Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locks, in particular to a lock body. Background Art
[0002] After the door lock is installed on the door panel, the door can only be opened in one direction after installation because the latch bolt on the door lock has a direction. If you want to change the door opening direction, you need to turn the latch bolt of the door lock 180 degrees. At present, door locks need to be designed with latch bolts in different directions for different door opening directions. During installation, you need to carefully check the direction of the latch bolt. Otherwise, if the direction of the latch bolt is wrong, the door will not be able to close automatically. You need to disassemble the door lock and replace it with a latch bolt corresponding to the door opening direction. This can easily lead to errors in the production, sales and installation of the door lock, affecting the normal installation and use of the door lock. Utility Model Content

DETAILED DESCRIPTION
[0026] 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.
[0027] See also Figure 1-9The utility model provides an embodiment: a lock body, including a lock shell 1; a slanted tongue 6 is provided on the lock shell 1, and the slanted tongue 6 is connected to a reversing member 3 provided inside the lock shell 1 through a linkage rod 7; the reversing member 3 includes a shell 30, a sliding member 36 sliding inside the shell 30, and a pressing member 31 for causing the sliding member 36 to slide inside the shell 30; one end of the sliding member 36 slides in a slide groove 38 provided inside the shell 30, and the other end of the sliding member 36 extends out of the slide groove 38 and then contacts a baffle 8 provided at the lower end of the linkage rod 7; a driving member 37 is also provided inside the lock shell 1, and after the sliding member 36 is caused to separate from the baffle 8 by the driving member 37, the linkage rod 7 can automatically move upward.
[0028] In summary, when the pressing member 31 is pressed, the sliding member 36 can be caused to slide toward the inside of the housing 30 so that one end of the sliding member 36 is separated from the baffle 8. At this time, the driving member 37 can cause the linkage rod 7 to extend to the outside of the lock housing 1 until the inclined tongue 6 is completely separated from the lock housing 1. The inclined tongue 6 can then be rotated to achieve the reversal of the inclined tongue 6.
[0029] Based on this, through the above scheme, the device can realize convenient and rapid reversal of the oblique tongue 6, and can make the door lock suitable for doors with different door opening directions, so that the door lock does not need to be separately assembled according to different door opening directions in the production and manufacturing process, thereby avoiding the problem of low door lock installation efficiency caused by the mismatch between the door opening direction and the direction of the oblique tongue 6 of the door lock during the installation of the door lock; at the same time, it also avoids the problem of mixing and error caused by different directions of the oblique tongue 6 in the door lock production and sales units. In particular, the device has many advantages such as simple structure and easy operation while realizing the reversal of the lock tongue. Among them, the driving member 37 is preferably a torsion spring, one end of which is in conflict with the lock shell 1, and the other end is installed in a groove set in the middle of the shell 30.
[0030] Furthermore, since the pressing member 31 is slidably matched with the second guide surface 32 provided on the sliding member 36 through the first guide surface 33, the mutual cooperation of the two guide surfaces enables the pressing member 31 to stably and reliably push the sliding member 36 to slide.
[0031] At the same time, since the sliding member 36 slides in the slide groove 38 through the provided sliding portion 34, and the end of the sliding portion 34 away from the baffle 8 abuts against the slide groove 38 through the provided elastic member 35. Therefore, the sliding portion 34 slides inside the slide groove 38, so when the sliding member 36 slides outward to the maximum position, the slide groove 38 prevents it from continuing to slide, thereby preventing the sliding member 36 from being too tightly pressed against the linkage rod 7, causing the linkage rod 7 to have too much resistance when moving; and the setting of the slide groove 38 can guide the sliding member 36 to slide in a directional manner, so as to improve the reliability of the direction reversal of the inclined tongue 6. In addition, when the external force of the pressing member 31 disappears, the elastic member 35 can be used to cause the sliding member 36 to reset, so that one end of the sliding member 36 can be stuck on the baffle 8 to prevent the linkage rod 7 from moving outward; wherein, the elastic member 35 is preferably a coil spring.
[0032] Specifically, since the first guide surface 33 and the second guide surface 32 are inclined surfaces, there is a sufficient contact surface between the pressing member 31 and the sliding member 36 to ensure that the sliding member 36 slides in the shell 30 after the pressing member 31 is subjected to force. At the same time, the two guide surfaces are set as inclined surfaces, which allows the pressing member 31 and the sliding member 36 to slide smoothly.
[0033] On the basis of the above scheme, since the lock housing 1 is also provided with a square tongue 2, and the lock housing 1 is also provided with a linkage member 4 for promoting the linkage between the square tongue 2 and the oblique tongue 6, the linkage member 4 can be used to promote the synchronous lifting and lowering of the oblique tongue 6 and the square tongue 2, so as to facilitate the smooth unlocking of the lock body.
[0034] Specifically, the linkage member 4 is connected to the transmission arm 5 rotatably connected in the lock housing 1 through the transmission sheet 11, and the rotation of the linkage member 4 causes the transmission arm 5 to drive the square tongue 2 to slide upward or downward in the lock housing 1; one side of the transmission arm 5 is rotatably mounted on the shaft pin 10 provided on the lock housing 1, and the other end of the transmission arm 5 is adaptively connected to the protrusion 9 provided on the square tongue 2. Among them, the transmission arm 5 and the transmission sheet 11 are gear transmission. Therefore, the transmission sheet 11 can be used to reliably transmit the power of the linkage member 4 to the square tongue 2 to ensure that the square tongue 2 is smoothly raised and lowered in the lock housing 1. Specifically, when the handle on the door body rotates, the linkage member 4 is driven to rotate. At this time, the linkage member 4 and the transmission arm 5 are gear-driven, and one side of the transmission arm 5 is rotatably connected to the shaft pin 10, and the other end of the transmission arm 5 is connected to the protrusion 9, so it can be ensured that the transmission arm 5 transmits the power of the handle to the square tongue 2 to achieve the extension or retraction of the square tongue 2.
[0035] Furthermore, since the first paddle 12 is provided on one side of the linkage member 4, and the second paddle 13 is provided on the other side of the linkage member 4, and the ends of the first paddle 12 and the second paddle 13 away from the linkage member 4 abut against the upper surface of the baffle 8, the rotation of the linkage member 4 can drive the two paddles to rotate, and when the paddles rotate, the oblique tongue 6 can be promoted to rise and fall in the lock housing 1, so that the square tongue 2 and the oblique tongue 6 of the lock can move synchronously, so as to facilitate the unlocking of the lock.
[0036] Furthermore, since the transmission sheet 11 is connected to the linkage member 4 through the polygonal hole 16, wherein the polygonal hole 16 includes a first transmission surface 14 and a second transmission surface 15, and the extension lines of the first transmission surface 14 and the second transmission surface 15 facing each other form an angle, and the angle value of the angle is 5-15°. Therefore, the transmission sheet 11 has enough free movement space outside the linkage member 4, that is, after the linkage member 4 is subjected to force, it needs to rotate a certain angle before the side of the linkage member 4 can contact the transmission surface; due to the setting of the free movement space, when the linkage rod 7 slides vertically upward, the two paddles will not interfere with and affect its smooth upward sliding, so that the linkage rod 7 can slide smoothly to the outside of the lock housing 1, so that the inclined tongue 6 is completely separated from the inclined tongue hole.
[0037] The above is a detailed description of the embodiments of the present invention in conjunction with 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.
