Description

Technical Field

[0001] This application relates to the field of trench cover technology, and in particular to a trench cover. Background Technology

[0002] Trench covers, made of steel grating, are available in various models to suit different span loads and requirements. They are widely used in municipal roads, landscaping, residential areas, schools, stadiums, and other locations. Depending on the application, different specifications of trench covers can be hot-dip galvanized, cold-galvanized (electroplated), or left untreated. Trench covers are mainly used in factories and upscale residential areas, primarily because concrete trench covers are frequently crushed, damaging the road surface. Therefore, trench covers made of steel grating are suitable for different load-bearing capacities.

[0003] Regarding the aforementioned technologies, trench covers are generally laid flat on the ditch to cover it. They can be separated from the ditch by simply lifting them manually. However, since trench covers are made of steel grating, they are easily stolen. Summary of the Invention

[0004] In order to prevent theft of trench covers and reduce the occurrence of trench cover theft, this application provides a trench cover.

[0005] The trench cover provided in this application adopts the following technical solution:

[0006] A trench cover includes a top cover, with support plates on both sides of the top cover. Each support plate has a clamping assembly on both sides, which cooperate to clamp the top cover and the support plates between the trench side walls. The support plates also include an adjusting assembly for adjusting the clamping assemblies, and an adjusting hole for adjusting the adjusting assembly. Finally, a closing assembly for closing the adjusting hole is provided within the support plates.

[0007] By adopting the above technical solution, the top cover and support plate are placed together in the trench. Then, the adjustment component is adjusted through the adjustment hole. The adjustment component drives the clamping component to press against the inner wall of the trench, so that the top cover and support plate are fixed between the trench. Then, the closing component is adjusted to close the adjustment hole, preventing thieves from adjusting the adjustment component themselves. This makes it difficult for thieves to remove the trench cover from the trench, thus strengthening the anti-theft function of the trench cover.

[0008] Optionally, the clamping assembly includes a first push rod, which is slidably disposed within the support plate. The first push rod is connected to a clamping rod, which is connected to a clamping head. The support plate has a first movable opening for the clamping head to extend out of or into the support plate. The adjusting assembly controls the sliding of the first push rod.

[0009] By adopting the above technical solution, the adjusting component pushes the first push rod, which drives the clamping rod to approach the inner wall of the trench. The clamping rod drives the clamping head to extend from the first movable opening and clamp the inner wall of the trench. Both inner walls of the trench are clamped by the clamping head, thereby securing the support plate and the top cover between the two side walls of the trench.

[0010] Optionally, the adjusting assembly includes a rotating rod that is threadedly connected to the adjusting hole. The rotating rod is rotatably connected to a connecting rod, which is connected to a lifting plate. The lifting plate is slidably connected to the inner wall of the support plate. The lifting plate is located above the first push rod, and the lifting plate is hinged to a second push rod, which is hinged to the first push rod.

[0011] By adopting the above technical solution, the rotating rod is rotated with a tool, and the rotating rod gradually extends into the adjustment hole. The rotating rod drives the connecting rod to descend, the connecting rod drives the lifting plate to descend, the lifting plate drives the second push rod to descend and rotate, and the second push rod gradually pushes the first push rod to move towards the first movable opening.

[0012] Optionally, the closing assembly includes a plurality of rotating wheels, which are rotatably disposed within the support plate and are equidistantly arranged along the circumference of the adjustment hole. Each rotating wheel is connected to a shielding plate, and the ends of adjacent shielding plates away from the rotating wheels overlap each other. The ends of the shielding plates away from the rotating wheels together close the adjustment hole. The support plate is provided with a first linkage for driving the plurality of rotating wheels to rotate simultaneously.

[0013] By adopting the above technical solution, the first linkage is adjusted to drive several rotating wheels to rotate. The rotating wheels drive their blocking plates to rotate and cause the end of the blocking plate away from the rotating wheel to extend into the adjustment hole. The ends of adjacent blocking plates away from the rotating wheel overlap each other. All the blocking plates cooperate to close the adjustment hole. Thieves need to destroy all the blocking plates in order to insert tools into the adjustment hole for adjustment, thus making it difficult for thieves to steal this type of trench cover and further strengthening the anti-theft function.

[0014] Optionally, the first linkage includes a fixed plate disposed on the rotating wheel, a drive shaft rotatably connected inside the support plate, one end of the drive shaft extending out or flush with the top surface of the support plate, a traction rope being wound around the drive shaft and several rotating wheels, and several fixed plates being fixed to the traction rope.

