Description

Technical Field

[0001] The utility model relates to the technical field of push-type pens, and more specifically to a sealable push-type pen. Background Art

[0002] A push-type fountain pen is a fountain pen that controls the tip of the pen by pressing. Compared with traditional fountain pens, push-type fountain pens are more convenient to use and provide better protection for the pen tip. In today's market, push-type fountain pens are widely popular. When the existing push-type fountain pens are in use, the pen tip is directly exposed to the outside air, and it is easy for the ink at the pen tip to dry out if it is idle for a long time. There is a lack of a suitable sealing protection mechanism. In addition, when the device is in use, the sealing protection mechanism lacks a suitable quick reset adjustment mechanism during use. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides a sealable press-type fountain pen to solve the technical problem of lack of a suitable quick-reset adjustment mechanism during the use of the sealing protection mechanism mentioned in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealable press-type fountain pen, comprising a pen neck, a lower rod and a push pull, the lower rod being installed at the bottom of the pen neck, the push pull being slidably installed inside the lower rod, a middle connection being provided between the pen neck and the lower rod, the middle connection and the lower rod being threadedly matched, the middle connection and the pen neck being detachable, a sheath mechanism being provided inside the pen neck, the sheath mechanism comprising a silicone sleeve and a sheath body, the sheath body being slidably installed inside the pen neck, the silicone sleeve being slidably installed at the front end of the sheath body, a cap being hinged at the front end of the silicone sleeve, a core mechanism being slidably provided inside the sheath body, a spring being connected between the core mechanism and the silicone sleeve.

[0005] The utility model is further configured that the lower rod is provided with a pen clip body, the pen clip body is provided with a pen clip positioning ring, and the pen clip positioning ring is installed at the bottom end of the lower rod to facilitate overall placement and clamping.

[0006] The utility model is further configured that a clamping block is provided on the inner wall of the pen item, and a plurality of the clamping blocks are provided in the circumferential direction, and a clamping groove is provided on the middle outer end surface corresponding to the plurality of the clamping blocks to realize clamping when installing the pen item.

[0007] The utility model is further configured such that the refill mechanism comprises a refill body, a core and a support rod, wherein the core is slidably mounted on the outer end of the sheath body, the refill body is mounted on the front end of the core, and the support rod is mounted on the rear end of the core for easy ejection.

[0008] Compared with the prior art, the utility model provides a sealable press-type fountain pen, which has the following beneficial effects:

[0009] 1. Through the design of the sheath mechanism, the sheath mechanism is composed of a silicone sheath and a sheath body. The silicone sheath is slidably arranged relative to the sheath body. The sheath body is installed through the silicone sheath. The cover cap hingedly arranged on the silicone sheath realizes sealing protection for the internal refill body.

[0010] 2. Through the design of the spring, the spring connection is set between the neck core and the silicone sleeve. When the core body is pushed outward, the spring elastic force pushes the sheath body, driving the sheath body to slide to the outermost side. When the core body is retracted, the spring retracts, and the neck core pushes the sheath body to slide back to its original position. BRIEF DESCRIPTION OF THE DRAWINGS
