Background

The antenna feeder is a feeder of an antenna, also called a feeder, and is an electromagnetic transmission line connecting the antenna and a transmitter and receiver, and an antenna feeder system is an important component of microwave relay communication. The antenna functions to convert an electromagnetic wave transmitted in a feeder line, which is a transmission path of the electromagnetic wave, into an electromagnetic wave propagated in a free space, or vice versa. In a microwave relay communication circuit of a multi-channel shared antenna feeder system, the technical performance and quality indexes of the antenna feeder system directly influence the communication quality of each microwave channel of the shared antenna feeder system. Therefore, the normal operation of the antenna feeder system can not only improve the coverage rate and reduce blind areas, but also reduce interference, crosstalk and the like and reduce the call drop rate.

However, the antenna feeder is installed in an outdoor environment, and is easily affected by human collision, rain, wind and other natural factors, so that the joint is loosened, water enters, corrosion and the like cause transmission loss to be increased, and the communication quality is seriously affected. At present, the joint protection method which is commonly used is to use waterproof daub and adhesive tape to wrap the joint layer by layer for sealing. However, the mode has high requirements on operators, wastes time and labor, has poor reliability, is disposable and can not be reused, and the maintenance cost is greatly increased.

Recently, some antenna feeder connector protection boxes exist in the market, but the antenna feeder connector protection boxes generally have many defects, such as: the installation and the disassembly are complicated, and the efficiency is not high; the fixed not good of internal joint's structure, closely knit effect is relatively poor. And the structure and the volume of the device are not properly designed, which brings difficulty to engineering installation. Meanwhile, the protection box needs to be kept in an open state in the process of installing the protection box after the feeder line is butted, and the single unimpeded turnover shell can cause inconvenience to installation.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1, which is a first embodiment of the present invention, as shown in fig. 1, this embodiment provides an overall structural schematic diagram of a reversible positioning type feeder line protection device, and as can be seen from the figure, the main structure of the present invention includes a housing main body 100, which is disposed at the periphery of the reversible positioning type feeder line protection device and includes a first housing 101 and a second housing 102; the first shell 101 and the second shell 102 are hinged at one side through a connecting piece L, the other side is locked through a sliding piece H after being closed and butted, and an accommodating space R is formed inside after being closed; and a seal member 200 provided inside the casing main body 100, having a first seal member 201 and a second seal member 202 corresponding to the first casing 101 and the second casing 102, the first seal member 201 having a branch F thereon and extending outside the first casing 101.

Specifically, in the present invention, the main structure of the reversible positioning feeder line protection device mainly includes a housing main body 100 and a sealing member 200. The housing main body 100, which has an external protection function in the present invention, is disposed at the periphery of the present invention, and mainly includes two components, i.e., a first housing 101 and a second housing 102. The overall structures of the first casing 101 and the second casing 102 are substantially the same, and are symmetrically arranged.

Further, the first casing 101 and the second casing 102 are both box-shaped in external structure and have a cavity inside, and are connected at one longitudinal side edge by a connecting piece L. In this embodiment, the connecting element L may be a hinge, so that the first housing 101 and the second housing 102 are connected in a hinged manner, and both can be turned around the connecting element L. After the first housing 101 and the second housing 102 are closed, the other side edge of the connecting member L is locked by the slider H, and the first housing 101 and the second housing 102 are completely locked. The slider H is in the form of a slider for connecting and snapping the first housing 101 and the second housing 102, and is disposed on the other side edge of the second housing 102 with respect to the connecting piece L.

Further, after the first housing 101 and the second housing 102 are closed, an accommodating space R is formed inside for accommodating two connectors of the antenna feeder connected. Further, after the first casing 101 and the second casing 102 are closed, a wire inlet X-1 and a wire outlet X-2 are formed at both longitudinal ends of the integrated device. The inlet X-1 and the outlet X-2 are respectively used as the leading-in channel and the leading-out channel of the antenna feeder. Preferably, vertical ribs 103 are disposed on the outer sides of the first casing 101 and the second casing 102, and the vertical ribs are vertically crossed in two directions, so as to improve the stress performance and the structural stability of the entire shell body 100.

The sealing member 200 has a function of filling the gap, compacting the antenna feeder terminal placed in the receiving space R, and keeping it firm to prevent loosening.

