Description

Technical Field

[0001] The embodiments of the present application relate to the field of measuring instruments, and in particular to a measuring device, a fixture and a measuring equipment. Background Art

[0002] The installation posture of the base station antenna has a huge impact on the surrounding signal coverage. After the antenna is installed, the installation posture needs to be measured, and the measurement results are used to determine whether the antenna installation needs to be adjusted and optimized. Therefore, the accuracy of the measurement results will directly affect the use of the antenna. Summary of the invention

[0003] The embodiments of the present application provide a measuring device, a fixture and a measuring equipment, which solve the problem of inaccurate measurement results of antennas.

[0004] In order to achieve the above-mentioned purpose, this application adopts the following technical solution.

[0005] In the first aspect, an embodiment of the present application provides a measuring device. The measuring device includes a host, a support assembly and a receiving assembly. The support assembly includes a first connecting rod and a cable connected to each other. One end of the first connecting rod is connected to the host, and one end of the cable is electrically connected to the host. The receiving assembly includes a receiver, a signal processor, a second connecting rod and a coaxial line. The coaxial line, the signal processor and the receiver are all connected to the second connecting rod, one end of the coaxial line is electrically connected to the receiver, and the other end is electrically connected to the signal processor. The end of the first connecting rod away from the host is rotatably connected to the second connecting rod; the end of the cable away from the host is electrically connected to the signal processor. Since one end of the coaxial line is connected to the signal processor and the other end is connected to the receiver, the signal received by the receiver can be transmitted to the signal processor. One end of the cable is electrically connected to the host, and the other end of the cable is electrically connected to the signal processor, so the signal of the signal processor can be transmitted to the host. Because the first connecting rod is rotatably connected to the second connecting rod, the first connecting rod and the second connecting rod can be folded, which is highly flexible and easy to store. In addition, the length of the first connecting rod and the second connecting rod in the unfolded state is greater than the length of the first connecting rod and the second connecting rod in the folded state, and the distance between the receiver and the host can be adjusted by unfolding or folding the first connecting rod and the second connecting rod. When using the measuring device, the first connecting rod and the second connecting rod can be unfolded according to the obstruction (such as a cable) that blocks the receiver signal at the base station, and the position of the receiver can be adjusted to avoid the signal of the receiver being blocked, thereby improving the anti-electromagnetic interference and anti-blocking capabilities of the measuring device and improving the accuracy of the measured data. In addition, the bending radius of the coaxial line is usually greater than the bending radius of the cable, and the coaxial line does not cross the rotational connection between the first connecting rod and the second connecting rod. The coaxial line can not be bent, and the bending radius of the cable crossing the first connecting rod and the second connecting rod is small. In this way, the bending radius required by the measuring device during the folding process is small, and the volume of the measuring device can be reduced.

[0006] In combination with the first aspect, in some achievable ways, the first connecting rod includes a plurality of folding segments, and two adjacent folding segments are rotatably connected. The host is connected to the head ends of the plurality of folding segments, and the second connecting rod is connected to the tail ends of the plurality of folding segments. Thus, the length of the first connecting rod can be adjusted by rotating two adjacent folding segments, further reducing the volume of the measuring device, so that the measuring device can take into account the flexibility of packaging, transportation, and upper and lower base stations. The receiver can avoid the main radiation area in front of the antenna, thereby improving the anti-electromagnetic interference and anti-shielding capabilities of the measuring device.

[0007] In combination with the first aspect, in some achievable manners, the first connecting rod includes a plurality of telescopic sections, and two adjacent telescopic sections are slidably connected. The host is connected to the head ends of the plurality of telescopic sections, and the second connecting rod is connected to the tail ends of the plurality of telescopic sections. Thus, the length of the first connecting rod can be adjusted by sliding two adjacent telescopic sections, which is beneficial for the receiver to avoid the main radiation area in front of the antenna, and improves the anti-electromagnetic interference and anti-shielding capabilities of the measuring device.

[0008] In combination with the first aspect, in some achievable embodiments, the support assembly further includes an elastic member, and both opposite ends of the elastic member are connected to the cable. When the elastic member is in a free state, the cable located between the opposite ends of the elastic member is bent. When the first connecting rod and the second connecting rod are unfolded from a folded state to an unfolded state, the elastic member is stretched from the free state, and the portion of the cable located between the opposite ends of the elastic member that is bent is also stretched. In this way, the cable is prevented from being broken or damaged due to excessive force during the unfolding of the first connecting rod and the second connecting rod. In addition, the elastic member constrains the movement of the cable to prevent the cable from being entangled and affecting its extension.

[0009] In combination with the first aspect, in some achievable methods, the host includes a mounting surface and an assembly surface, the assembly surface is perpendicular to the mounting surface; the size of the mounting surface along the direction perpendicular to the assembly surface is L1; the size of the assembly surface along the direction perpendicular to the mounting surface is L2; ​​L1 and L2 are not equal. When the size of the position where the fixture is used to install the measuring device is L2, the assembly surface can be installed at the aforementioned position. Since L1 and L2 are not equal, the size of the mounting surface is not equal to the size of the position where the fixture is used to install the measuring device, then the mounting surface cannot be installed at the position where the fixture is used to install the aforementioned assembly surface. The mounting surface and the position where the fixture is used to assemble the surface can be avoided from fitting together. Avoiding installation errors of the fixture and the host, thus, the inequality of L1 and L2 has a fool-proof effect.

[0010] In combination with the first aspect, in some achievable methods, the extension direction of the first connecting rod and the extension direction of the second connecting rod are both parallel to the mounting surface. When the measuring device is used, when the mounting surface and one surface of the fixture are in contact, and any of the first assembly surface, the second assembly surface and the third assembly surface and another surface of the fixture are in contact. Because one end of the second connecting rod and the first connecting rod are connected to the second connecting rod to form a cantilever structure, the receiver is located on the second connecting rod, and the gravity of the receiver causes the coaxial line and the second connecting rod to have a downward bending moment. Since the extension direction of the first connecting rod and the extension direction of the second connecting rod are both parallel to the mounting surface, the bending moment only has a component force on the mounting surface, and the component force on the plane where the downward tilt angle is located is zero, which will not affect the size of the downward tilt angle measured by the receiver, so that the measurement is accurate.

