Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is also to be understood that the terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

The inventors of the present application have found that a photographing apparatus including a photographing device and a pan/tilt head is fixed using a tripod during photographing. Tripods typically include a ball head and a tripod body. The foot rest body is mechanically connected with the holder through the ball head.

The damping of the ball head can ensure that the camera device can continuously keep the posture after being placed at the horizontal position. However, the existing tripod structural design does not consider the situation of ball head abrasion after long-time use. After the bulb wearing and tearing, the clearance between bulb and the foot rest body increases, leads to the damping force between bulb and the foot rest body to descend, and the stability and the connection reliability of foot rest can descend for photography equipment can't keep the horizontality after fixing to the tripod, and tripod itself loses the meaning of using.

Therefore, the inventor of the present application has improved the tripod and the handle holder to improve the connection reliability of the tripod and prevent the damping from falling between the internal structures of the tripod after the tripod is used for a long time, so that it is difficult to maintain the imaging device mounted on the tripod in a preset posture. Specifically, this application embodiment provides a foot rest, includes: a connector for connecting with an external fitting; the holding structure is connected with the connecting piece; the holding structure is provided with an accommodating cavity for accommodating at least part of the connecting piece; and the foot rest body is connected with the holding structure, wherein a slot communicated with the accommodating cavity is formed in the holding structure, so that at least part of the holding structure can move along the radial direction of the accommodating cavity to reduce the caliber of the accommodating cavity, and the damping between the holding structure and the connecting piece is adjusted to hold the connecting piece tightly.

The embodiment of this application still provides a handle cloud platform, includes: a cloud deck section for mounting an image forming apparatus; one end of the handle is connected with the tripod head part; and the foot rest is connected with the other end of the handle.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 6, a foot stool 100 according to an embodiment of the present invention includes a connecting member 10, a clasping structure 20, and a foot stool body 30. The connector 10 is used for connection with an external fitting 2000 (see fig. 18).

The clasping structure 20 is connected with the connecting piece 10. The clasping structure 20 is provided with a receiving cavity 211 for receiving at least part of the connecting piece 10. The foot stool body 30 is connected with the clasping structure 20.

Wherein, the holding structure 20 is provided with a slot 212 communicated with the receiving cavity 211 to allow at least part of the holding structure 20 to move along the radial direction of the receiving cavity 211 so as to reduce the caliber of the receiving cavity 211, and further adjust the damping between the holding structure 20 and the connecting element 10 to hold the connecting element 10.

The external fitting 2000 may include a pan/tilt head with a handle, a pan/tilt head without a handle, and the like, without limitation. The image forming apparatus may be mounted on an external fitting 2000, and the external fitting 2000 is connected to the connector 10. The imaging device may include a camera, a camcorder, a cell phone, and the like. It can be understood that the foot rest 100 according to the embodiment of the present application can ensure that the imaging device mounted on the external fitting 2000 can continuously maintain the preset posture after being placed in the preset posture. Illustratively, the preset gestures include horizontal gestures.

The slot 212 of the holding structure 20 of the foot stool 100 of the above embodiment provides a guarantee for changing the caliber of the receiving cavity 211. After the foot rest 100 is used for a long time, if the damping of the connecting piece 10 and the holding structure 20 descends to cause that an imaging device on the foot rest 100 is difficult to keep a preset posture, the radial movement of at least part of the holding structure 20 along the accommodating cavity 211 can reduce the caliber of the accommodating cavity 211, so as to adjust the damping size between the holding structure 20 and the connecting piece 10, so that the holding structure 20 holds the connecting piece 10 tightly, so that the imaging device carried on an external accessory 2000 can be reliably kept in the preset posture, the connection reliability between the holding structure 20 and the connecting piece 10 is improved, and meanwhile, the stability of the foot rest 100 is also improved, and the service life of the foot rest 100 is prolonged.

In some embodiments, the slot 212 extends in a direction parallel to the axial direction of the receiving cavity 211. It will be understood that the angle between the extending direction of the slot 212 and the axial direction of the receiving cavity 211 is within the range of 0 °, 5 °, 10 ° and any other suitable angle between 0 ° and 10 °.

