Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy door and window installation tools, and particularly relates to a caulking device for installing aluminum alloy doors and windows. Background Technique

[0002] When installing aluminum alloy doors and windows, in order to ensure the waterproof performance between the aluminum alloy doors and windows and the building, a caulking device is often needed to caulk and seal the gap between the aluminum alloy doors and windows and the building. Generally, there are two types of caulking devices for installing aluminum alloy doors and windows: manual caulking guns and electric caulking guns; the electric caulking gun uses the power provided by the motor to drive the connecting rod to extrude the rubber tube through the transmission device, so that the glue flows out from the head of the rubber tube for caulking; compared with the manual caulking gun, the electric caulking gun has high efficiency and uniform glue output, and is widely used, such as the electric caulking gun with the publication number of CN209049665U.

[0003] In the above technical document, the output shaft of the motor directly drives the connecting rod to move by gears, and no torque increasing mechanism is provided. This results in that when the viscosity of the glue in the rubber tube is relatively high, the thrust of the connecting rod is small, resulting in insufficiently smooth glue output or even occasional glue breakage, resulting in poor caulking effect. Therefore, the existing technology requires a caulking device that can increase the extrusion force of the connecting rod. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a caulking device for installing aluminum alloy doors and windows to solve the technical problem that the thrust of the connecting rod is small in the above background technique, resulting in insufficiently smooth glue output or even occasional glue breakage, resulting in poor caulking effect.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A caulking device for installing aluminum alloy doors and windows includes: a frame, a rubber tube, and a switch frame; a rubber tube is fixed on the frame, the upper part of the rubber tube is designed with an open opening, and an opening is provided at one end of the rubber tube away from the frame to form a glue nozzle groove. A sliding sleeve is concentrically fixed at one end of the rubber tube close to the frame, and a rod-shaped push rod is slidably and internally fitted in the sliding sleeve. Tooth grooves are equally spaced on the top of the push rod; a torque increasing mechanism is provided on the frame. The main body of the torque increasing mechanism is a toothed ring plate integrally formed with the frame in a ring structure. A toothed ring is rotatably fitted at the center of the toothed ring plate by a bearing. The toothed ring meshes with the tooth grooves on the top of the push rod. A motor is fixed on the toothed ring plate through a motor bracket. A driving gear is concentrically fixed on the output shaft of the motor, and the driving gear directly or indirectly meshes with the toothed ring. A switch frame with a bracket structure is provided on the frame, a start switch is provided above the switch frame, and a battery compartment is also provided on the frame. The output end of the battery compartment is connected in series with the motor and the start switch by wires.

[0007] Further: In order to make the piston inside the rubber tube be more evenly stressed when the push rod pushes the rubber tube, a push plate in the structure of a metal disc is concentrically fixed at the end of the push rod far away from the motor.

[0008] Further: In order to further increase the force when the push rod pushes the rubber tube, a first torque-increasing gear with a number of teeth greater than that of the driving gear is rotationally matched with a shaft rod on the motor bracket. A second torque-increasing gear with a number of teeth less than that of the first torque-increasing gear is coaxially fixed on the shaft rod where the first torque-increasing gear is located. The second torque-increasing gear and the toothed ring are meshed with each other, and the first torque-increasing gear and the driving gear are meshed with each other.

[0009] Further: In order to enable the distance between the switch bracket and the frame to be adjusted according to the size of the user's palm so as to facilitate the user to press the start switch, the switch bracket is rotationally matched with the frame by a rotating shaft. A locking bolt is screwed and fixed at one end of the switch bracket close to the push rod in a threaded matching manner. Tightening the locking bolt can clamp and fix the switch bracket and the frame.

[0010] Further: In order to prevent residual glue from flowing out after the glue application is finished, a braking mechanism is further provided on the frame. The main body of the braking mechanism is a pressing piece rotationally matched at one end of the frame far away from the glue cylinder. A through rod hole for the push rod to penetrate is provided on the pressing piece. A tooth-shaped structure protruding downward is provided at the top of the through rod hole to form engaging teeth. A spring is provided between the pressing piece and the frame and is externally sleeved on the push rod. The spring has an elastic tendency to elongate. Normally, the through rod hole and the push rod do not contact each other.

[0011] The bottom of the battery compartment is detachably provided with a battery cover. At least four groups of lithium batteries are placed in the battery compartment. Connecting metal sheets are arranged in the battery compartment to connect the batteries in series therein, and then the electric energy is output outward through a wire to form an electric energy output end.

[0012] Further: In order to prevent the push rod from spinning in the sliding sleeve and causing tooth disengagement, a concave strip-shaped groove is formed along the axial direction of the lower surface of the push rod to form an anti-deviation groove. A convex strip engaged with the anti-deviation groove is arranged in the sliding sleeve. The convex strip limits the self-rotation of the push rod through the anti-deviation groove.

