Description

Technical Field

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

[0002] Handle locks are one of the main accessories for doors and windows. Generally, handle locks for doors and windows mainly include a base fixed on the door and window frame, a rotating member rotatably assembled in the base, and a handle fixed to the rotating member. Users can conveniently open and close doors and windows by holding and rotating the handle of the handle lock.

[0003] In the process of rotating the handle to open and close the doors and windows, in order to provide an operational feel, the door and window handle lock is also equipped with at least one set of sliders and springs. An opening positioning groove and a closing positioning groove are provided on the outer circumference of the rotating part. The two ends of the spring are respectively in contact with the base and the slider, and the spring makes the slider contact the outer circumference of the rotating part. In this way, when the handle is rotated to the unlocked position to open the doors and windows, the slider is just stuck in the opening positioning groove, providing a paused operating feel; similarly, when the handle is rotated to the locked position to close the doors and windows, the slider is just stuck in the closing positioning groove, providing a paused operating feel. For example, the rotary password handle disclosed in the Chinese utility model patent with application number 201820780693.4.

[0004] When assembling the above-mentioned door and window handle lock, it is necessary to first press the slider and the spring into the slide groove of the base, and then press the rotating part into the hole of the base. This is a secondary pressing operation and the assembly time is long. In addition, it is difficult to press in the slider and auxiliary tools such as clamps are required. Summary of the invention

[0005] 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 can assemble the rotating part and the sliding block into place by pressing them in once, thereby facilitating assembly.

[0006] To achieve the above-mentioned object, the present invention provides a handle lock for doors and windows, comprising a base, a rotating member, and at least one group of abutting and matching sliders and elastic members, wherein a connecting rotating hole and a slide groove are provided in the base, the rotating member is rotatably mounted in the rotating hole, the slider is movably mounted in the slide groove, the elastic member is accommodated in the slide groove, one end of the elastic member away from the slider is in contact with the base, one end of the slider away from the elastic member is in contact with the outer peripheral surface of the rotating member, a positioning protrusion is fixed on the outer surface of the slider facing the slide groove wall, and a supporting arm is provided on the base at the end of the slide groove;

[0007] When the rotating member is not pressed into the base, the positioning protrusion abuts against the supporting arm;

[0008] When the rotating member is pressed into the base, the positioning protrusion is accommodated in the sliding groove.

[0009] When assembling the present application, first put the slider and the elastic member into the slide groove of the base, so that the positioning protrusion abuts against the support arm, and the base has a certain supporting effect on the slider, so that the slider and the elastic member are temporarily placed on the base; then, press the rotating member, and during the process of pressing the rotating member, the rotating member will press the slider into the slide groove. Therefore, the present application only needs to press once to assemble the rotating member and the slider into place, eliminating the assembly operation of pressing the slider into the slide groove first, thereby simplifying the assembly process, facilitating assembly, and improving assembly efficiency.

[0010] In the above-mentioned door and window handle lock, the base is used to be fixed on the frame of the door and window, and the rotating member is used to be fixedly connected with the handle of the door and window handle lock by screws. When the user holds the handle and rotates the handle, the handle drives the rotating member to rotate in the rotating hole of the base. Preferably, the rotating member is a metal member, and the rotating member is metalized to improve the structural strength of the rotating member itself, thereby improving the reliability of the screw-fixed connection between the rotating member and the handle.

[0011] The preferred solution of the above technical solution is: the slider includes a slider body and a slider abutment, the slider abutment is rotatably accommodated in the slider body and abuts against the outer peripheral surface of the rotating part, the elastic part abuts against the slider body, the slider body is a resin part or a plastic part, and the slider abutment is a metal part. In this way, the slider abutment is also metallized, and when the slider abutment and the rotating part rotate relative to each other, the friction between metal parts and metal parts occurs, and the metallized slider abutment and the rotating part are both relatively wear-resistant, so that the slider as a whole is durable, and the pause operation feeling provided by the handle lock for doors and windows is reliably guaranteed.

