Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

the utility model discloses a screen convenient to remove, as shown in fig. 1 and 2, mainly include screen body 1, install at the base 2 of screen body 1 bottom and rotate the travelling wheel 3 of connecting in base 2 lower surface four corners department, in this embodiment, base 2 lower surface middle part has still been seted up and has been receive and release groove 5, it is provided with one along vertical direction to slide on receiving and releasing groove 5 cell wall and receive and release a piece 6 to receive and release 6 tops of piece and receive and release five pullback springs 7 of fixedly connected with between the 5 roof in groove, still be provided with on the base 2 and receive and release 8. In the daily use of the screen, the folding and unfolding component 8 can cause the folding and unfolding supporting block 6 to extend out of the folding and unfolding groove 5 and abut against the ground, and the pull-back spring 7 is stretched at the moment, so that the screen can be stably placed because the folding and unfolding supporting block 6 is in contact with the ground; when the screen needs to be moved, as long as the contact retraction part 8 acts on the retraction support block 6, the pull-back spring 7 can be restored to the natural state, so that the lower surface of the retraction support block 6 can move to the upper part of the bottom end of the travelling wheel 3, the four travelling wheels 3 on the base 2 land, and the screen can be pushed to move freely.

As shown in fig. 3, a push groove 811 extending to the retraction groove 5 along the horizontal direction is provided on the vertical outer side wall of the base 2, the retraction part 8 in this embodiment includes a push plate 81 and a push angle 82, the push plate 81 slides along the horizontal direction and is disposed on the groove wall of the push groove 811, the push angle 82 is disposed at one end of the lower surface of the push plate 81 close to the retraction groove 5, and a transition arc angle 61 is disposed at the edge of the top end of the retraction support block 6 close to the push groove 811. When the screen is moved, the push plate 81 is positioned in the push groove 811 (see fig. 5), and the retraction spring drives the retraction support block 6 to be above the travelling wheel 3; when the screen needs to be placed, the push plate 81 is pushed into the folding and unfolding groove 5, so that the push angle 82 is in sliding and abutting joint with the transition arc angle 61, at the moment, the push plate 81 can overcome the elasticity of the pull-back spring 7, the folding and unfolding support block 6 is pushed downwards, and the folding and unfolding support block 6 abuts against the ground.

As shown in fig. 3 and 4, one end of the push plate 81 far from the storage groove 5 is rotatably provided with a pull plate 83, the pull plate 83 and the push plate 81 rotate by 90 degrees, one end of the pull plate 83 far from the push plate 81 is also rotatably provided with a hand ring 84, the rotation axis of the hand ring 84 is in the same direction as the length direction of the pull plate 83, and meanwhile, the hand ring 84 is also provided with a limiting member 85 for fixing the position of the pull plate 83 along the length direction of the push groove 811. When the screen is moved, the push angle 82 is far away from the folding and unfolding support block 6, the push plate 81 is positioned in the push groove 811, the pull plate 83 extends back out of the push groove 811 at the moment, and the pull plate 83 is magnetically connected with the side wall of the base 2 after rotating 90 degrees, so that the screen can be stably moved. When the screen is normally used, the push plate 81 extends out of a part of the folding and unfolding groove 5, the pull block can slide into the push groove 811, and the limiting piece 85 can limit the movement of the pull block, so that the push plate 81 can be stably abutted against the folding and unfolding support block 6, and the placing stability of the screen is improved.

As shown in fig. 4 and 5, the limiting member 85 mainly includes a rectangular limiting fixture block 851, the limiting fixture block 851 is integrally connected to the circumferential wall of the bracelet 84, one end of the push groove 811 far away from the retraction groove 5 is relatively provided with a rectangular limiting entering groove 852, the limiting entering groove 852 and the limiting fixture block 851 are arranged in a one-to-one correspondence manner, one end of the limiting entering groove 852, which is close to the retraction groove 5, is further provided with a limiting clamping groove 853, and the limiting clamping groove 853 is an arc groove. When the push plate 81 is moved, the limit fixture block 851 is opposite to the limit groove 852, and the push plate 81 can normally move; after pushing plate 81 and receiving and releasing supporting block 6 butt, spacing fixture block 851 at this moment enters spacing draw-in groove 853 through spacing entering groove 852, then rotates bracelet 84, and during spacing fixture block 851 can change over to spacing draw-in groove 853 this moment, spacing fixture block 851 and spacing draw-in groove 853 keep away from the cell wall butt of receiving and releasing groove 5, can fix a position pushing plate 81.

As shown in fig. 5, in order to improve the movement stability of the screen, two ends of the length direction of the lower surface of the base 2 are integrally connected with the support plates 4, the two support plates 4 penetrate through the yielding chute 41 along the horizontal direction, the yielding chute 41 extends along the vertical direction, a linkage block 42 is slidably arranged in the yielding chute 41 along the vertical direction, and a linkage rod 43 is fixedly connected between the linkage block 42 and the retractable support block 6; when the screen is required to be moved, if the pullback spring 7 is aged, the retractable support block 6 cannot completely leave the ground, at the moment, the retractable support block 6 can be manually lifted, the linkage block 42 moves upwards, the abdicating chute 41 is positioned below the linkage block 42 to form a support groove 44, then a support block 45 is inserted into the support groove 44, and the retractable support block 6 can leave the ground by utilizing the supporting force of the support block 45; in the daily use of the screen, the linkage block 42 is positioned at the bottom end of the abdicating chute 41, and the support block 45 can be placed above the linkage block 42 (see fig. 3) for use.

As shown in fig. 5, a plurality of connecting screw grooves 621 are concavely arranged on the lower surface of the retractable support block 6, a connecting screw block 622 is connected to the connecting screw grooves 621 through screw threads, and a clamping cone 62 is integrally connected to the bottom end of the connecting screw block 622. The lower surface of the retractable support block 6 is provided with a plurality of clamping cones 62, and the tips of the clamping cones 62 are arranged downwards; when the screen is moved, the pull-back spring 7 is in a natural state, and the bottom end of the clamping cone 62 is positioned above the bottom end of the travelling wheel 3. When the retractable support block 6 is supported on the ground, the clamping cone 62 sinks into the ground, so that the mounting stability of the screen can be further improved.

The working process is as follows:

in the daily use of the screen, the push plate 81 extends into the retraction groove 5, the push plate 81 is abutted against the upper surface of the retraction support block 6, the retraction support block 6 is made to extend out of the retraction groove 5 and abut against the ground, and the retraction support block 6 is in contact with the ground surface, so that the screen can be stably placed; when the screen needs to be moved, the push plate 81 is pulled into the push groove 811, so that the push plate 81 is far away from the retractable support block 6, and at the moment, the pull-back spring 7 can be restored to a natural state, so that the lower surface of the retractable support block 6 can be moved to the upper part of the bottom end of the travelling wheel 3, and the four travelling wheels 3 on the base 2 are grounded, so that the screen can be pushed to move freely.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
