[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, 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 creative work are within the scope of protection of the utility model.
[0024] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.
[0025] like Figure 1-7 As shown, a door and window handle unlocked by a button 4 comprises:
[0026] A handle base 1, and a handle assembly that rotates with the handle base 1, the handle base 1 is provided with a lock sleeve 2, the handle assembly includes a handle body 3, and a button 4 arranged on one side of the rotation axis of the handle body 3, the button 4 is used to cooperate with the lock sleeve 2 to prevent the handle body 3 from rotating, keep the handle body 3 in a locked state, and unlock with the pressing of the button 4, so as to allow the handle body 3 to rotate, the handle body 3 is provided with a lock rod 5 arranged about its rotation axis, and the lock rod 5 controls the door and window to unlock with the rotation of the handle body 3;
[0027] like Figures 2 to 4As shown, the button 4 has a locking end 6 engaged with the lock sleeve 2, the locking end 6 extends into the handle body 3, and the locking end 6 is disengaged from the lock sleeve 2 by pressing the button 4, the button 4 receives a first resistance spring 7 in the handle body 3, and a second resistance spring 8 is provided between the locking end 6 and the handle seat 1, the first resistance spring 7 always applies a force to the button 4 to engage with the lock sleeve 2, the second resistance spring 8 specifically abuts against the end of the locking end 6, and the second resistance spring 8 applies a force to the locking end 6 to keep the lock sleeve 2 in cooperation with the lock sleeve 2 at least in the locked position of the handle body 3, so that under normal circumstances, the action of pressing the button 4 to disengage the locking end 6 from the lock sleeve 2 needs to overcome the two forces from the first resistance spring 7 and the second resistance spring 8.
[0028] Furthermore, the first resistance spring 7 is coaxial with the button 4 and the locking end 6 , and the axis of the second resistance spring 8 is parallel to the axis of the first resistance spring 7 , and is colinear with the rotation axis of the handle body 3 .
[0029] In other embodiments, the second resistance spring 8 may also be colinear with the first resistance spring 7 .
[0030] Specifically, the second resistance spring 8 is sleeved on the outside of the lock sleeve 2 and exposed on the lock sleeve 2 at any engagement position with the locking end 6, so that when the handle body 3 is rotated to any position, it is necessary to overcome the force of the first resistance spring 7 and the second resistance spring 8, and the engagement position of the lock sleeve 2 and the locking end 6 corresponds to the rotation position of the handle body 3 to control different opening states of the door and window.
[0031] Specifically, the outer edge of the lock sleeve 2 is provided with a plurality of locking grooves 2.1, the locking end 6 matches the contour of the locking groove 2.1, and prevents the handle body 3 from rotating at the engagement position, and the lock sleeve 2 is restricted from rotating on the handle base 1, so that each locking groove 2.1 corresponds to the above-mentioned engagement position.
[0032] Specifically, the locking sleeve 2 is engaged with the edge of the locking end 6 , and the second resistance spring 8 acts on the edge positions of the locking sleeve 2 and the locking end 6 and deviates from the actuation axis of the button 4 .
[0033] Therefore, even if the button 4 is released during the rotation of the handle body 3, the forces of the first and second resistance springs 8 will still lock the locking end 6 on the outer edge end surface of the lock sleeve 2 to further prevent the handle body 3 from rotating while providing a sense of rotation of the handle body 3.
[0034] As a further implementation of the cooperation between the locking end 6 and the handle body 3, the pressing axis of the button 4 is parallel to one side of the rotation axis of the handle body 3, and a limit seat 3.1 is provided in the handle body 3 for stopping the locking end 6 in the engagement position with the lock sleeve 2. The first resistance spring 7 and the second resistance spring 8 actuate the button 4 so that the locking end 6 abuts against the limit seat 3.1. Through the above improvements, the stability of the button 4 in the locked position can be maintained. At the same time, the limit seat 3.1 provides a contact surface for the locking end 6 to prevent the handle body 3 from being forcibly rotated by external force.
[0035] Furthermore, a radially extending convex edge 6.1 is provided on the locking end 6, and the convex edge 6.1 is axially opposed to the limiting seat 3.1 and matched with the locking groove 2.1 on the locking sleeve 2.
[0036] Among them, the second resistance spring 8 specifically acts on the convex edge 6.1, and an extended edge 2.2 is radially extended on the edge of the lock sleeve 2, and the locking groove 2.1 is arranged on the extended edge 2.2, so that the second resistance spring 8 can be reliably sleeved on the lock sleeve 2 and axially abut against the locking end 6. When the button 4 is released during the rotation of the handle body 3, the convex edge 6.1 and the end face of the extended edge 2.2 abut against each other in the axial direction to generate resistance.
