Description

Technical Field

[0001] The invention relates to the technical field of an elevated cross maze, in particular to an elevated cross maze fixing device. Background Art

[0002] The traditional elevated plus maze features a pair of open and closed arms. Rodents tend to move in the closed arms due to their dark preferences, but also in the open arms out of curiosity and exploratory nature. When faced with novel stimuli, animals experience both an urge to explore and fear, leading to conflicting behaviors between exploration and avoidance, which can cause anxiety. Anti-anxiety medications can significantly increase the number and duration of entries into the open arms. The elevated plus maze is elevated above the ground, similar to standing on a cliff, causing fear and unease in the subjects. The elevated plus maze is widely used in scientific research and computer-assisted instruction across a wide range of disciplines, including drug development / screening / evaluation, pharmacology, toxicology, preventive medicine, neurobiology, animal psychology, and behavioral biology. It is a classic experiment for behavioral research, particularly anxiety and depression.

[0003] When conducting experiments, because the mice in the experiment need to be recorded and their behavior analyzed, the analysis software will be grid-positioned in advance. The traditional elevated plus maze can only be used for experiments on one mouse at a time. When the next mouse is replaced for the experiment, the elevated plus maze will be wiped and the odor will be eliminated by spraying alcohol. During the wiping process, the traditional elevated plus maze is not fixed, causing the position to change, which affects the grid position designed by the behavioral analysis software, resulting in unsatisfactory experimental results, or the grid position must be redesigned, resulting in a waste of time. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an elevated plus maze fixing device to solve the problem pointed out in the background technology that the traditional elevated plus maze is not fixed when wiping after replacing mice, causing the position to change, affecting the grid position designed by the behavioral analysis software, resulting in unsatisfactory experimental results or the need to redesign the grid position, resulting in a waste of time.

[0005] The present invention solves the above technical problems through the following technical means:

[0006] An elevated cross maze fixing device includes an elevated cross maze and a placement frame structure. The elevated cross maze is stably placed on the placement frame structure.

In the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] like Figure 1-8As shown, an embodiment of the present application provides an elevated plus maze fixing device, comprising an elevated plus maze 1 and a placement rack structure, wherein the elevated plus maze 1 is stably placed on the placement rack structure. By placing the elevated plus maze 1 stably and firmly on the placement rack structure, on the one hand, the positions of the elevated plus maze 1 and the placement rack structure are relatively fixed, so that when the elevated plus maze 1 is cleaned after replacing mice, the elevated plus maze 1 will not move relative to the placement rack structure, thereby not affecting the grid position designed by the behavioral analysis software and not affecting the experimental results; on the other hand, the positions of the elevated plus maze 1 and the placement rack structure relative to the ground can be fixed, and the position of the entire device can be further fixed, which facilitates the subsequent cleaning of the elevated plus maze 1 and does not require redesigning the grid position, thereby improving experimental efficiency.

[0038] In this embodiment, the elevated cross maze 1 is a maze structure having a pair of open arms and a pair of closed arms, which is a prior art and will not be described in detail.

[0039] In an optional embodiment, if Figure 1-2 As shown, the placement frame structure includes a placement plate 3, a support base 2, a first fixing mechanism 4, and a second fixing mechanism 5. The placement plate 3 is fixedly connected to the support base 2, fixing the placement plate 3 and the support base 2. The first fixing mechanism 4 is provided on the support base 2 and is used to fix the entire device relative to the ground. The second fixing mechanism 5 is provided at the bottom of the placement plate 3 and is used to fix the position of the elevated plus maze 1 relative to the placement plate 3.

[0040] By cooperating with the placement plate 3, the first fixing mechanism 4 and the second fixing mechanism 5, the position of the elevated plus maze 1 relative to the ground can be fixed, which facilitates the cleaning of the elevated plus maze 1 during the experiment. During the cleaning process, it will not affect the experimental results, nor will it cause additional time waste for the experimenters, which is conducive to improving the efficiency of the experiment.

[0041] In this embodiment, the support seat 2 includes four support rods 21, and the bottom of the four support rods 21 is fixed with support pads 22 by screws. The bottom of the support pads 22 has anti-slip grooves, which are used to increase the relative friction between the support seat 2 and the ground, thereby further improving the stability of the support seat 2.

