[0011] Preferably, the surface of the adjusting bolt is provided with symmetrically distributed threads, and when the adjusting bolt is rotated, the two fixing components move toward or away from each other synchronously.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides an elevator speed governor installation structure that is easy to disassemble and assemble, including a speed governor mechanism 1 composed of a speed governor body 101 and a fixed foot 102 installed at the bottom of the speed governor body 101, a position adjustment mechanism 2 is arranged at the bottom of the fixed foot 102, a positioning mechanism 3 is arranged at the bottom of the position adjustment mechanism 2, a fixing mechanism 4 is arranged inside the position adjustment mechanism 2, and a movable mechanism 5 is arranged on one side of the position adjustment mechanism 2; wherein the position adjustment mechanism 2 includes a limit frame 201, an adjusting bolt 202 and a fixing assembly 203, and the limit frame 201 is slidably connected to the positioning mechanism 3. At the top, the adjusting bolt 202 is rotatably connected to the middle part of the limiting frame 201, and the fixing component 203 is slidably connected to the inside of the limiting frame 201 and is threadedly connected to the surface of the adjusting bolt 202; the fixing mechanism 4 includes a connecting rod 401, a telescopic component 402 and a hinged rod 403, the connecting rod 401 is installed inside the limiting frame 201, the telescopic component 402 is fixedly installed on the top of the connecting rod 401, and the two ends of the telescopic component 402 are respectively connected to the hinged rod 403, and the surface of the adjusting bolt 202 is provided with symmetrically distributed threads. When the adjusting bolt 202 rotates, the two fixing components 203 move synchronously toward or away from each other.

[0032] The speed limiter mechanism 1 is placed inside the limiting frame 201, and the two fixing components 203 can be driven to move synchronously in the opposite direction by rotating the adjusting bolt 202, so that the fixing components 203 enter the middle part of the fixing foot 102, thereby realizing the rapid fixation of the speed limiter mechanism 1, and when the two fixing components 203 move in the opposite direction, the telescopic component 402, which is originally squeezed by the fixing components 203 and is in a compressed state, is extended, and the telescopic component 402 cooperates with the two mutually hinged hinge rods 403 to pull the movable mechanism 5 in the direction close to the speed limiter mechanism 1, thereby realizing the preliminary fixation of the speed limiter mechanism 1.

[0033] like Figure 6 and Figure 7 As shown, the movable mechanism 5 includes a movable plate 501 and a block 502, the block 502 is fixedly installed at the lower end of the movable plate 501, the movable plate 501 is slidably connected to the hinge rod 403, the positioning mechanism 3 includes a connecting plate 301 and a positioning slot 302, the connecting plate 301 is connected to the elevator by bolts, the positioning slot 302 is opened at the top of the connecting plate 301, the movable plate 501 and the block 502 are both located in the positioning slot 302, when the fixed component 203 is not in contact with the movable column 4022, the block 502 is adapted to be engaged with the positioning slot 302, and the movable plate 501 is in pressure contact with the fixed foot 102 and the limit frame 201.

[0034] By cooperating with the provided block 502 and the positioning slot 302, the position of the limit frame 201 can be adjusted, and the adjustment of the limit frame 201 can be synchronized with the position fixation of the speed limiter mechanism 1. By rotating the adjusting bolt 202, the fixing component 203 cancels the compression of the telescopic component 402, and the speed limiter mechanism 1 can be initially fixed by the movable plate 501. At the same time, the position of the limit frame 201 can also be locked by the block 502.

[0035] like Figure 5 and Figure 6 As shown, the telescopic assembly 402 includes a fixed shell 4021, a movable column 4022 and a third spring 4023. The fixed shell 4021 is fixedly connected to the connecting rod 401, the movable column 4022 is slidably connected to the two ends of the fixed shell 4021, and the third spring 4023 is arranged inside the fixed shell 4021 and the two ends are respectively connected to the two movable columns 4022.

[0036] When the two fixed components 203 are close to each other, the two movable columns 4022 can be squeezed close to each other. At this time, under the lever action of the fixed component 203, the movable plate 501 is not in contact with the speed limiter mechanism 1. At this time, the fixed foot 102 can be conveniently inserted into the limiting frame 201. At the same time, the block 502 is not connected with the connecting plate 301, and the position of the limiting frame 201 can be adjusted.

[0037] like Figure 6 As shown, the hinge rod 403 is hinged to the movable column 4022 , the two hinge rods 403 are distributed up and down and hinged in the middle, and one end of the hinge rod 403 away from the movable column 4022 is slidably connected to the movable plate 501 through a hinge block.

[0038] The two hinge rods 403 are scissor-shaped. When the ends of the two hinge rods 403 on the same side move closer to or farther from each other, the movable plate 501 can be driven to move, and the hinge block can slide on the movable plate 501, thereby ensuring the rationality of the structure.

[0039] like Figure 8 and Fig. 9 As shown, the fixing assembly 203 includes a limiting shell 2031, an extrusion plate 2032, a first spring 2033, a second extrusion plate 2034 and a second spring 2035. The limiting shell 2031 is threadedly connected to the adjusting bolt 202. The extrusion plate 2032 elastically slides inside the limiting shell 2031 through the first spring 2033. The second extrusion plate 2034 elastically slides inside the limiting shell 2031 through the second spring 2035. One end of the extrusion plate 2032 is an inclined surface and is adapted to the upper end of the second extrusion plate 2034. The lower end of the second extrusion plate 2034 is in inclined contact with the fixing foot 102.

[0040] The extrusion plate 2032 can be squeezed when the limiting shell 2031 approaches the inner wall of the limiting frame 201, so that the first spring 2033 is compressed. At this time, the extrusion plate 2032 squeezes the first spring 2033 downward through the inclined surface, and the downward movement of the first spring 2033 can further fix the fixed foot 102, which can prevent shaking caused by dimensional errors.

[0041] The working principle and use process of the present invention:

[0042] In practice, firstly, the connecting plate 301 is fixed to the elevator by bolts, then, the speed limiter body 101 is placed inside the limiting frame 201, and then the position of the limiting frame 201 is adjusted. After the adjustment, the adjusting bolt 202 is rotated to drive the two fixing components 203 to move synchronously in opposite directions. During the movement, the two movable columns 4022 first move in opposite directions under the elastic force of the third spring 4023, thereby driving the two hinged rods 403 to open, and then driving the movable plate 501 to move in the direction of the fixed foot 102, so as to achieve the preliminary fixation of the speed limiter mechanism 1. Synchronously, the block 502 is engaged with the positioning slot 302 on the connecting plate 301, so as to achieve the position fixation of the limiting frame 201.

[0043] Then, the fixing assembly 203 continues to move, and the extrusion plate 2032 is gradually squeezed and moved by the inner wall of the limiting frame 201. The movement of the extrusion plate 2032 drives the second extrusion plate 2034 to move downward, so that the fixing foot 102 is squeezed by the second extrusion plate 2034, and the position of the entire speed limiter mechanism 1 is further fixed.
