Patent Description:
In various product applications, a door lock is a critical part. A structure, an appearance, and a material of the door lock vary based on different application scenarios. An ordinary door lock usually has a lock cylinder made of a metal material, and the lock cylinder is fastened to a panel of a box body in a threaded connection manner. After an external key is manually rotated, the lock cylinder compresses a spring and then the lock is opened. After the key is released, the lock cylinder may be reset, and the panel restores to a closed state. Based on an anti-theft characteristic and operation convenience of the door lock, the lock usually has a relatively complex structure and relatively high costs. For another door lock, a lock cylinder is driven to rotate through rotation of a key, and a barrier plate of the lock cylinder is detached from a fixing point, thereby achieving an unlocking function. Rotation of the lock cylinder needs to be driven by using the key, and the lock cylinder cannot automatically rebound. <CIT> discloses a garbage container contains a clamping portion (<NUM>) and a lock cylinder (<NUM>), wherein the lock cylinder comprises a shaft body and a guiding head (<NUM>).

To make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

<FIG> show an apparatus having a door lock assembly according to an embodiment of the present invention. <FIG> is a three-dimensional diagram of the apparatus, <FIG> is a front view of the apparatus, and <FIG> is a left view of the apparatus. The apparatus may be a communications device such as an access terminal box, or may be an accommodating box, an office cabinet, a safe, or the like. Examples are not listed one by one. The apparatus includes a first panel <NUM> and a second panel <NUM>. If the apparatus is an apparatus having a lateral opening, the first panel <NUM> may be a door frame or a cabinet body, and the second panel <NUM> is a door plate. If the apparatus is a container having a top opening, the first panel <NUM> may alternatively be a side frame of the container, and the second panel <NUM> is a lid. The foregoing is merely an example for description and is not used as a specific limitation. Certainly, the first panel <NUM> and the second panel <NUM> may alternatively be interchanged. The first panel <NUM> is a door plate or a lid, and the second panel <NUM> may be a door frame, a cabinet body, or a side frame. The first panel <NUM> and the second panel <NUM> used in this embodiment are merely for ease of description. It is emphasized that a part of the door lock assembly is installed on the first panel <NUM>, and another part of the door lock assembly <NUM> is installed on the second panel <NUM>. The first panel <NUM> and the second panel <NUM> are locked with and separated from each other by using the door lock assembly <NUM>. In another embodiment, the first panel <NUM> and the second panel <NUM> may alternatively be merely fixing points at which the door lock assembly <NUM> is fastened. In each of <FIG>, an example in which two door lock assemblies <NUM> are disposed on the apparatus is used. This is not a restrictive description of an implementation, and a specific quantity is set based on an actual case.

The door lock assembly <NUM> is described in detail below.

As shown in <FIG>, the door lock assembly <NUM> includes a clamping portion <NUM> fastened to the first panel <NUM> and a lock cylinder <NUM> fastened to the second panel <NUM>. As shown in <FIG> and <FIG>, the lock cylinder <NUM> includes a shaft body <NUM> and a guiding head <NUM> disposed at an end of the shaft body <NUM>, and a joint of the guiding head <NUM> and the shaft body <NUM> is provided with a first concave portion <NUM>. Preferably, in this embodiment, the guiding head <NUM> is one of a frustum, a pyramid, and a cone. In <FIG> and <FIG>, the pyramid is used as an example for description. A quantity of guiding bevels of the pyramid is preferentially set to an even number. An objective of symmetrically disposing an even quantity of guiding bevels is to lock the lock cylinder <NUM> with the clamping portion <NUM> by inserting the lock cylinder <NUM> into the clamping portion <NUM> through guiding of the guiding head <NUM> in a relatively easy manner.

As shown in <FIG> and <FIG>, the clamping portion <NUM> includes a base <NUM> and a clamp <NUM>. The base <NUM> is provided with a first through hole <NUM> for the shaft body <NUM> and the guiding head <NUM> to pass through. The clamp <NUM> is configured to clamp the first concave portion <NUM> on the lock cylinder <NUM>. The guiding head <NUM> and the shaft body <NUM> pass through the first through hole <NUM> on the base <NUM> of the clamping portion <NUM> to be locked with the clamp <NUM>, so that the first panel <NUM> is locked with the second panel <NUM>. The guiding head <NUM> and the shaft body <NUM> are detached from the clamp <NUM> with an external force, so that the first panel <NUM> is detached from the second panel <NUM>. In this embodiment, the clamp <NUM> further includes a first elastic arm <NUM> and a second elastic arm <NUM>. The first elastic arm <NUM> and the second elastic arm <NUM> are fastened to a same side surface of the base <NUM> in an arc manner. Preferably, the first elastic arm <NUM> and the second elastic arm <NUM> are symmetrically disposed. A gap having a preset width is formed between tail ends of the first elastic arm <NUM> and the second elastic arm <NUM>. To facilitate alignment between the lock cylinder <NUM> and the clamp <NUM> to enable the lock cylinder <NUM> to be successfully inserted into the clamp <NUM>, the gap between the first elastic arm <NUM> and the second elastic arm <NUM> and the first through hole <NUM> are located in a same plane.

