Technical Field

[0001] This utility model relates to the technical field of horizontal jack structure, and in particular to a horizontal jack capable of bearing 1.5T. Background Technology

[0002] Horizontal jacks are a type of jack. Their horizontal structure ensures the stability of the jack during operation and is the most common type of jack used in daily life.

[0003] Most existing horizontal jacks require manual force to continuously raise the boom during operation. Due to the leverage effect, most existing power arms are relatively long in order to save as much effort as possible, which makes it inconvenient to store the horizontal jack later and cannot be effectively stored. In order to solve this problem, a horizontal jack that can bear a load of 1.5T is proposed. Utility Model Content

[0004] This invention provides a horizontal jack capable of supporting 1.5T, which solves the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A horizontal jack capable of bearing 1.5T includes a jack body, wherein the jack body includes a mounting bracket and a power structure;

[0007] The mounting bracket includes a push rod for lifting and transmitting power to the power structure;

[0008] The power structure includes a first power arm and a second power arm. The first power arm and the second power arm are hinged together. The right end of the first power arm extends towards the side near the second power arm and protrudes to form a limiting boss for rotating and limiting the second power arm. The second power arm is recessed near the limiting boss to form a slot. The limiting boss and the slot cooperate to allow the second power arm to be in two states. In the first state, the limiting boss is engaged in the slot, and the first power arm cannot rotate clockwise. At this time, the power structure can be driven downward. In the second state, the second power arm rotates counterclockwise along the first power arm, and the power structure is in a retracted position.

[0009] The second power arm is also provided with a limiting part on its outer periphery for limiting the rotation of the second power arm.

[0010] Preferably, the limiting part includes a limiting sleeve threadedly connected to the outer periphery of the second power arm, the limiting sleeve sliding along the axial direction of the second power arm, and the limiting sleeve slidingly extending to the outer periphery of the first power arm for rotational limiting.

[0011] Preferably, the left end face of the first power arm is provided with a storage groove for the second power arm to rotate and be stored.

[0012] Preferably, the top of the second power arm is detachably connected to an adjustment component for extending the power structure. The adjustment component includes a plurality of extension columns connected end to end. The bottom of the extension column is provided with a threaded groove, and the top protrudes outward to form a threaded protrusion that cooperates with the threaded groove.

[0013] Preferably, the top of the second power arm is threadedly connected to the bottom of the extension column, and a connecting column that cooperates with the extension column is also provided at the top of the adjusting member. The top of the connecting column is provided with a grip bar that is easy for the operator to hold.

[0014] Preferably, the bottom of the mounting bracket is provided with a pulley system for moving the jack body.

[0015] The advantages and positive effects of this utility model are as follows: by setting up the mounting bracket and the power structure, a stable jack structure can be formed. Furthermore, by rotating the first and second power arms within the power structure, the power arms can be rotated and stored when not in use, facilitating the subsequent placement of the entire jack. Additionally, the setting of the limiting sleeve can limit the rotation of the power arms during operation, thereby enabling the operator to orderly press down the power arms. The setting of the adjusting component can meet the requirements for the length of the power arms under different conditions. Attached Figure Description

[0024] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0025] Reference Figure 1 and Figure 2 As shown, a horizontal jack is a type of jack. Its horizontal structure ensures the stability of the entire jack during operation and is the most common type of jack in daily life. Most existing horizontal jacks require manual force to continuously raise the lifting rod 111 during operation. Due to the leverage effect, and in order to save effort, most existing power arms are quite long, leading to inconvenience and ineffective storage of the horizontal jack. To solve this problem, a horizontal jack capable of bearing 1.5T is proposed; it includes a jack body 1, which includes a mounting bracket 11 and a power structure 2.

