Description

Technical Field

[0001] The utility model relates to the field of door and window accessories, in particular to a handle lock structure with a dual anti-falling function. Background Art

[0002] Chinese Patent Authorization Publication No. CN220151089U discloses a technical solution entitled "A Door and Window Hook Lock." To limit the position of the hook lock housing and prevent it from falling, the following assembly structure is employed: An outwardly protruding elastic member is provided on the hook lock base facing the hook lock housing. The hook lock housing is provided with a position-limiting recess that cooperates with the elastic member. The position-limiting recess is used to limit the elastic member when the elastic member moves to the position of the position-limiting recess. The hook lock base is provided with an elastic member slideway, which has a first opening facing the hook lock housing. A spring and a ball are disposed within the elastic member slideway. The ball is lifted out of the first opening by the spring. The spring and ball constitute the elastic member.

[0003] Among them, because the hook lock shell is a shell, the thickness of the hook lock shell is limited, and in order to avoid affecting the movement of the hook lock shell, a shallow limiting recess is generally used; in addition, the limiting recess is for the spherical ball to be embedded, so the limiting strength of the limiting recess acting on the elastic member is limited, which will lead to limited anti-fall performance of the hook lock shell.

[0004] At the same time, the end of the spring is placed on the ball in the elastic member formed by the spring pressing the ball. Since the movement of the hook lock housing generates frictional force that drives the ball to roll, and the rolling ball generates friction on the spring that causes it to distort and deform. As a result, the elastic force of the spring can easily decrease after a period of use, causing the elastic force of the spring on the ball to decrease or even disappear, which in turn can easily lead to the anti-fall performance of the hook lock housing being reduced or even disappearing. This can easily cause the hook lock housing to loosen, which can bring a very bad user experience.

[0005] Therefore, it is very necessary to design a handle lock structure with a dual anti-fall function to solve the above technical problems. Utility Model Content

[0031] like Figures 1 to 6 As shown, the utility model describes a handle lock structure with a dual anti-fall function, comprising a toggle lock shell 1, a guide seat 2, and a fork body 3, wherein the guide seat 2 is provided with an anti-fall hole 21 and an elastic top-pressing body 22, the toggle lock shell 1 can be slidably mounted on the guide seat 2 up and down, and the elastic top-pressing body 22 elastically presses on the toggle lock shell 1, the fork body 3 is arranged on the inner wall of the toggle lock shell 1, and an elastic hook 4 is provided on the fork body 3, and the elastic hook 4 can be hooked on the anti-fall hole 21 after sliding with the toggle lock shell 1.

[0032] In this handle lock structure, not only can the elastic top-pressing body 22 be used to produce the friction anti-falling effect, but the elastic hook 4 and the anti-falling hole 21 can also be used to cooperate to achieve the anti-falling effect. In this way, the handle lock structure can have a dual anti-falling function, which can have better anti-falling performance and will not become loose even after long-term use. This can help maintain a high user experience for a long time, and it can have higher reliability and applicability.

[0033] In actual use, the guide seat 2 is fixed on the door leaf or door frame, which can limit the lock shell 1 to the door leaf or door frame. When the lock shell 1 is toggled by hand, the fork body 3 can be moved, and the fork body 3 can move the related lock body, thereby meeting the needs of actual use.

[0034] In actual use, the handle lock structure is not limited to use on conventional doors and windows, it can also be used on cabinet doors, such as wardrobe doors, cabinet doors, display cabinet doors, electrical cabinet doors, equipment cabinet doors and other products with cabinet doors.

[0035] like Figures 2 to 10 As shown, the fork body 3 includes an integrally formed fork head 31 and a reinforcement seat 32. The inner end of the fork head 31 is connected to the reinforcement seat 32. The elastic hook 4 is disposed on the reinforcement seat 32, and the reinforcement seat 32 is fixed to the inner wall of the toggle lock housing 1. This not only ensures high structural strength of the fork body 3, but also ensures high structural strength at the installation point of the elastic hook 4, which helps to improve structural strength and durability.

[0036] like Figure 9As shown, the reinforcing seat 32 is composed of a block with a large length, width and height, so that it can meet the reinforcement function and provide a very reasonable installation space for the elastic hook 4.

[0037] like Figure 4 and Figure 9 As shown, waist-shaped holes 321 are formed at both ends of the reinforcing seat 32 , and locking screws 322 are passed through the two waist-shaped holes 321 to fix the two ends of the reinforcing seat 32 on the inner wall of the toggle lock housing 1 .

