Description

TECHNICAL FIELD

[0001] The utility model relates to a combiner technology field, concretely is a waterproof structure of 5G room distribution combiner. BACKGROUND

[0002] In recent years, in mobile communication, due to the sharing of multiple channels, in order to avoid the intermodulation interference caused by the radio frequency coupling between different channels, and considering the factors of economy, technology and erection site, the signal transmission usually uses a combiner, through which several radio frequency signals from different transmitters can be combined into one to be transmitted to the antenna, and the combiner is usually installed on the outdoor unit of digital microwave communication and is connected with the antenna port, and the combiner installed in the open air is easy to be entered into the combiner through the gap between the combiner housings, which affects the normal use of the combiner.

[0003] At present, the combiner used in the field of mobile communication generally includes a combiner housing and a sealing cover plate matched with the combiner housing, and a sealing ring is laid at the connection between the sealing cover plate and the combiner housing to realize the waterproof effect of the combiner. In actual production, in order to ensure the normal heat dissipation effect of the combiner, the combiner housing and the cover plate are usually made of heat-conducting metal materials. In extremely cold or hot weather, the sealing ring made of rubber or silicone expands and shrinks with heat, which can easily cause the sealing ring to be extruded or shrinkage deformation, resulting in a gap between the sealing cover plate and the combiner housing, greatly reducing the waterproof effect and shortening the service life of the combiner.

[0004] Under the prior art, the patent with publication number CN219874002U proposes a waterproof structure of a combiner, which includes a main unit including a combiner housing and a sealing cover plate matched with the combiner housing, and a waterproof sealing unit including an upper sealing ring fixedly installed on the lower side wall of the sealing cover plate and a lower sealing ring installed on the inner wall of the combiner housing, the upper sealing ring and the lower sealing ring are opposite in position, and a temperature sensing cylinder is fixedly installed on the inner wall of the upper end of each mounting groove.

[0005] The above device uses mercury to drive the sealing ring to move, and mercury is a kind of toxic heavy metal. In the use process of the combiner, if the temperature sensing cylinder is broken, the mercury will leak out, which will cause serious harm to the environment and human health. For example, the mercury vapor formed after the evaporation of mercury can enter the human body through the respiratory tract, damage the nervous system and other organs of the human body, and in the production, transportation, installation and maintenance process of the equipment, special attention should be paid to prevent the leakage of mercury, which increases the additional safety risk control cost and operation difficulty, therefore, we propose a waterproof structure of a 5G room distribution combiner to solve the above problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at solving one of the technical problems existing in prior art or related art.

[0007] To this end, the utility model adopts the technical scheme that:

[0008] A waterproof structure of 5G room distribution combiner, including box, the box top is provided with the closed cover, the closed cover bottom is fixedly connected with upper seal ring, the box top around is equipped with assembly slot, the assembly slot is built-in with lower seal ring, the box inner chamber is installed with control assembly, the control assembly includes installation chamber, the installation chamber is equipped in the box inner chamber bottom, the installation chamber is built-in with helium bag, the helium bag around is fixedly connected with a plurality of air pipes, the air pipe is built-in with movement seat one end close to lower seal ring, the movement seat bottom is fixedly connected with the top rod, the top rod bottom is fixedly connected with the lower seat, the lower seal ring bottom is equipped with a plurality of fixed grooves, the fixed groove is built-in with telescopic spring, the telescopic spring is connected with the connecting barrel one end away from lower seal ring, the connecting barrel bottom is fixedly connected with the assembly slot inner chamber bottom.

[0009] Preferably, the lower seal ring is slidably connected with the assembly slot wall, and the movement seat is slidably connected with the air pipe inner wall.

[0010] Preferably, the air pipe is in communication with the helium bag, and one end of the air pipe away from the helium bag extends through the box to the top of the lower seal ring.

[0011] Preferably, the movement seat is provided with a fixed ring groove around, and the fixed ring groove is sleeved with a gasket.

[0012] Preferably, one end of the top rod away from the movement seat extends through the air pipe to the top of the lower seal ring.

[0013] Preferably, the lower seat bottom is in contact with the lower seal ring, and the plurality of air pipes are uniformly distributed around the box axis.

[0014] Preferably, the gasket inner ring wall is in contact with the fixed ring groove inner cavity bottom, and the gasket outer ring wall is in contact with the air pipe inner wall and is slidably connected therewith.

[0015] Preferably, the plurality of fixed grooves are uniformly arranged along the width direction of the lower seal ring, one end of the telescopic spring is in contact with the fixed groove inner cavity bottom, and the other end of the telescopic spring is in contact with the connecting barrel inner cavity bottom.

[0016] By adopting the above technical scheme, the utility model has the beneficial effects that:

[0017] The waterproof structure in the utility model mainly comprises a box, a closed cover, an upper seal ring, a lower seal ring and a unique control assembly. The closed cover at the top of the box is sealed from the box through the upper and lower seal rings to protect the control assembly in the inner chamber of the box.

[0018] The key of the control assembly is that the helium bag is installed in the cavity at the bottom of the inner cavity of the box. The gas pipes connected around the helium bag are evenly distributed around the axis of the box and extend to the top of the lower sealing ring. The gas pipes have a moving seat slidingly connected with the inner wall, the moving seat is connected with the lower pressing seat through a top rod, and the lower pressing seat acts on the lower sealing ring. At the same time, the bottom of the lower sealing ring is connected with the connecting cylinder fixed at the bottom of the assembly groove by means of the telescopic spring.

[0019] The working principle is based on the cooperation of helium thermal expansion and contraction and spring elasticity. When the ambient temperature rises, the helium in the helium bag expands, pushes the moving seat upward along the gas pipe, makes the lower pressing seat press the lower sealing ring downward through the top rod, overcomes the spring elasticity to make the lower sealing ring move downward, avoids excessive expansion of the box and the sealing ring at high temperature to cause extrusion deformation, and still maintains a certain sealing to prevent water from entering. When the temperature decreases, the helium contracts, the spring elongates to drive the connecting cylinder to move upward, so that the lower sealing ring is in close contact with the upper sealing ring to ensure sealing.

[0020] This structure has obvious advantages. Firstly, it has strong temperature adaptability and can automatically adjust the position and sealing state of the sealing ring in high and low temperature environments to stabilize and prevent water. Secondly, it is safe, helium is inert, non-toxic and non-polluting, and is safer than mercury and other expansion media, and is suitable for indoor places where people move frequently. Thirdly, the cost is low, helium reserves are abundant and the cost is low, the structure design is simple, common parts and helium bags are used to realize the function, and the manufacturing cost and maintenance cost are reduced. Fourthly, the reliability and durability are good, the passive temperature self-adaptive mechanism has no complex driving components, reduces the risk of failure, ensures long-term stable operation, reduces downtime, is conducive to stable operation of the 5G communication network, and has great application value and development potential in the waterproof of the 5G indoor distribution combiner.
