[0055] The lock body assembly 10 is inserted into the lock body mounting hole 211A of the fan body 2. The lock body assembly 10 is provided with a transmission hole 111, a pre-positioning hole 112 and a fastening hole 113. The lock body assembly is provided with a lock body mounting surface in contact with the lock body mounting hole 211A. The handle assembly includes a handle 20 and a mounting base 30, wherein the mounting base 30 includes a first mounting base 31 and a second mounting base 32. The first mounting base 31 is provided on the first side surface 221 for mounting the first handle 201; the second mounting base 32 is provided on the second side surface 222 for mounting the second handle 202; wherein the first mounting base 31 is provided with a first pre-positioning member 311 and a first fastener 312, and the second A second pre-positioning member 321 and a second fastener 322 are provided on the mounting base 32; the handle 20 includes a first handle 201 and a second handle 202, the first handle 201 is provided on the first side surface 221 of the fan body 2, and the second handle 202 is provided on the second side surface 222 of the fan body 2, the first handle 201 and the second handle 202 are respectively inserted into the transmission hole 111 for transmission connection with the lock body assembly 10; the first pre-positioning member 311 and the second pre-positioning member 321 are respectively inserted into the pre-positioning hole 112 for pre-positioning the first mounting base 31 and the second mounting base 32; the first fastener 312 and the second fastener 322 are respectively inserted into the fastening hole 113 and fixedly connected.

[0056] After the first fastener 312 and the second fastener 322 are respectively inserted into the fastening holes and fixedly connected, the mounting base 30 and the lock body assembly 10 are relatively fixed to limit the relative displacement of the mounting base 30 and the lock body assembly 10 along the fan body 2. The first mounting base 31 abuts the first side surface 221, and the second mounting base 32 abuts the second side surface 222 to limit the displacement of the mounting base 30 along the fan body 2. The lock body mounting surface abuts the lock body mounting hole 211A of the fan body 2 to limit the displacement of the lock body assembly 10 along the fan body 2, forming an installation and fixing structure in which the lock body assembly 10, the handle assembly and the fan body 2 are mutually limited.

[0057] This solution can achieve the lock body mounting surface of the lock body assembly 10 abutting against the fan body 2, and realize the positioning of the first handle 201 and the second handle 202 on the fan body 2 through the mutual cooperation and limitation of the first mounting base 31, the second mounting base 32 and the lock body assembly 10. The first mounting base 31, the second mounting base 32 and the fan body 2, the lock body assembly 10 and the fan body 2, the first mounting base 31, the second mounting base 32 and the lock body assembly 10 are mutually related and mutually limited to form a limited positioning integrated structure. The limited integrated structure of this solution is convenient to install, efficient, firm and stable, and the fan profile 21 has strong compatibility, which can save costs, improve the overall aesthetics of doors and windows, and provide a good operating experience.

[0058] See also Figure 5-6 The first pre-positioning member 311 and the second pre-positioning member 321 have the same shape and structure and are opened facing each other. The outer diameter of the pre-positioning hole 112 is consistent with the outer diameters of the first pre-positioning member 311 and the second pre-positioning member 321. Specifically, the first pre-positioning member 311 and the second pre-positioning member 321 are both anisotropic positioning columns, preferably elliptical positioning columns, so that the pre-positioning of the mounting base can be achieved by adapting the pre-positioning member and the pre-positioning hole. The first fastener 312 is a stud with an external thread, and the second fastener 322 is a screw sleeve with an internal thread. The stud is threadedly connected in the screw sleeve to position the first mounting base 31, the second mounting base 32 and the lock body assembly 10.

[0059] The first pre-positioning member 311 and the second pre-positioning member 321 can be used to pre-position the first mounting base 31 and the second mounting base 32. During the installation process, the first pre-positioning member 311 and the second pre-positioning member 321 are respectively inserted into the pre-positioning hole 112 from the first side surface 221 and the second side surface 222 to achieve pre-positioning between the lock body assembly 10, the first mounting base 31 and the second mounting base 32. At this time, the second fastener 322 is inserted into the fastening hole 113, and the first fastener 312 is inserted into the second fastener 322. The studs are tightened to achieve stable positioning between the first mounting base 31, the second mounting base 32 and the lock body assembly 10.

[0060] Further, the first pre-positioning member 311 and the first mounting base 31 are an integrally formed structure, and the second pre-positioning member 321 and the second mounting base 32 are an integrally formed structure. The first mounting base 31 is provided with a fastening installation hole 314 for inserting the first fastener 312, and the second fastener 322 and the second mounting base 32 are an integrally formed structure. The first pre-positioning member 311 and the fastening installation hole 314 are integrally formed on the first mounting base 31, which facilitates the molding of the first mounting base 31, and the second pre-positioning member 321 and the second fastener 322 are integrally formed on the second mounting base 32, which facilitates the molding of the second mounting base 32.

[0061] See also Figure 4 The lock assembly 10 includes a body 11 and a lock positioning member 12. The body 11 is located between the first side surface 221 and the second side surface 222.

When the lock body adjustment member 122A is rotated, since the adjustable mounting surface 1221A abuts against the first inner wall 2111A, the distance between the first fixed mounting surface 1212A of the first lock body mounting plate 121A and the first inner wall 2111A can be adjusted. When the first fixed mounting surface 1212A is adjusted to abut against the first inner wall 2111A, the limit between the lock body assembly and the fan body is most stable. The arrangement of the lock body adjustment member 122A can make the connection between the lock body assembly and the fan body adjustable, which can avoid errors during the installation process as much as possible and improve the installation stability of the lock.

When adjusting the lock body adjusting member 122A, a force is applied to the first lock body mounting plate 121A so that the first lock body mounting plate 121A abuts against the first inner wall 2111A. At the same time, the main body 11 drives the mounting base 30 to abut against the other side of the fan profile 21.

[0068] The fan substrate 22 in this solution is a glass substrate, the fan profile 21 is an aluminum profile or an alloy profile extending along the thickness direction of the glass substrate, and the first mounting base 31 and the second mounting base 32 are respectively arranged on the first side 221 and the second side 222 of the fan substrate 22.