The seal member 200 is provided inside the housing main body 100, and the seal member 200 also has a first seal member 201 and a second seal member 202 corresponding to the first housing 101 and the second housing 102 which are symmetrically provided. The first seal 201 and the second seal 202 have the same structural form and are symmetrical structures. The first sealing member 201 is embedded in the first housing 101, and the second sealing member 202 is embedded in the second housing 102.

Further, the body shape of the sealing member 200 is fitted to a circumferential contour of the inside of the housing body 100, and in particular, it is disposed and embedded on the inner sidewall of the housing body 100.

Further, the main body of the sealing member 200 has a branch F, and the branch F of the first sealing member 201 extends out and extends to the outside of the first casing 101.

Referring to fig. 2 to 6, a second embodiment of the present invention is different from the first embodiment in that: a first edge piece B-1 extends outwards from one side edge of the first shell 101 corresponding to the sliding piece H, and a first slide way D-1 is arranged on the first edge piece B-1.

In this embodiment, the main structure of the present invention includes a housing main body 100. The housing main body 100 is disposed at the periphery of the present invention, and mainly includes two constituent parts, a first case 101 and a second case 102. The overall structures of the first casing 101 and the second casing 102 are substantially the same, and are symmetrically arranged.

Further, the first casing 101 and the second casing 102 are both box-shaped in external structure and have a cavity inside, and are connected at one longitudinal side edge by a connecting piece L. The first housing 101 and the second housing 102 are connected in a hinged manner, and both can be reasonably turned around the connecting piece L. After the first housing 101 and the second housing 102 are closed, the other side edge of the connecting member L is locked by the slider H, and the first housing 101 and the second housing 102 are completely locked.

In the present invention, a first edge member B-1 extends outward from an edge of the first housing 101 corresponding to one side of the sliding member H. The first edge member B-1 is formed in a strip shape as a whole, and is disposed along the longitudinal direction of the first housing 101. The first edge member B-1 is cantilevered outwardly with a certain width perpendicular to the first housing 101.

Furthermore, a first slide way D-1 is arranged at the outer edge position of the first edge piece B-1, and the first slide way D-1 is long and is arranged on the outer surface of the first edge piece B-1. And a chute C is arranged on the first slideway D-1 and is used for providing a track path for the sliding of the sliding piece H. The chute C is groove-shaped and extends in the longitudinal direction of the first ramp D-1.

Furthermore, a partition block G is arranged in the middle of the first slide way D-1, and the first slide way D-1 is divided into two sections of symmetrical slide ways by the partition block G. Specifically, the upper surface of the partition block G is flush with the upper surface of the main body of the first slideway D-1, and therefore, the upper surface of the partition block G is higher than the bottom of the chute C. It is apparent that the sliding member H is prevented from stopping when it slides in the slide groove C and encounters the stopper G. In this embodiment, the first slideway D-1 is further provided with a pair of grooves a symmetrical with respect to the block G. Because the first slideway D-1 is divided into two sections by the partition block G, the first slideway D-1 of the left section and the right section is provided with a groove A and is arranged symmetrically. The groove A cuts off the first slideway D-1, and the bottom plane of the groove A is flush with the outer side surface of the first edge piece B-1.

It should be noted that: the length of the first slideway D-1 is less than the total length of the first casing 101 in the present invention. Since the first slideway D-1 has a symmetrical structure, both ends of the first slideway D-1 do not extend to the positions of both ends of the first casing 101, there is a gap at both ends of the first slideway D-1.

Furthermore, two symmetrical through holes K are formed in the first edge piece B-1, a pressing piece 300 is fixed inside each through hole K, the outer end of each pressing piece 300 is fixed in each through hole K, and the inner end of each pressing piece freely rotates; the outer edge of the pressing member 300 is extended with a second slideway D-2, and the size of the second slideway D-2 is matched with the size of the groove A on the first slideway D-1, and meanwhile, a chute C is also arranged on the second slideway D-2. Specifically, the through hole K is elongated and has two symmetrical through holes, which are located at the inner side of the first slideway D-1. The pressing member 300 is an elongated member having a size slightly smaller than the size of the through hole K. The pressing member 300 has an outer end fixed to the outer end of the through hole K and the other end being a free end, so that the pressing member 300 can rotate around the fixed end of the outer end. The outer edge of the pressing member 300 is further provided with a second slideway D-2 which extends outwards, and the size of the second slideway D-2 is complementary to that of the groove A on the first slideway D-1 and can be matched and connected with each other, so that when the pressing member 300 rotates to be parallel to the surface of the first edge member B-1, the second slideway D-2 on the pressing member can be just embedded into the groove A, the first slideway D-1 and the second slideway D-2 can be in seamless butt joint to form a whole, and the chutes C of the first slideway D-1 and the second slideway D-2 can also be communicated.

