Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a photographic equipment clamp. Background Technology

[0002] Photographic equipment clamps are commonly used in photographic equipment. In these technologies, the clamping structure of a photographic equipment clamp directly clamps and locks the target object through the interaction of a locking nut and a clamping part. For example, during use, rotating the locking nut forward clamps and locks the target object, while rotating it in the opposite direction separates it from the target object. Because the locking nut is in direct contact with the target object, movement or shaking during use can easily cause the locking nut to rotate. For instance, if the target object causes the locking nut to rotate in the opposite direction, it can loosen the locking nut, leading to a loosening of the clamp. Utility Model Content

[0003] The purpose of this invention is to disclose a photographic equipment clamp. An anti-loosening component is disposed between a locking component and a clamping end. A target object can be placed between the anti-loosening component and the clamping end. The locking component moves the anti-loosening component closer to the clamping end, thereby clamping the target object. When the target object moves or shakes during use, the anti-loosening component separates the target object from the locking component, and the anti-loosening component and the connecting component move in a straight line relative to each other. The target object will not cause the anti-loosening component to rotate, and consequently, the target object will not cause the locking component to rotate, thereby improving the clamping stability of the target object by this invention.

[0012] As an optional implementation, the locking member is provided with a first locking part, and the anti-loosening member is provided with a second locking part;

[0013] The first locking part and the second locking part are locked together in the axial direction, and the first locking part and the second locking part are rotatably connected in the radial direction.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0041] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0042] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0043] See Figures 1 to 10 This utility model discloses a camera equipment clamp, comprising: a connector 10, which includes a first body 101 and a clamping end 102 extending outward, the first body 101 and the clamping end 102 being interconnected; a locking member 20, which is movably connected to the connector 10 and moves spirally relative to the first body 101; and an anti-loosening member 30, which is movably connected to the connector 10 and moves linearly relative to the connector 10; the anti-loosening member 30 is disposed between the locking member 20 and the clamping end 102, and the locking member 20 drives the anti-loosening member 30 to approach the clamping end 102.

[0044] In this invention, the anti-loosening component 30 is disposed between the locking component 20 and the clamping end 102. The target object can be placed between the anti-loosening component 30 and the clamping end 102. The locking component 20 drives the anti-loosening component 30 to move closer to the clamping end 102, thereby clamping the target object. When the target object moves or shakes during use, the anti-loosening component 30 separates the target object from the locking component 20, and the anti-loosening component 30 and the connecting component 10 move in a straight line relative to each other. The target object will not drive the anti-loosening component 30 to rotate, and thus the target object will not drive the locking component 20 to rotate, thereby improving the clamping stability of the target object in this invention.

[0045] It should be noted that the first main body 101 and the clamping end 102 are integrally formed, or the first main body 101 and the clamping end 102 are separately formed and then connected and fixed into one by welding, bonding or other means.

[0046] In this embodiment of the utility model, the anti-loosening member 30 is provided with an anti-rotation hole 301. The anti-loosening member 30 is sleeved on the first body 101 through the anti-rotation hole 301. The first body 101 has a straight connecting part 103 arranged along its axial direction. The anti-loosening member 30 slides along the straight connecting part 103 on the first body 101 through the anti-rotation hole 301.

[0047] For example, see Figure 5 , Figure 7 , Figure 9 as well as Figure 10The anti-rotation hole 301 is an oblong hole shape and has a part for cooperating with the straight connecting part 103. The first body 101 can prevent the anti-loosening member 30 from rotating around the central axis of the first body 101 by providing the straight connecting part 103 to cooperate with the anti-rotation hole 301. Furthermore, the movement stability of the anti-loosening member 30 can be improved by increasing the number of straight connecting parts 103. The first body 101 is provided with two straight connecting parts 103 to increase the contact area between the anti-loosening member 30 and the first body 101. For example, the front and rear side walls of the first body 101 are provided with straight connecting parts 103.

[0048] Of course, in some other application scenarios, the anti-rotation hole 301 is a D-shaped hole, an arc-shaped hole, or an oblong hole, and at least one part of the anti-rotation hole 301 cooperates with the straight connecting part 103.

[0049] Continue reading Figure 9 as well as Figure 10 The mating surface between the anti-rotation hole 301 and the straight connecting part 103 is a flat mating surface; of course, in other embodiments, the mating surface between the anti-rotation hole 301 and the straight connecting part 103 can also be a toothed mating surface or an irregular mating surface. Using a toothed mating surface or an irregular mating surface further increases the contact area between the anti-loosening member 30 and the first body 101, thereby improving the smoothness of movement of the anti-loosening member 30.

[0050] In this embodiment of the utility model, the locking member 20 is provided with a threaded hole 201, and the locking member 20 is sleeved on the first body 101 through the threaded hole 201. The first body 101 is provided with a threaded connection part 104 arranged in its axial direction, and the locking member 20 is threadedly connected to the first body 101.