[0015] By adopting the above technical solution, the drive shaft is adjusted, and the drive shaft drives the traction rope to move. The traction rope drives several rotating wheels to rotate simultaneously, so that several blocking plates can rotate at the same time and seal the plate adjustment hole.

[0016] Optionally, two guide wheels are rotatably connected inside the support plate, the drive shaft is located between the two guide wheels, and the traction rope passes sequentially around one of the guide wheels, the drive shaft, and the other guide wheel.

[0017] By adopting the above technical solution, the guide wheel guides the traction rope, increases the contact area between the traction rope and the drive shaft, and makes it easier for the drive shaft to drive the traction rope.

[0018] Optionally, the drive shaft is provided with a screw groove, which is hexagonal in shape.

[0019] By adopting the above technical solution, the groove is designed as a non-standard groove, so special tools are needed to adjust the rotation of the cover plate, which improves the anti-theft function of this type of trench cover.

[0020] Optionally, the top cover has an installation groove for placing a filter plate, and the support plate has a movable groove on the side near the top cover. The filter plate is connected to a sliding block located in the movable groove. The top cover and the filter plate can move away from or close to each other. A support rod is provided inside the support plate, and a second linkage is connected to the support rod. The support plate has a second movable opening. When the filter plate moves away from the top cover, the second linkage drives the support rod to extend out of the second movable opening and press against the side wall of the trench.

[0021] By adopting the above technical solution, when a thief tries to forcibly remove the trench cover, the thief needs to lift the filter plate, which is installed on the top cover. At this time, the filter plate is lifted and moves away from the cover. The lifting of the filter plate drives the second linkage to move. The second linkage drives the support rod to extend out of the second movable opening and press against the side wall of the trench, making the top cover and the support plate more secure between the two side walls of the trench, further making it difficult for the thief to remove the top cover and the support plate from the trench.

[0022] Optionally, the second connecting member includes a first rack and a second rack, both of which are slidably connected within the support plate. The sliding block is connected to the first rack, and the support plate is rotatably connected to a gear. The first rack and the second rack are arranged opposite to each other, and the gear is located between the first rack and the second rack. The gear meshes with both the first rack and the second rack simultaneously. The second rack is located above the support rod, and a connecting rod is hinged to the second rack. The connecting rod is hinged to the support rod.

[0023] By adopting the above technical solution, when the filter plate moves upward, the sliding block drives the first rack to rise, the first rack drives the gear to rotate, the gear drives the second rack to fall, the second rack drives the connecting rod to fall and rotate, and the end of the connecting rod push rod support rod away from the second rack extends out of the second movable opening and abuts against the side wall of the trench.

[0024] Optionally, a filtration space is provided between the top cover and the filter plate, and the filter holes of the filter plate and the top cover are arranged alternately.

[0025] By adopting the above technical solution, the filter holes of the top cover and the filter plate are arranged in an alternating manner, which prevents thieves from simultaneously inserting clamping tools into the filter holes of the top cover and the filter plate, thus preventing thieves from lifting the top cover and the filter plate at the same time, thereby further enhancing the anti-theft function of the trench cover.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the top cover and support plate together into the trench, then adjust the adjustment component through the adjustment hole. The adjustment component will drive the clamping component to press against the inner wall of the trench, so that the top cover and support plate are fastened between the trench. Then adjust the sealing component to seal the adjustment hole, preventing thieves from adjusting the adjustment component themselves, making it difficult for thieves to remove the trench cover from the trench, thus strengthening the anti-theft function of the trench cover.

[0028] 2. Adjusting the first linkage drives several rotating wheels to rotate, which in turn drives their blocking plates to rotate and cause the end of the blocking plate away from the rotating wheel to extend into the adjustment hole. The ends of adjacent blocking plates away from the rotating wheel overlap each other, and all the blocking plates cooperate to close the adjustment hole. Thieves need to destroy the left and right blocking plates in order to insert tools into the adjustment hole to make adjustments, thus making it difficult for thieves to steal this type of trench cover and further strengthening the anti-theft function.

[0029] 3. When a thief attempts to forcibly remove the trench cover, a filter plate is installed above the top cover. The thief needs to lift the filter plate, which then moves away from the cover. This movement causes the second linkage to extend from the top cover and press against the side wall of the trench, making the top cover and the support plate more secure between the two sides of the trench. This further makes it difficult for the thief to remove the top cover and the support plate from the trench. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a trench cover.

