Description

Technical Field

[0001] This utility model relates to the field of door and window control hardware, and in particular to a lock body and lock. Background Technology

[0002] In existing lock body technology, a lock body can be composed of basic units such as a housing, a bolt, and a drive component. The drive component has a sliding groove structure, and the bolt engages with this groove. The movement of the drive component controls the extension and retraction of the bolt. To ensure bolt transmission accuracy and locking function, the groove is generally designed with a free travel section and an effective travel section. However, in existing technologies, the effective travel section of the drive component's sliding groove structure is usually linear. This means that when the driving force is constant, the locking force transmitted from the drive component to the bolt is also a fixed value. Furthermore, in the entire door and window system, the lock body needs to cooperate with the lock seat to achieve locking and sealing of the door and window. However, there is an installation distance between the lock body and the lock seat. The travel before the bolt extends and contacts the lock seat is the free travel; the travel from contact until the bolt is fully extended is the loaded travel. Only after the bolt contacts the lock seat does the driving force truly become an effective locking force.

[0003] The locking force transmitted to the bolt is directly related to the slope of the groove on the drive component. The larger the slope of the groove, the smaller the locking force transmitted to the bolt. The slope of the groove is affected by the effective travel of the drive component and the extension distance of the bolt. When the effective travel of the drive component and the extension distance of the bolt are restricted by the structure, the slope of the groove is often too large, resulting in a smaller locking force. Therefore, the driving force must be increased to achieve the required locking force, which leads to a poor user experience. Utility Model Content

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] Reference Figures 2 to 12As shown, this invention illustrates an embodiment of the lock body 1. The lock body 1 includes a bolt 11 and a drive component 12. The drive component 12 is provided with a slide groove 121 that is slidably connected to the bolt 11. The slide groove 121 is used to drive the bolt to extend or retract. The slide groove 121 includes an effective travel segment 1211 that extends obliquely along the width direction of the drive component 12. The effective travel segment 1211 includes an unloaded travel segment 12111 and a loaded travel segment 12112. One end of the loaded travel segment 12112 is connected to one end of the unloaded travel segment 12111, and the other end of the loaded travel segment 12112 extends obliquely in the opposite direction to the other end of the unloaded travel segment 12111. The slope of the loaded travel segment 12112 is less than the slope of the unloaded travel segment 12111.

[0042] Specifically, refer to Figure 1 As shown, in the field of doors and windows, the lock body 1 and the lock seat 2 cooperate to achieve the locking function. Under normal circumstances, the lock seat 2 is located on one side of the lock body 1 and is adjacent to the lock body 1 so that the lock tongue 11 of the lock body 1 can lock with the lock seat 2. In order to ensure the smooth opening and closing of the doors and windows, the lock tongue 11 can extend and retract inside the lock body 1. The extension and retraction of the lock tongue 11 is related to the external driving force. In the prior art, the effective stroke section 1211 of the slide groove 121 structure of the driving component 12 of the lock body 1 is usually straight and the slope of the effective stroke section 1211 is large, resulting in a small locking force of the lock body 1. At this time, more driving force is required. In order to save effort for the user when driving the lock tongue 11 to extend and retract, this application provides a lock body 1 to achieve the effect of saving effort.

[0043] The lock body 1 includes a drive component 12 and a latch 11, which are slidably connected. The drive component 12 is used to drive the latch 11 to extend and retract, and the latch 11 is used to cooperate with the lock seat 2 to achieve the locking function. The drive component 12 is provided with a slide groove 121, which extends obliquely from the side of the drive component 12 away from the lock seat 2 toward the side of the drive component 12 closer to the lock seat 2. The slide groove 121 is slidably connected to the latch 11 so that when the drive component 12 moves, it can drive the latch 11 to slide along the opening direction of the slide groove 121, thereby driving the latch 11 to extend and retract relative to the lock seat 2.

[0044] The slide groove 121 includes an effective travel section 1211, which refers to the travel segment in which the bolt 11 can slide within the slide groove 121. The effective travel section 1211 extends obliquely from the side of the drive component 12 away from the lock seat 2 towards the side of the drive component 12 closer to the lock seat 2. That is, the effective travel section 1211 is obliquely arranged along the width direction of the drive component 12. The bolt 11 reciprocates along the opening direction of the effective travel section 1211, thereby allowing the bolt 11 to extend and retract relative to the lock seat 2. The effective travel section 1211 includes an unloaded travel section 12111 and a loaded travel section 12112. The unloaded travel section 12111 refers to the travel segment in which the bolt 11 can slide within the lock body 1 and the lock seat 2 due to the installation distance between them. The unloaded travel segment 12111 refers to the travel segment from when the bolt 11 extends out and before it contacts the lock seat 2, which slides along the slide groove 121. The loaded travel segment 12112 refers to the travel segment from when the bolt 11 contacts the lock seat 2 until the bolt 11 is fully extended. One end of the unloaded travel segment 12111 is connected to one end of the loaded travel segment 12112, and the other end of the loaded travel segment 12112 extends in the opposite direction to the other end of the unloaded travel segment 12111. When the locking function of the lock seat 2 and the lock body 1 is realized, the drive component 12 is activated to move, so as to drive the bolt 11 to slide along the unloaded travel segment 12111 to the loaded travel segment 12112, and slide along the loaded travel segment 12112 until the bolt 11 is fully locked with the lock seat 2.

