Description

Technical Field

[0001] The invention relates to the technical field of door and window accessories, in particular to a handle lock for doors and windows. Background Art

[0002] The handle lock is one of the main accessories for doors and windows. Generally, the handle lock for doors and windows mainly includes a base fixed on the door and window frame, a rotating member rotatably assembled in the base, a handle fixed to the rotating member, and a transmission shaft fixedly inserted in the rotating member, and one end of the transmission shaft extending from the rotating member is connected to the transmission mechanism. When the user holds and rotates the handle of the handle lock, the handle drives the rotating member and the transmission shaft to rotate together, and the transmission shaft drives the transmission mechanism to operate, thereby performing the opening and closing operations of the doors and windows.

[0003] At present, the fixing of the rotating part and the handle is fixed by screws, and the fixing of the rotating part and the transmission shaft is fixed by tight fit. For example: the handle lock disclosed in the Chinese utility model patent application number 201520817754.6; another example: the handle disclosed in the Chinese utility model patent application number 201821579262.8. However, the above existing structures have the following defects:

[0004] 1. There may be a gap between the rotating part and the handle, which causes the two to be loose and the handle to become loose easily.

[0005] 2. There is a gap between the transmission shaft and the hole wall of the rotating part. After long-term use, the transmission shaft is easy to loosen, which affects the accuracy of torque transmission and makes it impossible to open or close the doors and windows smoothly. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a handle lock for doors and windows, which increases the reliability of the fixed connection between the rotating member and the handle and prevents the handle from loosening.

[0007] To achieve the above-mentioned purpose, the present invention provides a handle lock for doors and windows, comprising a base, a rotating member rotatably assembled in the base, a handle distributed on one side of the base, and a fastener fixing the rotating member and the handle, wherein the rotating member has a connecting shaft section extending from the base, the handle is provided with an assembly hole for accommodating the connecting shaft section, the connecting shaft section is provided with a first fixing hole matched with the fastener, the handle is provided with a second fixing hole matched with the fastener, the connecting shaft section is provided with a groove body, the groove body penetrates the connecting shaft section along the wall thickness direction of the connecting shaft section, one end of the groove body extends to the first fixing hole and is connected to the first fixing hole; when the fastener is installed in the first fixing hole and the second fixing hole to fix the connecting shaft section and the handle, the groove body allows the connecting shaft section to deform toward the handle.

[0008] The present application forms a groove body on the connecting shaft section of the rotating part by slotting the connecting shaft section. When the fastener is used to fix the connecting shaft section and the handle, the fastener will squeeze the connecting shaft section in the direction close to the handle, causing the connecting shaft section to deform in the direction close to the handle, thereby eliminating any gap that may exist between the connecting shaft section and the handle, and making the outer peripheral surface of the connecting shaft section contact and cooperate with the wall surface of the assembly hole, thereby greatly improving the firmness of the fixed connection between the rotating part and the handle, avoiding loosening of the handle, and ensuring the accuracy and reliability of the handle driving the rotating part to rotate synchronously.

[0009] In the above technical solution, the structure of the groove body on the connecting shaft section is preferably: the connecting shaft section includes a barrel portion extending straightly along the axial direction of the rotating member, and an end plate portion provided at one end of the barrel portion close to the second fixing hole, the first fixing hole is provided in the end plate portion, a part of the groove body is provided on the barrel portion and extends straightly along the axial direction of the barrel portion, and the remaining part of the groove body is provided on the end plate portion and extends straightly along the radial direction of the first fixing hole. In this way, the processing of the groove body is convenient, and the structural strength of the rotating member itself can be ensured, thereby improving the reliability of the fixed connection between the rotating member and the handle.

[0010] The preferred embodiment of the above technical solution is as follows: the fastener is a countersunk screw, the countersunk screw includes a connected screw head and a screw shank, the first fixing hole includes a connected tapered hole section and a straight hole section, the screw head is accommodated in the tapered hole section, and the two are in tapered contact, the straight hole section is a through hole or a threaded hole matched with the screw shank, and the second fixing hole is a threaded hole matched with the screw shank. In the process of screwing the countersunk screw into the first fixing hole and the second fixing hole, the screw head squeezes the hole wall of the tapered hole section, driving a section of the connecting shaft section close to the second fixing hole to deform outward, so that the outer peripheral surface of the connecting shaft section can be closely attached to the hole wall of the assembly hole in the handle, thus eliminating the gap between the connecting shaft section and the hole wall of the assembly hole. In addition, the end face of the countersunk screw is a plane, and when the transmission shaft is installed in place, the transmission shaft can be in surface contact with the end face of the countersunk screw, and the countersunk screw plays a better role in limiting the installation of the transmission shaft.