[0037] like Figure 1 and Figure 2 The trench cover includes a top cover 1, and support plates 2 are fixedly connected to both sides of the top cover 1. The support plates 2 are integrally formed with the top cover 1. The top surface of the top cover 1 has an installation groove 11. The support plate 2 has a movable groove 21 on the side facing the top cover 1. Both movable grooves 21 are connected to the installation groove 11. A filter plate 3 is installed in the installation groove 11. Sliding blocks 31 are fixed on both sides of the filter plate 3. The sliding blocks 31 are located in the installation groove 11 on the same side, and the end of the sliding block 31 away from the filter plate 3 extends into the support plate 2. The filter holes of the filter plate 3 are staggered with the filter holes of the top cover 1. A water filtration space is left between the filter plate 3 and the top cover 1. The top surface of the filter plate 3 is flush with the top surface of the support plate 2.

[0038] like Figure 2 and Figure 3 The support plate 2 is provided with a clamping component 4. The clamping components 4 of the two support plates 2 clamp against the side wall of the trench on the same side, so that the top cover 1 and the support plate 2 are fastened between the two side walls of the trench. The support plate 2 is provided with an adjustment component 5 for adjusting the clamping component 4. The top surface of the support plate 2 is provided with an adjustment hole 22 for operating the adjustment component 5. The support plate 2 is provided with a closing component 6 for closing the adjustment hole 22.

[0039] Two support rods 7 are slidably connected inside the support plate 2. The clamping assembly 4 is located between the two support rods 7. The support plate 2 has two second movable openings 24 for the support rods 7 to extend out of the support plate 2. The second movable openings 24 correspond one-to-one with the support rods 7. A second linkage 9 is provided inside the support plate 2, and the sliding block 31 is connected to the second linkage 9. When the filter plate 3 moves away from the top cover 1, the filter plate 3 drives the second linkage 9 to control the corresponding support rod 7 to extend out of the second movable opening 24 and clamp against the side wall of the trench.

[0040] When installing the trench cover, the top cover 1 and the support plate 2 are placed into the trench together. Then, the adjustment component 5 is adjusted through the adjustment hole 22. The adjustment component 5 drives the clamping component 4 to press against the inner wall of the trench, so that the top cover 1 and the support plate 2 are fastened between the trench. Then, the closing component 6 is adjusted to close the adjustment hole 22 to prevent thieves from adjusting the adjustment component 5 by themselves, making it difficult for thieves to remove the trench cover from the trench.

[0041] When a thief attempts to forcibly remove the trench cover, the thief needs to lift the filter plate 3, which is installed above the top cover 1. At this time, the filter plate 3 is raised and moves away from the top cover 1. The lifting of the filter plate 3 drives the second linkage 9 to move. The second linkage 9 drives the support rod 7 to extend out of the second movable opening 24 and press against the side wall of the trench, making the top cover 1 and the support plate 2 more secure between the two side walls of the trench. This further makes it difficult for thieves to remove the top cover 1 and the support plate 2 from the trench, thus improving the anti-theft function of the trench cover.

[0042] like Figure 2 The clamping component 4 includes a first push rod 41, which is slidably connected to the bottom of the support plate 2. The support plate 2 has a first movable opening 23 on the side away from the top cover 1. The first push rod 41 is connected to a clamping rod 42. The end of the clamping rod 42 away from the first push rod 41 is connected to a clamping head 43, which is directly opposite the first movable opening 23.

[0043] The adjustment assembly 5 includes a rotating rod 51, which is threadedly connected to the adjustment hole 22. The rotating rod 51 is rotatably connected to a connecting rod 52. A lifting plate 53 is slidably connected to the side of the support plate 2 near the top cover 1. One side of the lifting plate 53 is fixedly connected to the rotating rod 51. The lifting plate 53 is located above the first push rod 41. A second push rod 54 is hinged to the side of the support plate 2 facing the first movable opening 23. The second push rod 54 is hinged to the top of the first push rod 41.

[0044] Rotate the rotating rod 51 with a tool. The rotating rod 51 gradually extends into the adjusting hole 22. The rotating rod 51 drives the connecting rod 52 to descend. The connecting rod 52 drives the lifting plate 53 to descend. The lifting plate 53 drives the second push rod 54 to descend and rotate. The second push rod 54 gradually pushes the first push rod 41 to move towards the first movable opening 23. The first push rod 41 drives the clamping rod 42 to approach the inner wall of the trench. The clamping rod 42 drives the clamping head 43 to extend from the first movable opening 23 and clamp against the inner wall of the trench. Both inner walls of the trench are clamped by the clamping head 43, thereby securing the support plate 2 and the top cover 1 between the two inner walls of the trench.

