Description

Technical Field

[0001] The utility model relates to the technical field of CO2 analyzers, in particular to a portable infrared CO2 analyzer. Background Art

[0002] Infrared CO2 analyzers are devices used to measure carbon dioxide concentration in the environment and have a wide range of applications. In some scenarios, frequent or short-term measurements are often required at multiple locations. However, existing non-stationary analyzers are inconvenient to move and are prone to collisions with other objects during movement.

[0003] To this end, Chinese patent CN220542777U discloses a portable infrared CO and CO2 analyzer for sanitary testing. The analyzer has a retractable handle on the top. When you need to take something, you only need to pull the rod and the handle, freeing one hand to take other items, greatly improving work efficiency.

[0004] However, lifting the analyzer by the handle requires overcoming gravity, and lifting the entire analyzer is still quite laborious. This is especially true when conducting short-term measurements at multiple locations, which requires frequent movement of the analyzer. Because the handle is fixed and requires the operator to lift the analyzer with one hand, it can be difficult to immediately grasp the handle if the analyzer is large. After grasping the handle, if there is a large gap between the handle and the body, lifting the analyzer becomes even more difficult. Utility Model Content

[0005] In order to solve the above problems, a portable infrared CO2 analyzer is provided. The chassis, movable handle and fixing mechanism are used to solve the problem that the operator cannot flexibly grasp the handle when moving the traditional analyzer.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1 and Figure 2 : A portable infrared CO2 analyzer includes a chassis 1, a movable handle 2 and a fixing mechanism 3; two mounting bars 11 are provided on the chassis 1, and a universal wheel 12 is provided at the bottom of the chassis 1; a connecting piece 21 is provided on both sides of the movable handle 2, and the two connecting pieces 21 are respectively slidably engaged with the two mounting bars 11; the fixing mechanism 3 is used to fix the connecting piece 21 to the mounting bar 11.

[0026] The present invention realizes the function of flexibly adjusting the position of the handle through the chassis 1, the movable handle 2 and the fixing mechanism 3. In conjunction with the universal wheel 12 at the bottom of the chassis 1, on a flat ground, the operator can directly pull the movable handle 2 to move the position of the analyzer after adjusting the position of the movable handle 2. The operator can move the analyzer in a more portable and labor-saving manner, which solves the problem that the operator cannot flexibly grasp the handle when moving the traditional analyzer. When moving the analyzer, the operator first releases the fixation of the connecting member 21 by the fixing mechanism 3, and then pulls the movable handle 2 to adjust the position of the movable handle 2. After the adjustment is completed, the operator fixes the connecting member 21 through the fixing mechanism 3. Then, the operator pulls the movable handle 2, transmits the pulling force to the chassis 1 through the movable handle 2 and the connecting member 21, and then moves the chassis 1 by rolling the universal wheel 12, thereby driving the analyzer to move quickly.

[0027] Reference Figure 1 and Figure 2 : A guide groove 111 is provided on the mounting bar 11, and the guide groove 111 extends along the extension direction of the mounting bar 11; a slider 211 is provided at one end of the connecting member 21 close to the mounting bar 11, which slides with the guide groove 111; a guide rod 22 is connected to the connecting member 21, and the guide rod 22 connects the two connecting members 21.

[0028] The present invention stabilizes the connection between the connector 21 and the mounting bar 11 through the guide groove 111, the slider 211, and the guide rod 22. The guide groove 111 and the slider 211 cooperate to guide and support the sliding of the connector 21 and the movable handle 2. Furthermore, the connection of the guide rod 22 further enhances the overall structural strength of the movable handle 2, allowing the operator to lift the entire analyzer by hand.

[0029] Reference Figure 2 and Figure 3 : The slider 211 is a cylinder.

