Description

The present invention belongs to the technical field of stationery, and specifically relates to a cap slide pen.

Writing instruments are indispensable for people such as students and writers. Conventional writing tools are generally click-type or have a cap. In a writing instrument with a cap, the shaft body has a screw and is screwed to the pen tip to arrange the pen core on the shaft body.

A writing tool with a cap may burst at the pen tip if it is used by holding it with excessive force for a long period of time or if it falls unexpectedly during use. In this case, the pen core tends to shake, which interferes with normal writing. Also, if the cap is accidentally dropped and lost, the ink may stain other objects such as clothing and paper because there is no cap at the front end of the pen core. If a click-type writing tool suddenly falls during use and hits the floor with the rear cover (rear lid), there is a high possibility that the spring inside it will come off. In this case, writing cannot be performed normally, and even the pen case must be replaced, which is a waste. Also, while the click pen is in use, the spring inside it may be misaligned, but in this case, it does not go smoothly when clicking, and you may be able to write if you try it many times. Also, the click pen is mightier
Since the force to expose or immerse the pen core by clicking (pressing) is set to a small force, contact with the knock mechanism is inevitable when putting it in a bag, attaché case or pocket, and the pen core is exposed and the attaché It can stain the paper, lining and clothing pockets inside.

When the clip is released, the pushing and pulling means is axially second in the shaft by the elastic force of the return spring.
It slides to the state so that the stop engager comes into contact with the fixed structure and the pen core is exposed, and the clip is pushed backward again so that the stop engager comes into contact with the fixed structure by the drive of the pushing and pulling means. It is configured so that it can be detached from the state and entangled in the fixed structure so that the pen core can be immersed.
The pushing / pulling means includes a sliding cylinder and a pressing cylinder that are fixedly connected to each other, the sliding cylinder is located on the front side of the pressing cylinder, the sliding cylinder and the clip are fixed, and the sliding cylinder and the shaft body slide.

The cap slide pen is characterized in that.

In this proposal, the pen core can be slid in the axial direction by means of pushing and pulling.
Furthermore, it is possible to control whether the pen core is exposed outside the front cylinder or is immersed inside the front cylinder.
The work is easy and convenient, the separate cap can be omitted, and the pen core can be prevented from being easily exposed outside the front cylinder when the external force is small, so the pen core can be easily exposed by external pressure. It can be ensured that it will not be damaged, and that external objects will not be easily contaminated by ink.

Preferably, the pushing and pulling means includes a sliding cylinder and a pressing cylinder that are fixedly connected to each other, the sliding cylinder is located on the front side of the pressing cylinder, the sliding cylinder and the clip are fixed, and the sliding cylinder and the shaft body are connected to each other. It is slidably connected, one end of the return spring is located inside the pressing cylinder, and the other end is in contact with the rear cylinder lid, and a stop block is fixedly installed on the inner wall of the front part of the slide cylinder. A pen groove is formed between the sliding cylinder and the inner wall of the front portion, and the pen core is engaged in the pen groove. In this way, when the pen core is immersed, the clip is pushed backward, the sliding cylinder and the pressing cylinder are slid backward along the axial direction of the shaft body by the clip, and the return spring is released by the pressing cylinder. While pressing, the stop engagement element can be gradually detached from the fixed structure. When the clip is released, the elastic action of the return spring causes the pen core to slide forward in the axial direction inside the shaft by the pressing cylinder and the sliding cylinder, exposing the pen core outside the front cylinder and fixing the stopper engagement member again. The pen core that comes into contact with the structure and is exposed outside the front cylinder can be fixed.

