[0023] 3. This utility model provides an angle-adjustable aiming device. Compared with the existing relatively complex transmission structure, by using the ball as a connecting component, the structure of the aiming device can be simplified and the manufacturing cost can be reduced. Moreover, during the assembly process, the ball only needs to be placed between the first arc-shaped groove and the second arc-shaped groove to achieve the rotational connection between the carrier component and the cover, thereby greatly reducing the assembly difficulty and assembly time, improving assembly efficiency, and also improving the convenience of disassembly and assembly during subsequent maintenance and repair.

[0037] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0038] Reference Figures 1 to 5 An example of this utility model provides an angle-adjustable aiming device, which includes a housing 1, a carrier assembly 2, and an adjustment mechanism.

[0039] The outer shell 1 includes a shell 11 and a cover 12. The cover 12 is connected to one end of the shell 11 and has an emission hole.

[0040] Furthermore, the carrier assembly 2 is disposed inside the housing 11. A first arc-shaped groove is provided in the middle of one end of the carrier assembly 2, and a second arc-shaped groove is provided in the middle of the inner side of the cover 12. The first arc-shaped groove and the second arc-shaped groove are rotatably connected by a ball 3. The other end of the carrier assembly 2 is connected to the housing 11 by a first elastic member 4. The first elastic member 4 can provide a clamping force so that the carrier assembly 2 always presses the ball 3 tightly on the cover 12. A laser emitting head 21 is provided at one end of the carrier assembly 2 near the cover 12. The laser emitting head 21 corresponds to the emitting hole, and the light from the laser emitting head 21 is emitted through the emitting hole.

[0041] Furthermore, the adjustment mechanism is used to adjust the light emission angle of the laser emitting head 21, including a first adjustment component 5, a second adjustment component 6, and a second elastic element 7. The second elastic element 7 is located between the carrier component 2 and the housing 11 and is used to elastically support the carrier component 2. The first adjustment component 5 and the second adjustment component 6 are respectively installed on adjacent sides of the housing 11. The first adjustment component 5 is used to drive the carrier component 2 to swing up and down around the sphere 3, and the second adjustment component 6 is used to drive the carrier component 2 to swing left and right around the sphere 3.

[0042] When it is necessary to adjust the vertical angle of the emitted light, the first adjustment component 5 is operated and a force is applied to the carrier component 2, causing the carrier component 2 to swing up and down around the sphere 3. The laser emitting head 21 installed on the end of the carrier component 2 near the cover 12 will also swing up and down accordingly. At the same time, the second adjustment component 6 limits one side of the carrier component 2, and the second elastic element 7 always provides elastic support for the carrier component 2. The first elastic element 4 and the second elastic element 7 will generate corresponding elastic deformation according to the position change of the carrier component 2 to ensure the stability of the carrier component 2 during swing.

[0043] When it is necessary to adjust the left and right angle of the emitted light, the second adjustment component 6 is operated and a force is applied to the carrier component 2, causing the carrier component 2 to swing left and right around the sphere 3. The laser emitting head 21 installed on the end of the carrier component 2 near the cover 12 will also swing left and right accordingly. At the same time, the first adjustment component 5 limits the other side of the carrier component 2, and the second elastic element 7 always provides elastic support for the carrier component 2. The first elastic element 4 and the second elastic element 7 will generate corresponding elastic deformation according to the position change of the carrier component 2 to ensure the stability of the carrier component 2 during swing.

[0044] This embodiment of the utility model, by setting the sphere 3 as a connecting component, has the following beneficial effects:

[0045] First, the sphere 3 can rotate flexibly between the first and second arc-shaped grooves, providing a pivot point for the swing of the carrier assembly 2. This allows the carrier assembly 2 to rotate flexibly in multiple directions around the sphere 3. Whether adjusting the vertical or horizontal angle, the sphere 3 can serve as a stable pivot point, ensuring smooth swing of the carrier assembly 2. This enables a wider range of angle adjustments and guarantees the flexibility and accuracy of the aiming device's angle adjustment.

[0046] Secondly, during the angle adjustment process, the carrier component 2 will be subjected to forces from the first adjustment component 5 and the second adjustment component 6. The ball 3 can evenly distribute the forces to the contact surface of the first arc-shaped groove and the second arc-shaped groove, thereby reducing local stress concentration, avoiding damage to components due to excessive stress, and extending the service life of the aiming device.

