Description

Technical Field

[0001] This utility model relates to the field of clamping pliers technology, specifically to a test block clamping pliers. Background Technology

[0002] The high temperature and thermal explosion resistance test of casting coatings mainly involves drying the test block coated with casting coating and placing it in a high temperature furnace. The temperature is then raised to the target temperature at a specified rate, and the coating test block is taken out to check whether melting, flowing, peeling or other phenomena occur.

[0003] In actual testing, multiple coating samples are required for each test. However, most existing sample clamps have simple structures, requiring the sample to be placed down after clamping before being clamped again. This necessitates frequent opening and closing of the furnace door, resulting in low testing efficiency and potentially causing a significant drop in furnace temperature, affecting the heat treatment effect of the coating sample and reducing the accuracy of subsequent tests. Therefore, to address these technical problems, a new sample clamp is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a test block clamp that facilitates the continuous clamping of multiple sets of coating test blocks, improving testing efficiency. Furthermore, it eliminates the need for frequent opening and closing of the furnace door, thus avoiding any impact on the heat treatment effect of the coating test blocks and ensuring the accuracy of subsequent testing.

[0005] A test block clamp, comprising:

[0006] Two sets of clamping rods, which are rotatably connected by a pin;

[0007] A temporary storage assembly includes a push plate and a temporary storage box. The push plate and the temporary storage box are respectively disposed at the front ends of two sets of clamping bars. The temporary storage box has a temporary storage cavity on its side facing the push plate. The bottom surface of the opening of the temporary storage cavity has a first inclined surface with its lower end close to the push plate and extending to the bottom surface of the temporary storage box. The side of the temporary storage box away from the push plate has a discharge port communicating with the temporary storage cavity. The temporary storage box is provided with a baffle that can open and close the discharge port.

[0008] The limiting component includes a stop bar and a spring. The stop bar is slidably disposed on the top surface of the opening of the temporary storage cavity along the height direction of the temporary storage cavity. The top end of the stop bar is connected to the top surface of the opening of the temporary storage cavity through multiple sets of springs. The side of the stop bar near the push plate has a second inclined surface with its high end close to the push plate.

[0009] The beneficial effects of the above-mentioned test block clamp are:

[0010] By rotating the two sets of clamping rods to separate the push plate from the temporary storage box, and then positioning the coating sample between the push plate and the temporary storage box, the two sets of clamping rods are rotated in the opposite direction to close the push plate and the temporary storage box. At this point, the push plate can push the coating sample along the first inclined surface into the temporary storage cavity. Simultaneously, the coating sample abuts against the second inclined surface, causing the stop bar to move upward and the spring to contract. When the coating sample enters the temporary storage cavity and is misaligned with the stop bar, the reaction force of the spring drives the stop bar to move downward and reset. At this point, the vertical surface of the stop bar abuts against the coating sample, preventing the coating sample from falling out of the temporary storage cavity. Repeating the above operation can continuously clamp multiple coating samples. Finally, by opening the discharge port through the baffle, multiple sets of coating samples in the temporary storage cavity can be discharged, facilitating the continuous clamping of multiple sets of coating samples, improving testing efficiency, and eliminating the need for frequent opening and closing of the furnace door, thus avoiding affecting the heat treatment effect of the coating sample and ensuring the accuracy of subsequent testing.

[0011] In one embodiment, the temporary storage box has a slot at the end near the rear end of the clamp bar that communicates with the discharge port. One end of the baffle can pass through the slot and is interference-fitted with the slot. Sliding the baffle can open and close the discharge port. The other end of the baffle is provided with a pull rod.

[0012] In one embodiment, the two sets of clamp bars are respectively provided with grips at their rear ends.

[0013] In one embodiment, both sets of grips are fitted with anti-slip sleeves.

[0014] In one embodiment, both sets of grips are connected to the rear end of the clamp bar via a telescopic assembly, and adjusting the telescopic assembly can drive the grips to move along the length of the clamp bar.

