Description

Technical Field

[0001] This utility model belongs to the technical field of silkworm breeding equipment, specifically relating to a silkworm cocoon. Background Technology

[0002] The main cocooning tools on the market are square-grid cocoons and spiral-shaped cocooning tools. Square-grid cocoons are generally made of 360g or 420g kraft paper or cardboard and are foldable. They are available in horizontal and vertical styles and have advantages such as reasonable structure, multiple cocooning positions, and high cocooning rate. However, due to the paper material, they are inconvenient for later storage and disinfection. Spiral-shaped cocoons are a traditional tool made of rice straw and other materials. They are simple to make and have low cost, but they produce many second-generation cocoons such as yellow-spotted cocoons and wood-printed cocoons, which are yellowish in color. Harvesting cocoons with these tools is time-consuming and laborious, and the tools have limited uses, are bulky, and inconvenient to store. Therefore, there is a need to develop a cocooning tool that is easy to store, wash, disinfect, and reuse multiple times. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0029] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] like Figures 1-5 As shown, this utility model discloses a silkworm cocoon, including a frame 1, a first skeleton 2, and a second skeleton 3. Several frame 1s are joined end-to-end to form an outer frame body, with adjacent frame 1s rotatably connected. Both ends of the first skeleton 2 and the second skeleton 3 are rotatably connected to the outer frame body. Several first skeletons 2s and several second skeletons 3s are staggered to form an inner frame body, giving the inner frame body multiple square holes. The intersections of the first skeleton 2 and the second skeleton 3 are connected by a snap-fit ​​structure, allowing the first skeleton 2 and the second skeleton 3 to rotate, thus enabling the inner frame body to be folded or unfolded. Combined with the rotatable connections between the frame 1s and between the skeletons and the frame 1s, the entire silkworm cocoon can be folded or unfolded. Positioning blocks are also provided on the side walls of the first skeleton 2 and the second skeleton 3 for gripping and positioning during silkworm cocoon assembly.

[0031] Specifically, the snap-fit ​​connection structure includes an elastic limiting part 7, wherein a notch 6 is provided on one frame, and the elastic limiting part 7 is provided at the opening 9 end of the notch 6. One end of the elastic limiting part 7 is fixedly connected to one frame, and the other end of the elastic limiting part 7 is a free end. A limiting hole 8 adapted to the elastic limiting part 7 is provided on another frame. Since one end of the elastic limiting part 7 is a free end and the elastic limiting part 7 has elastic properties, the inner wall of the notch 6 and the elastic limiting part 7 form an annular hole that can be opened and closed on one side, which facilitates quick connection or disassembly between the first frame 2 and the second frame 3; and the setting of the elastic limiting part 7 prevents the two from falling off. During installation, the upper or lower side of the other frame presses the elastic limiting part 7, so that the upper or lower side of the other frame is inserted into the notch 6 on one frame, and at the same time, the free end of the elastic limiting part 7 is inserted into the limiting hole 8 on the other frame.

[0032] It should be noted that opening 9 can be provided on the other frame, or it can be omitted; both methods allow rotation between the two frames. The key to whether or not to provide opening 9 depends on the depth of notch 6. If the depth of notch 6 is large, then opening 9 can be omitted. Figure 5 As shown; if the depth of notch 6 is small, opening 9 can be set, such as Figure 4 As shown.

[0033] There are several ways to arrange the snap-fit ​​connection structure on the first frame 2 and the second frame 3. For example, the first frame 2 may have several notches 6 along its length on its upper or lower side, with an elastic limiting part 7 fixedly installed at the opening 9 of each notch 6. The second frame 3 may have several limiting holes 8 along its length, corresponding to the position and size of the elastic limiting part 7. Similarly, the notches 6 may be arranged on the upper or lower side of the second frame 3, and the limiting holes 8 may be arranged on the first frame 2. Alternatively, the upper or lower side of the first frame 2 or the second frame 3 may have several notches 6 and limiting holes 8 arranged alternately along its length. As long as the intersection of the first frame 2 and the second frame 3 satisfies the condition that one frame has a notch 6 and an elastic limiting part 7, and the other frame has a corresponding limiting hole 8, the functions of rotation, quick connection, or disassembly between the first frame 2 and the second frame 3 can be realized. The arrangement of the notches 6 and limiting holes 8 on the first frame 2 and the second frame 3 can be customized according to actual needs.

