In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present application proposes a galvanized steel coating adhesion testing device, including: a shell 110, an open end of the shell 110 is formed with a matching portion 1; an energy storage component 120, a part of the energy storage component 120 is arranged in the shell 110; an impact hammer head 130, the impact hammer head 130 is connected to the energy storage component 120; and a firing component 140, the firing component 140 is used to unlock or lock the energy storage component 120.

[0036] The galvanized steel coating adhesion test device provided by the embodiment of the present application includes a housing 110, an energy storage component 120, an impact hammer 130 and a firing component 140. During use, the galvanized steel coating adhesion test device can be held by hand, and then the anastomosis portion 1 on the housing 110 is aligned with the part to be tested, and then the energy storage component 120 is used to store energy for the impact hammer 130, and the energy storage component 120 is unlocked by the firing component 140. The energy storage component 120 releases the stored energy to drive the impact hammer 130 to impact the part to be tested, and then by checking or observing the condition of the galvanized layer on the surface of the workpiece to be tested, it can be known whether the galvanized steel coating adhesion is qualified. The galvanized steel coating adhesion test device provided by the embodiment of the present application improves the convenience of testing, and a spring energy storage galvanized steel coating adhesion test device with higher versatility and lower requirements for sample placement has been developed. The device is small in size, has low requirements for tower material placement, is highly versatile, and can meet the requirements of various field tests.

[0037] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the galvanized steel coating adhesion testing device further includes: at least two guide rings 2, the guide rings 2 are arranged on the inner side of the matching portion 1, and are used to guide the impact hammer head 130.

[0038] In this technical solution, the galvanized steel coating adhesion testing device may further include a guide ring 2. Through the setting of the guide ring 2, when the energy storage component 120 stores energy or the energy storage component 120 releases stored energy to drive the impact hammer head 130 to move, the running path of the impact hammer head 130 can be constrained, so that the impact hammer head 130 can apply impact more accurately, thereby improving the detection effect.

[0039] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the energy storage assembly 120 includes: a pull rod 4, one end of which is connected to the impact hammer head 130, and the other end extends out of the shell 110; and an energy storage spring 3, which is sleeved on the pull rod 4.

[0040] In this technical solution, the structural composition of an energy storage component 120 is further provided. The energy storage component 120 may include a pull rod 4 and an energy storage spring 3 mounted on the pull rod 4. The pull rod 4 may move relative to the housing 110. By pulling the pull rod 4, the pull rod 4 drives the energy storage spring 3 to be compressed to achieve energy storage.

[0041] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the firing assembly 140 includes: a locking plate 5, which is movably connected to the shell 110, and the locking plate is used to unlock or lock the pull rod 4; a firing rod 6, which is connected to the locking plate 5 and is used to adjust the position of the locking plate 5.

[0042] In this technical solution, the structural composition of the firing assembly 140 is further provided. The firing assembly 140 may include a locking plate 5 and a firing rod 6. During operation, a slot may be formed on the pull rod 4. After the pull rod 4 is pulled to compress the energy storage spring 3, the locking plate 5 will be snapped into the slot, and the energy storage assembly 120 completes energy storage. Then, when impact detection is required, the position of the locking plate 5 can be adjusted by the firing rod 6 to unlock the pull rod 4. The energy storage spring 3 releases energy to drive the impact hammer 130 to impact the test piece.

[0043] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the energy storage assembly 120 further includes: a guide rod 7 , and the guide rod 7 passes through the locking plate 5 .

[0044] In this technical solution, the energy storage component 120 may include a guide rod 7, based on which the guide rod 7 can restrict the movement trajectory of the pull rod 4 during the process of storing and releasing energy of the component, thereby enabling the movement of the pull rod 4 to be smoother.

[0045] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, there are two locking plates 5 , the two locking plates 5 are semicircular, the two locking plates 5 are arranged opposite to each other, the locking plates 5 are semicircular, and a firing rod 6 is arranged on each locking plate 5 .

[0046] In this technical solution, an arrangement of the locking plates 5 is further provided. There may be two locking plates 5. The pull rod 4 is clamped by two semicircular locking plates 5, which can make locking and unlocking of the energy storage assembly 120 more convenient.

[0047] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the firing assembly 140 includes: a tension spring 8, which is connected to the two locking plates 5, so that the two locking plates 5 are brought closer to each other in the absence of external force.

[0048] In this technical solution, the firing assembly 140 may further include a tension spring 8, which is connected to the two locking plates 5. In the absence of external force, the two locking plates 5 are brought close to each other. Based on this, the two locking plates 5 can be locked in the grooves above the pull rod 4, and the locking plates 5 can be driven to move by moving the firing rod 6, thereby unlocking the pull rod 4.

[0049] In a feasible implementation, the anastomotic portion 1 can be detachably connected to the housing 110. This arrangement facilitates the assembly of the galvanized steel coating adhesion test device.

[0050] In a feasible implementation, there are multiple anastomotic parts 1, and the styles of the multiple anastomotic parts 1 are different.

[0051] In this technical solution, there can be multiple anastomotic parts 1, and the styles of the multiple anastomotic parts 1 are different, so that the galvanized steel coating adhesion testing device can adapt to test surfaces of different shapes, which can increase the scope of application of the galvanized steel coating adhesion testing device.

[0052] In a feasible implementation manner, an anti-slip portion is formed on the outer wall of the housing 110. Such an arrangement makes it easier to hold the galvanized steel coating adhesion test device, making the operation more convenient.

[0053] In some examples, the housing 110 may be cylindrical to facilitate gripping by a user.

[0054] In a feasible implementation manner, the end of the impact hammer head 130 is arc-shaped. Such an arrangement can improve the impact strength, further improve the detection effect, and help reduce the volume of the galvanized steel coating adhesion test device.
