Description

Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a lightweight waterproof jack with a braking structure. Background Technique

[0002] A jack refers to a light lifting device that uses a rigid lifting member as a working device to lift a heavy object within a small stroke through a top bracket or a bottom pawl. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. Its structure is light, firm, flexible and reliable, and can be carried and operated by one person.

[0003] For example, the patent with the authorized patent publication number CN218403476U discloses a jack, which includes: a jack body; a base, the base includes a first support member and a second support member, the jack body is installed on the first support member, and the second support member is movably connected to the first support member; wherein the base has an open state and a retracted state, and in the retracted state, the second support member supports on the installation surface, and in the open state, both the second support member and the first support member support on the installation surface. The jack of the present utility model, by setting the second support member, can make the second support member and the first support member jointly support on the installation surface when the base is in the open state, thereby increasing the contact area between the base of the jack and the installation surface, facilitating ensuring the stability of the jack, avoiding the problem of the jack tilting, improving the use safety of the jack, and improving the user experience.

[0004] However, the above-mentioned jack only increases the anti-tipping effect and does not have the function of braking and anti-slip. If the ground where it is supported is uneven or relatively inclined, it will easily cause the bottom support plate of the jack to slip during the process of lifting the heavy object, resulting in the tipping of the jack, which will cause serious safety accidents and endanger the lives of operators. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a lightweight waterproof jack with a braking structure to solve the problem that if the ground where it is supported is uneven or relatively inclined, it will easily cause the bottom support plate of the jack to slip during the process of lifting the heavy object, resulting in the tipping of the jack as mentioned in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A lightweight waterproof jack with a braking structure includes: a jack body and a docking plate. The lower end of the jack body is rotatably installed between two docking plates. The docking plates are fixedly installed on the upper surface of the braking and anti-slip mechanism. A turning handle penetrates into the control end of the jack body.

[0008] Preferably, the four sets of support arms of the whole jack are all in a U shape, and a plurality of annular grooves are formed on the outer surface to reduce the overall weight and enable the support arms to distribute stress more evenly.

[0009] Preferably, the whole jack is made of aluminum alloy material and its surface is coated with epoxy paint.

[0010] Preferably, the braking and anti-slip mechanism includes a brake plate and a sleeve seat. The brake plate is fixedly installed on the lower surface of the docking plate. Connecting arms are fixedly installed on both sides of the upper surface of the brake plate. The connecting arms slide in the sleeve seat, and anti-slip convex teeth are fixedly installed on the lower surface of the sleeve seat.

[0011] Preferably, a limit sliding opening is formed on the upper surface of the sleeve seat, and the connecting arm slides into the sleeve seat through the limit sliding opening.

[0012] Preferably, a top pressing plate is fixedly installed on the lower surface of the connecting arm. The top pressing plate is slidably installed in a ring cylinder. The ring cylinder is fixedly installed in the sleeve seat, and the upper surface of the top pressing plate abuts against the inner upper surface of the sleeve seat, so that it is limited and fixed in the ring cylinder.

[0013] Preferably, a sliding column is fixedly installed in the ring cylinder. The sliding column is slidably inserted in a guiding groove. The guiding groove is formed on the lower surfaces of the connecting arm and the top pressing plate and is communicated with each other;

[0014] Wherein, a spring is sleeved on the outer surface of the sliding column. The upper and lower ends of the spring respectively abut against the lower surface of the top pressing plate and the inner lower surface of the ring cylinder, so that it can apply a top supporting force to the top pressing plate, and the anti-slip convex teeth on the lower surface of the brake plate are suspended and sleeved inside the inner square opening of the sleeve seat.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. Through the design of the whole jack, the braking and anti-slip mechanism and the docking plate, when lifting a heavy object, the braking and anti-slip mechanism on the lower surface of the whole jack will abut against the ground. During the process of lifting the heavy object, the anti-slip end in the braking and anti-slip mechanism will automatically protrude therefrom and abut against the ground to increase the pressure between it and the ground, thereby increasing the friction with the ground to achieve the effect of braking and anti-slip. Moreover, the whole jack is made of aluminum alloy material, which not only ensures the strength but also reduces the weight, making it convenient for the staff to carry and operate. And the aluminum alloy material itself is a material with good anti-corrosion performance, because an oxide film will be formed on its surface, and this oxide film can effectively prevent the aluminum metal from being further corroded to achieve the purpose of waterproofing. And through the epoxy paint, a firm and durable surface coating can also be formed, which can further enhance the waterproof performance.

