Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a lock core assembly. Background Art

[0002] The lock core assembly of an existing conventional lock generally includes a lock shell, an outer lock core and an inner lock core placed at both ends of the lock shell, and a toggle member located between the outer lock core and the inner lock core for toggling the bolt plate. The current toggle member is a rotary toggle that needs to rotate 360 ​​degrees, so a huge gap that can accommodate and avoid the rotary toggle must be provided at the corresponding position on the lock shell. It is precisely because of the existence of this huge gap that the connection between the inner and outer lock cores of the lock shell can only be located at the edge of the lock shell, and its cross-sectional area is also very small, becoming the most concentrated and weakest part of the entire lock core assembly (for the convenience of description, hereinafter referred to as the lock shell waist). Not only that, a large threaded hole must be provided at this lock shell waist with a very small cross-sectional area, resulting in a small cross-sectional area of ​​the lock shell waist, which is extremely weak and can be easily broken, increasing safety risks. Summary of the invention

[0003] In order to solve at least one of the problems mentioned in the above background technology, the present invention provides a lock core assembly, which can greatly increase the cross-sectional area of ​​the waist of the lock shell, enhance the strength of the lock shell, and make the lock shell not easily broken, thereby ensuring safety.

[0004] The specific technical solutions provided by the present invention are as follows:

[0005] In a first aspect, a lock core assembly is provided, comprising a lock housing and a lock core, wherein the lock housing is provided with a threaded hole, the lock core is rotatably arranged on the lock housing, and further comprising a toggle member coaxially arranged with the lock core, the toggle member being arranged on the lock housing and driven to rotate by the lock core, the toggle member comprising a paddle wheel and a paddle movably arranged on the paddle wheel, when the toggle member is rotated, the paddle can extend out of the paddle wheel to paddle a lock tongue plate, and after the lock tongue plate is paddled, as the toggle member rotates, the paddle can be partially or completely retracted into the part of the paddle wheel facing the threaded hole, and when the paddle can be partially retracted into the paddle wheel, an avoidance groove is provided on the lock housing above the threaded hole, and the part of the paddle extending out of the paddle wheel rotates into the avoidance groove.

[0006] By means of the above technical scheme, the lock core assembly of the present invention is provided with a paddle movably on the dial wheel.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] See also Figure 1 As described in the background technology, the current toggle is a rotary toggle that needs to rotate 360 ​​degrees. Therefore, a huge gap 101 that can accommodate and avoid the rotary toggle must be provided at the corresponding position on the lock housing 1 (the position corresponding to the threaded hole 11). It is precisely because of the existence of this huge gap 101 that the waist 16 of the lock housing can only be located at the edge of the lock housing 1, and its cross-sectional area is also very small, becoming the most concentrated and weakest part of the entire lock core assembly. Not only that, a large threaded hole 11 must be provided on the waist 16 of the lock housing with a very small cross-sectional area, resulting in a small cross-sectional area of ​​the waist 16 of the lock housing, which is extremely weak and can be easily broken, increasing safety risks.

[0043] When the lock is unlocked, the first locking member 721 is unlocked and the second locking member 721 is unlocked, and the key 100 is inserted into the first lock core 21, and the first transmission block 711 is pressed against the first transmission block 711, and the first projection 712 of the first transmission block 711 is inserted into the limiting groove 413; at the same time, the connecting hole of the first transmission block 711 is connected with the transmission rod 722, and the first transmission block 711 drives the transmission rod 722 and the second transmission block 721 to move inwardly, so that the connecting groove 723 of the second transmission block 721 leaves the connecting block 51, thereby releasing the transmission connection between the thumb wheel 41 and the second lock core 22. The first lock cylinder 21 rotates to drive the dial wheel 41 to rotate through the first transmission block 711, and the dial wheel 41 drives the paddle 42 to rotate. When the paddle 42 rotates, the pin shaft 421 on it moves along the first arc groove 31 or the second arc groove 32, so that the guiding effect of the first arc groove 31 or the second arc groove 32 can make the paddle 42 move radially along the dial wheel 41 when rotating. When the pin shaft 421 moves along the first arc groove 31, the toggle portion 422 extends out as a whole. The dial wheel 41 is used to unlock or lock the lock by toggling the bolt plate. At this time, the length of the toggle portion 422 extending out of the dial wheel 41 is relatively long. When the pin shaft 421 moves along the second arc groove 32, the toggle portion 422 partially extends out of the dial wheel 41. At this time, the length of the toggle portion 422 extending out of the dial wheel 41 is relatively short, that is, the toggle portion 422 can be extended and retracted on the dial wheel 41. After unlocking or locking, the toggle portion 422 is rotated and stored in the avoidance groove 12 on the lock housing 1, and the key 100 can be pulled out.

