Description
Technical Field
The utility model relates to a combination fixture field especially relates to a rotatory round pin combination fixture structure of cross.
Background
The combined clamp is of a plug type and a plug plate type, and the plug plate type combined clamp not only has the function of connecting the template, but also can be inserted into opposite penetrating pull rods except for installing the template to bear the lateral pressure of newly cast concrete, but also increases the difficulty for rolling the template frame. At present, a combined clamp which is fast in assembly and disassembly, firm and reliable is urgently needed to fix the template.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect with not enough, provide a rotatory round pin combination fixture structure of cross, adopt the utility model discloses a structure, install and remove fastly, the reliability wall, practical value is high, has reduced labour cost.
In order to achieve the above object, the utility model adopts the following technical scheme: a cross rotating pin combined clamp structure comprises a cylindrical pin, a key pin, a spring washer and a handle; the cylindrical pin is of a cylindrical structure, the most end part of the cylindrical pin is a circular truncated cone with a gradually-reduced diameter, the head of the cylindrical pin is provided with a pin hole, a key-type pin is fixed in the pin hole, the cylindrical pin and the key-type pin form a cross shape, the tail of the cylindrical pin is welded with a handle, and a spring washer is sleeved at the joint of the handle and the cylindrical pin.
Preferably, the end of the handle is provided with a circular hole.
The utility model has the advantages that: adopt the utility model discloses a structure, install and remove fastly, the reliability wall, practical value is high, has reduced labour cost.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention.
Fig. 1 is a schematic structural view of a cross-shaped rotating pin combined clamp.
Fig. 2 is a schematic view of the combination fixture in use.
Wherein: the template comprises a cylindrical pin 1, a key-type pin 2, a spring washer 3, a handle 4, a first template 5, a second template 6, a butterfly-shaped hole 7, a pin hole 1-2 and a round hole 4-1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings 1-2.
As shown in fig. 1-2, a cross-shaped rotating pin combined clamp structure comprises a cylindrical pin 1, a key-type pin 2, a spring washer 3 and a handle 4; the cylindrical pin 1 is of a cylindrical structure, the most end part of the cylindrical pin 1 is a circular truncated cone with a gradually-reduced diameter, the head of the cylindrical pin 1 is provided with a pin hole 1-2, a key-type pin 2 is fixed in the pin hole 1-2, the cylindrical pin 1 and the key-type pin 2 form a cross shape, the tail of the cylindrical pin 1 is welded with a handle 4, and a spring washer 3 is sleeved at the joint of the handle 4 and the cylindrical pin 1.
In specific implementation, a round hole 4-1 is formed in the end portion of the handle 4.
During actual operation, butterfly-shaped holes 7 are formed in the first template 5 and the second template 6, each butterfly-shaped hole 7 is composed of a middle round hole and wing holes on two sides, the cross shape formed by the cylindrical pin 1 and the key-type pin 2 is matched with the corresponding butterfly-shaped hole 7, when the fixing device is used, the cross-shaped head is firstly inserted into the butterfly-shaped holes 7 which are overlapped in pairs of the first template 5 and the second template 6, then the first template 5 and the second template 6 can be fixed by rotating the handle 4 by 90 degrees, and otherwise the fixing device can be detached.
