[0050] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0052] Example 1

[0053] See also Figure 1-Figure 4 This embodiment discloses a double-hook lock body, comprising a base body 2, a top rod 1, an elastic element 4 and two locking pieces 3. The base body 2 comprises a base 201 and a base cover 202, the base 201 and the base cover 202 are detachably connected, the base 201 is provided with an inner cavity, the locking piece 3, the elastic element 4 and the first end 101 of the top rod 1 are all arranged in the inner cavity of the base 201. The base 201 is provided with two locking holes 2011 that cooperate with the lock hook 5.

[0054] The push rod 1 can be slidably arranged in the base 201; the first end 101 of the push rod 1 is located in the base 201, and the second end 102 of the push rod 1 passes through the base 201 and corresponds to the handle driving end; the elastic element 4 is arranged between the push rod 1 and the base 201, and the elastic force of the elastic element 4 always causes the push rod 1 to have a tendency to move toward the side of passing through the base 201; recesses 1031 are respectively provided on both sides of the push rod 1. The two locking pieces 3 can be rotatably arranged in the base 201 and are respectively located on both sides of the push rod 1; the second ends 302 of the two locking pieces 3 are respectively embedded in the two recesses 1031, and the first ends 301 of the two locking pieces 3 under normal conditions overlap with parts of the two locking holes 2011 to lock the lock hook 5.

[0055] The double hook lock body of this embodiment is generally used in conjunction with the handle on the door and window profile. The handle can be a push-type handle or a handle screw-type handle, which is an operating component provided to the user to operate to control the unlocking or locking of the door and window. The handle driving end, that is, after the user's operation and control, drives the handle driving end to move, thereby acting on the second end 102 of the top rod 1 of the double hook lock body of this embodiment, prompting the top rod 1 to move and drive the lock plate 3 to rotate, and finally completing the release of the lock body to the lock hook 5 to complete the unlocking. For example, after the user rotates or presses the handle, the handle driving end prompts the top rod 1 to move to one side of the first end 101 (towards the base 201), driving the two lock plates 3 to rotate so that the second end 302 of the lock plate 3 no longer blocks the lock hook 5, and the door and window are unlocked.

[0056] See also Figure 1-Figure 2 Furthermore, in this embodiment, both sides of the push rod 1 are provided with raised portions 103, the two raised portions 103 are symmetrically arranged and located in the base 201, and the two recessed positions 1031 are respectively arranged on the two raised portions 103; the base 201 is provided with an avoidance hole 2014, and the push rod 1 is inserted into the avoidance hole 2014; the raised portion 103 is larger than the avoidance hole 2014.

[0057] As a preferred solution, the concave position 1031 is set as an arc structure in this embodiment, which can be seen in Figure 1 . In this embodiment, by setting the protrusion 103 on the top rod 1, on the one hand, it is convenient to set and process the concave position 1031, so that it can cooperate with the end (second end 302) of the locking plate 3, and drive the locking plate 3 to rotate when the top rod 1 is telescopic and sliding, and finally achieve the unlocking or locking of the lock hook 5; on the other hand, the setting of the protrusion 103 is larger than the avoidance hole 2014 on the base 201. Therefore, when the top rod 1 is reset under the elastic force of the elastic element 4, the protrusion 103 plays a positioning and limiting role, accurately driving the two locking plates 3 to reset and rotate to the specified angle to complete the locking of the lock hook 5, and limiting the top rod 1 from escaping from the base 201 under the elastic force. It can be seen that the design of the protrusion 103 in this embodiment is simple in structure, ingenious in design, good in effect, and multi-functional.

[0058] See also Figure 1, further, the base 201 is provided with a limiting groove 2012, the elastic element 4 is arranged in the limiting groove 2012, the first end 101 of the push rod 1 is aligned with the limiting groove 2012, and the two ends of the elastic element 4 act on the base 201 and the first end of the push rod 1. Specifically, the limiting groove 2012 and the push rod 1 of this embodiment can be understood as the same axis, and in order to improve the telescopic sliding stability of the push rod 1, the first end 101 of the push rod 1 is located in the limiting groove 2012 under normal conditions, and the elastic element 4 can be a spring, which can be sleeved on the protrusion of the first end 101 of the push rod 1. In addition, two opposing baffles are arranged on the base 201 of this embodiment, and the limiting groove 2012 is formed between the two baffles. The elastic element 4 is arranged in this way, the structural requirements of the base 201 are low, the structure is simple and easy to manufacture, and the effect is good. The elastic element 4 can stably and reliably produce elastic action on the push rod 1, so as to achieve reset and complete the automatic locking effect of the lock hook 5.

