both ends of the outer tube 402 are symmetrically provided with upper slide grooves 4020 and lower slide grooves 4024 along the length direction. The upper inner tube assembly 401 and the lower inner tube assembly 403 adopt the same structure, and both include a support frame 4010 and an inner tube 4016. One end of the inner tube 4016 is fixedly installed with the support frame 4010, and the support frame 4010 is used to place posters. An "L"-shaped connecting plate 4013 is welded and fixed in the middle of the support frame 4010, and a first connecting screw 4014 and a second connecting screw 4015 are provided on the connecting plate 4013. The inner tube 4016 is provided with a first connecting screw hole 4018 and a second connecting screw hole 4019, so that the connecting plate 4013 (support frame 4010) and the inner tube 4016 are fixed by threaded connection. The other end of the inner tube 4016 relatively slides into the outer tube 402, and a hand screw hole 4017 is provided on the inner tube 4016. After the inner tube 4016 of the upper inner tube assembly 401 is inserted into the outer tube 402, the upper hand screw 405 penetrates the upper slide groove 4020 and is fixed to the hand screw hole 4017. By adjusting the tightness of the upper hand screw 405, the upper inner tube assembly 401 can be controlled to telescopically slide along the upper slide groove 4020. After the inner tube 4016 of the lower inner tube assembly 403 is inserted into the outer tube 402, the lower hand screw 404 penetrates the lower slide groove 4024 and is fixed to the hand screw hole 4017. After loosening the lower hand screw 404, the lower inner tube assembly 403 can be controlled to telescopically slide along the slide groove 4024. Thus, the distance between the upper inner tube assembly 401 and the lower inner tube assembly 403 can be adjusted.

[0034] Reference Figure 4 , 56. A cover plate 101 is installed on the top of the support column 100. A nut 102 is welded on the inner wall of the support column 100 below the cover plate 101. A lower fixing screw 201 is set at the lower end of the lifting gas support 200. The lower fixing screw 201 penetrates the cover plate 101 and is fixedly connected with the nut 102.

[0035] like Figure 6 , 7 As shown in FIGS. 8 and 9, the arbitrary stop hinge 300 includes a fixing plate 302 installed on the telescopic placement frame 400, a connecting seat 308 arranged on the fixing plate 302, and a connecting sleeve 301 hinged on the connecting seat 308, one end of the connecting sleeve 301 is fixed to the lifting gas support 200, and the other end of the connecting sleeve 301 is hinged to the connecting seat 308 through a rotating pin 303. An upper fixing screw 202 is arranged on the upper end of the lifting gas support 200, and the upper fixing screw 202 is threadedly connected and fixed to a connecting hole 304 provided on the connecting sleeve 301. A first fixing hole 305 and a third fixing hole 307 are provided on both sides of the fixing plate 302, and a second fixing hole 306 is provided on the connecting seat 308, and the second fixing hole 306 passes through the fixing plate 302. The outer tube 402 is provided with a first screw hole 4021, a second screw hole 4022 and a third screw hole 4023 at positions corresponding to the first fixing hole 305, the second fixing hole 306 and the third fixing hole 307. The first screw 309 passes through the first fixing hole 305 and the first screw hole 4021 and is fixed to the outer tube 402. The third screw 311 passes through the third fixing hole 307 and the third screw hole 4023 and is fixed to the outer tube 402. The second screw 310 passes through the second fixing hole 306 and the second screw hole 4022 and is fixed to the outer tube 402. Fig.10 As shown, when the telescopic placement rack 400 is assembled with any stop hinge 300 (lifting gas support 200), it can be rotated and stopped at any angle.

[0036] Furthermore, the downward force of the telescopic rack 400 on the arbitrary stop hinge 300 is balanced with the upward force of the lifting gas strut 200 on the arbitrary stop hinge 300, so that the telescopic rack 400 can stop at will during the lifting process.

[0037] The working process of the utility model is as follows: when adjusting the height of the telescopic placement rack 400, loosen the upper hand screw 405 and the lower hand screw 404 by hand, so that the upper inner tube assembly 401 and the lower inner tube assembly 403 can slide freely along the outer tube 402, and at the same time, the upper hand screw 405 slides along the upper slide groove 4020, and the lower hand screw 404 slides along the slide groove 4024. When the height is adjusted to match the size of the poster, tighten the upper hand screw 405 and the lower hand screw 404 to lock and fix the upper inner tube assembly 401 and the lower inner tube assembly 403. In addition, by rotating the outer tube 402, the inclination angle of the poster placement can be controlled by freely swinging the hinge 300 at any stop. By pulling the lifting gas strut 200, the height of the poster rack relative to the mounting base 103 can be adjusted up and down. Since the downward force (gravity) of the telescopic rack 400 on any stop hinge 300 is balanced by the upward force of the lifting gas strut 200 on any stop hinge 300, the telescopic rack 400 can be stopped at will during the lifting process.

[0038] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
