Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction inspection technology, and in particular to a structure for a building construction inspection hammer with folding and storage function. Background Technology
[0002] In the construction process, hammers are a common testing tool widely used in structural inspection, material strength testing, and foundation inspection. By striking different components, hammers provide feedback signals about their internal structure, helping engineers assess the quality and stability of buildings or components. Currently, most hammers on the market are fixed tools with relatively simple shapes and structures. However, with the diversification of construction environments and changes in work requirements, the convenience and operability of hammers used for construction inspection are receiving increasing attention.
[0003] However, problems still exist in practical applications. Traditional hammers are generally bulky and have a fixed structure. Especially during long-term on-site inspection work, operators need to carry multiple tools, increasing their workload. Due to limited space or complex working environments, carrying and storing traditional hammers is often inconvenient, affecting work efficiency. To address this technical problem, this application proposes a hammer structure for construction inspection with folding and storage functions. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable and retractable hammer structure for construction inspection. By pressing the fixed column, the restriction on the rotating shaft limit rod is released. The spring and the fixed column work together to precisely control the hammer head inspection angle based on the rotation angle of the rotating component. Pulling the hammer head extends the telescopic rod, which is locked by the fixed groove and the fixed ball, thus meeting the requirements for high-altitude inspection. Pushing the lever downwards releases the lock and retracts the telescopic rod, reducing space occupation.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A construction inspection hammer structure with folding and storage function includes a hammer head, a telescopic rod fixedly connected to the rear end of the hammer head, a folding cylinder connected to the rear end of the telescopic rod via a fixing component, a fixing ball provided on the inner wall of the folding cylinder, a rotating component fixedly connected to the rear end of the folding cylinder, two connecting plates connected inside the rotating component via an adjustment component, a handle fixedly connected to the rear end of the connecting plates, and a placement groove provided on the front side of the handle, the placement groove being adapted to the size of the folding cylinder.
[0007] Furthermore, the fixing component includes a limiting ring that is slidably connected to the inside of the folding cylinder. The rear end of the limiting ring is connected to the inside of the folding cylinder by a spring, and levers are fixedly connected to both the upper and lower ends of the limiting ring.
[0008] Furthermore, the outer wall of the folding cylinder is provided with a sliding groove, and the lever is slidably connected inside the sliding groove.
[0009] Furthermore, the adjustment assembly includes a rotating shaft fixedly connected to the inside of the rotating component and a fixed column disposed on the top of the upper connecting plate, the rear end of which is connected to the inside of the upper connecting plate by a spring.
[0010] Furthermore, a limit rod is provided on the outer periphery above the rotating shaft, and the fixing post is located between the gaps of the limit rod.
[0011] Furthermore, a fixing groove is provided on the outer periphery of the rear end of the telescopic rod, and the fixing ball is disposed inside the fixing groove.
[0012] Furthermore, the rotating component is rotatably connected to one side of the two connecting plates.
[0013] This utility model has the following beneficial effects:
[0014] In this invention, pulling the hammer head extends the telescopic rod, which engages with the fixed ball in the fixed groove to lock, thus satisfying the requirements for high-altitude inspection; pushing the lever downwards releases the lock and retracts the telescopic rod, reducing space occupation and making it easy to carry. It demonstrates high efficiency, practicality, and portability when switching between different work scenarios.
[0015] In this invention, the restriction on the rotating shaft limiting rod is released by pressing the fixed column. By using the cooperation of the spring and the fixed column, the detection angle of the hammer head can be precisely controlled according to the rotation angle of the rotating part, which can adapt to the detection needs of complex environments and effectively improve the flexibility and accuracy of the detection.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 , Figure 4 and Figure 7 This utility model provides an embodiment of a construction inspection hammer structure with folding and storage function, including a hammer head 1, a telescopic rod 2 fixedly connected to the rear end of the hammer head 1, a folding cylinder 3 connected to the rear end of the telescopic rod 2 via a fixed ball 11, a fixed ball 11 provided on the inner wall of the folding cylinder 3, a rotating component 6 fixedly connected to the rear end of the folding cylinder 3, two connecting plates 13 connected inside the rotating component 6 via a rotating shaft 4, a handle 7 fixedly connected to the rear end of the connecting plate 13, a placement groove provided on the front side of the handle 7, the placement groove being adapted to the size of the folding cylinder 3, a fixed groove provided on the outer periphery of the rear end of the telescopic rod 2, the fixed ball 11 being disposed inside the fixed groove, and the rotating component 6 being rotatably connected to the adjacent side of the two connecting plates 13;
[0027] Specifically, the telescopic rod 2 is nested inside the folding cylinder 3. Initially, it is in the retracted position. When it is necessary to inspect a high-rise building, the operator holds the hammer head 1 and pulls it outward. Due to the pulling force, the telescopic rod 2 begins to move outward along the axial direction inside the folding cylinder 3. During the movement, when the fixing groove at the rear end of the telescopic rod 2 moves to be exactly aligned with the position of the pre-set fixing ball 11 inside the folding cylinder 3, it is locked into the fixing groove. In this way, the telescopic rod 2 is stably fixed in the extended position, thereby effectively extending the length of the entire inspection device, allowing the operator to easily perform tapping inspection operations on high-rise building parts.