Illustratively, the direction of extension of slot 212 is shown as the m-direction in fig. 6. The axial direction of the accommodation chamber 211 is shown as the n direction in fig. 6.

It will be appreciated that the number of slots 212 may be designed according to practical requirements, such as one, two, three or more. In some embodiments, the number of the slots 212 is at least two, and at least two slots 212 are spaced along the circumference of the clasping structure 20 to ensure the deformability of at least part of the clasping structure 20, so as to effectively reduce the caliber of the receiving cavity 211. Illustratively, at least two slots 212 are arranged at equal intervals along the circumferential direction of the clasping structure 20, so that the caliber of the accommodating cavity 211 can be uniformly reduced, and thus, the clasping force from the clasping structure 20 received by the connecting piece 10 at different circumferential positions is more uniform, so that the clasping structure 20 can clasp the connecting piece 10 reliably.

Referring to fig. 2, in some embodiments, the connecting member 10 includes a first connecting portion 11 and a second connecting portion 12. The first connection portion 11 is used for connection with the external fitting 2000. The second connecting portion 12 is connected to the first connecting portion 11, the second connecting portion 12 is accommodated in the accommodating cavity 211, and at least a portion of the clasping structure 20 can move along the radial direction of the accommodating cavity 211 to clasp the second connecting portion 12.

In some embodiments, the first connection portion 11 is screwed with the external fitting 2000, that is, the screw thread of the first connection portion 11 is screwed with the screw thread of the external fitting 2000, so as to realize the fixed connection of the first connection portion 11 and the external fitting 2000. In other embodiments, the first connection portion 11 may also be fixedly connected to the external fitting 2000 by a snap structure, an adhesive structure, a quick release structure, or the like.

Referring to fig. 3 and 4, at least a portion of the second connecting portion 12 is accommodated in the accommodating cavity 211. The cavity wall of the receiving cavity 211 can hold the second connecting part 12 tightly, so that the connecting part 10 is reliably fixed on the stand body 30.

In some embodiments, the second connection portion 12 is a spherical structure. In other embodiments, the second connection portion 12 may also be an aspheric structure, which is not limited herein.

Referring to fig. 2-4, in some embodiments, the clasping structure 20 includes a first clasp 22 and a second clasp 23. The first clasping member 22 is connected to the attachment member 10. The second clasping member 23 is connected with the stand body 30. The second clasping member 23 is detachably connected to the first clasping member 22. Slot 212 and receiving cavity 211 are both provided on one of first clasp 22 and second clasp 23. That is, slot 212 and receiving cavity 211 are both disposed on first clasp 22; alternatively, slot 212 and receiving cavity 211 are both provided on second clasp 23.

Referring to fig. 2 to 4 and 7, in some embodiments, the first clasping member 22 is in threaded connection with the second clasping member 23, so that when the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the aperture of the accommodating cavity 211 can be reduced.

In some embodiments, when it is desired to reduce the bore of the receiving cavity 211, the first clasp 22 can be moved relative to the second clasp 23 in a threading direction. In other embodiments, when it is desired to reduce the diameter of the receiving cavity 211, the second clasp 23 can be moved relative to the first clasp 22 in a threading direction. In other embodiments, when the aperture of the receiving cavity 211 needs to be reduced, the first clasping member 22 can be moved in the screwing direction relative to the second clasping member 23, and the second clasping member 23 can be moved in the screwing direction relative to the first clasping member 22.

Referring to fig. 6 and 7, in some embodiments, one of the first clasping member 22 and the second clasping member 23 includes a threaded base portion 241, a threaded body 242 connected to the threaded base portion 241, and an external thread 243 disposed on an outer wall of the threaded body 242, and the slot 212 and at least a portion of the receiving cavity 211 are disposed on the threaded body 242. The other of the first clasping member 22 and the second clasping member 23 is provided with a threaded hole 251 and an internal thread 252 arranged on the hole wall of the threaded hole 251, and the external thread 243 is matched with the internal thread 252.

