Description

Technical Field

[0001] This application relates to the field of installation tool technology, and in particular to an installation tool for drilling and nailing. Background Technology

[0002] Traditional expansion bolt installation relies on a step-by-step process of drilling followed by hammering. Users often need to alternate between using a hammer drill and a regular hammer, and additional manpower is required to secure the object being installed. This cumbersome and inefficient process is particularly evident at heights or in confined spaces. Furthermore, traditional installation methods struggle to simultaneously achieve drilling, suction, and effective hammering, resulting in bolt misalignment, bending, or insufficient hammering. Especially when working on ceilings overhead, it's difficult to accurately hammer the expansion bolt head vertically. The head-on hammering posture is ergonomically unsound, causing significant physical strain and increasing safety hazards.

[0003] Patent application CN202220036345.2 discloses a hammering rod based on a fastener, comprising a first connector that quickly attaches to an impact drill and a second connector that connects to a socket wrench. The lower end of the second connector is connected to a locking head, and the upper end of the second connector is connected to a second connecting rod. The lower end of the first connector is connected to a first connecting rod, and one or more extension rods connect the first and second connecting rods. In practice, this patent requires the use of an impact drill and a socket wrench for installation, making it inconvenient to use. Utility Model Content

[0004] This application is made in view of the above-mentioned problems, and its purpose is to provide an installation tool for drilling and nailing. The sleeve assembly allows the user to complete the hammering operation with only one hand holding the power tool when performing anchoring work, while the other hand can be used to support the object being installed, without the need for additional assistance, which greatly improves the feasibility and safety of high-altitude or single-person operations.

[0005] Specifically, the first aspect of this application provides an installation tool for drilling and nailing, including a limiting component, a sleeve component, and a hammering component. A first end of the limiting component is used to connect with the sleeve component, and a second end of the limiting component is used to connect with a fastener. The hammering component is sleeved inside the sleeve component, and the sleeve component is used to limit the hammering component. The hammering component can move forward relative to the sleeve component, thereby applying a hammering force to the fastener disposed within the limiting component.

[0006] Furthermore, the limiting component includes a limiting sleeve and a nut, the limiting sleeve and the nut being detachably connected, the limiting sleeve being disposed on the outside of the nut, and the nut having a hollow structure.

[0007] Furthermore, the limiting component also includes a limiting magnet, which is disposed inside the nut and has a hollow structure, used to attract the fastener and limit its position.

[0008] Furthermore, the hammering assembly includes a hammering rod, a first hammering sleeve, and a handle connected in sequence. The hammering rod is used to extend into the sleeve assembly, the first hammering sleeve is connected to the sleeve assembly, and the handle is used to connect to the electric hammer.

[0009] Furthermore, the hammering assembly includes a hammering rod, a second hammering sleeve, and a drill bit. The hammering rod is used to extend into the sleeve assembly, the second hammering sleeve has a hollow structure, and the drill bit can extend into the second hammering sleeve to achieve the hammering function.

[0010] Furthermore, the sleeve assembly includes a first sleeve and a second sleeve, a first end of the first sleeve is used to abut against the hammering assembly, a second end of the first sleeve is used to be sleeved on the outside of the second sleeve, a first end of the second sleeve is used to be detachably connected to a nut, and a second end of the second sleeve is used to be sleeved inside the first sleeve.

[0011] Furthermore, the sleeve assembly also includes a spring disposed inside the first sleeve and fitted onto the hammer rod.

[0012] Furthermore, the first end of the first sleeve is provided with a first limiting part whose inner diameter is smaller than that of the second end, and the inner diameter of the first limiting part is smaller than the outer diameter of the hammer sleeve.

[0013] Furthermore, the hammer rod is provided with a retaining spring groove and a C-shaped retaining spring, which limits the second end of the second sleeve.

[0014] Furthermore, the hammering rod can extend into the hollow structure of the nut to apply hammering force to the expansion screw.

[0015] This utility model has the following beneficial effects:

[0016] This invention connects fasteners through a limiting component and limits the hammering component to a sleeve component. The hammering component can move forward relative to the sleeve component, thereby applying hammering force to the fasteners set in the limiting component. This sleeve component allows users to complete the hammering operation with just one hand holding a power tool when performing anchoring work, while the other hand can be used to support the object being installed, without the need for additional assistance, greatly improving the feasibility and safety of high-altitude or single-person operations.

