A lever handle overlock mechanism

Abstract

This utility model relates to a handle hook-type locking mechanism, including a vertically arranged handle body and a mounting base. The lower end of the handle body is connected to the mounting base via a rotating component, and the rotating component is connected to a transmission component for controlling the movement of the latch. It also includes a drive component connected to the mounting base, which is operably disposed within the mounting base and configured to lock the movement state of the transmission component when operated. This utility model achieves locking functionality using a single-latch lock body, with a simple structure that easily enables locking and unlocking. Furthermore, the combination of a small-radius rounded corner rotating body, a stop block, and a second spring increases the step difference, resulting in a stronger sense of sudden resistance and providing a distinct tactile feedback when locking or unlocking. This step difference design also physically locks the rotating body, preventing the slider's abutment and the hook's rotating shaft from loosening under vibration.

Description

Technical Field

[0001] This utility model relates to the field of hardware lock technology, specifically a handle hook-type locking mechanism. Background Technology

[0002] Push-pull handles are mechanisms that open and close doors by pushing or pulling the handle to control the extension and retraction of the latch. Currently, most existing push-pull handle mechanisms are configured with a single-latch lock body, and most of these single-latch lock bodies lack a locking function. Some push-pull handle mechanisms are configured with a double-latch lock body, where the normal opening and closing of the door is achieved by controlling the movement of the bevel latch, and the locking is achieved by controlling the movement of the square latch. However, double-latch lock bodies usually have complex structures. For example, invention patent CN109629911A discloses a push-pull door lock structure including a bevel latch and a square latch, which has a complex cooperation and transmission system to achieve both opening / closing and locking. How to simplify the existing push-pull handle locking structure and incorporate a locking function into a single-latch lock body is an urgent problem to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a handle hook-type locking mechanism, which aims to provide a locking solution suitable for push-pull handle single-tongue lock bodies.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handle hook-type locking mechanism, comprising a vertically arranged handle body and a mounting base, wherein the lower end of the handle body is connected to the mounting base via a rotating component, and the rotating component is connected to a transmission component for controlling the movement of the latch bolt, and further comprising: a drive component connected to the mounting base, wherein the drive component is operably disposed within the mounting base and is configured to lock the movement state of the transmission component when operated.

[0005] In a preferred embodiment, the mounting base includes a mounting top and a mounting base, which cooperate to form an installation space. The rotating component includes a connecting end and a rotating end. The connecting end is connected to the handle body, and the rotating end extends into the installation space and is rotatably connected to a transmission component installed in the installation space.

[0006] In a preferred embodiment, the transmission assembly includes a rotating shaft that rotatably engages with the rotating end and a paddle, the paddle extending into the rotating end and rotatably connected to the rotating shaft.

[0007] In a preferred embodiment, the drive assembly includes a guide block fixedly connected to the mounting top, a slider slidably connected to the guide block, and a steering hook. The paddle passes through the guide block and the slider and is configured to move synchronously with the slider. The steering hook is operably disposed within the mounting space and is configured to engage with the slider when operated to restrict the slider's sliding movement.

[0008] In a preferred embodiment, the guide block abuts against the rotating end, and the guide block is provided with a first rectangular through hole that allows the paddle to pass through. The paddle is movably disposed in the first rectangular through hole, and the slider is provided with a second rectangular through hole that matches the paddle specification.

[0009] In a preferred embodiment, the guide block has two guide grooves distributed vertically on the side facing the mounting base, and a bearing block protruding from the surface of the guide block is fixedly connected in the guide groove; the slider has two sliding grooves corresponding to the positions of the guide grooves, and the bearing block extends into the sliding grooves.

[0010] In a preferred embodiment, the slider is further provided with a sliding block matching the guide groove on the side facing the guide block, and the sliding block corresponds to the upper and lower ends of the groove respectively.

[0011] In a preferred embodiment, a first spring is connected between the sliding block and the bearing block.

[0012] In a preferred embodiment, the steering hook is disposed below the guide block and includes a hook rotation shaft, a stop block, and a second spring; the hook rotation shaft includes a rotating body and a hook body fixed to one side thereof, the hook body being configured to engage with the slider when operated; the stop block abuts against one side of the rotating body, and the second spring is connected between the stop block and the mounting top.

