Problems solved by technology

[0005] 1. Since the existing vehicle jack is supported by the entire bottom surface, on uneven ground, the existing vehicle jack is prone to uneven force or unstable support. In this case, either the jack and the ground should be selected. But at this time the top surface of the jack and the body cannot be effectively matched, or the top surface of the jack is selected to fit well with the body, but at this time only part of the bottom surface of the jack is in contact with the ground. Or body wear, or even plastic deformation failure;
[0006] 2. Since the bottom surface of the existing vehicle jack is a narrow plane, when the existing jack is used on a soft ground, it is likely that the car body has not been lifted, but the jack has already sunk

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] An embodiment of the present invention provides a supporting device, figure 1 is a structural schematic diagram of a support device provided by an embodiment of the present invention, such as figure 1 As shown, the support device is suitable for supporting and installing a vehicle jack, and the support device includes a platform 1, a fixed ring 5, at least three telescopic support rods 2, a support plate 3 corresponding to the support rods 2 and a support plate 3 corresponding to the support rods 2. The number of flexible restraints 4 corresponding to one by one, the number of support plates 3 is consistent with the number of support rods 2, the upper ends of the support rods 2 are respectively hinged to the bottom surface of th...

Abstract

The invention discloses a supporting device and a jack, belonging to the field of hand tools. The support device includes a platform, a length-adjustable support rod, a support plate, a flexible restraint and a fixed ring. The surface is hinged, the middle part of the support rod is connected to one end of the corresponding flexible restraint, and the other end of the flexible restraint is connected to the fixed ring through a distance adjustment member to adjust the length of the support rod and the angle of expansion to keep the platform level, and through the flexible Constraints and fixing rings fix the support rod, so that the support device can be placed stably on the uneven ground, ensure the stability of the vehicle jack placed on the platform, and make the vehicle jack fit well with the vehicle body, and at the same time the support plate increases the distance between it and the ground The contact area avoids the situation that when the vehicle jack is working on a soft ground, the vehicle body has not been jacked up, and the ground subsidence causes the vehicle jack to sink.

Description

technical field [0001] The invention relates to the field of hand tools, in particular to a supporting device and a jack. Background technique [0002] The jack is a lifting device with a small lifting height and simple and convenient use. [0003] The vehicle jack commonly used in automobiles is light and fast, and can meet the jacking up of small-tonnage automobiles to facilitate simple maintenance such as replacing spare tires and checking the chassis, so it is widely used. [0004] But, in the use process of vehicle-mounted jack, existing vehicle-mounted jack has following defect at least: [0005] 1. Since the existing vehicle jack is supported by the entire bottom surface, on uneven ground, the existing vehicle jack is prone to uneven force or unstable support. In this case, either the jack and the ground should be selected. But at this time the top surface of the jack and the body cannot be effectively matched, or the top surface of the jack is selected to fit well ...
