[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0074] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0075] Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0076] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0077] Example 1

[0078] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a device for mounting instruments and equipment at an observation window of an experimental space, comprising a flange 1, a threading connection portion 2, a connecting frame 3, a fastening portion 4, a mounting platform 5, a clamp 6 and a hanging cable 7.

[0079] See also Figure 3 and Figure 4 As shown, two first threaded blind holes 11 are provided laterally at intervals on the upper portion of one end of the flange 1, and two second threaded blind holes 12 are provided laterally at intervals on the lower portion. Each first threaded blind hole 11 is threadedly connected to a threading connection portion 2. It should be noted that the flange 1 can be a new flange that matches the shape of the observation window and is manufactured using the solution of the present application; threaded blind holes can also be directly machined into the existing flange, and this is not limited here.

[0080] See also Figure 1 and Figure 2 As shown, the connecting frame 3 includes two longitudinal rods 31 arranged in parallel and spaced apart, and a cross rod 32 vertically connecting the plurality of longitudinal rods 31. The cross rod 32 is provided with a first through hole corresponding to the second threaded blind hole 12. The fastening portion 4 passes through the first through hole and is threadedly connected to the second threaded blind hole 12 to fix the connecting frame 3 on the flange 1.

[0081] See also Figure 1 、 Figure 2 and Figure 6 As shown, the mounting platform 5 is used to support instruments and equipment. One end of the mounting platform 5 is connected to two clamps 6, each clamp 6 cooperates with a longitudinal rod 31, and when locked, the clamp 6 is fixed relative to the longitudinal rod 31, and when released (unlocked), it can move in the vertical direction of the longitudinal rod 31.

[0082] See also Figure 1 and Figure 2 As shown, in this embodiment, two suspension cables 7 are used, one end of the two suspension cables 7 is connected to the erection platform 5, and the other end is connected to the threading connection part 2. The suspension cables 7 cooperate with the clamp 6 to fix the erection platform 5.

[0083] During use, the mounting device is secured to the observation window of an experimental space, such as a wind tunnel, vacuum tank, or sterile chamber, by a flange. The lower end of the connecting frame rests on the ground, and instruments are placed on the mounting platform. The height of the mounting platform can be adjusted to align the instruments with the observation window of the experimental space to meet experimental requirements. To adjust the height of the mounting platform, the mounting platform is moved by loosening the clamps. Once moved to the desired position, the clamps are tightened, and the suspension cables are adjusted to secure the platform in place. The entire adjustment process is stepless, providing greater precision than conventional hydraulic lifts. Furthermore, the device is adaptable to various instruments and equipment, offering high versatility, a simple structure, and low cost. Furthermore, installation is safer. During installation, the flange can be connected to the observation window first, and then the connecting frame can be mounted on the flange. Because the connecting frame and flange are connected via threaded blind holes, this prevents interference with the flange connection during installation, thereby preventing breakage of optical glass, such as lenses, in the observation window due to uneven force on the flange during mounting of the connecting frame. In addition, due to the use of blind holes, the existing flange can be directly modified to install the connecting frame, or a new flange can be replaced to install the connecting frame.

[0084] In some embodiments, see Figure 2 and Figure 6 As shown, the longitudinal rod 31 is a round rod. The clamp 6 includes a U-shaped clamp 61, a first bolt 62, and a first nut 63. The U-shaped clamp 61 includes an arc segment that matches the round rod and straight segments arranged at both ends of the arc segment. The two straight segments are arranged in parallel and spaced apart. Second through holes are provided in the two straight segments. The two second through holes are arranged coaxially. The first bolt 62 passes through the two second through holes and engages with the first nut 63. By rotating the first nut 63, the U-shaped clamp 61 can be deformed, thereby clamping or releasing the longitudinal rod 31.

[0085] In order to increase friction and improve the clamping effect, in some embodiments, see Figure 6 As shown, at least a rubber layer 64 or a sponge layer is provided on the inner side of the arc section of the U-shaped clamping plate 61 .

[0086] In order to adapt to instruments and equipment of different sizes and provide a certain degree of fixation for the instruments and equipment, in some embodiments, see Figure 1 、 Figure 2 and Figure 6As shown, the mounting platform 5 includes a flat plate 51 and two baffles 52. The flat plate 51 is provided with a plurality of slots 511 at intervals. Each baffle 52 can be inserted into any of the slots 511. Instruments and equipment are placed between the two baffles 52. By cooperating between the baffles 52 and different slots 511, the distance between the two baffles 52 can be adjusted. Furthermore, the slots 511 can increase the friction between the instruments and equipment and the flat plate 51. It should be noted that, depending on the appearance of the instruments and equipment, the shape of the baffles 52 can be any matching shape. For example, the baffles 52 can be straight, curved, or a combination of straight and curved, without limitation herein.