It will be appreciated that the threaded bore 251 includes an initial mounting portion and an adjustment portion. When the foot stool 100 is finished or initially used, the external threads 243 on the threaded body 242 are engaged with the internal threads 252 on the initial mounting portion to enable the first clasping member 22 to clasp the attachment member 10. When the damping between the first clasping member 22 and the connecting member 10 is reduced and is not enough to clasp the connecting member 10 after the foot stool 100 is used for a long time, the first clasping member 22 and/or the second clasping member 23 can be moved towards the thread screwing direction, so that the external thread 243 on the thread body 242 can be screwed with at least part of the internal thread 252 of the adjusting part to reduce the caliber of the accommodating cavity 211, and further the cavity wall of the accommodating cavity 211 can clasp the connecting member 10 reliably.

In some embodiments, the thread diameter of the external threads 243 is greater than the thread diameter of the internal threads 252. Illustratively, the thread diameter of the external threads 243 is slightly larger than the thread diameter of the internal threads 252 when the first clasp 22 is not connected to the second clasp 23. As can be appreciated, since the thread diameter of the external thread 243 is slightly larger than that of the internal thread 252, when the external thread 243 is screwed with the internal thread 252 to connect the first clasping member 22 and the second clasping member 23, the internal thread 252 presses the external thread 243, so that the aperture of the accommodating cavity 211 on the threaded body 242 is reduced.

Referring to fig. 6 and 7, in some embodiments, the threaded base 241 has a first opening 244 communicating with the receiving cavity 211. The threaded hole 251 has a second opening 253 through which the threaded base portion 241 is inserted to enter the interior of the threaded hole 251. The slot 212 communicates with the first opening 244. When the external thread 243 is pressed by the internal thread 252, the caliber of the first opening 244 becomes smaller.

Referring to fig. 3 and 4, in some embodiments, when the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the first clasping member 22 can reduce the diameter of the receiving cavity 211 under the radial pressing action of the second clasping member 23. Specifically, slot 212 and receiving cavity 211 are both disposed on first clasp 22. When the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the second clasping member 23 can apply a radial pressing force to the first clasping member 22. The first clasping member 22 reduces the caliber of the accommodating cavity 211 under the radial pressing action of the second clasping member 23, so that the cavity wall of the accommodating cavity 211 clasps the second connecting portion 12 of the connecting member 10.

It will be appreciated that when the first clasp 22 and/or the second clasp 23 are moved in the thread tightening direction, the second clasp 23 will exert a force on the first clasp 22. The radial pressing force includes a case where the direction of the acting force is parallel to the radial pressing force, and a case where the resolution of the acting force in the radial direction is not zero.

In some embodiments, the radial dimension of the threaded base portion 241 is larger than the radial dimension of the threaded body 242, such that the threaded base portion 241 is exposed outside the threaded hole 251 to facilitate the user to operate the threaded base portion 241, so that the first clasping member 22 moves relative to the second clasping member 23 in the screwing direction to reduce the diameter of the receiving cavity 211.

In some embodiments, external threads 243, slot 212, and receiving cavity 211 are provided on first clasp 22, internal threads 252 are provided on second clasp 23, and second clasp 23 is positioned about the exterior of first clasp 22. When the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the external thread 243 of the first clasping member 22 can enable the cavity wall of the accommodating cavity 211 to move towards the middle part close to the accommodating cavity 211 under the squeezing action of the internal thread 252 of the second clasping member 23, so that the caliber of the accommodating cavity 211 is reduced.

Referring to fig. 8, in some embodiments, the threaded body 242 has a straight cylindrical section, the threaded hole 251 has an inverted conical hole section, and the external thread 243 of the straight cylindrical section is screwed with the internal thread 252 of the inverted conical hole section to reduce the aperture of the receiving cavity 211. Illustratively, the bore diameter of the end of the inverted cone bore section near the second opening 253 is larger than the bore diameter of the end far from the second opening 253. The outer diameters of all the positions of the straight cylinder sections are the same.

When the first clasping member 22 and/or the second clasping member 23 move towards the thread tightening direction, the straight cylindrical section of the thread body 242 and the inverted taper hole section of the thread hole 251 are designed to enable the first clasping member 22 to reliably clasp the connecting member 10 under the action of the second clasping member 23, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

Referring to fig. 9, in some embodiments, the threaded body 242 has a reverse tapered section, the threaded hole 251 has a straight hole section, and the external thread 243 of the reverse tapered section is screwed with the internal thread 252 of the straight hole section to reduce the aperture of the receiving cavity 211. Illustratively, the outer diameter of the end of the reverse tapered section proximal to the first opening 244 is smaller than the outer diameter of the end distal to the first opening 244. The aperture of each part of the straight hole section is the same.

