Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a tripod that facilitates gear switching. Background Technology

[0002] Tripods are widely used as auxiliary devices to support photographic equipment. Existing tripods include a center pole, several legs, and several stop bars. The legs are spaced apart around the center pole and can rotate relative to it. The stop bars are threaded onto their corresponding legs and abut against the center pole to restrict their rotation. Existing tripods use stop bars threaded onto the legs and abutting against the center pole to lock and unlock the legs; however, because the stop bars are prone to slipping, the locking effect is unsatisfactory. Utility Model Content

[0003] The purpose of this invention is to provide a tripod that facilitates gear switching, in order to solve the problem that existing tripods use a stop bar that is threaded onto the legs and abuts against the center bar to lock the tripod to the center bar, but the stop bar is prone to slippage and the locking effect is not good.

[0004] This utility model is achieved through the following technical solution:

[0005] A tripod for easy gear switching includes a center rod and legs. The legs are rotatable relative to the center rod. The center rod has several limiting grooves spaced apart in the rotation direction of the legs. The legs are provided with limiting members, driving members, and elastic members. The elastic members abut against the legs and the limiting members to drive the limiting members to insert into the limiting grooves. The driving members can move relative to the legs to push the limiting members, causing the limiting members to move out of the limiting grooves. When the limiting members are inserted into the limiting grooves, they restrict the rotation of the legs. When the limiting members are out of the limiting grooves, the legs are unlocked.

[0006] Furthermore, the driving member and the limiting member are obliquely pushed together, and the elastic member is located on the side of the limiting member away from the limiting groove. When the limiting member is driven out of the limiting groove by the driving member, it presses against the elastic member.

[0007] Furthermore, the limiting member moves axially along the foot rod to insert into or retract from the limiting groove, and the driving member moves radially along the foot rod to push against the limiting member.

[0008] Furthermore, the limiting member has a slanted pushing part and a blocking part, the driving member has a slanted pushing arm that cooperates with the slanted pushing part, the blocking part is provided on the slanted pushing part and located on one side of the slanted pushing arm, and the blocking part is used to insert into or exit the limiting groove.

[0009] Furthermore, the foot bar has a stop surface, and the inclined push part abuts against the stop surface when the stop part exits the limiting groove.

[0010] Furthermore, the foot rod has a guide hole for accommodating the elastic element, and the end of the limiting member away from the limiting groove is inserted into the guide hole and abuts against the elastic element.

[0011] Furthermore, the limiting member is disposed inside the foot rod, and when the limiting member is inserted into the limiting groove, the side of the driving member facing away from the limiting member protrudes from the outside of the foot rod.

[0012] Furthermore, the foot rod has a socket for the driving member to be inserted into the foot rod and abut against the limiting member. The driving member has a locking block that abuts against the foot rod at the edge of the socket to prevent the driving member from disengaging from the foot rod.

[0013] Furthermore, the foot bar has a guide groove, and the locking block moves along the guide groove when the driving member moves relative to the foot bar.

[0014] The advantage of this technical solution is that by configuring several limiting grooves spaced apart in the rotation direction of the legs on the central rod, and configuring limiting members on the legs that can move into or out of the limiting grooves, the tripod that facilitates gear switching can quickly change gears while being stably locked in the target gear.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figures 1-9 As shown, the tripod that facilitates gear switching includes a center rod 1 and a foot rod 2. The foot rod 2 can rotate relative to the center rod 1. The center rod 1 has several limiting grooves 101 spaced apart in the rotation direction of the foot rod 2. The foot rod 2 is provided with a limiting member 3, a driving member 4, and an elastic member 5. The elastic member 5 abuts against the foot rod 2 and the limiting member 3 respectively to drive the limiting member 3 to insert into the limiting groove 101. The driving member 4 can move relative to the foot rod 2 to push the limiting member 3, causing the limiting member 3 to move out of the limiting groove 101. When the limiting member 3 is inserted into the limiting groove 101, it restricts the rotation of the foot rod 2. When the limiting member 3 is out of the limiting groove 101, it unlocks the foot rod 2, allowing the foot rod 2 to rotate relative to the center rod 1.

[0028] The specific steps for using this tripod, which facilitates gear switching, are as follows:

[0029] First, apply an external force to the driving member 4 to move the driving member 4 relative to the foot rod 2 and push against the limiting member 3, causing the limiting member 3 to move out of the limiting groove 101 and unlock the foot rod 2;

[0030] Next, rotate foot lever 2 to the target position;

[0031] Finally, the external force on the driving member 4 is removed, causing the limiting member 3 to disengage from the control of the driving member 4. At this time, the elastic member 5 drives the limiting member 3 to insert into the limiting groove 101 to lock the foot rod 2.

