Description

The connector box pivot structure

Technical field

The utility model belongs to the box body coupling arrangement, and is especially relevant with a kind of connector box pivot structure.

Background technology

Cable splice closure is the equipment that continues that a kind of optical cable broken end connects or branch connects, and the cable splice closure box body is divided into upper and lower box body, and axle sleeve all is set on the upper and lower box body, uses coupling shaft to insert axle sleeve upper and lower box body is connected.Connector box for making things convenient for the joint operation, often need separate upper and lower box body in the fiber cable joint process, the traditional jointing box need be extracted coupling shaft and upper and lower box body could be separated, again coupling shaft is inserted when being linked and packed, so box body is easy to cause damage, dismounting is also very inconvenient.

The utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is exactly will overcome dismounting inconvenience that the existing upper and lower box body of cable splice closure bindiny mechanism exists, easily cause the defective of damage, and the connector box pivot structure device of a kind of compact conformation, easy accessibility is provided.For this reason, the utility model is by the following technical solutions:

The connector box pivot structure, comprise the axle sleeve that is arranged on the upper cartridge body, it is characterized in that: described pivot structure also comprises coupling shaft, have two on this coupling shaft and make with parallel axes and the plane that is parallel to each other that the cross section perpendicular to axis is cydariform on the coupling shaft, coupling shaft is connected as a single entity by support plate and lower box body, described axle sleeve is provided with opening, quite forms with the spacing on the plane of parallel axes on A/F and the coupling shaft to closely cooperate, and coupling shaft is arranged in bore sleeve.

Have connector box of the present utility model, when upper and lower box body need separate, as long as with the axle sleeve opening angle rotate to coupling shaft on the planar registration of parallel axes, coupling shaft just can be released from the opening of axle sleeve, realizes the separation of upper and lower box body; Corresponding upper and lower box body needs to connect, as long as with on axle sleeve opening and the coupling shaft with the planar registration of parallel axes, opening along the plane on the coupling shaft with the axle sleeve gland in coupling shaft, make coupling shaft be arranged in bore sleeve, axle sleeve can be the axle rotation with the coupling shaft, it is to release axle sleeve that coupling shaft has only thereon consistent with the plane of parallel axes and the opening direction on the axle sleeve, has guaranteed the stability of coupling shaft in axle sleeve.

As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:

Have a plurality of coaxial axle sleeves on the described upper cartridge body, keep at a certain distance away between each axle sleeve, the opening on the axle sleeve all in the same way; Described lower box body is provided with a plurality of coaxial coupling shafts, and coupling shaft lays respectively at the both sides of support plate, the axial plane on the coupling shaft all in the same way, support plate and axle sleeve intersect assembling.

Described support plate quantity is Duoed one than axle sleeve quantity, and support plate is arranged in order, and the coupling shaft on two support plates of head and the tail is positioned at the inboard of support plate.

Be provided with muscle between described axle sleeve and the upper cartridge body, the reinforcement fixation is played in the position of axle sleeve.

Described axle sleeve can be arranged on the lower box body, and corresponding, coupling shaft can be arranged on the upper cartridge body.

Use the utility model can reach following beneficial effect: by coupling shaft and box body are connected as one, to make structure more compact, cooperate assembling, make the separation easy disassembling of box body can't damage box body by axle sleeve opening and coupling shaft axial plane.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises 6 axle sleeves 2 that are arranged on the upper cartridge body 1, with 7 support plates 3 that are arranged on the lower box body 4, support plate 3 is arranged in order, the inboard of two support plates 3 of head and the tail is provided with coupling shaft 5, both sides are provided with coupling shaft 5 on middle 5 support plates 3, coupling shaft 5 on each support plate 3 is all coaxial, coupling shaft 5, support plate 3 and lower box body 4 form by die casting and are connected as a single entity, and have two on the coupling shaft 5 and make with parallel axes and the plane that is parallel to each other that the cross section perpendicular to axis is cydariform on the coupling shaft; Have certain distance between each axle sleeve 2 and form the gap, axle sleeve 2 is provided with opening 7, two plane-parallel spacings of opening 7 width and coupling shaft 5 quite form and closely cooperate, be provided with muscle 6 between axle sleeve 2 and the upper cartridge body 1, support plate 3 and axle sleeve 2 intersect assembling, make support plate 3 insert in the gap of 2 on axle sleeve, coupling shaft 5 is arranged in axle sleeve 2 inner chambers.

Have connector box of the present utility model, when upper and lower box body need separate, as long as with the axle sleeve opening angle rotate to coupling shaft on the planar registration of parallel axes, coupling shaft just can be released from the opening of axle sleeve, realizes the separation of upper and lower box body; Corresponding upper and lower box body needs to connect, if with on axle sleeve opening and the coupling shaft with the planar registration of parallel axes, opening along the plane on the coupling shaft with the axle sleeve gland in coupling shaft, make coupling shaft be arranged in bore sleeve, axle sleeve can be that axle rotates with the coupling shaft.
