Description

TECHNICAL FIELD

[0001] The utility model relates to stationery field, especially a kind of intelligent posture correction pen. BACKGROUND

[0002] Correct pen holding angle usually suggests that pen barrel and desktop are 65~70 degrees of inclination, so that it can ensure clear vision when writing, and at the same time, wrist is in relaxed state, and incorrect pen holding angle can cause adverse effects on hand health, for example, thumb pressing index finger holding posture can cause middle finger pain, callus and even joint deformation, hand is tired and sore due to tightness, writing range is limited, font is small and writing speed is slow, so correct writing habit should be cultivated when children start learning writing, but writing habit is not immediately formed, and long-term persistence is needed, and it is difficult to achieve to supervise children's writing posture at all times. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims at providing an intelligent posture correction pen to solve the current pain points in the field.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] An intelligent posture correction pen, comprising a pen tube, a pen core is arranged in the pen tube, the pen core can move vertically in the pen tube, a rotating drum is vertically rotatably installed on the upper portion of the pen tube, a horizontal block is rotatably installed on the upper portion of the rotating drum with a horizontal shaft as the center, a counterweight block is fixedly installed on the bottom of the horizontal block, one end of each of two connecting rods is hingedly connected to the two ends of the horizontal block, the other end of each of the connecting rods is hingedly connected to a synchronous block, the distance between the hinging points on the synchronous block is the same as that of the horizontal block, the synchronous block is rotatably installed on the bottom of the rotating drum, a top rod is fixedly installed on the synchronous block, there is an included angle between the top rod and the synchronous block, a pressing plate is slidably installed in the pen tube, the pressing plate is arranged between the pen core and the top rod, when the top rod is parallel to the pen tube, the top rod can press against the pressing plate to fix the pen core.

[0006] Further, the included angle between the top rod and the synchronous block is between 65° and 70°.

[0007] In summary, the utility model has the beneficial effects compared with the prior art: when the pen tube is inclined at a correct angle, the horizontal block remains horizontal under the action of the counterweight block, and the top rod remains horizontal through the connecting rod, so that the top rod can be in a horizontal state with the pen tube, so as to press the pressing plate at the longest distance, thereby fixing the pen core, if the pen tube is inclined at too large or too small angle, the top rod will be deflected, so that the pressing plate is loose, at this time, the pen core cannot be fixed, and cannot be normally used for writing, so that the writer can maintain correct writing posture when using the pen. BRIEF DESCRIPTION OF DRAWINGS

[0008] The above and other objects, features and advantages of the present application will become more apparent from the following detailed description read in conjunction with the accompanying drawings, in which:

[0009] Figure 1 It is a structure diagram of an intelligent posture correction pen.

[0010] Reference signs: 1, pen tube; 2, pen core; 3, rotating drum; 4, horizontal block; 5, counterweight block; 6, connecting rod; 7, synchronous block; 8, top rod; 9, pressing sheet. DETAILED DESCRIPTION

[0011] The present application will be further described in conjunction with the accompanying drawings.

[0012] An intelligent posture correction pen comprises a pen tube 1, a pen core 2 is arranged in the pen tube 1, the pen core 2 can move vertically in the pen tube 1, a rotating drum 3 is vertically rotatably arranged on the upper portion of the pen tube 1, a horizontal block 4 is rotatably arranged on the upper portion of the rotating drum 3 with a horizontal shaft as the center, a counterweight block 5 is fixedly arranged on the bottom of the horizontal block 4, the counterweight block 5 can keep the horizontal block 4 horizontal even if the pen tube 1 is inclined, a connecting rod 6 is hingedly arranged on each end of the horizontal block 4, the other end of the connecting rod 6 is hingedly arranged on a synchronous block 7, the synchronous block 7 is rotatably arranged on the bottom of the rotating drum 3, the distance between the hinging points on the synchronous block 7 is the same as that of the horizontal block 4, a top rod 8 is fixedly arranged on the synchronous block 7, the included angle between the top rod 8 and the synchronous block 7 is between 65° and 70°, a pressing sheet 9 is slidably arranged in the pen tube 1, the pressing sheet 9 is arranged between the pen core 2 and the top rod 8, when the top rod 8 is parallel to the pen tube 1, the top rod 8 can press against the pressing sheet 9, so that the pressing sheet 9 presses the pen core 2, the pen core 2 is fixed with the pen tip extending out of the bottom end of the pen tube 1.

[0013] When the pen tube 1 is inclined at a correct angle, the horizontal block 4 keeps horizontal under the action of the counterweight block 5, and the connecting rod 6 keeps the top rod 8 horizontal, so that the top rod 8 can be kept horizontal with the pen tube 1, and the top rod 8 can press against the pressing sheet 9 at the longest distance, so that the pen core 2 is fixed, if the pen tube 1 is inclined at too large or too small an angle, the top rod 8 will be deflected, so that the pressing sheet 9 is loosened, at this time, the pen core 2 cannot be fixed, and cannot be used for writing normally.

[0014] The above only describes exemplary embodiments of the present application, and is not used to limit the protection scope of the present application, the protection scope of the present application is determined by the appended claims.
