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.

[0048] 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.

[0049] First embodiment:

[0050] like Figure 1-9 As shown, in this embodiment, there is provided an idle-rotating push-type safety handle, comprising a rotating handle 1, a base 2, a rotating assembly, a handle elastic member 3, a positioning elastic member 4, a positioning member 5 and a connecting shaft 6;

[0051] The middle end of the connecting shaft 6 is rotatably matched with the base 2;

[0052] The rotating assembly includes an idle sleeve 7 and a positioning sleeve 8. The positioning sleeve 8 is provided with a connecting piece 11 connected to the top end of the connecting shaft 6. The idle sleeve 7 is sleeved on the positioning sleeve 8. The idle sleeve 7 is provided with a first groove 9 and a first protrusion 10.

[0053] The rotating handle 1 is sleeved on the rotating assembly and connected to the idle sleeve 7, and is relatively rotated with the base 2;

[0054] The handle elastic member 3 is arranged between the rotating handle 1 and the positioning sleeve 8 , and the positioning elastic member 4 is arranged between the positioning member 5 and the base 2 .

[0055] The safety handle of this embodiment has multiple states:

[0056] Reference Figure 3 When in the locked state, under the elastic force of the handle elastic member 3, the first groove 9 cooperates with the connecting member 11, at this time, the idling sleeve 7 and the positioning sleeve 8 are a relatively integrated structure, and the first protrusion 10 is separated from the positioning sleeve 8. Under the elastic force of the positioning elastic member 4, the positioning member 5 cooperates with the positioning sleeve 8. At this time, when the user rotates the handle 1, the rotating handle 1 cannot be rotated because of the limiting effect of the positioning member 5 on the positioning sleeve 8, thereby achieving a locking effect;

[0057] When the window is in the closed state and in the idling state, the user rotates the rotary handle 1, and the first groove 9 is separated from the connecting member 11. At this time, the idling sleeve 7 and the positioning sleeve 8 are relatively separated structures, the first protrusion 10 and the positioning sleeve 8 are still separated, and the positioning member 5 is still in the matching state with the positioning sleeve 8. At this time, when the user rotates the rotary handle 1, the connecting shaft 6 cannot be rotated because the positioning member 5 limits the positioning sleeve 8. At the same time, the idling sleeve 7 rotates relative to the positioning sleeve 8, thereby achieving an idling effect;

[0058] Reference Figure 4 When in the linkage state, the user continues to press the rotating handle 1 downward, at this time the first groove 9 is separated from the connecting member 11, and at the same time the first protrusion 10 cooperates with the positioning sleeve 8, and acts to separate the positioning member 5 from the positioning sleeve 8. At this time, the idling sleeve 7 and the positioning sleeve 8 are a relatively integrated structure. At this time, when the user acts to rotate the rotating handle 1, because the positioning member 5 loses its limiting effect on the positioning sleeve 8, the rotating handle 1 can also drive the connecting shaft 6 to rotate while rotating, thereby achieving a linkage effect.

[0059] In this embodiment, specifically, the connecting member 11 is a connecting pin, which passes through the positioning sleeve 8 and the connecting shaft 6, and the end of the connecting pin extending out of the positioning sleeve 8 can be matched with the first groove 9;

[0060] In this embodiment, the number of corresponding first grooves 9 is four, which are arranged on the top end surface of the idler sleeve 7 and are evenly distributed along the radial direction of the idler sleeve 7 .

[0061] Meanwhile, the first protrusion 10 is arranged on the bottom end surface of the idle sleeve 7 , and the positioning sleeve 8 is also provided with a first through hole 12 for the first protrusion 10 or the positioning member 5 to pass through.

[0062] In the above structure, when the first protrusion 10 matches with the first through hole 12 , the first protrusion 10 will act to separate the positioning member 5 from the first through hole 12 , so that the positioning member 5 loses the limiting effect on the positioning sleeve 8 .

[0063] This embodiment further includes a stop sleeve 26, which is sleeved on the connecting shaft 6 and is located between the base 2 and the positioning sleeve 8;

[0064] The specific structure of the anti-retraction sleeve is provided with a second protrusion 13 and a through groove 14. The position of the through groove 14 corresponds to the position of the positioning member 5. The first protrusion 10 is provided with a clamping groove 15.

