Abstract
The utility model relates to the metals mechanical field, in particular to a ring form arming pin with simple, practical and low cost, which comprises a pin rod and a pin ring, wherein the two ends of a spring pin ring 1 are fixed in holes 4 which are arranged on both sides of a hammer end 3 of a hammer pin rod 2, the length of the pin rod 2 is larger than the diameter of the pin ring, a pin ring 1 is located in the pin rod 2 after being buttoned, and the holes 4 of the both sides of the hammer end of the pin rod are arranged upper and down in staggered row. When in use of the ring form arming pin, the pin rod is inserted into to-be-pined object, and the spring tension of the pin ring is utilized to press the pin ring to the pin rod, thereby, the to-be-pined object is located in the pin rod which is pressed by the pin ring and is uneasy to be arbitrarily shedded, thereby, the aim of safety insurance is realized, and the ring form arming pin has the advantages of simple manufacturing and convenient to use, low cost and good safety.
Description
Technical field
The utility model belongs to the hardware machinery field.
Background technique
Arming pin in the existing machinery technical field is commonly called as latch, and no solid shape is generally decided on different occasions, inserts around once getting final product with metallic rod or crude iron screw mandrel conveniently under the interim occasion.Generally the metal pin rod is inserted and treat behind the mounting article pin rod bending two ends to be pinning, there is hidden danger in above-mentioned present situation.Pin rod easily comes off, and is very dangerous; Use inconvenient, fixing too carefully insecure, too slightly not flexible with crooked pin rod.Random too big product causes not only dangerous but also lack of standardization, so a kind of simple and practical arming pin of market in urgent need.
Summary of the invention
The purpose of this utility model provides a kind of simple, practical, annular arming pin that cost is low.
Annular arming pin of the present utility model, form by pin rod, lock ring, it is characterized in that spring lock ring (1) two ends are fixed in the hole (4) of capitate end (3) both sides of capitate pin rod (2), pin rod (2) length is positioned on the pin rod (2) after lock ring (1) is detained greater than the lock ring diameter.
Annular arming pin of the present utility model, the hole (4) of pin rod capitate end both sides are arrangements straggly up and down.
Annular arming pin of the present utility model, used pin rod can be hollow.
During the utility model production, the capitate pin rod capitate end both sides of making are straggly the fixedly hole of lock ring, and lock ring is the annular spring of both ends open, and two ends are fixed in the hole, so between lock ring and the pin rod very strong tension force is arranged.
When the utility model product uses, pin rod inserted treat in the pin object, utilize the spring tension of lock ring that lock ring is pressed to pin rod, treat so that pin earnest body is positioned at by the pin rod of lock ring compression set can not come off arbitrarily, reach the purpose of security insurance.
The utility model is made simple, and easy to use, with low cost, Security is good.
Description of drawings
Fig. 1 is the utility model product lock ring Unclosing structure schematic representation.
Fig. 2 is the utility model product lock ring compression set pin rod structural representation.
Number in the figure: 1, lock ring, 2, pin rod, 3, pin rod capitate end, 4, pin rod capitate stomidium.
Embodiment
The spring steel of getting a diameter 3mm makes diameter 50mm lock ring, both ends open.Make the capitate pin rod of a diameter 8mm again, stragglyly respectively in the capitate both sides open two holes, so promptly obtain the good arming pin of Security, can be used for the occasion of suitable size in order to the lock ring two ends are fixed.
According to the difference of use occasion, the utility model can correspondingly make this series products of different size size, and what adapt to different size sells the earnest body on a commission basis.
Claims (3)
1. an annular arming pin is made up of pin rod, lock ring, it is characterized in that spring lock ring (1) two ends are fixed in the hole (4) of capitate end (3) both sides of capitate pin rod (2), and pin rod (2) length is positioned on the pin rod (2) after lock ring (1) is detained greater than the lock ring diameter.
2. annular arming pin as claimed in claim 1, the hole (5) that it is characterized in that pin rod capitate section both sides are arrangements straggly up and down.
