Adopt this kind of structure, when connecting two precast piles 3, can directly peg graft in the socket 2 of another precast pile 3 with the bayonet joint 1 of a precast pile 3, and at least under grafting state, prop up subassembly 5 and can act on fixture block 4 mutually to order about fixture block 4 and stretch out the periphery wall of bayonet joint 1 from inside to outside, and plug in the groove 211 that stops that corresponds, can accomplish the connection of two precast piles 3, the installation can be comparatively simple and convenient.

Specifically, the fixture block 4 and the plug 1 may be slidably connected, the plug end of the plug 1 and the socket 2 may have a plug channel 111 arranged along the plug direction (i.e. the axial direction of the plug 1), the peripheral wall of the plug channel 111 may have at least one mounting hole 112, the fixture blocks 4 and the mounting holes 112 may be in a one-to-one correspondence relationship, and each fixture block 4 is at least partially located in the mounting hole 112; the expanding assembly 5 may include a first elastic member 51 and a pushing block 52, one end of the first elastic member 51 may abut against the pushing block 52 to provide an elastic force for the pushing block 52, and the pushing block 52 may have a tapered pushing surface 521, where at least when the plug 1 and the socket 2 are in a plugging state, the tapered pushing surface 521 may abut against the latch 4 to push the latch 4 to extend.

In fact, the tapered pushing surface 521 can interact with more than one fixture block 4, as shown in the figure, it can drive a plurality of fixture blocks 4 to extend out at the same time, that is, the embodiment of the present invention can only adopt one set of opening assembly 5 to drive a plurality of fixture blocks 4 to move, which is also beneficial to simplify the structure of the pile connecting mechanism.

In a first scheme, the spreading assembly 5 may be installed in the plug 1, and the structure at this time may refer to fig. 1 and fig. 2, and the spreading assembly 5 may be disposed in the insertion channel 111 to directly act on each fixture block 4, and under such a condition, even in a non-insertion state, each fixture block 4 may still extend out under the action of the spreading assembly 5.

For convenience of description, the precast pile 3 where the plug 1 is located may be referred to as a first precast pile, and the precast pile 3 where the socket 2 is located may be referred to as a second precast pile.

In view of the above, the wall surface (the lower wall surface in fig. 1 and 2) of the portion of each fixture block 4 extending out of the outer peripheral wall of the plug 1, which is far from the first precast pile, may have a guide surface that is inclined gradually from inside to outside toward the first precast pile, so that, during the plugging process, the guide surface may act on the inner peripheral wall of the plugging portion 21 to drive the fixture block 4 to overcome the elastic force of the propping assembly 5 and retract inwards into the mounting hole 112, thereby preventing the insertion of the plug 1 from being blocked.

It should be noted that, for the fixture block 4 and the mounting hole 112, the definitions of "inside" and "outside" are relative to the central axis of the connector 1, the direction relatively close to the central axis of the connector 1 is inside, and the direction relatively far away from the central axis of the connector 1 is outside.

Of course, the support portion 113 may not completely close the lower end opening, which does not affect the function of supporting the first elastic member 51.

The first elastic member 51 may provide a pushing force when it interacts with the pushing block 52, and may also provide a pulling force, which is particularly related to the installation position of the pushing block 52. When providing the pulling force, two ends of the first elastic element 51 are respectively connected with the pushing block 52 and the supporting portion 113, and at this time, the first elastic element 51 may also be an elastic element in the form of a pulling rope or the like; in the solution of the accompanying drawings, the first elastic element 51 provides an elastic pushing force, and preferably, even in the inserted state, the first elastic element 51 may still be in a compression deformation state, which is beneficial to ensure the action effect of the pushing block 52 on each fixture block 4.

With reference to fig. 2, the inserting channel 111 may be a stepped groove, and along a direction close to the first precast pile, the stepped groove may include a large neck and a small neck, and the pushing block 52 may specifically include a tapered expanding portion and a guide rod portion connected to the tapered expanding portion, wherein the tapered expanding portion and the first elastic member 51 may be installed in the large neck, and the guide rod portion may be inserted into the small neck, so as to guide the axial displacement of the pushing block 52, and further avoid the side turning of the pushing block 52 during the use to a greater extent.

In the second scheme, the spreading assembly 5 may be installed in the inserting seat 2 (this scheme is not shown in the drawings), and at this time, the lower end of the inserting channel 111 may have an opening, and when two precast piles 3 are connected, along with the continuous insertion of the inserting head 1, the pushing block 52 may extend into the inserting channel 111 and contact with each fixture block 4, and then under the action of the first elastic member 51, the pushing block 52 may push out the fixture block 4.

