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.

[0043] 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.

[0044] Example 1

[0045] See also Figure 1-Figure 6 This embodiment discloses a push-type handle, including a housing 2, a cover 1 and a telescopic slider 3.

[0046] The shell 2 is installed on the profile, and the shell 2 is provided with a sliding cavity 2016 with an opening facing outward. The face cover 1 can be slidably arranged in the sliding cavity 2016 along a direction perpendicular to the bottom surface of the shell 2; a first elastic element 6 that can generate an outward thrust on the face cover 1 is provided between the face cover 1 and the shell 2, and the face cover 1 and / or the shell 2 are provided with an anti-slip structure for preventing the face cover 1 from slipping out.

[0047] The telescopic slider 3 can be slidably arranged in the shell 2, and the sliding direction of the telescopic slider 3 is perpendicular to the sliding direction of the face cover 1. The shell 2 is provided with a through hole 2013 to allow the telescopic slider 3 to slide out or retract, and a guide surface 302 is obliquely arranged on the telescopic slider 3; the face cover 1 is provided with a rolling member 7, and the rolling member 7 corresponds to the guide surface 302; when the face cover 1 slides inward, the rolling member 7 acts on the guide surface 302 to prompt the telescopic slider 3 to slide outward.

[0048] In this embodiment, the telescopic slider 3 corresponds to the lock body driving end of the door and window lock, and when the telescopic slider 3 is extended, it can push the lock body driving end, thereby triggering the unlocking of the lock body. For example, the lock body of the door and window lock can be a double hook lock, and the telescopic slider 3 corresponds to the push rod of the double hook lock.

[0049] The rolling member 7 of this embodiment is a rolling sleeve. The surface cover 1 is provided with a cylinder 101, and the rolling sleeve can be rolled on the cylinder 101. The rolling sleeve has a certain contact surface with the guide surface 302 of the telescopic slider 3, and there is rolling friction between the rolling sleeve and the guide surface 302, so the smoothness and feel of pressing the surface cover 1 to make the telescopic slider 3 slide out can be further improved, and the stability is better.

[0050] As another embodiment, the rolling element 7 of this embodiment can also adopt a structure such as a roller, a ball, etc. to cooperate with the guide surface 302 of the telescopic slider 3, which can also achieve the effect of rolling friction between the two, and can also improve the smoothness and feel of the handle. At the same time, the number of rolling elements 7 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.

[0051] Furthermore, the telescopic slider 3 of this embodiment is provided with a guide groove 301, one side of the guide groove 301 is open, and both opposite sides of the guide groove 301 are guide surfaces 302. One end of the cylinder 101 on the cover 1 is connected to the cover 1, and the other end is suspended and extended. The rolling sleeve is sleeved on the cylinder 101 and is embedded in the guide groove 301 through the open surface of the guide groove 301. The inclination direction of the guide groove 301 is as shown in FIG. Figure 3As shown. By providing the guide groove 301 on the telescopic slider 3, the rolling element 7 can cooperate with it more compactly and reliably, and can drive the telescopic slider 3 to slide simultaneously when the cover 1 is pressed or released to reset. Specifically, when the cover 1 is pressed, the force of the rolling element 7 is mainly applied to the guide surface 302 close to the outside of the guide groove 301, thereby pushing the telescopic slider 3 to slide outward; when the cover 1 is reset by the elastic force of the first elastic element 6, the force of the rolling element 7 is mainly applied to the guide surface 302 on the inside of the guide groove 301, thereby driving the telescopic slider 3 to slide inward and retract.

[0052] As another embodiment, a guide surface 302 can also be directly set on the telescopic slider 3. When the face cover 1 is under pressure, the rolling member 7 applies pressure to push the telescopic slider 3 to extend; when the face cover 1 is reset, the rolling member 7 does not act on the telescopic slider 3, and the retraction and reset of the telescopic slider 3 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 3, thereby causing the telescopic slider 3 to retract.

[0053] The housing 2 of this embodiment includes a shell 201 and a bottom cover 202, and the shell 201 and the bottom cover 202 are detachably connected. Specifically, the shell 201 and the bottom cover 202 in this embodiment can be assembled by rivets or buckles. The bottom cover 202 is set as a separate component, so that a special structure can be set on the bottom cover 202 to achieve cooperation with the surface cover 1, the telescopic slider 3, etc., while the shell 201 can simplify the structure and facilitate manufacturing. The sliding cavity 2016 of this embodiment is set in the shell 201.

