DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the utility model, and is not used to limit the utility model.

[0029] It should be noted that the orientations or positional relationships indicated by various orientation terms are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0030] In addition, the terms "first", "second", etc. in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence; and, in the absence of conflict, the embodiments of the utility model and the features in the embodiments can be arbitrarily combined with each other. It should be understood by those of ordinary skill in the art that the diagrams provided herein are for illustrative purposes, and the diagrams are not necessarily drawn to scale. It should be understood that when an element is said to be "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or there can be an intermediate element.

[0031] The antenna sensor can be installed and fixed on the top of the base station antenna in the following ways:

[0032] (1) Install and fix by punching

[0033] A hole is punched on the outer shell at the top of the antenna, and the antenna sensor is installed and fixed on the top of the base station antenna using the hole on the antenna shell. This installation and fixing method requires drilling a hole in the antenna shell, which may cause water leakage on rainy days and affect the waterproofness and airtightness of the antenna.

[0034] (2) Use rolled belt binding to install and fix

[0035] The antenna sensor is bound and fixed to the base station antenna using a rolled tape. This installation and fixing method will cause the antenna sensor to shake, affect the acquisition of antenna parameters, and then cause abnormal result reporting.

[0036] (3) Installation and fixation by welding

[0037] The method of adding welding points to the base station antenna shell and the antenna sensor shell respectively, and fixing the antenna sensor by welding, will increase the difficulty of installation. High-altitude work and welding not only have high requirements on the installation environment, but also on the welding technology of the installation workers, which will undoubtedly increase the installation cost and installation time.

[0038] (4) Installation and fixation by gluing

[0039] Glue is applied to the antenna sensor housing and the base station antenna housing respectively, and then the antenna sensor is directly bonded to the base station antenna. Since the glue application method may result in uneven glue application, the uneven glue application may cause measurement errors, which in turn may lead to inaccurate antenna parameter acquisition. In addition, the glue application method may increase material and labor costs, and increase the workload of the installer.

[0040] Based on the problems existing in the prior art, the utility model provides a universal fixing structure for antenna sensors which is easy to install, has good stability and strong versatility.

[0041] The present utility model provides an antenna sensor fixing structure. Figures 1 to 3 As shown, the antenna sensor fixing structure 100 includes: two sets of clamping components 102 and a connecting member 101 .

[0042] The two sets of clamping components 102 are arranged opposite to each other and the spacing is adjustable. Each set of clamping components 102 includes a clamping plate 1021. The two clamping plates 1021 in the two sets of clamping components 102 are clamped on the two sides of the antenna body of the base station antenna. The clamping plates 1021 are provided with injection holes 10211 for injecting glue. The antenna body has a front surface, a back surface, a top surface, a bottom surface, and left and right side surfaces.

[0043] The connector 101 is used to connect two sets of clamping components 102. The connector 101 is located behind the antenna body, and the antenna sensor 200 is fixed thereon. The antenna sensor 200 is also located behind the antenna body to form a back-mounted antenna sensor. The antenna body of the base station antenna can also be called an antenna box.

[0044] In this embodiment, the antenna sensor is fixed by a connector located at the back of the antenna body of the base station antenna, and then is clamped on the two sides of the antenna body of the base station antenna by two clamping plates of two sets of clamping assemblies, so that the antenna sensor can be fixed at the back of the antenna body. Compared with the existing fixing method of fixing the antenna sensor on the top of the base station antenna, the antenna sensor fixing method in this embodiment is less difficult to construct. In the face of extreme weather such as wind, rain, ice and snow, the antenna body can shield and protect the antenna sensor at the back to reduce the impact of the external environment on the antenna sensor.

[0045] Moreover, the two clamps are first clamped on the two sides of the antenna body of the base station antenna, and then glue is injected between the inner side of the clamp and the side of the antenna body through the glue injection holes respectively arranged on the two clamps, so that the clamp and the antenna body can be bonded and fixed more firmly, thereby improving wind resistance, shock resistance, and good stability.

[0046] In addition, by adjusting the spacing between the two sets of clamping components, antenna bodies of different sizes can be adapted, which is basically suitable for all base station antennas in the existing network. Therefore, it has good versatility, simple structure, easy installation and maintenance, and is easy to install. The installation process will not cause any damage to the antenna casing.

[0047] In a specific embodiment, the two clamping assemblies 102 are symmetrically arranged about the antenna body, and the two clamping plates 1021 in the two clamping assemblies 102 are inclined in an inward-facing shape. As for the inclination angle of the two clamping plates 1021, it can be set and adjusted by those skilled in the art according to actual conditions.

