Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a multifunctional filling jack. Background Art

[0002] A jack is a small and light lifting device that uses a rigid lifting piece as a working device to lift heavy objects within a small stroke through a top support or bottom claw. Jacks are widely used in transportation, factories, warehouses, construction projects and other departments, and are often used for vehicle repair, support and other work.

[0003] At present, a Chinese patent with publication number CN208648615U discloses a scissors jack, including a base, a first arm assembly, a second arm assembly, a lifting member and a screw nut adjustment mechanism, the first arm assembly includes a first support arm and a second support arm pivotally connected to each other, arranged opposite to each other in a first direction and forming a V-shape, the second arm assembly includes a third support arm and a fourth support arm pivotally connected to each other, arranged opposite to each other in the first direction and forming a V-shape, the lifting member is arranged opposite to the base in the first direction, the screw nut adjustment mechanism includes a handwheel, a screw and a nut, the nut is connected to the first arm assembly, the handwheel is connected to the screw, the screw and the nut are transmitted by thread and are suitable for pushing the second arm assembly to move toward or away from the first arm assembly in the second direction. Therefore, the scissor jack can quickly prop up the objects to be carried or quickly pull them out from under the carried objects through the hand wheel, making the operation of the scissor jack simpler and more convenient to use; although the invention solves the above defects, the following defects still exist: the existing jack is supported by only one lifting mechanism and one screw rod when in use, so the supporting effect is not good during use. When the lifting mechanism fails or loses pressure, accidents are likely to occur, which greatly reduces the safety of the jack and the stability of the support; at the same time, the existing jack is supported by only one screw rod for lifting and supporting. Since the pressure resistance of one screw rod is weak, the toughness of the screw rod is easily reduced after long-term use, which leads to unstable support or even breakage, which greatly reduces the support stability and safety of the jack. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing jacks do not have a filling effect, so they only rely on a lifting mechanism for support when in use, resulting in poor supporting effect and no safety guarantee; at the same time, a screw rod is used for lifting support, and long-term use leads to reduced toughness, insufficient supporting force and prone to support instability, and even breakage, thereby reducing the supporting effect and safety of the jack, and providing a multifunctional filling jack.

[0012] According to the above technical solution, the upper support arm and the lower support arm are connected by a mounting plate, and are rotatably connected, so that the lifting mechanism on both sides can support the lifting mechanism, and two screw rods running through the middle can push the lifting mechanism to rise, and at the same time can also provide fixed support for the lifting mechanism.

[0013] Furthermore, the ends of the screw rod a and the screw rod b away from the mounting plate pass through the driving mechanism, and the driving mechanism includes a transmission gear, a bearing, a first nut, a first gear, a second nut, a second gear, a hexagonal bolt and a fastening nut.

The first nut surface is provided with a first gear, and the second nut surface is provided with a second gear. Both ends of the transmission gear are respectively transmission-connected with the first gear and the second gear. A hexagonal bolt is fixed on the surface of the transmission gear, and the end of the hexagonal bolt away from the transmission gear extends outside the driving mechanism. The ends of the screw rod a and the screw rod b away from the driving mechanism are both provided with a fastening nut.

[0014] According to the above technical solution, the driving mechanism can effectively move on the two screw rods, thereby pushing the mounting plate to drive the lifting mechanism to move to one side to drive the lifting mechanism to work.

[0015] Furthermore, the lifting mechanism is arranged symmetrically and in a rectangular shape, and the screw rod a and the screw rod b are arranged in parallel.

[0016] According to the above technical solution, the lifting mechanism is symmetrically arranged on both sides, supported at the same time and rectangular on both sides, which further improves the support stability. The screw rod a and the screw rod b are arranged in parallel, which facilitates the horizontal movement of the driving mechanism and improves the support stability.

[0017] Compared with the prior art, the utility model has the following advantages: the multifunctional filling jack is installed with a steel ball filling structure, so when in use, as the lifting mechanism rises, it can also drive the sleeve to rise and fall and fill its internal cavity with steel balls to form a supporting effect, thereby achieving two supporting effects, greatly improving the safety and supporting effect of the jack, and also improving the functionality of the steel ball filling structure; the multifunctional filling jack is installed with two screw rods and a driving mechanism, avoiding support by a single screw rod, improving the supporting effect, and while effectively improving the supporting effect, it can also ensure the lifting efficiency of the jack, thereby further improving the practicality and safety of use of the jack.