[0059] See also Figure 1-Figure 2 , further, the locking piece 3 is bent and includes a first section and a second section; the inner angle of the locking piece 3 faces the side of the top rod 1, and the bent corner of the locking piece 3 is rotatably connected to the base 201; the non-connected end of the first section is the first end 301 of the locking piece 3, and the non-connected end of the second section is the second end 302. Figure 1 In this embodiment, the locking piece 3 is bent and the inner angle of the bend is toward the top rod 1, so that the two locking pieces 3 are symmetrical and the structure is more compact and reliable, which can reduce the volume of the lock body and save installation space. In addition, in order to facilitate the rotation connection between the locking piece 3 and the base 201, two columns 2013 are provided on the base 201 in this embodiment, and through holes are provided at the bent corners of the locking piece 3 to cooperate with the columns 2013 so as to realize the rotation of the locking piece 3.

[0060] Moreover, in a normal state, the first end 301 of the locking piece 3 overlaps with the end of the locking hole 2011 away from the push rod 1; when the push rod 1 overcomes the elastic force of the elastic element 4 and moves into the lock body, the first end 301 of the locking piece 3 rotates to the side away from the push rod 1 to leave the locking hole 2011. In this way, the first end of the locking piece 3 is easy to cooperate with the lock hook 5.

[0061] Example 2

[0062] See also Figure 1-Figure 10 This embodiment discloses a double hook lock assembly, including the double hook lock body in embodiment 1, as well as a lock hook 5 and a handle. Figure 2-Figure 4As shown, the lock hook 5 is provided with two hook portions 501, and both of the two hook portions 501 are provided with hook surfaces 503. In the locked state, the two hook portions 501 respectively pass through the two lock holes 2011 of the double-hook lock body and then extend into the base 201, and the first ends of the two locking plates 3 are respectively blocked by the two hook surfaces 503 to achieve a locking effect. The handle includes an operating end and a driving end, and the driving end corresponds to the top rod 1.

[0063] The two hooks 501 in this embodiment are both provided with an introduction slope 502. Figure 2 As shown, during the process of locking doors and windows, when the door or window sash with the lock hook 5 is closed, the guide slope 502 of the lock hook 5 penetrates into the lock hole 2011, and during the penetration process, the guide slope 502 is used to push the lock plate 3, so that the lock plate 3 rotates to avoid, and when the guide slope 502 passes through the lock plate 3, the lock plate 3 is reset under the elastic force of the elastic element 4, and the hook surface 503 of the hook portion 501 is blocked, completing the automatic locking of the lock hook 5 and the locking of the door and window. The setting of the guide slope 502 also facilitates the hook portion 501 of the lock hook 5 to pass through the lock plate 3 more smoothly and conveniently.

[0064] Furthermore, the lock hook 5 of this embodiment is provided with a hole, which can be matched with a top screw, so as to be conveniently and quickly installed on the profile. Moreover, the lock hook 5 of this embodiment is also provided with an installation part to improve the matching degree with the profile and improve the reliability after installation.

[0065] In this embodiment, the handle is a push-type handle, and the operating end is a cover. When unlocking, the driving end drives the push rod 1 to move into the base 201 by pressing the cover, thereby driving the locking plate 3 to rotate to complete the unlocking.

[0066] See also Figure 5-Figure 10 Specifically, the specific structure of the push-type handle is as follows: it includes a shell 2a, a cover 1a and a telescopic slider 3a.

[0067] The shell 2a is installed on the profile, and the shell 2a is provided with a sliding cavity 2016a with an opening facing outward. The surface cover 1a can be slidably arranged in the sliding cavity 2016a along a direction perpendicular to the bottom surface of the shell 2a; a first elastic element 6a that can generate an outward thrust on the surface cover 1a is provided between the surface cover 1a and the shell 2a, and the surface cover 1a and / or the shell 2a are provided with an anti-slip structure for preventing the surface cover 1a from slipping out.

[0068] The telescopic slider 3a can be slidably arranged in the shell 2a, and the sliding direction of the telescopic slider 3a is perpendicular to the sliding direction of the surface cover 1a. The shell 2a is provided with a through hole 2013a to allow the telescopic slider 3a to slide out or retract, and the telescopic slider 3a is provided with an inclined guide surface 302a; the surface cover 1a is provided with a rolling member 7a, and the rolling member 7a corresponds to the guide surface 302a; when the surface cover 1a slides inward, the rolling member 7a acts on the guide surface 302a to prompt the telescopic slider 3a to slide outward.

