Description

Technical Field

[0001] This application relates to the field of building construction tools, and more particularly to a hammer for building construction. Background Technology

[0002] A hammer is a common tool on construction sites. Workers use hammers for continuous work; however, because the hammer's structure is relatively fixed, repeatedly striking surfaces of different sizes and materials can easily damage parts of the work surface, leading to rework, economic losses, and even safety hazards. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a hammer for building construction to solve the problem that when a hammer is used to continuously strike surfaces of different areas, it is easy to damage parts of the working surface.

[0004] This application provides a hammer for building construction, including a hammer head and an auxiliary rod. The striking surface of the hammer head has an opening, which penetrates the hammer head along a direction perpendicular to its plane to form a channel. The channel has a sliding section and a threaded section in sequence along its extension direction.

[0005] The auxiliary rod includes a striking end, a rod body, and an operating end arranged sequentially along its own axis. After the auxiliary rod extends into the channel, a portion of the rod body is threadedly connected to the threaded section. At least a portion of the operating end is always located outside the channel, and the operating end moves the striking end through the rod body.

[0006] In the first state, the striking end is located within the channel; in the second state, the striking end extends out of the channel through the opening.

[0007] Based on the aforementioned hammer for building construction, when workers are striking larger work surfaces, they can directly use the hammer head to strike; when striking smaller work surfaces, workers only need to rotate the operating end, and the rod moves within the channel, thereby causing the striking end to extend out of the channel. In this case, workers can use the striking end with a smaller contact area to strike, thus greatly reducing the possibility of the hammer damaging smaller work surfaces, avoiding economic losses and safety hazards. Furthermore, workers do not need to carry multiple hammers; carrying only one hammer is sufficient to meet the needs of different work surfaces.

[0008] In one embodiment of the hammer described above, the channel is provided with a receiving space extending inward from the opening, the receiving space being used to receive the striking end, and the orthographic projection of the receiving space along its extending direction gradually decreases.

[0009] In one of the hammer's embodiments, the hitting end is detachably connected with the rod body, and the hitting surface of the hitting end is leveled with the hitting surface of the hammer head by rotating the operating end.

[0010] In one of the hammer's embodiments, the auxiliary rod is provided with a containing cavity, and elastic balls are distributed in the containing cavity. The auxiliary rod is provided with a through hole on the side close to the hitting end, and the through hole is in communication with the containing cavity.

[0011] In one of the hammer's embodiments, the auxiliary rod is further provided with an elastic member, and the containing cavity is slidably arranged in the auxiliary rod and connected with the auxiliary rod by the elastic member.

[0012] In one of the hammer's embodiments, the opening is detachably provided with a cover for sealing the opening, and in the first state, the side of the cover away from the operating end is leveled with the hitting surface of the hammer head.

[0013] In one of the hammer's embodiments, the hammer further comprises a handle, and the handle comprises a first segment and a second segment. The first end of the first segment is provided with an inwardly extending connecting channel, and the second segment is provided with a connecting rod threadedly connected with the connecting channel.

[0014] In one of the hammer's embodiments, the connecting rod comprises a main body segment and a bent segment rotationally connected with the main body segment. After the main body segment is moved out of the connecting channel at the rotationally connected position of the main body segment and the bent segment, the bent segment is rotated to form a preset included angle between the bent segment and the main body segment.

[0015] In one of the hammer's embodiments, the side wall of the first segment is provided with a groove, and the side wall of the second segment is provided with an abutting portion. After the preset included angle is formed between the bent segment and the main body segment, the abutting portion is clamped in the groove.

[0016] In one of the hammer's embodiments, the operating end further comprises a prying portion, and the prying portion is provided with a clamping groove for clamping a screw rod portion.

[0017] The one or more embodiments of the hammer have at least one or more of the following beneficial effects:

[0018] When the worker strikes a large work surface, the worker directly uses the hammer head to strike; when the worker strikes a small work surface, the worker only needs to rotate the operating end, and the rod body moves in the channel, thereby driving the hitting end to extend out of the channel. At this time, the worker can use the hitting end with a smaller contact area to strike, thereby greatly reducing the possibility of the hammer damaging the small work surface, avoiding economic losses and safety hazards, and the worker does not need to carry multiple hammers, but only needs to carry one hammer to meet the needs of different work surfaces.

DETAILED DESCRIPTION

[0027] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0028] As described in the background, since the structure of the hammer is relatively fixed, when the hammer is used to continuously strike different areas and material surfaces, part of the work surface is easily damaged, thereby causing economic losses and even safety hazards.

