Description

TECHNICAL FIELD

[0001] The present application relates to a building construction tool, in particular to a power conversion mechanism of a glue spraying and dust blowing integrated electric gun. BACKGROUND

[0002] The anchoring of steel bars, also known as the anchoring of steel bars, is a connecting technology that uses the locking force of structural glue to achieve anchoring of steel bars. It is the best choice for structural anchoring and heavy load anchoring. The process is as follows: first, drill holes in the concrete, wall rock and other base materials, then clean the holes, inject glue and other processes, and finally insert steel bars or profiles into the holes. After the glue solidifies, the steel bars and the base material are bonded together to achieve building structure anchoring. Among them, hole cleaning is a very important part of anchoring, because there will be a lot of concrete residue and dust in the hole after drilling. If the debris in the hole is not cleaned, it will directly affect the quality of the anchoring.

[0003] In the prior art, hole cleaning and glue injection are usually completed in two processes. First, use a blower or a brush to clean the concrete residue and dust in the hole. After the hole is cleaned, use an anchoring glue machine to inject anchoring glue. Such an operation process is relatively cumbersome, time-consuming and low in work efficiency. The operator needs to carry multiple tools when working, which is not portable.

[0004] To overcome the above defects of cleaning holes and injecting glue in steps, the applicant plans to develop an electric construction device that integrates hole cleaning and dust removal and hole injection. In the device, dust removal is achieved based on the blowing principle, and glue injection is achieved by pushing the rear end of the anchoring glue bottle with a glue pushing assembly. To simplify the product structure, the two operations share a power source to achieve automatic driving. Therefore, it is urgent to design a power switching mechanism to enable a single power source to drive the glue pushing assembly for glue injection or the blowing assembly for dust removal in a selective manner.

[0028] As

[0029] As Figure 4As shown in the figure, a glue spraying and dust blowing integrated electric gun A is provided with a shell assembly, and a base body 3 of a power switching mechanism is separately assembled in the shell assembly or directly integrally formed with the shell assembly. In this embodiment, the base body 3 is integrally formed with the shell assembly.

[0030] Further, as shown in the figures Figure 3 and 6 , the base body 3 is provided with a motor 1, and the motor 1 is combined with Figure 1 It can be seen that the motor 1 has an output shaft 1a, and the output shaft 1a is sequentially sleeved with a switching assembly 2, a glue spraying transmission part 1b and a dust blowing transmission part 1c; the two sides of the motor 1 away from the output shaft 1a are provided with connecting rods 1d, and the motor 1 is rotationally connected with the base body 3 through the connecting rods 1d; the switching assembly 2 can slide up and down relative to the base body 3, and up and down driving the switching assembly 2 can drive the output shaft 1a to swing up and down in space.

[0031] Based on the above structure design, as shown in the figures Figure 3 and 4 , in the glue spraying and dust blowing integrated electric gun A, a glue pushing assembly 4 is located above the glue spraying transmission part 1b, and a blowing assembly 5 is located below the dust blowing transmission part 1c; downward driving the switching assembly 2 can drive the output shaft 1a to swing downward in space, so as to drive the dust blowing transmission part 1c to be in transmission connection with the blowing assembly 5, thereby realizing dust blowing and hole cleaning; upward driving the switching assembly 2 can drive the output shaft 1a to swing upward in space, so as to drive the glue spraying transmission part 1b to be in transmission connection with the glue pushing assembly 4, thereby realizing glue spraying, that is, by up and down driving the switching assembly 2, the motor 1 can drive the glue pushing assembly 4 to spray glue or drive the blowing assembly 5 to blow dust in a selective manner.

[0032] Further, as shown in the figures Figure 1 , 2 and 3, the switching assembly 2 includes a manipulating assembly 21 and a lock 2c, the manipulating assembly 21 has a connecting part 2a sleeved on the output shaft 1a and a switching part 2b extending from the side of the base body 3, and the lock 2c is assembled on the side of the base body 3 and can fix the switching part 2b to be kept at two different height positions, that is, to keep the dust blowing transmission part 1c in transmission connection with the blowing assembly 5 or to keep the glue spraying transmission part 1b in transmission connection with the glue pushing assembly 4, so as to ensure that the dust blowing work or the glue spraying work of the glue spraying and dust blowing integrated electric gun A can be stably performed.

[0033] Please refer to Figure 2 , the side of the base body 3 is provided with an assembly hole 3a matched with the switching part 2b, and in this embodiment, the assembly hole 3a is a rectangular hole, the width of the rectangular hole is slightly larger than the width of the switching part 2b, and the switching part 2b is provided with a downward recessed sliding groove 2b2 at the position corresponding to the assembly hole 3a, so that the switching part 2b can move up and down in the assembly hole 3a. Further combined with Figure 7It can be seen that the end of the connecting part 2a is provided with a rotating shaft 2a1, and the switching part 2b is rotatably connected with the connecting part 2a through the rotating shaft 2a1, so that the switching part 2b can be inclined forward and backward relative to the connecting part 2a, thereby ensuring that the switching part 2b can slide up and down in the assembly hole 3a without being limited. If the connecting part 2a and the switching part 2b are fixedly installed, when the switching part 2b drives the motor 1 to rotate up and down with the connecting rod 1d as the axis, the switching part 2b will also be inclined to move, at this time the rectangular hole will limit the movement of the switching part 2b, only by setting a larger assembly hole 3a can ensure that the switching part 2b moves without being limited, but the larger assembly hole 3a will affect the appearance of the equipment.

