[0002] Penetrant testing is widely used in general industry, shipbuilding industry, weapons industry, nuclear industry, aerospace and other fields. It is an important means of surface quality control. The reliability of penetrant testing has become an important guarantee for product quality reliability. The effect of penetrant testing depends on the performance of the flaw detection agent and the correctness of the flaw detection process and operation. These can only be objectively evaluated by testing certain penetration test blocks.

[0003] After searching, Chinese patent announcement number: CN207992007U discloses a penetration test block rack. The device includes: a main body, the main body is a rectangular plate-like structure, a test block groove is arranged in the middle of the upper part, and the inner wall and bottom of the groove are attached with a silicone protective pad; a suspension part is also provided on one side of the main body, and the suspension part is provided with a through groove. The beneficial effects of the utility model are: the device is simple to manufacture, convenient and quick to operate, and can be used for various detection methods. There is no need to hold the test block in the whole detection process, which avoids secondary contamination caused by direct contact with the test block with hands, and also avoids damage to the test block caused by accidents such as test block falling off, which better guarantees the reliability of the test block detection results in performance testing and system verification, and has good economic value and social value.

[0004] The above-mentioned technical patent can place the penetration test block when in use, which makes the detection more convenient to a certain extent. However, the test block is only naturally placed on the test block slot without any additional structure. This will result in insufficient sealing between the test block and the test block rack when the test block is tested, causing the tested liquid to flow out from the gap between the test block and the test block rack, which will cause the test result to be insufficiently accurate. Therefore, a penetration test block rack is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a penetration test block rack, which aims to improve the problem in the prior art that the connection between the test block and the test block rack is not sufficiently sealed, resulting in inaccurate test results.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a penetration test block rack, comprising an outer shell, a protective pad fixedly connected to the middle of the outer shell, through grooves are provided in the protective pad and the middle of the outer shell, a gear is rotatably connected to one side of the outer shell, a connecting rod is slidably connected to the inside of the outer shell, an end of the connecting rod close to the gear is fixedly connected to a rack, the rack and the gear are meshed with each other, a clamping block is fixedly connected to the other end of the connecting rod, a spring is fixedly connected to the outside of the clamping block, an angle is provided at the bottom of the clamping block away from the spring, a sealing assembly is fixedly connected to the inside of the protective pad, and a lifting assembly is installed at the bottom of the outer shell.

[0008] Furthermore, the sealing assembly includes a plurality of sealing rings, and the plurality of sealing rings are fixedly connected to the inner wall of the protection pad.

[0009] Through the above technical solution, the sealing ring will be deformed when the test block is placed in the middle of the protective pad, thereby improving the seal between the test block and the side wall of the protective pad, thereby further improving the accuracy of the test data.

[0010] Furthermore, the sealing assembly comprises a rubber sealing sheet, and the rubber sealing sheet is fixedly connected to the inner wall of the protection pad.

[0011] Through the above technical solution, the rubber sealing sheet will deform when the test block is placed in the middle of the protective pad, thereby improving the seal between the test block and the side wall of the protective pad, thereby further improving the accuracy of the test data.

[0012] Furthermore, the sealing assembly comprises a rubber sealing sheet and a sealing ring, wherein the rubber sealing sheet and the sealing ring are both fixedly connected to the inner side wall of the protection pad, and the rubber sealing sheet is located above the sealing ring.

[0013] Through the above technical solution, the sealing ring and the rubber sealing sheet will be deformed when the test block is placed in the middle of the protective pad, thereby improving the seal between the test block and the side wall of the protective pad, thereby further improving the accuracy of the test data.

[0016] Furthermore, a knob is rotatably connected to the outer side of the shell, and the gear is fixedly connected to one end of the knob.

[0017] By means of the above technical solution, the gears can be rotated more conveniently.

[0018] Furthermore, one end of the spring away from the clamping block is fixedly connected to the inner side of the shell, a notch is provided on the upper part of the shell, and the clamping block is slidably connected to the middle of the notch.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1:

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a penetration test block rack, including a shell 1, a protective pad 2 is fixedly connected to the middle of the shell 1, and a through groove 3 is provided in the middle of the protective pad 2 and the shell 1. The liquid to be tested will flow out from the middle of the through groove 3 after passing through the test block. A gear 5 is rotatably connected to one side of the shell 1, and a connecting rod 6 is slidably connected to the inside of the shell 1. A rack 8 is fixedly connected to one end of the connecting rod 6 close to the gear 5, and the rack 8 and the gear 5 are meshed with each other. There are two racks 8, which are respectively located on the upper and lower sides of the gear 5. When the gear 5 rotates, the two racks 8 can move in opposite directions. The other end of the connecting rod 6 is fixedly connected to a clamp 7. When the rack 8 moves outward, it can drive the clamp 7 to move outward synchronously. At this time, the test block can be placed in the middle of the protective pad 2 for testing.

