Description

Technical Field

[0001] This invention relates to the field of scope manufacturing technology, and more particularly to a scope testing device. Background Technology

[0002] Once a scope is mounted on a firearm, it will be subjected to the powerful recoil from firing and the forward thrust of the recoil spring during use. If the scope's impact resistance is substandard, it may break during use, which will greatly affect its performance. Therefore, a scope impact testing device is needed to test the scope's impact resistance.

[0003] To address the above issues, patent document CN221594648U discloses a scope impact testing device, including a support frame, a drive unit, and a scope clamp. The scope clamp is mounted on the support frame. The device also includes a rebound mechanism. The drive unit, scope clamp, and rebound mechanism are arranged along the movement direction of the drive unit. The drive unit is positioned above the scope clamp, and the rebound mechanism is positioned below the scope clamp. The drive unit drives the scope clamp to move along the movement direction. The rebound mechanism includes a spring guide post and a spring. The spring guide post is fixed to the support frame, and the spring is sleeved on the spring guide post. The scope clamp includes a baffle that passes through the spring guide post and abuts against the spring. By testing the scope for impact and the forward reset of the recoil spring, the scope testing becomes more accurate.

[0004] However, existing scope impact testing devices cannot limit the position of the scope clamp during actual use. This causes the output of the drive mechanism to fail to reset in time when the spring's restoring force simulates the forward reset of a firearm's recoil spring, thus interfering with the reset of the scope clamp and affecting the test results. Summary of the Invention

[0005] The purpose of this invention is to provide a scope testing device, which aims to solve the technical problem that existing scope impact testing devices cannot limit the position of the scope clamp during actual use. As a result, when the spring's restoring force simulates the forward reset of a firearm's recoil spring and impacts the scope, the output end of the drive mechanism cannot reset in time, which interferes with the reset of the scope clamp and affects the test results.

[0006] To achieve the above objectives, the present invention provides a scope testing device, including a support frame, a drive mechanism, a return mechanism, a scope clamp, and a limiting mechanism. The drive mechanism, the scope clamp, and the return mechanism are arranged sequentially from top to bottom on the support frame. The output end of the drive mechanism is located above the scope clamp, and the compression end of the return mechanism is in contact with the bottom of the scope clamp. The limiting mechanism includes a fixed plate, a drive assembly, a limiting shaft, a threaded rod, a support arm, and a limiting member. The support arm is slidably disposed in the middle of the support frame, and the limiting member is disposed at the top of the support arm. The limiting member corresponds to the top of the scope clamp. The fixed plate is also fixedly disposed in the middle of the support frame. The limiting shaft is rotatably disposed on the fixed plate. The threaded rod is internally threaded to the limiting shaft. The end of the threaded rod is connected to the support arm through a connecting bearing. The drive assembly is also disposed on the fixed plate. A transmission gear is disposed outside the limiting shaft. The output end of the drive assembly is mechanically driven by the transmission gear.

[0007] The drive assembly includes a drive motor, a gear reducer, and an output gear. The drive motor is mounted on the fixed plate, the gear reducer is located at the output end of the drive motor, and the output gear is located at the output end of the gear reducer. The output gear meshes with the transmission gear.

[0008] The support arm includes a fixed section and an adjustable section. A mounting plate is provided in the middle of the support frame. The fixed section is slidably mounted on the mounting plate. The connecting bearing is mounted on the side wall of the fixed section. The adjustable section is slidably provided at the end of the fixed section away from the mounting plate. The limiting member is provided at the top of the adjustable section. An adjusting component is provided inside the fixed section. The output end of the adjusting component is connected to the inner bottom wall of the adjustable section.

[0009] The adjustment assembly includes a servo motor, a lead screw, and a lead screw sleeve. The servo motor is installed at the inner bottom of the fixed section. The lead screw is provided at the output end of the servo motor. The lead screw sleeve is provided on the lead screw. The lead screw sleeve is detachably connected to the inner bottom wall of the adjustment section.

[0010] The limiting shaft has two limiting rings on its outside, and the two limiting rings are located on opposite sides of the fixing plate.

[0011] Each of the limiting rings has an annular groove on the side near the fixing plate, and multiple balls are arranged inside the annular groove, with the balls fitting against the surface of the fixing plate.

