Description

Technical Field

[0002] Interior decoration, also known as interior design, integrates modern science and technology with culture and art, and is closely related to architectural design, decorative art, ergonomics, psychology, and aesthetics. In terms of its research scope and object, interior decoration can be divided into home interior decoration, hotel interior decoration, store interior decoration, and public facility interior decoration. In interior decoration, a punching device is usually required to punch holes in the ceiling for subsequent decoration.

[0003] Since the existing method of drilling holes for interior decoration is mostly for construction workers to drill holes with a stepladder hand drill, it is obvious that this method will inevitably affect the efficiency of decorative ceiling drilling. Although drilling equipment is also used for drilling, most of them are to install the drill on the top of the support rod, and then manually push the support rod to enable the drill rod of the drill to drill holes in the ceiling. Obviously, although this method does not require construction workers to drill holes by climbing, since the depths of holes required for drilling in the ceiling area are different, it is difficult for construction workers to accurately control the depth and accuracy of the holes in the ceiling area, which will affect the efficiency of ceiling drilling.

[0015] In the present invention, the upward movement of the drilling machine is achieved by the rise of the lifting cylinder, and the extended length of the drill rod is fixed, the drilling machine only drives the drill rod to rotate rapidly. Therefore, when the top surface of the lifting cylinder hits the wall of the ceiling area, the depth of the hole drilled by the drill rod will also stop, and thus the phenomenon of deeper or shallower drilling depth will not occur due to the drilling machine's inability to stop moving in time or the inertia generated during the movement of the drilling machine when the drilling machine drives the drill rod to rise synchronously to drill holes in the ceiling area. At the same time, when the drilling is completed, the drill rod first withdraws from the hole, and the top surface of the lifting cylinder fits against the outer hole wall of the hole, which can protect the outer hole wall of the hole and prevent the drill rod from twisting faster when the drilling machine moves downward to drive the drill rod to disengage from the hole, causing the wall around the hole after the drilling to fall off, which not only affects the accuracy of the drilling, but also affects the aesthetics of the drilling.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 1-Figure 7 As shown, the present invention is a ceiling drilling device for indoor decoration, comprising a base 1, a support tube 2 is arranged on the base 1, and a connecting rod transmission mechanism 3 is connected to the top of the support tube 2, a lifting tube 4 is installed on the top of the connecting rod transmission mechanism 3, and a conversion lifting mechanism 5 is arranged in the lifting tube 4, a drilling machine 6 is installed inside the top of the lifting tube 4, and a drill rod 61 of the drilling machine 6 slides upward and extends into the outside of the lifting tube 4, which is used to perform a hole processing on the area to be suspended, the drilling machine 6 is connected to the conversion lifting mechanism 5, and a power drive mechanism 7 is arranged inside the base 1, and the power drive mechanism 7 drives the conversion mechanism to work through the connecting rod transmission mechanism 3;