[0013] In a preferred embodiment, the outer periphery of the rotating body is constructed as a rectangular structure, and the four corners of the rectangular structure are rounded, with the radius of the rounded corners set to 1-3 mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) The handle hook locking mechanism provided by this utility model can achieve the locking function by using a single tongue lock body, and the structure is simple. The locking and unlocking functions can be easily achieved by the structure of the guide block, slider and steering hook of the drive component. At the same time, it can also meet the locking and unlocking functions by using the lock cylinder and key, effectively improving the user experience.

[0016] 2) By using a rounded rotating body with a smaller radius and the combination of a stop and a second spring, the step difference is increased, and the resistance change is stronger, so that the user will have a clear tactile sensation when locking or unlocking the door, thereby improving the user experience. On the other hand, the step difference design can physically lock the rotating body, thereby preventing the slider's attachment part and the hook rotation shaft from loosening under vibration.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] See Figures 1-4 This embodiment discloses a handle hook-type locking mechanism, including a vertically arranged handle body 1 and a mounting base 2. The lower end of the handle body 1 is connected to the mounting base 2 via a rotating member 3, and the rotating member 3 is connected to a transmission component for controlling the movement of the latch bolt. The mounting base 2 is also connected to a drive component for interacting with the outside world. This drive component is operably disposed within the mounting base 2 and is configured to lock the movement state of the transmission component when operated by the user, thereby controlling the rotation state of the rotating member 3.

[0030] Understandably, the door lock handle body 1 and the corresponding mounting base 2 and internal components are set into two sets, which are installed on the inner and outer sides of the door respectively. Since the structures on both sides are roughly the same (only the locking knob and lock cylinder structures are different), for the sake of simplicity, this embodiment only introduces the structure on one side.

[0031] Specifically, the handle body 1 has a protrusion fixed at its lower end, and this protrusion has a mounting groove for connecting the rotating component 3, such as... Figure 4 As shown, in this embodiment, the rotating component 3 includes a connecting end 31 and a rotating end 32. The connecting end 31 is inserted into the mounting groove and fastened with screws, while the rotating end 32 is installed in the mounting base 2.

[0032] Mounting base 2 includes mounting top 21 and mounting base (not shown in the figure). Mounting top 21 and mounting base are connected by screws, and the two cooperate to form an installation space. The rotating end 32 of rotating component 3 extends into the installation space, and the transmission component is disposed in the installation space.

[0033] See Figure 5The transmission assembly includes a rotating shaft 41 rotatably connected to the rotating end 32 of the rotating component 3, and a lever 42 connected to the rotating end 32. Specifically, the mounting top 21 has a mounting opening adapted to the rotating end 32. The rotating end 32 of the rotating component 3 extends into the mounting opening and further into the mounting space. The rotating end 32 has a central through hole that rotatably engages with the rotating shaft 41. The rotating shaft 41 is inserted into the central through hole, thereby rotatably connecting the rotating component 3 to the rotating shaft 41. The mounting top 21 has slots for mounting the rotating shaft 41, and both ends of the rotating shaft 41 are engaged in the corresponding slots. Pushing the handle inward or pulling the handle outward can drive the connecting end 31 of the rotating component 3 to move up and down, thereby enabling the rotating component 3 to rotate slightly up and down synchronously with the rotating shaft 41 as the fulcrum.

[0034] Combination Figure 4 The rotating end 32 has an opening groove 321 on the side facing the mounting base 22 that is adapted to the paddle 42. The paddle 42 extends into the opening groove 321, and one end of it is rotatably connected to the rotating shaft 41. The rotating end 32 can drive the paddle 42 to move synchronously by rotating up and down, thereby realizing the driving cooperation with the tongue. The driving cooperation structure of the paddle 42 and the tongue is the prior art, and this embodiment will not describe the structure again.

[0035] See Figure 1 , Figure 5 The drive assembly is also located within the installation space, including a guide block 5 fixedly connected to the mounting top 21, a slider 6 slidably connected to the guide block 5, and a steering hook 8. The paddle 42 passes through the guide block 5 and the slider 6 and moves synchronously with the slider 6. The steering hook 8 is operably located within the installation space and is configured to engage with the slider 6 when operated, thereby achieving the effect of braking the movement of the slider 6 and the paddle 42.

