Description

Technical Field

[0001] This utility model relates to the field of concrete sample curing technology, specifically a constant temperature water curing box for concrete sample curing. Background Technology

[0002] A standard curing system for concrete specimens is a specialized device for curing concrete specimens. It provides a specific temperature and humidity environment to ensure that the concrete specimens achieve optimal strength growth during the curing process.

[0003] In the production and construction of concrete, concrete strength is a very important indicator. The strength growth of concrete is closely related to curing conditions, among which temperature and humidity are two of the most critical factors. A large amount of experimental data shows that under suitable temperature and humidity conditions, the strength growth rate of concrete will be significantly accelerated, thereby improving the quality and performance of concrete.

[0004] Therefore, in order to ensure that concrete specimens achieve the best strength growth during the curing process, a standard curing system for concrete specimens is required to provide a specific temperature and humidity environment. Such equipment and facilities usually employ advanced temperature and humidity control systems that can precisely control the temperature and humidity in the curing chamber, thereby ensuring that the concrete specimens are always in a suitable environment during the curing process.

[0005] Existing constant temperature water curing chambers for concrete sample curing are generally designed to address the problem that when there are many samples in the constant temperature chamber, the increased water mist can easily cause the glass lens to become blurry, making it difficult for staff to observe and record the samples through the glass lens, thus affecting test recording. For example, the constant temperature water curing chamber for concrete sample curing disclosed in the authorized Chinese patent CN218462523U can facilitate the clear observation and recording of samples in the constant temperature chamber by using a combination of structures such as the curing chamber body, constant temperature chamber, wiping assembly, wiping rod, drive rope, first rod body, first perforation, second rod body, second perforation, snap-fit ​​protrusion, wiping sponge, embedded groove, box cover frame, glass plate, snap-fit ​​slide, hinge cylinder, connecting rope, through hole, knob, hinge part, grip part, rotation mark, grip groove, limit nut, elastic rubber strip, and guide rod.

[0006] However, the constant temperature water curing chambers used for concrete sample curing in the above-cited documents have some significant drawbacks in use. First, existing constant temperature water curing chambers for concrete testing are difficult to accurately track the curing start time and remaining curing time of different samples. This is because the equipment usually uses a simple timing device, which cannot accurately record the curing start time and remaining curing time of each sample. This results in two problems: first, missing key curing points, thus affecting the performance and quality of the concrete; and second, excessively long curing times, wasting time and resources.

[0007] Secondly, the existing constant temperature water curing chamber for concrete testing does not have a movable partition structure, making it impossible to flexibly adjust the spatial layout between specimens. The spatial layout between specimens is fixed and cannot be adjusted according to actual needs. This fixed spatial layout may lead to several problems: firstly, mutual interference between specimens affects the performance and quality of concrete; secondly, it fails to make full use of the curing chamber space, reducing the efficiency of the equipment.

[0008] In summary, existing constant temperature water curing chambers for concrete testing have several drawbacks, including difficulty in accurately tracking the curing start time and remaining curing time of different samples, lack of movable partitions, and inability to flexibly adjust the spatial layout between samples. These shortcomings seriously affect their performance and reliability, and therefore require improvement and optimization. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a constant temperature water curing chamber for concrete sample curing, which has the advantages of flexible adjustment of the sample chamber spatial layout and accurate recording of curing time. It solves the problems of existing constant temperature water curing chambers that cannot flexibly adjust the sample chamber spatial layout and are difficult to accurately track the start time and remaining curing time of different samples.

[0010] In summary, this utility model provides the following technical solution: a constant temperature water curing chamber for concrete sample curing, comprising a constant temperature curing chamber, a pull-out box, and a timer. The inner wall of the constant temperature curing chamber is equipped with a movable partition structure that is evenly distributed. A pull-out box is connected between the opposite sides of two corresponding movable partition structures on the left and right sides. The timer is fixedly installed on the inner wall of the constant temperature curing chamber, and there are multiple timers arranged at equal intervals.

