Description

Technical Field

[0001] This utility model relates to the technical field of elevator car guide rail fixing brackets, and in particular to an elevator car guide rail fixing bracket. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. During the installation of an elevator, the elevator guide rails need to be installed and fixed using elevator guide rail brackets.

[0003] Existing elevator guide rail brackets have poor stability and only moderate fixing effect on the guide rails. They may fall off after long-term use. Therefore, there is a need for an elevator guide rail car fixing bracket with better fixing effect to meet the needs of users.

[0004] An existing patent (publication number: CN219279196U) discloses a guide rail fixing bracket for elevator car. This utility model uses a guide rail bracket to install and fix the elevator guide rail. However, the existing elevator guide rail bracket has poor stability and a generally poor fixing effect on the guide rail. Long-term use will lead to the problem of falling off.

[0005] To address the aforementioned issues, existing patents offer solutions. However, the first and second mounting brackets in these patents have drawbacks in supporting and fixing guide rails. Their structures lack adjustment capabilities, relying solely on a fixed screw connected to the threaded hole of the guide rail. This prevents flexible adjustment of the screw's installation position based on the guide rail width, making it difficult to adapt to threaded hole connections for guide rails of different widths. Furthermore, the internal space of the first and second mounting brackets is not adjustable, making it impossible to accommodate guide rails of different thicknesses. These limitations prevent the overall fixing bracket from meeting the diverse usage requirements of various guide rails, severely restricting its application scope.

[0006] To address this, a guide rail fixing bracket for elevator car is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a guide rail fixing bracket for elevator car, which can solve the defects of the first and second mounting seats in the above-mentioned patent when supporting and fixing the guide rail. Their structure lacks adjustment function and only relies on the connection between the fixed screw and the threaded hole of the guide rail. It is impossible to flexibly adjust the installation position of the screw according to the width of the guide rail, which makes it difficult to adapt to the threaded hole connection of guide rails of different widths. At the same time, the internal space of the first and second mounting seats is not adjustable, which cannot meet the installation and use of guide rails of different thicknesses. These limitations make the overall fixing bracket unable to meet the diverse use needs of various guide rails, which seriously limits its application range.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a guide rail fixing bracket for an elevator car, comprising a mounting plate, wherein pre-installed structures are provided on both sides of the mounting plate, a guide rail is provided on the front side of the mounting plate, guide holes are provided on both sides of the front side of the guide rail, and adjustment and fixing components are provided on both sides of the top and bottom of the front side of the mounting plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 The present invention provides the following technical solution:

[0031] An elevator guide rail car guide rail fixing bracket includes a mounting plate 1, pre-installed structures 2 on both sides of the mounting plate 1, a guide rail 3 on the front side of the mounting plate 1, guide holes 4 on both sides of the front side of the guide rail 3, and adjustment and fixing components 5 on both sides of the top and bottom of the front side of the mounting plate 1.

[0032] The adjusting assembly 5 includes mounting seats 51 bolted to the top and bottom sides of the front side of the mounting plate 1. An adjusting plate 52 is provided on the front side of the mounting seat 51. The adjusting plate 52 is located in front of the guide hole 4. An adjusting groove 53 is provided on the front side of the adjusting plate 52. A first threaded rod 54 is provided on the front side of the adjusting plate 52. The rear side of the first threaded rod 54 passes through the interior of the adjusting groove 53. The rear side of the first threaded rod 54 is threadedly connected to the front side of the mounting seat 51. A fixing screw 55 is threadedly connected to the front side of the adjusting plate 52. The rear side of the fixing screw 55 passes through the interior of the guide hole 4. A positioning structure 56 is provided on the outer side of the adjusting plate 52. The positioning structure 56 contacts the guide rail 3.

