The insulating support device may be an insulating table, an insulating stand, an insulating frame, or the like, and is not limited herein. The present embodiment is explained by taking the insulating support device as an insulating table. In addition, the insulating support device is made of wood to prevent the detection result from being affected.

As shown in fig. 1, the insulating and supporting device comprises a table top 2 and two vertical legs 1 supporting the table top 2. Two landing legs 1 are arranged on two sides of the bottom of the table top 2 respectively to stably support the table top 2. It should be noted that the number of the table top 2 and the legs 1 and the connection manner therebetween are not specifically limited in this embodiment. For convenience of description, one of the legs 1 of the insulating and supporting device is set as a first structural member, and the table top 2 or the other leg 1 of the insulating and supporting device is set as a second structural member. Further, the insulation support device also comprises a connecting assembly 3. The first and second connecting members are fixedly connected by the connecting assembly 3, that is, the table top 2 and the leg 1 are fixedly connected by the connecting assembly 3. The present embodiment is explained by using the first structural member as the vertical leg 1 and the second structural member as the table top 2.

Specifically, referring to fig. 2, the leg 1 is provided with a first receiving hole 11 and a second receiving hole 12 which are communicated with each other. Alternatively, the central axis of the first receiving hole 11 is parallel to the thickness direction of the leg 1, and the central axis of the second receiving hole 12 is perpendicular to the thickness direction of the leg 1. Furthermore, a third containing hole 21 perpendicular to the thickness direction of the table top 2 is formed in the table top 2, and the third containing hole 21 is coaxial and communicated with the second containing hole 12.

The connection assembly 3 may optionally include an insulating screw 32 and an insulating nut 31 (see fig. 3). The insulating nut 31 is fixedly arranged in the first containing hole 11, and the insulating screw 32 is inserted into the third containing hole 21, penetrates through the second containing hole 12 and then is in threaded connection with the insulating nut 31, so that the table top 2 and the supporting leg 1 are fixedly connected. Furthermore, the end of the third accommodating hole 21 away from the second accommodating hole 12 is provided with an accommodating groove 211, and the head of the insulating screw 32 is located in the accommodating groove 211, so as to prevent the insulating screw 32 from protruding out of the table top 2 to affect the appearance or cause scratches. In this embodiment, the connection screw 32 is a cross flat head screw, and the head portion is provided with a cross sink groove (not shown), so that the screw can be screwed conveniently by using a relevant tool, the operation is convenient and labor-saving, and the accommodation groove 211 is also set to a corresponding shape, thereby preventing a large gap from being formed between the two, and preventing the appearance from being influenced. The receiving groove 211 may be correspondingly configured according to the specification of the connection screw 32.

In this embodiment, through inlaying insulating nut 31 and establishing landing leg 1 to the power that the connection position received is dispersed, improves the assembly firmness, and difficult not hard up, and easy dismounting. Furthermore, the central axis of the second accommodating hole 12 is perpendicular to the central axis of the first accommodating hole 11, that is, the central axis of the threaded hole 311 on the insulating nut 31 coincides with the central axis of the insulating nut 31, so that the connection direction of the insulating screw 32 and the insulating nut 31 is perpendicular to the connection direction of the insulating nut 31 and the supporting leg 1, the force applied to the connection part is dispersed to the maximum extent, and the connection structure is stable and is not easy to loosen. In other embodiments, the central axis of the first accommodating hole 11 and the central axis of the second accommodating hole 12 may be inclined, and accordingly, the axis of the threaded hole 311 in the insulating nut 31 and the axis of the insulating nut 31 are also inclined, as long as the fit between the insulating screw 32 and the connecting bolt can be ensured.

The first containing hole 11 is a cylindrical hole, and the insulating nut 31 is cylindrical, so that the processing is convenient, and the stress is uniform.

In order to ensure that the threaded hole 311 on the insulating nut 31 can be coaxial with the second accommodating hole 12 after the insulating nut 31 enters the first accommodating hole 11, an indicating structure 312 is arranged on the end surface of the insulating nut 31. Preferably, the indicating structure 312 is a groove structure opened on the end surface. The groove structure is arranged along the radial direction of the insulating nut 31, the extending direction of the groove structure is perpendicular to the central axis of the threaded hole 311, the levelness of the groove structure is guaranteed, and the coaxiality of the threaded hole 311 and the second containing hole 12 can be guaranteed, so that the structure is simple, and the operation is convenient. Obviously, the extending direction of the groove structure may be parallel to or form a certain included angle with the central axis of the threaded hole 311, as long as the threaded hole 311 and the second accommodating hole 12 are coaxial by measuring the angle of the groove structure. In addition to the groove structure described above, the indicator structure 312 may also be a labeled arrow parallel to the axis of the thread 311.

In this embodiment, for convenience of processing, the concave structure and the indication structure 312 are the same and both have a groove structure. Therefore, the groove structure not only serves to indicate whether the threaded hole 311 is coaxial with the second receiving hole 12, but also can be inserted into the groove structure by a screwdriver or other relevant tools when screwing the insulating screw 32, so as to fix the insulating nut 31, and facilitate screwing the insulating screw 32.

Furthermore, a hook structure can be arranged on the end face of the insulating nut 31, and when the insulating support device needs to be disassembled and assembled, the hook structure can be hooked by a tool, so that the insulating nut 31 can be taken out conveniently. The hook structure may be hinged with the insulating nut 31. In a normal state, the hook structure is rotated to be attached to the end face of the insulating nut 31; when it is desired to turn the insulating nut 31 outwardly, the hook structure is conveniently hooked by the relevant tool. Furthermore, an accommodating groove can be further formed in the insulating nut 31, and the hook structure is located in the accommodating groove and does not protrude out of the end face of the insulating nut 31, so that the appearance is attractive, and scratches can be prevented.

It should be noted that in other embodiments, the insulation nut 31 may be configured as a flat shaft structure, a hexagonal prism structure, or an octagonal prism structure. Accordingly, when the insulation nut 31 has a flat shaft structure, the first accommodation hole 11 may be provided with a flat hole structure; when the insulating nut 31 is a hexagonal prism structure, the first accommodating hole 11 may be a hexagonal prism hole or a cylindrical hole; when the insulation nut 31 has an octagonal prism structure, the first accommodating hole 11 may be an octagonal prism hole or a cylindrical hole, so as to prevent the insulation nut 31 from rotating in the first accommodating hole 11, and further improve the connection firmness.