[0012] The preferred embodiment of the above technical solution is as follows: the slider body is provided with a receiving groove, a support portion fixed at one end of the receiving groove near the bottom of the slide groove, and a wrapping portion fixed at the outer periphery of the receiving groove, the portion of the outer periphery of the receiving groove not covered by the wrapping portion forms a groove opening portion facing the rotating member, the slider abutment is received in the receiving groove and placed on the support portion, the wrapping portion covers part of the outer peripheral surface of the slider abutment, and the outer peripheral surface of the slider abutment abuts against the outer peripheral surface of the rotating member through the groove opening portion. Therefore, the receiving groove of the slider body is an open structure, and the end of the receiving groove away from the support portion passes through the slider body, which is convenient for placing the slider abutment into the receiving groove. At the same time, the support portion and the wrapping portion cooperate to reliably keep the slider abutment in the receiving groove, which is convenient for assembling the handle lock for doors and windows.

[0013] A preferred embodiment of the above technical solution is that the central angle of the outer circumferential surface of the slider abutment covered by the wrapping portion is 210° to 250°, which can effectively prevent the slider abutment from escaping from the receiving groove.

[0014] The preferred solution of the above technical solution is: the slider abutment is a cylindrical member, and the central axis of the slider abutment is parallel to the central axis of the rotating member. In this way, it is easy to realize that the slider abutment is rotatably arranged in the receiving groove of the slider main body, and the slider abutment and the supporting part, and the slider abutment and the wrapping part are in surface contact, thereby improving the reliability of the slider abutment being retained in the receiving groove. In a specific embodiment, the slider abutment is a steel column.

[0015] The preferred embodiment of the above technical solution is as follows: the rotating member includes an end cover portion, a first shaft portion and a second shaft portion connected in sequence, and the outer diameters of the end cover portion, the outer diameters of the first shaft portion and the outer diameters of the second shaft portion decrease in sequence; accordingly, the rotating hole of the base is a stepped hole, which includes a first hole portion that is rotationally matched with the end cover portion, a second hole portion that is rotationally matched with the first shaft portion, and a third hole portion that is rotationally matched with the second shaft portion, and an opening positioning groove and a closing positioning groove are provided on the outer circumferential surface of the first shaft portion. When the rotating member is pressed into the base, the slider abutment member abuts against the first shaft portion. In this way, when the rotating member is driven to rotate to the unlocking position by the handle, the slider abutment member is engaged in the opening positioning groove, thereby providing the user with a pause operation feeling when the door and window are opened by rotating the handle; when the rotating member is driven to rotate to the locking position by the handle, the slider abutment member is engaged in the closing positioning groove, thereby providing the user with a pause operation feeling when the door and window are closed by rotating the handle. In addition, when the rotating part is pressed into the base, the end cover part blocks part of the end surface of the slider abutment part, and the end cover part limits the slider abutment part, preventing the slider abutment part from escaping from the receiving groove of the slider main body part, thereby reliably ensuring the pause operation feeling provided by the door and window handle lock when opening and closing the door and window.

[0016] A preferred solution of the above technical solution is: an escape slope is provided at one end of the outer periphery of the first shaft portion close to the second shaft portion, the escape slope is inclined in a manner that the closer it is to the second shaft portion, the farther it is from the support portion, and the escape slope is arranged opposite to the support portion. The arrangement of the escape slope prevents the support portion from contacting the first shaft portion, thereby preventing the slider body made of resin or plastic from contacting the metalized rotating part, greatly reducing the wear of the slider body, and making the slider body durable.

[0017] The preferred solution of the above technical solution is: a guide rod section is integrally provided on the side of the slider body member facing away from the slider abutment member, the guide rod section extends straightly along the extension direction of the slide slot, the elastic member is a spring, and the guide rod section is inserted into the spring. The guide rod section cooperates with the spring to reliably extend and retract the spring along the extension direction of the slide slot, so that the spring force applied by the spring to the slider body member is consistent with the extension direction of the slide slot, avoiding the occurrence of spring force components in other directions.

[0018] The preferred solution of the above technical solution is: the end face of the positioning protrusion facing the slide groove is the abutment end face, the abutment end face is an inclined face, and is inclined in a manner that the farther away from the slide groove bottom, the closer to the slide groove wall; when the rotating member is not pressed into the base, the abutment end face of the positioning protrusion abuts on the support arm. Afterwards, when the slider is pressed into the slide groove by pressing the rotating member, the inclination of the abutment end face provides a certain guiding effect, making it easier to press the slider into the slide groove, thereby improving assembly reliability.