[0011] The preferred solution of the above technical solution is: there are two grooves, and the two grooves are symmetrically distributed along the circumference of the first fixing hole. The symmetrical arrangement of the two grooves allows the two grooves to be arranged opposite to each other in the through direction thereof, making it easier to deform the connecting shaft section toward the handle, and at the same time, the structural strength of the rotating member itself can be better guaranteed.

[0012] A preferred embodiment of the above technical solution is that the rotating member is a metal member, and the rotating member is metallized to improve the structural strength of the rotating member itself, thereby improving the reliability of the fixed connection between the rotating member and the handle through the fastener.

[0013] The preferred scheme of the above technical scheme is: a first positioning plane is provided on the outer peripheral surface of the connecting shaft segment, and a second positioning plane corresponding to the first positioning plane is provided on the hole wall of the assembly hole of the handle. The first positioning plane is in surface contact and cooperation with the second positioning plane, and plays a positioning role when the connecting shaft segment is inserted into the assembly hole of the handle.

[0014] The preferred embodiment of the above technical solution is: the handle lock for doors and windows also includes a transmission shaft, the transmission shaft is a square shaft, a square connection hole matching the transmission shaft is provided in the rotating member, and one end of the square connection hole extends axially to the first fixing hole. In this way, after the transmission shaft is inserted into the square connection hole, the end of the transmission shaft can be inserted into the end plate of the connecting shaft section until the transmission shaft abuts against the fastener, so that there is a longer matching length between the transmission shaft and the hole wall of the square connection hole, so that the rotation member and the transmission shaft are reliably fixed, thereby improving the reliability of torque transmission between the rotation member and the transmission shaft.

[0015] The preferred solution of the above technical solution is: the four corners of the square connection hole are provided with trimming portions, the transmission shaft has a shaft assembly section inserted into the square connection hole, the shaft assembly section includes an unchamfered shaft section and a chamfered shaft section connected in sequence, the unchamfered shaft section is arranged at one end of the chamfered shaft section away from the first fixing hole; the outer periphery of the unchamfered shaft section has four corner portions, the corner portions make the unchamfered shaft section and the square connection hole fit tightly; the four edges of the chamfered shaft section are provided with chamfered portions, at least a part of the unchamfered shaft section is inserted into the square connection hole of the connecting shaft section. In this way, the setting of the chamfered portion on the chamfered shaft section facilitates the insertion of the chamfered shaft section into the square connection hole; the setting of the unchamfered shaft section can eliminate the gap between it and the hole wall of the square connection hole, so that the unchamfered shaft section and the hole wall of the square connection hole are more tightly and firmly combined, avoiding the loosening of the transmission shaft during use.

[0016] The preferred scheme of the above technical scheme is: the transmission shaft is provided with a protrusion on the outer surface of the chamfered shaft section; when the transmission shaft is inserted into the square connecting hole, the protrusion causes the connecting shaft section to be deformed toward the handle, further eliminating the gap that may exist between the connecting shaft section and the handle; after the transmission shaft is installed in the square connecting hole, the protrusion is located in the square connecting hole of the connecting shaft section and abuts against the inner circumferential surface of the connecting shaft section, so that the chamfered shaft section and the connecting shaft section are tightly and firmly connected.

[0017] The preferred solution of the above technical solution is: a positioning shaft section protruding toward the handle is provided on the outer surface of the base, and a positioning groove distributed at the end of the assembly hole is opened at the end of the handle. The positioning shaft section is accommodated in the positioning groove, and the two are rotatably matched, which plays a positioning role when the handle is installed without affecting the subsequent rotation of the handle.