When the first clasping member 22 and/or the second clasping member 23 move towards the screwing direction, the reverse taper section of the thread body 242 and the straight hole section of the thread hole 251 are designed to ensure that the first clasping member 22 can reliably clasp the connecting member 10 under the action of the second clasping member 23, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

In some embodiments, one of the threaded body 242 and the threaded hole 251 has a tapered section, and the other of the threaded body 242 and the threaded hole 251 has a reverse tapered section, and the thread of the tapered section is screwed with the thread of the reverse tapered section to reduce the aperture of the receiving cavity 211.

Referring to fig. 10, in some embodiments, the threaded body 242 has a tapered section and the threaded hole 251 has an inverted tapered section. The tapered section of the threaded body 242 has a larger outer diameter proximate the first opening 244 than distal the first opening 244. The reverse tapered section of the threaded hole 251 has a larger inner diameter near the second opening 253 than an inner diameter far from the second opening 253. The external thread 243 at the tapered section of the threaded body 242 is screwed with the internal thread 252 at the inverted tapered section of the threaded hole 251 to reduce the diameter of the receiving cavity 211.

When the first clasping member 22 and/or the second clasping member 23 move towards the thread tightening direction, the design of the tapered section of the thread body 242 and the inverted taper hole section of the thread hole 251 can ensure that the first clasping member 22 can reliably clasp the connecting member 10 under the action of the second clasping member 23, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

Referring to fig. 11, in some embodiments, the threaded body 242 has an inverted conical section, and the threaded hole 251 has a conical section. The reverse tapered section of the threaded body 242 has an outer diameter proximate the first opening 244 that is smaller than an outer diameter distal the first opening 244. The tapered section of the threaded bore 251 has a smaller inner diameter proximate the second opening 253 than distal the second opening 253. The external thread 243 at the inverted conical section of the threaded body 242 is screwed with the internal thread 252 at the conical section of the threaded hole 251 to reduce the diameter of the receiving cavity 211.

When the first clasping member 22 and/or the second clasping member 23 move towards the screwing direction, the reverse taper section of the thread body 242 and the taper hole section of the thread hole 251 are designed to ensure that the first clasping member 22 can reliably clasp the connecting member 10 under the action of the second clasping member 23, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

Referring to fig. 12 to 16, in some embodiments, when the first clasping member 22 and/or the second clasping member 23 move in the screwing direction, the second clasping member 23 can reduce the diameter of the accommodating cavity 211 under the radial pressing action of the first clasping member 22. Specifically, slot 212 and receiving cavity 211 are both disposed on second clasp 23. When the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the first clasping member 22 can apply a radial pressing force to the second clasping member 23. The second clasping member 23 reduces the caliber of the accommodating cavity 211 under the radial pressing action of the first clasping member 22, so that the cavity wall of the accommodating cavity 211 clasps the second connecting portion 12 of the connecting member 10.

It will be appreciated that as the damping of second clasp 23 with link 10 decreases, first clasp 22 and/or second clasp 23 may be moved in a thread tightening direction such that first clasp 22 applies a force to second clasp 23, thereby causing second clasp 23 to clasp link 10. The radial pressing force includes a case where the direction of the acting force is parallel to the radial pressing force, and a case where the resolution of the acting force in the radial direction is not zero.

In some embodiments, internal threads 252 are provided on first clasp 22, external threads 243, slot 212, and receiving cavity 211 are provided on second clasp 23, and first clasp 22 is positioned about the exterior of second clasp 23. When the first clasping member 22 and/or the second clasping member 23 move in the thread tightening direction, the external thread 243 of the second clasping member 23 can move the cavity wall of the accommodating cavity 211 to the middle part close to the accommodating cavity 211 under the squeezing action of the internal thread 252 of the first clasping member 22, so that the aperture of the accommodating cavity 211 is reduced.

