Abstract

The utility model discloses a rotary type refractory brick clamp apparatus which mainly consists of a rotary pin shaft, a clamping plate and a limit part; the rotary pin shaft is connected in the clamping plate in a penetrating manner, the position of the middle part of the rotary pin shaft, close to the head end, is provided with an incomplete rotary groove, the head end of the rotary pin shaft is provided with a rotary limiting head, the part of the limit part, stretching into the rotary groove, is movably clamped with the rotary limiting head. In the utility model, the limit part is movably clamped with the rotary limiting head, the problem that a refractory brick is inconvenient to replace owning to rusting easily is effectively solved, so that the replacement is high-efficiency and rapid.

Description

Rotary refractory brick jig

Technical field

The utility model relates to a kind of jig, particularly renews the movable fixture that solves the difficulty of dismounting in the brickwork preface and design for ease of the refractory brick maintenance and with second-hand brick.

Background technique

Fixedly adopt fixedly brick body of bolt type in the fireplace both domestic and external during refractory brick usually, a difficult problem can discharge some corrosive gass when being the fireplace burning, the long-term bolt of invading, bolt produces corrosion, bonding securely as a whole with iron rust, in case need the new refractory brick of transposing, must rotate bolt earlier and could change new brick, but bolt extremely difficulty unclamps, even twists off screw rod.

The model utility content

Technical problem to be solved in the utility model provides a kind of plug-in type refractory brick jig at above deficiency exactly, and this jig is rotary limit structure, design ingenious, the refractory brick that can more renew quickly and easily.

Technical solution adopted in the utility model is:

A kind of rotary refractory brick jig, mainly constitute by rotary pin shaft, clamp and bounding means, the rotary pin shaft cross-under is in clamp, the rotary pin shaft middle part is provided with non-complete spin slot near the position of head end, the head end of rotary pin shaft has the rotation positioning head, and bounding means stretches into the part and a rotation positioning activity clamping of spin slot.

The rotation positioning head is that to be the horizontal of side cutting coniform.

Rotary pin shaft and clamp are Spielpassung.

Also be provided with spring sheet between rotary pin shaft and the clamp.

Bounding means vertically is screwed in the clamp, and activity is stretched in the spin slot.

The beneficial effect that the utility model can reach is:

1, the utility model is simple in structure, but designs ingenious, convenient to use.

2, a utility model bounding means and rotation positioning activity clamping has solved the problem that refractory brick is changed in the inconvenience that causes because of easily getting rusty effectively, makes to change to become rapidly efficient.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of rotary pin shaft is to view.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing:

As Fig. 1, shown in Figure 2: the rotary pin shaft 10 gap cross-under of this rotary refractory brick jig are in clamp 30, rotary pin shaft 10 middle parts are provided with non-complete 360 ° spin slot 11 near the position of head end, the head end of rotary pin shaft 10 has rotation positioning 12, rotation positioning 12 is coniform for the horizontal that is side cutting, cutting position and spin slot 11 bottom levels, bounding means 40 vertically is screwed in the clamp 30, and activity is stretched in the spin slot 11, bounding means 40 stretches into the part and rotation positioning 12 an activity clamping of spin slot 11, also is provided with spring sheet 20 between rotary pin shaft 10 and the clamp 30.When changing refractory brick, only need level to extract rotary pin shaft 10 out, change refractory brick, insert rotary pin shaft 10 then, Rotate 180 °, the part that makes bounding means 40 stretch into spin slot 11 has promptly been finished whole process with rotation positioning 12 clamping.