[0018] As described above, the door and window handle lock according to the present invention has the following beneficial effects:

[0019] The present application forms a groove body on the connecting shaft section of the rotating part by slotting the connecting shaft section. When the fastener is used to fix the connecting shaft section and the handle, the fastener will squeeze the connecting shaft section in the direction close to the handle, causing the connecting shaft section to deform in the direction close to the handle, thereby eliminating any gap that may exist between the connecting shaft section and the handle, and making the outer peripheral surface of the connecting shaft section contact and cooperate with the wall surface of the assembly hole, thereby greatly improving the firmness of the fixed connection between the rotating part and the handle, avoiding loosening of the handle, and ensuring the accuracy and reliability of the handle driving the rotating part to rotate synchronously.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0088] The present application relates to the technical field of door and window accessories, and in particular to a handle lock for doors and windows.

[0089] like Figure 1 and Figure 2 As shown, the handle lock for doors and windows involved in the present application includes a base 10, a rotating member 20, a handle 30, a fastener 40 and a transmission shaft 50. For the convenience of description, in the following embodiments, the definitions of various directions are as follows: the axial direction of the rotating member 20 is defined as the front-to-back direction, and the front-to-back direction is also the indoor and outdoor direction, and the front direction is the outdoor side direction, and the rear direction is the indoor side direction. Based on this, Figure 4 and Fig.10 In the views shown, the left side of the paper is the front direction, and the right side of the paper is the rear direction.

[0090] like Figure 1 , Figure 2 and Figure 6As shown, the base 10 is provided with a mounting hole 102 and a rotating hole 103 both extending axially forward and backward. The base 10 is fixed to the frame of the door and window by means of screws inserted in the mounting hole 102, thereby installing the door and window handle lock on the frame of the door and window. The rotating hole 103 is arranged at the center of the base 10; the rotating member 20 extends axially forward and backward, and the rotating member 20 is rotatably assembled in the rotating hole 103 of the base 10; the handle 30 is distributed on the rear end side of the base 10; the rear end of the rotating member 20 is fixedly connected to the handle 30 by means of a fastener 40. The transmission shaft 50 extends axially forward and backward, and the transmission shaft 50 and the rotating member 20 are arranged coaxially. The rear section of the transmission shaft 50 is fixedly inserted in the rotating member 20, and the two cooperate to transmit torque. The front section of the transmission shaft 50 extends forward from the rotating member 20 and is used to connect the transmission mechanism. When the door and window handle lock is in use, the user holds and rotates the handle 30, and the handle 30 drives the rotating member 20 and the transmission shaft 50 to rotate together, and the transmission shaft 50 drives the transmission mechanism to operate. When the handle 30 is rotated to rotate the rotating member 20 and the transmission shaft 50 together to the unlocking position, the door and window can be opened; when the handle 30 is rotated to rotate the rotating member 20 and the transmission shaft 50 together to the locking position, the door and window are closed.

[0091] Furthermore, if Figures 3 to 5 ,as well as Fig.11 As shown, the rotating member 20 has a connecting shaft section 21 extending straightly forward and backward, at least a part of the connecting shaft section 21 extends backward from the base 10, and this part of the connecting shaft section 21 is located outside the base 10 and inserted into the handle 30, and the handle 30 is provided with an assembly hole 31 for accommodating the part of the connecting shaft section 21 extending backward from the base 10. A first fixing hole 22 matching with the fastener 40 is provided at the rear end of the connecting shaft section 21; a second fixing hole 32 matching with the fastener 40 is provided in the handle 30, and the second fixing hole 32 is distributed at the rear end of the assembly hole 31, and the two are connected; after the connecting shaft section 21 is inserted into the assembly hole 31 of the handle 30, the first fixing hole 22 and the second fixing hole 32 are opposite to each other and are connected.

