Description

Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to an outdoor emergency jack. Background Technology

[0002] In outdoor driving, wilderness rescue, and engineering emergency scenarios, jacks are core tools for lifting vehicles and supporting equipment. In outdoor environments, vehicle chassis heights vary significantly, and the lifting requirements for vehicles of different weights must be met. This places stringent demands on the jack's seat adjustment flexibility and load-bearing reliability. Bottle jacks, due to their compact structure and good portability, have become a common choice for outdoor emergencies.

[0003] However, the following drawbacks exist during use: First, the saddle adjustment capability of bottle jacks is significantly limited. The saddle is typically connected to the jack piston rod via a top thread, requiring manual rotation for fine-tuning. Single adjustments are usually limited to 3-5cm, making it unsuitable for lifting vehicles with varying chassis heights outdoors. For SUVs with higher chassis, additional stones or planks are needed to elevate the jack, increasing operational steps and safety risks. For cars with lower chassis, excessive adjustment can lead to excessively exposed saddle threads, affecting support stability. Second, the threaded load-bearing design poses a safety hazard. The connection between the saddle and piston rod of a bottle jack relies entirely on the threaded connection to transmit weight. Vehicles used for emergency lifting outdoors typically weigh between 1.5 and 3 tons. With prolonged or frequent use, the threaded surfaces are prone to plastic deformation, wear, and even stripping under continuous pressure. Especially in low-temperature outdoor environments, metal threads become more brittle and wear faster. Once the threads fail, the saddle may fall off, the vehicle may suddenly drop, and serious safety accidents may occur. Therefore, we have proposed an outdoor emergency jack. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an outdoor emergency jack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor emergency jack, comprising a bottle-type jack, a handle fixedly mounted on the side of the bottle-type jack, a telescopic rod slidably mounted on the top of the bottle-type jack, a secondary telescopic rod slidably mounted on the top of the telescopic rod, a saddle fixedly mounted on the top of the secondary telescopic rod, two clamping plates slidably mounted on the top of the saddle, mounting blocks fixedly connected to both sides of the telescopic rod, an adjusting rod rotatably mounted on the outer wall of the telescopic rod, an adjusting gear sleeved on the outer wall of the adjusting rod, and a synchronous plug-in assembly provided between the two mounting blocks.

[0006] Preferably, a rubber pad is fixed to the bottom inner wall of the saddle, and an inclined friction-enhancing strip is fixed to the surface of the rubber pad.

[0007] Preferably, both sides of the saddle are threaded with threaded screws, the ends of the two threaded screws extend into the saddle and are rotatably connected to the outer sides of the two clamping plates, and the outer walls of the two threaded screws are threaded with nuts corresponding to the outer sides of the saddle.

[0008] Preferably, the synchronous insertion assembly includes a straight rod, an adjusting plate, a return spring, a sliding sleeve, and a rack. A horizontal straight rod is fixedly connected to one side of each of the two mounting blocks that are close to each other. A sliding sleeve is slidably fitted onto the outer wall of each of the two straight rods. An integrated sealing rod is fixedly connected to one end of each of the two sliding sleeves that are close to each other. A return spring is fitted between the outer wall of each of the two straight rods and the inner wall of the mounting block and the sliding sleeve. An adjusting plate is fitted onto the outer wall of each of the two sliding sleeves. A rack is fixedly connected to the upper and lower sides of each of the two adjusting plates that are close to each other, corresponding to the upper and lower sides of the adjusting gear. The two racks are symmetrically arranged, and both racks mesh with the adjusting gear.

[0009] Preferably, the telescopic rod has interconnected positioning holes on both sides, and there are several sets of positioning holes.

[0010] Preferably, the positioning holes are distributed equidistantly from top to bottom, and the distance between two adjacent positioning holes is one centimeter, and the sealing rod is slidably inserted into the positioning holes.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model, through the sliding cooperation structure of the telescopic rod and the secondary telescopic rod, breaks through the limitation of traditional bottle jacks that rely solely on the saddle thread for fine adjustment, and realizes a wide range of saddle height adjustment. With the help of several sets of positioning holes, the lifting height can be precisely adjusted according to vehicles with different chassis heights. There is no need to lay additional stones, wooden boards or other auxiliary materials, avoiding safety hazards caused by unstable lifting tools. It effectively adapts to the diverse lifting needs in outdoor self-driving, wilderness rescue and other scenarios.

[0013] This invention abandons the traditional bottle jack's single load-bearing method that relies entirely on threads to transmit gravity. Instead, it uses a synchronous plug-in assembly to achieve height locking. After adjustment, the return spring drives the sealing rod on the sliding sleeve to insert into the positioning hole, forming a mechanical plug-in support structure. This structure, together with the sliding cooperation of the telescopic rod and the secondary telescopic rod, shares the load, significantly reducing the stress on the threaded connection. This avoids problems such as plastic deformation, wear, and stripping of the thread surface during long-term or frequent use. Especially in low-temperature outdoor environments, it effectively prevents the risk of failure caused by increased brittleness of metal threads, avoiding safety accidents such as saddle detachment and vehicle falls, and significantly improving load-bearing reliability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, an outdoor emergency jack is disclosed, comprising a bottle jack 1, a handle 2 fixedly mounted on the side of the bottle jack 1, a telescopic rod 3 slidably mounted on the top of the bottle jack 1, a secondary telescopic rod 4 slidably mounted on the top of the telescopic rod 3, a saddle 5 fixedly mounted on the top of the secondary telescopic rod 4, two clamping plates 8 slidably mounted on the top of the saddle 5, mounting blocks 11 fixedly connected to both sides of the telescopic rod 3, an adjusting rod 17 rotatably mounted on the outer wall of the telescopic rod 3, an adjusting gear 18 sleeved on the outer wall of the adjusting rod 17, and a synchronous plug-in assembly provided between the two mounting blocks 11.