[0045] When the drive unit 12 is activated to move the latch 11 from the unloaded travel segment 12111 to the loaded travel segment 12112, the latch 11 extends towards the lock seat 2 until it locks with the lock seat 2. When the drive unit 12 is activated to move the latch 11 from the loaded travel segment 12112 to the unloaded travel segment 12111, the latch 11 retracts away from the lock seat 2 until it is no longer in contact with the lock seat 2, thus unlocking the lock.

[0046] According to the principle of force decomposition, under the same driving force, the greater the slope of the effective travel segment 1211, the smaller the locking force obtained after decomposition, and vice versa. Therefore, to increase the locking force between the bolt 11 and the lock seat 2, thereby reducing the user's driving force, the slope of the load travel segment 12112 is set to be less than the slope of the unloaded travel segment 12111. When the slope of the load travel segment 12112 is less than the slope of the unloaded travel segment 12111, there is a significant change in the transition slope between the unloaded travel segment 12111 and the load travel segment 12112. The locking force of the bolt 11 increases after contacting the lock seat 2, that is, the locking force of the bolt 11 in the load travel segment 12112 is greater than the locking force of the bolt 11 in the unloaded travel segment 12111, which reduces the user's driving force, thereby achieving a labor-saving effect and improving the user experience.

[0047] For example, when a user closes a door or window, a total locking force of 100N is required. If the slope of the load stroke segment 12112 is small, the operator may only need a driving force of 20N to achieve a locking force of 100N. If the slope of the load stroke segment 12112 is large, it may require a force of 50N or more to achieve a locking force of 100N.

[0048] This application further subdivides the effective travel segment 1211 into an unloaded travel segment 12111 and a loaded travel segment 12112, with the slope of the loaded travel segment 12112 being less than that of the unloaded travel segment 12111. When the locking tongue 11 slides from the unloaded travel segment 12111 to the loaded travel segment 12112, the locking force of the locking tongue 11 increases when sliding in the loaded travel segment 12112, thereby reducing the user's driving force, achieving a labor-saving effect, and improving the user experience.

[0049] In one embodiment, the effective stroke segment 1211 includes a plurality of sequentially connected load stroke segments 12112 (not shown in the figure), and the slope of the plurality of load stroke segments 12112 is inclined from large to small in the direction from near the unloaded stroke segment 12111 to away from the unloaded stroke segment 12111. Specifically, the effective travel segment 1211 can be divided into two or more segments. When the effective travel segment 1211 has two segments, it consists of an unloaded travel segment 12111 and a loaded travel segment 12112. In this case, the slope of the unloaded travel segment 12111 is greater than the slope of the loaded travel segment 12112, and the loaded travel segment 12112 is located on the side closer to the lock seat 2. When the effective travel segment 1211 has several segments, it consists of an unloaded travel segment 12111 and several loaded travel segments 12112, and the several loaded travel segments 12112 are connected sequentially, with the slope of the several loaded travel segments 12112 decreasing sequentially towards the lock seat 2. The drive component 12 is inclined to one side. That is, after several load stroke segments 12112 are connected, the end connected to the unloaded stroke segment 12111 gradually and gently extends towards the side of the drive component 12 closer to the lock seat 2. The transition slope between the unloaded stroke segment 12111 and the load stroke segment 12112 changes significantly, so that the overall slope of the several load stroke segments 12112 is still less than the slope of the unloaded stroke segment 12111. This ensures that the locking force of the bolt 11 increases when it slides through the several load stroke segments 12112, further improving the structural stability of the lock body 1 and the stability of the bolt 11 when it slides through the several load stroke segments 12112.

[0050] More specifically, the unloaded travel segment 12111 and the loaded travel segment 12112 are either straight or curved. The shapes of the unloaded travel segment 12111 and the loaded travel segment 12112 can be straight or curved, and there is no limitation here, as long as the overall slope of the loaded travel segment 12112 is less than the overall slope of the unloaded travel segment 12111. This allows the drive component 12 to be manufactured according to actual needs, thereby improving the practicality of the lock body 1.

