Description

Technical Field

[0001] The utility model relates to the field of photographic equipment, in particular to a fast-linked telescopic tube set. Background Art

[0002] The existing telescopic tube set is composed of multiple tubes that are connected to each other. Since several tubes can move relative to each other in the axial direction and adjacent tubes are provided with locking structures, the length of the telescopic tube set can be adjusted, which is flexible and convenient to use. The locking structure of the known tubes can only control the locking and unlocking of adjacent tubes individually, so the locking and unlocking of multiple tubes requires repeated operations, which is cumbersome. Utility Model Content

[0003] The utility model aims to provide a quick-interlocking telescopic tube set to solve the problem that the locking structure of the existing telescopic tube set can only control the locking and unlocking of adjacent tubes individually, and the locking and unlocking of multiple tubes require repeated operations, which is cumbersome to operate.

[0004] The utility model is realized by the following technical solutions:

[0005] A quick-interlocking telescopic pipe group includes a pipe fitting 1, a pipe fitting 2 and a pipe fitting 3 which are sequentially sleeved and can move relative to each other in the axial direction. The pipe fitting 2 is provided with a main locking mechanism for limiting the relative movement of the pipe fitting 2 and the pipe fitting 1, and a secondary locking mechanism for limiting the relative movement of the pipe fitting 2 and the pipe fitting 3. The main locking mechanism and the secondary locking mechanism are provided with interlocking mechanisms. When the main locking mechanism limits the relative movement of the pipe fitting 2 and the pipe fitting 1, the interlocking mechanism enables the secondary locking mechanism to limit the relative movement of the pipe fitting 2 and the pipe fitting 3.

[0006] Furthermore, the pipe fitting 2 has a main slide seat sleeved on the pipe fitting 1, and the main locking mechanism includes a pull button rotatably connected to the main slide seat and a main pressing block and a main locking block accommodated in the main slide seat, the main pressing block and the main locking block are obliquely pushed together, and when the pull button rotates relative to the main slide seat, it drives the main pressing block to move forward and backward, and the forward and backward movement of the main pressing block drives the main locking block to move left and right to tighten or release the pipe fitting 1.

[0007] Furthermore, the pipe fitting two has a secondary slide seat mounted on the pipe fitting three, and the secondary locking mechanism includes a secondary pressing block and a secondary locking block accommodated in the secondary slide seat, and the secondary locking block is obliquely pushed together with the secondary pressing block; when the main locking mechanism locks or releases the pipe fitting one, the interlocking mechanism causes the secondary pressing block to move up and down, and the secondary pressing block moves up and down to drive the secondary locking block to press against or release the pipe fitting three.

[0008] Furthermore, the interlocking mechanism includes a tensioning rope and a stopping column, one end of the tensioning rope is connected to the main slide seat and the other end is connected to the secondary pressing block, the stopping column is passed through the tensioning rope and cooperates with the pull buckle to make the secondary pressing block move up and push the secondary locking block to tighten or release the pipe three; the pull buckle drives the main locking block to move and tighten the pipe, temporarily releases the stopping column to make the secondary pressing block move up, and pushes the secondary locking block to tighten the pipe three when the secondary pressing block moves up; the pull buckle drives the main locking block to move and release the pipe, and temporarily stops on the stopping column to make the secondary pressing block move down, and pushes the secondary locking block to release the pipe three when the secondary pressing block moves down.

[0009] Furthermore, the secondary slide seat is provided with an elastic member below the secondary pressing block, and the elastic compression of the elastic member enables the secondary pressing block to have a movement tendency to move upward.

[0010] Furthermore, the secondary locking block is rotatably connected to the secondary slide seat and is at least partially disposed around the outside of the pipe member 3. When the secondary pressing block moves upward, the secondary locking block rotates toward the pipe member 3 and is pressed against the pipe member 3.

[0011] Furthermore, the pipe fitting 1 has two left and right opposite pipe bodies, and there are two main locking blocks, which are respectively arranged on the left and right sides of the main pressing block, and respectively tighten or release the two pipe bodies when the main pressing block moves forward and backward.

[0012] Furthermore, the main locking block has an embracing portion which is arranged outside the pipe.

[0013] Furthermore, a yield groove is provided on the side of the main emergency block opposite to the pull buckle, and a yield strip is provided on the side of the pull buckle opposite to the main emergency block, and when the pull buckle rotates relative to the main slide, the yield strip moves into or away from the yield groove; when the yield strip moves away from the yield groove, the pull buckle pushes the main emergency block to move the main emergency block backward, and when the main emergency block moves backward, it drives the main locking block to move and press against the pipe fitting one; when the yield strip moves into the yield groove, the pull buckle releases the main emergency block to move the main emergency block forward, and when the main emergency block moves forward, it drives the main locking block to move and release the pipe fitting one.

