Description

Technical Field

[0001] The utility model relates to the technical field of building door and window hardware fittings, and particularly relates to a handle with a hidden locking device. Background Art

[0002] With the improvement of people's living standards, people have higher and higher requirements for doors and windows. Taking safety as an example, in order to prevent young children from opening the window and falling out of the window, it is required that the window has a simple locking function. If a lock core is directly installed on the handle, it will have a greater impact on the appearance of the handle and the window. In the long term, there is also a risk of key loss. Therefore, a handle with a child safety lock appears. The existing handle with a child safety lock uses a steel ball spring for positioning when locking. Due to the limited internal space of the handle itself, the steel ball and the spring are relatively small, making it difficult to pick up. Moreover, the steel ball is spherical, and the rolling range is large after dropping, which leads to low production efficiency of the handle.

[0003] Therefore, this application designs a handle with a hidden locking device to solve the above problems. Content of the Utility Model

[0004] The utility model provides a handle with a hidden locking device to make up for the deficiencies in the prior art.

[0005] A handle with a hidden locking device includes a control rod, a compression spring, a decorative cover, a base assembly, a gear member, a slider, a positioning member, and a T-shaped block, and is characterized in that:

[0006] The positioning member is an irregular-shaped positioning member, which is installed on the slider and used for positioning the slider when locking or unlocking.

[0007] Further, in order to better implement the utility model, the control rod is in an L-shaped structure, one end of its short side is provided with a cylinder, and an axial protrusion is provided at the root of the cylinder, and the cylinder passes through the decorative cover.

[0008] Further, in order to better implement the utility model, a first round hole is opened in the center of the decorative cover, a circular ring is provided in the center of the base assembly, the first round hole is sleeved outside the circular ring, the cylinder is inserted inside the circular ring, and a compression spring is sleeved outside the circular ring, and the compression spring is arranged between the control rod and the decorative cover.

[0009] Further, in order to better implement the utility model, the gear member is in a flange shape, its thin-walled end is provided with an axial depression, and the other end is provided with a radial depression. The thin-walled end is inserted into one side of the circular ring in the center of the base assembly, and the axial depression at the thin-walled end fits with the axial protrusion at the root of the cylinder of the control rod.

[0010] Furthermore, to better implement the present utility model, the base is generally provided with a slideway, a positioning groove is arranged on one side of the slideway, and a long slot is provided at the bottom of the slideway; one end of the slider is provided with a boss. When the slider slides along the slideway on the base, the boss slides into the radial depression on the gear member, restricting the rotation of the joystick and the gear member to achieve the locking function.

[0011] Furthermore, to better implement the present utility model, a second round hole is arranged at the other end of the slider, and the T-shaped block sequentially passes through the long slot at the bottom of the slideway on the base and the round hole on the slider; a clamping groove is arranged in the middle of the slider, and the positioning member is fixed on the clamping groove and clamped between the slider and the base.

[0012] Furthermore, to better implement the present utility model, a positioning post is arranged in the middle of the positioning member, and the positioning post cooperates with the positioning groove on the side of the slideway on the base for positioning the slider when locking or unlocking.

[0013] Furthermore, to better implement the present utility model, when the handle is opened, the positioning post stays in the positioning groove A. By pushing the T-shaped block, the slider will be driven to slide along the slideway on the base until the positioning post on the positioning member slides to the positioning groove B. At this time, the boss on the slider inserts into the radial depression on the gear member, restricting the rotation of the joystick and the gear member to achieve the locking function.

[0014] The beneficial effects of the present utility model are:

[0015] Compared with the conventional handle with a child safety lock that uses a steel ball spring for positioning, the present utility model adopts a positioning member with a special-shaped body, which is convenient to pick up, has no rolling, has a simpler structure, and has high production efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Figures 1-6 For a specific embodiment of the present invention, this embodiment is a handle with a hidden locking device. As shown in the figure, the joystick 1 is L-shaped, and a cylinder 11 is provided at one end of the short side. There is an axial protrusion 12 at the root of the cylinder 11.

[0027] A round hole 31 is provided at the center of the decorative cover 3. A ring 41 is provided at the center of the base assembly 4. The round hole 31 at the center of the decorative cover 3 is sleeved outside the ring 41. The cylinder 11 at one end of the short side of the joystick 1 is inserted into the inside of the ring 41. The compression spring 2 is sleeved outside the ring 41 and is arranged between the joystick 1 and the decorative cover 3. The gear member 5 is in a flange shape, with an axial depression 51 at the thin-walled end and a radial depression 52 at the other end. It is inserted into the other side of the ring 41 at the center of the base assembly 4 from the thin-walled end, and the axial depression 51 at the thin-walled end fits with the axial protrusion 12 at the root of the joystick cylinder.

[0028] A slideway 42 is provided on the base assembly 4. A positioning groove 43 is provided on one side of the slideway 42, and a long slot 44 is provided at the bottom of the slideway 42. One end of the slide block 6 is provided with a boss 61. When the slide block 6 slides along the slideway 42 on the base assembly 4, the boss 61 slides into the radial depression 52 on the gear member 5 to limit the rotation of the joystick 1 and the gear member 5, realizing the locking function.

[0029] At the other end of the slider 6, there is a round hole 62. The T-shaped block 8 sequentially passes through the long hole 44 at the bottom of the slideway 42 on the overall base 4 and the round hole 62 on the slider 6. A clamping groove 63 is provided in the middle of the slider 6. The positioning member 7 is fixed on the clamping groove 63 and is clamped between the slider 6 and the overall base 4. A positioning post 71 is provided in the middle of the positioning member 7. The positioning post 71 cooperates with the positioning groove 43 on the side of the slideway 42 on the overall base 4 to position the slider 6 when locking or unlocking.

[0030] When the handle is opened, the positioning post 71 on the positioning member 7 stays in the positioning groove A431. By pushing the T-shaped block 8, the slider 6 will be driven to slide along the slideway 42 on the overall base 4 until the positioning post 71 on the positioning member 7 slides into the positioning groove B432. At this time, the boss 61 on the slider 6 is inserted into the radial depression 52 on the gear member 5, restricting the rotation of the operating lever 1 and the gear member 5, and realizing the locking function.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
