Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices for medium-weight components, specifically a simple rotary jack. Background Technology

[0002] With the rapid development of the national economy, rotary jacks, as the most common type of jack lifting equipment, are widely used in various industries due to their advantages such as being lightweight, easy to use, and simple in structure.

[0003] Currently, jacks are not commonly used equipment in daily life. Production is often delayed due to the lack of a jack. Therefore, it is crucial to know how to make a simple jack using readily available materials. Thus, a simple rotary jack is needed to solve the aforementioned technical problems. Utility Model Content

[0004] In view of this, the present invention provides a simple rotary jack, which solves the problem of production delays caused by the inability to find a jack during work.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A simple rotary jack includes: a support plate, a lead screw, a rotary nut, a rotating handle, a support washer, a sleeve, diagonal braces, and a bottom support plate. The support plate is welded to the lead screw, and the lead screw is fixedly connected to the rotary nut. The rotary nut has multiple rotating handles distributed circumferentially. One end of the sleeve is welded with a support washer, and the other end is fixedly connected to the bottom support plate. The sleeve has a vertical groove inside and is threaded to the lead screw. Multiple diagonal braces are distributed circumferentially on the side wall of the sleeve, and all of the diagonal braces are fixedly connected to the bottom support plate.

[0007] Furthermore, the lead screw is perpendicular to the support plate and is fully welded to the bottom center of the support plate.

[0008] Furthermore, a limiting rotation strip is welded to the bottom of the vertical groove in the lead screw to prevent the lead screw from rotating with the rotating nut.

[0009] Furthermore, the number of rotating handles is three, and adjacent rotating handles are arranged at a 120° angle.

[0010] Furthermore, the number of diagonal braces is four, and adjacent diagonal braces are arranged at a 90° angle.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model has a simple structure, is easy to manufacture, has an ingenious design, is flexible in operation, has a relatively high level of safety, and is widely applicable. It can withstand the lifting and lowering of medium-weight objects. Attached Figure Description

[0018] 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.

[0019] Please see the appendix Figure 1-2 This utility model provides a simple rotary jack, which includes: a support plate 1, a lead screw 2, a rotary nut 3, a rotating handle 4, a support washer 5, a sleeve 6, diagonal braces 7, and a bottom support plate 9. The support plate 1 is welded to the lead screw 2, and the lead screw 2 is fixedly connected to the rotary nut 3. The rotary nut 3 has multiple rotating handles 4 distributed circumferentially. One end of the sleeve 6 is welded with a support washer 5, allowing the lead screw 2 to pass freely in and out. The other end is fixedly connected to the bottom support plate 9. The sleeve 6 has a vertical groove inside, and the sleeve 6 is threadedly connected to the lead screw 2. Multiple diagonal braces 7 are distributed circumferentially on the side wall of the sleeve 6, and all of the diagonal braces 7 are fixedly connected to the bottom support plate 9.

[0020] Preferably, the lead screw 2 is arranged perpendicularly to the support plate 1 and is fully welded to the bottom center of the support plate 1.

[0021] Preferably, a limiting rotation strip 8 is welded to the bottom of the vertical groove in the lead screw 2 to prevent the lead screw 2 from rotating together with the rotating nut 3.

[0022] Preferably, there are three rotating handles 4, and adjacent rotating handles 4 are arranged at a 120° angle to facilitate turning the rotating nut 3.

[0023] Preferably, the number of the diagonal braces 7 is four, and the two adjacent diagonal braces 7 are arranged at a 90° angle, which increases the overall stability of the device.

[0024] The specific method of using this utility model is as follows:

[0025] In actual use, first place the simple rotary jack at the bottom of the object to be lifted, align the support plate 1 with the object, and after the bottom support plate 9 is set stably, rotate the handle 4 to turn the rotating nut 3, causing the lead screw 2 to lift and drive the support plate 1 to perform the lifting operation. After the operation is completed and the support is in place, rotate the handle 4 in the opposite direction to lower the lead screw 2, restore it to its original position, and then remove the simple rotary jack to complete the lifting operation.