[0011] The movable partition structure includes a fixed recess fixedly installed on the inner wall of the constant temperature curing chamber and a locking block fixedly connected to one side of the pull-out box. A control box and a drive component installed in the control box are fixedly connected to one side of the fixed recess.

[0012] The fixed recess has a movable hole through which the drive component passes;

[0013] The movable partition structure also includes a support block that is bolted to the inner wall of the control box and slidably connected to the drive component. A hollow movable block that is bolted to the inner wall of the control box and slidably connected to the drive component is also mounted on the drive component. An auxiliary movable component is mounted on the drive component.

[0014] Furthermore, the outer side of the card block slides against the inner side of the fixing recess.

[0015] The above technical solution is adopted so that when the card block and the fixed recess are connected to each other, they can provide reliable support for the pull-out box, ensuring that it will not easily shake or deform when bearing weight or subjected to external force. At the same time, through this close-fitting sliding connection, the pull-out box can be smoothly pulled out or pushed back while maintaining stability. The pull-out box can remain horizontal during movement without tilting or shaking, making it convenient for users to pick up and put in concrete samples.

[0016] Furthermore, the drive assembly includes a threaded rod, a rotating handle, a threaded sleeve, and a plug; one end of the threaded rod is fixedly connected to one side of the rotating handle, and the other end passes through the control box and extends to the moving hole; the inner side of the threaded sleeve is threadedly connected to the outer side of the threaded rod; and one end of the plug is fixedly connected to one end of the threaded sleeve.

[0017] The purpose of adopting the above technical solution is to drive the threaded rod to rotate when the handle is turned, so that the threaded sleeve can move on the outside of the threaded rod under the thrust of the inner thread rotation, and push the insert block to move.

[0018] Furthermore, the outer side of the threaded sleeve slides between the inner side of the support block and the hollow moving block.

[0019] The purpose of adopting the above technical solution is to further improve the stability of the threaded sleeve movement.

[0020] Furthermore, the projection of the insert block in the first direction is a circle with a diameter of L, the first direction is parallel to the axial direction of the moving hole, and the diameter of the moving hole is D, where D=L.

[0021] The purpose of adopting the above technical solution is to enable the insert to slide stably within the moving hole.

[0022] Furthermore, a slot is provided on one side of the card block for the insertion block to fit and be inserted.

[0023] The above technical solution is adopted so that its size and shape are precisely designed to accommodate the insert block and fit it tightly. This design has an important purpose: to effectively limit the movement range of the card block through the cooperation between the slot and the insert block. When the insert block is fully inserted into the slot, the tight fit between them forms a firm connection, preventing the card block from moving freely in the horizontal direction. This limiting effect is crucial to prevent the pull-out box from accidentally falling out of the constant temperature curing chamber.

[0024] Furthermore, the auxiliary moving component includes a connecting block and a sliding rod; one side of the connecting block is fixedly connected to the outside of the threaded sleeve, and there are two connecting blocks distributed in a mirror symmetrical manner; both ends of the sliding rod are fixedly connected to the inner side wall of the control box and one side of the support block, respectively; the outer side of the sliding rod is slidably connected to and slides in contact with the inner side of the connecting block.

[0025] The purpose of adopting the above technical solution is to further improve the stability of the threaded sleeve movement and limit the movement distance.

[0026] Compared with the prior art, this utility model provides a constant temperature water curing chamber for curing concrete samples, which has the following beneficial effects:

[0027] This constant temperature water curing chamber for concrete specimen curing utilizes a movable partition structure, pull-out boxes, and timers to provide a flexible spatial layout that can be adjusted according to the curing needs of different specimens. This maximizes the use of the curing chamber space, improves equipment efficiency, and ensures that each partition area is equipped with an independent timer to accurately record the start and remaining curing time of each specimen. This prevents missing critical curing points, reduces quality problems caused by improper curing, and ensures the performance and quality of the concrete. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1 to 4 This utility model provides a technical solution: a constant temperature water curing box for curing concrete samples, including a constant temperature curing box 1, a pull-out box 3 and a timer 4. The inner side wall of the constant temperature curing box 1 is equipped with a movable partition structure 200 that is evenly distributed. The pull-out box 3 is connected between the opposite sides of two corresponding movable partition structures 200 on the left and right sides. The timer 4 is fixedly installed on the inner side wall of the constant temperature curing box 1 and there are multiple timers 4 arranged at equal intervals.