[0013] Further: In order to protect the motor and for the safety of the user, a plurality of threaded holes are formed on the disc to form cover holes. An increasing torque mechanism and the motor are covered by a cover shell, and the cover shell and the cover holes are screwed and fixed by bolts.

[0014] Further: In order to control the push rod to reset after the glue application is finished, the start switch is a two-stage push switch. One stage controls the forward rotation of the motor, and the other stage controls the reverse rotation of the motor.

[0015] In summary, the utility model has the following beneficial effects:

[0016] ①The caulking force of the push rod is increased, and the smoothness and stability of the glue extrusion can be ensured even when applying some adhesives with relatively high viscosity: through the establishment of a torque-increasing mechanism; the motor drives the driving gear to transmit the rotation to the first torque-increasing gear in a way of increasing torque, the first torque-increasing gear drives the coaxial second torque-increasing gear to rotate synchronously, the second torque-increasing gear transmits the rotation to the tooth ring in a way of increasing torque, and the tooth ring drives the push rod to move towards the glue nozzle groove side through the tooth grooves, and then the push plate at the end of the push rod will push the piston in the glue tube, and the glue in the glue tube is extruded from the glue nozzle to complete the electric caulking operation. In this way, the caulking force of the push rod is increased, and the stability of the glue extrusion can be ensured even when applying some adhesives with relatively high viscosity.

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment:

[0027] Please refer to Figures 1 - 7 , the present utility model provides a technical solution:

[0028] A caulking device for installing aluminum alloy doors and windows, comprising: a frame 1, a glue barrel 2, and a switch frame 3; a glue barrel 2 is fixed on the frame 1, the upper part of the glue barrel 2 is designed with an open opening, and an opening is provided at one end of the glue barrel 2 away from the frame 1 to form a glue nozzle groove 21. A sliding sleeve 12 is concentrically fixed at one end of the glue barrel 2 close to the frame 1. A push rod 5 with a rod-shaped structure is slidably and internally fitted in the sliding sleeve 12. Tooth grooves 51 are equidistantly arranged at the top of the push rod 5 (only part of the tooth grooves 51 are shown on the push rod 5 in the figure); an torque increasing mechanism 8 is provided on the frame 1. The main body of the torque increasing mechanism 8 is a toothed ring plate 81 integrally formed with the frame 1 in a ring structure. A toothed ring 85 is rotatably fitted at the center of the toothed ring plate 81 by a bearing 86. The toothed ring 85 meshes with the tooth grooves 51 at the top of the push rod 5. A motor 7 is fixed on the toothed ring plate 81 through a motor bracket 71. A driving gear 82 is concentrically fixed on the output shaft of the motor 7. The driving gear 82 directly or indirectly meshes with the toothed ring 85. A switch frame 3 with a bracket structure is provided on the frame 1. A start switch 4 is provided above the switch frame 3. A battery compartment 10 is also provided on the frame 1. The output end of the battery compartment 10 is connected in series with the motor 7 and the start switch 4 by wires.

[0029] In order to make the force on the piston inside the rubber tube 13 more uniform when the push rod 5 pushes the rubber tube 13, a push plate 6 with a metal disc structure is concentrically fixed at the end of the push rod 5 away from the motor 7.

[0030] In order to further increase the force when the push rod 5 pushes the rubber tube 13, a first torque increasing gear 83 with a number of teeth greater than that of the driving gear 82 is rotatably fitted on the motor bracket 71 by a shaft rod. A second torque increasing gear 84 with a number of teeth less than that of the first torque increasing gear 83 is coaxially fixed on the shaft rod where the first torque increasing gear 83 is located. The second torque increasing gear 84 meshes with the toothed ring 85, and the first torque increasing gear 83 meshes with the driving gear 82.

[0031] In order to adjust the distance between the switch frame 3 and the frame 1 according to the size of the user's palm to facilitate the user to press the start switch 4, the switch frame 3 is rotatably fitted with the frame 1 by a rotating shaft 31. A locking bolt 32 is screwed and fixed at one end of the switch frame 3 close to the push rod 5. Tightening the locking bolt 32 can clamp and fix the switch frame 3 and the frame 1.

[0032] In order to prevent residual glue from flowing out after glue application is completed, a braking mechanism 9 is further provided on the frame 1. The main body of the braking mechanism 9 is a pressing piece 91 rotatably fitted at one end of the frame 1 away from the glue cylinder 2. A through-hole 93 for the push rod 5 to penetrate is provided on the pressing piece 91. A tooth-shaped structure protruding downward is provided at the top of the through-hole 93 to form an engaging tooth 94. A spring 92 is provided between the pressing piece 91 and the frame 1 and is externally fitted on the push rod 5. The spring 92 has a tendency to stretch elastically. Under normal conditions, the through-hole 93 and the push rod do not contact each other.

