Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

As shown in fig. 1 to 11, an embodiment of the present invention provides a handle device, which includes a handle part 100 and a transmission box 200 that can be embedded in a door and window profile 910, and the transmission box 200 can be clamped in an opening groove of the door and window profile 910. The handle part 100 is connected to the transmission case 200. The transmission box 200 includes a box body 210 and a transmission member 220 (in this embodiment, a rack) disposed in the box body 210, and the handling member 100 can drive the transmission member 220 to achieve opening and locking actions. The handle part 100 is provided with a linkage structure (in the embodiment, the tooth form 121 of the transmission tooth) which can be connected with the transmission part 220 to realize linkage, and because the handle part 100 is in linkage relation with the transmission part 220, the rotation angle of the handle part 100 corresponds to the movement position of the transmission part 220 one by one; the handle part 100 is provided with a clamping block 101, the transmission box 200 is provided with an assembling groove 201 for the clamping block 101 to pass through, and when the clamping block 101 passes through the assembling groove 201, the linkage structure (the tooth form 121) can be connected with the transmission piece 220 (the rack) at a set position, so that linkage is realized. Correspondingly, as shown in fig. 4, the handle part 100 also has an initial assembly angle (a set angle, which is also a limit position), and when the initial assembly position of the transmission part 220 corresponds to the initial assembly angle of the handle part 100, that is, when the transmission part 220 is at the initial assembly position and the handle part 100 is at the initial assembly angle, the handle part 100 can be mounted to the transmission case 200 (linked with the transmission part 220) or can be dismounted from the transmission case 200.

Specifically, when the handle 100 is at a set angle, the clamping blocks 101 may be aligned with the assembling grooves 201, and only when the transmission member 220 is at a set position, the handle 100 may be inserted into the transmission box 200 to be abutted with the transmission member 220 to achieve linkage. The transmission box 200 is provided with a limiting member 230, the limiting member 230 may be configured to limit the transmission member 220 to move to the set position, so as to prevent the clamping block 101 from aligning with the assembling groove 201, and a reset component 240 is further disposed in the transmission box 200, and the reset component 240 is configured to keep the limiting member 230 in a limiting state. That is, when the position limiting member 230 is in the position limiting state, the transmission member 220 cannot move to the set position, and the handle member 100 in the non-mounted state (when the handle member 100 is not assembled to the transmission box 200) cannot be connected to the transmission member 220 of the transmission member 220 to achieve the linkage. In the handle member 100 in the mounted state (when mounted to the transmission case 200), since the transmission member 220 cannot be moved to the set position, the handle member 100 cannot be rotated to the mounting initial angle (set angle, such as the angle of fig. 4), that is, the grip block 101 thereof cannot be aligned with the mounting groove 201, and the handle member 100 cannot be removed. The handle part 100 is rotated to the unlocking angle (the angle of fig. 6, the state of 0 degrees) and the locking angle (the angle of fig. 5, the state of 90 degrees), and the assembly initial angle (the set angle, the limit angle of fig. 6) is out of the range of the unlocking angle and the locking angle, without affecting the normal use of the handle part 100.

Specifically, when the position-limiting element 230 is in the non-limiting state, the transmission element 220 can move to the set position. When the handle part 100 is not mounted on the transmission box 200, the handle part 100 can be inserted into the transmission box 200 and connected with the transmission part 220 to realize linkage, at the moment, if the handle part 100 is continuously rotated, the transmission part 220 can be driven to leave the initial position, the handle part 100 also leaves the initial assembly angle, the clamping blocks 101 are staggered with the assembly grooves 201 and cannot leave the assembly grooves 201, and the handle part 100 and the transmission box 200 realize reliable linkage connection. After the transmission member 220 leaves the initial position, the reset component 240 enables the limiting member 230 to recover the limiting state, at this time, the transmission member 220 cannot move to the set position, the handle member 100 cannot rotate to the initial assembly angle shown in fig. 4, and can only rotate at the position between fig. 5 and fig. 6, and the handle member 100 cannot be separated from the transmission box 200.

The transmission case 200 is provided with an assembling groove 201 for allowing the clamping block 101 to pass through so that the linkage structure can be connected with the transmission member 220 located at a set position, i.e., an assembling initial position of the transmission member 220, and correspondingly, the handle member 100 also has an assembling initial angle (a set angle, which is also a limit position), and the handle member 100 can be mounted to the transmission case 200 or dismounted from the transmission case 200 when the assembling initial position corresponds to the assembling initial angle, i.e., when the transmission member 220 is located at the initial position and the handle member 100 is located at the assembling initial angle. Through the design, the base-free design of the handle device can be realized, the structure is simple, the cost is low, the installation is quick and reliable, a base is not required to be fixed through screws, the handle part 100 is not required to be connected with the transmission box 200 through the screws, the handle is directly pressed in the transmission box 200, and the transmission box is rotated for a certain angle, so that the fixation can be realized; can dismantle fast, conveniently change the handle, press the stopper in the transmission box 200 through the instrument, rotate the handle extremely spacing can extract the handle, and have the base handle more succinct pleasing to the eye in appearance relatively, user experience is good.

Specifically, when the position-limiting element 230 is in the non-limiting state, the transmission element 220 can move to the set position. In the first situation, the handle part 100 in the non-mounted state (not mounted in the transmission box 200) can be inserted into the transmission box 200 and connected with the transmission part 220 to realize linkage, at this time, if the handle part 100 is continuously rotated to drive the transmission part 220 to leave the initial position, the handle part 100 also leaves the initial assembly angle, the clamping block 101 is dislocated with the assembly groove 201 and cannot exit the assembly groove 201, and the handle part 100 and the transmission box 200 realize reliable linkage connection. After the transmission member 220 leaves the initial position, the transmission member 220 no longer restricts the limiting member 230, the reset component 240 restores the limiting member 230 to the limiting state, at this time, the transmission member 220 cannot move to the set position, and the handle member 100 cannot rotate to the initial assembly angle. In the second case, the grip piece 101 of the handle part 100 in the mounted state (when mounted to the transmission case 200) can be aligned with the mounting groove 201, and the handle part 100 can be pulled out of the transmission case 200 and removed to replace the handle part 100 with a new one.
