Description

Technical Field

[0001] The utility model relates to the technical field of serial port servers, in particular to a serial port server with a dustproof structure. Background Art

[0002] Serial device server is a device used to provide serial port to network function. It can convert RS-232 / 485 serial port into TCP / IP protocol network interface, realize bidirectional transparent transmission between RS-232 / 485 / 422 serial port and TCP / IP protocol network interface, or support MODBUS protocol bidirectional transmission, so that serial port device can immediately have TCP / IP network interface function, connect to the network for data communication, and extend the communication distance of serial port device.

[0003] In the prior art, a serial port server often has multiple connection ports, and these connection ports are often not all used at one time. Dust easily enters the unused ports, and the wiring ports that have entered dust will be affected by the dust when in use, resulting in reduced reliability and stability of data transmission. Therefore, in response to the above problems, we propose a new serial port server with a dust-proof structure. Utility Model Content

[0004] The utility model mainly provides a serial port server with a dustproof structure, which can prevent dust from entering the connection port when not in use, is easy to use, and can ensure the reliability and stability of data transmission.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a serial port server with a dustproof structure, comprising a server body, a wiring port is provided on the rear surface of the server body, a connecting frame is fixedly connected to the rear surface of the server body near the outer side of the wiring port, a plurality of slots are equidistantly provided on the top of the connecting frame, a dustproof plate is slidably provided between the inner surface walls of the slots, a wedge-shaped opening is provided on the rear surface of the dustproof plate, a plurality of mounting blocks are equidistantly fixedly connected to the top of the connecting frame, a sliding groove is provided on the front surface of the mounting block, and a wedge-shaped block is slidably provided between the inner surface walls of the sliding groove.

[0006] Compared with the prior art, the advantages and positive effects of the utility model are:

[0007] 1. In the utility model, the dust shield can be driven to move upward by pulling the pull rod upward in cooperation with the limit column. The first spring, the wedge block and the wedge-shaped mouth cooperate to fix the dust shield moved upward. The dust shield can be released by pulling the connecting rod backward to drive the wedge block to move backward. Then, the dust shield is automatically reset under the action of the second spring, thereby blocking the unused wiring ports, which can effectively prevent dust from entering. The overall structure is simple and easy to use, and effectively solves the problem that the wiring ports on the serial port server are prone to dust entering when not in use, resulting in reduced reliability and stability of data transmission.

[0008] 2. In the utility model, the limiting groove inside the sliding groove and the limiting block on the surface of the wedge block cooperate with each other to limit the moving stroke of the wedge block, so that when the first spring pushes the wedge block to move forward, only the bottom inclined surface of the wedge block will leak out of the sliding groove. The structure is simple, which effectively avoids the problem of the dustproof plate getting stuck when moving upward, and ensures its reliability during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] See also Figure 1-Figure 5 The utility model provides a technical solution: a serial port server with a dustproof structure, comprising a server body 1, a wiring port 11 is matched on the rear surface of the server body 1, a connection frame 2 is fixedly connected to the rear surface of the server body 1 near the outer side of the wiring port 11, a plurality of slots 22 are equidistantly provided on the top of the connection frame 2, a dustproof plate 53 is slidably provided between the inner surface walls of the slots 22, a wedge-shaped opening 54 is provided on the rear surface of the dustproof plate 53, a plurality of mounting blocks 3 are equidistantly fixedly connected to the top of the connection frame 2, a sliding groove 32 is provided on the front surface of the mounting block 3, and a wedge-shaped block 4 is slidably provided between the inner surface walls of the sliding groove 32.

[0017] like Figure 2-Figure 5 As shown, the wedge block 4 and the wedge-shaped mouth 54 cooperate with each other, the top of the dustproof plate 53 is symmetrically fixedly connected to the limiting column 51, and a pull rod 5 is fixedly connected between the tops of the two limiting columns 51. The wedge block 4 and the wedge-shaped mouth 54 cooperate with each other to fix the dustproof plate 53 in the set position, and the pull rod 5 cooperates with the limiting column 51 to facilitate the upward pulling of the dustproof plate 53, and the limiting column 51 has the function of limiting the dustproof plate 53, so that it can move up and down stably.

