Example 1: comprises a rocker arm component 1 and a round base 2; universal wheel 4 is installed to the bottom of rocking arm subassembly 1, rocking arm subassembly 1 divide into first rocking arm 11 and second rocking arm 12, and first rocking arm 11 comprises rocking arm left 112 and 111, and second rocking arm 12 comprises rocking arm right 122 and front end magnet right 121, and rocking arm left 112 and 111, the position department that rocking arm right 122 and front end magnet right 121 are connected all is provided with the articulated elements, and rocking arm subassembly 1 slidable mounting is in the inside of base, and the upper end of base is provided with handle 3.

It should be noted that, the movable base is provided with a main handle 3, four rocker arm assemblies 1, a circular base 2 and universal wheels 4, the universal wheels 4 installed at the lower ends of the rocker arm assemblies 1 start to rotate through the handheld handle 3, the movable base starts to roll, and the effect of moving the base is achieved, in addition, the movable base is composed of the four rocker arm assemblies 1, the hollow steel frame structure of the movable base saves materials and reduces the dead weight, in addition, the rocker arm assemblies 1 comprise a right first rocker arm 11 and a second rocker arm 12, the first rocker arm is composed of a left rocker arm 112 and a left rocker arm 111, the second rocker arm 12 is composed of a right rocker arm 122 and a right front end magnet 121, meanwhile, the left rocker arm 112 and the left front end magnet 121 are hinged through hinge parts, the hinge parts are two-folding hinge parts, the hinge parts can enable the right rocker arm 111 and the right front end magnet 121 to be inwardly turned by 90 degrees through the two-folding hinge parts, the front ends of the right rocker arm 122 and the front end magnet 121 are made to abut against, the unfolding state of the movable base is achieved, the carrying area of the movable base is increased, and more goods are transshipped.

Example 2: a sliding cavity 21 is formed in the circular base 2, the cross sections of the sliding cavity 21 and the circular base 2 are in a circular ring-shaped track, and the rocker arm assembly 1 is assembled in the sliding cavity 21 track in a sliding mode.

It should be noted that, a sliding cavity 21 is arranged in the circular base 2, a track surface of the sliding cavity 21 is in a circular shape, meanwhile, the rocker arm assemblies 1 are assembled in the sliding cavity 21 in a sliding mode, the first rocker arm 11 and the second rocker arm 12 are unfolded, and then 111 and the front end magnet are turned over for 90 degrees to the right, so that the unfolding state of the movable base is achieved, or the four rocker arm assemblies 1 are moved, so that the rocker arm assemblies 1 are attached to each other, the contraction state of the movable base is achieved, and the effect of convenient storage is achieved.

Example 3: the shapes of the first rocker arm 11 and the second rocker arm 12 are both in sector arrangement of 15 degrees, and when the first rocker arm 11 and the second rocker arm 12 slide in the track of the sliding cavity 21, the first rocker arm 11 and the second rocker arm 12 are tightly attached to each other.

It should be noted that, because the first rocker arm 11 and the second rocker arm 12 have the same shape and the cross sections thereof are all in a sector arrangement of "15 °, when the first rocker arm 11 and the second rocker arm 12 slide in the slide cavity 21, the four sets of rocker arm assemblies 1 thereof can be attached to each other, thereby achieving the maximum convenience of storage.

Example 4: the first square groove 114 that the oral area was up has been seted up to the position department that the up end of rocking arm left 112 is close to 111, installs the bayonet 113 in the first square groove 114, and the position department that the up end of rocking arm right 122 is close to front end magnet right side 121 has seted up oral area second square groove 124 up, installs buckle 123 in the second square groove 124, through hasp and the mutual block of

bayonet

113, 111 and the equal 90 inside upsets of front end magnet right side 121.

It should be noted that, when the movable base is in the unfolded state, 111 and the front end magnet right 121 are both turned inward by 90 °,111 abuts against the head of the front end magnet, but in the actual moving process of the movable base, the rocker arm assembly 1 may be contracted and closed due to bumpy road conditions between the magnets, so that a first square groove 114 with an upward opening is formed at a position close to 111 on the upper end surface of the rocker arm left 112, a clamping bolt 113 is installed in the first square groove 114, a second square groove 124 with an upward opening is formed at a position close to the front end magnet right 121 on the upper end surface of the rocker arm right 122, and a clamping buckle 123 is installed in the second square groove 124; the stability of the deployed state of the movable base is further improved by the engagement between the buckle 123 and the latch 113.

Example 5: rectangular long grooves with outward openings are formed in the left 112 side surface and the right 122 side surface of the rocker arm, and supporting rods 6 are arranged in the rectangular long grooves.

Example 6: the connection positions of the two ends of the support rod 6 and the inner wall of the rectangular long groove are respectively supported through deep groove ball bearings, and a plurality of rings of elastic ropes are respectively wound at the positions, located at the supporting bottom ends of the deep groove ball bearings, of the two ends of the support rod 6.

It should be noted that, the connecting positions of the two ends of the support rod 6 and the inner wall of the rectangular long groove are respectively supported by the deep groove ball bearings, so that the support rod 6 can rotate under the action of the deep groove ball bearings, and a plurality of rings of elastic ropes are respectively wound at the positions of the two ends of the support rod 6 at the supporting bottom end of the deep groove ball bearings, so as to enable the support rod 6 to generate radial tension after rotating.

Example 7: the side of the support rod 6 is provided with a screen 5 in a surrounding way, and two ends of the screen 5 are respectively and fixedly arranged inside the left rocker arm 112 and the right rocker arm 122.

It should be noted that, when the movable base is in an expanded state, the first rocker 11 and the second rocker are separated from each other, the screen 5 is installed around the side surface of the support rod 6, and the screen 5 causes the support rod 6 to generate radial tension after rotating, one is that the screen 5 is installed around the side surface of the support rod 6, when the movable base is loaded with goods, the surface area for bearing the goods is increased, and meanwhile, the goods are prevented from falling off in the moving process, the other is that in order that the front end magnet I and the front end magnet II are abutted, the support rod 6 generates radial tension after rotating to enable the front end magnet I and the front end magnet II to be attached more tightly, and the third is that when the movable base is in a contracted state, the support rod 6 can automatically rotate back due to being provided with a plurality of elastic ropes, and the screen 5 is retracted into the rocker assembly 1, so that the accident that the goods fall off outside and wear is prevented.