[0029] In the scheme designed by the present invention, when it is necessary to drill holes in the area of ​​the suspended ceiling, the base 1 is pushed to the area to be drilled, and then the lifting cylinder 4 is installed to the top end of the connecting rod transmission mechanism 3, and then the bottom end of the connecting rod transmission mechanism 3 is installed on the supporting cylinder 2. At this time, according to the height of the suspended ceiling, multiple connecting rod transmission mechanisms 3 can be connected up and down in sequence, and then the top of the lifting cylinder 4 is close to the top of the suspended ceiling wall. At this time, the connecting rod transmission mechanism 3 will connect the conversion lifting mechanism 5 and the power drive mechanism 7, and then the construction personnel control the control panel on the base 1 to first drive the drilling machine 6 to rise in the lifting cylinder 4 through the conversion lifting mechanism 5, so that the rod body of the drill rod 61 extends upward from the outside of the lifting cylinder 4. When the rod body of the drill hole extends to a length sufficient to drill a hole, the drilling machine 6 is in a stopped rising state, and the drilling machine 6 works to make the drill rod 61 rotate rapidly, and then the conversion lifting mechanism 5 will control the lifting cylinder 4 to rise, so that it drives the rapidly rotating drill rod 61 to drill the drilling area, and when the lifting cylinder 4 After the top end of the drill rod 61 is attached to the top wall of the ceiling, the depth of the drill rod 61 drilling into the wall will no longer change, so that the depth and accuracy of the hole in the ceiling area can be accurately controlled. When the hole is drilled at this point, the reverse rotation drilling machine 6 is driven to descend in the lifting cylinder 4 by the conversion lifting mechanism 5, and the drill rod 61 will withdraw from the drill hole. At this time, since the top of the lifting cylinder 4 continues to fit the position of the drill hole, when the drill rod 61 is separated from the drill hole, there will be no debris falling off the wall around the drill hole, so that it can be further The drilling accuracy is not only improved, but also the aesthetics of the drilling can be improved. When the drill rod 61 is completely separated from the drilled hole, the lifting mechanism 5 is converted to drive the lifting cylinder 4 to descend, so that it is separated from the wall after the drilling, and then the base 1 is pushed to slide to the next drilling point for drilling. Therefore, not only the construction personnel do not need to hold the drilling machine 6 for climbing drilling, but also the drilling accuracy and efficiency of the drilling device of the present invention in the ceiling area can be improved, and the holes will not become larger or more inaccurate.

[0030] As an embodiment of the present invention, the connecting rod transmission mechanism 3 includes an intermediate pipe section 31, a connecting shaft tube 32, a support shaft 33, a plug pin block 34, a square plug block 35 and an internal threaded sleeve 36, the bottom end pipe mouth of the intermediate pipe section 31 is formed with a sleeve tube 37, and the outer ring surface of the sleeve tube 37 is a threaded ring, the upper end pipe mouth of the intermediate pipe section 31 is formed with a plug sleeve 38, and the plug sleeve 38 and the sleeve tube 37 are plugged and matched with each other, the intermediate pipe section 31 is rotatably installed with a connecting shaft tube 32 through a bearing, and the connecting shaft tube 32 is rotatably installed with a support shaft 33 through a bearing, and the length of the support shaft 33 is the same as the length of the connecting shaft tube 32. The two ends of the connecting shaft tube 32 are respectively located in the middle of the sleeve 37 and the plug sleeve 38. The top pipe opening of the connecting shaft tube 32 is provided with at least four plug pin blocks 34 in a circumferential array, and the bottom pipe opening is provided with at least four plug slots 321 in a circumferential array, and the plug slots 321 and the plug pin blocks 34 cooperate with each other. The top of the supporting shaft 33 is vertically fixed with a square plug block 35, and the bottom end is provided with a square plug hole 331, and the square plug hole 331 cooperates with the square plug block 35. The top outer ring surface of the intermediate pipe section 31 is threadedly connected with an internal thread sleeve 36, and the internal thread sleeve 36 is threadedly connected with the outer ring surface thread of the sleeve 37.

[0031] In the scheme designed by the present invention, when the two sections of the intermediate pipe section 31 need to be connected to each other to increase the height of the drilling machine 6, the sleeve 37 of the upper intermediate pipe section 31 is sleeved into the plug sleeve 38 of the lower intermediate pipe section 31, and the plug pin block 34 at the upper end of the lower connecting shaft tube 32 is correspondingly inserted into the plug groove 321 at the bottom end of the upper connecting shaft tube 32, so that the upper and lower connecting shaft tubes 32 are mutually transmission-connected, and at the same time, the square plug block 35 at the top end of the lower support shaft 33 is inserted into the square plug hole 331 opened at the bottom end of the upper support shaft 33, so that the upper and lower support shafts 33 can be mutually transmission-connected, and then the internal threaded sleeve 36 on the lower intermediate pipe section 31 is twisted to make it threadedly connected to the sleeve 37, The internal threaded sleeve 36 can connect and fix the upper and lower intermediate pipe sections 31 to each other without affecting the mutual transmission connection between the upper and lower connecting shaft tubes 32 and the support shaft 33, thereby facilitating the power drive mechanism 7 to normally drive the rotating lifting mechanism to work. At the same time, when the punching equipment is not needed to punch holes in the ceiling, the internal threaded sleeve 36 can be rotated in the opposite direction to rotate it downward to disengage from the internal threaded sleeve 36, and then the upper intermediate pipe section 31 can be directly pulled upward, so that the sleeve tube 37 will quickly disengage from the plug-in sleeve 38, and the upper and lower connecting shaft tubes 32 and the support shaft 33 will also quickly separate, thereby facilitating the rapid separation and disassembly of the interconnected intermediate pipe sections 31, and thus will not affect the normal punching of the decorative top by the drilling machine 6.

