Description

Technical Field

[0001] This utility model belongs to the field of adhesive testing technology, specifically, it relates to a structural adhesive bonding strength pull-out test device. Background Technology

[0002] Structural adhesives are high-performance adhesives mainly used in construction, automotive, aerospace and other fields to bond and fix various materials such as metals, plastics, glass, ceramics and composite materials. Compared with ordinary glues, structural adhesives have higher strength, durability and resistance to environmental factors.

[0003] The structural adhesive bond strength pull-out tester is a professional device used to test the bond strength of structural adhesives. It mainly measures the bond strength between materials by applying tensile force, evaluates the bonding performance, and ensures product quality and project safety.

[0004] Patent CN216449315U discloses a device for testing the tensile shear strength of structural adhesives, which allows the pressure plate assembly to be adjusted within a certain range according to the thickness of the adhesive plate, further improving the applicability of the device. Although the device can test the strength of structural adhesives, in actual use, when other tests are needed after the structural adhesive test is completed, the adhesive plate still has residual structural adhesive, so the used adhesive plate needs to be removed and replaced with a new one. When removing or replacing the adhesive plate, the position of the L-shaped tension frame and the L-shaped tension clamp needs to be repeatedly adjusted, which is cumbersome and reduces the testing efficiency. Utility Model Content

[0005] To address the technical problem of cumbersome position adjustment of L-shaped tension frames and L-shaped tension clamps, which reduces testing efficiency, this utility model provides a structural adhesive bonding strength pull-out test device.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A structural adhesive bond strength pull-out test device includes a bracket; a cylinder connected above the bracket; a first mounting shell connected to the output end of the cylinder, a first test plate slidably connected inside the first mounting shell, first outer shells connected to the openings on both sides of the first mounting shell corresponding to the positions of the first test plate, a first stop block slidably connected inside the first outer shell, and symmetrically arranged first springs connecting the first stop block and the first outer shell; a second test plate is disposed below the first test plate, a second mounting shell is disposed below the second test plate, the second test plate slidably connected inside the second mounting shell, a second outer shell connected to the side opening of the second mounting shell corresponding to the position of the second test plate, a second stop block slidably connected inside the second outer shell, and symmetrically arranged second springs connecting the second stop block and the second outer shell.

[0008] Preferably, a first lever is connected above the side of the first stop away from the first detection plate, and a first movable groove is opened on the first mounting shell corresponding to the position of the first lever, and the first lever is slidably connected in the first movable groove; a second lever is connected above the side of the second stop away from the second detection plate, and a second movable groove is opened on the second mounting shell corresponding to the position of the second lever, and the second lever is slidably connected in the second movable groove.

[0009] Preferably, a through first groove is provided below the first mounting shell. The first groove is convex in shape, and the first detection plate is in the shape of an "I". The top of the first detection plate is slidably connected in the first groove.

[0010] A second sliding groove is provided on the top of the second mounting shell. The second sliding groove is convex in shape. The second detection plate is in the shape of an "I". The bottom of the second detection plate is slidably connected in the second sliding groove.

[0011] Preferably, the width of the lower part of the first detection plate is greater than the width of the first mounting shell.

[0012] Preferably, the first stop block is attached to the upper side of the first detection plate, and the second stop block is attached to the lower side of the second detection plate.

[0013] Preferably, a first fixing rod is provided on both sides of the second mounting shell near the second outer shell, and the second mounting shell is rotatably connected between the first fixing rods; a second fixing rod is provided on both sides of the second mounting shell away from the second outer shell, and the second mounting shell is located between the second fixing rods.

[0014] Preferably, the first fixing rod is positioned away from the first detection plate.

[0015] Preferably, a first slot is provided above the second fixing rod and at one end of the second mounting shell corresponding to the second fixing rod, and a plug rod is inserted into the first slot; a second slot is provided below the first fixing rod, and the second slot is located at the position corresponding to the first slot after the second mounting shell is rotated 90°.

[0016] Preferably, a threaded ring is connected to the insertion rod at the position corresponding to one of the second fixing rods, and a first threaded hole is opened at the position corresponding to the threaded ring on one of the second fixing rods, with the threaded ring and the first threaded hole threadedly engaged.

[0017] Preferably, one of the first fixing rods has a second threaded hole at the position corresponding to the threaded ring, and the threaded ring is threadedly engaged with the second threaded hole.

