AI Technical Summary
[0002]铝合金门常常使用手柄配合门锁来方便其开启和锁闭，平常手柄是为了方便开启门窗时抓握施力移动门窗，但是在特殊条件下，例如家中无人需要将门窗锁闭，或者家中有小孩时，为了防止小孩随意开启门窗，可能产生的翻越门窗导致的安全隐患，这就需要将门窗进行锁闭；目前常常是门窗锁与手柄分体设计，也就是门窗锁安装在手柄以外的位置，这就增加了安装的工作量，并且使用和操作不方便
[0009]本实用新型相比现有技术突出且有益的技术效果是：通过在手柄上设置锁壳以及锁芯，在锁芯上设置引导槽和限位段，在锁壳上设置限位槽，销轴与定位柱连接，并且沿限位槽滑动，底座上设置限位孔，并且锁芯与手柄的旋转轴偏心设置；锁芯可在钥匙的带动下相对锁壳正向或反向旋转，销轴便会沿引导槽的螺旋面移动，进而带动定位柱沿锁芯的轴向向上或向下移动，那么当顺时针转动钥匙，销轴会向上移动使得定位柱由底座的限位孔内移出，此时手柄解除了限制，便可以转动，实现开启或关闭门窗；相反的，当钥匙带动锁芯逆时针旋转是，销轴沿引导槽的螺旋面下移，带动定位柱下移插入底座的限位孔内，此时手柄无法转动，实现了上锁，此时无法通过转动手柄开启门窗；由此，便可以通过转动手柄开启或者锁闭门窗。

Description
Technical Field
[0001] This utility model belongs to the technical field, specifically relating to a handle with a knob-type lock cylinder. Background Technology
[0002] Aluminum alloy doors often use handles in conjunction with door locks to facilitate opening and locking. Normally, the handle is for gripping and applying force when opening and closing doors and windows. However, in special circumstances, such as when no one is home and the doors and windows need to be locked, or when there are children in the house, it is necessary to lock the doors and windows to prevent children from opening the doors and windows at will and causing safety hazards such as climbing over them. Currently, door and window locks are often designed separately from the handles, meaning that the door and window locks are installed in a location other than the handles. This increases the workload of installation and makes it inconvenient to use and operate. Summary of the Invention
[0003] The purpose of this utility model is to provide a handle with a rotary lock cylinder, which is intended to enable convenient and quick locking and unlocking of doors and windows.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A handle with a rotary lock cylinder includes a handle, a base, a lock housing, a lock cylinder, and a pin. The handle has a rotating head and a lock body mounting cavity. The lock body mounting cavity is eccentrically positioned with respect to the rotating head and has a through hole at the end opposite to the rotating head. The base has a rotating head connection channel and a limiting hole. The lock housing has a lock cylinder mounting cavity and a limiting groove formed on its inner circumferential surface. The lock housing is mounted within the lock body mounting cavity. The lock cylinder is movably mounted on the lock cylinder. Inside the cylinder mounting cavity, the lock cylinder has a spiral guide groove and a keyhole. The upper edge of the guide groove has a limiting section. The pin passes through the guide groove and its outer end is received in the limiting groove. The lock cylinder has a positioning post at the end opposite to the keyhole. The key passes through the through hole and can rotate the lock cylinder to move the pin along the spiral surface of the guide groove. The pin is connected to the positioning post, which in turn drives the positioning post to insert into or pull out of the limiting hole.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the lock cylinder and the positioning pin are provided with a positioning pin mounting hole at the connection end, the positioning pin mounting hole extends toward the guide groove and communicates with both; the positioning pin is inserted into the positioning pin mounting hole at this end, and a pin hole is provided at this end, the end of the pin away from the lock shell is inserted into the pin hole.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: it further includes a positioning seat and a sprocket, the positioning seat is mounted on the base, one end of the rotating head passes through the rotating head connecting channel, and the sprocket is connected to that end; the positioning seat is provided with a spring piece, and the spring piece contacts the teeth of the sprocket.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the spring is provided with a protrusion, and the protrusion is engaged between the teeth of the eight-petal gear.
[0008] Based on the above solution and as a preferred embodiment of the above solution: it further includes a plastic spring pad, which is sleeved on the outside of the rotating head and located between the handle and the base.