[0069] In this embodiment, the telescopic slider 3a corresponds to the second end 102 of the top rod 1 in the embodiment 1. When the telescopic slider 3a is extended, it can push the top rod 1 to move into the base 201, thereby triggering the unlocking of the lock body. That is, the telescopic slider 3a constitutes the driving end of the handle, and the cover 1a constitutes the operating end of the handle.

[0070] The rolling member 7a of this embodiment is a rolling sleeve. The surface cover 1a is provided with a cylinder 101a, and the rolling sleeve can be rolled on the cylinder 101a. The rolling sleeve has a certain contact surface with the guide surface 302a of the telescopic slider 3a, and there is rolling friction between the rolling sleeve and the guide surface 302a, so the smoothness and feel of pressing the surface cover 1a to make the telescopic slider 3a slide out can be further improved, and the stability is better.

[0071] As another embodiment, the rolling element 7a of this embodiment can also be a roller, a ball or other structure to cooperate with the guide surface 302a of the telescopic slider 3a, which can also achieve the effect of rolling friction between the two and improve the smoothness and feel of the handle. At the same time, the number of rolling elements 7a can be flexibly set according to actual conditions. For example, the rolling sleeve of this embodiment adopts one, but of course two or more can also be adopted.

[0072] Furthermore, the telescopic slider 3a of this embodiment is provided with a guide groove 301a, one side of the guide groove 301a is open, and both opposite sides of the guide groove 301a are guide surfaces 302a. One end of the cylinder 101a on the cover 1a is connected to the cover 1a, and the other end is suspended and extended. The rolling sleeve is sleeved on the cylinder 101a and is embedded in the guide groove 301a through the open surface of the guide groove 301a. The inclination direction of the guide groove 301a is as follows: Figure 7As shown. By providing the guide groove 301a on the telescopic slider 3a, the rolling element 7a can cooperate with it more compactly and reliably, and can drive the telescopic slider 3a to slide simultaneously when the cover 1a is pressed or released to reset. Specifically, when the cover 1a is pressed, the force of the rolling element 7a is mainly applied to the guide surface 302a close to the outside of the guide groove 301a, thereby pushing the telescopic slider 3a to slide outward; when the cover 1a is reset by the elastic force of the first elastic element 6a, the force of the rolling element 7a is mainly applied to the guide surface 302a on the inside of the guide groove 301a, thereby driving the telescopic slider 3a to slide inward and retract.

[0073] As another embodiment, a guide surface 302a can also be directly set on the telescopic slider 3a. When the face cover 1a is under pressure, the rolling member 7a applies pressure to push the telescopic slider 3a to extend; when the face cover 1a is reset, the rolling member 7a does not act on the telescopic slider 3a, and the retraction and reset of the telescopic slider 3a can be driven by the action end of the door and window lock body. For example, the door and window lock body is provided with a push rod. When the push rod is reset by the elastic force of the elastic member inside the lock body, a thrust is generated on the telescopic slider 3a, thereby causing the telescopic slider 3a to retract.

[0074] The housing 2a of this embodiment includes an outer shell 201a and a bottom cover 202a, and the outer shell 201a and the bottom cover 202a are detachably connected. Specifically, the outer shell 201a and the bottom cover 202a in this embodiment can be assembled by rivets or buckles. The bottom cover 202a is set as a separate component, so that a special structure is set on the bottom cover 202a to achieve cooperation with the surface cover 1a, the telescopic slider 3a, etc., and the outer shell 201a can simplify the structure and facilitate manufacturing.

[0075] Furthermore, the bottom cover 202a is provided with a first slide groove 2021a, and first guide convex rails 2022a are respectively provided on both sides of the first slide groove 2021a; first guide grooves 303a are respectively provided on both sides of the telescopic slider 3a, and the first guide grooves 303a match the first guide convex rails 2022a, and the telescopic slider 3a can be slidably arranged in the first slide grooves 2021a; the perforation 2013a is arranged on the side of the housing 201a, and is used to avoid the telescopic slider 3a. In this way, through the matching of the first guide convex rails 2022a and the first guide grooves 303a, the assembly and guidance of the telescopic slider 3a and the bottom cover 202a are realized, and good stability is achieved. In addition, a groove structure can also be provided on the bottom cover 202a, and a convex rail structure can be provided on the telescopic slider 3a, and the cooperation of the two can also realize sliding guidance.

