Specifically, in the present invention, the user's operating surface is the front, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the upper, and other descriptions indicating directions are defined based on "upper" and "lower".

[0030] In various drawings of the present invention, for the convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structural parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

[0031] The utility model provides a test fixture for refrigeration equipment, which is used to limit the refrigeration load during the refrigeration capacity test of the refrigeration equipment. Figures 1 to 7 As shown, the test fixture includes a bracket 10 and a baffle structure 20 fixed to at least one side of the bracket 10 along a first direction. The size of the bracket 10 in the test fixture of the utility model is adjustable along the first direction, and the size of the baffle structure 20 is adjustable along the second direction, thereby improving the coverage of the test fixture and improving the applicability of the test fixture.

[0032] In the present invention, the first direction and the second direction are perpendicular to each other. The first direction is preferably along the length direction of the bracket 10 , and correspondingly, the second direction is along the width direction of the bracket 20 .

[0033] The bracket 10 includes a first connector 11 and a second connector 12 that are plug-fitted along a first direction. The first connector 11 and the second connector 12 are plug-fitted to adjust the size of the bracket 10 along the first direction, so that the test fixture can be suitable for refrigeration loads of different sizes.

[0034] like Figures 4 to 7 As shown, the first connecting member 11 includes a plug-in portion 112, the length of the plug-in portion 112 extends along the second direction, the second connecting member 12 includes a docking portion 121 that cooperates with the plug-in portion 112, and the docking portion 121 is provided with a plug-in groove (not shown) that opens toward the plug-in portion 112. The width range of the bracket 10 can be adjusted by adjusting the plug-in portion 112 to different depths in the plug-in groove.

[0035] As a preferred embodiment of the present utility model, Figure 3 and Figure 4As shown, the first connector 11 also includes a base 111, the plug-in portion 112 is fixed on the base 111, the thickness of the base 111 is greater than the size of the plug-in portion 112, and the structural strength of the bracket 10 is improved; the thickness of the base 111 is equivalent to the size of the docking portion 121, and when the first connector 11 and the second connector 12 are plugged and matched, the first connector 11 and the second connector 12 are on the same plane, ensuring the aesthetics of the bracket 10. In this embodiment, the depth of the plug-in slot is less than the size of the docking portion 121 along the first direction, that is, the adjustment range between the first connector 11 and the second connector 12 is less than the width of the docking portion 121.

[0036] As another preferred embodiment of the utility model, the depth of the plug-in slot is consistent with the size of the docking portion 121 along the first direction. When the width of the bracket 10 along the first direction is at the minimum state, the first connecting member 11 as a whole is located in the plug-in slot as the plug-in portion 112. In this embodiment, the first connecting member 11 does not include the base 111, so that there is a larger adjustment range between the first connecting member 11 and the second connecting member 12.

[0037] As another preferred embodiment of the present invention, Figures 2 to 5 As shown, the first connecting member 11 also includes an adjusting portion 113 spaced apart from the plug-in portion 112, and the docking portion 121 also includes an adjusting slot 1212 spaced apart from the plug-in slot and used to accommodate the adjusting portion 113. In this embodiment, the length of the plug-in portion 112 along the second direction is less than the length of the docking portion 121, and the adjusting portion 113 cooperates with the docking portion 121 together, and the plug-in slot of the docking portion 121 is spaced apart from the adjusting slot 1212, which reduces the size of the slot, improves the strength of the docking portion 121, and thereby improves the structural strength of the bracket 10.

[0038] like Figure 3 As shown, in order to accurately adjust the width of the bracket 10, the adjusting portion 113 has an end face 1131 along the second direction, and the end face 1131 is provided with evenly arranged scale marks 1132. The adjusting groove 1212 has an opening 1213 that exposes the end face 1131 to display the scale marks 1132, which is convenient for observing the scale marks 1213 on the adjusting portion 113.

[0039] Preferably, if Figure 3 and Figure 5As shown, the first connecting member 11 also includes a first limiting portion 114 arranged on a side of the adjusting portion 113 away from the base 111, and the docking portion 121 also includes a first stopping portion 1214 arranged at the opening of the adjusting groove 1212 to prevent the first limiting portion 114 from falling off from the adjusting groove 1212 along the first direction. In the process of adjusting the width of the bracket 10, the adjusting portion 113 is prevented from falling off from the adjusting groove 1212, thereby ensuring the working efficiency of adjusting the width of the bracket 10.