[0014] The advantage of this technical solution is that by arranging an interlocking mechanism on the main locking mechanism for limiting the relative movement of pipe fitting one and pipe fitting two and the secondary locking mechanism for limiting the relative movement of pipe fitting two and pipe fitting three, when the main locking mechanism limits the relative movement of pipe fitting one and pipe fitting two, the secondary locking mechanism limits the relative movement of pipe fitting two and pipe fitting three, thereby realizing synchronous locking and unlocking of multiple pipe fittings, simplifying operation and facilitating use.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example: Figure 1-13 As shown, the quick-interlocking telescopic pipe group includes a pipe fitting 1, a pipe fitting 2 and a pipe fitting 3 which are sequentially sleeved and can move relative to each other in the axial direction. The pipe fitting 2 is provided with a main locking mechanism 4 for limiting the relative movement of the pipe fitting 2 and the pipe fitting 1, and a secondary locking mechanism 5 for limiting the relative movement of the pipe fitting 2 and the pipe fitting 3. The main locking mechanism 4 and the secondary locking mechanism 5 are provided with an interlocking mechanism 6. When the main locking mechanism 4 limits the relative movement of the pipe fitting 2 and the pipe fitting 1, the interlocking mechanism 6 enables the secondary locking mechanism 5 to limit the relative movement of the pipe fitting 2 and the pipe fitting 3. The utility model provides a quick-interlocking telescopic pipe group to solve the problem that the locking structure of the existing telescopic pipe group can only control the locking and unlocking of adjacent pipe bodies individually, and the locking and unlocking of multiple pipe bodies need to be repeated, which is cumbersome to operate. The utility model mainly configures an interlocking mechanism 6 on a main locking mechanism 4 for limiting the relative movement of pipe fittings 1 1 and 2 and a secondary locking mechanism 5 for limiting the relative movement of pipe fittings 2 2 and 3, so that when the main locking mechanism 4 limits the relative movement of pipe fittings 1 1 and 2 2, the secondary locking mechanism 5 limits the relative movement of pipe fittings 2 2 and 3, thereby realizing synchronous locking and unlocking of multiple pipe fittings, simplifying the operation and facilitating use.

[0032] In the embodiment of the utility model, the pipe fitting 2 has a main slide 201 sleeved on the pipe fitting 1, and the main locking mechanism 4 includes a pull button 401 rotatably connected to the main slide 201 and a main pressing block 402 and a main locking block 403 accommodated in the main slide 201. When the pull button 401 rotates relative to the main slide 201, it drives the main pressing block 402 to move forward and backward, and the main locking block 403 cooperates with the main pressing block 402 in an oblique push, and moves left and right under the oblique push of the main pressing block 402 when the main pressing block 402 moves forward and backward to tighten or release the pipe fitting 1. Since the main locking mechanism 4 is configured as the pull button 401 rotatably connected to the main slide 201 and the main locking block 403 and the main pressing block 402 that cooperate with the pull button 401 to lock or release the pipe fitting 1, the locking and release of the pipe fitting 1 is achieved, and the structure is compact and reasonable.

[0033] In the embodiment of the utility model, the pipe fitting 2 2 has a secondary slide 202 sleeved on the pipe fitting 3 3, and the secondary locking mechanism 5 includes a secondary pressing block 501 and a secondary locking block 502 accommodated in the secondary slide 202, and the secondary locking block 502 is matched with the secondary pressing block 501 by an oblique push, and the interlocking mechanism 6 makes the secondary pressing block 501 move up and down when the main locking mechanism 4 locks or releases the pipe fitting 1 1, and the secondary pressing block 501 moves up and down to drive the secondary locking block 502 to press against or release the pipe fitting 3 3. Specifically, when the main locking mechanism 4 locks the pipe fitting 1 1, the interlocking mechanism 6 makes the secondary pressing block 501 move up to drive the secondary locking block 502 to press against the pipe fitting 3 3; when the main locking mechanism 4 releases the pipe fitting 1 1, the interlocking mechanism 6 makes the secondary pressing block 501 move down to drive the secondary locking block 502 to release the pipe fitting 3 3. Since the secondary locking mechanism 5 is configured as a secondary pressing block 501 that moves up and down when the interlocking mechanism 6 locks or releases the pipe 1 and a secondary locking block 502 that cooperates obliquely with the secondary pressing block 501 to lock or release the pipe 3 3, the locking and release of the pipe 3 3 are achieved, and the structure is compact and reasonable.

