The first feature is "under", "below" and "under" the second feature includes the first feature is directly below and obliquely below the second feature, or just indicates that the first feature is less than the second feature in horizontal height.

[0026] The technical scheme of the utility model is further illustrated below by specific embodiments in conjunction with the drawings.

[0027] As Figures 1-2 The utility model provides a wall bushing gouging tool for removing bushing structure embedded in concrete, which comprises a gouging rod 1. One end of the gouging rod 1 is a connecting end, and the other end is an operating end. The operating end is fixedly provided with a separating portion 11 and a cutting portion 12. The separating portion 11 is provided with a separating inclined surface 110. The cutting portion 12 is provided with a wall breaking blade 120. During the process of inserting the separating portion 11 between the bushing and the concrete, the separating inclined surface 110 can gradually approach and press against the outer wall segment of the bushing, and the wall breaking blade 120 can cut the outer wall segment pressed against the separating inclined surface 110.

[0028] When performing the bushing gouging operation, the worker can hold the gouging rod 1 and insert the separating portion 11 into the joint between the bushing and the concrete along the through direction of the bushing, so that the separating inclined surface 110 can gradually approach and press against the outer wall of the bushing, and the outer peripheral side of the bushing is separated from the concrete under the prying action of the separating portion 11. Further inserting the separating portion 11 makes the wall breaking blade 120 cut the side wall of the bushing along the through direction of the bushing until the bushing is completely cut open, thereby completing the gouging and removal of the bushing. The separating portion 11 and the cutting portion 12 cooperate with each other to separate the bushing from the concrete first, and then cut the bushing, which prevents the damage of the concrete, saves time and effort, has high operation efficiency, low production cost and strong universality.

[0029] It can be understood that if the sleeve is too tightly connected with the concrete, the resistance during the inserting process of the separating part 11 is large, and the connecting end of the chisel rod can be rotated during the inserting process of the separating part 11, the torque is increased by using the lever principle, so that the sleeve is separated from the concrete. 1 It should be noted that the sleeve is commonly used in the art PVC material.

[0030] It should be noted that the sleeve is commonly used in the art PVC material.

[0031] Specifically, the cutting part 12 is provided with two guide surfaces 121, and the two guide surfaces 121 are arranged at an angle to form a wall breaking edge 120. The arrangement of the guide surface 121 makes part of the debris cut by the wall breaking edge 120 slide out along the guide surface 121, preventing the debris from being stuck.

[0032] Specifically, the cutting part 12 is provided with two guide surfaces 121, and the two guide surfaces 121 are arranged at an angle to form a wall breaking edge 120. The arrangement of the guide surface 121 makes part of the debris cut by the wall breaking edge 120 slide out along the guide surface 121, preventing the debris from being stuck.

[0033] More specifically, the extension direction of the wall breaking edge 120 is perpendicular to the extension direction of the chisel rod 1, and the cutting direction of the wall breaking edge 120 is parallel to the extension direction of the chisel rod 1. The above arrangement prevents the wall breaking edge 120 from being damaged by excessive lateral shear force during cutting.

[0034] More specifically, the two guide surfaces 121 are communicated with the separating inclined surface 110. The above arrangement enables the wall breaking edge 120 to extend to the separating inclined surface 110, increases the contact area between the wall breaking edge 120 and the sleeve wall, and makes the wall breaking edge 120 applicable to sleeve structures of various thicknesses, and has higher universality.

[0035] Specifically, the two guide surfaces 121 are arranged symmetrically about the wall breaking edge 120 to ensure that the forces on both sides of the wall breaking edge 120 are balanced during cutting, and the durability is high, preventing the cutting edge from being damaged during cutting.

[0036] Specifically, the two guide surfaces 121 are arranged symmetrically about the wall breaking edge 120 to ensure that the forces on both sides of the wall breaking edge 120 are balanced during cutting, and the durability is high, preventing the cutting edge from being damaged during cutting.

[0037] Specifically, the edge of the separating inclined surface 110 away from the connecting end is provided with a separating edge 111. The arrangement of the separating edge 111 facilitates the smooth insertion of the separating part 11 between the concrete and the sleeve, and improves the convenience of operation.

[0038] More specifically, in the embodiment, the separation blade 111 is elliptical. The elliptical separation blade 111 can prevent local stress concentration of the separation blade 111 and prolong the service life of the separation blade 111.

[0039] Illustratively, in the embodiment, the radius of curvature of the separation blade 111 is 3 cm, so that the separation blade 111 can be smoothly connected with other positions of the edge of the separation slope 110. In other embodiments, the radius of curvature of the separation blade 111 can be determined according to the shape of the separation slope 110, which is not specifically limited herein.

[0040] Specifically, the wall bushing chisel tool further comprises a handle 2 which is screwed to the connecting end, and the handle 2 is provided with an anti-skid structure. The anti-skid structure can increase the contact friction between the handle 2 and the user's hand.

[0041] Illustratively, in the embodiment, the anti-skid structure is a rubber structure with rhombic anti-skid lines, and the depth of the anti-skid lines is 1 mm.

[0042] In other embodiments, the anti-skid structure can be an anti-skid pad such as a rubber pad, or the anti-skid structure can be an anti-skid protrusion which can be a point-shaped protrusion or a protrusion with any shape of lines, as long as it can increase the contact friction between the position and the worker's hand. The specific form can refer to the prior art, which is not specifically limited in the embodiment.

[0043] Illustratively, in the embodiment, the chisel rod 1 and the handle 2 are connected by M14x1.5 fine thread, the chisel rod 1 is made of No. 45 medium carbon steel threaded steel, and the handle 2 is an M14 internal threaded steel pipe.

[0044] Specifically, the chisel rod 1 is provided with multiple lengths. The above setting can facilitate the chisel rod 1 to adapt to different lengths of the sleeve structure and different thicknesses of the concrete, and has strong versatility.

[0045] Illustratively, in the embodiment, the chisel rod 1 is provided with three lengths of 18 cm, 22 cm and 32 cm to adapt to the concrete with a thickness of 15 cm-30 cm. In other embodiments, the length of the chisel rod 1 can be set according to the length of the sleeve and the thickness of the concrete, which is not specifically limited herein.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
