Abstract

The utility model relates to an air pipe safety fastener of a pneumatic baling machine, which is a connecting piece of an air pipe of a pneumatic baling machine, particularly a fastening piece of a connecting pipe of a pipe joint of an air pipe. The utility model provides a safety fastener of the pipe joints of an air pipe of a pneumatic baling machine which can solve the technical problem of avoiding the machine fault caused by the desquamation of a connecting flexible pipe. The utility model has the technical scheme that a toughness metal sheet-shaped body is adopted. The utility model is characterized in that the middle part of the sheet-shaped body is in a circular ring shape, and both sides of the circular ring are respectively provided with a long strip-shaped wing sheet. The utility model is a safety fastener used for the pipe joints of a connecting flexible pipe of an air pipe of a pneumatic baling machine.

Description

Pneumatic compress tracheae security insurance button

Technical field:

The utility model relates to the attaching parts of pneumatic compress tracheae, especially the fasteners of tracheae adaptor union connection pipe.

Background technology

Pneumatic compress tracheae adopts adaptor union to connect, and an end of adaptor union has screw thread, and there is convex shoulder at the middle part, the other end has one section bamboo shoot nodular ozzle, usually after the ozzle of adaptor union inserts flexible pipe, adopt clamping band in the outside clamping of the flexible pipe of ozzle and tube socket, in case flexible pipe comes off.But, dash the phenomenon of taking off flexible pipe owing to when air pressure is higher, still have, when taking place, this phenomenon often shifts flexible pipe onto adaptor union ozzle external diameter less end together with clamping band, make clamping band lose clamping action, will cause fault for the normal operation of compress by pressure air towards ozzle with rear hose from adaptor union.

The utility model content

The utility model technical issues that need to address provide a kind of security insurance button of pneumatic compress tracheae adaptor union, the breakdown of machinery that causes to avoid connection hose to come off.

The technical solution of the utility model adopts the ductile metal plates, it is characterized in that the middle part of plates becomes the circle shape, and the circle both sides have a strip fin respectively.

Because the utility model is enclosed within circle the root of adaptor union screw thread one end in use, after ozzle inserts flexible pipe, with fin along being adjacent to the bending of flexible pipe pipe shaft, with clamping band flexible pipe is together clamped together with fin then, at last with the fin afterbody to the clamping band bending, thereby play the pulling clamping band, stop clamping band towards the terminal effect of sliding of ozzle, in addition, fin is adjacent to flexible pipe, when flexible pipe is stressed air blast generation tendency toward sliding, just has friction drag between fin and the flexible pipe and stops flexible pipe to slide, therefore the utility model can avoid pneumatic compress tracheae connection hose to come off, and plays the effect of the security insurance button of adaptor union.

Description of drawings

What accompanying drawing was represented is expansion scheme drawing of the present utility model.

The specific embodiment

Implement best way of the present utility model below in conjunction with description of drawings:

The utility model adopts the ductile metal plates, the circle shape is made at the middle part of plates, the internal diameter of circle 1 cooperates with the thread end external diameter of adaptor union, so that it is enclosed within adaptor union thread end root, the external diameter of circle 1 external diameter and flexible pipe is basic identical, when easy to use fin 2 is adjacent to along flexible pipe, circle 1 both sides are fins 2 of two symmetries, the length of monolateral fin is identical with ozzle length or slightly longer than ozzle, can cut out for unnecessary length during use, the width of fin 2 is slightly less than the external diameter of ozzle.

Its circle internal diameter of tracheae security insurance button of the tracheae adaptor union adapted of existing pneumatic compress is made Φ 21mm; External diameter can be bigger smaller with the hose outside diameter difference, general hose outside diameter Φ 28mm, and the circle external diameter is slightly larger than or is slightly less than 28mm and also allows for using; General monolateral fin length 55mm can satisfy the needs of installation, and the wide 10mm of being not more than of fin is advisable, for example 8mm or 9mm, 10mm.

Claims

1, pneumatic compress tracheae security insurance button adopts the ductile metal plates, it is characterized in that the middle part of plates becomes the circle shape, and the circle both sides have a strip fin respectively.

2, pneumatic compress tracheae security insurance button according to claim 1 is characterized in that the circle internal diameter makes Φ 21mm, circle external diameter Φ 28mm, monolateral fin length 55mm, the wide 10mm of fin.
