Description

Technical Field

[0001] The utility model relates to the field of anti-mislocking devices, in particular to an anti-mislocking device for an intelligent door lock. Background Art

[0002] An anti-theft door is a door equipped with an anti-theft lock that can resist abnormal opening under certain conditions within a certain period of time. It has certain security protection performance and meets the corresponding anti-theft security level.

[0003] Anti-theft doors are usually equipped with an anti-locking device on the inner handle. The existing anti-locking device performs anti-locking operation by turning a knob. When an external force or a child twists the knob by mistake, the anti-locking device is easily mislocked, thereby affecting the user's entry from the outside. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-mislocking device for a smart door lock to solve the problems raised in the above-mentioned background technology, which has the advantage of preventing mis-touch.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-mislocking device for a smart door lock, comprising a shell, the shell is provided with a first through groove penetrating the shell, the shell is connected to a rotary rod through the first through groove, one end of the rotary rod is integrally connected with a rotary cover, a spring is arranged between the rotary cover and the shell, a second through groove penetrating the rotary rod is provided on the side of the rotary rod, the rotary rod is connected to a limiting rod through the second through groove, a limiting plate is integrally connected to one side of the shell, the limiting plate is provided with a limiting groove for accommodating the limiting rod, and the rotary rod is sleeved with a limiting ring.

[0006] By adopting the above technical solution, since the limit rod is in the limit groove of the limit plate and cannot rotate, the rotary rod will also be unable to rotate and the rotary cover will be unable to rotate. Therefore, when the rotary cover is accidentally touched, the rotary cover cannot be rotated. When the rotary cover needs to be rotated, it is necessary to press the rotary cover to drive the rotary rod to move inward and then drive the limit rod to move inward. When the limit rod moves out of the limit groove, the rotary cover can be rotated. When there is no external force, the spring applies an outward force to the rotary cover, and a part of the limit ring is in the limit groove. Therefore, the setting of the limit ring can prevent the rotary rod from passing through the first through groove.

[0007] As a further solution of the utility model: a panel is provided on one side of the shell, a hook is integrally connected to the panel on the side facing the shell, the shell is provided with a slot for the hook to pass through, and a block cooperating with the hook is integrally connected to one side of the shell.

[0008] By adopting the above technical solution, after the panel moves toward the shell, the panel drives the hook to move until the hook passes through the slot and the hook is engaged with the card block.

[0009] As a further solution of the utility model: an indicator plate is integrally connected to one side of the shell, the indicator plate is provided with a third through slot penetrating the indicator plate, and the indicator plate is clamped with a clamping plate via the third through slot.

[0010] By adopting the above technical solution, the setting of the indicator board plays an indicating role.

[0011] As a further solution of the utility model: a plurality of friction lines are arranged on one side of the panel.

[0012] By adopting the above technical solution, the setting of the friction pattern increases the friction force on one side of the panel.

[0013] As a further solution of the utility model: a placement groove recessed inwardly is provided on one side of the shell.

[0014] By adopting the above technical solution, the electronic components can be placed in the placement groove.

[0015] As a further solution of the utility model: a first connecting column is integrally connected to one side of the shell, and a square plate is integrally connected to one end of the first connecting column away from the shell.

[0016] By adopting the above technical solution, the square plate is arranged to be convenient for hand holding.

[0017] As a further solution of the utility model: one end of the shell is provided with a first threading groove penetrating the shell, and the shell is provided with a second threading groove communicating with the placement groove.

[0018] By adopting the above technical solution, the first threading groove and the second threading groove provide connection channels for external electronic components.

[0019] As a further solution of the utility model: a ventilation hole is provided in the middle of the shell.

[0020] By adopting the above technical solution, the heat dissipation inside the shell is increased.

[0021] As a further solution of the utility model: a gasket is provided on one side of the limiting ring.

[0022] By adopting the above technical solution, the provision of the gasket increases the contact area between the limiting ring and the limiting plate.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] Since the limit rod is in the limit groove of the limit plate and cannot rotate, the rotary rod will also be unable to rotate and the rotary cover cannot be rotated. Therefore, when the rotary cover is accidentally touched, the rotary cover cannot be rotated. When the rotary cover needs to be rotated, it is necessary to press the rotary cover to drive the rotary rod to move inward and then drive the limit rod to move inward. When the limit rod moves out of the limit groove, the rotary cover can be rotated. When there is no external force, the spring applies an outward force to the rotary cover, and a part of the limit ring is in the limit groove. Therefore, the setting of the limit ring can prevent the rotary rod from passing through the first through groove. BRIEF DESCRIPTION OF THE DRAWINGS