[0028] Reference Figure 2 and Figure 3 The folding cylinder 3 has a sliding connection of a limiting ring 8 inside. The rear end of the limiting ring 8 is connected to the inside of the folding cylinder 3 by a spring 10. Both the upper and lower ends of the limiting ring 8 are fixedly connected to levers 9. The outer wall of the folding cylinder 3 has a groove, and the levers 9 are slidably connected inside the groove.
[0029] Specifically, pushing the lever 9 downwards causes the limiting ring 8 to move inside the folding cylinder 3, compressing the spring 10 and disengaging the limiting ring 8 from the position above the fixed ball 11. Then, pushing the telescopic rod 2 causes the fixed ball 11 to move out of the fixing groove, allowing the telescopic rod 2 to retract back into the folding cylinder 3. This significantly reduces the overall space occupied by the device, making it easier to carry and store, and improving the practicality and portability of the device in different construction scenarios.
[0030] Reference Figure 5 and Figure 6 The rotating part 6 is internally fixedly connected to the rotating shaft 4 and the upper connecting plate 13. The top of the fixed post 5 is provided with a fixed post 5. The rear end of the fixed post 5 is connected to the interior of the upper connecting plate 13 by a spring 12. A limit rod is provided on the outer periphery above the rotating shaft 4. The fixed post 5 is located between the gaps of the limit rods.
[0031] Specifically, when the device needs to be deployed for angle adjustment, the operator presses the fixing column 5, compressing the spring 12. The fixing column 5 retracts completely into the connecting plate 13, releasing the fixation of the limiting rod. At this time, the folding cylinder 3, along with the hammer 1 and other structures, can be extended from the placement slot. As the rotating part 6 rotates, when it reaches the appropriate angle, the fixing column 5 is released, and the spring 12 returns to its original deformation, lifting the fixing column 5 and blocking the rotation path of the limiting rod again. This locks the angle of the rotating part 6, thereby precisely controlling the detection angle of the hammer 1, so that it can adapt to the detection needs of complex building parts such as corners, beams, and columns.
[0032] Working principle: First, pressing the fixing post 5 deforms the spring 12 below it, compressing the fixing post 5 into the connecting plate 13. At this time, the fixing effect of the fixing post 5 on the limiting rod on the rotating shaft 4 is released, allowing the folding cylinder 3 and its connected structure to be extended from the placement slot on the handle 7. Then, according to the rotation angle of the rotating component 6, the fixing post 5 is released, causing the spring 12 to lift the fixing post 5, thus blocking the rotation path of the upper limit rod on the rotating shaft 4. This allows control of the rotation angle of the rotating component 6, thereby controlling the detection angle of the hammer head 1, improving the device's ability to operate in complex environments. When high-altitude applications are required... When inspecting a building, the telescopic rod 2 connected to it can be moved inside the folding cylinder 3 by pulling the hammer head 1. This moves the fixing groove at the rear of the telescopic rod 2 to the fixing ball 11 inside the folding cylinder 3, thereby fixing the telescopic rod 2. This facilitates the inspection of buildings at high altitudes. Furthermore, by pushing the lever 9 downward, the limiting ring 8 moves inside the folding cylinder 3, thereby compressing the spring 10 connected to it and moving it away from the top of the fixing ball 11. Then, by pushing the telescopic rod 2, the fixing ball 11 is moved out of the fixing groove, thus retracting the telescopic rod 2, reducing the space occupied by the device, and making it more convenient to carry.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
