Description

Technical Field

[0001] This application relates to the field of aerospace test and launch technology, and more specifically, to an adjustable antenna fixing fixture. Background Technology

[0002] In recent years, with the continuous development of my country's aerospace industry, launch site testing operations have become increasingly standardized, mainly including the installation of antennas and instruments at the launch site. During rocket testing, a measurement system relay antenna needs to be installed. Its main function is to transmit analog wireless signals so that the rocket can receive analog signals from the ground. Therefore, the professional depth and practical skills of the personnel in this position must meet high standards and strict requirements.

[0003] During rocket test launches, the measurement system's relay antenna is fixed to an iron railing, and the antenna is installed and secured by operators using wire or electrical cable. The relay antenna plays a crucial role during rocket power-on testing. In the aerospace test launch process, antenna installation is time-consuming and relatively complex. Before installation, two operators are required for the antenna installation process: one installs the antenna bracket, and the other uses a white cloth bag to prevent fall damage. If the operators haven't received adequate training, the operation is quite difficult. The wire binding method is complex; improper binding can lead to product falls and personnel injuries. Furthermore, during rocket power-on testing, the antenna position needs to be adjusted multiple times, which is inconvenient, affecting both the standardization of product operation and reducing operational efficiency.

[0004] Traditional antenna installation typically requires the collaborative efforts of multiple people. From an efficiency standpoint, the binding methods are complex, and improper binding can lead to product drops and personnel injuries. Furthermore, the need for multiple adjustments during antenna installation is inconvenient. These issues, to some extent, affect the progress of antenna installation. Therefore, designing an adjustable antenna fixing fixture that adapts to existing antenna installation methods has been a widely recognized technical challenge in the industry. Utility Model Content

[0005] The purpose of this application is to provide an adjustable antenna fixing fixture to solve the problems of cumbersome and time-consuming antenna installation and disassembly by operators, and to reduce the safety hazards of low installation efficiency and high safety risks during operation.

[0006] To achieve the above objectives, this utility model provides an adjustable antenna fixing fixture for clamping onto the antenna's anchoring structure. The antenna fixing fixture includes a first clamp and a second clamp that can open and close in opposite directions. A hinge is provided between the first clamp and the second clamp on the same side.

[0007] The first clamp and the second clamp each include opposing curved plates and connecting plates disposed on both sides of the opposing curved plates. The opposing gaps on the opposing curved plates constitute the clamping space of the anchoring structure, and the connecting plates are locked and fixed by locking components.

[0008] The first clamp has a connecting hole on its clamping plate for mounting an antenna.

[0009] In an optional embodiment, the first clamp and the second clamp are both provided with mounting grooves for mounting the hinge on the connecting plate located on the same side. The mounting grooves include U-shaped notches on the connecting plate.

[0010] In an optional embodiment, the hinge includes a hinge strip with an elongated cylindrical outer contour. The hinge strips are arranged in pairs, and a through hole and an adjustment slot are provided on the hinge strip. The through hole is located at the connection root of the hinge strip, and the adjustment slot is located on the side of the through hole and extends along the length direction of the hinge strip.

[0011] In an optional embodiment, the locking member includes a deflection bolt with a hand-tightening nut that can deflect with the second clamp as a base point. The root of the deflection bolt is provided with a flat spherical connecting block. The connecting block is provided with a connecting through hole, and a connecting pin is inserted into the connecting through hole. The connecting plate of the second clamp is provided with a U-shaped receiving groove, and the connecting block is rotatably received in the receiving groove.

[0012] In an optional embodiment, the connecting pin located on the mounting side of the hinge strip passes through the through hole and the connecting through hole, and both ends of the connecting pin are fixed on the connecting plate of the second clamp, and the connecting pin is clearance-fitted with the through hole and the connecting through hole.

[0013] In an optional embodiment, a limiting pin is provided in the mounting groove of the first clamp, which passes through the adjustment channel. The two ends of the limiting pin are fixed on the connecting plate of the first clamp, and the limiting pin is in clearance fit with the adjustment channel.

[0014] In an optional embodiment, the connecting plate of the first clamp is provided with a locking groove that allows the deflection bolt to deflect into it. The locking groove and the receiving groove have the same shape and are vertically corresponding.

