Description

Technical Field

[0001] This utility model relates to the field of performance testing, specifically a tensile testing level adjustment frame. Background Technology

[0002] Within the elastic limit, the deformation of an object under the action of external force is proportional to the external force. For long objects whose length is much greater than their width and thickness, it is necessary to mark their deformation tensile force and support strength to make them safer during use.

[0003] Chinese invention patent CN103398900A, published on November 20, 2013, discloses a lever-type tensile testing bench. It mainly consists of a frame structure comprising a column, a top beam, a bottom beam, an upper support, a lower support, a jack, and a direct-reading hydraulic sensor. The column is located on one side of the structure, while the jack and the direct-reading hydraulic sensor are located on the other side. Several pin holes of equal center height are provided in the middle section of the top and bottom beams to fix specimens with different tensile strengths. During testing, the jack pushes the top beam, subjecting the tested material to tension, and the tensile force value of the tested material is obtained through the direct-reading hydraulic sensor placed under the jack. This invention has a simple structure, is easy to install, and its testing accuracy meets the requirements of construction sites. It saves manpower and resources and facilitates on-site management.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing test bench has a low adjustment height range, and because it is suitable for a narrow range of test object lengths, many long objects cannot be tested, which makes it impossible to adapt to more types of objects for testing. For example, when testing the structural performance of a ladder, it cannot be raised to a sufficient height for tensile testing. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing test benches have a low adjustment height range, which is due to the narrow range of lengths of the objects they can accommodate. This makes it impossible to test many types of objects, such as ladders, which cannot be raised to a sufficient height for tensile testing. The invention provides a tensile testing level adjustment frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a tensile testing horizontal adjustment frame, comprising a horizontal support plate, a first square tube, and a reinforcing support rod; the reinforcing support rod is symmetrically fixed to the upper surface of the horizontal support plate; the first square tube is fixed between the reinforcing support rod and the horizontal support plate; a second square tube is slidably inserted into the upper end of the first square tube; multiple adjustment holes are provided through the sides of the first and second square tubes; adjustment sleeves are slidably sleeved on the first and second square tubes; a first fastener is inserted into the corresponding adjustment hole on the adjustment sleeve; a snap-fit ​​groove is provided on the adjustment sleeve; a horizontal placement plate is inserted into the snap-fit ​​groove; and a third fastener is inserted into the adjustment hole.

[0008] Furthermore, a second fastener is threadedly inserted into the corresponding opening on the horizontally placed plate of the adjusting sleeve.

[0009] Furthermore, a plurality of casters are fixed to the lower surface of the horizontal support plate.

[0010] Furthermore, the horizontal support plate is symmetrically sleeved on the adjusting sleeve.

[0011] Furthermore, the first square tube and the second square tube are of the same length.

[0012] The tensile testing level adjustment frame provided by this utility model has the following beneficial effects:

[0013] 1. This utility model can change the friction between the first square tube and the second square tube by rotating the third fastener, thereby adjusting the overlap distance between the first square tube and the second square tube and fixing them. There are two ways to fix the adjusting sleeve by rotating the first fastener: one is to insert it into the adjusting hole on the first square tube, and the other is to directly press it against the outer surface of the first square tube to fix it and adjust the height of the adjusting sleeve. After adjusting it to the test height above the ground, the horizontal placement plate is symmetrically placed in the two buckle slots. The distance between the two buckle slots is adjusted to meet the test requirements of one meter, two meters or three meters. Then the tensile testing machine is connected to the horizontal placement plate to conduct tensile testing, which solves the problem that the adjustment frame of the existing tensile testing is inconvenient to adjust.

[0014] 2. This utility model can stably fix the horizontal placement plate to the adjustment sleeve by rotating the second fastener to press it. Therefore, when it is necessary to adjust the height of the adjustment sleeve, simply loosen the two first fasteners to move the horizontal placement plate and the adjustment sleeve up and down simultaneously, making the height adjustment more convenient and quick, and solving the problem of inconvenient adjustment of existing adjustment frames.

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0023] Please see Figure 1-3As shown, a tensile testing horizontal adjustment frame includes a horizontal support plate 1, a first square tube 2, and a reinforcing support rod 3; the reinforcing support rod 3 is symmetrically fixed to the upper surface of the horizontal support plate 1; the first square tube 2 is fixed between the reinforcing support rod 3 and the horizontal support plate 1; a second square tube 4 is slidably inserted into the upper end of the first square tube 2; multiple adjustment holes 5 are opened through the sides of the first square tube 2 and the second square tube 4; adjustment sleeves 6 are slidably sleeved on the first square tube 2 and the second square tube 4; a first fastener 7 is inserted into the adjustment sleeve 6 corresponding to the adjustment hole 5; a snap-fit ​​groove 8 is opened on the adjustment sleeve 6; a horizontal placement plate 9 is inserted into the snap-fit ​​groove 8; a third fastener 12 is inserted into the adjustment hole 5; during operation, by rotating... The third fastener 12 can change the friction between the first square tube 2 and the second square tube 4, thereby adjusting the overlap distance between the first square tube 2 and the second square tube 4 before fixing. There are two ways to fix the adjusting sleeve 6 by rotating the first fastener 7: one is to insert it into the adjusting hole 5 on the first square tube 2, and the other is to directly press it against the outer surface of the first square tube 2 to fix it and adjust the height of the adjusting sleeve 6. After adjusting it to the test height above the ground, the horizontal placement plate 9 is symmetrically placed in the two buckle slots 8. The distance between the two buckle slots 8 is adjusted to meet the test requirements of one meter, two meters or three meters. Then the tensile testing machine is connected to the horizontal placement plate 9 to conduct the tensile test, which solves the problem that the existing tensile testing adjustment frame is inconvenient to adjust.

