Description

Technical Field

[0001] This utility model relates to the field of recycled concrete curing technology, and in particular to a concrete curing box adapted to different test blocks. Background Technology

[0002] In the development of construction engineering, people have gradually realized that the curing conditions of concrete test blocks have a significant impact on the test results of their strength and other properties. To accurately evaluate the performance of concrete in actual use, it is necessary to simulate specific temperature and humidity environments for curing the test blocks. In the early days, there were no dedicated concrete test block curing boxes in construction. Test blocks were usually cured in the natural environment of the construction site or placed in makeshift locations where temperature and humidity conditions were difficult to control precisely. This resulted in unstable curing conditions and low accuracy and reliability of the test results. Announcement No. CN213875174U discloses a concrete test block curing box, belonging to the field of recycled concrete curing technology. It includes a box body, several support rollers, and several placement plates. One end of each vertical support roller is fixedly connected to the top or bottom of the box body, and the other end of the support roller has a gap between it and the bottom or top of the box body. Several collars are fixedly connected to the placement plates, and these collars are detachably connected to the support rollers. The placement plates are equipped with locking components, which are detachably connected to the corresponding support rollers. Although the equipment can adapt the curing box to test blocks of different shapes, it is extremely inconvenient to operate and has low work efficiency due to the manual disassembly and assembly method. Furthermore, manual disassembly can disrupt the temperature and humidity inside the curing box, which is detrimental to the curing of concrete. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a concrete curing box adapted to different test blocks, including a casing, the casing including a storage device and a support device, a self-locking motor fixedly installed inside the casing, a gear fixedly installed at the output end of the self-locking motor, a rack meshing on the surface of the gear, a support frame slidably connected to the surface of the rack, a support platform fixedly installed on the side of the rack, a support rod fixedly installed on the surface of the support platform, a support plate fixedly installed on the surface of the support rod, a sliding ring fixedly installed on one side of the support plate, a fixing hole A opened on the inner surface of the support plate, the storage device including a storage plate, a spring A fixedly installed inside the storage plate, a plug fixedly installed at one end of the spring A, a top plate fixedly installed inside the plug, a button A fixedly installed on the surface of the top plate, a spring B fixedly installed inside the button A, and a button B fixedly installed at one end of the spring B.

[0005] Preferably, the racks are arranged in two symmetrical sets, each meshing with a gear; the support frames are arranged in two symmetrical sets, each slidingly connected to the surface of the racks; and the support platforms are arranged in two symmetrical sets, each fixedly connected to the side of the racks. Here, the two sets of racks can move up and down alternately when the gears rotate, achieving asymmetrical adjustment.

[0006] Preferably, the number of support rods is two sets symmetrically distributed and both are fixedly connected to the surface of the support platform, and the number of support plates is two sets interspersed and both are fixedly connected to the surface of the support rods. Here, the support rods on both sides can control different support plates.

[0007] Preferably, the bottom end of the support frame is fixedly connected to the inner surface of the chassis, and the surface of one side of the support rod is slidably connected to the inner side of the sliding ring. This ensures that the support rod does not move or pull on the other side when it is raised or lowered.

[0008] Preferably, the support device includes a guide rail, with a pulley slidably connected inside the guide rail. A bracket is fixedly installed on one side of the pulley, and a fixing hole B is formed on the surface of the bracket. A support wheel is fixedly installed on the surface of the guide rail. Here, by setting the bracket, the placement frame can be pulled out simply when the test block needs to be placed, which is convenient for placement.

[0009] Preferably, the lower surface of the guide rail is fixedly connected to the inner surface of the support plate, and the inner side of the bracket is slidably connected to the surface of the support wheel. Here, the support plate is fixed to prevent slippage during use, and the support wheel assists the bracket in sliding.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model, by setting a self-locking motor, gears, racks, support frames, support platforms, support rods, support plates, and sliding rings, eliminates the need for manual disassembly and assembly of support frames to adjust the spacing when different sized test blocks need to be placed. Simply starting the motor drives the support rod to achieve adjustment, effectively solving the problem of low manual efficiency. Furthermore, the non-uniform spacing adjustment allows test blocks to be placed on different shelves according to their size, maximizing space utilization. When the spacing is too large or too small, the shelf can be disassembled and adjusted to accommodate different test blocks.