[0051] In a specific embodiment, refer to Figures 2 to 6 As shown, the slide 121 also includes two limiting stroke sections 1212, which are respectively connected to the two ends of the effective stroke section 1211. The extending direction of the limiting stroke section 1212 is parallel to the length direction of the drive component 12. Specifically, the slide 121 also includes two limiting travel sections 1212. These limiting travel sections 1212 restrict the extension / retraction movement of the bolt 11 towards or away from the lock seat 2. The two limiting travel sections 1212 are respectively connected to both ends of the effective travel section 1211. The effective travel section 1211 includes an unloaded travel section 12111 and a loaded travel section 12112. One end of the unloaded travel section 12111 is connected to one end of the loaded travel section 12112; that is, one limiting travel section 1212 is connected to the other end of the unloaded travel section 12111, and the other limiting travel section 1212 is connected to the other end of the loaded travel section 12112. In this embodiment, to ensure that the bolt 11 only extends or retracts within the effective travel section 1211, it is designed to move towards or away from the lock seat 2. Therefore, the extension direction of the limiting stroke segment 1212 is parallel to the length direction of the drive component 12. That is, the two limiting stroke segments 1212 are set horizontally along the length direction of the drive component 12. When the latching part 111 of the lock tongue 11 is located in the limiting stroke segment 1212, the lock tongue 11 does not extend or retract, nor does it move left or right. During the entire operation, the lock tongue 11 can only extend or retract within the effective stroke segment 1211, thereby ensuring the fixation of the no-load stroke and the load stroke of the lock tongue 11. The no-load stroke is before the lock tongue 11 extends and contacts the lock seat 2. The load stroke is from the time the lock tongue 11 contacts the lock seat 2 until the lock tongue 11 is fully extended. This improves the locking stability of the lock tongue 11 and the lock seat 2, improves the structural stability of the lock body 1, and improves the accuracy of user operation.

[0052] In one embodiment, reference is made to Figures 3 to 8As shown, the latch 11 has a locking portion 111, which protrudes from one side of the latch 11 toward the slide groove 121 and is slidably connected to the slide groove 121. Specifically, the latch 11 is slidably connected to the slide groove 121. To ensure stable sliding of the latch 11, a locking portion 111 is also provided on the latch 11. The locking portion 111 protrudes from one side of the latch 11 toward the slide groove 121, that is, the locking portion 111 protrudes outward from the surface of the latch 11. The locking portion 111 is cylindrical, and the diameter of the locking portion 111 is adapted to the width of the slide groove 121. The latch 11 is located on one side of the drive component 12, and the protruding direction of the locking portion 111 faces toward the slide groove 121. In terms of direction, during assembly, the snap-fit ​​part 111 is embedded in the slide groove 121, and the snap-fit ​​part 111 is slidably connected to the slide groove 121. Therefore, when the drive component 12 moves, it can drive the snap-fit ​​part 111 to slide along the opening direction of the slide groove 121, thereby causing the entire bolt 11 to perform a telescopic movement relative to the lock seat 2. In this embodiment, the snap-fit ​​part 111 makes the bolt 11 slide more stably and smoothly along the slide groove 121, while preventing the bolt 11 from disengaging from the drive component 12, thus improving the structural stability of the lock body 1.

[0053] When the locking part 111 is located in the limit stroke section 1212 of the slide groove 121, the drive component 12 is activated, and the locking tongue 11 will not perform telescopic movement relative to the lock seat 2; when the locking part 111 is located in the effective stroke section 1211 of the slide groove 121, the drive component 12 is activated, and the locking tongue 11 will perform telescopic movement relative to the lock seat 2.

[0054] More specifically, the latching part 111 on the latch 11 can be integrally formed with the latch 11, or it can be assembled from another part, which is not limited here.

[0055] In a specific embodiment, refer to Figure 10 As shown, the lock body 1 also includes a housing assembly 13. The housing assembly 13 has an internal receiving groove 137. The drive component 12 and the bolt 11 are movably connected to the housing assembly 13 within the receiving groove 137. Specifically, the housing assembly 13 is used to protect and support other structural components of the lock body 1. The receiving groove 137 is used to accommodate other structural components of the lock body 1, namely, the drive component 12 and the bolt 11 are disposed within the receiving groove 137. The drive component 12 and the bolt 11 are movably connected to the housing assembly 13 within the receiving groove 137. The drive component 12 and the bolt 11 are movably connected via a sliding groove 121. Therefore, when the drive component 12 moves within the receiving groove 137, it drives the bolt 11 to perform a telescopic movement, thereby improving the stability of the movement of the drive component 12 and the bolt 11, preventing external factors from affecting the movement of the drive component 12 and the bolt 11, and improving the structural stability of the lock body 1.