[0033] In this embodiment: by setting up the pre-installed structure 2 and the adjusting and fixing component 5, the mounting plate 1 is quickly fixed in a suitable position through the pre-installed structure 2 in the initial stage of installation, thus building a stable basic framework for the subsequent installation of the guide rail 3. Later, when it is necessary to install guide rails 3 of different widths and thicknesses, the guide rail 3 is located in front of the mounting plate 1. The operator rotates the first threaded rod 54. Because the first threaded rod 54 is threadedly connected to the mounting base 51, and its rear side passes through the adjusting groove 53 of the adjusting plate 52, the adjusting plate 52 will move left and right along the adjusting groove 53. The movement allows the position of the fixing screw 55 to be flexibly changed, thereby accurately aligning with the guide holes 4 on guide rails 3 of different widths to achieve a stable connection. At the same time, the forward and backward movement adjusts the positioning structure 56 on the outer side of the adjusting plate 52, and makes the positioning structure 56 fit tightly against guide rails 3 of different thicknesses to achieve clamping and positioning of the guide rails 3. This ensures that the guide rails 3 will not shake or shift during operation, thus guaranteeing the safety and stability of elevator operation. The design of the entire adjusting and fixing assembly 5 greatly improves the versatility of various guide rails 3 and meets diverse usage needs.

[0034] Specifically, such as Figure 3As shown, the positioning structure 56 includes a connecting block 561 fixedly connected to the outside of the adjusting plate 52, and a threaded hole 562 is provided on the front side of the connecting block 561.

[0035] Specifically, such as Figure 3 As shown, a positioning screw 563 is threadedly connected to the inside of the threaded hole 562. A positioning disk 564 is rotatably connected to the rear side of the positioning screw 563. The rear side of the positioning disk 564 contacts the front side of the guide rail 3.

[0036] Specifically, such as Figure 3 As shown, a sliding hole 565 is provided on the front side of the positioning disk 564, and the sliding hole 565 is located on the outside of the fixing screw 55.

[0037] In this embodiment: By setting the positioning structure 56, after adjusting the connection between the fixing screw 55 and the guide holes 4 of different widths, in order to process the guide rails 3 of different thicknesses, the positioning screw 563 is rotated. Since the positioning screw 563 is threadedly connected to the threaded hole 562 on the connecting block 561, the positioning screw 563 will move back and forth. The positioning disk 564 rotatably connected to the rear side of the positioning screw 563 moves accordingly. The rear side of the positioning disk 564 is tightly attached to the front side of the guide rail 3. The sliding hole 565 allows the positioning disk 564 to move flexibly outside the fixing screw 55 without being obstructed by the fixing screw 55. The positioning disk 564 is attached to and clamped to the guide rail 3 to prevent the guide rail 3 from shaking or shifting during operation, ensuring the safety and stability of the elevator during subsequent operation, and enhancing the adaptability to guide rails 3 of different thicknesses.

[0038] Specifically, such as Figure 4 As shown, the pre-installed structure 2 includes pre-installed plates 21 disposed on both sides of the mounting plate 1, and the top and bottom of the front side of the pre-installed plate 21 are provided with second threaded rods 22.

[0039] Specifically, such as Figure 4 As shown, a connecting hole 23 is provided on the front side of the pre-installed plate 21, and a third threaded rod 24 is provided inside the connecting hole 23. The rear side of the third threaded rod 24 is threadedly connected to the front side of the mounting plate 1.

[0040] In this embodiment: by setting up a pre-installed structure 2, during installation, the second threaded rods 22 on both sides of the pre-installed plate 21 are first screwed into the corresponding holes in the wall or installation position for initial positioning. The connecting hole 23 on the front side of the pre-installed plate 21 cooperates with the third threaded rod 24, and the rear thread of the third threaded rod 24 is threaded to the front side of the mounting plate 1. Rotating the third threaded rod 24 can finely adjust the position and angle between the pre-installed plate 21 and the mounting plate 1, so that the mounting plate 1 can be accurately fixed in a suitable position, providing a stable and accurate foundation for the subsequent installation of the guide rail 3, effectively improving the overall installation efficiency and installation accuracy, and adapting to different installation environments and requirements.

[0041] Specifically, such as Figure 3As shown, a reinforcing pad 6 is bonded to the front side of the adjusting plate 52. The reinforcing pad 6 is located on the outer side of the front side of the adjusting groove 53, and the front side of the reinforcing pad 6 contacts the rear side of the first threaded rod 54.

[0042] Specifically, such as Figure 3 As shown, the rear side of the positioning disk 564 is coated with adhesive 7, and the rear side of adhesive 7 is bonded to the front side of the guide rail 3.

