Technical Field

[0001] This utility model belongs to the field of experimental chamber technology, specifically relating to a horizontal tensile testing device. Background Technology

[0002] There are various types of test chambers, and the horizontal tensile test chamber is one of them. The horizontal test chamber can generate environments with different high and low temperatures and humidity. At the same time, the horizontal chamber can be equipped with conventional pneumatic or electric driven tensile mechanisms to stretch metal materials to verify the properties of the metal. When stretching is not needed, the tensile mechanism can be manually disassembled. The main structure of the horizontal test chamber includes a support frame and the main body of the test chamber. The test chamber body mainly consists of an electrical control box and the test chamber. The electrical control box contains a water tank, a humidification tank, a compressor condenser, and other equipment required for testing. The object to be tested is placed inside the chamber of the test chamber and its performance is tested under the set temperature and humidity conditions. When horizontal test chambers are used to test columnar and tubular workpieces made of materials such as rubber and plastic, multiple columnar and tubular workpieces are stacked inside the test chamber. The overlapping between adjacent workpieces will affect the test and cause errors in the workpieces tested. The columnar and tubular workpieces inside the test chamber have overlapping parts, and multiple workpieces cannot be moved or their angles adjusted. Improvements are needed. Existing horizontal test chambers lack auxiliary suspension designs for adjusting the angle of multiple workpieces when testing columnar or tubular workpieces. To address this, this application proposes a horizontal tensile testing device. Utility Model Content

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5This utility model provides a technical solution: a horizontal tensile testing device, including a testing apparatus, comprising a support 1 and a horizontal tensile testing chamber 2. A door 21 is hinged to the surface of the horizontal tensile testing chamber 2. During testing, the workpiece is placed inside the cavity of the horizontal tensile testing chamber 2, the door 21 is closed, and the workpiece inside the horizontal tensile testing chamber 2 is subjected to performance testing under manual operation and with temperature and humidity set. The workpiece suspension assembly includes a fixing plate 3 fixed to the inner wall of the horizontal tensile testing chamber 2 by screws, a limiting cylinder 31 welded to the fixing plate 3, a crossbar 4 installed between opposing fixing plates 3, and a sleeve. The connecting piece 5 located on the outside of the crossbar 4, the adjusting rod 61 connected by a threaded screw, and the suspension tube 62 are used to suspend tubular or cylindrical workpieces. When placing these workpieces, both ends are passed through the suspension tube 62, allowing the workpieces to be suspended in mid-air. The workpieces are suspended with gaps between adjacent workpieces to prevent overlap. The inner diameter of the suspension tube 62 is slightly larger than the workpiece, making it suitable for suspending workpieces of different diameters within its inner diameter range. The insertion rod 41 at the end of the crossbar 4 and the limiting cylinder 31 are separate structures. Manually moving the insertion rod 41 separates it from the limiting cylinder 31, facilitating the placement and removal of the crossbar 4. The number of connecting parts 5 can be increased or decreased. Each connecting part 5 includes symmetrically distributed sleeves 51, connecting rods 52 installed between opposing sleeves 51, and fixing blocks 53 welded to the sleeves 51. An adjusting rod 61 is rotatably connected to the fixing block 53, allowing adjustment of the angle of the adjusting rod 61. This facilitates manual insertion of both ends of the workpiece through the suspension tube 62. The end of the crossbar 4 is slidably connected to a plug rod 41, which is inserted into the interior of the limiting cylinder 31 to limit the plug rod 41. A support plate 7 is fixed to the bottom of the fixing plate 3 by screws at its top end. The support plate 7 serves to support and fix the protective box 81. A movable component is also included, which is fixed to the support plate 7 by screws. The protective box 81, the drive cylinder 84 installed inside the protective box 81, the moving plate 82 fixed to one end of the drive cylinder 84 by screws, and the actuating plate 83 perpendicular to the moving plate 82 are all included. The cylinder body of the drive cylinder 84 is installed inside the protective box 81, and the protective box 81 serves to protect the drive cylinder 84. The actuating plate 83 is tangent to the tube or columnar workpiece suspended on the suspension tube 62. When the drive cylinder 84 drives the moving plate 82 and the actuating plate 83 to move back and forth, under the action of friction, the actuating plate 83 actuates the tube or columnar workpiece, causing it to rotate and exposing the outer surface of the tube or columnar workpiece to avoid overlapping.