[0017] The nut in the limiting component of this application has a hollow structure and is equipped with a limiting magnet inside, which can firmly attract fasteners such as expansion nails to the head of the sleeve component, while leaving a channel for the hammer rod to pass through. During installation, the disc surface of the nail can be fixed and limited inside the cylinder, effectively preventing jumping or displacement caused by hammering, ensuring that the hammer rod can stably and accurately strike the head of the nail, and improving the anchoring quality and consistency.

[0025] Obviously, the following description is merely some examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios without any inventive effort. Furthermore, it is understood that although the effort involved in such development may be complex and lengthy, for those skilled in the art related to the content disclosed in this application, any changes to design, manufacturing, or production based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient disclosure of the content of this application.

[0026] See Figure 1 An installation tool for drilling and nailing includes a limiting component 10, a sleeve component 20, and a hammering component 30. The first end of the limiting component 10 is used to connect with the sleeve component 20, and the second end of the limiting component 10 is used to connect with a fastener. The hammering component 30 is sleeved inside the sleeve component 20, and the sleeve component 20 is used to limit the hammering component 30. The hammering component 30 can move forward relative to the sleeve component 20, thereby applying a hammering force to the fastener disposed within the limiting component 10.

[0027] This utility model connects fasteners via a limiting component 10, which can also be expansion bolts. A sleeve component 20 limits the hammering component 30, which can move forward relative to the sleeve component 20 to apply hammering force to the fasteners set in the limiting component 10. This sleeve component allows users to complete the hammering operation with just one hand holding a power tool while the other hand can be used to support the object being installed, without additional assistance, greatly improving the feasibility and safety of high-altitude or single-person operations. Example 1

[0028] See Figure 1 In this embodiment, the limiting component 10 includes a limiting sleeve 11 and a nut 12, which are detachably connected. The limiting sleeve 11 is disposed on the outside of the nut 12, and the nut 12 has a hollow structure. The limiting sleeve 11 is a hollow tubular body. One end of the limiting sleeve 11 has an internal thread 14 for connecting to the nut 12, and the other end of the limiting sleeve 11 has an inner hole slightly larger than the surface of the expansion nail disc. This inner hole serves to limit the surface of the expansion nail disc within the inner hole of the limiting sleeve 11 during hammering, preventing it from escaping the hammering range of the hammering rod 31 due to hammering vibrations. One end of the nut 12 has an internal thread for connecting with the external thread 15 of the second sleeve 22. The nut 12 has an external thread in the middle for connecting to the internal thread on the limiting sleeve 11. The other end of the nut 12 has a hollow cylindrical body for loading a hollow magnet.

[0029] In another preferred embodiment, the limiting component 10 further includes a limiting magnet 13, which is disposed inside the nut 12. The limiting magnet 13 has a hollow structure and is used to attract and limit the fastener. The magnet is an axially magnetized hollow circular magnet used to attract the disc surface of the expansion nail so that the expansion nail is tightly attracted to the head of the limiting component 10.

[0030] The nut 12 in the limiting component 10 of this application has a hollow structure and a limiting magnet 13 is provided inside it, which can firmly attract fasteners such as expansion nails to the head of the sleeve component, while leaving a channel for the hammer rod 31 to pass through. During the installation process, the disc surface of the nail can be fixed and limited inside the cylinder, effectively preventing jumping or displacement caused by hammering, ensuring that the hammer rod 31 can stably and accurately strike the head of the nail, and improving the anchoring quality and consistency.

[0031] See Figure 1 In this embodiment, the hammering assembly 30 includes a hammering rod 31, a first hammering sleeve 32, and a handle 33 connected in sequence. The hammering rod 31 is used to extend into the sleeve assembly 20. The first hammering sleeve 32 is connected to the sleeve assembly 20. The handle 33 is used to connect to the electric hammer. The hammering rod 31 is a solid cylinder. One end of the hammering rod 31 is provided with a handle that connects to the electric hammer. The handle can be a round four-hole type or a square handle, depending on the type of electric hammer. The other end of the hammering rod 31 is provided with a cylindrical hammering head 34, which is used to transmit the hammering force of the power tool to hammer the expansion nail into the installation wall surface. Near the handle end of the hammering rod 31, the first hammering sleeve 32 is provided to form a limiting step with a larger outer diameter. The outer diameter of the first hammering sleeve 32 is slightly larger than the inner diameter of the first limiting part 23 of the first sleeve 21, which is used to abut against the first sleeve 21 to prevent the first sleeve 21 from moving backward. Furthermore, the hammer rod 31 is provided with a retaining spring groove and a C-shaped retaining spring 35, which limits the second end of the second sleeve 22. During assembly, the first sleeve 21 is fitted onto the hammer rod 31, the spring 25 is inserted into the first sleeve 21, and then the second sleeve 22 is fitted into the first sleeve 21. After compressing the second sleeve 22 backward to expose the retaining spring groove, the C-shaped retaining spring 35 is installed. The tension of the spring 25 will push the second sleeve 22 forward until its limiting inner diameter touches the C-shaped retaining spring 35, at which point it can no longer move forward, thus forming a limiting function.

