Aiming at the problem that in the prior art, a hook wheel in an electric door lock can not be connected with the hook wheel due to the fact that the hook wheel is turned over by mistake, the application provides a door hook connecting mechanism, and the problem that the hook wheel is turned over by mistake can be solved by adopting the door hook connecting mechanism.
As shown in fig. 1 to 3, the door hook connection mechanism 1 includes:
a mounting case 11;
a rotating shaft 12, the rotating shaft 12 being connected to the mounting housing 11;
the hook wheel 13, the hook wheel 13 is rotatably connected to the installation shell 11 through the rotating shaft 12, and a hooking part 133 capable of hooking the door hook 200 through rotation is arranged on the hook wheel 13 so as to realize the connection with the door hook 200;
an elastic member 14, the elastic member 14 is configured to apply elastic force to the hook wheel 13.
Wherein, at least one of the mounting shell 11 and the hook wheel 13 is provided with a sliding hole with a preset extending track for mounting the rotating shaft 12, the rotating shaft 12 is arranged to be capable of moving along the sliding hole so that the hook wheel 13 can move along the sliding hole relative to the mounting shell 11, wherein, the movement along the sliding hole refers to the movement along the extending track of the sliding hole, and the extending track can be a straight line (i.e. the sliding hole is a long hole), an arc line (i.e. the sliding hole is an arc hole) or other curved shapes.
When the hook wheel 13 is not connected with the door hook 200, the hook wheel 13 is provided to have a first state (a state shown in fig. 2) in which the hook wheel 13 can be pushed to be turned over to be connected with the door hook 200 (i.e., the hooking portion 133 is turned over to hook the door hook 200) when the door hook 200 moves toward the hook wheel 13 and can be rotated from the first state to a second state (a state shown in fig. 3); in the second state, the movement of the door hook 200 toward the hook wheel 13 can push the hook wheel 13 to move along the sliding hole, when the door hook 200 moves to the preset position, the door hook 200 is snapped into the hooking portion 133 (as in the embodiment shown in fig. 3, when the door hook 200 moves to the end of the hooking portion 133, the door hook is snapped into the inside from the outside of the end, and enters the door hook locking interface 132), and the elastic force applied by the elastic member 14 makes the hook wheel 13 move reversely, so that the door hook 200 further enters the door hook locking interface 132. In this way, the hooking portion 133 of the hook wheel 13 hooks the hook wheel 200, when the hook wheel 200 is pulled out, the hook wheel 200 can be made to rotate the hook wheel 13, so that the hook wheel 13 is rotated to the first state, and then when the hook wheel 200 is moved again to be connected with the hook wheel connecting mechanism 1, the hook wheel 13 in the first state can be normally pushed by the hook wheel 200, so that the hook wheel 13 is rotated from the first state to be connected with the hook wheel 200.
That is, the first state is a normal operation state when the hook wheel 13 is not connected to the door hook 200, and the second state is an abnormal operation state (possibly a child uses a toy to turn the hook wheel 13 by mistake or other reasons to turn the hook wheel 13 to the second state) when the hook wheel 13 is not connected to the door hook 200, by causing the door hook 200 to push the hook wheel 13 in the second state to move along the sliding hole, then the door hook 200 enters the hooking portion 133 of the hook wheel 13, so that the hooking portion 133 hooks the door hook 200, and then the hook wheel 13 can be driven to rotate when the door hook 200 is pulled outward, thereby causing the hook wheel 13 to return from the abnormal second state to the normal first state. Thereafter, the door hook 200 can be normally coupled to and decoupled from the hook wheel 13. Therefore, the technical scheme provided by the application can solve the problem that the door hook cannot be connected with the hook wheel due to the fact that the hook wheel is overturned by mistake in the prior art.
The technical scheme provided by the application is described in detail below according to the specific embodiment.
In one embodiment, as shown in fig. 2 and 3, and in combination with fig. 5 and 6, the mounting housing 11 shown in fig. 2 and 3 is a structure in which the mounting housing 11 in fig. 1 is longitudinally cut from a position where the hook wheel 13 is mounted, the mounting housing 11 is provided with a first stopper 114 and a second stopper 115, and the hook wheel 13 is provided with a first contact 135 and a second contact 136.
In the first state, the first contact portion 135 rests against the first stop portion 114, such that the hook wheel 13 is maintained in the first state, and when the hook wheel 13 is rotated to the second state, the second contact portion 136 rests against the second stop portion 115, such that the hook wheel 13 is maintained in the second state. Wherein, the second stop portion 115 is provided with a sliding surface along which the second contact portion 136 moves during the process that the hook 200 pushes the hook wheel 13 to move along the sliding hole relative to the mounting housing 11, that is, the extending track of the sliding hole is consistent with the extending track of the sliding surface. As shown in fig. 3, the hook wheel 13 is moved in a straight direction indicated by an arrow against the sliding surface during the movement of the hook wheel 13 along the straight sliding hole. It will be appreciated that where the sliding aperture is an arcuate aperture having an arcuate extension path or an aperture having a path of other shape, the sliding surface has an arcuate extension path or an extension path of other shape.
