The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings 1 to 4.
Example 1
A cement precast pile connecting member, comprising: go up fixed head 1, lower fixed head 2, first connecting piece 3 and second connecting piece 4, first connecting piece 3 is including consecutive first screw portion 31, toper portion 32 and joint 33, first screw portion 31 threaded connection is inside last fixed head 1, joint 33 diameter is greater than toper portion 32 bottom diameter, second connecting piece 4 includes second screw portion 41 and joint portion 42, second screw portion 41 threaded connection is inside lower fixed head 2, the vertical downward reduction of joint portion 42 cross-sectional diameter sets up, joint portion 42 terminal surface at least interval is provided with three group's flutings 421, the inside cylindricality guide hole 411 that is equipped with of second screw portion 41, the inside toper guide hole 422 that communicates with cylindricality guide hole 411 that is equipped with of joint portion 42.
As shown in fig. 1-4, the upper fixing head 1, the lower fixing head 2, the first connecting member 3 and the second connecting member 4 are made of conventional metal, and the utility model discloses a usage principle: it is fixed in a cement stake bottom to pour to go up fixed head 1, lower fixed head 2 is pour and is fixed in another cement stake bottom, fix in fixed head 1 first connecting piece 3 screw in, in fixed head 2 second connecting piece 4 screw in down, when two cement stakes are connected, the cement stake that has last fixed head 1 pushes down, make joint 33 of first connecting piece 3 get into in the toper guide hole 422 of joint 42 of second connecting piece 4, because be provided with fluting 421 on the joint 42, therefore joint 33 promotes joint 42 and outwards opens, until joint 33 is located joint 42 below completely, because joint 33 diameter is greater than toper 32 bottom diameter, consequently joint 33 can't upwards break away from joint 42, realize the connection of two cement stakes, the connection speed between the cement stake has been improved, it is more convenient to use.