[0051] For example, see Figure 5 The threaded hole 201 on the locking member 20 is a full thread in the circumferential direction, while the threaded connection part 104 on the first body 101 corresponding to the locking member 20 is a discontinuous thread in the circumferential direction. Since the threaded hole 201 on the locking member 20 is a full thread in the circumferential direction, the locking member 20 can still be threadedly connected to the first body 101.

[0052] Furthermore, the first body 101 is provided with two threaded connection portions 104 to increase the contact area between the locking member 20 and the first body 101. For example, the left and right side walls of the first body 101 are provided with threaded connection portions 104. In other words, the smoothness of movement between the locking member 20 and the first body 101 can be improved by increasing the number of threaded connection portions 104.

[0053] See Figure 6Since both the threaded connection 104 and the straight connection 103 are provided on the first body 101, after the locking member 20 is sleeved on the first body 101, there is a first clearance gap between the straight connection 103 and the locking member 20. In other words, the setting position of the straight connection 103 needs to avoid interfering with the relative spiral movement of the locking member 20.

[0054] See Figure 7 In order to avoid interference between the threaded connection portion 104 and the relative linear movement of the anti-loosening member 30, the portion of the anti-rotation hole 301 corresponding to the threaded connection portion 104 has a second clearance gap with the threaded connection portion 104, or the portion of the anti-rotation hole 301 corresponding to the threaded connection portion 104 is provided along the outer contour of the threaded connection portion 104.

[0055] It should be noted that the anti-rotation hole 301 can be set at the central axis of the anti-loosening member 30, thereby minimizing the impact of the anti-rotation hole 301 on the structural strength of the anti-loosening member 30; the threaded hole 201 can be set at the central axis of the locking member 20, thereby minimizing the impact of the threaded hole 201 on the structural strength of the locking member 20; that is, the locking member 20, the anti-loosening member 30, and the first body 101 are coaxially arranged, thereby enabling the camera equipment clamp to have better structural strength.

[0056] In this embodiment of the utility model, the threaded connection portion 104 and the straight connection portion 103 are respectively disposed on adjacent side walls in the circumferential direction of the first main body 101.

[0057] For example, see Figure 6 as well as Figure 7 Since the threaded connection 104 and the straight connection 103 are respectively provided on adjacent side walls in the circumferential direction of the first body 101, for example, the front and rear side walls of the first body 101 are provided with straight connection 103, and the left and right side walls of the first body 101 are provided with threaded connection 104; the anti-loosening member 30 and the locking member 20 do not interfere with each other when moving along the axial direction of the first body 101, and both the anti-loosening member 30 and the locking member 20 can move along the axial direction of the first body 101.

[0058] In this embodiment of the utility model, the locking member 20 is provided with a first locking part 202, and the anti-loosening member 30 is provided with a second locking part 302; the first locking part 202 and the second locking part 302 are locked together in the axial direction, and the first locking part 202 and the second locking part 302 are rotatably connected in the radial direction.

[0059] With the cooperation of the first locking part 202 and the second locking part 302, the anti-loosening part 30 will not rotate with the locking part 20. However, the locking part 20 can drive the anti-loosening part 30 to move along the axis of the first body 101, thereby preventing the anti-loosening part 30 from separating from the locking part 20. When the anti-loosening part 30 and the locking part 20 separate, the user needs to operate the anti-loosening part 30 separately, which is inconvenient to use.

[0060] Based on the above structure, when using the camera equipment clamp, the user only needs to rotate the locking part 20, without having to operate the anti-loosening part 30 separately, which is convenient and quick.

[0061] In this embodiment of the utility model, the locking member 20 includes a second body 203 and a connecting body 204, the second body 203 and the connecting body 204 being connected to each other; the anti-loosening member 30 has a first recess 303 at the end facing the locking member 20, and a second snap-fit ​​portion 302 is provided in the first recess 303; the connecting body 204 is provided with the second snap-fit ​​portion 302, and the connecting body 204 is inserted into the first recess 303.

[0062] For example, see Figure 3 as well as Figure 4 The locking component 20 is nested with the anti-loosening component 30 through the connecting body 204, making the connection between the locking component 20 and the anti-loosening component 30 tighter. At the same time, through the cooperation of the first locking part 202 and the second locking part 302, the locking component 20 and the anti-loosening component 30 are integrated in appearance, making the overall structure more compact, the connection more stable, and the appearance more beautiful.

[0063] It should be noted that, since the connector 204 needs to be inserted into the first recess 303 and the first snap-fit ​​part 202 needs to cooperate with the second snap-fit ​​part 302, when the connector 204 is an integral ring structure, in order to facilitate the assembly of the locking part 20 and the anti-loosening part 30, the connector 204 can be made of a material that can undergo a certain elastic deformation, such as metal steel, metal iron, or PP plastic, etc., depending on the actual application scenario, without limitation, as long as the assembly of the locking part 20 and the anti-loosening part 30 can be completed.

