(54) БЫСТРОРАЗЪЕМНОЕ СОЕДИНИТЕЛЬНОЕ УСТРОЙСТВО(54) QUICK DISCHARGE CONNECTING DEVICE

Изобретение относитс к области машиностроени и может быть использовано в отрасл х промышленности дл соединени деталей, требующих частой и быстрой, сборки и разборки.The invention relates to the field of mechanical engineering and can be used in industrial sectors for connecting parts that require frequent and quick assembly, disassembly and assembly.

Известно быстроразъемное соединительное устройство, выполненное в виде пальца, состо щего из корпуса и подпружиненного толкател , устанбвленн ого в его-внутренней полости и фиксатора, выполненного в биде упругой пластины, закрепленной на конце толкател и взаимодействующей с торцовой кромкой корпуса 1.A quick-release coupling device made in the form of a finger consisting of a body and a spring-loaded pusher installed in its internal cavity and a clamp made in a bidet of an elastic plate fixed at the end of the pusher and interacting with the end edge of the body 1 is known.

Недостатком устройства вл етс необходимость в достаточно большом диаметре пальца дл размещени сос ,тавных частей, а также недостаточна надежность фиксации пальца.The drawback of the device is the need for a sufficiently large finger diameter for accommodating the coaxial, common parts, as well as insufficient reliability of fixing the finger.

Известно также быстроразъемное соединительное устройство, выполненное в виде пальца, содержащего корпус , в центральном отверстии которого размещены толкатель и упругий .пластинчатый фиксатор, закрепленный на тоЬде корпуса и взаимодействующий своими концами с кольцевой канавкой толкател и торцовой кроткой корпуса 2.It is also known to have a quick-release connecting device made in the form of a finger, comprising a housing, in the central hole of which a pusher and an elastic plate latch are mounted, fixed on the housing and interacting with the ends of the pusher and the end face of the housing 2.

Такое устройство вл етс наиболее близким к изобретению по технической сущности и достигаемому результату . :Such a device is closest to the invention in its technical essence and the achieved result. :

Недостатком его вл етс то, что дл размещени составных частей требуетс увеличение поперечного сечени пальца. Кроме того в разобранном состо нии палец не зафиксирован, The disadvantage is that the placement of the component parts requires an increase in the cross section of the finger. In addition, the finger is not locked in the disassembled state,

0 что может привести к его утере или поло1ке. 0 which can lead to its loss or loss.

Целью изобретени вл етс повышение удобств обслуживани .The aim of the invention is to improve the convenience of service.

Claims

For this, the proposed device is provided with an elastic element, freely placed together with a clamp in the housing and interacting with the said clamp, the clamp being made in the form of a washer with a finger-length opening, and the finger is made with two annular grooves with which the clamp interacts. Fig, 1 shows the device, a general view; in fig. 2 - the same, top view; FIG. 3 is a section along A-A in FIG. one; in fig. 4 shows the device; the embodiment of FIG. 5 is a section along BB in FIG. 4. The device comprises a part 1 and an eyelet 2, through the holes of which a finger 3 is missed, a retainer 4 pressed by an elastic element 5, the retainer being movably mounted in a housing 6 fixed with a cover 7 and bolts 8 to the eye. There are two annular grooves 9 on the finger, each of which engages with the washer in the extreme: finger positions. A possible embodiment of the device shown in FIG. 4 and 5, which is distinguished by the fact that a spiral compression spring is used as a resilient element for pressing the clamp. The assembly of the device is carried out by inserting a finger by the handle 10 through the eyelet 2 into the part 1 up to the stop. At the same time, at the beginning of the stroke with the bevel of the 11th finger, the retainer is retracted, deforming the elastic element, and at the end of the course the washer drops into the corresponding finger groove. The development of the device is performed by removing a finger from the handle 1 from the part 1 and the eyelets, for which one presses the locking tab 12 until it stops. Simplifying the design of the device by making the finger solid with two grooves, and the retainer in the form of a spring-loaded washer mounted on the eye, increases reliability and reduces the labor intensity of manufacturing the specified device. The presence of two fixed finger position improves device maintenance during operation. Claim 1. A quick-release coupling device comprising a housing, a finger and a latch, which is so that, in order to enhance the convenience of service, the device is provided with an elastic element freely positioned together with the fixture in it. orpus, moreover, the latch is made in the form of a washer with a hole for the finger, and the finger is made with two, annular grooves. 2. The device according to claim 1, wherein the elastic element is made in the form of a spiral compression spring. Sources of information taken into account in the examination. 1.
