[0039] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0040] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0041] In the related art, in the process of creating films, television dramas, advertisements and videos, a large number of lamps are often needed for lighting, and these lamps usually need to be installed and adjusted with a tripod. In order to ensure the stability of the lamps, especially in outdoor scenes such as muddy, uneven land or sandy land, the structure of the tripod used has certain operation difficulty. In these special terrains, the tripod needs additional counterweight to ensure stability, and the counterweight part needs to be carried additionally, occupying space and increasing the complexity of operation; and for rod lamps and small power fill lights and other equipment that need to be adjusted frequently, when adjusting the position of the rod lamp and the small power fill light, the tripod needs to be moved frequently, and because the tripod also has a counterweight installed, it is more laborious during the moving process, and it is also more inconvenient to level.

[0042] A photography support is provided for the embodiments of the present application to solve the problems in the related art. The photography support provided by the embodiments of the present application will be described in detail below in combination with the drawings.

[0043] In combination with Figure 1 And Figure 2As shown, in one or more embodiments, the present application provides a photography support, which comprises: a middle tube part 100 and a plurality of supporting legs 101; the length of the middle tube part 100 is adjustable, and the middle tube part 100 has a pointed structure 102; the plurality of supporting legs 101 are distributed along the circumference of the middle tube part 100, and the plurality of supporting legs 101 are respectively hinged to the middle tube part 100, so that the photography support has an unfolded state and a folded state; wherein, when the photography support is in the unfolded state, the length direction of the supporting leg 101 and the length direction of the middle tube part 100 have a first included angle.

[0044] At least one embodiment of the present application provides a photography support, which can improve the stable support of the photography support through the plurality of supporting legs 101, and the middle tube part 100 has a telescopic function to adapt to different application scenarios, for example, the depth of insertion into the ground can be adjusted by using the pointed structure 102, and after the middle tube part 100 is inserted into the ground, the additional counterweight in the related art can be omitted, which is convenient for carrying and installation. For rod lights and small-power fill lights and other devices that need to be frequently replaced, this structure is particularly convenient, thereby improving the outdoor lighting efficiency of the rod light and the small-power fill light that need to be flexibly adjusted in position.

[0045] In some embodiments, after the length of the middle tube part 100 is extended, the length of the middle tube part 100 after extension is increased, so that when the photography support is in the unfolded state, the pointed structure 102 can be inserted into the ground, so that part of the structure of the middle tube part 100 is inserted into the ground to a sufficient depth. After the length of the middle tube part 100 is shortened, the length of the middle tube part 100 after shortening can be reduced, which is convenient for the storage and carrying of the photography support when the photography support is in the folded state. The ground can be soil, sandy soil or grassland, as long as the pointed structure 102 can be inserted when the photography support is used. It can be understood that the ground can also be a cement ground or a road ground, in which case the pointed structure 102 cannot be inserted, but the plurality of supporting legs 101 can provide stable support for the photography support when the photography support is in the unfolded state. It should be noted that when the photography support is in the folded state, the photography support can also be used, as long as the photography support is inserted into the ground to a sufficient depth by using the pointed structure 102. Of course, after the photography support in the folded state is inserted into the ground, it can also be suitable for supporting light-weight objects, such as supporting fill lights that are light in weight or small in size; the pointed structure 102 can be a conical structure.

[0046] In some embodiments, the first included angle is an acute angle or a right angle, so that the height of the unfolded photography support can be adjusted to meet different application scenarios.

[0047] In combination Figure 1 and Figure 2As shown in the drawings, in some embodiments, the middle tube part 100 comprises a main tube 103 and a middle shaft tube 104, the middle shaft tube 104 is inserted into the main tube 103, and the leg 101 is hinged to the main tube 103. In this way, by inserting the middle shaft tube 104 into the main tube 103, the length of the middle shaft tube 104 extending out of the main tube 103 can be adjusted to adjust the height of the camera support in the unfolded state; the main tube 103 can also provide connection support for the leg 101. For example, a plurality of legs 101 are distributed around the circumference of the main tube 103, and the number of legs 101 can be three or four, etc.; one end of the leg 101 is hinged to one end of the main tube 103; and the middle shaft tube 104 is inserted into the main tube 103.

[0048] In combination Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the camera support further comprises a connecting rod 105, one end of the connecting rod 105 is hinged to the main tube 103, and the other end of the connecting rod 105 is hinged to the leg 101. In this way, the connecting rod 105 is used to limit the maximum unfolding angle between the leg 101 and the main tube 103. For example, the number of connecting rods 105 is equal to the number of legs 101, that is, one connecting rod 105 is connected between each leg 101 and the main tube 103.

[0049] In combination Figure 2 , Figure 3 and Figure 6 As shown in the drawings, in some embodiments, the cross section of the leg 101 is in the shape of a fan ring, and the cross section of the main tube 103 is in the shape of a circular ring; when the camera support is in the folded state, a plurality of legs 101 are wrapped on the outer circumferential surface of the main tube 103, so that the camera support in the folded state is in the shape of a cylinder, which is convenient for the storage of the camera support.

