Description
Technical Field
[0001] The utility model relates to a spherical lock, in particular to a multifunctional spherical lock. Background Art
[0002] A spherical lock mainly consists of a lock head, a lock body, a lock tongue, a handle, etc. The lock head contains structures such as pins or blades. The lock body is the main part installed inside the door. The lock tongue is used to insert into the door frame to achieve locking. The handle is a spherical knob used to operate the opening and closing of the lock.
[0003] Currently, the handle housing material of spherical locks generally uses materials such as zinc alloy or aluminum. When performing surface treatment, most of them use powder spraying or electroplating methods. However, the surface display effects of these two methods are poor or the colors are single. The surface oxidation treatment process can show various complex and bright colors compared with the above two surface treatment processes. However, when using a simple die-casting machine to manufacture the handle housing, pores will appear on the surface during the oxidation treatment process, and it is impossible to achieve a handle that is both smooth and has a combination of diverse colors. Summary of the Utility Model
[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a multifunctional spherical lock.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: It further includes a lock core, a rotating square rod, a rotating core rod, and a fixing steel sheet. The handle includes an inner shell and an outer shell. The outer shell is manufactured by a drawing aluminum process. The inner shell is provided with a blocking part and abuts against one side of the outer shell. A fixing piece is arranged on the other side of the outer shell to form the fixation of the outer shell and the inner shell. A keyhole is arranged at one end of the outer shell. The lock core is arranged inside the outer shell and is opposite to the keyhole. The other side of the lock core opposite to the keyhole is linked with the rotating core rod. The fixing steel sheet is arranged at the other end of the outer shell relative to the end where the keyhole is located. A square groove adapted to the shape of the rotating square rod is arranged inside the fixing steel sheet to form the synchronous rotation of the outer shell and the rotating square rod.
[0006] By adopting the above technical solutions, when the key is inserted, it drives the lock core to rotate, and the rotating core rod rotates accordingly. Then it cooperates with the lock body. At this time, the rotating square rod is linked with the lock tongue of the lock body. Then hold the handle and rotate it, driving the rotating square rod to rotate, making the lock tongue contract inward to complete the opening action. The outer shell is manufactured by a drawing aluminum process, making the outer surface of the outer shell have high tightness and few pores. It can be surface-treated by oxidation, with better surface treatment and the ability to use more colors. Moreover, the inner surface of the outer shell manufactured by the drawing aluminum process is smooth. Therefore, the blocking part and the fixing piece of the inner shell are used to form the fixation of the outer shell.
[0007] The present utility model is further configured as follows: It includes a handle, a shielding cover, a rotating column, and a fixing mechanism. The handle has a housing, and one end of the housing is provided with a keyhole. The rotating column is rotatably arranged at the end of the housing and is at the same end as the keyhole. The shielding cover is arranged on the rotating column. The shielding cover has a shielding state in which the keyhole is shielded and a use state in which the keyhole is exposed. The fixing mechanism is arranged inside the housing and has a fixing state in which the shielding cover is maintained in the shielding state.
[0008] By adopting the above technical solution, when not in use, rotate the shielding cover so that the shielding cover rotates to cover the keyhole, and fix the shielding cover through the fixing mechanism, thereby playing a role in shielding the keyhole and preventing impurities from entering the keyhole, which may affect the subsequent insertion and rotation of the key.
[0009] The present utility model is further configured as follows: The fixing mechanism includes a return spring, a pushing block, and a sliding block. The return spring is arranged on the outer periphery of the rotating column and has a pulling state in which it pulls the shielding cover to move towards the direction of the housing. A pushing groove is provided at the end of the housing, and the pushing block is slidably arranged in the pushing groove. The pushing block has a pushing portion extending outside the pushing groove, and the top of the pushing block has a pushing inclined surface. The sliding block is arranged at the bottom of the shielding cover, and the sliding block has a sliding inclined surface adapted to the pushing inclined surface. When the sliding inclined surface abuts against the pushing inclined surface, the sliding block enters the pushing groove, and the shielding cover is in the shielding state.