Referring to fig. 12, in some embodiments, the threaded body 242 has a tapered section, the threaded hole 251 has a straight hole section, and the external thread 243 of the tapered section is screwed with the internal thread 252 of the straight hole section to reduce the aperture of the receiving cavity 211. Illustratively, the tapered section of the threaded body 242 has an outer diameter proximal to the first opening 244 that is smaller than an outer diameter distal to the first opening 244. The aperture of each part of the straight hole section is the same.

When the first clasping member 22 and/or the second clasping member 23 move towards the thread tightening direction, the design of the tapered section of the thread body 242 and the straight hole section of the thread hole 251 can ensure that the second clasping member 23 can reliably clasp the connecting member 10 under the action of the first clasping member 22, so that the imaging device carried on the external fitting 2000 can be kept in the preset posture.

Referring to fig. 13, in some embodiments, the threaded body 242 has a straight cylindrical section, the threaded hole 251 has a tapered hole section, and the external thread 243 of the straight cylindrical section is screwed with the internal thread 252 of the tapered hole section to reduce the aperture of the receiving cavity 211. Illustratively, the outer diameter is the same throughout the straight barrel section of the threaded body 242. The tapered bore section of the threaded bore 251 has a larger diameter proximate the second opening 253 than distal the second opening 253.

When the first clasping member 22 and/or the second clasping member 23 move towards the thread tightening direction, the straight cylindrical section of the thread body 242 and the tapered hole section of the thread hole 251 are designed to enable the second clasping member 23 to reliably clasp the connecting member 10 under the action of the first clasping member 22, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

Referring to fig. 14 to 16, in some embodiments, one of the threaded body 242 and the threaded hole 251 has a tapered section, and the other of the threaded body 242 and the threaded hole 251 has a reverse tapered section, and the thread of the tapered section is screwed with the thread of the reverse tapered section to reduce the diameter of the receiving cavity 211.

Referring to fig. 14, in some embodiments, the threaded body 242 has a tapered section and the threaded hole 251 has an inverted tapered section. The tapered section of the threaded body 242 has an outer diameter proximal to the first opening 244 that is smaller than an outer diameter distal to the first opening 244. The inner diameter of the reverse tapered section of the threaded hole 251 near the second opening 253 is smaller than the inner diameter far from the second opening 253. The external thread 243 at the tapered section of the threaded body 242 is screwed with the internal thread 252 at the inverted tapered section of the threaded hole 251 to reduce the diameter of the receiving cavity 211.

When the first clasping member 22 and/or the second clasping member 23 move towards the thread tightening direction, the tapered section of the thread body 242 and the inverted taper hole section of the thread hole 251 are designed to enable the second clasping member 23 to reliably clasp the connecting member 10 under the action of the first clasping member 22, so that the imaging device mounted on the external fitting 2000 can be maintained in the preset posture.

Referring to fig. 15, in some embodiments, the threaded body 242 has an inverted conical section, and the threaded hole 251 has a conical section. The reverse tapered section of the threaded body 242 has an outer diameter proximate the first opening 244 that is smaller than an outer diameter distal the first opening 244. The tapered section of the threaded bore 251 has a smaller inner diameter proximate the second opening 253 than distal the second opening 253. The external thread 243 at the inverted conical section of the threaded body 242 is screwed with the internal thread 252 at the conical section of the threaded hole 251 to reduce the diameter of the receiving cavity 211.

When the first clasping member 22 and/or the second clasping member 23 move towards the screwing direction, the reverse taper section of the thread body 242 and the taper hole section of the thread hole 251 are designed to enable the second clasping member 23 to reliably clasp the connecting member 10 under the action of the first clasping member 22, so that the imaging device mounted on the external fitting 2000 can be kept in the preset posture.

In other embodiments, the threaded body 242 and the threaded hole 251 can be any other suitable shape. For example, the threaded body 242 has a cylindrical section, the threaded hole 251 has a straight hole section, and the external thread 243 of the cylindrical section is screwed with the internal thread 252 of the straight hole section to reduce the aperture of the receiving cavity 211. For another example, referring to fig. 16 and 17, the threaded body 242 is provided with an inverted conical section, and the threaded hole 251 is provided with an inverted conical section. The external thread 243 at the reverse tapered section of the threaded body 242 is screwed with the internal thread 252 at the reverse tapered section of the threaded hole 251 to reduce the diameter of the receiving cavity 211.
