[0024] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0025] like Figure 1-2 As shown, the multifunctional molecular pump test bench in this embodiment includes a test frame 100 for installing a molecular pump 130 and a counterweight frame 110 arranged on one side of the test frame 100, and the test frame 100 can be flipped onto the counterweight frame 110; the test frame 100 includes a mounting frame 101 and support legs 102 arranged at the four corners of the mounting frame 101, and a first foot cup 103 for supporting the support leg 102 is provided at the bottom end of the support leg 102, and a detachable mounting plate 120 for installing the molecular pump 130 is provided on the upper side of the mounting frame 101; the counterweight frame 110 includes a counterweight base plate 111, and second foot cups 112 for supporting the counterweight base plate 111 are provided on both sides of the counterweight base plate 111, and one end of the counterweight base plate 111 is rotatably connected to the opposite support leg 102 through a rotating member, and the test frame 100 is also provided with a support member for flipping it onto the counterweight frame 110 for support.

[0026] In actual use of this embodiment, the test stand 100 is also provided with a test device for testing the molecular pump 130. The test device is an existing structure, and the structure disclosed in the publication number CN212079601U can be adopted, which can test various parameters of the molecular pump 130 (such as molecular pump speed, vacuum degree, etc.);

[0027] In this embodiment, the mounting plate 120 is mounted on the mounting frame plate 101, and the molecular pump 130 is mounted on the mounting plate 120, so that the molecular pump 130 can be preferably installed on the test frame 100. When the test frame 100 is vertically arranged, that is, the first foot cup 103 contacts the ground to support the test frame 100, so that the molecular pump 130 is in a vertical state. At this time, the test equipment can test various parameters of the molecular pump 130 in the vertical state; when the test frame 100 is flipped onto the counterweight frame 110 through the rotating member, at this time, the support member on the test frame 100 can support the test frame 100, so that the test frame 100 is horizontally located above the counterweight frame 110, even if the molecular pump 130 is in a horizontal state, at this time, the test equipment can test various parameters of the molecular pump 130 in the horizontal state, so that the molecular pump test bench can test various parameters of the molecular pump 130 in the vertical and horizontal states, so that the test of the molecular pump 130 is more comprehensive;

[0028] Among them, through the setting of the counterweight frame 110, in actual use, the counterweight base plate 111 is placed on the ground through the second foot cup 112. In actual use, threaded holes for installing the second foot cup 112 are set on the counterweight base plate 111 and on both sides. By rotating the second foot cup 112 in the corresponding threaded hole, the counterweight base plate 111 can be leveled. When the test frame 100 is in a vertical state, the counterweight base plate 111 is connected to the relative support leg 102 through a rotating member, and then the test frame 100 is pulled, which can better prevent the molecular pump 130 from moving during testing on the test frame 100; when the test frame 100 is flipped to be horizontal on the counterweight base plate 111, the counterweight base plate 111 can adjust the center of gravity of the test frame 100. At this time, it can better prevent the molecular pump 130 from moving during testing on the test frame 100, thereby improving the test effect;

[0029] In this embodiment, in order to improve the strength of the test frame 100, a reinforcing rib plate 107 is provided between the mounting frame plate 101 and the supporting leg 102, thereby preferably strengthening the strength of the test frame 100 and preventing the molecular pump 130 from moving when being tested thereon.

[0031] In this embodiment, the installation plate 120 can be preferably assembled and disassembled from the installation frame plate 101 by passing bolts through the corresponding installation holes 302 and through holes 513 , that is, the installation plate 120 can be assembled and disassembled from the test stand 100 .

[0032] Combination Figure 4 and Figure 5 As shown, in this embodiment, a measuring hole 511 and a rotation speed hole 512 are provided at the center of the mounting plate 120 , and blind holes 514 for installing the molecular pump 130 are evenly distributed on the upper side of the mounting plate 120 .

[0033] In actual use of this embodiment, a cover plate is installed at the measuring hole 511, through which the test equipment can test the vacuum degree of the molecular pump 130; a special sight glass is installed at the speed hole 512, which is convenient for the test equipment to test the speed of the molecular pump 130;

[0034] The molecular pump 130 is provided with a mounting flange, and the blind holes 514 are evenly distributed along the circumference of the mounting flange. The mounting flange is connected to the blind holes 514 by bolts, thereby realizing the installation of the molecular pump 130 on the mounting plate 120. In order to ensure the sealing of the molecular pump 130, a sealing gasket is provided between the mounting flange and the mounting plate 120.

[0035] In actual use, there are multiple groups of blind holes 514 distributed along the circumference of the mounting plate 120 to meet the sealing installation of different types of molecular pumps 130 on the mounting plate 120, thereby improving the applicability of the molecular pump test bench.

[0036] Combination Figure 1 As shown, in this embodiment, the rotating member includes a rotating seat 140 relatively arranged on the counterweight base plate 111, a rotatable shaft 141 is provided between the rotating seats 140, and mounting seats 150 for connecting to the corresponding ends of the shaft 141 are respectively provided on the opposite supporting legs 102.

[0037] In this embodiment, the width of the counterweight base plate 111 is smaller than the spacing between adjacent support legs 102, that is, one end of the counterweight base plate 111 can extend into the test frame 100, wherein the rotating seat 140 is fixedly installed at one end of the counterweight base plate 111 by bolts, for realizing the rotating installation of the rotating shaft 141; wherein the mounting seat 150 is fixedly installed on the side relative to the support leg 102 by bolts, so that the two ends of the rotating shaft 141 can be fixedly installed between the corresponding mounting seats 150, thereby preferably realizing the rotating connection between the support leg 102 and the counterweight base plate 111, so that the test frame 100 is flipped over to the counterweight base plate 111.

[0038] In this embodiment, the support member includes fixing blocks 104 disposed on two opposite sides of the mounting frame plate 101 , and the fixing blocks 104 are provided with flip support foot cups 105 .

[0039] In this embodiment, the fixed block 104 is fixedly connected to the side opposite to the mounting frame 101, and a threaded hole is provided thereon. The flip support foot cup 105 is threadedly connected to the threaded hole. When the test frame 100 is flipped onto the counterweight frame 110, the flip support foot cup 105 is rotated to rise and fall in the threaded hole, so that the flipped test frame 100 can be better leveled and the molecular pump 130 can be better placed in a horizontal state.

[0040] In this embodiment, a socket 106 is further provided on the fixed block 104, and a force rod (not shown in the figure) is provided in the socket 106. The force rod can be installed on the fixed block 104 by threading the force rod into the socket 106. Therefore, by holding the force rod, the operator can flip the test frame 100 conveniently.

[0041] In this embodiment, handles 121 are provided on both sides of the mounting plate 120. The handles 121 facilitate the operator to carry the mounting plate 120. At the same time, when the mounting plate 120 is fixedly installed on the test frame 100, the handles 121 facilitate the operator to flip the test frame 100.

[0042] Working principle: By fixing the molecular pump 130 on the mounting plate 120, which is fixed on the test frame 100, the molecular pump 130 can be effectively prevented from moving during the test, which affects the test of the molecular pump 130; wherein, by flipping the test frame 100 onto the counterweight frame 110, the molecular pump 130 on the test frame 100 can be switched from a vertical state to a horizontal state, so that the molecular pump test bench can test various parameters of the molecular pump 130 in the vertical and horizontal states, and the test is more comprehensive.
