Description

Technical Field

[0001] This utility model relates to the field of dispensing needle technology, and in particular to a dispensing needle with an auxiliary clamping device. Background Technology

[0002] Dispensing needles are tools for precise application of adhesives. However, in actual use, the lack of support points when the operator holds the dispensing needle can cause it to wobble and shift during the dispensing process, affecting the accuracy of the application. The Chinese Patent Network published a "Dispensing Needle with Auxiliary Clamping Device" application number "201520038572.9". This dispensing needle improves the stability of the dispensing needle by setting a clamping bar and placing the arc-shaped section of the clamping plate on both sides of the needle. However, due to the poor flexibility of the clamping bar, it is impossible to apply the dispensing material at an angle, which affects the comfort of using the dispensing needle. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a dispensing needle with an auxiliary clamping device, which provides the function of clamping the dispensing point of the dispensing needle, improves the stability of the needle during the dispensing process, improves the flexibility of the clamping component, expands the application range of the dispensing needle, and improves the user comfort of the dispensing needle.

[0004] This utility model also provides a dispensing needle with an auxiliary clamping device, comprising: a needle body, a mounting block slidably connected to the surface of the needle body, a positioning ring fixedly connected to the right surface of the mounting block, the inner wall of the positioning ring being in close contact with the side surface of the needle body, mounting strips and fixing bolts provided on the upper and lower sides of the mounting block, the fixing bolts threadedly connected to the mounting block through the mounting strips, and the mounting strips being rotatably connected to the fixing bolts, and long strip-shaped spring pieces fixedly connected to the left surfaces of the two mounting strips. During dispensing, the ends of the two long strip-shaped spring pieces away from the mounting strips clamp the item to be dispensed, and the ends of the long strip-shaped spring pieces away from the mounting strips have smooth cut surfaces that contact the surface of the item to be dispensed.

[0005] According to the present invention, a dispensing needle with an auxiliary clamping device is provided, wherein the positioning ring has an opening and closing structure, and a buckle is fixedly connected to the end of the positioning ring away from the mounting block. This improves the stability of the positioning ring.

[0006] According to the present invention, a dispensing needle with an auxiliary clamping device is provided, wherein the length of the mounting strip is greater than the thickness and width of the mounting block, and the left end of the mounting strip protrudes from the left surface of the mounting block at any angle. This improves the effectiveness of the strip-type spring.

[0007] According to the present invention, a dispensing needle with an auxiliary clamping device is provided, wherein the elongated spring has an inclined structure, and the two elongated springs form a V-shaped angle. During the dispensing process, the converging end of the V-shaped angle contacts the surface of the item to be glued, thereby improving the effectiveness of the elongated spring.

[0008] According to the present invention, a dispensing needle with an auxiliary clamping device is provided with a round rod on the smooth cross-section surface. During dispensing, the side surface of the round rod contacts the surface of the item to be glued, thereby reducing the friction on the smooth cross-section.

[0009] Beneficial effects:

[0010] Compared with existing technologies, this dispensing needle with an auxiliary clamping device improves the ease of clamping the item to be glued by utilizing the V-shaped structure formed by two long springs and the characteristics of the springs through the mounting block, mounting strip, fixing bolt, and long spring. The structure of the mounting strip sliding relative to the needle body and the structure of the mounting strip rotating relative to the mounting block improve the flexibility of the dispensing needle clamping components, increasing the applicability and comfort of the dispensing needle.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model provides a dispensing needle with an auxiliary clamping device, comprising: a needle body 1, a mounting block 2 slidably connected to the surface of the needle body 1, the mounting block 2 being used to mount and clamp the component to be glued, a positioning ring 3 being fixedly connected to the right surface of the mounting block 2, the inner wall of the positioning ring 3 being in close contact with the side surface of the needle body 1, the positioning ring 3 being an openable structure, and a buckle 4 being fixedly connected to the end of the positioning ring 3 away from the mounting block 2, the positioning ring 3 cooperating with the buckle 4 to increase the friction force on the mounting block 2 and improve the stability of the mounting block 2 during operation, wherein the positioning ring 3 is a commonly used plastic ring with a self-bending and deformable shell.

