Description

Technical Field

[0001] The utility model belongs to the field of furniture products, and in particular relates to a door stop base used for preventing a door leaf from opening or closing. Background Art

[0002] A door stop is a device installed on a door leaf to contact the floor or ground, temporarily locking it during opening or closing. Unlike door suction, which only locks the door at its maximum open position, a door stop can lock the door leaf at any position, preventing it from opening or closing. For example, in homes with pets or infants, a door stop can be used to secure a bedroom door in a slightly open position to allow for ventilation or prevent fingers from being pinched when closing.

[0003] Existing door stops typically use a wedge-shaped member acting between the floor and the bottom end of the door leaf, or are supported diagonally on the floor, to achieve a one-way locking effect. Therefore, they usually only need to be fixed on the front and back surfaces of the door leaf. For door stops that require two-way locking, fixing only on the door leaf surface is not enough.

[0004] Therefore, it is necessary to provide a door stop base that can be fixed or fitted on the surface and bottom end surface of the door leaf at the same time. Utility Model Content

[0005] The purpose of the utility model is to provide a door stop base which can be telescopically adjusted to facilitate the installation operation of the door stop base and can simultaneously adhere to the surface and the bottom end surface of the door leaf.

[0006] To achieve the above objectives, the following solutions are adopted:

[0007] A door stop base is used to be fixed to a door leaf so that a locking member of the door stop is pivotally connected thereto, the door stop base comprising:

[0008] The base body is used to be fitted and fixed to the surface of the door leaf, and a cavity is provided in the base body.

[0009] The base adjustment member is an L-shaped member and is arranged to be telescopically movable relative to the base body; the base adjustment member includes a first arm and a second arm, the first arm is assembled in the cavity, and the second arm extends in a direction perpendicular to the first arm. And,

[0010] A telescopic locking mechanism acts between the base body and the base adjusting member to lock the telescopic movement of the base adjusting member.

[0011] According to the above-mentioned door stop base, the telescopic locking mechanism includes a first locking device, the first locking device includes a first locking member arranged on the first arm and a locking member movably arranged in a direction perpendicular to the first arm, the locking member is provided with a second locking member at the first end close to the first arm, the second locking member includes a tooth block, and the first locking member is a rack.

[0012] According to the door stop base, a connecting platform is protruding from one side of the base body, a lock cavity is provided in the connecting platform, and the locking member is provided in the lock cavity.

[0013] Preferably, a through-going limiting hole is formed on the side wall of the connecting platform, and the limiting clip of the locking member is engaged in the limiting hole.

[0014] According to the above-mentioned door stop base, the second locking member includes a one-way tooth block, and the first locking member is a one-way rack.

[0015] According to the above-mentioned door stop base, an axis hole is further provided on the connecting platform for allowing an axis pin to pass therethrough.

[0016] According to the above-mentioned door stop base, the telescopic locking mechanism includes a second locking device, which includes a spring sheet arranged on at least one side of the first arm and a card edge formed at the lower edge of the side wall of the cavity. A card protrusion is provided at the end of the spring sheet, and the card protrusion is connected to the card edge to limit the maximum telescopic stroke of the base adjustment member.

[0017] The door stop base of the utility model has the following beneficial effects:

[0018] 1. The door stop base can be used to fix the base body to the surface of the door leaf in one direction. If it needs to be installed on the outside of the door leaf, it is fixed to the outer surface of the door leaf; if it needs to be installed on the inside of the door leaf, it is fixed to the inner surface of the door leaf; on the other hand, it also has a base adjustment member that can be telescopically movable in the vertical direction, so that after installation, the second arm of the base adjustment member can contact or be close to the bottom end surface of the door leaf, meeting the fixing strength requirements of the two-way door stop.

[0019] 2. Since the door stop base fits or contacts the door leaf in two different directions at the same time, it can be fixed to the door leaf by gluing without using self-tapping screws or fixing with screws after drilling holes, thereby simplifying the installation operation and avoiding damage to the door leaf.

DETAILED DESCRIPTION

[0028] The following is a detailed description of the scope of protection of the present invention in conjunction with the embodiments and accompanying drawings of the present invention. It should be noted that the following descriptions are all examples, and their purpose is to facilitate understanding rather than to limit the scope of protection of the present invention. All routine changes made based on the embodiments should fall within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a door stop for locking a door leaf is preferably used for an interior door, such as a bedroom door. On the one hand, the door stop is fixed to a first component on the door leaf, and on the other hand, it has another component that is pivotable and used to contact the ground to lock the door leaf.