DETAILED DESCRIPTION

[0028] See also Figure 1-9The present embodiment is a multifunctional filling jack, which is composed of a lifting mechanism, a top block 1, a base 2, a storage tank 5 and a discharging mechanism 11. The lifting mechanism is used to lift and support the top block 1, and the base 2 is used to place and support the entire jack. A sleeve 3 is fixedly installed at the bottom of the top block 1, and a feed pipe 4 is fixedly installed at one end of the sleeve 3. The feed pipe 4 is hollow inside and connected to the inside of the sleeve 3. A storage tank 5 is fixed on the top of the feed pipe 4. The top of the storage tank 5 is open and the bottom is connected to the feed pipe 4 to store steel balls 6. A first screw hole 7 is provided on one side of the storage tank 5 on the sliding path of the steel ball 6, and a first screw rod 8 is threadedly connected inside the first screw hole 7. The first screw rod 8 is used to block the rolling path of the steel ball 6. A support rod 9 is slidably connected inside the sleeve 3. The support rod 9 is fixedly installed with the base 2 at the bottom to play a supporting role. The top of the support rod 9 is inserted into the sleeve 3 for sliding, and a limit block 10 is provided on the top of the support rod 9. The diameter of the limit block 10 is wider than the opening at the bottom of the sleeve 3. A discharge mechanism 11 for the steel ball 6 is provided on the right side of the sleeve 3.

[0029] Furthermore, the discharge mechanism 11 is composed of a discharge pipe 111, a second screw hole 112 and a second screw rod 113. The discharge pipe 111 is installed on the right side of the sleeve 3 and is connected to the interior of the sleeve 3. The discharge pipe 111 is used to discharge the steel balls 6 in the sleeve 3. The second screw hole 112 is arranged on the inner top end of the discharge pipe 111. The second screw hole 112 is internally threadedly connected with a second screw rod 113. The second screw rod 113 serves to close the channel of the discharge pipe 111.

[0030] Furthermore, the discharge mechanism 11 is tilted downward by 35° as a whole, which complies with the principle of gravity and facilitates the discharge of the steel balls 6 in the sleeve 3. The end of the feed pipe 4 away from the sleeve 3 is located at the storage tank 5 and tilted upward by 35°, which complies with the principle of gravity and facilitates the steel balls 6 to roll into the sleeve 3. The top surface of the limit block 10 is tilted toward the discharge mechanism 11, which facilitates the internal steel balls 6 to slide to one side, thereby discharging the steel balls 6.

[0031] The working principle of this embodiment is as follows: when in use, first fill the storage tank 5 with steel balls 6, then install the second screw 113 into the second screw hole 112 to close the discharge pipe 111, and then remove the first screw 8 from the first screw hole 7 to open the feed pipe 4 channel. When the lifting mechanism rises upward and drives the top block 1 for support, the top block 1 drives the bottom sleeve 3 to move upward, thereby sliding upward on the surface of the support rod 9. Since the diameter of the limit block 10 at the top of the support rod 9 is larger than the bottom opening of the sleeve 3, the support rod 9 and the sleeve 3 will not separate. When the support rod 9 in the sleeve 3 is moved out, the internal cavity is formed. At this time, the steel balls 6 in the storage tank 5 enter the sleeve 3 along the feed pipe 4 for filling. When the sleeve 3 continues to rise, it can continue Steel balls 6 are placed in the storage tank 5 for filling. After the steel balls 6 fill the cavity in the sleeve 3, the supporting effect can be further improved. At the same time, the first screw rod 8 is threadedly connected to the first screw hole 7 to close the feed pipe 4. At this time, the feed pipe 4 and the discharge pipe 111 are closed, so that the internal steel balls 6 will not overflow, thereby achieving the supporting effect, greatly improving the supporting effect and stability of the jack, thereby improving the safety of the staff, and the steel ball filling function has a wide range of applications and can be applied to a variety of lifting devices, such as hydraulic jacks and other lifting devices; when the steel balls 6 are discharged, the second screw rod 113 is taken out to open the discharge pipe 111 channel. Since the top surface of the limit block 10 is inclined to one side, the internal steel balls 6 are discharged along the inclined surface to the outside of the discharge pipe 111.

