Description

Technical Field

[0001] This application relates to the technical field of building test detectors, and particularly to a portable hand-held antenna auxiliary tool applied to radar detection. Background Art

[0002] The main functions of tunnel lining are to support and maintain the stability of the tunnel, prevent the surrounding rock from weathering, and relieve the influence of groundwater, etc. The health diagnosis of tunnel lining structure is a key topic in tunnel engineering, which can identify the diseases and defects of the lining structure and prevent safety accidents. Geological radar detection is a relatively advanced detection method with wide application, which can effectively detect the lining thickness and the cavity behind.

[0003] The radar detection support frame is a device used to support the radar antenna for detection operations. At present, the existing radar detection support frames on the market are basically vehicle-mounted support frames, which require a forklift and auxiliary personnel to detect the quality of tunnel lining. They are not applicable to some tunnels with low clearance and small diameter that are not suitable for vehicle-mounted detection.

[0004] For tunnels with small diameter, only the hand-held antenna can be used to enter for detection, and it is quite laborious to hold the hand-held antenna during detection. Content of the Utility Model

[0005] In order to facilitate people to hold the antenna and save physical strength, this application provides a portable hand-held antenna auxiliary tool applied to radar detection.

[0006] This application provides a portable hand-held antenna auxiliary tool applied to radar detection, adopting the following technical solutions:

[0007] A portable hand-held antenna auxiliary tool applied to radar detection includes a mounting seat and a telescopic rod connected to the mounting seat. The mounting seat is equipped with a clamping component for clamping the antenna. An angle adjustment device is installed between the mounting seat and the telescopic rod. It also includes a waist support mechanism, which includes a waistband and a support seat installed on the waistband. The telescopic rod is installed on the support seat.

[0008] By adopting the above technical solutions, after the antenna is installed on the mounting seat, the waistband is worn on the tester. Then, the tester only needs to hold the telescopic rod to hold the antenna on the mounting seat stably. When detecting, the waist strength helps to support the antenna, and the tester's hands can rest alternately, which is relatively labor-saving.

[0009] Optionally, the clamping component includes at least two clamping plates and a driving member for driving the clamping plates to clamp the antenna.

[0010] By adopting the above technical solutions, multiple clamping plates clamp the antenna simultaneously, so that the antenna can be stably installed on the mounting seat.

[0011] Optionally, the driving member is a bidirectional lead screw. The two ends of the bidirectional lead screw are rotatably installed on the mounting seat. There are two clamping plates. Sliders are installed at the lower ends of the two clamping plates. The two sliders are respectively threadedly installed on the positive rotation part and the reverse rotation part of the bidirectional lead screw. One side of the slider is attached to the upper surface of the mounting seat.

[0012] By adopting the above technical solution, rotating the bidirectional lead screw can drive the two clamping plates to approach or move away from each other, facilitating the clamping or loosening of the antenna by the clamping plates.

[0013] Optionally, the angle adjusting device includes an adjusting rod and an adjusting ball fixedly installed at one end of the adjusting rod. The mounting seat is fixedly installed with a mounting hinge seat. The adjusting ball and the hinge seat form a spherical hinge. The hinge seat is provided with a first fixing member for fixing the adjusting ball.

[0014] By adopting the above technical solution, the mounting seat can form a spherical hinge relationship with the mounting seat through the angle adjusting device, enabling the angle of the mounting seat to be adjusted, facilitating better detection by people.

[0015] Optionally, the hinge seat includes a connecting block and a plurality of connecting pieces spacedly installed on the outer peripheral side of the connecting block. An adjusting groove is formed on the connecting block. A receiving space for receiving the adjusting ball is formed between the plurality of connecting pieces and the adjusting groove. External threads are distributed on the outer wall of the connecting piece. The first fixing member is a nut, and the nut is threadedly connected to the plurality of connecting pieces.

[0016] By adopting the above technical solution, when the nut is threadedly connected to the plurality of connecting pieces, the plurality of connecting pieces approach each other and have a clamping effect on the adjusting ball, enabling the adjusting ball to be fixed on the hinge seat.

[0017] Optionally, the other end of the adjusting rod is rotatably installed on the telescopic rod. The rotation center line of the adjusting rod on the telescopic rod is perpendicular to the axis of the telescopic rod. A second fixing member is installed between the telescopic rod and the adjusting rod.

[0018] By adopting the above technical solution, the angular position of the mounting seat can be further adjusted.

[0019] Optionally, one end of the telescopic rod is fixedly connected with a fixing block. Two fixing pieces are installed on the fixing block. A rotating shaft is fixedly installed on one fixing piece. The adjusting rod is rotatably installed on the rotating shaft. The second fixing member is a bolt. The bolt passes through the other fixing piece and is threadedly connected to the rotating shaft. Rotating the bolt makes the two fixing pieces fit on the adjusting rod.

[0020] By adopting the above technical solution, the threaded connection between the bolt and the rotating shaft can control the distance between the two fixing pieces. After the rotation position of the adjusting rod is determined, the two fixing pieces can be driven to fixedly clamp the adjusting rod.

[0021] Optionally, the telescopic rod is rotatably mounted on the support base.