[0012] 2. In this utility model, by setting up a shelf, spring, plug, button, top plate, spring, bracket, pulley and guide rail, when it is necessary to place the test block, there is no need to put your hand into the equipment. Just press the button and pull out the shelf, which will bring out the bracket. With the support of the bracket, the test block can be placed without putting your hand into the equipment, making the placement simpler and more convenient. Attached Figure Description

The casing 1 contains a storage device 2 and a support device 3. A self-locking motor 4 is fixedly installed inside the casing 1, allowing it to maintain support even when not in use. A gear 5 is fixedly installed at the output end of the self-locking motor 4. A rack 6 meshes with the surface of the gear 5. A support frame 7 is slidably connected to the surface of the rack 6, providing stable sliding support for the rack 6. A support platform 8 is fixedly installed on the side of the rack 6, allowing the rack 6 to move freely. The device is capable of moving a support platform 8. A support rod 9 is fixedly installed on the surface of the support platform 8, so that the support platform 8 can move the support rod 9 when it moves. A support plate 10 is fixedly installed on the surface of the support rod 9. A sliding ring 11 is fixedly installed on one side of the support plate 10, so that the support plate 10 can move on the corresponding support rod 9 when it moves. A fixing hole A12 is opened on the inner surface of the support plate 10, so that the plug 15 can be inserted for fixing. The storage device 2 includes a storage plate 13. A spring A14 is fixedly installed inside the storage plate 13. One end of the device is fixedly fitted with a plug 15, and a top plate 16 is fixedly fitted inside the plug 15, allowing the device to compress the spring A14 by pressing the top plate 16. A button A17 is fixedly fitted on the surface of the top plate 16, allowing for easy pressing of the top plate 16. A spring B18 is fixedly fitted inside the button A17, allowing it to automatically rebound after being pressed. A button B19 is fixedly fitted to one end of the spring B18. The number of racks 6 is two sets symmetrically distributed and both mesh with the gears 5. The number of support frames 7 is two sets symmetrically distributed and both mesh with the racks. The surface of the rack 6 is slidably connected. The number of support platforms 8 is two sets symmetrically distributed and fixedly connected to the side of the rack 6. The number of support rods 9 is two sets symmetrically distributed and fixedly connected to the surface of the support platform 8. The number of support plates 10 is two sets interlaced and fixedly connected to the surface of the support rods 9. The bottom end of the support frame 7 is fixedly connected to the inner surface of the chassis 1 so that the support frame 7 can be fixed. The surface of one side of the support rod 9 is slidably connected to the inner side of the sliding ring 11 so that the lifting and lowering of the support rod 9 will not affect the lifting and lowering of the other side of the support rod 9.

[0026] Example 2

[0027] Please see Figure 6-7The support device 3 includes a guide rail 20, with a pulley 21 slidably connected inside the guide rail 20 to prevent the pulley 21 from shifting when moving. A bracket 22 is fixedly installed on one side of the pulley 21 to make the bracket 22 move more smoothly. A fixing hole B23 is opened on the surface of the bracket 22 to allow the plug 15 to be inserted and fixed. A support wheel 24 is fixedly installed on the surface of the guide rail 20 to assist the movement of the guide rail 20. The lower surface of the guide rail 20 is fixedly connected to the inner surface of the support plate 10. The inner side of the bracket 22 is slidably connected to the surface of the support wheel 24 to make the bracket 22 slide more smoothly.

[0028] Working Principle: When the curing box needs to be used to accommodate different test blocks, the self-locking motor 4 inside the housing 1 is started. The operation of the self-locking motor 4 drives the gear 5 at the output end to rotate. Since both gear 5 and rack 6 are meshed, the rotation of gear 5 causes rack 6 to slide on the surface of support frame 7. When rack 6 slides, the support platform 8 on its side will move accordingly. The support platform 8 drives the support rod 9 and support plate 10 on its surface to move, and the sliding ring 11 on one side of support plate 10 will also move synchronously. Similarly, when the other set of racks 6 slides, the support platform 8, support rod 9, support plate 10 and sliding ring 11 will also move accordingly. By adjusting the position of the two sets of racks 6, the spacing of the support plates 10 on the support rod 9 can be changed, thereby adjusting the spacing between the placement plates 13 inside the different support plates 10. Since the two support plates 10 are installed crosswise and the two sets of racks 6 move in opposite directions, non-equidistant spacing adjustment is achieved after movement to adapt to the placement requirements of test blocks of different sizes, while maximizing space utilization. When it is necessary to remove the shelf 13, press buttons A17 and B19 simultaneously. Springs A14 and B18 will be compressed by the pressure of buttons A17 and B19, and the plug 15 will be pulled out of the socket, thus removing the shelf 13. When it is necessary to install the shelf 13, simply push the shelf 13 into the support plate 10. After it is fully pushed in, the plug 15 will lock itself under the force of spring A14. When it is necessary to place a test block, press button A17 to pull the shelf 13 outward. Since button B19 is not pressed, its plug 15 is not fully retracted. When pulling out the shelf 13, the bracket 22 can be pulled out at the same time to support the shelf 13, so that it can be placed externally.

[0029] Finally, the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the protection scope of this utility model.
