Description

Technical Field

[0001] This utility model belongs to the technical field of jack accessories, and in particular relates to a jack anti-tilt base. Background Technology

[0002] A jack is a lightweight lifting and support device with a wide range of uses. In the construction of formwork and the connection of components (such as steel structures and precast slabs), jacks are used to assist in adjusting the height or applying pressure. In foundation treatment, jacks can be used to push or correct the position of components.

[0003] In building component support, when the contact surface between the bottom of the jack and the ground is uneven or the material of the leveling material is too soft, the bottom of the jack is prone to sinking or sliding, causing the whole structure to tilt. To address this, an anti-tilting base for the jack has been designed. This device increases the contact area between the jack and the ground through the use of a support base and a slotted plate. At the same time, the diagonal brace provides a fixed support effect for the main body of the jack, thereby preventing the jack from tilting. Utility Model Content

[0004] The purpose of this utility model is to provide a jack anti-tilt base, which can fix and support the main body of the jack, thereby preventing the jack from tilting, so as to solve the above-mentioned technical problems.

A movable support member is slidably connected to the surface of the round rod, and a positioning bolt is fixedly connected to the inner cavity of the movable support member. A diagonal brace is rotatably connected to the surface of the positioning bolt. A jack is fixedly connected to the inner cavity of the support base by bolts. Two semi-circular iron plates are sleeved on the surface of the jack lifting sleeve. The two semi-circular iron plates are fixedly connected to each other by bolts. A joint is welded to the opposite side of each of the two semi-circular iron plates. The top end of the diagonal brace is slidably connected to the inner cavity of the joint. A positioning bolt is fixedly connected between the joint and the top end of the diagonal brace.

[0006] Preferably, the top of the slotted plate has two limiting grooves, and the surface of the movable support member has two screw holes.

[0007] Preferably, the limiting groove and the screw hole are connected by a bolt through a common thread, and two protruding corners are welded to both the left and right sides of the support base.

[0008] Preferably, the slotted plate has two grooves on the side opposite to the support base, and the surface of the convex corner is slidably connected to the inner cavity of the groove.

[0009] Preferably, both the support base and the slotted plate have circular holes on their surfaces, and anchor bolts are slidably connected to the inner cavity of the circular holes.

[0010] Preferably, the inner cavity of each of the semi-circular iron-clad parts is fixedly connected with a rubber pad.

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

[0012] 1. This utility model achieves the effect of fixing and supporting the main body of the jack by sliding the movable support and rotating the diagonal brace until the top of the diagonal brace can slide into the inner cavity of the joint. Then, the positioning bolt is used to connect the diagonal brace to the semi-circular iron, and the movable support is fixed by bolts. This prevents the jack from tilting.

[0013] 2. By using the combination of convex corners and grooves, this utility model can limit the extreme position of the slotted plate's rotation, thus preventing the slotted plate from deflecting during the support base's support of the jack.

[0014] 3. By setting a rubber pad, this utility model can protect the inner cavity of the semi-circular iron-clad sleeve from the surface of the jack telescopic sleeve, thus preventing the inner wall of the semi-circular iron-clad sleeve from damaging the surface of the jack telescopic sleeve.

