• the first protruding edges move relative to the second protruding edges in the circumferential direction enables the first protruding edges to be aligned with the second protruding edges, and the first protruding edges and the second protruding edges are buckled together in a direction opposite to an axial opposite movement to achieve buckling together.
• the buckling hooks have elasticity for contracting in a horizontal direction; and the protruding cavity structure defines a pushing portion located on an upper side of the protruding edge, and the pushing portion moves in the axial direction to push the buckling hooks to contract inward in the horizontal direction, causing the buckling hooks and the protruding edge to be separated from each other release from the buckling together.
• two of the buckling hooks are provided, opposite sides of the two of the buckling hooks respectively comprise a pulling rib and a guiding groove, an end of the pulling rib is used as a fixed end with one of the buckling hooks, another end is disposed in the guiding groove used as a movable end, and the movable end moves in the guiding groove due to a compressing force for compressing the spring module.
• the technical solution has the following advantages, the first locking structure is disposed on a lower end of the upper cover of the spring module, the second locking structure is disposed on the upper end surface of the base, the spring module is compressed to enable the first locking structure and the second locking structure to be buckled together to lock the spring module in the compressed state, the disassembled spring modules can be maintained in the compressed state, occupied spaced for relocation and transportation are saved, and labor costs are saved.
• a lower end surface of the upper cover 2 comprises a first locking structure 21, an upper end surface of the base 1 comprises a second locking structure 11, the first locking structure 21 and the second locking structure 11 face each other and are disposed in a chamber of the spring module, and the spring module is compressed to enable the first locking structure 21 and the second locking structure 11 to be buckled together in a vertical direction to lock the spring module in a compressed state; and the spring module rotates to release the first locking structure 21 from buckling to the second locking structure 11 so as to release the spring module.
• the upper end surface of the base 1 forms a protruding cavity structure 111, which has a cylindrical shape, along a compression direction of the spring module, an outer edge of a top of the protruding cavity structure 111 comprises protruding edges 112, which are discontinuous, as the second locking structure 11, and gaps 113 are defined between adjacent protruding edges 112;
• the lower end surface of the upper cover 2 comprises buckling hooks corresponding to the protruding edges 112 one to one and at intervals and used as the first locking structure 21;
• the spring modules being maintained in the compressed state occupy less space, and more of the spring modules can be transported at one time, which is also convenient to relocate for the users and saves labor costs at this time.
• the spring module When the spring module needs to be released for splicing, the spring module rotates to drive the buckling hooks to be separated from the positioning surfaces 1121 of the protruding edges 112 to reach the gaps 113, at this time, the spring module in the compressed state drives the spring module to be in a released state by a restoring force, and the spring modules can be then assembled into the elastic module for use by the user through the connecting members 5.
• the aforementioned rotation of the spring module means that the upper cover 2 and the base 1 rotate in opposite directions, thereby resulting in a relative movement.
• a closing plug 12 is disposed in a middle portion of the protruding cavity structure 111 of the base 1, when the closing plug 12 is installed in the base 1, the closing plug 12 can push the protruding edge 112 to extend outward along a radial direction, and after taking out the closing plug 12, the protruding edge 112 will contract in a direction towards a center of a circle, thereby causing the protruding edge 112 to be separated from the hook portions 212.
• relative movement of the protruding edge 112 and the hook portions 212 in the circumferential direction in Embodiment 1 is changed to a relative movement in the radial direction. Eventually, the protruding edge 112 can be separated from the hook portions 212, thereby releasing the spring module.
• Embodiment 1 As long as the base 1 and the upper cover 2 rotate relative to each other, the protruding edges 112 and the hook portions 212 will rotate relative to each other along a circumferential direction, causing the protruding edges 112 to be separated from the hook portions 212 for unlocking. Therefore, a locking structure of Embodiment 1 is not sufficiently stable, and operational mistakes are prone to happen, resulting in the spring module being unlocked. In the solution of Embodiment 2, as long as the closing plug 12 is taken out, the spring module will instantly release an elastic force, which is also prone to accidents.