[0011] In combination with the first aspect, in some achievable ways, the host further comprises a positioning part, which is connected to the assembly surface. The distance between the positioning part and the mounting surface is not equal to the distance between the positioning part and the surface of the host facing away from the mounting surface. The measuring device is connected to the fixture through the positioning part, and the mounting surface and the fixture are fitted. When the mounting surface and the fixture are fitted, the positioning part and the fixture are connected. Because the distance between the positioning part and the mounting surface is not equal to the distance between the positioning part and the surface of the host facing away from the mounting surface. If the mounting surface faces away from the fixture and does not fit therewith, the positioning part and the fixture cannot be connected. Whether the measuring device is installed correctly is determined by whether the positioning part can be connected to the fixture, so that the positioning part has a fool-proof function to avoid abnormal installation methods causing incorrect measurement results.

[0012] In combination with the first aspect, in some achievable ways, there are multiple assembly surfaces, each of which is perpendicular to the mounting surface. When in use, the mounting surface is fitted with a surface of the fixture. Any assembly surface and the fixture can be fitted. The measuring device and the fixture have multiple installation postures. They can be selected according to the installation site to better avoid obstructions such as cables, reduce interference, and increase the accuracy of the measurement results.

[0013] In combination with the first aspect, in some achievable embodiments, the measuring device further comprises: a support rod. One end of the support rod is rotatably connected to the first connecting rod, and the other end is detachably connected to the second connecting rod. Alternatively, one end of the support rod is rotatably connected to the second connecting rod, and the other end is detachably connected to the first connecting rod. When the first connecting rod and the second connecting rod are unfolded to a working state, the support rod and the second connecting rod are connected to form a stable triangle between the support rod, the first connecting rod and the second connecting rod, so as to avoid relative movement of the first connecting rod and the second connecting rod during the measurement process, thereby affecting the signal received by the receiver.

[0014] In the second aspect, an embodiment of the present application provides a measuring device. The measuring device comprises: a fixture and any one of the measuring devices provided in the first aspect, and the fixture and the measuring device are detachably connected. Since the aforementioned measuring device has high anti-electromagnetic interference and anti-shielding capabilities. Obviously, the measuring device also has the advantages of high anti-electromagnetic interference and anti-shielding capabilities and accurate measurement results.

[0015] In conjunction with the second aspect, in some achievable ways, the fixture includes a fixed arm, a tray and a connector. The fixed arm includes a first surface and a second surface that are arranged opposite to each other and parallel to each other. The tray is connected to the first surface; the connector is connected to the tray, and the distance between the connector and the first surface is not equal to the distance between the connector and the end of the tray away from the fixed arm. The host is detachably connected to the tray, and when the host and the tray are in a connected state, the host is in contact with the first surface. When the host and the tray are in a connected state, the host is in contact with the first surface, and the mounting surface of the host is in contact with the first surface. Because the distance between the connector and the first surface is not equal to the distance between the connector and the end of the tray away from the fixed arm, when the mounting surface is in contact with the first surface, the connector and the positioning portion can be connected. If the surface of the host facing away from the mounting surface is in contact with the first surface, the connector and the positioning portion cannot be connected. In this way, whether the connecting piece can be connected to the positioning part is used to determine whether the measuring device and the fixture are correctly installed, so that the connecting piece has a fool-proof function to avoid abnormal installation methods causing erroneous measurement results.

[0016] In conjunction with the second aspect, in some achievable ways, the fixed arm includes a main arm and a secondary arm, the two opposite surfaces of the main arm are the first surface and the second surface, the first surface and the second surface are respectively located on opposite sides of the main arm, one end of the secondary arm is connected to the first surface, and the other end extends to one side of the second surface, and there is a gap between the end surface of the main arm close to the secondary arm and the secondary arm. Because there is a gap between the end surface of the main arm close to the secondary arm and the secondary arm, the gap can accommodate the protrusion at the corner of the antenna, avoiding the existence of the protrusion causing the second surface and the measuring surface to fit poorly. Avoid inaccurate detection results due to poor fitting. In addition, the protrusion is located in the gap, which can reduce the wear on the protrusion of the antenna and reduce the wear on the corners of the antenna.

[0017] In combination with the second aspect, in some achievable embodiments, the clamp further includes a pad, and the extension direction of the pad is parallel to the second surface. The pad is located on the side of the main arm close to the second surface; the connecting end of the pad is detachably connected to the secondary arm, and the free end of the pad is located on the side of the secondary arm close to the main arm. Since the pad is located on the side of the main arm close to the second surface, the antenna and the pad are located on the same side of the main arm. When the clamp and the antenna are in a connected state, the free end of the pad abuts the antenna. In this way, the pad enables the main arm and the secondary arm to move along the extension direction of the pad, and the tray and the host connected to the tray can also move along the extension direction of the pad, so that the host is away from the antenna, avoiding the signal of the measuring device being blocked by obstructions such as cables and other components of the antenna accessories, thereby improving the measurement effect.

[0018] In combination with the second aspect, in some achievable methods, the clamp further includes a strap, one end of which is connected to an end of the main arm away from the secondary arm, and the other end is detachably connected to an end of the secondary arm away from the main arm. Alternatively, one end of the strap is connected to an end of the secondary arm away from the main arm, and the other end is detachably connected to an end of the main arm away from the secondary arm. Because the secondary arm and the main arm are rigid structures. During the bundling process, the secondary arm and the main arm of the rigid structure can support the strap to wrap around the periphery of the antenna, and one end of the auxiliary strap is transferred to the other end. This effectively improves the problem that the periphery of the antenna is large and difficult to transfer flexible straps. It can be used for antennas with larger circumferences to improve disassembly and assembly efficiency.

[0019] In combination with the second aspect, in some achievable ways, the fixture further comprises a stopper, the stopper is connected to the first surface, the stopper is located on one side of the tray, and the end surface of the stopper facing the tray is perpendicular to the first surface. When the host is in a connected state with the tray, the stopper is in contact with the end surface of the tray facing the host. When the host is in a connected state with the tray, the stopper surface of the stopper can prevent the host and the tray from sliding relative to each other. The stopper surface is in contact with the host, which can prevent the host from tipping over in the direction of the stopper surface or tipping over in the direction away from the stopper surface, making the measurement result more accurate. In addition, the stopper surface of the stopper also has an indicating function. In the process of connecting the host and the tray, when the stopper surface of the stopper abuts and fits the host, it proves that the fit between the host and the tray is high, the installation posture is correct, and it is conducive to the rapid installation of the host.