[0054] Furthermore, the bottom cover 202 is provided with a first slide groove 2021, and first guide convex rails 2022 are respectively provided on both sides of the first slide groove 2021; first guide grooves 303 are respectively provided on both sides of the telescopic slider 3, and the first guide grooves 303 match the first guide convex rails 2022, and the telescopic slider 3 can be slidably arranged in the first slide grooves 2021; the perforation 2013 is arranged on the side of the housing 201, and is used to avoid the telescopic slider 3. In this way, through the matching of the first guide convex rails 2022 and the first guide grooves 303, the assembly and guidance of the telescopic slider 3 and the bottom cover 202 are realized, and good stability is achieved. In addition, a groove structure can also be provided on the bottom cover 202, and a convex rail structure can be provided on the telescopic slider 3, and the cooperation of the two can also realize sliding guidance.

[0055] Furthermore, the opening edge of the housing 201 extends outward to form a retaining edge 2012 , and a protruding positioning block 2011 is provided on one side of the housing 201 , and a positioning gap for matching with the profile is formed between the positioning block 2011 and the retaining edge 2012 . A locking assembly 4 is provided on the side opposite to the locking block 2011, and the locking assembly 4 includes a locking block 402, an adjusting member 401 and a second elastic element 403; the locking block 402 can be slidably extended or retracted and is arranged on the bottom cover 202, and an inclined surface 4024 is provided on the locking block 402, the adjusting member 401 is threadedly connected to the bottom cover 202 and abuts against the inclined surface 4024, and the second elastic element 403 acts on the bottom cover 202 and the locking block 402, and the elastic force of the second elastic element 403 produces a retracting force on the locking block 402; an avoidance hole 2017 is provided on the side of the shell 201 corresponding to the locking block 402; the locking block 402 is controlled to extend or retract into the shell 201 by screwing the adjusting member 401 in or out, thereby realizing the locking or loosening of the profile.

[0056] Furthermore, two opposing protrusions 204 are provided on the bottom cover 202, and the locking block 402 is located between the two protrusions 204; the second elastic element 403 is a torsion spring, and a protrusion 4022 is provided on the locking block 402, and the torsion spring is sleeved on the protrusion 4022, and the two ends of the torsion spring abut against the two protrusions 204. Furthermore, a notch 2042 is provided on the protrusion 204 of this embodiment, and the two ends of the torsion spring extend into the notch 2042 to improve the stability of the torsion spring.

[0057] In addition, one of the protrusions 204 is provided with a threaded hole 2041 for cooperating with the adjusting member 401, and a corresponding hole 2015 is provided on the side of the housing 201, so that the adjusting member 401 can be screwed with a tool outside the housing 201 to achieve locking and installation or loosening and removal of the handle. Further, a second guide convex rail 2023 is provided between the two protrusions 204 of this embodiment, and a second guide groove 4023 is provided on the locking block 402 accordingly. The structure can be seen in Figure 3 .

[0058] In order to better tighten and fix the profile through the locking block 402, the locking block 402 of this embodiment is provided with a locking surface 4021 on the side facing the flange 2012 of the housing 201. The locking surface 4021 is tilted so that the locking block 402 can gradually tighten the profile during the extension process and cooperate with the flange 2012 of the housing 201 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 2011 is embedded in the inner side of the edge of the profile, and the edge of the profile is clamped together with the flange 2012 of the housing 201 to achieve a pre-fixing effect. Subsequently, by screwing the adjusting member 401, the locking block 402 is gradually extended out of the housing 201, and the locking surface 4021 on the locking member is pressed against the inner side of the profile, and the profile is clamped in cooperation with the flange 2012 of the housing 201, so that the installation and fixation of the handle can be completed. When disassembling, the adjusting member 401 is screwed to allow the locking block 402 to automatically retract and return to its original position under the action of the second elastic element 403, and the handle can be restored to a relaxed state, at which time the handle can be taken out. The locking assembly 4 of this embodiment can firmly lock the handle on the profile, and compared with the traditional buckle method, the locking block 402 has a stronger pressing force on the profile, making the handle more stable and reliable.

[0059] The anti-drop structure of this embodiment can adopt various types of embodiments as long as it can prevent the cover 1 from falling out of the housing 201.
