Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A cabinet door locking mechanism is shown in figures 1 to 3 and comprises a mounting seat 2 fixed on a cabinet door 1 and a support rod 4 hinged on the cabinet body 3; the front end of the stay bar is provided with a locking piece 5 which is inserted in the mounting hole of the stay bar; the locking piece comprises a limiting column 6, a guide column 7 is arranged at the lower end of the limiting column, and an anti-falling plate 8 is arranged at one end of the limiting column, which extends out of the mounting hole upwards; a limiting seat 9 is fixed on the mounting seat, a sliding groove 10 is formed in the limiting seat along the length direction, and at least one fixing position 11 is arranged on the sliding groove.

The stay bar is arranged in a horizontal state and is installed on the cabinet bottom plate 12 or the door frame 13 through a rotating column 14. In an alternative embodiment, the rotating column may be mounted on a support, and the support is fixed on the cabinet bottom plate 12 or the door frame 13, so that the support can be used to increase the position of the stay bar, and a locking member at the front end of the stay bar is ensured to be stably matched with the limiting seat.

The rotating column is vertically arranged, and the support rod rotates along the circumferential direction of the rotating column. Generally, be equipped with on the above-mentioned vaulting pole with the post complex via hole rotates, this via hole adopts slot hole or oval hole, rotates the post and wears to establish in the via hole, guarantees that the vaulting pole has certain activity, and the vaulting pole of being convenient for is equipped with the lock part and raises and put down, avoids the card dead.

The guide post is in sliding fit with the sliding groove, the connection relation between the support rod and the limiting seat is guaranteed, when the cabinet door is closed, the support rod can be stored along with the rotation of the rotating post, the locking piece can slide in the sliding groove after the cabinet door is opened, and when the cabinet door falls into the fixing position, the limiting post is matched with the fixing position. Of course, also can artificially lift the locking piece end of the stay bar, after the locking piece is in contact fixed relation with the fixed position, the stay bar is rotated into the cabinet body or is detached, and then the cabinet door is closed.

Generally, the guide post and the limit post are integrally formed. In an alternative embodiment, the position-limiting post portion of the locking member is in sliding engagement with the mounting hole, i.e., the position-limiting post portion is axially (vertically) slidable along the mounting hole. In order to prevent the locking member from escaping from the mounting hole, a stopper plate 15 may be provided at the lower end of the stopper post, as shown in fig. 4. It should be pointed out that anticreep board and limiting plate all can the detachable install on spacing post to in the assembly of lock piece, as the example, spacing post upper portion is equipped with the external screw thread structure, is equipped with the mounting hole on the anticreep board, and be equipped with the internal thread structure with the external screw thread structure complex of spacing post at the mounting hole inner wall. Of course, other connection forms can be adopted by those skilled in the art, as long as the anti-falling plate and the limiting plate can be installed, and then the locking piece is prevented from falling off from the stay bar.

In an optional embodiment, the fixing position includes a circular fixing hole, the diameter of the fixing hole is greater than the width of the sliding groove, the sliding groove radially penetrates through the fixing hole, the locking piece at the front end of the stay bar slides to the fixing hole along the sliding groove, the locking piece falls into the fixing hole due to self weight, and therefore the stay bar can fix the cabinet door and prevent the angle of the cabinet door from changing.

After the cabinet door is opened, along with the angle change that the cabinet door was opened, the locking piece can slide along the spout, and the locking piece on the vaulting pole slides in the fixed orifices and blocks and die, then fixes the cabinet door, and the cabinet door can not be closed to the outside, and the cabinet door can not open bigger angle because of the mistake bumps yet. When needs were closed the door (or be equipped with a plurality of fixed positions, when needs adjustment fixed position), then upwards mention (perhaps with the lock piece jack-up that makes progress gently the one end that the vaulting pole has the lock piece), make lock piece and fixed orifices remove fixed relation, the guide portion of the lock piece (on the vaulting pole) can slide in the spout, and then close the cabinet door, such structural design, the stability of cabinet door when having effectively guaranteed the operation, and, avoided the mistake to close the door and led to the fact the injured condition of operating personnel.

The cabinet door fixing device is reasonable in structural design, the cabinet door can be fixed after the locking piece at the front end of the stay bar falls into the fixing position on the limiting seat, loss or accidents caused by instability of the cabinet door are avoided, the safety is high, and the using effect is good. And, when setting up a plurality of fixed positions on spacing seat, can also adjust the cabinet door as required and open (fixed) angle, it is very convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
