Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, and more specifically to a small concrete hole plugging gun. Background Art

[0002] At present, in the construction of structures, tie rods are usually passed through the formwork to fix and reinforce the formwork. After the formwork is removed, through or semi-through holes will be left. In order to ensure the construction quality, it is generally necessary to seal the tie rod holes. The sealing is required to be dense and waterproof.

[0003] There are two main existing technologies: one is to use manual plugging of cement mortar, or manual plugging of precast concrete columns, and use a trowel to plug the cement mortar to seal the hole. This method wastes a lot of raw materials and mortar, takes a long time, requires a lot of manpower, and has a high cost.

[0004] The Chinese utility model patent application with application number 202022786824.X discloses a device for plugging the hole of an external wall tension screw rod, such as Figure 3 As shown, it includes a container, a tip, an injection device and a rear end cover, the container is a double-layer cylindrical structure that is hollow and open at both ends; the tip is a conical structure that is open at both ends, one end of which is a filler inlet end, and the other end is a filler outlet end, and the filler inlet end is detachably connected to one end of the container; the injection device includes a push rod and a piston that are fixedly connected, the piston includes a fixing plate and a rubber sheet, the rubber sheet is clamped between the two fixing plates, and the injection device is built into the cavity of the container; the rear end cover is a U-shaped structure, and a hole that matches the outer diameter of the container is provided at its sealing end, which can solve the problems of loose sealing of the screw hole in the manual plugging method, easy leakage of the exterior wall in the later stage, difficulty in hole plugging construction and operation, high labor consumption, and serious on-site pollution; the disadvantage of this method is that when plugging small-diameter holes or the mortar requires a slightly lower water content, it requires a lot of strength from workers and is inconvenient to use.

[0005] The Chinese utility model patent application with application number 202223307304.1 discloses a new type of glass glue packaging bottle, including: a bottle body, a glue nozzle, and a push tail plug arranged in the bottle body for promoting the extrusion of the glass glue; the glue nozzle includes a bottle body connecting part and a glue outlet part; one end of the glue outlet part is a glue outlet, and the other end is provided with an internal thread, which is threadedly connected to the connecting sleeve of the bottle body connecting part and can be detachably installed. Since the solidified part is concentrated at the outlet due to being exposed to air, it is only necessary to replace the outlet part close to the end of the nozzle. However, considering that cutting off part of the nozzle will enlarge the outlet, resulting in excessive extrusion of glass glue and serious waste, the nozzle of the utility model is provided with two sections, namely, a bottle body connecting part and a glue outlet part, which are disassembled and installed by threaded connection. When the glass glue is not used up and the glue outlet is solidified, it is only necessary to remove and replace the new glue outlet part for continued use. Moreover, the glue outlet part is provided with different shapes. Different functions can be realized by replacing the glue outlet part, which is convenient for multiple uses. However, the utility model only has a threaded connection between the bottle body connecting part and the glue outlet part, which is convenient for replacing the glue outlet part, but cannot meet the need for repeated filling of mud in this application.

[0006] Therefore, a small concrete hole sealing device is needed to ensure that project workers can complete the sealing work of each hole faster and easier, and the sealing quality is high, and the density and waterproofness are good. Utility Model Content

[0008] The mud tube comprises a barrel and a plugging nozzle; both ends of the barrel are open structures, one end is used to fill concrete mud and is connected to the plugging nozzle, and the other end is connected to the gun rack;

[0009] The gun frame includes a handle, a barrel groove, a return force device and a push rod;

[0010] The handle drives the push rod to move in the direction of the tube groove;

[0011] The pull-back device fixes the position of the push rod;

[0012] A rubber plug is provided at one end of the push rod close to the tube groove;

[0013] The rubber plug is movably connected to the mud tube.

[0014] In addition, a preferred structure is that the sealing nozzle includes a tube connecting portion and a slurry outlet nozzle; the tube connecting portion matches the cylinder structure; the slurry outlet nozzle is arranged at one end of the sealing nozzle away from the cylinder, and is an integral structure with the tube connecting portion.

[0040] In a specific embodiment of the utility model, an external thread is provided at one end where the cylinder 11 is connected to the sealing nozzle 12, and an internal thread is provided on the sealing nozzle, so as to avoid contamination of the thread when concrete slurry is filled into the cylinder 11, resulting in loose thread connection or inability to connect the cylinder 11 and the sealing nozzle 12.

[0041] In a specific embodiment of the present utility model, the slurry outlet nozzle 122 is a conical structure, so that the slurry is full when it is pushed out, effectively improving the plugging quality.

[0042] In a specific embodiment of the present invention, the size of the slurry nozzle 122 is slightly smaller than the size of the hole to be blocked, which facilitates the slurry nozzle 122 to be extended into the interior of the hole to be blocked, so that the concrete slurry fills the entire hole, improves the density of the blockage, and ensures the quality of the blockage.

[0043] The gun frame 2 includes a handle 21, a tube groove 22, a pull-back device 23 and a push rod 24; the handle 21 is movably connected to the pull-back device 23 to drive the push rod 24 to move in the direction of the tube groove 22; the tube groove 22 is used to set up and fix the mud tube 1, and the pull-back device 23 fixes the position of the push rod 24 so that the mud in the mud tube 1 can be discharged according to construction requirements; a rubber plug 25 is provided at one end of the push rod 24 close to the tube groove 22; the rubber plug 25 is fixedly connected to the push rod 24, and the rubber plug 25 is movably connected to the mud tube 1.