[0092] In particular, Figures 7 to 10 As shown, the present application makes a groove on the connecting shaft section 21 of the rotating member 20, so that a groove body 23 is formed on the connecting shaft section 21, and the groove body 23 penetrates the connecting shaft section 21 along the wall thickness direction of the connecting shaft section 21, and one end of the groove body 23 extends to the first fixing hole 22 and communicates with the first fixing hole 22. During the assembly process of the handle lock for doors and windows, the rotating member 20 is first pressed backward into the rotating hole 103 of the base 10, and then the fastener 40 is used to fix the rear end of the rotating member 20 with the handle 30. In this process, the fastener 40 is screwed into the first fixing hole 22 of the connecting shaft section 21 and the second fixing hole 32 of the handle 30 in turn. When the fastener 40 is screwed backward, as shown in FIG. Figure 5As shown, the fastener 40 will press the rear end portion of the connecting shaft segment 21 near the first fixing hole 22 outwardly, so that the rotating member 20 is subjected to force. By setting the groove body 23 on the connecting shaft segment 21, when the fastener 40 presses the connecting shaft segment 21 outwardly, the connecting shaft segment 21 is allowed to deform outwardly in the direction close to the handle 30 at the position of the groove body 23. The outward deformation includes the outer peripheral surface of the connecting shaft segment 21 deforming in the radial direction close to the hole wall of the assembly hole 31, and the rear end surface of the connecting shaft segment 21 deforming in the axial direction close to the handle 30. The bottom surface of the assembly hole 31 is deformed in the direction of the hole, so that the outer diameter of the rear end of the connecting shaft segment 21 becomes larger, thereby eliminating the possible gap between the connecting shaft segment 21 and the handle 30, so that the outer circumferential surface of the connecting shaft segment 21 is in close contact with the hole wall of the assembly hole 31, so that the rotating part 20 and the handle 30 have an interference fit and no gap, thereby greatly improving the firmness of the fixed connection between the rotating part 20 and the handle 30, avoiding the handle 30 from loosening, and ensuring the accuracy and reliability of the handle 30 driving the rotating part 20 to rotate synchronously.

[0093] Preferably, if Figure 1 and Figure 2 As shown, the door and window handle lock also includes two covers 60, which are respectively fixed at the two ends of the rear side of the base 10 and cover the two end structures of the rear side of the base 10, thereby improving the appearance of the door and window handle lock.

[0094] Furthermore, the structure of the connecting shaft section 21 is preferably: Figures 7 to 10 As shown, the connecting shaft section 21 includes a cylindrical portion 211 extending straight forward and backward along the axial direction of the rotating member 20, and an end plate portion 212 arranged at the rear end of the cylindrical portion 211 near the second fixing hole 32. The first fixing hole 22 is opened in the end plate portion 212 and passes through the end plate portion 212 front to back. The rear end surface of the end plate portion 212 is a plane, and it is in surface contact when it abuts against the bottom surface of the assembly hole 31 in the handle 30.

[0095] Furthermore, if Figures 7 to 10As shown, there are two slots 23 provided on the connecting shaft section 21, and the two slots 23 are symmetrically distributed along the circumference of the first fixing hole 22, and the two slots 23 are distributed at an interval of 180°. The symmetrical arrangement structure of the two slots 23 enables the two slots 23 to be arranged opposite to each other in the through direction thereof, so that the deformation of the connecting shaft section 21 in the direction close to the handle 30 is more easily achieved, and the structural strength of the rotating member 20 can also be better guaranteed. Preferably, each slot 23 is a narrow slot structure, that is, each slot 23 includes a first slot section 231 and a second slot section 232 connected to each other, the first slot section 231 is provided on the barrel portion 211 and extends straightly forward and backward along the axial direction of the barrel portion 211, the second slot section 232 is provided on the end plate portion 212 and extends straightly along the radial direction of the first fixing hole 22, and the second slot section 232 extends from one end of the first slot section 231 to the first fixing hole 22 and communicates with the first fixing hole 22. In this way, the processing of the groove body 23 is facilitated, and the structural strength of the rotating member 20 itself can be ensured, thereby improving the reliability of the fixed connection between the rotating member 20 and the handle 30.