[0032] Embodiment 2

[0033] This embodiment has a structure that is basically the same as that of the first embodiment, and adds the following features on the basis of the first embodiment: the lifting mechanism includes an upper support arm 12, a lower support arm 13 and a mounting plate 14, two upper support arms 12 are rotatably connected to the two ends of the top block 1, the two upper support arms 12 can rotate through a rotating shaft, the bottom ends of the two upper support arms 12 are rotatably connected to the mounting plates 14, and movable structures such as rotating shafts are installed on the mounting plates 14 on both sides. The upper support arms 12 are connected to the rotating structure on the mounting plates 14, so they can rotate, and at the same time, the lower support arms 13 are rotatably connected to the mounting plates 14 on both sides, and the bottom ends of the lower support arms 13 are rotatably connected to the base 2, and at the same time, a screw rod a15 and a screw rod b16 are movably connected between the two mounting plates 14, and at the same time, the two ends of the screw rod a15 and the screw rod b16 respectively penetrate the mounting plates 14 and move in the through holes of the mounting plates 14, and a driving mechanism 17 is slidably connected to the screw rod a15 and the screw rod b16, and the driving mechanism 17 can be bolt-driven and also can be hand-driven.

[0034] Furthermore, a driving mechanism 17 is passed through the ends of the screw rods a15 and b16 away from the mounting plate 14, and the driving mechanism 17 can push the mounting plate 14 to move to one side on the screw rods a15 and b16. The driving mechanism 17 includes a transmission gear 18, a bearing 19, a first nut 20, a first gear 21, a second nut 22, a second gear 23, a hexagonal bolt 24 and a fastening nut 25. The bearing 19 is fixedly mounted on the inner side wall of the driving mechanism 17, and a transmission gear 18 is mounted on the bearing 19. The transmission gear 18 rotates through the bearing 19. The first nut 20 and the second nut 22 are respectively threadedly connected to the screw rods a15 and b16. 16, and the first nut 20, the second nut 22 and the transmission gear 18 are on the same horizontal line. The first gear 21 is fixed on the surface of the first nut 20, and the second gear 23 is fixed on the surface of the second nut 22. They are located on both sides of the transmission gear 18, and the transmission gear 18 is respectively connected to the first gear 21 and the second gear 23 on both sides. A hexagonal bolt 24 or a square bolt is installed on the surface of the transmission gear 18, and the hexagonal bolt 24 extends outwardly through the outside of the driving mechanism 17 to facilitate use with a ratchet wrench. Two fastening nuts 25 are installed on the end of the screw rod a15 and the screw rod b16 away from the driving mechanism 17, that is, the other end.

[0035] Furthermore, the two lifting mechanisms are symmetrically arranged on both sides of the top block 1, and the two lifting mechanisms form a rectangular shape to enhance the supporting effect, and the screw rod a15 and the screw rod b16 are arranged in parallel in the middle of the jack to play a further supporting role.

[0036] The working principle of this embodiment is as follows: when in use, first rotate the fastening nut to make it close to one side of the mounting plate 14 to limit the movement of the mounting plate 14 on one side, and then use a tool such as a ratchet wrench to rotate the hexagonal bolt 24. At this time, the hexagonal bolt 24 drives the internal transmission gear 18 to rotate on the bearing 19. When the transmission gear 18 rotates, it also drives the first gear 21 and the second gear 23 at both ends to rotate. At the same time, the first gear 21 drives the first nut 20 to rotate, and the second gear 23 drives the second nut 22 to rotate. When the first nut 20 and the second nut 22 rotate on the screw rod a15 and the screw rod b16, the first nut 20 and the second nut 22 push the driving mechanism 17 slides to one side on the two screw rods, and when the driving mechanism 17 slides, it pushes the mounting plate 14 to one side. Since the mounting plate 14 at the other end is fixed by the fastening nut 25, the two mounting plates 14 are close to each other, thereby pushing the lifting mechanism to lift the top block 1 upward. When reaching a suitable height, the mounting plates 14 are limited by the fastening nuts 25 and the driving mechanism 17 respectively to prevent the mounting plates 14 from moving to both sides. Therefore, the two screw rods play a supporting and limiting role in the middle, just like a pry bar, further improving the supporting effect, avoiding the prior art of relying on only one screw rod for support and lifting, and improving the supporting effect. At the same time, the convenience and work efficiency of operation can be improved through the driving mechanism 17.

