Description

Technical Field

[0001] The present invention relates to the technical field related to measuring equipment, and in particular to a level meter with an anti-collision function. Background Art

[0002] Laser level is a level measurement and calibration device required in the measurement process of modern construction. With the maturity of laser level technology, the level measurement and calibration accuracy and efficiency of laser level are gradually improved. The application of laser level can achieve more accurate level measurement and reference, which greatly improves the level measurement and planning efficiency of contemporary construction engineering. In the prior art, the use of laser level usually needs to be matched with the bottom support so that it can be placed on the construction site for measurement. However, the existing laser level body still has the following defects:

[0003] 1. With the continuous development of materials and housings, laser levels have been optimized in terms of protection and drop resistance, reducing the probability of drop damage. However, the laser levels in the existing technology do not have anti-collision functions. In the actual construction measurement and calibration process, the laser level needs to be placed in the site for a long time, and the construction site often needs to move around and work, which inevitably leads to collisions with the laser level. The collision will cause the level to be unbalanced, tip over, and the calibration level function to be offset;

[0004] 2. The existing laser level support base usually adopts multiple feet with pointed tips, so that it can be supported and has a certain fixing effect. It is set up at the construction site for use. However, when a collision occurs during the operation, the fixing effect of the tip of the foot relative to the ground fulcrum makes it directly act as a fulcrum when a collision occurs. The collision force causes the level body to flip and fall to the ground, causing the measurement operation to be suspended and there is a problem of collision damage;

[0005] 3. When the laser level is set up during the construction process, when there is a bump due to construction and personnel movement, there will be problems such as position displacement and body tipping, causing the operation to be suspended. The existing laser level does not have the function of dealing with collisions. At the same time, when a collision occurs, it cannot realize automatic reset and correction functions, and additional reset and recalibration are required, which greatly affects the actual use efficiency and measurement effect.

[0018] Beneficial effects of the present invention:

[0019] A collision protection function component is provided in a level with an anti-collision function of the present invention. During the horizontal calibration and measurement operation, the support ring seat is set in the operation scene, and the battery module is energized to start the transmission electromagnet, driving the magnetic hemisphere to bounce upward and fit the inner wall of the top cavity of the embedded sphere, so that the magnetic hemisphere interacts with each magnetic matching arc piece, so that the magnetic matching arc piece moves back, and the air pressure in the rear airbag is promoted to pass through the conductive gas groove, the air pressure conductive cavity, the gas transmission conduit, and the pneumatic inner cavity, and then the pneumatic slide bar is ejected, and the protective arc plate is pushed to slide out of the protective embedded groove. After sliding out, the protective arc rod slides out from the side end opening of the protective embedded slide groove under the interaction of the protective sliding end block and the push long spring, thereby forming a surrounding protection effect on the outer wall of the level housing, and the flexible support pad faces the outer wall of the level housing, so that the overall elastic buffering effect of the protective arc plate brought by the pneumatic slide bar and the spring assembly and the surrounding protection effect of each group of protective arc rods on the outer side of the level housing can achieve the problem of avoiding the body from being hit, sideways tipping and damage during the operation.

[0020] The spirit level with anti-collision function of the present invention is provided with a function of reducing collision effect and hidden danger. When the battery module is energized, the transmission electromagnet is started, driving the magnetic hemisphere to bounce upward and fit against the inner wall of the top cavity of the embedded sphere, so that the magnetic hemisphere interacts with each magnetic matching arc piece, so that the magnetic matching arc piece moves back, so that the pneumatic transmission forms a surrounding protection function. At the same time, the damping fitting film cancels the fitting damping fixing effect on the outer wall of the embedded sphere. At the same time, the magnetic isotropic repulsion effect makes the magnetic dome piece and each magnetic matching arc piece interact with the magnetic hemisphere, so that the whole housing of the spirit level produces a slight upward suspension function through the repulsion effect of the magnetic matching base and the magnetic hemisphere, and makes each body support foot leave the ground, so that when the housing of the spirit level is hit, it is first buffered by the surrounding protection function and the fuselage is protected. The suspension effect of the magnetic support will first make the body support feet leave the ground to avoid collision problems. The fixing effect of the support foot tip relative to the ground support point will directly serve as a support point in the event of a collision, and cooperate with the collision force to cause the level body to flip over and knock to the ground, so that the measurement operation is suspended and there is a problem of collision damage. At the same time, through the suspension effect of the magnetic force, the counterweight parts in the support ring seat, the functional support rod and the support slide rod effect, and the bottom is ejected through the transmission support shaft so that the drag reduction bottom plate is attached to the ground by the sliding balls to reduce the sliding resistance, it can be achieved that the collision force will only drive the overall lateral sliding of the level housing and produce appropriate deflection around the embedded sphere to reduce the force, so that the body support foot support reduces the turning force of the support point, and then under the effect of the support ring seat counterweight parts, it can avoid the problem of tipping over and the potential risk of tipping over.

