Abstract

The utility model discloses a novel positioning spring pin, which consists of a spring, a casing, an expansion pin, a pin roll and a handle, wherein the spring is sleeved on the pin roll; a stopping boss is arranged on the pin roll; the pin roll together with the spring is pressed into the casing; an inclined plane is arranged at one end of the casing; another stopping boss is arranged in the casing; one end of the pin roll is exposed out of the inclined plane end of the casing; and the handle is arranged at the end part of the pin roll by the expansion pin. When the novel positioning spring pin is required to be positioned, the handle is positioned at the lower part of the inclined plane of the casing, and the spring is positioned in a slack state; and when the novel positioning spring pin is required to be extracted, the bottom of the handle is upwards rotated to the top along the inclined plane of the casing, the spring is compressed to the utmost extent and the pin roll is extracted out so as to realize the adjustment to a moving device. By means of a spring force, the novel positioning spring pin has the advantages of certain self-restoring function, economy in use, simpleness and convenience in operation and high reliability.

Description

A kind of novel positioning spring pin

Technical field:

The utility model relates to engineering machinery field, relates in particular to a kind of novel positioning spring pin,

Background technique:

All there are some heads in the engineering goods mostly, requiring certain controllability on the one hand, requiring the location reliable on the other hand.At present, traditional locating stud form is varied, but is broadly divided into two classes, and a class is a complex structure, handles not aspect; Another kind of is that structure is too simple, and as traditional optical axis latch, reliability of positioning is too poor.A kind of novel positioning spring pin combines the advantage of many locating studs, makes it simple in structure, and is easy to operate, and the location is reliable.The proper functioning that satisfies the mechanical activity device under the different operating modes is played an important role.

Summary of the invention:

Purpose of the present invention just provides a kind of novel positioning spring pin, optimizes the structure of traditional fastening screw, increases the operability and the reliability of locating stud.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of novel positioning spring pin, form by spring, sleeve pipe, the pin that rises, bearing pin, handle.Spring housing is contained on the bearing pin, and bearing pin is provided with the retaining platform, and bearing pin is gone in the sleeve pipe together with pressure mounting of the spring, and sleeve pipe one end is the inclined-plane, also is provided with the retaining platform in the sleeve pipe, and bearing pin one end exposes the cannula bevel end, and handle is installed in the end of bearing pin with the pin that rises.Handle is in the lower of cannula bevel when need are located, and spring is in relaxed state; When need were extracted, along being threaded to the top on the cannula bevel, length of spring compressed was to greatest extent with the handle bottom, and bearing pin is pulled out, to realize the adjustment of head.

The utility model is by spring force, have certain for reset function, use economical, easy and simple to handle, the reliability height.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Among the figure: 1, spring; 2, sleeve pipe; 3, the pin that rises; 4, bearing pin; 5, handle.

Embodiment:

Embodiment, a kind of novel positioning spring pin is made up of spring 1, sleeve pipe 2, the pin 3 that rises, bearing pin 4, handle 5.Spring housing is contained on the bearing pin, and bearing pin is provided with the retaining platform, and bearing pin 4 presses fit in the sleeve pipe 2 together with spring 1, retaining platform in spring 1 and the sleeve pipe 2 is contacted and compresses, and bearing pin 4 one ends expose sleeve pipe 2 beveled end, and the handle 5 usefulness pin 3 that rises is installed in the end of bearing pin 2.Handle 5 is in the lower on sleeve pipe 2 inclined-planes when need are located, and spring 1 is in relaxed state; When need were extracted, along being threaded to the top on sleeve pipe 2 inclined-planes, spring 1 was compressed to greatest extent with handle 5 bottoms, and bearing pin 4 is pulled out, to realize the adjustment of head.When locating once more, only need stir handle 5, make it break away from the top, bearing pin 4 stretches out under the effect of spring force automatically, and handle 5 slides to the inclined-plane lower along sleeve pipe 2 inclined-planes, realizes the adjustment of head.The utility model is simple in structure, and is easy to operate, and the location is reliable.

Claims

1. novel positioning spring pin, form by spring, sleeve pipe, the pin that rises, bearing pin, handle, it is characterized in that: spring housing is contained on the bearing pin, bearing pin is provided with the retaining platform, bearing pin is gone in the sleeve pipe together with pressure mounting of the spring, sleeve pipe one end is the inclined-plane, is provided with the retaining platform in the sleeve pipe, and handle is installed in the end of bearing pin with the pin that rises.