Preferably, the distance between the inner wall of the rear portion of the working groove and the rear portion of the clip is equal to or greater than the maximum elastic displacement of the return spring and less than or equal to the distance between the pressing cylinder and the rear cylinder lid. In this way, by the time the clip is pushed backwards and approaches the inner wall at the rear of the working groove, the return spring can be made to have not only reached or already reached the maximum elastic force, so that the clip can be pushed to the maximum. Does not occur easily. In addition, the compressive force of the return spring is small (and therefore the rebounding force is small), so that the pen core cannot easily be ejected from the front cylinder. Further, since the pressing cylinder does not contact or just contacts the rear cylinder lid, in the initial state (that is, the pen core is immersed), the pressing cylinder and the rear cylinder lid are pressed by the clip with a sufficient distance. The return spring can be compressed by driving the cylinder.

Preferably, the stop engager is fixedly installed at the rear of the stop block, a sliding surface is provided on the rear side of the lower end of the stop engager, and an auxiliary positioning surface is provided on the front side of the lower end of the stop engager. A hook engaging body is formed between the hook engaging body and the auxiliary positioning surface, and the hook engaging body and the fixed structure are engaged and connected. In this way, the hook engaging body engages the fixed structure when the pen core is immersed. When the pen core is exposed outside the front cylinder, the fixed structure acts as a baffle for the hook engagement body after the position change, and the hook engagement body cannot easily slide inside the shaft, and the position of the pen core. Functions to fix.

Preferably, the fixing structure includes a fixing block fixedly installed on the inner bottom wall at the rear of the shaft body and an engaging groove provided in the fixing block, and the fixing block is located inside the sliding cylinder. The hook engaging body and the engaging groove are hook-engaged, and the main first positioning surface and the guide surface are provided on the front portion and the rear portion of the engaging groove, respectively, and the sliding surface and the guide surface come into contact with each other for auxiliary positioning. The surface and the main first positioning surface are in contact with each other, and the main second positioning surface for contacting the stopper engaging element is provided at the front portion of the fixed block. In this way, in the process of pushing the clip backward and gradually separating the stop engager from the fixed structure, the stop engager gradually moves along the guide surface, and the position of the stop engager on the guide surface is the main. Move up until it is higher than the position of the second positioning surface. When the clip is released, the elastic action of the return spring disengages the stopper from the engagement groove and moves it forward in the shaft body. After the return spring reaches its maximum force (that is, the pen core is exposed from the front cylinder), the stop engager backbuffers at a short distance by the action of inertial force.
Further, the stop engager hits the guide surface, and the stop engager and the main second positioning surface come into contact with each other.
The stop engager can be positioned.

Preferably, the surface area of the guide surface is larger than the surface area of the main second positioning surface, and the inclination of the main second positioning surface and the guide surface are equal to each other. In this way, in the process of moving the stop engager backward and separating it from the engagement groove, since there is a sufficient movable distance of the stop engagement element on the surface of the guide surface, the stop engagement element is moved. It is possible to move it to a position higher than the surface with the upper end of the main second positioning surface on the guide surface, and after the stop engaging element is detached from the engaging groove by the elastic action of the return spring, the main second positioning surface It is possible to move forward in the axial body beyond a certain surface.

Preferably, the cross-sectional length of the guide surface is greater than the maximum elastic displacement of the return spring and greater than or equal to the distance between the pressing cylinder and the rear cylinder lid. In this way, even when the return spring is pressed to the maximum force by the pressing cylinder, the stop engaging element can be prevented from being detached from the guide surface yet. Thereby, in the process of pressing the return spring by the pressing cylinder, the stop engaging element can be prevented from being easily disengaged from the engaging groove.
Preferably, the vertical distance between the rear end of the main second positioning surface and the inner wall of the axle is less than or equal to the maximum elastic displacement of the return spring and less than or equal to the distance between the pressing cylinder and the rear cylinder lid. In this way, when the return spring has already reached or has just reached its maximum force, the moving vertical distance of the stop engager on the guide surface is the rear end and shaft of the main second positioning surface. It is more than the vertical distance between the body walls. When the clip is released by this, the stop engaging element is disengaged from the engaging groove by the elastic force of the return spring, and then the pen core is exposed from the front cylinder beyond the surface having the rear end portion of the main second positioning surface. Can be done.

