Description

Technical Field

[0001] This utility model relates to the field of smart door locks, and in particular to a latch limiting handle structure and a smart door lock using the structure. Background Technology

[0002] Smart door locks, especially fully automatic locks, often have a pull handle, but this can easily obstruct the keyhole. Common solutions include: 1. Making a through hole directly in the handle and adding a plug. This is cumbersome because even if the appearance is damaged, at least two plugs need to be opened to unlock with a mechanical key. 2. Setting the handle to have a rotating structure, such as rotating after pulling it outwards or pushing it up or down. This solution is complex, and to ensure minimal wobbling, a large energy storage spring is often used in the axial or vertical movement direction of the handle, resulting in a large operating force and making it impractical. Therefore, a latching and limiting handle structure and a smart door lock using this structure are proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a latching limit handle structure and an intelligent door lock using the structure, aiming to improve the problems of existing technologies where directly opening a through hole on the handle will damage the appearance of the door lock and make the unlocking operation complicated, and where the handle is designed with a rotatable structure, which is complex and requires a large operating force.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a latching and limiting handle structure, including a latching post, wherein a latching groove is provided in the middle of the latching post, and a retaining spring is engaged in the latching groove.

[0013] The lower part of the limiting plate has a wire hole, and the middle part of the limiting plate has two screw holes of number two. The bolt is movably connected to the screw holes of number two.

[0014] As a further description of the above technical solution:

[0015] The cylindrical shaft has a first screw hole in the middle, and the bolt is movably connected to the first screw hole. The lower part of the cylindrical shaft has a wire groove, and the wire groove is positioned corresponding to the wire hole.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a latch is set at the radial position of the rotation center of the door lock handle to lock the panel and the handle, thereby locking the handle by rotation. When the handle needs to be rotated, the latch is pulled out of the radial hole of the handle shaft to disengage it from the locking hole, and the handle can be rotated to the left or right to expose the lock head cover for mechanical key unlocking. The above structure not only ensures the overall appearance of the handle, but also makes it simple and reliable to operate and highly practical. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 4 - Figure 5The present invention provides an embodiment of a latching and limiting handle structure, including a latching post 4 for limiting the handle, which has a slot 41 in the middle for connecting with a retaining spring 8. The retaining spring 8 is engaged in the slot 41 for axial positioning. A knurled block 42 is fixedly connected to the lower part of the latching post 4 to facilitate the pulling down operation of the latching post 4.

[0032] Refer to the image Figure 1 - Figure 3 As shown, this utility model also provides an embodiment: an intelligent door lock, which further includes a panel 1, which is the main component of the door lock. A door lock handle 2 is installed on the front side of the panel 1. An O-ring 6 is provided between the door lock handle 2 and the panel 1 to increase the pre-tightening force between the door lock handle 2 and the panel 1 and to provide a rotating feel. A limit plate 3 is provided on the rear side of the panel 1. The door lock handle 2 and the limit plate 3 can be movably connected by bolts 9.

[0033] Furthermore, a mounting sleeve 13 is fixedly connected to the lower part of the panel 1 for mounting the door lock handle 2. A first bolt hole 14 is provided on the lower side of both the panel 1 and the mounting sleeve 13. The door lock handle 2 includes a cylindrical shaft 21 for connecting various components. The cylindrical shaft 21 is movably connected to the mounting sleeve 13. A second bolt hole 23 is provided at the lower part of the cylindrical shaft 21. The bolt post 4 is inserted into the second bolt hole 23 and the first bolt hole 14 for easy positioning of the door lock handle 2. A bolt spring 5 is fixedly connected between the lower part of the inner wall of the panel 1 and the lower side of the mounting sleeve 13 for pulling and resetting the bolt post 4. The bolt spring 5 is sleeved on the outside of the bolt post 4. A washer 7 is installed between the bolt post 4 and the mounting sleeve 13 for connecting the bolt post 4 and the panel 1.

[0034] Furthermore, a mechanical keyhole 11 is installed in the middle of the panel 1 for mechanical unlocking. A lock head cover 10 is provided in front of the mechanical keyhole 11 for protecting the mechanical keyhole 11. Two limit blocks 12 are fixedly connected to the lower rear side of the panel 1. The two limit blocks 12 are symmetrically arranged to limit the rotation angle of the door lock handle 2.

[0035] Please see Figure 8 The lower part of the limiting plate 3 has a wire hole 32 for wiring installation. The middle part of the limiting plate 3 has two screw holes 31, and the bolt 9 is movably connected to the screw holes 31.

[0036] like Figure 6 - Figure 7As shown, a screw hole 24 is provided in the middle of the cylindrical shaft 21. The bolt 9 is movably connected to the screw hole 24 to connect the limiting plate 3 and the door lock handle 2. A wire groove 25 is provided at the lower part of the cylindrical shaft 21 to facilitate the connection of the wire. The wire groove 25 corresponds to the wire hole 32. The screw hole 24 corresponds to the screw hole 31. An O-groove 22 is provided on the rear side of the door lock handle 2, which is adapted to the O-ring 6. The O-ring 6 is movably connected to the O-groove 22.

[0037] Working principle: When using the mechanical key to unlock the door, the user needs to pinch the knurled block 42 and pull the bolt 4 downwards. At this time, the bolt spring 5 will be compressed and deformed, and the bolt 4 will be pulled out of the second bolt hole 23. Then, the door handle 2 can be turned forcefully. The door handle 2 can rotate relative to the shaft hole of the panel 1. The O-ring 6 has a certain preload. When the door handle 2 rotates, the panel 1 has two limit blocks 12 on the left and right sides of the limit plate 3, which can limit the rotation angle of the door handle 2. When the door handle 2 rotates to a certain angle, the lock head cover 10 can be rotated out. Then, the lock head cover 10 can be opened, and the mechanical key insertion hole 11 will be exposed. The mechanical key can be inserted to unlock the door. When it is necessary to limit the handle, simply turn the door handle 2 back to its original position and then release the bolt 4. The bolt spring 5 will drive the bolt 4 to reset and insert it into the second bolt hole 23.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
