[0033] As shown in the attached Figures 1-11 A steel grating plate that is convenient for splicing and assembling, including a steel grating plate 1, at least one first connection device and a second connection device are provided on the steel grating plate 1. The first connection device includes a plug-in groove 12 and a locking assembly 2 fixedly connected to the steel grating plate 1. The plug-in groove 12 is opened on an outer side wall of the steel grating plate 1.

[0034] The steel grating plate 1 is provided with a second connection device on the other outer side wall opposite to the plug-in groove 12. The second connection device includes a plug-in block 3 that is buckled with the plug-in groove 12. The plug-in block 3 is provided with a locking hole 31 penetrating through it. One end of the plug-in block 3 is provided with an inclined surface. Through the snap-fit design of the plug-in groove 12 and the plug-in block 3, the steel grating plate 1 can be quickly and conveniently assembled and disassembled, reducing the installation time and labor costs. The design of the locking assembly 2 and the locking hole 31 ensures that the assembled steel grating plate 1 is firmly connected and not easily loosened, improving the safety and durability of the structure. This connection method fixes the locking assembly 2 inside the steel grating plate 1, thereby facilitating transportation and storage.

[0035] In some embodiments, the locking assembly 2 includes a housing 24. A sliding block 25 is slidably arranged in the housing 24. The sliding block 25 is provided with a first unlocking groove 21, a locking groove 29, and a guiding track 23. A spring 26 is arranged between the sliding block 25 and the housing 24. An elastic rod 27 is swingably arranged on the housing 24. The elastic rod 27 is slidably connected to the guiding track 23.

[0036] In some embodiments, the slide block 25 is provided with a second unlocking groove 22, and the depth of the second unlocking groove 22 is the same as that of the first unlocking groove 21. The guide track 23 includes a forward groove 231 and a retracting groove 232 that are connected to each other, a slope 2311 is provided in the forward groove 231, and a first step 2321, a second step 2322 and a third step 2323 are provided in the retracting groove 232, and the depths of the first step 2321, the second step 2322 and the third step 2323 increase in sequence.

[0037] In some embodiments, an abutment portion 271 is disposed at one end of the elastic rod 27 , and a lower end surface of the abutment portion 271 is always in abutment with an inner bottom wall of the guide track 23 .

[0038] Through the cooperation of the abutting portion 271 and the first step 2321, the second step 2322 and the third step 2323, the guide rail 23 ensures the moving path of the abutting portion 271; that is, it moves from the locking groove 29 along the forward groove 231 to the second locking chute 22, and then moves from the second locking chute 22 to the first locking chute 21 under the guidance of the first step 2321 and the guide rail 23, and then moves from the first locking chute 21 along the retreat groove 232 back to the locking groove 29 under the guidance of the second step 2322 and the guide rail 23. The third step 2323 is provided to ensure that the abutting portion 271 does not enter the retreat groove 232 but enters the forward groove 231 when moving upward. A slope 2311 is provided in the forward groove 231 to lift the abutting portion 271 to offset the drop caused by the first step 2321, the second step 2322 and the third step 2323, thereby ensuring that the locking assembly 2 can continuously cycle.

[0039] In some embodiments, the slide block 25 is provided with a positioning rod 28 adapted to the size of the locking hole 31, and one end of the positioning rod 28 is provided with an inclined guide portion 281. Through the inclined guide portion 281, the positioning rod 28 can be subjected to a downward extrusion force when the plug-in block 3 is inserted or pulled out, thereby moving downward.

[0040] In some embodiments, the slide block 25 is further connected to an unlocking protrusion 251 , and the axis of the unlocking protrusion 251 is perpendicular to the axis of the positioning rod 28 .

[0041] During use, the operator can move the unlocking protrusion 251 to make the elastic rod 27 located in the second unlocking groove 22. At this time, the positioning rod 28 moves out of the range of the locking hole 31, and the plug-in block 3 can move freely. The operator can release the unlocking protrusion 251 and then pull out the steel grid plate 1 with both hands. During the pulling-out process, the plug-in block 3 will squeeze the inclined guiding portion 281 of the positioning rod 28, making the elastic rod 27 located in the first unlocking groove 21. When the steel grid plate 1 needs to be installed again, there is no need to adjust the locking assembly 2. The operator can insert the plug-in block 3 on the steel grid plate 1 into the plug-in groove 12 of another steel grid plate 1 with both hands to complete the splicing and installation of the steel grid plate 1. The two-handed operation ensures the convenience and safety of the operator during the installation and disassembly process.