[0029] Therefore, the hammer for house building is creatively provided in the application, which comprises a hammer head and an auxiliary rod. When a worker strikes a larger work surface, the worker directly uses the hammer head to strike; when the worker strikes a smaller work surface, the worker only needs to rotate the operation end, and the rod body moves in the channel, thereby driving the striking end to extend out of the channel. At this time, the worker can use the striking end with a smaller contact area to strike, thereby greatly reducing the possibility of the hammer damaging the smaller work surface, avoiding economic losses and safety hazards, and the worker does not need to carry multiple hammers, but only needs to carry one hammer to meet the needs of different work surfaces.

[0030] The application will be specifically described below through specific examples.

[0031] Referring to Figures 1 to 4 The application provides a hammer for house building, which comprises a hammer head 1 and an auxiliary rod 2. The striking surface of the hammer head 1 is provided with an opening 11, the opening 11 penetrates the hammer head 1 along a direction perpendicular to the plane where the opening 11 is located to form a channel 12, and the channel 12 is sequentially provided with a sliding section 121 and a threaded section 122 along the extension direction of the channel 12. The auxiliary rod 2 comprises a striking end 21, a rod body 22 and an operation end 23 which are sequentially arranged along the axial direction of the auxiliary rod 2. After the auxiliary rod 2 extends into the channel 12, a part of the rod body 22 is threadedly connected with the threaded section 122, at least a part of the operation end 23 is always located outside the channel 12, and the operation end 23 moves the striking end 21 through the rod body 22. In a first state, the striking end 21 is located in the channel 12. In a second state, the striking end 21 extends out of the channel 12 through the opening 11.

[0032] It can be understood that the hammer generally further comprises a hammer handle 3, so that a worker holds the hammer to complete the striking work.

[0033] In some embodiments, the shape of the hammer head 1 can be a regular shape such as a cylindrical shape, a conical shape, a triangular prism or a quadrangular prism, or can even be an irregular shape, as long as the requirement of smoothly striking a work surface is met.

[0034] In addition, it should be noted that in the second state, the distance by which the striking end 21 extends out of the channel 12 is not always constant, and the distance between the striking end 21 and the opening 11 after the striking end 21 extends out of the channel 12 can be flexibly adjusted according to the specific conditions of the work surface on site.

[0035] Specifically, when the worker strikes a larger work surface, the worker directly uses the hammer head 1 to strike; when the worker strikes a smaller work surface, the worker only needs to rotate the operation end 23, and the rod body 22 moves in the channel 12, thereby driving the striking end 21 to extend out of the channel 12. At this time, the worker can use the striking end 21 with a smaller contact area to strike, thereby greatly reducing the possibility of the hammer damaging the smaller work surface, avoiding economic losses and safety hazards, and the worker does not need to carry multiple hammers, but only needs to carry one hammer to meet the needs of different work surfaces.

[0036] It can be understood that the rotation direction of the operation end 23 depends on the thread direction of the threaded section 122.

[0037] In some examples, as shown in Figure 2 and Figure 3 , the channel 12 is provided with an accommodation space 123 extending inward from the opening 11, the accommodation space 123 is used to accommodate the striking end 21, and the orthographic projection of the accommodation space 123 along its extension direction gradually decreases.

[0038] It can be understood that the shape of the accommodation space 123 can be any shape that meets the above conditions. In the embodiment, in order to facilitate processing, the shape of the accommodation space 123 is a circular truncated cone shape.

[0039] Specifically, by setting the circular truncated cone-shaped accommodation space 123, the accommodation space 123 is convenient for accommodating striking ends 21 of different specifications, and the maximum striking surface of the striking end 21 is the cross-sectional dimension of the opening 11.

[0040] In some embodiments, as shown in Figure 3 , the striking end 21 is detachably connected with the rod body 22, and by rotating the operation end 23, the striking surface of the striking end 21 is flush with the striking surface of the hammer head 1. When striking two or more work surfaces with a significant difference in area, by replacing the striking end 21 with a striking surface of different sizes, the adaptability of the hammer can be further improved.

[0041] The detachable connection between the striking end 21 and the rod body 22 includes threaded connection, plug-in connection, or clamping connection, etc. In the embodiment, the striking end 21 is threadedly connected with the rod body 22.

[0042] In some embodiments, as shown in Figure 3 , the accessory rod 2 is provided with an accommodation cavity 24, the accommodation cavity 24 is distributed with elastic balls 241, and the side of the accessory rod 2 facing the striking end 21 has a through hole 25 communicating with the accommodation cavity 24.