[0038] like Figures 2 to 5 As shown, the guide base 2 is provided with a through-hole 23, through which the shift fork head 31 is disposed. This eliminates the need to reserve space between the lock housing 1 and the guide base 2 for the shift fork head 31 to pass through, thereby facilitating the manufacture of a more compact handle lock structure and thus helping to expand its scope of application.

[0039] like Figure 3 、 Figure 5 and Figure 11 As shown, a clearance groove 24 is provided on the inner wall of the guide base 2, the clearance hole 23 is formed through the clearance groove 24, and the anti-fall hole 21 is formed on the edge of the notch of the clearance groove 24. This not only facilitates the manufacture of the guide base 2, but also makes the handle lock structure more compact, thereby facilitating the manufacture of a smaller handle structure, thereby helping to further expand the scope of application of the handle lock structure.

[0040] like Figure 10 As shown, the shift fork head 31 includes a reinforcement strip 311 and two shift fork strips 312 arranged side by side in a vertical direction. One end of the two shift fork strips 312 is connected to the reinforcement base 32, and the reinforcement strip 311 is formed between the ends of the two shift fork strips 312 near the reinforcement base 32. This not only makes the shift fork head 31 simple and reliable, but also controls the use of raw materials. In addition, an open shift fork notch 313 is formed between the other ends of the two shift fork strips 312, which facilitates assembly, matching, and disassembly of the lock and the shift fork head 31, thereby improving the convenience of installation, disassembly, and maintenance.

[0041] like Figure 4 、 Figures 7 to 10As shown, the side wall of the shift fork body 3 is provided with a receiving groove 33 for the elastic hook 4 to retract into. A first spring 34 is provided in the receiving groove 33. One end of the elastic hook 4 is movably inserted into the receiving groove 33, and the elastic hook 4 is elastically pressed against the first spring 34. The inner wall of the shift lock housing 1 is provided with a guide portion 35 for guiding the elastic hook 4 to retract into the receiving groove 33. When the elastic hook 4 moves downward, it can be blocked by the lower hole edge of the anti-fall hole 21 and guided by the guide portion 35 and retracted into the receiving groove 33. This not only provides a very stable and reliable anti-fall effect, but also makes it easy to release the hook state of the elastic hook 4, thereby facilitating the normal pulling requirements of the handle lock structure, and thus can well meet the needs of actual use, which helps to further improve the applicability of the handle lock structure.

[0042] The elastic hook 4 is hooked on the anti-falling hole 21 in a buckle manner, thus meeting the anti-falling function.

[0043] like Figures 4 to 8 As shown, the elastic hook 4 is a rectangular block structure. A limiting groove 41 is provided on the surface of the elastic hook 4 facing the bottom of the receiving groove 33. One end of the first spring 34 is positioned in the limiting groove 41 and elastically presses against the bottom of the limiting groove 41. A supporting inclined surface 42 is provided on the upper side of the other end of the elastic hook 4. The guide portion 35 is a guiding inclined surface with the same inclination direction as the supporting inclined surface 42, and the supporting inclined surface 42 abuts against the guide portion 35. This not only ensures a more stable and reliable anti-fall effect, but also allows the anti-fall effect of the elastic hook 4 to be easily released, thereby making it more stable and convenient to use. The cooperation between the supporting inclined surface 42 and the guide portion 35 not only achieves the purpose of stable and accurate positioning of the elastic hook 4, but also facilitates the stable guidance of the elastic hook 4 to flip and retract into the receiving groove 33, thus ensuring extremely convenient use.

[0044] like Figure 4 As shown, a limiting protrusion 36 is provided on the inner wall of the toggle lock housing 1, and the guide portion 35 is provided on the side wall of the limiting protrusion 36. This can help the guide portion 35 to play a more stable guiding role, thereby helping to further improve the performance.

[0045] like Figure 8 and Figure 10 As shown, the limiting groove 41 is a notch-shaped groove that passes horizontally through the elastic hook 4, and the upper and lower groove bottoms of the receiving groove 33 are respectively provided with avoidance holes 331. The two avoidance holes 331 can respectively allow the upper and lower elastic hooks 4 of the limiting groove 41 to enter. This not only helps to make the structure more compact, but also helps to ensure that the first spring 34 and the elastic hook 4 can stably achieve the elastic effect.

