Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to an adjustable elevator guide rail. Background Art

[0002] The guide rail is an elevator component consisting of a steel rail and a connecting plate, and is divided into a car guide rail and a counterweight guide rail. The cross-sectional shape is divided into three types: T-shaped, L-shaped, and hollow. While serving as a guide, the guide rail also bears the impact force of the car, the elevator during braking, and the impact force of the safety clamp during emergency braking.

[0003] However, the problem that the existing elevator guide rails are inconvenient to adjust during installation has not been solved, so that the distance between the elevator guide rails and the wall cannot be adjusted when they are installed in conjunction with the wall, so that the guide rails can only be at a fixed distance from the wall, which is relatively rigid and has poor applicability. Therefore, we propose an adjustable elevator guide rail. Utility Model Content

[0004] In view of the above problems, the utility model provides an adjustable elevator guide rail, which has an adjustment effect to prevent the inconvenience of adjusting the distance between the elevator and the wall when installing it on the wall, resulting in poor applicability. At the same time, it has a positioning effect to prevent the poor positioning effect after the adjustment is completed, which will affect the stability of the elevator guide rail and pose certain safety hazards.

[0005] The technical solution of the utility model is: an adjustable elevator guide rail, comprising an elevator guide rail body, a first mounting plate is provided below the elevator guide rail body, connecting plates are fixedly connected to both sides of the elevator guide rail body and the first mounting plate, an extension plate is fixedly connected to the side of the lower connecting plate, a second mounting plate is provided on the side of the upper connecting plate and the lower connecting plate, a limiting groove is provided on the surface of the connecting plate, a first positioning bolt threadedly connected to the second mounting plate is inserted in the limiting groove, and a positioning nut is threadedly connected to the end of the first positioning bolt away from the second mounting plate.

[0006] In a further technical solution, mounting blocks are fixedly connected to both sides of the second mounting plate, the mounting blocks are distributed in pairs, and second positioning bolts are threadedly connected to the surfaces of the mounting blocks.

[0007] In a further technical solution, a plurality of evenly distributed positioning holes are provided on a surface of one side of the connecting plate away from the elevator guide rail body and the first mounting plate.

[0008] In a further technical solution, the second positioning bolt is located in one of the positioning holes, and the second positioning bolt is used to cooperate with the positioning hole to improve the supporting effect of the second mounting plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. The second mounting plate, the limiting groove, and the first positioning bolt cooperate with each other, so that the elevator guide rail body can be adjusted when it is adapted to be installed on the wall. The position of the first positioning bolt is adjusted by cooperating with the second mounting plate and the limiting groove, so that the first mounting plate can be installed and extended with the elevator guide rail body, achieving an adjustable effect, and preventing the elevator guide rail body from being inconvenient to be adjusted to the wall during use, affecting the overall applicability;

[0011] 2. The second mounting plate can be positioned after adjustment by cooperating with the provided mounting block, the second positioning bolt and the positioning hole. When the second mounting plate is adjusted, the mounting block is driven to move. At this time, the second positioning bolt can be inserted into one of the positioning holes for positioning, thereby achieving an effect of facilitating positioning and preventing the second mounting plate from being difficult to position and prone to skewing and shaking after adjustment.

[0018] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] Example:

[0020] like Figure 1-Figure 4As shown, an adjustable elevator guide rail comprises an elevator guide rail body 1, a first mounting plate 2 is provided below the elevator guide rail body 1, connecting plates 3 are fixedly connected to both sides of the elevator guide rail body 1 and the first mounting plate 2, an extension plate 4 is fixedly connected to the side of the lower connecting plate 3, a second mounting plate 5 is provided on the side of the upper connecting plate 3 and the lower connecting plate 3, a limiting groove 6 is provided on the surface of the connecting plate 3, a first positioning bolt 7 threadedly connected to the second mounting plate 5 is inserted in the limiting groove 6, and a positioning nut is threadedly connected to the end of the first positioning bolt 7 away from the second mounting plate 5.

[0021] The working principle of the above technical solution is as follows:

[0022] When it is necessary to adapt and adjust the gap between the elevator guide rail body 1 and the wall, first, the first mounting plate 2 can be held by hand and placed on the bottom surface of the elevator guide rail body 1, and then the second mounting plate 5 can be held by hand and placed on the side of the connecting plate 3. At this time, the first positioning bolt 7 can be rotated to insert it into the limiting groove 6 for installation, and then the positioning nut can be screwed together with the first positioning bolt 7 to block it. At this time, the first mounting plate 2 can be held by hand and moved away from the elevator guide rail body 1. When the first mounting plate 2 is moved, the first positioning bolt 7 can be adapted to move in the limiting groove 6 to the required position. When the movement is completed, the positioning nut can be rotated to fit the connecting plate 3 in a tight fit to position the first positioning bolt 7, thereby achieving an adjustable effect and preventing the elevator guide rail body 1 from being inconvenient to adapt to the wall and the required size when being installed on the wall, thereby affecting the overall feel of use.

[0023] In another embodiment, if Figure 1 and Figure 3 as well as Figure 4 As shown, mounting blocks 8 are fixedly connected to both sides of the second mounting plate 5, and the mounting blocks 8 are distributed in pairs. The surfaces of the mounting blocks 8 are threadedly connected with second positioning bolts 9. A plurality of evenly distributed positioning holes 10 are provided on the surface of the connecting plate 3 away from the elevator guide rail body 1 and the first mounting plate 2. The second positioning bolt 9 is located in one of the positioning holes 10. The second positioning bolt 9 is used to cooperate with the positioning hole 10 to improve the supporting effect on the second mounting plate 5.

[0024] When it is necessary to position and install the second mounting plate 5, the second mounting plate 5 can be first held and adjusted to a suitable position. At this time, the mounting block 8 can cooperate with the second mounting plate 5 to move to a suitable position, and then the second positioning bolt 9 can be rotated and inserted into the positioning hole 10 to complete the positioning. Moreover, since there are multiple positioning holes 10, the second mounting plate 5 can still cooperate with the mounting block 8 and the second positioning bolt 9 to be inserted into the positioning hole 10 when adjusting different positions, thereby achieving the effect of facilitating positioning and installation, and preventing the first positioning bolt 7 from being worn and loosened after long-term use.

[0025] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