As shown in <FIG> and <FIG>, the first concave portion <NUM> further includes a first inclined surface <NUM> and a second inclined surface <NUM>. The first inclined surface <NUM>, the second inclined surface <NUM>, and the guiding head <NUM> facilitate formation of the first concave portion <NUM>. Preferably, the first inclined surface <NUM> and the second inclined surface <NUM> are symmetrically disposed.

When the guiding head <NUM> of the lock cylinder <NUM> is inserted into the clamp <NUM>, the guiding head <NUM> enables the first elastic arm <NUM> and the second elastic arm <NUM> to elastically extend outward. When the guiding head <NUM> exceeds the gap, the first elastic arm <NUM> and the second elastic arm <NUM> restore elasticity and clamp the first concave portion, that is, clamp the first inclined surface <NUM> and the second inclined surface <NUM>. Mutual combination between the guiding head <NUM> and the open-type first elastic arm <NUM> and second elastic arm <NUM> forms a torque when a door is closed. Therefore, automatic locking between the first panel <NUM> and the second panel <NUM> can be implemented without turning a key. When the lock cylinder <NUM> is detached from the clamp <NUM>, when the lock cylinder <NUM> rotates by a specific angle, because parts, other than the first inclined surface <NUM> and the second inclined surface <NUM>, of the guiding head <NUM> and the shaft body <NUM> are not disposed in a concave manner, it is quite easy to smoothly detach the lock cylinder <NUM> from the first elastic arm <NUM> and second elastic arm <NUM> with a little external force during detaching.

As shown in <FIG>, <FIG>, and <FIG>, the second panel <NUM> is provided with a second concave portion <NUM> for accommodating the lock cylinder <NUM> and a second through hole <NUM> for the lock cylinder <NUM> to pass through. The second concave portion <NUM> is provided with a limiting groove <NUM> configured to limit a rotating angle of the lock cylinder <NUM>. The shaft body <NUM> of the lock cylinder <NUM> is provided with at least one limiting block <NUM> corresponding to the limiting groove <NUM>, and the limiting block <NUM> may be a protrusion. When the lock cylinder <NUM> rotates in the second concave portion <NUM>, the limiting block <NUM> rotates in the limiting groove <NUM>. The lock cylinder <NUM> and the second panel <NUM> limit an unlocking angle by using the limiting block <NUM> and the limiting groove <NUM>. The shaft body <NUM> of the lock cylinder <NUM> is further provided with a supporting surface <NUM> corresponding to the second concave portion <NUM>. Preferably, the supporting surface <NUM> is perpendicularly fastened to the shaft body <NUM>. It should be noted that, the supporting surface <NUM> and the shaft body <NUM> may be integrally formed or may be implemented in another manner.

Further, in another embodiment, the door lock assembly <NUM> further includes a clip spring <NUM> configured to fasten the lock cylinder <NUM> and the second panel <NUM>. A length or a diameter of the clip spring <NUM> is preferably greater than a diameter of the second through hole <NUM>. In this way, the lock cylinder <NUM> is not detached from the second panel <NUM> when the clip spring <NUM> is clipped to the lock cylinder <NUM>. The shaft body <NUM> of the lock cylinder <NUM> is provided with a third concave portion <NUM> corresponding to the clip spring <NUM>. When the lock cylinder <NUM> is placed in the second concave portion <NUM>, the lock cylinder <NUM> is fastened to the second panel <NUM> by clipping the clip spring <NUM> to the third concave portion <NUM>. An elastic characteristic of the clip spring <NUM> not only plays a role of fastening the lock cylinder <NUM> to the second panel <NUM>, but also keeps a function that the lock cylinder <NUM> can freely rotate in the second concave portion <NUM>.

As shown in <FIG> and <FIG>, an external surface of the supporting surface <NUM> is provided with an unlocking portion <NUM> having a preset shape, and the unlocking portion <NUM> is shown in figures by using a common triangle. Preferably, to beautify design, a sum of thicknesses of the supporting surface <NUM> and the unlocking portion <NUM> is not greater than a depth of the second concave portion, so that the top of the unlocking portion <NUM> is not higher than the second panel <NUM>. In this embodiment, a key with a groove in same preset shape may be used to turn the unlocking portion <NUM> to drive the lock cylinder to rotate, so that the first panel <NUM> is detached from the second panel <NUM>.

In the door lock assembly disclosed in the embodiments of the present invention, the lock cylinder <NUM> is locked with the clamping portion <NUM> by inserting the lock cylinder <NUM> into the clamping portion <NUM> through guiding of the guiding head <NUM>. During detaching, the guiding head <NUM> and the shaft body <NUM> can be detached from the clamp <NUM> with a little external force, so that the first panel <NUM> is detached from the second panel <NUM>. The door lock assembly has few parts, low costs, and strong practicality, and it is simple to assemble the door lock assembly.
