The utility model has the advantages of it is following and effect: the adoption sets up the location arch at the pipe cap inner wall, set up on the tube socket with the protruding assorted constant head tank in location has reached the connected mode of simple and convenient pipe cap and tube socket, can enough make pipe cap and tube socket firm connection, the effect of convenient dismantlement again.

Description

A kind of laser diode

Technical field

This utility model is related to fields of light devices, more particularly to a kind of laser diode.

Background technology

At present, the Chinese patent for having a notification number to be CN204732673U on market, which discloses a kind of laser Diode package pipe, including laser tube seat and package cover, are integrated with laser diode on laser tube seat, integrated filtering in package cover It is riveted together with laser tube in piece, package cover.

Although the patent simple structure, it is possible to use encapsulation makes laser module, both can effectively reach diminution and make and swash The volume of light module, can also be effectively increased the heat conductivility of laser diode package pipe.But, laser tube seat and package cover are logical The mode for crossing riveting connects, it has not been convenient to change package cover.

Utility model content

The purpose of this utility model is to provide a kind of not only fixation but also the laser diode of convenient dismounting.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of laser diode, including pipe cap and base, the pipe cap is coaxially arranged with for the saturating of focused laser beam Mirror, is integrated with laser chip on the base, the pipe cap inwall is provided with the positioning convex by made by silastic material, the pipe The inwall of seat is provided with for the locating slot of clamping positioning convex.

By adopting above-mentioned technical proposal, during pipe cap and base clamping, the convex by made by silastic material Rising can occur certain deformation, and then positioning convex is smoothly entered to locating slot, will be of the prior art Pipe cap and the mode of base riveting make into by way of the locating slot clamping on positioning convex and base on pipe cap, both easy Pipe cap and the connected mode of base, cause pipe cap more to have mobility with the connection of base again, can be according to specific needs Arbitrarily collocation pipe cap and base, convenient to dismantle；But will not be that the connection of pipe cap and base becomes gender gap, affect laser diode Normally use.

Further, the positioning convex is arranged in pipe cap inwall in bulge loop, the positioning corresponding with the positioning convex Groove is arranged in scrobicular ring.

By adopting above-mentioned technical proposal, arranging bulge loop on pipe cap can increase the structural strength of pipe cap, again can be with The scrobicular ring clamping being arranged on base so that pipe cap and base are securely attached to together, structure was both simple, and was not practical.

Further, the pipe cap inwall is provided with twice bulge loop, and bulge loop described in twice is arranged at pipe cap bottom, the pipe The twice scrobicular ring being adapted with twice bulge loop is provided with seat.

By adopting above-mentioned technical proposal, by a plurality of bulge loop and scrobicular ring so that pipe cap and base clamping are more It is firm.

Further, the bulge loop is arranged into semi arch, and the bulge loop is arranged in semi arch, and the scrobicular ring is in and bulge loop phase The semi arch of adaptation is arranged.

By adopting above-mentioned technical proposal, the contact area of semi arch is big, enables to pipe cap and base can be more steady Fixed is connected together, and will not produce and rock, so as to not affect normally using for laser diode.

In sum, this utility model has the advantages that：By arranging twice semi arch bulge loop on pipe cap, The semi arch scrobicular ring matched with twice semi arch bulge loop is set, using simple frame for movement so that pipe cap and pipe on base Both can firmly connect between seat, and not lose the mobility that can arbitrarily dismount as needed.

Specific embodiment

This utility model is described in further detail below in conjunction with accompanying drawing.

As shown in figures 1 and 3, a kind of laser diode, including pipe cap 1 and base 2, the pipe cap 1 is coaxially disposed useful In the lens 3 of focused laser beam, laser chip 4 is integrated with the base 2, the described inwall of pipe cap 1 is provided with convex 6 are played, positioning convex 6 is made up of silastic material, and base 2 is engaged by clamping with pipe cap 1, is provided with for clamping in the inwall of base 2 The locating slot 5 of positioning convex 6.By way of positioning convex 6 and the clamping of locating slot 5, to realize the connection of pipe cap 1 and base 2, Both easy connected mode of the pipe cap 1 with base 2, causes pipe cap 1 more to have mobility with the connection of base 2 again, can be with root Arbitrarily collocation pipe cap 1 and base 2, convenient dismounting are needed according to concrete；But will not be that the connection of pipe cap 1 and base 2 becomes gender gap, Affect normally using for laser diode.

As shown in Figures 2 and 3, above-mentioned positioning convex 6 is arranged in the inwall of pipe cap 1 in bulge loop, with the phase of the positioning convex 6 Corresponding base 2 be provided with for the inwall bulge loop of clamping pipe cap 1 locating slot 5 be scrobicular ring.Bulge loop is arranged on pipe cap 1 can be increased Plus the structural strength of pipe cap 1, can reach again and the scrobicular ring clamping function on base 2, the above-mentioned inwall of pipe cap 1 is specifically provided with Twice bulge loop, twice bulge loop is all disposed within position of the pipe cap 1 near bottom, is provided with base 2 and is adapted with twice bulge loop Twice scrobicular ring.Bulge loop and scrobicular ring arrange a plurality of, primarily serve the more firm effect for causing pipe cap 1 and the clamping of base 2. At the same time, positioning convex 6 annular in shape is made by silastic material, additionally it is possible to play a part of to seal pipe cap 1 and base 2, Avoid dust from entering between pipe cap 1 and base 2 and affect the normal operation of laser chip 4, be finally reached prolongation laser diode The purpose of service life, bulge loop is arranged in semi arch, and scrobicular ring is arranged in the semi arch being adapted with bulge loop.The contact surface of semi arch Product is big, and enable to that pipe cap 1 and base 2 can be more stable is connected together, and will not produce and rock.

This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model Field technique personnel can make as needed the modification without creative contribution after this specification is read to the present embodiment, but As long as all being protected by Patent Law in right of the present utility model.
