Description

Technical Field

[0001] This utility model relates to elevator components, and more particularly to an anti-loosening elevator guide rail bracket. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, used to transport passengers or goods up and down in multi-story buildings, and has the advantage of being convenient.

[0003] Elevators typically consist of a car, guide rails, and supports. The car moves up and down along the guide rails, which are fixed in the shaft by the supports. To facilitate adjustment, the supports usually have oblong holes. However, during the elevator's movement, the supports can easily shift internally, causing changes in the relative position of the guide rails and the shaft, which in turn leads to a decrease in the elevator's lifting performance. In addition, the supports usually include two support plates with different structures, which increases the complexity of their production and installation. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide an anti-loosening elevator guide rail bracket, which is not prone to internal displacement, has good anti-loosening performance, and is easy to manufacture and install.

[0005] Technical solution: An anti-loosening elevator guide rail bracket includes: The first and second support plates, which have the same structure, both include a plate body and a first oblong hole and a second oblong hole respectively provided on two sides of the plate body; The fastening assembly includes a bolt, a first nut, a locking sleeve, and a second nut, all threaded onto the bolt's shank. One end of the locking sleeve is threaded into the first nut, and the other end of the locking sleeve abuts against the second nut. The bolt's shank passes through a first oblong hole in the first support plate and a first oblong hole in the second support plate. The head of the bolt abuts against the body of the second support plate, and the first nut abuts against the body of the first support plate.

[0006] Optionally, the fastening assembly further includes: An internal thread is provided inside the first nut; An external thread is provided on one end of the anti-loosening sleeve; The internal thread and the external thread are mated.

[0007] Optionally, the fastening assembly further includes a gasket located between the head of the bolt and the body of the second support plate.

[0009] Optionally, both the first support plate and the second support plate further include reinforcing ribs, which are connected to both sides of the plate body.

[0010] Optionally, the number of the first waist-shaped holes and the number of the second waist-shaped holes are both two, one end of the reinforcing rib is located between the two first waist-shaped holes, and the other end of the reinforcing rib is located between the two second waist-shaped holes.

[0011] Optionally, both the first support plate and the second support plate may further include a reinforcing plate connected to the plate body.

[0012] Optionally, the connection between the reinforcing plate and the plate body is a bending connection.

[0013] Beneficial effects: (1) Since the first support plate and the second support plate have the same structure, only one type of support plate needs to be produced during production. During installation, only two support plates need to be used, which makes the production and installation less complicated. (2) The first nut is used to lock the plate body of the first support plate and the plate body of the second support plate. The anti-loosening cylinder is used to prevent loosening and further lock the plate body of the first support plate and the plate body of the second support plate. The second nut further locks the plate body of the first support plate and the plate body of the second support plate, so that the internal displacement of the anti-loosening elevator guide rail bracket of this scheme is not easy to occur, thereby preventing the relative position of the guide rail and the shaft from changing, and thus preventing the lifting performance of the elevator from deteriorating.

[0017] Example 1 like Figures 1-2This embodiment provides an anti-loosening elevator guide rail bracket, including: a first support plate 1 and a second support plate 2 with identical structures, each including a plate body 33 and a first oblong hole 31 and a second oblong hole 32 respectively provided on both sides of the plate body 33; a fastening assembly 4, including a bolt 44 and a first nut 41, an anti-loosening sleeve 43 and a second nut 42, all threadedly sleeved on the screw 442 of the bolt 44. One end of the anti-loosening sleeve 43 is threadedly sleeved in the first nut 41, and the other end of the anti-loosening sleeve 43 abuts against the second nut 42. The screw 442 of the bolt 44 passes through the first oblong hole 31 of the first support plate 1 and the first oblong hole 31 of the second support plate 2. The head 441 of the bolt 44 abuts against the plate body 33 of the second support plate 2. The first nut 41 abuts against the plate body 33 of the first support plate 1.

[0018] Specifically, the plate body 33 of the first support plate 1 and the plate body 33 of the second support plate 2 are detachably connected through the first oblong hole 31 and the fastening assembly 4. The first oblong hole 31 facilitates the adjustment of the relative horizontal position of the first support plate 1 and the second support plate 2. The plate body 33 of the first support plate 1 is also used to connect with the shaft through the second oblong hole 32 and the expansion bolt 44, etc. The plate body 33 of the second support plate 2 is also used to connect with the guide rail through the second oblong hole 32 and the bolt assembly, etc. The second oblong hole 32 facilitates the adjustment of the relative vertical position of the first support plate 1 and the shaft, and also facilitates the adjustment of the relative vertical position of the second support plate 2 and the guide rail. Since the first support plate 1 and the second support plate 2 have the same structure, in production... During production, only one type of support plate needs to be manufactured. During installation, only two support plates need to be used, which simplifies the production and installation process. The first nut 41 is used to lock the plate body 33 of the first support plate 1 and the plate body 33 of the second support plate 2. The anti-loosening cylinder 43 is used to prevent loosening and further lock the plate body 33 of the first support plate 1 and the plate body 33 of the second support plate 2. The second nut 42 further locks the plate body 33 of the first support plate 1 and the plate body 33 of the second support plate 2. This makes it easier for the internal displacement of the anti-loosening elevator guide rail bracket of this solution to be prevented, thereby preventing changes in the relative position of the guide rail and the shaft, and thus preventing a deterioration in the lifting performance of the elevator.

[0019] Furthermore, such as Figure 1 , Figures 3-4 The fastening assembly 4 further includes: an internal thread 411 located within the first nut 41; and an external thread 431 located outside one end of the anti-loosening sleeve 43; wherein the internal thread 411 and the external thread 431 are engaged. Specifically, the engagement of the internal thread 411 and the external thread 431 facilitates a threaded connection between one end of the anti-loosening sleeve 43 and the first nut 41.

[0020] Furthermore, such as Figure 1The fastening assembly 4 also includes a washer 45 located between the head 441 of the bolt 44 and the plate body 33 of the second support plate 2. Specifically, the washer 45 is used to increase the anti-loosening performance of the plate body 33 of the first support plate 1 and the plate body 33 of the second support plate 2.

[0021] Furthermore, such as Figure 1 The type of gasket 45 is either a flat gasket or a spring gasket. Specifically, flat gaskets facilitate the easy installation of gasket 45; spring gaskets facilitate the anti-loosening performance of gasket 45.

[0022] Furthermore, such as Figures 1-2 Both the first support plate 1 and the second support plate 2 also include reinforcing ribs 5, which are connected to both sides of the plate body 33. Specifically, the reinforcing ribs 5 are used to increase the strength of the first support plate 1 and the second support plate 2 and prevent deformation of the first support plate 1 and the second support plate 2.

[0023] Furthermore, such as Figure 2 The number of first oblong holes 31 and second oblong holes 32 are both two. One end of the reinforcing rib 5 is located between the two first oblong holes 31, and the other end of the reinforcing rib 5 is located between the two second oblong holes 32. Specifically, the two first oblong holes 31 and the two second oblong holes 32 facilitate the installation stability of the first support plate 1 and the second support plate 2.

[0024] Furthermore, such as Figures 1-2 Both the first support plate 1 and the second support plate 2 also include a reinforcing plate 6 connected to the plate body 33. Specifically, the reinforcing plate 6 is used to further increase the strength of the first support plate 1 and the second support plate 2 and prevent the first support plate 1 and the second support plate 2 from deforming.

[0025] Furthermore, such as Figures 1-2 The connection between the reinforcing plate 6 and the plate body 33 is a bending connection. Specifically, the bending connection facilitates the good integrity of the first support plate 1 and the second support plate 2.

[0026] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