[0048] In this embodiment, the two clamping plates of the two sets of clamping assemblies are symmetrically arranged with respect to the antenna body and are slightly inclined inwardly in an O-shaped manner, so as to increase the clamping force between the clamping assemblies and the antenna body.

[0049] In a specific embodiment, the area of ​​the clamping surface of the inner side of the clamping plate 1021 for clamping the side of the antenna body is 90 cm 2 ~110cm 2 Preferably, the area of ​​the clamping surface is 100 cm 2 .

[0050] The clamping surface can be rectangular, circular, or other shapes suitable for clamping on the side of the antenna body. The smaller the area of ​​the clamping surface, the less secure the antenna sensor will be. On the contrary, if the area of ​​the clamping surface is too large, it will cause waste of materials and costs. Therefore, it is critical to select a clamping surface of appropriate size. In this embodiment, the area of ​​the clamping surface is selected to be 90 cm 2 ~110cm 2 , which can take into account both stability and cost.

[0051] In a specific embodiment, Figure 4 As shown, the clamping surface of the inner side of the clamping plate 1021 for clamping the side of the antenna body is provided with multiple evenly distributed protrusions 10212. Moreover, since the glue injection hole 10211 is provided on the clamping plate 1021, which occupies a small part of the inner side of the clamping plate, a few protrusions (such as 2 protrusions) are missing, and the remaining protrusions are evenly distributed on the clamping surface.

[0052] The diameter of each protrusion 10212 is 2 mm to 3 mm, preferably 3 mm, and the height is 1 mm to 2 mm, preferably 1 mm.

[0053] In this embodiment, evenly distributed protrusions are provided on the inner side of the clamping plate. One function is to increase the friction between the inner surface of the clamping plate and the side surface of the antenna body. Another function is that the evenly distributed protrusions provide a space for injecting glue between the inner side of the clamping plate and the side surface of the antenna body, and provide a glue guide function. When the glue is injected through the glue injection hole on the back of the clamping plate (i.e., the outer side of the clamping plate), the guide energy passing through the evenly distributed protrusions can be more evenly filled between the inner side of the clamping plate and the side surface of the antenna body.

[0054] Since the glue is evenly distributed between the clamping plate and the antenna body, the clamping plate and the antenna body can be bonded and fixed more firmly, thereby improving the wind resistance and shock resistance of the antenna sensor; at the same time, the evenly distributed glue makes the contact surface between the clamping plate and the antenna body smoother, thereby minimizing the negative impact on the antenna measurement results.

[0055] In a specific embodiment, Figure 4 As shown, a plurality of observation holes 10213 are provided on the inner edge of the clamping plate 1021, and each observation hole 10213 extends outward to the surrounding sides of the clamping plate 1021. The clamping plate 1021 has an inner surface, an outer surface and surrounding sides.

[0056] Further, the cross section of the observation hole is semicircular; accordingly, the observation hole is semi-cylindrical.

[0057] In this embodiment, if the clamping surface of the clamping plate is a rectangular clamping surface, observation holes can be respectively set at the four corners of the rectangular clamping surface, and each observation hole extends to the sides of the clamping plate. When the clamping plate is clamped on the side of the antenna body, four observation holes can be seen on the sides of the clamping plate. When injecting glue, the glue condition can be checked through the observation holes to determine whether the injection is completed.

[0058] In a specific embodiment, Figure 3 and Figure 5 As shown, a plurality of reinforcing members 10214 are disposed on the outer side of the splint 1021 for increasing the strength of the splint.

[0059] One end of a plurality of reinforcing members 10214 is gathered at one end of the outer side of the clamping plate 1021, and the remaining parts of the plurality of reinforcing members 10214 extend from one end of the outer side of the clamping plate 1021 to the other end, and the remaining parts of each reinforcing member 10214 are arranged at equal intervals, and each reinforcing member 10214 is arranged perpendicular to the outer surface of the clamping plate. The height of the remaining part of each reinforcing member 10214 gradually decreases from one end of the outer side of the clamping plate to the other end until the height is zero.

[0060] In a specific embodiment, Figure 4 As shown, the glue injection hole 10211 is located in the central area of ​​the clamping plate 1021 .

[0061] In this embodiment, the glue injection hole is located at the center of the clamping plate. The glue injected from the outside to the inside through the glue injection hole in the center of the clamping plate can be more evenly distributed between the inner side of the clamping plate and the side of the antenna body to provide stronger adhesion.