[0017] 2. Through the design of the sleeve seat, top pressure plate, ring cylinder, sliding column, spring, connecting arm and anti-slip convex teeth, when jacking up a heavy object, the sleeve seat on the lower surface of the whole jack will support on the ground. During the process of jacking up the heavy object, the connecting arm slidably installed in the sleeve seat will drive the top pressure plate to press into the ring cylinder, and make the top pressure plate touch one end of the spring sleeved on the outer surface of the sliding column. Furthermore, the spring can apply an upward elastic force to the top pressure plate, and at the same time, the brake plate at the lower end of the whole jack will slide down a certain distance. Until a certain pressure is reached, the brake plate will drive the anti-slip convex teeth on the lower surface to protrude from the square opening of the sleeve seat and touch the ground, thereby increasing the pressure and contact area with the ground, increasing the friction force to achieve the effect of braking and anti-slip, and preventing the whole jack from sliding or slipping during use;

[0018] And after use, the top pressure plate will push the brake plate into the square opening of the sleeve seat for storage by the elastic force applied by the spring, which can avoid being scratched by the anti-slip convex teeth during daily carrying. This design can prevent the anti-slip convex teeth from being exposed when not in use, reducing the risk of accidental injury. In this way, the operator is safer during carrying and use and will not be scratched by the sharp anti-slip convex teeth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 5 , the following technical solutions are provided in this embodiment:

[0027] As Figures 1 - 3 shown, a lightweight waterproof jack with a braking structure includes: the overall jack 1 and the docking plate 3. The lower end of the overall jack 1 is rotatably installed between two groups of docking plates 3. The docking plate 3 is fixedly installed on the upper surface of the braking and anti-slip mechanism 2. A turning handle 102 is inserted into the control end of the overall jack 1.

[0028] The four support arms 101 of the overall jack 1 are all in a U shape, and a plurality of annular holes are formed on the outer surface to reduce the overall weight and enable the stress of the support arms 101 to be more evenly distributed.

[0029] The overall jack 1 is made of aluminum alloy material and its surface is coated with epoxy paint.

[0030] Through the design of the overall jack 1, the braking and anti-slip mechanism 2 and the docking plate 3, when lifting a heavy object, the braking and anti-slip mechanism 2 on the lower surface of the overall jack 1 will support on the ground. During the process of lifting the heavy object, the anti-slip end in the braking and anti-slip mechanism 2 will automatically protrude to touch the ground to increase the pressure between it and the ground, thereby increasing the friction with the ground to achieve the effect of braking and anti-slip. Moreover, this overall jack 1 is made of aluminum alloy material, which not only ensures the strength but also reduces the weight, making it convenient for the staff to carry and operate. And the aluminum alloy material itself has good corrosion resistance because a layer of oxide film will form on its surface, and this oxide film can effectively prevent the aluminum metal from being further corroded to achieve the purpose of waterproofing. And a strong and durable surface coating can also be formed through the epoxy paint, which can further enhance the waterproof performance.

[0031] As Figures 4 - 5 shown, the braking and anti-slip mechanism 2 includes a brake plate 207 and a sleeve seat 201. The brake plate 207 is fixedly installed on the lower surface of the docking plate 3. Connecting arms 208 are fixedly installed on both sides of the upper surface of the brake plate 207. The connecting arms 208 slide in the sleeve seat 201. Anti-slip convex teeth 209 are fixedly installed on the lower surface of the sleeve seat 201.

[0032] A limit sliding opening 206 is formed on the upper surface of the sleeve seat 201 for the connecting arm 208 to slide into the sleeve seat 201.