[0012] The aiming scope testing device also includes a protective shell, which is also provided on the fixing plate. The protective shell is located outside the output gear and the transmission gear.

[0013] An injection tube is provided through the protective shell, and a sealing plug is provided at the end of the injection tube away from the protective shell.

[0014] The aiming scope testing device also includes a heat sink, which is provided on the side wall of the fixed section. The heat sink has heat dissipation grooves, which correspond to the servo motor.

[0015] The heat sink has a slot at one end extending to the outside of the fixed section, the slot passes through the heat sink groove, and a filter screen is provided at the slot.

[0016] A scope testing device of the present invention, when testing the forward reset of the scope's recoil spring, when the drive mechanism is activated, causing the scope clamp to descend and the spring of the return mechanism to be in a compressed state, the drive assembly is activated, and the transmission gear drives the limiting shaft to rotate on the fixed plate. Since the limiting shaft does not displace when rotating on the fixed plate, and the threaded rod is internally threaded to the limiting shaft, the threaded rod displaces while rotating inside the limiting shaft, thereby driving the support through the connecting bearing. The arm slides in the middle of the support frame, thereby limiting the end of the scope holder. After the output end of the drive mechanism is reset, the support arm is driven to reset through the cooperation of the drive assembly, the limiting shaft and the threaded rod. This allows the scope holder to reset under the restoring force of the rebound mechanism, completing the test of the impact of the thrust of the recoil spring on the scope. By using the above mechanism, the problem of the drive mechanism not resetting in time and interfering with the reset of the scope holder can be avoided, making the test results of the scope more accurate.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] First embodiment: Please see Figures 1 to 6 ,in Figure 1 This is a schematic diagram of the structure of the aiming scope testing device according to the first embodiment. Figure 2 This is a formal drawing of the scope testing device of the first embodiment. Figure 3 This is a schematic diagram of the limiting mechanism in the first embodiment. Figure 4 yes Figure 1 A magnified view of the local structure at point A. Figure 5 This is a schematic diagram of the disassembled structure of the support arm in the first embodiment. Figure 6 This is a schematic diagram of the limiting rotating shaft in the first embodiment.

[0029] This invention provides a scope testing device, comprising a support frame 101, a drive mechanism 102, a return mechanism 103, a scope clamp 104, and a limiting mechanism. The limiting mechanism includes a fixed plate 105, a drive assembly, a limiting shaft 106, a threaded rod 107, a support arm, and a limiting member 108. The drive assembly includes a drive motor 109, a gear reducer 110, and an output gear 111. The support arm includes a fixed section 112 and an adjusting section 113. This solution addresses the problem in existing scope impact testing devices where the position of the scope clamp 104 cannot be limited during actual use. This results in the output end of the drive mechanism 102 failing to reset promptly when the scope is impacted by the spring's restoring force mimicking the forward reset force of a firearm's recoil spring. This interferes with the reset of the scope clamp 104, affecting the test results. It is understood that the aforementioned solution can be applied to the structure of a scope impact testing device.

[0030] In this specific embodiment, the support frame 101 is sequentially arranged from top to bottom with the drive mechanism 102, the scope holder 104, and the return mechanism 103. The output end of the drive mechanism 102 is located above the scope holder 104, and the compression end of the return mechanism 103 is in contact with the bottom of the scope holder 104. The scope to be tested is mounted on the scope holder 104. During testing, the output end of the drive mechanism 102 impacts the scope holder 104. The drive mechanism 102 can simulate the impact force of a firearm. At this time, the drive mechanism 102 impacts the scope holder 104 instead of the scope itself, thereby reducing damage to the scope. The scope holder 104 is equipped with a rebound mechanism 103 below it, which mimics the forward return force of a firearm's recoil spring. During testing, the drive mechanism 102 impacts the scope holder 104, causing the scope holder 104 to move downwards. The spring in the rebound mechanism 103 is compressed under pressure. After the spring is compressed, it releases the elastic pressure, and the scope holder 104 moves upwards. This elastic pressure mimics the forward return force of a firearm's recoil spring. By testing the scope with impact and the forward return force of the recoil spring, the scope testing is made more accurate. The drive mechanism 102, the scope holder 104, and the rebound mechanism 103 are all existing technologies, and therefore are not described in detail in this technical solution.

