Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing test equipment, and in particular to a galvanizing hammer impact test device. Background Technology

[0002] Galvanizing is an important process for improving the corrosion resistance of steel, and the adhesion strength of the galvanized layer is one of the key indicators for evaluating the quality of galvanizing. According to relevant standards, the hammer impact test is a commonly used method to test the adhesion of the galvanized layer. This method uses a specific testing device to impact the surface of the galvanized specimen with a hammer at a specified energy, and the adhesion is judged by checking the degree of peeling off the zinc layer.

[0003] For example, the hammer impact testing device for galvanized coating disclosed in patent number CN201920757956.4 typically includes a base, a hammer handle, and a hammer head. One end of the hammer handle is rotatably connected to the base, and a support is vertically installed on the base, giving the entire device a stable inverted "T" shape. However, such devices occupy a large space, are highly integrated, and are inconvenient to store when transported, stored, or carried to the site, which increases transportation and storage costs.

[0004] Based on this, the applicant is considering designing a galvanized hammer impact test device that can be stored. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a galvanized hammer impact test device that can be stored.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A galvanized hammer impact test device includes a base and a test hammer. The base includes a mounting plate and at least one rotating plate. The rotating plate is rotatably connected to the mounting plate via a rotating structure. The bottom end of the test hammer is hinged to the top side of the mounting plate. The rotating support plate can rotate around the rotating structure to a horizontally extended or vertically retracted state, and also includes a positioning structure for keeping the rotating support plate in a horizontally extended state.

[0007] The working principle and advantages of this galvanized hammer impact testing device are as follows: When a hammer impact test is required for galvanizing, the rotating support plate is rotated around the rotating structure to a laterally extended state, and then locked in this state by the positioning structure. The extended rotating support plate and the mounting support plate form a base with a large supporting area, which can resist the impact generated by the test hammer falling freely onto the galvanized parts, preventing the overall device from shifting or overturning, and ensuring the accuracy and reliability of the test data. After the hammer impact test, the locking of the positioning structure is released, and the rotating support plate is rotated around the rotating structure again to a vertically retracted state. This reduces the overall volume of the device, making it easier to store, transport, or carry.

[0008] Furthermore, the rotating structure includes a fixed shaft fixedly connected to the side wall of the mounting plate, and the rotating plate has a shaft hole through which the fixed shaft passes.

[0009] Furthermore, the positioning structure includes a cross groove formed at the free end of the fixed shaft, a limiting groove formed at the shaft hole of the rotating support plate corresponding to the cross groove, and a limiting member. The limiting member is provided with a cross protrusion that can extend into the cross groove and the limiting groove together.

[0010] Furthermore, a first stop block is fixedly connected to the bottom side of the mounting plate, and a second stop block is fixedly connected to the bottom of the rotating plate.

[0011] Furthermore, the first stop block and the second stop block are respectively provided with corresponding connecting holes.

[0012] Furthermore, a fixing frame is installed on the mounting plate, and the fixing frame is connected to a release block that is detachably connected to the top of the test hammer.

[0013] Furthermore, a connecting block is fixedly connected to the top of the test hammer, and a release groove is provided on the release block for the connecting block to extend into. A magnetic block that is magnetically connected to the connecting block is movably disposed in the release groove.

[0014] Furthermore, the connecting block has a first connecting hole, and the releasing block has a second connecting hole corresponding to the first connecting hole and communicating with the releasing groove.

[0015] Furthermore, the mounting plate is rotatably connected to two symmetrically arranged rotating support plates.

[0016] Furthermore, it also includes a storage box, which includes a storage cover and a storage base detachably connected thereto. The rotating support plate has a groove on its side wall, and the inner side wall of the storage cover has a sliding strip corresponding to the groove protruding from it. Attached Figure Description

[0019] Refer to together Figures 1 to 7 This embodiment provides a galvanized hammer impact test device, including a base and a test hammer 310. The base includes a mounting plate 100 and at least one rotating plate 200. The rotating plate 200 is rotatably connected to the mounting plate 100 through a rotating structure. The bottom end of the test hammer 310 is hinged to the top side of the mounting plate 100. The rotating support plate 200 can rotate around the rotating structure to a horizontally extended or vertically retracted state, and also includes a positioning structure for keeping the rotating support plate 200 in a horizontally extended state.

