Description

Technical Field

[0001] The utility model relates to a lock, in particular to an elastically mounted lock button structure. Background Art

[0002] Generally, interior doors have a safety button. Once the door is locked from the inside using the safety button, the door cannot be opened by turning the door handle from the outside.

[0003] The structure of the safety button generally includes a button cap and a button rod. A handle tube is provided in the door handle. During assembly, the button rod is inserted into the handle tube from one end, and then the retaining spring is clamped into the retaining spring groove of the button rod from the other end of the handle tube, so that the retaining spring can be against the door handle. The safety button cannot fall out of the handle tube and can be rotated due to the restriction of the retaining spring and the button cap.

[0004] The retaining spring in the above structure is difficult to install because the handle tube is relatively long and of small diameter, resulting in limited operating space. Furthermore, the retaining spring is installed deep near the bottom of the handle tube, making manual operation difficult. Therefore, the applicant has designed a resiliently mounted lock knob structure to address the above problems. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an elastically mounted lock button structure.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A elastically mounted lock button structure includes a safety button and a door handle, wherein the safety button includes a button cap and a button rod, and the door handle is provided with a handle tube and a button hole that passes through the handle tube. The structure is characterized in that an elastic locking piece is provided on the button rod, and the button rod can be inserted into the button hole and the handle tube through the deformation of the elastic locking piece, and the elastic locking piece can be locked with the door handle to prevent the button rod from falling out of the handle tube.

[0008] The elastic clamping member includes relatively arranged spring sheets, which are arranged at an angle and protrude from the outer surface of the button rod. The elastic clamping member also includes an upper piece and relatively arranged side pieces. The spring sheets are connected to the ends of the side pieces. A mounting hole is provided on the button rod. The elastic clamping member is located in the mounting hole. The spring sheet can be pressed into the mounting hole when squeezed.

[0009] The side pieces are arranged obliquely to form a truncated triangular structure with the upper piece.

[0010] The elastic sheet is connected to the end portion of the side sheet through the lower sheet.

[0011] The end of the elastic sheet is provided with a bent foot plate, and the foot plate can be abutted against the door handle.

[0012] The door handle is provided with a handle groove, and the handle tube is located at the groove bottom of the handle groove.

[0013] The beneficial effects of this utility model are as follows: It utilizes a combination of an elastic retaining member and a knob rod for assembly. During installation, the elastic retaining member can be fully utilized to deform and insert into the handle tube. After the deformation is restored, the elastic retaining member can be reengaged with the door handle. This simple structure is easy to assemble; simply inserting the knob rod into the handle tube allows for a one-step assembly, eliminating the need for a retaining spring for securing. This significantly improves installation efficiency and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As will be fully appreciated by those skilled in the art, the features of the different embodiments of the present disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0028] Reference Figures 1 to 6 The utility model discloses an elastically mounted lock button structure, including a safety button 1 and a door handle 2. The safety button 1 and the door handle 2 are preferably formed by metal die-casting. The safety button 1 includes a button cap 3 and a button rod 4. The door handle 2 is provided with a handle tube 5 and a button hole 6 that passes through the handle tube 5. The door handle 2 is provided with a handle groove 7. The handle tube 5 is located at the bottom of the handle groove 7, thereby realizing a lightweight design of the door handle 2. The button rod 4 is a round rod, and the diameter of the button cap 3 is larger than that of the button rod 4 and the button hole 6, so that the button cap 3 abuts against the outer wall of the door handle 2. The button rod 4 is provided with an elastic stopper, which is a metal part. When the button rod 4 is inserted into the handle tube 5, the deformation of the elastic stopper can avoid being stuck with the button hole 6 and the handle tube 5, thereby realizing the installation of the button rod 4 and the elastic stopper; after being inserted into the handle tube 5, the elastic stopper restores the deformation and can be against the inner surface of the door handle 2, thereby limiting the separation of the safety button 1 from two directions along the handle tube 5 through the button cap 3 and the elastic stopper, thereby achieving the purpose of preventing the safety button 1 from falling off, but the safety button 1 can rotate freely.

[0029] As shown in the figure, the elastic retaining member includes relatively arranged spring pieces 8, which are arranged at an angle and protrude from the outer surface of the button rod 4, thereby forming a cone with the button rod 4, and the width gradually decreases from the button cap 3 to the end of the button rod 4. Of course, the distance between the ends of the two spring pieces 8 is greater than the diameter of the button hole 6, and the diameter of the tube hole of the handle tube 5 is greater than the diameter of the button hole 6. In this way, when the elastic retaining member is inserted into the handle tube 5 along with the button rod 4, the hole wall of the button hole 6 will gradually squeeze the spring piece 8 along the spring piece 8 to make it bend and deform until the spring piece 8 completely enters the tube hole of the handle tube 5, and then restore the deformation. The ends of the two spring pieces 8 are opened and can be against the inner surface of the door handle 2.

[0030] As a preferred structure, the elastic locking member includes an upper piece 9 and relatively arranged side pieces 10, the spring piece 8 is connected to the end of the side piece 10, and the button rod 4 is provided with a mounting hole 11, which is specifically a square hole, and the square hole passes through the button rod 4 horizontally. The elastic locking member is located in the mounting hole 11, and the spring piece 8 can be pressed into the mounting hole 11 when squeezed. The upper piece 9 and the two side pieces 10 not only constitute the main support frame of the elastic locking member, so that they can be directly placed in the mounting hole 11 during installation, and the support frame can cooperate with the installation to achieve the purpose of installation and positioning of the elastic locking member, but also the side piece 10 itself is also an elastic plate with elasticity, so it can cooperate with the spring piece 8 to adjust the overall elasticity, and can also reduce the length of the spring piece 8, so that even if the spring piece 8 is relatively hard, it will not affect the overall elasticity, thereby facilitating installation.

[0031] As a specific structure, the elastic piece 8 is connected to the end of the side piece 10 through the lower piece 12. In this way, the support frame is added with the lower piece 12, thereby increasing the contact surface with the bottom surface of the mounting hole 11, thereby improving stability and preventing the elastic retaining piece from being dislodged from the mounting hole 11 due to shaking during installation. As a further mechanism, the side piece 10 is arranged at an angle, thereby forming a triangular structure with the upper piece 9 without the top. This prevents the lower piece 12 from being exposed outside the mounting hole 11 and causing interference during installation.

[0032] As shown in the figure, a bent foot plate 13 is provided at the end of the spring piece 8, and the foot plate 13 can be against the door handle 2. The foot plate 13 increases the contact area with the door handle 2 and increases friction, thereby increasing the ability of the spring piece 8 to resist the tensile lateral bending deformation of the safety button 1.

[0033] The above is a detailed introduction to an elastically mounted lock button structure provided in an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