[0022] In the following description, embodiments of the anti-tilt base of the jack of this utility model will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-4 This invention illustrates an embodiment of a jack anti-tilt base, comprising a support base 1. Slotted plates 2 are rotatably connected to both sides of the support base 1. Round rods 3 are welded into the inner cavities of both slotted plates 2. Movable support members 4 are slidably connected to the surfaces of the round rods 3. Positioning bolts 5 are fixedly connected to the inner cavities of the movable support members 4. Diagonal bracing rods 6 are rotatably connected to the surfaces of the positioning bolts 5. A jack 7 is bolted to the inner cavity of the support base 1. Two semi-circular iron plates 8 are fitted onto the surface of the lifting sleeve of the jack 7. The two semi-circular iron plates 8 are bolted together. Joints are welded to opposite sides of the two semi-circular iron plates 8. The top end of the diagonal bracing rod 6 is slidably connected to the inner cavity of the joint. A positioning bolt 2 9 is fixedly connected between the joint and the top of the diagonal brace 6. Two limiting grooves 10 are opened on the top of the slotted plate 2. Two screw holes 11 are opened on the surface of the movable support 4. A bolt 12 is threadedly connected between the limiting grooves 10 and the screw holes 11. Two protruding corners 13 are welded on both the left and right sides of the support base 1. Two grooves 14 are opened on the side of the slotted plate 2 opposite to the support base 1. The surface of the protruding corner 13 is slidably connected to the inner cavity of the groove 14. Through the cooperation of the protruding corner 13 and the groove 14, the extreme position of the slotted plate 2 can be limited, which can prevent the slotted plate 2 from deflecting when the support base 1 supports the jack 7.

[0025] Example 2:

[0026] Figure 1-4 This invention illustrates an embodiment of a jack anti-tilt base, comprising a support base 1. Slotted plates 2 are rotatably connected to both sides of the support base 1. Round rods 3 are welded into the inner cavities of both slotted plates 2. Movable support members 4 are slidably connected to the surfaces of the round rods 3. Positioning bolts 5 are fixedly connected to the inner cavities of the movable support members 4. Diagonal bracing rods 6 are rotatably connected to the surfaces of the positioning bolts 5. A jack 7 is bolted to the inner cavity of the support base 1. Two semi-circular iron plates 8 are fitted onto the surface of the lifting sleeve of the jack 7. The two semi-circular iron plates 8 are bolted together. Both sides are welded with joints. The top of the diagonal brace 6 is slidably connected to the inner cavity of the joint. The joint and the top of the diagonal brace 6 are fixedly connected with a positioning bolt 9. The surfaces of the support base 1 and the slotted plate 2 are both opened with round holes 15. The inner cavity of the round hole 15 is slidably connected with an anchor bolt 16. The inner cavities of the two semi-circular iron clads 8 are fixedly connected with rubber pads 17. By setting the rubber pads 17, the inner cavity of the semi-circular iron clads 8 can be separated from the surface of the telescopic sleeve of the jack 7, thus avoiding damage to the surface of the telescopic sleeve of the jack 7 caused by the inner wall of the semi-circular iron clads 8.

[0027] Working principle: When using this utility model, the user rotates the two slotted plates 2 to unfold them. Then, the action of the convex angle 13 and the groove 14 makes the slotted plate 2 and the support base 1 on the same plane. Next, the jack 7 is fixedly connected to the inner cavity of the support base 1 with bolts. Then, the jack 7 is pressed to move the telescopic sleeve of the jack 7 to the appropriate position. Next, the two semi-circular iron plates 8 are fitted and fixed to the surface of the sleeve with bolts again. Then, the positioning bolt 5 is used to connect the diagonal brace 6 and the movable support 4. Then, the movable support 4 is slid and the diagonal brace 6 is rotated until the top of the diagonal brace 6 can slide into the inner cavity of the joint. Then, the positioning bolt 9 is used to connect the diagonal brace 6 and the semi-circular iron plates 8. At the same time, the movable support 4 is fixed with bolt 12, which then supports the jack 7. Then, the position of the support base 1 and the slotted plate 2 is fixed with anchor bolt 16, thereby fixing the main body of the jack 7 to prevent the jack from tilting.

[0028] In summary: This anti-tilt base for the jack achieves a fixed support effect for the main body of the jack 7 by sliding the movable support 4 and rotating the diagonal brace 6 until the top of the diagonal brace 6 can slide into the inner cavity of the joint. Then, the positioning bolt 2 9 is used to connect the diagonal brace 6 to the semi-circular iron 8, and the movable support 4 is fixed by using bolt 12. This prevents the jack from tilting.