[0056] In one embodiment, reference is made to Figure 4As shown, a limiting groove 131 is provided on one side of the housing assembly 13 parallel to the driving component 12. The limiting groove 131 extends vertically along the width direction of the housing assembly 13, and one end of the engaging portion 111 is slidably connected to the limiting groove 131. Specifically, the housing assembly 13 is also provided with a limiting groove 131, which is located on one side of the housing assembly 13 parallel to the driving component 12, that is, the limiting groove 131 is located at the upper or lower end of the driving component 12, and the limiting groove 131 extends vertically along the width direction of the housing assembly 13, that is, the limiting groove 131 extends vertically from the side of the housing assembly 13 away from the lock seat 2 towards the side closer to the lock seat 2; when assembling the latch 11, the driving component 12, and the housing assembly 13, the latch 11 and the driving component 12 are both placed inside the housing assembly 13, and the engaging portion 111 of the latch 11 passes through the sliding groove of the driving component 12. 121 is slidably connected to the limiting groove 131 of the housing assembly 13, and / or, one end of the locking part 111 is slidably connected to the limiting groove 131, and the other end of the locking part 111 is slidably connected to the slide groove 121. Therefore, when the driving component 12 moves, it drives the lock tongue 11 to slide along the opening direction of the slide groove 121, and the limiting groove 131 limits the lock tongue 11 to move closer to or away from the lock seat 2 in the extension direction of the limiting groove 131. Thus, the lock tongue 11 moves closer to or away from the lock seat 2 as a whole under the drive of the driving component 12, so as to realize the locking function or unlocking function of the lock body 1 and the lock seat 2.

[0057] In this embodiment, the limiting groove 131 is used to restrict the extension and retraction of the latch 11 in a specified direction, thereby further ensuring that the latch 11 moves closer to or away from the lock seat 2 along the vertical direction of the housing assembly 13, restricting the movement direction of the latch 11, thereby improving the accuracy and smoothness of the latch 11 sliding.

[0058] In one embodiment, reference is made to Figure 5 As shown, the inner wall of the housing assembly 13 is provided with a fixed shaft 132 facing the receiving groove 137, and the fixed shaft 132 is rotatably connected to one end of the latch 11. Specifically, the housing assembly 13 is provided with a fixed shaft 132, which protrudes from the inner wall of the housing assembly 13 toward the receiving groove 137, and the fixed shaft 132 is rotatably connected to one end of the latch 11. This allows the latch 11 to rotate around the fixed shaft 132 toward or away from the lock seat 2 when the driving component 12 drives the latch 11 to slide, thereby causing the latch 11 to perform a telescopic movement relative to the lock seat 2. In this embodiment, the latch 11 telescopic movement is a rotary telescopic movement, thereby improving the applicability of the lock body 1.

[0059] More specifically, the fixed shaft 132 is disposed on one side of the housing assembly 13 parallel to the drive component 12 and extends perpendicular to one side of the housing assembly 13 toward the receiving groove 137; the drive component 12 is also provided with a clearance groove 123, which is horizontally disposed along the length direction of the drive component 12. The clearance groove 123 is slidably connected to the fixed shaft 132, wherein one end of the fixed shaft 132 passes through the clearance groove 123 and is rotatably connected to one end of the locking tongue 11, and the other end of the locking tongue 11 is slidably connected to the slide groove 121. Therefore, when the drive component 12 moves, it drives the locking tongue 11 to perform a telescopic movement relative to the lock seat 2 around the fixed shaft 132 along the opening direction of the slide groove 121.

[0060] More specifically, one end of the locking tongue 11 is provided with a through hole 112, which is rotatably connected to the fixed shaft 132.

[0061] In a specific embodiment, refer to Figure 9 and Figure 10 As shown, the housing assembly 13 also has a through hole 133, which is located on the side of the housing assembly 13 facing the lock seat 2 and is used to avoid the bolt 11. Specifically, the housing assembly 13 has a through hole 133 on the side facing the lock seat 2. The through hole 133 connects the receiving groove 137 and the lock seat 2, so that the bolt 11 can pass through the through hole 133 to make telescopic movement relative to the lock seat 2, so as to ensure the movement of the bolt 11 and realize the locking and unlocking functions of the bolt 11 and the lock seat 2.

[0062] More specifically, the housing assembly 13 includes a front panel 134, a bottom shell 135, and a front shell 136. The front panel 134, the bottom shell 135, and the front shell 136 together form a receiving groove 137. The front panel 134 is located near the lock seat 2 and is perpendicularly connected to the bottom shell 135 and the front shell 136. A through hole 133 is provided on the front panel 134, and a limiting groove 131 and a fixing shaft 132 are provided on the bottom shell 135 or the front shell 136. The structure of the housing assembly 13 is simple.

