This utility model, through the design of the handle mechanism, allows for convenient installation and fixation of the handle body, making the assembly process simple and convenient, thus achieving the effect of facilitating the user's handling and transportation of the hydraulic jack body.

[0003] In the aforementioned patents or prior art, the density of a liquid decreases when heated in high temperatures, resulting in a failure to achieve the expected support effect. If workers unknowingly operate the hydraulic jack by mistake, there will be a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic jack with a temperature warning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic jack with a temperature warning function, comprising a hydraulic jack body, a fixed shell installed on one side of the hydraulic jack body, a sliding groove inside the fixed shell, an adjustment component inside the sliding groove, the adjustment component including a second bevel gear rotatably disposed below the sliding groove, a threaded rod fixedly connected to the upper end of the second bevel gear, a sliding column threadedly connected to the outer side of the threaded rod, a sliding hole opened above the fixed shell, and the sliding column slidingly connected to the sliding hole.

[0006] Furthermore, the sliding column is provided with multiple layers, and the multiple layers on the sliding column are set with different colors.

[0007] Furthermore, a connecting hole is provided on one side of the fixed shell, and the sliding groove is connected to the connecting hole. A through hole corresponding to the connecting hole is provided on one side of the hydraulic jack body.

[0008] Furthermore, a sliding sealing plate is slidably disposed within the sliding groove, a connecting rod is fixedly connected to one side of the sliding sealing plate, a fixing rod is fixedly connected to one side inside the sliding groove, and the connecting rod is slidably connected inside the fixing rod.

[0009] Furthermore, the space between the fixed rod and the connecting rod is filled with inert gas, and the sliding hole and the sliding groove are connected in a continuous manner.

[0010] Furthermore, the adjustment assembly also includes a drive rack installed below one side of the sliding sealing plate, a driven gear rotatably connected to one side of the sliding groove, the driven gear meshing with the drive rack, a crossbar fixedly connected to one side of the driven gear, a first bevel gear fixedly connected to the outside of the crossbar, and a second bevel gear meshing with the first bevel gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this hydraulic jack with temperature warning function is reasonable and has the following advantages:

[0012] (1) An adjustment component and connecting rod and fixed rod are installed inside the fixed shell. Through a unique temperature warning mechanism, the hydraulic jack status can be promptly reminded to the user in high temperature environment, thereby effectively avoiding damage to hydraulic components caused by high temperature. Under high temperature conditions, the pressure inside the hydraulic jack body will increase. This pressure change is transmitted to the sliding groove through the through hole and the connecting hole. Since the fixed rod and the connecting rod are filled with inert gas, the pressure remains unchanged. Therefore, the pressure inside the hydraulic jack body will push the sliding sealing plate to move. This movement is driven by the rack, driven gear, first bevel gear and second bevel gear, and finally drives the threaded rod to rotate, causing the sliding column to rise. The different color layers on the sliding column provide the staff with an intuitive temperature warning signal. By observing the color exposed on the sliding column, the staff can clearly judge whether the hydraulic jack body is within the safe working temperature range. This warning mechanism can not only effectively prevent hydraulic components from expanding, deforming or even bursting due to high temperature, but also avoid hydraulic oil leakage and component damage, thereby extending the service life of the hydraulic jack and improving the safety and reliability of the equipment.

[0013] (2) The temperature warning function is realized through mechanical transmission. The structure is simple and the maintenance cost is low. The entire warning system is mainly composed of sliding sealing plate, drive rack, driven gear, first bevel gear, second bevel gear, threaded rod and sliding column. These components are common mechanical components that are easy to process and assemble. During the operation, the pressure change in the hydraulic jack body is directly reflected in the rising height of the sliding column through mechanical transmission. There is no need for complex electronic components or sensors, which reduces the problem of false alarms or missed alarms caused by electronic component failures. In addition, since the working principle of the entire system is based on mechanical transmission, its maintenance and repair are relatively simple. It is only necessary to check the wear of each component regularly and perform necessary lubrication. This simple and reliable structural design not only reduces the maintenance cost of the equipment, but also improves the stability and reliability of the equipment, making it more suitable for use in various complex working environments.

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.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A hydraulic jack with a temperature warning function includes a hydraulic jack body 100. A fixed shell 200 is installed on one side of the hydraulic jack body 100. A sliding groove 201 is provided inside the fixed shell 200. An adjustment component is provided in the sliding groove 201. The adjustment component includes a second bevel gear 304 rotatably disposed inside the lower part of the sliding groove 201. A threaded rod 305 is fixedly connected to the upper end of the second bevel gear 304. A sliding column 306 is threadedly connected to the outer side of the threaded rod 305. A sliding hole 307 is provided on the upper part of the fixed shell 200, and the sliding column 306 is slidably connected to the sliding hole 307.

[0024] The sliding column 306 has multiple layers, and the multiple layers on the sliding column 306 are set with different colors.

[0025] The fixed shell 200 has a connecting hole 202 on one side, the sliding groove 201 is connected to the connecting hole 202, and the hydraulic jack body 100 has a through hole on one side corresponding to the connecting hole 202.

[0026] A sliding sealing plate 203 is slidably disposed in the sliding groove 201. A connecting rod 204 is fixedly connected to one side of the sliding sealing plate 203. A fixing rod 205 is fixedly connected to one side of the inside of the sliding groove 201. The connecting rod 204 is slidably connected inside the fixing rod 205. A stop block is fixedly connected to the lower part of the inside of the sliding groove 201. The stop block is used to limit the movement distance of the sliding sealing plate 203.

[0027] The space between the fixed rod 205 and the connecting rod 204 is filled with inert gas, and the sliding hole 307 is connected to the sliding groove 201.

[0028] The adjustment assembly also includes a drive rack 300 installed below one side of the sliding sealing plate 203. A driven gear 301 is rotatably connected to one side of the sliding groove 201. The driven gear 301 meshes with the drive rack 300. A crossbar 302 is fixedly connected to one side of the driven gear 301. A first bevel gear 303 is fixedly connected to the outside of the crossbar 302. A second bevel gear 304 meshes with the first bevel gear 303.

[0029] Working principle: Under high temperature conditions, the hydraulic jack body 100 will expand, deform, or even burst due to the high temperature, causing hydraulic oil leakage and component damage. At high temperature, the pressure inside the hydraulic jack body 100 increases. The pressure is transmitted through the through hole on one side of the hydraulic jack body 100 to the connecting hole 202, and then through the connecting hole 202 to the sliding groove 201. At this time, due to the inert gas, the pressure between the connecting rod 204 and the fixed rod 205 remains unchanged and is less than the pressure inside the hydraulic jack body 100. The internal pressure pushes the sliding sealing plate 203 to move away from the hydraulic jack body 100. The sliding sealing plate 203 drives the drive rack 300 to move, and the drive rack 300 meshes with the driven gear 301 to rotate. The driven gear 301 drives the first bevel gear 303 to rotate, and the first bevel gear 303 meshes with the second bevel gear 304 to rotate. At this time, the second bevel gear 304 drives the threaded rod 305 to rotate. The threaded rod 305 drives the sliding column 306 to rise through the thread. The sliding column 306 slides and rises in the sliding hole 307. Before using the hydraulic jack body 100, the operator can clearly see the sliding column 306 protruding from the sliding hole 307. By observing the color on the sliding column 306, the operator can judge whether the hydraulic jack body 100 is in a normal working state. This prevents the hydraulic jack body 100 from being used at high temperatures, which could cause the hydraulic components to expand, deform, or even burst, resulting in hydraulic oil leakage and component damage.