[0036] For details, see Figure 6 The guide block 5 is generally constructed as a rectangular block structure, which abuts against the rotating end 32 on the side near the mounting base. The guide block 5 has a first rectangular through hole 51 with dimensions larger than the opening slot 321 at the position corresponding to the opening slot 321. The paddle 42 passes through the first rectangular through hole 51, and the first rectangular through hole 51 does not restrict the movement of the paddle 42. The guide block 5 has two guide grooves 52 distributed vertically on the side facing the mounting base. The two guide grooves 52 are spaced apart, and a bearing block 53 protruding from the surface of the guide block 5 is fixedly connected in the guide groove 52.

[0037] The slider 6 is connected to the guide block 5 on the side facing the mounting base, and it is slidably connected within the guide groove 52. For details, see [link to documentation]. Figure 7The slider 6 further includes an integrally connected sliding part 61 and a hanging part 62. The sliding part 61 is generally constructed as a rectangular plate structure, and it has two sliding grooves 63 corresponding to the positions of the two guide grooves. The bearing block 53 extends into the sliding groove 63 and can guide the up and down sliding of the slider 6. Furthermore, the sliding part 61 has a sliding block 64 matching the guide groove 52 on the side facing the guide block 5. The sliding block 64 corresponds to the upper and lower ends of the sliding groove 63 respectively. Through the cooperation of the sliding groove 63 and the bearing block 53 and the cooperation of the sliding block 64 and the guide groove 52, the movement of the slider 6 can be made more stable.

[0038] The sliding part 61 is provided with a second rectangular through hole 65 that is compatible with the specifications of the paddle 42 at the position corresponding to the first rectangular through hole 51. The paddle 42 passes through the second rectangular through hole 65 and can drive the slider 6 to move synchronously through the cooperation of the second rectangular through hole 65.

[0039] The drive assembly further includes a first spring 7 connected between the slider 64 and the support block 53, which resets the slider 6 when the paddle 42 is not under force.

[0040] The attachment part 62 is integrally connected to the bottom of the sliding part 61 and is used to cooperate with the steering hook 8.

[0041] See Figure 1 , Figure 8 The steering hook 8 is located below the guide block 5 and includes a hook rotation shaft 81, a stop block 82, and a second spring 83. The hook rotation shaft 81 is rotatable and includes a rotating body 811 and a hook body 812 fixed to one side thereon. Correspondingly, the mounting base and the mounting top 21 are both provided with mounting slots that fit the shape of the rotating body 811. The rotating body 811 is embedded in the mounting slot and can rotate relative to the mounting slot. In this embodiment, the hooking part 62 is constructed as a hookable opening that fits the structure of the steering hook 8, such as... Figure 1 When unlocked, the steering hook 8 disengages from the abutment part 62, at which point the slider 6 can rise and fall synchronously with the lever 42; Figure 2 When locked, the steering hook 8 is inserted into the abutment part 62, thereby restricting the movement of the slider 6. At this time, the paddle 42 cannot move.

[0042] In this embodiment, the rotating body 811 has a straight-line insertion hole 813 at its center. This insertion hole 813 is used to cooperate with the lock cylinder and knob of the door lock for user interaction. For example, the outer lock cylinder or the inner knob of the door lock is connected to the same insertion plate 9. The insertion plate 9 is inserted into the insertion hole 813. Rotating the lock cylinder with a key or rotating the knob can drive the insertion plate 9 to rotate, thereby causing the hook rotating shaft 81 to rotate.

[0043] The stop block 82 abuts against one side of the rotating body 811. The mounting top seat 21 is provided with a guide groove matching the stop block 82, and a second spring 83 connected to the end of the stop block 82 is fixed in the guide groove. Through the action of the second spring 83, the stop block 82 is always abutted against the rotating body 811. It should be noted that in this embodiment, the outer periphery of the rotating body 811 is constructed as a rectangular structure, and the four corners of the rectangular structure are rounded. The radius of the rounded corners is set to 1-3mm. When the rotating body 811 rotates, the rounded corners of the edges press against the stop block 82, causing it to shift and simultaneously compressing the second spring 83. When the rotating body 811 rotates 90° to its final position, the second spring 83 releases energy instantaneously, causing the stop block 82 to return to its original position. In this embodiment, the combination of the rounded rotating body 811 with a specific small radius, the stop block 82, and the second spring 83 increases the step difference and makes the resistance change stronger, so that the user will have a clear tactile sensation when locking or unlocking the door, thereby improving the user experience. On the other hand, the step difference design forms a physical lock on the rotating body 811, which can prevent the hook part 62 of the slider 6 and the hook rotation shaft 81 from loosening under vibration.
