[0026] Furthermore, the traction and dispersion mechanism 5 includes a dispersion base 501, which is fixedly connected to one side surface of the bottom plate mounting mechanism 4, and the inner wall surface of the dispersion base 501 is rotatably connected to the dispersion block 502, and the inner wall surface of the dispersion block 502 is fitted with a mounting male part 503, and one side surface of the mounting male part 503 is fitted with a mounting female part 504, and one side surface of the mounting female part 504 is fixedly connected with a mounting spring 505, and one side surface of the mounting female part 504 is fixedly connected with a release rod 506, and the side surface of the mounting male part 503 away from the dispersion block 502 is fixedly connected with a dispersion spring 507, and one side surface of the mounting male part 503 is fitted with a pop-up spring 508 adapted to the inner wall of the dispersion block 502. Through the setting of the traction and dispersion mechanism 5, when in use, the dispersion base 501 is fixed to the bottom plate mounting mechanism 4, and the dispersion block 502 can be The dispersion base 501 rotates inside, the installation male part 503 fits with the installation female part 504, the installation spring 505 abuts the installation female part 504, the dispersion spring 507 connects the installation male part 503 and the dispersion base 501, and the pop-up spring 508 fits with the dispersion block 502 and the installation male part 503; during traction, the dispersion spring 507 deforms to disperse the force, and during disassembly, the release rod 506 is pushed to make the installation female part 504 compress the installation spring 505 and separate from the installation male part 503, and the pop-up spring 508 pushes the dispersion block 502 to rotate and unlock, and the dispersion spring 507 connects the installation male part 503 and the dispersion base 501. When the traction device is connected to the installation male part 503, the traction force can be dispersed by the dispersion spring 507 through deformation, avoiding single-point force overload. During disassembly, the release rod 506 is pushed to cooperate with the pop-up spring 508 to achieve quick unlocking, thereby ensuring the safety and convenience of the traction connection.

[0027] Furthermore, two groups of module fixing mechanisms 3 are symmetrically arranged around the top central axis of the car 1. The car 1 is fixedly connected to the surface of one side of the beam 2 through the module fixing mechanism 3. The design of setting two groups of module fixing mechanisms 3 can make the connection between the car 1 and the beam 2 evenly stressed during use, thereby avoiding structural deviation caused by unilateral stress and enhancing the stability and reliability of the overall connection.

[0028] Furthermore, two groups of fixed mother parts 302 and fixed springs 303 are symmetrically arranged around the central axis of one side surface of the fixed male part 301, and two groups of linkage plates 305 are symmetrically arranged around the central axis of the linkage disk 306, and form an eccentric connecting rod structure with the linkage disk 306.

[0029] Furthermore, the driving screw 402 forms a synchronous transmission structure with the driven screw 404 through the synchronous belt 403, and the support plate 401, the driving slider 405 and the telescopic plate 406 are symmetrically arranged in two groups with the central axis of the beam 2. The synchronous transmission structure is formed by the driving screw 402, and the support plate 401, the driving slider 405 and the telescopic plate 406 are arranged in two groups. When in use, the telescopic plates 406 on both sides can be synchronously raised and lowered to ensure that the heights of the two sides of the bottom end of the car 1 are consistent, avoiding installation errors caused by height deviations, and improving the accuracy of the bottom plate installation.

Through the design of the left and right fixed jaws 407 and the front and rear fixed jaws 413, when in use, the "L"-shaped jaws can form an embracing clamp on the car 1 in the horizontal and vertical directions. Combined with the sliding adjustment function of the slide rail, it can not only adapt to the installation requirements of cars of different sizes, but also ensure the stability of the clamping.

[0031] Furthermore, the dispersion base 501 is fixedly connected to the support plate 401 and one side surface of the front and rear fixed clamps 413. The traction dispersion mechanism 5 is symmetrically arranged with four groups around the central axis of the car 1. Through the dispersion base 501, the traction dispersion mechanism 5 is designed to have four groups. When in use, the four groups of dispersion mechanisms can evenly distribute the traction force and disperse the concentrated force to the four sides of the car 1, effectively avoiding structural damage caused by excessive local force and improving the safety and reliability of the traction connection.

