Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a rotary ecological lock. Background Art

[0002] Based on the prior art, i.e. the patented product with patent number: CN220849176U, the general scheme is as follows: when locking the door, it is only necessary to rotate the anti-lock knob, and the anti-lock knob drives the anti-lock cam to rotate through the linkage plate, and the anti-lock cam will squeeze the anti-lock ball outward, so that a part of the anti-lock ball passes through the ball hole and is placed in the locking groove, so that the outer handle connected to the outer handle head cannot rotate relative to the outer base, thereby realizing the anti-locking of the door lock; when unlocking, it is only necessary to rotate the anti-lock knob in the opposite direction, and the anti-lock knob drives the linkage plate to rotate in the opposite direction, so that the anti-lock cam can be turned to unlock the door. The ball avoids the cam surface of the anti-lock cam, so that the anti-lock ball is separated from the locking groove and retracted into the outside handle head, and the door lock can be unlocked; it can be seen that although it can also complete the locking and unlocking of the lock, it requires the linkage of the anti-lock ball and the anti-lock cam to promote the cooperation of the anti-lock ball and the locking groove. However, after the anti-lock ball, the anti-lock cam and the locking groove are locked, when they are violently rotated, there is spherical contact between the ball and the groove, and between the ball and the cam, which will still cause separation between the three, and thus its locking ability needs to be improved.

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model 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 should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-7 The utility model provides an embodiment: a rotary ecological lock, comprising an inner base 1; the inner base 1 comprises a lock shell 10 and a fixing member 16 fixed on a door body; a knob 11 is provided on one side of the lock shell 10, and a top column 13 is provided inside the lock shell 10; by rotating the knob 11, one end of the top column 13 is inserted into a pin hole 18 provided on the fixing member 16 to prevent the lock shell 10 from continuing to rotate.

[0023] In summary, after the knob 11 is used to push the top column 13 into the pin hole 18, the pin hole 18 uses a latch locking structure to replace the spherical locking structure of the prior art on the top column 13, so as to improve the braking ability of the lock. Even when the lock is violently unlocked, the top column 13 will be deformed, but it will still be inserted into the pin hole 18, so the lock housing 10 can be effectively prevented from rotating, so as to improve the ability of the lock to resist violent unlocking.

[0024] At the same time, by utilizing the linkage between the knob 11 and the top column 13, and then by utilizing the connection or separation between the top column 13 and the pin hole 18, the locking action or unlocking action of the lock can be completed. Compared with the prior art, the parts that structurally realize the locking action and the unlocking action are easy to process. In terms of locking ability, after the top column 13 is inserted into the pin hole 18, the anti-violence ability and locking ability of the lock are made stronger.

[0025] In order to improve the reliability of the contact and separation between the top column 13 and the pin hole 18, a protrusion 112 is provided on the side of the knob 11 facing the top column 13, and the protrusion 112 is in contact with the end of the top column 13 away from the pin hole 18, so that the top column 13 slides on the protrusion 112. Therefore, when the top column 13 slides on the protrusion 112, the top column 13 can be driven to slide in the installation cavity 111 to prevent the top column 13 from being smoothly inserted into the pin hole 18 or separated from the pin hole 18. Specifically, the protrusion 112 is high at one end and low at the other end. At this time, the top column 13 slides from high to low on the protrusion 112, so that the top column 13 is separated from the pin hole 18. On the contrary, the top column 13 slides from low to high on the protrusion 112, so that the top column 13 is inserted into the pin hole 18.

[0026] Furthermore, an elastic member 14 is also mounted on the outside of the top column 13, and the elastic member 14 is used to urge the top column 13 to always fit the protrusion 112, wherein the elastic member 14 is preferably a coil spring. Therefore, the top column 13 can reliably slide along the protrusion 112, so that the top column 13 can be smoothly connected or separated from the pin hole 18, and the locking and unlocking actions of the lock can be smoothly and reliably performed.

[0027] On the basis of the above scheme, since a slide groove 110 is further provided on the side of the lock housing 10 facing the knob 11, and a limit block 19 is further provided in the slide groove 110, and the continuous rotation of the knob 11 is prevented by the limit block 19, therefore, when the end face of the protrusion 112 abuts against the limit block 19, the continuous rotation of the knob 11 in the slide groove 110 can be prevented, which causes the top column 13 to be popped out and stuck on the limit block 19, thereby affecting the normal operation of the lock, so as to ensure the continuous and reliable locking and unlocking actions of the lock.

[0028] Furthermore, since a cover plate 12 is provided on the lock housing 10 and is connected to the lock housing 10 via the cover plate 12 so as to limit the sliding of the knob 11 within the slide groove 110, the position of the knob 11 is limited by the cover plate 12 to ensure that the knob 11 rotates stably and reliably, thereby ensuring smooth separation or contact between the top column 13 and the pin hole 18.

[0029] In addition, since a reset member 15 is provided between the fixing member 16 and the facing surface of the lock housing 10, and the reset member 15 is used to promote the reset of the lock housing 10 after rotation, when the unlocking action or the locking action is completed, after the force applied to the outside of the lock housing 10 disappears, the lock housing 10 can be smoothly reset, so that the lock can smoothly complete the locking action and the unlocking action, and ensure the continuous performance of the unlocking action and the locking action.

[0030] Specifically, since the fixing member 16 is also provided with a boss 17, and the pin hole 18 is opened on the boss 17, firstly, the boss 17 can be used to expand the depth of the pin hole 18, thereby improving the contact surface between the top column 13 and the pin hole 18; secondly, the boss 17 is used to enhance the bearing capacity of the pin hole 18 to avoid the top column 13 and the pin hole 18 from slipping off each other; thirdly, when the reset member 15 is a torsion spring, when the lock housing 10 rotates, the boss 17 prompts the torsion spring to rotate, and when the external force of the lock housing 10 disappears, the torsion spring is reset, driving the lock housing 10 to reset.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
