Description

Technical Field

[0001] This utility model relates to the field of drainage cover technology, specifically a multi-slot cover for use in drainage ditches. Background Technology

[0002] Linear drainage ditch covers originated in Europe. After many years of iteration, today's linear drainage ditch covers mainly adopt slotted linear drainage ditch covers, which are further divided into single-slot and multi-slot covers.

[0003] The multi-slot cover is mainly composed of support plates on both sides and multiple vertical plates set in the middle of the support plates. The multiple vertical plates are spaced apart and form multiple slots for drainage. The multiple vertical plates are all welded to the support plates. However, in the traditional way, the vertical plates are manually fixed and welded. Due to the limitation of the small gaps, welding is difficult. At the same time, manual positioning is inaccurate and errors are easy to occur, which seriously affects the appearance. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-8 As shown, the present invention provides a multi-slot cover for use in drainage ditches, comprising a support plate 1, at least one positioning member 2, and multiple support uprights 3.

[0028] The support plate 1 has a slot 11 along a first direction. Preferably, the support plate 1 is rectangular and the slot 11 is rectangular. It should be understood that the first direction is the length direction of the slot 11.

[0029] At least one positioning element 2 is spaced apart in the slot 11 along the first direction. That is, multiple positioning elements 2 are spaced apart along the length of the slot 11.

[0030] Multiple support plates 3 are spaced apart in the slot 11 and vertically arranged on the top surface of the support plate 1, wherein a drainage groove 30 is formed between each pair of support plates 3 for drainage. It should be understood that the multiple support plates 3 are arranged along the width direction of the slot 11.

[0031] In this embodiment, the positioning member 2 is provided with at least one first locking groove 21 at intervals along the second direction, and the supporting plate 3 is locked in the first locking groove 21, and the first direction is perpendicular to the second direction.

[0032] In other words, the positioning component 2 is provided with multiple first locking slots 21 at intervals along the second direction, and the size of each first locking slot 21 is the same, that is, the distance between any two adjacent first locking slots 21 is also the same, so that the multiple supporting uprights 3 are evenly spaced, and the size of the multiple drainage gaps 30 formed by the multiple supporting uprights 3 is also the same, so that the appearance is beautiful.

[0033] Of course, in other embodiments, the positioning member 2 is provided with a plurality of first locking grooves 21 at different distances along the second direction, so that multiple supporting uprights 3 can form multiple drainage gaps 30 of different sizes.

[0034] In this embodiment, the multiple supporting uprights 3 include a first outer upright 31, a second outer upright 32, and at least one central upright 33. The first outer upright 31 is disposed on one side of the slot 11 and on one side of the positioning member 2, the second outer upright 32 is disposed on the other side of the slot 11 and on the other side of the positioning member 2, and the central upright 33 is disposed in the first locking groove 21. That is, by adding a central upright 33 to the first locking groove 21 of the positioning member 2, the number of drainage grooves of the multi-groove cover can be increased.

[0035] In another embodiment, the first outer vertical plate 31 can be integrally formed with one side of the slot 11 of the support plate 1 by bending, and the second outer vertical plate 32 can be integrally formed with the other side of the slot 11 of the support plate 1 by bending, thereby making the subsequent assembly of the positioning component 2 more convenient.

[0036] Furthermore, the positioning component 2 is rectangular in shape, with a first locking groove 21 located at the top of the positioning component 2 and a second locking groove 331 located at the bottom of the central plate 33. The central plate 33 is locked into the first locking groove 21 of the positioning component 2 through the second locking groove 331. It should be understood that the vertical length of the second locking groove 331 of the central plate 33 is equal to the vertical length from the bottom surface of the first locking groove 21 of the positioning component 2 to the bottom surface of the positioning component 2. This allows the central plate 33 to be completely locked into the positioning component 2, so that when the central plate 33 needs to be welded and fixed manually, the central plate 33 will be firmly accepted for welding without moving. This also reduces the need for manual support of the central plate 33 during welding. At the same time, the tops of the central plate 33 and the positioning component 2 are on the same plane, making the appearance of the multi-slot cover more aesthetically pleasing.