[0032] As an embodiment of the present invention, the support tube 2 is also rotatably mounted with a connecting shaft tube 32 and a supporting shaft 33 through bearings, and the supporting shaft 33 is rotatably mounted in the connecting shaft tube 32. The top of the support tube 2 is also provided with a sleeve tube 37 that is plugged into and matched with a plug-in sleeve 38, and the outer ring surface of the support tube 2 is threadedly connected with an internal threaded sleeve 36. The connecting shaft tube 32 and the supporting shaft 33 located in the support sleeve extend into the base 1 and are connected to the power drive mechanism 7. The bottom end of the lifting tube 4 is connected to the intermediate pipe section 31 through a supporting sleeve 41, and the outer ring surface of the supporting sleeve 41 is threadedly connected with the internal threaded sleeve 36 that is threadedly connected to the top outer ring surface of the intermediate pipe section 31.

[0033] In the scheme designed by the present invention, when it is necessary to connect the lifting cylinder 4, the intermediate pipe section 31 and the supporting cylinder 2 to each other so that the drilling machine 6 is supported to the ceiling area to be drilled, the bottom end of the intermediate pipe section 31 will be sleeved onto the top end of the supporting cylinder 2, and the connecting shaft tube 32 and the supporting shaft 33 in the supporting cylinder 2 are connected in the same manner as the connecting shaft tube 32 and the supporting shaft 33 in the intermediate pipe section 31. Then, the internal threaded sleeve 36 on the supporting cylinder 2 is twisted to quickly connect the intermediate pipe section 31 to the supporting cylinder 2, and then the supporting sleeve 41 at the bottom of the lifting cylinder 4 is sleeved into the plug-in sleeve 38 at the top of the intermediate pipe section 31, and the tubular screw rod 5 in the conversion lifting mechanism 5 is also 1 and the transmission shaft 53 are connected to the connecting shaft tube 32 and the supporting shaft 33 in the same manner, so that the supporting tube 2, the intermediate pipe section 31 and the supporting sleeve 41 are quickly connected to each other, and at the same time, the connection between the connecting shaft tube 32 and the tubular screw rod 51, the normal connection between the supporting shaft 33 and the transmission shaft 53 are not affected, so that the power drive mechanism 7 can drive the tubular screw rod 51 and the transmission shaft 53 normally respectively. After the use of the punching device is completed, the supporting tube 2, the intermediate pipe section 31 and the supporting sleeve 41 can also be quickly disassembled and separated, so that the overall height of the punching device can be reduced, which is convenient for the punching device to be normally moved and transported in a small space.

