Description

Technical Field

[0001] This utility model relates to the field of gas particle counter technology, and in particular to a gas particle counter for high-pressure gas analysis. Background Technology

[0002] The working principle of an air particle counter is mainly based on the detection of laser light by an optical sensor. After being scattered by dust particles, the laser light is received by a photosensitive element, generating a pulse signal. This pulse signal is output, amplified, and then processed digitally. By comparing it with a standard particle signal, the comparison result is expressed using different parameters. Specifically, the air particle counter uses a sampling pump to draw in sampled gas. In a laser chamber, the sampled gas is irradiated with a laser. The frequency of the flashes reflected by the particles represents the number of particles, and the intensity of the reflected light represents the particle size. The reflected data is displayed on a screen for easy and intuitive understanding. Gas particle counters are in widespread demand in the market.

[0003] Existing gas particle counters have shortcomings in production and assembly. For example, the display screen assembly and the housing are usually fixed with screws, which often involve multiple screws and affect assembly efficiency. Furthermore, the display screen assembly is a vulnerable part, and disassembly is extremely inconvenient during later maintenance and replacement. Therefore, we propose a gas particle counter for high-pressure gas analysis to solve the above problems. Utility Model Content

[0004] This invention provides a gas particle counter for high-pressure gas analysis, which solves the technical problem of slow production and assembly efficiency of current gas particle counters.

[0005] To solve the above-mentioned technical problems, this utility model provides a gas particle counter for high-pressure gas analysis, including a gas particle counter body, the gas particle counter body also including a housing and a display screen assembly, the housing having an embedding groove, the display screen assembly being fitted into the embedding groove, and an elastic snap-fit ​​component being provided in the embedding groove, the elastic snap-fit ​​component being at least partially fitted into a slot on the display screen assembly.

[0006] Preferably, the elastic locking assembly includes a spring, a locking plate, and a toggle lever. The top of the locking plate is fixedly connected to the spring, and one side of the locking plate is vertically fixedly connected to the toggle lever.

[0007] The above technical solution involves an elastic snap-fit ​​assembly comprising a spring, a snap-fit ​​plate, and a lever. The top of the snap-fit ​​plate is fixedly connected to the spring, and one side of the snap-fit ​​plate is vertically fixedly connected to the lever. By using two fingers to spread the two levers, the levers cause the snap-fit ​​plate to compress the spring, thus snapping the display assembly into the embedded groove. Then, the two fingers are released, and the snap-fit ​​plate, under the elastic force of the spring, is snapped into the slot on the display assembly, thereby enabling the display assembly to be quickly assembled onto the outer casing.

[0008] Preferably, the top and bottom of the embedding groove are provided with a first groove, the outer casing is provided with a second groove that communicates with the first groove, and the elastic snap-fit ​​component is disposed in the first groove and the second groove.

[0009] The above technical solution is adopted: a first groove is provided at the top and bottom of the embedding slot, and a second groove is provided on the outer casing that communicates with the first groove. The elastic snap-fit ​​component is set in the first groove and the second groove, which does not affect the display screen assembly being snapped in the embedding slot.

[0010] Preferably, the spring and the locking plate of the elastic locking assembly are disposed in the first groove, the actuating rod of the elastic locking assembly is disposed in the second groove, and the actuating rod extends at least partially out of the second groove.

[0011] The above technical solution is adopted: the spring and the locking plate of the elastic locking component are set in the first groove, the actuating rod of the elastic locking component is set in the second groove, and the actuating rod extends at least partially outside the second groove, so that two fingers can open the two actuating rods embedded in the groove, which is convenient for installing the display screen assembly.

[0012] Preferably, a guide component is also provided between the embedding slot and the display screen assembly.

[0013] The above technical solution involves a guide component between the embedded slot and the display panel assembly, which improves the engagement efficiency between the display panel assembly and the embedded slot.

[0014] Preferably, the guide assembly includes a guide groove formed at the top of the embedding slot and a guide strip fixed at the top of the display assembly.

[0015] The above technical solution is adopted: by using a guide component including a guide groove opened at the top of the embedding groove and a guide strip fixed at the top of the display assembly, the guide strip is engaged in the guide groove, so that the display assembly can be quickly engaged in the embedding groove on the outer casing.

[0016] Preferably, the guide strip has an inclined guide surface.

[0017] The above technical solution improves the ease of installation of the display screen assembly and the outer casing by using a guide bar with an inclined guide surface.

[0018] Preferably, a positioning baffle is also provided in the embedding groove, and a wire harness through hole is opened in the middle of the positioning baffle.

[0019] The above technical solution is adopted: a positioning baffle is also provided in the embedding groove, so that when the display panel is inserted into the embedding groove, the elastic snap-fit ​​component can be adapted to the position of the slot on the display panel. A wire harness through hole is opened in the middle of the positioning baffle to facilitate the wire harness to pass through.

[0020] Preferably, two elastic snap-fit ​​components are provided and are symmetrically distributed at the top and bottom of the embedding groove.

[0021] By adopting the above technical solution, two flexible snap-fit ​​components are set and symmetrically distributed at the top and bottom of the embedding slot, which can more firmly fix the display assembly.

[0022] Preferably, the depth of the embedding slot is adapted to the thickness of the display assembly.

[0023] The above technical solution is adopted: by matching the depth of the embedding groove with the thickness of the display assembly, the display assembly can be just right in the embedding groove, preventing the display assembly from protruding too much and causing the display assembly to be easily damaged.

[0024] Compared with related technologies, this utility model has the following beneficial effects:

[0025] 1. Compared with traditional gas particle counters, this utility model incorporates an elastic locking component. The gas particle counter body also includes an outer casing and a display screen assembly. The outer casing has an embedding groove, and the display screen assembly is locked in the embedding groove. An elastic locking component is installed in the embedding groove, and the elastic locking component is at least partially locked in the slot on the display screen assembly. During assembly, firstly, two fingers are used to spread open the two levers, which drive the locking plate to compress the spring, thus locking the display screen assembly in the embedding groove. Then, the two fingers are released, and the locking plate is locked in the slot on the display screen assembly under the elastic force of the spring. This allows the display screen assembly to be quickly assembled onto the outer casing. At the same time, it is also easier to disassemble when the display screen assembly is damaged and needs to be replaced or maintained.

[0026] 2. In this utility model, by providing a guide component, a guide groove is opened at the top of the embedding groove and a guide strip is fixed at the top of the display screen assembly. The guide strip is locked in the guide groove, so that the display screen assembly can be quickly locked into the embedding groove on the outer casing. Attached Figure Description
