Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine air ducts, and particularly relates to an air duct hook with anti-fall-off convex points. Background Art

[0002] During the coal mining process, it is necessary to maintain good ventilation conditions, and air ducts are needed for ventilation. Air ducts are installed by hanging them through hooks.

[0003] The existing hair dryer hook does not have an effective limit and anti-detachment mechanism when in use. Therefore, if the hair dryer shakes during ventilation, the hair dryer and the hook may easily become detached, which results in certain insecurities and limitations in use. Utility Model Content

[0004] The purpose of the utility model is to provide a hair dryer hook with an anti-detachment protrusion to solve the problem that the existing hair dryer hook proposed in the above background technology has no effective limiting and anti-detachment mechanism when in use. Therefore, if the hair dryer shakes during ventilation, the hair dryer and the hook are easily detached, which leads to certain insecurity and limitations in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a hair dryer hook with an anti-slip protrusion, comprising a hook body, the hook body having two hanging areas, one above and one below, the hook body having two anti-slip protrusions fixed at the hanging area position directly below the hook body, the two anti-slip protrusions are arranged relatively to each other, one side of the anti-slip protrusion is slidably installed with a limit lock plate, and the other side of the anti-slip protrusion is fixedly installed with a limit lock sleeve, the limit lock plate is inserted into the limit lock sleeve at the same side position, the rotating shaft is rotatably installed on the hook body at the hanging area position directly above, the outer surface of the rotating shaft is fixedly installed with a blocking plate, a fixing rod is fixedly installed on the hook body at a position parallel to the rotating shaft, the blocking plate is provided with a bayonet for the fixing rod to be snapped in, the outer surface of the fixing rod has a thread and a fixing nut is threadedly installed, and a tightening plate is movably provided on the blocking plate.

[0006] The above scheme is adopted, by setting the anti-slip protrusion in conjunction with the limit lock plate and the limit lock sleeve, the setting of the anti-slip protrusion can play a preliminary anti-slip and anti-detachment effect when the air duct is hung in the hanging area below the hook body, and is used in conjunction with the limit lock plate and the limit lock sleeve to realize the connection of the two anti-slip protrusions, further preventing slip and anti-detachment, and ensuring good stability in installation and use of the air duct. By setting the blocking plate in conjunction with the fixing rod and the fixing nut, when the hanging area above the hook body is hung in the installation position, the blocking plate is used in conjunction with the fixing rod and the fixing nut to achieve the closure of the hanging area above the hook body, and the mounting position is tightened with the tightening plate to ensure the installation stability of the hook body and avoid accidental loosening.

[0007] As a preferred embodiment, a fixing plate is fixedly installed on the side of the anti-slip protrusion on the same side as the limit lock plate, and a guide rod is slidably installed on the fixing plate. One end of the guide rod is fixedly connected to the limit lock plate, and the other end of the guide rod is fixedly installed with a limit disk.

[0008] By adopting the above scheme, the fixed plate is used in conjunction with the guide rod. The sliding of the guide rod can drive the limit lock plate to move synchronously. The guide rod can ensure that the limit lock plate slides stably and is not easy to shake. The limit plate can prevent the guide rod from separating from the fixed plate when sliding, thereby playing an effective limit role.

[0009] As a preferred embodiment, a spring is sleeved on the outside of the guide rod, and two ends of the spring are fixedly connected to the opposite surfaces of the limit lock plate and the fixed plate respectively.

[0010] With the above solution, when the limiting lock plate is separated from the limiting lock sleeve, the spring is in a deformed state, so the elasticity of the spring can be used to drive the limiting lock plate to move quickly and insert into the limiting lock sleeve.

[0011] As a preferred embodiment, the end of the limit lock plate has an inclined surface, and the inclined surface is arranged upward.

[0012] By adopting the above solution, by providing an inclined surface, the inclined surface will be squeezed when the air duct is installed, thereby driving the limit lock plate to slide, thereby improving the convenience of installing the air duct and the hook body.

[0013] As a preferred embodiment, a slide is fixedly installed on the lower surface of the tightening plate, a plate sleeve is fixedly installed on the side of the blocking plate, the slide slides through the plate sleeve and a pin is inserted into the plate sleeve, and a plurality of slots for use with the pin are opened on the side of the slide.

[0014] By adopting the above solution, the slide plate is used in conjunction with the plate sleeve to slide and adjust the position of the tightening plate and lock it with the pin and slot, thereby locking the installation position of the hook body.

[0015] As a preferred embodiment, the outer surface of the fixing rod is provided with a limiting ring, the side of the limiting ring is fixedly installed with a locking plate, the side of the blocking plate is provided with a locking groove for the locking plate to be locked in, and the fixing nut is arranged on the side of the limiting ring.

