Description

Technical Field

[0001] This utility model relates to the field of antenna mounting bracket technology, specifically a mobile communication device antenna mounting bracket. Background Technology

[0002] In wireless communication systems, antenna brackets are critical infrastructure used to fix and support the antenna body, ensuring it is in the optimal position for stable signal reception and transmission. Traditional antenna brackets mostly use rigid structures directly fixed to the ground or building. While this ensures stability during use, its position is difficult to adjust once determined, lacking mobility.

[0003] In practical applications, scenarios such as temporary communication support, field exploration, scientific research, military exercises, and emergency disaster relief often require rapid deployment, flexible adjustment, or evacuation of communication equipment based on the situation on site. To meet mobility requirements, some existing technologies have developed mobile supports equipped with wheels. However, most of these designs have significant drawbacks: some solutions use permanently mounted wheels, which are always exposed at the bottom of the support. While this facilitates movement, when in fixed use, the small contact area between the support and the ground and the high center of gravity result in insufficient stability, weak wind resistance, and potential safety hazards. Other solutions employ liftable wheel mechanisms, but their operation is usually cumbersome, requiring individual adjustment of the locking device or lifting mechanism of each wheel. This leads to low deployment and retrieval efficiency, hinders rapid deployment and retrieval, and the complex mechanical structure reduces reliability in harsh environments.

[0004] Therefore, there is an urgent need in this field for a new type of antenna mounting bracket that can effectively resolve the contradiction between mobility and deployment stability, and enable rapid and reliable switching between two working states to meet the dual requirements of equipment flexibility and reliability in modern communication applications. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a portable communication antenna mounting bracket, comprising a base frame, on which a vertical frame is fixed. A sleeve is installed in the middle of the vertical frame for inserting the antenna body. Multiple sets of foldable rolling components are installed below the base frame. The base frame has a deep groove for accommodating the rolling components. Each rolling component includes a wheel seat and a roller mounted on the end of the wheel seat. One end of the wheel seat is hinged to the deep groove via a pin. A limiting ring is provided in the middle of the sleeve. A ring seat that can slide along the sleeve is fitted on the sleeve and is located below the limiting ring. A fastening nut for limiting the downward position of the ring seat is installed at the bottom of the sleeve. Multiple connecting rods are hinged to the ring seat, and the other end of each connecting rod is hinged to a connecting seat corresponding to the wheel seat. A through hole is provided on the sleeve, and a pin for limiting the upward position of the ring seat can be selectively inserted into the through hole.

[0007] Furthermore, the upright frame includes a sleeve and three support legs fixed to the periphery of the sleeve, the bottom ends of the support legs being fixedly connected to the base frame by bolts.

[0008] Furthermore, the upper end of the sleeve is fitted inside the tube, and the limiting ring cooperates with the bottom end face of the tube to achieve limiting.

[0009] Furthermore, the deep groove and the corresponding rolling assembly and connecting rod are all in the form of three, and are evenly arranged along the circumference of the base frame.

[0010] Furthermore, when the ring seat slides to engage with the pin, the wheel seat is in a vertical position, causing the roller to protrude from the deep groove and contact the ground.

[0011] Furthermore, when the ring seat slides to engage with the limiting ring, the connecting rod pulls the wheel seat to rotate around its pin to a horizontal state and be housed in the deep groove, at which point the bottom of the deep groove is in contact with the ground.

[0012] Furthermore, the pin is one of a cotter pin, a latch pin, or a quick-release pin.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the rollers are completely retracted into the deep groove of the base frame, and the bracket is stably supported on the ground by the bottom surface of the entire base frame. The large contact area and low center of gravity greatly improve wind resistance and stability, and eliminate the safety hazard of easy swaying of the wheeled bracket.

[0015] 2. The retraction and extension function of this bracket relies on a purely mechanical structure, requiring no complex hydraulic, electrical, or gear systems. The entire operation can be completed simply by inserting or pulling out a single main pin, making it a simple and convenient action.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a mobile communication antenna fixing bracket, which aims to solve the problems of inconvenient movement and inability to balance stability and convenience of existing antenna brackets.

[0029] The support mainly includes a base frame 1, a vertical frame 2, a sleeve 8, and a foldable rolling assembly.

[0030] The base frame 1 is typically made of a circular or triangular metal plate, providing a stable foundation for the device. Three deep grooves 101 are evenly spaced along the circumference of the base frame 1. These grooves 101 are used to accommodate the rolling assembly in its retracted state.

