Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame manufacturing technology, specifically a hoisting tool for automotive seat frames. Background Technology

[0002] The car seat frame is the core support structure of the seat, typically made of high-strength steel or lightweight alloys, and formed through precision stamping and welding processes. It plays a crucial role in maintaining the seat shape, distributing body pressure, and connecting to the vehicle body, requiring sufficient strength and durability to withstand collision impacts and long-term use. The frame design must also consider ergonomics, rationally distributing support points to enhance seating comfort. Some high-end models also employ adjustable frames, allowing for multi-directional adjustments such as seat fore-aft position and backrest angle.

[0003] The lifting fixture for automotive seat frames is a device specifically designed for transporting automotive seat frames, with its core function being to achieve safe and efficient transfer of the frames. This fixture typically consists of a horizontal frame, a pneumatic balancer, a lifting device, an adjusting sleeve, and a protective mechanism. The horizontal frame, as the main framework, is connected to the steering mechanism via tension cables to achieve stable steering. The pneumatic balancer and lifting device are responsible for suspending the frame. The adjusting sleeve, connected to the threaded horizontal rod, allows for flexible adjustment of the horizontal position of the protective mechanism to accommodate frames of different sizes. The protective mechanism, composed of vertical partitions and anti-collision cork pads, effectively shields and protects adjacent frames from collision damage. Furthermore, the fixture features convenient adjustment and fixing functions. Through the cooperation of components such as side track windows and support threaded rods, the installation spacing and horizontal intervals of components such as the movable sleeve and bottom mounting plate can be easily adjusted to ensure the stability of the frame during lifting.

[0004] However, in order to ensure stability during lifting, the crane and hook of common car seat frame hoisting tools are fixed and difficult to rotate, which is not convenient for hoisting. In order to improve the convenience of hoisting, the connection between the crane and the hook is made to be rotating, but this is not stable enough. Therefore, a hoisting tool for car seat frames is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hoisting fixture for automotive seat frames, which has advantages such as convenient hoisting connection and stable hoisting connection, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hoisting fixture for an automobile seat frame includes a hoisting frame, two support plates fixedly installed at the bottom of the hoisting frame, three support beams arranged between the two support plates, and a rotating hoisting assembly fixedly installed at the top of the hoisting frame.

[0008] The rotating hoisting assembly includes a hoisting connecting cylinder fixedly installed on the top of the hoisting frame. A limiting gear is installed inside the hoisting connecting cylinder. A connecting rod is fixedly installed on the top of the limiting gear. A lifting ring is fixedly installed on the top of the connecting rod. A limiting internal gear ring is fixedly installed on the inner side wall of the hoisting connecting cylinder. The limiting gear and the limiting internal gear ring are compatible.

[0009] Furthermore, each end of the supporting beam has four mounting screw holes, and a mounting screw is inserted through one side of the supporting upright plate, with the mounting screw matching the mounting screw hole.

[0010] Furthermore, several lifting arms are fixedly installed on the opposite sides of the supporting beams, and fixed end plates are fixedly installed on the top of the lifting arms.

[0011] Furthermore, a limit end plate is fixedly installed on the top of the hoisting arm, and a compression spring is fixedly installed on one side of the fixed end plate.

[0012] Furthermore, a pressure end plate is fixedly installed at one end of the compression spring, and the limiting end plate at the top of the lower hoisting arm is offset from the limiting end plate at the upper arm.

[0013] Furthermore, each of the hoisting arms is fixedly installed with a reinforcing rib on the side that is far apart from each other, and one side of the reinforcing rib is fixedly installed on one side of the supporting beam.

[0014] Furthermore, six limiting plates are fixedly installed on each of the two supporting uprights on opposite sides, and the supporting crossbeam is located between the two limiting plates.