[0019] The preferred solution of the above technical solution is: there are two positioning protrusions on the same outer surface of the slider, and they are arranged in parallel along the extension direction of the slide groove, and the positioning protrusions extend straight along the pressing direction of the rotating member. The two positioning protrusions on the same outer surface of the slider can, on the one hand, enable the slider to be pressed into the slide groove; on the other hand, after the slider is pressed into the slide groove, the positioning protrusions are in contact with the groove wall of the slide groove, which can reduce the contact area between the slider and the groove wall of the slide groove, improve the smoothness of the slider moving in the slide groove, and ensure the contact reliability between the slider and the groove wall of the slide groove, while achieving smooth and reliable sliding of the slider in the slide groove.

[0020] A preferred embodiment of the above technical solution is as follows: the slide groove includes a first groove section, a second groove section, and a limiting step portion formed at the junction of the first groove section and the second groove section, and the width of the first groove section is greater than the width of the second groove section; when the slider is pressed into the slide groove, the slider can be movably accommodated in the first groove section and can abut against the limiting step portion, thereby limiting the sliding range of the slider, so that the slider can only slide in the first groove section.

[0021] The preferred embodiment of the above technical solution is that: the base is provided with a baffle at the end of the slide groove away from the rotating member, and the baffle covers the end of the elastic member. When the rotating member is pressed into the base, the rotating member will simultaneously press the slider into the slide groove, thus driving the elastic member to compress. The baffle can prevent the end of the elastic member from being separated from the slide groove, thereby ensuring assembly reliability.

[0022] The present application also provides a method for installing the above-mentioned door and window handle lock, which comprises the following steps in sequence:

[0023] S1, placing a slider and an elastic member in the slide groove of the base, making the slider abut against the elastic member, making the positioning protrusion of the slider abut against the supporting arm of the base, and at least making one end of the elastic member away from the slider be placed in the slide groove, so that the slider and the elastic member are both in an inclined state relative to the slide groove, and the end of the slider away from the elastic member faces the rotating hole;

[0024] S2, placing a rotating member in the rotating hole of the base, wherein at least a portion of the rotating member is placed in the rotating hole, and an outer peripheral surface of the rotating member abuts against the slider;

[0025] S3. Press the rotating member into the rotating hole. During this process, the rotating member presses the slider into the sliding groove along its pressing direction, and the rotating member presses the slider into the sliding groove along the extending direction of the sliding groove. Then, the positioning protrusion is accommodated in the sliding groove, the slider and the elastic member are both accommodated in the sliding groove, the elastic member is in a compressed state, and the rotating member, the slider, the elastic member and the base are abutted in sequence.

[0026] As described above, the door and window handle lock and the installation method thereof according to the present invention have the following beneficial effects:

[0027] When assembling the present application, first put the slider and the elastic member into the slide groove of the base, so that the positioning protrusion abuts against the support arm, and the base has a certain supporting effect on the slider, so that the slider and the elastic member are temporarily placed on the base; then, press the rotating member, and during the process of pressing the rotating member, the rotating member will press the slider into the slide groove. Therefore, the present application only needs to press once to assemble the rotating member and the slider into place, eliminating the assembly operation of pressing the slider into the slide groove first, thereby simplifying the assembly process, facilitating assembly, and improving assembly efficiency.

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.

[0082] The present application relates to the technical field of door and window accessories, and in particular to a handle lock for doors and windows, and an installation method of the handle lock for doors and windows.

[0083] 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, at least one set of abutting sliders 30 and elastic members 40, a handle 50, and a transmission shaft 60. 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 6 and Fig. 9 In the views shown, the front side of the paper is the front direction, and the back side of the paper is the rear direction.