[0034] It should be noted that the rotatable connection between two adjacent frame 1 can be achieved by means of pin connection, hinge, etc. The rotatable connection between the ends of the first frame 2 and the second frame 3 and the frame 1 can be achieved by means of pin connection, hinge, etc.

[0035] The first skeletons 2 can be arranged at equal or unequal intervals, and the second skeletons 3 can be arranged at equal or unequal intervals. In a preferred embodiment, when the silkworm cocoon unfolds, a plurality of first skeletons 2 are arranged in parallel with equal intervals, and a plurality of second skeletons 3 are arranged in parallel with equal intervals.

[0036] Furthermore, in order to achieve rapid installation, the implementation of the snap-fit ​​connection structure can be as follows: the snap-fit ​​connection structure includes a set of elastic limiting parts 7, and each notch 6 has an opening 9 end provided with a set of elastic limiting parts 7. Each set of elastic limiting parts 7 includes two elastic limiting parts 7, and the free ends of the two elastic limiting parts 7 correspond to each other, so as to realize the rapid installation or disassembly between the first frame 2 and the second frame 3 and avoid the frames from falling off.

[0037] The implementation of the snap-fit ​​connection structure can also be as follows: Figures 1-3As shown, the snap-fit ​​connection structure includes two sets of elastic limiting parts 7. Both the first frame 2 and the second frame 3 have notches 6. Each notch 6 has an elastic limiting part 7 at its opening 9 end. Each set of elastic limiting parts 7 includes two elastic limiting parts 7, with their free ends corresponding to each other, enabling quick installation or disassembly between the first frame 2 and the second frame 3, preventing the frames from detaching. Both the first frame 2 and the second frame 3 have limiting holes 8 that fit each set of elastic limiting parts 7. In this embodiment, for each snap-fit ​​connection structure, if the first frame 2 has a notch 6 on its upper side, then the second frame 3 has a notch 6 on its lower side; or, if the first frame 2 has a notch 6 on its lower side, then the second frame 3 has a notch 6 on its upper side.

[0038] In a preferred embodiment, two elastic limiting parts 7 are symmetrically arranged at the opening 9 end of each notch 6. The free ends of the two elastic limiting parts 7 are inclined toward the inside of the notch 6, so that the two elastic limiting parts 7 form a V-shaped limiting structure. The limiting hole 8 is set as a matching V-shaped limiting hole 8.

[0039] The rotational connection between adjacent frame 1 can be as follows: one end of frame 1 is provided with a first pin hole, and the other end is provided with a first pin shaft or first pin 4 that matches the first pin hole. Alternatively, frame 1 includes a first frame and a second frame, with first pin holes provided at both ends of the first frame, and first pin shafts or first pins 4 that match the first pin holes provided at both ends of the second frame. The pin hole connection method ensures the connection strength between frame 1. It is understood that there are no special requirements as to whether the first pin shaft, first pin 4, or first pin hole is located at either end or one end of frame 1, as long as the connection between two adjacent frame 1s is a pin hole fit.