[0063] In one embodiment, reference is made to Figure 2 As shown, the drive component 12 also has a drive part 122, which is located on one side of the drive component 12 and is used to initiate the movement of the drive component 12. Specifically, the drive component 12 moves by its own movement to drive the locking tongue 11 to move, thus initiating the movement of the drive component 12. The drive component 12 also has a drive part 122, which is located on one side of the drive component 12. The drive part 122 can be used to connect other components to push the drive component 12, or it can directly push the drive component 12. There is no limitation here. The structure of the drive component 12 is simple.

[0064] In another embodiment (not shown in the figure), the lock body 1 includes a drive component 12 and a bolt 11. The bolt 11 is provided with a slide groove 121 that is slidably connected to the drive component 12. The slide groove 121 is used to drive the bolt to extend or retract. The slide groove 121 includes an effective travel segment 1211 that extends obliquely along the width direction of the drive component 12. The effective travel segment 1211 includes an unloaded travel segment 12111 and a loaded travel segment 12112. One end of the loaded travel segment 12112 is connected to one end of the unloaded travel segment 12111, and the other end of the loaded travel segment 12112 extends obliquely in the opposite direction to the other end of the unloaded travel segment 12111. The slope of the loaded travel segment 12112 is less than the slope of the unloaded travel segment 12111.

[0065] Specifically, refer to Figure 1 As shown, in the field of doors and windows, the lock body 1 and the lock seat 2 cooperate to achieve the locking function. Under normal circumstances, the lock seat 2 is located on one side of the lock body 1 and is adjacent to the lock body 1 so that the lock tongue 11 of the lock body 1 can lock with the lock seat 2. In order to ensure the smooth opening and closing of the doors and windows, the lock tongue 11 can extend and retract inside the lock body 1. The extension and retraction of the lock tongue 11 is related to the external driving force. In the prior art, the effective stroke section 1211 of the slide groove 121 structure of the driving component 12 of the lock body 1 is usually straight and the slope of the effective stroke section 1211 is large, resulting in a small locking force of the lock body 1. At this time, more driving force is required. In order to save effort for the user when driving the lock tongue 11 to extend and retract, this application provides a lock body 1 to achieve the effect of saving effort.

[0066] The lock body 1 includes a drive component 12 and a latch 11, which are slidably connected. The drive component 12 is used to drive the latch 11 to extend and retract, and the latch 11 is used to cooperate with the lock seat 2 to achieve the locking function. The latch 11 is provided with a slide groove 121, which is used to limit the extension or retraction of the latch 11, so that when the drive component 12 moves, it can drive the latch 11 to slide along the opening direction of the slide groove 121, thereby driving the latch 11 to extend and retract relative to the lock seat 2.

[0067] The slide groove 121 includes an effective travel section 1211, which refers to the travel segment in which the bolt 11 can slide within the slide groove 121. The effective travel section 1211 is inclined along the width direction of the drive component 12, and the bolt 11 reciprocates along the opening direction of the effective travel section 1211, thereby allowing the bolt 11 to extend and retract relative to the lock seat 2. The effective travel section 1211 includes an unloaded travel section 12111 and a loaded travel section 12112. The unloaded travel section 12111 refers to the travel segment in which the bolt 11 slides along the slide groove 121 after it extends out and before it contacts the lock seat 2 due to the installation distance between the lock body 1 and the lock seat 2. The loaded travel section 1211... 2 refers to the travel segment from when the bolt 11 contacts the lock seat 2 until the bolt 11 is fully extended; one end of the unloaded travel segment 12111 is connected to one end of the loaded travel segment 12112, and the other end of the loaded travel segment 12112 extends in the opposite direction to the other end of the unloaded travel segment 12111. The loaded travel segment 12112 is located on the side of the drive component 12 close to the lock seat 2. Thus, when the locking function of the lock seat 2 and the lock body 1 is realized, the drive component 12 is activated to move, so that the bolt 11 slides along the unloaded travel segment 12111 to the loaded travel segment 12112, and slides along the loaded travel segment 12112 until the bolt 11 is fully locked to the lock seat 2.

[0068] When the drive unit 12 is activated to move the latch 11 from the unloaded travel segment 12111 to the loaded travel segment 12112, the latch 11 extends towards the lock seat 2 until it locks with the lock seat 2. When the drive unit 12 is activated to move the latch 11 from the loaded travel segment 12112 to the unloaded travel segment 12111, the latch 11 retracts away from the lock seat 2 until it is no longer in contact with the lock seat 2, thus unlocking the lock.

