[0025] Please refer to Figures 1 to 7 As shown, the utility model discloses an adapter bracket 100 connected between a main bracket 200 and a camera 300, which includes a first bracket 1 connected to the camera 300 and a second bracket 2 connected to the main bracket 200, and also includes a connecting component 3 arranged between the first bracket 1 and the second bracket 2. For convenience of description, please refer to Figure 6 In the installation state where the camera 300 is located directly above the main bracket 200, the X direction is called the horizontal direction, and the Y direction is called the vertical direction.

[0026] Please refer to Figure 3 The second bracket 2 has an arc space 220 and a plurality of first teeth 221, and the plurality of first teeth 221 are located in the arc space 220 and are continuous. Figure 4 , Figure 6 and Figure 7 The connecting assembly 3 includes an operating member 31 and a guide shaft member 32. The guide shaft member 32 is connected to the operating member 31 and to the first bracket 1. The operating member 31 has a second tooth 311. The operating member 31 is arranged along its axial direction ( Figure 6 When the operating member 31 moves toward the second bracket 2 along the axial direction (X direction in the figure), the second tooth 311 separates from the first tooth 221, and the first bracket 1 rotates relative to the second bracket 2. Figure 6 When the first bracket 1 is moved away from the second bracket 2 (in the X direction in the figure), the second tooth 311 meshes with the first tooth 221, and the first bracket 1 is locked. The continuity between the multiple first teeth 221 is to facilitate the transition of the first tooth 221 from the previous one to the next one when meshing. The utility model can separate the second tooth 311 from the first tooth 221 by pressing the operating member 31, and can rotate the first bracket 1 relative to the second bracket 2 to adjust the angle when the first bracket 1 is locked relative to the second bracket 2. The utility model does not require the use of tools for adjustment, and the operation is simple and can be performed by non-professionals, which greatly simplifies the angle adjustment of the gun camera 300.

[0027] Please refer to Figure 4 and Figure 6 The connecting assembly 3 also includes a sleeve 34 and an elastic member 33. The operating member 31 and the guide shaft member 32 are both in the axial direction of the operating member 31 ( Figure 6 The two guide shaft members 32 are symmetrically arranged on the X direction in the middle. The elastic member 33 is accommodated in the sleeve 34, and the number of the elastic members 33 is not limited to one or two. The ends of the two guide shaft members 32 away from the corresponding operating members 31 are against the elastic member 33. The two operating members 31 and the two guide shaft members 32 are symmetrically arranged to ensure that the first bracket 1 can be locked and separated relative to the left and right sides of the second bracket 2. When the left and right sides are locked, the first bracket 1 is stably installed on the second bracket 2; when the left and right sides are separated, the first bracket 1 can be rotated relative to the second bracket 2 to adjust the angle. The function of the sleeve 34 is to accommodate the elastic member 33 to ensure that the elastic deformation of the elastic member 33 is carried out within a limited space, that is, to ensure that the compression and rebound of the elastic member 33 are always not offset along the X direction.

[0028] Please refer to Figure 4 , Figure 6 and Figure 7The sleeve 34 includes a baffle 340, a first cylindrical portion 341 and a second cylindrical portion 342. The first cylindrical portion 341 and the second cylindrical portion 342 are located on opposite sides of the baffle 340. The first cylindrical portion 341 and the second cylindrical portion 342 each form a receiving space 3401. In a specific embodiment, there are two elastic members 33. The two elastic members 33 are respectively located in the corresponding receiving spaces 3401. The two guide shaft members 32 respectively extend into the receiving spaces 3401 and abut against the elastic members 33. The first cylindrical portion 341 and the second cylindrical portion 342 each have an opening 3402. The two elastic members 33 respectively enter the corresponding receiving spaces 3401 from the corresponding openings 3402. The baffle 340 functions to provide the two elastic members 33 with abutting positions when they are compressed. The two elastic members 33 can make the two operating members 31 on the left and right sides independent of each other, and the operations do not affect each other. In other embodiments, the elastic member 33 may be one, and the one elastic member 33 is disposed in the sleeve 34, and may also provide elastic force to the two operating members 31 and the two guide shaft members 32 symmetrically disposed on the left and right sides at the same time, but in the case of one elastic member 33, the baffle 340 does not need to be disposed in the sleeve 34. The two operating members 31 on the left and right sides are interdependent and affect each other through the one elastic member 33 disposed.

