Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

In one embodiment, and with reference to figures 1-10, a door lock is disclosed, the door lock body including a panel 10, an

A handle 20, the handle 20 is rotatably connected to the panel 10;

a driving strap 30, one end of the driving strap 30 is pivoted with the handle 20 and can move along with the rotation of the handle 20;

the driving wheel 40 is pivoted at the other end of the driving sheet 30 and can rotate along with the movement of the driving sheet 30;

one end of the transmission rod 50 is inserted into the transmission wheel 40 and rotates along with the rotation of the transmission wheel 40;

the other end of the transmission rod 50 is inserted into the lock body 70 and is linked with the bolt 71 of the lock body 70 to extend and retract.

In this embodiment, various transmission structures transmit external force from the handle 20 to the lock body 70 and cause the locking tongue 71 of the lock body 70 to extend and retract to unlock. The used transmission structure comprises a transmission piece 30, a transmission wheel 40 and a transmission rod 50, external force acts on the handle 20 to enable the handle 20 to rotate, and rotary motion can be converted into translational motion between the handle 20 and the transmission piece 30, namely the handle 20 rotates to drive the transmission piece 30 to translate; the translational motion between the driving strap 30 and the driving wheel 40 can be converted into rotational motion, i.e. the translational driving strap 30 drives the driving wheel 40 to rotate; the rotating transmission wheel 40 further drives the transmission rod 50 connected with the transmission wheel to rotate; the transmission rod 50 is linked with the locking tongue 71 of the lock body 70 to make the locking tongue 71 extend and unlock. Regarding the structure and unlocking of the lock body 70, the prior art is generally the same as the form shown in fig. 7-10, that is, the lock body itself has a substantially identical structure, and is inserted into the lock body 70 through a transmission rod 50, the transmission rod 50 may be a square rod, and the rotation of the transmission rod 50 further drives the lock tongue 71 of the lock body 70 to extend and retract, so the lock body will not be described in detail. The key innovation of the utility model is mainly the transmission structure from the handle 20 to the lock body 70, and the transmission structure is also the part with the most design space and innovation space in the door lock industry. In this solution, the handle 20 is rotated by external force from different directions, so that the door lock can be easily opened. The door lock has the advantages of simple overall structure, high transmission efficiency and durability.

In a particular embodiment, the axis of rotation of the handle 20 is perpendicular to the panel 10. That is, the specific shape of the handle 20 can be varied, such as circular, bar, sphere, etc., without limitation, only if the rotation axis about which the handle 20 rotates is perpendicular to the panel 10. Of course, the handle 20 here may preferably be a twist-on knob, the handle 20 being arranged perpendicular to the panel 10. Specifically, the circular handle 20 may be inserted into a corresponding mounting hole of the panel 10, and then the fixing plate 21 is combined to axially fix the handle 20, so as to prevent the handle 20 from falling off or moving axially, so that the handle 20 can only rotate along an axis perpendicular to the panel 10. It is also convenient to rotate the handle 20 clockwise or counterclockwise to unlock the lock under the driving of external force.

Referring again to the drawings, in one embodiment, in order to convert the rotation of the handle 20 into the translation of the driving strap 30, it is preferable that one end of the driving strap 30 is pivoted to the handle 20 by a first pivot shaft 31, and the axis of the first pivot shaft 31 is parallel to but not collinear with the axis of rotation of the handle 20. The pivot structure enables the handle 20 and the driving plate 30 to rotate relative to each other to a certain extent without being completely locked. Additionally, the axis of the first pivot shaft 31 is parallel to but not collinear with the axis of the handle 20, so that when the handle 20 rotates, the first pivot shaft 31 can also rotate synchronously, and the driving plate 30 can also translate relatively while rotating relatively with the handle 20, specifically, it can move relatively upward as shown in fig. 3 or relatively downward as shown in fig. 5. Similarly, in this structure, when there is no external force, the rotation of the handle 20 can be driven by the upward or downward movement of the driving strap 30, and the structure is a bidirectional design, which can convert the rotation of the handle 20 into the translation of the driving strap 30, and can also convert the translation of the driving strap 30 into the rotation of the handle 20. If collinear, it means that the first pivot axis 31 is disposed at the center of rotation of the handle 20, so that no matter the handle 20 rotates clockwise or counterclockwise, only the relative rotation between the handle 20 and the driving strap 30 is achieved, and no translation of the driving strap 30 occurs. In addition, the driving strap 30 may preferably be an elongated strap, and the driving strap 30 is translated along a plane parallel to the panel 10 as the driving wheel 40 or the handle 20 rotates.

