Description

Camera fixing device TECHNICAL FIELD

[0001] The present application relates to a fixing device, in particular to a camera fixing device for fixing a camera and capable of being clamped on an object for use. BACKGROUND

[0002] Modern people, whether professionals or the general public, widely use cameras or mobile phones to capture beautiful images in life. With the popularization and diversification of cameras, many camera fixing devices have been developed to facilitate users to take pictures. Common camera fixing devices are divided into handheld and fixed types. The handheld type fixes the camera on the camera fixing device for the user to hold and take pictures. The fixed type fixes the camera on the camera fixing device for the user to place on the ground or table.

[0003] However, neither the handheld nor the fixed camera fixing device can be fixed to objects of different shapes and sizes, but only can be held or placed by the user. Therefore, when the user cannot take pictures by hand and the environment cannot be placed on the ground or flat surface, the user cannot take stable pictures and miss beautiful scenery. Therefore, how to make the camera fixing device capable of being held, placed, or fixed on an object according to different scene environments is a problem that needs to be improved for the current camera fixing device.

[0004] Therefore, the present applicant has made great efforts to solve the above problems by studying and applying the theory, which is the improvement goal of the present applicant.

[0036] The detailed description and technical content of the present application will be described below with reference to the accompanying drawings, however the accompanying drawings are only used for illustration purposes, and not used to limit the present application.

[0037] Referring to FIGS. 1-6, the present application provides a camera fixing device for fixing a camera A, and the camera fixing device is used for clamping on an object B. The camera A can be a camera or a mobile phone, and the present application is not limited thereto. Referring to FIGS. 7-9, the first embodiment of the present application is shown, and the camera fixing device mainly comprises a base 10, a main support 20, a fixed clamping arm 30, a movable clamping arm 40, and an adjusting mechanism 50.

[0038] The camera A is fixed on the base 10. Specifically, the camera A can be fixed on the base 10 by a connecting device C. In this embodiment, the connecting device C is a holder for fixing the camera A, but the present application is not limited thereto. For example, the connecting device C can also be a clamping mobile phone holder for fixing the camera A. The holder and the clamping mobile phone holder are both connecting devices C known to those skilled in the art. Although the clamping mobile phone holder is not shown in the drawings of the present application, the holder and the clamping mobile phone holder should both fall within the protection scope of the connecting device C of the present application. The connecting device C of the present application is not limited to the holder and the clamping mobile phone holder. Other forms of connecting devices C that can be used to fix the camera A should also fall within the protection scope of the present application.

[0039] The main support 20 is connected to the base 10. Specifically, the main support 20 is connected to the base 10 on the opposite side of the base 10 where the camera A is installed, i.e., the main support 20 and the camera A are located on opposite sides of the base 10 and do not interfere with each other. In this embodiment, the main support 20 is pivotally arranged on the base 10, so that the angle between the main support 20 and the base 10 can be adjusted, but the present application is not limited thereto. The main support 20 extends along a longitudinal direction D and has a long strip shape. Specifically, the main support 20 extends away from the base 10.

[0040] The fixed clamping arm 30 is arranged on one of the base 10 and the main support 20. In this embodiment, the fixed clamping arm 30 is arranged on the main support 20, but the present application is not limited thereto. Other arrangements of the fixed clamping arm 30 will be described in other embodiments, and thus will not be described here. The movable clamping arm 40 is movable along the longitudinal direction D, and the movable clamping arm 40 is arranged opposite to the fixed clamping arm 30.

[0041] The adjusting mechanism 50 is arranged on the main support 20. The adjusting mechanism 50 is capable of driving the movable clamping arm 40 to approach or move away from the fixed clamping arm 30 along the longitudinal direction D, so as to enable the movable clamping arm 40 to clamp or release the workpiece B together with the fixed clamping arm 30. In this way, the camera A is arranged and fixed by the base 10, and the movable clamping arm 40 is driven by the adjusting mechanism 50 to approach or move away from the fixed clamping arm 30, so as to enable the movable clamping arm 40 to clamp or release the workpiece B together with the fixed clamping arm 30. In this way, the camera holder can clamp the workpiece B of different diameters or different shapes according to different use environments, so as to enable the camera A to be stably photographed.

