Description

Clutch device for door handle lock and door lock with replaceable door handle direction

technical field

The utility model relates to the field of door locks, in particular to a clutch device of a door handle lock and a door lock capable of changing the direction of the door handle.

Background technique

There are many types of door locks. With the rapid development of electronic technology, smart door locks are more convenient to use, illegally opened, and intelligent management than traditional mechanical locks. More and more families use smart door locks. Since the door is divided into left-handed and right-handed according to the direction of door opening in actual use, the handle of the door lock on the door is also divided into left-handed or right-handed. When matching, the door lock cannot be used. There are also some door locks with dual-purpose door handle structures on the market, which can be used for opening the door from the left and opening the door from the right. However, most of these dual-purpose door handle structures have complex structures, many components, and the reversing process is cumbersome.

Chinese patent number CN206874056U, free reversing handle, the patent discloses a free reversing handle, including: a handle; a panel, provided with a first through hole for the handle to pass through; a return torsion spring, located on the panel and located in the first through hole Outside, its two ends are crossed and arranged symmetrically; the clutch outer shift fork is connected and fixed through the return torsion spring and the handle, and there is a push block on the side close to the return torsion spring, and the push block is placed at a distance between the two ends of the return torsion spring The large side is offset against one end of the return torsion spring; the square shaft and the limit block, the limit block is set in the clutch outer shift fork, the limit block is provided with a second through hole for the square shaft to pass through, and the second pass The side wall of the hole is provided with a right-angled fan-shaped stopper, and the position corresponding to the square shaft and the stopper is provided with an L-shaped vacancy; the clutch inner shift fork is fixed on the panel, and it is provided with a square through slot matching the square shaft. The freely reversible handle provided by this patent does not distinguish between directions, can be adjusted according to the actual door opening direction, and is compatible with various door opening methods. However, the clutch device of the door handle lock of this patent has a lot of drilling. When the door handle changes direction, the square shaft and the clutch internal shift fork fixed on the panel need to be disassembled, and the handle is turned according to the direction of the door opening, and then installed. Square shaft, then fit the clutch inner shift fork with the square shaft and then fix it on the panel to complete the reversing. There are many parts to be disassembled, and it is not easy to maintain the initial position of the door handle during installation. In fact, the inner side of the panel is generally fixed with a cover plate that matches the panel. Therefore, in the above operation process, the cover plate needs to be disassembled first, and then the cover plate is fixed on the panel after the reversing is completed. Therefore, the whole commutation process is troublesome. In addition, the L-shaped vacancy does not match the shape of the square shaft. There are more gaps in the second through hole. The square shaft is not stable, which affects the sensitivity of the handle rotation. When the center point of the stopper withstands the square shaft and circles the center When the point is rotated, it is easy to cause friction between the square shaft and the inner wall of the second through hole during the use of the product, resulting in debris, thereby affecting the service life of the product.

Chinese Patent No. CN206942352U, a door handle structure with convenient reversing, the patent discloses a door handle structure with convenient reversing, the main point of the technical solution is to include a panel, and handles are respectively arranged on the panels 1. The first transmission block and the second transmission block that can be rotated by the handle, the second transmission block is provided with a gap, and the first transmission block is provided with a gap that can be inserted into the second transmission block when unlocking so that the second transmission block is used by the first The transmission block drives the bolt that rotates in the forward direction to unlock the lock. There is an outer protrusion on the outer wall of the second transmission block, and an inner protrusion that can fit with the outer protrusion on the first transmission block and drive the second transmission block to rotate in the opposite direction for anti-locking. There are two convex parts, the notch and the convex part are provided with two, the two notches are arranged on the second transmission block at 90 degrees, and the two convex parts are also arranged on the second transmission block at 90 degrees. On the second transmission block. When the door handle of the utility model needs to be used in reverse, it is only necessary to turn the second transmission block 90 degrees so that the other notch is aligned with the latch. The above-mentioned technical solution does not disclose how the handle is returned after turning, and in the actual reversing of the patent, it is necessary to remove the cover plate of the matching panel first, and then remove the rotating shaft in the second transmission block and the limit second transmission block. To disassemble the limiting plate, it is necessary to turn the handle and turn the second transmission block 90 degrees to align the other notch with the pin, and finally reassemble the above parts one by one. Therefore, the structure of the product is relatively complicated, and the reversing process requires Dismantling more parts will cause more trouble in reversing.
