[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please refer to Figure 1-Figure 5 The utility model provides a technical solution: an elevator shaft frame, including a bottom plate 1 and several frame bodies, the frame body includes a circular frame 2, the four corners of the top of the circular frame 2 are fixedly connected with vertical rods 3, the top and bottom ends of the opposite outer surfaces of two adjacent vertical rods 3 are fixedly connected with cross bars 4, and slide rails 5 are movably arranged between the two left cross bars 4 and between the two right cross bars 4. The surface of the slide rail 5 is provided with a slide groove 17, the top outer surface of the slide rail 5 is provided with a slot 6, the inside of the slot 6 is provided with a sealing plastic bag 7, and the bottom outer surface of the slide rail 5 is provided with a sealing plastic bag 7. The surface is fixedly connected with an insert block 8 that is compatible with the slot 6, and the bottom outer surface of the insert block 8 is fixedly connected with a number of needles 9. Specifically, when splicing the upper and lower slide rails 5, the insert block 8 of the upper slide rail 5 is inserted into the slot 6 at the top of the lower slide rail 5. When the insert block 8 is inserted into the slot 6, the needles 9 pierce the sealing plastic bag 7, and the sealant inside the sealing plastic bag 7 leaks out, and fills the gap between the two slide rails 5, so as to avoid the elevator shaking when the pulley passes through the connection of the slide rail 5 due to the uneven connection when the elevator is in operation.

[0023] In this embodiment, support rods are fixedly connected to the four corners of the top of the base plate 1, and the four support rods are respectively fixedly connected to the four corners of the bottom of the bottom circular frame 2. Four dampers 15 are installed on the top outer surface of the base plate 1, and the top outer surfaces of the four dampers 15 are fixedly connected to a support plate 16.

[0024] In this embodiment, an adjusting screw 10 is rotatably connected between the opposite outer surfaces of the two front vertical rods 3 and the two rear vertical rods 3. The outer surface of the adjusting screw 10 is threadedly connected to a threaded block 11, and the slide rail 5 is fixedly connected to the outer surface of the threaded block 11. Specifically, the threaded block 11 is driven to move by rotating the adjusting screw 10, and the threaded block 11 drives the slide rail 5 to move, so that the upper and lower adjacent slide rails 5 correspond to each other.

[0025] In this embodiment, the outer surface of the adjusting screw 10 is fixedly connected to a rotating sleeve 12, and the outer surface of the rotating sleeve 12 is provided with an anti-slip pad. Specifically, the rotating sleeve 12 facilitates the rotation of the adjusting screw 10, and the anti-slip pad increases the friction between the rotating sleeve 12 and the hand, thereby facilitating the rotation of the adjusting screw 10.

[0026] In this embodiment, the outer surfaces of the front and rear sides of the slide rail 5 are fixedly connected with fixing ears 13 at the top and bottom ends, and the outer surfaces of the fixing ears 13 are provided with connecting holes 14. Bolts 18 are provided inside the connecting holes 14, and nuts are threadedly connected to the outer surfaces of the bolts 18. Specifically, when the upper and lower adjacent ears correspond to each other, the bolts 18 are screwed into the corresponding connecting holes 14, and the upper and lower ears are connected by the bolts 18 and the nuts, thereby splicing the upper and lower slide rails 5.

[0027] In this embodiment, the outer surfaces of the two rear vertical rods 3 are fixedly connected to two sliding rods, and the threaded block 11 is movably sleeved on the outer surfaces of the two sliding rods. The length of the sliding rod is less than the length of the threaded rod at the rotating sleeve 12. Specifically, when the rotating adjusting screw 10 drives the threaded block 11 to move, the threaded block 11 slides on the outer surface of the sliding rod, preventing the threaded block 11 from rotating with the rotation of the adjusting screw 10, and the required space is provided for rotating the adjusting screw 10 by the length of the sliding rod being less than the length of the threaded rod at the rotating sleeve 12.

[0028] Working principle: When the utility model is used, when splicing a single frame body, first align the upper and lower adjacent frame bodies, and adjust the positions of the two adjacent slide rails 5. When adjusting, by rotating the rotating sleeve 12, the rotating sleeve 12 drives the adjusting screw 10 to rotate, the adjusting screw 10 drives the threaded block 11 to move, and the threaded block 11 drives the slide rail 5 to move, so that the upper and lower slide rails 5 are accurately aligned and the adjacent frame bodies are connected. When splicing the upper and lower slide rails 5, insert the insert block 8 of the upper slide rail 5 into the slot 6 at the top of the lower slide rail 5. When the insert block 8 is inserted, the upper slide rail 5 is inserted into the slot 6 at the top of the lower slide rail 5. When the block 8 is inserted into the slot 6, the needle 9 punctures the sealing plastic bag 7, and the sealant inside the sealing plastic bag 7 leaks out and fills the gap between the two slide rails 5. Then the bolt 18 is screwed into the corresponding connection hole 14, and the upper and lower ears are connected by the bolt 18 and the nut, so that the upper and lower slide rails 5 are spliced ​​and the gap at the connection of the two slide rails 5 is filled to avoid the elevator shaking when the pulley passes through the connection of the slide rail 5 due to the uneven connection during operation. After the slide rail 5 is fixed, the adjacent frame body is fixed.

[0029] After the elevator descends, it contacts the top of the support plate 16, which cushions the elevator through the damper 15 and also reduces the vibration generated during startup.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
