Abstract

The utility model discloses a novel line drawing jig which is characterized by comprising the following components: the middle upper part of a pen holder of the marking pen is annularly provided with a lock head, and the upper end of the lock head is inwards provided with a main shaft mounting groove matched with the main shaft peripheral mounting groove; the lock head is inwards contracted at the lower part of the main shaft mounting groove to form a marking pen clamping part, and is in contact connection with the marking pen through the marking pen clamping part; the main shaft lower extreme inwards cave in with the shape of marker pen clamping part cooperatees and is formed with the spring mounting cavity, the inside shrink in spring mounting cavity upper portion forms right the spring carries out the spacing end of the spacing spring of upward movement, through the spring lets perpendicular up-and-down motion when the atress of marker pen makes the nib department of marker pen hug closely the ya keli board, ensures that the setting-out is continuous. The utility model can solve the problems of non-straight line drawing and intermittent and continuous line drawing of the original engraving machine in the manufacturing process of the LED neon light sign.

Description

Novel line drawing jig

Technical Field

The utility model relates to the field of manufacturing of LED neon signs, in particular to a novel line drawing jig.

Background

When the LED neon sign is manufactured, lines are drawn on an acrylic plate by using an engraving machine, and then the lamp strip is adhered to the positions of the lines. The existing line drawing method of the engraving machine is that the upper end of a marking pen is directly clamped by a lock head matched with a main shaft, and the marking pen is easy to incline and is not concentric with the main shaft in the installation mode, so that the straight line drawing is not straight due to the rotation of the main shaft, and the integral effect of a sticky lamp belt is influenced; when the acrylic plate has unevenness, the condition that the line is broken and continuous can appear in the setting-out, the broken lines need to be artificially supplemented with pictures, the lines supplemented with pictures are unnatural, the adhesive lamp strip is not only influenced, and the working hours are increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above defects in the prior art, the present invention provides a novel line drawing jig. The marking pen moves vertically up and down when stressed, so that the marking pen is tightly attached to the acrylic plate, and continuous line drawing is ensured.

In order to realize the purpose of the utility model, the adopted technical scheme is as follows:

a novel line drawing jig comprises:

the middle upper part of the pen rod part of the marking pen is annularly provided with a lock head, and the upper end of the lock head is inwards provided with a main shaft mounting groove matched with the main shaft peripheral mounting groove;

the lock head is inwards contracted at the lower part of the main shaft mounting groove to form a marking pen clamping part, and is in contact connection with the marking pen through the marking pen clamping part;

the main shaft lower extreme inwards cave in with the shape of marker pen clamping part cooperatees and is formed with the spring mounting cavity, the inside shrink in spring mounting cavity upper portion forms right the spring carries out the spacing end of the spacing spring of upward movement, through the spring lets perpendicular up-and-down motion when the atress of marker pen makes the nib department of marker pen hug closely the ya keli board, ensures that the setting-out is continuous.

In a preferred embodiment of the utility model, the spindle, spring and marker are coaxially arranged.

In a preferred embodiment of the utility model, the lower end of the locking head is positioned below the centerline of the shaft of the marker pen.

In a preferred embodiment of the utility model, a spring mounting part is arranged at the top of the pen holder part of the marking pen, and the spring is sleeved on the periphery of the spring mounting part.

The utility model has the beneficial effects that:

the utility model can solve the problems of non-straight line drawing and intermittent and continuous line drawing of the original engraving machine in the manufacturing process of the LED neon light sign.

The problem that staff manually supplement line drawing strips or draw lines again due to poor line drawing of the engraving machine is avoided; the problem that the pasting effect of the lamp strip is not attractive due to askew reference drawing and line supplementing drawing is avoided. Thereby improving the production efficiency and the product quality of the label.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the novel line drawing jig includes a marking pen 100, a locking head 200 is annularly disposed on the middle upper portion of a pen rod portion 110 of the marking pen 100, and a spindle mounting groove 210 matched with a spindle 300 outer circumference mounting groove 310 is inwardly disposed on the upper end of the locking head 200. The lower end of the locking head 200 is positioned below the centerline of the shaft portion 110.

The lock head 200 is inwardly contracted at the lower part of the main shaft mounting groove 210 to form a marking pen clamping part 220, the marking pen clamping part 220 is in contact connection with the marking pen 100, the lower end of the main shaft 300 is inwardly sunken and is matched with the marking pen clamping part 220 in shape to form a spring mounting cavity 230, the upper part of the spring mounting cavity 230 is inwardly contracted to form a spring limiting end 231 for limiting the upward movement of the spring 400, a spring mounting part is arranged at the top of the pen shaft part 220 of the marking pen, and the spring is sleeved on the periphery of the spring mounting part.

So that the spindle 300, the spring 400, and the marker 100 are coaxially disposed.

The marking pen 100 moves vertically up and down when being stressed by the spring 400, so that the pen point 120 of the marking pen 100 is tightly attached to the acrylic plate, and the continuous drawing is ensured.
