Wherein the first end 121 is used to abut against the guide 13, thereby restricting displacement of the guide 13 in the axial direction of the link 122; the second end 123 is used for connecting the base 11, so that the fixing member 12 is connected to the base 11; the link 122 is generally cylindrical, so that the guide 13 can be sleeved on the link 122 and can rotate relative to the link 122. Meanwhile, the fixing member 12 further has a mounting hole 124, the mounting hole 124 is coaxial with the through hole 111 and the connecting rod 122, and the mounting hole 124 penetrates through the first end 121, the connecting rod 122 and the second end 123.

Referring to fig. 3, in order to ensure that the guide 13 sleeved on the link 122 does not disengage from the link 122 from the first end 121 and to limit the displacement of the guide 13 in the axial direction of the link 122, so that the guide 13 only has a rotational degree of freedom along the axis of the link 122, the first end 121 may protrude from the link 122 in the radial direction of the link 122, and the first end 121 is used for abutting the guide 13 against the base 11. Meanwhile, referring to fig. 4, the first end 121 may have a first guide surface 1211 disposed toward the guide member 13, the first guide surface 1211 is disposed around an axis of the connecting rod 122, and the first guide surface 1211 is disposed in an inclined manner with respect to an axis direction of the mounting hole 124, that is, the first guide surface 1211 is not parallel to the axis of the mounting hole 124 and is not perpendicular to the axis of the mounting hole 124. A side of the first guide surface 1211 that is closer to the link 122 may be closer to the second end 123 than a side of the first guide surface 1211 that is farther from the link 122.
Referring to fig. 3 and fig. 5, the guiding element 13 is provided with a sleeve hole 134, and the connecting rod 122 is disposed through the sleeve hole 134, that is, the guiding element 13 is sleeved on the connecting rod 122. In this embodiment, when the guide 13 is sleeved on the connecting rod 122 and rotates relative to the connecting rod 122, in order to avoid a situation that the connecting rod 122 and the guide 13 may interfere with each other to form friction, so that the guide 13 cannot rotate relative to the connecting rod 122, the inner wall of the guide 13 located in the sleeving hole 134 and the outer wall of the connecting rod 122 may be separated from each other, that is, the inner diameter of the sleeving hole 134 is greater than the outer diameter of the connecting rod 122, so as to avoid contact between the inner wall of the guide 13 located in the sleeving hole 134 and the outer wall of the connecting rod 122. Furthermore, on the surface of the guide 13 away from the base 11, the edge away from the link 122 is provided with a first bevel 135, and the first bevel 135 may be a smoother chamfer.
In this embodiment, in order to ensure that the axis of the connecting rod 122 coincides with the axis of the sleeve hole 134 when the connecting rod 122 is inserted into the sleeve hole 134, the guiding element 13 is provided with a second guiding surface 133, the second guiding surface 133 is disposed around the axis of the sleeve hole 134, and the second guiding surface 133 is used for matching with the first guiding surface 1211 and attaching to the first guiding surface 1211. Of course, in order for the second guiding surface 133 to be able to abut against the first guiding surface 1211, the second guiding surface 133 may be similar to the first guiding surface 1211, i.e., a side of the second guiding surface 133 close to the axis of the connecting rod 122 is closer to the second end 123 than a side of the second guiding surface 133 away from the axis of the connecting rod 122, so as to ensure that the axis of the connecting rod 122 coincides with the axis of the sleeve hole 134.

In addition, in order to avoid that the first guide surface 1211 and the second guide surface 133 have a large friction when being attached to each other, so that it is difficult for the guide member 13 to rotate relative to the fixing member 12, both the first guide surface 1211 and the second guide surface 133 may be a relatively smooth curved surface, or a surface formed by splicing two or more relatively smooth flat surfaces or curved surfaces, which is not limited herein. When the first guide surface 1211 and the second guide surface 133 are smooth, that is, the surface roughness of the first guide surface 1211 and the second guide surface 133 is small, under the same conditions, the friction coefficient between the first guide surface 1211 and the second guide surface 133 is small, so that the friction force between the first guide surface 1211 and the second guide surface 133 is small, and the first end 121 does not easily restrict the rotation of the guide member 13 when the guide member 13 rotates. Meanwhile, when the surface roughness of the first guide surface 1211 and the second guide surface 133 is small, the wear resistance of the first guide surface 1211 and the second guide surface 133 is good, that is, when the first guide surface 1211 and the second guide surface 133 slide with each other, the friction loss of the first guide surface 1211 and the second guide surface 133 is small, so that the service life can be prolonged.
