Description

Technical Field

[0001] This utility model belongs to the field of building tools technology, specifically relating to a ventilation pipe inspection port support device. Background Technology

[0002] When installing ventilation duct access panels, because the aluminum plate walls of the access panels are relatively thin, they are often deformed by external forces during construction. Therefore, vertical support is required for the access panels of the exhaust pipe to ensure that the access panels are not deformed or damaged.

[0003] During construction, workers used materials such as timber and formwork to build simple support devices for the openings. These devices were of fixed size and could only support a single opening, making them not very versatile. They also consumed more manpower and did not provide ideal support. Utility Model Content

[0035] Example 1

[0036] This embodiment provides, for example Figures 1-3 The ventilation duct access support device shown includes two opposing abutment plates 1, and a support component 2 is fixedly disposed between the two abutment plates 1; the two abutment plates 1 serve as the outer end faces of the support device and abut against the upper and lower ends of the ventilation duct access port, and the support component 2 serves as the support of the device and a height adjustment component, and is hinged between the two abutment plates 1.

[0037] A limit locking component 3 is welded and installed on the support component 2. The limit locking component 3 serves as the fixing and locking structure of the entire support device. By locking the support component 2, it ensures that the two abutment plates 1 will not retract due to force.

[0038] A pair of parallel slide rails 5 are fixedly provided on the inner end face of the abutment plate 1, and the slide rails 5 are arranged along the length direction of the abutment plate 1.

[0039] A height adjustment component 4 is fixedly installed on the anti-clamping plate 1; both the slide rail 5 and the anti-clamping plate 1 serve as the mounting structure for the height adjustment component 4. The installation direction of the slide rail 5 is the same as the movement direction of the height adjustment component 4, and the height adjustment component 4 is used to control the opening degree of the support device.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the height adjustment component 4 includes a sliding hinge block 41 and a fixed hinge block 42, specifically a total of four sliding hinge blocks 41 and four fixed hinge blocks 42.

[0041] Four fixed hinge blocks 42 are welded to the abutment plate 1 and located on the right side of the slide rail 5, while four sliding hinge blocks 41 are installed on the slide rail 5 and can slide on the slide rail 5.

[0042] Meanwhile, limit blocks 43 are installed at both the front and rear ends of the slide rail 5 to further limit the slide rail 5 and prevent the sliding hinge block 41 from sliding off the slide rail 5.

[0043] Furthermore, such as Figure 1 As shown, the support assembly 2 includes two sets of scissor arms 21 arranged one in front of the other. Each set of scissor arms 21 consists of an inner support rod 211 and an outer support rod 212.

[0044] The inner support rod 211 and the outer support rod 212 are installed crosswise via a pivot 22. A pivot 22 is installed through the center of the scissor rod 21 at the scissor position of the inner support rod 211 and the outer support rod 212. The inner support rod 211 and the outer support rod 212 rotate around the pivot 22.

[0045] In terms of installation position, the inner support rods 211 are all located at the inner end of the outer support rods 212.

[0046] Furthermore, the upper end of the inner support rod 211 is hinged to the abutment plate 1 via a fixed hinge block 42, while the lower end of the inner support rod 211 is hinged to the abutment plate 1 via a sliding hinge block 41.

[0047] The upper end of the outer support rod 212 is hinged to the abutment plate 1 via a sliding hinge block 41, and the lower end of the outer support rod 212 is hinged to the abutment plate 1 via a fixed hinge block 42.

[0048] This allows the left end of the support component 2 to move left and right on the slide rail 5, while the right end is a fixed structure that can only rotate relative to the abutment plate 1. When it is necessary to adjust the opening degree of the support device, it is only necessary to move the sliding hinge block 41.

[0049] Furthermore, the limiting locking assembly 3 includes an adjusting bolt 31 and a semi-circular adjusting disc 32, with the adjusting bolt 31 and the adjusting disc 32 slidably connected.

[0050] The adjusting plate 32 is fixedly mounted on the lower end of the outer support rod 212 with the rotating shaft 22 as the center. A semi-circular rotating groove 33 is provided on the adjusting plate 32.

[0051] The adjusting bolt 31 is fixedly mounted on the inner support rod 211 through the rotating groove 33. When the support assembly 2 moves, the adjusting bolt 31 rotates back and forth on the rotating groove 33 of the adjusting plate 32. When the desired position is reached, turning the adjusting bolt 31 can lock the relative movement between the adjusting bolt and the adjusting plate 32, that is, lock the inner support rod 211 and the outer support rod 212, thus completing the locking of the support device.

[0052] Furthermore, both the support component 2 and the limit locking component 3 are made of stainless steel, which effectively improves the support performance of the entire device and significantly reduces the safety hazards caused by corrosion and rust during on-site construction. It also improves the reliability of the limit locking component 3 and prevents the support device from being retracted due to accidents during the support process. The clamping plate 1 and the height adjustment component 4 are made of hard plastic. The hard plastic material meets the usage requirements while reducing the overall weight of the support device. At the same time, the hard plastic clamping plate 1 is less likely to cause damage to the operator or the maintenance port, thus improving the safety of the support device.

[0053] In use: First, place the folded ventilation duct access support device inside the access port that needs support. Then, by pushing the sliding hinge block 41, since one side of the support component 2 is connected to the fixed hinge block 42, the inner support rod 211 and the outer support rod 212 move relative to each other, raising the height of the entire support component 2. This adjusts the support device to a suitable height. After the upper and lower clamping plates 1 press against the upper and lower ends of the access port, rotate the adjusting bolt 31 to lock the adjusting disc 32 to lock the two inner support rods 211 and the two outer support rods 212, ultimately achieving the vertical support effect for the access port. Through the simple scissor-type structure design, the support device is reliable and quick to open and close, making it easy to store and carry. At the same time, the internal tension provided by the support allows the support device to apply the same force to the upper and lower access ports, more effectively preventing structural damage to the access port.

[0054] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