[0047] Third, compared with the existing relatively complex transmission structure, by using the ball 3 as a connecting component, the structure of the aiming device can be simplified and the manufacturing cost reduced. Moreover, during the assembly process, the ball 3 only needs to be placed between the first arc-shaped groove and the second arc-shaped groove to achieve the rotational connection between the carrier component 2 and the cover 12, thereby greatly reducing the assembly difficulty and assembly time, improving assembly efficiency, and also improving the convenience of disassembly and assembly during subsequent maintenance and repair.

[0048] In some preferred embodiments, a limiting block 22 is provided on one side of the carrier component 2, the limiting block 22 is provided with a U-shaped groove 221, a pin 121 is provided on the inner side of the cover 12, the pin 121 is located directly below the ball 3, the pin 121 extends axially along the vertical direction of the cover 12, and the pin 121 is located in the U-shaped groove 221.

[0049] Understandably, during the adjustment of the left and right angles of the emitted light, the carrier component 2 swings left and right around the sphere 3, causing the limiting block 22 installed on one side of the carrier component 2 to swing left and right accordingly. The U-shaped groove 221 on the limiting block 22 swings around the axis of the pin 121, thereby ensuring that the carrier component 2 swings left and right along the same axis and improving the angle adjustment accuracy. During the adjustment of the up and down angles of the emitted light, the carrier component 2 swings up and down around the sphere 3, causing the limiting block 22 installed on one side of the carrier component 2 to swing up and down accordingly. The U-shaped groove 221 on the limiting block 22 can limit the pin 121, thereby preventing the carrier component 2 from shifting during the up and down swing and further improving the angle adjustment accuracy.

[0050] In some preferred embodiments, the first elastic element 4 is a first spring, the housing 11 is provided with a first boss 111, the carrier assembly 2 is provided with a second boss 23, and the two ends of the first spring abut against the first boss 111 and the second boss 23 respectively.

[0051] Understandably, the first boss 111 and the second boss 23, as an integrated structure of the housing 11 and the carrier assembly 2, do not require additional fasteners, simplifying the installation process of the first spring and reducing assembly difficulty. Moreover, the first boss 111 and the second boss 23 provide a fixed installation reference for the first spring, ensuring that the compression and rebound path of the first spring always proceeds in the predetermined direction, avoiding deviation or twisting, and improving the stability of the overall structure.

[0052] In some preferred embodiments, the first adjustment component 5 and the second adjustment component 6 have the same structure. The first adjustment component 5 includes an adjustment screw 51 and an adjustment knob 52. The adjustment screw 51 is threadedly connected to the housing 11. The end of the adjustment screw 51 abuts against one side of the carrier component 2. The adjustment knob 52 is used to drive the adjustment screw 51 to engage with the housing 11.

[0053] Understandably, on the one hand, the first adjusting component 5 and the second adjusting component 6 have the same structure, which simplifies the production and processing of parts, reduces the types of parts and the difficulty of assembly. On the other hand, by rotating the adjusting knob 52, the adjusting knob 52 drives the adjusting screw 51 to engage with the housing 11, which can convert the rotational movement of the adjusting knob 52 into the axial linear displacement of the adjusting screw 51, so that one end of the adjusting screw 51 abuts against one side of the carrier component 2, which improves the accuracy of the angle adjustment of the carrier component 2. At the same time, the adjusting screw 51 has a self-locking characteristic when it is threaded with the housing 11. After the end of the adjusting screw 51 abuts against the carrier component 2, the thread friction can prevent the carrier component 2 from being displaced due to vibration or external force, ensuring that the adjusted angle is stably locked.

[0054] In some preferred embodiments, one end of the adjusting screw 51 is provided with an inner polygonal groove 511, the center of the adjusting knob 52 is provided with a rotating rod 521, and the end of the rotating rod 521 is provided with a limiting protrusion 522, which cooperates with the inner polygonal groove 511.

[0055] Understandably, on the one hand, by setting the adjusting screw 51 and the adjusting knob 52 separately, the two parts can be disassembled and installed independently. When one part is damaged, only the damaged part needs to be replaced, thereby reducing maintenance costs. On the other hand, after the limiting protrusion 522 is inserted into the inner polygonal groove 511, the inner polygonal groove 511 and the limiting protrusion 522 cooperate to achieve a gapless connection between the adjusting screw 51 and the adjusting knob 52, ensuring that the rotational force is efficiently transmitted to the adjusting screw 51 and avoiding adjustment errors caused by slippage during operation.

