Description

Technical Field

[0001] This utility model belongs to the field of laser level technology, specifically relating to an improved laser level fixing device. Background Technology

[0002] Currently, laser levels used on construction sites generally employ lifting tripods. Their main feature is the presence of a crank mechanism, allowing for maximum precision adjustment of the working height via a handle. At its center is a telescopic tripod with a worm gear; the sliding mechanism allows for adjustment of the entire structure's height. However, this gear-type telescopic mechanism, which controls the up-and-down movement of the central iron core, suffers from instability. It is susceptible to wind and may even automatically slip over time, affecting the accuracy of the level measurement. Furthermore, while the tripod uses a rubber base to increase friction and prevent the machine from accidentally touching or slipping during measurement, it remains unstable in windy conditions.

[0003] The existing technology has the following problems:

[0004] 1. Currently available improved laser level fixing devices on the market are prone to slippage due to wind or even over time, affecting the accuracy of elevation measurement on site. In addition, the rubber base of the tripod increases friction to prevent the machine from touching or slipping during measurement, but it is still unstable in windy conditions. Utility Model Content

[0005] The purpose of this invention is to provide an improved laser level fixing device for existing devices, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an improved laser level fixing device, including a bottom triangular bracket, a middle fixing sleeve welded to the inner ring surface of the bottom triangular bracket, and a magnet that can attract iron blocks fixedly connected to the side surface of the bottom triangular bracket.

[0007] The inner ring surface of the bottom triangular bracket is fitted with an iron core containing an internal electromagnetic coil, the inner ring surface of the middle fixed sleeve is fixedly connected with a gear that controls the up and down movement of the central iron core, and the inner ring surface of the middle fixed sleeve is equipped with a built-in circuit breaker.

[0008] The present invention further illustrates that the bottom surface of the bottom triangular bracket is fitted with anti-slip fixing feet, and the anti-slip fixing feet are arranged around the bottom triangular bracket as the center point.

[0009] The above technical solution, with its anti-slip fixing feet arranged around the bottom triangular bracket as the center point, facilitates stable use and placement of the bottom triangular bracket by the user.

[0010] This utility model further illustrates that a fixing magnet is fixedly connected to the inner ring surface of the middle fixing sleeve, and the fixing magnet is symmetrically arranged with the vertical center line of the bottom triangular bracket as the axis of symmetry.

[0011] Using the above technical solution, the fixed magnets symmetrically arranged with the vertical center line of the bottom triangular bracket as the axis of symmetry can facilitate the user to snap the iron core with the internal electromagnetic coil into place.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] This utility model provides an improved laser level fixing device. The device consists of a fixed component, a movable fixed component, and a magnet for attracting iron blocks. The entire device is made of steel, with a rubber anti-slip base at the bottom. A magnetic attraction device at the bottom of the support increases the device's stability in windy weather. The upper part utilizes the characteristic that an energized electromagnetic coil attracts the magnet, improving the stability of the laser line when the instrument is stationary. This reduces the negative impacts of weather conditions and the automatic sliding of the gears in the control center iron core of traditional laser levels. The design dimensions can be considered to meet the distance requirements of on-site elevation measurements. It can be produced in various sizes, is easy to install and disassemble, reusable, and conforms to green principles. The construction concept of this device is as follows: the fixed component is welded together from a bottom triangular bracket and a central fixed sleeve. The movable fixed component in the middle consists of a movable iron core with an internal electromagnetic coil. The movable iron core with an internal electromagnetic coil is connected to the central fixed sleeve through magnets that can attract iron blocks. An internal circuit breaker and a gear that controls the up-and-down movement of the iron core with an internal electromagnetic coil are installed on the outside of the central fixed sleeve. Two magnets that can attract iron blocks are installed at the bottom of the bottom triangular bracket to meet the user's needs for stable use. Attached Figure Description
