[0002] Air ducts are pipes used to transport air. To facilitate transportation and installation, air ducts are usually installed in sections. To ensure the airtightness of the connection between two adjacent sections, they are usually connected by tie bolts, and rubber gaskets are installed on the raised edge of the air duct. The two rubber gaskets between the two sections fit together to seal the gap between them.

[0003] During the duct manufacturing process, the duct's flange will first have a through hole drilled, and then the flange will be welded onto the duct. Subsequently, the rubber gasket will be installed on the edge. At this time, the rubber gasket needs to have a mating hole drilled so that the mating hole corresponds to the through hole.

[0004] Currently, drilling holes in rubber pads is done using drilling machines. Workers not only need to hold the drilling machine to drill holes one by one, but also need to observe the position of the through holes to ensure that the holes on the mating rubber pad correspond to the positions of the through holes, resulting in low drilling efficiency for rubber pads.

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1 to 5 As shown, a duct rubber pad drilling tool includes: a bracket 1, a drill 2, a connecting plate 3, and a positioning rod 4; the bracket 1 is detachably installed on the protruding edge of the duct; the bracket 1 includes a U-shaped plate 1.1 and an L-shaped plate 1.2, the top end of the L-shaped plate 1.2 being fixedly connected to the bottom end of the U-shaped plate 1.1; the drill 2 is slidably installed on the bracket 1 in the height direction; the connecting plate 3 is slidably engaged with the drill 2 in the height direction, and the connecting plate 3 is slidably installed inside the bracket 1; the top end of the positioning rod 4 is fixedly installed on the bottom right end of the connecting plate 3, and the positioning rod 4 can be inserted into the pre-drilled hole in the rubber pad.

[0024] When drilling holes in the rubber pad, place the L-shaped plate 1.2 against the raised edge of the ground and the U-shaped plate 1.1 above the raised edge to complete the installation of the bracket 1. When drilling the first hole, manual positioning is required. After drilling the first hole, pull the bracket 1 to move on the raised edge. When the positioning rod 4 moves into the hole that has been drilled on the rubber pad, the positioning rod 4 is inserted into the hole and moves the connecting plate 3 down. The drill rig 2 is restricted by the connecting plate 3 and cannot move further. At this time, it means that the hole to be drilled is below the drill rig 2. At this time, press down the drill rig 2 to drill the rubber pad. After the rubber pad is drilled, raise the drill rig 2 and pull the positioning rod 4 out from the hole that has been drilled on the rubber pad. Move the bracket 1 as a whole so that the drill rig 2 moves to the next position to be drilled.

[0025] The end of the drill rig 2 is detachably equipped with a slider 5, which is slidably mounted on the bracket 1. A pressing cylinder 5.1 is provided below the slider 5. The pressing cylinder 5.1 is sleeved on the outside of the drill bit of the drill rig 2. A spring 5.2 is fixedly connected between the pressing cylinder 5.1 and the slider 5. The spring 5.2 is sleeved on the outside of the drill bit of the drill rig 2.

[0026] Before use, install the drill 2 on the slider 5. When the drill 2 moves downward, it can drive the slider 5 to move downward. The slider 5 drives the pressing cylinder 5.1 on the spring 5.2 to move downward. When the pressing cylinder 5.1 contacts the surface of the rubber pad, it continues to press down on the drill 2, causing the spring 5.2 to be compressed. At this time, the pressing cylinder 5.1 is subjected to the elastic force of the spring 5.2 and will press tightly against the rubber pad, pressing the drilling point of the drill 2, so that the drill 2 can be more stable when drilling.

[0027] The slider 5 is located inside the U-shaped plate 1.1. Limiting blocks 5.3 are fixedly installed at both ends of the slider 5 near the inner wall of the U-shaped plate 1.1. Slide grooves 1.3 are opened at both ends of the U-shaped plate 1.1. The two limiting blocks 5.3 are slidably installed in the two slide grooves 1.3 respectively.

[0028] When the drill rig 2 slides in the height direction, the limiting block 5.3 slides in the slide groove 1.3, so that the drill rig 2 remains stable when sliding, and at the same time, it can keep the drill rig 2 in a vertical position for use.

[0029] The pressing cylinder 5.1 is provided with pressing plates 5.4 at both ends, and the bottom surfaces of the two pressing plates 5.4 are at the same height as the bottom surface of the pressing cylinder 5.1.

[0030] When the pressing cylinder 5.1 moves, it can drive the pressing plate 5.4 to move. At the same time, when the pressing cylinder 5.1 presses the rubber pad, it can make the pressing plate 5.4 fit tightly against the rubber pad, so that the drilling machine 2 can be more stable during use. When the pressing plate 5.4 moves, it can drive the positioning rod 4 to move in the height direction, so that the positioning rod 4 can be pulled out from the drilled hole.

