Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 15 below, the prefabricated material conveying device in the prior art generally needs to meet the following process requirements:
1. forward scale adjustment to achieve a wide adjustment of the scale, i.e. the dose adjustment portion 200;
2. reverse scale adjustment to achieve a small scale callback, i.e. the function of the dose adjusting part 200 as well;
3. in the process of adjusting the positive and negative scales, a good sound prompt needs to be provided, namely, a sound corresponding to each scale change process;
4. when the material is conveyed by pressing, sounding is carried out once every material with one scale is conveyed; thereby realizing the delivery transmission, i.e., the feedback pushing part 300.
However, existing precast material pushing devices of this type have some drawbacks: first, the typical sounding part 100 is composed of three or more parts, and the sounding structure is complex and the number of parts is large; next, the key sounding parts of the general sounding part 100 are disposed in the inner cavity of the outer sleeve 201, and after the assembly is completed, the factory inspection is required, and since the parts are located in the inner cavity, the factory inspection of the sounding part 100 is difficult, and a complicated working time and process are required.
Based on the above pain point, a prefabricated material pushing device with a simpler structure of the sounding part 100 is designed, wherein the prefabricated material pushing device comprises three parts, namely a dose adjusting part 200, the sounding part 100 and a feedback pushing part 300, the dose adjusting part 200 mainly plays the roles of large-scale adjustment and small-scale callback, namely the large-scale adjustment and the small-scale adjustment, and the meaning of the large-scale adjustment is to firstly adjust an indication scale (the scale of the material being conveyed which can be observed by an operator) to be close to a demand scale (the target conveying scale of the operator); the meaning of small dose adjustment is to bring the indication scale close to the target delivery scale into agreement with the target delivery scale. For example, the target delivery scale is 15ml, then the scale is adjusted to 14ml or 15ml or 16ml when large dose adjustment is possible; if the indication scale is 14ml, only one scale position is required to be rotated forward during small dose adjustment; if the indication scale is 15ml, small dosage adjustment is not needed; if the indication scale is 16ml, the scale position is reversely rotated.
The sounding part 100 is mainly used for triggering a sound when the scale is adjusted and the indication scale changes by one scale value. While the sound production in this solution takes the form of an axial play to effect sound production. The meaning of axial play herein is that a portion of the structure of the sound generating part 100 is displaced up and down along the length direction of the preformed material pushing device, thereby triggering sound.
The feedback pushing part 300 is used for realizing the forward pushing effect of the material in the pushing process, and continuously conveying the materials in the feedback pushing process. Note that the dose adjusting section 200, the sound emitting section 100, and the feedback pushing section 300 are linked and linked to each other.
Taking the sounding part 100 as an example, the sounding part 100 includes a button 101, a transmission link 102, a sounding spring 103 and scale vertical teeth 2021; wherein the button 101 is in a cover shape, an annular groove 1011 is arranged outside the button 101, and guide slopes 1012 are arranged at the two upper and lower edges of the annular groove 1011 in a guiding way; the corner of the inner wall of the button 101 is provided with a plurality of bevel angle reinforcing ribs 1013, which are mainly used for enhancing the structural strength of the button 101, the center inside the button 101 is provided with a limit column 1014, the limit column 1014 is circumferentially provided with a plurality of reinforcing ribs 1015, wherein the number of the bevel angle reinforcing ribs 1013 is preferably 6, the number of the reinforcing ribs 1015 is preferably 6, the position of each bevel angle reinforcing rib 1013 can be relatively arranged between two reinforcing ribs 1015, each reinforcing rib 1015 can also be relatively arranged between two bevel angle reinforcing ribs 1013, and the specific number can be provided with different numbers of bevel angle reinforcing ribs 1013 and reinforcing ribs 1015 according to different requirements.
The transmission link 102 is in a rod shape, a circumferential edge 1021 is arranged at the upper end edge of the transmission link 102, a transmission vertical tooth 1022 is arranged at the bottom of the circumferential edge 1021, a transition edge 1023 is arranged below the circumferential edge 1021, the transition edge 1023 is annularly arranged on the side wall of the transmission link 102 and is attached to the circumferential edge 1021, a rotation stopping static head 1024 is arranged at the bottom of the transition edge 1023, and a rotation stopping inclined plane 1025 is arranged at the bottom of the rotation stopping static head 1024; wherein the outer diameter of transition edge 1023 is smaller than the outer diameter of circumferential edge 1021. The cross-sectional shape of the driving vertical teeth 1022 is in the shape of an isosceles triangle, and the number is preferably set to 4. The circumferential edge 1021 is carried over the transition edge 1023, that is, the inner diameter of the circumferential edge 1021 is larger than the inner diameter of the transition edge 1023, so that a carrying cavity is formed, which takes the inner ring side wall of the circumferential edge 1021 and the outer wall of the transmission connecting rod 102 as limiting walls and the upper end surface of the transition edge 1023 as carrying, for limiting and carrying the sounding spring 103. Two flat wires 1026 are arranged on the side wall of the transmission connecting rod 102 in a mirror image manner, a long through groove 1027 is formed in a gap between the two flat wires 1026, two anti-rotation edges 1028 are arranged on the inner wall of the transmission connecting rod 102 in a mirror image manner, each anti-rotation edge 1028 is collinear with one long through groove 1027, and the arrangement of the long through groove 1027 has the following significance:
1.
