Description

The present invention relates to the field of communication technologies, and in particular, to a communication machine rejection. Background technique

With the continuous development of wireless communication technologies, communication devices such as outdoor base stations have been widely used. However, among the existing communication devices such as outdoor base stations, some of the communication devices may fail to waterproof due to the machine storing the device, causing functional problems of the communication device, thereby affecting the service life of the communication device. It can be seen that the waterproof performance is an important issue to be considered in the design and manufacturing process of the outdoor communication device. In the research on the waterproof performance of the outdoor communication device, the waterproof performance of the door-to-door rejection device is the bottleneck of the waterproof performance of the outdoor communication device.

In the conventional communication machine with a door opening structure (hereinafter referred to as: the door-to-door communication machine rejection), the center frame is formed on the frame body which is connected to the two rejecting doors, and the center column divides the frame which is rejected into the body. In two parts, a waterproof rubber strip is arranged around each part, and the waterproof rubber strip of each part of the body is pressed after the door is closed, so that a more reliable waterproof performance can be achieved. However, the communication machine refuses to be installed due to the presence of the neutral column, and it is not convenient to carry out the installation, operation and maintenance of the communication device in the body, and the space utilization rate in the body is low. As people's integration requirements for communication equipment are getting higher and higher, the size requirements for communication machines are getting more and more demanding, and the door-to-door communication machine including the center column is obviously unable to meet the application requirements of people. There are two main types of waterproof solutions for the door-to-door communication machine without the center column:

The pair of door communication devices provided in the prior art are not shown in the figure la, and a waterproof rubber strip 11 is arranged on the square frame of the reject body, and a longitudinal waterproof rubber strip 12 is formed on the movable end of the right door. When the door is closed, the right door is closed and then the left door is closed, so that the two doors are pressed against the waterproof rubber strip 11 on the body and the left door is pressed against the longitudinal waterproof strip 12 on the right door. The water that prevents the machine from being rejected from entering the machine is rejected. However, in the prior art, when the door is closed, the overlap between the longitudinal waterproof strip 12 on the right reject door and the waterproof strip 11 on the reject body is compressed and deformed to create a slit 13 as shown in FIG. Rejecting the upper water pressure is as large as the day when heavy rain or heavy rain occurs, the water is easily infiltrated into the machine along the gap 13, thereby reducing the waterproof performance of the communication machine. The door-to-door communication device provided by the prior art 2 is rejected, and no waterproof rubber strip is provided on the body, but A waterproof strip is separately provided on each reject door. Specifically, the left door includes a left door body 21 and a longitudinal boundary water baffle 22 connected to the left door body 21. As shown in FIG. 2a, a left waterproof rubber strip is disposed at the boundary between the left door body 21 and the reject body 24. 23; A right waterproof strip 25 is placed at the junction of the right reject door and the reject body 24, as shown in Fig. 2b. When the door is closed, the left door is closed and the right door is closed, so that the left waterproof strip 23 of the left reject door and the right waterproof strip 25 of the right reject door are pressed against the reject body, and the right reject door is pressed. On the longitudinal boundary flap 22 of the left door. However, in the prior art, when the door is closed, the vertical boundary flap 22 of the left door is overlapped with the right door, as indicated by the arrow circle in FIG. 2c, and there is inevitably a gap due to limited processing precision. Therefore, when the machine refuses to have a large water pressure, such as heavy rain or heavy rain, the water is easily oozing into the machine along the gap, thereby reducing the waterproof performance of the communication machine. Summary of the invention

The embodiment of the invention provides a communication machine rejection, which is used for improving the waterproof performance of the communication machine. The embodiment of the invention provides a communication machine rejection, comprising:

Rejecting the body and the first reject door and the second reject door connected to the reject body and supporting the split;

The communication device as shown in FIG. 3 includes: a reject body 31, a first reject gate 32, and a second reject gate 33; wherein the first reject gate 32 and the second reject gate 33 are respectively connected to the reject body 31, and the first The reject gate 32 and the second reject gate 33 support the splitting, that is, the first reject gate 32 and the second reject gate 33 can be opened and closed in the same direction as the reject body 31.

