[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] refer to Figure 1 This is a buried optical fiber connector 11 box 1, with a connector 11 provided on the top, and a dust cap 2 installed on the connector 11. In order to strengthen the installation of the dust cap 2, a soft rope 3 is usually used for installation. The rope 3 includes two rings 31, and the two rings 31 are connected by a connecting rope 32. The dust cap 2 includes a tube body 21 that is sleeved on the outer ring of the connector 11 and a cap body 22 installed on the top of the connector 11. During installation, one of the rings 31 will need to be sleeved on the connector 11, and then the tube body 21 will need to be sleeved on the outer ring of the connector 11 and pressed on the ring 31, and then the other ring 31 will be placed on the top of the connector 11, and finally the cap body 22 will be installed on the connector 11 and pressed on the ring 31. In the prior art, the ring sleeve 31 is usually manually aligned with the joint 11, and then the ring sleeve 31 is pressed down to make it fit on the joint 11. Since the ring sleeve 31 and the joint 11 fit tightly and the area of ​​the ring sleeve 31 is small, the area of ​​manual action on the ring sleeve 31 is limited, and it is difficult to quickly put the ring sleeve 31 on the joint 11, which is relatively inefficient.

[0024] Based on this, the present invention provides the following embodiments, with reference to Figure 3-4 A buried optical fiber connector 11 box 1 rope 3 installation fixture, comprising: a positioning inner tube 4, one end of the positioning inner tube 4 is provided with a connecting portion 41; a sleeve 5, a guide sleeve is arranged on the positioning inner tube 4, and the end of the sleeve 5 away from the positioning inner tube 4 is provided with an abutment portion 51; an elastic member 7, installed between the connecting portion 41 and the abutment portion 51, so that the sleeve 5 is subjected to elastic resistance when pressed down, and when the elastic member 7 is in a free state, the end of the positioning inner tube 4 away from the connecting portion 41 exceeds the end of the sleeve 5 away from the abutment portion 51 to form a protruding portion 42.

[0025] It is understandable that the positioning inner tube 4 and the sleeve 5 are guided together, and the guiding structure can be directly the axial hole guide between the tubes, or it can be matched with a limiting guiding structure such as a slide block on the basis of the axial hole guide, thereby enhancing the stability of the guidance of the positioning inner tube 4 and the sleeve 5. As for the shape of the outer wall of the sleeve 5, it can be a round rod or a square tube, etc., but is not limited to this. The connecting portion 41 and the abutting portion 51 are components used to abut the elastic member 7. For example, it can be a solid structure that seals the sleeve 5 and the positioning inner tube 4, or it can be a hollow structure, etc., but is not limited to this. The elastic member 7 is a component that provides elastic resistance to the downward pressure of the sleeve 5, and can be, for example, a spring or a shrapnel, etc., but is not limited to this. The protruding portion 42 is a component used to position the ring sleeve 31, and is adapted to the inner ring shape of the ring sleeve 31. For example, if the inner ring of the ring sleeve 31 is circular, the corresponding protruding portion 42 is cylindrical. If the inner ring of the ring sleeve 31 is square, the corresponding protruding portion 42 is square tubular, etc., but is not limited to this.

[0026] So set up, refer to Figure 4 First, put the ring 31 on the protruding part 42, and then position the bottom of the inner tube 4 against the top of the joint 11. Figure 5 , press the sleeve 5 so that the sleeve 5 is pressed down, and the sleeve 5 will push the ring sleeve 31 downward so that the ring sleeve 31 is sleeved on the joint 11 and moved to the bottom of the joint 11. In this way, the ring sleeve 31 can be installed quickly.

[0027] In some embodiments, a guide rod 6 is further included, one end of which is mounted on the connecting portion 41, and the other end is guided and matched with the abutment portion 51. It is understandable that the guide rod 6 and the connecting portion 41 can be connected as one piece, or can be threadedly connected using a screw, etc., but is not limited thereto. As for the matching of the elastic member 7 and the guide rod 6, when the elastic member 7 adopts a spring, the spring is sleeved on the guide rod 6, and the two ends are respectively against the connecting portion 41 and the abutment portion 51. The guiding matching of the guide rod 6 and the abutment portion 51 adopts an axial hole guiding matching. Specifically, a guide hole 52 is provided on the abutment portion 51, and the guide rod 6 is inserted into the guide hole 52. With such a configuration, the installation of the guide rod 6 can strengthen the guiding stability of the sleeve 5 and the inner tube, and can also make the deformation of the elastic member 7 stable.

[0028] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
