[0055] Unless otherwise specified, all percentages, parts, ratios, etc. mentioned in this specification are based on weight, unless being based on weight would not be in accordance with the common understanding of those skilled in the art.

[0056] Example 1:

[0057] like Figures 1-9 As shown, a tilt adjustment fixture for an automotive air conditioning system test specimen includes:

[0058] Fixed bracket 1, movable bracket 2, tilt adjustment assembly 3, and clamping assembly 4;

[0059] The fixed bracket 1 is fixedly installed;

[0060] The movable support 2 is mounted on the fixed support 1 via the tilt adjustment components 3 provided on both sides. The movable support 2 is tilted, and the tilt of the movable support 2 is adjusted by the tilt adjustment components 3.

[0061] The clamping assembly 4 is mounted on the movable bracket 2, and the clamping assembly 4 fixes the test sample 00 on the movable bracket 2.

[0062] Specifically, the fixed bracket 1 is installed on the testing equipment, and the movable bracket 2 is loaded with the corresponding test specimen 00. When adjusting the tilt angle of the test specimen 00 (the test specimen 00 in the attached drawings of this application is an automotive air conditioning compressor), the movable bracket 2 is adjusted by the tilt adjustment component 3. In addition, the test specimen 00 is fixed on the movable bracket 2 by the clamping component 4.

[0063] Furthermore, the fixed bracket 1 includes a bottom frame 11 and mounting columns 12. The bottom frame 11 is square-shaped, and the mounting columns 12 are vertically mounted on the bottom frame 11. Two sets of mounting columns 12 are symmetrically arranged, and the movable bracket 2 is installed between the two sets of mounting columns 12.

[0064] Furthermore, the bottom frame 11 includes two sets of parallel horizontal bars 111 and two sets of parallel vertical bars 112. Adjacent horizontal bars 111 and vertical bars 112 are connected to each other by die-cast corner brackets 113, and the mounting column 12 is connected to the bottom frame 11 by die-cast corner brackets 113.

[0065] In addition, the movable support 2 includes an outer frame 21 and a movable mounting rod 22;

[0066] The outer frame 21 is square in shape, and its two sides are movably connected to the fixed bracket 1.

[0067] The movable mounting rod 22 is installed inside the square frame 210 of the outer frame 21. Two sets of the movable mounting rod 22 are arranged in parallel, and the spacing between the movable mounting rods 22 is adjustable.

[0068] Furthermore, the outer frame 21 includes a set of horizontal frames 211 and a set of vertical frames 212 arranged in parallel. The horizontal frames 211 and the vertical frames 212 are connected end to end, and the inner and outer walls of the horizontal frames 211 and the vertical frames 212 are provided with sliding grooves 213.

[0069] Furthermore, the movable mounting rod 22 is connected to the outer frame 21 via a corner bracket connector 23. The corner bracket connector 23 is connected to the outer frame 21 via a T-nut 24 and an adjusting handle screw 25. The T-nut 24 is slidably installed in the slide groove 213, and the adjusting handle screw 25 passes through the corner bracket connector 23 and is threadedly connected to the T-nut 24.

[0070] It should be noted that both the fixed bracket 1 and the movable bracket 2 are assembled using aluminum profiles. The aluminum profiles of the bottom frame 11 and the mounting column 12 are of the same type. Furthermore, the horizontal bar 111, the vertical bar 112, and the four side arms of the mounting column 12 are all provided with corresponding grooves or sliding slots. When the horizontal bar 111 and the vertical bar 112 are assembled to form the bottom frame 11, the angle between the horizontal bar 111 and the vertical bar 112 is connected by a die-cast corner seat 113. Specifically, a connecting block corresponding to the die-cast corner seat 113 is set in the groove of the horizontal bar 111 and the vertical bar 112. A bolt is inserted from the outside, and the bolt passes through the mounting hole on the die-cast corner seat 113 and connects with the connecting block, thereby realizing the installation connection of the horizontal bar 111 and the vertical bar 112. It should be emphasized that the installation connection method of the mounting column 12 and the fixed bracket 1 is similar to the installation connection method of the horizontal bar 111 and the vertical bar 112.

[0071] Furthermore, the outer frame 21 in the movable support 2 is also formed by splicing together the horizontal frame 211 and the vertical frame 212 of the aluminum profile structure. The splicing method is similar to the assembly method of the bottom frame 11. Both are assembled by threaded connection of connectors and bolts. The aluminum profile splicing to form a square frame structure is a conventional structural method. Therefore, it will not be described in detail here.

[0072] To further explain, the installation connection between the movable mounting rod 22 and the outer frame 21 is achieved by using a corner seat connector 23, a T-nut 24, and an adjusting handle screw 25. Specifically, the installation connection between the corner seat connector 23 and the movable mounting rod 22 is the same as that between the die-cast corner seat 113 and the crossbar 111. However, the installation connection structure between the corner seat connector 23 and the outer frame 21 is more unique. The T-nut 24 is located in the slide groove 213, and the adjusting handle screw 25 passes through the corner seat connector 23 and connects with the T-nut 24. When unlocking is required, simply turn the adjusting handle screw 25 slightly to release the lock between the movable mounting rod 22 and the outer frame 21, allowing the movable mounting rod 22 to slide relative to the outer frame 21.

