Description

Technical Field

[0001] This utility model relates to the field of animal experimental equipment technology, and in particular to an adjustable frame for an experimental animal breeding cage. Background Technology

[0002] Laboratory animals are kept in cages during scientific experiments, drug production, and testing of biological products. Multiple animal cages are placed on shelves to allow for independent feeding and centralized management of the laboratory animals in order to facilitate the conduct of experiments.

[0003] Animal cage racks typically consist of a multi-layered frame structure composed of several horizontal bars (or plates) and several vertical bars (or plates). Each layer forms a storage platform for one or more animal cages. In the existing technology, such racks are generally customized according to the size and quantity of the animal cages, meaning the layer spacing, horizontal cage spacing, and outer frame dimensions are all fixed. In the market, the sizes of animal cages produced by different manufacturers vary. Therefore, manufacturers of animal cages usually produce corresponding racks to match. This has adverse effects on the market and consumers. Specifically: consumers have fewer choices when purchasing racks or cages independently (when purchasing cages alone, they need to consider the fixed dimensions of existing racks, and when purchasing racks alone, they also need to consider the dimensions of existing cages), which can easily lead to market monopolies and unfair competition (binding cages and racks together), waste of resources, and increased procurement costs (cages and racks may be mismatched and left idle, and the inability to purchase cages or racks independently as needed increases procurement costs). Therefore, the existing cages for raising experimental animals have shortcomings such as poor versatility and weak independence. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a more versatile animal cage rack that can solve the market monopoly problem caused by the fixed size of independent ventilated plastic cages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable frame for an experimental animal rearing cage, characterized in that it includes a frame with a hexahedral outer contour, the frame including a quadrilateral top frame, a quadrilateral bottom frame, two front side pillars and two back side pillars, the top frame being parallel to the bottom frame, the two front side pillars and the two back side pillars being fixedly connected between the top frame and the bottom frame, a plurality of first adjustable pillars in the same vertical plane as the two front pillars being connected between the top frame and the bottom frame, and a plurality of second adjustable pillars in the same vertical plane as the two back pillars being connected between the top frame and the bottom frame, the first adjustable pillars and the second adjustable pillars corresponding one-to-one, a plurality of horizontally arranged crossbars being provided between the front side pillars and the back side pillars on the same side, and between the first adjustable pillars and the corresponding second adjustable pillars, the crossbars being provided with at least one carrier plate; the spacing between adjacent first adjustable pillars and the spacing between adjacent second adjustable pillars are adjustable.

[0006] Furthermore, the longitudinal position of the crossbar on the front side post, back side post, first adjustable post, and second adjustable post connected to it is adjustable.

[0007] Furthermore, the position of the carrier plate on the crossbar along the length of the crossbar is adjustable.

[0008] As one of the adjustable connection methods for the rods, the top frame strips of the front side column, the back side column, the first adjustable column, the second adjustable column, the crossbar, and the bottom frame strips of the vertical crossbar all have inwardly flanged U-shaped grooves. Each end of the crossbar has a T-shaped connecting piece. The upper and lower ends of the front side column, the back side column, the first adjustable column, and the second adjustable column each have triangular connecting pieces. The T-shaped connecting pieces, the triangular connecting pieces, and the carrier pieces all have multiple locking bolts. Each locking bolt includes a screw rod, a nut fixed to the outer end of the screw rod, and a nut threaded onto the screw rod. The nut can slide within the inwardly flanged U-shaped groove while restricting rotation.

[0009] Of course, other existing technologies that enable one rod to slide on another rod and be fixed in the slid position can also be implemented, such as guide rail type, multi-hole positioning type, screw type, etc.

[0010] Furthermore, it also includes an intake main pipe located below the outer side of the rear side pillar and an exhaust main pipe located above the outer side of the rear side pillar. Several ventilation branches are connected in parallel between the intake main pipe and the exhaust main pipe, and air inlet hoses that can be connected to animal feeding cages are connected in parallel to the ventilation branches.

[0011] Furthermore, there are two symmetrically distributed carrier plates on the same crossbar, and the outer ends of the carrier plates have upward-turned limiting flanges.

[0012] Furthermore, a ground wheel is provided at each of the four corners of the bottom frame.

[0013] The top frame, bottom frame, two front side columns, and two back side columns form the outline of the adjustable frame. Of course, taking the adjustable frame as a reference, the members set along the X-axis include the front horizontal tie rod of the top frame, the back horizontal tie rod of the top frame, the front horizontal tie rod of the bottom frame, and the back horizontal tie rod of the bottom frame. The members set along the X-axis include the front side columns, the back side columns, the first adjustable column, and the second adjustable column. The members set along the Z-axis include the crossbars and the members on the top and bottom frames that are parallel to the crossbars.