[0031] The support frame 101 has a support arm slidably mounted on its middle section. A limiting member 108 is mounted at the top of the support arm, corresponding to the top of the scope clamp 104. A fixing plate 105 is also fixedly mounted on the middle section of the support frame 101. A limiting shaft 106 is rotatably mounted on the fixing plate 105. A threaded rod 107 is internally threaded onto the limiting shaft 106, and the end of the threaded rod 107 is connected to the support arm via a connecting bearing 114. The fixed plate 105 is also equipped with the drive assembly, and the limiting shaft 106 is externally equipped with a transmission gear 115. The output end of the drive assembly is mechanically transmitted to the transmission gear 115. When testing the forward reset of the sight spring, when the drive mechanism 102 is activated, the sight clamp 104 is lowered, causing the spring of the rebound mechanism 103 to be in a compressed state. At this time, the drive assembly is activated, and the transmission gear 115 drives the limiting shaft 106 on the fixed plate. When the fixed plate 105 rotates, the limiting shaft 106 does not shift when rotating on the fixed plate 105. Furthermore, the threaded rod 107 is internally threaded onto the limiting shaft 106, causing the threaded rod 107 to shift while rotating inside the limiting shaft 106. This shifts the support arm through the connecting bearing 114 to slide in the middle of the support frame 101. Consequently, the limiting member 108 limits the end of the scope clamp 104. After the output end of the drive mechanism 102 resets, the drive assembly, the limiting shaft 106, and the threaded rod 107 work together to reset the support arm. This causes the scope clamp 104 to reset under the restoring force of the rebound mechanism 103, completing the test of the impact of the forward-resetting thrust of a gun recoil spring on the scope. Using this mechanism avoids the problem of the drive mechanism 102 not resetting in time, which could interfere with the reset of the scope clamp 104, resulting in more accurate test results for the scope.

[0032] Secondly, the drive motor 109 is mounted on the fixed plate 105. The output end of the drive motor 109 is provided with the gear reducer 110, and the output end of the gear reducer 110 is provided with the output gear 111. The output gear 111 meshes with the transmission gear 115. When the drive motor 109 is started, the output speed is reduced by the gear reducer 110, which drives the output gear 111 to rotate. Since the output gear 111 meshes with the transmission gear 115, it drives the limiting shaft 106 to rotate on the fixed plate 105.

[0033] Meanwhile, a mounting plate 116 is provided in the middle of the support frame 101. The fixed section 112 is slidably mounted on the mounting plate 116. The connecting bearing 114 is mounted on the side wall of the fixed section 112. An adjusting section 113 is slidably provided at the end of the fixed section 112 away from the mounting plate 116. The limiting member 108 is provided at the top of the adjusting section 113. An adjusting assembly is provided inside the fixed section 112. The adjusting assembly includes a servo motor 117, a lead screw 118, and a lead screw sleeve 119. The servo motor 117 is installed at the inner bottom of the fixed section 112. The output end of the servo motor 117 is provided with... The system includes a lead screw 118 with a lead screw sleeve 119 attached. The lead screw sleeve 119 is detachably connected to the inner bottom wall of the adjusting section 113. When the servo motor 117 is started, the lead screw 118 is rotated. Since the lead screw sleeve 119 is connected to the inner bottom wall of the adjusting section 113, the adjusting section 113 slides inside the fixed section 112, thereby adjusting the height of the support arm. This allows the limiting member 108 to limit the scope clamp 104 at different heights, facilitating the testing of simulating the forward return force of the scope under different sizes of recoil spring thrust, thus enhancing its practicality.

[0034] In addition, two limiting rings 120 are provided on the outside of the limiting shaft 106. The two limiting rings 120 are respectively located on both sides of the fixing plate 105. The setting of the limiting rings 120 makes the structure more stable when the limiting shaft 106 rotates on the fixing plate 105. Each limiting ring 120 has an annular groove 121 on the side close to the fixing plate 105. Multiple balls 122 are arranged inside the annular groove 121. The balls 122 are in contact with the surface of the fixing plate 105. The setting of the annular groove 121 and the balls 122 makes the rotation of the limiting shaft 106 on the fixing plate 105 smoother.