[0037] Furthermore, the first outer upright plate 31 is provided with a third locking groove 311, and the second outer upright plate 32 is provided with a fourth locking groove 321. The positioning member 2 has a first extension 22 that is locked in the third locking groove 311 and a second extension 23 that is locked in the fourth locking groove 321 on both sides. It should be understood that after the middle upright plate 33 is installed into the first locking groove 21 of the positioning member 2, the first extension 22 of the positioning member 2 can be inserted into the third locking groove 311, and the second extension 23 can be inserted into the fourth locking groove 321, thus quickly assembling the entire assembly using a mortise and tenon joint. Then, the supporting upright plate 3 can be welded. The assembled supporting upright plate 3 can be welded directly without support, which greatly reduces the manual labor previously required for welding, thereby indirectly reducing labor costs.

[0038] Preferably, the slot 11 is long rectangular, the first outer vertical plate 31, the second outer vertical plate 32 and the middle vertical plate 33 are all long rectangular, the first extension 22 and the second extension 23 are both rectangular, the first locking slot 21, the second locking slot 331, the third locking slot 311 and the fourth locking slot 321 are all rectangular, wherein the first locking slot 21 and the second locking slot 331 are slots with openings, the third locking slot 311 and the fourth locking slot 321 are slots without openings, and the length of the first locking slot 21 is longer than the length of the second locking slot 331.

[0039] It is understandable that since the first outer upright plate 31 and the second outer upright plate 32 are connected to the support plate 1 in advance, and the third locking groove 311 is a non-holeed groove that does not communicate with the top surface or bottom section of the first outer upright plate 31, and the fourth locking groove 331 is a non-holeed groove that does not communicate with the top surface or bottom section of the second outer upright plate 32, the positioning member 2 will not wobble when connected between the first outer upright plate 31 and the second outer upright plate 32. In addition, the length of the first extension 22 is equal to the thickness of the first outer upright plate 31, and the length of the second extension 23 is also equal to the thickness of the second outer upright plate 32. In this way, when the positioning member 2 is connected to the slot 11, no part will protrude from the outside of the multiple support upright plates 3, making the multi-slot cover plate appear more regular.

[0040] In this embodiment, the multi-slot cover plate applied to the drainage ditch also includes a limiting block 4, wherein the limiting block 4 is disposed at one end of the slot 11.

[0041] Preferably, there are two limiting blocks 4, which are respectively disposed at both ends of the slot 11. It should be understood that the limiting blocks 4 can limit and fix the two ends of the multiple supporting uprights 3.

[0042] Furthermore, the limiting block 4 has multiple locking slots, wherein the first outer vertical plate 31, the second outer vertical plate 32 and the middle vertical plate 33 all extend with locking blocks 34 corresponding to the locking slots and locked in the locking slots.

[0043] In this embodiment, the limiting block 4 is rectangular in shape, and has multiple locking slots including a first locking slot 41, a second locking slot 42, and at least one third locking slot 43. The first locking slot 41 and the second locking slot 42 are respectively located at the two ends of the limiting block 4 and are open slots. The third locking slot 43 is located inside the limiting block 4. The first outer upright plate 31 is locked in the first locking slot 41 by its locking block 34, the second outer upright plate 32 is located in the second locking slot 42 by its locking block 34, and the middle upright plate 33 is located in the third locking slot 43 by its locking block 34. That is to say, the limiting block 4 firmly limits the multiple supporting upright plates 3 within the slot 11.

[0044] Furthermore, the bottom surface of the support plate 1 is provided with multiple support members 5 at intervals along the second direction. The support members 5 are correspondingly located at the limiting block 4 and the positioning member 2, and are all connected to the limiting block 4 and the positioning member 2. It should be understood that the multi-slot cover is located at the drainage ditch, and only the surfaces of the multiple support uprights 3 are on the same plane as the ground. The rest of the support plates 1 are below the ground. When heavy objects such as vehicles pass over the multi-slot cover, the multiple support uprights 3 will be subjected to the pressure of the vehicle. The multiple support members 5 located on the bottom surface of the support plate 1 will buffer this pressure through deformation. The support members 5 are respectively located below and connected to the limiting block 4 and the positioning member 2. At the same time, because the multiple support uprights 3 and the positioning member 2 are connected by a mortise and tenon structure, the load-bearing capacity of the multi-slot cover is stronger and the service life is longer. At the same time, the support members 5 will not block the drainage seams 30 and will not affect drainage.

[0045] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