[0020] In a third aspect, an embodiment of the present application provides a clamp. The clamp includes a fixed arm, a tray, and a connecting piece. The fixed arm includes a first surface and a second surface that are arranged opposite to each other and parallel to each other. The tray is connected to the first surface. The connecting piece is connected to the tray, and the distance between the connecting piece and the first surface is not equal to the distance between the connecting piece and the end of the tray away from the fixed arm.

[0021] When the host and the tray are in a connected state, the host and the first surface are in contact. The connector is connected to the host. Because the distance between the connector and the first surface is not equal to the distance between the connector and the end of the tray away from the fixed arm. When the mounting surface is in contact with the first surface, the connector and the host can be connected. If the surface of the host away from the mounting surface is in contact with the first surface, the connector and the host cannot be connected. In this way, whether the measuring device and the fixture are correctly installed is determined by whether the connector can be connected to the positioning part. The connector has an anti-fool function, so that the fixture has an anti-fool function to avoid abnormal installation methods causing incorrect measurement results.

[0022] In conjunction with the third aspect, in some achievable methods, the fixed arm includes a main arm and a secondary arm, the two opposite surfaces of the main arm are the first surface and the second surface, the first surface and the second surface are respectively located on opposite sides of the main arm, one end of the secondary arm is connected to the first surface, and the other end extends to one side of the second surface, and there is a gap between the end surface of the main arm close to the secondary arm and the secondary arm. Because there is a gap between the end surface of the main arm close to the secondary arm and the secondary arm, the gap can accommodate the protrusion at the corner of the antenna, avoiding the existence of the protrusion causing the second surface and the measuring surface to fit poorly. Avoid inaccurate detection results due to poor fitting. In addition, the protrusion of the antenna is located in the gap, which can reduce the wear on the protrusion of the antenna. Reduce wear on the corners of the antenna.

[0023] In combination with the third aspect, in some achievable methods, the fixture further includes: a stopper, the stopper is connected to the first surface, the stopper is located on one side of the tray, and the end surface of the stopper facing the tray is perpendicular to the first surface. When the host is in a connected state with the tray, the stopper is in contact with the end surface of the tray facing the host. The stopper surface can prevent the host and the tray from sliding relative to each other. The stopper surface is in contact with the host, which can prevent the host from tipping over toward the stopper surface or away from the stopper surface, making the measurement result more accurate. In addition, the stopper surface of the stopper also has an indicating function. During the connection between the host and the tray, when the stopper surface of the stopper abuts against the host, it proves that the fit between the host and the tray is high, the installation posture is correct, and it is conducive to the rapid installation of the host.

[0024] In combination with the third aspect, in some feasible ways, the clamp further comprises a strap, one end of which is connected to one end of the main arm away from the secondary arm, and the other end is detachably connected to one end of the secondary arm away from the main arm. Alternatively, one end of the strap is connected to one end of the secondary arm away from the main arm, and the other end is detachably connected to one end of the main arm away from the secondary arm. Because the secondary arm and the main arm are rigid structures. During the bundling process, the secondary arm and the main arm of the rigid structure can support the strap to surround the periphery of the antenna, and one end of the auxiliary strap is transferred to the other end. This effectively improves the problem that the periphery of the antenna is large and difficult to transfer flexible straps. It can be applied to antennas with larger circumferences to improve disassembly and assembly efficiency.

[0025] In combination with the third aspect, in some achievable embodiments, the clamp further includes a pad, and the extension direction of the pad is parallel to the second surface. The pad is located on the side of the main arm close to the second surface; the connecting end of the pad is detachably connected to the secondary arm, and the free end of the pad is located on the side of the secondary arm close to the main arm. When the clamp and the antenna are in a connected state, the free end of the pad abuts the antenna. In this way, the pad enables the main arm and the secondary arm to move along the extension direction of the pad. The tray and the host connected to the tray can also move along the extension direction of the pad. Keep the host away from the antenna to avoid obstructions such as cables and other components of the antenna accessories from blocking the signal of the measuring device, thereby improving the measurement effect.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0034] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0035] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0036] Figure 1 is a schematic diagram of the structure of a base station. Figure 1 The base station includes an antenna 20 and a measuring device 10, and the measuring device 10 and the antenna 20 are detachably connected. The antenna 20 has a measuring surface 21, and the measuring surface 21 is a plane. The measuring device 10 and the measuring surface 21 are in contact with each other. When the posture of the antenna 20 needs to be measured, the measuring device 10 and the antenna 20 are connected, the measuring device 10 and the measuring surface 21 are in contact with each other, and the measuring device 10 measures the posture of the antenna 20. After the measurement is completed, the measuring device 10 and the antenna 20 are separated.

[0037] like Figure 1 As shown, the measuring device 10 includes a fixture 200 and a measuring device 100, and the fixture 200 and the measuring device 100 are detachably connected. The fixture 200 and the antenna 20 are detachably connected. When the posture of the antenna 20 needs to be measured, the fixture 200 and the antenna 20 are first connected, and the fixture 200 and the measuring surface 21 are fitted. Then the fixture 200 and the measuring device 100 are connected so that the measuring device 100 and the measuring surface 21 are parallel.

[0038] The embodiment of the present application does not display the data of the antenna 20 measured by the measuring device 10. Exemplarily, the measuring device 10 is used to measure the angle α between the measuring plane 21 of the antenna 20 and the vertical direction, and the angle α is also called the downtilt angle. The measuring device 10 is also used to measure the azimuth β of the antenna 20.

[0039] The downtilt angle is the angle between the antenna under test and the plumb line. The downtilt angle directly affects the beam shape on the ground and is a very critical parameter. The sources of the downtilt angle error include: the production and assembly accuracy of the measuring device 100, the clamping and fixing deviation at the measurement site, and the electrical performance of the measuring device 100. The azimuth angle is the angle between the direction of the antenna under test and the true north direction.

[0040] Figure 2 Schematic diagram of the structure of the antenna measuring instrument 01 and the antenna body 02 in the related art. Figure 2 The antenna measuring instrument 01 and the antenna body 02 are detachably connected. During the measurement process, the antenna measuring instrument 01 may be blocked, resulting in inaccurate measurement results. In addition, the poor fit between the antenna measuring instrument 01 and the antenna body 02 may result in inaccurate measurement results.

[0041] Figure 3 This is a schematic diagram of the structure of the measuring device 10 provided in the embodiment of the present application. Figure 3 The measuring device 100 includes a host 110, a supporting component 120 and a receiving component 130. The host 110 is connected to the supporting component 120, and the receiving component 130 is connected to the supporting component 120.

