Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
The camera lens module of one embodiment of the present of invention, as depicted in figs. 1 and 2, including：
The both ends of body tube 100, body tube 100 are directed towards the object end of shooting object and the picture end towards user；
Microscope group 210 and second is fixed in body tube 100 from object end to the image end direction time interval fixed first to fix
Microscope group 220 and first fixes between microscope group 210 and second fixes microscope group 220 and forms airtight chamber；
It is arranged first between fixing the fixation microscope group 220 of microscope group 210 and second first and with the first ventilation device to transport
Index glass group 310, the space of the first 310 both sides of movement microscope group is connected the first ventilation device and first moves microscope group 310 outside
It is moved between the first fixation microscope group 210 and second fixes microscope group 220 under force effect.
The camera lens module of the present embodiment, including body tube, time interval be fixed in body tube first fix microscope group and
Second fixes microscope group, in this way, forming airtight chamber between the first fixation microscope group and the second fixation microscope group in body tube；With
First movement microscope group setting of one ventilation device is between first fixes microscope group and second fixes microscope group, and the first ventilation device is by the
The space of one movement microscope group both sides is connected.Since the space of the first movement microscope group both sides is connected by the first ventilation device,
Under the action of external force, when the first movement microscope group moves between the first fixation microscope group and the second fixation microscope group, gas passes through first
For ventilation device in the spatial flow of the first movement microscope group both sides, i.e., the pressure of the gas of the first movement microscope group both sides is suitable, and first
Movement microscope group can be moved smoothly, while ensure that camera lens microscope group relative to extraneous seal, improves the bat of camera lens module
The effect taken the photograph.It is simple in structure meanwhile as long as the first ventilation device is arranged in the first movement microscope group, convenient for manufacture.
Specific to the realization method of the first ventilation device, can there are many.Such as can be at least one from object end to the image end
Venthole and/or air channel of the direction through the first movement microscope group；When the first movement microscope group includes at least one eyeglass and fixation
The preceding lens barrel of eyeglass, can also be it is as shown in Figure 3 and Figure 4 it is at least one from object end to the image end direction before preceding lens barrel
Lens barrel venthole 311 and/or preceding lens barrel air channel.
It should be noted that as long as the specific implementation of above-mentioned first ventilation device is only used for for example, can incite somebody to action
The structure that the space of first movement microscope group both sides is connected can.
Further, as shown in Figure 1 and Figure 5, camera lens module can also include shell 400, in body tube from object end to
The third being arranged as extreme direction time interval fixes microscope group 230 and second and moves microscope group 320 and third fixation microscope group 230 and second
First chamber is formed between movement microscope group 320, third is fixed microscope group 230 and fixed with body tube, and the second movement microscope group 320 is close to picture
The side at end is communicated with ambient atmosphere；
Body tube 100 is fixed in shell 400 and is formed with second chamber between body tube 100 and shell 400；First chamber
Room is connected with second chamber by the second ventilation device and the second movement microscope group 320 is under external force in body tube 100
Within a preset range microscope group 230 is fixed closer or far from third.
In this way, when the second movement microscope group fixes microscope group closer or far from third under external force, first chamber and second
Chamber is connected by the second ventilation device, and the volume of first chamber and second chamber can change, meanwhile, gas is logical by second
Depressed structure can flow between first chamber and second chamber divides gas capacity, reduces the resistance of the second movement microscope group movement
Power.
The principle requirement of second ventilation device setting is that first chamber can be connected with second chamber, is specifically arranged
Position can be configured according to the structure of each camera lens module.
As a kind of optional mode of the second ventilation device, as shown in figures 1 to 6, the second ventilation device includes running through
The body tube venthole 110 of primary mirror barrel；
As shown in Figure 1 and Figure 7, camera lens module further includes the rear regulation ring 500 being socketed in outside lens barrel, and rear regulation ring 500 is used
In the movement for adjusting the second movement microscope group；Second ventilation device further includes that setting fixes microscope group in rear regulation ring 500 close to third
One end on the inside of annular resigning exhaust step groove 510 and be arranged step down exhaust step groove through adjust ring wall rear adjusting
Ring venthole 520；
Body tube venthole 110 steps down and is vented step groove 510 and rear regulation ring venthole 520 by first chamber and second
Chamber is connected.
In this way, when the second movement microscope group fixes microscope group closer or far from third under external force, body tube venthole allows
First chamber is connected by position exhaust step groove with rear regulation ring venthole with second chamber, the appearance of first chamber and second chamber
Product can change, meanwhile, gas can be flowed by the second ventilation device between first chamber and second chamber divides gas capacity,
Reduce the resistance of the second movement microscope group movement.
A kind of preferred mode of the installation position of body tube venthole, as shown in Figure 1 and Figure 5, body tube venthole 110
Microscope group is fixed close to as the one end at end is adjacent with third.
In this way, during the close third of the second movement microscope group fixes microscope group, the more difficult quilt of body tube venthole
Second movement microscope group covers, and can keep body tube venthole, steps down and is vented step groove and rear regulation ring venthole by the first chamber
Room is connected with second chamber.
A kind of preferred mode of the installation position of regulation ring venthole afterwards, as shown in Figure 1 and Figure 5, rear regulation ring ventilation
Hole 520 is arranged in exhaust step groove of stepping down close to one end of third fixation microscope group.In this way, body tube venthole and rear regulation ring are logical
The distance between stomata smaller, more easily by the gas communication in first chamber to second chamber.
As the optional mode of another kind of the second ventilation device, the second ventilation device includes the primary mirror through primary mirror barrel
First chamber is connected by cylinder venthole, body tube venthole with second chamber.In this way, body tube venthole by first chamber and
Second chamber is connected, and the volume of first chamber and second chamber can change, meanwhile, gas can be by the second ventilation device
Gas capacity is divided in flowing between one chamber and second chamber, reduces the resistance of the second movement microscope group movement.
A kind of preferred mode of the installation position of body tube venthole, body tube venthole and third fixation microscope group are close
As the one end at end is adjacent.
In this way, during the close third of the second movement microscope group fixes microscope group, the more difficult quilt of body tube venthole
Second movement microscope group covers, and can keep body tube venthole that first chamber is connected with second chamber.