[0045] like Figure 4 The enclosed assembly 6 includes several rotating wheels 61, which are rotatably disposed in the inner top wall of the support plate 2. The rotating wheels 61 are equidistantly arranged along the circumference of the adjustment hole 22. Each rotating wheel 61 is connected to a shielding plate 62. The ends of adjacent shielding plates 62 away from the rotating wheel 61 overlap each other. The support plate 2 is provided with a first linkage 8 for driving several rotating wheels 61 to rotate simultaneously.

[0046] Before the rotating rod 51 is adjusted, the blocking plate 62 is separated from the adjustment hole 22. The rotating rod 51 is located between several blocking plates 62. After the rotating rod 51 is adjusted, the first linkage 8 drives the rotating wheel 61 to rotate. The rotating wheel 61 drives the blocking plates 62 to rotate into the adjustment hole 22. The ends of adjacent blocking plates 62 away from the rotating wheel 61 overlap each other. All the blocking plates 62 cooperate to close the adjustment hole 22. The rotating rod 51 is located below the blocking plates 62. Thieves need to destroy all the blocking plates 62 before they can insert tools into the adjustment hole 22 to adjust the rotating rod 51. This makes it difficult for thieves to steal this type of trench cover and further strengthens the anti-theft function.

[0047] like Figure 4 The first linkage 8 includes a fixed plate 81 fixed on the rotating wheel 61. The inner top wall of the support plate 2 is rotatably connected to a drive shaft 82. The top surface of the drive shaft 82 is flush with the top surface of the support plate 2. The top surface of the drive shaft 82 is provided with a screw groove 821, which is hexagonal. Two guide wheels 83 are rotatably connected inside the inner top wall of the support plate 2. The drive shaft 82 is located between the two guide wheels 83. A traction rope 63 is wound on the drive shaft 82. The traction rope 63 starts from the drive shaft 82, passes around one guide wheel 83, several fixed plates 81 and another guide wheel 83 in sequence, and finally returns to the drive shaft 82 to form a closed loop. Each fixed plate 81 is fixed to the traction rope 63.

[0048] The groove 821 is designed as a non-standard groove, so a special tool is needed to control the rotation of the baffle plate 62. The special tool is used to rotate the drive shaft 82, and the guide wheel 83 guides the traction rope 63, increasing the contact area between the traction rope 63 and the drive shaft 82. The drive shaft 82 drives the traction rope 63 to move, and the traction rope 63 drives several rotating wheels 61 to rotate at the same time, so that several baffle plates 62 can rotate at the same time and seal the plate adjustment hole 22.

[0049] like Figure 3 The second linkage 9 includes a first rack 91 and a second rack 92. The first rack 91 is fixed to the bottom of the sliding block 31 extending into one end of the support plate 2. The second rack 92 is slidably connected to the side of the support plate 2 near the top cover 1. A gear 93 is rotatably connected to the side of the support plate 2 near the top cover 1. The gear 93 is located between the first rack 91 and the second rack 92. The first rack 91 and the second rack 92 are arranged opposite to each other and both the first rack 91 and the second rack 92 mesh with the gear 93. The second rack 92 is located above the support rod 7. A connecting rod 94 is hinged to one side of the second rack 92. The end of the connecting rod 94 away from the second rack 92 is hinged to the support rod 7.

[0050] When the filter plate 3 moves upward, the sliding block 31 drives the first rack 91 to rise, the first rack 91 drives the gear 93 to rotate, the gear 93 drives the second rack 92 to fall, the second rack 92 drives the connecting rod 94 to fall and rotate, the end of the connecting rod 94 push rod support rod 7 away from the second rack 92 extends out of the second movable opening 24 and abuts against the side wall of the trench, making the top cover 1 and the support plate 2 more secure between the two side walls of the trench, further making it difficult for thieves to remove the top cover 1 and the support plate 2 from the trench.

[0051] The implementation principle of this application embodiment is as follows: the top cover 1 and the support plate 2 are placed into the trench together, and then the adjustment component 5 is adjusted through the adjustment hole 22. The adjustment component 5 drives the clamping component 4 to clamp against the inner wall of the trench, so that the top cover 1 and the support plate 2 are fixed between the trench. Then the closing component 6 is adjusted to close the adjustment hole 22, preventing thieves from adjusting the adjustment component 5 by themselves, making it difficult for thieves to remove the trench cover from the trench, thus strengthening the anti-theft function of the trench cover.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
