Each position adjustment assembly is composed of an extension rod 2 and a movable joint 3, and several position adjustment assemblies are connected end-to-end through the extension rod and the movable joint to adjust the spatial position of the heating element. In a specific embodiment, the extension rod is cylindrical. Fig. 2 is a structural schematic diagram of the movable joint in the spatial position adjustment device of the present invention. Among them, the movable joint 3 is composed of more than four rotating disks 4 coaxially pierced and fixed together. The center of the rotating disk of the movable joint is provided with a hole for fastening bolts. The other side of the slightly smaller semi-cylindrical groove is provided with an anti-slip texture to prevent sliding with the side of the opposite rotating disk 4 . The opposite sides of every two adjacent rotating disks 4 have semi-cylindrical grooves respectively to form an integral cylindrical groove, and one end of the extension rod 2 of each position adjustment assembly passes through the cylindrical groove of the movable joint; wherein, the first position One end of the first extension rod 2 of the adjustment assembly is threaded and connected to the internal thread hole of the installation base 1, and the other end of the first extension rod 2 passes through the first groove of the movable joint 3; the second end of the second position adjustment assembly One end of the extension rod 2 is passed through and fixed in the second groove of the movable joint 3 of the first position adjustment assembly; the other end of the second extension rod 2 of the second position adjustment assembly is passed through and fixed in the first recess of the third position adjustment assembly. In the groove, the connection of subsequent position adjustment components is carried out in sequence. The first groove and the second groove are respectively arranged on opposite sides of every two rotating disks among the four rotating disks.

The other side of each movable turntable 4 without semi-cylindrical grooves is provided with fan-shaped anti-skid textures. The discs are locked in series through the central bolt. When the connecting bolts are tightened, the rotating disc locks the extension rod and the rotating discs are pressed against each other through anti-slip textures without mutual rotation. When the central connecting bolt is loosened, the gap between the rotating disks 4 increases, so that the movable joint 3 can slide and rotate axially along the extended rod 2 passing through, and the two or more extended rods 2 connected by the movable joint 3 The angle between them is adjustable.

在一实施方式中，除螺栓外，整个装置可采用高强度硬铝加工而成，内螺纹镶嵌钢丝螺套。若加热元件质量较大，延长杆2延伸距离较远，为保证结构强度和刚度，可采用不锈钢加工。加工完的结构应进行无油处理。In one embodiment, except for the bolts, the entire device can be made of high-strength duralumin, and the inner thread is embedded with a wire screw sleeve. If the mass of the heating element is large, the extending distance of the extension rod 2 is relatively long. In order to ensure the structural strength and rigidity, stainless steel can be used. Finished structures should be treated oil-free.
通过多个延长杆和活动关节的组合使用，可使延长杆绕开各种空间干涉物到达预定安装位置，并将真空热试验中所用红外灯等加热元件安装固定于延长杆上。Through the combined use of multiple extension rods and movable joints, the extension rod can bypass various space interference objects to reach the predetermined installation position, and install and fix heating elements such as infrared lamps used in the vacuum thermal test on the extension rod.
尽管上文对本发明的具体实施方式给予了详细描述和说明，但是应该指明的是，我们可以依据本发明的构想对上述实施方式进行各种等效改变和修改，其所产生的功能作用仍未超出说明书及附图所涵盖的精神时，均应在本发明的保护范围之内。Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be pointed out that we can make various equivalent changes and modifications to the above-mentioned embodiments according to the concept of the present invention, and the functional effects produced by it are still the same. Anything beyond the spirit contained in the specification and drawings shall fall within the protection scope of the present invention.