[0096] Furthermore, in this embodiment, the fastener 40 is a screw, preferably a countersunk screw; Figure 4 , Figure 5 and Fig.10 As shown, the countersunk screw includes a screw head 41 and a screw shank 42 connected front and back. The screw head 41 is conical, and its outer diameter gradually decreases from front to back. The outer peripheral surface of the screw shank 42 is tapped with threads. The first fixing hole 22 includes a tapered hole section 221 and a straight hole section 222 connected front and back. The tapered hole section 221 is adapted to the screw head 41, and the aperture of the tapered hole section 221 gradually decreases from front to back, and the straight hole section 222 extends straightly front and back. After the countersunk screw fixes the end plate 212 at the rear end of the rotating member 20 with the handle 30, the screw head 41 is accommodated in the tapered hole section 221, and the outer peripheral surface of the screw head 41 is in conical contact with the hole wall of the tapered hole section 221, and the screw shank 42 is penetrated in the straight hole section 222 and the second fixing hole 32. Therefore, the straight hole section 222 is a through hole or a threaded hole matched with the screw shank 42, and the second fixing hole 32 is a threaded hole matched with the screw shank 42. In the process of screwing the countersunk screw backward into the first fixing hole 22 and the second fixing hole 32, the screw head 41 squeezes the wall of the tapered hole section 221, which more effectively drives the rear section of the connecting shaft section 21 to deform outward, so that the outer peripheral surface of the connecting shaft section 21 can be closely attached to the wall of the assembly hole 31 in the handle 30, thus eliminating the gap between the connecting shaft section 21 and the wall of the assembly hole 31. The front end surface of the countersunk screw is a plane. When the transmission shaft 50 is installed backward in place, as shown in FIG. Figure 4 and Figure 5 As shown, the rear end surface of the transmission shaft 50 and the front end surface of the countersunk screw can be in surface contact, and the countersunk screw can better play a limiting role when the transmission shaft 50 is installed.

[0097] Furthermore, based on the structure in which the rotating part 20 and the handle 30 are fixedly connected by countersunk screws, the present application metallizes the rotating part 20, and the rotating part 20 is a metal part made of metal, thereby improving the structural strength of the rotating part 20 itself, and also improving the reliability of the fixed connection between the rotating part 20 and the handle 30 by the countersunk screws.

[0098] Furthermore, if Figure 4 and Fig.11 As shown, the rear surface of the base 10 is provided with a positioning shaft section 101 protruding backward toward the handle 30, and the front end of the handle 30 is provided with a positioning groove 34 distributed at the front end of the assembly hole 31, and the positioning shaft section 101 is accommodated in the positioning groove 34, and the two are rotatably matched. In this way, through the mutual cooperation of the positioning shaft section 101 and the positioning groove 34, the handle 30 is positioned when it is installed, and the subsequent rotation of the handle 30 is not affected.

[0099] Furthermore, if Figure 8 As shown, four first positioning planes 24 are arranged uniformly distributed in the circumferential direction on the outer circumferential surface of the connecting shaft section 21; Fig.11 As shown, the handle 30 is provided with four circumferentially uniformly distributed second positioning planes 33 on the hole wall of the assembly hole 31, and the four first positioning planes 24 correspond to the four second positioning planes 33 one by one and are in surface contact. In this way, when the connecting shaft section 21 is inserted into the assembly hole 31 of the handle 30, or the handle 30 is sleeved on the connecting shaft section 21, the first positioning planes 24 and the second positioning planes 33 can play a better positioning role, and when the handle 30 is subsequently rotated, the torque can also be better transmitted to ensure that the rotating member 20 rotates synchronously with the handle 30. In addition, the first slot sections 231 of the two slot bodies 23 are on two of the first positioning planes 24, which is convenient for the processing of the first slot sections 231.

[0100] Furthermore, if Fig.12 As shown, the transmission shaft 50 is a square shaft, and its cross section is square; Figure 7 and Fig.10 As shown, a square connection hole 25 is provided in the rotating member 20 to match the transmission shaft 50. The square connection hole 25 extends straightly forward and backward. The front end of the square connection hole 25 passes through the rotating member 20 forward, and the rear end of the square connection hole 25 extends axially backward to the first fixing hole 22. The rotating member 20 has trimmed edges at the four corners of the square connection hole 25, so that the four corners of the square connection hole 25 have trimmed portions 251. The transmission shaft 50 is tightly mounted in the square connection hole 25 of the rotating member 20. After the transmission shaft 50 is inserted into the square connection hole 25, as shown in FIG. Figure 4 and Figure 5As shown, the end of the transmission shaft 50 is inserted backward into the end plate portion 212 of the connecting shaft section 21 until the transmission shaft 50 abuts against the countersunk screw, thereby allowing a longer fitting length between the transmission shaft 50 and the hole wall of the square connecting hole 25, so that the rotating member 20 and the transmission shaft 50 are reliably fixed, thereby improving the reliability of torque transmission between the rotating member 20 and the transmission shaft 50.