[0031] Movable hooks 6 are slidably installed on the top surfaces of both pressing plates 5.4, with the hook heads of both movable hooks 6 facing the positioning rod 4. Sliding rods 6.1 are fixedly installed on both sides of the top of the movable hooks 6. Both ends of the U-shaped plate 1.1 are provided with right-angled trapezoidal guide grooves 1.4. The bottom end of the guide groove 1.4 is connected to a straight groove 1.5 on the side facing the positioning rod 4. The sliding rods 6.1 are slidably installed in the guide grooves 1.4. Fixing plates 6.2 are fixedly installed on both sides of the movable hooks 6, and the fixing plates 6.2 fix the two movable hooks 6 together. The right end of the fixing plate 6.2 is fixedly connected to the connecting plate 3.

[0032] The inclined groove of guide groove 1.4 is parallel to the hook head of movable hook 6. Fixed plate 6.2 passes through both sides of pressing cylinder 5.1. Movable hook 6 slides in straight groove 1.5 via sliding rod 6.1 and enters guide groove 1.4, which can drive fixed plate 6.2 to move vertically. When fixed plate 6.2 moves, it can drive connecting plate 3 to move, so that positioning rod 4 can be pulled out from the drilled hole. When sliding rod 6.1 slides into inclined groove of guide groove 1.4, positioning rod 4 can be displaced obliquely upward and laterally away from hole. When the sliding rod 6.1 moves to the top of the guide groove 1.4, the positioning rod 4, which is suspended in the air, will move downwards under the influence of gravity, allowing it to contact the rubber pad. At this time, the sliding rod 6.1 is in the vertical groove on the side of the guide groove 1.4 away from the positioning rod 4. When the positioning rod 4 moves above the hole, it will fall into the hole under the influence of gravity, thus positioning the hole. At this time, the sliding rod 6.1 is located at the bottom of the guide groove 1.4. When the drilling rig 2 presses down, the sliding rod 6.1 slides in the straight groove 1.5.

[0033] Limiting blocks 6.3 are fixedly installed at the bottom ends of the two movable hooks 6. Slide grooves 5.7 are provided on the two pressing plates 5.4. The two limiting blocks 6.3 are slidably installed in the two slide grooves 5.7 respectively. A spring 6.4 is fixedly installed on the side of the movable hook 6 away from the positioning rod 4. An mounting plate 5.5 is fixedly installed on the end of the spring 6.4 away from the movable hook 6. The bottom end of the mounting plate 5.5 is fixedly connected to the top surface of the pressing plate 5.4.

[0034] When the movable hook 6 slides within the slide groove 5.7 via the limiting block 6.3, it compresses the spring 6.4. When the spring 6.4 returns to its original position, it can reset the movable hook 6.

[0035] Both ends of the slider 5 are fixedly installed with fixing hooks 5.6. The hook heads of the two fixing hooks 5.6 are far away from the positioning rod 4. The fixing hooks 5.6 on the same side can engage with each other.

[0036] When the drill rig 2 presses down, it compresses spring 5.2 and moves the fixed hook 5.6 downward, so that the inclined surface of the fixed hook 5.6 contacts the inclined surface of the movable hook 6. Due to the squeezing force of the inclined surface, the movable hook 6 will move away from the positioning rod 4 and compress spring 6.4. When the fixed hook 5.6 is smaller than the movable hook 6 in the height direction, spring 6.4 will reset and make the fixed hook 5.6 engage with each other. At this time, spring 5.2 is in a compressed state.

[0037] When the drilling rig 2 is raised, the fixed hook 5.6 moves the movable hook 6 upward, causing the positioning rod 4 to move upward and be pulled out of the hole. At this time, the sliding rod 6.1 slides from the straight groove 1.5 into the guide groove 1.4. When the sliding rod 6.1 moves into the inclined groove of the guide groove 1.4, since the inclined groove of the guide groove 1.4 is parallel to the movable hook 6, the movable hook 6 moves along the inclined groove of the guide groove 1.4 and disengages from the fixed hook 5.6. At this time, the sliding rod 6.1 is at the apex of the guide groove 1.4 and is subjected to the action of the spring 5.2 and gravity. This causes the positioning rod 4 to move downwards, at which point the positioning rod 4 contacts the rubber pad. When the support 1 is moved, the positioning rod 4 moves above the hole, and the spring 5.2 continues to reset, inserting the positioning rod 4 into the already drilled hole to achieve the positioning effect of the drill 2. At this time, the sliding rod 6.1 is at the bottom of the guide groove 1.4. The support 1 is moved further, causing the sliding rod 6.1 to slide to the connection between the straight groove 1.5 and the guide groove 1.4. At this time, the drill 2 cannot move, indicating that the positioning of the drill 2 is complete, and the drill 2 is pressed down, causing the drill 2 to perform drilling operations on the rubber pad.

[0038] Both sides of the U-shaped plate 1.1 are provided with rollers 1.6, which are used to roll on the rubber pad.

[0039] The roller 1.6 allows the bracket 1 to slide on the rubber pad and adjust the drilling position.

[0040] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
