Utility model content
In view of this, the purpose of this utility model is to provide a kind of dust-proof dome type camera with better dust-proof effect.
For achieving the above object, the utility model provides following technical scheme:
A kind of dust-proof dome type camera, comprise base and be arranged on the hemisphere transparency cover on base, described base and hemisphere transparency cover form enclosure space jointly, video camera module is provided with in described enclosure space, described hemisphere transparency cover comprises hemisphere lid and is arranged on the bulge loop of hemisphere lid end face, described bulge loop and hemisphere lid are wholely set, and the end of described base is provided with the annular recess matched with this bulge loop, and described bulge loop is arranged in this annular recess.
The cross section of described bulge loop is rectangle or square, the external cylindrical surface of described bulge loop is provided with external screw thread, the inner cylinder face of described annular recess is provided with the internal thread matched with this external screw thread, and some blind holes are put in the external cylindrical surface pressed on ring winding of described bulge loop, are filled with active carbon stick in this blind hole.
Sealing ring and the mounting groove for installing sealing circle is provided with bottom described annular recess.
Further, described sealing ring is y-type seal ring, and the opening direction of described y-type seal ring deviates from the direction, axis place of hemisphere transparency cover.
Further, described annular recess medial surface be provided with some dust stratification grooves, described dust stratification groove is arranged on the medial surface corresponding with the inner cylinder face of bulge loop.
Further, described dust stratification groove is ring shaped slot.
Further, described cannelure quantity is 3.
The beneficial effects of the utility model are:
The dust-proof dome type camera structure of one of the present utility model is simple, and be provided with active carbon stick in the threaded connection place of base and hemisphere transparency cover, this active carbon stick has suction-operated to the dust entered in thread pitch, improves dust-proof effect; Meanwhile, the track that dust enters enclosure space is tortuous, further increases dust-proof effect.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of base in Fig. 1;
Fig. 3 is A-A cutaway view in Fig. 1;
Fig. 4 is base and hemisphere transparency cover junction enlarged diagram in Fig. 1.
Wherein: 1-base, 2-hemisphere transparency cover, 3-video camera module, 4-enclosure space, 5-dust stratification groove, 6-sealing ring, 11-annular recess, 21-hemisphere lid, 22-bulge loop, 111-internal thread, 221-external screw thread, 222-active carbon stick.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
The dust-proof dome type camera of one of the present utility model, the hemisphere transparency cover 3 comprising base 1 and be arranged on base 1, described base 1 and hemisphere transparency cover 3 be composition enclosure space 4 jointly, video camera module is provided with in described enclosure space 4, described hemisphere transparency cover 3 comprises hemisphere lid 21 and is arranged on the bulge loop 22 of hemisphere lid 21 end face, described bulge loop 22 is wholely set with hemisphere lid 21, the end of described base 1 is provided with the annular recess 11 matched with this bulge loop 22, and described bulge loop 22 is arranged in this annular recess 11.
The cross section of described bulge loop 22 is rectangle or square, the external cylindrical surface of described bulge loop 22 is provided with external screw thread 221, the inner cylinder face of described annular recess 11 is provided with the internal thread 111 matched with this external screw thread 221, some blind holes are put in the external cylindrical surface pressed on ring winding of described bulge loop 22, are filled with active carbon stick 222 in this blind hole.
Sealing ring 6 and the mounting groove for installing sealing circle 6 is provided with bottom described annular recess 11.
In the present embodiment, dust needs first just can be entered in enclosure space 4 by the gap between bulge loop 22 and groove, and the movement locus of dust is tortuous, makes dust not easily enter in enclosure space 4; Because threaded connection place is provided with active carbon stick 222, the dust entering thread pitch place can be made to be adsorbed by active carbon stick 222 in time, improve dust-proof effect; Meanwhile, sealing ring 6 is set between bulge loop 22 and groove and also improves dust-proof effect.
As the improvement of such scheme, described sealing ring 6 is y-type seal ring 6, and the opening direction of described y-type seal ring 6 deviates from the direction, axis place of hemisphere transparency cover 3.In the present embodiment, y-type seal ring 6 can blocks dust enter in enclosure space 4, if do not adsorbed behind dust enters between screw thread gap, is then deposited in the opening of y-type seal ring 6, and the both sides of sealing ring 6 can not be deposited in, better compared with the dust-proof effect of conventional seals circle 6.
As the improvement of such scheme, described annular recess 11 medial surface be provided with some dust stratification grooves 5, described dust stratification groove 5 is arranged on the medial surface corresponding with the inner cylinder face of bulge loop 22.Concrete, this dust stratification groove 5 is cannelure, and the quantity of this cannelure is 3.When dust enters the gap between the inner cylinder face of bulge loop 22 and the inner side ratio of annular recess 11, can not can drop in this dust stratification groove 5 by dust, this dust stratification groove 5 blocks dust can enter seal cavity further, improves dust-proof effect.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
