[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model achieves a stable connection between the lock cylinder and the lock shell by setting a first positioning block on the outside of the lock cylinder shell and setting a first slot for placing the first positioning block on the outer periphery of the mounting hole, and then using a first screw to fix the first positioning block on the first slot.

[0026] The implementation, functional features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0027] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:
[0028] Reference Figures 1-4 This utility model provides an embodiment of a spherical lock structure.
[0029] A spherical lock structure includes a lock housing 1 and a lock cylinder 2. The lock housing 1 has a mounting panel 11 with mounting holes 12. The lock cylinder 2 passes through the front end of the lock housing 1 and the mounting holes 12. The lock cylinder 2 includes a lock cylinder outer shell 3, within which a rotating shaft 4 is movably connected.
[0030] A connection structure is provided between the outer side of the lock cylinder housing 3 and the mounting panel 11. The connection structure is used to fix the lock cylinder housing 3 and the mounting panel 11 so that the lock cylinder can work stably.
[0031] The connection structure includes a first positioning block 31 disposed on the outside of the lock cylinder housing 3, a first locking position 13 disposed on the outer periphery of the mounting hole 12, and a first screw 14. The first positioning block 31 is placed on the first locking position 13 and fixed on the first locking position 13 by the first screw 14, thereby achieving a stable connection between the lock cylinder 2 and the lock housing 1, and making the installation and operation of the lock cylinder 2 convenient. Moreover, the connection structure is simple.
[0032] like Figure 3 As shown, the lock cylinder housing 3 is provided with a second positioning block 32 located in front of the first positioning block 31, a second locking position 15 is provided in front of the mounting panel 11, and a first locking position 13 is provided in the back of the mounting panel 11. After the first positioning block 31 passes through the mounting hole 12, the lock cylinder 2 can rotate around the axis to lock the first positioning block 31 into the first locking position 13, and at the same time, it can lock the second positioning block 32 into the second locking position 15, achieving double precise positioning. This allows the lock cylinder 2 to be securely installed with only one first screw 14, reducing the number of first screws 14 required for installing the lock cylinder 2 and further simplifying the connection structure of the lock cylinder 2.
[0033] The first locking position 13 is located behind the second locking position 15. The first positioning block 31 and the second positioning block 32 are opposite each other. In the prior art, an electric screwdriver is usually used to install the first screw 14 into the mounting hole 12. During the installation of the first screw 14, since the second positioning block 32 is located in front of the first positioning block 31, the second positioning block 32 can provide support for the first positioning block 31, reducing the impact on the lock cylinder 2 during the installation of the first screw 14 and avoiding damage to the lock cylinder 2.
[0034] like Figure 2 As shown, the mounting panel 11 has screw holes 16 around the first locking position 13, and the first screw 14 includes a nut 141 and a screw 142, as shown. Figure 1 As shown, the screw 142 is connected to the screw hole 16, and the nut 141 presses the first positioning block 31 tightly onto the first locking position 13. Compared to the first screw 14 directly passing through the first positioning block 31 for fixation, this utility model optimizes the position of the screw hole 16 to avoid the first screw 14 damaging the first positioning block 31, thus ensuring the integrity of the lock cylinder 2, and further reducing the impact on the lock cylinder 2 during the installation of the first screw 14 by the electric screwdriver.
[0035] like Figure 2 As shown, the shape of the mounting hole 12 is similar to the vertical cross-sectional shape of the lock cylinder housing 3 where the first positioning block 31 is located. The mounting hole 12 is slightly larger than the vertical cross-sectional shape of the lock cylinder housing 3 where the first positioning block 31 is located, so that the lock cylinder 2 can pass through smoothly.
[0036] A solid boss 17 is provided around the mounting hole 12 on the back of the mounting panel 11. The first locking position 13 and the screw hole 16 are both located on the solid boss 17.
[0037] The spherical lock structure also includes a fingerprint module 5 and a touch module 6 installed on the side wall of the lock housing 1. The touch module 6 includes a touch panel 61, and the fingerprint module 5 is located on the side wall of the lock housing 1. Users can unlock the lock using fingerprints, passwords, or keys, providing them with more unlocking options.
[0038] Both the front and rear ends of the lock housing 1 are open. There is a mounting groove 18 between the front opening of the lock housing 1 and the mounting panel 11. The touch module 6 is installed in the mounting groove 18, and the touch panel 61 is installed in the front opening of the lock housing 1. This makes full use of the internal space of the lock housing 1, which helps to reduce the overall volume of the ball lock and make it more compact.
[0039] The touch panel 61 has a through hole 62 for the lock cylinder 2 to pass through. A connecting post 63 is provided on the back of the touch panel 61, and the connecting post 63 is connected to the mounting panel 11. In this embodiment, the mounting panel 11 is fixedly connected to the connecting post 63 by a second screw 64.
[0040] like Figure 4 As shown, the lock cylinder housing 3 has an axially extending shaft channel 33, through which a rotating shaft 4 passes. A keyhole 46 is located at the front end of the rotating shaft 4. The outer side of the rotating shaft 4 has a protruding ring 41 located in front of the shaft channel 33 and an annular groove 42 located behind the shaft channel 33. The outer diameter of the protruding ring 41 is larger than the inner diameter of the shaft channel 33. An arc-shaped fixing member 43 is engaged with the annular groove 42. The outer diameter of the arc-shaped fixing member 43 is larger than the inner diameter of the shaft channel 33. The lock cylinder 2 also includes a translational shaft 7. The rotating shaft 4 has a groove 44 for placing the translational shaft 7. The translational shaft 7 and the rotating shaft 4 are connected by a transmission structure. When the key is inserted into the keyhole 46 and rotated, the key drives the rotating shaft 4 to rotate around the shaft. The rotating shaft 4, through the transmission structure, drives the translational shaft 7 to move in the front-back direction.
[0041] The transmission structure includes an arc-shaped hole 45 provided in the rotating shaft body 4 and a guide post 71 provided on the outside of the translation shaft body 7, with the guide post 71 passing through the arc-shaped hole 45.
[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
