TECHNICAL FIELD
[0001] The utility model relates to the technical field of wet method flower basket, specifically a length adjustable rack and pinion and its flower basket. BACKGROUND
[0002] In the wet method flower basket, the rack and pinion is the main component for supporting the silicon wafer, and its length is usually determined according to the number of silicon wafers to be placed in the flower basket. The structure of the rack and pinion generally includes a cylindrical connecting rod, and a row of uniformly spaced and integrally formed teeth are arranged on the outer wall of the connecting rod along the axial direction. These teeth are used to clamp or support the silicon wafer to prevent it from moving or falling off during the processing.
[0003] However, the existing rack and pinion design has a significant limitation: since the length of the rack and pinion is fixed, when the number of silicon wafers in the flower basket needs to be adjusted, different length rack and pinions must be replaced. This design not only increases production costs, but also requires separate inventory management for rack and pinions that are not suitable, and when there are many models, the rack and pinions require a large storage space. SUMMARY
[0004] To solve the technical problems in the background art, the utility model discloses a length adjustable rack and pinion and its flower basket.
[0005] The utility model provides a length adjustable rack and pinion, which comprises a rack and pinion, and the rack and pinion is composed of multiple rack and pinion segments;
[0006] The rack and pinion segments are provided in multiple models with different lengths, and the number of limiting teeth on each rack and pinion segment is inconsistent;
[0007] The two ends of the rack and pinion are also provided with a first segment and a tail segment;
[0008] One end of the first segment and the tail segment is connected with the rack and pinion segment, and the other end is connected with the side plate of the fixed flower basket;
[0009] The two ends of the rack and pinion segment, one end of the first segment connected with the rack and pinion segment, and one end of the tail segment connected with the rack and pinion segment are all provided with a tooth lobe, and the two tooth lobes are spliced into a complete limiting tooth.
[0010] According to the number of silicon wafers to be placed in the flower basket, the rack and pinion segments are selected for splicing, so that the number of limiting teeth is one more than the number of silicon wafers. The beneficial effects of this arrangement are: 1. Multiple rack and pinions of different lengths can be formed by splicing the rack and pinion segments, which reduces the amount of raw materials used compared to setting multiple integrally formed rack and pinions of different lengths, not only reducing costs, but also saving storage space due to the shorter length of the rack and pinion segments; 2. The spliced part of the rack and pinion is located at the limiting tooth, so even if the limiting tooth at the spliced part is worn out, the distance between the limiting teeth can still be kept constant.

[0013] When the rack rod is subjected to an axial tension, the rack rod segments, the first segment and the tail segment are prone to disengagement, resulting in the flower basket being scattered, based on this, further improvement lies in that the bottom of the socket extends radially with an arc-shaped clamping slot; one end of the clamping slot is connected with the limiting slot; when the positioning block abuts against the socket bottom, it is clamped in the clamping slot in a rotating manner. The limiting slot provides axial limitation among the rack rod segments, the first segment and the tail segment, and the limitation forms a resistance when the rack rod is subjected to an axial tension, and the disengagement phenomenon does not occur.
[0014] The second structure of the rack rod is that the cross sections of the socket and the plug rod are regular polygons.
[0015] For the above-mentioned second structure, when the rack rod is subjected to an axial tension, the rack rod segments, the first segment and the tail segment are also prone to disengagement, resulting in the flower basket being scattered, based on this, further improvement lies in that the rack rod segment, the first segment and the tail segment are all provided with an axially extending connecting hole; a connecting rod is inserted into the connecting hole; both ends of the connecting rod are threaded segments and are fixedly connected with the side plates.
[0016] The third structure of the rack rod is that the rack rod segment, the first segment and the tail segment are all provided with an axially extending socket with a regular polygonal end face; a fixed rod with a cross section shaped according to the socket is inserted into the socket; both ends of the fixed rod are provided with threaded segments and are fixedly connected with the side plates.

By such arrangement, the length of the flower basket is adjustable, and the diversity of the use of the flower basket is realized.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0042] The toothed rod 1 is also provided with a first section 3 and a tail section 4 at both ends; one end of the first section 3 and the tail section 4 is connected to the toothed rod section 2, and the other end is connected to the side plate 5 that fixes the flower basket.
[0043] The specific structure of the rack 1 is as follows: one end of the rack segment 2, the end where the first segment 3 connects to the rack segment 2, is provided with a circular insertion hole 22; the other end of the rack segment 2, the end where the tail segment 4 connects to the rack segment 2, is provided with a circular insertion rod 23. When the rack 1 is assembled, the insertion rod 23 is inserted into the insertion hole 22.
[0044] The hole wall of the insertion hole 22 is provided with a concave, axially extending limiting groove 24, and the side wall of the insertion rod 23 is provided with a convex positioning block 25 for clamping the limiting groove 24, thereby improving the positional stability of the tooth rod segment 2, the first segment 3 and the tail segment 4 after splicing, and avoiding relative rotation.

The limiting groove 24 provides axial limitation between the tooth rod segments 2, between the tooth rod segment 2 and the first segment 3, and between the tooth rod segment 2 and the tail segment 4. This limitation forms resistance when the tooth rod 1 is subjected to axial tension, and does not appear to be detached.

[0050] The tooth rod segment 2, the first segment 3 and the tail segment 4 are all provided with axially extending connecting holes 6; the connecting holes 6 are inserted with connecting rods 7, and the connecting rods 7 are fixedly connected with the side plates 5 of the flower basket. The connecting rods 7 can improve the stability of the mounting structure of the tooth rod 1, and when the tooth rod 1 is subjected to axial tension, it will not be detached, thereby preventing the flower basket from being scattered. The connecting rods 7 are provided in multiple lengths, which still simplifies the structure and saves costs compared to setting tooth rods 1 of different lengths.
[0051] Embodiment Three:
[0052] Compared with Embodiment One, the difference is that, as shown in Figures 14-16As shown, the tooth bar section 2, the head section 3 and the tail section 4 are provided with the axially extending and end face regular polygonal insertion holes 8, which are regular hexagons in the embodiment; and the tooth bar section 2 is not provided with the insertion hole 22 and the insertion rod 23, the head section 3 is not provided with the insertion hole 22, and the tail section 4 is not provided with the insertion rod 23.
[0053] The insertion hole 8 is inserted with the fixed rod 9 with the same cross section as the insertion hole 22; and the fixed rod 9 is fixedly connected with the side plate 5.
[0054] The fixed rod 9 is provided with multiple lengths, which still simplifies the structure and saves the cost compared to the tooth bar 1 with different lengths.