Preferably, the positioning protrusion is fixedly installed on the surface of the rear cylinder lid located inside the axle, and the positioning protrusion is located inside the return spring. In this way, in the process of pushing the clip backward to compress the return spring, the return spring does not easily bend and slide away from the pressing cylinder, and at the same time, when the clip is released, the return spring has its own elasticity. It is possible to prevent the force from easily jumping out of the pressing cylinder. As a result, the pen core can be exposed and immersed normally.

In this way, by the time the clip is pushed backwards and approaches the inner wall at the rear of the working groove, the return spring can be made to have not only reached or already reached the maximum elastic force, so that the clip can be pushed to the maximum. Does not occur easily. In addition, the compressive force of the return spring is small (and therefore the rebound force is small), so that the pen core cannot easily be ejected from the front cylinder. Further, since the pressing cylinder does not contact or just contacts the rear cylinder lid, in the initial state (that is, the pen core is immersed), the pressing cylinder and the rear cylinder lid are pressed by the clip with a sufficient distance.

Move up until it is higher than the position of the second positioning surface. When the clip is released, the elastic action of the return spring disengages the stopper from the engagement groove, and the clip is released.
It moves forward in the axis. After the return spring reaches its maximum force (that is, the pen core is exposed from the front cylinder), the stop engager back buffers at a short distance due to the action of inertial force, and the stop engager hits the guide surface and is in charge of stopping. The joint and the main second positioning surface can come into contact with each other to limit the position of the stop engagement element.

In the process of pushing the clip 3 in the rear direction to compress the return spring 5, the return spring 5 does not easily bend and slide away from the pressing cylinder 32. At the same time, when the clip 3 is released, the return spring 32 becomes self-made. It is possible to prevent the pen core 8 from easily jumping out of the pressing cylinder 32 due to the action of elastic force, and the pen core 8 can be normally exposed and immersed. Further, the pen core 8 is arranged in the front cylinder 1 and the shaft body 2. A clip 3 for controlling the axial relative sliding of the control pen core 8 in the shaft body 2 is further included, and an operating groove 4 capable of axially sliding the clip 3 in the shaft body 2 is provided on the outer wall of the rear portion of the shaft body 2.

A pen groove is formed between the pen groove and the inner wall of the portion, and the pen core 8 is engaged in the pen groove. When the pen core is immersed, the operator pushes the clip 3 backward, and the clip 3 slides the sliding cylinder 31 and the pressing cylinder 32 rearward along the axial direction of the shaft body 2, and the pressing cylinder 3 The return spring 5 can be pressed and the stop engaging element 7 can be gradually detached from the fixed structure. When the clip 3 is released, the pressing cylinder 32 and the sliding cylinder 31 are generated by the elastic action of the return spring 5.
The pen core 8 is slid forward in the axial direction in the shaft body 2 to expose the pen core 8 outside the front cylinder 1, and the stopper engaging element 7 comes into contact with the fixed structure again and is exposed outside the front cylinder 1. The pen core 8 can be fixed.

As shown in FIG. 2, the distance between the inner wall of the rear portion of the working groove 4 and the rear portion of the clip 3 is equal to or greater than the maximum elastic displacement of the return spring 5 and less than or equal to the distance between the pressing cylinder and the rear cylinder lid. There is, and by the time the clip 3 is pushed backward and approaches the inner wall at the rear of the working groove 4, the return spring 5 has not only reached the maximum elastic force, or can be made to have already reached, so push the clip 3 to the maximum. Does not occur easily. Further, the compressive force of the return spring 5 is small (therefore, the rebound force is small), and the pen core 8 cannot be easily ejected to the outside of the front cylinder 1. In addition, the pressing cylinder 32
Since it does not contact or just contacts the rear cylinder lid 10, in the initial state (that is, the pen core 8 is immersed), there is a sufficient distance between the pressing cylinder 32 and the rear cylinder lid 10 and the pressing cylinder is provided by the clip 3. The return spring 5 can be compressed by driving 32.