[0034] As an embodiment of the present invention, the conversion lifting mechanism 5 includes a tubular screw 51, a connecting plate 52, a transmission shaft 53, a square block 54, a support screw 55, a support plate 56, a support rod 57, a fixed plate 58 and a guide slider 59. The tubular screw 51 is connected to the top of the connecting shaft tube 32 through a connecting tube, and the outer ring surface of the tubular screw 51 is connected to the sleeved connecting plate 52 through a screw nut, and the outer ring surface of the connecting plate 52 is connected to the inner cylinder wall of the lifting cylinder 4. The transmission shaft 53 is rotatably installed inside the tubular screw 51 through a bearing, and the bottom end surface of the transmission shaft 53 is connected to the support shaft 33. The top end surface of the transmission shaft 53 is vertically fixed with a square block 54, and the bottom end surface of the support screw 55 is provided with a square upward. shaped hole 551, and a square block 54 is slidably inserted in the square hole 551, the outer ring surface of the support screw 55 is sleeved with a support plate 56 through a screw nut, at least four vertical support rods 57 are installed in a circumferential array on the support plate 56, and a fixed plate 58 is fixed to the top end surface of the four support rods 57, and a drilling machine 6 is installed on the upper surface of the fixed plate 58, the inner cylinder wall of the lifting cylinder 4 is provided with a plurality of vertical guide grooves 42 in a circumferential array from the top end to the bottom, and a guide slider 59 is slidably arranged in each vertical guide groove 42, and a plurality of the guide sliders 59 are fixed to the outer ring surface of the fixed plate 58, and an electromagnetic suction strip is insulated on the wall surface of the vertical guide groove 42, and the guide slider 59 is made of metal and is insulated and connected to the fixed plate 58;

[0035] In the scheme designed by the present invention, when the drilling machine 6 needs to slide up and down in the lifting cylinder 4 to adjust the length of the drill rod 61 extending out of the lifting cylinder 4, the power drive mechanism 7 is required to first drive the support shaft 33 to rotate, and then the transmission shaft 53 will drive the support screw to rotate through the cooperation of the square block 54 and the square hole 551, and then the support plate 56 will drive the drilling machine 6 to slide up and down in the lifting cylinder 4 through multiple support rods 57 and the fixed plate 58, so as to facilitate the adjustment of the length of the drill rod 61 extending out of the outside of the lifting cylinder 4, so as to realize different depth drilling processing on the ceiling. When the fixed plate 58 rises and slides in the lifting cylinder 4, the multiple guide sliders 59 will be in the multiple vertical guide grooves 4 2, the electromagnetic suction strip is powered off and disengages from the adsorption and fixation of the metal guide slider 59, so that when the support screw 55 drives the support plate 56 to rotate, the fixed plate 58 will not drive the drilling machine 6 to rotate in the lifting cylinder 4; when the drill rod 61 is extended to a specified length, the guide slider 59 will be fixedly adsorbed into the vertical guide groove 42 through the energized electromagnetic suction strip, so that the fixed plate 58 can be fixedly connected to the lifting cylinder 4, and then the power drive mechanism 7 drives the connecting shaft tube 32 to rotate separately, so that it drives the lifting cylinder 4 to move upward through the cooperation of the tubular screw rod 51 and the connecting plate 52, and then the drilling machine 6 will drive the extended drill rod 61 to rotate quickly, so that The drilling operation is performed at the position where the ceiling area needs to be drilled, and since the upward movement of the drilling machine 6 is achieved by the rise of the lifting cylinder 4, and the extended length of the drill rod 61 is certain, the drilling machine 6 only drives the drill rod 61 to rotate quickly. Therefore, when the top surface of the lifting cylinder 4 hits the wall of the ceiling area, the depth of the hole drilled by the drill rod 61 will also stop, and then the drilling machine 6 will not drive the drill rod 61 to rise synchronously to drill a hole in the ceiling area. Due to the inability of the drilling machine 6 to stop moving in time or the inertia generated during the movement of the drilling machine 6, the depth of the hole will not be deeper or shallower. At the same time, when the drilling is completed, the drill rod 61 withdraws from the hole. The lifting cylinder 4 that is in contact with the hole continues to be attached to the wall surface of the hole, so that the support screw 55 drives the support plate 56 to move downward, and then the fixed plate 58 will drive the reverse rotating drilling machine 6 to move downward in the lifting cylinder 4. At this time, the guide slider 59 slides downward in the vertical guide groove 42, and then the drill rod 61 is first separated from the hole, and the top surface of the lifting cylinder 4 is attached to the outer hole wall of the hole, which can protect the outer hole wall of the hole and prevent the drilling machine 6 from moving downward to drive the drill rod 61 to separate from the hole. The faster the twisting of the drill rod 61 causes the wall around the hole after the hole is drilled to fall off, which not only affects the accuracy of the drilling, but also affects the aesthetics of the drilling.