In this embodiment, optionally, in the first state, the surface on the first contact portion 135 and the surface on the first stop portion 114 abut together, that is, the first contact portion 135 and the first stop portion 114 are in surface-to-surface contact, so that the first contact portion 135 rests stably on the first stop portion 114;
alternatively, in the second state, a point or line on the second contact 136 is in contact with the second stop 115, and the second contact 136 is in point-to-surface contact or line-to-surface contact with the sliding surface during movement of the hook wheel 13 relative to the mounting housing 11 along the sliding aperture. In this way, the friction force when the second contact portion 136 moves along the second stopper portion 115 is small, so that the hook wheel 13 can easily move along the slide hole with respect to the mounting housing 11.
In one embodiment, the mounting housing 11 is provided with a first sliding hole 111, the hook wheel 13 is provided with a second sliding hole 131, and the rotating shaft 12 is mounted through the first sliding hole 111 and the second sliding hole 131. Fig. 5 shows that first sliding holes 111 are respectively provided at both sides of the installation housing 11, both ends of the rotating shaft 12 are respectively penetrated through the first sliding holes 111 at both sides, and the middle part of the rotating shaft 12 is penetrated through the second sliding holes 131 of the hook wheel 13.
Wherein, when the hook wheel 13 is in the second state, the extending tracks of the first sliding hole 111 and the second sliding hole 131 are in butt joint, so that the hook wheel 13 can move along the extending tracks of the second sliding hole 131 and the first sliding hole 111 in sequence relative to the mounting housing 11. Thus, the movement stroke of the hook wheel 13 with respect to the mounting case 11 is approximately the sum of the extension track lengths of both the second slide hole 131 and the first slide hole 111. That is, providing the slide holes on the hook wheel 13 and the mounting housing 11, respectively, can facilitate increasing the moving stroke of the hook wheel 13 with respect to the mounting housing 11. As shown in fig. 3 and 4, when the hook wheel 13 is in the second state, the extended trajectories of the first sliding hole 111 and the second sliding hole 131 are butted, both of which are straight extended trajectories, and when the door hook 200 pushes the hook wheel 13 to move along the arrow indicated in fig. 3, the hook wheel 13 first moves along the extended trajectory of the second sliding hole 131 and then moves along the extended trajectory of the first sliding hole 111.
Of course, in the case where a large movement stroke is not required, only the slide hole may be provided in the hook wheel 13, or only the slide hole may be provided in the mounting case 11, and the hook wheel 13 may be moved along the slide hole with respect to the mounting case 11.
In one embodiment, the hook wheel 13 is as shown in fig. 5 (in combination with fig. 2 and 3), the hook wheel 13 is provided with a door hook inlet 132, two sides of the door hook inlet 132 are respectively provided with a first side and a second side, and the door hook 200 moves towards the hook wheel and is firstly close to the second side; wherein the second side portion is formed as the hooking portion 133; the first side is provided with a first bevel 137 facing the second side and the second side is provided with a second bevel 138 facing away from the first side.
Wherein, when the hook wheel 13 is in the first state, as shown in fig. 2, the door hook 200 makes the hooking portion 133 of the hook wheel 13 hook the door hook 200 by pushing the first inclined surface 137 to rotate the hook wheel 13 during the movement of the door hook 200 toward the hook wheel 13; when the hook wheel 13 is in the second state, as shown in fig. 3, the hook wheel 13 moves along the sliding hole by pushing the second inclined surface 138 during the movement of the hook wheel 200 toward the hook wheel 13, and when moving to a certain position, the hook wheel 200 is snapped into the hooking portion 133 from the second side into the hook clip inlet 132, and then the hook wheel 13 moves reversely, so that the hook wheel 200 further enters the hook clip inlet 132.
In one embodiment, the elastic member 14 for applying elastic force to the hook wheel 13 is a torsion spring, one torsion arm of which is connected to the mounting housing 11, and the other torsion arm of which is connected to the hook wheel 13. As shown in fig. 3, one torsion arm of the elastic member 14 is connected to a torsion arm mounting portion 113 provided on the mounting housing 11, and the other torsion arm is connected to a torsion arm mounting hole 139 of the hook wheel 13.
Since the torsion spring moves along with the hook wheel 13 during the movement of the hook wheel 13 along the sliding hole relative to the mounting housing 11, in order to ensure that the torsion spring can stably apply elastic force to the hook wheel 13, the mounting housing 11 is provided with side limiting surfaces 112 positioned at opposite sides of the torsion spring, as shown in fig. 6 (the space between the two side limiting surfaces 112 is used for mounting the torsion spring), and both sides of the torsion spring can stably move along with the hook wheel 13 through the limitation of the side limiting surfaces 112.