[0040] Furthermore, the bracket 10 further includes a first fixing member 13 for fixing the first connecting member 11 at different positions of the second connecting member 12 along the first direction, so as to improve the structural strength of the bracket 10. Specifically, the first fixing member 13 includes a first fastener 131 and a first fixing hole 132 provided on the docking portion 121 and threadedly connected to the first fastener 131, the first fastener 131 passes through the first fixing hole 132 and abuts against the plug-in portion 112, and preferably, the first fixing hole 132 is provided at a position of the docking portion 121 close to the plug-in portion 112.

[0041] In this embodiment, the first fixing member 13 includes a plurality of groups, and a plurality of first fixing holes 132 are arranged on the docking portion 121 at intervals along the length direction of the bracket 10 to improve the fixing position between the first connecting member 11 and the second connecting member 12, thereby improving the overall structural strength of the bracket 10.

[0042] Furthermore, the test fixture is provided with two baffle structures 20 which are respectively fixed on both sides of the bracket 10 along the first direction, that is, the baffle structure 20 and the bracket 10 are in an I-shape. In the refrigeration capacity test of the refrigeration equipment, the refrigeration load is located in the space formed by the baffle structure 20 and the bracket 10, and the position of the refrigeration load is limited to prevent the refrigeration load from moving during the test, thereby ensuring the accuracy of the test.

[0043] Furthermore, if Figures 1 to 7 As shown, the baffle structure 20 includes a fixed plate 21 fixed to the bracket 10 and a movable plate 22 slidably matched with the fixed plate 21 along the second direction. The total length of the baffle structure 20 along the second direction is increased by moving the position of the movable plate 22 relative to the fixed plate 21. It can be understood that the sliding directions of the two movable plates on the two baffle structures 20 relative to the fixed plate 21 are the same or opposite, and the design is adjusted according to actual needs.

[0044] Specifically, Figure 5 and Figure 7As shown, the movable plate 22 includes a plate body 221, a second limiting portion 222 arranged at the end of the plate body 221 along the second direction, the fixed plate 21 includes a main body 211 fixed to the bracket 10, a slide groove 212 arranged on the main body 211 and extending along the second direction to accommodate the movable plate 22, and a second stop portion 214 arranged at the end of the slide groove 212 to cooperate with the second limiting portion 222 to prevent the movable plate 22 from falling off from the end of the fixed plate 21, increasing the risk of reinstallation, thereby improving the work efficiency of adjusting the baffle structure 20.

[0045] The baffle structure 20 also includes a second fixing member 23 for fixing the movable plate 22 on the fixed plate 21 along a second direction. When the movable plate 22 is located at different positions of the fixed plate 21, the second fixing member 23 can be used to fix the movable plate 22 on the fixed plate 21 to improve the overall structure of the test work.

[0046] As another preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, the fixed plate 21 also includes at least one through hole 213 provided in the slide groove 212, and the through hole 213 extends in the same direction as the slide groove 212. In this embodiment, the through holes 213 are provided with two and are spaced apart on both sides of the width of the slide groove 213. The second fixing member 23 includes a mounting column 231 fixed to the movable plate 22 and capable of passing through the through hole 213, and a mounting member 232 threadedly engaged with the mounting column 231. The outer diameter of the mounting member 232 is not less than the inner diameter of the through hole 213 along its width, and the mounting member 232 engages with the mounting column 231 from the side of the fixed plate 21 away from the movable plate 22.

[0047] As another preferred embodiment of the utility model, the fixed plate 21 also includes a limiting plate (not shown) located at the opening of the slide slot 212 to limit the movable plate 22, the limiting plate extends along the second direction, and the movable plate 22 is limited between the bottom wall of the slide slot 212 and the limiting plate. In this embodiment, the second fixing member 23 includes a second fastener, a second fixing hole provided on the limiting plate and threadedly matched with the second fastener. In this embodiment, the structure of the second fixing member 23 is the same as that of the first fixing member 13, the second fastener 23 passes through the second fixing hole and abuts against the movable plate 22, and a plurality of second fixing holes are provided and are spaced apart on the limiting plate along the second direction.

[0048] In summary, the test fixture for refrigeration equipment of the utility model is used to limit the refrigeration load in the refrigeration capacity test of the refrigeration equipment. The position of the first connecting member 11 and the second connecting member 12 along the first direction can be adjusted, and the position of the movable plate 22 relative to the fixed plate 21 along the second direction can be adjusted. The coverage range of the test fixture can be improved, thereby improving the applicability of the test fixture. In addition, the structure is simple and easy to promote.