[0024] The adjusting sleeve 6 has a corresponding hole for the horizontal placement plate 9, with a second fastener 10 threadedly inserted. During operation, by rotating the second fastener 10 to press the horizontal placement plate 9, the horizontal placement plate 9 can be stably fixed on the adjusting sleeve 6. Thus, when the height of the adjusting sleeve 6 needs to be adjusted, only the two first fasteners 7 need to be loosened, and the height of the horizontal placement plate 9 and the adjusting sleeve 6 can be moved up and down synchronously to change the height, making the height adjustment more convenient and quick, and solving the problem of inconvenient adjustment of the existing adjusting frame.

[0025] The lower surface of the horizontal support plate 1 is fixed with multiple casters 11. During operation, the multiple casters 11 fixed to the lower surface of the horizontal support plate 1 make it easy for the adjustment frame to move and change its angle and position, thus solving the problem that the existing adjustment frame is inconvenient to move and adjust its angle.

[0026] The horizontal placement plate 9 is symmetrically sleeved on the adjustment sleeve 6. During operation, the center position of the horizontal placement plate 9 can be tested by the symmetrically placed horizontal placement plate 9 to test the structural strength and deformation distance of the horizontal placement plate 9, thereby ensuring the correct structural design, achieving the required performance, and ensuring that the product performance meets the standards. This solves the problem of inconvenient performance testing of existing materials and other objects.

[0027] The first square tube 2 and the second square tube 4 have the same length. During operation, by ensuring that the first square tube 2 and the second square tube 4 have the same length, the precise adjustment position of the adjustment hole 5 within the total length range of the telescopic length can be determined as an integer multiple of the spacing between the adjustment holes 5. This solves the problem of the existing support frame having an inconvenient height adjustment range.

[0028] By adopting the above scheme, when this utility model is in use, the spacing of the adjustment holes 5 is designed to be ten centimeters, and the distance from the ground is also an integer multiple of ten centimeters, so that it can coincide with the height of one meter and two meters of the conventional tensile test height, so that the commonly used position can be accurately fixed by using the adjustment holes 5.

[0029] By rotating the third fastener 12, the friction between the first square tube 2 and the second square tube 4 can be changed, thereby adjusting the overlap distance between the first square tube 2 and the second square tube 4 before fixing. There are two ways to fix the adjusting sleeve 6 by rotating the first fastener 7: one is to insert it into the adjusting hole 5 on the first square tube 2, and the other is to directly press it against the outer surface of the first square tube 2 to adjust the height of the adjusting sleeve 6. After adjusting to the test height above the ground, the horizontal placement plate 9 is symmetrically placed in the two snap-fit ​​slots 8. The distance between the two snap-fit ​​slots 8 is adjusted to meet the test requirements of one meter, two meters, or three meters. Then, the tensile testing machine is connected to the horizontal placement plate 9 for tensile testing, solving the problem of inconvenient adjustment of the existing tensile testing adjustment frame. By rotating the second fastener 10 to press the horizontal placement plate 9, the horizontal placement plate 9 can be stably fixed on the adjusting sleeve 6. Therefore, when the height of the adjusting sleeve 6 needs to be adjusted, only the two first fasteners 7 need to be loosened. The vertical movement of the step changes the height of the horizontal placement plate 9 and the adjusting sleeve 6, making height adjustment more convenient and quick, solving the problem of inconvenient adjustment of existing adjustment frames; by fixing multiple universal wheels 11 to the lower surface of the horizontal support plate 1, this adjustment frame can be easily moved to change angle and position, solving the problem of inconvenient movement and angle adjustment of existing adjustment frames; by symmetrically placing the horizontal placement plates 9, a tensile test can be performed on the center position of the horizontal placement plates 9 to test the structural strength and deformation distance of the horizontal placement plates 9, thereby ensuring the correctness of the structural design, achieving the required performance, and ensuring that the product performance meets the standards, solving the problem of inconvenient performance testing of existing materials and other objects; by using the fact that the first square tube 2 and the second square tube 4 are of the same length, the precise adjustment position of the adjustment hole 5 within the total length range of the entire telescopic length can be determined as an integer multiple of the spacing between the first square tube 2 and the second square tube 4, solving the problem of inconvenient height adjustment range of existing support frames.