The first waterproof rubber strip 34 is disposed at the joint of the first rejecting door 32 and the rejecting body 31, and the longitudinal water guiding groove 35 is fixed to the joint of the first rejecting door 32 and the second rejecting door 33.

A second waterproof rubber strip 36 is disposed on the second reject door 33 at the joint with the reject body 31 and the longitudinal water guide 35.

When the first rejecting door 32 and the second rejecting door 33 are in the closed state, the first waterproof strip 34 and the second waterproof strip 36 are at least partially overlapped; the top of the longitudinal water guiding groove 35 and the first waterproof strip 34 and The overlapping embossments of the second waterproof strip 36 are opposite to each other for guiding the water infiltrated through the overlapping squeezing to the bottom of the first reject door 32.

The water retaining member 37 is also fixed to the position opposite to the bottom of the longitudinal water guiding groove 35, and the water retaining member 37 is for blocking the water flowing out through the longitudinal water guiding groove 35 from entering the rejecting body 31.

When the communication device provided in this embodiment is rejected in use: the state of the two rejected doors that are rejected by the communication device is as shown in FIG. 4a; when the rejection door needs to be closed, the first rejection gate 32 is first closed, such as Figure 4b; after closing the first reject door 32, the second reject door 33 is closed, as shown in Figure 4c. It can be seen from FIG. 4a-4c that the communication device provided in this embodiment has a double-opening structure, and the centering column is not disposed on the frame body of the rejecting body 31 and the two rejecting doors, that is, the communication provided in this embodiment The machine refuses to have double doors and no center pillar structure. Since the communication device provided by the embodiment has the double-opening door and no neutral column structure, it is convenient for the relevant personnel to perform operations such as installation, operation and maintenance of the communication device in the body, which is beneficial to fully utilizing the space in the body, thereby facilitating the communication of the communication machine. Rejecting the need for miniaturization.

The waterproof mechanism of the communication machine rejection provided by the embodiment is described below with reference to the accompanying drawings.

The structure of the communication machine provided in this embodiment is rejected in the double reject door closed state as shown in FIG. 5. When the communication machine is refused to be in the closed state: the first rejecting door 32 presses the first waterproof strip 34 against the rejecting body 31; the second rejecting door 33 presses the second waterproof strip 36 simultaneously to the first rejecting door 32 and rejects the body 3 1 ; the second waterproof strip 36 and the first waterproof strip 34 are respectively superposed and pressed at a portion where the second rejecting door 33 and the first rejecting door 32 are fitted, and the overlapping pressing portion 38 is as shown in FIG. 5; The overlapping squeezing portion 38 is opposed to the top of the longitudinal water guiding groove 35 of the hollow structure fixed to the first rejecting door 32; the bottom of the longitudinal water guiding groove 35 abuts against the water retaining member 37 fixed to the bottom of the rejecting body 31.

The enlarged structure of the overlapping portion 38 of the second waterproof strip 36 and the first waterproof strip 34 is shown in Fig. 6. Due to the limitation of the process conditions, the first waterproof strip 34 and the second waterproof strip 36 are deformed by overlapping extrusion, and a slit 39 is formed at the overlapping pressing portion 38; the slit 39 can reduce the gap size by improving the preparation process. But it cannot be avoided. When the gap is small, due to the waterproof protection of the first waterproof strip 34 and the second waterproof strip 36, the water accumulated on the top of the communication machine does not normally penetrate into the body of the communication machine; however, for example, communication is used outdoors. In the scene where the machine refuses to rain or rain, the top of the communication machine rejects more water. At this time, the water raft may seep through the gap 39. The direction of the water flow is shown by the dotted arrow in Fig. 3, and the water infiltrated from the gap 39. In the longitudinal gutter 35 of the first reject door 32, the longitudinal gutter 35 conducts water to the bottom of the first reject door 32; due to the blockage of the water retaining member 37, the water flowing out through the longitudinal gutter 35 cannot enter the body. Within 31, it flows to the outside of the reject 31.

It can be seen that the communication machine with double-opening and no neutral column structure provided by the embodiment refuses, and the water-proof rubber strip is sealed and the water penetrated by the slit formed by the overlapping squeezing of the waterproof rubber strip is waterproof. The combination of the modes improves the waterproof performance of the communication machine.
