Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, specifically to a two-way anti-fall concealed handle. Background Technology
[0002] In the field of interior door and window design, in pursuit of a simple and elegant appearance, the application of concealed handles is becoming increasingly common. This means that the handle structure is hidden inside the window sash to reduce the interference of exposed parts on the overall visual effect.
[0003] For example, the technical solution disclosed in application number 202320958022.3 is a hidden handle. When opening, the upper part of the handle needs to be pressed down to raise the lower handle position. This operation method is extremely inconvenient for people who wear manicures and can easily cause damage to the manicure or hand discomfort.
[0004] For example, technical solution 2020212300633 discloses a concealed handle. In its normal state, the handle's flange is locked below the positioning plate's stop. During use, pressing the positioning plate causes one end of the positioning plate to move downwards in contact with the return spring, moving the stop upwards. The contact area between the stop and the flange decreases until the flange disengages from the stop, and the handle springs up under the force of the spring at the other end, opening to a fully open position. Pulling the handle moves the component it is fixed to. However, this technical solution requires pressing down a lower switch for the handle to spring up when unlocking, which could easily injure the hand or nails of users unfamiliar with the product's operation.
[0005] In conclusion, while existing concealed handle structures can achieve the goal of hiding the handle, they have certain limitations in terms of ease of operation and safety of use, and therefore need to be improved. Utility Model Content

[0047] In this embodiment, the first anti-fall member 6 is provided with a first shoulder 61 for engaging in the first positioning groove 13, and the groove wall of the first guide groove 51 is provided with a first guide opening 53 penetrating the side of the fork 5, through which the first shoulder 61 protrudes out of the fork 5; the second anti-fall member 7 is provided with a second shoulder 71 for engaging in the second positioning groove 14, and the groove wall of the second guide groove 52 is provided with a second guide opening 54 penetrating the side of the fork 5, through which the second shoulder 71 protrudes out of the fork 5.
[0048] In this embodiment, one end of the bracket 3 is provided with a linkage protrusion 30 that slides into the slide groove 12. The linkage groove 31 is provided on the linkage protrusion 30. The two opposite groove walls of the linkage groove 31 are respectively provided with a first linkage part 34 and a second linkage part 35. The first driving inclined surface 32 is provided on the first linkage part 34. The groove wall of the first guide groove 51 is provided with a first notch 55 that penetrates the side of the fork 5 and is used to avoid the first linkage part 34. The second driving inclined surface 33 is provided on the second linkage part 35. The groove wall of the second guide groove 52 is provided with a second notch 56 that penetrates the side of the fork 5 and is used to avoid the second linkage part 35.
[0049] In this embodiment, the first anti-fall component 6 is provided with a first mating inclined surface 62 for cooperating with the first driving inclined surface 32, and the second anti-fall component 7 is provided with a second mating inclined surface 72 for cooperating with the second driving inclined surface 33. The first mating inclined surface 62 and the second mating inclined surface 72 are both inclined surfaces and form an "eight" shape between them. The first driving inclined surface 32 and the second driving inclined surface 33 are both inclined surfaces and form an "eight" shape between them, so as to facilitate their linkage.
[0050] In this embodiment, the bracket 3 is connected to a sliding base plate 10 located outside the outer shell 1. The sliding base plate 10 slides with the outer surface of the outer shell 1. The bracket 3 and the sliding base plate 10 are connected by bolts. For example, the linkage protrusion 30 extends into the sliding groove 12. A first screw 100 threaded in the screw hole of the linkage protrusion 30 is inserted at the bottom of the sliding base plate 10. Furthermore, the sliding base plate 10 is provided with a sliding clearance opening 101 for the pull fork 5 to pass through, so that the bracket 3 can remain in a state that can slide relative to the pull fork 5.
[0051] In this embodiment, the bracket 3 is provided with a sliding rotation groove 36, the handle 2 is provided with a swing rotation groove 21, one end of the push rod 4 is inserted into the sliding rotation groove 36 and is hinged to the bracket 3 by a first fixed shaft 200, and the other end is inserted into the swing rotation groove 21 and is hinged to the handle 2 by a second fixed shaft 300, thereby realizing the transmission between the bracket 3, the push rod 4 and the handle 2.
