Description

Technical Field

[0001] The utility model relates to the field of sights, in particular to a sight structure. Background Art

[0002] At present, rifle scopes with prisms are becoming more and more a necessity for shooters. The reason is that rifle scopes with prisms can be made very mini and compact, and they have an absolute advantage in length.

[0003] See also Figure 1 In traditional prism scopes, the sealing ring is installed on the outer wall of the eyepiece barrel, and the sealing ring will move synchronously with the movement of the eyepiece barrel in the scope body. In this case, during the adjustment of the emmetropia and minus diopter, the eyepiece barrel will have two moving ranges: the moving range of the thread on the eyepiece barrel and the moving range of the sealing ring on the outer wall of the eyepiece barrel. A moving area for the sealing ring needs to be reserved on the inner wall of the scope, which will increase the overall length of the scope, which hinders the further miniaturization of the prism scope. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and provide a sighting mirror structure.

[0005] According to one aspect of the utility model, a sighting scope structure is provided, comprising a scope body, an eyepiece barrel and an eyepiece handwheel, wherein a first end of the scope body is provided with a first internal thread, a first end of the eyepiece barrel is screwed into the first internal thread, and the eyepiece handwheel is provided on a second end of the eyepiece barrel, and further comprising:

[0006] A limiting ring, wherein the first end of the lens body is provided with a second internal thread, the inner diameter of the second internal thread is greater than the inner diameter of the first internal thread, the limiting ring is sleeved on the eyepiece barrel, the limiting ring is screwed into the second internal thread, and a circle of accommodating grooves is provided on the inner wall of the limiting ring; and

[0007] The sealing ring is accommodated in the accommodating groove and is located between the inner bottom of the accommodating groove and the outer wall of the eyepiece barrel.

[0008] In the sight structure of the utility model, the first internal thread on the lens body is the thread required for the positive and negative diopter adjustment of the eyepiece barrel, and since the sealing ring is arranged in the accommodating groove on the inner wall of the limiting ring, when the eyepiece barrel moves in the lens body, the position of the sealing ring remains stationary, and the sealing ring does not move with the movement of the eyepiece barrel. In this way, during the positive and negative diopter adjustment of the eyepiece barrel, there is only a moving range of the thread on the eyepiece barrel, and the moving range of the sealing ring is cancelled. In this way, there is no need to reserve a moving area for the sealing ring on the inner wall of the lens body, thereby effectively reducing the moving range of the eyepiece barrel, which is conducive to shortening the overall length of the sight. Moreover, the sealing ring is in close contact with the eyepiece barrel, and the isolation and sealing of the inner cavity of the lens body and the external air can be effectively realized. In the sight structure of the utility model, the eyepiece barrel has only a threaded moving part, which can effectively shorten the overall length of the sight, making the sight more compact and miniaturized, and convenient for shooters to carry and use.

[0009] Furthermore, a circle of steps is provided on the inner wall of the first end of the mirror body, the first internal thread and the second internal thread are respectively located on both sides of the step, the second internal thread is closer to the first end of the mirror body than the first internal thread, and the first end face of the limit ring rests on the step.

[0010] Therefore, during the assembly process, the limit ring with the sealing ring installed in the accommodating groove is first put on the eyepiece barrel. After the eyepiece barrel is rotated into the lens body, the limit ring is rotated into the second internal thread to complete the installation of the limit ring and the sealing ring. It is very convenient. When the limit ring is tightened, it can prevent the eyepiece barrel from falling off the lens body during the screwing process.

[0011] Furthermore, the inner diameter of the limiting ring is smaller than the inner diameter of the first internal thread.

[0012] Therefore, in this case, when the limit ring is tightened, the limit ring can not only limit the emmetropia adjustment of the eyepiece barrel but also prevent the eyepiece barrel from falling off the lens body during the screwing process.

[0013] Furthermore, a clamping groove is provided on the second end surface of the limiting ring.

[0014] Therefore, the limiting ring can be rotated by inserting the clamp into the slot to tighten or disassemble the limiting ring.