[0032] In summary, this embodiment provides a tripod that facilitates gear switching, solving the problem that existing tripods use a stop bar connected to the legs by threads that abuts against the center rod to lock the tripod to the center rod, but the stop bar is prone to slippage and the locking effect is poor. The solution is mainly achieved by configuring several limiting grooves 101 spaced apart in the rotation direction of the legs 2 on the center rod 1, and configuring limiting members 3 on the legs 2 that can move into or out of the limiting grooves 101, so that the tripod that facilitates gear switching can quickly change gears while being stably locked in the target gear.

[0033] Among them, the gear shifting finger limiter 3 is inserted into each limit groove 101 to adjust the relative position of the foot rod 2 and the center rod 1.

[0034] In this embodiment of the invention, the driving member 4 and the limiting member 3 are obliquely pushed together. The limiting member 3 moves axially along the foot rod 2 to insert into or exit the limiting groove 101, and the driving member 4 moves radially along the foot rod 2 to push against the limiting member 3. The elastic member 5 is located on the side of the limiting member 3 away from the limiting groove 101. When the limiting member 3 is driven out of the limiting groove 101 by the driving member 4, it presses against the elastic member 5, causing the elastic member 5 to compress and accumulate energy. Specifically, the elastic member 5 is a spring. The above arrangement, by configuring the driving member 4 and the limiting member 3 in an oblique pushing cooperation, causes the limiting member 3 to compress the elastic member 5 when driven out of the limiting groove 101 by the driving member 4. This allows the driving member 4, the limiting member 3, and the elastic member 5 to drive together, resulting in a compact and simple driving structure that is easy to implement.

[0035] In this embodiment of the utility model, the limiting member 3 has a slanted pushing part 301 and a blocking part 302, and the driving member 4 has a slanted pushing arm 401 that cooperates with the slanted pushing part 301. The blocking part 302 is disposed on the slanted pushing part 301 and located on one side of the slanted pushing arm 401. The blocking part 302 is used to insert into or withdraw from the limiting groove 101. By configuring the limiting member 3 to have a slanted pushing part 301 and a blocking part 302, and configuring the driving member 4 to have a slanted pushing arm 401, the slanted pushing part 301 cooperates with the slanted pushing arm 401, and the blocking part 302 is disposed on the slanted pushing part 301 and located on one side of the slanted pushing arm 401 for inserting into or withdrawing from the limiting groove 101, the slanted pushing movement of the limiting member 3 and the driving member 4 and the insertion movement of the limiting member 3 and the limiting groove 101 are coordinated with each other without interfering with each other, resulting in a compact and reasonable structure.

[0036] In this embodiment of the invention, the foot rod 2 has a guide hole 201 for accommodating the elastic element 5, and the end of the limiting member 3 away from the limiting groove 101 is inserted into the guide hole 201 and abuts against the elastic element 5. This arrangement, by configuring the guide hole 201 on the foot rod 2 to accommodate the elastic element 5 and allow one end of the limiting member 3 to be inserted, ensures stable assembly and smooth movement of the limiting member 3 and the foot rod 2.

[0037] In this embodiment of the invention, the foot bar 2 has a stop surface 202 located on one side of the guide hole 201. The inclined push part 301 abuts against the stop surface 202 when the stop part 302 exits the limiting groove 101. This arrangement, by providing the stop surface 202 on the foot bar 2 that abuts against the inclined push part 301 when the stop part 302 exits the limiting groove 101, prevents the limiting member 3 from excessively shifting downwards.

[0038] In this embodiment of the invention, the limiting member 3 is slidably connected inside the foot rod 2. When the limiting member 3 is inserted into the limiting groove 101, it drives the driving member 4 to move, causing the side of the driving member 4 opposite to the limiting member 3 to protrude from the outside of the foot rod 2. This arrangement, by placing the limiting member 3 inside the foot rod 2 and configuring the driving member 4 such that when the limiting member 3 is inserted into the limiting groove 101, the side of the driving member 4 opposite to the limiting member 3 protrudes from the outside of the foot rod 2, making it easier for the user to press the driving member 4 to unlock the foot rod 2.

[0039] In this embodiment of the invention, the foot rod 2 has an insertion hole 203 for the driving member 4 to be inserted into the foot rod 2 and abut against the limiting member 3. The driving member 4 has a locking block 402, which abuts against the foot rod 2 at the edge of the insertion hole 203 to prevent the driving member 4 from disengaging from the foot rod 2. This arrangement, by configuring the locking block 402 on the driving member 4 to abut against the foot rod 2 and prevent the driving member 4 from disengaging from the foot rod 2, ensures stable assembly and smooth movement of the driving member 4 and the foot rod 2.

[0040] In this embodiment of the invention, the foot rod 2 has a guide groove 204, and the locking block 402 moves along the guide groove 204 when the driving member 4 moves relative to the foot rod 2. This arrangement, by configuring the guide groove 204 on the foot rod 2 to slide in cooperation with the locking block 402, ensures stable assembly and smooth movement of the driving member 4 and the foot rod 2.
