Description

  The present invention relates to a pay-out type seal device in which a shaft portion to be gripped is expanded and contracted by a screw type, and the stamp can be moved in and out by the expansion and contraction operation.

As a conventional seal stamping device, hold the shaft part with both hands and remove the cap for stamping, or in the case of a writing instrument with a seal stamp, an operating part that slides up and down is provided on the clip. There are things that open and close the cap.

However, the former has the inconvenience of having to use both hands to open and close the cap, and the latter has a complicated structure and high cost.

  Therefore, the present invention is intended to provide a seal device with excellent durability as a simple structure with a small number of parts, by extending and contracting the shaft portion with both hands (can be done with one hand). is there.

  An outer shaft cylinder provided with a cap that is always closed by a spring at the tip, an inner shaft cylinder that is linearly slidable rearward from the middle portion of the outer shaft cylinder, and an inner shaft that is inside the inner shaft cylinder and the outer shaft A rotating shaft cylinder that is rotatable at a fixed position inside the cylinder, a holder that is linearly slidable forward from the middle part of the outer shaft cylinder, the shaft part is positioned inside the rotating shaft cylinder, and a seal can be attached and detached. The slider is fixed to the crown provided at the rear of the shaft tube, slides inside the shaft of the holder and can be locked at the rear end of the holder, and a screw groove is provided on the surface of the rotating shaft. The screw shaft of the inner shaft tube is fitted and the rotating shaft tube can be rotated by the expansion and contraction operation of the inner shaft tube to the outer shaft tube, and the surface of the shaft portion of the holder is provided with a feed screw groove for rotation. The feeding protrusion provided at the inner tip of the shaft tube is fitted, and the rotation of the rotating shaft tube As lifting converted to Do movement, a telescopic seal apparatus freely lid opening against a seal provided on the holder front end to the pressing force of the cap.

  As an effect of the present invention, it is possible to feed the seal stamp by an expansion / contraction operation of the shaft portion of the seal stamp body, and to provide a simple structure with high durability and low cost, and to quickly perform the assembling work.

  An outer shaft cylinder 2 provided with a cap 1 that always closes the opening 12 at the front end via a pin 10 and a spring 11, and an inner shaft that is linearly slidable backward from an intermediate portion of the outer shaft cylinder 2 A guide groove 14 in the axial direction is provided inside the rear part of the outer shaft cylinder 1, and a guide protrusion 15 provided on the outer side of the base end part of the inner shaft cylinder 6 is fitted into the guide groove 14. The inner cylinder 6 moves linearly back and forth.

  Further, a rotating shaft cylinder 4 is provided which is rotatable at a fixed position inside the inner shaft cylinder 6 and inside the outer shaft cylinder 2, but the base end of the rotating shaft cylinder 4 is outside via a retaining ring 5. The shaft cylinder 2 is rotatably mounted inside.

  Next, a holder 3 is provided in which the shaft 3 ′ is slidably linearly forward from the middle portion of the outer shaft cylinder 2, and the seal 9 is detachable. A protrusion 16 provided on the outer side of the outer shaft 2 and an axial groove 17 provided on the inner side of the outer shaft cylinder 2 are fitted so as to be able to run, so that the holder 3 is linearly moved back and forth.

  Next, it fixes to the crown 8 provided in the back of the inner shaft cylinder 6 and slides inside the shaft portion 3 ′ of the holder 3, and the locking protrusions 18, 18 ′ are engaged with each other at the rear end portion of the holder 3. A slider 7 that can be stopped is provided.

  A screw groove 19 is provided on the surface of the rotating shaft cylinder 6, and the screw protrusion 20 of the inner shaft cylinder 6 is fitted and the screw protrusion 20 is threaded by the expansion / contraction operation of the inner shaft cylinder 6 to the outer shaft cylinder 2. The guide projection 15 moves along the guide groove 14 at the same time, and the rotary shaft cylinder 4 rotates.

  On the other hand, the surface of the shaft portion 3 ′ of the holder 3 is provided with a feed screw groove 21 in a direction opposite to the screw groove 19, and a feed protrusion 22 provided at the inner end of the rotary shaft cylinder 4 is fitted. The feeding protrusion 22 is moved by the rotation of the rotating shaft cylinder 4.

  In the figure, reference numeral 13 denotes an intrusion groove provided continuously at the ends of the screw grooves 19 and 21 for the corresponding protrusions 20 and 22 to enter during assembly, and also provided in the shaft portion 3 ′ of the holder 3. A flat locking groove 21 ′ is provided at the end position of the feeding screw groove 21 so that the sliding with the feeding protrusion 22 is deteriorated so that the locking groove 21 ′ and the feeding protrusion 22 are detached by rotating, Shrinkage due to front and rear pressing force when using a seal is freely made possible.

Action

  The present invention is configured as described above. In order to change from the contracted state of FIG. 1 to the extended state of FIG. 2, the screw projection 20 is threaded into the screw groove 19 by pulling backward with the crown 8 or the inner shaft cylinder 6. At the same time, the rotating shaft cylinder 4 rotates, the feeding protrusion 22 moves through the feeding screw groove 21 to feed the holder 3 forward, and the cap 1 is opened against the pressing force of the spring 11 to perform the printing operation. At this time, the holder 3 stops rotating by the protrusion 16 and the guide groove 17 and moves linearly, so that the front and rear positions of the seal 9 are not always changed, and an accurate stamping operation can be performed.

  In order to change from the extended state of FIG. 2 to the reduced state of FIG.

  When the feeding protrusion 22 is fitted in the lock groove 21 ', it is possible to prevent contraction due to the front and rear pressing force when using the seal, and a smooth printing operation can be performed.

  In combination, each part can be quickly inserted and bonded.