[0029] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The first bracket 1 includes a base 11 and two side portions 12 extending from both sides of the base 11, and the second bracket 2 includes a base plate 21 and two side plates 22 extending from both sides of the base plate 21. The two side portions 12 are respectively installed corresponding to the two side plates 22, and the arc space 220 is opened in the side plates 22; the side portion 12 has a through hole 120, and the through hole 120 is non-circular. The guide shaft member 32 includes a first rod portion 321, and the first rod portion 321 matches the shape of the through hole 120. The first rod portion 321 is penetrated through the through hole 120 and has an interference fit with the through hole 120, and the operating member 31 is connected to the first rod portion 321. The interference fit is used to limit the guide shaft member 32 to slide only in the X direction relative to the first bracket 1, that is, manually pressing the operating member 31 can drive the guide shaft member 32 to press the elastic member 33. That is to say, the first bracket 1 can be rotated only when the second tooth 311 is separated from the first tooth 221; and the specific position of the meshing between the second tooth 311 and the first tooth 221 can be adjusted by rotating the first bracket 1 when the first bracket 1 cannot be rotated on the guide shaft 32. That is, only interference fit can adjust the installation angle between the first bracket 1 and the second bracket 2. It can also be understood that the inner wall surface of the through hole 120 and the cross-section of the outer surface of the first rod portion 321 are both non-circular shapes (hexagonal design is adopted in the specific implementation method), and the main purpose is to prevent the adjustment failure caused by the rotation of the shaft after the angle is adjusted.

[0030] Please continue to refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The connecting assembly 3 also includes two fixing members 35. The free end of the first rod portion 321 is provided with a notch 3210, and the operating member 31 is provided with a through hole 310. The fixing member 35 passes through the through hole 310 and is positioned in the notch 3210 to fix the operating member 31 on the corresponding first rod portion 321. In a specific embodiment, the inner surface of the through hole 310 is also correspondingly set to a hexagonal shape, so that the free end of the first rod portion 321 extends into the inner surface of the through hole 310 for pre-positioning; the function of the fixing member 35 is to completely fix the operating member 31 and the guide shaft member 32 to ensure that the two are not separated.

[0031] Please continue to refer to Figure 4 The guide shaft 32 further includes a second rod portion 322. The second rod portion 322 extends integrally with the first rod portion 321, and the cross section of the second rod portion 322 along the Y direction is circular. The second rod portion 322 presses the elastic member 33 to enable the elastic member 33 to deform.

[0032] Please refer to Figure 3 and Figure 4 The utility model adapter bracket 100 also includes a rotating shaft 5. The side plate 22 is provided with a first shaft hole 2200, and the side portion 12 is provided with a second shaft hole 1200. The rotating shaft 5 is inserted into the first shaft hole 2200 and the second shaft hole 1200. The operating member 31 is arranged along its axial direction ( Figure 6 When the first bracket 1 is close to the second bracket 2 (in the X direction), the first bracket 1 rotates relative to the second bracket 2 around the rotation axis 5, that is, the rotation axis 5 provides a center fulcrum for the rotation, and the arc space 220 provides an arc trajectory for the rotation.