[0084] like Figure 8 and Fig. 9 As shown, the base 10 is provided with a fixing hole 15, a rotating hole 11 and a sliding groove 12 which are connected to each other. The base 10 is fixed to the frame of the door and window by screws passing through the fixing hole 15, thereby installing the door and window handle lock on the frame of the door and window. Figure 1 , Figure 2 and Figure 4 As shown, the rotating member 20 is rotatably mounted in the rotating hole 11 of the base 10, and the handle 50 is arranged on the rear end side of the base 10. The rear end of the rotating member 20 is fixedly connected to the handle 50 by a screw 70. The transmission shaft 60 and the rotating member 20 are coaxially arranged. The transmission shaft 60 is a square shaft with a square cross-section. A square hole 24 adapted to the transmission shaft 60 is opened in the rotating member 20. The rear section of the transmission shaft 60 is inserted into the square hole 24 of the rotating member 20. The two cooperate to transmit torque. The front section of the transmission shaft 60 is used to connect the transmission mechanism. The slider 30 is movably mounted in the slide groove 12 of the base 10. The elastic member 40 is accommodated in the slide groove 12. The two ends of the elastic member 40 are respectively abutted against the base 10 and the slider 30. The elastic member 40 makes the outer end of the slider 30 abut and cooperate with the outer peripheral surface of the rotating member 20. The outer end of the slider 30 is also the end of the slider 30 away from the elastic member 40. As shown Fig.10 As shown, the outer circumferential surface of the rotating member 20 is provided with an opening positioning groove 221 and a closing positioning groove 222 which are circumferentially staggered.

[0085] When the handle lock for doors and windows is in use, the user holds and rotates the handle 50, and the handle 50 drives the rotating member 20 and the transmission shaft 60 to rotate together, and the transmission shaft 60 drives the transmission mechanism to operate. When the handle 50 is rotated to rotate the rotating member 20 and the transmission shaft 60 together to the unlocking position, the doors and windows can be opened, and the slider 30 is just engaged in the opening positioning groove 221 on the outer periphery of the rotating member 20, thereby providing the user with a pause operation feeling when the handle 50 is rotated to open the doors and windows. When the handle 50 is rotated to rotate the rotating member 20 and the transmission shaft 60 together to the locking position, the doors and windows are closed, and the slider 30 is just engaged in the closing positioning groove 222 on the outer periphery of the rotating member 20, thereby providing the user with a pause operation feeling when the handle 50 is rotated to close the doors and windows.

[0086] In particular, Figure 3a , Fig.13 and Fig.14 As shown, the slider 30 is provided with a positioning protrusion 311 on the outer surface of the groove wall facing the groove 12, and the base 10 is provided with a supporting arm 13 at the outer end of the groove 12 near the rotating hole 11. When the rotating member 20 is not pressed into the base 10, as shown in FIG. Figure 3a As shown, the positioning protrusion 311 abuts against the support arm 13, thereby temporarily placing the slider 30 and the elastic member 40 on the base 10; when the rotating member 20 is pressed into the base 10, as shown in FIG. Figure 4 As shown, the rotating member 20 presses the slider 30 into the slide groove 12 , and the positioning protrusion 311 is accommodated in the slide groove 12 .

[0087] Furthermore, the present application also provides an installation method of the above-mentioned door and window handle lock, which is mainly an assembly method between the base 10, the rotating member 20, the slider 30 and the elastic member 40, which comprises the following steps in sequence:

[0088] Step S1: Figure 3a As shown, the slider 30 and the elastic member 40 are placed in the slide groove 12 of the base 10, so that the slider 30 abuts against the elastic member 40, the positioning protrusion 311 of the slider 30 abuts against the support arm 13 of the base 10, and at least the end of the elastic member 40 away from the slider 30 is placed in the slide groove 12, so that the slider 30 and the elastic member 40 are temporarily placed on the base 10, and the end of the slider 30 away from the elastic member 40 faces the rotating hole 11. Since the positioning protrusion 311 of the slider 30 abuts against the support arm 13 of the base 10, the slider 30 and the elastic member 40 are both in a forward tilted state relative to the slide groove 12.

[0089] Step S2: Figure 3bAs shown, the rotating member 20 is placed in the rotating hole 11 of the base 10 , and under the interference of the slider 30 , a part of the rotating member 20 is placed in the rotating hole 11 , and the outer peripheral surface of the rotating member 20 abuts against the slider 30 .