Referring to fig. 3 again, the guide 13 is disposed between the first end 121 and the base 11, in order to better achieve the purpose that the guide 13 can hover at any position after rotating, in this embodiment, a gap 112 is formed between the guide 13 and the base 11, so as to avoid friction caused by interference between the guide 13 and the base 11, and meanwhile, a damping member 15 may be disposed between the guide 13 and the base 11, where the damping member 15 is clamped between the guide 13 and the base 11, that is, the damping member 15 abuts against both the guide 13 and the base 11. When the guide 13 rotates, friction exists between the guide 13 and the damping piece 15, so that the rotating speed of the guide 13 can be reduced, and when the guide 13 stops rotating, the damping piece 15 can also limit the rotation of the guide 13, so that the guide 13 can hover when the rotation stops, namely the requirement that the guide 13 hovers at any position is met.

When the guiding element 13 rotates, the silicone ring may receive the torque of the guiding element 13 and the base 11 around the axis of the connecting rod 122 at the same time, and the direction of the torque applied to the silicone ring by the guiding element 13 and the base 11 is opposite, so that the silicone ring may deform, thereby changing the position relationship of the silicone ring between the guiding element 13 and the base 11, referring to fig. 2, fig. 3, and fig. 5, an installation groove 131 may be formed on at least one of the surface of the guiding element 13 facing the base 11 and the surface of the base 11 facing the guiding element 13, the silicone ring is at least partially embedded in the installation groove 131, and a portion of the silicone ring embedded in the installation groove 131 is attached to the inner wall of the installation groove 131. When the guide piece 13 rotates and makes the silica gel circle have the trend that produces deformation, the deformation of silica gel circle is restricted to the inner wall of mounting groove 131 to keep the position and the shape of silica gel circle, and then realize that the silica gel circle realizes that guide piece 13 hovers in the optional position purpose.
In other embodiments, the guide 13 and the base 11 may not be provided with the mounting groove 131, the damping member 15 may be a silicone sheet, the silicone sheet is sleeved on the connecting rod 122 and clamped in the gap 112 between the guide 13 and the base 11, the silicone sheet has two opposite side surfaces, one side surface is attached to the surface of the guide 13 facing the base 11, and the other side surface is attached to the surface of the base 11 facing the guide 13.

Referring to fig. 2, 5 and 6, the silicone ring may be divided into a first half ring 151 and a second half ring 152, the cross section of the first half ring 151 and the cross section of the second half ring 152 are substantially the same as a semicircle, the first half ring 151 of the silicone ring may be at least partially embedded into the first mounting groove 132, the second half ring 152 of the silicone ring may be at least partially embedded into the second mounting groove 116, that is, the silicone ring may be simultaneously embedded into the first mounting groove 132 and the second mounting groove 116, the portion of the silicone ring embedded into the first mounting groove 132 is attached to the inner wall of the first mounting groove 132, and the portion of the silicone ring embedded into the second mounting groove 116 is attached to the inner wall of the second mounting groove 116. In addition, the part of the first half 151 of the silicone ring that is not fitted into the first fitting groove 132 and the part of the second half 152 of the silicone ring that is not fitted into the second fitting groove 116 are both located in the gap 112 between the guide 13 and the base 11. When the guide member 13 rotates, the first mounting groove 132 and the second mounting groove 116 limit deformation of the silicone ring together to keep the position and shape of the silicone ring as much as possible, thereby preventing the silicone ring from failing.
In other embodiments, the first mounting groove 132 may be formed only on the surface of the guide 13 facing the base 11, and the first half-circle 151 of the silicone ring and a portion of the second half-circle 152 of the silicone ring are embedded in the first mounting groove 132, so that the deformation of the silicone ring is limited by the first mounting groove 132.

The first connecting member 30 is disposed through the door, and two ends of the first connecting member 30 respectively protrude from an inner side surface of the door and an outer side surface of the door, wherein one end of the first connecting member 30 protruding from the inner side surface of the door is connected to the first lock body 20, and the other end of the first connecting member 30 is disposed through the mounting hole 124 and connected to the first end 121, i.e., the positioning device 10 and the first lock body 20 are connected through the first connecting member 30. When the positioning element 14 is connected to the first lock body 20, the guiding element 13 can rotate around the connecting rod 122, that is, the guiding element 13 rotates around the first connecting element 30, so that the guiding element 13 and the positioning element 14 rotate around the axis of the first connecting element 30 relative to the first lock body 20.