[0056] It should be noted that the inner polygonal groove 511 can also be an inner triangular groove, an inner quadrangular groove, an inner pentagonal groove, an inner hexagonal groove, etc. The specific shape is not limited in this embodiment.

[0057] Furthermore, an annular groove is provided on the outer periphery of the rotating rod 521, and an E-type clip 53 is engaged in the annular groove. The E-type clip 53 protrudes from the outer periphery of the rotating rod 521. A threaded pressure ring 54 is threadedly connected to the housing 11. A through hole for the rotating rod 521 to pass through is provided in the center of the threaded pressure ring 54. The threaded pressure ring 54 is used to limit the E-type clip 53 on the housing 11. The end of the rotating rod 521 is used to limit the top of the adjusting screw 51.

[0058] It is understandable that by embedding the E-type clip 53 into the annular groove of the rotating rod 521, and connecting the threaded pressure ring 54 to the housing 11 through the thread, the E-type clip 53 is limited on the housing 11, and the rotating rod 521 is physically limited by the E-type clip 53, effectively preventing the adjustment knob 52 from dislodging from the housing 11.

[0059] Furthermore, an annular gasket 55 is provided between the housing 11 and the threaded pressure ring 54. The top of the annular gasket 55 is provided with an annular protrusion, and the bottom end of the threaded pressure ring 54 is provided with a stepped groove. The large end of the stepped groove presses the outer edge of the annular gasket 55 onto the housing 11, and the small end of the stepped groove limits the E-type clip 53 to the top of the annular protrusion. The inner edge of the annular gasket 55 is located between the end of the rotating rod 521 and the top of the adjusting screw 51, and the annular protrusion is located between the inner side of the threaded pressure ring 54 and the outer side of the rotating rod 521.

[0060] Understandably, the stepped groove of the threaded pressure ring 54 and the annular protrusion on the annular washer 55 respectively limit and support the upper and lower sides of the E-type clip 53, which can prevent the E-type clip 53 from being deformed when the adjustment knob 52 is rotated, thereby improving the stability and reliability of the overall structure and extending the service life of the aiming device.

[0061] In some preferred embodiments, a through hole is provided in the housing 11, with one end of the through hole facing the adjustment knob 52 and the other end facing the cover 12. A clamping rod 56 and a second spring 57 are provided in the through hole. Ball bearings 58 are provided at both ends of the second spring 57, and one of the ball bearings 58 abuts against the outer side of the adjustment knob 52.

[0062] Understandably, the second spring 57 applies elastic pressure to the adjustment knob 52 through the ball bearing 58 at its end to form stable frictional damping, thereby preventing the adjustment knob 52 from rotating unexpectedly due to vibration or external force, and ensuring that the adjusted angle is stably locked.

[0063] Moreover, during the assembly process, the clamping rod 56, the second spring 57 and the ball 58 are integrated into the through hole, and the clamping rod 56 is limited by the cover body 12. The assembly can be completed by elastic pre-tightening, thereby reducing the assembly difficulty.

[0064] In some preferred embodiments, a triangular prism 24 is provided at the end of the carrier assembly 2 away from the laser emitter 21, the second elastic element 7 is a third spring, one end of the third spring abuts against the inner wall of the housing 11, and the other end of the third spring abuts against one side of the triangular prism 24, and the adjusting screws 51 in the first adjusting assembly 5 and the second adjusting assembly 6 abut against the other two sides of the triangular prism 24 respectively.

[0065] It is understandable that the three sides of the triangular prism 24 correspond to the elastic support of the third spring and the contact points of the adjusting screws 51 in the first and second adjusting components 6, forming a three-dimensional force structure. The third spring provides a reverse elastic force during the adjustment process. When the adjusting screws 51 release the pressure, the spring pushes the triangular prism 24 to reset. By adjusting the contact force of the adjusting screws 51 on the two sides, the swing direction of the carrier component 2 around the sphere 3 can be precisely controlled, realizing the independence and coordination of multi-dimensional angle adjustment.

[0066] Furthermore, the inner wall of the housing 11 is provided with a first limiting groove 112, and one side of the triangular prism 24 is provided with a second limiting groove 241. The first limiting groove 112 and the second limiting groove 241 respectively accommodate the two ends of the third spring.

[0067] It is understandable that the first limiting groove 112 and the second limiting groove 241 provide precise installation positions for the two ends of the third spring, preventing the third spring from detaching or shifting, ensuring that the compression and rebound of the third spring always proceed in the predetermined direction, and avoiding lateral offset that could lead to angle adjustment errors.

[0068] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