[0042] Further description, referring to FIG. 7, the main support 20 has a limiting groove 21 extending along the longitudinal direction D and located on the inner side of the main support 20. The adjusting mechanism 50 includes a sliding seat 51, a screw rod 52 and a driving assembly 53. The sliding seat 51 is accommodated in the limiting groove 21 and is limited by the limiting groove 21 on the opposite sides, so that the sliding seat 51 is limited in the limiting groove 21 and can only slide back and forth along the longitudinal direction D. The movable clamping arm 40 is arranged on the sliding seat 51, so as to be capable of sliding back and forth along the longitudinal direction D with the sliding seat 51. The screw rod 52 is rotatably arranged in the limiting groove 21. Specifically, one end of the screw rod 52 is rotatably inserted into the fixed hole 211 on the side of the limiting groove 21 facing the base 10. The screw rod 52 penetrates the sliding seat 51, and the screw rod 52 is screwed to the threaded hole 511 of the sliding seat 51 through the external thread 521 on the outer surface thereof. In this way, since the two sides of the sliding seat 51 are limited by the limiting groove 21, when the screw rod 52 rotates, the threaded hole 511 of the sliding seat 51 can be driven by the external thread 521 of the screw rod 52 to make the sliding seat 51 slide along the longitudinal direction D. The driving assembly 53 is connected to the other end of the screw rod 52 (i.e. the end of the screw rod 52 away from the base 10). When the driving assembly 53 is rotated, the driving assembly 53 drives the screw rod 52 to rotate, so as to make the sliding seat 51 drive the movable clamping arm 40 to approach the fixed clamping arm 30. When the driving assembly 53 is reversely rotated, the driving assembly 53 drives the screw rod 52 to reverse, so as to make the sliding seat 51 drive the movable clamping arm 40 to move away from the fixed clamping arm 30.

[0043] In the present embodiment, the adjusting mechanism 50 further comprises a limiting piece 54, and the driving assembly 53 comprises a rotating base 531 and a locking lever 532. The limiting piece 54 is fixed between the end of the main support 20 (i.e. the end of the main support 20 away from the base 10) and the rotating base 531. The limiting piece 54 has a stop notch 541. The rotating base 531 is connected to the end of the screw rod 52 away from the base 10, and the rotating base 531 is rotatably connected to the limiting piece 54. The locking lever 532 is pivotally connected to the rotating base 531, so as to be able to pivot relative to the rotating base 531. In this way, when the locking lever 532 is pivoted to be located in the stop notch 541, the locking lever 532 is limited and stopped by the limiting piece 54, so that the driving assembly 53 cannot be rotated, thereby locking the position of the movable clamping arm 40; when the user needs to adjust the position of the movable clamping arm 40, the user only needs to pivot the locking lever 532 out of the stop notch 541, so as to rotate the driving assembly 53 to adjust the position of the movable clamping arm 40.

[0044] In addition, the fixed clamping arm 30 is pivotally arranged on one of the base 10 and the main support 20, and the movable clamping arm 40 is pivotally arranged on the sliding base 51. Therefore, the fixed clamping arm 30 and the movable clamping arm 40 are respectively capable of being pivoted and switched between a storage position S1 and a working position S2. As shown in FIGS. 1 and 2, when the fixed clamping arm 30 and the movable clamping arm 40 are located at the storage position S1, the fixed clamping arm 30 and the movable clamping arm 40 are parallel to the longitudinal direction D, so as to reduce the volume to achieve the storage effect. As shown in FIGS. 3 to 6, when the fixed clamping arm 30 and the movable clamping arm 40 are located at the working position S2, the fixed clamping arm 30 and the movable clamping arm 40 are substantially perpendicular to the longitudinal direction D, so that the fixed clamping arm 30 and the movable clamping arm 40 can clamp the working object B.

