Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0026] An embodiment of the present utility model discloses a road construction protective plate.

[0027] The present utility model provides a road construction protective plate as shown in Figures 1-5 Figure 31, which includes a protective plate body 1. A cross slider 2 is integrally formed on one side of the protective plate body 1. A limit sliding groove 3 is provided on the other side of the protective plate body 1, and the limit sliding groove 3 is adapted to the cross slider 2. A locking assembly is provided on the protective plate body 1, and the locking assembly is used to fix two spliced protective plate bodies 1.

[0028] The locking assembly includes a lock hole 4 opened on the wall of the cross slider 2, an activity cavity 5 opened in the protective plate body 1, a lock rod 6 slidably connected in the activity cavity 5, an inclined section opened at one end of the lock rod 6 close to the limit sliding groove 3, a rectangular groove 7 opened on the outer wall of the lock rod 6, a rotating rod 8 located at the top of the lock rod 6, and one end of the rotating rod 8 is rotatably connected to the inner wall of the protective plate body 1 through a bearing, and a poking rod 9 fixedly sleeved on the outer wall of the rotating rod 8, and the bottom end of the poking rod 9 is located in the rectangular groove 7.

[0029] When the cross slider 2 of the protective plate body 1 is inserted into the limiting slide groove 3 of another protective plate body 1, the two adjacent protective plate bodies 1 are spliced ​​left and right, and the locking rod 6 of the protective plate body 1 is inserted into the locking hole 4 of the other protective plate body 1, so that the two protective plate bodies 1 are locked as a whole, and a single protective plate body 1 cannot move or rotate horizontally. When unlocking is required, the rotating rod 8 is turned clockwise to make the toggle rod 9 rotate in the rectangular groove 7, pushing the locking rod 6 out of the locking hole 4, and the protective plate body 1 can be taken out upwards and disassembled between the two protective plate bodies 1. The operation is simple and convenient, and no other tools are required.

[0030] like Figure 2 As shown, the end of the locking rod 6 extends into the limiting slide groove 3, and the outer diameter of the locking rod 6 is the same as the inner diameter of the locking hole 4. A reset member 10 is connected between the end of the locking rod 6 away from the limiting slide groove 3 and the inner wall of the protective plate body 1. The reset member 10 is not specifically limited. To conform to the actual situation, the reset member 10 can be a spring.

[0031] The other end of the rotating rod 8 extends out of the outer side of the protective plate body 1 , and a knob 11 is fixedly mounted on the end of the rotating rod 8 .

[0032] By turning the rotating rod 8 through the knob 11, the toggle rod 9 pushes the locking rod 6 away from the locking hole 4. During this process, the locking rod 6 continuously presses the reset member 10 inward. After the disassembly is completed, the locking rod 6 automatically resets, so that the locking rod 6 can be automatically inserted into the locking hole 4 when the two protective plate bodies 1 are subsequently spliced.

[0033] In order to improve the stability of the device, Figures 4-5 As shown, a support block 12 is provided on the back of the protective plate body 1, and the support block 12 can be fixed on the ground by rivets to resist bad weather. A rotating cylinder 13 is rotatably connected to the inner cavity of the support block 12, and a threaded rod 14 is threadedly connected to the inner side of the rotating cylinder 13. A ring 15 is rotatably connected to the bottom end of the threaded rod 14, and the ring 15 is fixedly connected to the protective plate body 1 by a connecting plate 16.

[0034] A stable triangular structure is formed between the protective plate body 1, the connecting plate 16 and the support block 12 to prevent the protective plate body 1 from tipping over due to external impact; under the connecting action of the ring 15, the threaded rod 14 drives the connecting plate 16 to move vertically upward by rotating the rotating cylinder 13, so that the connecting plate 16 drives the protective plate body 1 to move upward as a whole, so as to disassemble the two adjacent protective plate bodies 1.

[0035] Finally, to improve the functionality of the device, e.g. Figure 4As shown, a first bevel gear 17 is fixedly installed at the bottom of the rotating cylinder 13, and a through hole for the threaded rod 14 to move is provided on the wall of the first bevel gear 17. A second bevel gear 18 is meshed with the back of the first bevel gear 17, and a movable rod 19 is fixedly installed on the back of the second bevel gear 18.

[0036] The movable rod 19 is rotatably connected to the support block 12. One end of the movable rod 19 extends out of the outside of the support block 12, and a turning handle 20 is fixedly installed at this end of the movable rod 19. The turning handle 20 can be connected to the movable rod 19 by the input shaft of a driving motor, and unlocking is carried out by starting the driving motor, further saving manpower.

[0037] By turning the turning handle 20 on the back of the support block 12, the movable rod 19 drives the second bevel gear 18 to rotate, and the first bevel gear 17 meshed with the second bevel gear 18 rotates, so that the first bevel gear 17 drives the rotating cylinder 13 to rotate horizontally along its axis.

[0038] Only some exemplary embodiments of the present invention are described in the above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
