Background technique
To great attention, as far back as during the Seventh Five-Year Plan period, national key subjects have been listed in the research work of amorphous silicon semiconductor in to the research and development one of solar cell in China; 85 and during the State's Ninth Five-Year Plan period, China focuses on aspect such as solar energy in large area battery to research and development.In October, 2003; National Development and Reform Committee, the Department of Science and Technology make the development plan of the five-year solar energy resources; Committee of Development and Reform's " bright engineering " 10,000,000,000 yuan of application that are used to advance solar energy generation technology of will raising funds are planned national solar power system total installation of generating capacity in 2015 and are reached 300 megawatts.China has become the maximum manufacturing nation of global photovoltaic product, and China is about to " the new energy development planning " of appearance, and the electric motor power of China's photovoltaic generation is planned to the year two thousand twenty and reaches 20GW, is more than 10 times of original " renewable energy sources medium-term and long-term plans " middle 1.8GW.
Present domestic solar power silicon manufacturing enterprise mainly contains manufacturers such as Luoyang Monocrystalline Silicon Factory, single crystal silicon base, Ningjin, Hebei and Sichuan high eyebrow semi-conducting material factory; Wherein single crystal silicon base in Ningjin, Hebei is solar monocrystalline silicon production base the biggest in the world, accounts for about 25% of world's solar monocrystalline silicon market share.
Increasingly mature along with the photovoltaic industry; Many battery sheets manufacturer has proposed increasingly high requirement to apparatus maintenance and maintenance; In the PECVD operation of giving battery sheet plated film; Need in process cavity, feed reaction gas reaction gas ionization is reached silicon chip film-coated purpose, and the PE quartz tube is the vital part that is used to excite microwave on the ROTH&RAU equipment, because quartzy friability; Therefore easily at work because of receiving that factors such as machinery, vibrations, thermal expansion are damaged, need regularly remove clean and maintenance often because in process cavity, deposit thick silicon nitride even use intact quartz tube; So whether convenient quartz tube is changed has directly determined the needed time of corrective maintenance, quartz tube is to be fixed on microwave through common screw thread dop to connect on the flange at present, and dismounting is loaded down with trivial details, maintenance time is longer.
When using, the utility model only need connect the locking just can realize the quartz tube assembling time of strip spiral chute on the flange with opening through the position-limited nail above the locking head at microwave; In the time of dismounting, only need just can realize dismounting easily with being rotated counterclockwise in the hole on the spanner insertion locking head.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Provide a kind of quick locking microwave to connect flange; Make quartz tube install out-of-dately, only need connect the locking just can realize the quartz tube assembling time of strip spiral chute on the flange with opening through the position-limited nail above the locking head at microwave; In the time of dismounting, only need just can realize dismounting easily with being rotated counterclockwise in the hole on the spanner insertion locking head.
According to the technological scheme that the utility model provides, said quick locking microwave connects flange, comprises that microwave connects flange, is characterized in that: comprise that also locking head, locking head are installed on microwave and connect on the outer sleeve of flange; Locking head is provided with position-limited nail.
Said microwave connects on the outer sleeve of flange and has two spiral chutes, two spiral chutes outside on the sleeve angular array with 180 degree distribute; Two spiral fluted shapes, size are identical; The axis that all connects the inner sleeve of flange with microwave is the center state that descends in the shape of a spiral; And spiral chute is opened a straight trough that is parallel to the axis of inner sleeve at the starting point place, and this straight trough connects the wall thickness of outer sleeve and connects the upper-end surface of outer sleeve; The width of said straight trough is greater than the diameter of position-limited nail.
Said locking head is provided with two groups of position-limited nails, and microwave connects flange and is provided with the tapped hole corresponding with position-limited nail; Said two groups of tapped holes are the angular array distribution of running shaft with 180 degree with the axis of locking head all.
The utlity model has following advantage: the utility model is provided with the bar shaped spiral chute; Position-limited nail is installed on locking head; Make position-limited nail reach bar shaped spiral fluted limit position through the rotational lock head and also fix through the spiral fluted self-lock ability, easy to operate, save time; Simple in structure, be easy to produce.

Embodiment
Shown in Fig. 1-3, the locking microwave connects flange fast, comprises that microwave connects flange 1, also comprises locking head 2, and locking head 2 is installed on microwave and connects on the outer sleeve 13 of flange 1; Locking head 2 is provided with position-limited nail 3.
Said quick locking microwave connects flange, comprises that microwave connects flange 1, draws together locking head 2, and locking head 2 is installed on microwave and connects on the outer sleeve 13 of flange 1; Locking head 2 is provided with position-limited nail 3.
Said microwave connect have on the outer sleeve 13 of flange 1 two spiral chutes, 15, two spiral chutes 15 outside on the sleeve 13 angular array with 180 degree distribute; Shape, the size of two spiral chutes 15 are identical; The axis that all connects the inner sleeve 14 of flange 1 with microwave is the center state that descends in the shape of a spiral; And spiral chute 15 is opened a straight trough that is parallel to the axis of inner sleeve 14 at the starting point place, and this straight trough connects the wall thickness of outer sleeve 13 and connects the upper-end surface of outer sleeve 13; The width of said straight trough is greater than the diameter of position-limited nail 3.
