A fixing bolt 3 is provided on the top of the inner cavity of the limiting groove 10. One end of the fixing bolt 3 passes through the limiting seat 9 and the outer sleeve 1 and is plugged into the inner wall of one of the through holes 8. A limiting plate 14 is rotatably provided on the top of the fixing bolt 3, and the limiting plate 14 is plugged into the inner wall of the limiting groove 10.
[0034] The elevator car pull rod provided by the utility model is provided with an outer sleeve 1 and an inner rod 2, and the outer sleeve 1 and the inner rod 2 are retractably arranged, so that during transportation, the utility model can be shortened to a smaller length to save space and improve transportation efficiency, and is convenient for stacking and loading and unloading in transport vehicles, containers or warehouses, thereby reducing transportation costs; due to the space saved, the transport vehicle can carry more elevator components, thereby improving the efficiency and economic benefits of a single transport.
[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0038] Example 1, please refer to Figure 1-Figure 6 , an elevator car pull rod, comprising an outer sleeve 1, an inner rod 2 is inserted and connected in the outer sleeve 1, and a plurality of through holes 8 are opened on the inner rod 2, a limited seat 9 is fixedly installed on the top of the outer sleeve 1, and a limited groove 10 is opened on the top of the limited seat 9, and a fixing bolt 3 is arranged on the top of the inner cavity of the limited groove 10, and one end of the fixing bolt 3 passes through the limited seat 9 and the outer sleeve 1 and is plugged into the inner wall of one of the through holes 8, and a limiting plate 14 is rotatably arranged on the top of the fixing bolt 3, and the limiting plate 14 is plugged into the inner wall of the limiting groove 10. The outer sleeve 1 and the inner rod 2 are provided in the present application, and the outer sleeve 1 and the inner rod 2 are retractable, so that the present application can be shortened to a smaller length during transportation, so as to save space and improve transportation efficiency, and is convenient for stacking and loading and unloading in a transport vehicle, a container or a warehouse, and reduces transportation costs; due to the space saving, the transport vehicle can load more elevator components, improve the efficiency and economic benefits of a single transport, and due to the retractable setting of the present application, it can be adjusted to a suitable length according to actual needs at the elevator installation site.
[0039] Furthermore, a connecting piece is provided between the limit plate 14 and the fixing bolt 3, and the connecting piece is used to realize the connection between the limit plate 14 and the fixing bolt 3, and realize the rotation of the limit plate 14. A gap is left between the bottom of the limit plate 14 and the bottom of the inner cavity of the limit groove 10, so as to facilitate the rotation and erection of the limit plate 14.
[0040] Further, such as Figure 1-Figure 3 As shown, the connecting piece includes a connecting seat 12 fixedly installed on the top of the fixing bolt 3, and a groove that is plugged into the connecting seat 12 is opened on one side of the limiting plate 14 close to the connecting seat 12, and a rotating shaft 13 is inserted and connected to the middle of the connecting seat 12, and both ends of the rotating shaft 13 are fixedly connected to the groove. Through the cooperation of the connecting seat 12, the groove and the rotating shaft 13, the limiting plate 14 and the fixing bolt 3 can be connected together, and the limiting plate 14 can be rotated. When the limiting plate 14 is set horizontally, the limiting plate 14 and the limiting groove 10 cooperate with each other to limit the fixing bolt 3 to prevent the fixing bolt 3 from rotating by itself. When the limiting plate 14 is rotated to the horizontal, the fixing bolt 3 can be driven to rotate by manually rotating the limiting plate 14, thereby facilitating the manual rotation of the fixing bolt 3. A screwdriver opening is set at the end of the fixing bolt 3 away from the limiting plate 14, and the fixing bolt 3 can also be rotated from the bottom end of the fixing bolt 3 through the screwdriver opening using a screwdriver.
[0041] Further, such as Figure 4 As shown, a circular groove 15 with the rotating shaft 13 as the center is opened on the side of the connecting seat 12, and a coil spring 16 located in the circular groove 15 is sleeved on the outer surface of the rotating shaft 13. The two ends of the coil spring 16 are respectively fixedly connected to the rotating shaft 13 and the circular groove 15. The action force of the coil spring 16 can keep the limit plate 14 horizontal, thereby improving the stability of the limit plate 14.
[0042] Further, such as Figure 3 As shown, avoidance grooves 11 are provided on the inner walls on both sides of the limiting groove 10. The setting of the avoidance grooves 11 can avoid interference between the limiting plate 14 and the inner wall of the limiting groove 10 after it is erected, thereby ensuring that the limiting plate 14 can rotate after it is erected.
