Description

Technical Field

[0001] This utility model relates to a portable hammer impact test device for galvanized coating, belonging to the field of hammer impact test devices. Background Technology

[0002] The hammer impact tester is suitable for testing the adhesion of galvanized layers. It uses a falling hammer to strike the sample to test whether the galvanized layer meets the standard.

[0003] Chinese utility model patent CN210221734U discloses a hammer impact testing device for galvanized coatings. The device includes a base, a hammer head, and a hammer handle. One end of the hammer handle is rotatably connected to the base, and the other end is fixedly connected to the hammer head. A support is vertically mounted on the base, and the support has a C-shaped elastic groove for fixing the hammer handle. By providing this C-shaped elastic groove with a certain degree of elasticity, the hammer handle can be locked into the groove when not performing a hammer impact test, effectively preventing injury from the hammer head due to free rotation of the handle. This utility model effectively fixes the hammer handle when not performing a hammer impact test. However, existing hammer impact testing devices are relatively bulky, weighing approximately 3.5 kg, making them inconvenient to carry. Furthermore, to improve test accuracy, hammer impact tests are usually performed at different locations on the sample. The traditional method involves manually moving the sample to adjust the hammer position, requiring extensive experience. However, this method can easily cause the actual hammer impact position to deviate from the target hammer impact position, thus affecting test accuracy.

[0004] Therefore, there is a need for a portable hammer impact test device for galvanized coatings to improve portability and test accuracy. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, to provide a portable galvanized layer hammer impact test device that improves portability and test accuracy.

[0007] The movable seat includes a seat body and two support plates. The two support plates are fixedly mounted on the base and are arranged horizontally at intervals. The seat body is located between the two support plates and is horizontally slidably connected to the two support plates. The horizontal sliding direction of the seat body is perpendicular to the horizontal arrangement direction of the two support plates. A driving component is connected to one side of the seat body. The driving component is used to drive the seat body to slide horizontally. The hammer body is rotatably connected to the seat body through a pin. The pin is horizontally arranged and perpendicular to the horizontal sliding direction of the seat body.

[0008] Preferably, the base is magnetic.

[0032] like Figure 1-9 As shown, a portable galvanized layer hammer impact test device in this embodiment includes a base 100, a hammer body 200 and a movable seat 300. The base 100 is magnetically attached, the movable seat 300 is disposed on the base 100, the hammer body 200 is connected to the movable seat 300, and the movable seat 300 drives the hammer body 200 to move in the horizontal direction.

[0033] The movable seat 300 includes a seat body 301 and two support plates 302. The two support plates 302 are fixedly mounted on the base 100 and are arranged at intervals in the horizontal direction. The seat body 301 is located between the two support plates 302 and is horizontally slidably connected to the two support plates 302. The horizontal sliding direction of the seat body 301 is perpendicular to the horizontal arrangement direction of the two support plates 302. A driving component is connected to one side of the seat body 301. The driving component is used to drive the seat body 301 to slide horizontally. The hammer body 200 is rotatably connected to the seat body 301 through a pin 303. The pin 303 is arranged horizontally and is perpendicular to the horizontal sliding direction of the seat body 301.

[0034] The support plate 302 is provided with a scale.

[0035] Both support plates 302 are provided with strip grooves 304, which are parallel to the horizontal sliding direction of the seat 301. An opening 305 is provided on one side of the seat 301, and the pin 303 passes through the opening 305 and the two strip grooves 304 in sequence.

[0036] Positioning discs 306 are detachably fixed at both ends of the pin 303. The two positioning discs 306 correspond one-to-one with the two support plates 302. The positioning discs 306 are attached to the side of the support plate 302 away from the seat 301. The function of the positioning discs 306 is to prevent the pin 303 from detaching from the slot 304.

[0037] The diameter of the pin 303 is equal to the width of the groove 304;

[0038] The hammer body 200 includes a hammer handle 201 and a hammer head 202. One end of the hammer handle 201 is located in the opening 305, and the hammer head 202 is disposed at the other end of the hammer handle 201. The pin 303 passes through the end of the hammer handle 201 away from the hammer head 202.

[0039] The driving component includes a push rod 307 and a fixing block 308. The fixing block 308 is fixedly mounted on the base 100 and is located on the side of the seat 301 away from the opening 305. The push rod 307 is horizontally arranged and perpendicular to the pin 303. The push rod 307 passes through the fixing block 308 and is threadedly connected to the fixing block 308. One end of the push rod 307 is inserted into the opening 305, and the other end of the push rod 307 is provided with a knob 309. The push rod 307 is rotatably connected to the seat 301. The sliding direction of the push rod 307 is positioned between the push rod 307 and the seat 301 by a limiting member.

[0040] The limiting component includes two limiting rings 310, both of which are coaxially fixedly sleeved on the push rod 307. One of the limiting rings 310 abuts against the inner wall of the opening 305 near the fixing block 308, and the other limiting ring 310 abuts against the side of the seat 301 away from the opening 305. Both limiting rings 310 are locked to the push rod 307 by locking screws 311.

[0041] A level (not shown in the attached figure) is installed on the base 100. By observing the level, it is ensured that the base 100 is in a horizontal state, thus ensuring the authenticity of the test results.

[0042] During use, the base 100 is magnetically attached to the galvanized specimen. In fact, the base material of the galvanized specimen is a magnetically attachable material. Then, the hammer handle 201 is placed in a vertical position, that is, the hammer head 202 is located at the top of the hammer handle 201. Then, the hammer handle 201 is released, and the hammer head 202 drives the hammer handle 201 to rotate around the pin 303 by its own gravity until the hammer head 202 hits the specimen and stops, thus completing one hammering test.

[0043] Next, rotate knob 309 to make push rod 307 rotate on fixed block 308 and move horizontally. The horizontal movement of push rod 307 drives seat 301 to move synchronously through limit ring 310, and at the same time drives pin 303 to move synchronously in slot 304. The movement of pin 303 also drives hammer handle 201 to move synchronously. The moving distance depends on the actual test requirements. Then, hammer test is carried out again.

[0044] The total number of hammer tests depends on the test requirements;

[0045] By inspecting the surface condition of the zinc layer, it can be determined whether the adhesion of the zinc layer meets the standard requirements.

[0046] In addition, the portable galvanized layer hammer impact test device weighs about 350 grams, while the existing technology has a support frame, which makes the overall weight relatively heavy, with an overall weight of about 3.5 kilograms. Thus, the portable galvanized layer hammer impact test device reduces the weight and improves the portability.

[0047] Secondly, by driving the horizontal movement of the base 301, the hammer 200 is moved horizontally, thereby adjusting the hammering position of the specimen. The position adjustment distance is controlled by rotating the push rod 307, eliminating the need for manual adjustment of the specimen and improving the accuracy of hammering position adjustment, which in turn improves the test accuracy.

[0048] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