[0034] As shown in Figure 7 , in the present embodiment, the outer end of the switching part 2b is provided with a hand-held part k, and the switching part 2b can be switched back and forth between two different height positions by up and down the hand-held part k. Further, as shown in Figure 1 and 7 , in order to ensure that the operating assembly 21 can more smoothly control the upward inclination of the output shaft 1a in space, the connecting part 2a of the operating assembly 21 is rotatably sleeved on the output shaft 1a through the bearing m, and the switching part 2b is slidably installed in the assembly hole 3a. In this way, the rotation of the output shaft 1a can be ensured not to be interfered by the operating assembly 21, and the switching part 2b can be ensured to be straight up and down switching operation.

[0035] Further referring to Figure 2 and 5 , the switching part 2b is provided with two sets of positioning holes 2b1 distributed upward and downward, the locking device 2c is slidably provided with a limiting part 2c1, the outer end of the limiting part 2c1 has a limiting part a protruding from the locking device 2c, and the inner end abuts against an elastic part 2c2. The pushing force of the elastic part 2c2 can make the limiting part a inserted into the positioning hole 2b1. When the limiting part a is inserted into the upper positioning hole 2b1, the motor 1 can drive the blowing assembly 5 to dust. When the limiting part a is inserted into the lower positioning hole 2b1, the motor 1 can drive the glue pushing assembly 4 to glue. Further referring to Figure 5 , the lower part of the locking device 2c is provided with a push rod 2c3, which drives the limiting part 2c1 to overcome the resistance of the elastic part 2c2, so that the limiting part a exits the positioning hole 2b1. In the present embodiment, the elastic part 2c2 is a compression spring.

[0036] Further, as shown in Figure 5 , the locking device 2c is provided with a horizontal assembly channel b, a circular arc transition channel c and a vertical assembly channel d which are communicated in sequence, the limiting part 2c1 has an unlocking part e which is slidably arranged in the horizontal assembly channel b, the push rod 2c3 is slidably arranged at the lower end of the vertical assembly channel d, and the vertical assembly channel d is arrayed with a plurality of balls f.

[0037] When the height of the switching part 2b needs to be adjusted, the push rod 2c3 is pushed upward, the top end of the push rod 2c3 pushes the ball f through the circular arc transition channel c to press the unlocking part e, the unlocking part e slides backward to drive the limiting part 2c1 to slide backward against the resistance of the compression spring, so that the limiting part a exits the current positioning hole 2b1, and then switches to another positioning hole 2b1. After releasing the pushing force on the push rod 2c3, the push rod 2c3 and the ball f fall back to the initial position under the action of gravity and the pushing force of the compression spring, the compression spring resets, and the pushing force of the compression spring makes the limiting part a insert into the new positioning hole 2b1 again, thereby locking the switching part 2b to be fixed and kept at the current position. Thus, the function switching between dust blowing and glue injection is realized. In the embodiment, the contact surface between the unlocking part e and the ball f is a slope, so as to facilitate the ball f to push the unlocking part e to slide backward.

[0038] Further, as shown in Figure 5 , the bottom end of the vertical assembly channel d is provided with a support ring table d1, and the middle part of the push rod 2c3 is provided with a support block h. In the unlocked state, the support block h can be fixed and supported on the support ring table d1, so as to ensure that the push rod 2c3 does not slide out of the lock 2c. In addition, in the unlocked state, there is a safety gap g between the uppermost ball f and the unlocking part e, which can avoid the ball f from pressing the unlocking part e when the operator accidentally touches the push rod 2c3, that is, prevent the limiting part a from exiting the current positioning hole 8b1, thereby improving the safety and stability of the whole device.

[0039] Please refer to Figure 1 , in the embodiment, the glue injection transmission part 1b is a worm, and the dust removal transmission part 1c is a cylindrical gear. Further refer to Figure 3 and 6 , the glue pushing assembly 4 includes a push plate 4a for pushing the adhesive bottle to inject glue, a rack 4b fixedly connected with the push plate 4a, a second gear 4c engaged with the rack 4b, and a worm wheel 4d coaxially fixed with the second gear 4c, wherein the worm wheel 4d is engaged with the worm. After the adhesive bottle is installed at the front end of the push plate 4a of the glue pushing assembly 4, the switching part 2b is pushed upward to keep the worm engaged with the worm wheel 4d, the motor 1 is started, the worm drives the worm wheel 4d to rotate, the worm wheel 4d drives the second gear 4c to rotate, thereby driving the rack 4b to slide, that is, the push plate 4a slides towards the adhesive bottle, at this time, the glue in the adhesive bottle is extruded from the glue nozzle, and the glue injection work of the glue pushing assembly 4 is completed.

[0040] Further refer to Figure 3 , the air blowing assembly 5 includes a fan cover 5a arranged on the lower side of the push plate 4a, and a fan blade 5b rotatably arranged in the fan cover 5a. The front end of the fan cover 5a is provided with an air outlet 5a1, the fan blade 5b is rotatable to make the airflow blow out from the air outlet 5a1, the fan blade 5b is rotatably installed in the fan cover 5a through a second output shaft 5c, and a third gear 5d engaged with the cylindrical gear is fixedly installed on the second output shaft 5c. AsFigure 8 As shown, the switch part 2b is pushed down, the cylindrical gear keeps meshing with the third gear 5d, the motor 1 is started, the cylindrical gear drives the third gear 5d to rotate, thereby driving the fan blade 5b to rotate, and the dust removal of the blowing assembly 5 is completed.