[0009] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: By setting a lock shell and a lock cylinder on the handle, a guide groove and a limiting section are set on the lock cylinder, and a limiting groove is set on the lock shell. A pin is connected to a positioning post and slides along the limiting groove. A limiting hole is set on the base, and the rotation axis of the lock cylinder and the handle are eccentrically set. The lock cylinder can rotate relative to the lock shell in a forward or reverse direction under the action of the key. The pin will then move along the spiral surface of the guide groove, thereby driving the positioning post to move upward or downward along the axial direction of the lock cylinder. When the key is turned clockwise, the pin will move upward, causing the positioning post to move out of the limiting hole in the base. At this time, the handle is released from restriction and can be rotated to open or close the door or window. Conversely, when the key drives the lock cylinder to rotate counterclockwise, the pin moves downward along the spiral surface of the guide groove, causing the positioning post to move downward and insert into the limiting hole in the base. At this time, the handle cannot be rotated, thus locking the door or window. Therefore, the door or window can be opened or locked by turning the handle. Attached Figure Description

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0013] See details Figure 1-5As shown, this application discloses a handle with a rotary lock cylinder, including a handle 1, a base 4, a lock housing 8, a lock cylinder 9, and a pin 12; the handle 1 is provided with a rotating head 101 and a lock body mounting cavity, the lock body mounting cavity is eccentrically positioned with respect to the rotating head 101 and a through hole 102 is provided at the end opposite to the rotating head 101; the base 4 is provided with a rotating head connecting channel and a limiting hole 41; the lock housing 8 is provided with a lock cylinder mounting cavity 801 and a limiting groove 802 formed on the inner circumferential surface of the lock housing 8; the lock housing 8 is installed in the lock body mounting cavity; the lock cylinder 9 is movably disposed in the lock cylinder mounting cavity 801, the lock housing is sleeved on the outside of the lock cylinder 9, the upper end of the lock cylinder 9 is provided with a flange or annular protrusion, and the lower end of the lock cylinder 9 is provided with a retaining groove 903, into which a retaining spring 10 is engaged, so that the lock cylinder can rotate while... The lock cylinder 9 is axially limited relative to the lock housing 8. A spiral guide groove 902 and a keyhole 903 are provided on the lock cylinder 9. A limiting section 902b is provided at the upper end of the guide groove 902. The pin 12 passes through the guide groove 902, and its outer end is received within the limiting groove 802. A positioning post 11 is provided at the end of the lock cylinder 9 opposite to the keyhole 903. The key 15 passes through the through hole 102 to rotate the lock cylinder 9, causing the pin 12 to move along the spiral surface of the guide groove 902. The pin 12 is connected to the positioning post 11. Specifically, a positioning post mounting hole is provided at the connection end between the lock cylinder 9 and the positioning post 11. The positioning post mounting hole extends towards the guide groove 902 and communicates with both. The positioning post 11 is inserted into the positioning post mounting hole at this end, and a pin hole 1101 is provided at this end. The end of the pin 12 opposite to the lock housing 8 is inserted into the pin hole 1101. In addition, the limiting groove 802 is preferably connected to the upper end of the lock shell 8 so that the pin 12 can be smoothly assembled and limited in the limiting groove 802 when the lock cylinder 8 is installed. By setting a lock shell and a lock cylinder on the handle, a guide groove and a limiting section are set on the lock cylinder, and a limiting groove is set on the lock shell. The pin is connected to the positioning pin and slides along the limiting groove. A limiting hole is set on the base, and the rotation axis of the lock cylinder and the handle are eccentrically set. The lock cylinder can rotate relative to the lock shell in the forward or reverse direction under the action of the key. The pin will move along the spiral surface of the guide groove, thereby driving the positioning pin to move upward or downward along the axial direction of the lock cylinder. When the key is turned clockwise, the pin will move upward, causing the positioning pin to move out of the limiting hole in the base. At this time, the handle is released from the restriction and can be rotated to open or close the door or window. Conversely, when the key drives the lock cylinder to rotate counterclockwise, the pin moves downward along the spiral surface of the guide groove, causing the positioning pin to move downward and insert into the limiting hole in the base. At this time, the handle cannot be rotated, and the lock is achieved. At this time, the door or window cannot be opened by turning the handle. Then, the positioning pin 11 is inserted into or pulled out of the limiting hole 401. Thus, the door or window can be opened or locked by turning the handle.
[0014] Furthermore, to clearly perceive the rotation position when rotating the handle 1 and to maintain the handle in the current rotation position, this embodiment also includes a positioning seat 5 and a zigzag gear 7. The positioning seat 5 is mounted on the base 4, and one end of the rotating head 101 passes through the rotating head connecting channel, with the zigzag gear 7 connected to that end. The rotating head 101 has a hexagonal outer contour, and the zigzag gear 7 has a hexagonal hole, thus the hexagonal shape of the rotating head 101 is embedded in the hexagonal hole of the zigzag gear 7, thereby driving the zigzag gear 7 to rotate synchronously when the handle is rotated. A spring piece 51 is provided on the positioning seat 5, and the spring piece 51 contacts the teeth of the zigzag gear 7. More preferably, the spring piece 7 is provided with a protrusion, and the protrusion is engaged between the teeth of the zigzag gear 7. When the handle 1 is rotated, the rotating head 101 drives the eight-pronged gear 7 to rotate. The teeth of this gear press against the protrusion, causing the spring 7 to elastically deform inwards. This allows the protrusion to disengage from between adjacent teeth and spring into the next pair of adjacent teeth, creating a distinct tactile feedback. After the handle stops rotating, the spring retains the protrusion pressed between the teeth, maintaining its current position. The position of the eight-pronged gear 7 also limits the rotation of the handle's rotating head, for example, by using a lateral screw, preventing the rotating head from separating from the eight-pronged gear after installation.
[0015] In addition, to maintain a good feel and smooth rotation of the handle, this embodiment also includes a plastic spring pad 2, which is sleeved on the outside of the rotating head 101 and located between the handle 1 and the base 4. The plastic spring pad 2 separates the handle 1 from the base 4. To improve aesthetics and product consistency, this embodiment also includes a base cover plate 3, which covers the mounting screw holes on the base. Of course, the base cover plate 3 has a clearance hole 301 that matches the limiting hole, so that the positioning pin can be smoothly inserted into the limiting hole.
[0016] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