[0035] A spring 9 is fixedly connected to the outside of the clamp 7. The end of the spring 9 away from the clamp 7 is fixedly connected to the inside of the housing 1. The bottom of the clamp 7 away from the spring 9 is provided with an angled angle. After the test block is placed in the middle of the protective pad 2, the knob 4 is loosened. Under the action of the spring 9, the clamp 7 can be moved toward the middle. When the angled angle at the bottom of the clamp 7 contacts the test block, a downward force is generated on the test block under the action of the inclined surface, thereby increasing the sealing between the protective pad 2 and the test block, thereby improving the accuracy of the data during the test block detection. The outer side of the housing 1 is rotatably connected to a knob 4. The gear 5 is fixedly connected to one end of the knob 4. The gear 5 can be rotated more conveniently by using the knob 4.

[0036] Reference Figure 1-Figure 3 A notch 10 is provided on the upper part of the housing 1, and the clamp 7 is slidably connected in the middle of the notch 10. The clamp 7 is placed and its position is restricted by the notch 10, so that the movement of the clamp 7 is smoother. A sealing assembly is fixedly connected to the inside of the protective pad 2, and the sealing assembly includes a plurality of sealing rings 11, and the plurality of sealing rings 11 are fixedly connected to the inner wall of the protective pad 2. When the test block is placed into the middle of the protective pad 2, it will first contact the sealing ring 11, thereby deforming the sealing ring 11, thereby increasing the sealing between the test block and the inner side of the protective pad 2, which can further improve the accuracy of the test block detection data.

[0037] Reference Figure 2-Figure 4 A lifting assembly is installed at the bottom of the shell 1, and the lifting assembly includes an inner frame 13, the inner frame 13 is slidably connected to the middle part of the through groove 3, a connecting block 14 is fixedly connected to the outside of the inner frame 13, and a tension spring 15 is fixedly connected to the top of the connecting block 14, and the other end of the tension spring 15 is fixedly connected to the bottom of the shell 1. When the test block is detected and needs to be taken out, the knob 4 can be turned again to make the clamping block 7 move to both sides again. At this time, under the action of the tension spring 15, the connecting block 14 and the inner frame 13 can be moved upward, and the bottom of the test block can be lifted up, so that the test block is separated from the protective pad 2, so as to facilitate the removal of the test block. A plurality of support pads 16 are fixedly connected to the top of the shell 1, and the inner frame 13 is located between the plurality of support pads 16. The friction between the penetration test block rack and the working surface is increased by the support pads 16, and the distance between the shell 1 and the working surface is increased at the same time, which facilitates the work of the tension spring 15.

[0038] Embodiment 2:

[0039] Reference Figure 5Different from the above-mentioned embodiment, the utility model provides another embodiment: on the basis of the first embodiment, the sealing component is replaced with a rubber sealing sheet 12, and the rubber sealing sheet 12 is fixedly connected to the inner wall of the protective pad 2. When the test block is placed in the middle of the protective pad 2, it will first contact the rubber sealing sheet 12, so that the rubber sealing sheet 12 is deformed, thereby increasing the sealing between the test block and the inner side of the protective pad 2, which can further improve the accuracy of the test block detection data.

[0040] Embodiment three:

[0041] Reference Figure 5 Different from the above-mentioned embodiment, the utility model provides another embodiment: on the basis of the first embodiment, the sealing component is replaced with a rubber sealing sheet 12 and a sealing ring 11, and the rubber sealing sheet 12 and the sealing ring 11 are fixedly connected to the inner wall of the protective pad 2, and the rubber sealing sheet 12 is located above the sealing ring 11. When the test block is placed in the middle of the protective pad 2, it will first contact the rubber sealing sheet 12, and then contact the sealing ring 11, so that the rubber sealing sheet 12 and the sealing ring 11 are deformed, thereby increasing the sealing between the test block and the inner side of the protective pad 2, which can further improve the accuracy of the test block detection data.

[0042] Working principle: When using the penetration test block rack, first turn the knob 4 to rotate the gear 5. Under the action of the rack 8, push the two connecting rods 6 outward, so that the clamp 7 moves to both sides. At this time, place the test block to be tested in the middle of the protective pad 2, loosen the knob 4, and move the clamp 7 toward the middle under the action of the spring 9. When the bottom bevel of the clamp 7 contacts the test block, a downward force is generated on the test block under the action of the inclined surface, which causes the protective pad 2 to deform, thereby increasing the sealing between the test block and the protective pad 2, thereby improving the accuracy of the test block test data. When the test block is placed in the middle of the protective pad 2, the test block will first contact the rubber sealing sheet 12 or the inner frame 13, thereby causing the rubber sealing sheet 12 or the inner frame 13 to deform, thereby improving the sealing between the test block and the edge of the protective pad 2, thereby further improving the accuracy of the test block test results.

[0043] When the test block needs to be taken out after the test is completed, the knob 4 can be turned again to move the clamping block 7 to both sides again. When the clamping block 7 is separated from the upper surface of the test block, the tension spring 15 will contract under the action of its own properties, thereby driving the connecting block 14 and the inner frame 13 to move upward, and the inner frame 13 passes through the middle of the through groove 3. When the inner frame 13 moves upward, the inner frame 13 will contact the bottom of the test block to drive the test block to move upward and push the test block out from the middle of the protective pad 2, so that the test block can be taken more conveniently and is more convenient to use.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