[0044] The process of unlocking or locking from the inside is as follows: the key 100 is inserted into the second lock cylinder 22, and the second transmission block 721 is pushed against and drives the second transmission block 721 to move outward on the second lock cylinder 22, and the connecting groove 723 of the second transmission block 721 is plugged into the connecting block 51; at the same time, the transmission rod 722 moves outward and connects with the connecting hole of the first transmission block 711, and the transmission rod 722 drives the first transmission block 711 to move outward so that the first boss 712 leaves the limiting groove 413 of the dial wheel 41, thereby The transmission connection between the dial wheel 41 and the first lock core 21 is released, and then the second lock core 22 rotates through the second transmission block 721 to drive the connecting block 51 and the connecting rod 5 to rotate, and the connecting rod 5 drives the dial wheel 41 to rotate through the incision 6, and the dial wheel 41 drives the paddle 42 to rotate. The working process of the rotation of the paddle 42 is the same as that when unlocking from the outside, that is, the toggle part 422 can be retracted on the dial wheel 41. After unlocking or locking, the toggle part 422 is rotated and stored in the avoidance groove 12 on the lock shell 1, and the key 100 can be pulled out.

[0045] When unlocking or locking, the lock core assembly of this embodiment can extend and retract the toggle portion 422 on the dial wheel 41, extending to toggle the lock tongue plate, and retracting to be stored in the avoidance groove 12. Since the length of the toggle portion 422 when retracted is shorter, the width (up and down direction) of the avoidance groove 12 can be set shorter. Compared with the huge notch set on the lock shell 1 in the prior art to accommodate and avoid the rotary plectrum, the width of the avoidance groove 12 on the lock shell 1 in the present invention is greatly reduced, and the distance between the threaded hole 11 of the lock shell 1 and the avoidance groove 12 is greater than the distance between the threaded hole and the notch in the prior art. The cross-sectional area of ​​the lock shell waist 16 is greatly increased, thereby enhancing the strength of the lock shell 1, and the lock shell 1 is not easily broken, thereby ensuring safety.

[0046] In another embodiment, a receiving groove 416 penetrating the outer wall of the dial wheel 41 is provided on the dial wheel 41, and the dial wheel 41 and the paddle 42 are synchronously driven by the lock cylinder 2 to rotate around the central axis of the lock cylinder 2. At the same time, when the dial wheel 41 rotates, the paddle 42 can also rotate relative to the dial wheel 41 in the receiving groove 416. One end of the paddle 42 is rotatably set on the side wall of the storage groove 416 away from the center of the dial wheel 41, for example, it can be rotatably set by a rotating shaft (not shown), and the paddle 42 can extend out of the storage groove 416 when it rotates, and can be partially or completely retracted into the storage groove 416 when the paddle 42 rotates.

[0047] In this embodiment, the paddle 42 is rotatably arranged at one end of the receiving groove 416 and an elastic member (not shown) is provided between the receiving groove 416, such as a torsion spring inserted on the rotating shaft, one end of the torsion spring is fixed to the rotating shaft, and the other end is fixed to the receiving groove 416. The lock cylinder 2 drives the dial wheel 41 to rotate, and the dial wheel 41 rotates to drive the paddle 42 to rotate together. When the receiving groove 416 is facing upward, most of the paddle 42 extends out of the receiving groove 416 to move the lock tongue plate to unlock or lock. When the receiving groove 416 is rotated to face downward, the paddle 42 extends out. Part of the dial 41 contacts the part of the lock housing 1 between the threaded hole 11 and the dial 41, and the paddle 42 is squeezed by the lock housing 1. The paddle 42 rotates around one end while being squeezed and gradually retracts into the receiving groove 416. The paddle 41 can be partially or completely retracted into the receiving groove 416. At this time, the elastic member is deformed to store elastic potential energy. As the dial 41 rotates, the receiving groove 416 rotates upward, the paddle 42 leaves the lock housing 1, the elastic member releases the elastic potential energy, and the paddle 42 extends most of the way out of the receiving groove 416 again to move the lock tongue plate.

[0048] When the paddle 42 can be partially retracted into the dial wheel 41, an avoidance groove 12 is provided on the lock housing 1 above the threaded hole 11 (between the threaded hole 11 and the dial wheel 41), and the paddle 42 is gradually retracted into the receiving groove 416 by the extrusion of the avoidance groove 12 and the rotation of the paddle 42 around one end thereof, and at the same time, the part of the paddle 42 extending out of the dial wheel 41 rotates into the avoidance groove 12, so that the width of the avoidance groove 12 can be set shorter. Compared with the huge notch 101 provided on the lock housing 1 in the prior art for accommodating and avoiding the rotary plectrum, the width of the avoidance groove 12 on the lock housing 1 in the present invention is greatly reduced, and the distance between the threaded hole 11 of the lock housing 1 and the avoidance groove 12 is greater than the distance between the threaded hole 11 and the notch 101 in the prior art, and the cross-sectional area of ​​the waist 16 of the lock housing is greatly increased, thereby enhancing the strength of the lock housing 1, and the lock housing 1 is not easily broken, thereby ensuring safety;

[0049] When the paddle 42 can be retracted as a whole into the part of the dial wheel 41 facing the threaded hole 11, the paddle 42 is gradually retracted as a whole into the receiving groove 416 due to the squeezing of the lock shell 1 below the dial wheel 41 and the rotation of the paddle 42 around one end thereof. Therefore, the position on the lock shell 1 corresponding to the paddle 42 does not need to be provided with an avoidance groove 12, thereby eliminating the notch on the lock shell 1 above the threaded hole 11, further increasing the cross-sectional area of ​​the lock shell waist 16, greatly enhancing the strength of the lock shell 1, and making the lock shell 1 not easily broken, thereby further ensuring safety.