[0042] The support assembly 120 includes a first connecting rod 121 and a cable 122 (shown by a dotted line), and the first connecting rod 121 and the cable 122 are connected. The embodiment of the present application does not limit the connection method between the first connecting rod 121 and the cable 122. In some embodiments, the cable 122 is buried in the first connecting rod 121. In this way, the cable 122 is better stored in the first connecting rod 121 to avoid clutter in the support assembly 120. In other embodiments, the cable 122 is wound around the outside of the first connecting rod 121, which can facilitate the inspection and replacement of the cable 122. One end of the first connecting rod 121 is connected to the host 110, and one end of the cable 122 is electrically connected to the host 110.

[0043] The receiving assembly 130 includes a second connecting rod 131, a receiver 133, a signal processor 132 and a coaxial line 134 (shown by a dotted line). The receiver 133, the signal processor 132 and the coaxial line 134 are all connected to the second connecting rod 131. One end of the coaxial line 134 is connected to the signal processor 132, and the other end is connected to the receiver 133. The end of the first connecting rod 121 away from the host 110 is rotatably connected to the second connecting rod 131. The end of the cable 122 away from the host 110 is electrically connected to the signal processor 132.

[0044] Since one end of the coaxial line 134 is connected to the signal processor 132, and the other end is connected to the receiver 133. Then the signal received by the receiver 133 can be transmitted to the signal processor 132. One end of the cable 122 is electrically connected to the host 110, and the other end of the cable 122 is electrically connected to the signal processor 132. Then the signal of the signal processor 132 can be transmitted to the host 110. Because the first connecting rod 121 is rotatably connected to the second connecting rod 131. Therefore, the first connecting rod 121 and the second connecting rod 131 can be folded, with high flexibility and easy to store. In addition, the length of the first connecting rod 121 and the second connecting rod 131 in the unfolded state is greater than the length of the first connecting rod 121 and the second connecting rod 131 in the folded state, and the distance between the receiver 133 and the host 110 can be adjusted by unfolding or folding the first connecting rod 121 and the second connecting rod 131. When using the measuring device 100, the first connecting rod 121 and the second connecting rod 131 can be unfolded according to the obstructions (such as cables or poles) that block the signal of the receiver 133 at the base station, and the position of the receiver 133 can be adjusted to avoid the signal of the receiver 133 being blocked, thereby improving the accuracy of the measurement data.

[0045] In addition, the bending radius of the coaxial line 134 is usually greater than 20 mm (millimeter), which is much larger than the bending radius of the folding mechanism cable of 10 mm. The coaxial line 134 can be connected to the second connecting rod 131, so that the coaxial line 134 can not cross the rotation connection between the first connecting rod 121 and the second connecting rod 131, and the coaxial line 134 can not be bent. The bending radius of the cable 122 spanning the first connecting rod 121 and the second connecting rod 131 is small, and can be much smaller than 10 mm. In this way, the measuring device 100 provided in the present application has a large range of selectable bending radius at the connection between the first connecting rod 121 and the second connecting rod 131, and can even be unrestricted.

[0046] The aforementioned bending radius is the curvature radius. Taking the coaxial line 134 as an example, the coaxial line 134 is bent to the extreme to form an arc, and the radius of the arc is. Alternatively, a shorter section of the coaxial line 134 is replaced by an arc segment, and the radius of the arc segment is the bending radius.

[0047] In the embodiment of the present application, the receiver 133 is also called GPS (global positioning system). Figure 3 In the example of FIG. 1 , the receiving assembly 130 includes two receivers 133 and two coaxial lines 134. Both the two receivers 133 and the two coaxial lines 134 are connected to the second connecting rod 131. One receiver 133 is connected to the signal processor 132 via one coaxial line 134. The two receivers 133 are located at opposite ends of the second connecting rod 131, respectively.

[0048] The embodiment of the present application does not limit the connection method between the coaxial line 134 and the second connecting rod 131. In some embodiments, the coaxial line 134 is embedded in the second connecting rod 131. In other embodiments, the coaxial line 134 is located outside the second connecting rod 131, and the coaxial line 134 is connected to the second connecting rod 131 through a binding member.

[0049] The embodiment of the present application does not limit the manner in which the first connecting rod 121 and the second connecting rod 131 are rotatably connected. For example, the first connecting rod 121 and the second connecting rod 131 are rotatably connected via a hinge.

[0050] Figure 3 In the embodiment, the first connecting rod 121 includes a plurality of folding segments 1211, two adjacent folding segments 1211 are rotatably connected, the main unit 110 is connected to the head ends of the plurality of folding segments 1211, and the second connecting rod 131 is connected to the tail ends of the plurality of folding segments 1211. In this way, the length of the first connecting rod 121 can be adjusted by rotating two adjacent folding segments 1211. The volume of the measuring device 100 is further reduced. The measuring device 100 is made flexible in terms of packaging, transportation, and upper and lower base stations. Before use, a single person can quickly unfold the measuring device 100 to 2-3 times of its original volume, and the receiver 133 can avoid obstructions such as the top cover of the antenna under test. In addition, if the receiver 133 is located in the main radiation zone in front of the antenna under test, the signal received by the receiver 133 will be subject to electromagnetic interference from the main radiation zone, affecting the measurement result. In the embodiment of the present application, the length of the first connecting rod 121 can be adjusted by rotating two adjacent folding sections 1211 so that the receiver 133 connected to the second connecting rod 131 avoids the main radiation area in front of the antenna, thereby improving the anti-electromagnetic interference and anti-shielding capabilities of the measuring device 100.

[0051] The head end of the aforementioned multiple folding segments 1211 refers to the end of the folding segment 1211 closest to the mainframe 110 among the multiple folding segments 1211, and the head end of the multiple folding segments 1211 is the end of the first connecting rod 121 close to the mainframe 110. The tail end of the aforementioned multiple folding segments 1211 refers to the end of the folding segment 1211 farthest from the mainframe 110 among the multiple folding segments 1211, and the tail end of the multiple folding segments 1211 is the end of the first connecting rod 121 farthest from the mainframe 110.

[0052] It is understandable that in other embodiments, the first connecting rod 121 can be telescopically arranged, so that the length of the first connecting rod 121 can also be adjusted. For example, the first connecting rod 121 includes a plurality of telescopic sections, two adjacent telescopic sections are slidably connected, the host 110 is connected to the head ends of the plurality of telescopic sections, and the second connecting rod 131 is connected to the tail ends of the plurality of telescopic sections. The length of the first connecting rod 121 can also be adjusted by sliding two adjacent telescopic sections. This is beneficial for the receiver 133 to avoid the main radiation area in front of the antenna, and improves the anti-electromagnetic interference and anti-shielding capabilities of the measuring device 100.