[0050] In combination Figure 2 and Figure 3 As shown in the drawings, in some embodiments, the side of the leg 101 facing the main tube 103 has a plurality of first ribs 106, and the plurality of first ribs 106 are distributed along the length direction of the leg 101. By using the first ribs 106, the strength of the leg 101 is ensured, and the service life of the camera support is improved. For example, the side of the leg 101 facing the main tube 103 also has a second rib 107, and the length direction of the second rib 107 is parallel to the length direction of the leg 101. In this way, by intersecting the first rib 106 and the second rib 107, the strength of the leg 101 is further ensured.

[0051] In combination Figure 1 , Figure 4 and Figure 5In some embodiments, the camera support further comprises a locking mechanism 117 arranged between the main tube 103 and the central tube 104 to keep the main tube 103 and the central tube 104 relatively fixed. The locking mechanism 117 is located at one end of the main tube 103. After the central tube 104 is extended to the desired length from the main tube 103, the locking mechanism 117 can be used to lock the central tube 104 and the main tube 103 to keep the central tube 104 extended to the desired length from the main tube 103. For example, the locking mechanism 117 comprises a screw nut 108 and an insertion sleeve 109. The screw nut 108 can rotate relative to the insertion sleeve 109, and the screw nut 108 and the insertion sleeve 109 are axially fixed. The insertion sleeve 109 has a guide slope 110, and the angle between the guide slope 110 and the rotation axis of the screw nut 108 is an acute angle. The screw nut 108 and the insertion sleeve 109 can be connected by a bearing, i.e., the screw nut 108 is fixedly connected with the outer ring of the bearing, and the insertion sleeve 109 is fixedly connected with the inner ring of the bearing. In this way, the screw nut 108 and the insertion sleeve 109 cannot move relative to each other in the axial direction of the main tube 103, but the screw nut 108 can rotate relative to the insertion sleeve 109 around the axis of the main tube 103. The screw nut 108 is threadedly connected with the outer surface of the main tube 103, and part of the structure of the insertion sleeve 109 can be inserted into the lumen of the main tube 103. The central tube 104 is inserted into the lumen of the main tube 103, and the insertion sleeve 109 is sleeved on the outer surface of the central tube 104. In this way, during the screwing of the screw nut 108 relative to the main tube 103, the insertion sleeve 109 can be inserted into the gap between the central tube 104 and the main tube 103 under the guidance of the guide slope 110. In this way, the insertion sleeve 109 fills the gap between the central tube 104 and the main tube 103, so that the central tube 104 and the main tube 103 can be axially fixed, thereby keeping the central tube 104 extended to the desired length from the main tube 103. When it is necessary to adjust the length of the central tube 104 extended from the main tube 103, the screw nut 108 can be rotated in the loosening direction to make the insertion sleeve 109 exit the gap between the central tube 104 and the main tube 103. It can be understood that, in order to provide a certain damping between the insertion sleeve 109 and the central tube 104, the insertion sleeve 109 and the second telescopic section 113 can be in interference fit when the locking mechanism 117 is in the unlocked state, and the central tube 104 can move relative to the insertion sleeve 109.

[0052] It should be noted that in some other possible embodiments, the locking mechanism 117 can also be a screw. The main tube 103 has a threaded through hole that mates with the screw. The end of the screw can abut against the central tube 104. In this way, when the screw is screwed into the threaded through hole and the end of the screw is in close contact with the central tube 104, the central tube 104 and the main tube 103 can be axially fixed, thereby maintaining the required length of the central tube 104 extending beyond the main tube 103.

[0053] Combination Figure 1 and Figure 2 As shown, in some embodiments, the middle tube 100 further includes a telescopic tube 111, which is inserted into the main tube 103, and a pointed structure 102 is disposed on the telescopic tube 111. By utilizing the telescopic tube 111, the length of the middle tube 100 can be extended or shortened. Exemplarily, the telescopic tube 111 is inserted into the lumen of the main tube 103.

