Description

Technical Field

[0001] The embodiments of this utility model relate to the field of drainage ditch technology, specifically to a reinforced concrete narrow-slot drainage ditch and its processing mold. Background Technology

[0002] Reinforced concrete drainage ditches are drainage facilities constructed using reinforced concrete materials. Compared to traditional concrete drainage ditches, reinforced concrete drainage ditches have the following characteristics: high strength, capable of withstanding greater pressure and loads, and not easily deformed or damaged; good corrosion resistance, not easily eroded by water or air in the environment, and a longer service life; convenient construction, as they can be designed and manufactured according to actual needs; and convenient maintenance, with relatively simple cleaning and upkeep.

[0003] Currently, the overall drainage effect of reinforced concrete drainage ditches on the market is not good enough, and it is troublesome to connect multiple drainage ditches. The sealing effect at the connection is poor, which is not conducive to daily use. Furthermore, the efficiency of mass production is low, the labor cost is high, and it is difficult to meet market demand. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a reinforced concrete narrow-slot drainage ditch and processing mold, which solves the technical problems of the inconvenience of connecting multiple drainage ditches and the poor sealing effect at the joints in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a reinforced concrete joint drainage ditch and processing mold, comprising: a drainage ditch body, wherein a through groove is provided inside the drainage ditch body, a connecting groove is provided at the front end of the drainage ditch body, an inclined groove is provided at the top of the drainage ditch body, and a connecting ring is fixedly connected to the rear end of the drainage ditch body.

[0006] A processing mold for a reinforced concrete fine-joint drainage ditch includes: a base and two sets of side plates. Two sets of end plates are slidably connected to the top of the base. A bottom plate is fixedly connected to the top of the base. Connecting shafts are provided at both the front and rear ends of the bottom plate. Side plates are rotatably connected to both the front and rear ends of the bottom plate via connecting shafts. A sliding plate is slidably connected to the inner side of the base. A fixing frame is fixedly connected to the top of the sliding plate. An inner core is fixedly connected to the side of the fixing frame. A rotating shaft is rotatably connected inside the inner core. A lifting plate is slidably connected inside the inner core. A lifting assembly is provided inside the inner core. Fastening mechanisms are provided at both the front and rear ends of the end plates. The lifting assembly includes a rotating frame, a connecting piece, a lifting component, and an annular component. The rotating frame is fixedly connected to the surface of the rotating shaft. The annular component is fixedly connected to the inner wall of the inner core. An annular groove is fixedly connected to the inner side of the annular component. The top of the lifting component is fixedly connected to the bottom of the lifting plate. The end of the lifting component away from the lifting plate is slidably connected to the annular groove. Both ends of the connecting piece are rotatably connected to the rotating frame and the lifting component, respectively.

[0007] For example, in a processing mold for a reinforced concrete narrow-slot drainage ditch provided in at least one embodiment of the present invention, an embedded block is fixedly connected to the top of the base plate, and the diameter of the inner core is equal to the diameter of the through groove.

[0008] The diameter of the connecting ring is equal to the diameter of the connecting groove. A sealing ring groove is provided on the surface of the connecting ring. The connection is made by inserting the rear connecting ring of the first set of drainage ditch bodies into the front connecting groove of the second set of drainage ditch bodies. A sealing ring can be set in the sealing groove.

[0009] The end of the rotating shaft away from the inner core is connected to the fixing frame through and rotates, and the end of the rotating shaft away from the inner core is provided with an anti-slip block, which allows the rotating shaft to be rotated manually.

[0010] The inclined channel is trapezoidal in shape and is connected to the through channel, allowing water to flow through the trapezoidal inclined channel into the through channel.

[0011] According to another aspect, at least one embodiment of the present invention also provides a fastening mechanism, comprising: a fixing block and a limiting block, wherein the fixing block is fixedly connected to an end plate, a connecting frame is fixedly connected to the bottom of the fixing block, a rotating column is rotatably connected to the inner side of the connecting frame, a vertical rod is fixedly connected to the bottom of the rotating column, a limiting column is fixedly connected to the bottom of the vertical rod, the limiting block is fixedly connected to a side plate, a limiting groove is formed at the bottom of the limiting block, a groove is formed inside the limiting groove, a telescopic spring is provided inside the groove, an arc-shaped block is elastically connected inside the groove through the telescopic spring, and a pull rod is fixedly connected to one end of the arc-shaped block near the telescopic spring.