[0021] In a spirit level with anti-collision function of the present invention, the functional structure of the anti-collision support base and the spirit level body can not only realize collision protection, collision reduction effect and hidden danger function, but also realize automatic reset effect after collision offset. Through the principle of magnetic homogeneity repulsion, the circumferential array distribution of each group of magnetic matching arc pieces and the magnetic dome piece on the top will form a stable magnetic repulsion effect relative to the magnetic hemisphere, so that the magnetic dome piece and each magnetic matching arc piece and the magnetic hemisphere interact with each other, so that the whole housing of the spirit level produces a slight upward suspension function through the repulsion effect of the magnetic matching base and the magnetic hemisphere. Therefore, after a collision, through the stable The magnetic repulsion effect will keep the level housing vertically upward. At the same time, the lateral force generated by the collision will cause the rod base to slide and buffer in the support ring seat, and the support ring seat will not move under the effect of the counterweight, so that the rod base can slide and buffer within a certain range through the deflection and sliding of the support slide bar. After the collision, through the installation of the torsion spring assembly of the shaft, the magnetic end block at the end of the support slide bar, and the repulsion of the magnetic end piece and the support spring support, each group of support slide bars are reset and the rod base is pushed back to the center position, thereby realizing collision protection, reducing collision effects and hidden dangers, and achieving the automatic reset function after collision offset.

The laser source in the level host 27 is started through the transistor, amplifier and other components to release the horizontal laser from the laser transmitter head control knob 12 to achieve high-precision measurement operations;

[0048] In the present invention, a collision protection function component is provided in a level with an anti-collision function. During the level calibration and measurement operation, the support ring seat 40 is set in the operation scene, and the battery module 62 is energized to start the transmission electromagnet 64, driving the magnetic hemisphere 68 to bounce upward and fit the inner wall of the top cavity of the embedded sphere 54, so that the magnetic hemisphere 68 interacts with each magnetic matching arc piece 97, so that the magnetic matching arc piece 97 moves back, pushing the air pressure in the rear airbag 94 to pass through the conductive air groove 99, the air pressure conductive cavity 88, the air conductive conduit 82, and the pneumatic inner cavity 80, and then the pneumatic slide rod 84 pops up, pushing the protective arc plate 20 to slide out of the protective embedded groove 19.

At the same time, the flexible support pad 74 faces the outer wall of the level housing 11, so that the overall elastic buffering effect of the protective arc plate 20 brought by the pneumatic slide rod 84 and the spring assembly and the surrounding protection effect of each group of protective arc rods 73 on the outer side of the level housing 11 can achieve the problem of avoiding collision, side tipping damage and other problems of the machine body during operation;

[0049] In a level with an anti-collision function of the present invention, a function of reducing collision effects and hidden dangers is provided. When the battery module 62 is energized, the transmission electromagnet 64 is started, driving the magnetic hemisphere 68 to bounce upward and fit against the inner wall of the top cavity of the embedded sphere 54, so that the magnetic hemisphere 68 interacts with each magnetic matching arc piece 97, so that the magnetic matching arc piece 97 moves back, so that the pneumatic transmission forms a surrounding protection function. At the same time, the damping fitting film 92 cancels the fitting damping fixing effect on the outer wall of the embedded sphere 54. At the same time, the magnetic isotropic repulsion effect makes the magnetic dome sheet 91 and each magnetic matching arc piece 97 interact with the magnetic hemisphere 68, so that the level housing 11 as a whole produces a slight upward suspension function through the repulsion effect of the magnetic matching base 89 and the magnetic hemisphere 68, and makes each body support foot 16 leave the ground, so that when the level housing 11 is hit, it is first buffered by the surrounding protection function and the machine is The body is protected and the suspension effect of magnetic support will first make the body support foot 16 leave the ground to avoid collision problems. The fixing effect of the support foot tip relative to the ground support point makes it directly act as a support point when a collision occurs, and cooperate with the collision force to make the level meter body flip over and knock to the ground, so that the measurement operation is terminated and there is a problem of collision damage. At the same time, through the suspension effect of magnetic force and the counterweight in the support ring seat 40 and the functional support rod 53 cooperate with the support slide bar 46 effect, and the bottom is ejected through the transmission support shaft 67 so that the drag reduction bottom plate 70 is attached to the ground by each sliding ball 71 to reduce the sliding resistance, it can be achieved that the collision force will only drive the overall lateral sliding of the level meter housing 11 and generate appropriate deflection around the embedded ball 54 to reduce the force, so that the body support foot 16 supports and reduces the turning force of the support point, and then under the effect of the counterweight of the support ring seat 40, it is possible to avoid tipping and the potential tipping problem;

[0050] In a level with anti-collision function of the present invention, the functional structure setting of the anti-collision support base 10 and the level body 15 can not only realize collision protection, collision reduction effect and hidden danger function, but also realize automatic reset effect after collision offset. Through the principle of magnetic homogeneity repulsion, the circumferential array distribution of each group of magnetic matching arc pieces 97 cooperates with the magnetic dome piece 91 on the top to form a stable magnetic repulsion effect relative to the magnetic hemisphere 68, so that the magnetic dome piece 91 and each magnetic matching arc piece 97 interact with the magnetic hemisphere 68 to make the level housing 11 as a whole produce a slight upward suspension function through the repulsion effect of the magnetic matching base 89 and the magnetic hemisphere 68. Therefore, after the collision, through the stable magnetic force The repulsion effect will keep the level housing 11 vertically upward, and at the same time, the lateral force generated by the collision will cause the rod base 51 to slide and buffer in the support ring seat 40, and the support ring seat 40 will not move under the effect of the counterweight, so that the rod base 51 can slide and buffer within a certain range through the deflection and sliding of the support slide bar 46. After the collision, through the torsion spring assembly of the installed shaft 59, the magnetic end block 55 at the end of the support slide bar 46, and the repulsion of the magnetic end piece 56 and the support of the support spring 57, each group of support slide bars 46 is reset and the rod base 51 is pushed back to the center position, thereby realizing collision protection, reducing collision effects and hidden dangers, and achieving the automatic reset function after collision offset.