[0023] A rubber pad 6 is fixedly installed on the bottom inner wall of the saddle 5, and an inclined friction-enhancing strip 7 is fixedly installed on the surface of the rubber pad 6.

[0024] Both sides of the saddle 5 are threaded with screw rods 9. The ends of the two screw rods 9 extend into the saddle 5 and are rotatably connected to the outer sides of the two clamping plates 8. Nuts 10 are threadedly fitted onto the outer walls of the two screw rods 9 corresponding to the outer sides of the saddle 5. The rubber pads 6 and the inclined friction-enhancing strips 7 at the bottom of the saddle 5 increase the friction with the bottom of the workpiece, reducing slippage during the support process. At the same time, rotating the screw rods 9 can drive the two clamping plates 8 to slide on the saddle 5, flexibly adjusting the clamping distance. This allows it to adapt to vehicle chassis or equipment support surfaces of different widths and further fix the workpiece through clamping. After adjustment, tightening the nuts 10 locks the position of the screw rods 9, ensuring the stability and reliability of the clamping plates 8. This solves the problems of poor adaptability and easy shifting of traditional saddles.

[0025] The synchronous plug-in assembly includes a straight rod 12, an adjusting plate 13, a return spring 14, a sliding sleeve 15, and a rack 16. A horizontal straight rod 12 is fixedly connected to one side of each of the two mounting blocks 11 that are close to each other. A sliding sleeve 15 is slidably fitted onto the outer wall of each of the two straight rods 12. An integrated sealing rod is fixedly connected to one end of each of the two sliding sleeves 15 that are close to each other. A return spring 14 is fitted between the outer wall of each of the two straight rods 12 and the inner wall of the mounting block 11 and the sliding sleeve 15. An adjusting plate 13 is fitted onto the outer wall of each of the two sliding sleeves 15. A rack 16 is fixedly connected to one side of each of the two adjusting plates 13 that are close to each other, corresponding to the upper and lower sides of the adjusting gear 18. The two racks 16 are symmetrically arranged and both racks 16 mesh with the adjusting gear 18.

[0026] The telescopic rod 3 has interconnected positioning holes 19 on both sides, and there are several sets of positioning holes 19.

[0027] Several sets of positioning holes 19 are evenly distributed from top to bottom, with a distance of one centimeter between adjacent positioning holes 19. The sealing rod is slidably inserted into the positioning hole 19. When adjusting the height, simply rotate the adjusting rod 17 counterclockwise. Through the meshing transmission of the adjusting gear 18 and the rack 16, the synchronous insertion assembly can be unlocked. After determining the height, release the adjusting rod 17, and the return spring 14 automatically drives the sealing rod to insert into the positioning hole 19 to complete the locking. The operation is simple and efficient. The adjustment of the clamping plate 8 can be achieved by rotating the threaded screw 9, without the need for complicated tools. The overall structural design simplifies the cumbersome adjustment steps of traditional jacks. Especially in outdoor emergency scenarios, it can quickly complete the lifting preparation work and improve the emergency response speed.

[0028] Working principle: When the height of the saddle 5 needs to be adjusted, the adjusting rod 17 is rotated counterclockwise. The two racks 16 gradually move away from each other due to the rotation of the adjusting rod 17. The two adjusting plates 13 slide on the two straight rods 12 and gradually move away from each other. The return spring 14 is deformed and shortened after being squeezed by the adjusting plate 13. The two sliding sleeves 15 gradually move away from each other on the outer wall of the straight rod 12 through the two adjusting plates 13 until the sealing rod at the end of the sliding sleeve 15 slides out of the positioning hole 19. At this time, the secondary telescopic rod 4 can be freely adjusted in height within the telescopic rod 3. After the height of the secondary telescopic rod 4 is determined, the adjusting rod 17 is released. The rebound force of the two return springs 14 is used to move the adjusting plate 13 on the straight rod 12. The springback allows the sealing rods on the two sliding sleeves 15 to re-insert into the positioning holes 19 where the secondary telescopic rod 4 stops inside the telescopic rod 3, thereby locking the height of the secondary telescopic rod 4. The saddle 5 is placed at the bottom of the work object, and the two clamping plates 8 are used to adapt to the bottom of the work object. When the width of the bottom of the work object is inconsistent with the width of the bottom of the work object, the two threaded screws 9 are rotated, so that they push the clamping plates 8 to slide on the saddle 5 through the threaded connection with the saddle 5, thereby adjusting the distance between the two clamping plates 8, so that the saddle 5 can flexibly adapt to different work objects. After the two clamping plates 8 are adjusted, the nut 10 is rotated on the threaded screw 9 so that it rotates to fit tightly against the outside of the saddle 5.