[0076] Furthermore, the opening edge of the shell 201a extends outward to form a retaining edge 2012a, and a protruding positioning block 2011a is provided on one side of the shell 201a, and a positioning gap for matching with the profile is formed between the positioning block 2011a and the retaining edge 2012a. A locking assembly 4a is provided on the side opposite to the locking block 2011a, and the locking assembly 4a includes a locking block 402a, an adjusting member 401a and a second elastic element 403a; the locking block 402a can be slidably extended or retracted and is arranged on the bottom cover 202a, and an inclined surface 4024a is provided on the locking block 402a, the adjusting member 401a is threadedly connected to the bottom cover 202a and abuts against the inclined surface 4024a, and the second elastic element 403a acts on the bottom cover 202a and the locking block 402a, and the elastic force of the second elastic element 403a produces a retracting force on the locking block 402a; an avoidance hole 2017a is provided on the side of the shell 201a corresponding to the locking block 402a; the locking block 402a is controlled to extend or retract into the shell 201a by screwing the adjusting member 401a in or out, thereby realizing the locking or loosening of the profile.

[0077] Furthermore, two opposing protrusions 204a are provided on the bottom cover 202a, and the locking block 402a is located between the two protrusions 204a; the second elastic element 403a is a torsion spring, and a protrusion 4022a is provided on the locking block 402a, and the torsion spring is sleeved on the protrusion 4022a, and the two ends of the torsion spring abut against the two protrusions 204a. Furthermore, a notch 2042a is provided on the protrusion 204a of this embodiment, and the two ends of the torsion spring extend into the notch 2042a to improve the stability of the torsion spring.

[0078] In addition, one of the protrusions 204a is provided with a threaded hole 2041a for cooperating with the adjusting member 401a, and a corresponding hole 2015a is also provided on the side of the housing 201a, so that the adjusting member 401a can be screwed with a tool outside the housing 201a to achieve locking and installation or loosening and disassembly of the handle. Further, a second guide convex rail 2023a is provided between the two protrusions 204a of this embodiment, and a second guide groove 4023a is correspondingly provided on the locking block 402a. The structure can be seen in Figure 7 .

[0079] In order to better tighten and fix the profile through the locking block 402a, the locking block 402a of this embodiment faces the side of the outer shell 201a rib 2012a as a locking surface 4021a, and the locking surface 4021a is inclined, so that the locking block 402a can gradually tighten the profile during the extension process, and cooperate with the rib 2012a of the outer shell 201a to form a clamping effect. Specifically, when installing the push-type handle of this embodiment, the entire handle is placed in the cavity of the profile, and the positioning block 2011a is embedded in the inner side of the edge of the profile, and the edge of the profile is clamped together with the rib 2012a of the outer shell 201a to achieve a pre-fixing effect. Subsequently, by screwing the adjusting member 401a, the locking block 402a is gradually extended out of the housing 201a, and the locking surface 4021a on the locking member is pressed against the inner side of the profile, and similarly cooperates with the retaining edge 2012a of the housing 201a to clamp the profile, and the installation and fixation of the handle can be completed. When disassembling, the adjusting member 401a is screwed to allow the locking block 402a to automatically retract and return to its original position under the action of the second elastic element 403a, and the handle can return to a relaxed state, and the handle can be taken out at this time. The locking assembly 4a of this embodiment can firmly lock the handle on the profile, especially compared with the traditional buckle method, the locking block 402a has a stronger pressing force on the profile, making the handle more stable and reliable.

[0080] The limiting structure of this embodiment can adopt various types of embodiments as long as it can prevent the cover 1a from falling out of the shell 201a. For example, the opening edge of the shell 2a of this embodiment extends inward to form a clamping edge 2014a, and a protruding clamping block 102a is provided on each side of the cover 1a; the clamping block 102a and the clamping edge 2014a constitute a limiting structure.

[0081] The side of the face cover 1a of the present embodiment is provided with a muffler block 5a. Specifically, the muffler block 5a can be provided on each side and each corner position of the face cover 1a or the muffler block 5a can be selectively provided. The provision of the muffler block 5a can, on the one hand, eliminate the noise when the face cover 1a slides, and on the other hand, can further enhance the feel and smoothness of pressing the face cover 1a. In order to facilitate the installation of the muffler block 5a and the face cover 1a, a card slot can be provided at the corner of the face cover 1a, or a slot 103a can be provided on the muffler block 5a, so that the muffler block 5a and the face cover 1a can be embedded and fixed.

[0082] In this embodiment, the first elastic element 6a is a spring, and two of them are provided. Of course, the number can be flexibly set according to the actual situation. To facilitate the assembly of the spring, a positioning member is provided on the bottom cover 202a, and the positioning member includes a positioning column 203a and a positioning ring 205a.
