Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] This embodiment relates to a latch, as shown in the reference... Figures 1-3The lock body includes a lock body 100, a bolt 200, and a lock cylinder 300. The lock body 100 has a cavity 170; one side of the lock body 100 has an assembly opening 110 communicating with the cavity 170. One end of the bolt 200 is movably fitted between the assembly opening 110 and the cavity 170; the lock cylinder 300 is fitted onto the lock body 100. The lock cylinder 300 includes a pressing member 310, a lock cylinder 300 body, and a locking member 330. The lock cylinder 300 body is connected to both sides of the pressing member 310. The locking member 330 is located on the other side of the pressing member 310 and extends into the cavity 170. The locking member 330 is used to engage with one end of the bolt 200 to lock the bolt 200. A guide member 120 is provided within the cavity 170, located on both sides of the assembly opening 110. The guide member 120 is used to spread the locking member 330 to both sides. Pressing the pressing member 310 causes the locking member 330 to be pushed open to both sides by the guide member 120, thereby separating the locking member 330 from the bolt 200 to unlock the bolt 200. Specifically, in this embodiment, the mounting opening 110 is located on the lower side of the lock body 100, and the lock head 300 is mounted on the upper side of the lock body 100. The locking member 330 is located on the back side of the pressing member 310 and on the upper side of the guide member 120. The locking member 330 has a certain degree of elasticity. The bolt 200 is often connected to items that need to be locked or prevented from being opened. When the user needs to unlock the bolt 200, simply press down on the pressing member 310. At this time, the locking member 330 is pushed open to both sides by the guide member 120, that is, the locking member 330 releases its engagement with the bolt 200, and the two separate. After the bolt 200 loses the engagement of the locking member 330, it automatically moves away from the end of the locking member 330 under the action of gravity, thus unlocking the bolt 200. When the user needs to lock the bolt 200, simply move the end of the bolt 200 that is movably assembled between the assembly port 110 and the cavity 170 toward the locking member 330, that is, toward the pressing member 310, so that the locking member 330 engages with the bolt 200. The overall structure of this lock is simple. Unlocking only requires pressing the pressing part 310, and self-locking only requires moving one end of the bolt 200 toward the locking part 330 so that the locking part 330 engages with the bolt 200. The unlocking and self-locking operations are simple, saving users time and improving the user experience.

[0031] Furthermore, the lock cylinder 300 also includes an elastic shaft 340, through which the two sides of the pressing member 310 are connected to the lock cylinder 300 body. In this embodiment, the elastic design of the elastic shaft 340 allows it to deform, further enabling the pressing member 310 to have a certain downward pressing space. On the one hand, this allows the latching member 330 to move downwards to be opened by the guide post; on the other hand, it provides a pushing force to the bolt 200 to move away from the latching member 330, causing the bolt 200 to separate from the latching member 330. After the pressing member 310 completes the unlocking operation, the elasticity of the elastic shaft 340 allows the pressing member 310 to automatically reset, preparing for the next unlocking operation and ensuring the continuous normal use of the lock.

[0032] In some embodiments, refer to Figures 3-5 The latching member 330 has a first latching portion 331 at one end facing the bolt 200, and second latching portions 210 on both sides of one end of the bolt 200 that mate with the first latching portion 331. The engagement of the first latching portion 331 on the latching member 330 with the second latching portions 210 on the bolt 200 makes the engagement between the bolt 200 and the lock head 300 more secure and reliable. This engagement effectively prevents the bolt 200 from accidentally disengaging from the lock body 100 during use, improving the security of the lock and facilitating unlocking.

[0033] Furthermore, a limiting portion 130 is provided at the end of the cavity 170 away from the latching member 330 and on both sides of the assembly opening 110. The limiting portion 130 cooperates with the second latching portion 210 to prevent the bolt 200 from separating from the lock body 100. The limiting portion 130 restricts the range of movement of the bolt 200, preventing the bolt 200 from moving excessively away from the latching member 330 or from falling off between the cavity 170 and the assembly opening 110, resulting in the loss of the bolt 200.

[0034] Furthermore, the first latching part 331 is provided with a first guide slope 3311; the side of the second latching part 210 is provided with a second guide slope 211 that cooperates with the first guide slope 3311. The cooperation between the first guide slope 3311 and the second guide slope 211 makes it easier for the locking tongue 200 to engage with the latching part 330, reducing the installation difficulty and improving the assembly efficiency.

[0035] Reference Figure 3 The guide member 120 has a third guide slope 121 that mates with the first guide slope 3311 on the side that abuts against the first latching part 331. The interaction between the first guide slope 3311 and the third guide slope 121 allows the latching member 330 to be opened to both sides more smoothly, reducing the occurrence of jamming and improving the smoothness of unlocking.

[0036] In some embodiments, the end of the latch 200 near the pressing member 310 is provided with an abutment post 220 extending toward the pressing member 310; when the free end of the abutment post 220 abuts against the side of the pressing member 310 near the latch 200, one end of the latch 200 engages with the locking member 330. When the latch 200 is moved toward the locking member 330, and the free end of the abutment post 220 abuts against the side of the pressing member 310 near the latch 200, one end of the latch 200 engages with the locking member 330. The abutment post 220 serves as a buffer and positioning element, reminding the user that further insertion is not necessary, ensuring the accurate relative position between one end of the latch 200 and the locking member 330. Simultaneously, the abutment post 220 also buffers the impact force generated when the latch 200 is inserted, reducing damage to the pressing member 310 and other components, and improving the durability of the latch. Specifically, two abutment posts 220 are provided, and the free ends of the two abutment posts 220 are inclined in an arc towards the middle position of the two abutment posts 220. When the inclined abutment posts 220 are subjected to impact force, they will undergo a certain degree of elastic deformation. This elastic deformation can absorb and buffer the impact force, and play a better buffering role.

[0037] In this embodiment, refer to Figure 3 as well as Figure 5 A guide rail 140 is provided on one side of the cavity 170, and a guide groove 230 is provided on the latch 200 to cooperate with the guide rail 140. The cooperation between the guide rail 140 and the guide groove 230 restricts the movement trajectory of the latch 200 between the assembly port 110 and the cavity 170, which is more conducive to the engagement of the latch 200 with the snap-fit ​​part 330, and also facilitates the unlocking of the latch 200.

[0038] In this embodiment, the lock head 300 is detachably mounted on the lock body 100, facilitating timely replacement of damaged individual parts and reducing maintenance costs. Specifically, the lock head 300 is snap-fitted onto the lock body 100. Furthermore, the lock body 100 has an insertion groove 150 at one end near the lock head 300 for inserting the lock head 300, maintaining the tightness of the overall lock structure and making the overall structure more concise. In this embodiment, the pressing member 310 protrudes from the outside of the insertion groove 150, facilitating user pressing to unlock.

[0039] Furthermore, referring to Figures 5-6 A protrusion 160 is provided inside the lock body 100 and on the periphery of the insertion groove 150. A locking hole 350 is provided on the lock head 300 to engage with the protrusion 160. The engagement of the locking hole 350 with the protrusion facilitates the assembly of the lock head 300 and the lock body 100 and prevents the lock head 300 from loosening or falling off during use. Specifically, the protrusion 160 also has a guide slope to facilitate the insertion of the locking hole 350.

[0040] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