[0062] Moreover, injecting glue through the glue injection hole on the back of the splint can save the use of glue, which can reduce costs and reduce the negative impact on the environment.

[0063] During the actual installation, the installer can hold the antenna sensor to fix the structure with one hand and inject glue with the other hand. At this time, the back of the splint is facing the installer, and the glue injection hole on the back of the splint is convenient for the installer to inject glue. The convenient operation of the installer can not only save installation time, but also reduce installation errors, providing a prerequisite for the subsequent accurate acquisition of antenna parameters.

[0064] In an optional embodiment, the glue injection hole 10211 includes a glue injection inlet located on the outside of the splint and a glue injection outlet located on the inside of the splint, and a fastener is provided at the glue injection inlet, and the fastener is used to lock the glue injection head inserted into the glue injection hole 10211 through the glue injection inlet.

[0065] In this embodiment, in order to facilitate glue injection, the diameter of the glue injection hole should be slightly larger than the outer diameter of the glue injection head. In addition, a fastener is provided at the entrance of the glue injection hole. After the glue injection head is inserted into the glue injection hole, the glue injection head is locked by the fastener to prevent the glue injection head from loosening during glue injection. After the glue injection is completed, the fastener is loosened and the glue injection head is pulled out of the glue injection hole.

[0066] The fasteners may be existing fasteners with a spiral structure.

[0067] In another optional embodiment, the glue injection hole 10211 is provided with an internal thread, the glue injection head is provided with an external thread, and the glue injection head is connected to the glue injection hole 10211 through threads.

[0068] In this embodiment, the glue injection head is fixed in the glue injection hole by means of a threaded connection, which can also effectively prevent the glue injection head from loosening during glue injection, and the structure is simple.

[0069] In a specific implementation, the connecting member 101 is a connecting rod, and the clamping plate 1021 is sleeved on the connecting rod.

[0070] like Figure 3 As shown, each set of clamping assembly 102 further includes: a positioning sleeve 1022 and a tightening sleeve 1023 sleeved on the connecting rod.

[0071] The inner surface of the clamping plate 1021 faces the side of the antenna body, and the outer end of the clamping plate 1021 is connected to one end of the positioning sleeve 1022. The other end of the positioning sleeve 1022 is provided with an elastic sheet 1024, and the outer surface of the positioning sleeve 1022 is provided with an external thread corresponding to the area between the elastic sheet 1024 and the clamping plate 1021, and the inner surface of the tight sleeve 1023 is provided with an internal thread. The tight sleeve 1023 is rotated so that its inner surface presses the elastic sheet 1024 and is connected to the outer surface of the positioning sleeve 1022 through threads to achieve the positioning purpose.

[0072] In this embodiment, the clamping plate is fixed on the connecting rod by means of a positioning sleeve, a tightening sleeve and an elastic sheet.

[0073] Furthermore, if Figure 3 As shown, the elastic sheet 1024 is provided with multiple pieces, and the multiple elastic sheets 1024 are arranged around the connecting rod, one end of each elastic sheet 1024 is connected to the other end of the positioning sleeve 1022, and the other end of each elastic sheet 1024 is bent toward the direction close to the connecting rod. The elastic sheet 1024 is made of elastic material.

[0074] In this embodiment, by arranging multiple curved elastic sheets at the end of the positioning sleeve, the outer diameter of the end of the positioning sleeve forms a tapered design, which makes it easier to extend into the tight hoop sleeve and be caught by the tight hoop sleeve; moreover, the multiple elastic sheets are compressed to provide a better positioning effect.

[0075] In a specific embodiment, Figure 3 As shown, each set of clamping assembly 102 further includes: a damping sleeve 1025. The damping sleeve 1025 is sleeved on the connecting rod and is located between the connecting rod and the elastic sheet 1024 at the other end of the positioning sleeve 1022. When the tight hoop 1023 is rotated so that its inner wall presses the elastic sheet 1024 on the positioning sleeve 1022, the elastic sheet 1024 will press the damping sleeve 1025 to be fixed on the connecting rod.

[0076] The damping sleeve 1025 is made of elastic material, which may be silicone material.

[0077] In this embodiment, a damping sleeve is provided between the connecting rod and the positioning sleeve, and the damping sleeve can only slide on the connecting rod but cannot rotate around the connecting rod, so that a flexible connection is formed between the connecting rod and the positioning sleeve, thereby avoiding mechanical resonance.

