Description

Push-Lock Drawer Anti-Tipping Safety Device

This creation relates to a drawer locking device, especially a push-lock type drawer anti-tipping safety device that can prevent the drawer from being opened by mistake or falling out due to shaking.

Cabinets with drawers are essential storage supplies for every household, but when the drawers are pulled out, the weight of the contents will exert a rotational moment on the cabinets, so that if the drawers are built with heavy objects or multiple drawers are pulled out at the same time, the cabinets may be under stress. And the fall will cause injury to the user; or when an earthquake occurs, the cabinet may be shaken violently, and the drawer may slide out and the cabinet may fall. Therefore, some manufacturers have developed a "locker with locking effect" such as my country's Patent Certificate No. M562623, which can lock the drawer and unlock and open it only when the user needs it, which also prevents the drawer from being shaken and opened during an earthquake. A gap for accommodating the user's fingers must be left between it and the accommodating seat, which is not aesthetically pleasing.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a push-lock type drawer anti-overturning safety device, so as to improve the above-mentioned deficiencies of the conventional technology.

The main purpose of this creation is to provide a push-lock type drawer anti-overturning safety device, which prevents the drawer from being opened by mistake or falling out due to shaking, and is beautiful and easy to use.

In order to achieve the above-mentioned purpose, the push-lock type drawer anti-tipping safety device of the present creation includes a handle seat with a concave accommodating space; Inside, the operating part extends downward, the operating rod can be pivoted vertically and horizontally on the handle seat, the operating rod is protruded with a positioning part on the outside of the handle seat, the operating rod is combined with a first torsion spring, and one end of the operating rod is combined with a lock; a guide groove piece, which is combined with a side surface of the handle seat near the positioning part and has an inner groove, the inner groove forms a loop with two stopping points; and a positioning rod, one end of which is pivoted In the positioning portion, the other end of the positioning rod extends into and leans against the inner groove.

This creation uses a lock to lock the drawer, so the drawer equipped with this creation cannot be pulled out when the lock is locked, and it will not move due to shaking. Since the positioning rod will move when the operating lever is rotated, when the positioning rod falls into one of the stopping points, the position of the operating rod can be fixed, so that the creation can stay in the locked state or the open state; for example, in the locked state, use When the user presses the operating part to cause the operating rod to rotate, the positioning rod leaves the stop point and moves along the inner groove of the guide groove to another stop point and stops at another stop point, the lock also rotates to open, the creation is convenient In the open state, at this time, the operating portion extends outward for the user to grasp and pull out the drawer. When the user presses the operation part again in the open state, the positioning rod moves back to the original stop point, the lock is rotated and locked, and the operation part also returns to the position with the handle seat.

The inner groove may be an arrow-shaped loop. The inner groove of the guide groove piece can be divided into four sections, each stop point is respectively set in two of the four sections, and there is a stepped interval between the four sections, so that the positioning rod can follow the inner groove. When the slot slides, it can slide in the preset direction without going in the opposite direction. The positioning rod can be made of metal material, and the shape of the positioning rod can be designed so that when it is pivotally connected to the positioning portion, one end of the positioning rod leaning against the guide channel member is continuously pressed towards the bottom surface of the inner groove of the guide channel member by its own elastic force, so that the When the positioning rod moves to the section where the inner groove of the guide groove has different heights, it can continue to lean on the bottom surface of the inner groove of the guide groove without loosening.

In this invention, a damping gear can be arranged on the handle base, and the operating rod can have a gear part, the damping gear meshes with the gear part, and the damping gear slows down the speed of the operating rod when it rotates, so as to avoid injury to the user.

The lock can be pivoted to the operating lever by a second torsion spring, so that when the user opens the drawer and wants to close the drawer, he can first press the operating part to lock the creation, and then push the drawer back, the lock will contact the lock when the drawer is closed. When the lock lever is removed, it can be rotated and removed first, the drawer can be closed smoothly, and then the lock catch can be rotated back to the position where it is combined with the lock lever to lock.

There is no need to reserve a distance for fingers to pass through between the handle base and the operation part of this creation, so that the appearance of this creation is more concise and beautiful. This creation can be applied to various occasions such as: home, storage room, office and factory, etc. Increase the security of drawer cabinets.