[0018] like Figure 1-Figure 5 As shown, a flange 31 is provided at the top of the mounting block 3 near the front side, and the outer surface of the limiting column 51 slides through the outer surface of the flange 31 and extends upward. The outside of the limiting column 51 is sleeved with a second spring 52 at a position below the flange 31. The second spring 52 is provided to squeeze the dustproof plate 53 downward, so that the dustproof plate 53 will automatically reset after losing the restriction.

[0019] like Figure 4 As shown, a first spring 41 is fixedly connected to the rear surface of the wedge block 4, and a rear end of the first spring 41 is connected to the rear inner surface wall of the sliding groove 32. The first spring 41 is provided to provide a forward thrust for the wedge block 4.

[0020] like Figure 2-Figure 5As shown, a movable groove 34 is provided on the top of the mounting block 3, and a connecting rod 42 is fixedly connected to the top of the wedge block 4. The outer surface of the connecting rod 42 passes through the movable groove 34 and extends upward. The movable groove 34 is provided on the top of the mounting block 3 mainly to avoid the connecting rod 42. By pulling the connecting rod 42 backward, the wedge block 4 can be driven to slide into the sliding groove 32, thereby separating from the wedge-shaped mouth 54, thereby achieving the purpose of releasing the dustproof plate 53 from being fixed.

[0021] like Figure 4 As shown, the inner bottom of the sliding groove 32 is symmetrically provided with a limiting groove 33, and the bottom of the wedge block 4 is fixedly connected to a limiting block 43 near the rear side. The position of the limiting block 43 and the limiting groove 33 match each other. The limiting groove 33 and the limiting block 43 match each other to limit the moving stroke of the wedge block 4 and prevent it from escaping from the sliding groove 32.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, a plurality of filling columns 21 are equidistantly and fixedly connected between the inner top and the inner bottom of the connecting frame 2, and the outer surface of the filling column 21 is in contact with the outer surface of the dustproof plate 53. The filling column 21 is provided to increase the firmness of the connecting frame 2 and to fill the gaps between the dustproof plates 53.

[0023] The method of use and working principle of this device are as follows: when some of the wiring ports 11 on the rear side of the server body 1 need to be used, the pull rod 5 is pulled upwards. At this time, the pull rod 5 cooperates with the limit column 51 to drive the corresponding dust cover 53 to move upwards. During the upward movement of the dust cover 53, it will squeeze the wedge block 4 from bottom to top and retract it into the interior of the sliding groove 32. When the dust cover 53 moves to a certain height, the wedge-shaped opening 54 on the rear side will correspond to the height of the wedge block 4. At this time, the squeezed and contracted first spring 41 will rebound and push the wedge block 4 to move forward and then enter the wedge-shaped opening 54, thereby fixing the dust cover 53, and then exposing the wiring port 11 that needs to be used for the user. At the same time, the connection rod 42 is pulled backwards to drive the wedge block 4 to move backward and then disengage it from the wedge opening 54 to release the dust cover. In addition to fixing the dustproof plate 53, the second spring 52 will rebound and push the dustproof plate 53 to move downward and then complete the reset, thereby blocking the unused wiring port 11, which can effectively prevent dust from entering. The overall structure is simple and easy to use. It effectively solves the problem that the wiring port 11 on the serial port server is prone to dust when not in use, resulting in a decrease in the reliability and stability of data transmission. In addition, the limiting groove 33 inside the sliding groove 32 and the limiting block 43 on the surface of the wedge block 4 cooperate to limit the moving stroke of the wedge block 4, so that when the first spring 41 pushes the wedge block 4 to move forward, only the bottom inclined surface of the wedge block 4 will leak out of the sliding groove 32. The structure is simple, which effectively avoids the problem of the dustproof plate 53 getting stuck when moving upward, and ensures reliability during use.