[0090] Step S3, the rotating member 20 is pressed backward into the rotating hole 11. During this process, the rotating member 20 presses the slider 30 backward into the slide groove 12 along the pressing direction. At the same time, the rotating member 20 also stretches the slider 30 outward, that is, the rotating member 20 also presses the slider 30 inward into the slide groove 12 along the extension direction of the slide groove 12. In this way, by pressing the rotating member 20 backward once, the rotating member 20 and the slider 30 can be pressed into place. After the rotating member 20 and the slider 30 are pressed into place, as shown in FIG. Figure 4 As shown, the positioning protrusion 311 on the outer surface of the slider 30 is accommodated in the slide groove 12, and the slider 30 and the elastic member 40 are both accommodated in the slide groove 12. The slider 30 compresses the elastic member 40 during the press-fitting process, and the elastic member 40 is in a compressed state; and the rotating member 20, the slider 30, the elastic member 40 and the base 10 are abutted in sequence.

[0091] Therefore, the present application provides a positioning protrusion 311 on the slider 30 that can abut against the base 10, so that the base 10 has a certain supporting effect on the slider 30. When assembling the slider 30, the elastic member 40 and the rotating member 20, the slider 30 and the elastic member 40 can be temporarily placed on the base 10 through the abutment of the positioning protrusion 311 and the support arm 13; thereafter, the rotating member 20 is pressed in, and the slider 30 is pressed into the slide groove 12 at the same time during the process of the rotating member 20 being pressed backward. The rotating member 20 and the slider 30 can be assembled into place by pressing in once, eliminating the assembly operation of pressing the slider 30 into the slide groove 12 first, thereby simplifying the assembly process, facilitating assembly, and improving assembly efficiency.

[0092] Furthermore, if Figure 4 , Figure 8 and Fig. 9 As shown, the rotating hole 11 is set at the center of the base 10, and there are two slide grooves 12, which are symmetrically distributed on the outer peripheral side of the rotating hole 11. Then the center lines of the two slide grooves 12 are collinear, and the center line of the slide groove 12 passes through the center of the rotating hole 11. Based on this, there are two groups of abutting sliders 30 and elastic members 40, which are respectively accommodated in the two slide grooves 12. There are two opening positioning grooves 221 and two closing positioning grooves 222 on the outer peripheral surface of the rotating member 20, and the two opening positioning grooves 221 and the two closing positioning grooves 222 are evenly distributed alternately along the circumference of the rotating member 20. The slide groove 12 is a front open structure, and the rear end surface of the slide groove 12 is its groove bottom; along the width direction of the slide groove 12, the surfaces on both sides of the slide groove 12 are its groove walls.

[0093] Preferably, if Figure 1 and Figure 2As shown, the door and window handle lock also includes two covers 80, 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, since the rotating member 20 and the handle 50 are fixed by the screws 70 and the rotating member 20 is metallized, the rotating member 20 is a metal member made of metal, thereby improving the structural strength of the rotating member 20 itself, and also improving the reliability of the fixed connection between the rotating member 20 and the handle 50 by the screws 70.

[0095] After the rotating member 20 is metallized, in order to reduce the wear of the slider 30 caused by the relative rotation with the rotating member 20, the present application sets the slider 30 as two independent parts. Figures 2 to 7 As shown, the slider 30 includes a slider main body 31 and a slider abutment 32 which are independent of each other. The slider abutment 32 is rotatably accommodated at the outer end of the slider main body 31, and the slider abutment 32 abuts against the outer peripheral surface of the rotating member 20. The elastic member 40 abuts against the inner end of the slider main body 31, and the positioning protrusion 311 is integrally provided on the outer surface of the slider main body 31. In particular, the slider main body 31 is a resin part or a plastic part, which is low in cost and easy to manufacture; the slider abutment 32 is a metal part, which itself has good wear resistance. In the present application, the slider 30 is configured as a slider main body 31 made of resin or plastic, and a slider abutment 32 made of metal, and only the slider abutment 32 made of metal is abutted and matched with the rotating part 20, while the slider main body 31 made of resin or plastic is not abutted and matched with the rotating part 20; in this way, the pause operation feeling provided by the cooperation of the rotating part 20, the slider 30 and the elastic part 40 can be guaranteed, and the friction between the slider 30 and the rotating part 20 can be the friction between metal parts, and the metalized slider abutment 32 and the rotating part 20 are both relatively wear-resistant, so that the slider 30 is durable as a whole, and the pause operation feeling provided by the door and window handle lock when the handle 50 is rotated can be reliably guaranteed.

