Description

A pipe mold bolt connection structure

technical field

The utility model relates to a connection structure of a pipe mold, in particular to a bolt connection structure connecting an upper mold and a lower mold of a pipe mold.

Background technique

The mold of the cement pipe pile for construction needs to be fixed and connected with bolts after the mold is closed. The traditional pipe mold bolt connection structure is to install the connecting bolts under the pipe mold, and then turn over the upper mold and then tighten it. This connection structure has the above disadvantages: it is labor-intensive, and it is easy to break the thread when turning it up, causing damage to the bolts, and the assembly efficiency of this connection structure is relatively low.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a pipe mold bolt connection structure with high installation efficiency and which can prevent bolts from being damaged.

The technical scheme that the utility model solves its technical problem adopts is:

A pipe mold bolt connection structure, comprising an installation hole arranged in the upper mold, a screw hole arranged in the lower mold, and a bolt inserted in the installation hole and threadedly connected with the screw hole, characterized in that the bolt is installed with For the outer spring clip, an inner spring clip is installed in the mounting hole, and a spring is set on the bolt between the outer spring clip and the inner spring clip, and a bolt head is installed at the mounting hole.

As a preferred embodiment of the present invention, the bolt head is installed in the installation hole; the bolt head is threadedly connected with the installation hole.

As a preferred embodiment of the present invention, the bolt head is installed on the upper die at the installation hole; the bolt head and the upper die are threaded.

The beneficial effects of the utility model are: after the upper mold and the lower mold of the pipe mold are disassembled, the bolts of the bolt connection structure are suspended on the upper mold through the bolt head and the outer spring clip, and the thread of the bolt is located in the upper mold, The screw thread will not be damaged after the mold is removed; when the mold is closed, the upper mold and the lower mold can be aligned and screwed on. The bolts are easy to operate and the assembly efficiency is high.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model first embodiment;

Fig. 2 is a schematic structural view of another embodiment of the present invention.

Detailed ways

With reference to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of the utility model, in the embodiment shown in the figure, this pipe mold bolt connection structure, comprises the installation hole 2 that is arranged in the upper die 1, is arranged on the lower die 3 The screw hole 4 inside and the bolt 5 that is inserted in the mounting hole 2 and can be threadedly connected with the screw hole 4, wherein an outer spring clip 6 is installed on the bolt 5, an inner spring clip 7 is installed in the mounting hole 2, and the outer spring clip A spring 8 is set on the bolt 5 between the 6 and the inner spring clip 7, and a bolt head 9 is installed in the installation hole 2, and a screw connection can be adopted between the bolt head 9 and the installation hole 2, so as to facilitate replacement of the bolt.

When the upper mold and the lower mold of the pipe mold are disassembled, the spring pushes the outer spring clip, and the outer spring clip is in contact with the bolt head. The bolts of this bolt connection structure are suspended on the upper mold through the bolt head and the outer spring clip. Moreover, the thread of the bolt is located in the upper mold, and the thread will not be damaged after the mold is removed; when the mold is closed, the upper mold and the lower mold can be aligned and the bolts are screwed on, which is convenient for operation and high in assembly efficiency.

Referring to Fig. 2, Fig. 2 is a schematic structural view of another embodiment of the present invention, which is basically the same as the above embodiment, except that the bolt head 9 is installed on the upper mold 1 at the installation hole 2, and the bolt The sealing head 9 is threadedly connected with the upper mold 1 .