[0043] In this embodiment: By setting a reinforcing pad 6 and an adhesive 7, the reinforcing pad 6 is bonded to the front side of the adjusting plate 52, located on the outer side of the front side of the adjusting groove 53 and in contact with the rear side of the first threaded rod 54. This increases the friction between the first threaded rod 54 and the adjusting plate 52, preventing the first threaded rod 54 from loosening during elevator operation vibration, ensuring the stability of the adjusting plate 52, and thus ensuring the stable connection between the fixing screw 55 and the guide hole 4. The adhesive 7 on the rear side of the positioning plate 564 is bonded to the front side of the guide rail 3, further enhancing the fixing effect of the positioning plate 564 on the guide rail 3, preventing the positioning plate 564 from shifting after clamping the guide rail 3, improving the stability and reliability of the entire positioning structure 56, and ensuring the safety and stability of the guide rail 3 during elevator operation.

[0044] Specifically, such as Figure 5 As shown, an adhesive pad 8 is bonded to the rear side of the mounting plate 1. The adhesive pad 8 is made of elastic cotton material.

[0045] Specifically, such as Figure 5 As shown, a buffer pad 9 is adhered to the front side of the mounting plate 1, and the front side of the buffer pad 9 contacts the rear side of the guide rail 3.

[0046] In this embodiment: by setting the fitting pad 8 and the buffer pad 9, the fitting pad 8 on the rear side of the mounting plate 1 is made of elastic cotton material, which can fit tightly against the mounting surface, fill the tiny gaps between the mounting plate 1 and the mounting surface, enhance the stability of the mounting plate 1 installation, and reduce the friction and wear caused by vibration between the mounting plate 1 and the mounting surface. In addition, the buffer pad 9 on the front side of the mounting plate 1 contacts the rear side of the guide rail 3. During the subsequent elevator operation, the buffer pad 9 can buffer the vibration of the guide rail 3, protect the guide rail 3 and the mounting plate 1 from vibration damage, extend the service life of the guide rail 3, and also improve the smoothness and comfort of the elevator operation.

[0047] Working principle: During the use of the elevator guide rail 3 car fixing bracket, the first step is to prepare for installation. The second threaded rods 22 on both sides of the pre-installed plate 21 are screwed into the corresponding holes in the wall or installation location to complete the initial positioning. Then, the third threaded rod 24 in the connecting hole 23 on the front side of the pre-installed plate 21 is threaded to the front side of the mounting plate 1. The third threaded rod 24 is rotated to finely adjust the position and angle of the pre-installed plate 21 and the mounting plate 1, precisely fixing the mounting plate 1 in the appropriate position, thus building a stable frame for the subsequent installation of the guide rail 3. When installing the guide rail 3, according to the width of the guide rail 3, the operator rotates the first threaded rod 54. The first threaded rod 54 is threaded to the mounting base 51 and passes through the adjustment groove 53 of the adjusting plate 52. During rotation, the adjusting plate 52 moves left and right along the adjustment groove 53, causing the fixing screw 55 to precisely align with the guide holes 4 on guide rails of different widths, achieving a stable connection. Afterwards, the positioning screw 563 is rotated. The positioning screw 563 is threadedly connected to the threaded hole 562 on the connecting block 561. The movement of the positioning screw 563 drives the positioning disk 564, which is rotated and connected to the rear, to move. The positioning disk 564 moves flexibly outside the fixing screw 55 through the sliding hole 565 on the front side, closely fitting and clamping the guide rail 3 to prevent the guide rail 3 from shaking or shifting during operation. Then, during the elevator operation, the reinforcing pad 6 increases the friction between the first threaded rod 54 and the adjusting plate 52 to prevent the first threaded rod 54 from loosening due to vibration, ensuring that the fixing screw 55 and the guide hole 4 are firmly connected. The adhesive 7 on the rear side of the positioning disk 564 further enhances the fixing effect on the guide rail 3. The bonding pad 8 on the rear side of the mounting plate 1 is made of elastic cotton material, which fits tightly against the mounting surface to reduce vibration, friction and wear. The buffer pad 9 on the front side buffers the vibration of the guide rail 3, protects the guide rail 3 and the mounting plate 1, extends the service life of the guide rail 3, and improves the smoothness and comfort of the elevator operation.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