As shown in FIGS. 5 to 6, a stop engaging element 7 for engaging the shaft body 2 is fixedly installed in the pushing / pulling means. The stop engager 7 is fixedly installed at the rear portion of the stop block 33, a sliding surface 71 is provided on the rear side portion of the lower end of the stop engager 7, and an auxiliary positioning surface 72 is provided on the front side portion of the lower end of the stop engager 7. Is provided, and a hook engaging body is formed between the sliding surface 71 and the auxiliary positioning surface 72, and the hook engaging body and the fixed structure are engaged and connected. When the pen core 8 is immersed, the hook engaging body engages the fixed structure. When the pen core 8 is exposed outside the front cylinder 1, the fixed structure acts as a baffle for the hook engaging body after the position is changed, and the hook engaging body cannot easily slide in the shaft body 2. It functions to fix the position of the pen core 8. The stopper engaging element 7 is made of a plastic member. Since it has a certain degree of deformability and resilience in terms of material, it can be manufactured with general plastic.

As shown in FIGS. 7 to 8, a fixed structure for engaging the stopper 7 is fixedly installed on the inner bottom wall at the rear of the shaft body 2, and the fixed structure is located inside the pushing / pulling means. Will be done. The fixing structure includes a fixing block 9 fixedly installed on the inner bottom wall at the rear portion of the shaft body 2 and an engaging groove formed in the fixing block 9, and the fixing block 9 is inside the sliding cylinder 31.

Move forward within. The return spring 5 has the maximum force (that is, the pen core 8 is exposed from the front cylinder 1).
After that, the stop engaging element 7 back buffers at a short distance by the action of inertial force, and the stop engaging element 7 hits the guide surface 92, and the sliding surface 71 and the main second positioning surface 91 come into contact with each other. The position of the stop engagement element 7 can be limited.

In the process in which the surface area of the guide surface is larger than the surface area of the main second positioning surface, the inclination of the main second positioning surface and the guide surface are equal, and the stop engaging element 7 is moved backward and separated from the engagement groove. Since the sliding surface 71 has a sufficient movable distance on the surface of the guide surface 92, the sliding surface 71 is moved to a position higher than the surface having the upper end of the main second positioning surface 91 on the guide surface 92. The stop engaging element 7 is detached from the engaging groove by the elastic action of the return spring 5 and then moved forward in the shaft body 2 beyond the surface of the main second positioning surface 91. It is possible.

The cross-sectional length of the guide surface 92 is larger than the maximum elastic displacement of the return spring 5, and is greater than or equal to the distance between the pressing cylinder 32 and the rear cylinder lid 10. In this way, even when the return spring 5 is pressed to the maximum force by the pressing cylinder 32, the stop engaging element 71 can be prevented from being detached from the guide surface 92 yet. Thereby, in the process of pressing the return spring 5 by the pressing cylinder 32, the stop engaging element 7 can be prevented from being easily disengaged from the engaging groove.

The vertical distance between the rear end of the main second positioning surface and the inner wall of the shaft body 2 is not less than the maximum elastic displacement of the return spring 5 and less than or equal to the distance between the pressing cylinder and the rear cylinder lid. When the return spring 5 has already reached or has just reached the maximum force, the moving vertical distance of the sliding surface 71 on the guide surface 92 is the rear end portion of the main second positioning surface 91 and the shaft body 2. It is more than the vertical distance between the inner walls. When the clip 3 is released by this, the stop engaging element 7 is separated from the engaging groove by the elastic force action of the return spring 5, and then the pen core 8 crosses the surface having the rear end portion of the main second positioning surface 91.
Can be exposed from the front cylinder.

In the initial state, the pen core 8 is immersed in the shaft body 2 and the front cylinder 1.