[0036] By using the movable partition structure 200, pull-out box 3, and timer 4 on the constant temperature curing chamber 1 in coordination, a movable partition structure can be provided. The spatial layout between the specimens can be flexibly adjusted according to the curing requirements of different specimens, making full use of the curing chamber space and improving equipment utilization efficiency. In addition, each partition area is equipped with an independent timer, which can accurately record the curing start time and remaining curing time of each specimen, avoid missing key curing nodes, reduce quality problems caused by improper curing, and ensure concrete performance and quality.

[0037] In this embodiment, the movable partition structure 200 is a structure that allows for flexible adjustment of the spatial layout between specimens according to the curing requirements of different specimens.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the movable partition structure 200 includes a fixed recess 201 fixedly installed on the inner wall of the constant temperature curing chamber 1 and a locking block 202 fixedly connected to one side of the pull-out box 3. A control box 203 and a drive component installed in the control box 203 are fixedly connected to one side of the fixed recess 201.

[0039] The fixed recess 201 has a movable hole 205 for the drive component to pass through;

[0040] The movable partition structure 200 also includes a support block 207 that is bolted to the inner wall of the control box 203 and slidably connected to the drive component. A hollow moving block 208 that is bolted to the inner wall of the control box 203 and slidably connected to the drive component is installed thereon. An auxiliary moving component is installed on the drive component.

[0041] It should be noted that the outer side of the locking block 202 slides against the inner side of the fixing recess 201 so that when the locking block 202 and the fixing recess 201 are connected, they can provide reliable support for the pull-out box 3, ensuring that it will not easily shake or deform when bearing weight or subjected to external forces. At the same time, through this close sliding connection, the pull-out box 3 can be smoothly pulled out or pushed back while maintaining stability. The pull-out box 3 can remain horizontal during movement without tilting or shaking, making it convenient for users to pick up and put down concrete samples.

[0042] Understandably, the drive assembly includes a threaded rod 2041, a handle 2042, a threaded sleeve 2043, and a plug 2044. One end of the threaded rod 2041 is fixedly connected to one side of the handle 2042, and the other end passes through the control box 203 and extends to the moving hole 205. The inner side of the threaded sleeve 2043 is threadedly connected to the outer side of the threaded rod 2041. One end of the plug 2044 is fixedly connected to one end of the threaded sleeve 2043 so that when the handle 2042 is rotated, the threaded rod 2041 can be rotated, thereby causing the threaded sleeve 2043 to move on the outer side of the threaded rod 2041 under the thrust of the inner thread rotation, and pushing the plug 2044 to move.

[0043] In addition, the outer side of the threaded sleeve 2043 slides between the support block 207 and the inner side of the hollow moving block 208 in order to further improve the stability of the movement of the threaded sleeve 2043.

[0044] In this embodiment, the projection of the insert 2044 in the first direction is a circle with a diameter of L. The first direction is parallel to the axial direction of the moving hole 205. The diameter of the moving hole 205 is D, where D=L, so that the insert 2044 can slide stably within the moving hole 205.