[0046] like Figure 7 、 Figure 9 and Figure 10 As shown, a limiting groove 37 is formed on the side wall of the fork body 3. The limiting groove 37 is located in the middle of the receiving groove 33 and is wider than the receiving groove 33. The first spring 34 is placed in the limiting groove 37. The diameter of the first spring 34 is larger than the width of the receiving groove 33. This helps the first spring 34 to stably exert its elastic effect, thereby further improving reliability.

[0047] like Figure 2 、 Figure 4 and Figure 12 As shown, the guide base 2 is provided with at least one vertical guide hole 25, and the inner wall of the toggle lock housing 1 is provided with guide posts 11 equal in number to the guide holes 25 and corresponding in position to each other. The guide posts 11 are slidably fitted into the guide holes 25. This not only enables the toggle lock housing 1 to be assembled with the guide base 2 more stably and accurately, but also improves the accuracy and stability of the toggle lock housing 1, thereby further helping to further enhance the performance of the handle lock structure.

[0048] like Figure 2 and Figure 4 As shown, the guide hole 25 is a waist-shaped countersunk hole that penetrates the guide base 2, with the small end of the guide hole 25 facing the inner wall of the toggle lock housing 1. The guide post 11 is slidably embedded in the small end of the guide hole 25. A limit screw 26 is arranged in the large end of the guide hole 25, and the diameter of the nut end of the limit screw 26 is larger than the width of the small end of the guide hole 25. The limit screw 26 is also threaded onto the guide post 11. This not only more stably restrains the toggle lock housing 1 on the guide base 2, but also facilitates a compact structure of the handle lock structure, which helps to further improve the applicability of the handle lock structure.

[0049] like Figure 3 and Figure 4 As shown, a rubber buffer block 5 is provided between the upper inner wall of the toggle lock housing 1 and the top surface of the guide seat 2, and between the lower inner wall of the toggle lock housing 1 and the top surface of the guide seat 2. This allows the rubber buffer blocks 5 to provide cushioning and shock absorption when the toggle lock housing 1 approaches the top or bottom surface of the guide seat 2, thereby reducing noise and aging, thereby improving the performance of the handle lock structure.

[0050] like Figure 3 and Figure 4 As shown, the upper and lower buffer rubber blocks 5 are respectively embedded in the upper and lower surfaces of the guide seat 2, which not only helps to achieve the purpose of stably installing the buffer rubber blocks 5, but also enables the buffer rubber blocks 5 to stably play a buffering and shock-absorbing role.

[0051] like Figure 3 and Figure 4As shown, the inner wall of the toggle lock housing 1 is provided with at least two positioning grooves 12 arranged vertically side by side. The elastic pressing body 22 includes a second spring 221 and a ball 222. The second spring 221 and the ball 222 are sequentially embedded in the guide seat 2, and the ball 222 can be embedded in the positioning groove 12 under the elastic force of the second spring 221. Such an elastic pressing body 22 can stably achieve the positioning effect, thereby ensuring its high stability and reliability. In the actual manufacturing process, the elastic pressing body 22 can be formed by a spring sheet with elastic protrusions, and the elastic protrusion is embedded in the positioning groove 12; in addition, the elastic pressing body 22 can also be formed by an elastic rubber block. In this way, the elastic pressing requirements of the elastic pressing body 22 can be met.

[0052] like Figure 2 and Figure 4 As shown, the rear wall of the guide base 2 is provided with a locking groove 27. A locking block 28 with a countersunk hole 281 is disposed within the locking groove 27. A locking ring groove 282 is formed on the outer circumference of the locking block 28, surrounding the countersunk hole 281. A set screw 29 is threaded onto the guide base 2, allowing the inner end of the set screw 29 to fit into the locking groove 27. The toggle lock housing 1 is provided with a mounting hole 13 extending through the outer end of the set screw 29. This not only ensures stable positioning of the guide base 2 but also facilitates assembly and disassembly. The countersunk hole 281 allows a screw to pass through, allowing the locking block 28 to be secured in the desired position. The assembled assembly of the toggle lock housing 1, guide base 2, and fork body 3 is then placed onto the locking block 28 through the locking groove 27. Finally, a wrench is used to tighten the set screw 29 through the mounting hole 13, completing the installation of the handle lock structure.