[0014] Animal cages are placed between adjacent horizontal bars. The support plate serves as the longitudinal support and limiting element for the cage, while the limiting edge restricts the cage's position along the length of the horizontal bars. The first adjustable column and its corresponding second adjustable column must be adjusted to a similar degree to ensure the horizontal bars are perpendicular to both. Adjustments to the same cage's placement plane require corresponding longitudinal adjustments to the horizontal bars, and the support plate must also be adjusted accordingly to ensure the cage is placed stably.

[0015] In this solution, the placement area of ​​the animal cages can be adjusted in three dimensions, providing better versatility when adapting to animal cages of different sizes. It offers a wider range of possibilities for the mutual adaptation of cages and racks. Within the compatibility range of the ventilation hose, the three-dimensional space of the cage placement and the two-dimensional plane of the ventilation system are universally compatible. This makes the use cost of cages and racks as supporting products for animal husbandry lower. In addition, it breaks the highly interdependent relationship between the two, which is conducive to healthy market competition. Attached Figure Description

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments. Example

[0019] like Figure 1 and Figure 2 As shown, the device includes a frame with a hexahedral outline. The frame includes a quadrilateral top frame 3, a quadrilateral bottom frame 4, two front side pillars 1, and two back side pillars 2. The top frame 3 is parallel to the bottom frame 4. The two front side pillars 1 and the two back side pillars 2 are fixedly connected between the top frame 3 and the bottom frame 4. Several first adjustable pillars 5, which are in the same vertical plane as the two front pillars, are connected between the top frame 3 and the bottom frame 4. Several second adjustable pillars 6, which are in the same vertical plane as the two back pillars, are connected between the top frame 3 and the bottom frame 4. The first adjustable pillars 5 and the second adjustable pillars 6 correspond one-to-one. Several horizontally arranged crossbars 7 are provided between the front side pillar 1 and the back side pillar 2 on the same side, and between the first adjustable pillar 5 and the corresponding second adjustable pillar 6. At least one carrier plate 81 is provided on the crossbar 7. The spacing between adjacent first adjustable pillars 5 and the spacing between adjacent second adjustable pillars 6 are adjustable.

[0020] This solution is designed so that only the spacing between the first adjustable column 5 and the second adjustable column 6 is adjustable, and the corresponding rack is compatible with animal cages of different widths within a certain range. Example

[0021] Based on Embodiment 1, a supporting ventilation system can be added, including an air intake main pipe 91 located below the outer side of the rear side column 2 and an exhaust main pipe 92 located above the outer side of the rear side column 2. Several ventilation branch pipes 93 are connected in parallel between the air intake main pipe 91 and the exhaust main pipe 92, and air inlet hoses 94 that can connect to animal feeding cages are connected in parallel to the ventilation branch pipes 93. The air intake main pipe 91 is connected to the source of fresh air, and the exhaust main pipe 92 is used to discharge the exhaust gas from the animal feeding cages. Fresh air enters the animal feeding cages and compresses the gas inside the cages to be discharged, thus achieving ventilation. Example

[0022] Based on Embodiment 1 and Embodiment 2, the three-dimensional space of the animal feeding cage within a certain range is adjustable. That is, the longitudinal position of the crossbar 7 on the front side post 1, the back side post 2, the first adjustable post 5 and the second adjustable post 6 connected to it is adjustable, the position of the carrier plate 81 on the crossbar 7 along the length of the crossbar 7 is adjustable, and there are two symmetrically distributed carrier plates 81 on the same crossbar 7. The outer end of the carrier plate 81 has an upwardly flipped limiting stop 811.

[0023] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as one of the adjustable connection methods for the rods, the front side column 1, the back side column 2, the first adjustable column 5, the second adjustable column 6, the crossbar 7, the top frame 3 of the vertical crossbar 7 and the bottom frame 4 of the vertical crossbar 7 all have inwardly flanged U-shaped grooves. The two ends of the crossbar 7 each have a T-shaped connecting piece 82. The upper and lower ends of the front side column 1, the back side column 2, the first adjustable column 5 and the second adjustable column 6 each have triangular connecting pieces 83. The T-shaped connecting piece 82, the triangular connecting piece 83 and the carrier piece 81 each have multiple locking bolts. The locking bolts include a screw, a nut fixed to the outer end of the screw and a nut threaded onto the screw. The nut can slide in the inwardly flanged U-shaped groove while restricting rotation.

[0024] Of course, other existing technologies can also be used to achieve this, such as providing a guide rail for sliding one rod on another rod in mutually perpendicular rods, and locking the connection position after sliding by means of bolts, etc. It can also be a multi-hole positioning type, that is, multiple positioning holes are provided on the relatively fixed part, and positioning blocks that are adapted to the positioning holes are provided on the relatively adjustable part; it can also be a lead screw type, that is, the relatively moving part cooperates with the lead screw, and the rotation of the lead screw can drive the relatively moving part to move along the direction of the lead screw on the relatively fixed part to achieve the adjustment of the relative position. Example

[0025] Based on the needs of movement and transportation, ground wheels can be selected to be installed at the four corners of the bottom frame 4, so that the frame can be easily dragged and moved.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