In one embodiment, the driving wheel 40 is rotatably connected to the panel 10, and the axis of rotation of the driving wheel 40 is perpendicular to the panel 10. The other end of the driving strap 30 is pivotally connected to the driving wheel 40 through a second pivot shaft 32, and the axis of the second pivot shaft 32 is parallel to but not collinear with the axis of the rotation of the driving wheel 40. The structural relationship between the driving strap 30 and the driving wheel 40 is similar to the structural relationship between the driving strap 30 and the handle 20, and is a structural design for mutual conversion between rotational motion and translational motion. The axis of the second pivot shaft 32 is parallel to but not collinear with the axis of the transmission wheel 40, so that when the transmission piece 30 moves up or down, the transmission wheel 40 is synchronously driven to rotate, and further the transmission rod 50 is driven to link with the lock of the lock body 70. Meanwhile, the rotation of the driving wheel 40 in different directions can also be converted into the upward movement or the downward movement of the driving strap 30.

In an embodiment, the driving wheel 40 is fixedly sleeved with a linkage plate 41 capable of rotating synchronously therewith, and the second pivot shaft 32 is vertically inserted into the linkage plate 41. That is, in order to facilitate the formation of the rotatable pivotal connection between the driving wheel 40 and the driving plate 30, a linkage plate 41 is fixedly sleeved on the driving wheel 40, and then the linkage plate 41 is pivoted with the driving plate 30, so as to realize the mutual rotational connection between the driving wheel 40 and the driving plate 30, and certainly, the mutual rotational connection between the driving wheel 40 and the driving plate 30 can also be directly pivoted at the edge of the driving wheel 40. In order to satisfy the above non-collinear relationship, the second pivot shaft 32 is vertically inserted through the edge of the linkage plate 41 so as to be deviated from the rotation axis as much as possible.

Finally, as a door lock, there is basically a reset mechanism so that when the external force is removed, the latch tongue 71 automatically extends out of the lock body 70. The reset mechanism can be arranged at any position of the transmission structure, for example, the reset mechanism can be arranged at the handle 20, when the external force is removed, the reset mechanism drives the handle 20 to reset, and the handle 20 drives the rest structures to reset. The driving device can also be arranged on the driving sheet 30, the driving wheel 40, the linkage sheet 41, the driving rod 50 and the like. Here, the preferred embodiment of the present invention is that a reset button spring 60 is provided outside the driving wheel 40 to reset the rotated driving wheel 40 to the initial position when the external force is removed. Specifically, as shown, the main portion of the torsion spring may be fixedly disposed, and the first end 61 and the second end 62 of the torsion spring may be kept as free ends, although the torsion spring is sleeved outside the transmission wheel 40, but the torsion spring may not be fixedly connected with the transmission wheel. Meanwhile, a pushing protrusion 42 may be disposed on the communicating piece, and the pushing protrusion 42 is located between the first end 61 and the second end 62, so that when the linking piece 41 rotates along with the driving wheel 40, the pushing protrusion 42 can synchronously push the first end 61 or the second end 62 to synchronously move, such as rotate 50 degrees clockwise or counterclockwise. When the external force is removed, the torsion spring returns, and the first end 61 or the second end 62 reversely pushes the pushing protrusion 42 to return to the initial position, so as to synchronously drive the driving wheel 40 and other structures to return. In addition, in order to limit the first end 61 or the second end 62 to stay at a specific position, a limiting structure may be provided for the first end 61 and the second end 62, respectively, or a limiting protrusion 63 may be fixedly provided on the panel 10 to limit the first end 61 and the second end 62 at the same time as shown in fig. 1.

In conclusion, the door lock disclosed in the scheme mainly comprises a panel, a handle, a transmission piece, a transmission wheel, a transmission rod and a lock body, when a rotary external force acts on the handle, the force can be transmitted to the lock body through the transmission plate, the transmission wheel and the transmission rod in sequence, and the transmission rod is enabled to be linked with the lock tongue of the lock body to unlock the lock. When the external force is removed, the driving wheel and even the whole door lock are driven to return to the initial state under the action of the reset button spring. The door lock has simple integral structure and high transmission efficiency.