[0018] The beneficial effects of this utility model are:

[0019] When installing the first detection plate, one of the first levers is moved upwards. The rising lever causes the first stop to rise, entering the first housing. During this process, the first stop compresses the first spring, causing it to contract and store restoring force. Once fully inside the housing, an opening in the first mounting shell is exposed. The first detection plate is then inserted into the first groove of the housing through this opening. After the plate is fully inside, the lever is slowly released. The first stop returns to its original position under the restoring force of the spring, preventing the plate from sliding out of the housing. When replacing the first detection plate after structural adhesive testing, one of the first levers is moved upwards, causing the first stop to enter the first housing. Once fully inside, an opening is exposed, allowing the plate to be removed. This process of installing and removing the first detection plate is simple, convenient, and efficient.

[0020] In practical use, when installing the second detection plate, one of the second levers is pushed down. The second lever descends, causing the second stop to descend as well. After the second stop descends, it enters the second housing. During this process, the second stop compresses the second spring, which then contracts and stores its restoring force. Once the second stop is fully inside the second housing, the opening of the second mounting housing is exposed. At this point, the second detection plate is inserted from the opening into the second groove of the second mounting housing. After the second detection plate is fully inside the groove, the second lever is slowly released. Under the restoring force of the second spring, the second stop returns to its original position, blocking the second detection plate and preventing it from sliding out of the second mounting housing. When the second detection plate needs to be replaced after the structural adhesive test is completed, one of the second levers is pushed down, causing the first stop to enter the first housing. Once the first stop is fully inside the first housing, an opening is exposed, allowing the first detection plate to be removed from the first mounting housing. This process of installing and removing the first detection plate is simple and convenient, improving efficiency.

[0021] When testing the tensile strength of the structural adhesive, the second mounting shell is kept horizontal. The first slot on the second mounting shell is aligned with the first slot on the second fixing rod. After alignment, the insert rod is inserted into the first slot of the second fixing rod and the second mounting shell. After insertion, the handle is rotated to rotate the rod, causing the threaded ring to enter the first threaded hole and fix the insert rod. After the second mounting shell and the insert rod are fixed, the tensile strength of the structural adhesive can be tested. When testing the shear strength of the structural adhesive, the handle is rotated to rotate the insert rod, causing the threaded ring to move out of the first threaded hole. After removal, the insert rod is removed from the first slot of the second fixing rod and the second mounting shell. After the second mounting shell is removed, the end furthest from the second outer shell is no longer fixed. Rotate the second mounting shell 90° to align it with the first fixing rod. Then, insert the insertion rod into the second slot of the first fixing rod and the first slot of the second mounting shell. After insertion, rotate the handle to allow the threaded ring to enter the second threaded hole and fix the insertion rod. After the second mounting shell and the insertion rod are fixed, connect the test block to the side of the second test plate near the first test plate with structural adhesive. This allows for shear strength testing of the structural adhesive, enabling both tensile strength testing and shear strength testing. This increases the functionality and adaptability of the device.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1 - Figure 6 As shown, a structural adhesive bonding strength pull-out test device includes a bracket 1, with a cylinder 11 connected above the bracket 1. The cylinder 11 is used to test the tensile strength and shear strength of the structural adhesive.

[0038] The output end of the cylinder 11 is connected to a first mounting shell 12, and a first detection plate 13 is slidably connected inside the first mounting shell 12. The first detection plate 13 can be installed by cooperating with the first mounting shell 12.

[0039] A through first groove 2 is provided below the first mounting shell 12. The first groove 2 is convex in shape. The first detection plate 13 is in the shape of an "I". The first detection plate 13 is slidably connected to the first groove 2. This arrangement can fix the position of the first detection plate 13 and strengthen the strength between the first detection plate 13 and the first mounting shell 12, making it easier to test the structural adhesive.

[0040] The width of the first testing plate 13 below is greater than the width of the first mounting shell 12. With this setting, the first mounting shell 12 can be avoided from affecting the shear strength test of the structural adhesive.

[0041] The first housing 3 is connected to the openings on both sides of the first mounting housing 12 at the positions corresponding to the first detection plate 13. The first block 31 is slidably connected inside the first housing 3. The first block 31 is used to block the first detection plate 13 and prevent the first detection plate 13 from sliding out of the first mounting housing 12.

[0042] The first stop 31 is attached to the upper side of the first detection plate 13. With this arrangement, the first stop 31 can block the first detection plate 13 without affecting the detection.

