Description

Technical Field

[0001] This utility model relates to the field of crack repair technology, and in particular to a portable automatic glue injection repair device for ground cracks. Background Technology

[0002] The portable automatic ground crack injection and repair device is a lightweight piece of equipment designed for the rapid repair of ground cracks. It is suitable for treating cracks in concrete pavements, factory floors, and indoor floors. The device integrates an automatic pressurized injection system and a precise crack positioning component, eliminating the need for complex external equipment. It can be transported and operated by a single person. During use, simply align the injection nozzle with the crack opening, and the device will automatically adjust the injection pressure and flow rate according to the crack width. Through the penetration and filling of a special high-strength repair adhesive, it achieves deep sealing of the crack, effectively preventing problems such as ground sanding and water seepage caused by crack expansion. The device body is made of wear-resistant and impact-resistant material and equipped with a high-capacity battery, significantly reducing the operational difficulty and time cost of traditional manual injection. It also ensures that the repaired ground meets strength standards and has a smooth appearance, combining high efficiency and reliability.

[0003] For different crack openings, the automatic glue injection repair device needs to replace the special nozzle for glue injection repair. Existing automatic glue injection repair devices use special glue or tape to fix the nozzle to the device to ensure its installation is firm. This fixing method has good sealing, but after using glue or tape, the nozzle can only be removed by external force and cannot be reused. Existing technology designs the nozzle with a structure with external or internal threads, and fixes it by rotating the nozzle to make it fit tightly with the pipeline. Although this method allows the nozzle to be disassembled and reused, the device needs to unscrew the bolts and tighten them again before each nozzle replacement. The process is time-consuming and labor-intensive, reducing the working efficiency of the device. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 , Figure 4 and Figure 5 The present invention provides an embodiment of a portable automatic glue injection repair device for ground cracks, including a body 1 and a nozzle 4. A quick-release mechanism 2 is fixedly connected to the left side of the outer wall of the body 1. The quick-release mechanism 2 is used to quickly install and remove the nozzle 4. A fixing mechanism 3 is fixedly connected to the left end of the outer wall of the body 1. The fixing mechanism 3 is used to improve the comfort of use.

[0032] The quick-release mechanism 2 includes a fixed ring 201, which is fixedly connected to the right side of the outer wall of the body 1. The fixed ring 201 has multiple first sliding grooves 202 in the middle. A rotating ring 203 is installed on the left side of the fixed ring 201. The rotating ring 203 has multiple second sliding grooves 204 in the middle. The left end of the inner wall of the fixed ring 201 is rotatably connected to the right end of the outer wall of the rotating ring 203. A drive assembly 205 is installed inside the rotating ring 203. A limiting assembly 206 is fixedly connected to the left side of the outer wall of the rotating ring 203.

[0033] The drive assembly 205 includes a plurality of rubber hinges 2051. A sliding post 2052 is fixedly connected to the left side of the outer wall of the rubber hinge 2051. The outer wall of the sliding post 2052 is slidably connected to the inside of the second sliding groove 204. A slider 2053 is fixedly connected to the right side of the outer wall of the rubber hinge 2051. The outer wall of the slider 2053 is slidably connected to the inside of the first sliding groove 202.

[0034] The limiting component 206 includes a ratchet 2061, which is fixedly connected to the left side of the outer wall of the rotating ring 203. A pawl bracket 2062 is installed on the top of the outer side of the ratchet 2061. A plurality of high carbon springs 2063 are fixedly connected to the right end of the outer wall of the pawl bracket 2062. The bottom of the outer wall of the high carbon springs 2063 is fixedly connected to the top of the outer wall of the fixed ring 201. A support plate 2064 is fixedly connected to the top of the outer wall of the fixed ring 201. The interior of the support plate 2064 is rotatably connected to the right end of the outer wall of the pawl bracket 2062.

[0035] Specifically, rotating the rotating ring 203 causes the second sliding groove 204 in its middle to push the internal sliding column 2052 to slide, causing the sliding column 2052 to drive the left rubber hinge 2051 to rotate. The slider 2053 on the right side of the rubber hinge 2051 can slide along the first sliding groove 202 in the middle of the fixed ring 201. Adjusting the opening angle of the rubber hinge 2051, the nozzle 4 is placed inside the rubber hinge 2051. Rotating the rotating ring 203 in the opposite direction causes the rubber hinge 2051 to clamp the nozzle 4. During the rotation, the ratchet 2061 on the left side of the rotating ring 203 rotates synchronously. The pawl holder 2062 engages with the ratchet 2061 under the action of the high carbon spring 2063, restricting the rotation of the rotating ring 203 from reversing. When the nozzle 4 needs to be disassembled, the pawl holder 2062 is moved to disengage from the ratchet 2061. Rotating the rotating ring 203 can then release the rubber hinge 2051, enabling quick disassembly and assembly of the nozzle 4 and improving the working efficiency of the device.

