Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an intelligent lock that prevents the lock tongue strip from jamming and enables the horizontal and vertical installation of the lock body. Background Art

[0002] Generally, there are two unlocking methods for intelligent locks. One is that fingerprint, password, and face recognition drive the internal mechanism to rotate to achieve the purpose of unlocking. The other is the backup unlocking method, which is to insert a key and manually rotate to unlock. Sometimes, the two unlocking methods conflict. For example, Figures 1 - 2 As shown, there is a partition 11 in the middle of the swing rod gear 4. Sometimes, the front lock tongue strip 2 will top on the partition 11, resulting in ineffective rotation and inability to unlock normally. Therefore, there are strict restrictions on the length of the front lock tongue strip 2. There are two rib strips 12 on the inner side wall of the upper rotating shaft of the original swing gear 4. Normally, the front lock tongue strip 2 is inserted into the rotating shaft, and the force acts on the two rib strips 12 to twist the swing gear 4. However, during use, the front lock tongue strip 2 often twists or deforms, causing the front lock tongue strip 2 to top on the side wall rib strip 12 and unable to twist normally. In addition, as Figures 3 - 4 shown, the traditional lock body swing shaft 3 also has a structure of two rib strips 12, which requires that the lock body can only be installed in one installation method, and the installation and use scenarios are limited. Summary of the Utility Model

[0003] In view of the deficiencies in the prior art, the utility model provides an intelligent lock that prevents the lock tongue strip from jamming and enables the horizontal and vertical installation of the lock body.

[0004] An embodiment of the utility model provides an intelligent lock that prevents the lock tongue strip from jamming and enables the horizontal and vertical installation of the lock body, including a housing, a front lock tongue strip, a swing shaft, a swing rod gear, a swing rod fixing bracket, and a rear lock tongue strip. A first circular hole is provided in the middle of the swing shaft, and four first protrusions are provided on the inner side wall of the first circular hole near the opening side. The four first protrusions form a "cross" hole.

[0005] A second circular hole is provided in the middle of the swing rod gear, and two second protrusions are provided on the inner side wall of the second circular hole near the opening side. The two second protrusions are symmetrically arranged along a diameter line of the second circular hole.

[0006] Furthermore, the first protrusion is integrally formed with the swing shaft, and the two sides of the first protrusion are at right angles.

[0007] Furthermore, the second protrusion is integrally formed with the swing rod gear, and the two sides of the second protrusion are at right angles.

[0008] Further, the diameter of the circumscribed circle of the "plus" - shaped hole is greater than the width of the front locking tongue bar, and the width value at the narrowest part of the "plus" - shaped hole is greater than the thickness of the front locking tongue bar.

[0009] Further, the distance value between the two second protrusions is greater than the thickness of the front locking tongue bar, and the vertical distance between the extension lines of the two second protrusions is greater than the thickness of the front locking tongue bar.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In this application, by removing the middle partition of the swing rod gear, the locking tongue bar can drive the swing gear to rotate more smoothly without the situation of unable to rotate. At the same time, the length requirement for the locking tongue bar is more flexible, greatly improving the error - tolerance rate of unlocking. By designing the top of the swing shaft as a cross - hole structure, the lock body can be installed horizontally or vertically, and the usage scenarios are more extensive.

Detailed implementation mode

[0023] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0024] As Figures 1 - 10 shown, an intelligent lock for preventing the locking tongue bar from jamming and realizing the horizontal and vertical installation of the lock body includes a housing 1, a front locking tongue bar 2, a swing shaft 3, a swing rod gear 4, a swing rod fixing bracket 5 and a rear locking tongue bar 6. The front locking tongue bar 2 and the rear locking tongue bar 6 are collectively referred to as the locking tongue bar. A first circular hole 7 is provided in the middle of the swing shaft 3. Four first protrusions 8 are provided on the inner side wall of the first circular hole 7 close to the opening side. The four first protrusions 8 form a "cross" hole. The diameter of the circumscribed circle of the "cross" hole is greater than the width of the front locking tongue bar 2, and the width value of the narrowest part of the "cross" hole is greater than the thickness of the front locking tongue bar 2, so as to ensure that the front locking tongue bar 2 can smoothly pass through the "cross" hole and be inserted into the first circular hole 7. At the same time, by rotating the front locking tongue bar 2, its two sides can be respectively abutted against the side walls of two of the first protrusions 8, and then the swing rod gear 4 can be driven to rotate by the front locking tongue bar 2. Compared with the traditional method of setting two ribs 12 as shown in Figure 3 and Figure 4 , in this application, by setting four first protrusions 8 to form a cross-hole structure, the lock body can be installed horizontally or vertically, and the use scenarios are more extensive.

[0025] A second circular hole 9 is provided in the middle of the swing rod gear 4. Two second protrusions 10 are provided on the inner side wall of the second circular hole 9 close to the opening side. The two second protrusions 10 are symmetrically arranged along a diameter line of the second circular hole 9. The distance between the two second protrusions 10 is greater than the thickness of the front locking tongue bar 2, and the vertical distance between the extension lines of the two second protrusions 10 is greater than the thickness of the front locking tongue bar 2, so as to ensure that the front locking tongue bar 2 can smoothly insert into the first circular hole 7 through the gap between the two second protrusions 10. At the same time, by rotating the front locking tongue bar 2, its two sides can be respectively abutted against the side walls of the two second protrusions 10, and then the swing rod gear 4 can be driven to rotate by the front locking tongue bar 2. Compared with the traditional setting methods shown in Figure 1 and Figure 2 , in this application, the partition plate 11 is removed, the second circular hole 9 is designed as a through hole, the length requirement for the locking tongue bar is more flexible, and two second protrusions 10 are used instead of two ribs 12. This not only saves metal materials, but also there is no rib 12 blocking in the second circular hole 9, and the insertion and rotation angle of the front locking tongue bar 2 can be made wider. It will not cause the situation of jamming with the rib 12 due to the distortion or deformation of the front locking tongue bar 2 after long-term use.

[0026] Specifically, the first protrusion 8 is integrally formed with the swing shaft 3, and two sides of the first protrusion 8 are arranged at a right angle; the second protrusion 10 is integrally formed with the swing rod gear 4, and two sides of the second protrusion 10 are arranged at a right angle. The right-angle design of the first protrusion 8 and the second protrusion 10 can increase the contact area with the front lock tongue bar 2 and enhance the transmission effect of the torsional force during the unlocking and locking processes.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
