Description

Technical Field

[0001] This utility model relates to the field of easy-to-use jack technology, and more particularly to an easy-to-use jack. Background Technology

[0002] Jacks are most commonly used for changing tires and overhauling chassis. When a vehicle has a flat tire or needs to have its chassis components inspected, a jack is used to lift the corresponding support point on the vehicle body (such as the reinforcing rib under the door) to raise the tire off the ground, making it easier to remove the tire, replace brake pads, or handle chassis problems. It is a basic tool for car owners in emergencies and for auto repair shops.

[0003] An investigation revealed that patent CN211688052U discloses a user-friendly car jack, comprising a support base, a reinforcing base fixedly mounted on the lower surface of the support base, and lower support rods symmetrically mounted on the upper surface of the support base. A helical shaft is fixedly mounted at the upper end of one lower support rod, and a positioning shaft is fixedly mounted at the upper end of the other lower support rod. Upper support rods are movably connected to the upper ends of both lower support rods, and a transfer block is movably connected to the upper ends of both upper support rods. A load-bearing block is fixedly mounted at the upper end of the transfer block. This user-friendly car jack prevents tilting towards the sides of the support base, thus improving its stability during use. It also prevents the risk of breakage due to uneven force on the load-bearing axle caused by human error in the jacking starting point, or the risk of the load-bearing block slipping. Therefore, it provides excellent support and centering during use.

[0004] This patent can prevent the car's load-bearing axle from breaking due to uneven force caused by deviation of the jacking starting point caused by human judgment. However, the use scenarios of jacks are complex and diverse. When users use jacks on muddy and soft ground, the ground support for the jacks is unstable, which can easily cause the jacks to tip over. In addition, users need to squat down to rotate the screw when using jacks, which is not only inconvenient to operate, but also easily causes dirt to the user's clothes. Therefore, there is a need for a jack that is easy to use to meet the usage needs. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] like Figure 1-5As shown, this embodiment provides a convenient jack, including a jack body 1, a base 2 and a rotating block 3 on the jack body 1, an installation sleeve 4 installed at the bottom of the base 2, a detachable insert 5 installed inside the installation sleeve 4, a gear 6 installed at the end of the rotating block 3, a rack 7 meshing on the gear 6, a connecting rod 8 installed on the rack 7, a rod sleeve 9 sleeved on the connecting rod 8, and a handle 10 installed at the top of the rod sleeve 9; the insert 5 is installed and fixed in the installation sleeve 4, and then the jack body 1 is abutted against the car chassis. At this time, the multiple inserts 5 will provide stable support to the jack body 1. During the process of lifting the car, the inserts 5 will be inserted into the ground under force, thereby ensuring the stability of the jack body 1 when used on soft and muddy road sections and preventing the jack body 1 from tipping over during use. When it is necessary to drive the jack body 1 to lift the car, hold the handle 10 and pull the gear 6 to rotate through the rack 7. The gear 6 is located at the rotating end of the jack body 1. The rotation of the gear 6 will drive the jack body 1 to lift the car. Repeat the operation. The user does not need to squat down to operate the jack body 1, which avoids soiling the user's clothes and is more convenient to use.

[0026] To achieve rapid installation of the insertion post 5, an insertion block 11 is inserted into the mounting sleeve 4 and mounted on the insertion post 5. A locking rod 12 is slidably mounted on the mounting sleeve 4 and engages with the insertion block 11. A spring 13 is mounted on the locking rod 12, with the other end of the spring 13 mounted on the mounting sleeve 4. An anti-detachment component 14 is mounted on the mounting sleeve 4, and an anti-detachment block 15 is mounted on the locking rod 12 and slidably mounted within the anti-detachment component 14. Pulling the locking rod 12 outward and causing the anti-detachment block 15 to press against the inner wall of the anti-detachment component 14 will cause the locking rod 12 to be pulled out of the mounting sleeve 4. Then, inserting the insertion block 11 into the mounting sleeve 4 and releasing the locking rod 12 will cause the locking rod 12 to be inserted into the insertion block 11 under the reset action of the spring 13, thus fixing the insertion post 5 and enabling rapid installation of the insertion post 5.