[0015] In an optional embodiment, the deflection bolt located on the hinge plate mounting side includes one, and the receiving groove and the locking groove are disposed at the center of the connecting plate.

[0016] In an optional embodiment, the deflection bolts located on the other side of the hinge plate include two, and the receiving groove and the locking groove include two sets, and the two sets of receiving grooves and locking grooves are symmetrically arranged on both sides of the connecting plate.

[0017] In an optional embodiment, the hand-tightening nut is screwed onto the screw rod of the deflection bolt, the screw rod including a smooth section at the top end, on which a C-shaped locking pin is inserted.

[0018] The adjustable antenna fixing fixture in this application solves the problems of complex binding, inconvenient adjustment, and multiple-person operation in traditional antenna installation through adjustable clamp structure, quick locking mechanism and anti-loosening design.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] The adjustable antenna fixing fixture in this application is mainly used for the installation of the relay antenna of the rocket measurement system. It aims to solve the problems of traditional antenna installation, such as the need for multiple people to cooperate, complex binding, inconvenient adjustment, and high safety risks.

[0037] See Figure 1 and combined Figures 2-3 The adjustable antenna fixing fixture of this utility model is used to clamp the antenna onto the anchoring structure, such as clamping it onto an iron railing, to provide a structural basis for the installation of the antenna.

[0038] The adjustable antenna fixing fixture includes a first clamp 1 and a second clamp 2, which are connected by a hinge 3 located between the same side to form an opposing opening and closing structure.

[0039] Both the first clamp 1 and the second clamp 2 include opposing bending plates 10 and connecting plates 20. The opposing bending plates 10 protrude in opposite directions, and the gap between the first clamp 1 and the second clamp 2 forms a clamping space for clamping anchoring structures such as iron railings. The connecting plates 20 are located on both sides of the opposing bending plates 10 and are locked and fixed by locking members 4.

[0040] On one of the clamping components, specifically on the clamping plate 10 of the first clamping clamp 1 located at the top, a connecting hole 30 is provided for directly mounting the antenna. The connecting hole 30 is specifically a through hole structure with internal threads. The antenna body can be fixed in the connecting hole 30 by bolts welded to the antenna body or similar rod-shaped fasteners with external threads at the end. This enables the antenna body to be connected on the fixing fixture after the fixing fixture is clamped and fixed on the iron railing. Furthermore, it enables the bolts or similar rod-shaped fasteners with external threads at the end to pass through the connecting plate 20 and abut against the iron railing, ensuring the overall connection stability.

[0041] To prevent debris from entering the clamping space through the connection hole 30 when the tooling is not in use, a hand-tightening nut is threaded onto the connection hole 30 in the idle state. When in use, only the hand-tightening nut needs to be removed.

[0042] The hinge 3 is mounted on the connecting plate 20 on the same side of the first clamp 1 and the second clamp 2. With the connecting hole 30 located at the top of the first clamp 1, the root of the hinge 3 is connected to the connecting plate 20 of the second clamp 2 located at the bottom, forming a movable hinged relationship between the first clamp 1 and the second clamp 2. Simultaneously, the hinge 3 maintains a limited-movement connection with the first clamp 1, allowing the first clamp 1 to move along the hinge 3. This enables the first clamp 1 to adjust its relative opening and closing state with the second clamp 2 without disengaging from the second clamp 2.

[0043] From the installation angle of the hinge 3, the connecting plate 20 on the same side of the first clamp 1 and the second clamp 2 is provided with a U-shaped cross-section mounting groove 40 to accommodate the hinge 3. To facilitate the installation of the hinge 3, the mounting groove 40 is specifically a U-shaped cross-section notch groove provided on the connecting plate 20. The notch groove allows the second clamp 2 to slide along the length of the hinge 3, and allows the first clamp 1 and the second clamp 2 to deflect relative to the notch groove, thereby enhancing the flexibility of the two clamps when connected. It enables the first clamp 1 to be opened at the maximum angle relative to the second clamp 2, thus meeting the clamping requirements of anchoring structures of different sizes.