[0036] As an embodiment of the present invention, a plurality of vertical guide rods 591 are installed in a circumferential array on the top surface of the support sleeve 41, and each vertical guide rod 591 is slidably inserted into the guide sliding hole 43 opened on the upper and lower walls of the lower cylinder mouth of the lifting cylinder 4, and the top surface of the square block 54 is connected to the hole wall of the square hole 551 through a spring;

[0037] In the scheme designed by the present invention, in order to prevent the lifting cylinder 4 from rotating when the tubular screw rod 51 drives the lifting cylinder 4 to rise or fall through the connecting plate 52, the support sleeve 41 is slidably inserted into the multiple guide sliding holes 43 through multiple vertical guide rods 591, so that it does not interfere with the normal rise or fall of the lifting cylinder 4, and the lifting cylinder 4 will not rotate; the transmission shaft 53 and the support screw 55 are connected by the square block 54 and the square hole 551 to realize the transmission connection, so that it does not affect the support screw 55 driving the fixed plate 58 to slide up and down, and does not interfere with the lifting cylinder 4 when it rises. The support screw 55 is driven by the fixed plate 58, the support rod 57 and the support plate 56 to move upward synchronously, so that the drill rod 61 is punched, and the square block 54 and the support screw 55 are connected by a spring to facilitate the support screw 55 to return to the initial position.

[0038] As an embodiment of the present invention, the power drive mechanism 7 includes a first gear 71, a second gear 72, a transmission gear 73, an electric lifting rod 74 and a meshing gear 75, the first gear 71 is fixedly sleeved on the connecting shaft tube 32 extending into the base 1, the second gear 72 is fixedly sleeved on the supporting shaft 33 extending into the base 1, and the second gear 72 is located below the first gear 71, the first gear 71 and the second gear 72 have the same size, the transmission gear 73 is connected to the piston rod of the vertically arranged electric lifting rod 74 through a transmission shaft, and the transmission gear 73 is slidably meshed with the first gear 71 and the second gear 72, the rod body of the electric lifting rod 74 is connected to the output shaft of the servo motor fixed inside the base 1, the meshing gear 75 is also connected to the piston rod of the electric lifting rod 74 through a transmission shaft, and the rod body of the electric lifting rod 74 is fixedly connected to the base 1, and the meshing gear 75 is slidably meshed with the first gear 71 and the second gear 72;

[0039] In the solution designed by the present invention, when the connecting shaft tube 32 needs to be rotated, the piston rod of the electric lifting rod 74 connected to the driving transmission gear 73 is extended, so that the driving transmission gear 73 is engaged with the first gear 71, and then the fixed servo motor output shaft will drive the connecting shaft tube 32 to rotate through the engagement of the transmission gear 73 and the second gear 72, and at this time the meshing gear 75 will move downward through another electric lifting rod 74 to mesh with the second gear 72, so that the support shaft 33 is fixed through the engagement of the second gear 72 and the meshing gear 75. The support screw 55 is fixed so that when the lifting cylinder 4 is lifted normally, the support screw 55 will not rotate. When the support shaft 33 needs to rotate, the piston rod of the electric lifting rod 74 contracts, so that the driving transmission gear 73 is engaged with the second gear 72, thereby facilitating the driving of the support shaft 33 to rotate, and the piston rod of the other electric lifting rod 74 extends, so that the driving meshing gear 75 is engaged with the second gear 72. At this time, the connecting shaft tube 32 will be in a fixed state, thereby preventing the lifting cylinder 4 from rising and falling synchronously when the drilling machine 6 rises or falls in the lifting cylinder 4.