[0012] For example, in at least one embodiment of the present invention, the fastening mechanism further includes: the width of the limiting groove is equal to the diameter of the limiting post, the limiting groove is U-shaped, and the limiting post can enter the limiting groove.

[0013] The arc surface of the arc block faces the bottom of the limiting groove, and half of the arc block protrudes out of the groove in the initial state. When the arc surface of the arc block is squeezed, it will move into the groove.

[0014] The depth of the groove is greater than the length of the arc-shaped block. The pull rod and the limiting block pass through and are slidably connected. The arc-shaped block can be completely retracted into the groove. The pull rod can be used to pull the arc-shaped block into the groove.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] This invention reduces the manpower required for the production of the drainage ditch body by using components such as end plates, bottom plates, side plates, and sliding plates. The lifting components make it easier to move the inner core out when demolding the drainage ditch body. The connecting rings and connecting grooves make it easier to connect multiple units of the drainage ditch body, resulting in better overall drainage performance.

[0017] In this invention, the fastening mechanism allows the two sets of end plates to be moved to abut against the side plates and bottom plates to form a complete mold. The vertical rod can then be rotated to allow the limiting post to enter the limiting groove. With the cooperation of components such as the arc block and the groove, the limiting post can no longer move downwards and leave the limiting groove. This allows the two sets of end plates to be firmly joined with the side plates and bottom plates. When separation is required, pulling the pull rod will allow the arc block to retract into the groove and no longer prevent the limiting post from leaving, making it more convenient to use.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-8 As shown, it illustrates a reinforced concrete narrow-slot drainage ditch in one embodiment of the present invention. The drainage ditch body 1 has a through groove 2 inside, a connecting groove 3 at the front end, an inclined groove 4 at the top, and a connecting ring 5 fixedly connected to the rear end of the drainage ditch body 1.

[0035] A processing mold for a reinforced concrete narrow-slot drainage ditch includes: a base 7 and two sets of side plates 911. Two sets of end plates 8 are slidably connected to the top of the base 7. A bottom plate 9 is fixedly connected to the top of the base 7. Connecting shafts 10 are provided at both the front and rear ends of the bottom plate 9. The front and rear ends of the bottom plate 9 are rotatably connected to the side plates 11 via the connecting shafts 10. A sliding plate 13 is slidably connected to the inner side of the base 7. A fixing frame 14 is fixedly connected to the top of the sliding plate 13. An inner core 15 is fixedly connected to the side of the fixing frame 14. A rotating shaft 16 is rotatably connected inside the inner core 15. A lifting plate 20 is slidably connected inside the inner core 15. A lifting assembly 18 is provided, and fastening mechanisms 19 are provided at both the front and rear ends of the end plate 8. The lifting assembly 18 includes a rotating frame 181, a connecting piece 182, a lifting piece 183, and an annular piece 184. The rotating frame 181 is fixedly connected to the surface of the rotating shaft 16, the annular piece 184 is fixedly connected to the inner wall of the inner core 15, and an annular groove 185 is fixedly connected to the inner side of the annular piece 184. The top of the lifting piece 183 is fixedly connected to the bottom of the lifting plate 20, and the end of the lifting piece 183 away from the lifting plate 20 is slidably connected to the annular groove 185. The two ends of the connecting piece 182 are rotatably connected to the rotating frame 181 and the lifting piece 183, respectively.

[0036] In some examples, the top of the base plate 9 is fixedly connected to an embedded block 12, and the diameter of the inner core 15 is equal to the diameter of the through groove 2.

[0037] The diameter of the connecting ring 5 is equal to the diameter of the connecting groove 3. A sealing ring groove 6 is provided on the surface of the connecting ring 5. The connection is made by inserting the rear connecting ring 5 of the first set of drainage ditch body 1 into the front connecting groove 3 of the second set of drainage ditch body 1. A sealing ring can be set in the sealing ring groove 6.

