Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser calibration, and in particular to a sleeve-type laser calibrator. Background Technology
[0002] As is well known, firearms such as pistols and rifles are equipped with scopes. When using them, the scope needs to be mechanically adjusted according to the actual ballistic trajectory of the firearm to ensure its accuracy. A calibrator is used when adjusting the scope. Currently, commercially available sleeve calibrators have their axis located inside the sleeve, with the axis's shape fitting snugly against the inner wall of the sleeve. The laser calibrator is housed within the axis. The disadvantages of this sleeve-type laser calibrator are: 1. The machining precision requirements for the sleeve's inner cavity and the axis's outer shape are very high, resulting in complex and costly manufacturing; 2. The numerous mating surfaces between the sleeve's inner cavity and the axis's outer shape make it impossible to guarantee coaxiality. Utility Model Content
[0003] The main objective of this application is to provide a sleeve-type laser calibrator that is simple to manufacture, has a low cost, and can ensure the coaxiality of the sleeve and the laser source.
[0004] To achieve the above objectives, this utility model provides a sleeve-type laser calibrator, comprising:
[0005] A sleeve, wherein an axially through-hole is formed inside the sleeve;
[0006] An axial laser source, wherein the axial laser source has a cylindrical structure and is releasably installed within the axial through channel via a tapered fit.
[0007] Furthermore, the axial through channel has a front opening and a rear opening arranged opposite to each other at both ends.

[0008] Furthermore, the axial laser source has a head, a main body, and a tail. A gradient outer conical surface is formed on the outer surface of the main body. The cross-section of the gradient outer conical surface is circular, and its diameter decreases continuously from the tail towards the head.
[0009] Furthermore, the dimensions of the axial laser source are configured such that when the axial laser source is inserted into the sleeve from the rear opening of the sleeve by the head, the gradient outer conical surface of the axial laser source contacts and locks with the gradient inner conical surface of the sleeve, and the axial laser source coincides with the central axis of the sleeve.
[0010] Furthermore, the inner wall taper and cross-sectional circle diameter of the sleeve remain constant within a set range to accommodate the axial laser light source, and the length of the sleeve and the wall thickness of the outer wall of the sleeve have different dimensions to accommodate different gun barrel models.
[0011] Furthermore, the head is provided with an emission through hole for emitting a laser beam, and the emission direction of the laser beam is consistent with the central axis of the sleeve.
[0012] Furthermore, it also includes an end cap that is detachably and fixedly connected to the rear opening.
[0013] Furthermore, the inner wall of the rear opening is provided with an internal thread, and the end cap is provided with an external thread that engages with the internal thread.
[0014] Furthermore, the end cap has an inner cavity that communicates with the inside of the sleeve to accommodate the length portion of the axial laser light source extending from the rear opening.
[0015] Furthermore, the sleeve is made of metal.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0030] Figure 1 An embodiment of a sleeve-type laser calibrator disclosed in this utility model is shown, the sleeve-type laser calibrator comprising:
[0031] Sleeve 1, wherein an axially through channel 13 is formed inside sleeve 1;
[0032] A axial laser source 2, which has a cylindrical structure, is releasably installed within the axial through-channel 13 via a tapered fit. Due to the tapered fit, the sleeve 1 and the axial laser source 2 can be coaxially aligned during simple installation.
[0033] In some embodiments, the axial through channel 13 has a front opening 11 and a rear opening 12 disposed opposite to each other at both ends. A gradually tapered inner conical surface is formed on the inner wall of the axial through channel 13, extending from the rear opening 12 to the front opening 11. The cross-section of the gradually tapered inner conical surface is circular, and its diameter decreases continuously along the direction from the rear opening to the front opening. Figure 5 It shows Figure 4 The schematic diagram of the cross-section of the sleeve BB shown in the figure shows that the cross-sectional diameter d1 of the gradient inner conical surface of the rear opening 12 is larger than the cross-sectional diameter d2 of the gradient inner conical surface of the front opening 11. Compared with processing the inner wall into an inner cylindrical surface of the same diameter with high flatness requirements, the process precision required for processing into a gradient inner conical surface is lower, thus reducing processing costs.
[0034] In some embodiments, the axial laser source 2 has a head 21, a main body 22 and a tail 23. A gradient outer conical surface is formed on the outer surface of the main body 22. The cross-section of the gradient outer conical surface is circular, and its diameter decreases continuously from the tail 23 toward the head 21. Figure 2 A side view of the axial laser source is shown. As can be seen from the figure, the cross-sectional diameter d3 of the gradient outer conical surface near the tail 23 is larger than the diameter d4 of the gradient outer conical surface near the head. Compared with machining the outer surface into an outer cylindrical surface of the same diameter with high flatness requirements, machining the gradient outer conical surface requires lower process precision and can also achieve good coaxiality with the gradient inner conical surface, thus reducing processing costs.
[0035] refer to Figures 6 to 7 , Figure 6 This is a schematic diagram showing the fit between the sleeve and the central laser source. Figure 7 for Figure 6 The diagram shows a CC cross-section of the sleeve and the central laser source. In some embodiments, the dimensions of the central laser source 2 are configured such that when the central laser source 2 is inserted into the sleeve 1 through the rear opening 12 of the sleeve 1 by the head 21, the tapered outer surface of the central laser source 2 contacts and locks with the tapered inner surface of the sleeve 1, and the central axis of the central laser source 2 coincides with that of the sleeve 1. This tapered fit facilitates assembly and disassembly and achieves excellent coaxiality.
[0036] In some embodiments, the inner wall taper and cross-sectional diameter of the sleeve 1 remain constant within a set range to accommodate the axial laser light source 2. The length and outer wall thickness of the sleeve 1 have different dimensions to accommodate different gun barrel models. In use, the dimensions of the axial laser light source 2 can remain constant; only the appropriate sleeve 1 needs to be fitted according to the different gun barrel models. Furthermore, the sleeve 1 is simple to manufacture, thus further saving on manufacturing costs.
[0037] In some embodiments, the head 21 is provided with a emission through-hole 211 for emitting a laser beam, and the emission direction of the laser beam is consistent with the central axis of the sleeve 1. When adjusting the sight using this sleeve-type laser calibrator, the coaxiality is high and the pointing is precise, thus the adjustment accuracy is more accurate and reliable.
[0038] In some embodiments, an end cap 3 is further included that is detachably and fixedly connected to the rear opening. The end cap 3 can prevent the axial laser light source 2 from slipping out of the sleeve 1 during use, thus avoiding the risk of damage to the axial laser light source 2 due to falling.
[0039] In some embodiments, the inner wall of the rear opening is provided with an internal thread, and the end cap is provided with an external thread that engages with the internal thread. The thread processing technology is mature, the connection is stable and reliable, and it is suitable for industrial mass production.
[0040] In some embodiments, the end cap 3 has an inner cavity communicating with the interior of the sleeve 1 to accommodate the length portion of the axial laser source 2 extending from the rear opening 12. Since the sleeve 1, which adapts to a portion of the barrel size, is relatively short, to avoid the head 21 extending too far out of the sleeve 1 and interfering with the barrel, the sleeve 1 can be designed to mount the axial laser source 2 at a position relatively centered within the sleeve 1, allowing the length portion of the axial laser source extending from the rear opening to be accommodated within the cavity of the end cap 3.
[0041] In some embodiments, the sleeve is made of metal; further, a copper-zinc alloy can be used, which has the characteristics of good toughness, corrosion resistance, and easy processing.
[0042] The laser calibrator according to this application is simple to manufacture, has low cost, and can ensure the coaxiality of the sleeve and the laser source on the axis.
