Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a movable bookshelf includes: the bookshelf comprises a bookshelf body 1 and a bookshelf body 1, wherein the bookshelf body 1 is used for placing books;

the trundle mechanism 3 is arranged below the bookshelf body 1, and the trundle mechanism 3 is used for moving the bookshelf body 1;

the support mechanism 4 is installed below the bookshelf body 1, and the support mechanism 4 is used for supporting the bookshelf body 1;

wherein, the lower part of the bookshelf body 1 is provided with an accommodating space 2 for accommodating a caster wheel mechanism 3 and a supporting mechanism 4; the caster wheel mechanism 3 is rotatably connected with the bookshelf body 1 and the supporting mechanism 4, when the caster wheel mechanism 3 is used, the caster wheel mechanism 3 is attached to the ground, and when the caster wheel mechanism 3 is not used, the caster wheel mechanism 3 upwards rotates for 180 degrees;

the bookshelf body 1 is also provided with a positioning mechanism which is used for positioning the foot wheel mechanism 3.

The working principle is as follows: as shown in fig. 1 and 2, when the bookshelf body 1 needs to be moved, the caster mechanisms 3 face downward, so that the casters 304 are attached to the ground, the caster mechanisms 3 are fixed by the positioning mechanisms, the casters 304 are prevented from rotating normally due to the rotation of the caster mechanisms 3, and the movement can be realized by pushing the bookshelf body 1; when not needing to remove, supporting mechanism 4 is used for supporting bookshelf body 1, and truckle mechanism 3 is 180 degrees down rotatory, fixes truckle mechanism 3 through positioning mechanism, prevents that truckle mechanism 3 from falling back, comes to laminate with ground through supporting mechanism 4, realizes the support to bookshelf body 1.

The support mechanism 4 includes: supporting shoe 401, supporting shoe 401 and bookshelf body 1 fixed connection, are equipped with support column space 404 in the supporting shoe 401, and support column space 404 is used for holding support column 402, and fixed mounting has adjusting screw 403 on the support column 402, adjusting screw 403 and supporting shoe 401 threaded connection.

The working principle is as follows: as shown in fig. 1 and 2, the adjusting screw 403 is in threaded connection with the supporting block 401, the height of the supporting column 402 can be changed by rotating the adjusting screw 403, the adjusting screw 403 is rotated clockwise, the supporting column 402 moves downward, the supporting column 402 continues to move downward along with the continued rotation of the adjusting screw 403, the bookshelf body 1 is supported by the adjusting screw 403, and the space at the bottom of the bookshelf body 1 can be increased, when the space is larger than the caster mechanism 3, the caster mechanism 3 can rotate freely, when the caster mechanism 3 needs to be rotated (when the bookshelf body 1 needs to be pushed, the caster mechanism 3 needs to be rotated to enable the caster 304 to be in contact with the ground, when the bookshelf does not need to be pushed, the caster mechanism 3 needs to be rotated 108 ° to reduce the space between the bookshelf body 1 and the ground), and the operation is completed as above; when fixing bookshelf body 1 and putting in a certain position, in order to reduce the distance of bookshelf body 1 and ground, anticlockwise rotation adjusting screw 403 makes support column 402 upward movement, will make bookshelf body 1 and the distance on ground diminish like this to reach the user's demand, prevent that external article from getting into in the space of bookshelf body 1 and ground, solve the puzzlement that is used for.

The number of the support columns 402 is four, and the support columns are distributed along the periphery of the bottom of the bookshelf body 1.

The working principle is as follows: the four-point support can enable the bookshelf body 1 to be stably placed, the phenomenon of inclination is avoided, and the use safety of a user is guaranteed.

The caster mechanism 3 includes: truckle installation piece 301, fixed mounting has truckle 304 on the truckle installation piece 301, and the both ends of truckle installation piece 301 are equipped with pivot 303, and pivot 303 rotates with bookshelf body 1 and supporting shoe 401 to be connected, and one side that is close to bookshelf body 1 on truckle installation piece 301 is equipped with locating hole 302, and the quantity of locating hole 302 is two, and the diameter equals, about two locating hole 302 are perpendicular, and with pivot 303 symmetric distribution.

The working principle is as follows: the caster mounting block 301 can drive the caster 304 to rotate around the rotating shaft 303, when the caster 304 is needed, the caster mounting block 301 is rotated to enable the caster to be attached to the ground, the caster 304 is ensured to be attached to the ground all the time through the matching of the positioning mechanism and the positioning hole 302, and the caster 304 is prevented from rotating around the rotating shaft 303 to cause the caster 304 to rotate abnormally; when the truckle 304 is not needed, the truckle installation piece 301 is rotated, make the truckle 304 up, cooperation through positioning mechanism and locating hole 302, prevent that truckle 304 from falling back, truckle 304 up, just can realize the purpose of removing the space of truckle 304, through support column 402 and ground laminating, and support bookshelf body 1, just so can reduce the space of bookshelf body 1 and ground, prevent that external article from getting into in the space of bookshelf body 1 and ground, the whole height of bookshelf body 1 has also been reduced, the puzzlement that is used for is solved.

The positioning mechanism includes: the bookshelf comprises a positioning pin 106, wherein a spring stop 104 is installed on the positioning pin 106 in a threaded mode, the spring stop 104 is in sliding fit with a spring hole 101 in the bookshelf body 1, a compression spring 103 is sleeved on the positioning pin 106, two ends of the compression spring 103 are attached to the bookshelf body 1 and the spring stop 104 respectively, a handle 102 is arranged at one end of the positioning pin 106, the handle 102 is arranged on the outer side of the bookshelf body 1, the other end of the positioning pin 106 is matched with a positioning hole 302, and a shaft stop 105 is installed on the outer side of the spring hole 101.

The working principle is as follows: two ends of the compression spring 103 are respectively attached to the bookshelf body 1 and the spring retainer 104, the spring retainer 104 is installed on the positioning pin 106 in a threaded mode, the position of the spring retainer 104 on the positioning pin 106 is adjusted through threads, the use requirement of the compression spring 103 can be met, the problem that the length of the compression spring 103 is inconsistent due to cutting can be solved, the spring force of each compression spring 103 can be guaranteed, namely the position of the positioning pin 106 in the positioning hole 302 is guaranteed, and the change cannot occur; when the caster mounting block 301 is rotated to a fixed position (two positions, one position is upward and the other position is downward), the handle 102 is loosened, the compressed compression spring 103 releases the elastic force to push the spring stopper 104 to move, so that the positioning pin 106 is driven to move, the positioning pin 106 is inserted into the positioning hole 302 to complete the fixation of the caster mounting block 301, and the caster mounting block 301 cannot rotate around the rotating shaft 303; the shaft stopper 105 is installed on the outer side of the spring hole 101, and the spring stopper 104 and the spring hole 101 can be prevented by arranging the shaft stopper 105, so that the spring stopper 104 can normally move in the spring hole 101.
