[0027] To make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Referring to Figures 1 to 3 , the present utility model provides an optical fiber port safety lock, including: a frame body (10),

[0031] Another side surface of the frame body (10) is provided with a keyhole (12) and a guide hole (13);

[0032] On one side surface of the frame body (10) opposite to the keyhole (12), and at a position corresponding to the keyhole (12), a top block (14) is provided;

[0033] The top block (14) is elastically connected to the frame body (10);

[0034] One end of the top block (14) facing the keyhole is further provided with a slope (15);

[0035] On one side surface of the frame body (10) opposite to the slope (15), a clamping portion (11) and a top block hole (16) corresponding to the top block are fixedly provided.

[0036] The present utility model also provides an optical fiber port safety lock key, including: a holding portion (20), an insertion portion (21), and a positioning post (22);

[0037] Wherein the insertion portion (21) is arranged at one end of the holding portion (20), and the cross-sectional shape of the insertion portion (21) corresponds to the shape of the keyhole (12) on the optical fiber port safety lock;

[0038] The positioning post (22) cooperates with the guide hole (13) on the optical fiber port safety lock.

[0039] In this application, the shape of the housing (10) corresponds to the shape of the existing optical fiber port, and is used to close the existing optical fiber port after the housing (10) is inserted into the existing optical fiber port.

[0040] Among them, the shape of the clamping portion (11) on the housing (10) also corresponds to the shape of the notch on the elastic piece provided on the existing optical fiber port, and is used to be clamped with the elastic piece after the housing (10) is inserted into the optical fiber port, so as to clamp the housing (10) on the optical fiber port and prevent it from falling off easily.

[0041] The keyhole (12) corresponds to the position of the top block (14). After the housing (10) has been clamped on the optical fiber port, if you want to take out the housing (10), you need to use a key to open it.

[0042] The specific principle is that when the key is inserted, the insertion portion (21) of the key contacts the slope (15) on the top block (14). As the key is continuously inserted, since the top block (14) is elastically connected to the housing (10), the key will lift the top block (14). At this time, the top block (14) will move outwards from the housing and pass through the top block hole (16) on the housing. When the top of the top block (14) exceeds the housing (14), it will lift the elastic piece in the clamped state on the optical fiber port, so that the elastic piece is disengaged from the clamping portion (11), and thus the housing (10) can be taken out.

[0043] As a preferred embodiment, the keyholes (12) can be set to 2 and arranged symmetrically, and their shapes can be non-axisymmetric. Setting them to 2 can make the force on the top block (14) more uniform when lifting the elastic piece. The shape of the keyhole (12) is set to be non-axisymmetric, which is an anti-fooling design to avoid possible damage caused by reverse insertion of the key.

[0044] As another preferred embodiment, the inclination angle of the slope (15) on the top block (14) can be set to 20-40 degrees. Within this angle range, it can ensure that the key can smoothly lift the top block (14) when inserted, and it is not easy to cause jamming problems, nor will there be a problem of insufficient lifting height of the top block (14).

[0045] As another preferred embodiment, the guide hole (13) can be set between the two keyholes (12) for the insertion of the positioning post (21) provided on the key. The setting of the guide hole (13) and the positioning post (21) can guide the key to be inserted smoothly and avoid damage caused by the key being inserted obliquely.

[0046] As another preferred embodiment, anti-slip protrusions (23) can be provided on the holding portion (21) to reduce the possible slipping when holding the key.

[0047] As another preferred embodiment, a lanyard hole (24) is also provided on the holding portion (21) to facilitate carrying.

[0048] As another preferred embodiment, an indicating identification protrusion (25) is further provided on one surface of the holding portion (21) for indicating the front of the key and preventing damage that may be caused by inserting the key in the wrong direction.

[0049] The present utility model has been shown and described in detail above with reference to the accompanying drawings and preferred embodiments. However, the present utility model is not limited to these disclosed embodiments. Based on the above-mentioned multiple embodiments, those skilled in the art can know that more embodiments of the present utility model can be obtained by combining the code review means in the above different embodiments, and these embodiments are also within the protection scope of the present utility model.
