[0032] The utility model will be further described below in conjunction with the accompanying drawings.
[0033] like Figure 1 and Figure 2 As shown, the utility model provides a closed trench cover, which includes a first plate assembly 10 and a second plate assembly 20. The first plate assembly 10 is slidably connected to an inner side wall of the trench 100 in the first direction and the inner side wall of the trench 100 in the second direction; the second plate assembly 20 is arranged opposite to the first plate assembly 10 in the first direction, and is slidably connected to another inner side wall of the trench 100 in the first direction and the inner side wall of the trench 100 in the second direction; the closed trench cover is constructed such that the first plate assembly 10 and the second plate assembly 20 can be flipped in a direction close to each other to a first flip position to block the opening 101 of the trench 100, and the first plate assembly 10 and the second plate assembly 20 can be flipped in a direction away from each other to a second flip position to open the opening 101 of the trench 100, and the first plate assembly 10 and the second plate assembly 20 are stored in the trench 100.
[0034] In the above arrangement, the first plate assembly 10 and the second plate assembly 20 are arranged, and the first plate assembly 10 and the second plate assembly 20 are relatively turned over to achieve the blocking or opening of the opening 101. Moreover, while the opening 101 is opened, the first plate assembly 10 and the second plate assembly 20 are stored in the trench 100. In this way, there is no need to consider the problem of removing the first plate assembly 10 and the second plate assembly 20 after opening the opening 101 and placing them in other positions, and reassembling the first plate assembly 10 and the second plate assembly 20 on site when the opening 101 needs to be blocked, thereby eliminating the on-site disassembly and assembly procedures of the cover plate, avoiding the problem of inconvenient use of the cover plate caused by the on-site assembly method of simple wooden boards in the prior art, and thus improving the convenience of using the cover plate.
[0035] Specifically, Figure 1 and Figure 2As shown, in one embodiment, the first plate assembly 10 includes a first plate 13. One end of the first plate 13 is slidably connected to an inner wall of the trench 100 in a first direction, and the other end of the first plate 13 is slidably connected to an inner wall of the trench 100 in a second direction. Wherein, the first plate 13 flips to a first flip position or a second flip position by sliding on the inner walls of the trench 100 in the first direction and the second direction simultaneously.
[0036] In the above arrangement, the sliding connection between the first plate 13 and the inner walls of the trench 100 in the first and second directions defines the movement trajectory of the first plate 13, that is, defines the flipping trajectory of the first plate 13. Thus, it is ensured that the first plate 13 can flip to the first flip position or the second flip position, and further ensures the realization of the function of the closed trench cover.
[0037] Specifically, as Figure 1 and Figure 2 shown, in one embodiment, the first plate assembly 10 further includes a first sliding structure 11. The first sliding structure 11 is disposed between an inner wall of the trench 100 in a first direction and the first plate 13. The first plate 13 is slidably connected to an inner wall of the trench 100 in a first direction through the first sliding structure 11.
[0038] Specifically, referring to Figure 4 , in one embodiment, the first sliding structure 11 includes a first chute and a first pulley. Wherein, the first chute extends along the second direction on an inner wall of the trench 100 in a first direction; the first pulley is embedded in the first chute and pivotally connected to one end of the first plate 13. The first pulley can roll along the second direction in the first chute. In this way, the sliding connection between the first plate assembly 10 and the inner wall is realized by the rolling of the first pulley in the first chute. Thus, direct sliding contact between the first plate assembly 10 and the inner wall is avoided, thereby improving the sliding efficiency of the first plate assembly 10 and also reducing the frictional loss of the first plate assembly 10. Furthermore, the service life of the closed trench cover is extended and the cost is saved.
[0039] Specifically, as Figure 1 and Figure 2 and Figure 4 shown, in one embodiment, the first plate assembly 10 further includes a second sliding structure 12. The second sliding structure 12 is disposed between an inner wall of the trench 100 in a second direction and the first plate 13. The first plate 13 is slidably connected to an inner wall of the trench 100 in a second direction through the second sliding structure 12.
[0040] Specifically, as Figure 4As shown, in one embodiment, the second sliding structure 12 includes a second chute 121 and a second pulley 122. Among them, the second chute 121 is arranged on the inner side wall of the trench 100 in the second direction and extends along the first direction; the second pulley 122 is embedded in the second chute 121 and pivotally connected to the other end of the first plate body 13, and the second pulley 122 can roll along the first direction in the second chute 121. In this way, the sliding connection between the second plate body assembly 20 and the inner side wall is realized by the rolling of the second pulley 122 in the second chute 121. Thereby, the direct sliding contact between the second plate body assembly 20 and the inner side wall is avoided, thereby improving the sliding efficiency of the second plate body assembly 20 and also reducing the frictional loss of the second plate body assembly 20. Furthermore, the service life of the closed trench cover plate is prolonged and the cost is saved.
[0041] Specifically, as Figure 3 and Figure 4 shown, in one embodiment, the first and second chutes are T-shaped grooves.
[0042] Specifically, as Figure 1 and Figure 2 shown, in one embodiment, the trench 100 is rectangular, the first direction in this application is the width direction of the trench 100, the second direction is the length direction of the trench 100, and the third direction is the height direction of the trench 100.
[0043] Specifically, as Figure 2 shown, in one embodiment, the structure of the second plate body assembly 20 is the same as that of the first plate body assembly 10.