[0053] Similarly, the head end of the multiple telescopic segments refers to the end of the telescopic segment closest to the mainframe among the multiple telescopic segments, and the head end of the multiple telescopic segments is the end of the first connecting rod close to the mainframe. The tail end of the aforementioned multiple telescopic segments refers to the end of the telescopic segment farthest from the mainframe among the multiple telescopic segments, and the tail end of the multiple telescopic segments is the end of the first connecting rod far away from the mainframe.

[0054] Figure 3 In the example, the measuring device 100 further includes a strut 140, one end of which is rotatably connected to the first connecting rod 121, and the other end of the strut 140 is detachably connected to the second connecting rod 131. In this way, when the first connecting rod 121 and the second connecting rod 131 are unfolded to the working state, the strut 140 and the second connecting rod 131 are connected to form a stable triangle between the strut 140, the first connecting rod 121 and the second connecting rod 131. This prevents the first connecting rod 121 and the second connecting rod 131 from moving relative to each other during the measurement process, thereby affecting the signal received by the receiver 133. Alternatively, in other embodiments, one end of the strut 140 is rotatably connected to the second connecting rod 131, and the other end of the strut 140 is detachably connected to the first connecting rod 121, which can also have the function of stabilizing the first connecting rod 121 and the second connecting rod 131.

[0055] Figure 4 This is a schematic diagram of the structure of the first connecting rod 121 and the cable 122 provided in an embodiment of the present application. Figure 4 In the embodiment, the measuring device 100 further includes an elastic member 160, and opposite ends of the elastic member 160 are connected to the cable 122. When the elastic member 160 is in a free state, the portion of the cable 122 between the opposite ends of the elastic member 160 is bent. Thus, when the elastic member 160 is in a stretched state, the portion of the cable 122 between the opposite ends of the elastic member 160 is stretched by the elastic member 160.

[0056] For example, when the first link 121 and the second link 131 are unfolded from the folded state to the unfolded state, the elastic member 160 is stretched from the free state, and the cable 122, which is bent between the two opposite ends of the elastic member 160, is also stretched. In this way, the cable 122 is prevented from being broken or damaged due to excessive force during the unfolding of the first link 121 and the second link 131. In addition, the elastic member 160 constrains the movement of the cable 122 to prevent the cable 122 from being entangled and affecting the stretching.

[0057] In some embodiments, the elastic member 160 and the cable 122 are both located in the first connecting rod 121 for easy storage, so as to prevent the elastic member 160 and the cable 122 from being entangled with the second connecting rod 131 and other components. Exemplarily, the elastic member 160 is a spring.

[0058] As described above, when the measuring device 100 is installed, the measuring device 100 and the measuring surface 21 (such as Figure 1The host 110 includes a mounting surface 111 (as shown in FIG. Figure 3 As shown), when in use, the mounting surface 111 and the fixture 200 are in contact with each other, and the fixture 200 and the measuring surface 21 are in contact with each other.

[0059] In some embodiments of the present application, the installation posture of the measuring device 100 can be increased to prevent the shielding objects (such as poles or cables) near the antenna 20 from blocking the signal of the measuring device 100. Figure 5 An exemplary description is given.

[0060] Figure 5 A schematic diagram of the structure of the host 110 and the fixture 200 provided in an embodiment of the present application. Figure 5 In the embodiment, the host 110 has three assembly surfaces, namely, a first assembly surface 101, a second assembly surface 102, and a third assembly surface 103. The first assembly surface 101 is located at an end of the host 110 away from the first connecting rod 121. The second assembly surface 102 and the third assembly surface 103 are arranged opposite to each other, and both the second assembly surface 102 and the third assembly surface 103 are perpendicular to the mounting surface 111.

[0061] During the installation process, the mounting surface 111 is fitted with one surface of the fixture 200, and any one of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 is fitted with another surface of the fixture 200. In other words, the two surfaces of the host 110 are fitted with the two surfaces of the fixture 200, respectively. This ensures that the mounting surface 111 and the fixture 200 do not deviate, thereby avoiding inaccurate measurements of data such as the downtilt angle and the azimuth angle caused by the deviation of the mounting surface 111 and the fixture 200. In addition, any one of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 can be fitted with the fixture 200, and the measuring device 100 and the fixture 200 have at least three installation postures. For example, Figure 5 Any of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 can be installed downwards. It can be selected according to the installation site to better avoid shielding objects such as cables, reduce interference, and increase the accuracy of the measurement results.

[0062] Please return to Figure 3 In some embodiments of the present application, the extension direction of the first connecting rod 121 and the extension direction of the second connecting rod 131 are both parallel to the mounting surface 111. As mentioned above, the first connecting rod 121 and the second connecting rod 131 are rotatably connected. In this way, during the relative rotation of the first connecting rod 121 and the second connecting rod 131, the extension direction of the first connecting rod 121 and the extension direction of the second connecting rod 131 will change. However, the extension direction of the first connecting rod 121 and the extension direction of the second connecting rod 131 are always in the same plane. The extension direction of the first connecting rod 121 and the extension direction of the second connecting rod 131 are both in Figure 3In other words, the plane where the extension direction of the first connecting rod 121 and the extension direction of the second connecting rod 131 in the folded state are located is the A surface, and the first connecting rod 121 and the second connecting rod 131 in the unfolded state are located on the A surface. Obviously, the extension direction of the coaxial line 134 is located on the A surface. And because the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 are all perpendicular to the mounting surface 111. Then the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 are all perpendicular to the A surface.

[0063] When the mounting surface 111 is fitted with one surface of the fixture 200, and any of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 is fitted with another surface of the fixture 200, the A surface is parallel to the mounting surface 111. Because one end of the second connecting rod 131 is connected to the first connecting rod 121 to form a cantilever structure, the receiver 133 is located on the second connecting rod 131, and the gravity of the receiver 133 causes the coaxial line 134 and the second connecting rod 131 to have a downward bending moment. Since the A surface is parallel to the mounting surface 111, the bending moment has a component force only on the A surface, and the component force on the plane where the downward tilt angle is located is zero, which will not affect the size of the downward tilt angle measured by the receiver 133, so that the measurement is accurate.