[0065] After the safety handle is in the linkage state, it can be further in the open position. The specific structural principle is as follows:

[0066] When the first groove 9 is separated from the connecting member 11, the first protrusion 10 is matched with the positioning sleeve 8. The size of the first through hole 12 of this embodiment is larger than the cross section of the first protrusion 10. At this time, the first protrusion 10 passes through the through groove 14 to separate the positioning member 5 from the positioning sleeve 8, and then the rotating handle 1 is rotated to adjust the position of the first protrusion 10 in the first through hole 12, so that the slot 15 of the first protrusion 10 is matched with the second protrusion 13. At this time, the stop sleeve will limit the position of the first protrusion 10 in the first through hole 12, thereby preventing the idle sleeve 7 from moving due to the elastic force of the handle elastic member 3, so as to ensure that the safety handle is always in the open position. When the above state needs to be released, there is no need to press the rotating handle 1. It is only necessary to rotate the rotating handle 1 to adjust the position of the first protrusion 10 in the first through hole 12, so that the slot 15 of the first protrusion 10 is separated from the second protrusion 13. Under the elastic force of the handle elastic member 3, the first protrusion 10 is separated from the positioning sleeve 8, thereby returning to the idle state.

[0067] As for the specific structure of the anti-recession sleeve, the second protrusion 13 is an arc-shaped structure, and there are two of them which are symmetrically arranged on the top end face of the anti-recession sleeve. A through groove 14 is formed between the two second protrusions 13, and the bottom end face of the anti-recession sleeve is provided with a limiting protrusion 27 which cooperates with the base 2. The limiting protrusion can prevent the anti-recession sleeve from rotating, thereby ensuring that the position of the through groove 14 always corresponds to the position of the first through hole 12.

[0068] In this embodiment, refer to Figure 5The structure of the base 2 is specifically as follows: an annular groove 16 is provided on the top end surface of the base 2, and the bottom end of the rotating handle 1 matches the annular groove 16. The top end surface of the base 2 is also provided with a second through hole 17, a second groove 18, a third groove 19 and a fourth groove 20, wherein the second through hole 17 is coaxially arranged with the second groove 18, and the third groove 19 and the fourth groove 20 are arranged around the second through hole 17;

[0069] The second through hole 17 is for the connecting shaft 6 to pass through, the second groove 18 is used to place the anti-retraction sleeve, and the third groove 19 is used to place the positioning elastic member 4 and the positioning member 5.

[0070] At the same time, a marble component 21 and a marble spring component 22 are provided in the fourth groove 20. One end of the marble component 21 is in contact with the positioning sleeve 8. The marble component 21 and the marble spring component 22 act on the positioning sleeve 8 through elastic force, and the elastic force of the handle elastic component 3 is combined to ensure the overall structural stability.

[0071] In this embodiment, the connection structure between the rotating handle 1 and the positioning sleeve 8 is as follows: a locking screw 28 is provided on the rotating handle 1 , and one end of the locking screw is connected to the idle sleeve 7 .

[0072] In this embodiment, the handle elastic member 3 and the positioning elastic member 4 are both spring members.

[0073] The utility model also provides a panel assembly, including a frame 23, on which are provided a transmission assembly 24, a transmission bar 25 and the above-mentioned idling push-type safety handle, the connecting shaft 6 of the idling push-type safety handle is connected to the transmission assembly 24, and the transmission bar 25 is connected to the transmission assembly 24.

[0074] The effects of idling and linkage unlocking can be achieved by the transmission assembly 24 and the transmission bar 25 in combination with various states of the idling push-type safety handle.

[0075] The panel assembly of the utility model, when the window is closed, refers to Figure 8 , 9 This is an idling diagram. For the state diagram of opening the window, pressing and rotating the handle and unlocking, refer to Figure 6 , refer to the schematic diagram of the window closing to unlock the rotary handle and restore the handle to the safety or locked state Figure 7 .