[0069] According to the principle of force decomposition, under the same driving force, the greater the slope of the effective travel segment 1211, the smaller the locking force obtained after decomposition, and vice versa. Therefore, to increase the locking force between the bolt 11 and the lock seat 2, thereby reducing the user's driving force, the slope of the load travel segment 12112 is set to be less than the slope of the unloaded travel segment 12111. When the slope of the load travel segment 12112 is less than the slope of the unloaded travel segment 12111, there is a significant change in the transition slope between the unloaded travel segment 12111 and the load travel segment 12112. The locking force of the bolt 11 increases after contacting the lock seat 2, that is, the locking force of the bolt 11 in the load travel segment 12112 is greater than the locking force of the bolt 11 in the unloaded travel segment 12111, which reduces the user's driving force, thereby achieving a labor-saving effect and improving the user experience.

[0070] For example, when a user closes a door or window, a total locking force of 100N is required. If the slope of the load stroke segment 12112 is small, the operator may only need a driving force of 20N to achieve a locking force of 100N. If the slope of the load stroke segment 12112 is large, it may require a force of 50N or more to achieve a locking force of 100N.

[0071] This application further subdivides the effective travel segment 1211 into an unloaded travel segment 12111 and a loaded travel segment 12112, with the slope of the loaded travel segment 12112 being less than that of the unloaded travel segment 12111. When the locking tongue 11 slides from the unloaded travel segment 12111 to the loaded travel segment 12112, the locking force of the locking tongue 11 increases when sliding in the loaded travel segment 12112, thereby reducing the user's driving force, achieving a labor-saving effect, and improving the user experience.

[0072] In one embodiment, the effective stroke segment 1211 includes a plurality of sequentially connected load stroke segments 12112 (not shown in the figure), and the slope of the plurality of load stroke segments 12112 is inclined from large to small in the direction from near the unloaded stroke segment 12111 to away from the unloaded stroke segment 12111. Specifically, the effective travel segment 1211 can be divided into two or more segments. When the effective travel segment 1211 has two segments, it consists of an unloaded travel segment 12111 and a loaded travel segment 12112. In this case, the slope of the unloaded travel segment 12111 is greater than the slope of the loaded travel segment 12112, and the loaded travel segment 12112 is located on the side closer to the lock seat 2. When the effective travel segment 1211 has several segments, it consists of an unloaded travel segment 12111 and several loaded travel segments 12112, and the several loaded travel segments 12112 are connected sequentially, with the slope of the several loaded travel segments 12112 decreasing from large to small. The segments are arranged to extend at an angle toward one side of the bolt 11. That is, after several load stroke segments 12112 are connected, the end connected by the unloaded stroke segment 12111 gradually and gently extends toward the side of the bolt 11 closer to the lock seat 2. The transition slope between the unloaded stroke segment 12111 and the load stroke segment 12112 changes significantly, so that the overall slope of the several load stroke segments 12112 is still less than the slope of the unloaded stroke segment 12111. This ensures that the locking force of the bolt 11 increases when it slides through the several load stroke segments 12112, further improving the structural stability of the lock body 1 and the stability of the bolt 11 when it slides through the several load stroke segments 12112.

[0073] More specifically, the unloaded travel segment 12111 and the loaded travel segment 12112 are either straight or curved. The shapes of the unloaded travel segment 12111 and the loaded travel segment 12112 can be straight or curved, and there is no limitation here, as long as the overall slope of the loaded travel segment 12112 is less than the overall slope of the unloaded travel segment 12111. This allows the drive component 12 to be manufactured according to actual needs, thereby improving the practicality of the lock body 1.

[0074] In a specific embodiment, refer to Figures 2 to 6 As shown, the slide 121 also includes two limiting stroke sections 1212, which are respectively connected to the two ends of the effective stroke section 1211. The extending direction of the limiting stroke section 1212 is parallel to the length direction of the drive component 12. Specifically, the slide groove 121 also includes two limiting travel sections 1212. These limiting travel sections 1212 restrict the bolt 11 from extending or retracting towards the lock seat 2. The two limiting travel sections 1212 are respectively connected to both ends of the effective travel section 1211. The effective travel section 1211 includes an unloaded travel section 12111 and a loaded travel section 12112. One end of the unloaded travel section 12111 is connected to one end of the loaded travel section 12112; that is, one limiting travel section 1212 is connected to the other end of the unloaded travel section 12111, and the other limiting travel section 1212 is connected to the other end of the loaded travel section 12112. In this embodiment, to ensure that the bolt 11 only extends or retracts towards or away from the lock seat 2 within the range of the effective travel section 1211, Therefore, the extension direction of the limiting stroke segment 1212 is parallel to the length direction of the driving component 12. That is, the two limiting stroke segments 1212 are set horizontally along the length direction of the driving component 12. When the driving component 12 drives the bolt 11 to move along the limiting stroke segment 1212, the bolt 11 does not extend or retract, nor does it move left or right. During the entire operation, the bolt 11 can only extend or retract within the effective stroke segment 1211, thereby ensuring the fixation of the no-load stroke and the load stroke of the bolt 11. The no-load stroke is before the bolt 11 extends and contacts the lock seat 2. The load stroke is from the time the bolt 11 contacts the lock seat 2 until the bolt 11 is fully extended. This improves the locking stability of the bolt 11 and the lock seat 2, improves the structural stability of the lock body 1, and improves the accuracy of user operation.

