Description

Technical Field

[0001] This utility model relates to the technical field of ventilation ducts, specifically an adjustable duct installation tool. Background Technology

[0002] Ventilation ducts, or simply ducts, are metal or non-metal pipes used in ventilation and air conditioning systems for industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. There are various ways to connect ventilation ducts, including the following common methods: clamp type, plug type, strip type, flexible hose type, and flange type. Thin-walled steel flange ventilation ducts typically require spring clips for fixing during connection, and these spring clips need to be used with installation tools during installation.

[0003] Traditional spring clip installation tools used for thin-walled steel flange ventilation duct installation have a simple structure, with the clamp and handle fixed by welding. However, in actual construction, ventilation shafts are often located in areas with cast-in-place shear walls. During subsequent duct installation, the space between the duct and the wall is relatively narrow. Traditional installation tools cannot adapt to the confined installation environment because the clamp cannot be quickly adjusted. This results in spring clips being unable to be installed or requiring unconventional installation methods, such as using self-drilling screws for fixing. Such installation methods can lead to loose duct connections and potential air leakage risks. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable duct installation tool to solve the problem mentioned in the background art that the angle of the currently used clamps cannot be adjusted according to the usage environment, resulting in a small range of adaptability.

[0035] To be more specific, both the handle 1 and the sleeve 2 are made of lead alloy, and the handle 1 and the sleeve 2 are fastened together by screws.

[0036] As a further explanation of this embodiment, the dimensions of the first connector 10 are the same as those of the second connector 14.

[0037] In this embodiment, the chuck 3 is wound with a steel wire rope 5 inside, and the top of the steel wire rope 5 is connected to the bottom of the clamp 11. At the same time, the clamp 11 and the end 12 are connected by a rotating connection.

[0038] More specifically, the chuck 3 has two sets of tooth structures symmetrically arranged on both sides, and the chuck 3 has a groove in the middle for accommodating the wire rope 5.

[0039] As a further explanation of this embodiment, pulling the wire rope 5 will cause the chuck 3 to rotate synchronously.

[0040] In this embodiment, the chuck 3 and the resetter 4 are connected by a transmission connection, and the chuck 3 and the resetter 4 form a spring-loaded structure.

[0041] More specifically, each resetter 4 has a coil spring installed inside.

[0042] As a further explanation of this embodiment, the resetter 4 facilitates the quick reset of the chuck 3.

[0043] In this embodiment, the locking block 6 is slidably connected to the handle 1, and the locking block 6 is rotatably connected to the pressure rod 8; the slider 9 is slidably connected to the sleeve 2, and the slider 9, pressure rod 8, locking block 6 and spring 7 form a spring-loaded structure.

[0044] To be more specific, pressing the slider 9 will cause the pressure rod 8 to squeeze the locking block 6.

[0045] As a further explanation of this embodiment, the spring 7 is used to drive the locking block 6 and the slider 9 to quickly reset.

[0046] In this embodiment, the first groove 17 passes through one side of the first extension rod 15 and connects the two ends of the first extension rod 15.

[0047] More specifically, the first groove 17 is used to accommodate the wire rope 5 connected between the sleeve 2 and the end 12.

[0048] As a further explanation of this embodiment, the two ends of the first extension rod 15 are respectively engaged with the first connector 10 and the second connector 14 through two first slots 16.

[0049] In this embodiment, the second groove 20 passes through one side of the second extension rod 18 and connects the two ends of the first extension rod 15.

[0050] More specifically, the second groove 20 is used to accommodate the wire rope 5 connected between the sleeve 2 and the end 12.

[0051] As a further explanation of this embodiment, the two ends of the second extension rod 18 are respectively engaged with the first connector 10 and the second connector 14 through two second slots 19.

[0052] The working principle of this utility model is as follows: By pressing the slider 9 downward with a finger, the locking block 6 can be squeezed in conjunction with the pressure rod 8. While the locking block 6 slides downward, it squeezes the spring 7. At this time, the locking block 6 disengages from the chuck 3. The angle of the clamp 11 can be quickly adjusted by rotating the clamp 11. While the clamp 11 rotates, it drives the resetters 4 on both sides to rotate synchronously. The rebound force generated by the compressed helical spring in the resetter 4 ensures that the wire rope 5 always remains taut. When the clamp 11 is adjusted to a suitable angle, the slider 9 is released, so that the locking block 6 resets under the action of the spring 7 and re-engages with the chuck 3. The clamp 11 can then be fixed at the current angle. The spring clamp can then be installed with the pry plate 13.

[0053] When it is necessary to replace the first extension rod 15 with the second extension rod 18, first press down on the slider 9, which will cooperate with the pressure rod 8 to squeeze the locking block 6. As the locking block 6 slides down, it squeezes the spring 7. At this time, the locking block 6 disengages from the chuck 3. Pull the end 12 to disconnect the second connector 14 from the first groove 16. Continue to pull the end 12 to release the wire rope 5 to a sufficient length. Then release the slider 9, so that the locking block 6 resets under the action of the spring 7 and re-engages with the chuck 3. Then pull the first extension rod 15 to make the first connector 14 disengage from the first groove 16. The groove 16 disengages from the first connector 10, and the first extension rod 15 is pulled out laterally, causing the wire rope 5 to disengage from the first groove 17. Then, the wire rope 5 is inserted into the second groove 20 from the side, and the second connecting groove 19 at the bottom of the second extension rod 18 is engaged with the first connector 10. After engaging the second connecting groove 19 at the top of the second extension rod 18 with the second connector 14, the chuck 3 is released again, and the chuck 3 is wound up with the wire rope 5 under the action of the resetter 4 until the wire rope 5 is in a taut state. Then, the locking block 6 is reset to complete the fixation.
