The present invention relates to a handle lock device of a portable VTR, and in particular, to prevent the handle from flowing unnecessarily while the handle of the VTR is folded.

In the conventional case, the VTR equipped with a steering wheel does not have a handle lock, so when the VTR set is mounted on a vehicle or transported without using the handle, the set moves or vibrates. As a result of the movement of the handle, friction noise is generated, and when the VTR set is dropped, the handle is easily broken or released from the set.

In order to solve this problem, the present invention is designed to install a locking device consisting of a knob (Knob) for locking the handle and a leaf spring for pushing the knob (Knob) inside the VTR set, the knob and knob pressure on the handle The purpose is to improve the quality of the product by installing a release device consisting of a spring and the fixing piece.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention consists of a lock part 1 installed in the VTR set and a release part 2 installed in the handle as shown in FIG. The lock part 1 which consists of the lock knob 1a which is inserted in the shape of the guide rib 1c, and is comprised so that it may be caught by the leaf | plate spring 1b, and The release part 2 in the shaped handle 3 consists of the release part 2 which the elastic spring 2b was fitted to the open knob 2a, and was fastened by the fixing piece 2c and the fixing piece 1d.

The designed operation state as described above is as follows.

First, when the handle is to be locked, as shown in FIGS. 2A and 2B, the lock knob 1a always operates in the "F" direction when there is no external force due to the elastic action of the leaf spring 1b. When locked, the inner surface of the handle 3 pushes the inclined surface A of the lock knob 1a so that the lock knob 1a moves in the "R" direction and the leaf spring 1b when the handle 3 is completely in contact with the VTR set. ), The lock knob 1a is moved to the jaw of the knob guide rib 1c due to the elastic action in the F direction, and the inclined portion is caught by the square groove 1e formed in the fixing piece 1d. The handle 3 is locked.

On the other hand, in the case of releasing the locked handle 3, when the knob surface protruding from the open knob 2a is pushed in the "R" direction, the elastic spring 2b positioned between the fixed piece 2c and the open knob 2a is opened. As it is compressed, it pushes the lock knob 1a, which is caught by the square groove 1e again, in the " R " direction to release it from the square groove 1e.

At this time, the leaf spring 1b has sufficient pressure so that the open knob 2a does not escape the square groove 1e.

Using this principle, pressing the open knob 2a and lifting the handle 3 in the "p" direction releases it from the locked state, and the handle 3 is in use.

As described above, the present invention can prevent noise generated by the movement of the handle when the VTR with the handle 3 is mounted on a vehicle or when the VTR is transported without using the handle. It is possible to prevent breakage and detachment of the handle and thus to improve the quality of the product.
