[0002] A pull-out force test fixture is a special tool used to measure the pull-out force of materials or components. It has the following functions:

[0003] Accurately measure pull-out force: Ensure accurate quantification of the pull-out force on materials or components, providing reliable data for product quality assessment and engineering design;

[0004] Standardized testing: enables unified and standardized pull-out force testing of different batches of products or under different test conditions to ensure comparability of test results;

[0005] Improve test efficiency: Specially designed fixtures can quickly and conveniently perform pull-out force tests, reducing test time and labor costs.

[0006] In modern industrial production and scientific research, it is crucial to accurately test the pull-out force of materials. Traditional pull-out force test fixtures are often difficult to adjust, which to a certain extent limits the efficiency and accuracy of the test. Different materials and products require different pull-out force test conditions, which requires the test fixture to be easily adjusted to meet different test needs. However, the existing method for testing pull-out force is to place the measured object at a certain position for limiting, and then use a pull-out force testing machine to measure whether the pull-out force is qualified. However, the volumes of the measured objects are different, so different limiters need to be frequently replaced, which not only increases the workload of the testers, but also reduces the measurement efficiency of the pull-out force testing machine. Therefore, an easily adjustable pull-out force test fixture is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

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

[0033] Reference Figure 1-5 The utility model provides an embodiment: it includes a mounting base 1, a pulling force measuring body 2 is fixedly installed on the top of the mounting base 1, an L-shaped plate 3 is slidably installed on the top of the mounting base 1, and a mounting plate 4 is fixedly installed on the top of the mounting base 1. A connecting plate 5 is provided on the right side of the L-shaped plate 3, and the left side of the connecting plate 5 contacts the right side of the L-shaped plate 3. Adjustment slots 6 are provided on the right side of the L-shaped plate 3 and the left side of the connecting plate 5. A limiting component 7 for limiting the measuring object is provided inside the adjusting slot 6. When the pulling force of the object needs to be detected, the object can be placed inside the L-shaped plate 3, and then the L-shaped plate 3 and the mounting plate 4 can be pushed to one side at the same time. When the L-shaped plate 3 and the mounting plate 4 clamp the object, the object can be limited by the limiting component 7, and finally the pulling force measuring body 2 can be started to detect the pulling force of the object.

[0034] Reference Figure 1-5 The locking cam 75 is fixed on the top of the adjusting screw 6, and the locking cam 76 is fixed on the top of the adjusting screw 6, so that the locking cam 76 is locked and the locking cam 76 is locked. The first bevel gear 74 and the second bevel gear 75 are meshed with each other, and the rotation of the rotating rod 73 can drive the first bevel gear 74 to rotate, and the rotation of the first bevel gear 74 drives the second bevel gear 75 to rotate. Since the threads of each two sets of screw rods 71 are opposite, the rotation of the second bevel gear 75 drives the screw rod 71 to rotate, and the rotation of the screw rod 71 drives the screw block 72 to move toward the bottom. The movement of the screw block 72 to the bottom can limit the object to be tested. The front end of the rotating rod 73 passes through the front side of the connecting plate 5 and the L-shaped plate 3. The front side of the rotating rod 73 is fixedly installed with a rotating disk 8. The rotating rod 73 is rotatably mounted with the rotating rod 73 and the L-shaped plate 3. By setting the rotating disk 8, the contact area when the rotating rod 73 is rotated can be increased, thereby improving the efficiency of the rotating rod 73.

[0035] Reference Figure 1-5, the front side of the mounting plate 4 is rotatably installed with a transmission gear 9, and the front side of the mounting plate 4 is provided with two groups of tooth plates 10, which mesh with the transmission gear 9, and the front side of the tooth plate 10 is fixedly installed with a connecting block 11, wherein the front side of one group of connecting blocks 11 is fixedly installed on the back side of the L-shaped plate 3, and the front side of the other group of connecting blocks 11 is fixedly installed on the back side of the mounting plate 4. Through the cooperation of the transmission gear 9, the tooth plate 10 and the connecting block 11, when the L-shaped plate 3 is pulled or pushed, the L-shaped plate 3 will drive one group of connecting blocks 11 and the tooth plate 10 to move, and the movement of the tooth plate 10 drives the transmission gear 9 to rotate, and the rotation of the transmission gear 9 drives the other group of tooth plates 10 and the connecting block 11 to move. Thereby, the spacing between the L-shaped plate 3 and the mounting plate 4 can be adjusted. The bottom of the mounting plate 4 and the bottom of the L-shaped plate 3 are fixedly installed with a stabilizing block 12. The top of the mounting seat 1 is provided with a stabilizing groove 13. The stabilizing block 12 and the stabilizing groove 13 are slidably installed. Through the mutual cooperation of the stabilizing block 12 and the stabilizing groove 13, the stability of the L-shaped plate 3 and the mounting plate 4 can be ensured during movement, thereby preventing the L-shaped plate 3 and the mounting plate 4 from shaking during movement. A rubber pad 14 is provided at the bottom of the screw block 72, and the top of the screw block 72 is detachably installed by a bolt and the rubber pad 14. Through the setting of the rubber pad 14, the object to be detected can be limited to prevent the screw block 72 from pinching the detected object.

[0036] Working principle: When it is necessary to detect the pulling force of an object, the object can be placed inside the L-shaped plate 3, and then the L-shaped plate 3 can be pushed to drive one group of connecting blocks 11 and the tooth plate 10 to move. The movement of the tooth plate 10 drives the transmission gear 9 to rotate, and the rotation of the transmission gear 9 drives the other group of tooth plates 10 and the connecting block 11 to move. When the L-shaped plate 3 and the mounting plate 4 limit the detection object, the rotating disk 8 can be rotated at this time. The rotation of the rotating disk 8 drives the rotating rod 73 to rotate, and the rotation of the rotating rod 73 drives the first bevel gear 74 to rotate. The rotation of the first bevel gear 74 drives the second bevel gear 75 to rotate. Since the threads of each two groups of screw rods 71 are opposite, the rotation of the second bevel gear 75 drives the screw rod 71 to rotate. The rotation of the screw 71 drives the screw block 72 to move to the bottom. The movement of the screw block 72 to the bottom can limit the object to be tested, and then the pulling force measuring body 2 can be started to perform pulling force detection on the object.

[0037] 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 replacements for some of the technical features therein.
