[0001] The present application relates to the field of photography, video and measurement, in particular to a combined tripod. BACKGROUND

[0002] The tripod is a kind of fixed and angle adjusting tool for setting up photographic camera, video camera and other instruments by connecting with the holder.

[0003] At present, the space utilization rate between the tripods is low, and it is not convenient to store. SUMMARY

[0004] The present application aims at the above-mentioned deficiencies of the prior art, and provides a combined tripod which makes full use of the space utilization rate between the tripods and is convenient to store.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] The present application provides that a child bracket and a mother bracket are combined together through a main connecting bracket. When used together, the child bracket plays the role of the central axis and adjusts the height. When separated, two independent function tripods are formed. The outer buckle lock of the mother bracket, i.e. the locking mechanism, is also innovatively designed, which is beneficial to quick deployment and storage.

[0007] The three main bracket legs can be as close to each other as possible, and the space occupation is reduced. The three central axis legs of the child bracket can be inserted into the outer gap between the three main bracket legs. The cross-sectional shape can be determined according to the gap shape, so as to form the most compact space structure.

[0008] The basic structure of the child bracket is a traditional structure, and a safety plug is designed at the end to prevent accidental falling and slipping of the child bracket.

[0009] A Y-shaped support frame is arranged between the three central axis legs. When used together, it is used to ensure the rigidity and parallelism between the three legs. When used separately, it is screwed into the top of the mother bracket to connect the holder.

[0010] The basic structure of the mother bracket is the same as that of the traditional tripod, and it has telescopic supporting legs.

[0011] The main connecting bracket drives three independent wedge-shaped pieces in the three wedge-shaped holes through the rotating ring sleeve to press and separate the outer wall of the central axis leg pipe, so as to realize the locking and release of the child bracket.

[0012] The outer buckle lock of the mother bracket realizes the quick locking and release between the main bracket legs. BRIEF DESCRIPTION OF DRAWINGS

[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0034] Please refer to Figures 1 to 4 A combined tripod comprises a sub-tripod 1 and a main tripod 2, which are combined together by a main connecting frame 3.

[0035] One end of the sub-tripod 1 is inserted into the main connecting frame 3, and the sub-tripod 1 can move back and forth along the direction of the m-axis. The other end of the sub-tripod 1 is provided with a Y-shaped support frame 4 for ensuring the rigidity and parallelism of the sub-tripod 1.

[0036] The main tripod 2 is adjusted or fixed in the unfolded angle by a screw 5, and the main tripod 2 is in the telescopic state by an outer buckle lock 6.

[0037] The three central legs 101 are evenly arranged outside the three main legs 201, and the main combination mode is as Figures 16 to 20 described.

[0038] Please refer to Figure 7 The main tripod 2 comprises three main legs 201, and each main leg 201 comprises a plurality of telescopic legs 202 which are coaxially connected and can be telescopically extended along the length direction of the main leg 201. Adjacent telescopic legs 202 are connected by an outer buckle lock 6.

[0039] The bottom end of the bottommost telescopic leg 202 is connected with a pipe pin 203, and the top end of the topmost telescopic leg 202 is movably connected with the main connecting frame 3 by the rotating member 5.

[0040] In a possible implementation, the plurality of telescopic legs 202 are five, the first telescopic leg 202a is sleeved with the second telescopic leg 202b, the second telescopic leg 202b is sleeved with the third telescopic leg 202c, the third telescopic leg 202c is sleeved with the fourth telescopic leg 202d, and the fourth telescopic leg 202d is sleeved with the fifth telescopic leg 202e.

[0041] And the second telescopic leg 202b, the third telescopic leg 202c, the fourth telescopic leg 202d and the fifth telescopic leg 202e can move back and forth along the length direction of the first telescopic leg 202a. Thus, the telescopic leg 202 can be extended or shortened.

[0042] In a possible implementation, the plurality of telescopic legs 202 are five, and the five telescopic legs 202 are respectively a first telescopic leg 202a, a second telescopic leg 202b, a third telescopic leg 202c, a fourth telescopic leg 202d, and a fifth telescopic leg 202e, the end of the fifth telescopic leg 202e away from the fourth telescopic leg 202d is sleeved with the tube foot 203, and the end of the first telescopic leg 202a away from the second telescopic leg 202b is movably connected with the main connecting frame 3 through the rotating piece 5.

[0043] Please refer to Figures 8 to 13 The outer buckle lock 6 comprises an integrated elastic outer ring 604, the integrated elastic outer ring 604 is sleeved with the end a of each telescopic leg 202, the integrated elastic outer ring 604 comprises an elastic band 605, the free end of the elastic band 605 is provided with a buckle arm 606 for being tightly fitted, and an elastic band fulcrum protrusion 6051 for fastening the telescopic leg 202, and the outer buckle lock 6 is symmetrically provided with a sliding groove hole 607 corresponding to the elastic band fulcrum protrusion 6051.

[0044] The end of the buckle arm 606 adjacent to the elastic band fulcrum protrusion 6051 is provided with a buckle front arm 606a, the buckle front arm 606a is provided with a buckle shaft hole 606b, and the end of the buckle arm 606 away from the elastic band fulcrum protrusion 6051 is provided with a buckle tail 606c.