[0038] The end of the rotating shaft 16 away from the interior of the inner core 15 is connected to the fixing frame 14 through and rotatably. The end of the rotating shaft 16 away from the interior of the inner core 15 is provided with an anti-slip block, which allows the rotating shaft 16 to be rotated manually.

[0039] The inclined channel 4 is trapezoidal in shape and is connected to the through channel 2. Water can flow into the through channel 2 through the trapezoidal inclined channel 4.

[0040] For example, as shown in the figure, the assembly of multiple drainage ditch bodies 1 is completed by inserting the rear connecting ring 5 of the first drainage ditch body 1 into the front connecting groove 3 of the second drainage ditch body 1. A sealing ring can be set in the sealing ring groove 6 to improve the sealing of the overall assembly. Water can flow into the through groove 2 through the trapezoidal inclined groove 4 for drainage. When producing the drainage ditch body 1, the two end plates 8 are moved close together to merge with the side plate 11 and the bottom plate 9, and the fixed frame 14 is pushed to move the sliding plate 13 and the inner core 15, so that the inner core 15 is inserted into the mold to form a complete mold. Then concrete is poured into the mold. When demolding is required after the whole is formed, the rotating shaft 16 can be manually rotated through the anti-slip block. The rotation of the rotating shaft 16 will drive the lifting plate 20 to descend through the cooperation of the rotating frame 181, the connecting piece 182, the lifting piece 183 and the ring piece 184, so that the inner core 15 is loosened from the formed drainage ditch body 1, making it easy to remove the inner core 15.

[0041] like Figures 1-8 As shown, a fastening mechanism 19 in another embodiment of the present invention is illustrated, comprising: a fixing block 191 and a limiting block 196. The fixing block 191 is fixedly connected to the end plate 8. A connecting frame 192 is fixedly connected to the bottom of the fixing block 191. A rotating column 193 is rotatably connected to the inner side of the connecting frame 192. A vertical rod 194 is fixedly connected to the bottom of the rotating column 193. A limiting post 195 is fixedly connected to the bottom of the vertical rod 194. The limiting block 196 is fixedly connected to the side plate 11. A limiting groove 197 is formed at the bottom of the limiting block 196. A groove 198 is formed inside the limiting groove 197. A telescopic spring 199 is provided inside the groove 198. An arc-shaped block 1910 is elastically connected inside the groove 198 through the telescopic spring 199. A pull rod 1911 is fixedly connected to one end of the arc-shaped block 1910 near the telescopic spring 199.

[0042] In some examples, the width of the limiting groove 197 is equal to the diameter of the limiting post 195, the limiting groove 197 is U-shaped, and the limiting post 195 can enter the limiting groove 197.

[0043] The arc surface of the arc block 1910 faces the bottom of the limiting groove 197, and half of the arc block 1910 protrudes from the groove 198 in the initial state. When the arc surface of the arc block 1910 is squeezed, it will move into the groove 198.

[0044] The depth of the groove 198 is greater than the length of the arc block 1910. The pull rod 1911 and the limiting block 196 pass through and are slidably connected. The arc block 1910 can be completely retracted into the groove 198. The pull rod 1911 can pull the arc block 1910 into the groove 198.

[0045] For example, as shown in the figure, when the two sets of end plates 8 are moved closer together to merge with the side plate 11 and the bottom plate 9, the vertical rod 194 can be rotated to allow the limiting post 195 to enter the limiting groove 197. Initially, the arc surface of the arc block 1910 is squeezed and retracts into the groove 198, and the telescopic spring 199 is compressed. When the limiting post 195 crosses the groove 198, the telescopic spring 199 rebounds and causes the arc block 1910 to pop out. At this time, the straight surface of the arc block 1910 will prevent the limiting post 195 from leaving the limiting groove 197, thus making the mold firmly merged together. When separation is required, the arc block 1910 can be retracted into the groove 198 by the pull rod 1911.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
