The utility model adopts the following technical means:

a multi-clamping-position right-angle locking device comprises a fixed plate, wherein a rotating plate is arranged on one side face of the fixed plate, a rotating hole is formed in the rotating plate, a circular arc-shaped rotating groove which takes the rotating hole as a circle center is further formed in the rotating plate, and clamping grooves are formed in positions close to two ends of the circular arc-shaped rotating groove.

Preferably, the clamping groove is of a groove-shaped structure extending along the direction departing from the rotating hole on one rotating groove, and the clamping groove is semicircular.

Preferably, the clamping grooves close to the two ends of the rotating groove are respectively 90 degrees away from the connecting line of the rotating hole, and the central angle corresponding to the arc-shaped rotating groove with the rotating hole as the center of the circle is larger than 90 degrees.

Preferably, the fixing plate is further provided with a fixing hole.

Compared with the prior art, the utility model has the advantages of as follows:

the utility model can limit the rotation of the clamping structure matched with the clamping groove through the arc-shaped rotating groove, thereby ensuring safer use; and the arc-shaped rotating groove can provide force support when being locked, so that the clamping groove can be arranged shallower, the locking process can be easily matched and released, and the safety of the force locking process is ensured.

Detailed Description

As shown in fig. 1-2, the following examples are provided.

As shown in fig. 1, the multi-clamping right-angle locking device comprises a fixed plate 1, wherein a fixed hole 2 is further formed in the fixed plate 1, a rotating plate 3 is arranged on one side surface of the fixed plate 1, a rotating hole 4 is formed in the rotating plate 3, a circular arc-shaped rotating groove 5 with the rotating hole 4 as a circle center is further formed in the rotating plate 3, and clamping grooves 6 are formed in positions close to two ends of the circular arc-shaped rotating groove 5. Thus, as shown in fig. 2, the fixed plate 1 can be fixedly connected with a device to be rotated, and the fixed plate 1 and the rotating plate 3 are rotated to drive the device connected with the fixed plate 1 to rotate by rotating the rotating hole 4 and a fixing device 7, and taking the rotating hole 4 as a rotating fulcrum. In order to enable more stable rotation, an external fixing rod 8 capable of controlling up-and-down movement is usually placed in the rotating groove 5, during the rotation, when the rotation is not needed, the fixing rod 8 is placed in the blocking groove 6 at one end, when the rotation is needed, the fixing rod 8 is controlled to move upwards, the fixing plate 1 and the rotating plate are rotated, and when the fixing rod 8 reaches the blocking groove 6 at the other end, the fixing rod 8 is controlled to move downwards to the other blocking groove 6, and the locking is completed. Certainly, in order to facilitate locking, the external fixing rod 8 moves up and down to complete releasing and locking, the up-and-down movement mode is not limited, the fixing rod 8 can be independent, the up-and-down movement of the fixing rod 8 is completely realized through manpower, or an elastic device is arranged at the upper part or the lower part of the fixing rod 8, so that the elastic device is in a compressed state when the fixing rod 8 moves up, in the whole process of releasing and locking, only the fixing rod 8 needs to be moved up through manpower, and when the fixing rod 8 reaches another clamping groove 6, the fixing rod 8 can be conveyed into the clamping groove 6 through the elastic force of the elastic device, and the locking is automatically realized.

As shown in figure 1, the locking groove 6 is a groove-shaped structure extending along the direction departing from the rotating hole 4 on one rotating groove 5, and the locking groove 6 is semicircular. When the fixing rod 8 is clamped in the clamping groove 6, the fixing rod 8 is locked in the clamping groove 6 more easily by means of the arc-shaped rotating groove 5, so that the clamping groove 6 is designed into a semicircular structure, the fixing rod 8 can be safely locked, and meanwhile, the fixing rod 8 can enter and exit the clamping groove 6 to be locked more conveniently.

And as shown in fig. 2, the clamping grooves 6 close to the two ends of the rotating groove 5 are respectively 90 degrees with the connecting line of the rotating hole 4, and the central angle corresponding to the arc-shaped rotating groove 5 taking the rotating hole 4 as the center of the circle is more than 90 degrees. Of course, the position of the blocking groove 6 can be set to 90 ° according to actual needs, so as to meet the actual needs. Thus, in one embodiment, the fixing plate 1 can be rotated to locate the fixing rod 8 at the end of the rotating groove 5, the movement of the fixing rod 8 is limited by the rotating groove 5, the fixing rod 8 can be in a state of waiting for locking without using more external force, and when locking is needed, the locking can be immediately performed because the clamping groove 6 is close to the end of the rotating groove 5, so that the locking device can be applied in a wider range of situations.