In the present invention, a second edge member B-2 extends from one side edge of the second housing 102 corresponding to the sliding member H; one surface of the second edge piece B-2 corresponding to the first slideway D-1 is provided with a third slideway D-3, after the first shell 101 and the second shell 102 are covered, the third slideway D-3 and the first slideway D-1 are mutually complementary to form a butt joint, and the total length of the slideways after the butt joint is equal to the length of the first shell 101. Specifically, a second edge member B-2 extends outward from the edge of the second housing 102 corresponding to one side of the sliding member H. The second edge member B-2 has the same structure as the first edge member B-1, has a strip-like shape, and is disposed along the longitudinal direction of the second housing 102. The second edge member B-2 is cantilevered perpendicularly to the second housing 102 by a width that is the same as the width of the first edge member B-1.

As can be seen from the above, the length of the first slideway D-1 is less than the total length of the first casing 101, and both ends of the first slideway D-1 do not extend to the positions of both ends of the first casing 101, so that there is a gap at both ends of the first slideway D-1. And the third slideway D-3 is just arranged at the vacancy corresponding to the two ends of the first slideway D-1 on the second edge piece B-2, and after the first shell 101 and the second shell 102 are butted, the chute C on the third slideway D-3 is communicated with the chute C on the second slideway D-2 and the first slideway D-1 to jointly form all slideways on the side of the first shell 101.

Further, a fourth slide way D-4 is arranged on the other surface of the second edge piece B-2 corresponding to the third slide way D-3; the length of the fourth slideway D-4 is equal to the length of the second housing 102. Specifically, the fourth slideway D-4 is a coherent integral slideway, is arranged on the opposite surface of the third slideway D-3, and is also provided with a chute C with the same specification.

Further, the sliding part H is integrally of a groove-shaped structure and is divided into a side plate H-1, a bottom plate H-2 and a convex rib H-3. The side plates H-1 are positioned at two sides of the bottom plate H-2 and are connected to form a groove shape, and the convex ribs H-3 are arranged at the inner sides of the two side plates H-1 and are in the same shape as the sliding groove C. When the sliding piece H is used, the opening is just opposite to the first edge piece B-1 and the second edge piece B-2 to be embedded, and the convex edge H-3 is correspondingly clamped in the sliding groove C to realize sliding in the sliding groove C.

In the present invention, after the first casing 101 and the second casing 102 are closed to each other, the inner surfaces of the first edge member B-1 and the second edge member B-2 are attached to each other, and at this time, the third slide way D-3 is communicated with the first slide way D-1. The pressing member 300 is rotated such that the second runner D-2 thereof is fitted into the groove a of the first runner D-1, and thus the first runner D-1, the second runner D-2 and the third runner D-3 are integrally communicated and located at one side. Meanwhile, the fourth slide way D-4 is positioned on the other side surface, and the sliding piece H slides in the communicated slide groove C. When the slide block H slides to the position of the second slideway D-2, the press piece 300 cannot be loosened because the slide block H blocks the second slideway D-2, and simultaneously the first slideway D-1 and the fourth slideway D-4 are clamped, so that the whole device is in a locking state. If the sliding member H slides to the third slide way D-3 towards both sides, the first edge member B-1 and the second edge member B-2 can be separated and in a loose state because the first slide way D-1 and the fourth slide way D-4 are not clamped simultaneously.

Referring to fig. 7 to 10, a third embodiment of the present invention is different from the second embodiment in that: the first shell 101 and the second shell 102 are provided with symmetric caulking grooves Q inside, and the sealing element 200 is embedded in the caulking grooves Q; the branch F of the first sealing member 201 passes through the outside of the first housing 101 through the through hole K and is located directly below the pressing member 300.

In the present invention, the sealing member 200 has a function of filling the gap, compacting the antenna feeder terminal placed in the receiving space R, and keeping it firm to prevent loosening.