[0096] Preferably, if Figure 2 , Figure 3a and Figure 7 As shown, the slider abutment member 32 is a cylindrical member, and the central axis of the slider abutment member 32 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 32 is a steel column extending axially in the front-to-back direction.

[0097] Furthermore, the assembly structure between the slider body 31 and the slider abutment 32 is preferably as follows: Figures 11 to 14As shown, a receiving groove 312 is provided at the outer end of the slider body 31 facing the rotating member 20, and a circular supporting portion 313 is integrally provided at the rear end of the receiving groove 312 near the bottom of the slide groove 12. At the same time, a wrapping portion 314 is integrally provided at the outer peripheral side of the receiving groove 312 away from the rotating member 20. The inner peripheral surface of the wrapping portion 314 is a fan-shaped arc surface. The wrapping portion 314 at least covers part of the outer periphery of the receiving groove 312, and the part of the outer periphery of the receiving groove 312 not covered by the wrapping portion 314 forms a groove opening portion 315, and the groove opening portion 315 faces the rotating member 20. The slider abutting member 32 is accommodated in the receiving groove 312 and placed on the supporting portion 313; the wrapping portion 314 covers part of the outer peripheral surface of the slider abutting member 32 to limit the slider abutting member 32; the outer peripheral surface of the slider abutting member 32 abuts against the outer peripheral surface of the rotating member 20 through the groove opening portion 315.

[0098] In the present application, the receiving groove 312 of the slider body 31 is an open structure, that is, the front end of the receiving groove 312 away from the support portion 313 penetrates the slider body 31 forward, so that it is easy to put the slider abutment 32 backward into the receiving groove 312. At the same time, the support portion 313 and the wrapping portion 314 cooperate to reliably retain the slider abutment 32 in the receiving groove 312, making it easier to assemble the door and window handle lock. In addition, after the slider abutment 32 adopts a cylindrical structure, it can easily realize that the slider abutment 32 is rotatably arranged in the receiving groove 312 of the slider body 31, and the slider abutment 32 and the support portion 313, and the slider abutment 32 and the wrapping portion 314 are both in surface contact, thereby improving the reliability of the slider abutment 32 being retained in the receiving groove 312.

[0099] Preferably, the central angle of the portion of the outer circumference of the slider abutment 32 covered by the wrapping portion 314 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 314 is 210° to 250°, preferably 227°, so that the width of the groove opening portion 315 is smaller than the diameter of the slider abutment 32 of the cylindrical structure, which can effectively prevent the slider abutment 32 from escaping outward from the receiving groove 312 along the extension direction of the slide groove 12.

[0100] Furthermore, if Fig.10 As shown, the rotating member 20 is a stepped structure, and the rotating member 20 includes an end cover portion 21, a first shaft portion 22, and a second shaft portion 23 which are sequentially connected from front to back. The outer diameters of the end cover portion 21, the first shaft portion 22, and the second shaft portion 23 are sequentially reduced, so that the outer periphery of the end cover portion 21 protrudes outwardly from the outer periphery of the first shaft portion 22, and the outer periphery of the first shaft portion 22 protrudes outwardly from the outer periphery of the second shaft portion 23. Correspondingly, the rotating hole 11 of the base 10 is a stepped hole; Figure 8As shown, the stepped hole includes a first hole portion 111 rotatably matched with the end cover portion 21, a second hole portion 112 rotatably matched with the first shaft portion 22, and a third hole portion 113 rotatably matched with the second shaft portion 23, and the apertures of the first hole portion 111, the second hole portion 112, and the third hole portion 113 decrease in sequence. After the rotating member 20 is installed in the base 10, the end cover portion 21 is rotatably accommodated in the first hole portion 111, the first shaft portion 22 is rotatably accommodated in the second hole portion 112, and the second shaft portion 23 is rotatably accommodated in the third hole portion 113. Two opening positioning grooves 221 and two closing positioning grooves 222 are both provided on the outer peripheral surface of the first shaft portion 22, and the rear section of the second shaft portion 23 passes backwards from the third hole portion 113 and extends into the handle 50, and the rear end face of the second shaft portion 23 is fixed to the handle 50 by a screw 70. And, as shown in Figure 2 As shown, a gasket 90 is provided between the rear end surface of the first shaft portion 22 and the base 10 , and the gasket 90 is sleeved on the outer periphery of the front end of the second shaft portion 23 .