[0035] When using the scope testing device of this embodiment, the scope to be tested is mounted on the scope holder 104. During testing, the output end of the drive mechanism 102 impacts the scope holder 104. The drive mechanism 102 can simulate the impact force of a firearm. At this time, the drive mechanism 102 impacts the scope holder 104 instead of impacting the scope, thereby reducing damage to the scope. By setting the rebound mechanism 103 below the scope holder 104, it simulates the forward return force of a firearm's recoil spring. When testing, the drive mechanism 102 impacts... The scope holder 104 moves downward, causing the spring in the return mechanism 103 to contract under pressure. After the spring contracts, it releases the elastic pressure, and the scope holder 104 moves upward. This elastic pressure mimics the thrust of a firearm's recoil spring returning to its original position. By testing the scope against impact and the recoil spring's forward return, the scope's testing accuracy is improved. Furthermore, during the recoil spring return test, when the drive mechanism 102 is activated, the scope holder 104 descends, causing the spring in the return mechanism 103 to... In the compressed state, the drive assembly is activated, and the transmission gear 115 drives the limiting shaft 106 to rotate on the fixed plate 105. Since the limiting shaft 106 does not shift when rotating on the fixed plate 105, and the threaded rod 107 is internally threaded onto the limiting shaft 106, the threaded rod 107 shifts while rotating inside the limiting shaft 106. This causes the support arm to slide in the middle of the support frame 101 via the connecting bearing 114, thereby allowing the limiting member 108 to engage with the sight. The end of the clamp 104 is limited so that after the output end of the drive mechanism 102 is reset, the support arm is driven to reset through the cooperation of the drive assembly, the limiting shaft 106 and the threaded rod 107. This allows the scope clamp 104 to reset under the restoring force of the return mechanism 103, completing the test of the impact of the thrust of the recoil spring of a firearm on the scope. By using the above mechanism, the problem of the drive mechanism 102 not resetting in time can be avoided, which would interfere with the reset of the scope clamp 104, making the test results of the scope more accurate.

[0036] Second embodiment: Based on the first embodiment, please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the limiting mechanism in the second embodiment. Figure 8 for Figure 7 A magnified view of the local structure at point B.

[0037] The present invention provides a scope testing device, which also includes a protective shell 201 and a heat sink 202.

[0038] In this specific embodiment, the fixed plate 105 is also provided with the protective shell 201. The protective shell 201 is disposed outside the output gear 111 and the transmission gear 115. The protective shell 201 protects the output gear 111 and the transmission gear 115 and prevents the external environment from affecting the meshing of the output gear 111 and the transmission gear 115.

[0039] The protective shell 201 is provided with an injection pipe 203. A sealing plug 204 is provided at one end of the injection pipe 203 away from the protective shell 201. The sealing plug 204 is removed, and gear lubricating oil is injected into the interior of the protective shell 201 through the injection pipe 203, thereby reducing the wear at the meshing point of the output gear 111 and the transmission gear 115.

[0040] Secondly, a heat sink 202 is provided on the side wall of the fixed section 112, and a heat sink 205 is provided on the heat sink 202. The heat sink 205 corresponds to the servo motor 117. The heat sink 205 allows the interior of the fixed section 112 to circulate with the outside air, thereby carrying away the heat generated by the servo motor 117 when it is working.

[0041] In addition, a slot 206 is provided at one end of the heat sink 202 extending to the outside of the fixed section 112. The slot 206 passes through the heat sink 205. A filter screen 207 is provided at the slot 206. The filter screen 207 can filter dust in the air and prevent excessive dust from entering the interior of the fixed section 112 through the heat sink 205.

[0042] When using a scope testing device according to this embodiment, the protective shell 201 protects the output gear 111 and the transmission gear 115, preventing the external environment from affecting the meshing of the output gear 111 and the transmission gear 115. Furthermore, the heat dissipation groove 205 allows the interior of the fixed section 112 to circulate with the outside air, thereby carrying away the heat generated by the servo motor 117 during operation.

[0043] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