[0054] Combination Figure 1 and Figure 2As shown, in some embodiments, the telescopic tube 111 comprises a plurality of telescopic sections which are inserted into each other, and the pointed structure 102 is located at the end of one of the telescopic sections, so that the plurality of telescopic sections are used to adjust the length of the middle tube section 100. For example, the telescopic tube 111 comprises two telescopic sections, which are a first telescopic section 112 and a second telescopic section 113, the first telescopic section 112 is inserted into the main tube 103, and the second telescopic section 113 is inserted into the first telescopic section 112; the spring plunger 114 is installed on the first telescopic section 112, and the first through hole 115 which cooperates with the spring plunger 114 is formed on the main tube 103. The telescopic section is a tubular structure; the pointed structure 102 is arranged at the end of the second telescopic section 113, and the locking mechanism 117 is arranged between the first telescopic section 112 and the second telescopic section 113, so that the first telescopic section 112 and the second telescopic section 113 can be kept relatively fixed. After the second telescopic section 113 is extended from the first telescopic section 112 by a required length, the locking mechanism 117 can be used to lock the second telescopic section 113 and the first telescopic section 112, so as to keep the second telescopic section 113 extended from the first telescopic section 112 by the required length. For example, the threaded nut 108 is threadedly connected between the outer surface of the first telescopic section 112, and the part of the insertion sleeve 109 can be inserted into the lumen of the first telescopic section 112, the second telescopic section 113 is inserted into the lumen of the first telescopic section 112, and the insertion sleeve 109 is sleeved on the outer surface of the second telescopic section 113, so that during the rotation of the threaded nut 108 relative to the first telescopic section 112, the insertion sleeve 109 can be inserted into the gap between the second telescopic section 113 and the first telescopic section 112, so that the insertion sleeve 109 is used to fill the gap between the second telescopic section 113 and the first telescopic section 112, so that the second telescopic section 113 and the first telescopic section 112 can be axially fixed, so as to keep the second telescopic section 113 extended from the first telescopic section 112 by the required length. When it is needed to adjust the length of the second telescopic section 113 extended from the first telescopic section 112, the threaded nut 108 can be rotated in the loosening direction, so that the insertion sleeve 109 exits the gap between the second telescopic section 113 and the first telescopic section 112. It can be understood that in order to make the insertion sleeve 109 and the second telescopic section 113 have a certain damping, when the locking mechanism 117 is in the unlocked state, the insertion sleeve 109 and the second telescopic section 113 can be in interference fit, and the second telescopic section 113 can move relative to the insertion sleeve 109. For the locking mechanism 117 arranged between the first telescopic section 112 and the second telescopic section 113, it can be combined with Figure 4 and Figure 5 as shown.

[0055] It should be noted that in some other possible embodiments, when the locking mechanism 117 between the first telescopic joint 112 and the second telescopic joint 113 is a screw, the first telescopic joint 112 has a threaded through hole that mates with the screw, and the end of the screw can abut against the second telescopic joint 113. Thus, when the screw is screwed into the threaded through hole and the end of the screw is in close contact with the second telescopic joint 113, the second telescopic joint 113 and the first telescopic joint 112 can be axially fixed, thereby maintaining the required length of the second telescopic joint 113 extending beyond the first telescopic joint 112. It should also be noted that in some other possible embodiments, the number of telescopic joints is not limited to two, but can also be three or four, and a locking mechanism 117 can be provided between the two interlocking telescopic joints, or a locking structure in the form of a spring plunger 114 engaging with the first through hole 115 can be provided.

[0056] Combination Figure 1 and Figure 9 As shown, in some embodiments, the main tube 103 has at least two first through holes 115, one of which is located at the opposite end of the main tube 103, while the other is located away from the opposite end of the main tube 103. When the spring plunger 114 is inserted into the first through hole 115 located at the opposite end of the main tube 103, the first telescopic joint 112 can extend out of the main tube 103 and be axially fixed between them; when the spring plunger 114 is inserted into the first through hole 115 located away from the opposite end of the main tube 103, the first telescopic joint 112 can be retracted. In some embodiments, the end of the central tube 104 has a screw 116, which is used to facilitate connection with a lamp or fill light. Exemplarily, the screw 116 may have a 1 / 4 thread.

[0057] In some embodiments, the support leg 101 can be made of metal, the central tube 104 can be made of metal, the main tube 103 can be made of metal, and the telescopic joint can be made of metal; the metal can be aluminum alloy or stainless steel. It should be noted that in some other possible embodiments, the support leg 101, central tube 104, main tube 103, and telescopic joint can also be made of carbon fiber. The insertion sleeve 109 can be made of metal or plastic.

[0058] The photography stand provided in this application embodiment can have multiple usage states, mainly three types:

[0059] The first type, see below. Figure 7As shown, when the camera stand is in the collapsed state, the whole is cylindrical, and the pointed structure 102 at the bottom can be easily inserted into the ground 200 such as soil, sand or grass, and the screw 116 at the top of the central shaft tube 104 can be connected to a lamp or an accessory; this state directly connects the bar lamp 300 or the small power light supplement lamp, which can be directly inserted into the soil and sand ground for quick lighting without the camera stand in the expanded state. It can be understood that when the weight of the lamp or accessory connected by the central shaft tube 104 is heavy, the multiple supporting legs 101 can also be expanded while the pointed structure 102 is inserted into the ground 200 to provide stable support for the camera stand.

[0060] The second, see Figure 8 As shown, when the camera stand is in the expanded state, the pointed structure 102 at the bottom can be easily inserted into the ground 200 such as soil, sand or grass, and the locking mechanism 117 between the third telescopic joint and the second telescopic joint 113 can flexibly adjust the length of the telescopic tube 111. Compared with the method of lowering the center of gravity by placing sandbags at the bottom of the tripod in the related art, the application uses the pointed structure 102 to insert into the ground 200, which has the characteristics of quickness and convenience, and does not need to carry additional counterweight, and can quickly fix the stand.

[0061] The third, see Figure 9 As shown, when the camera stand needs to be moved into the room, the pointed structure 102 may not be inserted into the ground at this time, and the telescopic tube 111 can be retracted by using the spring plunger 114 and the locking mechanism 117, so that the pointed structure 102 is away from the ground, thereby increasing the versatility of the camera stand.

[0062] The above only describes optional embodiments of the application and does not limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
