Abstract
The utility model discloses a kind of air draft spiral case, comprise snail plate and snail lid, described snail plate comprises substrate and is vertical at the deflector on substrate, the lateral surface of described deflector is provided with the reinforcement being vertically connected to substrate, the lateral surface of deflector is also provided with some spiral shell seats, described snail lid comprises end plate and is vertical at the side plate with deflector form fit on end plate, the outer ledge of described side plate is provided with the screw corresponding with described spiral shell seat, and described snail lid passes through through screw with snail plate and the screw be locked on spiral shell seat is fixedly connected with.The utility model is only combined by two parts, combines simple, easy to assembly; The setting position of spiral shell seat and screw is reasonable, connects fastening stable; Set reinforcement can strengthen the intensity connecting position greatly, guarantees that the bulk strength of air draft spiral case is increased, and service life increases.
Description
Technical field
The utility model relates to the ventilation equipment technical field of ordering about air flowing, is specially a kind of air draft spiral case.
Background technology
Often need in refrigeration plant to use air draft spiral case to change wind direction, improve wind loss.Current its spiral case of air-conditioner is on the market all obtained by the mode of combination, and current used worm frame is when combining and not rationally, the structural strength deficiency formed, service life is shorter.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of and combines reasonable, intensity foot, long service life a kind of air draft spiral case.
The utility model is achieved through the following technical solutions:
A kind of air draft spiral case, comprise snail plate and snail lid, described snail plate comprises substrate and is vertical at the deflector on substrate, the lateral surface of described deflector is provided with the reinforcement being vertically connected to substrate, the lateral surface of deflector is also provided with some spiral shell seats, described snail lid comprises end plate and is vertical at the side plate with deflector form fit on end plate, the outer ledge of described side plate is provided with the screw corresponding with described spiral shell seat, and described snail lid passes through through screw with snail plate and the screw be locked on spiral shell seat is fixedly connected with.
As preferred embodiment, described substrate is the square structure with inner chamber.
As preferred embodiment, described snail plate is integrally moulded gained.
As preferred embodiment, described snail lid is integrally moulded gained.
The beneficial effects of the utility model are: the utility model is only combined by two parts, combines simple, easy to assembly; The setting position of spiral shell seat and screw is reasonable, connects fastening stable; Set reinforcement can strengthen the intensity connecting position greatly, guarantees that the bulk strength of air draft spiral case is increased, and service life increases.

Symbol description: 1-snail plate, 2-snail lid, 3-substrate, 4-deflector, 5-reinforcement, 6-spiral shell seat, 7-end plate, 8-side plate, 9-screw.
Detailed description of the invention
With reference to the accompanying drawings and the utility model will be further described in conjunction with the embodiments.
See figures.1.and.2, air draft spiral case of the present utility model forms primarily of snail plate 1 and snail lid 2, and both are assembled by the mode of coupling combination.During practical application, air draft spiral case also needs miscellaneous part is installed further and use, do not repeat them here.
Snail plate 1 utilizes the one-body molded gained of plastic material.Snail plate 1 comprises substrate 3 and deflector 4, and deflector 4 is vertical on substrate 3.Substrate 3 is for having the square structure of inner chamber, and its surrounding is provided with for installing fixing dependency structure, and air draft spiral case utilizes this substrate 3 to carry out installation and fixes.The global shape of deflector 4 is volute, can play good wind-guiding effect during use.The lateral surface of deflector 4 is provided with the reinforcement 5 being vertically connected to substrate 3, and these reinforcements 5 can strengthen the bulk strength of deflector 4 greatly, and when guaranteeing to be connected and fixed with snail lid 2, intensity is enough, can not be out of shape.The lateral surface of deflector 4 is also provided with multiple spiral shell seat 6, is connected and fixed for snail lid 2.
Snail lid 2 utilizes integrally moulded gained.Snail lid 2 comprises end plate 7 and side plate 8, and side plate 8 is vertical on end plate 7, and the shape of side plate 8 is mated with deflector 4.The flow-guiding structure with water conservancy diversion cavity can be formed after snail plate 1 and snail lid 2 combine.The outer ledge of side plate 8 is provided with the screw 9 corresponding with spiral shell seat 6, and during installation, snail lid 2 and snail plate 1 correspondence fasten, and to be locked to spiral shell seat 6 can to realize both are fixing by screw through screw 9.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