[0078] In a specific embodiment, an anti-retraction structure is provided at the ends of the tightening sleeve 1023 and the positioning sleeve 1022 close to each other, and the anti-retraction structure is used to prevent the tightening sleeve 1023 from rotating in the opposite direction and retreating after the tightening sleeve 1023 and the positioning sleeve 1022 are threadedly connected.

[0079] Specifically, the anti-retraction structure may include a raised one-way bone provided on the tight hoop 1023 and a raised positioning bone provided on the positioning sleeve 1022. The positioning bone on the positioning sleeve 1022 protrudes outward at the end close to one side of the tight hoop, and a clamping groove is provided at the end close to one side of the positioning sleeve on the tight hoop 1023. The tight hoop 1023 is rotated until the protruding part of the positioning bone on the positioning sleeve 1022 slides into the clamping groove of the one-way bone and is clamped by the clamping groove of the one-way bone and cannot be rotated in the reverse direction.

[0080] In addition, the anti-retraction structure may also adopt structures such as a plug or a stop screw, and the present invention does not limit this.

[0081] In this embodiment, since both sets of clamping assemblies are provided with anti-retraction structures, it is ensured that the two clamping plates are always kept in a clamped state, preventing the clamping assemblies from loosening and preventing the clamping force of the two clamping plates on the two sides of the antenna body from weakening, thereby preventing the relative position of the antenna sensor and the antenna to be measured from changing, and will not change the measurement reference, and will not affect the measurement accuracy of the antenna sensor.

[0082] In a specific embodiment, Figure 1 As shown, the connecting rod is a hollow rod-shaped structure, and its cross section is oval or rectangular (square or rectangular).

[0083] In this embodiment, the cross-section of the connecting rod is not circular, but elliptical or rectangular, which mainly serves to initially limit the clamping assembly mounted on the connecting rod to prevent the clamping assembly from rotating and sliding on the connecting rod. Of course, the cross-section of the connecting rod can also be of other shapes as long as it can play a limiting role.

[0084] Specifically, the connecting rod can be made of a hollow stainless steel tube. Of course, the connecting rod can also be made of other materials as long as a certain strength is guaranteed.

[0085] In a specific embodiment, Figure 2 As shown, the antenna sensor 200 includes a sensor main control box 201 and two left and right GPS antenna boxes 202. Two positioning holes are respectively provided at both ends of the connecting rod, and the two GPS (Global Positioning System) antenna boxes 202 of the antenna sensor 200 are fixed to the connecting rod through the two positioning holes. The sensor main control box 201 of the antenna sensor 200 is fixed to the middle of the connecting rod by a snap-on method.

[0086] In this embodiment, the left and right GPS antenna boxes are respectively installed at the two positioning holes at both ends of the connecting rod by screws. The GPS antenna box is a part of the antenna sensor, and is equipped with a GPS antenna for receiving GPS satellite signals. The middle sensor main control box is fixed to the middle of the connecting rod by snapping, and a small hole is opened in the middle position of the connecting rod. The shape of the small hole can be elliptical. After the communication cable led out of the sensor main control box 201 extends into the inside of the connecting rod through the small hole, it is divided into two parts and extends in the inside of the connecting rod toward its two ends, until it extends from the two ends of the connecting rod, and then connected to the left and right GPS antenna boxes 202, so as to realize the communication between the sensor main control box 201 and the GPS antenna boxes 202 on the left and right sides.

[0087] The antenna sensor fixing structure provided by the embodiment of the utility model fixes the antenna sensor through the connecting piece located behind the antenna body of the base station antenna, and can mount antenna sensors of different sizes and specifications according to different needs, and then clamp the two clamping plates of the two sets of clamping components on the two sides of the antenna body of the base station antenna, so as to realize the back-hanging installation of the antenna sensor, so that the antenna sensor can be flexibly installed at any position behind the antenna body according to the spatial position of the base station antenna on site, and the installer does not have to climb to the top of the antenna to install, so that the installer who works at high altitude can install it more easily, and the construction difficulty is correspondingly reduced. Moreover, the injection of glue between the inner side of the clamping plate and the side of the antenna body further improves the wind and earthquake resistance of the back-hanging antenna sensor, and the stability is better. Furthermore, by adjusting the spacing between the clamping components on the left and right sides, it can be applied to base station antennas of various sizes at present, and has strong versatility. Compared with the existing antenna sensor installation and fixing methods, the fixing structure provided by the utility model has the advantages of low construction difficulty, good stability, simple structure, convenient installation, strong versatility and high reliability.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
