[0006] By adopting the above technical solution, the analyzer body is arranged in a protective box, which protects the analyzer body and reduces the probability of damage to the analyzer body caused by external force collision or accidental falling. When the analyzer body needs to be used, the staff opens the box cover and drives the double-headed screw to rotate through the drive assembly. Since the double-headed screw is threadedly connected to the two bottom blocks, the two bottom blocks are slidingly connected to the bottom wall of the protective box, so that the two bottom blocks move closer to each other and drive the two support plates to rise crosswise, so that the mounting plate moves upward and the analyzer body is lifted out of the protective box, which is convenient for the protection and use of the analyzer body.

[0013] Furthermore, a rubber pad is fixed on the upper surface of the mounting plate.

[0014] By adopting the above technical solution, the rubber pad is made of rubber material, and its material surface has a large friction coefficient, which increases the friction force on the surface of the mounting plate and reduces the probability of the analyzer body moving on the mounting plate.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. In the present application, the analyzer body is arranged in a protective box, which protects the analyzer body and reduces the probability of damage to the analyzer body due to collision with external forces or accidental falling.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0025] like Figure 1-4 As shown, an embodiment of the present application discloses a laser gas analyzer, including a protection box 1, a box cover 2, a mounting plate 3, an analyzer body 4, a lifting assembly 5 and a driving assembly 6.

[0026] The protection box 1 is a rectangular box structure, the top of the protection box 1 is open, and the side wall of the protection box 1 is provided with a mounting groove 11. The box cover 2 is a rectangular structure, and the box cover 2 is hinged on the side wall of the protection box 1. The mounting plate 3 is a rectangular plate structure, and the mounting plate 3 is arranged in the protection box 1 and is slidably connected to the inner wall of the protection box 1. The analyzer body 4 is an analyzer body 4 commonly used in the prior art and applicable to the present embodiment, and the analyzer body 4 is arranged on the upper surface of the mounting plate 3.

[0027] The lifting assembly 5 is installed on the protection box 1 and is used to lift the mounting plate 3. The lifting assembly 5 includes a double-headed screw 51, a bottom block 52 and a support plate 53. The double-headed screw 51 is a horizontally arranged rod-shaped structure. The double-headed screw 51 is rotatably connected to the inner wall of the protection box 1. The double-headed screw 51 is provided with two sections of threads with equal pitch and opposite rotation. The bottom block 52 is a rectangular parallelepiped structure. The bottom block 52 is sleeved on the double-headed screw 51 and threadedly connected. The bottom block 52 is slidably connected to the inner bottom wall of the protection box 1. The bottom block 52 is provided with two sections of threads symmetrically arranged on the double-headed screw 51. The support plate 53 is rotatably connected to the upper surface of the bottom block 52. The upper end of the support plate 53 is rotatably connected to the bottom of the mounting plate 3. Two support plates 53 are staggered.

[0028] The driving assembly 6 is mounted on the protection box 1 and is used to drive the double-ended screw 51 to rotate. The driving assembly 6 includes a motor 61, a battery 62, and a controller 63. The motor 61 is fixed to the inner wall of the mounting groove 11, and the output shaft of the motor 61 passes through the fixing groove and is fixed to the end of the double-ended screw 51. The battery 62 is fixed to the inner bottom wall of the mounting groove 11, and the battery 62 is electrically connected to the motor 61. The controller 63 is fixed to the side wall of the protection box 1, and the controller 63 is electrically connected to the motor 61.

[0029] The analyzer body 4 is arranged in the protective box 1, which protects the analyzer body 4 and reduces the probability of damage caused by external force collision or accidental falling of the analyzer body 4. When the analyzer body 4 needs to be used, the staff opens the box cover 2 and controls the motor 61 to start through the controller 63. The battery 62 provides a power source for the drive motor 61. The output shaft of the motor 61 drives the double-headed screw 51 to rotate. Since the double-headed screw 51 is threadedly connected to the two bottom blocks 52, the two bottom blocks 52 are slidingly connected to the bottom wall of the protective box 1, so that the two bottom blocks 52 move closer to each other and drive the two support plates 53 to rise crosswise, so that the mounting plate 3 moves upward and the analyzer body 4 is lifted out of the protective box 1, which is convenient for the protection and use of the analyzer body 4.

[0030] In order to protect the motor 61 and the battery 62, a flared groove 12 is opened at the intersection between the inner wall of the installation groove 11 and the side wall of the protection box 1. A protective plate 7 is screwed in the flared groove 12. The protective plate 7 protects the motor 61 and the battery 62 in the installation groove 11, reduces the probability of damage to the motor 61 and the battery 62 under the action of external force, and facilitates the maintenance of the motor 61 and the battery 62.

[0031] In order to reduce the probability of overheating of the motor 61, a plurality of heat dissipation holes 71 are opened through the side wall of the protection plate 7. The heat dissipated by the motor 61 is discharged through the heat dissipation holes 71, which plays a role in heat dissipation for the motor 61, thereby reducing the probability of the motor 61 overheating and failing to operate normally or even being damaged.

[0032] In order to reduce the probability of the analyzer body 4 moving on the mounting plate 3, a rubber pad 8 is fixed to the upper surface of the mounting plate 3. The rubber pad 8 is made of rubber material, and its material surface has a large friction coefficient, which increases the friction force on the upper surface of the mounting plate 3, thereby reducing the probability of the analyzer body 4 moving on the mounting plate 3.

[0033] The operating principle of a laser gas analyzer in the present embodiment is as follows: the analyzer body 4 is arranged in the protective box 1, and the protective box 1 protects the analyzer body 4, reducing the probability of the analyzer body 4 being damaged by external force collision or accidental falling. When the analyzer body 4 needs to be used, the staff opens the box cover 2 and controls the motor 61 to start through the controller 63. The battery 62 provides a power source for the drive motor 61. The output shaft of the motor 61 drives the double-headed screw 51 to rotate. Since the double-headed screw 51 is threadedly connected to the two bottom blocks 52, the two bottom blocks 52 are slidingly connected to the bottom wall of the protective box 1, so that the two bottom blocks 52 are moved closer to each other, and drive the two support plates 53 to cross and rise, so that the mounting plate 3 moves upward and the analyzer body 4 is lifted out of the protective box 1, which is convenient for the protection and use of the analyzer body 4.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
