Referring to fig. 1-4, an embodiment of the present invention provides an anti-drop gel ink pen, including a tube body 1, a sliding tube 2 for loading and fixing a pen refill is movably disposed in the tube body 1, the upper end of the sliding tube 2 is connected with the inner wall of the tube body 1 through a spring 3, a connecting member 4 sliding through the tube body 1 is fixedly disposed on the side wall of the sliding tube 2, an elastic push piece 5 is fixedly disposed on the connecting member 4, a limiting protrusion 6 is disposed on the outer side of the tube body 1, and a groove 7 matched with the limiting protrusion 6 is disposed on the elastic push piece 5.

Specifically, the tube body 1 is used for accommodating a pen core and is convenient for a user to hold and use; the sliding tube 2 is directly fixedly connected with the pen core and positions the pen core at the central shaft position of the tube body 1; the spring 3 keeps pushing the sliding tube 2 under the condition of external force, so that the sliding tube 2 drives the pen core to go deep into the tube body 1, and the function of taking the head of the pen core into the pen tube is realized; the elastic pushing sheet 5 is arranged at the position, close to the sucker of a user, on the outer side of the pipe body 1, and the elastic pushing sheet 5 comprises a part which is not directly connected with the connecting piece 4 and can be elastically bent towards the direction far away from the pipe body 1; the limiting protrusion 6 is hemispherical, so that the elastic pushing sheet 5 can be firstly jacked up by the limiting protrusion 6, and then the groove 7 corresponds to the limiting protrusion 6. In practical use, the tube body 1 is held by hands, then a thumb is placed on the elastic pushing sheet 5, and the elastic pushing sheet 5 is pushed, so that on one hand, the elastic pushing sheet 5 drives the sliding tube 2 to move in the tube body 1 through the connecting piece 4 and extrude the spring 3, the spring 3 is stressed to generate elastic deformation compression and store elastic potential energy, meanwhile, the sliding tube 2 drives the pen core to extend out of the tube body 1, so that the head of the pen core extends out of the tube, on the other hand, the elastic pushing sheet 5 is firstly extruded by the limiting protrusion 6 and is jacked up, then the groove 7 corresponds to the limiting protrusion 6, the limiting protrusion 6 is clamped into the groove 7, so that the elastic pushing sheet 5 is secondarily fixed on the side wall of the tube body 1, and meanwhile, a user holds the elastic pushing sheet 5, so that the head of the pen core keeps extending out of the tube for normal use; in addition, this pen barrel uses the back, with the thumb raise elasticity push jack 5 gently, then spacing protruding 6 leaves recess 7, 3 elastic potential energy release of spring and promote slide pipe 2, slide pipe 2 just drives the refill and withdraws this pen barrel again on one side, drive elasticity push jack 5 through connecting piece 4 on one side and resume initial position, can avoid refill head easily to receive the collision, prevent to take off the pearl, simultaneously, need not again like traditional push type pen barrel switching gesture, the operation has been simplified, and spacing protruding 6 embedding recess 7 is with fixed elasticity push jack 5, can guarantee that refill head stretches out stably.

Compared with the prior art, the embodiment of the utility model provides a pair of anticreep pearl gel ink pen tube is through setting up slide 2, spring 3 and elasticity push jack 5, make the refill in the slide 2 of packing into, when not using, can keep the effect that promotes to deepen inside body 1 by spring 3, and then realize taking in this pen tube with the refill is automatic, and make refill head not spill, can avoid refill head easily to receive the collision, prevent the anticreep pearl, and simultaneously, elasticity push jack 5 can the person of facilitating the use when gripping this pen tube, use thumb direct operation in order to drive refill head through connecting piece 4 and slide 2 and stretch out the use, need not to look like traditional pen tube switching gesture again, the operation has been simplified, and spacing protruding 6 embedding recess 7 is with fixed elasticity push jack 5, can guarantee refill head stretch out stably.

As a preferable technical solution of this embodiment, the cartridge includes a cartridge ink tube, a cartridge metal head, and a flange connected between the cartridge ink tube and the cartridge metal head.

As the preferred technical scheme of this embodiment, the tail end of refill ink tube slides in proper order and inserts body 1 and slide 2, and fix and set up in slide 2, and is specific, and the refill passes through the tail end of refill ink tube and slide 2 fixed connection for the refill can be along with slide 2 together removal, and then realizes that the action that refill metal head stretches out or takes in this pen tube.

As a further preferred technical scheme of this embodiment, a plurality of clamping protrusions 8 are arranged on the inner circumference of the sliding tube 2, the plurality of clamping protrusions 8 press the tail end of the cartridge ink tube inwards, specifically, the end of each clamping protrusion 8 is set to be an inclined plane, so that the tail end of the cartridge ink tube can conveniently enter between the plurality of clamping protrusions 8 along the inclined plane, each clamping protrusion 8 is made of plastic or rubber and the like, the cartridge ink tube is also made of plastic materials, the diameter of a circle surrounded by the inner sides of the plurality of clamping protrusions 8 is not larger than the outer diameter of the tail end of the cartridge ink tube, and the tail end of the cartridge ink tube can be fixedly connected with the sliding tube 2 after being inserted into the plurality of clamping protrusions 8.

As the preferred technical scheme of this embodiment, the positions on the tube body 1 and the slide tube 2 and near the tail end of the pen core ink tube are both provided with the vent holes 9, and specifically, the arrangement of the vent holes 9 ensures that the pen core can smoothly drain water.

The utility model provides an in another embodiment, body 1 lateral wall is equipped with and slides logical groove 10 with connecting piece 4 assorted, and is concrete, and connecting piece 4 is in the moving direction who slides logical inslot 10 and the moving direction of slide pipe 2 in body 1 unanimous.

In another embodiment of the present invention, the upper end of the tube body 1 is connected with the tube cap 11 by a screw thread, and the pen core metal head is movably connected with the tube cap 11, specifically, when the pen tube is used, the elastic push-piece 5 drives the sliding tube 2 to move in the tube body 1 to be close to the tube cap 11, and further drives the pen core metal head to extend out of the tube cap 11 for writing use; and after this pen holder used, spring 3 promoted slide 2 and removed and keep away from pipe cap 11 in 1 internal shift of body, and then drive the refill metal head and take in the pipe cap 11 to protect the refill metal head, prevent to take place the problem of taking off the pearl because of receiving the collision.

As the preferred technical scheme of this embodiment, a movable groove 12 is formed between the upper end of the tube body 1 and the tube cap 11, and a flange at the joint of the pen core ink tube and the pen core metal head is movably arranged in the movable groove 12, specifically, the arrangement of the movable groove 12 ensures that the flange at the joint of the pen core ink tube and the pen core metal head can move in the pen tube along with the pen core, thereby preventing the pen core from being hindered from moving.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
