[0006] Furthermore, the outer side of the installation stop fitting column is a cylindrical structural surface, and the installation clamping connection groove is consistent with the central axis of the installation stop fitting column and is a cylindrical structure.
[0007] Furthermore, a matching guide arc surface is provided at the inner edge of the locking and matching connecting groove.
[0008] Furthermore, the projected shape of the locking and fitting connecting groove is a rectangular notch shape.
[0009] Furthermore, a chamfered structure for convenient installation and assembly is provided at the outer edge of the main body assembly connecting column.
[0010] Beneficial effects of the utility model:
[0011] The utility model can be quickly locked and combined during installation through the locking structure that communicates with the inside and outside, and the outer ends can be associated and matched through the locking connection groove, and there is no need to use fastening bolts for fixation. After being matched by inserting the staggered combination, the limited installation of the pin shaft is achieved by the fastening on the door and window, and there is no need for separate fastening, which makes the operation during the overall installation more convenient. The position of the locking connection groove can be provided with lubricating liquid as needed to ensure that the opening and closing durability during use is stronger, and it can also enable the air inside and outside to circulate and match, ensuring better safety during use.

[0020] like Figures 1 to 7As shown, a safety-type door and window pin shaft includes a cylindrical main assembly connecting column 1, and an integrally formed installation stop fitting column 2 is provided on the right side of the main assembly connecting column 1. The installation stop fitting column 2 is provided with an installation latching connection groove 3, which can be latched and fitted when assembled on the outside and can be fitted together with hinge components. A cylindrical main body stable combination hole 4 that does not completely penetrate the right side of the whole is provided at the center position of the left end face of the main assembly connecting column 1, which can be inserted and assembled with the matching connecting shaft. The outer cylindrical surface of the main assembly connecting column 1 is provided with cylindrical avoidance fitting safety grooves 5 that are evenly distributed on the left and right to ensure that there is more space on the outside and that the lubricating fluid can be fitted with better fluidity. The avoidance fitting safety groove 5 is provided with latching fitting connection grooves 6 that are evenly distributed around the circumference and communicate with the main body stable combination hole 4, which can be quickly assembled and connected with the telescopic latching structure of the internal fitting position. During installation, it can be quickly combined by the locking structure that is connected to the inside and outside. The outer end can be connected and matched through the locking connection groove, and does not need to be fixed with fastening bolts. After being inserted into a staggered combination, the pin shaft is limited and installed through the fastening on the door and window, and no separate fastening is required. The overall installation operation is more convenient. Lubricating liquid can be set at the position of the locking connection groove as needed to ensure that the opening and closing durability during use is stronger, and it can also allow the air inside and outside to circulate and match, ensuring better safety during use.
[0021] Preferably, the outer side of the installation stop fitting column 2 is a cylindrical structural surface, and the installation locking connection groove 3 is the same as the central axis of the installation stop fitting column 2 and is a cylindrical structure, which is more efficient during production and processing, has better structural safety at the outer position, and occupies relatively small space.
[0022] Preferably, a matching guide arc surface is provided at the inner edge of the locking and fitting connection groove 6, so that the inner side can be matched with the locking structure more smoothly and the connection and fitting efficiency during assembly is higher.
[0023] Preferably, the projected shape of the locking and fitting connecting groove 6 is a rectangular notch shape. When fitting, the space of the combination position is larger, and the position can be adjusted as needed to ensure more convenient operation during fitting, while enabling better air circulation and lubricating liquid fitting at the fitting position.
[0024] Preferably, the outer edge of the main body assembly connecting column 1 is provided with a chamfered structure for convenient installation and assembly, which makes the assembly operation more convenient during installation and has a matching guide function.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
