DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a forklift door hinge installation structure, including an intermediate hinge plate 1, a fixing plate 2 is hingedly connected to the side end of the intermediate hinge plate 1, a forklift door 4 is arranged on the side end of the fixing plate 2, a plurality of sockets 201 are opened on the side end of the fixing plate 2, a plurality of installation grooves 203 are opened on the side end of the fixing plate 2, a side groove 205 is opened on the side end of each installation groove 203, a circular groove 204 is opened on the top of each installation groove 203, a fixing mechanism for fixing the forklift door 4 is arranged inside each installation groove 203, through the setting of the fixing mechanism, when the forklift door 4 needs to be replaced or overhauled, the forklift door 4 can be easily disassembled at any time without tools, thereby avoiding limitations on the replacement or overhaul of the forklift door 4 under different circumstances.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, each fixing mechanism includes an insertion rod 3, each insertion rod 3 is respectively inserted in each installation groove 203, the outer end of each insertion rod 3 is fixedly connected to a rectangular plate 301, the outer end of each insertion rod 3 is sleeved with a spring 1 302, the top end of each insertion rod 3 is inserted into each circular groove 204, which can limit the position of the insertion rod 3, facilitate the contraction and rebound of the spring 1 302, and improve the stability of the upward movement of the rectangular plate 301, the bottom end of each insertion rod 3 is inserted into the socket 201, the side end of each rectangular plate 301 is fixedly connected to a stretching rod 303, each stretching rod 303 is respectively located in each side groove 205, a pull plate 304 is fixedly connected between the side ends of two adjacent stretching rods 303, and a plurality of insertion blocks 401 are fixedly connected to the side end of the forklift door 4, and a socket 402 is provided at the top of each insertion block 401, and each socket 402 is adapted to each insertion rod 3.

[0023] In practice, by pulling the pull plate 304 upward, each extension rod 303 and each rectangular plate 301 are driven to move upward, and each rectangular plate 301 can drive each insertion rod 3 to move upward. When each insertion rod 3 is no longer limited in the socket 201, most of the top of each insertion rod 3 will enter the circular groove 204. At this time, each spring 302 will be squeezed by each rectangular plate 301 and contracted. At this time, by aligning each insertion block 401 at the side end of the forklift door 4 with each socket 201 and inserting it, the socket 4 02 automatically aligns the position of each insertion rod 3. After the pull plate 304 is released, each spring 302 pushes against each rectangular plate 301 to drive each insertion rod 3 to move downward. At this time, each insertion rod 3 can be inserted into the insertion hole 402 at the top of each insertion block 401 respectively. At this time, the insertion block 401 can be fixed to the side end of the fixed plate 2, thereby realizing the fixation and installation of the forklift door 4. Through the same operation method as mentioned above, the insertion rod 3 can be easily moved out of the insertion hole 402, thereby facilitating the disassembly of the insertion block 401 and the forklift door 4.

[0024] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the side end of the forklift door 4 is fixedly connected with a hollow rod 5, the inner side end of the hollow rod 5 is provided with a circular plate 501, the side end of the circular plate 501 is fixedly connected with a round rod 502, the outer end of the round rod 502 is sleeved with a spring 2 503, the side end of the round rod 502 is fixedly connected with a limiting plate 504, the side end of the limiting plate 504 is fixedly connected with a pull rod 505, the side end of the fixed plate 2 is provided with a limiting groove 202, the limiting groove 202 is adapted to the limiting plate 504, in order to further fix the forklift door 4, when the plug block 401 is inserted into the socket 201, the limiting plate 504 and the hollow rod 5 are also correspondingly The second spring 503 is inserted into the limit groove 202. At this time, by pulling the pull rod 505, the limit plate 504 is driven to pass through the limit groove 202 and be located at the side end of the fixed plate 2. At this time, the circular plate 501 will press the spring 2 503 to shrink. At this time, when the limit plate 504 is located at the side end of the fixed plate 2, by rotating the limit plate 504, the direction of the limit plate 504 is inconsistent with the direction in which the limit groove 202 is opened. At this time, after the limit plate 504 is released, the spring 2 503 rebounds against the circular plate 501, so that the limit plate 504 is limited and pressed against the side end of the fixed plate 2, thereby further fixing the forklift door 4.

[0025] Working principle: by pulling the pull plate 304 upward, each extension rod 303 and each rectangular plate 301 are driven to move upward, and at this time each rectangular plate 301 can drive each insertion rod 3 to move upward, when each insertion rod 3 is no longer limited in the socket 201, most of the top of each insertion rod 3 will enter the circular groove 204, and at this time each spring 1 302 will be squeezed by each rectangular plate 301 and contracted. At this time, by aligning each plug block 401 at the side end of the forklift door 4 with each socket 201 and inserting it, the socket 402 automatically aligns with the position of each insertion rod 3, and after releasing the pull plate 304, each spring 1 302 presses against Each rectangular plate 301 drives each insertion rod 3 to move downward, and then each insertion rod 3 can be respectively inserted into the insertion hole 402 at the top of each insertion block 401. At this time, the insertion block 401 can be fixed to the side end of the fixing plate 2, thereby realizing the fixation and installation of the forklift door 4. Through the same operation method as mentioned above, it is convenient to move the insertion rod 3 out of the insertion hole 402, thereby facilitating the disassembly of the insertion block 401 and the forklift door 4. Therefore, when the forklift door 4 needs to be replaced or overhauled, the forklift door 4 can be easily disassembled at any time without tools, avoiding limitations on the replacement or overhaul of the forklift door 4 under different circumstances.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