[0033] Please refer to Figure 3 and Figure 7 The side portion 12 includes a main body 121 and a recess 122 formed by being recessed inward from the middle of the main body 121. The main body 121 is located on the inner side of the side plate 22, and the operating member 31 is disposed along the axial direction ( Figure 6 When the second tooth 311 approaches the second bracket 2 in the X direction, the second tooth 311 enters the clearance groove 122, that is, the clearance groove 122 provides the user with the possibility of pressing the operating member 31 inward; the through hole 120 is provided on the bottom wall of the clearance groove 122, so that the guide shaft member 32 passes through the first bracket 1 from the middle position of the clearance groove 122. The first shaft hole 2200 is located at the lower position of the arc space 220, and correspondingly, the second shaft hole 1200 is located at the lower position of the through hole 120.

[0034] Please refer to Figure 4 , Figure 6 and Figure 7The guide shaft 32 also has Figure 6 In the axial direction shown by the X direction, the guide shaft member 32 also has a supporting portion 323 protruding outward in the radial direction. Figure 6 In the X direction), the first rod portion 321 is located on one side of the side portion 12 and the abutting portion 323 is located on the other side of the side portion 12. Figure 6 In the figure, the abutting portion 323 protruding radially outwardly is shown as a surface protruding "upward" and "downward" from the guide shaft member 32. The abutting portion 323 firstly serves as a boundary between the first rod portion 321 and the second rod portion 322. The more important function of the abutting portion 323 is that when the abutting portion 323 abuts against the clearance groove 122, it can provide a stopping effect during the process of releasing the elastic force of the elastic member 33.

[0035] Please refer to Figures 1 to 3 and Figure 6 The adapter bracket 100 of the utility model also includes a connection assembly 4 for positioning and connecting the second bracket 2 to the main bracket 200.

[0036] For details, please refer to Figure 3 The connection assembly 4 includes a toothed disc 40 connected to the main bracket 200. The second bracket 2 includes a base plate 21 connected to the main bracket 200. The upper portion of the toothed disc 40 passes through the base plate 21 to limit the position of the second bracket 2. The position here refers to the horizontal direction ( Figure 6 The lower part of the toothed disc 40 is provided with a plurality of third teeth 401 and the plurality of third teeth 401 are arranged in a ring, and the substrate 21 has fourth teeth 211, along the axial direction ( Figure 6 In the Y direction in the figure, when the second bracket 2 is relatively far away from the toothed disc 40, the fourth tooth 211 is separated from the third tooth 401, and the second bracket 2 rotates relative to the main bracket 200. When the second bracket 2 is relatively close to the toothed disc 40, the fourth tooth 211 is meshed with the third tooth 401, and the second bracket 2 is locked. The utility model can also separate the fourth tooth 211 from the third tooth 401 by pressing the second bracket 2, and can rotate the second bracket 2 relative to the main bracket 200 to adjust the angle of the second bracket 2 when it is locked relative to the main bracket 200 in the horizontal plane.

[0037] Further references Figure 3 The surface of the base plate 21 protrudes upward to form a raised portion 212. A storage space is formed below the raised portion 212, and the lower portion of the toothed disc 40 is located in the storage space. The fourth tooth 211 is provided at the edge of the base plate 21 facing the storage space, and the upper portion of the toothed disc 40 passes through the raised portion 212 to further limit the position of the second bracket 2 in the horizontal direction (X direction).

[0038] Please refer to further Figure 3 Combined with Figure 6 The connection assembly 4 further includes a fixing element 41, an elastic element 42 and a limiting gasket 43. The fixing element 41 includes a cap 411 at the end and a rod-shaped portion 412 extending integrally from the cap 411. The limiting gasket 43 and the protrusion 212 are respectively located on opposite sides of the elastic element 42 to limit the elastic element 42. The rod-shaped portion 412 passes through the limiting gasket 43, the elastic element 42, the protrusion 212 and the toothed disc 40 and is connected to the main bracket 200 to fix the toothed disc 40 on the main bracket 200. The cap 411 abuts against a side of the limiting gasket 43 that is away from the elastic element 42. Because the radius of the cap portion 411 is small, a limiting gasket 43 is required to connect and abut the cap portion 411 at the end of the fixing element 41 with the elastic element 42; if the radius of the cap portion 411 is larger than the spiral radius of the elastic element 42, the limiting gasket 43 may not be provided, and the upper end of the elastic element 42 can directly abut against the lower surface of the cap portion 411 for limiting.