[0016] In this embodiment, a concave circular groove is provided on the surface of the limiting cylinder 31 facing the insertion rod 41. One end of the insertion rod 41 is embedded in the circular groove. A toggle rod b passes through the insertion rod 41. By toggle rod b, the position of the insertion rod 41 can be moved. The insertion rod 41 and the limiting cylinder 31 are separate structures. By manually moving the insertion rod 41, the insertion rod 41 can be separated from the limiting cylinder 31, which facilitates the picking and putting of the crossbar 4.

[0017] In this embodiment, the sleeve 51 is sleeved on the outside of the crossbar 4. The inner diameter of the sleeve 51 is the same as the outer diameter of the crossbar 4. The fixing block 53 has a "U" shaped structure. The sleeve 51 is supported by the crossbar 4. The sleeve 51 and the crossbar 4 are separate structures, which makes it easy to manually remove the sleeve 51.

[0018] In this embodiment, a rotating pin is provided on the fixing block 53, which passes through the top of the adjusting rod 61. The adjusting rod 61 is rotatably connected to the fixing block 53, and the angle of the adjusting rod 61 can be manually changed so that both ends of the workpiece pass through the suspension tube 62 respectively. The axis of the adjusting rod 61 is perpendicular to the axis of the suspension tube 62 and the axis of the sleeve 51. The axis of the suspension tube 62 and the axis of the sleeve 51 are in a perpendicular state. The workpiece passes through the suspension tube 62, and the workpiece is in a perpendicular state with the sleeve 51 and the crossbar 4. Multiple workpieces can be placed side by side and at equal intervals.

[0019] In this embodiment, the support plate 7 is an "L"-shaped right-angle structure. The actuating plate 83 is parallel to the bottom of the crossbar 4 and the support plate 7. The distance between the moving plate 82 and the support plate 7 is 3 mm. There is a gap between the moving plate 82 and the support plate 7 to avoid affecting the movement of the moving plate 82. The bottom horizontal cross-section of the inner circle of the suspended circular tube 62 is surface F. The top surface of the actuating plate 83 is flush with surface F. When the tube or columnar workpiece is placed, the workpiece is tangent to the actuating plate 83. When the driving cylinder 84 drives the moving plate 82 and the actuating plate 83 to move back and forth, under the action of friction, the actuating plate 83 actuates the tube or columnar workpiece, making it rotate, so that the outer surface of the tube or columnar workpiece is exposed, avoiding overlapping parts.

[0020] Working principle and usage process of this utility model: With the door 21 open, when placing tubular or cylindrical workpieces inside the horizontal tensile testing chamber 2, Manually adjust the angle of the adjusting rod 61, manually pass one end of the workpiece through the suspension tube 62 on one side, then reset the adjusting rod 61 to change the angle, and pass the other end of the workpiece through the suspension tube 62. At this time, both ends of the workpiece are in a suspended state suspended on the suspension tube 62. When placing tubular or cylindrical workpieces, the workpieces should be tangent to the actuating plate 83; When the driving cylinder 84 drives the moving plate 82 and the actuating plate 83 to move back and forth, under the action of friction, the actuating plate 83 actuates the tube and columnar workpiece, causing them to rotate and exposing the outer surface of the tube and columnar workpiece to avoid overlapping parts. When the moving plate 82 and the toggle plate 83 driven by the driving cylinder 84 are in a moving state, multiple workpieces can be toggled at the same time. In summary: The experimental box of this application has an auxiliary suspension design for moving and adjusting the angle of multiple workpieces. The two ends of the workpieces are suspended on the suspension tube 62. The workpieces are in a suspended state. When the moving plate 82 and the toggle plate 83 driven by the driving cylinder 84 are in a moving state, multiple workpieces can be moved at the same time, so that the outer surface of the tube and columnar workpieces is exposed and overlapping parts are avoided.

[0021] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
