Description

Technical Field

[0001] The utility model relates to the technical field of laser level test, in particular to an airtightness test structure of a laser level. Background Art

[0002] A laser level is a measuring tool that uses a laser beam to achieve precise horizontal and vertical positioning. This instrument generates a laser beam through an internal laser transmitter, which is refracted by a prism to form a horizontal or vertical line and projected onto the surface to be measured. The laser level contains precision optical and electronic components. If the airtightness of the instrument is not good, dust, moisture or other harmful substances from the outside may enter the instrument, affecting its normal operation and measurement accuracy, and may even cause damage to the components. Therefore, airtightness testing of the laser level can ensure that it can resist the influence of adverse external environments during use and maintain the stability of its performance and the accuracy of measurement.

[0003] However, traditional laser level airtightness test equipment requires operators to have deep professional knowledge and rich experience. They not only need to have a deep understanding of the test principles, but also be able to accurately set equipment parameters and accurately analyze test results. This makes the use of the equipment relatively complicated and increases the difficulty of operation. At the same time, if the operator is unskilled or lacks skills, the accuracy of the test results may be affected, and even the equipment itself may be damaged. Utility Model Content

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] See also Figures 1 to 4 , is a laser level air tightness test structure of an embodiment of the utility model, comprising a bearing assembly 10, and a test assembly 20 installed on the top of the bearing assembly 10; the test assembly 20 is used to dock with a laser level 30 to perform an air tightness test on the inside of the laser level 30. Specifically, an assembly hole 31 is provided in the middle of the bottom surface of the laser level 30, positioning holes 32 are provided on the bottom surface of the laser level 30 on opposite sides corresponding to the assembly hole 31, and air holes 33 are provided on the bottom surface of the laser level 30 on opposite sides corresponding to the assembly hole 31. Among them, the assembly hole 31 and the positioning hole 32 are not connected to the inside of the laser level 30, while the air hole 33 is connected to the inside of the laser level 30, so the air hole 33 can be used to dock with the laser level 30 for air tightness detection.

[0025] The bearing assembly 10 includes a carrier plate 11, a limit block 12 installed on one side of the top surface of the carrier plate 11, a locking rod 13 that can be lifted and lowered and installed in the middle of the carrier plate 11, positioning pins 14 installed on opposite sides of the locking rod 13, pillars 15 connected to the four opposite corners of the bottom surface of the carrier plate 11, and a bottom plate 16 arranged parallel and spaced below the carrier plate 11; the pillars 15 connect the carrier plate 11 and the bottom plate 16 to form a bracket structure.

[0026] The locking rod 13 is matched and connected with the assembly hole 31 , and the positioning pin 14 corresponds to the positioning hole 32 one by one.

[0027] In this embodiment, the locking rod 13 is a hand-tightened bolt. A through hole is provided in the middle of the carrier plate 11, and the through hole is an internal threaded hole, and the through hole is threadedly connected with the locking rod 13. Specifically, the locking rod 13 passes through the carrier plate 11 upward from the top surface of the carrier plate 11 and protrudes beyond the carrier plate 11 to connect the laser level 30, so as to achieve a fixed connection of the laser level 30. At this time, the bottom surface of the laser level 30 abuts the carrier plate 11, and the side surface of the laser level 30 abuts the limit block 12.

[0028] The test assembly 20 includes a sealing plug 21 and an exhaust plug 22 which are escalably mounted on the carrier plate 11 , and an exhaust pipe 23 connected to the end of the exhaust plug 22 ; the exhaust pipe 23 is externally connected to a multifunctional leak detector (not shown).

[0029] The inside of the air extraction plug 22 is provided with an air extraction hole 24 along its length direction, the top of the air extraction hole 24 penetrates the top of the air extraction plug 22, and the bottom of the air extraction hole 24 penetrates the bottom of the air extraction plug 22 and then downwardly connects to the inside of the air extraction pipe 23. The top of the sealing plug 21 is used to protrude beyond the carrier board 11 and insert an air hole 33 of the laser level 30, and the top of the air extraction plug 22 is used to protrude beyond the carrier board 11 and insert another air hole 33 of the laser level 30. At this time, the inside of the laser level 30 is vacuumed by using a multifunctional leak detector and the change of the negative pressure value is observed, so as to accurately judge whether the air tightness of the laser level 30 is intact.

[0030] During the test, the inside of the laser level 30 is evacuated using a multifunctional leak detector and maintained for a period of time, and the negative pressure value displayed by the multifunctional leak detector is observed to see whether it changes. If the negative pressure value does not change, it means that there is no leakage in the vacuum environment of the laser level 30, that is, the air tightness of the laser level 30 is intact. On the contrary, if the negative pressure value decreases, it means that the air in the atmospheric environment has infiltrated into the inside of the laser level 30 through some means, resulting in a decrease in the negative pressure value, which indicates that there is a problem with the air tightness of the laser level 30. This detection method is not only simple and intuitive, but also has high accuracy and reliability. It can effectively detect whether the air tightness of the laser level 30 meets the standard. The entire operation process is simple and clear, and no special skills or training are required, which greatly improves the convenience of detection.

[0031] The above-mentioned laser level air tightness test structure has a simple structure and is easy to use. The sealing plug 21 and the exhaust plug 22 are connected to the two air holes 33 of the laser level 30. A multifunctional leak detector is used to detect the air pressure changes inside the laser level 30, so the air tightness of the laser level 30 can be efficiently detected. The whole operation process is simple and clear, and no special skills or training are required, which greatly improves the convenience of detection.

[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
