This utility model reduces the probability of the refill extending out of the pen barrel when the pressure rod is pressed by external force during storage by placing the pressure rod inside the pen barrel and the pull tongue fixedly connected to the pressure rod on the vertical side of the pen barrel.

Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to a pull-type telescopic pen. Background Technology

[0002] Most commercially available writing pens currently use a top-press telescopic locking mechanism, which involves a protruding button at the top of the pen barrel. Users press this button downwards to extend or retract the pen tip. While this structure is simple and inexpensive, long-term practical use has revealed the following drawbacks:

[0003] The top button protrudes from the end of the pen barrel. When the pen is placed in a pocket, pencil case, or backpack compartment, it is easily subjected to external pressure or impact, causing the button to be accidentally triggered and the pen tip to suddenly extend. The extended pen tip can not only leave ink stains on clothing but may also puncture the fabric, causing financial losses and safety hazards to the user. Utility Model Content

[0004] The purpose of this utility model is to provide a pull-type telescopic pen. This telescopic pen has a pressure rod set inside the pen barrel and a pull tongue fixedly connected to the pressure rod set on the vertical side of the pen barrel. The pressure rod is moved by the pull tongue, thereby reducing the probability that the pen tip will stick out of the pen barrel when the pressure rod is pressed by external force during storage.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A pull-type telescopic pen includes a pen barrel and a pen refill. The pen refill extends out of and retracts from the pen barrel via a telescopic locking mechanism. The telescopic locking mechanism includes a pressure rod and a locking element. The pressure rod pushes the locking element downward to slide on a track inside the pen barrel. The pressure rod is located inside the pen barrel, and a pull tongue is fixed on the pressure rod. The pull tongue extends out to the outside of the pen barrel and is located on the vertical side of the pen barrel.

[0007] In the above technical solution, preferably, the upper end of the pen barrel is provided with a decorative part, the decorative part is in the shape of an animal head, and the tongue is adapted to the tongue of the decorative part.

[0008] In the above technical solution, preferably, the decorative part includes a front half and a rear half, the upper end of the pen barrel is provided with two symmetrical insertion holes, the rear half is provided with insertion rods that are respectively adapted to be inserted into the two insertion holes, and the front half is provided with slots that are adapted to be inserted into the two insertion rods.

[0009] In the above technical solution, preferably, the pull tab is made of an elastic material.

[0010] In the above technical solution, preferably, a pressing member is detachably inserted and fixed on the pressing rod, and a sleeve rod with a vertical cross section in the shape of a T is provided at the top of the pressing member. An elastic collar is provided at the top of the pull tongue, and the collar is adapted to be installed on the sleeve rod.

[0011] In the above technical solution, preferably, the pen barrel includes an upper pen barrel and a lower pen barrel, which are fixedly connected by a threaded structure.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This invention uses a downward-pulling latch to move a pressure rod downwards. The pressure rod presses down on the locking component and the pen refill. Simultaneously, a spring fitted onto the pen refill causes the locking component to slide up and down and rotate on a track inside the pen barrel. This telescopic locking mechanism drives the pen refill to extend and retract from the pen barrel. Because the pressure rod is located inside the pen barrel and the latch is located on the side of the pen refill, when the pen is placed in a pocket, pencil case, or backpack compartment, the probability of the pressure rod being pressed down and causing the pen refill to extend from the pen barrel due to external pressure or impact is reduced. This reduces the risk of pen tip staining clothing or puncturing fabric, minimizing economic losses and safety hazards for the user. Attached Figure Description

[0018] The components include: pen barrel 1, insertion hole 11, upper pen barrel 12, lower pen barrel 13, magnetic ring 14, pen core 2, pressure rod 3, pressing part 31, sleeve rod 32, locking part 4, track 5, pull tongue 6, collar 61, magnetic block 62, spring 7, decorative part 8, front half 81, rear half 82, and insertion rod 83. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figures 1-4This embodiment provides a pull-type telescopic pen, including a pen barrel 1 and a pen core 2. The pen core 2 extends out of and retracts from the pen barrel 1 through a telescopic locking mechanism. The telescopic locking mechanism includes a pressure rod 3 and a locking member 4. The pressure rod 3 pushes the locking member 4 downward to slide on a track 5 inside the pen barrel 1. The pressure rod 3 is located inside the pen barrel 1, and a pull tongue 6 is fixed on the pressure rod 3. The pull tongue 6 extends to the outside of the pen barrel 1 and is located on the vertical side of the pen barrel 1.