[0042] Furthermore, multiple locking assemblies 2 on the same side wall of the steel grid plate 1 can be installed at positions with different unlocking directions, thereby reducing the probability of accidental unlocking.

[0043] In some embodiments, a connecting sleeve 4 is sleeved on the unlocking protrusion 251, and the connecting sleeve 4 connects multiple unlocking protrusions 251 to each other. Thus, by moving the connecting sleeve 4, multiple unlocking protrusions 251 can be moved at one time.

[0044] In some embodiments, a positioning hole 11 is provided on the upper end surface of the steel grid plate 1. The steel grid plate 1 is detachably provided with a rubber anti-slip pad 13 through the positioning hole 11. The lower end of the rubber anti-slip pad 13 is connected with a positioning post adapted to the positioning hole 11. The rubber anti-slip pad 13 is also provided with a receiving groove 131 adapted to the connecting sleeve 4. The upper end surface of the rubber anti-slip pad 13 is flush with the unlocking protrusion 251. The rubber anti-slip pad 13 provides an additional anti-slip effect and increases the safety of the steel grid plate 1, especially when used in a wet or smooth environment. Since the rubber anti-slip pad 13 is fixed by the positioning post, it can be easily disassembled and replaced, which makes maintenance and cleaning more convenient. Furthermore, the rubber anti-slip pad 13 is also provided with a receiving groove 131 adapted to the connecting sleeve 4. In actual use, the steel grid plate 1 is provided with two groups of first connecting devices perpendicular to each other, which can strengthen the installation firmness of the rubber anti-slip pad 13, and the upper end surface of the rubber anti-slip pad 13 is flush with the connecting sleeve 4 to prevent accidental contact with the connecting sleeve 4 during daily use, resulting in unlocking.

[0045] The working principle of the present utility model is as follows:

[0046] Insert the insertion block 3 of the steel grating plate 1 into the insertion slot 12 of another steel grating plate 1. During this process, the elastic rod 27 in the locking assembly 2 is originally in the first unlocking groove 21. Under the action of the inclined surface of the insertion block 3, the positioning rod 28 is squeezed, and the elastic rod 27 leaves the first unlocking groove 21, and then falls into the locking groove 29 under the action of the spring 26. Thus, the sliding groove block 25 drives the positioning rod 28 to extend out and penetrate the locking hole 31, thereby completing the locking of the insertion block 3, and further completing the mutual splicing and fixing between the two steel grating plates 1.

[0047] When unlocking is required, the operator first removes the rubber anti-slip pad 13, and then moves the connecting sleeve 4. The connecting sleeve 4 drives the unlocking protrusion 251 to move, thereby driving the sliding groove block 25 to move; when the sliding groove block 25 moves, the elastic rod 27 will move upward along the forward groove 231 starting from the unlocking groove 29, and then fall into the second unlocking groove 22 under the elastic force of the spring 26. At this time, the positioning rod 28 disengages from the locking hole 31, and the insertion block 3 is in a freely movable state. Moreover, since the elastic rod 27 is in the second unlocking groove 22, the locking assembly 2 will always remain in the unlocked state, and the operator can hold the steel grating plate 1 with both hands to pull out the insertion block 3 without operating the connecting sleeve 4.

[0048] During the process of pulling out the insertion block 3, by providing an inclined guiding portion 281, the positioning rod 28 is squeezed again and moves downward, so that the insertion block 3 can be smoothly pulled out. When the positioning rod 28 moves downward, it drives the sliding groove block 25 to move, so that the elastic rod 27 moves from the second unlocking groove 22 to the first unlocking groove 21. Furthermore, the operator does not need to adjust the locking assembly 2 again. At this time, the steel grating plate 1 can be directly used for installation. Through the first unlocking groove 21 and the second unlocking groove 22, it provides great convenience for the operator when installing and disassembling the steel grating plate 1.

[0049] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the embodiments here.
