Description

Technical Field

[0001] The invention relates to the technical field of photographic and video equipment manufacturing, and in particular to a nested photographic tripod. Background Art

[0002] At present, the existing tripod includes a support leg, an intermediate connecting part, a middle column, a middle column lock and a bearing platform. The middle column is arranged through the intermediate connecting part and can be raised and lowered; the bearing platform is connected to the upper part of the middle column, and the middle column and the intermediate connecting part can be locked and fixed to each other through the middle column lock. The middle column can not only increase the height of the tripod, but also facilitate the photographer to adjust the height. Each support leg is composed of segmented leg tubes, and the upper and lower leg tubes can slide relative to each other and are locked and fixed to each other through the leg tube lock. When in use, first release the leg tube lock, then pull the leg tube to the required length, and then lock the leg tube lock. In addition, there is a connecting shaft between the support leg and the intermediate connecting part, so that the support leg can be opened and closed, and the support leg and the intermediate connecting part adjacent to the connecting shaft are respectively provided with matching angle positioning members, so that the support leg can be positioned at several different opening angles. For low camera positions, the support leg can be shortened to the shortest and opened to the maximum angle.

[0003] 3. The existing technology has several shortcomings:

[0004] (1) When significantly lowering the camera from a high position, it is necessary to retract the leg tubes of each support leg step by step, release the angle positioning parts of each support leg one by one, and then open the support leg to the maximum angle and put it on the ground. To return to the high position, this complex process needs to be completed in reverse order.

[0005] (2) After placing the support legs on the ground at the maximum angle, the bottom of the center column usually touches the ground first, so the center column may need to be raised, resulting in the maximum opening angle of the tripod not being effectively used to lower the camera. The minimum height can never be lower than the length of the center column.

[0006] (3) Since the supporting legs are usually still about 50-60 cm when they are shortened to the shortest, when the height is lowered by the maximum opening angle, the tripod is often difficult to arrange when the space is limited because it occupies too much area, and it also brings problems such as affecting the passage of others.

[0007] Therefore, in order to solve the above problems, the inventor provides a nested photography tripod. Summary of the invention

[0016] Among them, it also includes a secondary center column lock; the secondary center column lock is arranged on the secondary connecting part, and in the locked state, the working surface of the secondary center column lock is in close contact with the secondary center column.

DETAILED DESCRIPTION

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1-Figure 4 As shown, a nested photographic tripod provided by the present invention includes a main supporting leg 1, a main connecting part 3, a main center column 4, a secondary connecting part 5, and a secondary center column 8; the main supporting leg 1 is hinged to the main connecting part 3 to support the main connecting part 3, and the main center column 4 includes a plurality of secondary supporting legs 401, and the plurality of secondary supporting legs 401 are hinged to the secondary connecting part 5 to support the secondary connecting part 5; in the working state, the plurality of secondary supporting legs 401 are folded and inserted and fixed in the main connecting part 3, and the secondary center column 8 is inserted and fixed in the secondary connecting part 5.

[0035] In the above technical solution of the present application, the main supporting leg 1 is hinged to the main connecting part 3 to support the main connecting part 3, and the main center column 4 can be raised and lowered in the main connecting part 3 to support the secondary connecting part 5 and the secondary center column 8; the main center column 4 includes a plurality of secondary supporting legs 401, and the plurality of secondary supporting legs 401 are hinged to the secondary connecting part 5 to support the secondary connecting part 5. In this way, the main center column 4 and the top platform of the tripod are designed into a compact secondary tripod. When the main tripod (main supporting leg 1) is usually used as a support, the secondary tripod (secondary supporting leg 401) serves as the first center column, and the center column of the secondary tripod (secondary center column 8) serves as the second center column. When it is necessary to significantly lower the camera position from a high position, the first center column is directly pulled out, and the secondary supporting legs 401 are unfolded to form a secondary tripod. The height can be conveniently raised or lowered using the secondary center column 8. After use, the secondary supporting legs 401 are directly folded and installed back on the main connecting part 3. The whole switching process is convenient, time-saving, and easy to operate. In addition, the secondary supporting legs serve as the main center column on the one hand to meet the needs of high camera positions, and as a secondary tripod on the other hand to meet the needs of low camera positions. When used in low camera positions, they occupy less space than tripods of conventional sizes.

[0036] Specifically, it also includes a main center column lock 22; the main center column lock 22 is arranged on the main connecting part 3, and the main center column lock 22 is threadedly connected to the main connecting part 3. In the locked state, one end of the main center column lock 22 passes through the main connecting part 3 and abuts against the middle gasket. The middle gasket hugs the main center column 4 to fix the main center column 4 on the main connecting part 3.