[0101] Furthermore, if Fig.12 As shown, the rear section of the transmission shaft 50 is a shaft assembly section 51 inserted into the square connection hole 25, and the shaft assembly section 51 includes an unchamfered shaft section 52 and a chamfered shaft section 53 connected in sequence front and back, and the unchamfered shaft section 52 is far away from the first fixing hole 22, and the chamfered shaft section 53 is close to the first fixing hole 22. The unchamfered shaft section 52 means that the edges of the shaft assembly section 51 are not chamfered, and the outer periphery of the unchamfered shaft section 52 has four corner portions 521; the chamfered shaft section 53 means that the edges of the shaft assembly section 51 are chamfered, so that the four edges of the chamfered shaft section 53 are all provided with chamfered portions 531; in this embodiment, the chamfered portion 531 is a circular arc chamfer. By setting the lengths of the unchamfered shaft segment 52 and the chamfered shaft segment 53 , at least a portion of the unchamfered shaft segment 52 is inserted backward into the square connecting hole 25 of the connecting shaft segment 21 , while the chamfered shaft segment 53 is fully inserted into the square connecting hole 25 of the connecting shaft segment 21 . When the transmission shaft 50 is installed in the rotating member 20, the chamfered portion 531 on the chamfered shaft segment 53 is arranged to avoid interference between the edge of the chamfered shaft segment 53 and the trimmed portion 251 of the square connection hole 25, thereby facilitating the insertion of the chamfered shaft segment 53 into the square connection hole 25; the corner portion 521 on the unchamfered shaft segment 52 is arranged to make the corner portion 521 of the unchamfered shaft segment 52 interfere with the trimmed portion 251 of the square connection hole 25, thereby making the unchamfered shaft segment 52 and the square connection hole 25 tightly fit, effectively eliminating the gap between the transmission shaft 50 and the hole wall of the square connection hole 25, making the unchamfered shaft segment 52 and the hole wall of the square connection hole 25 more tightly and firmly combined, and preventing the transmission shaft 50 from loosening. In a specific embodiment, the depth of the square connection hole 25 is 20.7 mm, the length of the chamfered shaft segment 53 of the shaft assembly segment 51 is 8 mm, and the length of the unchamfered shaft segment 52 of the shaft assembly segment 51 is 12.7 mm.

[0102] Furthermore, if Figure 5 and Fig.12As shown, the transmission shaft 50 is provided with a protrusion 54 on the outer surface of the chamfered shaft section 53. When the transmission shaft 50 is inserted backward into the square connection hole 25, the protrusion 54 interferes with the hole wall of the square connection hole 25, and the protrusion 54 causes the connecting shaft section 21 to deform in the radial direction toward the handle 30, further increasing the outer diameter of the rear end of the connecting shaft section 21, further eliminating the possible gap between the connecting shaft section 21 and the handle 30, and making the rotating member 20 and the handle 30 fit more tightly. After the transmission shaft 50 is installed in the square connection hole 25, the protrusion 54 is located in the square connection hole 25 of the connecting shaft section 21 and abuts against the inner circumference of the connecting shaft section 21, so that the chamfered shaft section 53 and the connecting shaft section 21 are tightly and firmly combined, which is conducive to the reliable transmission of torque. Based on this, the setting of the protrusion 54 should meet the following conditions: 1. The protrusion 54 protrudes radially along the connecting shaft segment 21, and the protruding direction of the protrusion 54 is perpendicular to the groove body 23; 2. Among the four outer surfaces of the chamfered shaft segment 53, two outer surfaces face the first groove segment 231 of the groove body 23, and the protrusion 54 is integrally arranged on the other two surfaces of the chamfered shaft segment 53 that are not facing the first groove segment 231; 3. In the front-to-back direction, the protrusion 54 is distributed between the front end and the rear end of the first groove body 23; in this way, the protrusion 54 can better drive the connecting shaft segment 21 to deform outward.

[0103] Preferably, if Fig.12 As shown, the rear end of the protrusion 54 is an insertion guide surface 541, which is an inclined surface, inclined in a direction closer to the central axis of the transmission shaft 50 as it moves backward. The inclined setting of the insertion guide surface 541 facilitates the installation of the transmission shaft 50 in the square connection hole 25.