[0101] After the rotating member 20 is pressed into the base 10, the rotating member 20, the slider body 31 and the slider abutment 32 are all installed in place. Figures 5 to 7 As shown, the slider abutment 32 abuts against the first shaft portion 22 of the rotating member 20 through the slot opening 315, and in particular, the end cover 21 blocks part of the front end surface of the slider abutment 32, and the end cover 21 limits the slider abutment 32, preventing the slider abutment 32 from disengaging forward from the receiving groove 312 of the slider main body 31, so that the slider abutment 32 is reliably retained in the receiving groove 312 of the slider main body 31, and the door and window handle lock provides a pause operation feeling when opening and closing the door and window. In addition, in the process of pressing the rotating member 20 backward, the rotating member 20 will simultaneously press the slider main body 31 and the slider abutment 32 into place, the end cover 21 is limited at the front side of the slider abutment 32, and the support portion 313 is supported at the rear end of the slider abutment 32, effectively preventing the slider abutment 32 from turning outward during the pressing process.

[0102] Preferably, if Figure 5 , Figure 7 and Fig.10 As shown, a relief slope 223 is provided at the rear end of the second shaft portion 23 near the outer periphery of the first shaft portion 22, and the relief slope 223 is inclined in a manner that the closer it is to the second shaft portion 23, the farther it is from the support portion 313; and along the sliding direction of the slider 30, the relief slope 223 is arranged opposite to the support portion 313. The arrangement of the relief slope 223 makes the support portion 313 not contact the first shaft portion 22, so as to achieve the purpose of not contacting the slider body 31 made of resin or plastic with the metalized rotating member 20, greatly reducing the wear of the slider body 31, and making the slider body 31 durable.

[0103] Furthermore, if Figures 5 to 7 As shown, a guide rod section 316 is integrally provided on the side of the slider body 31 facing away from the slider abutment member 32, and the guide rod section 316 extends straight along the extension direction of the slide slot 12. The elastic member 40 is a spring 41, and the guide rod section 316 is inserted into the spring 41. The guide rod section 316 cooperates with the spring 41 to reliably make the spring 41 expand and contract along the extension direction of the slide slot 12, so that the spring force applied by the spring 41 to the slider body 31 is consistent with the extension direction of the slide slot 12, avoiding the occurrence of spring force components in other directions.

[0104] Furthermore, if Figures 11 to 13 As shown, two positioning protrusions 311 are integrally provided on the outer surfaces of both sides of the slider body 31 in the width direction of the slide groove 12, so there are four positioning protrusions 311 on the outer surface of the slider body 31. The two positioning protrusions 311 on each outer surface of the slider body 31 are arranged in parallel along the extension direction of the slide groove 12, and each positioning protrusion 311 extends straightly forward and backward along the pressing direction of the rotating member 20, and the positioning protrusion 311 is also a convex rib structure. The four positioning protrusions 311 are arranged on the outer surface of the slider body 31. On the one hand, the slider 30 can be pressed into the slide groove 12; on the other hand, after the slider 30 is pressed into the slide groove 12, the positioning protrusions 311 contact and cooperate with the groove wall of the slide groove 12 when the slider 30 slides, which can reduce the contact area between the slider 30 and the groove wall of the slide groove 12, improve the smoothness of the slider 30 moving in the slide groove 12, and ensure the contact reliability between the slider 30 and the groove wall of the slide groove 12, while realizing the smooth and reliable sliding of the slider 30 in the slide groove 12.