[0073] To further explain, in order to improve the installation stability of the movable mounting rod 22 and the outer frame 21, a connection structure is provided on the back side of the outer frame 21 and the movable mounting rod 22. The connection structure is located at both ends of the movable mounting rod 22 along its length, and includes two sets of connecting blocks 200 and a set of connecting plates 201. The connecting blocks 200 have threaded rods 202 protruding from them. The connecting blocks 200 are respectively located in the grooves of the movable mounting rod 22 and the outer frame 21. The two ends of the connecting plates 201 are respectively sleeved on the corresponding threaded rods 202. Then, the connecting plates 201 are locked by nuts, so that the movable mounting rod 22 can still move along the groove of the outer frame 21 while maintaining a stable connection.

[0074] Example 2:

[0075] The structure of the slope adjustment component of Embodiment 2 of this utility model is described with reference to Embodiment 1:

[0076] like Figure 10 As shown, the inclination adjustment assembly 3 includes a cross steering connecting plate 31, a first hammer nut 32, a second hammer nut 33, a third hammer nut 34, a rotating screw 35, a locking screw 36, and a movable handle screw 37.

[0077] The cross-steering connecting plate 31 includes a vertically arranged horizontal portion 311 and a semi-circular portion 312. The horizontal portion 311 is connected to the mounting column 12 via a first hammer nut 32 and a locking screw 36. The first hammer nut 32 is disposed in a sliding groove 121 of the mounting column 12. The locking screw 36 passes through the horizontal portion 311 and is threadedly connected to the first hammer nut 32, thereby fixing the cross-steering connecting plate 31 onto the mounting column 12. The semi-circular portion 312 is connected to the outer frame 21 via a second hammer nut 33, a third hammer nut 34, a rotating screw 35, and a movable handle screw 37. The second hammer nut 33 and the third hammer nut 34 are disposed on the outer frame 21. Within the groove 213 of frame 21, the rotating screw 35 passes through the semicircular portion 312 and is threadedly connected to the second hammer nut 33, thereby allowing the outer frame 21 to rotate around the rotating screw 35. The movable handle screw 37 passes through the semicircular portion 312 and is threadedly connected to the third hammer nut 34. The semicircular portion 312 is provided with a semicircular adjustment groove 313 for the movable handle screw 37 to move and adjust. When the outer frame 21 rotates and swings to the corresponding tilt angle, the rotational freedom of the outer frame 21 can be locked by rotating the movable handle screw 37 and through the threaded connection between the movable handle screw 37 and the third hammer nut 34, thereby fixing the outer frame 21 and thus fixing the test specimen 00.

[0078] It should be noted that when the inclination adjustment component 3 adjusts the inclination of the movable support 2, the specific adjustment steps are as follows:

[0079] First, rotate the movable handle screw 37 to release it, so that the outer frame 21 can rotate freely. The outer frame 21 can rotate and swing around the rotating screw 35. After the outer frame 21 rotates and swings to the corresponding tilt angle, rotate the movable handle screw 37 to the locked state. It is worth emphasizing that when the outer frame 21 rotates, the movable handle screw 37 is guided and adjusted along the semi-circular adjustment groove 313.

[0080] Example 3:

[0081] The structure of the clamping assembly of Embodiment 3 of this utility model is described with reference to Embodiment 1:

[0082] like Figure 11 As shown, the clamping assembly 4 includes a clamping slider 41, a locking stud 42, a fastening connector 43, and an adjusting screw 44;

[0083] The clamping slider 41 is slidably disposed within the adjustment groove 221 of the movable mounting rod 22;

[0084] The locking stud 42 is threaded through the clamping slider 41, and the locking stud 42 locks the clamping slider 41.

[0085] The fastening connector 43 is mounted on the clamping slider 41 by the adjusting screw 44. The fastening connector 43 is semi-circular and is fastened to the smooth rod 001 on the test sample 00.

[0086] The adjusting screw 44 is vertically inserted through the clamping slider 41. The fastening connector 43 is installed on the top of the adjusting screw 44, and a spring 45 is sleeved on the adjusting screw 44 so that the fastening connector 43 can be elastically adjusted.

[0087] Furthermore, the fastening connector 43 extends downward and is provided with a positioning plate 431, which is correspondingly interlocked with the slot 412 on the clamping slider 41.

[0088] It should be noted that when mounting the test specimen 00 onto the movable mounting rod 22, the fastening connector 43 is first fastened to the smooth rod 001 on the test specimen 00. Specifically, the clamping assembly 4 is provided with two sets of four fastening connectors 43, which are respectively located at the four corners of the test specimen 00 to install and fix the test specimen 00. After the fastening connector 43 has completed the fastening work, the locking stud 42 is rotated to make the fastening connector 43 completely fasten the smooth rod 001. Then, the clamping slider 41 is completely fixed on the movable mounting rod 22 by adjusting the screw 44, so that the test specimen 00 is completely fixed on the movable bracket 2, thereby achieving the purpose of quickly fixing the test specimen 00 on the movable bracket 2.

[0089] To further explain, when the locking stud 42 is used to lock the fastening connector 43, the positioning plate 431 on the fastening connector 43 cooperates with the slot 412, so that the fastening connector 43 will not be misaligned during the fastening and locking process.

[0090] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