[0042] In an exemplary embodiment, if Figure 2-4As shown, the placement plate 3 is in a cross shape, and the cross-shaped placement plate 3 is fixedly assembled on the top of the support seat 2 by screwing or spot welding. The placement plate 3 has symmetrical limit plates 31 on the upper and lower sides. There are preferably four limit plates 31, and the four limit plates 31 are symmetrical in pairs on the upper and lower sides of the placement plate 3. And the limit plates 31 are all fixedly assembled on the edge of the placement plate 3 by bolts or spot welding. On the one hand, it is convenient to place the elevated cross maze 1, and on the other hand, it allows the closed arm of the elevated cross maze 1 to be offset against the limit plates 31, which can limit the movement of the elevated cross maze 1 relative to the placement plate 3 to a certain extent. A pad 32 is glued to the inner side of each limiting plate 31, and the pad 32 is preferably a rubber pad. Through the setting of the pad 32, when the elevated cross maze 1 is placed on the placement plate 3, the two sides of the open arm of the elevated cross maze 1 are against the rubber pad, and the closed arm is against the limiting plate 31, which can further limit the movement of the open arm of the elevated cross maze 1 and facilitate the installation of the elevated cross maze 1 on the placement plate 3.

[0043] In an optional embodiment, if Figure 1-3 and Figure 5-6 As shown, the first fixing mechanism 4 includes a fixing base 41, a positioning ring 42, a fastening unit, and a housing 44. The fixing base 41 is fixedly connected to the support base 2. The fixing base 41 has a through slot 412 and a plurality of placement slots 413. The placement slots 413 are connected to the through slot 412. The fastening unit passes through the through slot 412 and abuts against the placement slots 413, which is used to preliminarily assemble the fastening unit on the fixing base 41, thereby assembling the fastening unit in the middle of the inner ring of the support base 2. The outer wall of the fixing base 41 has a positioning slot 414, and the outer wall of the positioning slot 414 is provided with an external thread. The positioning ring 42 is screwed onto the external thread of the positioning slot 414, so that the lower part of the positioning ring 42 is connected to the fastening unit, thereby fastening the fastening unit to the fixing base 41. The shell 44 is fixedly connected to the fixing seat 41 by screws, and the upper part of the fastening unit passes through the middle part of the shell 44, so that the fastening unit will not automatically separate from the fixing seat 41 when in use, and can limit the descending distance of the fastening unit.

[0044] In this embodiment, Figure 2-3 As shown, the fixing base 41 includes a fixing base body and a connecting arm 411. One end of the connecting arm 411 is fixedly screwed or welded to the fixing base body, and the other end is fixedly welded or screwed to the outer wall of the four support rods 21 of the support base 2. In this embodiment, the fixing base body, through slot 412, placement slot 413, and positioning slot 414 are integrally injection molded. The connecting arm 411 is preferably made of a rigid plastic material.

[0045] In this embodiment, Figure 5As shown, the outer wall of the positioning ring 42 is fixedly connected with a connecting ear 421, and the connecting ears 421 are preferably four and evenly distributed, which makes it easier to use the positioning ring 42. In this embodiment, the positioning ring 42 and the connecting ears 421 can be integrally injection molded or welded.

[0046] In an optional embodiment, if Figure 5-7 As shown, the fastening unit includes a fastening base 43, a support block 431, a spring 47, a fastening plug 45, and a pedal 48. The support block 431 is fixedly connected to the fastening base 43. In this embodiment, there are preferably four placement grooves 413 and four support blocks 431. The four support blocks 431 are placed in the four placement grooves 413. When the fastening base 43 is assembled on the fixing base body, the support blocks 431 are placed in the placement grooves 413 and are fastened to the fixing base body via the positioning ring 42, thereby stably assembling the fastening unit on the fixing base 41.

