Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
As shown in fig. 1 to 6, the embodiment of the utility model discloses a telescopic lifting rod. The hoisting rod can be used for installing the hoisting lamp on a support such as a ceiling. The telescopic hoisting rod of the embodiment comprises a first sleeve 1, a second sleeve 2, a pressing sleeve 3 and a rotary sleeve 4.
As shown in fig. 1 to 3, two ends of the first sleeve 1 are a first connection end 11 and a first sliding end 12, respectively. The two ends of the second sleeve 2 are a second connecting end 21 and a second sliding end 22 respectively. The second sliding end 22 of the second sleeve 2 is inserted into the first sliding end 12 of the first sleeve 1 and can be extended and retracted relative to the first sleeve 1. The first sleeve 1 and the second sleeve 2 can be metal tubes such as copper tubes, aluminum tubes or stainless steel tubes. The first sleeve 1 and the second sleeve 2 may be round pipes, square pipes or other special pipes.
The pressing sleeve 3 and the rotating sleeve 4 are used for locking the first sleeve 1 and the second sleeve 2 into a whole. As shown in fig. 1, 4 and 5, the pressing sleeve 3 is a substantially short pipe structure. The pressure sleeve 3 is fixedly connected to the first sliding end 12 of the first bushing 1. The pressing sleeve 3 can be fixedly connected to the first sleeve 1 by means of threaded connection and the like. In the present embodiment, a second internal thread 13 is provided at the first sliding end 12 of the first sleeve 1, and a second external thread 35 matching the second internal thread 13 is provided on the pressing sleeve 3. The fixing between the pressing sleeve 3 and the first sleeve 1 can be realized through the combination of the second external thread 35 and the second internal thread 13. The pressing sleeve 3 can also be fixed to the first sleeve 1 by gluing, snapping, interference, or other known connection methods.
The press sleeve 3 has an inner bore 31 through which the second sliding end 22 of the second sleeve 2 can slide. The pressing sleeve 3 also has a conical tubular part 32 capable of embracing the second sleeve 2, the end part of the tubular part 32 is provided with two or more through grooves 33 penetrating through the inner surface and the outer surface of the tubular part 32, and the outer surface of the tubular part 32 is provided with a first external thread 34. The through groove 33 divides the end portion of the tubular portion 32 into two or more movable pieces separated from each other, the outer diameter of the end portion of the tubular portion 32 is small, and the outer diameter of the tubular portion 32 is larger as it is closer to the middle region of the sleeve 3, so that the tubular portion 32 is tapered. In the present embodiment, the pressing sleeve 3 is an elastic plastic member, when the tubular portion 32 is pressed toward the axial center, the movable piece of the tubular portion 32 approaches the axial center, and then presses the second sleeve 2. The pressing sleeve 3 may be made of a metal member having a certain elasticity such as copper, and the thickness of the tubular portion 32 is reduced to facilitate deformation. The pressing sleeve 3 may also be a metal part with elasticity, such as a copper part, or a part made of spring steel, which can deform after being stressed.
The nipple 4 is a cylindrical part having a first internal thread 41 that matches the first external thread 34 of the tubular portion 32. The rotary sleeve 4 can be screwed on the first external thread of the tubular part 32 of the second sleeve 2, so that the movable sheet of the tubular part 32 extrudes the second sleeve 2, and the purpose that the tubular part 32 tightly holds the second sleeve 2 is achieved. When the tubular part 32 clasps the second sleeve 2, the pressing sleeve 3 and the rotating sleeve 4 lock the first sleeve 1 and the second sleeve 2 together.
As can be seen from fig. 1 and 3, the second sliding end 22 of the second sleeve 2 is provided with a flange 23 located inside the first sleeve 1, the diameter of the flange 23 being larger than the diameter of the inner bore 31 of the press sleeve 3. The flange 23 prevents the second sleeve 2 from being removed from the press sleeve 3. In this embodiment, the flange 23 is screwed to the second sliding end 22 of the second sleeve 2. In use, the second sleeve 2 is first inserted through the inner hole 31 of the pressing sleeve 3, and then the flange 23 is screwed on the second sliding end 22 of the second sleeve 2. The flange 23 may also be fixed to the second sleeve 2 by fasteners such as screws.
As shown in fig. 6, in the present embodiment, the second connection end 21 of the second sleeve 2 is fixedly connected to a lamp 6, and the second connection end 21 can be connected to the lamp 6 by a conventional connection method such as a screw thread, a latch, and the like. The first connection end 11 of the first sleeve 1 can be connected to a support. The support may be a roof of a ceiling or the like. A decoration cover 5 is provided at the first connection end 11 to achieve an aesthetic connection effect between the first connection end 11 and the support. It should be noted that in other embodiments of the present invention, the first connection end 11 of the first sleeve 1 can also be fixedly connected to a lamp, the second connection end 21 of the second sleeve 2 is connected to a support, and a decorative cover is disposed at the second connection end. In the present embodiment, the first sleeve 1 and the second sleeve 2 are both vertically disposed, and in other embodiments, the first sleeve 1 and the second sleeve 2 may also be obliquely disposed to achieve a decorative effect.
When the telescopic hoisting rod of this embodiment is used, will revolve cover 4 and loosen for pressing cover 3 to loosen second sleeve pipe 2, can adjust second sleeve pipe 2 this moment for the flexible length of first sleeve pipe 1, after length adjustment finishes, the cover 4 is revolved in screwing, again with second sleeve pipe 2 and first sleeve pipe 1 fixed can.
To sum up, the utility model discloses embodiment's telescopic hoist and mount pole, user only need rotatory cover 4 soon, make second sleeve 2 flexible for first sleeve 1, can realize the lift of lamps and lanterns, convenient operation. Moreover, the lamp level does not need to be corrected again, and the operability is improved. Due to the adoption of the telescopic scheme, rigid hoisting can be realized, and the stability of the lamp can be improved. The wires of the lamp can pass through the first sleeve and the second sleeve, so that the safety and the attractiveness of the lamp are improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
