Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing devices, in particular to a concrete curing device. Background Art

[0002] The gradual hardening and strength increase of concrete is the result of cement hydration, which requires certain temperature and humidity conditions. When the surrounding environment cannot meet these conditions, it is necessary to manually use water spraying and other methods to maintain the concrete. The main purpose of maintenance is to prevent the water in the concrete from evaporating too quickly, resulting in insufficient cement hydration, which will affect the strength and durability of the concrete.

[0003] When curing concrete, a nozzle is usually connected to a water pipe and placed on the concrete surface for water spraying. When using the nozzle, the size of the water spray hole is fixed, and the spraying range of the nozzle cannot be adjusted according to the needs of use during actual use, resulting in low convenience and flexibility in the use of the curing device. Utility Model Content

[0004] The utility model aims to solve the problem that the water spraying aperture size of the nozzle is fixed when the nozzle is used, and the spraying range of the nozzle cannot be adjusted according to the use needs in actual use, resulting in low convenience and flexibility in the use of the curing device. A concrete curing device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a concrete curing device, including a base, the outer surface of the base is fixedly connected to a center tube, one end of the center tube is fixedly connected to a sleeve, the top of the center tube is fixedly connected to a nozzle, the inside of the nozzle is fixedly connected to a conical block, the outer surface of the nozzle is provided with an adjustment device, the adjustment device includes a sleeve, the outer surface of the sleeve is provided with a plurality of output grooves, the outer surface of the sleeve is fixedly connected to a conical ring, the conical ring is located at the bottom end of the output groove, the outer surface edge of the conical ring is higher than the center height, the outer surface of the nozzle is provided with a threaded groove, and the inner wall of the sleeve is threadedly connected to the outer surface of the nozzle provided with the threaded groove.

[0006] The effect achieved by the above components is: by setting the sleeve, when using the curing device to spray and cure the concrete, the water supply pipe is connected to the sleeve at one end of the central pipe. During operation, the sleeve can be rotated to move up and down on the outer surface of the nozzle to adjust the relative positions of the conical ring on the outer surface of the sleeve and the conical block inside the nozzle. When the distance between the conical ring and the conical block is the same as the height of the output groove on the outer surface of the sleeve, the speed of water sprayed through the output groove is relatively slow and the spraying range is small. When the sleeve moves upward on the outer surface of the nozzle, the distance between the conical ring and the conical block is gradually reduced, and the pressure of water sprayed through the output groove gradually increases, and the spraying range increases.

[0007] Preferably, a baffle is fixedly connected to the outer surface of the sleeve, and the baffle is located at the top of the output slot.

[0008] The effect achieved by the above components is that when water flows out through the output groove, the baffle can guide the direction of the water flow, thereby avoiding as much as possible the problem of water spraying vertically upward on the surface of the sleeve, which leads to reduced maintenance effect on the concrete.

[0009] Preferably, a sealing ring is fixedly connected to the bottom end of the sleeve, and the sealing ring is made of rubber material.

[0010] The effect achieved by the above components is: by setting a rubber sealing ring, the contact between the bottom end of the inner wall of the sleeve and the outer surface of the nozzle can be further sealed, thereby avoiding as much as possible the problem of water seeping out through the bottom end of the connection between the sleeve and the nozzle, resulting in reduced water pressure and waste of water resources.

[0011] Preferably, a plurality of convex strips are fixedly connected to the top end of the sleeve, and the convex strips are distributed in a circular shape on the outer surface of the sleeve.

[0012] The effect achieved by the above components is that when controlling the sleeve to rotate, the hand can be pressed against the convex strip at the top of the sleeve to increase the friction between the hand and the outer surface of the sleeve, making it more convenient to rotate the sleeve and less likely to slip.

[0013] Preferably, an elastic rope is fixedly connected to the top end of the sleeve, and an end of the elastic rope away from the sleeve is fixedly connected to one side of the nozzle.

[0014] The effect achieved by the above components is that when the sleeve is removed during maintenance and inspection of the nozzle, the sleeve can be temporarily fixed to the outside of the base through an elastic rope, making it easy to take the sleeve for installation and use.

[0015] Preferably, a clamping device is provided on one side of the sleeve, and the clamping device includes two screws, the outer surfaces of the two screws have threads in opposite directions, one end of the screw is fixedly connected to an L-shaped rod, one side of the L-shaped rod slides on one side of the sleeve, one end of the L-shaped rod is fixedly connected to a bent rod, one side of the sleeve is rotatably connected to a threaded barrel, and the upper and lower sides of the inner wall of the threaded barrel are respectively threadedly connected to the outer surfaces of the two screws.

[0016] The effect achieved by the above components is: by setting the bent rod, after the water pipe is connected to the casing, the threaded barrel can be pushed to rotate so that the two screws move in the same direction on the inner wall of the threaded barrel, driving the L-shaped rod to slide on one side of the casing, and the bent rods at one end of the two L-shaped rods are respectively clamped on the upper and lower sides of the water pipe, thereby further strengthening the connection between the water pipe and the casing and preventing the water pipe from falling off as much as possible.

[0017] Preferably, a plurality of protrusions are fixedly connected to one side of the bending rod, and the protrusions are rubber blocks made of rubber material.

[0018] The effect achieved by the above components is that when the side of the bent rod provided with the rubber bump is pressed against the outer surface of the water pipe, the contact with the outer surface of the water pipe is closer and less likely to slide, and the connection and fixation of the water pipe and the sleeve are more stable.

[0019] Preferably, one side of the sleeve is fixedly connected to a positioning rod, the L-shaped rod is located between the positioning rod and the sleeve, and one side of the L-shaped rod slides on one side of the positioning rod.

[0020] The effect achieved by the above components is: when the threaded barrel is rotated to control the two screws to drive the L-shaped rod to move up and down, the L-shaped rod will move between the positioning rod and the sleeve. The positioning rod can further limit the angle between the L-shaped rod and the sleeve, thereby avoiding the angle of the L-shaped rod from being deflected as much as possible.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by providing an adjustment device, the sleeve can be rotated to control the sleeve to move up and down on the outer surface of the nozzle provided with a threaded groove, and the distance between the conical ring and the conical block can be adjusted to change the size of the output groove, so as to control the spraying height and spraying range of the water sprayed at the output groove, thereby improving the convenience and practicality of using the maintenance device.
