Specific embodiment

The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.

As shown in Figures 1 to 8, a kind of staking pin structure described in the utility model, including nail rod 10 and lock ring 30, lock ring 30 Interior to be equipped with through-hole 36, the molding of 30 one end of lock ring is equipped with baffle 35, and the upper end of nail rod 10 is equipped with head 11, and the lower end of nail rod 10 passes through Through-hole 36 is arranged, and the outer wall on head 11 is equipped with multiple elastic force snap arm 20 that can be opened and closed, and elastic force snap arm 20 is corresponding with baffle 35 Setting is equipped with buckle structure between elastic force snap arm 20 and lock ring 30, clamping structure and positioning are equipped between nail rod 10 and lock ring 30 Structure.The above constitutes the utility model basic structure.

The utility model uses such structure setting, under the action of buckle structure, by lock ring 30 by multiple elastic force Snap arm 20 is in closed configuration, and under the action of clamping structure, lock ring 30 is clamped to 13 position of partes glabra of nail rod 10, uses When, it first drills respectively on needing fixed fixation 70 and on the wall 80 of fixed object, by the head 11 of nail rod 10 One end is through at drilling together with lock ring 30, until the baffle 35 of lock ring 30 is bonded setting with the drilling on fixation 70, this When, the lower part of nail rod 10 is enforced, when strength is greater than the clamping force of clamping structure, 10 slid inward partial distance of nail rod, Since baffle 35 is limited in bore position, elastic force snap arm 20 is separated with lock ring 30, wink under the action of screen resilience of elastic force snap arm 20 Between open, at this point, a hand withstands baffle 35, another pulls the lower part of dynamic nail rod 10, until between nail rod 10 and lock ring 30 It is positioned by location structure, clamps fixation 70 and wall 80 to realize and be realized by elastic force snap arm 20 with baffle 35, Extra 10 lower part of nail rod is finally cut into i.e. completion installment work with cutting nippers, the utility model effectively increases fastening effect, Structure is simple, is easy to produce in enormous quantities, and manufacturing price is cheap, and installation efficiency is high, does not have noise in work, will not be to object There is damage in body surface face.

In practical application, boring aperture described in the utility model is necessarily less than 35 outer diameter of baffle, and has to be larger than nail rod 10 11 outer diameter of head.

It should be noted that the utility model can be attached the material of multilayer or interlayer, it is particularly suitable for thin The fixation of plate.

More specifically, 30 other end of the lock ring molding is equipped with casing 38, and buckle structure includes being set to elastic force snap arm 20 On groove 21 and the protrusion 31 on casing 38, protrusion 31 snapped connection with groove 21.Using such structure setting, It is snapped connection by protrusion 31 with groove 21 and realizes the effect that multiple elastic force snap arm 20 are in closed configuration by lock ring 30.

More specifically, the clamping structure includes the partes glabra 13 in nail rod 10 and the card in through-hole 36 Corresponding clamp of partes glabra 13 is arranged for ring 32, snap ring 32.Using such structure setting, realizes and lock ring 30 is clamped to nail rod 10 13 position of partes glabra avoids lock ring 30 from being displaced the disengaging caused with elastic force snap arm 20.

In practical application, set in through-hole 36 described in the utility model there are four snap ring 32, and four snap rings 32 respectively between The aperture for being arranged at a certain distance, and being made of four snap rings 32 is less than the outer diameter of the partes glabra 13 of nail rod 10, when partes glabra 13 When set on four 32 positions of snap ring, partes glabra 13 struts four snap rings 32, make partes glabra 13 outer diameter and four snap rings 32 it Between form frictional force, to partes glabra 13 be clamped by snap ring 32.

More specifically, it is equipped with card slot 33 between the snap ring 32 and the inner wall of through-hole 36, is equipped with lantern ring 40 in card slot 33. It using such structure setting, is placed on snap ring 32 by lantern ring 40, effectively improves the toughness of snap ring 32, make snap ring 32 in nail rod Under 10 push and pull, it not will cause brittle failure, improve its service life.

More specifically, the top of the card slot 33 is equipped with the stop collar 34 with the limit setting of lantern ring 40.Using such Lantern ring 40 is limited in card slot 33 by structure setting by stop collar 34, prevents lantern ring 40 from deviating from.

More specifically, the location structure includes upper ring gear portion 12 in the nail rod 10 and on snap ring 32 Latch 320, the upper positioning setting corresponding with latch 320 of ring gear portion 12.Using such structure setting, nail rod 10 and lock ring 30 are realized Between positioning.

In practical application, the latch 320 on snap ring 32 described in the utility model is using the pawl slightly tilted down, upper ring gear Portion 12 is equipped with the tooth socket for match setting with latch 320, and tooth socket is using slightly upwardly inclined pawl slot, when latch 320 and Tooth socket can only be pulled out to when corresponding to, and can not inwardly be pushed, using band principle, to realize the effect for the more drawing the more tight.

More specifically, the elastic force snap arm 20 is equipped with the position limiting structure of limitation 20 opening degree of elastic force snap arm.

In practical application, set on the outer wall on head 11 described in the utility model there are four open setting elastic force snap arm 20, when original state, four elastic force snap arm 20 for opening setting and head 11 are to be vertically arranged, and elastic force snap arm 20 is using elasticity material Matter is made, and under the action of position limiting structure, can control the opening degree of elastic force snap arm 20.

More specifically, the position limiting structure includes the non-resilient limit rope between two neighboring elastic force snap arm 20 60.Using such structure setting, will be tensed between two neighboring elastic force snap arm 20 by limiting rope 60, to play limit The opening width of elastic force snap arm 20 when firmly pulling the lower part of nail rod 10 in operation, can be made in the opposite pulling force of limit rope 60 Under, so that the opening width between multiple elastic force snap arm 20 is opened up into maximum, become placed against elastic force snap arm 20 completely with wall 80.

More specifically, the lower part of the nail rod 10 is equipped with anti-slip part 14.Using such structure setting, cylinder is being pushed It can play the role of Skidproof labor-saving when staple bar 10 or pulling cylinder nail rod 10.

The technical scheme in the embodiment of the utility model is described above, but the utility model is not limited to The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model Under, many forms can be also made, these are belonged within the protection scope of the utility model.