[0064] by Figure 3 The three installation postures of the measuring device 100 are described by taking the connection between the measuring device 100 and the fixture 200 as an example. The first installation posture: the mounting surface 111 of the host 110 is in contact with the fixture 200, the first assembly surface 101 faces downward and is in contact with the fixture 200, and the two receivers 133 are distributed at intervals in the horizontal direction. The second installation posture: the mounting surface 111 of the host 110 is in contact with the fixture 200, the second assembly surface 102 faces downward and is in contact with the fixture 200, and the two receivers 133 are distributed at intervals in the vertical direction. The third installation posture: the mounting surface 111 of the host 110 is in contact with the fixture 200, the third assembly surface 103 faces downward and is in contact with the fixture 200, and the two receivers 133 are distributed at intervals in the vertical direction. The directions of the two receivers 133 in the second installation posture and the third installation posture are opposite. In the above three installation postures, the distribution directions of the two receivers 133 are all on the A surface. The downtilt angles and azimuth angles of the two receivers 133 are equal. When switching the installation posture, the downtilt angle and azimuth angle can be obtained without additional calculation.

[0065] It is understandable that the aforementioned perpendicularity between the first assembly surface 101 and the A surface does not limit the angle between the first assembly surface 101 and the A surface to 90°. Exemplarily, the angle between the first assembly surface 101 and the A surface may be 85°-95°, for example, 85°, 86°, 87°, 88°, 90°, 92°, 93° or 95°, etc. The angle between the second assembly surface 102 and the A surface and the angle between the third assembly surface 103 and the A surface are similar, and the description of perpendicularity, etc. in the following text is similar and will not be repeated.

[0066] Figure 5 In the example of , the measuring device 100 further includes a positioning portion 150, and the measuring device 100 is connected to the fixture 200 via the positioning portion 150. The positioning portion 150 is connected to the assembly surface. For example, the positioning portion 150 is connected to any assembly surface of the first assembly surface 101, the second assembly surface 102, and the third assembly surface 103. The distance d1 between the positioning portion 150 and the mounting surface 111 and the distance d2 between the positioning portion 150 and the surface of the host 110 away from the mounting surface 111 are not equal.

[0067] Taking the connection between the positioning part 150 and the first assembly surface 101 as an example, the measuring device 100 is connected to the fixture 200 through the positioning part 150, and the mounting surface 111 and the fixture 200 are fitted. When the mounting surface 111 and the fixture 200 are fitted, the positioning part 150 and the fixture 200 are connected. If the mounting surface 111 is away from the fixture 200 and is not fitted thereto, the positioning part 150 and the fixture 200 cannot be connected because d1 and d2 are not equal. Whether the measuring device 100 is installed correctly is determined by whether the positioning part 150 can be connected to the fixture 200, so that the positioning part 150 has a fool-proof function to avoid abnormal installation methods causing incorrect measurement results.

[0068] The embodiment of the present application does not limit the structure of the positioning portion 150. It is set according to the connection method of the measuring device 100 and the fixture 200. In some embodiments, the positioning portion 150 can be a threaded hole. The measuring device 100 and the fixture 200 are connected by bolts. In other embodiments, the positioning portion 150 can be a buckle or other structure.

[0069] For the convenience of description, it is defined that the x direction is perpendicular to the mounting surface 111 , the y direction is perpendicular to the second mounting surface 102 , and the y direction is perpendicular to the third mounting surface 103 .

[0070] Figure 5 In the example, the size of the mounting surface 111 along the y direction is L1, and the sizes of the first mounting surface 101, the second mounting surface 102 and the third mounting surface 103 along the x direction are all L2. L1 and L2 are not equal.

[0071] When the size of the position where the fixture 200 is used to install the measuring device 100 is L2, any of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 can be installed at the aforementioned position. Since L1 and L2 are not equal, the size of the mounting surface 111 is not equal to the size of the position where the fixture 200 is used to install the measuring device 100, and then the mounting surface 111 cannot be installed at the position where the fixture 200 is used to install the aforementioned assembly surface. It can avoid that the mounting surface 111 and the position where the fixture 200 is used to fit with any of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 fit together, and avoid the fixture 200 and the host 110 from being installed incorrectly. In this way, the size L1 of the mounting surface 111 along the y direction and the size L2 of the first assembly surface 101, the second assembly surface 102 and the third assembly surface 103 along the x direction are not equal, which has a fool-proof effect.

[0072] In some embodiments, the host 110 can measure according to the assembly surface that fits the fixture 200. Exemplarily, the host 110 processes the data received by the signal processor 132. The data processing method includes, for example: judging the installation posture of the host 110 according to the signal received by the receiver 133, and then correcting and compensating the data received by the receiver 133 according to the installation posture. In order to balance the deviations introduced by various links such as assembly or use under different installation postures, the accuracy is maximized. For example, the aforementioned first installation posture adopts one correction compensation, the second installation posture adopts another correction compensation, and the third installation posture adopts another correction compensation.

[0073] In other embodiments of the present application, the measuring device 100 and the fixture 200 may have only one installation posture. For example, only one of the first assembly surface 101, the second assembly surface 102, and the third assembly surface 103 is connected to the fixture 200. For example, the fixture 200 is connected only through the first assembly surface 101. Alternatively, the measuring device 100 and the fixture 200 may have two installation postures. For example, the second assembly surface 102 or the third assembly surface 103 may be connected to the fixture 200.

[0074] As mentioned above, the measuring device 100 is connected to the antenna 20 via the fixture 200. The fixture 200 needs to ensure that the measuring device 100 and the antenna 20 are relatively stable.

[0075] Figure 6 A schematic diagram of the structure of the clamp 200 provided in an embodiment of the present application. Figure 6 In the embodiment, the fixture 200 includes a fixing arm 210, a tray 220 and a connecting member 230. The host 110 and the tray 220 are detachably connected, and the connecting member 230 and the positioning portion 150 (such as Figure 5The fixed arm 210 includes a first surface 211 and a second surface 212, and the first surface 211 and the second surface 212 are arranged opposite to each other and parallel to each other. The tray 220 is connected to the first surface 211, and the tray 220 is connected to the connecting member 230.

[0076] The distance between the connecting member 230 and the first surface 211 is c1. The distance between the connecting member 230 and the end of the tray 220 away from the fixed arm 210 is c2. c1 and c2 are not equal. When the host 110 and the tray 220 are in a connected state, the host 110 and the first surface 211 are in contact. The mounting surface 111 of the host 110 and the first surface 211 are in contact.