[0032] In this embodiment, the sleeve assembly 20 includes a first sleeve 21 and a second sleeve 22. The first end of the first sleeve 21 abuts against the hammering assembly 30, and the second end of the first sleeve 21 is sleeved onto the outside of the second sleeve 22. The first end of the second sleeve 22 is detachably connected to the nut 12, and the second end of the second sleeve 22 is fitted inside the first sleeve 21. The first sleeve 21 is a hollow tubular structure. The first end of the first sleeve 21 has a first limiting portion 23 with an inner diameter smaller than that of the second end. The inner diameter of the first limiting portion 23 is smaller than the outer diameter of the first hammering sleeve 32. The inner diameter of the other end of the first sleeve 21 is slightly larger than the outer diameter of the second sleeve 22. The first sleeve 21 is used to load the second sleeve 22 and the spring 25. The first end of the second sleeve 22 is detachably connected to the nut 12, preferably by a threaded connection or a snap-fit ​​connection. The second sleeve 22 is a hollow tubular structure. One end of the second sleeve 22 has a second limiting part 24 with an inner diameter slightly smaller than the outer diameter of the hammer rod 31 after the C-shaped retaining ring 35 is installed. The C-shaped retaining ring 35 limits the second sleeve 22, preventing it from moving further forward when it reaches the C-shaped retaining ring 35 of the first hammer sleeve 32. The other end of the second sleeve 22 has an external thread for connecting the nut 12.

[0033] In this embodiment, the sleeve assembly 20 further includes a spring 25, which is disposed inside the first sleeve and sleeved on the hammer rod 31. The spring 25 is sleeved on the hammer rod 31, with the first end of the spring 25 abutting against the first limiting part 23 of the first sleeve 21, and the second end of the spring 25 abutting against the second sleeve 22.

[0034] In this embodiment, the hammer head 34 of the hammering rod 31 can extend into the hollow structure of the nut 12 to apply hammering force to the expansion screw.

[0035] The usage method of this embodiment is as follows:

[0036] After drilling, remove the drill bit and replace it with a nail driver;

[0037] Insert the expansion nail or threaded nail into the limiting sleeve of the nail driver. The magnet inside the limiting sleeve will firmly attract the disc of the expansion nail to the end face of the nail driver.

[0038] Align the nailer with the expansion bolt inserted into the drilled hole, and start the hammer drill to push it into the hole. The first sleeve will retract as the expansion bolt penetrates deeper, while the spring force will also cause the limiting sleeve to move forward, keeping the disc of the expansion bolt inside the limiting sleeve. The hammering force of the hammer is transmitted through the hammering rod on the hammering sleeve, driving the expansion bolt into the installation hole, where it expands and anchors the object to the wall. During the forward push, the disc of the expansion bolt remains inside the limiting sleeve, allowing the hammering rod to accurately strike the head of the expansion bolt until it is fully embedded in the concrete wall before disengaging. Example 2

[0039] See Figure 2 and Figure 3 This embodiment is basically the same as Embodiment 1, except that the hammering assembly 30 has both drilling and hammering functions. Specifically, the hammering assembly 30 includes a hammering rod 31, a second hammering sleeve 36, and a drill bit 37. The hammering rod 31 is used to extend into the sleeve assembly 20. The second hammering sleeve 36 has a hollow structure, and the drill bit 37 can extend into the second hammering sleeve 36 to realize the hammering function.

[0040] This device is used for anchoring nail-type fasteners to concrete walls. The method of use is as follows:

[0041] Use a power tool with drill bit 37 to drill a hole in the wall;

[0042] The second hammer casing 36 is fitted onto the drill bit 37, and expansion bolts and other fasteners are installed in the limiting assembly 10.

[0043] A hollow magnet is used to attract the nail and guide it into the hole;

[0044] Start the tool to hammer and anchor the nail into the wall.

[0045] In this embodiment, the second hammer-driven sleeve and drill bit are detachable, which facilitates the conversion of the power tool from drilling mode to hammer-driven installation mode.

[0046] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
