Description

Technical Field

[0001] This utility model belongs to the field of plastic steel seat technology, and in particular relates to a mounting bracket for plastic steel seats. Background Technology

[0002] With the diversification of market demand, especially the continuous upgrading of public passenger vehicles such as buses, people's requirements for seat specifications are constantly increasing. Plastic-steel seats are currently a relatively common type of seat, offering advantages in aesthetics, comfort, and structural strength due to the special properties of the material. In seat design and production, consumers focus on riding comfort, while passenger vehicle designers focus on the layout of the bus's interior space, resulting in various specific requirements for seat dimensions.

[0003] In existing installations of plastic steel seats, the mounting holes on the bottom of the seat are aligned with the mounting holes on the top of the mounting bracket, and then bolts and fasteners are used to fix the seat to the bracket. However, because plastic steel seats come in different sizes, the positions of the mounting holes on the bottom vary, requiring different mounting brackets for different sizes. Existing mounting brackets are all fixed and cannot be adjusted to accommodate different seat sizes, resulting in poor practicality and failing to meet current installation needs. Therefore, we propose a mounting bracket for plastic steel seats. Utility Model Content

[0004] The purpose of this utility model is to provide a mounting bracket for plastic steel seats to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a mounting bracket for a plastic steel seat, comprising:

[0006] Two base rods, each base rod has a support block fixedly installed on its top surface, and each support block has a top rod fixedly installed on its top surface. One of the top rods and one of the base rods have multiple mounting tubes fixedly installed on one side, and each of the multiple mounting tubes has a telescopic rod slidably installed inside it. One end of each of the multiple telescopic rods is fixedly connected to one side of the other top rod and the other base rod, respectively.

[0007] An adjustment assembly is provided on two support blocks and is used to adjust the distance between the two bottom rods and the two top rods;

[0008] Two fixed blocks are respectively fixedly installed on the top surfaces of two top rods. A movable block is slidably installed on the top surface of each of the two top rods. An installation groove is opened on the top surface of both the movable block and the two fixed blocks.

[0009] Two sets of moving components are respectively disposed in two top rods and are used to drive two moving blocks to move.

[0010] In the above technical solution, the adjusting component further includes two movable seats, which are slidably installed on one side of one of the support blocks, and two fixed seats are fixedly installed on one side of the other support block. A connecting rod is rotatably installed in each of the two movable seats, and the other ends of the two connecting rods are rotatably installed in the two fixed seats respectively. When the two movable seats move, the distance between the two support blocks is adjusted by the cooperation between the two movable seats and the two fixed seats. When the distance between the two support blocks changes, the distance between the two bottom rods and the two top rods also moves with the two support blocks.

[0011] In the above technical solution, the adjusting component further includes a cavity, which is disposed within one of the support blocks. Two racks are slidably installed within the cavity, and a gear is rotatably installed within the cavity. The two racks are located on opposite sides of the gear and mesh with it. One side of one of the support blocks has two side grooves, and sliders are slidably installed within each side groove. One end of each slider is fixedly connected to one side of each of the two movable seats, and the other end of each slider is fixedly connected to one side of each of the two racks. When one rack moves, it drives the gear to rotate, and when the gear rotates, it drives the other rack to move. When both racks move, the two movable seats move via the two sliders.

[0012] In the above technical solution, furthermore, an electric push rod is fixedly installed on the top surface of one of the bottom rods, and the top end of the electric push rod is fixedly connected to the bottom end of one of the racks, so that activating the electric push rod pushes one of the racks to move.

[0013] In the above technical solution, the movable component further includes a top groove, which is formed on the top surface of the top rod. A lead screw is rotatably installed in the top groove, and a threaded sleeve is threadedly connected to the lead screw. The threaded sleeve is slidably connected to the top groove, and the top end of the threaded sleeve is fixedly connected to the bottom surface of the movable block. When the lead screw rotates, the movable block will move through the threaded sleeve, thereby adjusting the distance between the movable block and the fixed block, so that the mounting grooves on the fixed block and the movable block are aligned with the mounting holes on the plastic steel seat, which facilitates the subsequent installation and fixing of the plastic steel seat with bolts and fasteners.

[0014] In the above technical solution, furthermore, an adjusting block is rotatably installed on one side of each of the two top rods, and one end of each of the two adjusting blocks is fixedly connected to one end of each of the two lead screws. Rotating the adjusting block can drive the lead screw to rotate.

[0015] In the above technical solution, furthermore, multiple fixing plates are fixedly installed on both sides of the two base rods, and fixing holes are opened on the top surface of the multiple fixing plates. The base rods are conveniently installed through the fixing plates and fixing holes, so as to realize the installation and fixing of the base rods.

[0016] The beneficial effects of this utility model are:

[0017] 1. The mounting bracket for this plastic steel seat allows the plastic steel seat to be installed on two top rods. Based on the mounting holes on different sizes of plastic steel seats, an electric push rod is activated to move one of the racks. Activating one rack causes a gear to rotate, which in turn moves the other rack. As both racks move, two sliders move two movable seats. The movement of these movable seats, in conjunction with the two fixed seats, adjusts the distance between the two support blocks. When the distance between the two support blocks changes, the distance between the two bottom rods and the two top rods also moves along with the two support blocks.

[0018] 2. The mounting bracket for this plastic steel seat, after adjusting the distance between the two top rods, rotates the adjusting block to drive the lead screw to rotate according to the position of the mounting holes on the plastic steel seat. When the lead screw rotates, it will drive the moving block to move through the threaded sleeve, thereby adjusting the distance between the moving block and the fixed block, so that the mounting grooves on the fixed block and the moving block are aligned with the mounting holes on the plastic steel seat, which facilitates the subsequent installation and fixing of the plastic steel seat with bolts and fasteners.