[0045] In the present embodiment, the fixed clamping arm 30 is pivotally connected to the main support 20, and the camera fixing device further comprises a pair of auxiliary supports 60. As shown in FIGS. 1 to 3 and 8 to 9, the main support 20 and each auxiliary support 60 are pivotally arranged on the base 10. Specifically, the main support 20 and each auxiliary support 60 are located on opposite sides of the base 10 relative to the camera A, and the main support 20 and each auxiliary support 60 are arranged at equal angles to form a triangular shape. Accordingly, as shown in FIGS. 1 and 9, when the main support 20 and each auxiliary support 60 are pivoted relative to the base 10 to be parallel to each other, the main support 20 and each auxiliary support 60 are stored in a rod-shaped structure, so as to facilitate the user to store and hold. As shown in FIGS. 2 and 8, when the main support 20 and each auxiliary support 60 are pivoted relative to the base 10 to be opened, the main support 20 and each auxiliary support 60 can form a tripod structure to enable the camera fixing device to be placed on the ground or other plane for use.

[0046] Further, the fixed clamping arm 30 comprises a first arm body 31, and the movable clamping arm 40 comprises a second arm body 41. Referring to FIGS. 5 and 6, the first arm body 31 has a first clamping groove 311, and the second arm body 41 has a second clamping groove 411. The first clamping groove 311 and the second clamping groove 411 can jointly clamp the outer edge of the workpiece B. Specifically, the first clamping groove 311 and the second clamping groove 411 in the embodiment are both approximately V-shaped inwardly concave, and thus can clamp the workpiece B with an outer edge cross section not having parallel sides (for example, the outer edge cross section is circular, elliptical, triangular, irregular, etc.), such as a rod, a jagged object, etc. However, the shapes of the first clamping groove 311 and the second clamping groove 411 are not limited to V-shaped, and can also be circular arc or irregular concave grooves.

[0047] In addition, the fixed clamping arm 30 further comprises a first clamping block 32 pivotally arranged on the first arm body 31, and the movable clamping arm 40 further comprises a second clamping block 42 pivotally arranged on the second arm body 41. The first clamping block 32 has a first clamping plane 321, and the second clamping block 42 has a second clamping plane 421. In this way, the user can pivot the first clamping block 32 and the second clamping block 42 according to the needs, so as to adjust the first clamping block 32 and the second clamping block 42 for different outer edges of the workpiece B. Specifically, as shown in FIGS. 3 and 4, when the outer edge cross section of the workpiece B has parallel sides (for example, the outer edge cross section is rectangular or regular polygon), such as a table board, a block or a plate object, etc., the user can pivot the first clamping block 32 and the second clamping block 42 to make the first clamping plane 321 parallel to and relative to the second clamping plane 421, so that the first clamping plane 321 and the second clamping plane 421 can jointly clamp the opposite two sides of the workpiece B which are parallel to each other.

[0048] Please continue to refer to FIG. 10 and FIG. 11, which show the second embodiment of the present application. The main difference between the second embodiment and the first embodiment is that the fixed clamping arm 30 is pivotally connected to the center of the base 10. The details are as follows. In the second embodiment, the fixed clamping arm 30 and the camera A are located on opposite sides of the base 10, and the main support 20 and each auxiliary support 60 are pivotally connected to the base 10 and collectively surround the fixed clamping arm 30. Therefore, as shown in FIG. 11, when the main support 20 and each auxiliary support 60 are pivoted relative to the base 10 to be parallel to each other, the main support 20 and each auxiliary support 60 are still stored in a rod-shaped structure for easy storage and gripping by the user, and the fixed clamping arm 30 is located between the main support 20 and each auxiliary support 60 without affecting the storage of the main support 20 and each auxiliary support 60. As shown in FIG. 10, when the main support 20 and each auxiliary support 60 are pivoted relative to the base 10 to be open, the main support 20 and each auxiliary support 60 can form a tripod structure to enable the camera holder to be placed on the ground or other flat surfaces for use, and the fixed clamping arm 30 can be pivoted to the working position S2 as needed to clamp and fix the workpiece B together with the movable clamping arm 40.