[0010] By adopting the above technical solution, when the key needs to be used, push the pushing portion of the pushing block inward so that the pushing inclined surface moves inward, thereby causing the sliding block to move upward, so that the sliding block moves out of the pushing groove. At this time, the user can rotate the shielding cover to turn the shielding cover away from the keyhole and expose the keyhole. When the key is not needed, rotate the shielding cover until the sliding block on the shielding cover rotates to face the pushing groove. Under the pulling of the return spring, the sliding block moves downward so that the sliding inclined surface abuts against the pushing inclined surface, and at this time, the shielding block cannot be rotated any further.
[0011] The present utility model is further configured as follows: An outer peripheral track adapted to the movement track of the sliding block is provided on the housing, and the depth of the outer peripheral track gradually decreases from the direction away from the pushing groove.
[0012] By adopting the above technical solution, the setting of the outer peripheral track enables the sliding block to gradually push the shielding cover upward or downward when the shielding cover is rotated out and rotated in.
[0013] The present utility model is further configured as follows: The outer surface of the housing has an oxide layer.
[0014] By adopting the above technical solution, an oxidation treatment is performed on the outer surface of the housing.
[0015] The present utility model is further configured as follows: A plurality of friction blocks are arranged on the outer periphery of the housing.
[0016] By adopting the above technical solution, the setting of the friction block prevents the phenomenon of slipping when holding the handle.
[0017] The present utility model is further configured as: an ambient light is provided on the outer periphery of the housing.
[0018] The present utility model is further configured as: a display screen is provided on the shielding cover.
[0019] The present utility model is further configured as: a sensor module and a Bluetooth module are provided inside the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As Figures 1-4 shown, the present utility model discloses a multifunctional spherical lock, including a handle 1, characterized in that: it further includes a lock core 5, a rotating square rod 51, a rotating core rod 52 and a fixing steel sheet 53. The handle 1 includes an inner shell 6 and an outer shell 11. The outer shell 11 is manufactured by the drawn aluminum process. The inner shell 6 is provided with a blocking portion 61 and abuts against one side of the outer shell 11. A fixing piece 7 is provided on the other side of the outer shell 11 to form the fixation of the outer shell 11 and the inner shell 6. A keyhole 12 is provided at one end of the outer shell 11. The lock core 5 is arranged inside the outer shell 11 and is opposite to the keyhole 12. The other side of the lock core 5 relative to the keyhole 12 is linked with the rotating core rod 52. The fixing steel sheet 53 is arranged at the other end of the outer shell 11 relative to the end where the keyhole 12 is located. A square groove 54 adapted to the shape of the rotating square rod 51 is provided inside the fixing steel sheet 53 to form the synchronous rotation of the outer shell 11 and the rotating square rod 51. When the key is inserted, it drives the lock core 5 to rotate, and the rotating core rod 52 rotates accordingly. Then it cooperates with the lock body. At this time, the rotating square rod 51 is linked with the lock tongue of the lock body. Then hold the handle 1 and rotate it, driving the rotating square rod 51 to rotate, so that the lock tongue contracts inward to complete the opening action. The outer shell 11 is manufactured by the drawn aluminum process, so that the outer surface of the outer shell has high tightness and few air holes. It can be surface-treated by oxidation, with better surface treatment, and more colors can be used. And the inner part of the outer shell 11 made by the drawn aluminum process is smooth. Therefore, the blocking portion 61 of the inner shell 6 and the fixing piece 7 are used to form the fixation of the outer shell 11.