[0022] By adopting the above technical solution, the telescopic rod can not only rotate itself, but also adjust the position of the mounting seat.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By adopting the combined design of the clamping assembly, the angle adjusting device and the waist support mechanism, the antenna can be firmly clamped and the angle and height can be flexibly adjusted, improving the convenience and efficiency of radar detection;

[0025] 2. By adopting the bidirectional lead screw as the driving member, the opening and closing of the clamping plate can be realized by rotating the bidirectional lead screw, so as to conveniently clamp or release the antenna, and the operation is simple and fast.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following is a further detailed description of the present application with reference to the attached Figures 1-4 drawings.

[0032] A portable hand-held antenna auxiliary tool applied to radar detection provided by an embodiment of the present application, such as Figure 1As shown in the figure, it includes a mounting base 1 and a telescopic rod 2 connected to the mounting base 1. A clamping assembly 3 for clamping the antenna is mounted on the mounting base 1, and an angle adjustment device 4 is mounted between the mounting base 1 and the telescopic rod 2. In addition, it also includes a waist support mechanism 5, which includes a waistband 51 and a support base 52 mounted on the waistband 51, and the telescopic rod 2 is mounted on the support base 52.

[0033] The waistband 51 is a waistband 51 with adjustable length to adapt to users with different waist circumferences, improving the versatility and comfort of the auxiliary tool. The waistband 51 is a conventional buckle-type waistband 51.

[0034] Referring to Figure 2 , specifically, the clamping assembly 3 includes at least two clamping plates 31 and a driving member for driving the plurality of clamping plates 31 to clamp the antenna. In this embodiment, the driving member is preferably a bidirectional lead screw 32, and its two ends are rotatably mounted on the mounting base 1. There are two clamping plates 31, and sliders 33 are mounted at the lower ends of the two clamping plates 31. The two sliders 33 are respectively threadedly mounted on the positive rotation part and the reverse rotation part of the bidirectional lead screw 32, so that when the bidirectional lead screw 32 is rotated, the two sliders 33 can move relatively, thereby driving the two clamping plates 31 to open and close. The slider 33 is of a cuboid structure, and the lower surface of the slider 33 fits on the upper surface of the mounting base 1 to ensure the stability of the movement of the slider 33.

[0035] Furthermore, rubber pads 34 are attached to the mutually approaching surfaces of the two clamping plates to protect the radar antenna.

[0036] Referring to Figure 3 , specifically, the angle adjustment device 4 includes an adjustment rod 41 and an adjustment ball 42 fixedly mounted at one end of the adjustment rod 41. The mounting base 1 is fixedly mounted with a mounting hinge seat 6, and the adjustment ball 42 and the hinge seat 6 form a spherical hinge, so that the mounting base 1 can freely adjust the angle within a certain range. The hinge seat 6 is provided with a first fixing member for fixing the adjustment ball 42 to ensure that the position of the mounting base 1 can be fixed after the angle is adjusted.

[0037] Referring to Figure 4 , in this embodiment, the specific structure of the hinge seat 6 includes a connecting block 61 and a plurality of connecting pieces 62 spaced apart and mounted on the outer peripheral side of the connecting block 61. Both the connecting block 61 and the connecting pieces 62 are made of plastic material. An adjustment groove is formed on the connecting block 61, and a receiving space for receiving the adjustment ball 42 is formed between the plurality of connecting pieces 62 and the adjustment groove. External threads are distributed on the outer walls of the plurality of connecting pieces 62, and the first fixing member is a nut 7. The nut 7 is threadedly connected to the plurality of connecting pieces 62, so that the plurality of connecting pieces 62 can be gathered. The gathered plurality of connecting pieces 62 have a fixing effect on the adjustment ball 42. Therefore, the position of the adjustment ball 42 is fixed by tightening the nut 7.

[0038] Referring to Figure 3 and Figure 4, specifically, the other end of the adjusting rod 41 is rotatably mounted on the telescopic rod 2. The rotation center line of the adjusting rod 41 on the telescopic rod 2 is perpendicular to the axis of the telescopic rod 2 to ensure the stability of adjustment. A second fixing member is installed between the telescopic rod 2 and the adjusting rod 41 for fixing the position of the adjusting rod 41 after the angle is adjusted.

[0039] Refer to Figure 3 , more specifically, one end of the telescopic rod 2 is fixedly connected with a fixing block 21, and two fixing pieces 22 are installed on the fixing block 21. A rotating shaft 23 is fixedly installed on one fixing piece 22, and the central axis of the rotating shaft 23 is perpendicular to the central axis of the telescopic rod 2. The adjusting rod 41 is rotatably mounted on the rotating shaft 23. The second fixing member is a bolt 8. The bolt 8 passes through the other fixing piece 22 and is threadedly connected with the rotating shaft 23. By rotating the bolt 8, the two fixing pieces 22 are tightly attached to the adjusting rod 41, thereby fixing the position of the adjusting rod 41.

[0040] In addition, the telescopic rod 2 is rotatably mounted on the support seat 52, so that the telescopic rod 2 can freely rotate on the support seat 52, further increasing the flexibility of the antenna angle adjustment.

[0041] The implementation principle of this embodiment is as follows: First, the user fixes the waist support mechanism 5 on the body through the waist belt 51, and then adjusts the length of the telescopic rod 2 as needed. Next, the user places the antenna in the clamping assembly 3 of the mounting seat 1 and rotates the bidirectional lead screw 32 to clamp the antenna with the clamping plate 31. Subsequently, the user can change the angle of the antenna by adjusting the angle adjusting device 4 to meet different detection requirements. During use, since the entire device is fixed to the waist, the user can free up both hands for other operations, thereby improving work efficiency.

[0042] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