[0037] In other embodiments, the second resistance spring 8 may also act on the axis of the locking end 6 .
[0038] Preferably, the second resistance spring 8 is always maintained in a compressed state, thereby increasing the resistance of the second resistance spring 8. Of course, the first resistance spring 7 can also be maintained in a compressed state, thereby ensuring that it is difficult for young children to actuate the button 4 to the unlocked position. However, even if the locking end 6 is axially disengaged from the lock sleeve 2, the button 4 still needs to be kept pressed to the unlocked position, otherwise it will still be subject to the friction between the locking end 6 and the end face of the lock sleeve 2.
[0039] Preferably, friction surfaces are provided on the end surfaces of the convex edge 6.1, the limiting seat 3.1 and the extended edge 2.2 to increase the rotation resistance.
[0040] As a further implementation of the handle body 3, an installation cavity 1.3 is provided on one side of the handle body 3 deviating from the rotation axis, and the button 4 is inserted into the installation cavity 1.3. The bottom of the installation cavity 1.3 constitutes a limit seat 3.1, and a guide hole is formed in the limit seat 3.1. The first resistance spring 7 abuts between one end face of the limit seat 3.1 and the inner end face of the button 4, and the small diameter portion of the locking end 6 passes through the guide hole of the limit seat 3.1. The convex edge 6.1, which is the large diameter portion of the locking end 6, abuts against the other end face of the limit seat 3.1 under the action of the first and second resistance springs 8. At the same time, the limit seat 3.1 provides guidance for the locking end 6 to ensure that the button 4 is actuated by axial pressing to prevent children from tilting the button 4 to the unlocked state.
[0041] The second resistance spring 8 abuts between the end faces of the handle base 1 and the locking end 6 , and in the locked state, the locking end 6 is flush with the extended edge 2 . 2 of the lock sleeve 2 , so the second resistance spring 8 also abuts against the end face of the lock sleeve 2 .
[0042] like Figure 7 As shown, specifically, the handle body 3 is further provided with a positioning groove toward the handle base 1, one end of the lock sleeve 2 cooperates with the inside of the handle base 1 and stops rotation through a concave-convex clamping structure, the other end of the lock sleeve 2 is inserted into the positioning groove, and the second resistance spring 8 is radially positioned between the positioning groove and the lock sleeve 2.
[0043] like Figure 5 and Figure 6 As shown, as a further improvement on the cooperation between the handle body 3 and the handle base 1, a damping member 9 is provided at the end of the handle body 3 and is inserted into the handle base 1. A stopper 1.1 engaged with the damping member 9 is provided in the handle base 1. The damping member 9 rotates synchronously with the handle body 3 and exerts resistance to prevent the handle body 3 from rotating by engaging with the stopper 1.1, thereby further improving the feel of the handle body 3 when rotating and preventing children from rotating the handle body 3.
[0044] like Figure 6 As shown, the damping member 9 is clamped on the end of the handle body 3 through a concave-convex structure and is colinear with the rotation axis of the handle body 3, so as to rotate synchronously with the handle body 3.
[0045] Specifically, the stopper 1.1 is relatively arranged on the outside of the damping member 9, so as to further increase the resistance to the damping member 9.
[0046] In this embodiment, the stopper 1.1 is configured to deform under the action of the rotation of the damping member 9, so that during the rotation of the handle body 3, the stopper 1.1 is driven to deform, and the restoring force of the stopper 1.1 further stops the damping member 9.
[0047] Specifically, the block seat 1.1 is arranged to protrude toward the damping member 9 in an arc shape, and a snap-on protrusion 1.2 is provided at the protruding end of the block seat 1.1, and a plurality of snap-on recesses 9.1 matching with the snap-on protrusion 1.2 are provided at the outer edge of the damping member 9. The disengagement and engagement of the snap-on recesses 9.1 and the snap-on protrusion 1.2 provide a feel and resistance for the handle body 3, and can maintain the handle body 3 in the current engagement position of the snap-on protrusion 1.2 and the snap-on recesses 9.1.
[0048] In addition, the corresponding number of the engaging recesses 9.1 and the engaging protrusions 1.2 may be multiple times the number of the locking grooves 2.1, so that the damping member 9 can provide sufficient resistance when the handle body 3 rotates from the current position to the next position.
[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