[0015] In one embodiment, the telescopic assembly includes an extension rod and a fixing knob; both sets of clamp bars have insertion holes at their rear ends, one end of the extension rod can slide through the insertion hole along the length direction of the clamp bar, and the other end is connected to the grip. Multiple sets of fixing holes are spaced apart along the length direction of the clamp bar on one side of the extension rod, and the fixing knob is threaded onto the clamp bar. Rotating the fixing knob allows the fixing knob to pass through the fixing hole.

[0016] In one embodiment, a limiting groove is provided at both ends of the temporary storage cavity, and a limiting block is provided at both ends of the stop rod. The two sets of limiting blocks are slidably disposed in the two sets of limiting grooves along the height direction of the temporary storage cavity. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] Please see Figures 1 to 3One embodiment of a test block clamp includes two sets of clamp bars 10, a temporary storage component, and a limiting component. Specifically, the two sets of clamp bars 10 are rotatably connected by a pin 101. The temporary storage component includes a push plate 20 and a temporary storage box 201. The push plate 20 and the temporary storage box 201 are respectively disposed at the front ends of the two sets of clamp bars 10. The temporary storage box 201 has a temporary storage cavity 202 on its side facing the push plate 20. The bottom surface of the opening of the temporary storage cavity 202 is provided with a first inclined surface 203 that is close to the push plate 20 at its lower end and extends to the bottom surface of the temporary storage box 201. The storage box 201 has a discharge port 204 on the side opposite to the push plate 20, which communicates with the temporary storage cavity 202. The temporary storage box 201 is provided with a baffle 205 that can open and close the discharge port 204. The limiting component includes a stop bar 30 and a spring 301. The stop bar 30 is slidably disposed on the top surface of the opening of the temporary storage cavity 202 along the height direction of the temporary storage cavity 202. The top of the stop bar 30 is connected to the top surface of the opening of the temporary storage cavity 202 through multiple sets of springs 301. The side of the stop bar 30 near the push plate 20 has a second inclined surface 302 with a high end close to the push plate 20.

[0030] In the above embodiment, by rotating the two sets of clamps 10, the push plate 20 is separated from the temporary storage box 201, and then the paint sample (not shown) is positioned between the push plate 20 and the temporary storage box 201. Then, the two sets of clamps 10 are rotated in the opposite direction to close the push plate 20 and the temporary storage box 201. At this time, the push plate 20 can push the paint sample along the first inclined surface 203 into the temporary storage cavity 202. At the same time, the paint sample abuts against the second inclined surface 302, causing the stop bar 30 to move upward and the spring 301 to contract. When the paint sample enters the temporary storage cavity 202 and is in contact with the stop bar 30, the spring 301 contracts. When misalignment occurs, the reaction force of spring 301 drives the stop lever 30 to move downwards to reset. At this time, the vertical surface of the stop lever 30 abuts against the coating sample block, preventing the coating sample block from falling out of the temporary storage cavity 202. Repeating the above operation can continuously clamp multiple coating samples. Finally, by opening the discharge port 204 through the baffle 205, multiple sets of coating samples in the temporary storage cavity 202 can be discharged, which facilitates the continuous clamping of multiple sets of coating samples, improves the testing efficiency, and eliminates the need for frequent opening and closing of the furnace door, avoiding affecting the heat treatment effect of the coating sample block and ensuring the accuracy of subsequent testing.

[0031] Please see Figure 2 and Figure 3 In one embodiment, the temporary storage box 201 has a slot 206 at the end near the rear end of the clamp 10 that communicates with the discharge port 204. One end of the baffle 205 can pass through the slot 206 and is interference-fitted with the slot 206. The sliding baffle 205 can open and close the discharge port 204. The other end of the baffle 205 is provided with a pull rod 2051.

[0032] The discharge port 204 can be opened and closed by sliding the baffle 205, which is convenient. The baffle 205 and the slot 206 are interference fit, meaning that the baffle 205 cannot be moved without external force, thus ensuring the stability of the baffle 205 in the state of opening and closing the discharge port 204. In addition, the pull rod 2051 is provided so that the user can hold the pull rod 2051 to drive the baffle 205 to move, and keep it away from the temporary storage box 201 to avoid the risk of burns and improve the safety of the device.