[0015] Compared with the prior art, this utility model provides a lifting fixture for automobile seat frames, which has the following advantages:

[0016] This lifting fixture for automotive seat frames features a rotating lifting component at the top of the lifting frame. A limiting internal gear ring is fixedly installed on the inner wall of the lifting connecting cylinder of the rotating lifting component. The lifting ring is mounted on the top of a connecting rod, and a limiting gear is fixedly installed at the bottom of the connecting rod. The limiting gear passes through the interior of the lifting connecting cylinder. During lifting, the limiting gear is pressed downwards, causing it to disengage from the limiting internal gear ring, facilitating the rotation of the lifting ring. After connection with the crane, the lifting ring is pulled upwards, engaging the limiting gear with the limiting internal gear ring to fix the limiting gear and prevent rotation of the lifting ring. This design allows the lifting ring to rotate when connected to the crane and to remain fixed during lifting. It solves the problem of common automotive seat frame lifting fixtures where the crane and hook are fixed to ensure stability during lifting, making rotation difficult and inconvenient. While a rotating connection between the crane and hook is used to improve ease of lifting, it is not always stable. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 4This embodiment of a hoisting fixture for an automobile seat frame includes a hoisting frame 1, two support plates 2 fixedly installed at the bottom of the hoisting frame 1, three support beams 3 arranged between the two support plates 2, and a rotating hoisting assembly fixedly installed at the top of the hoisting frame 1.

[0024] The rotating hoisting assembly includes a hoisting connecting cylinder 4 fixedly installed on the top of the hoisting frame 1. A limiting gear 5 is installed inside the hoisting connecting cylinder 4. A connecting rod 6 is fixedly installed on the top of the limiting gear 5. A hoisting ring 7 is fixedly installed on the top of the connecting rod 6. A limiting internal gear ring 8 is fixedly installed on the inner side wall of the hoisting connecting cylinder 4. The limiting gear 5 and the limiting internal gear ring 8 are compatible.

[0025] Specifically, when connecting the lifting ring 7 to the crane, the limiting gear 5 is pressed down, causing the limiting gear 5 to be misaligned with the limiting inner gear ring 8. The limiting gear 5 rotates inside the lifting connecting cylinder 4, causing the lifting ring 7 to rotate, which facilitates connection with the crane. After the connection is completed, the lifting ring 7 is pulled up, causing the limiting gear 5 to mesh with the limiting inner gear ring 8, fixing the limiting gear 5 and preventing the lifting ring 7 from rotating.

[0026] Please see Figure 1 and Figure 2 In this embodiment, four mounting screw holes 9 are provided at both ends of the supporting beam 3, and a mounting screw 10 is provided on one side of the supporting plate 2. The mounting screw 10 is adapted to the mounting screw hole 9.

[0027] Please see Figure 1 and Figure 2 In this embodiment, several lifting arms 11 are fixedly installed on the opposite sides of the supporting beams 3, and fixed end plates 12 are fixedly installed on the top of the lifting arms 11.

[0028] Among them, a limit end plate 13 is fixedly installed on the top of the hoisting boom 11, and a compression spring 14 is fixedly installed on one side of the fixed end plate 12.

[0029] Secondly, a pressure end plate 15 is fixedly installed on one end of the compression spring 14, and the limiting end plate 13 at the top of the lower lifting arm 11 is offset from the upper limiting end plate 13. When the car seat frame is placed between the pressure end plate 15 and the limiting end plate 13, the compression spring 14 pushes the limiting end plate 13 against the car seat frame, thus fixing the car seat frame.

[0030] Please see Figure 1 and Figure 3 In this embodiment, reinforcing ribs 16 are fixedly installed on the opposite sides of the hoisting arms 11, and one side of the reinforcing ribs 16 is fixedly installed on one side of the supporting beam 3.

[0031] Among them, six limiting plates 17 are fixedly installed on the opposite side of the two supporting upright plates 2, and the supporting crossbeam 3 is located between the two limiting plates 17.

[0032] The working principle of the above embodiment is as follows: When connecting the lifting ring 7 to the crane, the limiting gear 5 is pressed down, so that the limiting gear 5 is misaligned with the limiting inner gear ring 8. The limiting gear 5 rotates in the lifting connecting cylinder 4, so that the lifting ring 7 rotates, which facilitates the connection with the crane. After the connection is completed, the lifting ring 7 is pulled up, so that the limiting gear 5 meshes with the limiting inner gear ring 8, and the limiting gear 5 is fixed.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