[0039] The working principle of the adapter bracket 100 of the utility model for adjusting the camera 300 in the vertical direction is as follows: the operator presses the operating members 31 on the left and right sides to separate the meshing teeth between the second teeth 311 and the plurality of first teeth 221, and the separation is unlocking, so that the installation angle of the first bracket 1 on the second bracket 2 can be adjusted; when the operating member 31 is pressed, the operating member 31 pushes the guide shaft members 32 on each side to move toward the middle to press the two elastic members 33 against the baffle 340, so that the elastic members 33 have elastic force; and after adjusting the installation angle, the operating member 31 is released to release the elastic force of the elastic member 33, and the elastic member 33 pushes the guide shaft member 32 and then pushes the second teeth 311 on the operating member 31, so as to re-engage the second teeth 311 with other teeth of the plurality of first teeth 221, and the engagement is locking, so that the first bracket 1 after the angle adjustment can be re-fixed on the second bracket 2. Therefore, the adapter bracket 100 of the present invention can achieve the angle adjustment of the camera 300 in the vertical direction, that is, the adjustment of the pitch angle of the camera 300.

[0040] The working principle of the adapter bracket 100 of the utility model for adjusting the camera 300 in the horizontal direction is as follows: the operator acts on the second bracket 2, specifically, pushes the bottom surface of the base plate 21 of the second bracket 2 upward, so that the second bracket 2 and the first bracket 1 above the second bracket 2, the connecting assembly 3 and the camera 300 are moved upward a certain distance as a whole. It should be noted that because the fixing element 41 is fixed to the toothed disc 40 and the toothed disc 40 is fixed to the main bracket 200, the connecting assembly 4 does not move upward. Because of the upward movement of the second bracket 2, the fourth tooth 211 provided on the second bracket 2 can be separated from the third tooth 401 fixed on the main bracket 200, and the separation is unlocking. At this time, the second bracket 2 and the entirety above the second bracket 2 (including the camera 300) can be rotated in the horizontal direction to adjust the angle in the horizontal direction. Because the second bracket 2 will compress the elastic element 42 when it moves upward relative to the fixing element 41, the elastic element 42 is clamped between the cap 411 and the protrusion 212 to provide elastic force in the Y direction; when the camera 300 is adjusted in the horizontal direction, the elastic recovery force of the elastic element 42 can be released, so that the fourth tooth 211 can be engaged with other teeth in the third tooth 401, and the engagement is locked, that is, the second bracket 2 is locked with the main bracket 200 again. Therefore, the adapter bracket 100 of the utility model can realize the angle adjustment of the camera 300 in the horizontal direction, that is, the angle adjustment of 360-degree rotation in the horizontal plane.

[0041] Firstly, the utility model can separate the second tooth 311 from the first tooth 221 by pressing the operating member 31, so that the first bracket 1 can be rotated relative to the second bracket 2 to adjust the angle when the first bracket 1 is locked relative to the second bracket 2; secondly, the utility model can separate the fourth tooth 211 from the third tooth 401 by acting on the base plate 21 and pushing the second bracket 2 upward, so that the second bracket 2 can be rotated relative to the main bracket 200 to adjust the angle when the second bracket 2 is locked relative to the main bracket 200. The utility model does not require the use of tools for adjustment, and the operation is simple and can be performed by non-professionals, which greatly simplifies the angle adjustment of the gun camera 300. The adapter bracket 100 of the utility model can adjust the angle of the camera 300 fixedly installed above it in both the vertical and horizontal directions. Therefore, the adapter bracket 100 of the utility model can also be called a universal adapter bracket.

[0042] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