[0033] The bottom of the battery compartment 10 is detachably provided with a battery cover 11. At least four groups of 18650 lithium batteries are placed in the battery compartment 10. Connecting metal sheets are arranged in the battery compartment 10 to connect the batteries in series therein, and then the electrical energy is output externally through wires to form an electrical energy output terminal.

[0034] In order to prevent the push rod 5 from spinning in the sliding sleeve 12 and causing tooth disengagement, a concave strip-shaped groove is provided on the lower surface of the push rod 5 along its axial direction to form an anti-deviation groove 52. A convex strip that engages with the anti-deviation groove 52 is provided in the sliding sleeve 12. The convex strip limits the spinning of the push rod 5 through the anti-deviation groove 52.

[0035] In order to protect the motor 7 and for the safety of the user, a number of threaded holes are provided on the disc 81 to form cover holes 87. An increasing-torque mechanism 8 and the motor 7 are covered with a cover shell, and the cover shell is screwed and fixed to the cover holes 87 through bolts (in the figure, the cover shell is not shown for the convenience of displaying the internal structure).

[0036] In order to control the push rod 5 to reset after glue application is completed, the start switch 4 is a two-position push switch. One position controls the forward rotation of the motor 7, and the other position controls the reverse rotation of the motor 7.

[0037] Brief description of the usage process:

[0038] In use, place an 18650 lithium battery in the battery compartment, close the battery cover 11, place a new rubber tube 13 (the rubber tube 13 is a finished product of standard size purchased, and its specific structure is not within the protection scope of this application, so its specific structure is omitted) into the rubber cylinder 2. The piston end of the rubber tube 13 places the push plate 6, and the nozzle 14 of the rubber tube 13 is snapped into the nozzle groove 21. When caulking is required, press the start switch 4. The start switch 4 connects the forward rotation circuit between the battery compartment and the motor 7 (the forward rotation circuit is the circuit for controlling the caulking of the push rod 5, and the reverse rotation circuit is the circuit for controlling the reset of the push rod 5). The motor 7 transmits the rotation to the first torque-increasing gear 83 in a way of increasing torque through the driving gear 82. The first torque-increasing gear 83 drives the second torque-increasing gear 84 coaxial with it to rotate synchronously. The second torque-increasing gear 84 transmits the rotation to the gear ring 85 in a way of increasing torque. The gear ring 85 drives the push rod 5 to move towards the nozzle groove 21 side through the tooth groove 51. Then, the push plate 6 at the end of the push rod 5 will push the piston in the rubber tube 13, and the glue in the rubber tube 13 is extruded from the nozzle 14, completing the electric caulking operation.

[0039] When the caulking is finished, in order to avoid residual glue due to inertia, the pressing piece 91 in the braking mechanism 9 can be pressed once when the caulking is paused. Under the lever action of the pressing piece 91, the engaging tooth 94 above the through rod hole 93 is embedded into the tooth groove 51, and the push rod 5 will be limited by the engaging tooth 94. If the push rod 5 still has inertial movement, it will drive the pressing piece 91 to deflect through the engaging tooth 94. The pressing piece 91 will squeeze the spring 92, and the elastic force of the spring 92 will prevent the inertial movement of the push rod 5 and push the push rod 5 in the reverse direction, causing it to retreat a certain distance and avoiding its continuous extrusion of the piston in the rubber tube 13.

[0040] When the glue in the rubber tube 13 is used up, a new rubber tube 13 needs to be replaced; during replacement, the reverse rotation circuit between the battery compartment and the motor 7 is connected through the start switch 4 (the forward rotation circuit is the circuit for controlling the caulking of the push rod 5, and the reverse rotation circuit is the circuit for controlling the reset of the push rod 5). Through the above principle, the motor 7 drives the push rod 5 to reset through transmission. After the reset is completed, the used-up rubber tube 13 can be removed and a new rubber tube 13 can be replaced (the start switch 4 uses a conventional forward and reverse switch, which is a direct application of this application and is within the protection scope of this application, so its specific structure and working principle are omitted).

[0041] The locking bolt 32 can be loosened, and the switch frame 3 is rotated around the rotation axis 31 so that the distance between the frame 1 and the switch frame 3 is adapted to the size of the user's palm, so as to facilitate the user to press the start switch 4. After the adaptation is completed, locking the locking bolt 3 can clamp and fix the switch frame 3 and the frame 1.

[0042] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation to the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