[0037] Embodiment 3

[0038] like Figure 5 and Figure 2 The screw rod jack and its steel ball filling structure shown in the figure include a screw rod jack body 26 and a movable rod 27, one end of the movable rod 27 is installed with a first fixed plate 28, the bottom of the first fixed plate 28 is fixedly installed with a sleeve 3, one end of the sleeve 3 is fixedly installed with a feed pipe 4, the feed pipe 4 is hollow inside and connected with the inside of the sleeve 3, a storage tank 5 is fixed on the top of the feed pipe 4, the top of the storage tank 5 is open and the bottom is connected with the feed pipe 4 to store the steel ball 6, one side of the storage tank 5 is provided with a first screw hole 7 on the sliding path of the steel ball 6, and the first screw hole 7 is fixed on the bottom of the storage tank 5. A first screw rod 8 is threadedly connected to the inside of the hole 7, and the first screw rod 8 is used to block the rolling path of the steel ball 6. A support rod 9 is slidably connected to the inside of the sleeve 3, and the support rod 9 is fixedly installed with the second fixed plate 29 at the bottom to play a supporting role. The second fixed plate 29 is installed to one end of the screw rod jack and is located below the first fixed plate 28. The top of the support rod 9 is inserted into the sleeve 3 for sliding, and a limit block 10 is provided on the top of the support rod 9. The diameter of the limit block 10 is wider than the opening at the bottom of the sleeve 3, and a discharge mechanism 11 for the steel ball 6 is provided on the right side of the sleeve 3.

[0039] Furthermore, the discharge mechanism 11 is tilted downward by 35° as a whole, which complies with the principle of gravity and facilitates the discharge of the steel balls 6 in the sleeve 3. The end of the feed pipe 4 away from the sleeve 3 is located at the storage tank 5 and tilted upward by 35°, which complies with the principle of gravity and facilitates the steel balls 6 to roll into the sleeve 3. The top surface of the limit block 10 is tilted toward the discharge mechanism 11, which facilitates the internal steel balls 6 to slide to one side, thereby discharging the steel balls 6.

[0040] The working principle of this embodiment is as follows: when in use, first fill the storage tank 5 with steel balls 6, then install the second screw rod 113 into the second screw hole 112 to close the discharge pipe 111, and then remove the first screw rod 8 from the first screw hole 7 to open the feed pipe 4 channel. When the screw rod jack body 26 rises upward and drives the movable rod 27 for support, the movable rod 27 drives the sleeve 3 under the first fixed plate 28 at one end to move upward, thereby sliding upward on the surface of the support rod 9. Since the diameter of the limit block 10 at the top of the support rod 9 is larger than the bottom opening of the sleeve 3, the support rod 9 and the sleeve 3 will not be separated. When the support rod 9 in the sleeve 3 is moved out, the internal cavity is formed. At this time, the steel balls 6 in the storage tank 5 enter the sleeve 3 along the feed pipe 4 to fill When the sleeve 3 continues to rise, steel balls 6 can be continuously placed in the storage tank 5 for filling. After the steel balls 6 fill the cavity in the sleeve 3, the supporting effect can be further improved. At the same time, the first screw 8 is threadedly connected to the first screw hole 7 to close the feed pipe 4. At this time, the feed pipe 4 and the discharge pipe 111 are closed, so that the internal steel balls 6 will not overflow, thereby achieving the supporting effect, greatly improving the supporting effect and stability of the screw jack, thereby improving the safety of the staff, and also reflecting that the steel ball filling structure can be applied to the screw jack. When the steel balls 6 are discharged, the second screw 113 is taken out to open the discharge pipe 111 channel. Since the top surface of the limit block 10 is inclined to one side, the internal steel balls 6 are discharged out of the discharge pipe 111 along the inclined surface.