[0034] In the embodiment of the utility model, the interlocking mechanism 6 includes a tensioning rope 601 and a stopping column 602. One end of the tensioning rope 601 is connected to the main slide 201 and the other end is connected to the secondary pressing block 501. The stopping column 602 is penetrated by the tensioning rope 601 and cooperates with the pull button 401 to make the secondary pressing block 501 move up and down, push the secondary locking block 502 to tighten or release the pipe three 3. When the pull button 401 drives the main locking block 403 to move and tighten the pipe one 1, the stopping column 602 is released to make the secondary pressing block 501 move up under the drive of the tensioning rope 601. When the secondary pressing block 501 moves up, it pushes the secondary locking block 502 to tighten the pipe three 3. When the pull button 401 drives the main locking block 403 to move and release the pipe one 1, it stops on the stopping column 602 to make the secondary pressing block 501 move down. When the secondary pressing block 501 moves down, it pushes the secondary locking block 502 to release the pipe three 3. Specifically, the tension rope 601 is an elastic rope and makes the secondary pressing block 501 tend to move upward. Since the interlocking mechanism 6 is configured as the tension rope 601 connected to the main slide 201 and the secondary pressing block 501 respectively and the stop column 602 that cooperates with the pull button 401 to make the secondary pressing block 501 move up and down, when the main locking mechanism 4 restricts the movement of the pipe 1, the secondary locking mechanism 5 can restrict the movement of the pipe 3 3, thereby realizing the synchronous locking and unlocking of multiple pipes, and the structure is simple and compact.

[0035] In the embodiment of the utility model, the secondary slide 202 is provided with an elastic member 7 below the secondary pressing block 501, and the elastic member 7 is elastically compressed to make the secondary pressing block 501 have a tendency to move upward. Since the elastic member 7 is provided below the secondary slide 202 to make the secondary pressing block 501 have a tendency to move upward, when the trigger 401 releases the stop column 602, the secondary pressing block 501 can move upward quickly.

[0036] In the embodiment of the utility model, the secondary locking block 502 is rotatably connected to the secondary slide 202 and at least partially arranged around the outside of the pipe 3 3. When the secondary pressing block 501 moves upward, the secondary locking block 502 rotates toward the pipe 3 3 and presses against the pipe 3 3. Since the secondary locking block 502 adopts the above structure, the secondary locking block 502 rotates stably and has a good locking ability when the secondary pressing block 501 moves upward.

[0037] In the embodiment of the utility model, the pipe fitting 1 has two pipe bodies 101, the two pipe bodies 101 are opposite to each other and are arranged at intervals, there are two main locking blocks 403, the two main locking blocks 403 are arranged on the left and right sides of the main pressing block 402, and respectively press or release the two pipe bodies 101 when the main pressing block 402 moves forward and backward. Since the pipe fitting 2 has two pipe bodies 101, there are two main locking blocks 403, and they respectively press or release the two pipe bodies 101 when the main pressing block 402 moves forward and backward, the main locking mechanism 4 has a stable structure and a good locking effect.

[0038] In the embodiment of the utility model, the main locking block 403 has an embracing portion 404 disposed outside the pipe 1. Since the main locking block 403 has an embracing portion 404 disposed outside the pipe 1, the main locking block 403 has a good locking effect.

[0039] In the embodiment of the utility model, a yield groove 405 is provided on the side of the main pressing block 402 opposite to the pull buckle 401, and a yield strip 406 is provided on the side of the pull buckle 401 opposite to the main pressing block 402. When the pull buckle 401 rotates relative to the main slide 201, the yield strip 406 moves into or away from the yield groove 405. When the yield strip 406 moves away from the yield groove 405, the pull buckle 401 pushes the main pressing block 402 to move the main pressing block 402 backward. When the main pressing block 402 moves backward, it drives the main locking block 403 to move and press against the pipe fitting 1. When the yield strip 406 moves into the yield groove 405, the pull buckle 401 releases the main pressing block 402 to move the main pressing block 402 forward. When the main pressing block 402 moves forward, it drives the main locking block 403 to move and release the pipe fitting 1. The above structure enables the main pressing block 402 to move forward and backward when the pull button 401 rotates, thereby driving the main locking block 403 to move left and right to tighten or release the pipe 1, and the structure is simple and compact.

[0040] As described above, one or more implementation methods are provided in combination with specific contents, and the specific implementation of the utility model is not limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or some technical deductions or replacements made on the premise of the concept of the utility model should be regarded as the protection of the utility model.