[0036] Reference Figure 3 , Figure 6 and Figure 7The fixing mechanism 3 includes a fixing ring 301, which is fixedly connected to the left end of the outer wall of the body 1. A fixing block 302 is fixedly connected to the front side of the outer wall of the fixing ring 301. A handle 303 is installed on the front side of the fixing block 302. A fixing half ring 304 is fixedly connected to the rear side of the outer wall of the handle 303. A movable half ring 305 is installed on the front side of the fixing half ring 304. The interior of the movable half ring 305 is slidably connected to the rear side of the outer wall of the handle 303. A locking component 306 is provided in the middle of the fixing block 302.

[0037] The engaging assembly 306 includes an engaging groove 3061, which is located in the middle of the fixing block 302. Multiple disc springs 3062 are fixedly connected inside the fixing block 302, and buckles 3063 are fixedly connected to adjacent sides of the outer walls of the multiple disc springs 3062.

[0038] Specifically, pushing the handle 303 causes the fixed half-ring 304 to slide into the engaging groove 3061. At this time, the fixed half-ring 304 pushes the buckle 3063 to compress the disc spring 3062. After the fixed half-ring 304 slides past the buckle 3063, the disc spring 3062 resets and compresses the buckle 3063, causing it to engage between the fixed half-ring 304 and the movable half-ring 305, thus fixing the handle 303. To remove the handle 303, simply continue pushing the handle 303 into the engaging groove 3061. The buckle 3063 is pushed again and compresses the disc spring 3062 repeatedly. When the movable half-ring 305 slides past the buckle 3063, it pulls the handle 303 outward. At this time, the movable half-ring 305 can use its curved surface to push the buckle 3063 again, quickly removing the handle 303 and improving user comfort.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A glue injection groove 6 is fixedly connected to the top of the outer wall of the body 1. A sealing plug 5 is slidably installed inside the glue injection groove 6. A switch 7 is installed at the top right end of the outer wall of the body 1. Multiple buttons 8 are installed at the right end of the switch 7. A handle 9 is installed at the bottom right end of the outer wall of the body 1. A base 10 is fixedly connected to the bottom of the outer wall of the handle 9.

[0040] Specifically, the top of the machine body 1 is provided with a glue injection tank 6, and the inside of the glue injection tank 6 is equipped with a sealing plug 5 to prevent the glue in the glue injection tank 6 from leaking and to prevent external impurities from entering the glue injection tank 6 and contaminating the glue. The right end of the machine body 1 is provided with a switch 7, which can control the operating status of the machine body 1 through multiple buttons 8. The handle 9 at the bottom of the machine body 1 provides a gripping part for the operator, making it easy for the operator to hold the device. The base 10 enhances the stability of the bottom of the handle 9 and prevents the handle 9 from shaking when gripped or subjected to force.

[0041] Working principle: Rotating the rotating ring 203 causes the second sliding groove 204 in its middle to push the internal sliding column 2052 to slide, causing the sliding column 2052 to drive the left rubber hinge 2051 to rotate. The slider 2053 on the right side of the rubber hinge 2051 can slide along the first sliding groove 202 in the middle of the fixed ring 201. Adjust the opening angle of the rubber hinge 2051, and place the nozzle 4 inside the rubber hinge 2051. Rotate the rotating ring 203 in the opposite direction to make the rubber hinge 2051 clamp the nozzle 4. During the rotation, the ratchet 2061 on the left side of the rotating ring 203 rotates synchronously. The pawl holder 2062 engages with the ratchet 2061 under the action of the high carbon spring 2063, restricting the rotation of the rotating ring 203 from reversing. When the nozzle 4 needs to be disassembled, move the pawl holder 2062 to disengage the pawl holder 2062 from the ratchet 2061. Rotating the rotating ring 203 will release the rubber hinge 2051, realizing the quick disassembly and assembly of the nozzle 4 and improving the working efficiency of the device.

[0042] Pushing the handle 303 causes the fixed half-ring 304 to slide into the engaging groove 3061. At this time, the fixed half-ring 304 pushes the buckle 3063 to compress the disc spring 3062. After the fixed half-ring 304 slides past the buckle 3063, the disc spring 3062 returns to its original position and compresses the buckle 3063, causing it to engage between the fixed half-ring 304 and the movable half-ring 305, thus fixing the handle 303. To remove the handle 303, simply continue pushing the handle 303 into the engaging groove 3061. The buckle 3063 is pushed again and compresses the disc spring 3062 repeatedly. When the movable half-ring 305 slides past the buckle 3063, it pulls the handle 303 outward. At this time, the movable half-ring 305 can use its curved surface to push the buckle 3063 again, allowing the handle 303 to be quickly removed, improving user comfort.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