[0044] The hinge component 3 includes a pair of hinge plates 31. The outer contour of the hinge plate 31 is an elongated oval shape. The hinge plate 31 is provided with a through hole 311 and an adjustment slot 312. The through hole 311 is located at the connecting root of the hinge plate 31 and is used to pass through the connecting pin 5. It is mainly used for the installation of the root of the hinge plate 31 on the connecting plate 20 of the second clamp 2. The adjustment slot 312 allows the limiting pin 6 located at the mounting groove 40 on the connecting plate 20 of the first clamp 1 to pass through. By fixing the two ends of the limiting pin 6 to the two sides of the mounting groove 40 of the connecting plate 20 of the first clamp 1 and fixing it to the connecting plate 20 of the first clamp 1, and further, the limiting pin 6 and the adjustment slot 312 are in clearance fit, which allows the first clamp 1 to slide along the length of the adjustment slot 312, thereby adjusting the opening and closing range of the two clamp components.

[0045] The adjusting groove 312 is located on the side of the through hole 311 and extends along the length of the hinge plate 31. Combined with the notched mounting groove 40, it allows the clamps to adjust their opening angle when not engaged. The notched mounting groove 40, along with the clearance fit between the connecting pin 5 and the limiting pin 6 and the through hole 311 and adjusting groove 312 respectively, allows both the first clamp 1 and the second clamp 2 to simultaneously shift relative to the hinge plate 31 towards the groove opening, thus ensuring flexible adjustment of the relative position between the two clamps.

[0046] The locking component 4 includes a deflection bolt 41 and a hand-tightening nut 42. The root of the deflection bolt 41 is provided with a flat ball-shaped connecting block 411, and the connecting block 411 has a connecting through hole 412.

[0047] The flattened spherical connecting block 411 has a structure similar to an abacus, which can deflect in the receiving groove 50 in the direction of the notch according to the deflection bolt 41, making it easy to open and close the clamp and adjust it.

[0048] The connecting plate 20 of the second clamp 2 is provided with a U-shaped accommodating groove 50. The connecting block 411 is accommodated in the accommodating groove 50 and is connected to the connecting hole 412 through the connecting pin 5. The connecting pin 5 and the connecting hole 412 are in a clearance fit relationship, which allows the root of the deflection bolt 41 to move and engage with the connecting pin 5. This allows the deflection bolt 41 to deflect relative to the second clamp 2 toward the notch with the second clamp 2 as the base point and the connecting pin 5 as the axis of rotation, thus maintaining the unlocked state.

[0049] Based on the connection of the root of the hinge plate 31 to the first clamp 1, in order to simplify the structural composition, the connecting pin 5 located on the mounting side of the hinge plate 31 passes through the through hole 311 on the hinge plate 31 and the connecting through hole 412 on the connecting block 411, and simultaneously connects the deflection bolt 41 on the mounting side of the hinge plate 31 and the hinge plate 31.

[0050] Specifically, the two ends of the connecting pin 5 are fixed on the connecting plate 20 of the second clamp 2, and the connecting pin 5 is clearance-fitted with the through hole 311 and the connecting through hole 412, which does not affect the movable hinge relationship between the deflection bolt 41 and the hinge strip 31 relative to the second clamp 2.

[0051] A locking groove 60 is provided on the connecting plate 20 of the first clamp 1. The locking groove 60 has the same shape as the receiving groove 50 on the second clamp 2 and corresponds to it vertically. It is used to accommodate the deflection bolt 41 to deflect into it and to complete the locking by screwing the locking nut downward.

[0052] Specifically, the adjustable antenna fixing fixture in this application includes a closed side where the first clamp 1 and the second clamp 2 cannot be disassembled, and a free side that can be opened and closed. According to the hinge plate 31 described above, the mounting side of the hinge plate 31 constitutes the closed side of the fixture. This side, through the mounting groove 40 in the form of a U-shaped cross-section notch and the receiving groove 50, as well as the limiting cooperation between the first clamp 1 and the adjustment through groove 312, allows for adjustment of the engagement range between the first clamp 1 and the second clamp 2.

