Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a corrosion-resistant detection device for building materials that is convenient for opening and closing a maintenance door. Background Technique

[0002] Building materials are various materials used in construction projects. There is a wide variety of building materials, including metal materials and non-metal materials. For metal materials, steel is one of the commonly used building materials. Steel is vulnerable to corrosion effects from the external environment such as air. To ensure building safety, it is necessary to test the corrosion resistance of steel. To test the corrosion resistance of steel, a corrosion-resistant detection device is required to detect the steel.

[0003] The corrosion-resistant detection device for building materials usually has a box structure for the cavity. The building materials to be detected (such as steel) are placed inside the cavity of the corrosion-resistant detection device for detection. To enable detection, various detection components need to be installed inside the corrosion-resistant detection device. When it is necessary to detect and repair the internal monitoring components (such as replacing components), the operator needs to be able to access the corrosion-resistant detection device for operation. This requires a maintenance door to be installed on the corrosion-resistant detection device.

[0004] In existing corrosion-resistant detection devices, the maintenance door is usually installed on the corrosion-resistant detection device by means of screws passing through and screwing together, or connected to the corrosion-resistant detection device by other connectors (such as screws, bolts, etc.). When it is necessary to open the maintenance door to repair the detection components inside the corrosion-resistant detection device, it can only be achieved by disassembling the maintenance door. Disassembling the maintenance door requires the use of special tools to remove connectors such as screws, screws, and bolts. The operation is complex, and the maintenance door cannot be quickly opened, resulting in low maintenance efficiency. Therefore, a corrosion-resistant detection device that is convenient to operate and can quickly open and close the maintenance door is needed. Content of the Utility Model

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation plans:

[0026] like Figures 1 - 4As shown in the figure, a corrosion-resistant detection device for building materials that facilitates the opening and closing of the inspection door 4 includes a detection box body 1, an inspection door 4, and an inspection groove 3 dug in the detection box body 1. A through hole communicating with the inside of the inspection box body is provided at the bottom of the inspection groove 3, and the inspection door 4 is installed in the inspection groove 3.

[0027] In an alternative embodiment, a top cover 2 is also movably installed at the top end of the detection box body 1. A handle 600 is installed on the top cover 2. The top cover 2 can move relative to the detection box body 1, including being able to flip or lift relative to the detection box body 1 to open the top cover 2 from the detection box body 1, facilitating the placement of the building materials to be detected into the detection box body 1.

[0028] It also includes an operation component 5, a connection component, a rotation component, and a limit component. The inspection door 4 is movably installed in the inspection groove 3 through the connection component. The rotation component is installed on the inspection door 4, and the limit component is installed on the inspection door 4. The limit component is used to limit and release the limit of the inspection door 4 in the inspection groove 3, so as to fixedly connect the inspection door 4 to the detection box body 1 and allow the inspection door 4 to be opened from the detection box body 1. The operation component 5 is installed on the inspection door 4 and connected to the limit component. The operation component 5 is used to drive the limit component to move to the corresponding position, so that the limit component reaches the position where it limits and releases the limit of the inspection door 4. The rotation component is installed in the inspection door 4 and the inspection groove 3. The rotation component is used to screw out the inspection door 4 from the inspection groove 3 after the limit is released, thereby opening the inspection door 4.

[0029] The limit component includes a limit groove 300, an internal groove 301, a telescopic spring 303, a sleeve rod (not shown in the figure), and a limit block 302. The limit groove 300 is opened in the inspection groove 3. The internal groove 301 is opened in the inspection door 4 and is arranged along the thickness direction of the inspection door 4. The internal groove 301 and the limit groove 300 correspond to each other and are located directly below the limit groove 300. The sleeve rod is vertically and fixedly installed in the internal groove 301. The telescopic spring 303 is sleeved on the sleeve rod. The two ends of the telescopic spring 303 respectively abut against the lower surface of the limit block 302 and the bottom wall of the limit groove 300. At least a part of one end of the sleeve rod extends into the limit block 302. The limit block 302 can move along the axial direction of the sleeve rod and can at least reach the first position and the second position. The limit block 302 drives the telescopic spring 303 to expand and contract synchronously during the process of moving along the axial direction of the sleeve rod.

[0030] Among them, the first position: the limit block 302 completely exits from the limit groove 300, and the limit block 302 partially or completely retracts into the internal groove 301, and the telescopic spring 303 is in a compressed state.

[0031] Second position: The limiting block 302 at least partially extends into the limiting groove 300, and the telescopic spring 303 is in a natural state or a compressed state. Here, the natural state means that under the action of the sleeve rod supporting the limiting block 302, the acting force of the self-gravity of the limiting block 302 on the telescopic spring 303 is zero or insufficient to cause tensile and compressive deformation of the telescopic spring 303, and the telescopic spring 303 is still regarded as a state without being subjected to external forces and without tensile and compressive deformation.

