Description

Door stop base

Technical Field

The utility model belongs to the field of furniture articles, and particularly relates to a base of a door stop for preventing a door leaf from being opened or closed.

Background

The door stop is a device which is arranged on the door leaf to be in contact with the floor or the ground, thereby realizing temporary locking of the door leaf during the opening or closing process of the door leaf. Unlike a door stopper fixed only at a maximum open position, the door stopper can lock the door leaf at an arbitrary position, thereby functioning to prevent the door leaf from being opened or closed. For example, in a household with pets or infants, a door stop may be used to fix a bedroom door leaf in a position where only a certain gap is opened, thereby serving to ventilate or to prevent closing of fingers from pinching.

The prior door stops generally adopt wedge-shaped pieces to act between the floor and the bottom end of the door leaf or are obliquely supported on the floor so as to play a role of unidirectional locking, so that the prior door stops usually only need to be fixed on the front surface and the rear surface of the door leaf. For door stops requiring a two-way locking, the fixation on the door leaf surface alone is insufficient.

Accordingly, it is necessary to provide a door stop base that can be fixed or attached to both the surface and the bottom end surface of the door leaf.

Detailed Description

The following describes the protection scope of the present utility model in detail with reference to the embodiments of the present utility model and the accompanying drawings. It should be noted that the following descriptions are examples, and are intended to facilitate understanding and not to limit the scope of the present utility model. All conventional variations made on the basis of the examples are intended to fall within the scope of the utility model.

As shown in fig. 1, a door stop for locking a door leaf, preferably for an indoor door, such as a bedroom door, is fixed on the one hand to a first member on a door sector and on the other hand has a further member which is pivotally movable and is intended to lock the door leaf against the ground.

The door stopper is integrally formed of a base 100 and a locking member 200, wherein the base 100 is used for being fixed to a door leaf, and the locking member 200 is rotatably connected to the base 100 and is used for abutting against a floor (or the ground) to achieve the effect of fixing the door leaf, for example, when the locking member 200 is in a position shown in fig. 1, an abutting end arranged at the lower end of the locking member 200 contacts with the floor to fix the door leaf so as to prevent the door leaf from being closed or opened, and similarly, when the locking member 200 rotates around a rotating shaft 202 by a certain angle, an unlocking state can be formed to release the fixing effect of the door leaf, for example, the locking member 200 is abutted against the surface of the door leaf after rotating by 180 degrees so as to simultaneously achieve storage in the unlocking state of the locking member 200.

As shown in fig. 1-2, shaft holes are respectively formed on the base 100 and the locking member 200, a shaft pin 203 is inserted between the shaft holes, so as to realize the rotation pivoting of the locking member 200 and the base 100, and a rotating shaft 202 is formed.

As shown in fig. 3 to 4, the base 100 is composed of two parts, that is, a base body 110 and a base adjuster 120, the base adjuster 120 is disposed to be relatively movable with respect to the base body 110, the base body 110 is used to be attached to the front surface or the rear surface of the door leaf, the base adjuster 120 is composed of an L-shaped adjuster 121, the L-shaped adjuster 121 is composed of a first arm 1211 and a second arm 1212 which are substantially perpendicular to each other so as to be formed as an L-shaped member, the two arms are integrally formed, the first arm 1211 is used to be adjusted by telescoping movement within the base body 110, and the second arm 1212 is used to be attached to the lower surface of the door leaf, that is, the bottom end surface of the door leaf.

The base body 110 is further formed by the first body 111 and the second body 112 being fastened to each other, preferably the second body 112 is also fastened to the first body 111 by a screw, and a cavity 113 is formed inside the base body 110 for the telescopic movement of the first arm 1211 therein. A connection stage 114 is also convexly formed at the front surface of the first body 111, and a shaft hole 115 is formed on the connection stage 114 for the shaft pin 203 to be accommodated therein. A lock cavity 116 is also formed within the connection block 114 for the locking member 122 to be disposed therein. One end of the locking member 122 is propped against the bottom wall of the lock cavity 116 through a spring, and the other end of the locking member 122 is provided with a toothed second locking member 126, and the second locking member 126 is provided with unidirectional teeth which allow the base adjusting member 120 to retract upwards and prevent the base adjusting member from extending downwards. As shown in fig. 5-6, the second arm 1212 of the base adjusting member 120 is correspondingly provided with a toothed first locking member 123, and the first locking member 123 is also formed by unidirectional tooth arrangement to achieve the purpose of unidirectional locking of the base adjusting member 120. Moreover, two sides of the first arm 1211 are respectively provided with a spring plate 124, and a clamping protrusion 125 is formed at the end of the spring plate 124, where the clamping protrusion 125 is used to be clamped with the base body 110 to limit the upward displacement of the base adjusting member 120, for example, the clamping protrusion 125 is abutted against the lower end surface of the base body 110 or clamped in a groove on the side wall of the cavity 113, where the purpose of presetting the retraction distance before mounting the base adjusting member 120 can be achieved when the clamping protrusion 125 is abutted against the lower end surface of the base body 110, and the purpose of preventing the upward displacement of the base adjusting member 120 can be achieved when the clamping protrusion 125 is clamped in the groove on the side wall of the cavity 113, so that the upward displacement of the base adjusting member 120 relative to the base body 110 is locked by the mutual clamping action between the clamping protrusion 125 and the base body 110, and the downward displacement is locked by the interaction between the first locking member 123 and the second locking member 126.

Of course, in other embodiments, the upward and downward displacement of the base adjusting member 120 relative to the base main body 110 may be locked by the same mechanism, for example, the second locking member 126 and the first locking member 123 are both unidirectional teeth and at least one is bidirectional teeth (i.e. the second locking member 126 needs to be unlocked when both the upper and lower directions can be locked and displaced), or the locking structures of the two directions are reversed, that is, the first locking member 123 and the second locking member 126 are matched to lock the upward displacement, and the locking protrusion 125 is engaged with the base main body 110 to lock the downward displacement.

And a limiting hole 117 is further formed below the shaft hole 115, and a limiting clamp 127 of the locking piece 122 is clamped in the limiting hole 117, so that when the locking piece 122 needs to be unlocked to the base adjusting piece 120, the limiting clamp 127 is forced to move along the direction away from the base adjusting piece 120, and the second locking piece 126 is separated from the first locking piece 123.