Of course, in other embodiments, the first lock body 20 may be disposed on the inner side of the door, and the second lock body 40 and the positioning device 10 may be disposed on the outer side of the door.
Referring to fig. 8 and 9, in the present embodiment, the edge of the second lock body 40 located in the positioning hole 41 is provided with a third bevel 42, the third bevel 42 is a substantially smooth chamfer similar to the first bevel 135, and the third bevel 42 and the first bevel 135 can cooperate with each other, after the positioning device 10 is installed on the outer side surface of the door, the second lock body 40 can be substantially located at the position where the positioning hole 41 and the positioning device 10 can cooperate with each other and gradually approach to the outer side surface of the door, the edge of the positioning member 13 and the positioning member 14 of the positioning device 10 will abut against the edge of the positioning hole 41, when the second lock body 40 continues to approach to the outer side surface of the door, the third bevel 42 and the first bevel 135 cooperate with each other, so that the third bevel 42 can slide along the first bevel 135, so that the second lock body 40 slides to the position where the positioning hole 41 can accommodate the guiding members 13 and 14, and when the second lock body 40 continues to approach to the outer side surfaces, the guiding member 13 and the positioning member 14 are gradually accommodated in the positioning hole 41 and are attached to at least partially attached to the inner wall of the positioning hole 41.
In other embodiments, positioning device 10 may have a first rounded corner instead of first bevel 135, and second lock 40 may have a second rounded corner instead of third bevel 42, where the second rounded corner may slide along the first rounded corner, so as to reach a position where second lock 40 slides into positioning hole 41 to accommodate guiding element 13 and positioning element 14. Or positioning device 10 may not be provided with first bevel 135 and second lock body 40 may not be provided with third bevel 42, and positioning device 10 may be accommodated in positioning hole 41 of second lock body 40 through a larger number of attempts.
Referring to fig. 7 and 9, in the present embodiment, the bottom wall of the second lock body 40 located at the positioning hole 41 may protrude toward the opening of the positioning hole 41 to form a fastening position 44 (when viewed from the outer side of the second lock body, the fastening position 44 is formed by inward recessing of the outer side of the second lock body), the fastening position 44 corresponds to the first assembling hole 148 and the second assembling hole 149, when the positioning device 10 is received in the positioning hole 41, the fastening member 60 may be disposed at the fastening position 44, one end of the fastening member 60 is connected to the second lock body 40, and the other end is inserted into the positioning hole 41 and the first assembling hole 148/the second assembling hole 149 and connected to the positioning member 14, so that the second lock body 40 and the positioning device 10 are fixedly connected and can form a relative whole, thereby preventing an error from occurring when the second lock body 40 follows the guide member 13 and the positioning member 14 and rotates relative to the first lock body 20, that is an error that occurs after the first lock body 20 and the second lock body 40 are connected by the second connecting member 50, the first lock body 20 and the second lock body 40 cannot be accurately positioned at the position for disposing the third connecting member 70. That is, after the second lock body 40 is connected to the positioning device 10 by the fastening member 60, the position relationship between one end of the second lock body 40 and one end of the first lock body 20 connected to the positioning device 10 is determined, after the second lock body 40 follows the guide member 13 and the positioning member 14 is rotated to the corresponding position, the second connecting member 50 can connect the second lock body 40 and the first lock body 20, the position relationship between the second lock body 40 and the first lock body 20 is determined, and the portion of the second lock body 40 for disposing the third connecting member 70 corresponds to the portion of the first lock body 20 for disposing the third connecting member 70.
In a more specific embodiment, the number of the fastening locations 44 and the number of the fastening members 60 may be two, when the positioning device 10 is received in the positioning hole 41, the two fastening members 44 are respectively opposite to the first assembling holes 148 and the second assembling holes 149, the two fastening members 44 are respectively disposed on the two fastening locations 44, and one ends of the two fastening members 44 are respectively connected to the second lock body 40, wherein the other end of one fastening member 44 extends into the first assembling hole 148 and is connected to the inner wall of the first assembling hole 148, and the other end of the other fastening member 44 extends into the second assembling hole 149 and is connected to the inner wall of the second assembling hole 149, so that the positioning device 10 and the second lock body 40 are relatively fixed. When the fastener 60 is used to connect the second lock body 40 and the positioning member 14, the positioning member 14 and the side of the guiding member 13 close to the positioning member 14 are subjected to a tension force toward the second lock body 40, and at this time, since the contact surfaces (i.e., the first guiding surface 1211 and the second guiding surface 133) between the first end 121 and the guiding member 13 are obliquely arranged, the first guiding surface 1211 of the first end 121 can always abut against the second guiding surface 133 of the guiding member 13, so as to prevent the guiding member 13 and the positioning member 14 from being inclined.