[0033] A top pressure plate 202 is fixedly installed on the lower surface of the connecting arm 208. The top pressure plate 202 is slidably installed in the annular cylinder 203. The annular cylinder 203 is fixedly installed in the sleeve seat 201, and the upper surface of the top pressure plate 202 abuts against the upper surface inside the sleeve seat 201, so that it is confined in the annular cylinder 203.

[0034] A sliding column 204 is fixedly installed in the annular cylinder 203. The sliding column 204 is slidably inserted into the guide groove 210. The guide groove 210 is opened on the lower surfaces of the connecting arm 208 and the top pressure plate 202 and is connected and communicated;

[0035] Wherein, a spring 205 is sleeved on the outer surface of the sliding column 204. The upper and lower ends of the spring 205 respectively abut between the lower surface of the top pressure plate 202 and the lower surface inside the annular cylinder 203, so that it can exert a top support force on the top pressure plate 202, and the anti-slip convex teeth 209 on the lower surface of the brake plate 207 are suspended and sleeved inside the inner square opening of the sleeve seat 201.

[0036] Through the design of the sleeve seat 201, the top pressure plate 202, the annular cylinder 203, the sliding column 204, the spring 205, the connecting arm 208 and the anti-slip convex teeth 209, when performing a jacking operation on a heavy object, the sleeve seat 201 on the lower surface of the overall jack 1 will abut against the ground. During the process of jacking up the heavy object, the connecting arm 208 slidably installed in the sleeve seat 201 will drive the top pressure plate 202 to be pressed into the annular cylinder 203, and the top pressure plate 202 will abut against one end of the spring 205 sleeved on the outer surface of the sliding column 204. Furthermore, the spring 205 can exert an upward elastic force on the top pressure plate 202, and at the same time, the brake plate 207 at the lower end of the overall jack 1 will slide down a certain distance. Until a certain pressure is reached, the brake plate 207 will drive the anti-slip convex teeth 209 on the lower surface to protrude from the square opening of the sleeve seat 201 and abut against the ground, thereby increasing the pressure and contact area with the ground, increasing the friction force to achieve the effect of braking and anti-slip, and preventing the overall jack 1 from sliding or slipping during use;

[0037] And after use, the top pressure plate 202 will spring the brake plate 207 into the square opening of the sleeve seat 201 through the elastic force exerted by the spring 205 for storage. Furthermore, it can avoid being scratched by the anti-slip convex teeth 209 during daily carrying. This design can prevent the anti-slip convex teeth 209 from being exposed when not in use, reducing the risk of accidental injury. In this way, the operator is safer during carrying and use and will not be scratched by the sharp anti-slip convex teeth 209.

[0038] Summarize and sort out the working steps of this solution according to the above technical solution: When jacking up a heavy object, the sleeve seat 201 on the lower surface of the overall jack 1 will support on the ground. During the process of jacking up the heavy object, the connecting arm 208 slidably installed in the sleeve seat 201 will drive the top pressing plate 202 to press into the annular cylinder 203, and make the top pressing plate 202 touch one end of the spring 205 sleeved on the outer surface of the sliding column 204. Furthermore, the spring 205 can apply an upward elastic force to the top pressing plate 202, and at the same time, the brake plate 207 at the lower end of the overall jack 1 will slide down a certain distance. Until a certain pressure is reached, the brake plate 207 will drive the anti-slip convex teeth 209 on the lower surface to protrude from the square opening of the sleeve seat 201 and touch the ground, thereby increasing the pressure and contact area with the ground, and preventing the overall jack 1 from sliding or slipping during use, making it more stable during the supporting process.

[0039] In summary: When jacking up a heavy object and reaching a certain pressure, the anti-slip convex teeth 209 will protrude from the square opening of the sleeve seat 201 and touch the ground, increasing the pressure and contact area with the ground, thereby increasing the friction to achieve the anti-slip effect. And after use, the anti-slip convex teeth 209 can also be pushed and pulled back by the elastic force applied by the spring 205 to achieve the effect of automatic storage, so that it can be exposed when not in use, reducing the risk of accidental injury, and making the operator safer during carrying and use, and not being scratched by the sharp anti-slip convex teeth 209.