[0077] Because c1 and c2 are not equal, when the mounting surface 111 and the first surface 211 are in contact, the connector 230 and the positioning portion 150 can be connected. If the surface of the host 110 facing away from the mounting surface 111 is in contact with the first surface 211, the connector 230 and the positioning portion 150 cannot be connected. In this way, whether the connector 230 can be connected to the positioning portion 150 is used to determine whether the measuring device 100 and the fixture 200 are correctly installed, so that the connector 230 has a fool-proof function to avoid abnormal installation methods causing incorrect measurement results.

[0078] In the embodiment of the present application, the end of the tray 220 away from the fixed arm 210 refers to the tray 220 used to fit the host 110 (such as Figure 5 200 is far away from the end of the fixed arm 210. For example, in some embodiments, the fixture 200 may also be provided with a stop bar 221, which is protruding from the surface of the tray 220 and connected to the tray 220. When the tray 220 is connected to the host 110, the stop bar 221 and the assembly surface of the host 110 (for example, the first assembly surface 101) do not fit. Obviously, the distance c2 between the connector 230 and the end of the tray 220 away from the fixed arm 210 does not include the size of the stop bar 221.

[0079] The embodiment of the present application does not limit the connection method between the tray 220 and the first surface 211. In some embodiments, the connection method between the tray 220 and the first surface 211 is a detachable connection method such as a snap connection or a screw connection. The tray 220 and the main arm 213 can be detached for easy carrying. Alternatively, in other embodiments, the connection method between the tray 220 and the first surface 211 is a fixed connection such as welding.

[0080] In some embodiments, multiple connection positions for connecting the tray 220 can be set on the first surface 211 as required, and the multiple connection positions are arranged at intervals along the extension direction of the main arm 213. One of the aforementioned multiple connection positions can be selected to connect to the tray 220 according to the shielding condition of the shielding objects near the antenna 20.

[0081] The embodiment of the present application does not limit the structure of the connector 230, and can be set according to the connection method between the positioning portion 150 and the connector 230. For example, in an embodiment where the positioning portion 150 and the connector 230 are screwed, the connector 230 can be set as a hole structure. In an embodiment where the positioning portion 150 and the connector 230 are snap-connected, the connector 230 can be a buckle structure. Figure 6 In the example, the connecting member 230 is a bar-shaped hole, and the screw passes through the bar-shaped hole and is connected with the positioning portion 150 (such as Figure 5 For example, during the connection between the positioning part 150 and the connecting member 230, a screw is connected to the positioning part 150, and the screw slides in the strip hole until the mainframe 110 and the tray 220 are properly installed, and then the screw is tightened. In this way, the strip hole has the function of adjusting the relative position of the mainframe 110 and the tray 220.

[0082] Figure 6 In the example, the fixed arm 210 includes a main arm 213 and a secondary arm 214. The two opposite surfaces of the main arm 213 are the aforementioned first surface 211 and the second surface 212. One end of the secondary arm 214 is connected to the first surface 211. The other end of the secondary arm 214 extends to one side of the second surface 212 of the main arm 213, and the main arm 213 and the secondary arm 214 are connected to form an L-shape. There is a gap 215 between the end surface of the main arm 213 close to the secondary arm 214 and the secondary arm 214. When the fixture 200 and the antenna 20 are attached, the first surface 211 is attached to the main body 110 of the measuring device 100, the second surface 212 of the main arm 213 is attached to the measuring surface 21 of the antenna 20, and the secondary arm 214 is in contact with the antenna 20.

[0083] Please return to Figure 1 In some usage scenarios, there may be a protrusion 23 at the transition position between the surface of the antenna 20 that is used to abut against the main arm 213 and the surface of the antenna 20 that is used to abut against the secondary arm 214. Because there is a gap 215 between the end surface of the main arm 213 close to the secondary arm 214 and the secondary arm 214, the gap 215 can accommodate the protrusion 23 of the antenna 20, avoiding the existence of the protrusion 23 causing the second surface 212 and the measuring surface 21 to fit poorly. Avoid inaccurate detection results due to poor fitting. In addition, the protrusion 23 is located in the gap 215, which can reduce the wear on the protrusion 23 of the antenna 20. Reduce the wear on the corners of the antenna 20.

[0084] Figure 6In the example, the fixed arm 210 is an L-shaped structure. The main arm 213 is in the shape of a thin plate, and the secondary arm 214 is in the shape of a thin plate. The main arm 213 and the secondary arm 214 are perpendicular to each other. The L-shaped structure has a larger area, and the measuring surface 21 of the antenna 20 and the side surfaces adjacent to the measuring surface 21 are both in contact with the L-shaped structure. The pressure on the antenna 20 is smaller, especially for antennas whose outer shells are made of plastic materials such as fiberglass, which reduces the clamping deformation of the antenna outer shell. The embodiment of the present application does not limit the materials of the main arm 213 and the secondary arm 214. In some embodiments, in order to reduce the weight of the main arm 213 and the secondary arm 214, the material of the main arm 213 and the secondary arm 214 may be an aluminum alloy profile.

[0085] Figure 6 In the embodiment, the clamp 200 further includes a stopper 240, and the stopper 240 is connected to the first surface 211. The stopper 240 is located at one side of the tray 220, and the end surface of the stopper 240 facing the tray 220 is perpendicular to the first surface 211. When the host 110 and the tray 220 are in a connected state, the end surface of the stopper 240 facing the tray 220 is in contact with the host 110. For ease of description, the end surface of the stopper 240 facing the tray 220 is defined as a stopper surface 241, and the stopper surface 241 is perpendicular to the first surface 211. When the host 110 and the tray 220 are in a connected state, the stopper surface 241 is in contact with the host 110.

[0086] For example, when the host 110 Figure 5 The posture and Figure 6 When the fixture 200 shown is connected, the mounting surface 111 of the host 110 and the first surface 211 (such as Figure 6 The first assembly surface 101 is in contact with the tray 220, and the second assembly surface 102 is in contact with the stop surface 241.

[0087] When the host 110 and the tray 220 are in a connected state, the stop surface 241 of the stop part 240 can prevent the host 110 and the tray 220 from sliding relative to each other. The stop surface 241 fits with the host 110, which can prevent the host 110 from tipping toward the stop surface 241 or away from the stop surface 241, making the measurement result more accurate. In addition, the stop surface 241 of the stop part 240 also has an indication function. During the connection between the host 110 and the tray 220, when the stop surface 241 of the stop part 240 abuts and fits with the host 110, it proves that the fit between the host 110 and the tray 220 is high, the installation posture is correct, and it is conducive to the rapid installation of the host 110.