[0043] A first spring 32 is symmetrically arranged between the first stop block 31 and the first outer shell 3. The first spring 32 is used to reset the first stop block 31.

[0044] A first stop block 33 is connected above the side of the first stop block 31 away from the first detection plate 13. The first stop block 33 is used to send the first stop block 31 into the first housing 3.

[0045] The first mounting shell 12 has a first movable groove 34 at the position corresponding to the first lever 33. The first lever 33 is slidably connected in the first movable groove 34. By opening the first movable groove 34, it can be ensured that the first lever 33 sends the first stop 31 into the first outer shell 3.

[0046] In practical use, when installing the first detection plate 13, one of the first levers 33 is pushed upwards. The first lever 33 rises, causing the first stop 31 to rise. After the first stop 31 rises, it enters the first housing 3. During the process of the first stop 31 entering the first housing 3, it will compress the first spring 32. After being compressed, the first spring 32 will contract and store the restoring force. After the first stop 31 is fully entered into the first housing 3, an opening of the first mounting shell 12 is exposed. At this time, the first detection plate 13 is sent into the first slide groove 2 of the first mounting shell 12 from the opening. After the first detection plate 13 is fully entered into the first slide groove 2, the first lever 33 is slowly released. Under the action of the restoring force of the first spring 32, the first stop 31 will reset and block the first detection plate 13 to prevent the first detection plate 13 from sliding out of the first mounting shell 12.

[0047] After the structural adhesive test is completed, when the first test plate 13 needs to be replaced, one of the first levers 33 is pushed upwards to allow the first stop 31 to enter the first housing 3. After the first stop 31 is fully inside the first housing 3, an opening will be exposed. At this time, the first test plate 13 can be removed from the first mounting housing 12. The installation and removal of the first test plate 13 is relatively simple and convenient, which can improve efficiency.

[0048] A second testing plate 14 is provided below the first testing plate 13. The first testing plate 13 and the second testing plate 14 cooperate to test the tensile strength and shear strength of the structural adhesive.

[0049] A second mounting shell 15 is provided below the second detection plate 14. The second detection plate 14 is slidably connected inside the second mounting shell 15. The second detection plate 14 can be installed by cooperating with the second mounting shell 15.

[0050] A second sliding groove 21 is provided above the second mounting shell 15. The second sliding groove 21 is convex in shape, and the second detection plate 14 is in the shape of an "I". The second detection plate 14 is slidably connected to the second sliding groove 21 below. This arrangement can fix the position of the second detection plate 14 and strengthen the strength between the second detection plate 14 and the second mounting shell 15, making it easier to test the structural adhesive.

[0051] A second outer shell 4 is connected to the side opening of the second mounting shell 15 at the position corresponding to the second detection plate 14. A second stop 41 is slidably connected inside the second outer shell 4. The second stop 41 is used to block the second detection plate 14 and prevent the second detection plate 14 from sliding out of the second mounting shell 15.

[0052] The second stop 41 is attached to the lower side of the second detection plate 14. With this arrangement, the second stop 41 can block the second detection plate 14 without affecting the detection.

[0053] A symmetrically arranged second spring 42 is connected between the second stop 41 and the second housing 4. The second spring 42 is used to reset the second stop 41.

[0054] A second stop block 43 is connected above the side of the second stop block 41 away from the second detection plate 14. The second stop block 43 is used to send the second stop block 41 into the second housing 4.

[0055] The second mounting shell 15 has a second movable groove 44 at the position corresponding to the second lever 43. The second lever 43 is slidably connected in the second movable groove 44. By opening the second movable groove 44, it can be ensured that the second lever 43 sends the second stop 41 into the second outer shell 4.

[0056] In practical use, when installing the second detection plate 14, one of the second levers 43 is pushed down. The second lever 43 descends, causing the second stop 41 to descend as well. After descending, the second stop 41 enters the second housing 4. During the process of the second stop 41 entering the second housing 4, it will compress the second spring 42. After being compressed, the second spring 42 will contract and store restoring force. After the second stop 41 is fully inside the second housing 4, the opening of the second mounting shell 15 is exposed. At this time, the second detection plate 14 is sent from the opening into the second slide groove 21 of the second mounting shell 15. After the second detection plate 14 is fully inside the second slide groove 21, the second lever 43 is slowly released. Under the action of the restoring force of the second spring 42, the second stop 41 will reset and block the second detection plate 14, preventing the second detection plate 14 from sliding out of the second mounting shell 15.

