The specific embodiment

In order further to explain, be described in detail the technical solution of the utility model below by specific embodiment.

A kind of simple and easy plastics sling of the present utility model, as Figure 1-4, comprises plastics box 1 and is inserted in the plastics pin thread 2 in plastics box 1.

Plastics pin thread 2 is equipped with Anti-extrusion device, improvements are, the bottom of the inner chamber of plastics box 1 is the shape smoothly narrowing down gradually from top to bottom, the bottom of the inner chamber of the corresponding plastics box of plastics pin thread 2 is provided with the leg 21 of two elasticity opening and closing, utilize the elastic characteristic of conventional sling plastic material self, the leg 21 of two elasticity opening and closing of plastics pin thread 2 is matched with the level and smooth gradually bottom of narrow inner chamber of plastics box 1, when two legs 21 insert gradually plastics box 1 and are the bottom of inner chamber, two legs 21 slide along the inclined-plane of the bottom of inner chamber, and according to the bottom of inner chamber shape wide at the top and narrow at the bottom flexible polymer gradually, two legs 21 are had to clamping trend, and there is a driving force upwards, with this, replace the elastomeric elements such as spring of traditional sling, realize the bottom of inner chamber and the plug of the elasticity of two legs 21, Anti-extrusion device assurance plastics pin thread 2 can not deviate from from plastics box 1, realizing the lacing hole 12 of the plastics box 1 that switch matches and 23 pairs of ropes that regulate of lacing hole of plastics pin thread 2 uses length and degree of tightness to regulate, overcoming traditional sling needs the labyrinth defect of the elastomeric elements such as spring, and integral body is plastic material, can one-shot forming, and containing metal not, be convenient to reclaim.

For the inner chamber bottom of the reinforced plastics box 1 clamping trend to two legs 21, to improve the bottom of inner chamber and the elasticity of two legs 21 plug intensity, preferably, the lower sides of the inner chamber of plastics box 1 is indent arc.

Preferably, the cross section of the inner chamber of plastics box 1 is rounded, and plastics pin thread 2 matches with plastics box 1.

Preferably, the outside of two legs 21 is provided with projection 211, corresponding two projections 211 of the sidewall of the inner chamber of plastics box 1 are provided with Anti-extrusion fixture block 11, and projection 211 and Anti-extrusion fixture block 11 have formed Anti-extrusion device, can guarantee that plastics pin thread 2 can not deviate from from plastics box 1.

Preferably, the downside of projection 211 is formed with the inclined-plane 2111 of taking advantage of a situation, or the upside of Anti-extrusion fixture block 11 is formed with the inclined-plane 111 of taking advantage of a situation, when plastics pin thread 2 inserts in plastics box 1, take advantage of a situation inclined-plane 2111 or the inclined-plane 111 of taking advantage of a situation makes projection 211 and Anti-extrusion fixture block 11 can not form insertion obstacle, plastics pin thread 2 can be taken advantage of a situation and be slipped in plastics box 1, is convenient to projection 211 and is fastened togather with Anti-extrusion fixture block 11; Further preferred embodiment is, the downside of projection 211 is formed with the inclined-plane 2111 of taking advantage of a situation, and the upside of Anti-extrusion fixture block 111 is also formed with the inclined-plane 1111 of taking advantage of a situation, better effects if simultaneously.

For the plug fit structure between specific implementation plastics box 1 and plastics pin thread 2, and guarantee the directionality of plug, preferably, two projection 211 symmetries are divided into the bottom of two legs 21, and two Anti-extrusion fixture blocks 11 are the corresponding center that is formed at the inner chamber of plastics box 1 respectively, the lacing hole 12 of plastics box 1 is formed at the top of Anti-extrusion fixture block 11, the sidewall of the inner chamber of plastics box 1 is formed with the arrangement that alternates of two two lacing holes 12 with plastics box 1, and slide rail along the vertical direction 13, corresponding two slide rails 13 in both sides of plastics pin thread 2 are formed with respectively chute 22, plastics pin thread 2 can rely on chute 22 to coordinate with the directed relative sliding of slide rail 13, realize directed plug with plastics box 1, and guarantee that projection 211 is fastened togather with Anti-extrusion fixture block 11 is corresponding, when two legs 21 be subject to plastics box 1 inner chamber effect and after resilience, can rely on projection 211 to avoid with the buckle structure of Anti-extrusion fixture block 11.

For the ease of projection 211, be stuck in the below of Anti-extrusion fixture block 11, and being convenient to people operates projection 211, preferably, plastics box 1 is formed with open-work 14 below two Anti-extrusion fixture blocks 11, specifically, this open-work 14 is corresponding with the projection 211 after buckle, this open-work 14 reserves the short space of outwards opening and be beneficial to buckle to projection 211, people also can operate by 14 pairs of projections 211 of this open-work and leg 21, as inwardly supported projection 211, projection 211 and Anti-extrusion fixture block 11 are threaded off, and then plastics pin thread 2 is split out from plastics box 1.

Preferably, the inner chamber of plastics box 1 is the shape smoothly narrowing down gradually from top to bottom, and the whole inner chamber of plastics box 1 all can carry out flexible drive effect upwards to two legs 21.

For the ease of processing and forming, and strengthen globality, preferably, leg 21 is structure as a whole with plastics pin thread 2.

Simple and easy plastics sling of the present utility model, leg and plastics pin thread are preferably integrative-structure; The concrete shape of the inner chamber bottom of plastics box also can be adjusted and design according to actual requirement, more in a broad aspect, the inner chamber of plastics box is preferably only has bottom or integral body to be the shape smoothly narrowing down gradually from top to bottom, and concrete form also can be adjusted and design according to actual requirement; The shape of open-work, size etc. can be adjusted and design according to actual requirement; The form of slide rail and chute can be adjusted and design according to actual requirement; The shape of Anti-extrusion fixture block, size and setting position etc. can be adjusted and design according to actual requirement; The upside of the downside of projection or Anti-extrusion fixture block is formed with the inclined-plane of taking advantage of a situation, also can the downside of projection and the upside of Anti-extrusion fixture block be all formed with the inclined-plane of taking advantage of a situation, concrete form can be adjusted and design according to actual requirement; The form of Anti-extrusion device also can be adjusted and design according to actual requirement; Plastics box is roughly similar with the structure of the structure of plastics pin thread and the box of existing sling and pin thread, but concrete structure can be cooperation the technical solution of the utility model and does adaptive structural adjustment.

Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable variation or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
