Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a caulking gun which is convenient to clean. Background Technique
[0002] Autoclaved aerated concrete block is a new type of building material with light weight, porous structure, good heat insulation and fire resistance, and can be nailed, sawed, planed and has a certain seismic capacity. After the construction of autoclaved aerated concrete blocks is completed, thin plastering construction treatment is required to ensure the smooth and beautiful surface of the building. Before the thin plastering construction, the base layer needs to be treated to make its surface smooth and firm for convenient construction. At this time, a caulking gun is needed to caulk the gaps of the base layer. The existing caulking gun replenishes and fills the caulking material by means of pulling and squeezing. However, during the filling process of the base layer, the material cannot be replenished, and the material replenishment work needs to be carried out again after the material in the caulking gun is used up. During this process, there is a long construction gap, which affects the caulking efficiency.
[0003] The Chinese utility model patent "A New Type of Automatic Caulking Gun" with the publication number of CN205400000U, the connection between the gun body and the barrel of the automatic caulking gun is a spiral structure. A funnel is installed above the barrel, and the connection between the bottom of the funnel and the barrel is a spiral structure, and a cover is provided at the top of the funnel. By adopting the above structure, compared with the traditional ordinary caulking gun, it can replace manual caulking construction. However, when the filler in the barrel solidifies or gets blocked, only the barrel can be discarded and replaced, causing great waste during the construction process. Content of the Utility Model

[0021] In order to make the content of the present utility model easier to understand, the technical solutions of the present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings. However, the present utility model is not limited thereto.
[0022] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: a caulking gun that is easy to clean, including a gun body 1 and a feeding component 2 connected to the gun body 1. The feeding component 2 includes a feeding rod 21 rotatably connected to the output end of the gun body 1. An outlet pipe 22 is sleeved outside the feeding rod 21. One end of the outlet pipe 22 is detachably connected to the gun body 1, and the other end of the outlet pipe 22 is used to extrude the filler. A locking component 3 is provided at one end of the gun body 1 close to the outlet pipe 22.
[0023] Combined with Figure 3 , a hopper 4 is fixedly provided at one end of the outlet pipe 22 close to the gun body 1. The hopper 4 is communicated with the outlet pipe 22. Under the action of the gravity of the filler, the filler in the outlet pipe 22 is extruded to ensure the continuous output of the filler.
[0024] As can be seen from the above description, by pressing the switch of the gun body 1, the motor in the gun body 1 drives the feeding rod 21 to rotate, so that the filler in the outlet pipe 22 flows out from the outlet of the outlet pipe 22 and is aligned with the base seam for caulking treatment. At the same time, during the caulking process, the hopper 4 can supplement the filler into the outlet pipe 22, so as to continuously carry out the caulking work.
[0025] As can be seen from the above description, through the detachable design of the outlet pipe 22, when the outlet pipe 22 is blocked or there is filler residue, there is no need to replace the new outlet pipe 22 and the feeding rod 21. Just disassemble the outlet pipe 22 and clean the outlet pipe 22 and the feeding rod 21, and then it can be reused.
[0026] As a further preference of this embodiment, a plurality of connecting rods 23 are arranged in an array around the connecting end of the discharge pipe 22, and a plurality of clamping grooves 24 corresponding to the connecting rods 23 are formed on the gun body 1. The gun body 1 and the discharge pipe 22 are connected through the connecting rods 23.
[0027] Please refer to Figure 4 , the locking assembly 3 includes a snap ring 31. A plurality of sliding grooves are formed in an array on the circumferential outer wall of the gun body 1. The sliding grooves communicate with the clamping grooves 24. A clamping block 34 is slidably arranged in each sliding groove. The outer side of the clamping block 34 is arranged as an inclined surface, and one side of the snap ring 31 close to the clamping block 34 is arranged as an annular inclined surface. By moving the snap ring 31, the annular inclined surface of the snap ring 31 squeezes the clamping block 34 inward.
[0028] As a further preference of this embodiment, fixing grooves 25 are formed on the connecting rods 23, and the clamping block 34 moves inward and is clamped with the connecting rod 23 through the fixing groove 25.
[0029] As a further preference of this embodiment, one end of the snap ring 31 is provided with an internal thread 32, and the circumferential outer wall of one end of the gun body 1 close to the discharge pipe 22 is provided with an external thread 33. The snap ring 31 is in threaded cooperation with the gun body 1. Through the threaded cooperation, the snap ring 31 can be locked to prevent the snap ring 31 from moving.
[0030] As can be seen from the above description, the snap ring 31 is in threaded cooperation with the gun body 1. By rotating the snap ring 31, the snap ring 31 can move back and forth on the gun body 1. When the annular inclined surface of the snap ring 31 moves to the position of the clamping block 34, the annular inclined surface of the snap ring 31 squeezes the inclined surface of the clamping block 34. As the snap ring 31 moves, the clamping block 34 gradually moves into the sliding groove, so that the inner side of the clamping block 34 is clamped into the fixing groove 25 on the connecting rod 23. When the clamping block 34 is completely clamped with the connecting rod 23, stop rotating the snap ring 31. At this time, the fixed connection of the discharge pipe 22 is completed.
[0031] As a further preference of this embodiment, sliding blocks 35 are fixedly arranged on both sides of the clamping block 34. Slide rods 36 are arranged in an annular array on the circumferential outer wall of the gun body 1. The slide rods 36 are fixedly arranged on the circumferential outer wall of the gun body 1. The slide rods 36 respectively penetrate through the corresponding sliding blocks 35, and a spring 37 is sleeved outside the slide rods 36. Both ends of the spring 37 are fixedly connected with the sliding block 35 and the gun body 1 respectively.
[0032] As can be seen from the above description, when the discharge pipe 22 needs to be disassembled, rotate the snap ring 31 in the reverse direction to make the snap ring 31 gradually move away from the clamping block 34. When the clamping block 34 completely disengages from the snap ring 31, the restriction on the clamping block 34 disappears. Under the reset action of the spring 37, the clamping block 34 is driven to move outward along the slide rod 36. When the clamping block 34 disengages from the fixing groove 25, the discharge pipe 22 can be disassembled.
[0033] The working principle of the present utility model:
[0034] When it is necessary to fill the joints of the base layer, the connecting rod 23 on one side of the discharge pipe 22 is snapped into the clamping groove 24. Immediately afterwards, the clamping ring 31 is rotated so that the clamping ring 31 moves back and forth on the gun body 1. When the annular inclined surface of the clamping ring 31 moves to the position of the clamping block 34, the annular inclined surface of the clamping ring 31 presses against the inclined surface of the clamping block 34. As the clamping ring 31 moves, the clamping block 34 gradually moves into the sliding groove, so that the inner side of the clamping block 34 is snapped into the fixing groove 25 on the connecting rod 23. When the clamping block 34 is completely clamped with the connecting rod 23, the rotation of the clamping ring 31 is stopped. At this time, the fixed connection of the discharge pipe 22 is completed. The discharge port of the discharge pipe 22 is aligned with the joint of the base layer, the switch of the gun body 1 is activated, and the feeding rod 21 is rotated to output the filler for joint filling.
[0035] When it is necessary to disassemble the discharge pipe 22 after the joint filling is completed, the clamping ring 31 is rotated in the reverse direction so that the clamping ring 31 gradually moves away from the clamping block 34. When the clamping block 34 is completely separated from the clamping ring 31, the restriction of the clamping block 34 disappears. Under the reset action of the spring 37, the clamping block 34 is driven to move outwards along the sliding rod 36. When the clamping block 34 is separated from the fixing groove 25, the discharge pipe 22 can be disassembled.
[0036] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