[0032] Furthermore, a release column is fixedly connected to the surface of one side of the mounting member 503, and the dispersion block 502 is fixedly connected to the surface of one side of the mounting member 503 through the pop-up spring 508 and the release column. Through the design of the mounting member 503, when in use, the release column can accurately transmit the thrust of the release rod 506, and cooperate with the elastic action of the pop-up spring 508 to ensure that the dispersion block 502 is quickly rotated into place when unlocked, thereby improving the disassembly efficiency and operational convenience of the traction dispersion mechanism 5.

[0033] Working principle: When the equipment starts to be installed, first fix the crossbeam 2 to the top of the car 1, and then install the fixed male part 301 on the side of the crossbeam 2 in the module fixing mechanism 3, so that the fixed female part 302 fits the fixed male part 301. At this time, the fixed spring 303 is in a natural state and abuts the fixed plate 304. Pressure is applied to the fixed plate 304 to make it move toward the fixed male part 301, compressing the fixed spring 303 to accumulate elastic potential energy. When the two sets of fixed female parts 302 move with the fixed plate 304 beyond the critical point, the fixed spring 303 releases the elastic potential energy, pushing the fixed plate 304 to engage with the fixed male part 301 to limit the position, and the fixed spring 303 is completed. To complete the installation of the module fixing mechanism 3, during disassembly, use a drill to tighten the release bolt 307, driving the linkage disk 306 to rotate clockwise. The linkage disk 306 drives the two sets of linkage plates 305 to rotate synchronously through the eccentric structure, pushing the fixed female component 302 away from the fixed male component 301, compressing the fixing spring 303 and releasing the limit on the fixing plate 304, realizing the separation of the fixing plate 304 and the fixed male component 301, completing the rapid disassembly of the module fixing mechanism 3. This process uses the elastic potential energy of the spring and the mechanical transmission of the linkage connecting rod to achieve automatic engagement during installation and mechanical unlocking during disassembly, ensuring the rapid assembly and disassembly efficiency of the modular components. Then install the bottom plate mounting mechanism 4, fix the support plate 401 to the outer surface of the car 1 through the fixing plate 304, insert a drill into the hexagonal hole at the bottom end of the driving screw 402, drive the driving screw 402 to rotate, and drive the driven screw 404 to rotate synchronously through the synchronous belt 403. The rotation of the driving screw 402 and the driven screw 404 causes the driving slider 405 to move along the outer thread of the screw, pushing the telescopic plate 406 to telescope and slide on the inner wall of the support plate 401, forming an adjustable telescopic structure. The overall height of the support plate 401 and the telescopic plate 406 can be accurately adjusted according to the actual height of the car 1 to meet the size requirements of different installation scenarios. After that, the left and right fixed jaws 407 are attached to the sides of the telescopic plate 406. Slide along the left and right fixed rails 408 to the appropriate position, tighten the left and right fixed screws 409 and lock them through the left and right fixed handles 410. At the same time, the front and rear positioning blocks 411 connect the left and right fixed rails 408 and the front and rear fixed rails 412, slide the front and rear fixed claws 413 along the front and rear fixed rails 412 to the corresponding positions, and tighten and fix them through the front and rear fixed screws 414 and the front and rear fixed handles 415 to form a surrounding clamping structure for the car 1, achieving a stable installation of the bottom end from the left and right and front and rear directions, ensuring the rigid connection between the car 1 and the base plate mechanism. This installation process achieves highly adaptive adjustment and multi-directional fixation through the cooperation of screw transmission and rail positioning, taking into account both installation flexibility and structural stability; When the traction device is connected to the mounting member 503, the dispersion spring 507 disperses the traction force through deformation to avoid single-point force overload; when disassembling, push the release rod 506 to make the mounting member 504 compress the mounting spring 505 and separate from the mounting member 503. At the same time, the pop-up spring 508 pushes the dispersion block 502 to rotate, realizing quick release of the connection; At this point, the installation process of the modular rapid assembly passenger elevator car frame structure is completed. The entire installation process is carried out through the sequential assembly of the module fixing mechanism 3, the base plate mounting mechanism 4 and the traction dispersion mechanism 5, and the use of screw transmission, spring abutment and connecting rod linkage structures to achieve rapid positioning, fixation and force transmission of each component, meeting the high efficiency and structural stability requirements of modular installation.