In the present embodiment, the inner side walls of the first and

second housings

101 and 102 are each provided with a caulking groove Q, the caulking grooves Q on both sides are symmetrical to each other, and the first and

second sealing members

201 and 202 are each embedded in the caulking groove Q. The overall shape of the caulking groove Q is fitted to the main body portion of the seal member 200.

In the present invention, two branches F extend from the main body of the sealing member 200, and two symmetrical through holes K are formed in the first edge member B-1, and the through holes K communicate with the insertion groove Q inside the first housing 101 and connect the inside and outside of the first housing 101. Specifically, the main body of the first seal member 201 is disposed in the insertion groove Q, and the branch F thereof extends out of the outer side of the first housing 101 right through the through hole K. As described above, since the pressing member 300 is further disposed in the through hole K, when the whole device is closed and locked, the pressing member 300 just covers the branch F to press the branch F, so that the gas in the branch F is squeezed into the main body of the sealing member 200, and the main body of the sealing member 200 is expanded to increase the volume. The expanded sealing member 200 generates larger extrusion force and contact area to the antenna feeder joint placed in the device, so that the antenna feeder joint also obtains better sealing effect, the structure is fastened and reliable, and the interface is prevented from loosening.

Preferably, in this embodiment, the surface of the pressing member 300 contacting the sealing element 200 may be serrated to reduce the frictional resistance when the pressing member 300 is pressed down.

Referring to fig. 11, a fourth embodiment of the present invention is different from the third embodiment in that: the outer side surface of the connecting piece L is provided with a protruding piece T, and the outer side surface of the third slide way D-3 is provided with a hole N corresponding to the protruding piece T; after the housing body 100 is fastened, the protruding member T is inserted into the hole N of another identical device to form a parallel connection of multiple sets of devices.

As can be seen from the above, the first casing 101 and the second casing 102 are connected at one side by the connecting piece L in a hinged manner, i.e., by using a hinge. Specifically, the edges of the connecting sides of the first casing 101 and the second casing 102 are respectively provided with a plurality of protrusions, a round hole is formed in the center position, when the two casings are butted, the protrusions can be mutually matched and inserted, all the round holes can be communicated in a straight line direction, and a bolt is used for penetrating through all the round holes to complete the connection of the first casing 101 and the second casing 102. Among the projections connected by the connecting member L, the first housing 101 and the second housing 102 each have a projection T longer than the other projections, so that each connecting member L has two adjacent projections T. When the first housing 101 and the second housing 102 are fastened together, the ends of two adjacent protruding members T are exactly overlapped with each other to form an assembly.

Meanwhile, holes N are formed in the outer side surfaces of the outer edges of the fasteners, which are supplemented to the two ends of the second housing 102, and the shapes and positions of the holes N correspond to the sizes of the protruding members T. The holes N are two and are distributed in bilateral symmetry. When the housing body 100 of one device of the invention is closed, the protruding pieces T on the outer side of the connecting piece L form a combined whole, the protruding pieces T of one device are inserted into the holes N of another same device, and the two devices can be connected in parallel, and can be connected in parallel indefinitely according to the mode.

Referring to fig. 8 or 12 to 16, a fifth embodiment of the present invention is different from the first embodiment in that: the main structure of the present invention further includes a damping member 400 disposed at the outer end of the connecting member L and cooperating with the connecting member L to form a whole.

The damping assembly 400 has a function of both hinge and positioning, and includes an elastic damping block 401, a wear-resistant block 402, a rotating shaft 403 and an adjusting member 404, wherein the rotating shaft 403 penetrates through the connecting member L and hinges the first housing 101 and the second housing 102. In this embodiment, the elastic damping block 401 is a protrusion as described in the fourth embodiment, and the rotating shaft 403 is a latch as described in the fourth embodiment.

Further, the rotating shaft 403 is fixed at the position of the corresponding connecting piece L of the second housing 102, as shown in fig. 8. The shaft 403 has a cylindrical shape with a length of thread on its outer surface. Further, the outer side surface of the rotating shaft 403 is further provided with two first grooves 403a and two second grooves 403b which are parallel to each other, the first grooves 403a and the second grooves 403b are groove-shaped and arranged along the longitudinal direction of the rotating shaft 403, and the two grooves are opposite to each other on the outer side surface of the rotating shaft 403.

