Description
Technical Field
[0001] This utility model relates to the field of detectors, and in particular to a portable combustible gas detector. Background Technology
[0002] Combustible gases are substances that can be ignited and exist in a gaseous state at normal temperature and pressure. Examples include hydrogen, acetylene, ethylene, ammonia, and hydrogen sulfide. Combustible gases possess the general characteristics of gases. A combustible gas consisting of only one component is called a single gas; a mixture of two or more combustible gases is called a mixed combustible gas. When combustible gases are mixed in a certain proportion in a suitable combustion-supporting medium, they can ignite or explode under the action of an ignition source. Combustible gas detectors are detectors that respond to the concentration of single or multiple combustible gases. There are two types of combustible gas detectors: catalytic and infrared optical. Catalytic combustible gas detectors use the change in resistance of a heated refractory platinum wire to determine the concentration of combustible gas.
[0003] When staff carry the combustible gas detector by hand, their fingers may accidentally press the button, making it inconvenient to carry. Utility Model Content

[0022] like Figure 1-4 As shown, a portable combustible gas detector includes a detector body 4. A protective box 1 is provided on the outside of the detector body 4. Two drawer slides 2 are installed side by side inside the protective box 1. Several clamping mechanisms 3 for clamping the detector body 4 are installed on the opposite surfaces of the two drawer slides 2. In this embodiment, two clamping mechanisms 3 are installed on each drawer slide 2. The detector body 4 is a combustible gas detector commonly used in the prior art, which can be obtained by purchase. Its specific structure will not be described in detail here.
[0023] like Figure 2 , 3 As shown, the protective box 1 includes a lower box body 1-1 and an upper box body 1-2. The rear sides of the lower box body 1-1 and the upper box body 1-2 are connected together by a pivot. The front sides of the lower box body 1-1 and the upper box body 1-2 are connected together by a locking assembly 1-4. The drawer slide 2 is installed inside the lower box body 1-1. A handle 1-3 is connected to the top surface of the upper box body 1-2.
[0024] The lower box 1-1 includes a base plate 1-1-1, a left side plate 1-1-2 connected to the left side of the base plate 1-1-1, a lower connecting seat 1-1-3 connected to the rear side of the base plate 1-1-1, and a lock body mounting plate 1-1-4 connected to the center of the front side of the base plate 1-1-1. The locking assembly 1-4 is mounted on the lock body mounting plate 1-1-4. Since the detector body 4 and the clamping mechanism 3 have a certain thickness, a pad is installed on the top surface of the base plate 1-1-1, and the drawer slide rail 2 is installed on the top surface of the pad to ensure that the clamping mechanism 3 and the detector body 4 will not rub against the base plate 1-1-1 during the movement of the detector body 4.
[0025] The upper box 1-2 includes a top plate 1-2-1, a right side plate 1-2-2 connected to the right side of the top plate 1-2-1, an upper connecting seat 1-2-3 connected to the side of the top plate 1-2-1 near the lower connecting seat 1-1-3, the lower connecting seat 1-1-3 and the upper connecting seat 1-2-3 connected together by the pivot, and two locking seats 1-2-4 connected to the side of the top plate 1-2-1 away from the lower connecting seat 1-1-3, with locking holes 1-2-4-1 matching the locking assembly 1-4 on the opposite surfaces of the two locking seats 1-2-4.
[0026] The locking assembly 1-4 includes a locking gear 1-4-1, which is rotatably mounted at the center of the lock body mounting plate 1-1-4. That is, the central axis of the locking gear 1-4-1 is rotatably connected to the lock body mounting plate 1-1-4 through a bearing. Lock blocks 1-4-2 are symmetrically arranged on both sides of the locking gear 1-4-1.
[0027] The locking block 1-4-2 includes a horizontal part and a vertical part that are vertically connected together. A rack 1-4-2-1 that meshes with the locking gear 1-4-1 is connected to the horizontal part. Three locking rods 1-4-2-2 that match the lock hole 1-2-4-1 are connected to the vertical part.
[0028] When the upper box 1-2 covers the lower box 1-1, the locking gear 1-4-1 is rotated. The rotation of the locking gear 1-4-1 causes the racks 1-4-2-1 on both sides to move away from each other, thereby causing the locking rod 1-4-2-2 connected to it to move away from the locking gear 1-4-1. This allows the locking rod 1-4-2-2 to be inserted into the corresponding lock hole 1-2-4-1, thus locking the upper box 1-2 and the lower box 1-1 together.
[0029] like Figure 4As shown, the clamping mechanism 3 includes a first clamping seat 3-1, one end of which is connected to the drawer slide rail 2, and the other end of which is connected to a first clamping plate 3-2. A second clamping seat 3-3 is hinged to the first clamping seat 3-1, and one end of the second clamping seat 3-3 is connected to a second clamping plate 3-4. The second clamping plate 3-4 is positioned opposite to the first clamping plate 3-2. Mounting grooves are provided on the opposite surfaces of the first clamping seat 3-1 and the second clamping seat 3-3. A spring 3-5 is provided between the first clamping seat 3-1 and the second clamping seat 3-3, and both ends of the spring 3-5 are installed in the upper and lower mounting grooves. The second clamping plate 3-4 and the first clamping plate 3-2 are located on the upper and lower sides of the detector body 4, and the detector body 4 is clamped by the second clamping plate 3-4 and the first clamping plate 3-2.
[0030] The usage process of this utility model is as follows:
[0031] First, rotate the locking gear 1-4-1. The rotation of the locking gear 1-4-1 causes the racks 1-4-2-1 on both sides to move closer to each other, thereby causing the locking rod 1-4-2-2 connected to it to move closer to the locking gear 1-4-1. This causes the locking rod 1-4-2-2 to disengage from the corresponding lock hole 1-2-4-1. Then, open the upper box 1-2. After that, pull the detector body 4 to move it to the right. The drawer slide 2 unfolds, thereby moving the detector body 4 to the right side of the lower box 1-1. During the testing process, the lower box 1-1 will not obstruct the detector body 4, facilitating its operation.
[0032] After the test is completed, fold the drawer slide 2 to bring the tester body 4 back into the lower box 1-1, then close the upper box 1-2 and use the locking assembly 1-4 to lock the lower box 1-1 and the upper box 1-2 together. The staff can then carry the tester using the handle 1-3.
[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