[0104] Furthermore, if Figure 1 , Figure 2 and Figure 6 As shown, the door and window handle lock also includes two sets of sleeved sliders 70 and springs 80; two slide grooves 104 are opened in the base 10, and the two slide grooves 104 are evenly distributed on the outer periphery of the rotating hole 103. The outer ends of the slide grooves 104 extend to the rotating hole 103 and the two are connected. The center lines of the two slide grooves 104 are collinear, and the center lines of the slide grooves 104 pass through the center of the rotating hole 103; the spring 80 is accommodated in the slide groove 104, and the slider 70 is slidably assembled in the slide groove 104 along the extension direction of the slide groove 104. The two ends of the spring 80 are respectively in contact with the slider 70 and the base 10, and the spring 80 makes the outer end of the slider 70 contact the outer peripheral surface of the rotating member 20. Figure 8As shown, the outer circumferential surface of the rotating member 20 is provided with an opening slot 271 and a closing slot 272 which are spaced apart in the circumferential direction. When the user rotates the handle 30 to rotate the rotating member 20 and the transmission shaft 50 together to the unlocking position, the slider 70 is just engaged in the opening slot 271 on the outer circumference of the rotating member 20, thereby providing the user with a pause operation feeling when the door and window are opened by rotating the handle 30. When the user rotates the handle 30 to rotate the rotating member 20 and the transmission shaft 50 together to the locking position, the slider 70 is just engaged in the closing slot 272 on the outer circumference of the rotating member 20, thereby providing the user with a pause operation feeling when the door and window are closed by rotating the handle 30.

[0105] Furthermore, after the rotating member 20 is metallized, in order to reduce the wear of the slider 70 caused by the relative rotation with the rotating member 20, the present application sets the slider 70 as two independent parts. Figure 1 , Figure 2 and Figure 6 As shown, the slider 70 includes a slider main body 71 and a slider abutment 72 which are independent of each other. The slider abutment 72 is rotatably accommodated at the outer end of the slider main body 71, and the slider abutment 72 abuts against the outer peripheral surface of the rotating member 20, and the spring 80 abuts against the inner end of the slider main body 71. In particular, the slider main body 71 is a resin or plastic part, which is low in cost and easy to manufacture; the slider abutment 72 is a metal part, which itself has good wear resistance. The present application configures the slider 70 to be a slider main body 71 made of resin or plastic, and a slider abutment 72 made of metal, and only the slider abutment 72 made of metal abutments cooperates with the rotating member 20, while the slider main body 71 made of resin or plastic does not abuts with the rotating member 20; in this way, the pause operation feeling provided by the cooperation of the rotating member 20, the slider 70 and the spring 80 can be ensured, and the friction between the slider 70 and the rotating member 20 can be the friction between metal members, and the metalized slider abutment 72 and the rotating member 20 are both relatively wear-resistant, so that the slider 70 is durable as a whole, and the pause operation feeling provided by the door and window handle lock when the handle 30 is rotated can be reliably ensured.

[0106] Preferably, if Figure 2 and Figure 6 As shown, the slider abutment member 72 is a cylindrical member, and the central axis of the slider abutment member 72 is parallel to the central axis of the rotating member 20, and both extend straightly in the front-to-back direction. In this embodiment, the slider abutment member 72 is a steel column extending axially in the front-to-back direction.

[0107] Furthermore, the assembly structure between the slider body 71 and the slider abutment 72 is preferably as follows: Fig.13 and Fig.14As shown, the slider body 71 is provided with a groove 711 at the outer end facing the rotating member 20, and the slider body 71 is integrally provided with a circular support portion 712 at the rear end of the groove 711 near the bottom of the slide groove 104. At the same time, the slider body 71 is integrally provided with a wrapping portion 713 at the outer peripheral side of the groove 711 away from the rotating member 20. The inner peripheral surface of the wrapping portion 713 is a fan-shaped arc surface. The wrapping portion 713 at least covers part of the outer periphery of the groove 711, and the part of the outer periphery of the groove 711 not covered by the wrapping portion 713 forms a groove opening portion 714, and the groove opening portion 714 faces the rotating member 20. The slider abutment member 72 is accommodated in the groove 711 and placed on the support portion 712; the wrapping portion 713 covers part of the outer peripheral surface of the slider abutment member 72 to limit the slider abutment member 72; the outer peripheral surface of the slider abutment member 72 abuts against the outer peripheral surface of the rotating member 20 through the groove opening portion 714. The receiving groove 711 of the slider body 71 is an open structure, that is, the front end of the receiving groove 711 away from the support portion 712 penetrates the slider body 71 forward, so that it is easy to put the slider abutment 72 backward into the receiving groove 711. At the same time, the support portion 712 and the wrapping portion 713 cooperate to reliably retain the slider abutment 72 in the receiving groove 711, making it easier to assemble the door and window handle lock. In addition, after the slider abutment 72 adopts a cylindrical structure, it can easily realize that the slider abutment 72 is rotatably arranged in the receiving groove 711 of the slider body 71, and the slider abutment 72 and the support portion 712, and the slider abutment 72 and the wrapping portion 713 are both in surface contact, thereby improving the reliability of the slider abutment 72 being retained in the receiving groove 711.