[0020] In this embodiment, when a hammer impact test for galvanizing is required, the rotating support plate 200 is rotated around the rotating structure to a laterally unfolded state, and then the rotating support plate 200 is locked in the laterally unfolded state by the positioning structure. The unfolded rotating support plate 200 and the mounting support plate 100 form a base with a large area, which can resist the impact generated when the test hammer 310 falls freely to hammer the galvanized part, preventing the device from shifting or overturning. After the hammer impact test is completed, the locking of the positioning structure is released, and the rotating support plate 200 is rotated around the rotating structure again to a vertically folded state. This reduces the overall outline volume of the device, making it easier to store, transport, or carry.

[0021] Preferably, such as Figures 1 to 7 As shown, the rotating structure includes a fixed shaft 110 fixedly connected to the side wall of the mounting plate 100, and a shaft hole 210 is provided on the rotating plate 200 for the fixed shaft 110 to pass through; the fixed shaft 110 and the shaft hole 210 cooperate to form a rotating structure, allowing the rotating plate 200 to rotate stably.

[0022] Preferably, such as Figures 1 to 7 and Figure 9As shown, the positioning structure includes a cross groove 120 formed at the free end of the fixed shaft 110, a limiting groove 220 corresponding to the cross groove 120 formed at the shaft hole 210 of the rotating support plate 200, and a limiting member 600. The limiting member 600 is provided with a cross protrusion 610 that can extend into the cross groove 120 and the limiting groove 220 together. When the rotating support plate 200 is rotated to a position where it is fully horizontally extended or vertically retracted, the limiting groove 220 formed on the end face of its shaft hole 210 is aligned with the cross groove 120 formed on the free end of the fixed shaft 110. Then, the cross protrusion 610 on the limiting member 600 is inserted into the aligned cross groove 120 and the limiting groove 220 to restrict the rotation of the rotating support plate 200, so that the rotating support plate 200 can stably maintain the horizontally extended or vertically retracted state. It is convenient and intuitive to use.

[0023] Preferably, such as Figures 1 to 7 As shown, a first stop block 130 is fixedly connected to the bottom side of the mounting plate 100, and a second stop block 230 is fixedly connected to the bottom of the rotating plate 200. When the rotating plate 200 is rotated to the unfolded state, the side of the second stop block 230 on the rotating plate 200 will contact the side of the first stop block 130 on the mounting plate 100, preventing the rotating plate 200 from continuing to rotate, which can effectively prevent the rotating plate 200 from rotating excessively.

[0024] Preferably, such as Figure 6 and Figure 7 As shown, the first stop block 130 and the second stop block 230 are respectively provided with corresponding connecting holes 21. When the rotating support plate 200 is rotated to the unfolded state, the side of the second stop block 230 on the rotating support plate 200 will contact the side of the first stop block 130 on the mounting support plate 100, and the connecting holes 21 on both will be aligned. Then, the first stop block 130 and the second stop block 230 can be firmly connected together by a connecting structure, such as bolts and nuts, so that the mounting support plate 100 and the rotating support plate 200 form a more solid and stable base in the horizontally unfolded state, preventing the above positioning structure from failing.

[0025] Preferably, such as Figures 1 to 5As shown, a mounting bracket 400 is installed on the mounting plate 100. The mounting bracket 400 is connected to a release block 420 that is detachably connected to the top of the test hammer 310. The mounting bracket 400 provides a stable support structure. Since the release block 420 on the mounting bracket 400 is detachably connected to the top of the test hammer 310, the test hammer 310 can be rotated to a predetermined starting height during use, and then the release block 420 can be connected to the top of the test hammer 310, so that the top of the test hammer 310 (hammer head) is suspended in the air and in a stable ready-to-trigger state. When hammering is required, the connection between the release block 420 and the top of the test hammer 310 is released, allowing the hammer to strike. The test hammer 310 can fall freely under the action of gravity, with its bottom hinge point as the axis, to hammer the galvanized part to be tested. After the hammering is completed, the test hammer 310 can be rotated back to connect with the release block 420, ready for the next test. Specifically, the mounting plate 100 is detachably connected to the hinge seat 300, the bottom end of the test hammer 310 is hinged to the hinge seat 300, the fixing frame 400 is detachably connected to the mounting plate 100, and the release block 420 is detachably connected to the fixing frame 400, which facilitates the maintenance and replacement of the parts. Specifically, the top of the test hammer 310 is set so that the center of gravity of the hammer head is offset towards the pointed end, ensuring that the test hammer 310 can fall freely and smoothly.