[0026] The mounting bracket 11 includes a push rod 111 for being driven and lifted by the power structure 2;

[0027] The power structure 2 includes a first power arm 21 and a second power arm 121. The first power arm 21 and the second power arm 121 are hinged together. The right end of the first power arm 21 extends towards the side near the second power arm 121 and protrudes to form a limiting boss for rotating the second power arm 121. The second power arm 121 is recessed near the limiting boss to form a slot. The limiting boss and the slot cooperate to allow the second power arm 121 to be in two states. In the first state, the limiting boss is engaged in the slot, and the first power arm 21 cannot rotate clockwise. At this time, the power structure 2 can be driven downward. In the second state, the second power arm 121 rotates counterclockwise along the first power arm 21. At this time, the power structure 2 is in a retracted position.

[0028] The outer periphery of the second power arm 121 is also provided with a limiting part 12 for limiting the rotation of the second power arm 121; by setting up the mounting bracket and the power structure, a stable jack structure can be formed, and by setting up the rotation of the first power arm and the second power arm in the power structure, the power arm can be rotated and stored in the unused state, which is convenient for the subsequent placement of the entire jack. Furthermore, by setting up the limiting sleeve, the rotation of the power arm in the working state can be limited, thereby realizing the purpose of the operator to press down the power arm in an orderly manner. By setting up the adjustment part, the length requirements of the power arm under different conditions can be met.

[0029] It should be noted that the specific structure of the limiting part 12 is as follows: the limiting part 12 includes a limiting sleeve 22 threadedly connected to the outer periphery of the second power arm 121. The limiting sleeve 22 slides along the axial direction of the second power arm 121 and extends to the outer periphery of the first power arm 21 for rotational limiting. By setting the limiting sleeve 22, when the jack needs to be used, the second power arm 121 is rotated and extended along the first power arm 21 until the second power arm 121 and the first power arm 21 are coaxial to form a stable power rod. At this time, the limiting sleeve 22 is rotated along the second power arm 121 until the limiting sleeve 22 is inserted into the first power arm 21. At this time, the rotation between the first power arm 21 and the second power arm 121 is limited, ensuring sufficient stability for the operator during the pressing process.

[0030] Furthermore, a storage groove 211 is provided on the left end face of the first power arm 21 for the second power arm 121 to rotate and store; the storage groove 211 can achieve the purpose of orderly storage of the entire power arm structure during the storage of the jack.

[0031] It should also be noted that a friction pad is provided on the outer circumferential surface of the limiting sleeve 22; the friction pad makes it convenient for the operator to rotate the limiting sleeve 22.

[0032] Furthermore, to enhance the practicality of the power arm, in this embodiment, the top of the second power arm 121 is detachably connected to an adjustment member 3 for extending the power structure 2. The adjustment member 3 includes several extension columns 31 connected end to end. The bottom of each extension column 31 is provided with a threaded groove 32, and the top protrudes outward to form a threaded protrusion that cooperates with the threaded groove 32. The arrangement of several extension columns 31 connected end to end in the adjustment member 3 can ensure the purpose of lengthening or shortening the power arm, thereby meeting the different needs of the power arm under different circumstances.

[0033] Additionally, the aforementioned extension posts 31 can be connected and tightened in an orderly manner with threads to ensure the stability of the subsequent pressing process.

[0034] It is worth mentioning that the top of the second power arm 121 is threadedly connected to the bottom of the extension column 31, and a connecting column 34 that cooperates with the extension column 31 is also provided at the top of the adjusting member 3. The top of the connecting column 34 is provided with a grip bar 33 for easy gripping by the operator. The setting of the connecting column 34 at the top can achieve the purpose of forming a stable downward power arm with the second power arm 121, and the setting of the grip bar 33 can facilitate the subsequent gripping by the operator.

[0035] It should be noted that the bottom of the mounting bracket 11 is provided with a pulley group 13 for moving the jack body 1. The pulley group 13 facilitates the small-range movement of the mounting bracket 11.

[0036] Furthermore, the internal structure of the jack is relatively mature in the existing technology. In this embodiment, the main focus is on improving and solving the problem of the jack's power arm. Therefore, the internal structure of the jack will not be described in detail in this embodiment. Moreover, the 1.5T load capacity also refers to a large load capacity in a broad sense.

[0037] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