[0020] Specifically, when using the glue application needle, applying force to the right end of the positioning ring 3 will unfold and merge the buckle 4, thereby changing the restriction of the buckle 4 on the positioning ring 3. The positioning ring 3 then converts the restriction provided by the buckle 4 into friction force acting on the mounting block 2, thereby increasing the stability of the mounting block 2 during operation. After the buckle 4 and the positioning ring 3 are unfolded, they can slide left and right to change the position of the mounting block 2.

[0021] Mounting block 2 is provided with mounting strips 5 and fixing bolts 6 on both the upper and lower sides. The fixing bolts 6 pass through the mounting strips 5 and are threadedly connected to the mounting block 2. The mounting strips 5 and fixing bolts 6 are rotatably connected. The length of the mounting strips 5 is greater than the thickness and width of the mounting block 2, and the left end of the mounting strips 5 protrudes from the left surface of the mounting block 2 at any angle. The left surfaces of the two mounting strips 5 are fixedly connected to long strip springs 7. When applying glue, the ends of the two long strip springs 7 away from the mounting strips 5 clamp the item to be glued. The long strip springs 7 have an inclined structure, and the two long strip springs 7 form a V-shaped angle. When applying glue, the converging end of the V-shaped angle contacts the surface of the item to be glued. The above components cooperate to form a clamping mechanism to clamp the item to be glued, improving the stability of the glue dispensing needle.

[0022] Specifically, during the use of the dispensing needle, the two elongated springs 7 utilize their elastic deformation to adapt to different widths of the items to be glued, and the feed amount of the fixing bolt 6 is changed by rotating the fixing bolt 6, thereby changing the clamping friction force applied by the mounting block 2 and the fixing bolt 6 to the mounting strip 5. When the friction force decreases, the mounting strip 5 can be manually rotated and tilted to change the tilt angle of the elongated spring 7 relative to the glue dispensing end of the needle body 1.

[0023] The long strip spring 7 has a smooth cut surface 8 at the end away from the mounting strip 5. The smooth cut surface 8 contacts the surface of the item to be glued. The smooth cut surface 8 is used to increase the contact area between the long strip spring 7 and the item to be glued. A round rod 9 is provided on the surface of the smooth cut surface 8. When applying glue, the side surface of the round rod 9 contacts the surface of the item to be glued. The round rod 9 rotates relative to the long strip spring 7 to reduce the friction force on the long strip spring 7. The round rod 9 is embedded inside the long strip spring 7. In the attached figure, the round rod 9 is in a partially removed state.

[0024] Specifically, during the use of the dispensing needle, the long strip spring 7 is affected by the smooth cut surface 8, which increases the contact area with the surface of the item to be glued. When moving left and right to change the glue application point, the round rod 9 rotates due to friction, thereby reducing the friction between the long strip spring 7 and the item to be glued.

[0025] Working principle: The contact buckle 4 restricts the right end of the positioning ring 3, allowing the right end of the positioning ring 3 to unfold. Without the frictional restriction of the right end of the positioning ring 3, the mounting block 2 can slide left and right. When using the dispensing needle, first adjust the distance between the mounting block 2 and the dispensing end of the needle body 1 according to the height of the item to be glued. If the height of the item to be glued is large, slide the mounting block 2 to the left, and if the height of the item to be glued is small, slide the mounting block 2 to the right. This ensures the stability of the two long strip springs 7. When tilting the glue, loosen the fixing bolt 6 to restrict the mounting strip 5, allowing the mounting strip 5 to rotate. However, during rotation, it is still restricted by the frictional force between the mounting block 2 and the fixing bolt 6. At this time, the mounting strip 5 is in a state where it can be rotated but remains stable. This achieves the change of the working angle of the long strip spring 7 while ensuring that the long strip spring 7 has sufficient stability, without the need to frequently loosen and tighten the fixing bolt 6.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
