Description

Technical Field

[0001] This utility model relates to the field of wall sleeve dismantling tools, and in particular to a wall sleeve chisel tool. Background Technology

[0002] A through-wall sleeve is a type of support formwork. If the building wall needs to have pre-drilled installation holes, after the building wall is poured, the through-wall sleeve is quickly inserted through the building wall. After the building wall has cured, the through-wall sleeve is chiseled out of the building wall to form the required installation holes on the building wall.

[0003] However, the wall sleeves in the relevant technologies lack the necessary chisel tools, making it inconvenient for workers to chisel them and easily damaging the building walls, which needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tool for chiseling through wall sleeves, which can facilitate workers to chisel through wall sleeves, improve work efficiency, and reduce the risk of wall damage.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wall sleeve chisel tool, including a vertically arranged handle, a support cylinder is horizontally fixedly connected to the top of the handle, a hammer rod is slidably inserted inside the support cylinder, a hammer head for hammering is fixedly connected to one end of the hammer rod, and a limiting part for abutting the end face of the wall sleeve is provided at the other end, and a limiting ring is fixedly connected to one end of the support cylinder near the limiting part, and the limiting ring can abut against the building wall.

[0006] Optionally: The limiting part includes a limiting disc and a limiting frustum. The limiting disc is coaxially disposed at the end of the hammer rod away from the hammer head. The limiting frustum is coaxially fixed at the end of the limiting disc away from the hammer rod. The limiting frustum can be tightly inserted into the through-wall sleeve. The outer diameter of the limiting disc is smaller than the outer diameter of the through-wall sleeve and larger than the outer diameter of the hammer rod. The limiting disc is used to abut against the end face of the through-wall sleeve.

[0007] Optionally, the limiting disc is detachably connected to the hammer rod.

[0008] Optionally: a locking post is coaxially fixedly connected to one end of the limiting disc away from the limiting frustum, and a locking groove is provided at one end of the hammer rod away from the hammer head, and the locking post is threadedly connected to the locking groove.

[0009] Optionally, an elastic protective ring is fixedly connected to the side of the limiting ring near the limiting part, and the protective ring can abut against the building wall.

[0010] Optionally, the lower end of the handle is fitted with an elastic anti-slip sleeve.

[0011] Optionally, a suspension ring is fixedly connected to the bottom of the anti-slip sleeve.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This chisel tool can be used with through-wall sleeves to facilitate quick chiseling of these sleeves, improving work efficiency and reducing the risk of wall damage. Furthermore, because the limiting part is detachable, workers can replace it with one that matches the size of the through-wall sleeve, ensuring smooth chiseling operations for sleeves of different sizes and thus improving usability.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 , Figure 2 A wall sleeve chisel tool includes a vertically arranged handle 1, the bottom of which is for the worker to grip, and a support cylinder 2 horizontally fixedly connected to the top of the handle 1. A hammer rod 3 is slidably inserted inside the support cylinder 2. One end of the hammer rod 3 is fixedly connected to a hammer head 4 for hammering, and the other end is provided with a limiting part 5 for abutting against the end face of the wall sleeve. At the same time, a limiting ring 6 is fixedly connected to the end of the support cylinder 2 near the limiting part 5, and the limiting ring 6 can abut against the building wall.

[0020] The limiting part 5 is placed against the end face of the through-wall sleeve, and then the hammer head 4 is struck with a hammer. At this time, the striking force is applied to the end of the through-wall sleeve through the limiting part 5, so that the through-wall sleeve is chiseled out of the building wall. This chiseling tool can be used with the through-wall sleeve to facilitate workers to quickly chisel out the through-wall sleeve, thereby improving work efficiency.

[0021] Furthermore, during the hammering of the hammer head 4, the limiting ring 6 can abut against the building wall, providing a good limiting effect and reducing the risk of shaking of components such as the handle 1, so as to ensure that the hammer rod 3 can move smoothly along the axis of the through-wall sleeve, so that the through-wall sleeve can be successfully chiseled out.

[0022] Reference Figure 2 , Figure 3 The limiting part 5 includes a limiting disc 51 and a limiting frustum 52. The limiting disc 51 is coaxially disposed at the end of the hammer rod 3 away from the hammer head 4, and the limiting frustum 52 is coaxially fixed at the end of the limiting disc 51 away from the hammer rod 3, and the limiting frustum 52 can be tightly inserted into the through-wall sleeve. The outer diameter of the limiting disc 51 is smaller than the outer diameter of the through-wall sleeve and larger than the outer diameter of the hammer rod 3, and the limiting disc 51 is used to abut against the end face of the through-wall sleeve.

[0023] The limiting frustum 52 is tightly inserted into the through-wall sleeve until the limiting disc 51 abuts against the end face of the through-wall sleeve. Then, the hammer head 4 is struck with a hammer until the through-wall sleeve is chiseled out of the building wall. Because the outer diameter of the limiting disc 51 is smaller than the outer diameter of the through-wall sleeve but larger than the outer diameter of the hammer rod 3, it prevents the limiting disc 51 from scratching the installation hole formed in the building wall. At the same time, the hammer rod 3 can extend into the installation hole to ensure the ejection distance of the through-wall sleeve, thereby improving the chiseling effect.

[0024] Reference Figure 2 , Figure 3 The limiting disc 51 is detachably connected to the hammer rod 3. The operator can replace the limiting part 5 with one that matches the size of the through-wall sleeve to ensure the smooth progress of chiseling operations for through-wall sleeves of different sizes, thereby improving the adaptability of use.

[0025] Reference Figure 2 , Figure 3 The end of the limiting disc 51 away from the limiting platform 52 is coaxially fixedly connected to a locking post 7, and the end of the hammer rod 3 away from the hammer head 4 is provided with a locking groove 8, and the locking post 7 is threadedly connected to the locking groove 8, so that the limiting disc 51 and the hammer rod 3 can be quickly disassembled and assembled, thereby improving the work efficiency when replacing the limiting part 5.

[0026] Reference Figure 2 , Figure 3 A flexible protective ring 9 is fixedly connected to the side of the limiting ring 6 near the limiting part 5, and the protective ring 9 can abut against the building wall to protect the building wall and reduce the risk of damage to the building wall.

[0027] Reference Figure 1 , Figure 2The lower end of the handle 1 is fixedly fitted with an elastic anti-slip sleeve 10 to improve the anti-slip effect and make it easier for workers to grip the handle 1. At the same time, a hanging ring 11 is fixedly connected to the bottom of the anti-slip sleeve 10 to facilitate the hanging and storage of chisel tools by workers.

[0028] In this embodiment, the protective ring 9 and the anti-slip sleeve 10 are made of elastic materials such as rubber, silicone or latex, while the handle part 1, support cylinder 2, hammer rod 3, hammer head 4 and limiting part 5 are made of steel to improve the service life of the chisel tool.

[0029] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