[0037] Specifically, it also includes a secondary center column lock 7; the secondary center column lock 7 is arranged on the secondary connecting part 5, and the secondary center column lock 7 is threadedly connected to the secondary connecting part 5. In the locked state, one end of the secondary center column lock 7 passes through the main connecting part 3 and abuts against the secondary center column 8 to fix the secondary center column 8 on the secondary connecting part 5; preferably, as Figure 5 As shown, one end of the secondary center column lock 7 passes through the main connecting portion and abuts against the middle gasket 14 , and the middle gasket 14 hugs the secondary center column 8 .

[0038] Preferably, if Figure 5As shown, the top of the main connecting part 3 has a circular sleeve 301 extending upward, and the main center column lock includes a tapered sleeve 12 and an outer ring sleeve 13. The inner side surface of the circular sleeve is a pressure-bearing inclined surface, and the tapered sleeve is located between the circular sleeve and the outer side surface of the main center column. The outer side surface of the tapered sleeve is a pressure-applying inclined surface, and the pressure-applying inclined surface cooperates with the pressure-bearing inclined surface. The outer ring sleeve is arranged outside the circular sleeve and is threadedly engaged with the outer side surface of the circular sleeve; the top end of the outer ring sleeve and the top end of the tapered sleeve are both higher than the top end of the circular sleeve, and the top end of the outer ring sleeve has a first engaging portion inwardly, and the top end of the tapered sleeve has a second engaging portion outwardly, and the first engaging portion and the second engaging portion cooperate with each other.

[0039] Similarly, the top of the secondary connecting part has a circular sleeve extending upward, and the secondary center column lock includes a tapered sleeve and an outer ring sleeve. The inner side surface of the circular sleeve is a pressure-bearing inclined surface, and the tapered sleeve is located between the circular sleeve and the outer side surface of the secondary center column. The outer side surface of the tapered sleeve is a pressure-applying inclined surface, and the pressure-applying inclined surface cooperates with the pressure-bearing inclined surface. The outer ring sleeve is arranged outside the circular sleeve and is threadedly engaged with the outer side surface of the circular sleeve; the top end of the outer ring sleeve and the top end of the tapered sleeve are both higher than the top end of the circular sleeve, the top end of the outer ring sleeve has a first engaging portion inwardly, and the top end of the tapered sleeve has a second engaging portion outwardly, and the first engaging portion and the second engaging portion cooperate with each other. By screwing the outer ring sleeve, due to the cooperation between the first interlocking part and the second interlocking part, the outer ring sleeve drives the cone sleeve to move downward at the same time, and the pressure inclined surface of the cone sleeve presses against the pressure inclined surface of the inner side of the circular sleeve. The pressure inclined surface and the pressure inclined surface interact with each other, and the inner side of the cone sleeve hugs the outer side surface of the secondary center column, thereby locking the secondary center column on the secondary connecting part.

[0040] Preferably, the top end of the secondary supporting leg 401 is bent outward to form a bent section 11 , and the bent section 11 is hinged to the outer side of the secondary connecting portion 5 .

[0041] Preferably, the bending section 11 has a secondary connecting shaft 10, and the secondary connecting part 5 and the secondary supporting leg 401 are rotatably connected via the secondary connecting shaft 10. The secondary supporting leg 401 is bent outward in the area close to the secondary connecting part 5, and the secondary connecting shaft 10 is provided in the section bent outward, and the secondary connecting part 5 and the secondary supporting leg 401 are rotatably connected via the secondary connecting shaft 10; in this way, the connecting shaft between the secondary supporting leg 401 and the secondary connecting part 5 can have a larger size, and the secondary tripod center column can also have a larger cross-sectional size, ensuring that the connecting shaft between the secondary supporting leg 401 and the secondary connecting part 5 can also withstand a higher load, and the structure is more reliable.

[0042] Preferably, one end of the secondary center column 8 is fixedly connected to the support platform 6, a pan / tilt is arranged on the support platform 6, and the other end is inserted and fixed in the secondary connection part 5 along the axial direction of the secondary center column 8 so as to be liftable. When it is necessary to significantly lower the camera position from a high position, the first center column is directly pulled out, the secondary support legs 401 are unfolded to become a secondary tripod, and the secondary center column 8 can be used to conveniently raise and lower the height. In the present application, when fine-tuning is required, the secondary center column is adjusted in the above manner, and the main center column can be fixed at this time, and the main center column is used for large-scale height adjustment, and the adjustment of the main center column and the secondary center column does not affect each other.

[0043] Preferably, a limiting protrusion 9 is provided on the outer side of the bending starting point of the bending section 11. When the multiple secondary supporting legs 401 are folded and inserted into the main connecting part 3, the limiting protrusion 9 cooperates with the top of the main connecting part 3 to avoid unreliable cooperation of the secondary supporting legs 401 in the main connecting part 3.

[0044] Preferably, the bending section 11 has a step protruding outward, and the step cooperates with the top of the main connecting part 3 to avoid unreliable cooperation of the secondary supporting leg 401 in the main connecting part 3.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
