Description

Anti-lift connectors and their uses

The present invention relates to an anti-lift connector and its use; in particular, to an anti-lift connector for constructing a raised floor, which has high bearing capacity and high shock resistance, and can resist the effect of upwardly disengaging the connecting structure in the event of vibration, for example and its uses.

Today, raised floors have been widely used in computer rooms, clean rooms and other places, with functions such as providing a high flat surface, improving space utilization, and shock resistance. The inventor has been engaged in the research of related products for many years, and has developed many patents, among which there are many studies on the seismic resistance of the scaffold structure of the raised floor. For the convenience of description, the following four references are roughly used to describe the improvement process of the connection structure of the tripod.

Reference 1: Republic of China Patent No. 543722.

As shown in Figures 3 to 5 of the drawings of Reference 1, in Reference 1, the inventor improved the connection structure for connecting the steel column (18) and the screw (23). The improved connection structure is an anti-lifting nut, which can be assembled by a nut bushing (10) and a steel groove ring (11) and fixed by welding. Using the nut bushing (10) and the steel groove ring (11) to cooperate with the steel bearing plate (19) can effectively improve the bearing capacity, and use the fixing screw (16) to lock the steel groove ring (11), which can further improve the bearing capacity And increase the shock resistance. The described [anti-lift] effect mainly refers to the resistance to, for example, vibration. The effect of the force of the anti-lift nut upwards off the steel column (18).

However, the nut bushing and the steel groove also need to be welded firmly, and when the two are used together with the steel support plate, there is also a problem that the steel support plate and the steel column also need to be welded firmly. Therefore, the invention disclosed in Reference 1 has problems such as a large number of components and complicated assembly and processing.

Reference 2: Republic of China Patent No. 545498.

As shown in the third figure of the drawing of Reference 2, in Reference 2, the inventor mainly aimed to improve the support plate of the tripod connected to the floor unit, but the inventor also improved the connecting support tube (10) and the screw. The connection structure of (18). The improved connection structure is a screw hole seat (13). The integrally formed screw hole seat (13) is used with other components to connect the support tube (10) and the screw (18), which not only maintains high bearing capacity and high shock resistance, but also saves the number of components in Reference 1. And the trouble of cumbersome assembly and processing.

However, the solid structure in which the screw hole seat is integrally formed will have problems such as high cost and heavy weight when, for example, a support tube with a larger diameter and/or a screw with a smaller diameter needs to be used.

Reference 3: Republic of China Patent No. M470137.

As shown in FIGS. 1 to 2 of Reference 3, in Reference 3, the inventors improved the connection structure for connecting the support tube (1) and the screw (41). The improved connection structure can be composed of a tube cover (2) and a positioning tube body (3). By using the pipe cover (2) and the positioning pipe body (3) to cooperate with other components, the effect of easy disassembly and assembly can be increased, and the material cost can be saved.

However, the easily detachable cap and the positioning tube only have the effect of supporting the pressure from above, and do not provide resistance to the cap in the event of vibration, for example. The effect of the force of the upward disengagement from the supporting tube body.

Reference 4: Republic of China Patent No. M559967.

As shown in Figures 2 to 3 of Reference 4, in Reference 4, the inventor mainly provided the technology for supporting and positioning the equipment base (101) and equipment (103), but the inventor also improved the connection sleeve at the same time The connection structure of the pipe (3) and the fixing bolt (6). The improved connecting structure is a connecting piece (4). Using the connector (4) to cooperate with other components to connect the sleeve (3) and the fixing bolt (6), not only maintains high bearing capacity and high shock resistance, but also saves the trouble of a large number of components and complicated assembly and processing. , It can also reduce the amount of material to solve the problems of too high cost and too heavy weight.

However, the connector is an integrally formed structure, so there is a problem of high processing cost.

From References 1 to 4, it can be seen that the connection structure of the tripod can be subdivided into connections with anti-lifting effect (the anti-lifting effect refers to the effect of resisting the force that makes the connection structure upward from the supporting tube body during vibration, for example) structures (as shown in refs 1, 2, 4) or without linking structures (as shown in ref 3) that do not have anti-lifting efficacy. The connecting structure with anti-lift effect can be called anti-lift connector, and the conventional anti-lift connector obviously still has room for improvement.