[0015] Furthermore, there are two card slots, which are arranged opposite to each other.

[0016] Therefore, the limiting ring can be tightened or loosened very conveniently by inserting the U-shaped clamp into the two slots.

[0017] Furthermore, a first external thread matched with the second internal thread is provided on the outer wall of the limiting ring, and the first external thread is screwed into the second internal thread.

[0018] Therefore, the limiting ring can be stably mounted on the lens body through the cooperation of the first external thread and the second internal thread to limit the emmetropia adjustment of the eyepiece barrel.

[0019] Furthermore, a second external thread is provided on the outer wall of the second end of the eyepiece barrel, a third internal thread matched with the second external thread is provided on the inner wall of the eyepiece handwheel, and the third internal thread is screwed onto the second external thread.

[0020] Therefore, the eyepiece handwheel can be quickly installed on the eyepiece barrel through the threaded connection structure. When the eyepiece handwheel is tightened, the eyepiece handwheel is turned, and the eyepiece handwheel can drive the eyepiece barrel to rotate synchronously, thereby realizing the adjustment of the emmetropia and minus memetropia of the eyepiece barrel.

[0021] Furthermore, the outer diameter of the eyepiece hand wheel is greater than the inner diameter of the limiting ring.

[0022] Therefore, when adjusting the negative diopter of the eyepiece barrel, since the outer diameter of the eyepiece handwheel is larger than the inner diameter of the limit ring, when the end face of the eyepiece handwheel abuts against the limit ring, this position is the maximum value of the negative diopter adjustment of the eyepiece barrel.

[0023] Furthermore, protrusions arranged at intervals are provided on the outer wall of the eyepiece handwheel.

[0024] Therefore, the protrusions arranged at intervals can increase the friction, making it easier for the shooter to turn the eyepiece handwheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 4 and Figure 5 A first internal thread 11 and a second internal thread 12 are formed on the inner wall of the first end of the lens body 1, and the inner diameter of the second internal thread 12 is larger than the inner diameter of the first internal thread 11. A circle of steps 13 is also formed on the inner wall of the first end of the lens body 1, and the first internal thread 11 and the second internal thread 12 are respectively located on both sides of the step 13. The second internal thread 12 is closer to the end of the first end of the lens body 1 than the first internal thread 11.

[0035] See also Figure 5 A third external thread 22 is formed on the outer wall of the first end of the eyepiece barrel 2, and the third external thread 22 is adapted to the first internal thread 11 on the lens body 1. The first end of the eyepiece barrel 2 is screwed into the first internal thread 11 through the third external thread 22, and the axial length range of the first internal thread 11 is the moving range of the third external thread 22 on the eyepiece barrel 2.

[0036] See also Figures 4 to 6A first external thread 43 is formed on the outer wall of the limiting ring 4, and the first external thread 43 is adapted to the second internal thread 12 on the lens body 1. The limiting ring 4 can be screwed into the second internal thread 12 through the first external thread 43. The inner diameter of the limiting ring 4 is slightly larger than the outer diameter of the eyepiece barrel 2. The limiting ring 4 is sleeved on the eyepiece barrel 2. A circle of accommodating grooves 41 are formed on the inner wall of the limiting ring 4. The sealing ring 5 is accommodated in the accommodating groove 41. When installing the limiting ring 4, the sealing ring 5 is first clamped in the accommodating groove 41, and then the limiting ring 4 is sleeved on the eyepiece barrel 2. When the eyepiece barrel 2 is screwed into the lens body 1, the limiting ring 4 is screwed into the second internal thread 12, and the limiting ring 4 is tightened. , the first end face of the limit ring 4 abuts against the step 13, and the installation of the limit ring 4 and the sealing ring 5 is completed at this time, which is very convenient. Since the sealing ring 5 is located between the inner bottom of the accommodating groove 41 and the outer wall of the eyepiece barrel 2, the sealing ring 5 is in close contact with the eyepiece barrel 2, which can effectively realize the isolation and sealing of the inner cavity of the lens body 1 and the outside air. In addition, since the inner diameter of the second internal thread 12 is larger than the inner diameter of the first internal thread 11, the second internal thread 12 can provide an installation space for the limit ring 4. The limit ring 4 can be firmly installed on the lens body 1 through the cooperation of the first external thread 43 and the second internal thread 12 to limit the emmetropia adjustment of the eyepiece barrel 2.

