Problems solved by technology

[0003] At present, the commonly used support rods are generally wooden or metal rods. Wooden rods have a relatively small bearing capacity and are generally used as temporary support rods, while metal rods are heavy; both wooden and metal rods are generally non-stretchable and cannot The height of the supported object is adapted to the height of the supported object through the length of the telescopic rod body. In general, only the length of the wooden or metal rod is cut to adapt to the height of the supported object. Therefore, it is more troublesome in actual work; currently, jacks are used for support. , add one or more supporting objects to the jack for support when in use
If you choose a support to support on the jack, then the height of the support must be suitable for the height of the support. Generally, you can only intercept the length of the support. This method is time-consuming and laborious; if you choose multiple supports to be superimposed on the jack support on the ground, leaving potential safety hazards in actual production or disaster relief. In summary, the supporting methods of the existing technical problems cannot be implemented quickly and effectively, especially in disaster relief, this technical defect is more prominent

example 1

[0045] Example 1: Such as Figure 1 to Figure 22 The telescopic support rod includes an outer sleeve body 1 and an inner sleeve body 2. The outer sleeve body 1 is equipped with an inner sleeve body 2; the outer sleeve body 1 has an outer sleeve cavity 1-2; The outer sleeve cavity 1-2 has internal tooth-shaped protrusions 1-1; the inner tooth-shaped protrusion 1-1 includes the inner horizontal direction of the outer sleeve cavity 1-2 More than two segments of "inner teeth" with inner arc shapes; the outer whole body of the inner sleeve body 2 is uniformly parallel with outer tooth-shaped protrusions 2-1; the outer tooth-shaped protrusions 2-1 include Two or more segments of "outer teeth" with outer arcs arranged in the horizontal direction outside the inner casing body 2;

[0046] The inner tooth-shaped protrusion 1-1 of the outer sleeve body 1 and the outer tooth-shaped protrusion 2-1 of the inner sleeve body 2 cooperate with each other to form a telescopic support rod;

[0047] ...

example 2

[0063] Example 2: Such as Figure 1 to Figure 22 According to the telescopic support rod described in Example 1, the upper section inside the outer sleeve cavity 1-2 has uniformly parallel distributed internal tooth-shaped protrusions 1-1, and the internal tooth-shaped protrusions 1-1 The lower part is a hollow straight tube, or the inside of the outer sleeve cavity 1-2 is uniformly distributed with internal tooth-shaped protrusions 1-1 in parallel.

example 3

[0064] Example 3: Such as Figure 1 to Figure 22 According to a telescopic support rod according to example 1 or 2, the middle part of the "external teeth" has a positioning groove 7; the outer sleeve body 1 also includes a safety lock, which is installed on the outer sleeve body The side of the upper section of 1; the safety buckle lock also includes a positioning thimble 6-1, an elastic body 6, the inner elastic body 6 of the safety buckle lock will spring the thimble 6-1 inward, and the inner teeth protrude 1- When 1 and the external tooth-shaped protrusion 1-2 rotate and overlap, the thimble 6-1 is locked into the positioning slot 7;

[0065] The elastic body 6 is a spring, a plastic elastic body or an elastic sheet; further, the safety buckle lock is replaced by a tightening screw.

Abstract

The invention discloses a telescopic supporting rod. The telescopic supporting rod is used for common temporary supporting, semi-permanent or permanent supporting, in particular to rapid supporting in the field of emergency rescue and disaster relief. The supporting rod adapts to the height of a supported object through rapid telescoping and comprises an outer casing pipe body and an inner casing pipe body. Two sets of tooth-shaped protrusions are arranged in the outer casing pipe body, and two sets of tooth-shaped protrusions are arranged in the inner casing pipe body. The tooth-shaped protrusions of the outer casing pipe body are matched with the tooth-shaped protrusions of the inner casing pipe body, a jack is used for adjusting the height, and the installation speed is high. A general worker can directly perform the installation operation skillfully, the load-bearing capacity of the supporting rod is large, common temporary supporting is achieved, and the supporting rod can also be used for semi-permanent or permanent supporting to achieve the purposes of rapid supporting, stable supporting, high safety, high load-bearing capacity and simple operation. The advantages are especially outstanding for the situations such as emergency rescue and disaster relief having high requirement for the speed and safety.

Description

Technical field [0001] The invention relates to a telescopic support rod, which is used for general temporary support, semi-permanent or permanent support, and is especially suitable for rapid support in the field of emergency rescue and disaster relief. Background technique [0002] In daily life, especially in the field of industrial installation or emergency rescue and disaster relief, support rods that support heavy objects are often used to support and strengthen objects. According to the use time of support rods, they are generally divided into three types: 1. Temporary Support, a temporary support rod that is removed immediately after the support is completed; 2. A semi-permanent support rod that can be removed with a certain service life after support is reinforced; 3. A permanent support rod that is reinforced after support and is not removed. [0003] At present, the commonly used support poles are generally wooden poles or metal poles. The bearing capacity of wooden pole...