[0049] Please continue to refer to FIG. 12 and FIG. 13, which show the third embodiment of the present application. The main difference between the third embodiment and the first embodiment is that the fixed clamping arm 30 is pivotally connected to the base 10, and each auxiliary support 60 is pivotally connected to the fixed clamping arm 30. The details are as follows. In the third embodiment, the fixed clamping arm 30 and the main support 20 are pivotally connected to the base 10 opposite each other and located on opposite sides of the base 10 relative to the camera A, and each auxiliary support 60 is pivotally connected to one end of the fixed clamping arm 30 away from the base 10. Therefore, as shown in FIG. 13, when the main support 20 is pivoted relative to the base 10 and each auxiliary support 60 is pivoted relative to the fixed clamping arm 30 to be parallel to each other, the main support 20 and each auxiliary support 60 are still stored in a rod-shaped structure for easy storage and gripping by the user, and the movable clamping arm 40 is stored in the first clamping groove 311 of the fixed clamping arm 30 without affecting the storage of the main support 20 and each auxiliary support 60. As shown in FIG. 12, when the main support 20, the fixed clamping arm 30, and each auxiliary support 60 are pivoted relative to the base 10 to be open, the main support 20, the fixed clamping arm 30, and each auxiliary support 60 can form a tripod structure to enable the camera holder to be placed on the ground or other flat surfaces for use. That is, the fixed clamping arm 30 can not only be used as part of the tripod, but also be pivoted to the working position S2 as needed to clamp and fix the workpiece B together with the movable clamping arm 40.

[0050] Further explanation, please refer to FIG. 3 to FIG. 9, the first clamping block 32 and the second clamping block 42 in the first embodiment of the present application each have a pair of first pivot joints 322 and a pair of second pivot joints 422. In the fixed clamping arm 30, each first pivot joint 322 is sleeved and pivoted to the opposite sides of the first arm body 31. In the movable clamping arm 40, each second pivot joint 422 is sleeved and pivoted to the opposite sides of the second arm body 41. However, the present application is not limited to the above, for example, FIG. 14 shows the fourth embodiment of the present application, which is different from the first embodiment in that the first clamping block 32 and the second clamping block 42 each have only one first pivot joint 322 and one second pivot joint 422. Specifically, the first pivot joint 322 of the fourth embodiment is inserted and pivoted to one end of the first arm body 31 away from the main bracket 20, and the second pivot joint 422 is inserted and pivoted to one end of the second arm body 41 away from the main bracket 20. In other words, the difference between the first embodiment and the fourth embodiment is only in the pivoting manner of the first clamping block 32 and the second clamping block 42, so both embodiments should fall within the scope of protection of the present application, and the first clamping block 32 and the second clamping block 42 can of course also adopt other unmentioned pivoting manners, but all should be simple changes that can be made by those skilled in the art according to needs, so they should still fall within the scope of protection of the present application, which is hereby stated.

[0051] The camera fixing device of the present application fixes the camera A through the base 10, and drives the movable clamping arm 40 to approach or move away from the fixed clamping arm 30 by the adjusting mechanism 50, so that the movable clamping arm 40 and the fixed clamping arm 30 can jointly clamp or release the workpiece B, so that the camera fixing device can clamp different workpieces B of different outer diameters or different shapes according to different use environments, and the camera A can be stably photographed.

[0052] In summary, the foregoing disclosure of the present application is intended to enable those skilled in the art to clearly understand the technical content of the present application and to implement it, and is not intended to limit the scope of patent protection of the present application. In addition, the present application can of course have other unlisted embodiments, and those skilled in the art should be able to evolve various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all fall within the scope of protection of the present application.