[0016] By adopting the above solution and using the limiting ring in conjunction with the positioning plate, the position of the blocking plate in a horizontal state can be limited to avoid accidental loosening.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The air duct hook with anti-slip protrusion is used in conjunction with the limit lock plate and the limit lock sleeve by providing an anti-slip protrusion. The anti-slip protrusion can play a preliminary anti-slip and anti-slip effect when the air duct is hung in the hanging area below the hook body. The anti-slip protrusion is used in conjunction with the limit lock plate and the limit lock sleeve to achieve the connection of the two anti-slip protrusions, further preventing slipping and preventing falling, and ensuring good stability in installation and use of the air duct.

[0019] The air duct hook with anti-drop protrusions is used by setting a blocking plate in conjunction with a fixing rod and a fixing nut. When the hanging area above the hook body is hung in the installation position, the blocking plate is used in conjunction with the fixing rod and the fixing nut to close the hanging area above the hook body, and the mounting position is tightened with the tightening plate to ensure the installation stability of the hook body and avoid accidental loosening.

The two anti-slip protrusions 2 are arranged relatively to each other, and a limited locking plate 3 is slidably installed on the side of one of the anti-slip protrusions 2, and a limited locking sleeve 4 is fixedly installed on the side of the other anti-slip protrusion 2. The limited locking plate 3 is inserted into the limited locking sleeve 4 at the same side position. A rotating shaft 5 is rotatably installed at the hanging area position facing the top of the hook body 1, and a blocking plate 6 is fixedly installed on the outer surface of the rotating shaft 5. A fixing rod 7 is fixedly installed at a position on the hook body 1 that is flush with the rotating shaft 5, and a bayonet for the fixing rod 7 to be snapped in is opened on the blocking plate 6. The outer surface of the fixing rod 7 has a thread and a fixing nut 8 is threadedly installed. A tightening plate 9 is movably provided on the blocking plate 6.

[0027] A fixing plate 10 is fixedly installed on the side of the anti-slip protrusion 2 on the same side as the limit lock plate 3, and a guide rod 11 is slidably installed on the fixing plate 10. One end of the guide rod 11 is fixedly connected to the limit lock plate 3, and the other end of the guide rod 11 is fixedly installed with a limit disk. The fixing plate 10 is used in conjunction with the guide rod 11. The sliding of the guide rod 11 can drive the limit lock plate 3 to move synchronously. The guide rod 11 can ensure that the limit lock plate 3 slides stably and is not easy to shake. The limit disk can prevent the guide rod 11 from separating from the fixing plate 10 when sliding, thereby playing an effective limit role.

[0028] A spring 12 is provided on the outer sleeve of the guide rod 11, and the two ends of the spring 12 are fixedly connected to the opposite surfaces of the limit lock plate 3 and the fixed plate 10 respectively. When the limit lock plate 3 is separated from the limit lock sleeve 4, the spring 12 is in a deformed state, so the elasticity of the spring 12 can be used to drive the limit lock plate 3 to move quickly and insert into the limit lock sleeve 4.

[0029] The end of the limit lock plate 3 has an inclined surface, and the inclined surface is arranged upward. By setting the inclined surface, the inclined surface will be squeezed when the air duct is installed, thereby driving the limit lock plate 3 to slide, thereby improving the convenience of installing the air duct and the hook body 1.

[0030] A slide plate 13 is fixedly installed on the lower surface of the tightening plate 9, and a plate sleeve 14 is fixedly installed on the side of the blocking plate 6. The slide plate 13 slides through the plate sleeve 14 and a latch 15 is inserted into the plate sleeve 14. Several slots for cooperating with the latch 15 are opened on the side of the slide plate 13. The slide plate 13 is used in conjunction with the plate sleeve 14 to slide and adjust the position of the tightening plate 9 and lock it in conjunction with the latch 15 and the slot, thereby realizing the locking of the installation position of the hook body 1.

[0031] The outer surface of the fixing rod 7 is sleeved with a limiting ring 16, and a locking plate 17 is fixedly installed on the side of the limiting ring 16. A locking groove for the locking plate 17 to be locked in is opened on the side of the blocking plate 6. The fixing nut 8 is arranged in a close fit on the side of the limiting ring 16. The limiting ring 16 is used in conjunction with the locking plate 17 to limit the position of the blocking plate 6 in a horizontal state to avoid accidental loosening.

[0032] After the cam 1 is in the upright position, the locking plate 17 is locked in the locking groove, and the locking nut 8 is screwed on to fix the blocking plate 6 in the horizontal position. Then, the latch 15 is pulled out and the top plate 9 is moved upward, so that the top plate 9 presses against the surface of the mounting position, and the latch 15 is inserted to fix the mounting position of the hook body 1 without loosening. Then, the air duct is inserted into the hanging area below the hook body 1. During insertion, the inclined surface of the limit lock plate 3 will separate the limit lock plate 3 from the limit lock sleeve 4, and then the air duct will enter the hanging area below the hook body 1 through the two anti-slip protrusions 2. At the same time, the spring 12 will drive the limit lock plate 3 to reset and lock the limit lock sleeve 4.
