[0033] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0034] Reference example Figures 1 to 6, a ring network box that is easy to install, includes a box body 1, a mounting block 2, the mounting block 2 is provided with at least two liftable pressure plates 3, a first spring 4 is provided at the bottom of the mounting block 2, and an upward force is applied to the pressure plate 3, a retractable fixed block 5 is provided in the mounting block 2, a second spring 51 is provided in the fixed block 5, and abuts the mounting block 2, so that the fixed block 5 abuts the pressure plate 3, and fixing grooves 11 corresponding to the fixing blocks 5 are provided on both sides of the box body 1, and the mounting block 2 is provided with a reset assembly 6 for resetting the fixing block 5. When the box body 1 abuts the pressure plate 3 and applies downward pressure to the pressure plate 3, the fixing block 5 coincides with the fixing groove 11, and the fixed block 5 abuts the fixing groove 11, so that the mounting block 2 is connected and fixed to the box body 1;

[0035] It is worth mentioning that the pressure plate 3 is provided with a bearing portion 31 and is in a perpendicular relationship with the pressure plate 3. A countersunk hole 32 is provided on the back of the bearing portion 31. The first spring 4 abuts against the countersunk hole 32. The downward pressure of the box body 1 is applied to the pressure plate 3 through the bearing portion 31. The countersunk hole 32 increases the total height of the first spring 4, thereby improving the upper limit of energy storage.

[0036] It is worth mentioning that a mounting groove 21 is provided on one side of the mounting block 2, and a slide groove 22 for the lifting and lowering movement of the pressure plate 3 is provided on the side wall of the mounting groove 21, and a limit block 7 is provided on the top of the slide groove 22. A first groove 23 for accommodating the bearing portion 31 is provided at the bottom of the mounting groove 21, and the first blind hole 24 for accommodating the first spring 4 is provided in the first groove 23. Guide blocks 25 are provided on both sides of the mounting groove 21, and an inclined guide surface 251 is provided at the entrance of the guide block 25. The limit block 7 limits the rising distance of the pressure plate 3. The first groove 23 makes the bearing portion 31 flush with it. The first blind hole 24 increases the total height of the first spring 4 and increases the upper limit of energy storage. The box body 1 is guided into the mounting groove 21 through the guide surface 251, so that the fixing groove 11 and the slide hole 26 are on the same axis.

[0037] It is worth mentioning that the mounting block 2 is provided with a sliding hole 26 for the movement of the fixing block 5, a second groove 27 is provided between the two sliding holes 26, the second groove 27 is provided with a threaded hole 271, and a top plate 8 is provided at the entrance of the sliding hole 26. The second groove 27 cooperates with the linkage plate 62 to limit the range of movement of the fixing block 5, and the top plate 8 provides support for the second spring 51.

[0038] It is worth mentioning that the fixing block 5 is provided with a second blind hole 52 for accommodating the second spring 51. The second spring 51 abuts against the top plate 8. A connecting portion 53 is provided on one side of the fixing block 5. The second blind hole 52 increases the total height of the second spring 51. The connecting portion 53 cooperates with the linkage plate 62.

[0039] It is worth mentioning that the reset assembly 6 includes a screw 61 and a linkage plate 62. The linkage plate 62 is fixedly connected to the connecting portion 53. The screw 61 is threadedly connected to the threaded hole 271. The screw 61 passes through the linkage plate 62. The end of the screw 61 is provided with a stopper 63. The head of the screw 61 is provided with a detachable handwheel 64. When the screw 61 is used, the handwheel 64 is removed to prevent other users from rotating the screw 61. The linkage plate 62 causes the fixed block 5 to move synchronously, and the stopper 63 drives the linkage plate 62 to reset.

[0040] It is worth mentioning that mounting parts 28 are provided on both sides of the mounting block 2, and the mounting parts 28 are provided with several mounting holes 281. After measuring the length of the box 1, the mounting block 2 is placed in the designated area, and the fasteners are placed in the mounting holes 281 to fix the mounting block 2 to the ground.

[0041] The operating principle of the present invention is now described as follows:

[0042] The box body 1 is lifted to the top of the installation groove 21, and the box body 1 is made to enter the installation groove 21 through the guide surface 251. After the box body 1 abuts the bearing portion 31, as the box body 1 gradually sinks, it drives the pressure plate 3 to descend together, gradually opening the exit of the sliding hole 26, and the first spring 4 stores energy until the sliding hole 26 coincides with the fixing groove 11. The second spring 51 releases the elastic force to the fixing block 5, so that the fixing block 5 extends out of the sliding hole 26 and enters the fixing groove 11, so that the box body 1 is connected and fixed to the installation block 2.

[0043] Insert the handwheel 64 on the screw 61, rotate the handwheel 64 and drive the blocking part 63 to move in the direction of the linkage plate 62, and then push the linkage plate 62 to move in the opposite direction of the threaded hole 271, so that the fixing block 5 leaves the fixing groove 11 and retracts into the sliding hole 26. The second spring 51 is squeezed by the fixing block 5 and stores energy to prepare for the next time. The box body 1 is lifted out of the installation groove 21, and the first spring 4 releases the elastic force to the bearing part 31, so that the pressure plate 3 is quickly reset and blocks the exit of the sliding hole 26. Rotate the screw 61 to reset it until the fixing block 5 abuts against the pressure plate 3, then remove the handwheel 64 to complete the separation between the box body 1 and the installation block 2.

[0044] The above design scheme can enable the product to achieve the advantages of quick installation and easy operation.

[0045] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
