Description

Technical Field

[0001] The utility model relates to the technical field of tripod accessories, in particular to a tripod opening auxiliary device. Background Art

[0002] A tripod is a tool that people need to use when working outdoors. Generally, tripods are used to fix products such as cameras, levels, theodolites, and total stations. In the art field, it can be used for outdoor sketching (painting) and can also be extended to other structures that need to be supported, which is very convenient and is an important additional hardware.

[0003] Existing expandable / retractable tripods include a central shaft rod, several legs, a shaft sleeve, and several connecting rods. The several legs are hinged on the central shaft rod and are spaced circumferentially around the central shaft rod. The shaft sleeve can move axially along the central shaft rod. The several legs and the shaft sleeve are connected by several connecting rods. The two ends of the several connecting rods are respectively hinged on the shaft sleeve and the corresponding legs. When the shaft sleeve moves along the central shaft rod, it can drive the connecting rods to rotate to synchronously retract or expand the several legs. However, the above structure is relatively complex and the production cost is relatively high. Even in the retracted state, the occupied space of the tripod is still relatively large. In addition, the retraction and expansion of the above tripod are realized by the sliding of the shaft sleeve on the central shaft rod. When used outdoors, if the shaft sleeve or the central shaft rod rusts or there are other contaminants, it is easy to cause the retraction and expansion to be not smooth.

If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0037] Specific implementation plan: see Figures 1-11 The utility model is a tripod opening auxiliary device, the tripod 6 comprises a rotating seat 61, and three long rods 62 respectively connected to the rotating seat 61, the opening auxiliary device comprises:

[0038] The triangular middle piece 1 is provided with three mutually spaced transition grooves 11 along its circumference;

[0039] One end of the extension piece is transferred into the transfer slot 11 , and a slot hole 31 is provided at one end of the extension piece away from the triangular middle piece 1 , and an opening 311 for the long rod 62 to be inserted into is provided on one side of the slot hole 31 .

[0040] As a preferred implementation of this embodiment, a rotation limiting structure is provided between the extension piece and the adapter groove 11 .

[0041] See also Figures 1-4 It can be seen that in this embodiment, the notch of the adapter groove 11 is arranged on the lower side and the outer side of the triangular middle piece 1, and the rotation limiting structure is a retaining wall 12 arranged at the upper end of the rotation groove.

[0042] Then, since it is necessary to ensure that the overall contour of the tripod 6 when it is expanded is a regular triangular pyramid so as to have very strong placement stability and aesthetics, in this embodiment, the three adapter grooves 11 are evenly spaced along the circumference of the triangular middle piece 1.

[0043] See also Figure 5 It can be seen that in this embodiment, the extension piece includes an adapter plate 2 and a connector 3, wherein one end of the connector 3 is provided with a plug-in slot 32, and the other end is provided with a slot hole 31, one end of the adapter plate 2 extends into and is fixed in the plug-in slot 32, and the other end is transferred in the adapter slot 11.

[0044] Here, the extension piece is configured to be assembled with the adapter plate 2 and the connector 3. On the one hand, it is convenient to open the mold of the connector 3. On the other hand, when the length of the extension piece needs to be adjusted, it is only necessary to replace the adapter plate 2 with different length specifications.

[0045] In addition, the material of the adapter plate 2 is generally metal. The adapter plate 2 made of metal has better hardness and folding resistance, and has a good texture. After installation, it can better support the long rod 62 and has a higher structural strength.

[0046] In addition, in this embodiment, the notch of the adapter groove 11 is set on the lower side and outer side of the triangular middle piece 1, and one end of the adapter plate 2 is connected to the adapter groove 11. When the adapter plate 2 rotates to the horizontal, the upper end of the adapter plate 2 will abut against the retaining wall 12 to form a rotation limit. At this time, the adapter plate 2 cannot continue to rotate upward and can only rotate downward.

[0047] See also Figure 1 and Figure 2 It can be seen that in this embodiment, the connector 3 has a flat state. In the flat state, the slot hole 31 extends obliquely in the up-down direction and passes through the connector 3.

[0048] Furthermore, in this embodiment, in the flat state, the opening 311 is disposed at the side of the card slot hole 31 .

[0049] Here, the slot hole 31 is arranged to extend obliquely in the upper and lower directions, and the extending direction of the slot hole 31 is substantially consistent with the extending direction of the long rod 62. Figure 7 and Figure 8 , the long rod 62 is inserted into the slot hole 31 through the opening 311, and when the three long rods 62 are successfully inserted into the slot hole 31, the assembly of the opening auxiliary device is completed. At this time, according to the position of the opening auxiliary device, the adapter plate 2 is pulled horizontally or slightly rotated downward.

