Description

One-hand operation of the nozzle and its working method

(1) Technical field:

The invention relates to the field of batch nozzles, in particular to a one-hand operation nozzle and a working method thereof.

(2) Background technology:

The rear pull type mouthpieces that are on sale in the market generally adopt a method of pulling the front mouth of the mouth of the hand with one hand and taking out the batch of the mouth with one hand. Especially when the nozzle is mounted on an electric or pneumatic tool, it is difficult to smoothly attach or remove the batch of the other hand while holding the electric or pneumatic or hand tool in one hand.

(3) Invention content:

The object of the present invention is to provide a nozzle that can smoothly complete the loading or unloading operation of the batch nozzle and a working method thereof. When the batch nozzle is installed, the batch nozzle can be inserted into the nozzle with one hand, and the batch nozzle After inserting the bottom, the nozzle will automatically lock the batch nozzle and cannot be pulled out. When the front sleeve of the cable is pulled with one hand, the batch nozzle automatically pops out from the inside of the nozzle, and the front sleeve is released, and the batch nozzle can be freely pulled out. It is scientific in design, simple in structure and convenient to use, and can overcome the technical deficiencies of the existing nozzle.

The technical solution of the present invention is a one-hand operation of the nozzle, which is characterized in that it comprises a post, a top block, a spring, a jacket, a rivet ring, a retaining ring, a jacket spring, a limiting member and a steel ball a, and the inside of the post is from the rear There are a spring movable hole and a batch nozzle connecting hole in the front, and a spring and a top block are assembled from the back to the front in the spring movable hole, the front end of the spring is closely attached to the rear end of the top block, and the outer wall of the connecting rod is assembled with the steel ball a, the diameter of the steel ball a is larger than the thickness of the outer wall of the post, the outer diameter of the front end of the top block is smaller than the outer diameter of the rear end of the top block, and the inner diameter of the spring movable hole at the front end of the top block is smaller than the maximum outer diameter of the top block and The front end of the post is fitted with a sleeve and is slidably engaged with the outer sleeve, and a jacket spring and a limiting member are disposed between the outer sleeve and the post. The rear end of the outer sleeve spring is provided with a retaining ring. The inner side of the outer sleeve is provided with a notch and a limiting member, and the rear end of the outer sleeve is fixedly connected with a riveting ring.

The longitudinal section of the top block is trapezoidal or stepped.

The top block is an integral structure or a split structure, and the split structure is a fixed connection sleeve and a cylinder.

The above-mentioned cylinder is magnetic steel.

The retaining ring structure includes a C-shaped retaining spring and a washer, and the C-shaped retaining spring is assembled on the post In the groove, the gasket is fitted in front of the C-shaped circlip.

The rear end of the outer casing spring abuts against the gasket, and the front end of the outer casing spring abuts against the outer casing.

The steel ball a is assembled in a bore in the middle of the post.

The above-mentioned limiting member is a half-month card or a steel ball, and the half-month card is assembled on the post by a milling groove, and the steel ball b is assembled on the post through a circular hole.

The working method of the above-mentioned one-hand operation of the nozzle is characterized in that the specific steps are as follows:

(1) Non-working state: the top block is in the pop-up state and is blocked at the foremost end of the spring movable hole. The steel ball a is blocked by the rear part of the top block, and the riveted ring is blocked, and the outer sleeve cannot be rebounded. The position of the inside of the jacket corresponds to the position of the gap, and the batch nozzle can naturally pass through the limiting member and is pushed into the nozzle;

(2) Installation of the batch nozzle: During the process of pushing the batch nozzle into the nozzle connection hole of the nozzle, the batch nozzle pushes the top block inward, and the steel ball a is located at the front part of the top block. Due to the tension of the outer casing spring, the rivet ring exists. Pushing pressure, the steel ball a is pushed by the riveting ring to the inner side of the post, the outer casing loses the resistance and rebounds forward, the notch is removed from the corresponding position of the limiting piece, and the limiting piece is pushed by the outer sleeve to the inner side of the connecting rod, when the batch of the nozzle is hit Or when the position of the groove reaches the position of the limit member, the limit member is pressed into the spot or the groove at the pressure of the jacket to lock the batch nozzle, and the batch nozzle cannot be pulled out at this time;

(3) Remove the batch of nozzles: pull the jacket backwards with one hand. When the jacket moves to the position of the notch and the limiter, the limiter loses pressure, and the batch nozzle moves forward under the tension of the spring. When the outer side of the post moves, the batch nozzle is ejected. At the same time, as the top block moves forward, the steel ball a is pushed out by the rear part of the top block to move to the outside of the post, blocking the riveting ring, and the riveting ring is blocked by the steel ball a after the outer casing is loosened. Can't bounce back, the limiter will always be in a slack state, and the batch can be pulled out with one hand.

The advantages and positive effects of the invention are: to make up for the structural defects of the conventional nozzle in this respect, and to successfully complete the installation and disassembly of the punching or grooving batch nozzle in one hand, in the use of electric or pneumatic or manual tools, the connection After the nozzle, the convenience is demonstrated in the installation or removal of the batch nozzle.