[0075] In one embodiment, the driving component 12 is provided with a locking portion 111 (not shown in the figure). The locking portion 111 protrudes from one side of the driving component 12 toward the slide groove 121, and the locking portion 111 is slidably connected to the slide groove 121. Specifically, the driving component 12 is slidably connected to the slide groove 121. To ensure the stable sliding of the locking tongue 11, the driving component 12 is also provided with a locking portion 111. The locking portion 111 protrudes from one side of the driving component 12 toward the slide groove 121, that is, the locking portion 111 protrudes outward from the surface of the driving component 12. The locking portion 111 is cylindrical, and the diameter of the locking portion 111 is adapted to the width of the slide groove 121. The locking tongue 11 is located on one side of the driving component 12, and the protruding direction of the locking portion 111 faces the slide groove 121. In the direction of 1, during assembly, the snap-fit ​​part 111 is embedded in the slide groove 121, and the snap-fit ​​part 111 is slidably connected to the slide groove 121. Therefore, when the drive component 12 moves, the snap-fit ​​part 111 drives the bolt 11 to move along the opening direction of the slide groove 121, thereby causing the bolt 11 to perform a telescopic movement relative to the lock seat 2. In this embodiment, the snap-fit ​​part 111 makes the bolt 11 slide more stably and smoothly along the slide groove 121, while preventing the bolt 11 from disengaging from the drive component 12, thus improving the structural stability of the lock body 1.

[0076] When the locking part 111 is located in the limit stroke section 1212 of the slide groove 121, the drive component 12 is activated, and the locking tongue 11 will not perform telescopic movement relative to the lock seat 2; when the locking part 111 is located in the effective stroke section 1211 of the slide groove 121, the drive component 12 is activated, and the locking tongue 11 will perform telescopic movement relative to the lock seat 2.

[0077] More specifically, the snap-fit ​​portion 111 on the drive component 12 may be integrally formed with the drive component 12, or it may be composed of another component, which is not limited here.

[0078] In a specific embodiment, refer to Figure 10 As shown, the lock body 1 also includes a housing assembly 13. The housing assembly 13 has an internal receiving groove 137. The drive component 12 and the bolt 11 are movably connected to the housing assembly 13 within the receiving groove 137. Specifically, the housing assembly 13 is used to protect and support other structural components of the lock body 1. The receiving groove 137 is used to accommodate other structural components of the lock body 1, namely, the drive component 12 and the bolt 11 are disposed within the receiving groove 137. The drive component 12 and the bolt 11 are movably connected to the housing assembly 13 within the receiving groove 137. The drive component 12 and the bolt 11 are slidably connected via a sliding groove 121. Therefore, when the drive component 12 moves within the receiving groove 137, it drives the bolt 11 to perform a telescopic movement, thereby improving the stability of the movement of the drive component 12 and the bolt 11, preventing external factors from affecting the movement of the drive component 12 and the bolt 11, and improving the structural stability of the lock body 1.

[0079] In one embodiment, the housing assembly 13 has a limiting groove 131 (not shown in the figure) on one side parallel to the drive component 12. The limiting groove 131 extends vertically along the width direction of the housing assembly 13. The locking tongue also has a limiting part, which is slidably connected to the limiting groove 131. Specifically, the housing assembly 13 is also provided with a limiting groove 131. The limiting groove 131 is provided on one side of the housing assembly 13 parallel to the driving component 12, that is, the limiting groove 131 is located at the upper or lower end of the driving component 12, and the limiting groove 131 extends vertically along the width direction of the housing assembly 13, that is, the limiting groove 131 extends vertically from the side of the housing assembly 13 away from the lock seat 2 toward the side closer to the lock seat 2. The limiting groove 131 is used to limit the extension and retraction movement of the lock tongue 11. The lock tongue is also provided with a limiting part, which protrudes from one side of the lock tongue 11 toward the limiting groove 131. The limiting part is used to slide with the limiting groove 131 to improve the stability of the movement of the lock tongue 11.