[0053] The other side of the hinged strip 31 forms the free side, where the first clamp 1 and the second clamp 2 can be fully opened, allowing a section of the iron railing along the axial direction, that is, the length corresponding to the width of the clamping plate 10, to enter the clamping space of the two clamps.

[0054] During the clamping and fixing of the iron railing, since the root of the hinge plate 31 is connected to the second clamp 2, the free side can be opened first. Combined with the movable hinge relationship, the first clamp 1 and the second clamp 2 can be opened to their maximum extent. Of course, the opening range can be flexibly adjusted according to the specific dimensions of the iron railing. After the relative fastening action is performed and the iron railing is clamped, the movement of the first clamp 1 relative to the second clamp 2 along the adjusting groove 312 on the hinge plate 31 allows the first clamp 1 to reach a suitable clamping range relative to the second clamp 2. Then, the deflection screw... Bolt 41 is deflected around connecting pin 5, so that the screw part of deflecting bolt 41 enters locking groove 60. Then, the hand-tightening nut 42 of the wing nut is manually turned downward. The lower part of the hand-tightening nut 42 is provided with washer 44. By turning the hand-tightening nut 42, the washer 44 is pressed onto the connecting plate 20, so that the hand-tightening nut 42 can be locked on the plate surface of the connecting plate 20 of the first clamp 1. Thus, the clamping and locking on the connecting plate 20 on both sides of the clamp is achieved, and the iron railing is clamped and fixed, so that the adjustable antenna fixing fixture forms a relatively stable anchoring structure foundation.

[0055] The hand-tightening nut 42 is screwed onto the thread of the deflection bolt 41. Its position can be adjusted by turning it. Of course, before clamping, the hand-tightening nut 42 needs to be kept above the locking groove 60 after the clamp is engaged. This will not be elaborated here.

[0056] The top of the screw is provided with a smooth section 413, and a C-shaped locking pin 43 is inserted into the smooth section 413 to limit the hand-tightening nut 42 and prevent the hand-tightening nut 42 from falling off the top of the hand-tightening nut 42.

[0057] Regarding the distribution of the locking element 4: On the mounting side of the hinge plate 31, i.e. the hinged closed side, a deflection bolt 41 is provided. The receiving groove 50 and the locking groove 60 are located in the center of the connecting plate 20, which allows the hinge plate 31 to be located on both sides of the deflection bolt 41.

[0058] On the other side, the non-hinged free side, two deflection bolts 41 are provided, and the receiving groove 50 and locking groove 60 are symmetrically arranged on both sides of the connecting plate 20.

[0059] The above configuration allows for three-point locking of the locking element 4, ensuring stable and reliable locking.

[0060] During the use of the fixture, firstly, open the fixture: the operator holds the first clamp 1 and the second clamp 2, and rotates them outward around the hinge point of the hinge member 3 to open the clamps and expand the clamping space. Align the opened fixture with the anchoring structure, such as the iron railing, so that the iron railing enters the clamping space formed by the clamping plate 10. Close the first clamp 1 and the second clamp 2, so that the clamping plate 10 clamps the iron railing. According to the size of the iron railing, and in conjunction with the movable relationship of the first clamp 1 equivalent to the hinge strip 31 adjustment slot 312, adjust the clamping range to adapt the fixture to different sizes. Deflect the deflection bolt 41 into the locking groove 60 of the first clamp 1, and then tighten the hand nut 42 to make the two clamps tightly clamp the anchoring structure, completing the clamping.

[0061] The antenna body is fixed by bolts or similar rod-shaped screws with external threads at the end to the connecting hole 30 of the first clamp 1, thus completing the antenna fixation.

[0062] To adjust the antenna position, simply remove the antenna body, loosen the hand-tightening nut 42, move the clamp, then reposition the iron railing corresponding to the antenna position, clamp and lock it again, and then screw the antenna body back on. No extensive disassembly and assembly work is required.

[0063] The adjustable antenna fixing fixture in this application, through clamp clamping, hinge adjustment and quick locking design, enables single-person operation of antenna installation, simplifies the process, improves safety and efficiency, reduces safety risks, and meets the high standards required for aerospace testing and launch.

[0064] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