[0037] The inner diameter of the limiting ring 4 is smaller than the inner diameter of the first internal thread 11 , so that when the limiting ring 4 is tightened, the limiting ring 4 can both limit the emmetropia adjustment of the eyepiece barrel 2 and prevent the eyepiece barrel 2 from coming off the lens body 1 during the screwing process.

[0038] See also Figure 2 , Figure 5 and Figure 6 A slot 42 is formed on the second end surface of the limit ring 4. There are two slots 42, which are arranged opposite to each other. In this way, the limit ring 4 can be tightened or loosened very conveniently by inserting a U-shaped clamp into the two slots 42.

[0039] See also Figure 2 and Figure 4 The eyepiece hand wheel 3 is mounted on the second end of the eyepiece barrel 2. Figure 5 A second external thread 21 is formed on the outer wall of the second end of the eyepiece barrel 2, and a third internal thread 31 is formed on the inner wall of the eyepiece handwheel 3. The third internal thread 31 is adapted to the second external thread 21. The eyepiece handwheel 3 is screwed on the second external thread 21 through the third internal thread 31. The eyepiece handwheel 3 can be quickly installed on the eyepiece barrel 2 through the threaded connection structure. When the eyepiece handwheel 3 is tightened, the eyepiece handwheel 3 is rotated, and the eyepiece handwheel 3 can drive the eyepiece barrel 2 to rotate synchronously, thereby realizing the adjustment of the emmetropia and minus diopter of the eyepiece barrel 2.

[0040] See also Figure 4, the outer diameter of the eyepiece hand wheel 3 is larger than the inner diameter of the limit ring 4. In this case, when adjusting the negative diopter of the eyepiece tube 2 ( Figure 4 The eyepiece barrel 2 moves to the left). Since the outer diameter of the eyepiece hand wheel 3 is larger than the inner diameter of the limit ring 4, when the end face of the eyepiece hand wheel 3 ( Figure 4 When the left end face of the middle eyepiece hand wheel 3 abuts against the limit ring 4, this position is the maximum value of the negative diopter adjustment of the eyepiece barrel 2.

[0041] See also Figure 2 and Figure 5 The outer wall of the eyepiece hand wheel 3 is formed with protrusions 32 arranged at intervals, and the protrusions 32 arranged at intervals can increase the friction force, making it convenient for the shooter to rotate the eyepiece hand wheel 3.

[0042] See also Figures 2 to 5 The eyepiece barrel 2 is provided with a sealing ring 5 which is arranged in the receiving groove 41 on the inner wall of the limiting ring 4. When the eyepiece barrel 2 moves in the eyepiece barrel 2, the sealing ring 5 remains in a fixed position, and the sealing ring 5 does not move with the movement of the eyepiece barrel 2. In this way, during the positive and negative diopter adjustment of the eyepiece barrel 2, only the moving range of the third external thread 22 on the eyepiece barrel 2 exists, and the moving range of the sealing ring 5 is cancelled. In this way, there is no need to reserve a moving area of ​​the sealing ring 5 on the inner wall of the eyepiece barrel 1, thereby effectively reducing the moving range of the eyepiece barrel 2, which is conducive to shortening the overall length of the sight. In addition, the sealing ring 5 is in close contact with the eyepiece barrel 2, which can effectively realize the isolation and sealing of the inner cavity of the eyepiece barrel 1 and the outside air. In the sight structure of the utility model, the eyepiece barrel 2 has only a threaded moving part, which can effectively shorten the overall length of the sight, make the sight more compact and miniaturized, and be convenient for shooters to carry and use.
