KR20110009635U - Handle device for withdrawal rotation type - Google Patents

Abstract

Designed to secure the handle of the rotary drawer type handle device used in indoor and outdoor communication facilities and switchboards, the handle is positioned by combining a spring and a bearing ball at the center of the rotating shaft, and making a seating groove corresponding to the handle. It can be fixed on the ball, and the bearing ball comes in contact with the handle during operation, so it is soft and generates little noise.

Description

Handle structure of pull out rotating handle {HANDLE DEVICE FOR WITHDRAWAL ROTATION TYPE}

As a method of opening and closing doors such as storage boxes such as switchboards, the drawer rotation handle device for opening and closing the door is used. Accordingly, the function of opening and closing the door by installing or not hanging on the storage box body or the bracket attached to the body. The present invention relates to a structure that can be stopped at a specific position when the handle handle is pulled out of the handle body in the handle structure.

The domestic patent withdrawal locking door lock handle device (Reg. No. 0122079) and the plane handle device (Reg. No. 20-0143559), etc. proposed a method to stop the handle of the rotation pull-out handle device at a certain position, The problem is solved by the use of a branched spring, the handle and the shape of the contact surface of the rotating shaft.

In many storage boxes that require waterproofing, sealing and locking devices such as communication facilities, switchboards, and the like, the above draw-out handle device is used. The handle device of the present invention can reduce the unit cost due to its excellent assembly productivity due to the simplicity of the structure. Compared with other steering wheel devices, it operates smoothly and generates less noise.

Conventional rotary draw-out handle device is a spring or spring washer, flat washer, etc. by complex configuration of the shape and structure of the rotating shaft connecting the handle handle and the clasp to achieve the above object in addition to the waterproof and airtight function of the storage box The use of the structure is complicated and the productivity is low, but the present invention aims to improve the productivity by smoothing the movement of the handle more smoothly, reducing noise, and simplifying the structure.

When the side on which the catch 18 is fixed is called the lower side, as shown in FIG. By the interaction of the handle 15 coupled to the pinholes 22a and b of the handle 15 corresponding to the 31 with the coupling pins 16a and b, and the bearing ball seating grooves 21a and b inside the handle. After being pulled out of the handle body 11, the handle is fixed by the force of the coil spring at a predetermined angle and is in a rotatable state from side to side.

Conventionally, by using a rotating shaft having a structure with a spring outside the rotating shaft to change the length of the rotating shaft itself, the spring force is the strongest at the critical point so that the handle is stored in the handle body around the critical point or drawn out so that the left and right rotations are possible. According to the design of the contact surface of the rotating shaft and the handle to be in a state of being complicated, the structure is complicated and the functions are made under the handle fixing pin, and the noise generated when passing the critical point by the operation of the spring washer and the flat washer. there was. In the present invention, by rotating the screw hole for fixing the clamp 18 in the center of the shaft of the rotary shaft 14, or by arranging holes for coupling the spring 12 and the bearing ball 13 coaxially with the screw hole from the upper side, the rotary shaft itself The structure has been simplified, the bearing ball 13 is operated inside the handle 15 corresponding to the upper shape of the rotary shaft 14, and soft and less noise occurs.

In the present invention, a detailed description of the watertight and sealed functions of the storage box will be omitted and briefly explained. The watertight function can be made by putting an O-ring on the lower side of the rotating shaft to be in close contact with the handle body. It is possible by inserting a spring washer in between to pull the storage box body and door.

The handle 15 of the handle is pulled up and down about the coupling pin 16 from the handle body 11 so as to be rotated left and right about the rotation axis 14 so as not to be returned to its original position by its own weight at a predetermined angle. The method is as follows.

The lower side of the rotating shaft 14 has a shape as shown in the drawing so that the stopper 18, the stopper 17 can function, it needs a circular shaft shape to be rotatable in the handle body to the upper side and the O-ring It is shaped like stairs. The circular plane thereon forms a contact surface 32 of the rotating shaft and corresponds to the contact inclined surface 23 of the handle. The upper handle 15 is coupled to the coupling pin 16 by the structure that can be rotated up and down, in the embodiment of the present invention has a circular shape. In the center of the shaft 14, the diameter of the upper part is slightly smaller so that the hole corresponding to the fastening screw 19 penetrates to the upper side, but the bearing ball 13 does not fall out, so that the bearing ball 13 and the coil spring ( 12), Combine in the order of tanning bolts. In the casting product, instead of penetrating as described above, only the fastening screw 19 is coupled to the lower side of the rotating shaft 14, and the coil spring 12 and the bearing ball 13 are coupled to the upper side of the rotating shaft 14, and then assembled. It is also possible to forcibly reduce the diameter.

Handle handle 15 has a pinhole (22a, b) coupled to the rotating shaft 14, the concave portion of the shape corresponding to the upper side of the rotating shaft 14 to enable vertical rotation around the coupling pin (16a, b), Bearing ball seating grooves 21a and b corresponding to when the handle 15 is stored in the handle body 11 in the concave portion and when the handle 15 is drawn out and fixed in the left-right rotation standby state, and the contact surface 32 of the rotating shaft corresponding thereto. And contact inclined surfaces 23a and b in contact with each other. The size of the bearing ball seating groove (21a, b) is determined in consideration of the size and manufacturing error of the bearing ball (13).

In the state where the handle is stored in the handle body, the bearing ball 13 is seated in the seating groove 21a. The handle 15 is lifted up by hand by the hand enough to overcome the compressive force of the spring, and then starts to rotate up and down. When the bearing ball 13 is then seated by itself to the next seating groove (21b) the handle is fixed at that angle until a certain force is applied.