[0040] The rotatable connection between the frame 1 and the first frame 2 and the second frame 3 can be achieved by: The frame 1 having several second pin holes, and the first frame 2 and the second frame 3 having second pins or second pins 5 at both ends that fit the second pin holes; or, the frame 1 having several second pin holes, and the first frame 2 and the second frame 3 having second pin holes at both ends that fit the second pin holes; or, the frame 1 having several second pin holes, and the first frame 2 and the second frame 3 having second pins or second pins 5 at both ends that fit the second pin holes; or, the frame 1 having several second pin holes, and the first frame 2 and the second frame 3 having second pin holes at both ends that fit the second pin holes. This pin hole connection method ensures the connection strength between the frame 1 and the first frame 2 and the second frame 3. There are no special requirements as to whether the second pin, second pin 5, or second pin hole is set on the frame 1 or on the first frame 2 or the second frame 3, as long as the connection between the frame and the frame 1 is a pin hole fit.

[0041] Furthermore, the frame 1, the first frame 2, and the second frame 3 are made of plastic. The plastic material can be PP, PE, PVC, etc. In a preferred embodiment, the frame 1, the first frame 2, and the second frame 3 are injection molded from PP material, and the frame 1 and the frame are designed with pin holes, which makes the product lightweight, easy to store and stack, occupies little space, and facilitates later cleaning and disinfection.

[0042] Furthermore, the surfaces of the frame 1, the first skeleton 2, and the second skeleton 3 are provided with absorbent layers. These absorbent layers can be made of polymer materials, ensuring the silkworm cocoons remain dry during cocooning, reducing yellow spots on the cocoons, and resulting in whiter cocoons.

[0043] Furthermore, the surfaces of the frame 1, the first skeleton 2, and the second skeleton 3 are provided with rough surfaces, which can be tiger stripes or other forms. By providing rough surfaces, the weight of the product can be reduced and the product's adhesion area can be increased.

[0044] Furthermore, the silkworm cocoon of this application also includes a detachable rotating rod. One end of the rotating rod is adapted to the holes in the inner frame body. By inserting one end of the rotating rod into the holes, the entire silkworm cocoon can be rotated, giving it a rotational function. This eliminates the need for manual turning, making operation convenient and labor-saving. In a preferred embodiment, the holes in the middle of the inner frame body are selected to fit one end of the rotating rod, making turning the silkworm cocoon even easier. If all the holes in the inner frame body are of the same size, turning the silkworm cocoon only requires inserting one end of the rotating rod into any hole in the cocoon, without needing to pay special attention to the specific hole that fits the rotating rod, making operation convenient.

[0045] The working principle of a silkworm cocoon: At the connection between the first frame 2 and the second frame 3, a notch 6 is provided on the upper or lower side of one frame. Two elastic limiting parts 7 are provided at the opening 9 end of the notch 6. One end of each elastic limiting part 7 is fixedly connected to one frame, and the other ends of both elastic limiting parts 7 are free ends and correspondingly positioned. A limiting hole 8 is provided on the other frame. During installation, the lower or upper side of the other frame presses the free ends of the two elastic limiting parts 7 inward (here, "inner side" refers to the inside of the notch 6) and inserts them into the notch 6. The two elastic limiting parts 7 return to their original position under their own rebound force. At this time, the free ends of the two elastic limiting parts 7 fall into the limiting hole 8, interlocking the first frame 2 and the second frame 3 to prevent them from detaching. Adjacent frame edges 1 are connected by pin holes, allowing rotation between adjacent frame edges 1; frame edges 1 are also connected to the first frame 2 and the second frame 3 by pin holes, allowing rotation between frame edges 1 and the first frame 2 and the second frame 3. By rotating the first frame 2, the second frame 3, and the frame 1, the silkworm cocoon can be unfolded or folded up. After the product is assembled, an absorbent layer is applied to ensure a dry environment when the silkworms are mounted, reducing yellow spots on the cocoons and resulting in cleaner cocoons. The product adopts a 169-hole grid design (169 holes refer to the total number of holes in the assembled silkworm cocoon, which can be in a 13*13 configuration), which is more than the traditional square grid cocoon. One hole is used in the middle of the product in conjunction with the rotating rod, allowing the silkworm cocoon to rotate without needing to be turned over, reducing manual turning of the cocoon, making mounting more convenient, less strenuous, and resulting in a higher mounting rate.

[0046] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