In this embodiment, the wear-resistant block 402 is sleeved on the periphery of the rotating shaft 403. The main body of the wear-resistant block 402 is in a sleeve shape, the interior of the wear-resistant block is a hollow channel, and the inner diameter of the wear-resistant block corresponds to the outer diameter of the main body of the rotating shaft 403. Further, the inner side wall of the wear-resistant block 402 is provided with a first projection 402a and a second projection 402b corresponding to the first recess 403a and the second recess 403 b. The first bump 402a and the second bump 402b are matched in size and structure with the first groove 403a and the second groove 403b, respectively, and are complementary. When the wear-resistant block 402 needs to be sleeved outside the rotating shaft 403, the first protrusion 402a and the second protrusion 402b are only required to be aligned with the first groove 403a and the second groove 403b respectively, and the nesting can be realized by pushing.

In this embodiment, the wear-resistant blocks 402 are mounted on the elastic damping blocks 401. The elastic damping block 401 is fixed to the side of the first housing 101, and has an opening in the longitudinal direction of the first housing 101, the size of the opening corresponding to the outer diameter of the main body of the wear-resistant block 402. Further, a plurality of damping protrusions 401a are arranged on the inner side wall of the elastic damping block 401, and the damping protrusions 401a are strip-shaped protrusions which are arranged at equal intervals along the longitudinal direction of the elastic damping block 401. Correspondingly, the outer side surface of the wear-resistant block 402 is provided with a first damping strip 402c and a second damping strip 402d, the first damping strip 402c and the second damping strip 402d are strip-shaped high-strength wear-resistant protrusions, and the first damping strip 402c and the second damping strip 402d are oppositely arranged on the outer side surface of the wear-resistant block 402 along the longitudinal direction of the wear-resistant block 402. The widths of the first damping strip 402c and the second damping strip 402d are smaller than the distance between any two adjacent damping protrusions 401a, so that when the wear-resistant block 402 is inserted into the opening of the elastic damping block 401, the first damping strip 402c and the second damping strip 402d can be inserted into the gap between the damping protrusions 401 a. When the first housing 101 integrally surrounds the rotating shaft 403 and drives the wear-resistant block 402 to rotate, the first damping strips 402c and the second damping strips 402d on the wear-resistant block 402 are in a discontinuous interval motion state due to the blocking effect of the densely arranged damping protrusions 401a, and the resistance effect is always existed in the rotating process.

Preferably, the ends of the damping protrusions 401a are provided in a tooth shape to optimize the resistance effect.

In practical use, since the rotating shaft 403 is fixed at the position corresponding to the connecting member L on the second casing 102, the rotating shaft 403 is kept stationary with respect to the second casing 102 when the first casing 101 is turned over. At this time, the rotation center axis of the first casing 101 is the center axis of the rotation shaft 403. Since the first projection 402a and the second projection 402b of the wear-resistant block 402 are inserted and matched with the first recess 403a and the second recess 403b of the rotating shaft 403 to form a fixed connection, the wear-resistant block 402 is also kept fixed relative to the second housing 102. On the other hand, although the elastic damping block 401 is sleeved on the periphery of the wear-resistant block 402, it is also fixed on the side of the first casing 101, so that the elastic damping block 401 rotates along with the first casing 101. Obviously, the first damping strip 402c and the second damping strip 402d on the outer side surface of the wear-resistant block 402 will generate a spacing blocking effect on the damping protrusion 401a on the inner side wall of the elastic damping block 401, that is, a spacing blocking effect on the overturning of the first shell 101 is realized.

The damping assembly 400 can enable the first shell 101 to have a certain buffering effect when the first shell is opened and closed, and meanwhile, the first shell 101 can be opened to any angle and kept fixed, and has a certain positioning effect, so that the installation operation is facilitated.

Preferably, the inner end surface of the wear-resistant block 402 is contacted with the end surface of the protruding member T at the rear end thereof by a compression spring and is compressed. In this embodiment, the threaded section at the upper end of the rotating shaft 403 is further sleeved with an adjusting member 404, and the adjusting member 404 is a nut which is always attached to the outer end surface of the wear-resistant block 402 during use. Therefore, the wear-resistant block 402 can be extruded by rotating the adjusting member 404 to be stretched along the longitudinal direction of the rotating shaft 403, so as to adjust the connection length between the damping protrusion 401a and the first damping strip 402c and the second damping strip 402d, and finally achieve the effect of controlling and adjusting the damping effect.