In one embodiment, the mounting housing 11 may be an integrally formed structure, and in another embodiment, the mounting housing 11 includes a housing body and a housing block 116 (see fig. 10) mounted on the housing body, and the sliding hole is provided on the housing block 116. The manner of dividing the mounting housing 11 into the housing body and the housing block 116 can be easily manufactured, and the housing body and the housing block 116 can be provided as different materials, which is advantageous in saving costs. Alternatively, the housing body is made of plastic, and the housing block 116 is made of a plastic material harder than the housing body or made of metal, so that the mounting of the shaft on the housing block 116 is more stable.
The mounting housing 11 shown in fig. 2, 3 and 6 may be a part of a lock housing of a door lock, and the lock housing of the door lock may be made in a plurality of parts or may be formed as a single body, and it is understood that the lock housing may be variously modified as needed without limitation.
In one embodiment, as shown in fig. 9, the lock case 3 of the door lock includes a first case 31 and a second case 32, and in this embodiment, the mounting case 11 to which the hook wheel 13 is mounted is the second case 32 of the lock case 3.
In the embodiment shown in fig. 10, the housing block 116 for mounting the wheel axle 12 is fixed to the second housing 32, i.e., the mounting housing 11 is a structure in which the second housing 32 and the housing block 116 are assembled.

When the door hook 200 does not enter the locking notch 34 provided on the lock case 3 of the door lock main body 100, the spring 22 presses the lock slider 21 (the end having the pressing block 212) against the unlocking surface of the hook wheel 13 (the state shown in fig. 1), so that the lock slider 21 is kept at the first position by the spring 22 and the hook wheel 13, after the door hook 200 enters the locking notch 34, the hook wheel 13 rotates to catch the door hook 200 and drives the lock slider 21 to act during rotation, the pressing block 22 is pressed and moved to the second position, and when the lock slider 21 is at the second position, the pressing block 212 at the end of the lock slider 21 presses against the locking surface 134 of the hook wheel 13 (the state shown in fig. 13), that is, the spring 22 and the hook wheel 13 keep the lock slider 21 at the second position, and then the driving mechanism 24 drives the locking piece 23 to switch to the locking position, so that the lock slider 21 is locked at the second position (that is, the locking mechanism 2 is switched to the locking state), and thus the hook wheel 13 can be prevented from being turned over, and the hook 200 is prevented from being separated from the hook wheel 13. When the driving mechanism 24 drives the locking piece 23 to switch to the unlocking position (i.e., the locking mechanism 2 switches to the unlocking state), the locking slider 21 is disengaged from the locking of the locking piece 23, and when the door hook 200 is disengaged from the hook wheel 13, the rotation of the hook wheel 13 can cause the locking slider 21 to move from the second position to the first position.
To enable the locking member 23 to lock the locking slider 21 in the second position and unlock it from the second position, in one embodiment, as shown in fig. 1 and 11, a locking groove 211 is provided on the locking slider 21, a locking block 231 cooperating with the locking groove 211 is provided on the locking member 23, the locking member 23 further includes a chute 232 (refer to fig. 11 and in combination with fig. 12) provided obliquely, the driving mechanism 24 includes a driving rod 241 capable of moving in the chute 232, and after the driving mechanism 24 receives a first pulse signal (for example, a pulse signal given when the electric appliance is started), the driving mechanism 24 acts such that the driving rod 241 moves to a first preset position in the chute 232 and drives the locking member 23 to a locking position through the chute 232, and the locking block 231 of the locking member 23 is inserted into the locking groove 211 to lock the locking slider 21 in the second position, as shown in fig. 11. Fig. 12 shows that the sliding groove 232 is obliquely arranged, and the driving rod 241 is arranged to move up and down, so that the locking member 23 is driven to move by the sliding groove 232 during the up and down movement of the driving rod 241.
After receiving the second pulse signal (for example, the pulse signal given when the electric appliance stops working), the driving mechanism 24 acts, so that the driving rod 241 moves to the second preset position in the sliding groove 232 and drives the locking piece 23 to move to the unlocking position through the sliding groove 232, the locking block 231 is separated from the locking groove 211, the locking sliding block 21 is released, and the door hook 200 can be separated from the hook wheel 13.
In this embodiment, the lock mechanism 24 and the lock member 23 are provided in the electric box 33, and fig. 12 shows a state in which the electric box 33 is separated into the electric box main body 331 and the box cover 332 to show the connection relationship of the drive mechanism 24 and the lock member 23.
The specific structure of the driving mechanism 24 and other structures in the door lock are not important to the present application, and the driving mechanism 24 is a technology that can be implemented in the door lock by those skilled in the art, and will not be described in detail herein.