In this embodiment, in the non-plugging state of the plug 1, each latch 4 can be retracted into each mounting hole 112, that is, only in the plugging state, each latch 4 extends out from each mounting hole 112.

In comparison, the two solutions can both achieve the function of the spreader component 5 interacting with the fixture block 4 to push out the fixture block 4 in the corresponding mounting hole 112, and in practical application, those skilled in the art can set the spreader component according to actual needs. It specifically arrives the embodiment of the utility model provides a, the preferred first scheme that adopts props up subassembly 5 and can install in bayonet joint 1, and this moment, it is higher to prop up the reliability when subassembly 5 and each fixture block 4 act on mutually.

Further, at least the portion (i.e. the outer end portion) of each fixture block 4 away from the central axis of the plug 1 is a tapered conical portion 41 in the direction away from the central axis of the plug 1, and at least the hole (i.e. the outer hole) of the mounting hole 112 located on the outer peripheral wall of the plug 1 may be provided with a limiting structure to form a barrier with the conical surface of the conical portion 41, so that the fixture block 4 can be prevented from being disengaged from the mounting hole 112 under the action of the spreading assembly 5 to a greater extent.

The limiting structure may be a necking structure, that is, a hole section of the mounting hole 112 far from the central axis of the plug 1 may be a hole section with a gradually reduced radial dimension, so as to form a limiting fit with the conical portion 41. Alternatively, the limiting structure may be a limiting member in the form of a limiting protrusion 112a, a limiting block, or the like, provided at the outer orifice of the mounting hole 112, so that the limiting structure can also be in limiting engagement with the tapered portion 41.

Further, the dynamic friction factor μ of the contact surface of the latch 4 with the latching groove 211 may be defined, and specifically, the dynamic friction factor μmay be set to be greater than or equal to a tangent value of the angle θ between the contact surface and the reference surface, i.e., μ ≧ tan θ. The reference surface is a surface perpendicular to the central axis of the connector 1, and in a specific practice, when the two precast piles 3 are vertically arranged, the reference surface may be a horizontal surface.

So set up, can be so that fixture block 4 and the dead groove 211 between form the dynamic friction auto-lock to realize the function of pegging graft stopping, pass through at two precast piles 3 the utility model provides an elasticity pile extension mechanism connects after, two precast piles 3 are difficult for separating, and the reliability of pile extension is higher.

In addition, the dynamic friction self-locking formed between the fixture block 4 and the clamping groove 211 can ensure that the plug-in connector 1 cannot be pulled out of the plug-in connector 2 unless the plug-in connector 1 or the plug-in connector 2 is directly damaged, so that the anti-pulling performance between the two precast piles 3 is ensured, no matter whether the fixture block 4 is completely positioned in the clamping groove 211 or not, as long as at least part of the fixture block 4 is in contact with the clamping groove 211. Moreover, in the process of inserting so as to gradually enter the clamping block 4 into the clamping groove 211, if a pulling force is applied to the precast pile 3 provided with the inserting joint 1, because the dynamic friction between the clamping block 4 and the clamping groove 211 is self-locked, relative movement between the clamping block 4 and the clamping groove 211 cannot occur, so that axial backward movement cannot occur between the two precast piles 3, that is, the two precast piles 3 can only be continuously inserted; after the 3 terminal surfaces of two precast piles offset, bayonet joint 1 can not continue to insert, and at this moment, fixture block 4 gets into completely and stops in the groove 211, perhaps, the fixture block 4 contacts with the last contact surface at least part that stops between the groove 211, and at this moment, can't extract between two precast piles 3, also can't continue to insert to the joint line who has significantly reduced between two precast piles 3 reduces the error of the connection straightness accuracy between two precast piles 3, has improved the connection stability after sinking the stake.

Here, the embodiment of the present invention does not limit the number, structure and installation position of the locking grooves 211, and specifically needs to correspond to the number, structure and installation position of the locking blocks 41; taking the scheme in the drawings as an example, when the number of the latch blocks 4 is plural and each latch block 4 is installed at the same height, only one latching groove 211 may be provided, and at this time, the latching groove 211 may be an annular groove so as to be matched with each latch block 4 at the same time.

The plug 1 may include a plug rod 11 and a mounting seat 12, the mounting seat 12 may be installed on the first precast pile, an end of the plug rod 11 may be installed on the mounting seat 12, and particularly, the plug rod 11 and the mounting seat 12 may be fixedly connected by welding, screwing, or the like. Of course, the connector 1 may also comprise only the above-mentioned connection rod 11, in which case the connection rod 11 would be connected directly with its end to the first pre-pile.