[0080] When assembling the latch 11, drive component 12, and housing assembly 13, the latch 11 and drive component 12 are both placed inside the housing assembly 13. The limiting part is slidably connected to the limiting groove 131. When the drive component 12 moves, it drives the latch 11 to slide along the opening direction of the slide groove 121. The limiting groove 131 limits the latch 11 to move closer to or away from the lock seat 2 in the extension direction of the limiting groove 131. Thus, the latch 11 moves closer to or away from the lock seat 2 as a whole under the drive of the drive component 12, so as to realize the locking or unlocking function of the lock body 1 and the lock seat 2.

[0081] In this embodiment, the limiting groove 131 is used to restrict the extension and retraction of the latch 11 in a specified direction, thereby further ensuring that the latch 11 moves closer to or away from the lock seat 2 along the vertical direction of the housing assembly 13, restricting the movement direction of the latch 11, thereby improving the accuracy and smoothness of the latch 11 sliding.

[0082] In one embodiment, reference is made to Figure 5 As shown, the inner wall of the housing assembly 13 is provided with a fixed shaft 132 facing the receiving groove, and the fixed shaft 132 is rotatably connected to one end of the latch 11. Specifically, the housing assembly 13 is provided with a fixed shaft 132, which protrudes from the inner wall of the housing assembly 13 toward the receiving groove, and the fixed shaft 132 is rotatably connected to one end of the latch 11. This allows the latch 11 to rotate around the fixed shaft 132 toward or away from the lock seat 2 when the driving component 12 drives the latch 11 to slide, thereby causing the latch 11 to perform a telescopic movement relative to the lock seat 2. In this embodiment, the latch 11 telescopic movement is a rotary telescopic movement, thereby improving the applicability of the lock body 1.

[0083] More specifically, the fixed shaft 132 is disposed on one side of the housing assembly 13 parallel to the drive component 12 and extends perpendicular to one side of the housing assembly 13 toward the receiving groove 137; the drive component 12 is also provided with a clearance groove 123, which is horizontally disposed along the length direction of the drive component 12 and is slidably connected to the fixed shaft 132. One end of the fixed shaft 132 passes through the clearance groove 123 and is rotatably connected to one end of the locking tongue 11. The other end of the locking tongue 11 is slidably connected to the drive component 12. Therefore, when the drive component 12 moves, it drives the locking tongue 11 to perform a telescopic movement relative to the lock seat 2 around the fixed shaft 132 along the opening direction of the slide groove 121.

[0084] More specifically, one end of the locking tongue 11 is provided with a through hole 112, which is rotatably connected to the fixed shaft 132.

[0085] In a specific embodiment, refer to Figure 9 and Figure 10 As shown, the housing assembly 13 also has a through hole 133, which is located on the side of the housing assembly 13 facing the lock seat 2 and is used to avoid the bolt 11. Specifically, the housing assembly 13 has a through hole 133 on the side facing the lock seat 2. The through hole 133 connects the receiving groove 137 and the lock seat 2, so that the bolt 11 can pass through the through hole 133 to make telescopic movement relative to the lock seat 2, so as to ensure the movement of the bolt 11 and realize the locking and unlocking functions of the bolt 11 and the lock seat 2.

[0086] More specifically, the housing assembly 13 includes a front panel 134, a bottom shell 135, and a front shell 136. The front panel 134, the bottom shell 135, and the front shell 136 together form a receiving groove 137. The front panel 134 is located near the lock seat 2 and is perpendicularly connected to the bottom shell 135 and the front shell 136. A through hole 133 is provided on the front panel 134, and a limiting groove 131 and a fixing shaft 132 are provided on the bottom shell 135 or the front shell 136. The structure of the housing assembly 13 is simple.

[0087] In one embodiment, reference is made to Figure 2 As shown, the drive component 12 also has a drive part 122, which is located on one side of the drive component 12 and is used to initiate the movement of the drive component 12. Specifically, the drive component 12 moves by its own movement to drive the locking tongue 11 to move, thus initiating the movement of the drive component 12. The drive component 12 also has a drive part 122, which is located on one side of the drive component 12. The drive part 122 can be used to connect other components to push the drive component 12, or it can directly push the drive component 12. There is no limitation here. The structure of the drive component 12 is simple.

[0088] Reference Figures 10 to 11As shown, this embodiment also provides a lock, which includes a lock body 1. The lock body 1 can be any type of lock body 1 provided by this utility model. Since the specific structure and working principle of the lock body 1 have been described in detail in the previous description, they will not be repeated here for the sake of brevity.

[0089] The lock in this embodiment uses the lock body 1 provided by this utility model. The lock body 1 has a large locking force, which makes it easier for users to unlock or lock the lock, thus improving the user experience and the practicality of the lock.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
