Abstract
A fan case with an inspection window is mainly composed of a machine case, an installation base and a mesh cover, wherein the installation base is arranged on the outer surface of the machine case. Reinforcing ribs are arranged between the two sides of the installation base and the machine case. The left side and the right side of the installation base are provided with a V-shaped groove and the inspection window respectively, and a half-round hole is formed in the lower portion of the V-shaped groove. The mesh cover is arranged inside the machine case and provided with a boss matched with the V-shaped groove in shape and size. According to the fan case, the machine case is provided with the inspection window so that internal conditions of the machine case can be observed conveniently and faults of internal components of the machine case can be observed visually, and maintenance and repair are convenient. In addition, the mesh cover is arranged and matched with the V-shaped groove so that dust can be effectively prevented from entering the machine case, and disassembly is convenient.
Description
Technical field
The utility model relates to a kind of flow blower casing, is specially the flow blower casing with inspection hole.
Background technique
Blower fan is to rely on the mechanical energy of input to improve supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Blower fan is that China is called for short the custom of gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower, compressor and Roots blower, but does not comprise piston compressor isometric(al) formula blower and compressor.Gas compression and gas conveying machinery are to be gas pressure energy and kinetic energy the mechanical switch of rotation, and gas is transferred out.
At present, blower fan is generally with bolt or screw, side plate to be fixedly installed togather, and this casing is dismantled and install pretty troublesome, is difficult for maintenance and repair, and open and close casing all wastes time and energy at every turn.In addition, existing blower fan is to be directly fixed in the casing of hollow a bit, and without any protective housing or protective measure, the fan blade running up can be damaged by external granular dust or hard thing, shortens its working life, the radiating effect of impact to product.
Model utility content
The utility model, according to above-mentioned the deficiencies in the prior art, provides one can conveniently observe fan operation situation and easily detachable flow blower casing.
In order to achieve the above object, the technical solution adopted in the utility model is:
With a flow blower casing for inspection hole, mainly formed by casing, fitting seat and guard, the outer side surface of described casing is provided with a fitting seat, between the both sides of fitting seat and casing, is provided with stiffening rib; The right and left of described fitting seat is respectively equipped with V-shaped groove and inspection hole, and the below of described V-shaped groove is provided with semicircle orifice; Described casing inside is provided with guard, and guard is provided with the boss matching with V-shaped groove shape size.
As preferably, described fitting seat and casing are one-body molded.
As preferably, described guard and casing removably connect.
As preferably, described V-shaped groove can be multiple, and the boss number on guard is determined by V-shaped groove number.
The utility model beneficial effect is: the utility model is provided with inspection hole on casing, can conveniently observe the situation of casing inside, can observe intuitively the fault of casing inner piece, maintains easily and repairs; In addition, the utility model is also provided with guard, and matches with V-shaped groove, can effectively prevent that dust from entering casing, and convenient disassembly.

Fig. 2 is net cover structure schematic diagram of the present utility model;
1-casing, 2-inspection hole, 3-fitting seat, 4-V-shaped groove, 5-stiffening rib, 6-semicircle orifice, 7-guard, 8-boss.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated.
As depicted in figs. 1 and 2, a kind of flow blower casing with inspection hole, is mainly made up of casing, fitting seat and guard, and the outer side surface of described casing is provided with a fitting seat, between the both sides of fitting seat and casing, is provided with stiffening rib; The right and left of described fitting seat is respectively equipped with V-shaped groove and inspection hole, and the below of described V-shaped groove is provided with semicircle orifice; Described casing inside is provided with guard, and guard is provided with the boss matching with V-shaped groove shape size.
Described fitting seat and casing are one-body molded; Described guard and casing removably connect; Described V-shaped groove can be multiple, and the boss number on guard is determined by V-shaped groove number.
Such scheme is preferred embodiment of the utility model, but is not changing under spiritual background of the present utility model, and any improvement of doing, within all dropping on protection domain of the present utility model.