[0108] Furthermore, the central angle of the portion of the outer circumference of the slider abutment 72 covered by the wrapping portion 713 is 210° to 250°, preferably 227°, that is, the central angle of the fan-shaped arc surface on the inner circumference of the wrapping portion 713 is 210° to 250°, preferably 227°, so that the width of the groove opening portion 714 is smaller than the diameter of the slider abutment 72 of the cylindrical structure, which can effectively prevent the slider abutment 72 from escaping outward from the receiving groove 711 along the extension direction of the slide groove 104.

[0109] Furthermore, if Figures 7 to 10As shown, the rotating member 20 is a stepped structure, and the rotating member 20 also includes an end cover 26 and a main shaft section 27. The end cover 26, the main shaft section 27 and the connecting shaft section 21 are sequentially connected from front to back. The outer diameters of the end cover 26, the main shaft section 27 and the connecting shaft section 21 decrease in sequence, so the outer periphery of the end cover 26 protrudes outwardly from the outer periphery of the main shaft section 27, and the outer periphery of the main shaft section 27 protrudes outwardly from the outer periphery of the connecting shaft section 21; the opening slot 271 and the closing slot 272 are both arranged on the outer periphery of the main shaft section 27. Correspondingly, the rotating hole 103 of the base 10 is a stepped hole, which includes a first hole portion that is rotatably matched with the end cover 26, a second hole portion that is rotatably matched with the main shaft section 27, and a third hole portion that is rotatably matched with the connecting shaft section 21, and the apertures of the first hole portion, the second hole portion and the third hole portion decrease in sequence.

[0110] After the rotating member 20 is installed in the base 10, Figure 4 and Figure 6 As shown, a gasket 90 is provided between the rear end face of the main shaft section 27 and the base 10, and the gasket 90 is sleeved on the outer periphery of the front end of the connecting shaft section 21; the slider abutment 72 abuts against the main shaft section 27 of the rotating member 20 through the groove opening portion 714, and the end cover portion 26 blocks part of the front end face of the slider abutment 72, then the end cover portion 26 limits the slider abutment 72, and prevents the slider abutment 72 from escaping forward from the receiving groove 711 of the slider main body 71, so that the slider abutment 72 is reliably retained in the receiving groove 711 of the slider main body 71, thereby reliably ensuring the pause operation feeling provided by the door and window handle lock when opening and closing the door and window.

[0111] Preferably, if Figure 8 As shown, a relief slope 273 is provided at the rear end of the outer periphery of the main shaft section 27 near the connecting shaft section 21. The relief slope 273 is inclined in a manner that the closer it is to the connecting shaft section 21, the farther it is from the support portion 712; and along the sliding direction of the slider 70, the relief slope 273 is arranged opposite to the support portion 712. The arrangement of the relief slope 273 makes the support portion 712 and the main shaft section 27 non-contact, so as to achieve the purpose of non-contact between the slider main body 71 made of resin or plastic and the metalized rotating member 20, greatly reducing the wear of the slider main body 71, and making the slider main body 71 durable.

[0112] Preferably, if Figure 6 , Fig.13 and Fig.14As shown, a guide rod section 715 is integrally provided on one side of the slider body 71 facing away from the slider abutment member 72, and the guide rod section 715 extends straight along the extension direction of the slide slot 104. The elastic member is a spring 80, and the guide rod section 715 is inserted into the spring 80. The guide rod section 715 cooperates with the spring 80 to reliably extend and retract the spring 80 along the extension direction of the slide slot 104, so that the spring force applied by the spring 80 to the slider body 71 is consistent with the extension direction of the slide slot 104, avoiding the occurrence of spring force components in other directions.

[0113] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
