Detailed Description

Referring to fig. 1, fig. 2 and fig. 3, an advertising display screen convenient to remove and adjust, including base 1 and screen 12, be provided with the gyro wheel below base 1, the gyro wheel in this embodiment is universal wheel 2, be provided with support column 3 in the top of base 1, the vertical setting of support column 3, the lower extreme and the base 1 of support column 3 are connected fixedly, be provided with crane 4 in the top of support column 3, crane 4's bottom is cavity 5, the upper end of support column 3 stretches into in the cavity 5, so structure makes crane 4 up-and-down motion, screw hole 6 has been seted up on crane 4's lateral wall, be provided with screw-thread fit's locking bolt 7 with it in screw hole 6, locking bolt 7's tip and support column 3's outer wall butt, can realize locking and unblock to crane 4 through twisting locking bolt 7. After the lifting frame 4 is unlocked, the lifting frame can be moved up and down to adjust the height of the lifting frame.

The front of crane 4 is provided with loading board 11, screen 12 is fixed on loading board 11, middle part at crane 4 is fixed with the connecting plate 10 that stretches out forward, the middle part of the side of loading board 11 is rotated through the front end of pivot with connecting plate 10 and is connected, vertical spout 13 has been seted up on the lateral wall on the upper portion of crane 4, at the embedded slider 14 that is equipped with of spout 13, slider 14 and spout 13 interference fit, be provided with connecting rod 15 in the top of connecting plate 10, the both ends of connecting rod 15 are rotated through pivot and slider 14 respectively and with the upper portion of loading board 11 and are connected.

The slide block 14 is pushed up and down to change the position of the slide block in the sliding groove 13, the connecting rod 15 can be driven to move, the connecting rod 15 drives the bearing plate 11 to rotate around the front end of the connecting plate 10, so that the inclination angle of the bearing plate 11 can be changed, namely the inclination angle of the screen 12 is changed, the operation is very convenient, and after the slide block 14 is in addiction cooperation with the slide block 14 and slides to any position in the sliding groove 13, the slide block 14 is kept at the current position by the contact friction force between the slide block 14 and the sliding groove 13, so that the screen 12 is locked at the current angle.

Because the base 1 of the advertisement display screen is provided with the universal wheels 2, a user can easily push the display screen, and the position of the display screen is convenient to move; the height of the screen 12 can be adjusted by the user through adjusting the height of the lifting frame 4; in addition, the tilt angle of the screen 12 can be quickly adjusted by the up-and-down push-and-pull operation. This advertisement display screen, it is all very convenient to remove its position and adjust the height, the inclination of its screen 12, makes this advertisement display screen can be applicable to multiple service environment, satisfies different operation requirements.

In order to facilitate the pushing and pulling of the sliding block 14, a handle 16 is further arranged on the outer side of the sliding groove 13 in the embodiment, the handle 16 is fixedly connected with the sliding block 14, and the sliding block 14 can be conveniently pushed upwards and downwards after the handle 16 is held.

Considering that in the process of adjusting the inclination angle of the screen 12, when the screen 12 is adjusted to the limit angle, if the force is too strong, the upper edge of the loading plate 11 may contact and collide with the upper part of the lifting frame 4, or the upper edge of the loading plate 11 may contact and collide with the upper part of the lifting frame 4, and the screen 12 may be loosened after multiple collisions. To avoid this, an upper cushion 17 and a lower cushion 18 are provided at the upper and lower portions of the crane 4, respectively, the upper cushion 17 being located on the rotation path of the upper edge of the carrying plate 11, and the lower cushion 18 being located on the rotation path of the lower edge of the carrying plate 11. The upper cushion pad 17 and the lower cushion pad 18 can absorb the impact force between the bearing plate 11 and the lifting frame 4, thereby playing a role of buffering and effectively protecting the lifting frame 4 and the bearing plate 11.

The upper cushion pad 17 and the lower cushion pad 18 in this embodiment are both rubber pads, and are made of specifically foamed rubber, and the interior of the cushion pad is of a porous structure, so that the cushion pad has good elastic performance.

On this basis, still be fixed with spring 19 and lower spring 20 respectively at the top and the top in spout 13, when screen 12 is about to reach the extreme angle, slider 14 can contact with the spring earlier, the extrusion spring, the elasticity of spring acts on slider 14 for obtain the feedback force when user's push-and-pull slider 14, thereby can perception slider 14 is about to reach upper limit position or lower limit position, thereby can slow down the speed and the dynamics of push-and-pull slider 14 in advance, avoid loading board 11 and crane 4 collision, better play the guard action.

As shown in fig. 3, in the present embodiment, a hand wheel 9 is disposed at the holding end of the locking bolt 7, and the hand wheel 9 is coupled with the locking bolt 7 through a coupling 8. The specific connection mode is as follows: the hand wheel 9 is fixedly connected with a driving rotor 801 of the coupler 8, and the locking bolt 7 is fixedly connected with a driven rotor 802 of the coupler 8.

Because a certain relative rotation resistance exists between the driving rotor 801 and the driven rotor 802 of the coupler 8, when the screwing resistance of the locking bolt 7 is smaller than the rotation resistance, a user can rotate the hand wheel 9 to drive the locking bolt 7 to synchronously rotate; when the screwing resistance of the locking bolt 7 is greater than the rotation resistance (that is, the locking bolt 7 already abuts against the support column 3), the driving rotor 801 and the driven rotor 802 rotate relatively, and at this time, even if a user rotates the hand wheel 9 with a larger force, the locking bolt 7 cannot rotate continuously, so that the locking bolt 7 is prevented from being screwed too tightly, and the follow-up convenient operation is ensured. The locking bolt 7 can be loosened by rapidly and reversely rotating the hand wheel 9, and finally the lifting frame 4 is unlocked.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
