Description

Technical Field

[0001] The utility model belongs to the technical field of jacks, and particularly relates to a horizontal jack with reinforced rear-wheel sides. Background Art

[0002] The horizontal jack is one of the relatively common existing automotive jacks. Its working principle is as follows: Press the handle, transmit force through the hydraulic pump, rotate the lifting arm, and raise the bracket and the tray on it at the distal end of the rotation of the lifting arm, so as to support the vehicle to rise. The load-bearing weight on the rear-wheel side of the existing horizontal jack is often relatively large. Also, since the rear wheels are directly installed on both sides of the wallboard assembly through single rear-wheel mounting brackets, this leads to the rear wheels being prone to bending and torsion outward relative to the wallboard assembly, which in turn may cause the wallboard assembly to deform, ultimately affecting the use of the jack. Therefore, the installation part of the rear wheels of the horizontal jack is one of the weak positions where damage is likely to occur in the entire structure.

[0003] In view of the above existing technology, it is necessary to reasonably improve the structure of the rear-wheel side of the existing jack. For this reason, the applicant has made a beneficial design, and the technical solution to be introduced below is generated under this background. Summary of the Utility Model

[0004] The task of the utility model is to provide a horizontal jack with reinforced rear-wheel sides, which installs reinforcing members on the rear-wheel side of the wallboard assembly to increase the strength of the wallboard assembly, making the jacking process of the jack more stable and the support of heavy objects more firm.

[0005] The task of the utility model is completed as follows. A horizontal jack with reinforced rear-wheel sides includes a handle, rear wheels, a wallboard assembly, front wheels, a bracket, a tray, and a lifting arm. The wallboard assembly is provided with the installation ends of the front wheels, the lifting arm, and the handle. The bracket is arranged on the extended end of the lifting arm, and the tray is arranged on the bracket. The rear wheels are respectively installed on both sides in the width direction at the rear end of the wallboard assembly. The feature is that both sides in the width direction at the rear end of the wallboard assembly are fixedly connected through a reinforcing member, thereby improving the strength of the rear-wheel side of the wallboard assembly.

[0006] In a specific embodiment of the utility model, the reinforcing member includes a handle and two connecting feet extending from the handle towards the wallboard assembly. The two connecting feet are respectively welded to both sides of the wallboard assembly.

[0007] In another specific embodiment of the utility model, a pair of rear-wheel mounting brackets are respectively arranged on both sides in the width direction at the rear end of the wallboard assembly. The rear-wheel mounting brackets are integrally or separately provided with the wallboard assembly, and rear wheels are installed below the rear-wheel brackets.

[0008] In yet another specific embodiment of the present utility model, the connecting feet extend to the rear wheel mounting bracket, and are integrated with the rear wheel mounting bracket to form an integrated rear wheel bracket that combines the reinforcing member and the rear wheel mounting bracket into one.

[0009] In still another specific embodiment of the present utility model, the reinforcing member is a plate-shaped reinforcing plate.

[0010] In still another specific embodiment of the present utility model, the reinforcing plate is a U-shaped structure.

[0011] In yet another specific embodiment of the present utility model, the reinforcing member is directly a handle, and the handle is directly welded between the two sides in the width direction at the rear end of the wallboard assembly.

[0012] In still yet another specific embodiment of the present utility model, the handle is a plate-shaped structure or a cylindrical structure.

[0013] Due to the adoption of the above structure, the present utility model has the beneficial effects that: a reinforcing member connecting the two sides of the wallboard assembly is added on the rear wheel side of the wallboard assembly of the jack, so that the connection and fixation between the two sides in the width direction at the rear end of the wallboard assembly are realized, thereby improving the strength of the rear wheel side of the jack, preventing the deformation of the wallboard assembly during the jacking process, and further avoiding affecting the use of the jack. Therefore, this structure strengthens the support and protection for the load, makes the jacking process of the jack more stable, and the support of the heavy object more firm.

[0019] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. However, the description of the embodiments does not limit the technical solutions. Any change in form rather than substance based on the concept of the present invention should be regarded as the protection scope of the present invention.