[0050] After the auxiliary device for opening is assembled, the tripod 6 can be opened smoothly and placed on the ground stably. At this time, since the three long rods 62 are supported by the corresponding connectors 3 and adapters 2, and the stress points are concentrated on the triangular middle piece 1, the overall structure can be very stable.

[0051] In this embodiment, the expansion auxiliary device is suitable for installation on a tripod 6 without a central axis rod. The rotating seat 61 of the above-mentioned tripod is arranged above the long rod 62. It involves few parts and low cost. In the folded state, it occupies little space and can be more convenient to carry outside.

[0052] Next, see Figure 6 It can be seen that in order to make the adapter plate 2 rotate more stably in the adapter groove 11, in this embodiment, a plurality of protrusions 14 are respectively provided on both sides of the adapter groove 11, and the two sides of the adapter plate 2 are respectively abutted against the protrusions 14.

[0053] More preferably, a second through hole 21 and a third through hole 22 are respectively provided at both ends of the adapter plate 2, a first through hole 13 is provided on the triangular middle piece 1, a first rivet 4 is passed between the first through hole 13 and the second through hole 21, a fourth through hole 33 is provided on the connecting head 3, and a second rivet 5 is provided between the third through hole 22 and the fourth through hole 33.

[0054] Here, the first rivet 4 is equivalent to the rotating shaft for the adapter plate 2 to rotate, and the adapter plate 2 rotates around the first rivet 4. In addition, regarding the assembly between the adapter plate 2 and the connector 3, one end of the adapter plate 2 is inserted into the insertion groove 32, so that the third through hole 22 and the fourth through hole 33 are aligned, and the second rivet 5 is driven, and the assembly is completed.

[0055] See also Figures 8-10 In this embodiment, the tripod 6 is mainly an easel, and a drawing board needs to be placed on the tripod 6, so it needs to be equipped with accessories for supporting the drawing board.

[0056] In this embodiment, the above-mentioned accessories include an upper pressing piece 7 and a lower supporting piece 8, wherein the upper pressing piece 7 is provided with a first sliding hole 71 and a first positioning hole 72 which are interconnected, and the first sliding hole 71 and the first positioning hole 72 are bounded by a first clamping block 73; the lower supporting piece 8 is provided with a second sliding hole 81 and a second positioning hole 82 which are interconnected, and the second sliding hole 81 and the second positioning hole 82 are bounded by a second clamping block 83.

[0057] When the upper pressing piece 7 and the lower supporting piece 8 need to be installed on the long rod 62, the upper pressing piece 7 is located above the lower supporting piece 8. The upper pressing piece 7 and the lower supporting piece 8 both have a sliding connection state and a fixed state. In the sliding connection state, the upper pressing piece 7 is slidably connected to the long rod 62 through the first sliding connection hole 71, and the lower supporting piece 8 is slidably connected to the long rod 62 through the second sliding connection hole 81. After the upper pressing piece 7 is adjusted to a suitable height, the upper pressing piece 7 is turned upward by hand. At this time, the long rod 62 passes through the first clamping block 73 (because the upper pressing piece 7 is a plastic part, it may be slightly deformed) and enters the first positioning hole 72. The first clamping block 73 cooperates with the inner wall of the first positioning hole 72 to clamp the long rod 62 together, and the position of the upper pressing piece 7 can be fixed.

[0058] Similarly, when the lower support member 8 is adjusted to a suitable height, the upper pressure member 7 is flipped downward by hand. At this time, the long rod 62 passes through the second clamping block 83 (since the lower support member 8 is a plastic member, slight deformation may occur) and enters the second positioning hole 82. The second clamping block 83 cooperates with the inner wall of the second positioning hole 82 to clamp the long rod 62, thereby fixing the position of the lower support member 8.

[0059] Note that when fixing the drawing board, you can first fix the position of the lower supporting member 8, place the drawing board on top of the lower supporting member 8, and then fix the position of the upper pressing member 7 to complete the fixing of the drawing board.

[0060] In addition, it is generally necessary to respectively set an upper pressing member 7 and a lower supporting member 8 on the two long rods 62. The two long rods 62 together form a plane, and the drawing board can be placed on the plane. The two lower supporting members 8 jointly support the drawing board, and the two upper pressing members 7 jointly press the drawing board.

[0061] The above description of a tripod expansion auxiliary device of the utility model is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
