[0025] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Next, the embodiments of the present invention will be further described in detail with reference to the drawings as follows:

[0027] A quick - detachable handle lock, as shown in Figure 1 and Figure 3 , comprising a lock box 1, a quick - installation handle 2 that can rotate relative to the lock box 1, and a transmission rod 3. The transmission rod 3 slides as the quick - installation handle 2 rotates, as shown in Figure 4 and Figure 5As shown in the figure, a rotating gear 4 is installed inside the lock box 1, and two sets of elastic locking mechanisms 5 are oppositely installed on the outer periphery of the rotating gear 4. A straight tooth 6 meshing with the rotating gear 4 is provided in the middle of the transmission rod 3. Through holes 8 are respectively provided at both ends of the transmission rod 3, and through holes 8 are provided in the guide grooves 7. When the handle is not installed, the fixing screw plate assembly can be adjusted to rotate by inserting a hexagonal wrench through the through holes 8, so that the lock box is installed on the door and window profiles. The through holes 8 can also be used to insert a hexagonal wrench against the limit block after the handle is installed, so that the first spring is compressed. At this time, when the handle is rotated in the reverse direction, the handle can be disassembled. Accommodation grooves 9 are respectively provided at both ends of the lock box 1, and a limit block 10 cooperating with the guide groove 7 is movably installed in one of the accommodation grooves 9. A first spring 11 is installed between the limit block 10 and the inner wall of the accommodation groove 9. The limit block 10 abuts against the step of the transmission rod 3 before installation, and a bump cooperating with the limit block 10 is provided on the step of the transmission rod 3. The quick-install handle 2 includes a quick-install piece 12, and the quick-install piece 12 rotates as the quick-install handle 2 rotates. A crescent groove 13 is provided on one side of the lock box 1 where the quick-install handle 2 is located. The quick-install piece 12 passes through the crescent groove 13 and then rotates, so that the quick-install handle 2 cooperates with the lock box 1. Fixed screw plate assemblies 14 are respectively installed at both ends inside the lock box 1. The fixed screw plate assembly 14 includes a rotating screw 15 corresponding to the through hole 8 and a rotating screw piece 16 threadedly connected to the rotating screw 15. A second spring 17 is limitedly penetrated between the rotating screw 15 and the rotating screw piece 16. The lock box 1 is provided with a slot 18 corresponding to the rotating screw piece 16.

[0028] As Figure 2 shown, before the quick-install handle 2 is installed, the dust cover 34 can be inserted into the gear hole of the lock box 1, which can prevent dust from entering the lock box during transportation and effectively improve the service life of the lock box.

[0029] When the present invention is in use, first install the lock box 1 in the groove of the door and window profiles, and then through the fixed screw plate assembly 14, rotate the rotating screw 15 so that the rotating screw piece 16 penetrates through the slot 18 and is clamped in the slot of the profiles to realize the fixation of the lock box 1. When installing the quick-install handle 2, as Figure 6 shown, first insert the handle into the lock box at -45° relative to the horizontal plane. The quick-install piece 12 passes through the crescent groove 13. By rotating the handle, the handle is cooperatively locked with the lock box. During the rotation process, the handle drives the rotating gear 4 to rotate. The rotating gear 4 drives the transmission rod 3 through the straight tooth 6, so that the transmission rod 3 slides as the quick-install handle 2 rotates. When the transmission rod 3 slides to the horizontal position of the handle, as Figure 7 shown, the limit block 10 leaves the step of the transmission rod 3 and slides and then penetrates into the guide groove 7 through the first spring 11. At this time, one end of the limit block 10 penetrates into the guide groove 7 and cannot slide in the reverse direction, and the handle is misaligned between the quick-install piece and the crescent groove, realizing the quick installation of the handle. As Figure 8 described, when the handle is in use, the limit block 10 slides axially along the guide groove 7.

[0030] When the quick - release handle 2 is in a horizontal state and the handle needs to be disassembled, a hex wrench is inserted into the corresponding through - hole 8 to press against the limit block 10, compressing the first spring 11. At this time, the handle is rotated in the reverse direction, and the quick - release piece 12 is taken out along the crescent - shaped groove 13, and then the handle can be disassembled.

[0031] The lock box 1 is provided with step eaves 19 covering both side edges of the transmission rod 3. The lock box 1 includes a main housing 20 and a sub - housing 21 that are fitted together. The main housing 20 is provided with several groups of positioning posts 22, and the sub - housing 21 is respectively provided with positioning holes 23 corresponding to the several groups of positioning posts 22. Through the cooperation of the positioning posts 22 and the positioning holes 23, the installation of the main housing 20 and the sub - housing 21 can be made quick and simple.

[0032] At both ends of the lock box 1 of the present invention, accommodation grooves 9 are respectively opened. At both ends of the transmission rod 3, guide grooves 7 are respectively opened. And a limit block 10 that cooperates with the guide groove 7 is installed in one of the accommodation grooves 9. By installing the limit block 10 in different accommodation grooves 9, the rotation amplitude of the handle is effectively limited. The lock box 1 is provided with a crescent - shaped groove 13, and the quick - release handle 2 is provided with a quick - release piece 12. Through the cooperation of the quick - release piece 12 and the crescent - shaped groove 13, the quick installation of the handle is realized. There is no need to drill holes in the profile to fix the handle, and the handle can be realized without a base, reducing damage to the profile. When disassembling, only a hex wrench is inserted into the corresponding through - hole 8 to press against the limit block 10, compressing the first spring 11. At this time, the handle is rotated in the reverse direction, and the quick - release piece 12 is taken out along the crescent - shaped groove 13, and then the handle can be disassembled. The present invention can quickly assemble the handle and can separate and transport the handle during transportation, improving the convenience of handle transportation.

[0033] The quick - release handle 2 includes a grip 24, a handle head 25 that rotates with the rotation of the grip 24, and a lock core 26. The lock core 26 has a stepped square - shaft structure. One end of it penetrates through the quick - release piece 12 and is connected with the handle head 25 in a matching manner, and the other end passes through the rotating gear 4. A limit seat 27 is sleeved outside the handle head 25 on the grip 24. The lock core 26, the quick - release piece 12, the handle head 25, and the grip 24 are sequentially connected by fixing screws 28.

[0034] The limit block 10 has a multi - stepped structure, which includes a first step 29 and a second step 30. The first step 29 is limited and movable in the accommodation groove 9, and the second step 30 abuts against the guide groove 7. Through the first step 29, the limit block 10 can be prevented from falling out of the accommodation groove 9, and through the second step 30, the limit block 10 can abut against the guide groove 7 and reduce the friction between the groove wall of the guide groove 7 and the limit block 10.

[0035] The elastic locking mechanism 5 includes a ball 31 and a third spring 32. One end of the third spring 32 abuts against the lock box 1, and the other end supports the ball 31 to abut against the rotating gear 4.

[0036] The outer wall of the lock box 1 is provided with a direction mark 33, and the direction mark 33 is used to distinguish the left and right opening directions of the lock box.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