[0020] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on the positions shown in the corresponding drawings. It is only for the convenience of describing the technical solutions provided by the present invention in conjunction with the drawings and simplifying the description. Therefore, it cannot be understood as a special limitation on the technical solutions provided by the present invention.

[0021] Please refer to Figure 1 、 Figure 3 The present invention relates to a horizontal jack with reinforced rear wheels, including a handle 1, rear wheels 2, a wallboard assembly 3, front wheels 4, a bracket 5, a tray 6, a boom 7, a cover plate 8, and a hydraulic pump (not shown in the figure).

[0022] The front wheel shaft 41, the boom 7, the cover plate 8, the hydraulic pump, and the mounting end of the handle 1 are sequentially arranged on the wallboard assembly 3 in the length direction from front to back. The bracket 5 is arranged at the outer extending end of the boom 7, and the tray 6 is arranged on the bracket 5. When the handle 1 is pulled to drive the boom 7 to act, the tray 6 on the bracket 5 lifts the supported vehicle. Both ends of the front wheel shaft 41 pass through the front end of the wallboard assembly 3 and are installed with front wheels 4 through fasteners. Therefore, the front end of the wallboard assembly 3 has sufficient strength to support the vehicle without deformation through the setting of the front wheel shaft 41.

[0023] On both sides in the width direction at the rear end of the wallboard assembly 3, mounting reinforcements 10 are used to strengthen the strength of the rear wheel side of the wallboard assembly 3. Specifically, the reinforcements 10 are connected to both side surfaces in the width direction of the wallboard assembly 3 from the rear side of the wallboard assembly 3, so that the rear end of the wallboard assembly 3 is fixed together through the reinforcements 10, achieving the effect of improving the overall strength. The structure and installation method of the reinforcements 10 are elaborated in detail through the following embodiments. Embodiment 1

[0024] As Figure 1 、 Figure 2As shown, on both sides of the rear end of the wallboard assembly 3 in the width direction, a pair of rear wheel mounting brackets 21 are respectively provided. The rear wheel mounting brackets 21 can be integrally or separately provided with the wallboard assembly 3. A rear wheel 2 is installed below the rear wheel bracket 21. Specifically, the rear wheel 2 is a universal wheel. The reinforcing member 10 is a plate-shaped reinforcing plate 101. Specifically, the reinforcing plate 101 is a U-shaped structure. The reinforcing plate 101 includes a handle 1011 and two connecting feet 1012 extending from the handle 1011 towards the wallboard assembly 3. The two connecting feet 1012 are respectively welded to both sides of the wallboard assembly 3 to improve the strength of the rear end of the wallboard assembly 3 and prevent the rear wheel 2 from tilting. The reinforcing plate 101 not only realizes the function of holding the rear wheel but also provides the function of using the handle 1011 to carry the jack. Embodiment 2

[0025] As Figure 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that in this embodiment, the connecting feet 1012 extend to the rear wheel mounting bracket 21 to form an integral body with the rear wheel mounting bracket 21, forming an integrated rear wheel bracket 102 that combines the reinforcing member 10 and the rear wheel mounting bracket 21. Other structural features and installation methods are the same as those in Embodiment 1.

[0026] The structure of the handle 1011 is not limited. In both embodiments, the handle 1011 is a plate-shaped structure, and other shapes such as a cylindrical shape can also be used.

[0027] In addition, the reinforcing member 10 can directly be the handle 1011. The handle 1011 is directly welded between both sides of the rear end of the wallboard assembly 3 in the width direction, which also plays a role in increasing the strength of the rear end of the wallboard assembly 3.

[0028] Please continue to refer to Figures 1 to 4 , the working principle of a horizontal jack with rear wheel side reinforcement involved in the present utility model is as follows: When using this horizontal jack, move the jack of the present utility model. Hold the handle and lift the jack by hand to the working position where lifting is required. Place the tray 6 directly below the vehicle support position. Pull the handle 1 up and down to lift the vehicle to be supported to the required height. At this time, even if the vehicle has a heavy load, the rear wheel 2 will not cause the wallboard assembly 3 to deform.