[0047] A fastening plug 45 slides through the middle of the fastening seat 43, allowing it to slide within the fastening seat 43. A retaining ring 46 is fixedly connected to the fastening plug 45 by screws or spot welding. A spring 47 is mounted on the fastening plug 45. One end of the spring 47 is welded to the upper portion of the fastening seat 43, and the other end is welded to the lower portion of the retaining ring 46. This allows the fastening plug 45 to automatically return to its original position after being lowered and not in use, thanks to the spring 47 restoring its deformation. This facilitates the next use of the fastening plug 45. A pedal 48 is connected to the top of the fastening plug 45, allowing the user to press the pedal 48 with their hand or foot, thereby moving the fastening plug 45 downward and securing it to the ground.

[0048] In this embodiment, the fastening base 43 and four support blocks 431 are integrally injection-molded, and the center of the fastening base 43 forms a hollow channel 432. A fastening plug 45 slides through the channel 432 in the center of the fastening base 43, allowing it to slide down the center of the fastening base 43 when pressed by the pedal 48. When not in use, the fastening plug 45 remains stably within the fastening base 43. To ensure that the fastening plug 45 remains better within the fastening base 43 when not in use, an elastic ring is glued into the channel 432 of the fastening base 43, with the outer wall of the fastening plug 45 forming an interference fit with the elastic ring.

[0049] In this embodiment, the diameter of the retaining ring 46 is smaller than the through hole in the middle of the housing 44 , so that the fastening plug 45 and the retaining ring 46 can enter the housing 44 without blocking the movement of the fastening plug 45 .

[0050] In an optional embodiment, if Figure 7As shown, the fastening plug 45 includes a sleeve rod 451, a rubber plug 453, a sealing rod 454, and a knob 455. The sleeve rod 451 slides through the channel 432 in the middle of the fastening seat 43. The rubber plug 453 is bowl-shaped, and the top of the rubber plug 453 is fixedly bonded to the end of the sleeve rod 451. The top of the rubber plug 453 can also be tied with an external steel wire to seal the rubber plug 453 and the sleeve rod 451. The sleeve rod 451 has a cavity 452, which runs through the entire sleeve rod 451. The upper portion of the sealing rod 454 has an external thread, and the upper portion of the cavity 452 has an internal thread. The sealing rod 454 is screwed into the cavity 452 to seal the cavity 452. The knob 455 is fixedly connected to the sealing rod 454 by a screw, which facilitates the use of the sealing rod 454.

[0051] The sealing rod 454 is provided with at least one sealing ring 456 on the lower side of the external thread. In this embodiment, there are preferably three sealing rings 456 for further sealing the cavity 452 .

[0052] When the fastening unit is in use, the pedal 48 is pressed downward by hand or foot to make the fastening plug 45 slide down in the fastening seat 43, so that the rubber plug 453 is in contact with the ground. As the fastening plug 45 moves downward, the rubber plug 453 is deformed, so that the rubber plug 453 forms a negative pressure with the smooth ground, and is stably adsorbed on the ground, firmly adsorbing the fastening unit to the ground, thereby firmly connecting the support seat 2 to the ground, and then firmly connecting the entire device to the ground, so that the elevated cross maze 1 will not move when cleaning, thereby not affecting the experiment.

[0053] As the fastening plug 45 slides downward, the pedal 48 abuts against the outer wall of the housing 44, limiting the downward distance of the fastening plug 45, thereby preventing excessive deformation of the rubber plug 453 and preventing the rubber plug 453 from being firmly attached to the ground. To better ensure that the rubber plug 453 is firmly attached to the ground, some water can be sprinkled inside the rubber plug 453 or on the ground to form a toilet plug shape, so that the entire device is firmly attached to the ground.

[0054] When the plug 453 needs to be separated from the ground, the knob 455 is turned to partially separate the sealing rod 454 from the cavity 452, so that the inside of the plug 453 is connected to the outside world, thereby facilitating the separation of the plug 453 from the ground. The spring 47 then restores the deformation and the plug 453 is separated from the ground, thereby facilitating the movement of the entire placement rack structure.

