The technical scheme for solving the technical problems is as follows: fixing the handrail on the adjacent wall body with the opening through a fixing device; the fixing device is as follows: the expansion bolts are driven into the wall bodies near the sides, the fixing plates are arranged at the ends, extending out of the wall bodies near the sides, of the expansion bolts, the fixing clamps are arranged on the fixing plates, and the railings are fixed between the fixing plates and the fixing clamps.

The utility model discloses a fixed plate does: the fixed plate body is the bellied circular slab of one end, and fixed plate body central point puts the processing and has the expansion bolt hole, and the protruding end of fixed plate body passes through the expansion bolt hole and installs on expansion bolt, and the symmetry processing has two fixed orificess on the fixed plate body, and fixed plate body plane end central point puts radial processing spacing groove, and the central line of spacing groove is parallel with the railing.

The utility model discloses a spacing groove is rectangular channel or arc wall.

The utility model discloses a fixing clip does: the fixing clamp body is formed by connecting a semicircular rod and a straight rod arranged at two ends of the semicircular rod into a whole, an external thread is processed at the tail end of the straight rod, and a limit nut is installed on the straight rod.

The utility model discloses a be provided with flexible liner between fixed plate and the fixing clip.

Because the utility model discloses an enter expansion bolts in the wall body, expansion bolts's the wall part that stretches out installs the fixed plate, processing has the fixed orifices on the fixed plate, semi-circular fixing clip blocks the railing and the end of fixing clip stretches into the fixed orifices and fixes with screw fastening connecting piece, can set up flexible liner between semi-circular fixing clip and the railing, a frictional force for increasing between the two, can fix the railing on the wall body through the device, site constructor can not move the railing at will, the operation personnel also can directly detain safety button and carry out outdoor construction back on the railing, guarantee construction safety, can popularize and apply to the room and build the construction and face limit entrance to a cave protector or equipment technical field.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples, but the present invention is not limited to these examples.

Example 1

In fig. 1, the fixing device for the near-edge cave entrance handrail of the utility model fixes a handrail 2 on a near-edge wall body 1 with a cave entrance through a fixing device 3; the field constructor can not move the railing at will, thereby playing a role of safety protection and improving the construction safety.

In figure 2, a fixing device 3 is formed by connecting an expansion bolt 3-1, a fixing plate 3-2, a fixing clip 3-3 and a flexible liner 3-4, the expansion bolt 3-1 is driven into an adjacent wall body 1, one end of the expansion bolt 3-1 extending out of the adjacent wall body 1 is fixedly connected with the fixing plate 3-2, the fixing clip 3-3 is arranged on the fixing plate 3-2, a railing 2 is fixed between the fixing plate 3-2 and the fixing clip 3-3, and further the flexible liner 3-4 is arranged between the fixing plate 3-2 and the fixing clip 3-3, so that the friction force between the fixing plate 3-2 and the fixing clip 3-3 is increased, and the connection stability is improved.

In fig. 3, the fixing plate 3-2 of this embodiment is composed of a fixing plate body 3-2-1, the fixing plate body 3-2-1 is a circular plate with a convex end, an expansion bolt hole a is processed at the center of the fixing plate body 3-2-1, the convex end of the fixing plate body 3-2-1 is installed on the expansion bolt 3-1 through the expansion bolt hole a, two fixing holes b are symmetrically processed on the fixing plate body, the fixing clip 3-3 is installed in the fixing hole b, a limiting groove c is radially processed at the center of the planar end of the fixing plate body 3-2-1, the center line of the limiting groove c is parallel to the balustrade 2, the limiting groove c may be an arc groove or a rectangular groove, and the shape of the limiting groove c is determined according to the shape of the balustrade 2.