[0021] This invention uses a downward-pulling latch 6 to drive a downward-moving lever 3, which presses down on the locking member 4 and the pen refill 2. Simultaneously, a spring 7 fitted onto the pen refill 2 causes the locking member 4 to slide and rotate on a track 5 inside the pen barrel 1. This telescopic locking mechanism drives the pen refill 2 to extend and retract from the pen barrel 1. Because the lever 3 is located inside the pen barrel 1 and the latch 6 is located on the vertical side of the pen refill 2, when the pen is placed in a pocket, pencil case, or backpack compartment, the probability of the lever 3 being pressed down and causing the pen refill 2 to extend from the pen barrel 1 due to external pressure or impact is reduced. This reduces the risk of pen tip staining clothing and puncturing fabric, minimizing economic losses and safety hazards for the user.

[0022] See Figure 1 The upper end of the pen barrel 1 is provided with a decorative piece 8, which is in the shape of an animal head, and the tongue 6 is adapted to serve as the tongue of the decorative piece 8.

[0023] The aesthetic appeal of this utility model is enhanced by setting an animal head-shaped decorative piece 8 at the upper end of the pen barrel 1. At the same time, the pull tongue 6 is incorporated as a component of the decorative piece 8, which avoids disrupting the integrity of the decorative piece 8 when the pull tongue 6 is located on one side of the decorative piece 8, thereby improving the decorative effect. Furthermore, pulling the tongue-shaped pull tongue 6 can enhance the fun of using this utility model, thus improving the user experience.

[0024] See Figure 3 The decorative component 8 includes a front half 81 and a rear half 82. The upper end of the pen barrel 1 is symmetrically provided with two insertion holes 11. The rear half 82 is provided with insertion rods 83 that are respectively adapted to be inserted into the two insertion holes 11. The front half 81 is provided with slots that are adapted to be inserted into the two insertion rods 83 (slots are not shown in the figure).

[0025] By dividing the decorative part 8 into a front half 81 and a rear half 82, and by using the interlocking of the insert rod 83, the insertion hole 11 and the slot, the decorative part 8 is installed and fixed on the pen barrel 1. This makes it easier to manufacture the decorative part 8 and the pen barrel 1 separately and then assemble them, which is convenient for industrial mass production. At the same time, if there are quality problems with the front half 81, the rear half 82 or the pen barrel 1, it is easy to replace the problematic parts instead of scrapping the whole thing, which can reduce production costs.

[0026] The pull tab 6 is made of elastic material.

[0027] The pull tab 6 can be made of elastic and soft materials such as silicone or rubber, which can increase the realism of the pull tab 6 as a decorative part 8, improve the decorative effect and the feel of holding it. When the pull tab 6 is squeezed by external force, it can undergo elastic deformation, reducing the probability of damage to the pull tab 6. At the same time, when this utility model is placed in the pocket, pencil case or backpack compartment, when the pull tab 6 is pushed by external force, it will deform on its own first and then act on the pressure rod 3, thus reducing the risk of the pressure rod 3 moving and causing the pen refill 2 to extend.

[0028] See Figure 3 The back of the pull tab 6 and the pen barrel 1 are respectively provided with magnetic blocks 62 and magnetic rings 14 that can be magnetically attracted. Both the magnetic blocks 62 and magnetic rings 14 are made of soft magnetic strips, which allows the pull tab 6 to adhere to the pen barrel 1 under the action of the magnetic blocks 62 and magnetic rings 14. This reduces the risk of damage caused by the pull tab 6 being pulled or squeezed by external force when it is tilted up during storage, or the risk of the pen core 2 being accidentally extended from the pen barrel 1. In addition, the magnetic properties of the soft magnetic strips are relatively weak, making it easy for users to separate the pull tab 6 from the pen barrel 1 and pull the pull tab 6 for normal use.

[0029] See Figure 2 , Figure 3 The pressure rod 3 is detachably plugged and fixed with a pressing member 31. The top of the pressing member 31 is provided with a sleeve rod 32 with a vertical cross section in the shape of T. The top of the pull tongue 6 is provided with an elastic collar 61, which is adapted to be installed on the sleeve rod 32.

[0030] The pull tongue 6 and the collar 61 can be integrally formed and then elastically fitted onto the sleeve rod 32 by the collar 61, which makes it easy for the pull tongue 6, the pressure rod 3 and the pressing part 31 to be manufactured separately and then assembled, which is convenient for mass production.

[0031] See Figure 3 , Figure 4 The pen barrel 1 includes an upper pen barrel 12 and a lower pen barrel 13, which are fixedly connected by a threaded structure.

[0032] The upper pen barrel 12 and the lower pen barrel 13 can be separated by a threaded structure, which facilitates the assembly operation in the production process and the replacement of the pen refill 2 in the use process.

[0033] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
