Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

A rotary connecting piece is shown in figures 1-4 and comprises a fixed seat 1, a bolt 2, a spring 3 and a clamp spring 4; the bolt 2 is similar to a U-shaped structure integrally, the bolt 2 comprises a first pin rod 21 and a second pin rod 22, the fixed seat 1 comprises a bottom plate and a supporting plate, and the fixed seat 1 is provided with a first mounting hole 5 for inserting the first pin rod 21 and a second mounting hole 6 for inserting the second pin rod 22; when the connecting piece is used specifically, firstly, the connecting piece is assembled in a rotating mode, specifically, the first pin rod 21 and the second pin rod 22 of the bolt 2 are respectively inserted into the first mounting hole 5 and the second mounting hole 6 of the fixing seat 1, a structure that the bolt 2 is connected with the fixing seat 1 in a sliding mode is formed, the spring 3 and the clamp spring 4 are mounted on the second pin rod 22, and the clamp spring 4 and the spring 3 are mounted at the position, located between the two support plates, of the second pin rod 22. After the assembly is finished, two ends of the bolt 2 are respectively positioned at two sides of the first mounting hole 5 and the second mounting hole 6, and the first mounting hole 5 and the second mounting hole 6 penetrate through the two support plates due to the fact that a certain distance is reserved between the two support plates, so that two-point support with a certain span on the bolt 2 can be achieved through the first mounting hole 5 and the second mounting hole 6, and the bolt 2 is more stably mounted; wherein, the ends of the first pin rod 21 and the second pin rod 22 on the same side are connected with each other to form a whole, thus increasing the operable position of the bolt 2 and facilitating the operation.

When the connecting piece is used, the rotating connecting piece in the application is fixed on a rotating component (a door panel or a cover plate 8 and the like), one end face of a bottom plate of the fixing seat 1 is an installation base face, the installation base face is attached to a side wall of the rotating component, the fixing seat 1 is fixed on the rotating component through welding, screw connection or other modes, at the moment, the first pin rod 21 is close to the edge of the rotating component, the second pin rod 22 is located at a position far away from the edge of the rotating component, the length of the first pin rod 21 is larger than that of the second pin rod 22, the axis of the first pin rod 21 is the rotating center of the rotating component (the door panel or the cover plate 8 and the like), the first pin rod 21 can penetrate through the door panel or the cover plate 8 to be rotatably connected with the box body 9 or the door frame and the like, and the second pin rod 22 cannot penetrate through the door panel or the cover body. During specific installation, if the bolt 2 is a single-rod bolt, the accessories such as the spring 3, the clamp spring 4 and the like are generally installed at the position of the first pin rod 21, and interference is easily generated due to the fact that the accessory is relatively close to the edge of the cover body or the door panel; in the present application, due to the double-rod (first pin 21 and second pin 22) structure design of the latch 2, the accessory can be mounted on the second pin 22 away from the edge of the rotating component, so that the interference is reduced, and the mounting is facilitated.

In order to facilitate the installation of jump ring 4, circular slot 7 has been seted up on the outer fringe face of second pin pole 22 in this application, jump ring 4 is installed in circular slot 7, spring 3 is installed between jump ring 4 and one of them backup pad, spring 3 can install between arbitrary backup pad and jump ring 4, wherein, spring 3 can place between jump ring 4 and backup pad and make it hold certain elasticity (both ends are not connected with jump ring 4 or backup pad), spring 3's both ends also can be connected with jump ring 4 and backup pad respectively. When the box is used, the spring 3 enables the first pin rod 21 to be simultaneously inserted into the cover plate 8 and the box body 9 through self elasticity, so that the rotary connection between the cover plate and the box body is realized, and when the box is used, a user can enable the first pin rod 21 to be separated from the box body 9 by drawing the plug pin 2, so that the box body 9 and the cover body are detached.

In order to facilitate the user when carrying out plug operation to bolt 2, have great operating space, the contained angle between the plane that the central line of first mounting hole 5 and the central line of second mounting hole 6 formed and the installation base face is 30 in this application, the distance between first mounting hole 5 and the installation base face is less than the distance between second mounting hole 6 and the installation base face, exemplify with the connection of box 9 and apron 8, see the drawing, can see such design, can make bolt 2 whole and lid become certain angle, increased the angle between bolt 2 one side and apron 8, the hand of the operating personnel of being convenient for like this stretches into bolt 2 position and conveniently operates bolt 2.

Still further, in the present application, the first pin 21 and the second pin 22 are parallel to each other and are spaced apart from each other by a distance of 2-3cm. Distance between the two can hold operating personnel's finger and insert like this, when the operation, can hook the one end of first pin 21 and second pin 22 interconnect through the finger and operate, wherein the connection position rounding off of first pin 21 and second pin 22 interconnect one end avoids fish tail operating personnel's finger, the equal chamfer of the other end of first pin 21 and second pin 22 is handled, improve whole pleasing to the eye effect, it is downthehole to be convenient for first pin 21 to insert on the box 9.

In conclusion, the rotary connecting piece consisting of the fixed seat 1 and the bolt 2 with the double-rod structure is arranged, so that the interference phenomenon between the bolt 2 and the edge of the cover body in the installation process can be reduced when the rotary connecting piece is used, and the installation efficiency is improved; meanwhile, the operable position of the bolt 2 is increased, so that the operation is convenient; and because fixing base 1 self has certain width, when using, fixing base 1 is great with the area of contact of apron 8 (the contact site of the bolt 2 structure of current single pole and apron 8 generally is a straight line with the center of rotation collineation), and the rotation connecting piece in this application can adapt to the apron 8 of great weight and volume like this, and the wholeness can be better.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