[0031] The upright frame 2 is fixedly installed on the upper surface of the base frame 1 by bolts. The upright frame 2 consists of a vertically arranged sleeve 201 and three support legs 202 welded to the circumference of the sleeve 201. The three support legs 202 are evenly distributed radially, and their bottom ends are firmly connected to the base frame 1 by bolts, together forming a sturdy and stable support structure.

[0032] The sleeve 8 is a hollow tubular component, the upper part of which is inserted into and fixed inside the sleeve 201 of the support frame 2. The sleeve 8 is used to insert and fix the antenna body 10. In the middle of the sleeve 8, there is a limiting ring 801 that is integrally formed or welded. When the sleeve 8 is installed in place, the lower surface of the limiting ring 801 contacts and engages with the bottom end face of the sleeve 201 of the support frame 2, thereby limiting the axial position of the sleeve 8.

[0033] There are three sets of foldable rolling components, each corresponding to one of the three deep grooves 101. Each set of rolling components includes a wheel seat 3 and a roller 4. One end of the wheel seat 3 is hinged to the deep groove 101 by a pin, allowing the wheel seat 3 to rotate with the pin as the center. The roller 4 is mounted on the other end of the wheel seat 3 via an axle.

[0034] The wheel seat 3 includes an upper fixed block and a lower connecting seat. The lower connecting seat is provided with a column, and the lower connecting seat is snapped onto the upper fixed block through the column. The upper fixed block and the lower connecting seat can rotate relative to each other.

[0035] The upper fixing block is installed in the deep groove 101 by a pin, and the lower connecting seat is connected to a roller 4.

[0036] On the sleeve 8, below the limiting ring 801, there is a ring seat 6 that can slide up and down along the sleeve 8. The bottom end of the sleeve 8 is machined with external threads and a fastening nut 7 is screwed on. The fastening nut 7 is used to mechanically limit the sliding position of the ring seat 6 and prevent it from falling off the sleeve 8. On the ring seat 6, three connecting rods 5 are circumferentially hinged to each other by pins. The other end of each connecting rod 5 is hinged to the connecting seat 301 provided on the corresponding wheel seat 3. In this way, the vertical linear motion of the ring seat 6 can be synchronously converted into the rotational motion of the three wheel seats 3 through the three connecting rods 5.

[0037] Furthermore, a through hole is provided on the rod body of the sleeve 8, located between the limiting ring 801 and the fastening nut 7. A pin 9 can be selectively inserted into this through hole to limit and lock the upward position of the ring seat 6. The pin 9 is preferably a locking element that facilitates quick insertion and removal, such as a cotter pin, a bolt, or a quick-release pin.

[0038] The working principle and usage process of this utility model are as follows:

[0039] When it is necessary to move the antenna support:

[0040] The operator presses down on any of the connecting rods 5 or pushes down the ring seat 6 directly. The ring seat 6 slides downward along the sleeve 8 and, through the three connecting rods 5, pushes the three wheel seats 3 to rotate outward and downward around their hinge pins until the wheel seats 3 are in a vertical position. At this time, the rollers 4 protrude from the deep groove 101 of the base frame 1 and contact the ground. When the ring seat 6 slides down to below the through hole on the sleeve 8, the pin 9 is inserted into the through hole to lock the position of the ring seat 6. At this time, the entire bracket is supported by the three rollers 4 and can be easily dragged and moved, which is extremely convenient.

[0041] When a fixed antenna is required:

[0042] After moving the bracket to the predetermined position, pull out pin 9. Under the action of gravity, the ring seat 6 will slide down naturally, or the bracket can be slightly lifted to make the ring seat 6 slide down. The ring seat 6 slides down and pulls the wheel seat 3 upward and inward around the pin axis through the connecting rod 5, so that the wheel seat 3 and the roller 4 are retracted and completely accommodated in the deep groove 101. When the ring seat 6 slides down to the point where its top contacts the bottom surface of the limiting ring 801 on the sleeve 8, the movement stops. At this time, the wheel seat 3 tends to be horizontal and is completely retracted, and the bottom surface of the base frame 1 is in direct contact with the ground, providing a huge contact area and friction, ensuring the ultimate stability of the bracket in use and effectively resisting wind loads and disturbances.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