[0105] Furthermore, if Fig.13 and Fig.14 As shown, the rear end surface of each positioning protrusion 311 facing the slide groove 12 is an abutting end surface 317, and the abutting end surface 317 is an inclined surface, and is inclined in a manner that the farther away from the bottom of the slide groove 12, the closer to the groove wall of the slide groove 12. The abutting end surface 317 can be formed by chamfering the rear end of the positioning protrusion 311. When the rotating member 20 is not pressed into the base 10, as shown in FIG. Figure 3a As shown, the abutting end face 317 of the positioning protrusion 311 abuts against the support arm 13. Afterwards, when the slider 30 is pressed into the slide groove 12 by pressing the rotating member 20, the inclination of the abutting end face 317 provides a certain guiding effect, making it easier for the slider 30 to be pressed into the slide groove 12, improving the assembly reliability and facilitating the assembly. The front end of each positioning protrusion 311 is also chamfered, so that the front end face of each positioning protrusion 311 is an inclined surface, and is inclined in a manner that the farther away from the bottom of the slide groove 12, the farther away from the groove wall of the slide groove 12, that is, the front end face and the rear end face of the positioning protrusion 311 are in a symmetrical relationship. The inclined setting of the front end face of the positioning protrusion 311 facilitates the removal of the slider body 31 from the slide groove 12, and thus facilitates the replacement of the slider body 31.

[0106] Furthermore, if Figure 4 and Fig. 9 As shown, the slide groove 12 includes a first groove section 121, a second groove section 122, and a limiting step portion 123 formed at the junction of the first groove section 121 and the second groove section 122. The width of the first groove section 121 is greater than the width of the second groove section 122. When the slider 30 is pressed into the slide groove 12, the slider 30 can be movably accommodated in the first groove section 121 and can abut against the limiting step portion 123, thereby limiting the sliding range of the slider 30, so that the slider 30 can only slide in the first groove section 121.

[0107] Furthermore, if Figure 3a , Figure 3b and Figure 4 , Figure 8 and Fig. 9 As shown, the base 10 is integrally provided with a baffle 14 at the end of the slide slot 12 away from the rotating member 20, and the baffle 14 covers the end of the spring 41 away from the slider 30, that is, the baffle 14 is distributed on the front side of the end of the spring 41. When the rotating member 20 is pressed into the base 10, the rotating member 20 will simultaneously press the slider 30 into the slide slot 12, which also drives the spring 41 to compress. The baffle 14 can prevent the end of the spring 41 from escaping forward from the slide slot 12, thereby ensuring assembly reliability.

[0108] In summary, the assembly process of the door and window handle having the above structure is as follows.

[0109] First, the spring 41 is sleeved on the guide rod section 316 of the slider body 31 , and the slider abutment member 32 is placed in the receiving groove 312 of the slider body 31 to obtain a primary assembly component.

[0110] Second, if Figure 3a As shown, a primary assembly component is placed in each of the two slide grooves 12 of the base 10, and the abutting end surface 317 of the rear end of the positioning protrusion 311 on the outer periphery of the slider body 31 abuts against the support arm 13 at the outer end of the slide groove 12, and the end of the spring 41 is inserted into the inner end of the slide groove 12 and placed on the rear side of the baffle 14, and the end of the spring 41 is blocked by the baffle 14. In this way, the primary assembly component is temporarily placed on the base 10, and the primary assembly component is in a tilted state with the inner end tilted forward relative to the slide groove 12.

[0111] Third, if Figure 3b As shown, the rotating part 20 is placed in the rotating hole 11 of the base 10, and a gasket 90 is pre-placed in the rotating hole 11 of the rotating part 20. The rotating part 20 abuts against the outer end of the slider main body 31 and the outer end of the slider abutment 32, that is, the slider main body 31 and the slider abutment 32 interfere with the backward insertion of the rotating part 20.

[0112] Fourth, the rotating member 20 is pressed backward into the rotating hole 11 of the base 10, and the rotating member 20 simultaneously presses the slider body 31 and the slider abutment 32 backward into the slide groove 12, and presses the slider body 31 and the slider abutment 32 inward into the slide groove 12. By pressing the rotating member 20 backward once, the rotating member 20, the slider body 31 and the slider abutment 32 are pressed into place, and the spring 41 is compressed.

[0113] Fifth, the rear end of the rotating member 20 is fixedly connected to the handle 50 using the screw 70 .

[0114] Sixth, install the transmission shaft 60 into the square hole 24 of the rotating member 20 .

[0115] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0116] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