A first screw rod 8 is threadedly connected to the sleeve 3, and the first screw rod 8 is used to block the rolling path of the steel ball 6. A support rod 9 is slidably connected inside the sleeve 3. The support rod 9 is fixedly installed with the second fixed plate 29 at the bottom to play a supporting role.

Since the diameter of the limit block 10 at the top of the support rod 9 is larger than the bottom opening of the sleeve 3, the support rod 9 and the sleeve 3 will not be separated. When the support rod 9 in the sleeve 3 is moved out, the internal cavity is formed. At this time, the steel balls 6 in the storage tank 5 enter the sleeve 3 along the feed pipe 4 for filling. When the sleeve 3 continues to rise, steel balls can be continuously placed in the storage tank 5. 6 is filled, and the supporting effect can be further improved after the steel balls 6 fill the cavity in the sleeve 3. At the same time, the first screw rod 8 is threadedly connected to the first screw hole 7 to close the feed pipe 4. At this time, the feed pipe 4 and the discharge pipe 111 are closed, so that the steel balls 6 inside will not overflow, thereby achieving the supporting effect, greatly improving the supporting effect and stability of the hydraulic jack, thereby improving the safety of the staff, and also reflecting that the steel ball filling structure can be applied to the hydraulic jack. When the steel balls 6 are discharged, the second screw rod 113 is taken out to open the discharge pipe 111 channel. Since the top surface of the limit block 10 is inclined to one side, the internal steel balls 6 are discharged out of the discharge pipe 111 along the inclined surface. At the same time, the steel pipe is not limited to steel ball filling, but also can be punched in the steel pipe for latch limit fixing, and the steel pipe can be extended in multiple sections to increase the supporting height.

[0048] The working principle of this embodiment is as follows: first, fill the storage tank 5 with steel balls 6, then install the second screw 113 into the second screw hole 112 to close the discharge pipe 111, and then remove the first screw 8 from the first screw hole 7 to open the feed pipe 4 channel. When the horizontal jack is lifted or lowered, the connecting plate 32 at the top of the sleeve 3 rotates on the first movable shaft 31 to adjust the angle of the sleeve 3 as the jack rises. At the same time, the bottom of the support rod 9 is also adjusted through the second movable shaft 33. At this time, the top block 1 drives the sleeve 3 to move upward through the first movable shaft 31, thereby sliding upward on the surface of the support rod 9. Since the diameter of the limit block 10 at the top of the support rod 9 is larger than the bottom opening of the sleeve 3, the support rod 9 and the sleeve 3 will not be separated. When the support rod 9 in the sleeve 3 is moved out, the internal cavity is created. At this time, the steel balls 6 in the storage tank 5 enter the sleeve 3 along the feed pipe 4 to fill When the sleeve 3 continues to rise, steel balls 6 can be continuously placed in the storage tank 5 for filling. After the steel balls 6 fill the cavity in the sleeve 3, the supporting effect can be further improved. At the same time, the first screw 8 is threadedly connected to the first screw hole 7 to close the feed pipe 4. At this time, the feed pipe 4 and the discharge pipe 111 are closed, so that the steel balls 6 inside will not overflow, thereby achieving the supporting effect. When the supporting angle is reached, the fastening block 34 is rotated to make it close to the base 2 to achieve the effect of fixing the support rod 9 and prevent it from rotating, which greatly improves the supporting effect and stability of the horizontal jack, thereby improving the safety of the staff. At the same time, it also reflects that the steel ball filling structure can be applied to the horizontal jack. When the steel balls 6 are discharged, the second screw 113 is taken out to open the discharge pipe 111 channel. Since the top surface of the limit block 10 is inclined to one side, the internal steel balls 6 are discharged out of the discharge pipe 111 along the inclined surface.