In order to prevent the door from being deformed slightly, when the positioning device 10 is accommodated in the positioning hole 41, one end of the positioning device 10 away from the door abuts against the second lock body 40, so that a gap is formed between the second lock body 40 and the surface of the door, please refer to fig. 10, in this embodiment, a space 43 may be formed between the bottom wall of the second lock body 40 forming the positioning hole 41 and the positioning device 10. When the door is slightly deformed, the positioning device 10 is closer to the bottom wall of the second lock body 40 forming the positioning hole 41 than when the door is not deformed, and the space 43 can be tolerant to the bottom wall of the second lock body 40 located at the positioning hole 41 and the positioning device 10, that is, due to the existence of the space 43, even if the positioning device 10 is closer to the bottom wall of the second lock body 40 forming the positioning hole 41, a gap does not occur between the second lock body 40 and the door.
The installation principle of the lockset 100 provided by the invention is as follows: the positioning device 10 and the first lock body 20 are respectively arranged at two sides of the door, and the positioning device 10 is connected with the first lock body 20 through the first connecting piece 30, so that the overall position between the positioning device 10 and the first lock body 20 is relatively fixed. After the guide 13 and the positioning member 14 are manually rotated to a certain position, due to the limiting effect of the damping member 15, the guide 13 and the positioning member 14 are suspended at the position when the manual rotation of the guide 13 and the positioning member 14 is lost.
After the positioning hole 41 of the second lock body 40 is approximately aligned with the positioning device 10, the second lock body 40 is moved toward the positioning device 10 until the guiding member 13 and the positioning member 14 abut against the edge of the second lock body 40 located at the positioning hole 41, and the third bevel 42 slides along the first bevel 135 and the second bevel 141, so that the second lock body 40 is moved to a position where the positioning hole 41 can accommodate the positioning device 10, at this time, the second lock body 40 is continuously moved until the positioning hole 41 completely accommodates the positioning device 10 and the second lock body 40 abuts against the surface of the door, and the second lock body 40 and the positioning member 14 are fixedly connected by the fastening member 60, so that the position between the second lock body 40 and the positioning device 10 is relatively fixed. Compared with the push-pull intelligent door lock in the prior art, in the intelligent door lock provided by the embodiment of the invention, the position (namely the position of the mounting hole 124) of the original mounting paired lock screw can be kept unchanged so as to meet the national standard; meanwhile, the fastening position 44 and the mounting hole 124 are staggered, so that the mounting position of the fastening piece 60 and the mounting position of the push handle are staggered, the mounting of the fastening piece and the mounting position of the push handle are not affected by each other, the push handle does not need to be set in a side fixing mode, and the push handle can meet the strength requirement.
After the second lock body 40 is rotated to a position where the second lock body 20 can be connected to the first lock body 20 through the first connecting member 30, and the first connecting member 30 connects the first lock body 20 to the second lock body 40, the position of the first lock body 20 where the third connecting member 70 is disposed is opposite to the position of the second lock body 40 where the third connecting member 70 is disposed, and then the third connecting member 70 is installed, thereby completing the fixing between the first lock body 20 and the second lock body 40.
The positioning device 10 provided by the invention can be suitable for various intelligent door locks, such as handle locks or push-pull locks, and the like, and can also be arranged in doors or outside the doors, thereby enriching the selectivity of the intelligent door locks during installation. And in the positioning device 10, the guide part 13 and the positioning part 14 can rotate at will and can hover after rotating, thereby meeting other operation requirements and improving the convenience of installation.
According to the lock 100 provided by the invention, when the edges of the guide member 13 and the positioning member 14 abut against the edge of the positioning hole 41 of the second lock body 40, the second lock body 40 can slide to the position where the positioning hole 41 can accommodate the positioning device 10, so that the second lock body 40 has an automatic guiding function when being installed, the positioning hole 41 and the positioning device 10 can be aligned without many attempts, and the operation is simple and rapid. Meanwhile, a gap 43 exists between the bottom wall of the second lock body 40 located in the positioning hole 41 and the positioning device 10, so that a fault-tolerant function is achieved when the door is slightly deformed, and the installation environment of the lock 100 is improved.