[0030] As a first embodiment of the present invention, by configuring the slider 211 as a cylinder, the sliding flexibility of the connector 21 is further improved, allowing the connector 21 to slide smoothly relative to the mounting bar 11. When the analyzer is moved by pulling the movable handle 2, there is no need to secure the connector 21 with the fixing mechanism 3. During movement, the operator can rotate the connector 21 and the movable handle 2 around the axis of the slider 211 to adjust the pulling angle. This allows the operator to move the analyzer more comfortably and with less effort.

[0031] Reference Figure 4 : The slider 211 is a cuboid.

[0032] As a second embodiment of the present invention, by configuring the slider 211 as a rectangular parallelepiped to restrict the rotation of the connecting member 21, the operator can more stably adjust the position of the movable handle 2 by pushing or pulling the movable handle 2. Because the slider 211 is a rectangular parallelepiped, the sliding engagement between the slider 211 and the guide groove 111 maintains the connecting member 21 in a vertical position. Therefore, regardless of the position of the movable handle 2, the operator can still adjust the position of the movable handle 2 with relative stability.

[0033] Reference Figure 1 and Figure 5 : At least three positioning grooves 112 are provided on the mounting bar 11, and the multiple positioning grooves 112 are equidistantly distributed along the extension direction of the mounting bar 11; the fixing mechanism 3 includes a connecting block 31 and a telescopic rod 32; the connecting block 31 is connected to the movable handle 2, and a positioning block 311 is provided on the connecting block 31 for cooperating with the positioning groove 112. When the positioning block 311 is plugged into the positioning groove 112, the connecting block 31 is restricted from sliding along the extension direction of the mounting bar 11; the telescopic rod 32 includes a main rod and a sub-rod, the main rod and the sub-rod are slidably matched, and the main rod and the sub-rod are respectively connected to the connecting block 31 and the connecting member 21; an elastic member 321 is provided on the telescopic rod 32, and the two ends of the elastic member 321 are respectively connected to the main rod and the sub-rod.

[0034] The present invention secures the connector 21 to the mounting bar 11 through the connection block 31, telescopic rod 32, and positioning slot 112. When the operator lifts the movable handle 2, the connection block 31 is pressed against the mounting bar 11 by the elastic force of the elastic member 321. When the positioning block 311 aligns with the positioning slot 112, the two engage. If the vertical upward force generated by the operator pulling the movable handle 2 is insufficient to disengage the positioning block 311 from the positioning slot 112, the engagement of the positioning block 311 with the positioning slot 112 prevents the connector 21 from sliding along the extension direction of the mounting bar 11, thereby enabling stable pulling or pushing of the analyzer.

[0035] Reference Figure 6 and Figure 7 : A supporting assembly 13 for supporting the chassis 1 is provided at the bottom of the chassis 1, and the supporting assembly 13 includes a supporting frame 131 and a magnetic block 132; the supporting frame 131 is rotatably set on the chassis 1, and a long slot is opened on the supporting frame 131; the magnetic block 132 is set at the bottom of the chassis 1, and a metal strip that cooperates with the magnetic block 132 is provided in the long slot of the supporting frame 131. When the supporting frame 131 is in a folded state, the magnetic block 132 is plugged into the long slot, and the magnetic block 132 absorbs the metal strip.

[0036] The hinged end of the support frame 131 is set at a right angle on the side away from the magnetic block 132. When the support frame 131 is rotated to a vertical state, the rotation angle of the support frame 131 is limited by the cooperation between the right angle and the bottom wall of the chassis 1. A bottom plate 1311 is provided at the end of the support frame 131 away from the hinge point. When using the analyzer, the support frame 131 is rotated so that the bottom plate 1311 of the support frame 131 contacts the ground to provide stable support, thereby avoiding the situation where the analyzer is moved due to accidental touch by the operator. When moving the support frame 131, the support frame 131 is folded, and the magnetic block 132 is used to absorb the metal strip in the long groove of the support frame 131 to fix the support frame 131, so as to avoid the resistance generated by the friction between the support frame 131 and the ground affecting the movement of the analyzer.

[0037] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
