Reel linkage structure and its joint sleeve

The present invention relates to a reel linkage structure and a joint sleeve thereof, and in particular, a plurality of sets of reels can be interlocked or uncoupled by the jamming or untwisting of the joint sleeve.

Generally, the roller blind structure is mostly fixed by a bracket on both sides of the roller blind, and a roller for rolling the roller blind is arranged on a bracket to control the roller blind to rise or fall, but if the window is continuous In the case of multiple fans, it is not suitable for each of the windows to be independently provided with a reel.

To this end, a manufacturer has developed a "curtain reel linkage structure" such as the Republic of China Patent Publication No. M304304, which includes at least two sets of reel caps and a fixed frame, each of which has a linkage block, each linked The blocks are each provided with a coupling member, and the coupling members of the adjacent two sets of reel caps are coupled to each other. With a set of transmissions, multiple sets of roller blinds can be operated simultaneously.

However, in the above case, when the reel needs to be individually disassembled or adjusted, the roller blind, the fixing frame and the reel cap body need to be removed, and the adjustment can be performed independently, so that it is inconvenient in assembly and construction. The creator has developed a "roller reel linkage assembly" such as the Republic of China Patent Publication No. M458907, in which the two sets of reel connectors are not coupled to each other, but the interlocking portions of the two reel connectors are joined by the connecting ring. The interlocking can be formed, and the connecting ring is pivoted on the fixing frame by the bushing. Thereby, the two reel connectors can be interlocked or not interlocked by moving the connecting ring.

However, the two reel connecting members are pivotally mounted on the fixing bracket by the connecting ring, which is easy to cause the connecting ring or/and the bushing to be easily worn and deformed due to excessive load, thereby affecting the durability of the product.

Therefore, the present creator provides a reel linkage structure for improving the durability of the reel linkage structure, comprising: a support frame for fixing to a predetermined position, the support frame having a mounting hole; and two reel connection members, all at one end a linking portion having a first engaging portion, the linking portions of the two reel connecting members are opposite to each other, and at least one of the two reel connecting members is pivotally mounted on the mounting hole of the supporting frame; and a connecting sleeve, The utility model comprises a two-clamping device, wherein the two clamping members define a space for the sleeve to be sleeved on the linking portion of the two-reel connector, and at least one of the two clamping members is provided with a second engaging portion adjacent to the a splicing space, the two clips are detachably connected to each other to be displaced to a latching position or a disengaged position, the latching position causing the second engaging portion to engage the first engaging of the reel connecting member And the untwisting position is such that the second engaging portion is disengaged from the first engaging portion of the reel connecting member.

Further, the two clips have a pivoting end and a combined end opposite to the pivoting end, and the pivoting ends of the two clips are pivotally connected to each other to swing relative to the latching position or the untwisting position.

Further, the combination end of the two clamping members are provided with a fastening portion and a coupling hole, so that when the fastening portions of the two clamping members are fastened to each other, the coupling holes of the two clamping members are aligned with each other, and a screw is provided. Combined to fix to the aforementioned cassette position.

Further, the support frame has two supporting plates opposite to each other, and the two supporting plates are provided with the foregoing mounting holes, so that one of the reel connecting members is pivotally mounted on one of the mounting holes of one of the supporting plates by one bearing, and is provided for another The reel connector is pivotally mounted on the mounting hole of the other supporting plate by another bearing, and the receiving space is defined between the two supporting plates and the receiving space is connected to the receiving space for the connecting sleeve to be installed through the mounting hole. Enter the accommodating space.

Further, the connecting sleeve is provided with two limiting edges at the nesting space, and the two limiting edges are located on opposite sides of the linking portion of the two reel connecting members.

Further, the reel connecting member comprises a telescopic rod that is displaceable, and the telescopic rod is provided with the linking portion at one end to displace the linking portion to an extended position or a retracted position.

Further, the reel connecting member further comprises an outer casing, an inner casing and an elastic member, the inner casing is fixedly mounted in the outer casing, the inner casing has a first card portion, and the telescopic rod is movably connected The inner casing has a second card portion corresponding to the first card portion, and the elastic member is disposed between the inner casing and the interlocking portion, and the bearing sleeve is sleeved on the telescopic rod.

Further, a first guiding portion is disposed in the outer casing, and the second telescopic rod is disposed on the telescopic rod to be telescopically displaced by the guiding of the first guiding portion.

This creation has the following effects:

1. The aforementioned two-reel connector of the present invention is not pivoted to the support frame by the connecting sleeve, so that the joint sleeve can be prevented from being worn and deformed due to excessive load, thereby improving the durability of the product.

2. This creation can adjust the reeling position of the aforementioned two-reel connector without disassembling the support frame to improve the convenience of product assembly.

3. The interlocking part of the reel connecting piece in the present invention is telescopic, so that the reel connecting piece can be detached from the supporting frame without disassembling the supporting frame, thereby further improving the convenience of product assembly.
