Description

Technical Field

[0001] This utility model relates to the field of aiming technology, specifically a magnetic bullet cover for a firearm aiming scope. Background Technology

[0002] Existing firearm scopes have scope caps installed at both ends to protect the scope lens. The existing scope caps are directly fixed to the end of the scope via a sleeve fixing structure, which is inconvenient to remove and install. In addition, an elastic torsion spring is installed between the scope cap and the sleeve to allow the scope cap to open quickly. To match the function of the torsion spring, a retaining device is also set between the scope cap and the sleeve so that the scope cap is fixed on the sleeve when not open. The existing retaining device structure uses a snap-fit ​​method, with a retaining ring made of deformable material on the base surface of the scope cap and the sleeve to achieve the snap-fit ​​between the scope cap and the sleeve. This method requires a certain amount of pushing force to open the scope cap, and the retaining ring is prone to wear, which leads to the failure of the retaining device and a short service life.

[0003] The existing lens cover and sleeve are under the elastic action of a torsion spring after being opened. The lens cover has a certain degree of mobility. During violent movement, the lens cover will collide with other objects, causing wear or deviation, making it impossible for the lens cover to maintain a sealed connection with the sleeve.

[0004] Therefore, we propose a magnetic bullet cover for firearm sights to solve the problems mentioned above. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a magnetic cartridge cover for a firearm sight, comprising: a cartridge cover body 1 and a lens sleeve 2, the cartridge cover body 1 and the lens sleeve 2 are hinged together, and the lens sleeve 2 is fixedly snapped onto the end of the sight. The sight is protected by the cooperation of the cartridge cover body 1 and the lens sleeve 2.

[0033] The hinge of the spring cover body 1 and the lens sleeve 2 is provided with an elastic hinge structure 4, which is used to quickly spring open the spring cover body 1 relative to the lens sleeve 2, thereby increasing the opening speed of the spring cover body 1.

[0034] The elastic hinge structure 4 includes a hinge sleeve 41 and a hinge ear 42. The hinge sleeve 41 is integrally formed with the spring cover body 1, and the hinge ear 42 is integrally formed on the lens sleeve 2. The hinge sleeve 41 and the hinge ear 42 are connected in series by a second connecting rod 45. The hinge sleeve 41 and the hinge ear 42 are rotatably connected to the second connecting rod 45, so that the spring cover body 1 and the lens sleeve 2 can rotate relative to each other about the second connecting rod 45 as an axis.

[0035] A limiting cavity 43 is provided inside the hinge sleeve 41, and a torsion spring 44 is provided inside the limiting cavity 43. The torsion spring 44 is sleeved on the second connecting rod 45. One end of the torsion spring 44 is fixedly inserted into the limiting cavity 43, and the other end of the torsion spring 44 is fixedly inserted into the hinge ear 42. When the spring cover body 1 and the lens sleeve 2 are not under force, the torsion spring 44 returns to the normal state, and the spring cover body 1 is lifted up, so that it opens 270° relative to the lens sleeve 2. When the spring cover body 1 rotates and presses on the lens sleeve 2, the torsion spring 44 is compressed.

[0036] A magnetic stabilizing structure 5 is provided between the spring cover body 1 and the lens sleeve 2. The magnetic stabilizing structure 5 is used to fix the spring cover body 1 relative to the lens sleeve 2 after it is opened, so that the spring cover body 1 remains in a stable state after it is opened, reducing the probability of the spring cover body 1 colliding with other objects.

[0037] The magnetic stabilizing structure 5 includes a magnetic ring 54 and a second magnetic piece 52. The magnetic ring 54 is installed on the spring cover body 1, and the second magnetic piece 52 is installed on the upper end of the lens sleeve 2. When the spring cover body 1 is rotated 270° relative to the lens sleeve 2, the second magnetic piece 52 and the magnetic ring 54 are magnetically connected, and the spring cover body 1 is magnetically fixed to the lens sleeve 2.

[0038] Specifically, the magnetic ring 54 is fixedly installed on the positioning clip 53. The positioning clip 53 is inserted and connected to the limiting ring 51 on the spring cover body 1. The limiting ring 51 is integrally set on the inner wall of the spring cover body 1. The spring cover body 1 has a through hole through which the positioning clip 53 passes at the limiting ring 51, so that the magnetic ring 54 can be fixed and can fit the second magnetic suction piece 52.

