Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a construction drilling and filling auxiliary sleeve, which solves the problem of poor connection stability between the expansion screw and the wall due to the unstable support and frictional resistance inside the drilling due to different wall strengths. , The traditional expansion screw cannot be perfectly matched with the drilled hole, it needs to be rammed into the drilled hole, and the tamping force will also destroy the support between the expansion screw and the wall

Embodiment 1

[0037] Such as Figure 1-5As shown, the present invention provides a technical solution: a construction drilling and filling auxiliary sleeve, including a hole wall limiting splint 1, and the middle position of the two hole wall limiting splints 1 is provided with an adjustment through groove 2, and the adjustment through groove 2 The interiors of the holes are all penetrated and slidably connected with an adjustment extension rod 3, and the two hole wall limiting splints 1 are combined to form a ring shape, and the bottom surface of the hole wall limiting splint 1 is evenly spaced and fixedly connected with inner fitting clips 4, and the inner fitting clips 4 are connected. The clips 4 are arranged inclined toward the inner side, and the inner fitting clips 4 are combined to form a circular truncated shape. The middle position near the bottom of the internal test is fixedly connected with the travel track 6, the inner sliding connection of the travel track 6 is connected with...

Embodiment 2

[0039] Such as Figure 1-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a construction drilling and filling auxiliary sleeve, the inner fitting clip 4 is in the middle position of the internal measurement and is located above the travel track 6 and is connected with a rotating Block 12, one end of the outer side of the rotating block 12 is fixedly connected with a spring pressing rod 13, and the top of the rotating block 12 is fixedly connected with a supporting push rod 14, and the spring pressing rod 13 and the supporting pushing rod 14 are vertically arranged. Reduce the initial entry resistance of the expansion screw and reduce the difficulty of installation of the expansion screw.

[0040] One end of the spring pressing rod 13 away from the rotating block 12 is rotatably connected with a guide roller 15 .

[0041] A stabilizing needle plate 16 is fixedly connected to the end of the supporting push rod 14 away from the rotat...

Embodiment 3

[0043] Such as Figure 6-7 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a kind of building drilling and filling auxiliary sleeve, the feeding stabilization mechanism 8 includes a deformation fitting plate 81, the bottom of the deformation fitting plate 81 and The limiting slider mechanism 7 is fixedly connected, and the top of the deformable fitting plate 81 is fixedly connected with a support pressing plate 82 , and the inner side of the top of the supporting pressing plate 82 is in contact with the surface of the inner fitting clip 4 . There is an elastic force between the deformation fitting plate 81 and the support plate 82, which can increase the frictional resistance between the expansion screw and the auxiliary sleeve, and ensure the stability of the expansion screw installation.

[0044] The middle positions of the supporting platen 82 are respectively provided with restricting opening grooves 83 , and th...

Abstract

The invention discloses a building drilling and filling auxiliary sleeve which comprises hole wall limiting clamping plates. Adjusting through grooves are formed in the middles of the interiors of thetwo hole wall limiting clamping plates, adjusting extension rods penetrate through the interiors of the adjusting through grooves and are slidably connected with the interiors of the adjusting through grooves, and inner attaching clamping pieces are evenly and fixedly connected to the surfaces of the bottoms of the hole wall limiting clamping plates at equal intervals. The inner attaching clamping pieces are combined to form a circular truncated cone shape, stable limiting needles are fixedly connected to the vertical positions of the outer side surfaces of the inner attaching clamping piecesat equal intervals, stroke rails are fixedly connected to the middle positions, close to the lower portion, of the inner sides of the inner attaching clamping pieces, and limiting sliding block mechanisms are slidably connected into the stroke rails. Feeding stabilizing mechanisms are fixedly connected to the positions, close to the inner sides, of the tops of the limiting sliding block mechanisms, and tamping baffles are fixedly connected to the top ends of the exteriors of movable sliding blocks. The invention relates to the technical field of building. According to the building drilling and filling auxiliary sleeve, the connection stability between the auxiliary sleeve and a wall body is improved when an expansion screw enters the auxiliary sleeve.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction drilling and filling auxiliary sleeve. Background technique [0002] Construction refers to the assets made by man-made construction, which belongs to the category of fixed assets, including two categories: houses and structures. Housing refers to engineering buildings for people to live, work, study, produce, operate, entertain, store items and carry out other social activities. What is different from buildings are structures, which refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges, and chimneys. [0003] For example, the Chinese invention publication number is: a kind of drilling safety protector of CN106624057A, comprising a dust cover and a pressing device that can be placed on the drill rod and can press the dust cover tightly on the drilling base surface; the dust cover includes a cover ...
