Description

Technical Field

[0001] This application belongs to the field of construction tools technology, specifically relating to a magnetic anti-puncture integrated pry bar for formwork removal. Background Technology

[0002] During construction, a large number of nails used to secure formwork are often scattered on the construction site. These nails not only easily cause foot injuries to construction workers but also affect the normal operation of construction machinery, posing a significant safety hazard. Furthermore, the removal of concrete formwork is often necessary during construction, requiring specialized prying tools. However, existing prying tools have limited functionality and cannot handle the collection of nails.

[0003] Currently, some magnetic tools for attracting nails have appeared on the market, but most of them have a simple structure, consisting only of a rod and a magnet, and have many shortcomings: First, the length is fixed, and it is impossible to adjust the length according to different construction scenarios, making it difficult to collect nails that are high up or far away; second, the magnet is directly exposed and is easily damaged by collisions, and the attracted nails are not easy to clean, requiring manual peeling, which is cumbersome; third, the function is limited, only used for attracting nails, and cannot meet other construction needs such as formwork removal, causing construction workers to need to carry multiple tools, increasing their workload.

[0004] Therefore, there is an urgent need for a construction site tool that is structurally sound, multifunctional, and easy to use, in order to solve the aforementioned problems in existing technologies. Utility Model Content

[0005] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a magnetic anti-puncture integrated pry bar for formwork removal. This application realizes the dual functions of nail adsorption and collection and concrete formwork removal, and at the same time has the characteristics of adjustable length, easy nail cleaning, and safe and reliable use.

[0006] The technical solution adopted by this application to solve its existing problems is: A magnetic anti-puncture template removal integrated pry bar includes a telescopic rod, a pry plate, and a magnetic component.

[0007] The pry bar and the magnetic suction assembly are respectively located at both ends of the telescopic rod.

[0008] The magnetic attraction assembly includes a mounting base and a strong magnetic block. The mounting base is detachably connected to the end of the telescopic rod, and the strong magnetic block is located below the mounting base.

[0009] Furthermore, the outer cover of the strong magnetic block is equipped with a protective sleeve, which is detachably connected to the mounting base.

[0010] Furthermore, the end of the pry bar is provided with an arc-shaped pry head, the edge of the arc-shaped pry head is provided with a serrated cutting edge, and a weight-reducing groove is provided in the middle of the pry bar.

[0011] Furthermore, a scraper assembly is fitted onto the outside of the magnetic suction assembly.

[0012] The scraper assembly includes a cylindrical scraper body, which is fitted over the protective sleeve, with its inner wall abutting against the outer wall of the protective sleeve. The scraper body is fitted over the outside of the mounting ring, and the two are snapped together or fixedly connected by bolts. A support plate is fixed above the mounting ring, and a sliding sleeve is fixed above the central through hole of the support plate. The sliding sleeve is fitted onto the fixed tube.

[0013] Furthermore, a limiting boss is provided on the outside of the fixed tube, which limits the highest position of the scraper assembly.

[0014] A spring is fitted onto the fixed tube, with its upper and lower ends abutting against the bottom surface of the support plate and the mounting base, respectively.

[0015] Furthermore, the fixed tube is fitted with an anti-slip grip sleeve.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: (1) This device integrates the dual functions of nail adsorption and collection and concrete formwork removal. The two ends of the telescopic rod are connected to the pry plate and the magnetic component respectively. Construction workers do not need to carry multiple tools, which effectively reduces the workload and improves construction efficiency.

[0017] (2) The telescopic rod adopts a multi-stage sleeve structure and achieves stable positioning through a positioning mechanism. The length can be flexibly adjusted according to different construction scenarios, making it easy to reach nails at high or far places. It also facilitates the adjustment of the lever arm when removing the template, improving the ease of operation.

[0018] (3) A scraper assembly with an elastic reset component is provided. After the nail is adsorbed, the scraper body can be pushed down to scrape the nail into the collection container. After releasing, the elastic reset component drives the scraper to automatically reset. The operation is simple and efficient, and there is no need to manually peel off the nail.

[0019] (4) The protective sleeve in the magnetic attraction assembly can effectively protect the strong magnetic block from collision damage, and at the same time prevent the nail from directly contacting the magnet rigidly; the serrated blade on the pry plate facilitates quick separation of the template, and the arc-shaped pry head improves the fit with the template; the non-slip grip and shock-absorbing pad of the grip assembly improve grip stability and reduce the impact of operation vibration on the human body.

Detailed Implementation

[0023] The attached figure shows the preferred embodiment of the magnetic anti-puncture template removal integrated pry bar. The following is a more detailed description of this application in conjunction with the attached figure.

[0024] Depend on Figures 1 to 4 As shown, a magnetic anti-puncture template removal integrated pry bar includes a telescopic rod 1, a pry plate 2, a magnetic component 3, a scraper component 4, a spring 5, and a gripping component.