[0052] In this embodiment, the bracket 3 is provided with a spring-loaded sound-dampening component 400 for engaging with the handle 2 when it retracts into the groove 11. The spring-loaded sound-dampening component 400 is made of elastic rubber, which prevents the handle 2 from colliding with the bracket 3 after retracting into the groove 11, thereby improving the service life of the concealed handle and reducing noise. Furthermore, the bracket 3 is provided with a sliding insertion hole 37, and the spring-loaded sound-dampening component 400 is provided with a sound-dampening plug that inserts into the sliding insertion hole 37, thus completing the purpose of installing the spring-loaded sound-dampening component 400 on the bracket 3. Additionally, when the handle 2 is pressed against the spring-loaded sound-dampening component 400, a second operating space is left between the handle 2 and the bracket 3, making it convenient for the user to hook onto the handle 2 and operate it.
[0053] In this embodiment, one end of the handle 2 is provided with a second handle protrusion 22, and the second handle protrusion 22 is provided with a handle rotation through hole. The outer shell 1 is provided with a handle mounting shaft 500 that passes through the handle rotation through hole. Furthermore, both ends of the handle rotation through hole are fitted with bushings 600 that are fitted on the handle mounting shaft 500, thereby reducing friction when the handle 2 rotates. Even further, the outer shell 1 is provided with a handle mating through hole corresponding to the handle rotation through hole, and the handle mounting shaft 500 is a rivet that passes through the handle mating through hole and is riveted to the outer shell 1.
[0054] In this embodiment, when the handle 2 is locked, it is entirely located within the groove 11. A first operating space 700 is left between the other end of the handle 2 and the other end of the groove 11, which facilitates the user's fingers to insert into the groove 11 and pull the handle 2, improving the user's ease of operation. Furthermore, when the handle 2 is locked, an operating recess 23 is provided on the side facing the groove 11, and a second operating space is left between the handle 2 and the bracket 3, which facilitates the user's fingers to hook on the handle 2 and pull the handle 2, improving the user's experience of operating the handle 2.
[0055] Reference Figure 2 , Figure 5 and Figure 6 When the hidden handle is locked, the handle 2 is closed and flush with the surface of the outer shell 1. The first anti-fall component 6 is lifted upward by the spring force of the first spring 8, and the first shoulder 61 falls into the first positioning groove 13 of the outer shell 1, so that the outer shell 1 and the first anti-fall component 6 cooperate to lock the fork 5, thus playing an anti-fall role. At this time, the second anti-fall component 7 is pressed by the second driving inclined surface 33 on the left side of the bracket 3 and sinks to the bottom surface of the outer shell 1, so that it is disengaged from the second positioning groove 14 of the outer shell 1.
[0056] Reference Figure 7-9 When the hidden handle is unlocked, pull up the handle 2. The handle 2 pulls the bracket 3 to the left through the hinged push rod 4. The first driving inclined surface 32 of the bracket 3 presses the first anti-falling component 6 down, causing it to disengage from the first positioning groove 13 of the outer shell 1 and release the anti-falling state. Continue to pull the bracket 3 to the left, causing the fork 5 to slide to the left. When the bracket 3 slides to the second positioning groove 14 of the outer shell 1, the second anti-falling component 7 is springed up by the spring force of the second spring 9, causing the fork 5 to lock with the outer shell 1, achieving the anti-falling state. At the same time, the other end of the handle 2 remains extended out of the groove 11.
[0057] Reference Figure 10-12 When the handle is locked, the hinged push rod 4 pushes the bracket 3 to slide to the right. The second drive inclined surface 33 of the bracket 3 presses against the second anti-falling component 7, causing it to slide down to the bottom surface of the outer shell 1 and disengage from the second positioning groove 14 of the outer shell 1. The fork 5 is released from the anti-falling state. The bracket 3 continues to slide to the right until the first anti-falling component 6 springs up into the first positioning groove 13 of the outer shell 1 under the action of the spring force of the first spring 8. At this time, the handle 2 is closed and the fork 5 is in the anti-falling state.
[0058] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