[0032] In an alternative embodiment, a guiding assembly is further included. The guiding assembly is connected to the limiting block 302 and is used to guide the limiting block 302 during the axial movement along the sleeve rod, so that the limiting block 302 can maintain a vertical linear movement.

[0033] The guiding assembly includes a guiding block 401 and a guiding groove 400. The guiding block 401 can be a rectangular block. The guiding block 401 is convexly and fixedly installed on one side of the limiting block 302 and is close to the lower edge of the limiting block 302. The lower surface of the guiding block 401 is flush with the lower surface of the limiting block 302. The guiding groove 400 is opened on the inner side wall of one side of the built-in groove 301, and the opening of the guiding groove 400 faces the limiting block 302. At least a part of the end of the guiding block 401 away from the limiting block 302 extends into the guiding groove 400.

[0034] During the vertical up-and-down movement transition of the limiting block 302, the guiding block 401 slides in the guiding groove 400, thereby playing a guiding role in the movement of the limiting block 302.

[0035] The operating assembly 5 includes an operating rod 501 and a through groove 500. The through groove 500 runs through and is opened on the inner wall of the built-in groove 301 and is located on the inner wall of the other side of the built-in groove 301 away from the guiding groove 400. The operating rod 501 is T-shaped. One end of the operating rod 501 passing through the through groove 500 is connected to the limiting block 302. The operating rod 501 can move along the axial direction of the through groove 500, so that the limiting block 302 can be driven to move up and down by operating the operating rod 501.

[0036] Wherein, the operating rod 501 is fixedly or detachably connected to the end face of the limiting block 302 facing away from the guiding block 401. Of course, the operating rod 501 can also extend into the limiting block 302 and be fixedly or detachably connected to the limiting block 302.

[0037] The connecting assembly includes a connecting groove 100 and a connecting block 101. The connecting groove 100 runs through and is opened on one side of the access door 4. The connecting block 101 is fixedly installed on one side of the inner wall of the maintenance groove 3. The connecting block 101 is snap-fitted to the connecting groove 100, so that the access door 4 is connected to the maintenance groove 3.

[0038] The rotating assembly includes a rotating groove 200 and a rotating block 201. The rotating groove 200 is formed in the connecting block 101, and the rotating block 201 is fixed to the inner wall of the connecting groove 100. The rotating block 201 is rotatably connected to the rotating groove 200. When the rotating block 201 rotates counterclockwise within the rotating groove 200, the inspection door 4 is rotated out of the inspection recess 3, causing the inspection door 4 to disengage from the inspection recess 3. When the rotating block 201 rotates clockwise within the rotating groove 200, the inspection door 4 is rotated into the inspection recess 3, causing the inspection door 4 to be located within the inspection recess 3.

[0039] During actual use, by manually or using an external tool / device to operate the operating rod 501, the operating rod 501 moves downward along the through groove 500, thereby driving the limiting block 302 to move downward by the operating rod 501. The limiting block 302 completely disengages from the limiting groove 300, and at this time, the limiting block 302 does not obstruct the inspection door 4. Then, pull the operating rod 501 outward. Figure 4 For example, when the operating rod 501 moves from left to right, it is pulling the operating rod 501 outward. This drives the inspection door 4 to move away from the inspection recess 3. Figure 1 For example, the inspection door 4 moves outward in a direction perpendicular to the screen, that is, moves outside the inspection recess 3. During the movement of the inspection door 4, it drives the connecting groove 100 to rotate on the surface of the connecting block 101 with the rotating block 201 as the center, and simultaneously drives the rotating block 201 to rotate inside the rotating groove 200, so that the free end of the inspection door 4 rotates out of the inside of the inspection recess 3, opening the inspection door 4, and thus the inside of the detection box 1 can be operated and inspected. When it is necessary to close the inspection door 4, only the reverse operation is required.

[0040] Among them, if it is necessary to place the building materials to be detected, the top cover 2 can be lifted by the handle 600 to achieve this.

[0041] The utility model can realize the opening and closing of the inspection door 4 through rotational operation, without the need to open the inspection door 4 by disassembling the connecting parts with the aid of tools. The operation is simple, the operation efficiency of opening and closing the inspection door 4 is high, and the inspection efficiency is even higher. In addition, the structure is simple, the manufacturing cost is low, and it is easy to maintain.

[0042] The embodiments disclosed in this specification are only an illustration of the unilateral features of the utility model. The protection scope of the utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
