Description

The concealed light path perforate cover assembly structure of opaque projector

Technical field

It the utility model is related to projector equipment field, more particularly to a kind of concealed light path perforate upper cover of opaque projector Modular construction.

Background technology

With the development in pluralism of projection-type product, the fast development of particularly ultrashort in recent years burnt laser projection, throws Shadow class product progressively consumes transition from the commercial consumption of traditional engineering to home theater, it is desirable to which product structure appearance more fashion is bright Beautiful, simplicity generosity.

Since opaque projector opens up because light path need to be covered on product light path perforate and avoids light path pit, on plastic cement Box cover die is molded and final assembly reason, and product light path perforate before this and the dimple size design of avoidance light path are bigger, and entirely It is exposed outside, influence product beauty.

Utility model content

To overcome existing opaque projector upper cover to influence appearance since the reasons such as mould molding cause structure size larger The deficiencies of, technical problem to be solved in the utility model is：A kind of more reasonable structure is provided, makes simpler reflective throwing The concealed light path perforate cover assembly structure of shadow machine.

Technical solution is used by the utility model solves its technical problem：

The concealed light path perforate cover assembly structure of opaque projector, including assemble successively upper cover, decoration and under Lid, the upper tops are equipped with inside sunk structure, and the side of the sunk structure is equipped with the light path perforate for penetrating upper cover, institute It is 50~80 ° that the direction of light path perforate, which is stated, with the angle of upper cover axis direction.

It is further that the direction of the light path perforate and the angle of upper cover axis direction are 60 °.

It is further that the upper cover periphery is uniformly provided with multiple limit ribs and buckle, the limit rib and buckle are mutual It is arranged at intervals, the top perimeter of the decoration is equipped with the limiting slot and card slot adaptable with limit rib and buckle.

It is further that the limit rib and buckle are outward-dipping structure, both angles with upper cover axis are 5 ~10 °.

It is further that chromium plating or spray-painting and decorating have been done in the outer surface of the decoration.

It is further that the bottom periphery of the decoration is uniformly provided with multiple lock housing screw poles, and the decoration is with Lid is realized by the cooperation of the screw through lower tops and lock housing screw pole and connected.

The beneficial effects of the utility model are：The structure type assembled using upper cover, decoration and lower cover, Neng Goutong When meet optical path direction walks mould and mould is walked in complete machine packaging technology direction requirement, upper cover ensures while concealed type optical port is realized The appearance of product fineness and moulding, improve the class of projection products, and decoration can be easy to peace while meeting beautiful Cap assemblies are loaded onto, effectively reduce mould development difficulty, improve the production efficiency and quality of product.

Embodiment

The utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1, the concealed light path perforate cover assembly structure of the opaque projector of the utility model, including successively Upper cover 1, decoration 2 and the lower cover 3 of assembling, the top of upper cover 1 are equipped with inside sunk structure 11, the sunk structure 11 Side, which is equipped with, penetrates the light path perforate 12 of upper cover 1, and the direction of the light path perforate 12 and the angle of 1 axis direction of upper cover be 50~ 80°.Existing superstructure is to be integrally formed making by mould mostly, and in order to meet that mould molds demand, some light paths are opened Hole directly make it is exposed, its direction and upper cover it is overall to walk mould direction consistent；Some employ concealed light path perforate, but will Mould direction is walked in view of entirety, causes the deficiencies of mould structure is complicated, and cost of manufacture is high.

The utility model is directed to above-mentioned deficiency, by the structure that superstructure is divided into upper cover 1, decoration 2 is mutually assembled with lower cover 3 Form, wherein upper cover 1 walk mould direction and can make, i.e., folder with upper cover 1 axis direction consistent with the direction of light path perforate 11 Angle is 50~80 °, and decoration 2 and lower cover 3 can be then used perpendicular or parallel to the direction of its axis into walking mould, so divided Open and make and then the mode assembled again, can substantially reduce exploitation and the use cost of mould, and obtained product is also more Add exquisiteness.

Walk that mould direction is consistent with the direction of light path perforate 11, and light path perforate 11 can make more due to upper cover 1 Add it is accurate, can be with when the direction of the light path perforate 11 and the angle of 1 axis direction of upper cover are 60 ° according to experiment and analysis Obtain optimal using effect.

Upper cover 1 and the assembling of decoration 2 can take various forms, for example be threadedly coupled, be interference fitted etc., but for letter Change production process and ensure the reliability of connection, the utility model employs the connection mode of engaging, specifically such as Fig. 2, Fig. 3 institute Show, multiple limit ribs 13 and buckle 14 are uniformly provided with 1 periphery of upper cover, and the limit rib 13 and buckle 14 spaced are set Put, the top perimeter of the decoration 2 is equipped with the limiting slots 21 and card slot 22 being adapted with limit rib 13 and buckle 14, as Fig. 4, Shown in Fig. 5.Limit rib 13 and limiting slot 21 play the role of positioning, and buckle 14 realizes close connection with card slot 22.

During actual fabrication, it is also necessary to the mated condition of upper cover 1 and 2 edge of decoration is considered, in order to reduce both The gap of assembling, outward-dipping structure type is disposed as by the limit rib 13 and buckle 14, both and 1 axis of upper cover Angle is 5~10 °.Using inclined dress mode, it can coordinate both even closer, so as to improve the globality of product.

In addition, in order to improve the aesthetics of whole cover assembly, can be done in the outer surface of decoration 2 chromium plating or paint into Luggage is adornd.

Similar with upper cover 1 and the assembling of decoration 2, decoration 2 and the assembling of lower cover 3 can also take various forms, For example be threadedly coupled, engage etc., the utility model employs screw connecting mode, because the cooperation of both needs more firm one A bit, so the concrete structure used is as shown in figure 4, the bottom periphery in the decoration 2 is uniformly provided with multiple lock housing screw poles 23, the decoration 2 is with lower cover 3 by realizing and connecting through the screw at the top of lower cover 3 and the cooperation of lock housing screw pole 23.

The utility model uses the structure type that upper cover, decoration and lower cover are assembled, and can meet light path side at the same time To walking mould and the requirement of mould is walked in complete machine packaging technology direction, upper cover ensure that product is exquisite while concealed type optical port is realized Appearance and moulding, improve the class of projection products, and decoration can be easily installed cover assembly while meeting beautiful, have Effect reduces mould development difficulty, improves the production efficiency and quality of product.
