Description

A kind of push type binding post

Technical field

The utility model relates to a kind of binding post, particularly a kind of push type binding post.

Background technology

Since half a century, in some occasion, particularly in the Experiments of Electricity of middle school, all used screw terminal to connect lead, supporting with it lead must weld lug plate.

The result of use of screw terminal is very poor, the fault that very easily produce loose contact, lug plate comes off and vacation connects.In lecture experiment and student experimenting, above-mentioned fault takes place often, and screw terminal is as easy as rolling off a log scraps, and causes temporal significant wastage to teaching.

Granted publication number is CN2414519Y, Granted publication day is that the Chinese utility model patent in January 10 calendar year 2001 discloses a kind of binding post, and it is by forming by cap, stage clip, guide pillar and spacer pin, by a hole is respectively arranged on cap and the guide pillar, guide pillar inserts to be pressed in the cap, and by spacer pin with link to each other by cap; This spacer pin embeds in the guide groove of pressing in the cap, and can upper and lowerly within it move, and stage clip is contained in the guide pillar top.

Granted publication number is CN2687860Y, Granted publication day is that the Chinese utility model patent on March 23rd, 2005 discloses a kind of press-type binding post, by urceolus, inner prop, lock shaft and spring are formed, mounting spring and inner prop in the cylindrical shape urceolus, the inner at inner prop has chute, the outer end is a screw rod, on the openend of chute, backing pin is arranged, inner prop is fixed in the urceolus by the lock shaft that inserts in the chute, two urceolus through wires holes that symmetry is arranged on outer tube wall, the inner prop through wires hole that crosses inner prop is arranged on inner prop, and the axis of inner prop through wires hole and urceolus through wires hole is on same horizontal plane.

These two kinds of binding post common characteristic are will press in use by cap (urceolus), make by the hole on the cap (urceolus) (urceolus through wires hole), with hole (inner prop through wires hole) on the guide pillar (inner prop) to good, just can inject lead.Because the restriction of the size of guide pillar (inner prop), cause the hole (urceolus through wires hole) on the guide pillar (inner prop) can not be very big, so these two kinds of binding posts be not very convenient injecting aspect the lead.

In addition, these two kinds of binding posts in order to realize its function, have all designed spacing structure.The position limiting structure of these two kinds of binding posts is complicated, causes the very inconvenience of assembling of binding post.

In addition, lead is had the hole (inner prop through wires hole) by on cap (urceolus) and the guide pillar (inner prop) of relative motion trend to clamp, and causes the damage of lead also very big like this.

The utility model content

The purpose of this utility model is to propose a kind of push type binding post, and described push type binding post need not perforate on inner prop, does not also have complicated position limiting structure, to solve the problems referred to above that present push type binding post exists.

A kind of push type binding post comprises urceolus, inner prop, elastic component, and described urceolus comprises top board and side plate, and described urceolus entangles described inner prop, offers a socket on the side plate of described urceolus; It is characterized in that, also comprise:

One block, described block are arranged on the described inner prop;

One slide block, described slide block set are positioned under the described block on described inner prop; Described slide block is fixedlyed connected with the side plate of described urceolus again, is positioned under the described socket;

Described elastic component is arranged between the top board of described block and described urceolus or under the described slide block.

Operation principle of the present utility model is as follows: when not having external force, because the effect of elastic component, slide block and block are also tight.Press urceolus with hand, elastic component is compressed, and urceolus moves downward and slide block moves down along inner prop thereupon; At this moment from socket lead will be injected, and loose one's grip, elastic component recovers deformation, and urceolus moves upward and slide block moves up along inner prop thereupon, and slide block and block are also tight, and lead is clamped.

Push type binding post of the present utility model, simple in structure, be easy to make.Need not alignment guide post hole, easy-to-connect when injecting lead.Lead is clamped by block and slide block that upper-lower position concerns, to doing little harm of lead.

Push type binding post of the present utility model also comprises the inner prop insulation shell, and described inner prop insulation shell and described inner prop are integrative-structure; Described urceolus entangles the top of described inner prop insulation shell.Prevented the exposed of inner prop like this.Further, described elastic component is arranged under the described slide block, the described slide block of termination on the described elastic component, the described inner prop insulation shell of following termination.

Push type binding post of the present utility model, described block lower surface is provided with projection or groove, and the upper surface of described slide block is provided with groove or projection.Skid off because skid in the time of can preventing lead by block and slide block clamping like this.

Novel can greatly raising of this use is wired as power, particularly can improve classroom efficiency when being applied to student's Experiments of Electricity, offers convenience to teaching.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of embodiment 1.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

Embodiment 1

Referring to Fig. 1 and Fig. 3.A kind of push type binding post comprises urceolus 1, inner prop 2, slide block 3, elastic component 4, block 5, insulation shell 6.

Urceolus 1 comprises top board 11 and side plate 12, offers a socket 10 on the side plate 12 of urceolus 1.Urceolus 1 entangles inner prop 2.Urceolus 1 is plastics.

Block 5 is arranged on inner prop 2 tops, is integrative-structure with inner prop 2.Block 2 and inner prop 2 are metals.

Slide block 3 is enclosed within on the inner prop 2, is positioned at block 5 times; Slide block 3 is cast in the side plate 12 of urceolus 1 again, and slide block 3 is positioned at socket 10 times.Slide block 3 is metals.

Block 5 lower surfaces are provided with groove, and the upper surface of slide block 3 is provided with projection.

Spring 4 is arranged between the top board 11 of block 5 and urceolus 1, on connect the lower surface of top board 11, connect the upper surface of block 5 down.

Inner prop insulation shell 6 and inner prop 2 structure that pours into an integrated entity; Urceolus 1 entangles the top of inner prop insulation shell 6.Prevented the exposed of inner prop 2 like this.

When not having external force, because the effect of spring 4, slide block 3 and block 5 are also tight.Press urceolus 1 with hand, spring 4 is compressed, and urceolus 1 moves downward and slide block 3 moves down along inner prop 2 thereupon.Just formed between block 5 and slide block 3 so at interval, this is just in time corresponding with socket 10 at interval.At this moment from socket 10 lead will be injected, and loose one's grip, spring 4 recovers deformation, and urceolus 1 moves upward and slide block 3 moves up along inner prop 2 thereupon, and slide block 3 and block 5 are also tight, and lead is clamped.In the time of lead will being taken out, can extract lead as long as urceolus 1 is pressed with hand.

Inner prop 2 outer surfaces have screw thread, when specifically installing, also need the pad (not shown), nut 7.These are prior aries well known to those skilled in the art, here repeat no more.

Embodiment 2

Referring to Fig. 2.The difference of present embodiment and embodiment 1 is that spring 4 is arranged between slide block 3 and the inner prop insulation shell 6, and spring 4 is enclosed within on the inner prop 2.Connect slide block 3 lower surfaces on the spring 4, connect inner prop insulation shell 6 upper surfaces down.