[0045] The buckle shaft hole 606b is provided through the rotating shaft and the sliding groove hole 607.

[0046] The outer surface of the end of each telescopic leg 202 away from the outer buckle lock 6 is provided with a slip stop piece 404 for preventing the telescopic legs 202 from being separated from each other.

[0047] The function of the slip stop piece 404 is to stretch the next level telescopic leg 202 until the end of the slip stop piece 404 abuts against the end of the bushing 601, and then the buckle arm 606 is pressed or buckled, so that the bushing 601 is fastened or relaxed with the corresponding telescopic leg 402, thereby completing the extension or fixation of the telescopic leg 402.

[0048] In a possible implementation, the rotating shaft passes through the buckle shaft hole 606b and is inserted into the sliding groove hole 607, and since the sliding groove hole 607 is a waist hole, the rotating shaft can move in the sliding groove hole 607.

[0049] Since the end of the buckle front arm 606a is provided with a protrusion, when the rotating shaft rotates, the rotating shaft slides in the sliding groove hole 607, so that the protrusion of the buckle front arm 606a extrudes the elastic band fulcrum protrusion 6051, so that the elastic band 605 tightly presses the telescopic leg 202, and the integrated elastic outer ring 604 is buckled tightly with the telescopic leg, thereby maintaining the stability between the adjacent telescopic legs.

[0050] Alternatively, the elastic band 605 and the telescopic leg can be kept in a relaxed state, the integrated elastic outer ring 604 and the telescopic leg can be kept in a relaxed state, and adjacent telescopic legs can be in a sliding state.

[0051] The movement state of the latch is as follows:

[0052] Release state: Move the buckle arm 606 outward. Under the action of the lever principle, the rotating shaft moves to the stop point in the sliding slot 607. Continue to rotate the buckle arm 606, and the buckle arm 606 retracts. Under the action of the material's elasticity, the elastic band fulcrum protrusion 6051 returns to its natural state. At this time, the elastic band 605 will not exert pressure on the elastic band fulcrum protrusion 6051, and the adjacent telescopic legs can slide freely.

[0053] Locked state: When the plate buckle arm 606 is pressed down in the opposite direction, the protrusion of the plate buckle front arm 606a first connects with the elastic band fulcrum protrusion 6051. If the plate buckle arm 606 is pressed down further, it will push the rotating shaft to move to the lower fulcrum in the sliding groove 607. If the plate buckle arm 606 is pressed down further, under the action of the lever principle, the plate buckle arm 606 will push the elastic band fulcrum protrusion 6051 forward, thereby pressing the elastic band 605, achieving the compression of the bushing 601, thereby locking the adjacent telescopic leg.

[0054] Please see Figure 5 and Figure 6 The sub-frame 1 includes three central shaft legs 101, and the main connecting frame 3 is provided with three wedge-shaped holes 301, with the three central shaft legs 101 respectively corresponding to the three wedge-shaped holes 301.

[0055] A wedge-shaped piece 302 is installed inside the wedge-shaped hole 301. A ring sleeve 303 is rotatably sleeved on the outer circumference of the main connecting frame 3. The wedge-shaped piece 302 is slidably connected to the inner wall of the ring sleeve 303. By rotating the ring sleeve 303, the wedge-shaped piece 302 is pushed to move up and down. When moving downward, due to the wedge shape, the wedge-shaped piece 302 moves laterally inward, pressing the central shaft leg 101 of the sub-frame against the inner wall. 304 This locks the central axis leg 101 in place, and releases it when the direction of movement is adjusted.

[0056] Please see Figure 15 The main connecting frame 3 has three hinged ratchet wheels 305, which are connected to three rotating parts 5 via pins 501. A pawl wrench 502 is placed inside the rotating part via pins 501. A coaxial torsion spring 503 is also placed on the pin to maintain the working position of the pawl wrench. Each telescopic leg 202 has a bushing groove 208 at end a, which is inserted into the bushing protrusion 603. The bushing protrusion 603 is set on the bushing 601. The bushing 601 has symmetrical and staggered bushing slots 602 and bushing protrusions 603.

[0057] Please refer to Figure 14 , Figure 5 and Figure 2 , the Y-shaped support frame 4 is installed between the three middle shaft legs 101, and each edge of the Y-shaped support frame 4 is respectively embedded with the safety tail plug of the three middle shaft legs 101, so as to play a supporting and limiting role for the sub-frame 1; at the same time, the Y-shaped support frame 4 is provided with a butt joint thread, which is butt jointed with the mother frame 2, so as to realize that the mother frame 2 serves as an independent tripod.

[0058] When the sub-frame is separated from the mother frame, the Y-shaped support frame 4 needs to be taken out and butt jointed with the thread 306 of the main frame connecting frame 3, so as to become a cloud platform butt joint platform of the main frame, and complete the independent function of the main frame as a tripod.

[0059] The three middle shaft legs 101 can be inserted into the side gap between the three main frame legs 201, so that the three middle shaft legs 101 and the three main frame legs 201 are closely and staggered arranged. Thus, the most compact space structure is formed. Figures 16 to 20 It is an example of the cross-section design in the following figure.

[0060] The above-mentioned embodiments only express the implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