[0043] It can be understood that, in order to facilitate the movement of the elastic balls 241, thereby ensuring the cushioning effect when the hitting end 21 strikes, the total volume of all the elastic balls 241 occupies 1 / 3 to 2 / 3 of the total volume of the accommodating cavity 24. In the embodiment, the elastic balls 241 are made of rubber.

[0044] Specifically, when the hitting end 21 is used to strike the work surface, the reaction force of the work surface is transmitted into the accommodating cavity 24, the elastic balls 241 move accordingly, and a part of the vibration force is unloaded, so that the hitting end 21 can strike the work surface smoothly without large shaking.

[0045] Further, in some embodiments, the auxiliary rod 2 is further provided with an elastic member 4, and the accommodating cavity 24 is slidingly arranged in the auxiliary rod 2 and connected with the auxiliary rod 2 through the elastic member 4.

[0046] In the embodiment, the elastic member 4 is a cylindrical spring.

[0047] Specifically, when the hitting end 21 is used to strike the work surface, if a larger striking force is needed, at this time, the vibration force is transmitted into the accommodating cavity 24, the elastic member 4 is compressed accordingly, and then restored, thereby unloading a part of the vibration force, so that the hitting end 21 can strike the work surface smoothly.

[0048] In some embodiments, as shown in Figure 3 , the opening 11 is detachably provided with a cover 5 for plugging the opening 11, and in the first state, the side of the cover 5 away from the operating end 23 is flush with the striking surface of the hammer head 1. Through the arrangement of the cover 5, the surface of the striking surface of the hammer head 1 is flat, so that the work surface can be struck uniformly.

[0049] Specifically, when the hammer head 1 is used to strike the work surface, the cover 5 cooperates with the striking surface of the hammer head 1 to act on the work surface, thereby striking the work surface evenly. Before the hitting end 21 is used to strike the work surface, the operating end 23 is rotated, the rod body 22 is rotated and gradually approaches the opening 11, so that the hitting end 21 pushes open the cover 5, and then the hitting end 21 is used to strike the work surface.

[0050] In some embodiments, as shown in Figure 2 and Figure 4 , the hammer handle 3 includes a first section 31 and a second section 32, the first end of the first section 31 is provided with an inwardly extending connecting channel 311, and the second section 32 has a connecting rod 321 threadedly connected with the connecting channel 311. When the force arm needs to be lengthened or remote work is needed, etc., by rotating the second section 32, the connecting rod 321 moves in the connecting channel 311, thereby lengthening the total length of the hammer handle 3.

[0051] Further, in some embodiments, the connecting rod 321 comprises a main body segment 3211 and a bent segment 3212 rotationally connected with the main body segment 3211, after the rotationally connecting part of the main body segment 3211 and the bent segment 3212 is moved out of the connecting hole 311, the bent segment 3212 is rotated to form a preset included angle between the bent segment 3212 and the main body segment 3211.

[0052] It can be understood that the shapes of the first segment 31, the second segment 32 and the connecting rod 321 can be regular shapes such as cylinders, or even irregular shapes, as long as the worker can stably hold the hammer and the hammer head 1 can stably strike the work surface.

[0053] Specifically, through the arrangement of the bent segment 3212 and the main body segment 3211, when the worker faces some complex construction sites, the worker can adapt to the situation by bending the hammer handle 3 to avoid injury caused by the complex construction site. The specific adjustment method is as follows: first, rotate the second segment 32 to lengthen the total length of the hammer handle 3 until the rotationally connecting part of the main body segment 3211 and the bent segment 3212 is moved out of the connecting hole 311, then rotate the bent segment 3212 to form a preset included angle between the bent segment 3212 and the main body segment 3211. The preset included angle can be limited by arranging damping or limiting structures at the rotationally connecting part to ensure that the included angle is stable and meets the operation requirements. The worker can hold the bent segment 3212 to reduce the influence of the construction site on the striking work.

[0054] In some embodiments, the side wall of the first segment 31 is provided with a groove 312, and the side wall of the second segment 32 is provided with an abutting portion 322. After the preset included angle is formed between the bent segment 3212 and the main body segment 3211, the abutting portion 322 is clamped in the groove 312. Through the clamping cooperation of the abutting portion 322 and the groove 312, the bent segment 3212 and the main body segment 3211 can still be stably connected after being bent, so as to ensure that the hammer stably strikes the work surface.

[0055] In some embodiments, as shown in Figure 1 The operating end 23 further comprises a prying portion 231 having a clamping groove 2311 for clamping a screw rod portion. Through the arrangement of the prying portion 231, the function of the hammer is increased, that is, the screw rod portion is clamped in the clamping groove 2311, and then the screw is smoothly pried.