[0064] Of course, in other embodiments, the connector 204 may also include multiple snap-fit ​​teeth, which are spaced apart and arranged circumferentially, so that the multiple snap-fit ​​teeth form a first snap-fit ​​portion 202, and each snap-fit ​​tooth can snap-fit ​​with the second snap-fit ​​portion 302; since the multiple snap-fit ​​teeth are arranged circumferentially, the first snap-fit ​​portion 202 formed by the multiple snap-fit ​​teeth can be rotatably connected to the second snap-fit ​​portion 302.

[0065] Since one end of the snap-fit ​​tooth is fixedly connected to the connector 204 and the other end of the snap-fit ​​tooth is a free end, the snap-fit ​​tooth can undergo a certain elastic deformation. For example, when the snap-fit ​​tooth is made of materials such as metal steel, metal iron or PP plastic, it is convenient for the connector 204 to be inserted into the first recess 303 and for the first snap-fit ​​part 202 to cooperate with the second snap-fit ​​part 302.

[0066] It should be noted that the second main body 203 and the connecting body 204 are integrally formed, or the second main body 203 and the connecting body 204 are separately manufactured and then connected and fixed into one by welding, bonding or other methods.

[0067] It should be noted that the user needs to rotate the locking part 20 during operation. In order to facilitate the user to rotate the locking part 20, anti-slip patterns are provided on the outer surface of the second body 203 to increase friction and prevent slippage.

[0068] In this embodiment of the present invention, the end face of the connector 204 facing the first recess 303 is provided with a first plane 205, and the end face of the first recess 303 facing the connector 204 is provided with a second plane 304, and the first plane 205 and the second plane 304 are provided corresponding to each other.

[0069] For example, see Figure 3 as well as Figure 4 When the locking member 20 is rotated to move the anti-loosening member 30 close to the clamping end 102 to clamp the target object, the first plane 205 and the second plane 304 abut against each other. By setting the first plane 205 and the second plane 304, the contact area between the locking member 20 and the anti-loosening member 30 is increased, thereby improving the stability of the locking member 20 in clamping the target object.

[0070] In this embodiment of the utility model, a buffer 60 is provided between the anti-loosening member 30 and the clamping end 102.

[0071] For example, the buffer 60 can be a silicone pad, a rubber pad, or a cotton pad to prevent the anti-loosening element 30 from scratching the target object during clamping, and also to prevent impact and abnormal noise between the anti-loosening element 30 and the target object.

[0072] It should be noted that the end face of the buffer 60 facing the clamping end 102 is provided with anti-slip patterns. When the buffer 60 comes into contact with the target object, the anti-slip patterns on the buffer 60 increase the friction between the buffer 60 and the target object, which is beneficial for the stable clamping of the target object by the camera device fixture.

[0073] In this embodiment of the present invention, the end of the anti-loosening member 30 facing the buffer member 60 has a second recess 305, and the buffer member 60 is disposed in the second recess 305; the first recess 303 and the second recess 305 are respectively disposed at opposite ends of the anti-loosening member 30, and the axial cross section of the anti-loosening member 30 is "H" shaped.

[0074] Since the buffer 60 is embedded inside the second recess 305, the second recess 305 increases the contact area between the buffer 60 and the anti-loosening member 30, thereby increasing the connection stability of the buffer 60; furthermore, adhesive can be applied between the buffer 60 and the second recess 305 to make the installation of the buffer 60 more secure.

[0075] In this embodiment of the utility model, the locking component 20 is a locking nut, and the anti-loosening component 30 is an anti-loosening washer.

[0076] It should be noted that the target object clamped by this utility model can be a camera, a photography light, a probe, a microphone, a flash, or other photographic equipment. The clamping end 102 is located at one end of the first body 101, and the other end of the first body 101 can be provided with a clamping opening 105. One end of the first body 101 can be clamped onto the photography light through the cooperation of the clamping end 102 and the locking member 20, and the other end of the first body 101 can clamp the flash through the clamping opening 105.

[0077] The specific usage process of this utility model is as follows: Rotate the locking member 20, and the locking member 20 will drive the anti-loosening member 30 away from the clamping end 102, forming a clamping space between the anti-loosening member 30 and the clamping end 102. According to actual needs, align the clamping space with the target object, such as a camera, photographic light, probe, microphone, flash and other photographic equipment; then the user rotates the locking member 20 in the opposite direction, and the locking member 20 will drive the anti-loosening member 30 closer to the clamping end 102 until the anti-loosening member 30 abuts against the target object.

[0078] The above provides a detailed description of a photographic equipment clamp disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the photographic equipment clamp of this utility model and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
