Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological breeding and relates to a connection structure of a hanger and a hatching tray. Background Art
[0002] Maggots, the larvae of houseflies, have a nutritional profile similar to high-quality fish meal, containing approximately 55%-65% protein and rich in various amino acids. They are a high-quality animal protein feed that can meet the domestic aquaculture industry's demand for high-protein feed. Currently, during maggot farming, the hatching trays used for maggot farming are typically moved using a pallet transport rack. This rack typically consists of four columns and several support plates axially arranged on the four columns. The hatching trays are placed sequentially on the support plates, and casters are installed at the bottom of the four columns. During transport, if the rack encounters bumps, rapid movement, or sudden stops, the hatching trays on the same support plate are prone to collision, and may even cause the hatching trays to detach from the plate. Summary of the Invention
[0003] The purpose of the present invention is to solve the above problems in the existing technology and propose a connection structure between a hanger and an incubation tray. The technical problem to be solved by the present invention is how to improve the stability of the connection between the incubation tray and the hanger.
[0004] The purpose of this utility model can be achieved through the following technical solutions:
[0005] A connection structure between a hanger and an incubation tray, characterized in that the hanger includes a main rod and a bracket radially arranged on the main rod, the connection structure includes an elastic positioning piece fixedly connected to the bracket, and the two sides of the elastic positioning piece respectively have upwardly bent side wings, and the two sides of the incubation tray have positioning grooves. When the incubation tray is placed on the bracket, the two side wings of the elastic positioning piece are respectively and simultaneously engaged in the positioning grooves on both sides of the incubation tray under the action of elastic force.
[0006] By providing an elastic positioning piece whose side wings can be elastically deformed along the radial direction of the main rod, when in use, the user only needs to align the positioning grooves on both sides of the incubation tray with the two side wings of the elastic positioning piece respectively, and then the user presses the incubation tray down with force until the bottom of the incubation tray abuts against the bracket, and the two side wings of the elastic positioning piece can be respectively and simultaneously engaged in the positioning grooves on both sides of the incubation tray to fix the relative positions of the bracket and the incubation tray, thereby improving the stability of the connection between the incubation tray and the hanger. When the incubation tray needs to be removed, the user just lifts the incubation tray with force until the positioning grooves on both sides of the incubation tray are simultaneously disengaged from the two side wings of the elastic positioning piece.
[0007] In the aforementioned connection structure between a hanger and an incubation tray, the incubation tray's positioning groove includes a positioning protrusion extending along the tray's width. The upper side of the positioning protrusion is tilted from top to bottom and from inward to outward, while the lower side of the positioning protrusion is tilted from top to bottom and from outward to inward. The side wings of the elastic positioning piece include a snap-fit groove that matches the shape of the positioning protrusion. The positioning protrusion in this structure allows the positioning protrusion to form a mutually restraining position with the sidewalls of the snap-fit groove when it is engaged in the snap-fit groove. The user needs to forcefully press down or lift up on the incubation tray to engage or disengage the positioning protrusion.
[0008] In the aforementioned structure for connecting a hanger to an incubation tray, the angle of inclination of the upper side of the positioning protrusion relative to the bottom of the incubation tray is greater than the angle of inclination of the lower side of the positioning protrusion relative to the bottom of the incubation tray. This structure makes the upper side of the positioning protrusion steeper than the lower side, making it easier for the positioning protrusion to engage with the engaging groove and more difficult to disengage from the engaging groove.
[0009] In the aforementioned connection structure between a hanger and an incubation tray, the elastic positioning piece includes a plate-shaped base and two side wings integrally connected to the base at both ends. The base is connected to a bracket, and the top ends of the side wings are tilted upward from the inside to the outside and are provided with reinforcement notches. The bottom of the elastic positioning piece is plate-shaped, which can increase the contact area between the elastic positioning piece and the incubation tray, allowing the incubation tray to be placed more stably on the bracket. The provision of the reinforcement notches and the integrally formed structure can enhance the structural strength of the elastic positioning piece. At the same time, the top ends of the side wings are tilted upward from the inside to the outside, allowing the two side wings of the elastic positioning piece to better undergo elastic deformation along the radial direction of the main rod.
[0010] In the aforementioned structure connecting the hanger and the incubation tray, the bracket includes a plurality of support rods arranged vertically and horizontally. Each support rod has a plurality of upwardly protruding stoppers, which are located at least on the outer sides of the two side wings of the elastic positioning piece and on the outer sides of the two ends of the incubation tray. This arrangement of support rods vertically and horizontally reduces the weight of the bracket while maintaining structural strength. The stoppers further limit the horizontal movement of the incubation tray, thereby further improving the stability of the connection between the incubation tray and the bracket.