[0043] The fixing bolt 3 is arranged to pass through the outer sleeve 1, and the opening depth of the limiting groove 10 is much greater than the thickness of the limiting plate 14. This arrangement allows the limiting plate 14 to continue to rotate to a position corresponding to the limiting groove 10 after the fixing bolt 3 passes through the through hole 8, so that the limiting plate 14 can be arranged horizontally and cooperate with the inner wall of the limiting groove 10 to limit the fixing bolt 3.
[0044] Embodiment 2 further optimizes the elevator car pull rod provided in Embodiment 1. Specifically, a limiting member is further provided between the limiting seat 9 and the limiting plate 14. The limiting member is used to limit the limiting plate 14, which can further reduce the situation where the limiting plate 14 rotates on its own.
[0045] Further, such as Figure 3 and Figure 5 As shown, the limit member includes a chamber 17 opened in the limit seat 9 and a slot 20 opened on the side of the limit plate 14. The chamber 17 is slidably connected to the limit rod 18. One end of the limit rod 18 passes through the limit seat 9 and is plugged into the slot 20. The end of the limit rod 18 plugged into the slot 20 is hemispherical, and the slot 20 is also hemispherical. Therefore, when the limit plate 14 is manually rotated, the hemispherical setting can facilitate the separation and connection of the limit rod 18 and the slot 20.
[0046] Further, such as Figure 5 As shown, a spring 19 is disposed in the chamber 17 , and two ends of the spring 19 are fixedly connected to the chamber 17 and the limiting rod 18 respectively. The force of the chamber 17 can push the limiting rod 18 to keep the limiting rod 18 plugged into the slot 20 .
[0047] Embodiment 3 further optimizes the elevator car pull rod provided in Embodiment 1 or 2. Specifically, Figure 1 and Figure 6 As shown, reinforcing plates 6 are fixedly connected to the inner walls on both sides of the outer sleeve 1, and sliding grooves 7 are opened on both side surfaces of the inner rod 2. The reinforcing plates 6 are plugged into the outer surfaces of the sliding grooves 7. The setting of the reinforcing plates 6 can reinforce the outer sleeve 1, and the setting of the sliding grooves 7 is used to avoid the reinforcing plates 6.
[0048] Further, such as Figure 1 and Figure 6 As shown, the inner rod 2 and the outer sleeve 1 are fixedly connected to a mounting base 4 at one end away from each other. The mounting base 4 is provided with a mounting hole 5, and the mounting hole 5 is used to fix the mounting base 4 to the car by bolts to realize the installation of the present application.
[0049] The use process of the elevator car pull rod provided by the utility model is as follows:
[0050] Reference Figure 1 and Figure 6 , Figure 1 For the shortened state of this application, Figure 6 In the extended state, when it is necessary Figure 1 Switch to Figure 6In the state, first, the limit plate 14 is rotated with the rotating shaft 13 as the center to be erected. During the rotation of the limit plate 14, the limit plate 14 squeezes the limit rod 18 through the slot 20 so that the limit rod 18 moves into the chamber 17 and separates from the slot 20. When the limit plate 14 is rotated to be erected, the limit plate 14 is rotated to drive the fixing bolt 3 to rotate, so that the fixing bolt 3 is separated from the corresponding through hole 8, and then the outer sleeve 1 is pulled to make the inner rod 2 extend, and then the limit plate 14 is rotated in the opposite direction so that the limit plate 14 brings The movable fixing bolt 3 is rotated, and the fixing bolt 3 is separated from the corresponding through hole 8 to fix the inner rod 2 and the outer sleeve 1, and then the limiting plate 14 is loosened, and the force of the circular groove 15 makes the limiting plate 14 tend to be horizontal, and then the limiting plate 14 is pressed so that the limiting plate 14 squeezes the limiting rod 18. When the limiting rod 18 is aligned with the slot 20, the force of the spring 19 pushes the limiting rod 18 to be inserted into the slot 20. At this time, the limiting plate 14 is horizontally inserted into the limiting groove 10 to limit the fixing bolt 3;
[0051] When needed by Figure 1 Switch to Figure 6 When the inner rod 2 is in the closed state, the above operation is repeated, and the operation of pulling the outer sleeve 1 to extend the inner rod 2 is changed to pushing the inner rod 2 into the outer sleeve 1 to retract the inner rod 2 into the outer sleeve 1.