[0030] The door stop is composed of a base 100 and a locking member 200, wherein the base 100 is used to be fixed to the door leaf, and the locking member 200 is rotatably connected to the base 100 and is used to contact the floor (or ground) to achieve the function of fixing the door leaf. For example, when the locking member 200 is in a position such as Figure 1In the position shown, the abutment end provided at the lower end of the locking member 200 contacts the floor, thereby fixing the door leaf and preventing it from closing or opening; similarly, when the locking member 200 rotates a certain angle around the rotating shaft 202, it can form an unlocked state to release the fixing effect on the door leaf, for example, after rotating 180°, it can be attached to the surface of the door leaf to simultaneously realize the storage of the locking member 200 in the unlocked state.

[0031] like Figure 1-2 As shown, shaft holes are respectively provided on the base 100 and the locking member 200 , and the shaft pin 203 is passed through the shaft holes to realize the rotational pivot connection between the locking member 200 and the base 100 , and form a rotating shaft 202 .

[0032] like Figure 3-4 As shown, the base 100 is composed of two parts, namely, a base body 110 and a base adjusting member 120. The base adjusting member 120 is arranged relative to the base body 110 so as to be relatively movable and adjustable. The base body 110 is used to fit onto the front surface or rear surface of the door leaf. The base adjusting member 120 is composed of an L-shaped adjusting member 121. The L-shaped adjusting member 121 is composed of a first arm 1211 and a second arm 1212 that are substantially perpendicular to each other to form an L-shaped component. The two arms are integrally formed. The first arm 1211 is used to be telescopically movable within the base body 110 for adjustment, and the second arm 1212 is used to fit onto the lower surface of the door leaf, that is, the bottom end face of the door leaf.

[0033] The base body 110 is further formed by the first body 111 and the second body 112 being interlocked with each other. Preferably, the second body 112 is also fastened to the first body 111 by screws. A cavity 113 is formed inside the base body 110 for the first arm 1211 to move telescopically therein. A connecting platform 114 is also convexly formed on the front of the first body 111, and an axial hole 115 is formed on the connecting platform 114 for the axial pin 203 to be positioned therein. A lock cavity 116 is also formed inside the connecting platform 114 for the locking member 122 to be positioned therein. One end of the locking member 122 is abutted against the bottom wall of the lock cavity 116 via a spring, and a toothed second locking member 126 is formed at the other end. The second locking member 126 is a one-way tooth that allows the base adjustment member 120 to retract upward and prevents it from extending downward. As shown in FIG. Figure 5-6As shown, a rack-shaped first locking member 123 is correspondingly provided on the second arm 1212 of the base adjusting member 120 . The first locking member 123 is also composed of a unidirectional tooth arrangement to achieve the purpose of unidirectional locking of the base adjusting member 120 . The locking cam 125 is used to lock the bottom surface of the base body 110 and limit the upward displacement of the base adjustment member 120, for example, by abutting against the lower end surface of the base body 110 or being locked in the groove of the side wall of the cavity 113. When the locking cam 125 abuts against the lower end surface of the base body 110, the purpose of presetting the retraction distance of the base adjustment member 120 before installation can be achieved. When the locking cam 125 is locked in the groove of the side wall of the cavity 113, the retraction distance before installation can be preset or multiple grooves can be set for user adjustment, so as to achieve the purpose of preventing the base adjustment member 120 from moving upward, so that the upward displacement movement of the base adjustment member 120 relative to the base body 110 is locked by the mutual engagement between the locking cam 125 and the base body 110, and the downward displacement movement is locked by the interaction between the first locking member 123 and the second locking member 126.

[0034] Of course, in other embodiments, the upward and downward displacement activities of the base adjustment member 120 relative to the base main body 110 can also be locked by the same mechanism. For example, the second locking member 126 and the first locking member 123 mentioned above are both one-way teeth, and at least one is a two-way tooth (that is, they can be locked in both the upper and lower directions, and the second locking member 126 needs to be unlocked when displacing); or the locking structures in the two directions mentioned above are swapped, that is, the upward displacement movement is locked by the cooperation of the first locking member 123 and the second locking member 126, and the downward displacement is locked by the engagement of the protrusion 125 with the base main body 110.

[0035] A limiting hole 117 is also provided below the shaft hole 115, and the limiting card 127 of the locking member 122 is engaged in the limiting hole 117. When it is necessary to release the locking member 122 from the base adjusting member 120, force is applied to the limiting card 127 to make it move in a direction away from the base adjusting member 120, so that the second locking member 126 is disengaged from the first locking member 123.
