DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Embodiment 1

[0019] As Figures 1 to 4 shown, a door handle mounting structure proposed by the present utility model includes a door body 1 and a protective seat 202; an installation plate 101 is provided on the door body 1, a lock body is provided inside the installation plate 101 and within the door body 1, a lock core rotating shaft 102 is provided on the lock body, and the end of the lock core rotating shaft 102 extends outside the installation plate 101 and is detachably installed with an installation sleeve 2. One end of the installation sleeve 2 is installed with a rotating rod 201; the protective seat 202 is installed on the installation sleeve 2 and at the end far from the door body 1, and a rotating seat 203 is provided at the end of the protective seat 202 close to the door body 1, and the rotating seat 203 is movably connected to the door body 1.

[0020] Furthermore, a bolt 4 is provided between the installation sleeve 2 and the lock core rotating shaft 102, a jack adapted to the bolt 4 is provided on the side wall of the installation sleeve 2, and a threaded groove adapted to the bolt 4 is provided on the lock core rotating shaft 102. Facilitate the disassembly and assembly of the installation sleeve 2 and the lock core rotating shaft 102.

[0021] Even further, a limiting component is provided on the inner wall of the installation sleeve 2, and the limiting component includes an elastic member 3 and a convex block 301; the elastic member 3 is installed on the inner wall of the installation sleeve 2, and the elastic member 3 is composed of a telescopic rod and a spring sleeved outside the telescopic rod; the convex block 301 is installed on the elastic member 3, and the convex block 301 abuts against the lock core rotating shaft 102 through the adjustment of the elastic member 3, and an abutting groove 103 adapted to the convex block 301 is provided on the lock core rotating shaft 102.

[0022] Furthermore, the connection methods between the installation sleeve 2 and the rotating rod 201 and the protective seat 202 are both welded connections, avoiding rainwater leakage at the connection points and causing rust on the lock body inside the installation plate 101 or the lock core rotating shaft 102.

[0023] In this embodiment, the lock core rotating shaft 102 is aligned and inserted into the interior of the mounting sleeve 2 and slightly rotated and adjusted so that the convex block 301 abuts against the abutting groove 103. At this time, the elastic member 3 is compressed. Under the elastic force of the elastic member 3, the connection stability between the lifting convex block 301 and the lock core rotating shaft 102 is improved, so that the lock core rotating shaft 102 and the mounting sleeve 2 are initially limited, and the jack on the mounting sleeve 2 corresponds to the threaded groove on the lock core rotating shaft 102. At this time, the bolt 4 is inserted into the jack and then threadedly connected to the threaded groove to fixedly install the mounting sleeve 2 and the lock core rotating shaft 102. At this time, the rotating seat 203 on the protective seat 202 contacts the door body 1. Hold the rotating rod 201 and rotate it, and the opening and closing of the door body 1 can be adjusted through the lock core rotating shaft 102. When the rotating rod 201 rotates, the rotating seat 203 and the door body 1 can be driven to rotate through the mounting sleeve 2 and the protective seat 202. Through the setting of the protective seat 202, the lock core rotating shaft 102 and the mounting plate 101 can also be protected from external damage and the service life can be extended; when the rotating rod 201 is damaged, the bolt 4 is rotated and removed, and then hold the rotating rod 201 and pull the mounting sleeve 2 away from the lock core rotating shaft 102, so that the elastic member 3 is squeezed, and at the same time the convex block 301 slides along the abutting groove 103 until the convex block 301 is separated from the abutting groove 103. At this time, the rotating rod 201 loses its restriction on the lock core rotating shaft 102, and the rotating rod 201 can be removed for replacement, which is convenient and fast.

[0024] Embodiment 2

[0025] As Figure 2 shown, a door handle mounting structure proposed by the present utility model, compared with Embodiment 1, has an annular rail 5 provided on the inner wall of the rotating rod 201 and near the rotating seat 203, and a shielding assembly is movably provided on the annular rail 5 for shielding rainwater infiltrating from the connection between the protective seat 202 and the door body 1.

[0026] Furthermore, the shielding assembly includes a first shielding seat 501, a connecting seat 503 and a counterweight 504; one end of the first shielding seat 501 is provided with a leak-proof pad, and the leak-proof pad abuts against the door body 1 to prevent rainwater from flowing along the door body 1 into the connection between the mounting plate 101 and the door body 1 and causing rust of the lock body. The other end of the first shielding seat 501 is provided with a second shielding seat 502 for shielding and guiding the infiltrated rainwater to prevent the rainwater from flowing to the connection between the lock core rotating shaft 102 and the mounting plate 101 and causing rust. The first shielding seat 501 is V-shaped; there are three groups of connecting seats 503. One end of the connecting seat 503 is connected to the first shielding seat 501, and the other end of the connecting seat 503 is slidably connected to the annular rail 5. The connecting seat 503 is T-shaped to prevent the connecting seat 503 from detaching from the annular rail 5; there are two groups of counterweights 504, and the two groups of counterweights 504 are symmetrically installed at the bottom end of the first shielding seat 501.

[0027] In this embodiment, the lock core rotating shaft 102 is aligned and inserted into the inside of the mounting sleeve 2 and slightly rotated for debugging. During the debugging process, under the action of the counterweight 504, the first shielding seat 501 is adjusted to rotate along the annular rail 5 through the connecting seat 503. Furthermore, the top end of the second shielding seat 502 is always located above the mounting plate 101. When the limiting component is connected to the lock core rotating shaft 102, at the same time, the leak-proof pad on the first shielding seat 501 is pressed against the door body 1, and at the same time, the rotating seat 203 on the protective seat 202 contacts the door body 1. Then, the mounting sleeve 2 and the lock core rotating shaft 102 can be fixedly connected by bolts 4. The setting of the first shielding seat 501 facilitates guiding the rainwater seeping into the connection between the protective seat 202 and the door body 1 downward, preventing it from entering the connection between the mounting plate 101 and the door body 1 and causing interference, thereby avoiding rusting of the internal lock body and extending the service life.

[0028] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