[0087] Preferably, see Figure 6 As shown, the flat plate 51 is provided with a cable hole 512 for connecting with a suspension cable.

[0088] The threading connection portion 2 can be any structure capable of threading, for example, a radially perforated stud, a screw, etc. In some embodiments, see Figure 2 and Figure 7 As shown, the wire connection portion 2 includes a second bolt 21 and a second nut 22. The shank of the second bolt 21 is threadedly connected to the first threaded blind hole 11. The second nut 22 is threadedly connected to the shank of the second bolt 21 and abuts against the flange 1, facilitating the connection and strengthening the fixing effect of the second bolt 21 and the flange 1. A wire threading hole 211 is provided on the second bolt 21. The wire threading hole 211 is located between the second nut 22 and the head of the second bolt 21 to facilitate the passage and fixation of the suspension cable 7.

[0089] The fastening portion 4 may be any fastener, such as a screw, a bolt, a stud and a nut. Figure 1 、 Figure 2 and Figure 8 As shown, the fastening portion 4 includes a stud 41, a third nut 42, and a fourth nut 43. The stud 41 passes through the first through-hole and is threadedly connected to the second threaded blind hole 12. The third nut 42 and the fourth nut 43 are threadedly connected to the stud 41 and are respectively located on both sides of the crossbar 32. The structure of the fastening portion 4 is that the two nuts cooperate with the stud, which can not only achieve a relatively stable fixation of the connecting frame 3, but also adjust the distance between the connecting frame 3 and the flange 1 through the nut located between the crossbar 32 and the flange 1, thereby achieving fine-tuning of the distance between the mounting platform 5 and the flange 1, that is, achieving fine-tuning of the distance between the instrument and the observation window.

[0090] In order to better achieve the clamping and fixing of the lens at the observation window, in one embodiment, see Figure 4 and Figure 5As shown, an annular groove 13 is provided at the other end of the flange 1 (the end facing the observation window). The annular groove 13 surrounds the center hole 14 of the flange 1 and is connected to the center hole 14. That is, the annular groove 13 is a sunken groove with an L-shaped cross section. Preferably, a sealing ring 15 is provided in the annular groove 13.

[0091] In this embodiment, the suspension cable 7 is made of a nylon rope or other cable with good flexibility and toughness.

[0092] Example 2

[0093] like Figure 9 As shown, the second embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that: a first threaded blind hole 11 is provided on the upper part of one end of the flange 1, and a wire connection part 2 is threadedly connected at the first threaded blind hole 11. There are two suspension cables 7, and each of the two suspension cables 7 has one end connected to the wire connection part 2, and the other end is connected to two places of the mounting platform 5, forming a triangular fixation.

[0094] Example 3

[0095] like Figure 10 As shown, the third embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that the suspension cable 7 is in a herringbone shape, that is, one end has a wire end, which is connected to the threading connection part 2, and the other end has two wire ends, which are respectively connected to two places of the mounting platform 5. Only one adjustment is required during adjustment, which makes adjustment more convenient.

[0096] Example 4

[0097] like Figure 11 and Figure 12 As shown, based on any one of the mounting devices in Examples 1 to 3, the mounting platform 5 is connected to the clamp 6 through a rotating member 8, so that the mounting platform 5 can rotate relative to the clamp 6, thereby realizing angle adjustment of the mounting platform 5, and then realizing angle adjustment of the instrument equipment to meet more testing and observation requirements.

[0098] The rotating member 8 can be realized by adopting a hinge structure or similar structure. In one embodiment, see Figure 12As shown, the rotating member 8 includes an annular seat 81, a bearing (not shown in the figure), a rotating rod 82 and a connecting rod 83. The annular seat 81 is fixedly connected to the clamp 6 (which can be welded or integrally connected, etc., which is not limited here), the outer ring of the bearing is fixedly connected to the annular seat 81, the rotating rod 82 extends through the bearing and is fixedly connected to the inner ring of the bearing, and the two ends of the rotating rod 82 are fixedly connected to the mounting platform 5 via connecting rods 83. By adjusting the suspension cable 7, the angle of the mounting platform 5 can be changed. During this process, the rotating rod 82 rotates relative to the annular seat 81. This process is also stepless adjustment, further realizing fine adjustment to meet more experimental requirements.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution. In the absence of a conflict of solutions, the various technical features mentioned in each embodiment can be combined in any manner to form other implementation methods that can be understood by those skilled in the art.

[0100] In addition, without departing from the scope of the present invention, the technical solutions described in the aforementioned embodiments may be modified, or some of the technical features thereof may be replaced by equivalents, without causing the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