[0027] To adjust the length of the connecting rod 8 and the sleeve 9 for user convenience, a fixing groove 16 is provided on the connecting rod 8. A pin 17 is slidably installed inside the sleeve 9, and the pin 17 is inserted into the fixing groove 16. A miniature bracket 18 is installed on the sleeve 9, and a rotating shaft 19 is rotatably installed inside the miniature bracket 18. A toggle block 20 and a rotating rod 21 are installed on the rotating shaft 19. The rotating rod 21 is movably mounted on the pin 17. A torsion spring 26 is installed on the miniature bracket 18 and the rotating rod 21. In the initial stage, the pin 17 is engaged in the fixing groove 16, which locks the position of the connecting rod 8 and the sleeve 9. Moving the toggle block 20 will rotate the rotating shaft 19, which in turn will rotate the rotating rod 21. The rotation of the rotating rod 21 will drive the pin 17 to be pulled out of the fixing groove 16, thus releasing the lock on the connecting rod 8 and the sleeve 9. The length of the connecting rod 8 and the sleeve 9 can be adjusted according to the user's height for convenient use.

[0028] To drive the pin 17 to move upward by rotating the lever 21, a circular block 22 is mounted on the pin 17, and a guide rail 23 is rotatably mounted on the lever 21. The guide rail 23 is slidably mounted inside the circular block 22. Rotating the lever 21 will cause the circular block 22 to slide inside the guide rail 23, and the circular block 22 will pull the guide rail 23 to move upward.

[0029] To prevent the pin 17 from being pulled out of the sleeve 9, a limiting block 24 is installed on the pin 17, and a limiting groove 25 is opened on the sleeve 9. The limiting block 24 is slidably installed in the limiting groove 25. When the pin 17 is pulled outward, the limiting block 24 abuts against the inner wall of the limiting groove 25 to prevent the pin 17 from being pulled out.

[0030] Working principle: In use, pull the lever 12 outwards, causing the anti-detachment block 15 to press against the inner wall of the anti-detachment component 14. At this time, the lever 12 will be pulled out from the mounting sleeve 4. Then, insert the insert block 11 into the mounting sleeve 4 and release the lever 12. Under the reset action of the spring 13, the lever 12 will be driven to insert into the insert block 11 to fix the insert post 5. Then, place the jack body 1 against the car chassis. At this time, the multiple insert posts 5 will provide stable support to the jack body 1. During the process of lifting the car, the insert posts 5 will be inserted into the ground under force, thereby ensuring the stability of the jack body 1 when used on soft and muddy roads and preventing the jack body 1 from tipping over during use. In the initial stage, the pin 17 is inserted into the fixing groove 16, which can lock the positions of the connecting rod 8 and the rod sleeve 9. When the jack body 1 needs to be driven to lift the car, hold the handle 10 and pull the gear 6 to rotate through the rack 7. The gear 6 is located at the rotating end of the jack body 1. The rotation of the gear 6 will drive the jack body 1 to lift the car. Repeat the operation. The user does not need to squat down to operate the jack body 1, avoiding soiling the user's clothes, and it is relatively convenient to use. Turning the lever 20 will drive the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 will drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 will drive the round block 22 to slide in the guide rail 23. The round block 22 will pull the guide rail 23 upward, and then the guide rail 23 will drive the pin 17 to be pulled out from the fixed groove 16. At this time, the locking of the connecting rod 8 and the rod sleeve 9 can be released. The length of the connecting rod 8 and the rod sleeve 9 can be adjusted according to the user's height for convenient use. After adjustment, release the lever 20. Under the reset action of the torsion spring 26, the pin 17 will be driven to re-lock into the corresponding fixed groove 16. When not in use, the connecting rod 8 and the rod sleeve 9 can be disassembled and separated for easy carrying.