[0044] Further, the second plate body assembly 20 is described in detail as follows:
[0045] The second plate body assembly 20 includes a first plate body. One end of the first plate body is slidably connected to the other inner side wall of the trench in the first direction, and the other end of the first plate body is slidably connected to the inner side wall of the trench in the second direction. Among them, the first plate body slides on the inner side walls of the trench in the first direction and the second direction at the same time to flip to the first flipping position or the second flipping position.
[0046] Specifically, in one embodiment, the second plate body assembly 20 further includes a first sliding structure. The first sliding structure is arranged between one inner side wall of the trench in the first direction and the first plate body, and the first plate body is slidably connected to the other inner side wall of the trench in the first direction through the first sliding structure.
[0047] Specifically, in one embodiment, the first sliding structure includes a first chute and a first pulley. Among them, the first chute extends along the second direction and is provided on an inner sidewall of the trench in the first direction; the first pulley is embedded in the first chute and is pivotally connected to one end of the first plate body, and the first pulley can roll along the second direction in the first chute. In this way, the sliding connection between the second plate body assembly 20 and the inner sidewall is realized by the rolling of the first pulley in the first chute. Thereby, the direct sliding contact between the second plate body assembly and the inner sidewall is avoided, thereby improving the sliding efficiency of the second plate body assembly and reducing the frictional loss of the second plate body assembly at the same time. Furthermore, the service life of the closed trench cover plate is prolonged and the cost is saved.
[0048] Specifically, in one embodiment, the second plate body assembly 20 further includes a second sliding structure. The second sliding structure is arranged between the inner sidewall of the trench in the second direction and the first plate body, and the first plate body is slidably connected to the inner sidewall of the trench in the second direction through the second sliding structure.
[0049] Specifically, in one embodiment, the second sliding structure includes a second chute and a second pulley. Among them, the second chute extends along the first direction and is provided on the inner sidewall of the trench in the second direction; the second pulley is embedded in the second chute and is pivotally connected to the other end of the first plate body, and the second pulley can roll along the first direction in the second chute. In this way, the sliding connection between the second plate body assembly and the inner sidewall is realized by the rolling of the second pulley in the second chute. Thereby, the direct sliding contact between the second plate body assembly and the inner sidewall is avoided, thereby improving the sliding efficiency of the second plate body assembly and reducing the frictional loss of the second plate body assembly at the same time. Furthermore, the service life of the closed trench cover plate is prolonged and the cost is saved.
[0050] Specifically, in one embodiment, the first and second chutes are T-shaped grooves. The first pulley is confined in the first chute, and the second pulley is confined in the second chute. The first chute can prevent the first pulley from slipping out of it, and the second chute can prevent the second pulley from slipping out of it.
[0051] Specifically, as Figure 3 shown, in one embodiment, the closed trench cover plate further includes a locking assembly. The locking assembly is used to lock the first plate body assembly 10 and the second plate body assembly 20 in the first flipping position. In this way, the problem that the first plate body assembly 10 and the second plate body assembly 20 flip when the closed trench cover plate bears weight, resulting in the opening 101 not being completely blocked, is avoided.
[0052] Specifically, as Figure 3As shown, in one embodiment, the locking assembly includes a locking block 31. Two arc-shaped grooves 311 are provided on the locking block 31 at intervals. One of them is adapted to the second pulley 122 of the first plate assembly 10, and the other is adapted to the second pulley of the second plate assembly 20. A slot is provided at the opening 101. When the locking block 31 is completely inserted into the slot in the third direction, the second pulleys of the second plate assembly 20 and the first plate assembly 10 are respectively defined in the two arc-shaped grooves 311 in a one-to-one correspondence.
[0053] Specifically, as Figure 3 shown, in one embodiment, a clamping hole 312 is provided at one end of the locking block 31 exposed to the air, which facilitates taking out the locking block 31 from the jack.
[0054] As Figure 5 shown, the present utility model further provides a closed trench, which includes the above-mentioned closed trench cover plate and a staircase 40. Among them, the staircase 40 is arranged in the trench 100 and is located below the closed trench cover plate; among them, the staircase 40 is respectively arranged at both ends of the trench 100 in the second direction, and there are gaps between both sides of the staircase 40 in the first direction and the two inner side walls of the corresponding trench 100 in the first direction (one side of the staircase 40 is adjacent to the inner side wall of the trench 100). When the opening 101 of the trench 100 is opened, the first plate assembly 10 and the second plate assembly 20 slide into the corresponding gaps to avoid interference between the staircase 40 and the first plate assembly 10 and the second plate assembly 20, so as to prevent the situation that the first plate assembly 10 and the second plate assembly 20 cannot be stored in the trench 100.
[0055] Specifically, as Figure 5 shown, in one embodiment, the staircase 40 includes a plurality of steps 41 stacked in sequence in the third direction. One ends of the plurality of steps 41 are all connected to the inner side wall of the trench 100 in the second direction, and the other ends and both sides of the plurality of steps 41 are sequentially indented from bottom to top in the third direction. Two gaps are formed between both sides of the plurality of steps 41 and the two inner side walls of the corresponding trench 100 in the first direction. The first plate assembly 10 can be placed in one of the two gaps, and the second plate assembly 20 can be placed in the other gap.