[0026] Preferably, such as Figures 1 to 5 As shown, a connecting block 320 is fixedly connected to the top of the test hammer 310. A release groove 430 is provided on the release block 420 for the connecting block 320 to extend into. A magnetic block 440, which is magnetically connected to the connecting block 320, is movably disposed in the release groove 430. When the test hammer 310 is rotated to the point where the connecting block 320 at the top extends into the release groove 430 of the release block 420, the connecting block 320 will be magnetically attracted to the magnetic block 440 movably disposed in the release groove 430, keeping the test hammer 310 in the triggered state. When the test hammer 310 needs to hammer the galvanized part, simply move the magnetic block 440 in the release groove 430 to release the magnetic attraction between the magnetic block 440 and the connecting block 320. The operation is quick and simple. Specifically, the magnetic block 440 is slidably disposed in the release groove 430.

[0027] Preferably, such as Figures 1 to 7As shown, the connecting block 320 has a first connecting hole 330, and the release block 420 has a second connecting hole 431 corresponding to the first connecting hole 330 and communicating with the release groove 430. When the connecting block 320 extends into the release groove 430 and the first connecting hole 330 and the second connecting hole 431 are aligned, the release block 420 and the connecting block 320 can be more stably connected together by a connecting structure, such as a bolt or a connecting pin passing through the aligned first connecting hole 330 and the second connecting hole 431. When multiple experiments are required, the magnetic block 440 can be used to connect the connecting block 320. When storage, transportation, or carrying is required, the magnetic block 440 can be used to connect the connecting block 320, and the release block 420 and the connecting block 320 can also be connected by a connecting structure to prevent the test hammer 310 from shifting, shaking, or falling, thereby improving safety and reliability.

[0028] Specifically, such as Figures 3 to 5 As shown, a stop rod 410 is fixedly connected to the connecting block 320 to prevent the test hammer 310 from rotating excessively.

[0029] Preferably, such as Figures 1 to 4 As shown, two symmetrically arranged rotating support plates 200 are rotatably connected to the mounting support plate 100. When the two rotating support plates 200 are rotated to the horizontally extended position at the same time, the area of ​​the base is further increased, which further prevents the overall device from shifting or overturning. When the two rotating support plates 200 are rotated to the vertical storage position at the same time, they are symmetrically arranged on both sides of the main support plate and its fixed frame 400 and test hammer 310, which is neat, compact and occupies little space.

[0030] Specifically, such as Figures 1 to 4 As shown, at least two leveling screws 240 are provided on the rotating support plate 200 to facilitate leveling of the entire device. More specifically, if only one rotating support plate 200 is provided, at least two leveling screws 240 can be provided on the mounting support plate 100. More specifically, a level (not shown in the figure) can also be provided on the mounting support plate 100.

[0031] Preferably, such as Figure 6 and Figure 8As shown, the galvanizing hammer impact test device also includes a storage box, which includes a storage cover 510 and a storage base 520 detachably connected to it. A groove 250 is provided on the side wall of the rotating support plate 200, and a sliding strip 511 corresponding to the groove 250 is protruding from the inner side wall of the storage cover 510. In use, the rotating support plate 200 is rotated to a vertically retracted state, and then the rotating support plate 200 with the mounting plate 100 or higher is placed into the storage base. Then, the sliding strip 511 protruding from the side wall of the storage cover 510 is aligned with the side wall of the rotating support plate 200. The slide 250 is opened, and the storage cover 510 is pushed along the slide 250 direction, and then the storage cover 510 is connected to the storage base 520 to form a closed, collision-proof, and dustproof space, which improves the protection while further improving the convenience of transportation, storage and carrying; the cooperation of the slide bar 511 and the slide 250, together with the aforementioned limiting member 600, can minimize the rotation of the rotating support plate and prevent damage; specifically, the storage cover 510 and the storage base 520 can be detachably connected by a quick-release connection structure in the prior art, such as a buckle.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