[0025] The telescopic rod 1 has a three-stage sleeve structure, including a fixed tube 101, an adjusting tube 102, and an end tube 103 that are sequentially sleeved together. The fixed tube 101 and the adjusting tube 102, as well as the adjusting tube 102 and the end tube 103, are axially positioned via a positioning mechanism. The positioning mechanism includes a positioning pin, a return spring, and a pressing cap. Multiple positioning holes are spaced axially on the walls of the adjusting tube 102 and the end tube 103. Mounting holes are also provided on the walls of the fixed tube 101 and the adjusting tube 102. The return spring is positioned within the mounting hole. One end of the positioning pin is connected to the return spring, and the other end extends out of the mounting hole and engages with the positioning hole. The pressing cap is fixedly connected to the end of the positioning pin extending out of the mounting hole. In use, pressing the pressing cap compresses the return spring and retracts it into the mounting hole. At this time, the adjusting tube 102 or the end tube 103 can be pulled to adjust the overall length of the telescopic rod 1. After adjusting to the appropriate position, releasing the pressing cap allows the return spring to push the positioning pin back into the corresponding positioning hole, thus fixing the length.

[0026] The pry bar 2 is fixedly connected to the end of the end tube 103 away from the fixed tube 101 by welding. The end of the pry bar 2 is provided with an arc-shaped pry head 201. The edge of the arc-shaped pry head 201 is provided with a serrated cutting edge 202. The serrated cutting edge 202 can enhance the interlocking force between the pry bar 2 and the template, facilitating the quick separation of the template from the concrete. A weight-reducing groove 203 is provided in the middle of the pry bar 2. The weight-reducing groove 203 is provided with a reinforcing rib arranged along the length of the pry bar 2. The reinforcing rib and the pry bar 2 are integrally formed. The weight-reducing groove 203 can reduce the weight of the pry bar 2, while the reinforcing rib ensures that the pry bar 2 has sufficient structural strength and avoids deformation during use.

[0027] The magnetic assembly 3 includes a mounting base 301, a strong magnetic block 302, and a protective sleeve 303. A connecting screw sleeve 304 is fixed on the top of the mounting base 301. The external thread of the fixed tube 101 away from the end tube 103 is threadedly engaged to achieve a detachable connection, which facilitates subsequent maintenance or replacement of the magnetic assembly 3.

[0028] The strong magnetic block 302 is a neodymium iron boron magnet and is located below the mounting base 301. A protective sleeve 303 is detachably connected to the end of the mounting base 301 away from the fixing tube 101. The protective sleeve 303 is a stainless steel perforated mesh structure. The protective sleeve 303 can be fitted onto the outside of the mounting base 301 and connected to it via a snap-fit; alternatively, it can be located below the mounting base 301 and connected to it via bolts through its inwardly folded edge. The protective sleeve 303 neither affects the magnetic force of the strong magnetic block 302 nor damages it from impacts, while also preventing nails from directly scratching the surface of the strong magnetic block 302.

[0029] The scraper assembly 4 includes a cylindrical scraper body 401, which is fitted over the protective sleeve 303. Its inner wall abuts against the outer wall of the protective sleeve 303. By sliding the scraper body 401 up and down, the magnetically attracted nails on the outside of the protective sleeve 303 are scraped off. To optimize the scraping effect, the bottom of the scraper body 401 is chamfered.

[0030] The scraper body 401 is sleeved on the outside of the mounting ring 404, and the two are snapped together or fixedly connected by bolts. A support plate 403 is fixed on the top of the mounting ring 404. A sliding sleeve 402 is fixed above the central through hole of the support plate 403. The sliding sleeve 402 is sleeved on the fixed tube 101. A limiting boss 104 is provided on the outside of the fixed tube 101. The limiting boss 104 limits the highest position of the scraper assembly 4.

[0031] A spring 5 is fitted on the fixed tube 101. The upper and lower ends of the spring 5 abut against the bottom surface of the support plate 403 and the mounting base 301, respectively. Under the pushing force of the spring 5, the scraper assembly 4 can be automatically reset.

[0032] The grip components include an anti-slip grip and a shock-absorbing pad. The anti-slip grip is made of rubber and is fitted onto the middle of the fixing tube 101. Its outer wall has a diamond-shaped anti-slip texture. The shock-absorbing pad is made of sponge and is embedded inside the anti-slip grip and fits against the outer wall of the fixing tube 101. It can effectively reduce the vibration generated during operation and improve grip comfort.

[0033] In addition, the anti-slip grip is equipped with a control switch, and the fixed tube 101 contains wires and a rechargeable battery. An LED light is fixed to the side wall of the end tube 103 by a bracket. The control switch, battery, and LED light are connected in series to form a circuit. In dimly lit construction environments, pressing the control switch will turn on the LED light, providing illumination to the work area, facilitating the accurate location of scattered nails and the removal of formwork. After use, pressing the control switch again will turn off the LED light. The battery can be charged via a USB interface, making it convenient to use.

[0034] The working principle of this utility model is as follows: When it is necessary to collect nails scattered on the construction site, adjust the length of the telescopic rod 1 according to the position of the nails through the positioning mechanism, hold the anti-slip grip, align the magnetic component 3 with the nails, and the magnetic force generated by the strong magnetic block 302 will attract the nails through the protective sleeve 303; move the device above the collection container, push the scraper body 401 downward to scrape the nails on the protective sleeve 303 into the container, release the scraper body 401, and the scraper body 401 will automatically reset under the action of the spring 5.

[0035] When it is necessary to remove the concrete formwork, the length of the telescopic rod 1 is adjusted according to the actual situation. The arc-shaped pry head 201 of the pry plate 2 is inserted into the gap between the formwork and the concrete. The formwork is pried open by lever principle. The serrated blade 202 can enhance the biting force between the pry plate 2 and the formwork and improve the removal efficiency. If the light in the construction environment is dark, LED lights can be turned on to provide lighting for the work area.

[0036] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