[0028] It includes a handle 1, a shielding cover 2, a rotating column 3 and a fixing mechanism 4. The handle 1 has an outer shell 11. A keyhole 12 is provided at one end of the outer shell 11. The rotating column 3 is rotatably arranged at the end of the outer shell 11 and is at the same end as the keyhole 12. The shielding cover 2 is arranged on the rotating column 3. The shielding cover 2 has a shielding state of covering the keyhole 12 and a use state of exposing the keyhole 12. The fixing mechanism 4 is arranged inside the outer shell 11 and has a fixed state of maintaining the shielding state of the shielding cover 2. When not in use, rotate the shielding cover 2 so that the shielding cover 2 rotates to cover the keyhole 12, and fix the shielding cover 2 through the fixing mechanism 4, thereby playing a role in shielding the keyhole 12 and preventing impurities from entering the keyhole 12 and affecting the subsequent insertion and rotation of the key.
[0029] The fixing mechanism 4 includes a return spring 43, a pushing block 41 and a sliding block 42. The return spring 43 is arranged on the outer periphery of the rotating column 3 and has a pulling state that pulls the shielding cover 2 towards the direction of the housing 11. A pushing groove 44 is provided at the end of the housing 11, and the pushing block 41 is slidably arranged in the pushing groove 44. The pushing block 41 has a pushing portion 45 extending outside the pushing groove 44. The top of the pushing block 41 has a pushing inclined surface 46. The sliding block 42 is arranged at the bottom of the shielding cover 2, and the sliding block 42 has a sliding inclined surface 47 adapted to the pushing inclined surface 46. When the sliding inclined surface 47 abuts against the pushing inclined surface 46, the sliding block 42 enters the pushing groove 44, and the shielding cover 2 is in a shielding state. When the key is needed, the pushing portion 45 of the pushing block 41 is pushed inward, so that the pushing inclined surface 46 moves inward, thereby causing the sliding block 42 to move upward, so that the sliding block 42 moves out of the pushing groove 44. At this time, the user can rotate the shielding cover 2 to turn the shielding cover 2 away from the keyhole 12, exposing the keyhole 12. When the key is not needed, the shielding cover 2 is rotated until the sliding block 42 on the shielding cover 2 rotates to be opposite to the pushing groove 44. Under the pulling of the return spring 43, the sliding block 42 moves downward, so that the sliding inclined surface 47 abuts against the pushing inclined surface 46. At this time, the shielding block cannot be rotated any more.
[0030] An outer peripheral track 48 adapted to the moving track of the sliding block 42 is provided on the housing 11, and the depth of the outer peripheral track 48 gradually decreases from the direction away from the pushing groove 44. The setting of the outer peripheral track 48 enables the sliding block 42 to gradually push the shielding cover 2 upward or downward when the shielding cover 2 is rotated out and rotated in.
[0031] The outer surface of the housing 11 has an oxide layer, and an oxidation treatment is performed on the outer surface of the housing 11.
[0032] A plurality of friction blocks 13 are arranged on the outer periphery of the housing 11. The setting of the friction blocks 13 prevents slipping when the handle 1 is held.
[0033] An atmosphere lamp 14 is arranged on the outer periphery of the housing 11, and a sensor module and a Bluetooth module are arranged inside the housing 11.
[0034] Working process: During installation, the lock body is installed inside the door, and the two door handles 1 are respectively installed on both sides of the door. When the key is needed, the pushing part 45 of the pushing block 41 is pushed inwards, causing the pushing inclined surface 46 to move inwards, thereby causing the sliding block 42 to move upwards, so that the sliding block 42 moves out of the pushing groove 44. At this time, the user can rotate the shielding cover 2 to turn the shielding cover 2 away from the keyhole 12, exposing the keyhole 12. After the key is inserted, it drives the lock core 5 to rotate, and the rotating core rod 52 rotates accordingly. Then it cooperates with the lock body. At this time, the rotating square rod 51 is linked with the lock tongue of the lock body. Then hold the door handle 1 and rotate it, driving the rotating square rod 51 to rotate, causing the lock tongue to contract inwards to complete the opening action. When the key is not needed, rotate the shielding cover 2 until the sliding block 42 on the shielding cover 2 rotates to face the pushing groove 44. Under the pulling of the return spring 43, the sliding block 42 moves downwards, causing the sliding inclined surface 47 to abut against the pushing inclined surface 46. At this time, the shielding block cannot rotate anymore.
