Detailed Description

As shown in fig. 1 to 3, the fence fastener comprises connecting pieces 1 and interlocking pieces 2, the connecting pieces 1 are connected and limited through the interlocking pieces 2, limiting parts 3 are arranged on the connecting pieces 1, the connecting pieces 1 are sleeved with the adjacent limiting parts 3 through the interlocking pieces 2 to limit separation, and the interlocking pieces 2 and the limiting parts 3 are engaged with each other through tooth profiles to limit rotation of the connecting pieces 1 around the limiting parts 3. In the embodiment, the connection direction of the limiting part 3 relative to the connecting piece 1 is vertical, and the interlocking piece 2 is adopted to limit the direct back-to-back separation of the limiting part and the connecting piece. The toothed engagement here refers to a toothed engagement based on a bell and spigot construction, since one is relatively stationary and the other is restricted from relative rotation by the engagement. Namely, the included angle of one connecting piece 1 relative to the other connecting piece 1 can not be adjusted, and the use range of the fence can be locked in practical use.

The interlocking piece 2 comprises a shell 4, a movable seat 5 and a bottom cover 6, an elastic piece is arranged between the movable seat 5 and the bottom cover 6, the movable seat 5 and the bottom cover 6 have a separation trend through the elastic piece, and the movable seat 5 and the bottom cover 6 are separated through buckling limitation. The movable seat 5 is movably arranged in the cavity of the shell 4, and the bottom cover 6 limits the movable seat 5 to be separated from the shell 4. The movable seat 5 has a tendency to disengage from the bottom cover 6 by means of elastic means, but can be snap-fitted by means of external pressure.

The movable seat 5 is arranged in the shell 4, the shell 4 is in limit fit with the bottom cover 6, the movable seat 5 is provided with a meshing part 7, and the meshing part 7 moves through the movable seat 5 and is in limit fit with the limit part 3. Be equipped with external tooth 8 on the 7 end outer walls of meshing portion, be equipped with jack 9 on the

spacing portion

3, 9 hole bottoms of jack department are equipped with the internal tooth, it is spacing to insert jack 9 meshing through meshing portion 7 between external tooth 8 and the internal tooth, be equipped with the trompil 10 that supplies meshing portion 7 to stretch out on the shell 4. The fit between the limiting part 3 and the meshing part 7 is similar to a threaded fit, and the difference is that a toothed structure is adopted to realize sleeve meshing or meshing limiting relative to axial movement.

It should be noted that, after the movable seat 5 is separated from the bottom cover 6 as much as possible, the engaging portion 7 is engaged with the limiting portion 3 to limit the rotation of the connecting element 1, otherwise, the movable seat 5 is fastened and fixed with the bottom cover 6, and the engaging portion 7 is separated from the limiting portion 3 to enable the connecting element 1 to be angularly adjusted.

Be equipped with screens 11 on the sliding seat 5, be equipped with buckling part 12 and erection column 13 on the bottom 6, the elastic component is for cup jointing the spring on erection column 13, the lock joint is spacing between screens 11 and the buckling part 12, and recovers to exert pressure through the elastic component elasticity between screens 11 and the buckling part 12 and warp and break away from mutually. It is noted that the engagement between the locking portion 12 and the detent 11 may be excessive, i.e. the locking portion 12 and the detent 11 are elastically locked by normal pressing, and then the locking portion 12 is continuously pressed to continue the extending and depth movement. The elastic restoring force of the elastic element makes the elastic element unable to maintain the buckling state during the return stroke, so as to realize the locking and unlocking of the same-direction pressing, but the embodiment is only explained here, and the limitation is not the only limitation. In this embodiment, the elastic member is sleeved on the mounting post 13, and in a specific implementation, the elastic member may also be sleeved in a hole of the mounting post 13, which is not described herein.

The outer wall of the limiting portion 3 is provided with a first clamping block 14, the limiting portion 3 is provided with a plurality of cutting grooves 15 at the outer edge of the orifice of the jack 9, the limiting portion 3 is inserted from one end of the opening 10, and the first clamping block 14 is elastically clamped with the orifice of the other end of the opening 10. The design of the cutting groove 15 is beneficial to outward expansion and elastic deformation of the end part of the limiting part 3, so that the first clamping block 14 can be firmly clamped and limited.

The side wall of the shell 4 is provided with a slot 16, the side wall of the bottom cover 6 is provided with a second clamping block 17, and the bottom cover 6 and the slot 16 are elastically clamped with the elastic element through the second clamping block 17. Due to the arrangement and the elastic action of the elastic piece, the bottom cover 6 and the movable seat 5 have a separation tendency, and the bottom cover 6 is always positioned at one end of the shell 4 and keeps relatively unchanged. The size width of the slot 16 is larger than that of the second clamping block 17, so that space is provided for possible movement.

Be equipped with the concave surface groove 18 of fretwork on the lateral wall of sliding seat 5, be equipped with the outer groove 19 that expands that corresponds concave surface groove 18 position on the shell 4 lateral wall, sliding seat 5 presses groove face lock joint and declutch through stretching into outer groove 19 and concave surface groove 18 that expand in proper order. The hand of the human body can directly extend into the groove wall or the groove surface of the concave groove 18 to press, so that the buckling unlocking and the limiting locking are realized conveniently.