[0088] The stopper 240 is connected to the first surface 211, and the secondary arm 214 is also connected to the first surface 211. In some embodiments, Figure 6As shown, the secondary arm 214 and the stopper 240 are connected as an integrally formed part. It is understood that in other embodiments, the secondary arm 214 and the stopper 240 can be independently provided. For example, the secondary arm 214 and the stopper 240 are spaced apart. Alternatively, the secondary arm 214 and the stopper 240 can be located on both sides of the tray 220, respectively.

[0089] Figure 6 In the example of , the clamp 200 further includes a pad 250, and the extension direction of the pad 250 is parallel to the second surface 212. The pad 250 has two opposite ends, one end is a connecting end 251, and the other end is a free end 252. The pad 250 is located on one side of the second surface 212 of the main arm 213. The connecting end 251 of the pad 250 is detachably connected to the secondary arm 214. The free end 252 of the pad 250 is located on a side of the secondary arm 214 close to the main arm 213.

[0090] Since the pad 250 is located on one side of the second surface 212 of the main arm 213, the antenna 20 and the pad 250 are located on the same side of the main arm 213. When the fixture 200 and the antenna 20 are in a connected state, the free end 252 of the pad 250 abuts against the antenna 20. In this way, the pad 250 causes the main arm 213 and the secondary arm 214 to move along the extension direction of the pad 250, and the part where the main arm 213 and the antenna 20 are in contact also moves accordingly. The tray 220 and the host 110 connected to the tray 220 can also move along the extension direction of the pad 250, so that the host 110 and the receiver 133 connected to the host 110 are away from the antenna 20. Under the condition that the main arm 213 and the antenna 20 are in contact, and the host 110 and the fixture 200 are connected, the measuring device 100 can measure data, and it can avoid that the components of the antenna 20, such as cables and other shielding objects, block the signal of the measuring device 100, thereby improving the measurement effect.

[0091] For example, if the secondary arm 214 is connected to the pad 250, the signal of the measuring device 100 connected to the tray 220 may be blocked by the shielding object. The secondary arm 214 is connected to the pad 250, and the tray 220 and the measuring device 100 are moved together along the extension direction of the pad 250, and the moving distance is the dimension of the pad 250 in the extension direction. The shielding object blocks the signal of the measuring device 100.

[0092] The embodiment of the present application does not limit the connection method of the pad 250 and the secondary arm 214. For example, the pad 250 and the secondary arm 214 are connected in a detachable manner such as a snap connection or a screw connection, which facilitates the removal of the pad 250 and the secondary arm 214 for carrying, and whether to install the pad 250 and the secondary arm 214 can be selected according to whether there is an obstruction near the antenna 20.

[0093] As described above, in the embodiment where a plurality of connection positions for connecting the tray 220 are provided on the first surface 211, one of the plurality of connection positions can be selected to connect with the tray 220 and the pad 250 can be provided according to the shielding condition of shielding objects near the antenna 20, so that more relative positions can be selected between the measuring device 100 and the antenna 20, and a relative position with fewer shielding objects can be selected, so as to further reduce the influence of shielding objects on the measurement results.

[0094] When the fixed arm 210 and the antenna 20 are in abutment, in order to stabilize the connection between the clamp 200 and the antenna 20. In some embodiments, the clamp 200 further includes a strap 260, one end of which is connected to an end of the main arm 213 away from the secondary arm 214, and the other end is detachably connected to an end of the secondary arm 214 away from the main arm 213. In this way, the strap 260 can bind the main arm 213 and the secondary arm 214 to the antenna 20 to achieve a stabilizing effect. Avoid the clamp 200 and the antenna 20 from being offset. This affects the positional relationship between the antenna 20 and the measuring device 100, resulting in inaccurate measurement.

[0095] In addition, when the measurement personnel are installing the fixture 200, they can hold the end of the secondary arm 214 away from the main arm 213, wrap the band 260 around the antenna 20, and then connect the end of the secondary arm 214 away from the main arm 213 and the band 260. In this way, the circumference of the antenna 20 is equal to the sum of the length of the main arm 213, the length of the secondary arm 214, and the length of the band 260. When the measurement personnel are installing the fixture 200, if the size of the outer periphery of the antenna 20 is large, one end of the band 260 may not be easily transferred to the other end due to its flexibility. Because the secondary arm 214 and the main arm 213 are rigid structures. During the bundling process, the rigid structure of the secondary arm 214 and the main arm 213 can support the band 260 to surround the outer periphery of the antenna 20, and one end of the auxiliary band 260 is transferred to the other end. The problem that the outer periphery of the antenna 20 is large and it is not easy to transfer the flexible band 260 is effectively improved. It can be applied to antennas with larger circumferences to improve the efficiency of disassembly and assembly.

[0096] For example, if the sum of the lengths of the secondary arm 214 and the main arm 213 is 30 cm (centimeter), during the installation of the fixture 200, the measurement personnel hold the secondary arm 214 at one end away from the main arm 213, and the position of the flexible strap 260 is 30 cm away from the hand-held portion, and the flexible strap 260 can be pulled to wrap around the periphery of the antenna 20 and connect to the hand-held portion. In this way, the rigid support capacity of the secondary arm 214 and the main arm 213 can be fully utilized to improve the efficiency of assembly and disassembly.

[0097] The embodiment of the present application does not limit the manner in which the strap 260 is detachably connected to the end of the secondary arm 214 away from the main arm 213. For example, a nut is provided at the end of the secondary arm 214 away from the main arm 213, and the end of the strap 260 is sleeved on the nut to achieve detachable connection between the strap 260 and the end of the secondary arm 214 away from the main arm 213. The nut occupies less space. If there is an obstruction near the antenna 20, it can pass through the gap between the obstruction and the antenna 20. The applicable scope of the clamp 200 is increased.

[0098] Alternatively, in some embodiments, one end of the strap 260 is connected to an end of the secondary arm 214 away from the primary arm 213, and the other end is detachably connected to an end of the primary arm 213 away from the secondary arm 214. This also has the advantage of accurate measurement.

[0099] The measuring device 10 provided in the embodiment of the present application is not limited to being used to measure the installation data of the antenna 20. It is understandable that the measuring device 10 can be used to measure the angles of other structures, for example, to measure the angles of building structures, etc. The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