[0045] It should also be noted that a slot 206 is provided on one side of the card block 202 for the insertion block 2044 to fit snugly into. This slot 206 is precisely designed in size and shape to accommodate the insertion block 2044 tightly. This design serves an important purpose: through the interaction between the slot 206 and the insertion block 2044, the movement range of the card block 202 is effectively limited. When the insertion block 2044 is fully inserted into the slot 206, their tight fit forms a secure connection, preventing the card block 202 from moving freely in the horizontal direction. This limiting effect prevents the pull-out box 3 from accidentally falling out of the constant temperature curing chamber 1. The detachment is crucial. In actual use, when the pull-out box 3 is fully inserted into the constant temperature curing chamber 1, the locking block 202 and the fixing recess 201 are connected to each other, providing stable support. At this time, the insert block 2044 is inserted into the slot 206, further enhancing the stability of this connection. Even under external impact or vibration, the pull-out box 3 can remain firmly in place and will not easily fall off. In addition, the cooperation between the slot 206 and the insert block 2044 also plays a positioning role, ensuring that the pull-out box 3 can be accurately aligned and installed when inserted into the constant temperature curing chamber 1, avoiding instability or other problems caused by positional deviation.

[0046] It should be further explained that the auxiliary moving component includes a connecting block 2091 and a sliding rod 2092; one side of the connecting block 2091 is fixedly connected to the outside of the threaded sleeve 2043, and there are two connecting blocks 2091 distributed in a mirror symmetrical manner. The two ends of the sliding rod 2092 are respectively fixedly connected to the inner side wall of the control box 203 and one side of the support block 207. The outer side of the sliding rod 2092 and the inner side of the connecting block 2091 are slidably connected and slide in contact, which is to further improve the stability of the movement of the threaded sleeve 2043 and limit the movement distance.

[0047] The working principle of the above embodiments is as follows:

[0048] When the spatial layout needs to be adjusted, turn the handle 2042 counterclockwise to rotate the threaded rod 2041. The threaded sleeve 2043 rotates counterclockwise outside the threaded rod 2041, while simultaneously sliding between the support block 207 and the hollow moving block 208. This causes the insert block 2044 to move away from the locking block 202. When the insert block 2044 is completely disengaged from the slot 206, the locking block 202 is no longer restricted and can slide freely inside the fixed recess 201, pushing the pull-out box 3. Under the connection of the locking block 202 and the fixed recess 201, it moves along the inner wall of the constant temperature curing chamber 1, thereby adjusting the spatial layout between the pull-out boxes 3. When the desired position is reached, turn the handle 2042 clockwise to rotate the threaded rod 2041. When the threaded rod 2041 rotates, the threaded sleeve 2043 rotates clockwise outside the threaded rod 2041, and simultaneously slides between the support block 207 and the hollow moving block 208, thereby driving the insert block 2044 to move closer to the locking block 202. When the insert block 2044 is fully inserted into the slot 206, the locking block 202 is restricted within the fixed recess 201 and cannot move, thus fixing the position of the pull-out box 3. Each pull-out box 3 is equipped with an independent timer 4, which can accurately record the curing start time and remaining curing time of each sample. Users can understand the curing status of the sample in a timely manner according to the display of the timer 4, avoid missing key curing nodes, reduce quality problems caused by improper curing, and ensure the performance and quality of concrete.

[0049] Compared with existing technologies, this constant temperature water curing chamber for concrete specimen curing provides a movable partition structure through the coordinated use of the movable partition structure 200, pull-out box 3, and timer 4 on the constant temperature curing chamber 1. This allows for flexible adjustment of the spatial layout between specimens according to the curing needs of different specimens, making full use of the curing chamber space and improving equipment efficiency. Furthermore, each partition area is equipped with an independent timer, which can accurately record the curing start time and remaining curing time of each specimen, avoiding missing key curing nodes, reducing quality problems caused by improper curing, and ensuring concrete performance and quality. This solves the problems of existing constant temperature water curing chambers, such as the inability to flexibly adjust the spatial layout between specimens and the difficulty in accurately tracking the curing start time and remaining curing time of different specimens.

[0050] All electrical components mentioned in this document are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control. Furthermore, the existing publicly available power connection technology and power supply are common knowledge in this field, so this application will not elaborate further.
