[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The following is combined with Figures 1-7 This utility model describes a connection port protection structure based on a handheld terminal, including a front shell 300, a rear shell 200, and a protection structure 400.

[0035] A notch 201 is provided on the bottom side wall of the rear shell 200;

[0036] The front shell 300 is located at the front of the rear shell 200. The front shell 300 has a mounting block 301 on one side of the corresponding notch. The mounting block 301 is located inside the notch 201 and has a first through groove 302.

[0037] The front shell 300 and the rear shell 200 constitute the handheld terminal housing 100, and the handheld terminal housing 100 is provided with a wiring port 101 inside.

[0038] Furthermore, a first mounting groove 303 is recessed on the outer surface of the mounting block 301, and the first mounting groove 303 communicates with the interior of the handheld terminal housing 100 through a first through groove 302.

[0039] The protection structure 400 comprises a protection block 401, a second through slot 403 and a reciprocating blocking mechanism 500, the protection block 401 is arranged in the first mounting slot 303, a second mounting slot 404 is arranged on one side of the protection block 401 facing the first through slot 302, the second mounting slot 404 is communicated with the outside through the second through slot 403, and the reciprocating blocking mechanism 500 is located in the second mounting slot 404.

[0040] The reciprocating blocking mechanism 500 comprises two movable blocks 402 arranged symmetrically, one end of each of the two movable blocks 402, which faces away from each other, is connected to the inner wall of the second mounting slot 404 through a compression spring 405, and the two ends of the two movable blocks 402, which face each other, abut against each other.

[0041] In the embodiment, as shown in the figure, Figure 1 The left and right ends of the first mounting slot 303 are each provided with a threaded hole, and the protection block 401 is provided with a through hole corresponding to the threaded hole, a screw is screwed into the threaded hole through the through hole, the protection structure 400 can be fixed in the first mounting slot 303, which is conducive to protecting the wiring port 101, and the protection structure 400 will not easily fall off.

[0042] One end of each of the two movable blocks 402, which faces away from each other, is provided with a spring connecting groove 406, one end of the compression spring 405 is located in the spring connecting groove 406, and the inner wall of the second mounting slot 404 on the opposite sides is respectively provided with a spring connecting column 407, one end of the compression spring 405, which is away from the spring connecting groove 406, is sleeved on the spring connecting column 407, and the spring connecting groove 406 and the spring connecting column 407 ensure the stability and reliability of the compression spring 405, and provide stable support for the reciprocating movement of the movable block 402.

[0043] One side of the movable block 402 facing the second through slot 403 is inclined, the inclined surface is inclined from one side close to the compression spring 405 to the other side towards the first through slot 302, when the terminal head 600 extrudes the reciprocating blocking mechanism 500 from one side of the second through slot 403 towards the first through slot 302, the reciprocating blocking mechanism 500 is displaced, so that the terminal head 600 can be inserted into the wiring port 101. When the terminal head 600 extrudes one side of the movable block 402, which is inclined, the inclined surface is conducive to extruding the movable block 402 to the two sides by the terminal head 600 and directly entering the wiring port 101, so that the process of inserting the terminal head 600 into the wiring port 101 is more simple and convenient.

[0044] Further, in specific embodiments, the reciprocating blocking mechanism 500 is used to move the movable block 402 away from the end of the second through slot 403 under the extrusion of the terminal 600 when the terminal 600 is inserted into the terminal port 101, so that the terminal 600 is smoothly inserted into the terminal port 101, and at the same time, the compression spring 405 gradually overcomes the spring resistance and is continuously compressed, increasing the spring force. The spring force of the compression spring 405 ensures that the terminal 600 is not easily loosened and falls off when connected with the terminal port 101. When the terminal 600 is pulled out of the terminal port 101, the spring force of the compression spring 405 is released, so that the two movable blocks 402 return to the original position and abut against each other in front of the terminal port 101.

[0045] In the embodiment, as Figures 6-7 When the terminal 600 is not inserted into the terminal port 101, the protection structure 400 is in a closed state, the reciprocating blocking mechanism 500 is in the middle of the first through slot 302 and the second through slot 403, and the two movable blocks 402 abut against each other in front of the terminal port 101 under the action of the spring force of the compression spring 405, so that the user protects the terminal port 101 and prevents foreign matter from entering.

[0046] When the terminal 600 is to be inserted into the terminal port 101, the terminal 600 will continuously extrude the two movable blocks 402 away from the second through slot 403 during the movement from the second through slot 403 to the first through slot 302. The movable block 402 gradually moves away from the second through slot 403, and in the extrusion process, the compression spring 405 is gradually compressed, and the spring force is continuously increased until the terminal 600 is inserted into the terminal port 101. At the same time, the terminal 600 will also be subjected to the accumulated spring force of the compression spring 405 from both ends, so that the terminal 600 is stably connected with the terminal port 101 and cannot be easily loosened and fallen off.

[0047] When the terminal 600 is pulled out of the terminal port 101, at the moment of pulling out, the two movable blocks 402 lose the blocking near the end of the second through slot, and the accumulated spring force of the compression spring 405 at both ends of the second mounting slot 404 is released and pushes the two movable blocks 402 to move away from the second through slot 403 until the two movable blocks 402 abut against each other in front of the terminal port 101, continuing to protect the terminal port.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features. The modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
