[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0021] Reference Figure 1-4 As shown, an ecological lock handle modular structure includes a handle shell 1, a lock core module 2, and a cover plate 3. The handle shell 1 has a first mounting groove 4 and a second mounting groove 5, and the first mounting groove 4 is communicated with the second mounting groove 5. The handle shell 1 is provided with a through hole 6 at the bottom corresponding to the first mounting groove 4. The lock core module 2 is installed in the first mounting groove 4, and the cover plate 3 is installed in the second mounting groove 5 and covers the lock core module 2. The lock core module 2 is fixedly connected to the handle shell 1 on one side away from the cover plate 3, and the other side is snap-connected to the cover plate 3.
[0022] When assembling the modular structure of the ecological lock handle, first snap the lock core module 2 and the cover plate 3 together, then place the lock core module 2 in the first mounting groove 4. At this time, the cover plate 3 falls into the second mounting groove 5. The lock core module 2 is pressed tightly in the first mounting groove 4 by pressing the cover plate 3, and the lock core module 2 is fixedly connected by the locking piece. This arrangement can simplify the assembly process of the cover plate 3 and the lock core module 2 and improve the overall assembly efficiency. The through hole 6 at the bottom of the first mounting groove 4 of the handle housing 1 is used to connect the lock core module 2 with the external lock body components.
[0023] The lock core module 2 includes a lock core seat 7 and a lock core assembly 8. The lock core assembly 8 is arranged on the lock core seat 7. A plurality of claws 9 are provided on one side of the cover plate 3 that cooperates with the lock core seat 7. The lock core seat 7 is provided with a plurality of slots 10 that cooperate with the claws 9. The positions of the claws 9 and the slots 10 are correspondingly arranged.
[0024] The snap connection between the cover plate 3 and the lock cylinder seat 7 is realized by the claw 9 and the slot 10. The claw 9 and the cover plate 3 are integrally formed, and the slot 10 is opened at the position of the lock cylinder seat 7 corresponding to the claw 9, and the positions of the two are set correspondingly; when assembling the cover plate 3 and the lock cylinder seat 7, align the claw 9 on the cover plate 3 with the slot 10 on the lock cylinder seat 7 and apply a certain pressure, and the claw 9 can be elastically deformed and then embedded in the slot 10.
[0025] There are two claws 9 and two slots 10, and the two claws 9 are arranged diagonally along the axis of the handle rotation direction. The two claws 9 are distributed diagonally along the axis of the handle rotation direction on the side where the cover plate 3 and the lock cylinder seat 7 mate, and the corresponding two slots 10 are also distributed diagonally on the lock cylinder seat 7. When the cover plate 3 and the lock cylinder seat 7 are assembled, the two diagonally arranged claws 9 are respectively embedded in the corresponding slots 10. The two diagonally arranged claws 9 can reduce the difficulty of mold processing and the cost of material use, and the two claws 9 can also limit the relative rotation of the cover plate 3 and the lock cylinder seat 7 after installation.
[0026] In this embodiment, the cover plate 3 is provided with a release groove 11 on one side corresponding to the claw 9, which passes through the installation direction of the claw 9. When the cover plate 3 needs to be removed from the lock cylinder seat 7, a tool (such as a flat-blade screwdriver) can be inserted into the release groove 11. The tool applies a force to the claw 9 in the direction away from the slot 10 through the release groove 11, causing the claw 9 to be elastically deformed and then disengaged from the slot 10.
[0027] The cover plate 3 is provided with a plurality of support plates 12 on one side of the cover plate 3 that abut against the lock cylinder seat 7. The support plates 12 are integrally formed with the cover plate 3. The provision of the support plates 12 can reduce the deformation of the cover plate 3 when pressed by an external force, avoid the increase in the clearance between the claws 9 and the slots 10 due to deformation of the cover plate 3, and improve the tightness of the connection between the cover plate 3 and the lock cylinder seat 7.
[0028] In this embodiment, there are two support plates 12, which are arranged diagonally along the axis of the handle housing 1 in the rotation direction and cross the claws 9. This arrangement ensures the supporting effect without excessively increasing the weight and processing cost of the cover plate 3, thus taking into account both structural stability and economy.
[0029] The support plate 12 is curved to increase the contact area between the support plate 12 and the lock cylinder seat 7. The contact mode between the curved support plate 12 and the lock cylinder seat 7 changes from flat contact to curved surface contact, and the contact area is increased compared to the straight support plate 12. The larger contact area enables the support plate 12 to provide more stable support for the cover plate 3, dispersing the pressure on the cover plate 3. The support plate 12 bends and extends along the circumference of the lock cylinder seat 7. This circumferentially curved and extended structure further increases the contact area between the support plate 12 and the lock cylinder seat 7, and the contact area more closely conforms to the shape of the lock cylinder seat 7, allowing the supporting force to be more evenly transmitted to the cover plate 3, reducing local deformation of the cover plate 3 caused by uneven force.
[0030] In another embodiment, in order to fully improve the connection strength between the lock cylinder seat 7 and the cover plate 3, a plurality of the claws 9 and the support plates 12 are alternately distributed along the circumference of the lock cylinder seat 7. The cover plate 3 is provided with a locking member fixedly connected to the handle housing 1, which further improves the connection strength between the cover plate 3 and the handle housing 1.
[0031] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