[0033] Please see Figure 1 and Figure 2 In one embodiment, the rear ends of the two sets of clamp bars 10 are respectively provided with handles 102 facing each other. The handles 102 make it convenient for the user to hold the device with one hand and drive the two sets of clamp bars 10 to rotate.

[0034] Based on the above embodiment, both sets of grip ears 102 are further provided with anti-slip sleeves 1021. By providing anti-slip sleeves 1021, the stability of the user holding the grip ears 102 can be improved, and slippage can be avoided.

[0035] Please see Figure 2 and Figure 4 In one embodiment, both sets of grips 102 are connected to the rear end of the clamp bar 10 via a telescopic assembly, and adjusting the telescopic assembly can drive the grips 102 to move along the length of the clamp bar 10.

[0036] In the above embodiments, the overall length of the device can be adjusted by adjusting the telescopic component to drive the handle 102 to move, which makes it easier to reduce the size of the device when it is stored. It also makes it easier to adjust the overall length of the device according to the position of the coating sample block in the high-temperature furnace, thus improving the applicability of the device.

[0037] Specifically, in the above embodiments, the telescopic assembly includes an extension rod 40 and a fixing knob 401; both sets of clamp rods 10 have insertion holes 103 at their rear ends; one end of the extension rod 40 can slide through the insertion hole 103 along the length direction of the clamp rod 10, and the other end is connected to the grip 102; one side of the extension rod 40 has multiple sets of fixing holes 402 spaced apart along the length direction of the clamp rod 10; the fixing knob 401 is threaded onto the clamp rod 10; rotating the fixing knob 401 allows the fixing knob 401 to pass through the fixing hole 402.

[0038] By rotating the fixing knob 401 to disengage it from the currently inserted fixing hole 402, the extension rod 40 can be moved. The movement of the extension rod 40 moves the handle 102, adjusting the overall length of the device and aligning different fixing holes 402 with the fixing knob 401. When the device is adjusted to the appropriate length, rotating the fixing knob 401 in the opposite direction allows it to pass through the currently engaged fixing hole 402, thus fixing the extension rod 40 and securing the device's length. This makes length adjustment convenient. It is understood that the two sets of extension rods 40 move the same distance.

[0039] Please see Figure 2 and Figure 4 In one embodiment, limiting grooves 2021 are provided at both ends of the temporary storage cavity 202, and limiting blocks 303 are provided at both ends of the stop lever 30. The two sets of limiting blocks 303 are slidably disposed in the two sets of limiting grooves 2021 along the height direction of the temporary storage cavity 202. The stability of the movement of the stop lever 30 can be improved by the cooperation of the limiting grooves 2021 and the limiting blocks 303.

[0040] The specific implementation of the above-mentioned test block clamp is as follows:

[0041] By holding the two sets of grips 102 and rotating the two sets of clamps 10, the push plate 20 is separated from the temporary storage box 201. The paint sample is then positioned between the push plate 20 and the temporary storage box 201. The clamps 10 are then rotated in the opposite direction to close the push plate 20 and the temporary storage box 201. At this point, the push plate 20 can push the paint sample along the first inclined surface 203 into the temporary storage cavity 202. Simultaneously, the paint sample abuts against the second inclined surface 302, causing the stop lever 30 to move upward and the spring 301 to contract. When the paint sample enters the temporary storage cavity 202 and is misaligned with the stop lever 30, the spring... The reaction force of 301 drives the stop lever 30 to move downwards and reset. At this time, the vertical surface of the stop lever 30 abuts against the coating sample block to prevent the coating sample block from falling out of the temporary storage cavity 202. Repeating the above operation can continuously clamp multiple coating samples. Finally, by holding the pull rod 2051 to drive the baffle 205 to move and open the discharge port 204, multiple sets of coating samples in the temporary storage cavity 202 can be discharged. This facilitates the continuous clamping of multiple sets of coating samples, improves the testing efficiency, and eliminates the need for frequent opening and closing of the furnace door, thus avoiding affecting the heat treatment effect of the coating sample block and ensuring the accuracy of subsequent testing.