[0039] A magnetic spring cover structure 3 is provided between the spring cover body 1 and the lens sleeve 2. The magnetic spring cover structure 3 is used to magnetically fix the unopened spring cover body 1 to the lens sleeve 2. The magnetic force is greater than the torsion of the torsion spring 44, so that the spring cover body 1 can be stably fixed to cover the lens sleeve 2. When it is necessary to open the spring cover body 1, the magnetic spring cover structure 3 can be used to more easily and conveniently detach the spring cover body 1 and the lens sleeve 2.

[0040] Specifically, the magnetic snap cover structure 3 includes a first magnetic snap piece 31, which is fixedly embedded in the protrusion 11. The protrusion 11 is integrally connected to the snap cover body 1 and is located on the side of the snap cover body 1.

[0041] The magnetic snap-on cover structure 3 also includes a third magnetic snap-on piece 33, which is fixedly embedded in the round hole 322 of the support base 32. The support base 32 is fixedly installed on the side of the lens sleeve 2 and its position corresponds to the protrusion 11. The first magnetic snap-on piece 31 and the third magnetic snap-on piece 33 are magnetically connected to achieve magnetic fixation of the snap-on cover body 1 and the lens sleeve 2.

[0042] A pry bar 36 is rotatably mounted inside the support base 32 via a first connecting rod 34. A set of like-pole repulsive magnetic blocks is provided between the pry bar 36 and the support base 32. The set of like-pole repulsive magnetic blocks includes a first magnetic block 37 and a second magnetic block 363. The first magnetic block 37 is embedded in the circular groove 323 opened in the support base 32, and the first magnetic block 37 is embedded in the pry bar 36. By utilizing the principle of like poles repulsion of magnets, the lower end of the pry bar 36 is raised, and the upper end of the pry bar 36 is embedded in the support base 32.

[0043] The pry bar 36 includes a pressure bar 361 and a push bar 362. The support base 32 has a groove 321 for accommodating the push bar 362. In the normal state, the pressure bar 361 is raised and the push bar 362 is embedded in the groove 321. The protrusion 11 and the support base 32 can be smoothly attached, so that the first magnetic absorbing piece 31 and the third magnetic absorbing piece 33 are attached and magnetically connected. By using the lever principle to press the pressure bar 361, the push bar 362 is raised, pushing the protrusion 11 away, so that the first magnetic absorbing piece 31 and the third magnetic absorbing piece 33 are separated. The spring cover body 1 immediately springs up and opens using the elastic hinge structure 4.

[0044] The lens sleeve 2 has several elastic clips 21 on its side. The elastic clips 21 use their own material deformation to clip onto the lens of the scope, so that the lens sleeve 2 can be quickly installed on the scope.

[0045] Anti-warping structures are provided on the right sides of the spring cover body 1 and the lens sleeve 2. The anti-warping structure includes a magnetic post 121 and a magnetic post 23. The magnetic post 121 is embedded and fixedly installed in the insertion hole 12 of the spring cover body 1, and the magnetic post 23 is embedded and fixedly installed in the thickened protruding edge 22 integrally provided on the lens sleeve 2. When the spring cover body 1 is placed on the lens sleeve 2, the magnetic post 121 and the magnetic post 23 are magnetically attracted, so that the spring cover body 1 is fixed on the lens sleeve 2, preventing the spring cover body 1 from shifting and warping relative to the lens sleeve 2.

[0046] Working principle: When the scope needs to be opened, press the pressure rod 361 of the magnetic cartridge cover structure 3 to lift the top rod 362 and push the protrusion 11 away from the support base 32. The magnetic attraction force of the third magnetic piece 33 and the first magnetic piece 31 is weakened. At this time, the torsion spring 44 returns to its original position and opens the cartridge cover body 1. It rotates 270° relative to the lens sleeve 2. The second magnetic piece 52 and the magnetic ring 54 of the magnetic stabilizing structure 5 magnetically attract each other and fix the cartridge cover body 1 on the lens sleeve 2. At this time, the scope can be used smoothly.

[0047] When the scope is no longer in use, press the cartridge cover body 1 by hand to cover the lens sleeve 2. The magnetic cartridge cover structure 3 magnetically fixes the cartridge cover body 1 and the lens sleeve 2 to protect the lens of the scope.

[0048] When the cartridge cover body 1 is closed, the anti-warping structure makes the cartridge cover body 1 more stable and prevents it from shifting or warping.

[0049] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