[0057] After the structural adhesive test is completed, when the second test plate 14 needs to be replaced, one of the second levers 43 is pushed down to allow the first stop 31 to enter the first housing 3. After the first stop 31 is fully inside the first housing 3, an opening will be exposed. At this time, the first test plate 13 can be removed from the first mounting housing 12. The installation and removal of the first test plate 13 is relatively simple and convenient, which can improve efficiency.

[0058] The second mounting shell 15 is provided with first fixing rods 5 on both sides near the second outer shell 4. The second mounting shell 15 is rotatably connected between the first fixing rods 5, and the first fixing rods 5 are used to fix the position of the second mounting shell 15.

[0059] The first fixing rod 5 is positioned away from the first detection plate 13. This arrangement ensures that the first detection plate 13 will not come into contact with the second detection plate 14 during the descent of the first detection plate 13 when the shear strength of the structural adhesive is tested.

[0060] Second fixing rods 51 are provided on both sides of the second mounting shell 15 at positions away from the second outer shell 4. The second mounting shell 15 is located between the second fixing rods 51, and the second fixing rods 51 are used to fix the position of the second mounting shell 15.

[0061] A first slot 54 is provided above the second fixing rod 51 and at one end of the second mounting shell 15 corresponding to the second fixing rod 51. A plug rod 52 is inserted into the first slot 54. The plug rod 52 is used to fix the second mounting shell 15 and prevent the second mounting shell 15 from rotating at will.

[0062] One end of the insertion rod 52 is connected to a handle 53, which is used to rotate the insertion rod 52 so that the threaded ring 55 disengages from the first threaded hole 56 or the second threaded hole 58.

[0063] The insertion rod 52 is connected to a threaded ring 55 at the position corresponding to one of the second fixing rods 51. A first threaded hole 56 is opened at the position corresponding to the threaded ring 55 of one of the second fixing rods 51. The threaded ring 55 is threadedly engaged with the first threaded hole 56. The engagement of the threaded ring 55 with the first threaded hole 56 prevents the insertion rod 52 from sliding out of the second fixing rod 51 and the second mounting shell 15.

[0064] A second slot 57 is provided below the first fixing rod 5. The second slot 57 is located at the position corresponding to the first slot 54 after the second mounting shell 15 is rotated 90°. By providing the second slot 57, the position of the second mounting shell 15 can be fixed when the structural adhesive is tested for shear strength, preventing the second mounting shell 15 from rotating arbitrarily.

[0065] One of the first fixing rods 5 has a second threaded hole 58 at the position corresponding to the threaded ring 55. The threaded ring 55 is threadedly engaged with the second threaded hole 58. The engagement of the threaded ring 55 with the second threaded hole 58 prevents the insertion rod 52 from sliding out of the first fixing rod 5 and the second mounting shell 15.

[0066] In practical use, when testing the tensile strength of the structural adhesive, the second mounting shell 15 is placed in a horizontal position, and the first slot 54 on the second mounting shell 15 is aligned with the first slot 54 on the second fixing rod 51. After alignment, the insert rod 52 is inserted into the second fixing rod 51 and the first slot 54 of the second mounting shell 15. After insertion, the handle 53 is rotated to rotate the rod, so that the threaded ring 55 enters the first threaded hole 56 to fix the insert rod 52. After the second mounting shell 15 and the insert rod 52 are fixed, the tensile strength of the structural adhesive can be tested.

[0067] When testing the shear strength of structural adhesive, rotating the handle 53 causes the insertion rod 52 to rotate, causing the threaded ring 55 to move out of the first threaded hole 56. After moving out, the insertion rod 52 is moved out of the second fixing rod 51 and the first slot 54 of the second mounting shell 15. After moving out, the end of the second mounting shell 15 away from the second outer shell 4 is no longer fixed. The second mounting shell 15 is rotated 90° to align with the first fixing rod 5. After alignment, the insertion rod 52 is inserted into the second slot 57 of the first fixing rod 5 and the first slot 54 of the second mounting shell 15. After insertion, rotating the handle 53 causes the threaded ring 55 to enter the second threaded hole 58, fixing the insertion rod 52. After the second mounting shell 15 and the insertion rod 52 are fixed, the test block is connected to the second test plate 14 near the first test plate 13 through structural adhesive, and the shear strength of the structural adhesive can be tested. This device can test both the tensile strength and shear strength of the structural adhesive, increasing its functionality and improving its adaptability.