[0011] In the aforementioned structure connecting the rack and incubation tray, the bracket is connected to the main rod via two connecting plates, which are symmetrically arranged relative to the main rod. These connecting plates enhance the bracket's structural strength while facilitating assembly and disassembly of the bracket from the main rod. Furthermore, the symmetrical arrangement of the two connecting plates on the main rod ensures that the center of gravity of the entire rack remains constant after the brackets are installed.
[0012] Compared with the prior art, the connection structure of the present hanger and the incubation tray has the following advantages: when the incubation tray is placed on the bracket, the two side wings of the elastic positioning piece can be simultaneously engaged in the positioning grooves on both sides of the incubation tray under the action of elastic force to fix the relative positions of the bracket and the incubation tray. In addition, the limiting part on the supporting rod can further limit the horizontal movement of the incubation tray, thereby improving the stability of the connection between the incubation tray and the hanger.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0020] A connection structure between a hanger and a hatching tray, referring to Figure 1-5 The hanger includes a main rod 1 and a bracket 2 radially arranged on the main rod 1. The connecting structure includes an elastic positioning piece 3 fixedly connected to the bracket 2. The two sides of the elastic positioning piece 3 respectively have upwardly bent side wing portions 3a, and the two side wing portions 3a can be elastically deformed to move closer to or away from each other. The two sides of the incubation tray 4 have positioning grooves 4a. When the incubation tray 4 is placed on the bracket 2, the two side wing portions 3a of the elastic positioning piece 3 are respectively and simultaneously clamped in the positioning grooves 4a on both sides of the incubation tray 4 under the action of elastic force to fix the relative positions of the bracket 2 and the incubation tray 4.
[0021] Specifically, refer to Figure 1-5The positioning groove 4a of the incubation tray 4 includes a positioning protrusion 4b extending along the width of the incubation tray 4. The upper side of the positioning protrusion 4b is inclined from top to bottom and from the inside to the outside, while the lower side of the positioning protrusion 4b is inclined from top to bottom and from the outside to the inside. The side wing portion 3a of the elastic positioning piece 3 includes a snap-in groove 3a1 that matches the shape of the positioning protrusion 4b. In this embodiment, the upper side of the positioning protrusion 4b is preferably inclined at a greater angle relative to the bottom surface of the incubation tray 4 than the lower side of the positioning protrusion 4b. The elastic positioning piece 3 includes a plate-shaped base portion 3b and two side wing portions 3a integrally connected to each end of the base portion 3b. The base portion 3b is connected to the bracket 2. The top ends of the side wing portions 3a are inclined from the inside to the outside and from the bottom to the inside, and are provided with a reinforcement notch 5.
[0022] More specifically, refer to Figure 1-5 The bracket 2 includes a plurality of support rods 6, and the plurality of support rods 6 are arranged vertically and horizontally. The support rods 6 have a plurality of upwardly protruding limiting portions 6a, and the limiting portions 6a are at least arranged on the outside of the two side wing portions 3a of the elastic positioning piece 3 and the outside of the two end portions of the hatching tray 4; the bracket 2 is connected to the main rod 1 through a connecting plate 7, and the connecting plates 7 are two and symmetrically arranged relative to the main rod 1.
[0023] During use, the user first aligns the positioning grooves 4a on both sides of the hatching tray 4 with the two side wings 3a of the elastic positioning piece 3, and then presses the hatching tray 4 downward with force until the bottom of the hatching tray 4 abuts against the base 3b of the elastic positioning piece 3. At this time, the positioning protrusions 4b in the two positioning grooves 4a are respectively snapped into the engaging grooves 3a1 on the same side of the elastic positioning piece 3, thereby locking the relative positions of the bracket 2 and the hatching tray 4. The limiting portions 6a on the supporting rods 6 are respectively located on the outside of the hatching tray 4 and the elastic positioning piece 3, which can further limit the horizontal movement of the hatching tray 4. It should be noted that there is a gap between the limiting portions 6a and the elastic positioning piece 3, so that the side wings 3a have space to undergo elastic deformation along the radial direction of the main rod 1. When the hatching tray 4 needs to be removed, the user lifts the hatching tray 4 with force until the positioning protrusions 4b on both sides of the hatching tray 4 are simultaneously disengaged from the two engaging grooves 3a1 of the elastic positioning piece 3.
[0024] It should be noted that multiple brackets 2 can be set along the length direction of the main pole 1, a hanging piece can be set on the top of the main pole 1, and then the main pole 1 is hung on the hanging rail to realize the automatic movement of the hanger.
