The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example one

Referring to fig. 1, the utility model discloses an eccentric nail, include:

the body 1, preferably, in this embodiment, the body 1 is a fixing rod with a spike at the lower end.

The adjusting part 2 comprises an eccentric table 21 and a guide column 22, the eccentric table 21 is arranged at the top end of the body 1, the guide column 22 is arranged at the top of the eccentric table 21, and particularly, the central axis of the guide column 22 is not collinear with the central axis of the body 1 and is perpendicular to the eccentric table 21 respectively.

Preferably, the eccentric table 21 of the present embodiment is a polygonal square table, preferably, the number of sides of the polygonal square table is six, and preferably, the polygonal square table is a regular hexagon, and the purpose of the present invention is to: after the body 1 is nailed into a fixed object, the regular hexagon eccentric table 21 has the same structure with a conventional screw head, so that tools such as an open clamp and the like can be clamped and rotated more conveniently; in this embodiment, the central axis of the body 1 is aligned with the center of the bottom surface of the hexagonal eccentric table 21.

In addition, the eccentric table 21 may be, but is not limited to, circular, rectangular, or square.

Otherwise, in order to improve the fixing effect of the body 1 and the fixture, the periphery of the body 1 is provided with threads, so that it can be understood that the body 1 and the fixture are in threaded connection.

Further, still include guide buffer portion 3, guide buffer portion 3 includes guide pulley 31 and buffer 32, and guide pulley 31 rotates and sets up on guide post 22, because guide pulley 31 is used for the joint in outside moving part to carry out the orbit spacing to it when outside moving part moves, consequently, guide pulley 31 can receive and come from outside moving part impact, so, buffer 32 one end is connected in guide pulley 31, and the other end is connected in eccentric platform 21.

Preferably, the buffer member 32 is a spring, and the spring is sleeved on the guide post 22 and is located between the guide wheel 31 and the eccentric table 21, and the guide wheel 31 of the embodiment has a structure with a large upper end and a small lower end.

In other embodiments, the buffer 32 can be, but is not limited to, a spring, and similarly, one end of the spring is connected to the guide wheel 31, and the other end is connected to the eccentric table 21.

In particular, in order to avoid the damage to the buffer member 32 caused by the open ended pliers being clamped to the bottom end of the buffer member 32 when the open ended pliers are clamped on the eccentric table 21, in this embodiment, the bottom of the guide post 22 is annularly provided with the cylindrical isolation table 5, and one end of the buffer member 32 far away from the guide wheel 31 abuts against the top surface of the isolation table 5.

In addition, the guide wheel 31 is clamped with the external moving part, and under the condition that the external moving part moves for a long time, the friction between the external moving part and the guide wheel 31 makes the abrasion of the guide wheel 31 unavoidable, so that the guide wheel 31 needs to be replaced.

Example two

Referring to fig. 2, the eccentric pin of the first embodiment is applied to a door and window system, and this embodiment is exemplified by a double-stroke sliding door, and it can be known that the sliding door includes two door leaves 6 and a lower wheel 7 disposed at the bottom of the door leaves 6.

At least one clamping groove 8 for clamping the guide wheel 31 is formed in the bottom of the door leaf 6, and buffering protrusions 9 are oppositely arranged on two sides of the clamping groove 8, where it should be noted that the width of the clamping groove 8 is greater than or equal to the maximum diameter of the guide wheel 31, preferably, in this embodiment, the width of the clamping groove 8 is slightly greater than the maximum diameter of the guide wheel 31; the minimum distance between the two buffering bulges 9 is smaller than the maximum diameter of the guide wheel 31 and larger than the diameter of the limiting circular truncated cone.

The installation process of the eccentric nail is as follows: firstly, through measuring and calculating the mounted position of door leaf in order to confirm the position of draw-in groove 8, set up the screw in the below of draw-in groove 8 central line position, specifically, two door leaves 6 correspond two eccentric nails, consequently correspond two screws, the position of two screws is: when two door leafs 6 expand and seal the door, the screw has been seted up respectively to the below of the draw-in groove 8 of two door leaf 6 overlap portions, and the body 1 spiro union of two eccentric nails is in two screws, and the center of the body 1 of same eccentric nail and guide post 22 all is in the below of the central line of same draw-in groove 8 this moment.

Next, the top of the door leaf 6 is slidably connected with the upper track through the upper wheel, at this time, the lower wheel 7 is in contact with the ground, meanwhile, the clamping groove 8 of the door leaf 6 is sleeved on the guide wheel 31, if the clamping groove 8 cannot be sleeved on the guide wheel 31 due to the deviation of the previous screw hole positioning, at this time, the opening clamp is clamped on the eccentric table 21, the opening clamp is rotated to rotate the guide post 22 and the guide wheel 31 to the position right below the central line of the clamping groove 8 of the door leaf 6, so that the clamping groove 8 of the door leaf 6 can be sleeved on the guide wheel 31 below the clamping groove 8, it should be noted that the guide wheel 31 at this time is located below the two buffering protrusions 9 of the corresponding clamping groove 8, and accordingly, the biased nail is guided at the lower part of the door leaf 6 and can be hidden below the door leaf 6, the lower track does not need to be used, and the ground is convenient to clean.

In addition, the door 6 can be pushed and pulled along the length direction of the upper rail, if the door 6 jumps up and down, the buffering protrusion 9 of the clamping groove 8 of the door 6 abuts against the top of the guide wheel 31 in the descending process, and at the moment, the buffering piece 32 is pressed to buffer the door 6 and prevent the descending impact of the door 6.

EXAMPLE III

In addition to the first and second embodiments, as for the rotation of the guiding column 22 around the body 1, another embodiment may be to rotatably mount the eccentric table 21 on the body 1, that is, when the position of the guiding column 22 needs to be changed, the position of the guiding column 22 is changed by rotating the eccentric table 21, and the body 1 does not need to be rotated, so as to prevent the looseness between the body 1 and the fixed object.

Specifically, the top of body 1 is provided with fastening screw and spacing arch, and this spacing arch is located fastening screw's below, sets up on the eccentric platform 21 to have the connecting hole, and this connecting hole cup joints on body 1, and finally eccentric platform 21 is located between lower arch and the fastening screw, fixes eccentric platform 21 on body 1 through fastening nut spiro union in fastening screw.

If the eccentric table 21 needs to be rotated to change the relative position of the guide post 22 and the body 1, the fastening nut can be unscrewed, then the eccentric table 21 is rotated, and after the guide post 22 reaches a designated position, the fastening nut is screwed.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