[0055] In some other optional embodiments, a small negative pressure machine and a negative pressure suction cup can be used to replace the rubber plug 453 and the sealing rod 454. When a small negative pressure machine and a negative pressure suction cup are used, the negative pressure machine is fixedly installed at the bottom of the sleeve rod 451 by screws, and the negative pressure suction cup is fixedly assembled at the output end of the negative pressure machine. During use, when the user's hand or foot squeezes the sleeve rod 451 downward, the negative pressure machine and the negative pressure suction cup descend. When the pedal 48 and the housing 44 are against each other, the negative pressure suction cup is in contact with the ground. At this time, the negative pressure machine is started so that the negative pressure suction cup is firmly adsorbed on the ground, fixing the relative position of the entire device and the ground, thereby facilitating the subsequent cleaning of the elevated cross maze 1. In this embodiment, the negative pressure machine is a noiseless negative pressure machine to avoid affecting the experimental process.

[0056] In an optional embodiment, if Figure 2 and Figure 8 As shown, the second fixing mechanism 5 includes at least one first fixing component and a second fixing component. In this embodiment, the first fixing component and the second fixing component are preferably both one, and the first fixing component and the second fixing component are symmetrically arranged on both sides of the placement plate 3. Through the mutual cooperation of the first fixing component and the second fixing component, the elevated cross maze 1 can be further stably mounted on the placement plate 3, and when the elevated cross maze 1 is cleaned, it will not cause relative movement between the elevated cross maze 1 and the placement plate 3. In this embodiment, the first fixing component and the second fixing component have the same structure, which is convenient for operation and saves use costs.

[0057] In an exemplary embodiment, if Figure 8 As shown, the first fixing assembly is used as an example for description. The first fixing assembly includes a mounting post 51, a connecting post 52, a connecting bracket 53, an arc-shaped arm 54, and a fastener. The mounting post 51 is fixedly connected to the bottom of the placement plate 3. In this embodiment, the mounting post 51 is fixedly connected to the bottom of the placement plate 3 by bolts or welding.

[0058] The connecting column 52 is fixedly connected to the mounting column 51, and the connecting frame 53 is rotatably assembled on both sides of the connecting column 52. When the connecting column 52 is assembled, the connecting column 52 passes through both ends of the connecting frame 53 and the mounting column 51. After assembly, the connecting column 52 is fixedly installed on the mounting column 51 with bolts, so that the connecting frame 53 can rotate on the mounting column 51. One end of the arcuate arm 54 is fixedly welded to the middle of the connecting frame 53, and a fastener is connected to the free end of the arcuate arm 54. Through the use of the first fixing assembly, the closed arm of the elevated cross maze 1 can be offset, and the closed arm can be matched with the limit plate 31 to secure the elevated cross maze 1 firmly to the placement plate 3. Moreover, by using the first fixing assembly and the second fixing assembly together, the elevated cross maze 1 can be more firmly secured to the placement plate 3.

[0059] The first fixing assembly and the second fixing assembly can be used alone or together. When the first fixing assembly and the second fixing assembly are not in use, the first fixing assembly and the second fixing assembly can be rotated and hung upside down below the placement plate 3 without causing additional impact.

[0060] In this embodiment, Figure 8 As shown, the fastener includes a threaded rod 55, a handle 56, a transfer rod 57 and a fastening plate 58. The threaded rod 55 is screwed to the free end of the arc-shaped arm 54, the handle 56 is fixedly connected to the left end of the threaded rod 55 by a screw, and the transfer rod 57 is fixedly welded to the right end of the threaded rod 55. The fastening plate 58 is connected to the free end of the transfer rod 57, and a bearing 571 is provided between the fastening plate 58 and the transfer rod 57. By rotating the handle 56, the fastening plate 58 can be made to abut against the closed arm of the elevated cross maze 1. During the movement of the threaded rod 55, the fastening plate 58 will not rotate, thereby increasing the contact force between the closed arm of the elevated cross maze 1 and the placement plate 3, further firmly fixing the elevated cross maze 1 on the placement plate 3. At the same time, the fastener is also easy to unlock, thereby facilitating the replacement of other cross mazes.

[0061] In this embodiment, a buffer pad 581 is glued to one side of the fastening plate 58 to prevent the fastening plate 58 from damaging the closed arm of the elevated plus maze 1 when fixing the elevated plus maze 1 .

[0062] The above describes in detail the elevated plus maze fixture provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will appreciate that various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