[0076] Second embodiment:

[0077] Reference Figure 10-12 The free-wheeling push-type safety handle provided in this embodiment includes a rotating handle 1, a base 2, a handle elastic member 3, a connecting shaft 6, a handle shaft kit 29, a fixing position kit 30, a decorative ring 31, a pressing column member 32, a tightening screw member 33, a square shaft kit 34 and a lower cover 35, and the base 2 is a square structure;

[0078] Among them, the handle shaft kit 29, the fixed position kit 30, the pressing column 32, and the square shaft kit 34 constitute the structure of the rotating assembly. Specifically, the top end of the connecting shaft 6 is tightly matched with the square shaft kit 34, the square shaft kit 34 is fixed in the base 2 through the lower cover 35, the pressing column 32 is sleeved on the square shaft kit 34, a third protrusion 36 is provided on the square shaft kit 34, a fifth groove 37 is provided on the pressing column 32, a first guide portion 38 for the pressing column 32 to pass through is provided on the base, the decorative ring 31 is fixed to the base 2 and sleeved on the first guide portion 38, and the handle elastic member 3 is sleeved on the first guide portion 38. A guide portion 38, the bottom end of the handle elastic member 3 is in the decorative ring 31, the top end of the handle elastic member 3 is in contact with the bottom end of the fixed position set 30, the handle shaft set 29 is arranged at the top end of the fixed position set 30, the handle shaft set 29 is provided with a second guide portion 39 that is slidably matched with the pressing column 32, the tightening screw 33 is connected to the second guide portion 39 and can limit the second guide portion 39 from moving out of the pressing column 32, the rotating handle 1 is closely matched with the handle shaft set 29, a sixth groove 40 is provided at the first guide portion 38, and a fourth protrusion 41 is also provided on the pressing column 32;

[0079] The principles of various states of this embodiment are as follows: under the elastic force of the handle elastic member 3, when the fourth protrusion 41 of the pressing column 32 matches the sixth groove 40 at the first guide portion 38, the pressing column 32 cannot rotate relative to the base 2 when not pressed. At the same time, because the pressing column 32 is not pressed, the third protrusion 36 of the square shaft sleeve 34 does not match the fifth groove 37 of the pressing column 32, and the pressing column 32 cannot drive the square shaft sleeve to rotate. When the rotating handle is pressed, the pressing column 32 moves toward the base, and the handle shaft sleeve 29 acts on the fixed position sleeve 30 to move toward the base. When the fixed position sleeve 30 supports the base, the fourth protrusion 41 of the pressing column 32 separates from the sixth groove 40 at the first guide portion 38, and the handle shaft sleeve 29, the fixed position sleeve 30 and the base are completely squeezed together. In this state, the rotation of the rotating handle can drive the rotation of the pressing column 32. As the pressing column 32 moves toward the base, when the fixing assembly 30 presses against the base, the fifth groove 37 of the pressing column 32 is combined with the third protrusion 36 of the square shaft sleeve, and the connecting shaft can be rotated by turning the rotating handle, so that the transmission assembly can be operated by turning the rotating handle when the rotating handle is pressed to the bottom.

[0080] Third embodiment:

[0081] like Figure 13-14As shown, the difference between this embodiment and the first embodiment is that the connecting piece is eliminated, and a connecting shaft connecting screw 42 and a positioning ring 43 are added. The connecting shaft connecting screw 42 passes through the positioning ring 43 and the positioning sleeve 8 and is fixed on the connecting shaft 6. The end surfaces of the idle sleeve 7 and the positioning ring directly match each other and adopt a matching structure in which the concave position and the convex position match each other. When the convex position matches the concave position, the idle sleeve can be positioned at a specified angle, and the handle can be limited between the locked and opened positions. It is easier to find the locked position when opening the window sash, making it more convenient to open the window.

[0082] Fourth embodiment:

[0083] like Fig.15 As shown, the difference between this embodiment and the third embodiment is that a fifth protrusion 44 is provided on the positioning sleeve 8, and a seventh groove 45 is provided on the idling sleeve 7. When the first protrusion 10 cooperates with the first through hole 12, the fifth protrusion 44 cooperates with the seventh groove 45. When the first protrusion 10 is separated from the first through hole 12, during the rotation of the idling sleeve 7 relative to the positioning sleeve 8, the fifth protrusion 44 of the positioning sleeve 8 will abut against the first protrusion 10, thereby limiting the rotation angle of the idling sleeve 7 relative to the positioning sleeve 8. Through the position structure of the fifth protrusion, the rotating handle 1 of this embodiment is limited to idle rotation within a specified angle.

[0084] To sum up, the structural design of this embodiment is reasonable. By adding an idling function, the handle can be operated, but the window cannot be opened, and the steps of turning the handle to open the window are appropriately increased. However, most children lack patience. They can operate the handle normally using the conventional window opening method, but if they cannot open the window, they will give up. This ensures that the window is closed relatively safely. When the window needs to be opened, it can be opened in the correct way.

[0085] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
