Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a climbing frame that can be used for Garcia scoring. Background Art

[0002] The climbing test in the Garcia score provides a method for measuring the grasping and balance coordination ability of rodents' paws to evaluate the animal's neurological deficits. This test has now been used to evaluate neurological function in animal models of various central nervous system diseases, such as stroke and traumatic brain injury.

[0003] However, traditional climbing experiment equipment is not only inconvenient to secure, carry, and store. The difficulty in controlling the scoring angle for each animal leads to varying starting points, resulting in systematic errors in the experiment and scoring process. Common laboratory cage covers are ideal for rodent climbing frames. However, their inability to provide a suspended support makes climbing experiments difficult for animals and objective scoring difficult for researchers. Installing a limiter on the climbing frame allows for a suspended support, eliminating the need for scorers to simultaneously hold the cage cover in place and observe the animal's climbing progress. Furthermore, we divided the wire into evenly spaced areas and color-coded them to initially address subjective assessments. Utility Model Content

[0004] In order to remedy the above shortcomings, the present invention provides a climbing frame that can be used for Garcia scoring, aiming to improve the problem in the prior art that the climbing angle is inconvenient to adjust and thus causes scoring errors.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a climbing frame that can be used for Garcia scoring, comprising a base, a damping shaft is installed on the top of the base, the inner side of the damping shaft is rotatably connected to a rotating frame, the top of the rotating frame is fixedly connected to the climbing frame, and an angle adjustment structure is provided on the other side of the climbing frame, the angle adjustment structure includes a limiting column, both ends of the limiting column are fixedly connected to the inner side of the climbing frame, a movable rod is movably sleeved on the surface of the limiting column, a slot is provided on the top of the base, and the bottom end of the movable rod abuts against the slot.

[0006] As a further description of the above technical solution: a shielding structure is arranged above the climbing frame, and the shielding structure includes a bearing plate, the bottom of the bearing plate is fixedly connected to a limiting bar, the top of the climbing frame is fixedly connected to a side bar, the top of the side bar is provided with a limiting groove, the limiting bar is adapted to the limiting groove, and an entrance is provided at the bottom of the bearing plate.

[0007] As a further description of the above technical solution: a stabilizing structure is respectively provided on the front and back sides of the base, and the stabilizing structure includes an extension plate, the inner wall of the extension plate is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a knob, the bottom end of the threaded rod is fixedly connected to an elliptical pressure plate, and the bottom of the elliptical pressure plate is fixedly connected to a rubber pad. By turning the knob, the threaded rod moves downward on the inner side of the extension plate until the rubber pad contacts the table surface. The provided rubber pad can increase the friction between the elliptical pressure plate and the ground, thereby playing a stabilizing role and avoiding the phenomenon of animals shaking or even tipping over during the experiment due to loose installation.

[0008] As a further description of the above technical solution: an angle dial is fixedly connected to the hinge of the rotating frame, a pointer is rotatably connected to the dial, the back of the pointer is fixedly connected to the inner side of the damping shaft, and the pointer is arranged to rotate following the damping shaft. Since the angle dial is fixed to the front of the rotating frame, the pointer rotates on the angle dial to achieve precise angle hovering.

[0009] As a further description of the above technical solution: there are a total of six card slots, and the card slots are grouped into two groups of three. The two groups of card slots are symmetrically arranged. By rotating the movable rod around the limit column and abutting the bottom end of the movable rod against the card slot, the climbing frame can bear the weight and achieve non-artificial stable support.

[0010] As a further description of the above technical solution: movable wheels are fixedly installed at the four corners of the bottom of the base, the middle fixed sleeve of the limiting column is provided with a rubber sleeve, and the other side of the base is fixedly connected with a handle. The provided movable wheels improve the flexibility of the device, and the provided handle and rubber sleeve can be used to facilitate carrying.

[0011] As a further description of the above technical solution: the supporting plate is hinged with a protective door at the top of the entrance, and a handle is fixedly connected to the top of the protective door. The protective door can be opened conveniently through the provided handle, so that the animal can be placed from the entrance to the climbing frame.

[0012] As a further description of the above technical solution: the limit bar is in a "T" shape, the limit groove is in a "convex" shape, the bottom of the limit bar is in contact with the groove wall of the limit groove and is slidably connected, the limit groove is set to limit the limit bar, and the supporting plate is pulled out by sliding upward, thereby facilitating the installation and disassembly of the supporting plate.

[0013] As a further description of the above technical solution: there are two movable rods, and the two movable rods are symmetrically arranged. The bottom ends of the two movable rods are respectively abutted against the inner walls of the two groups of slots. The symmetrically arranged movable rods have a better load-bearing effect on the climbing frame.

[0014] As a further description of the above technical solution: an observation port is opened on the top of the supporting plate, and glass is fixed on the inner wall of the observation port. The opened observation port facilitates the installation of glass. The purpose of installing the glass is to facilitate the observation of the climbing of rodents. An iron wire is inserted into the inner side of the climbing frame, and the outer part of the iron wire passes through the inner wall of the climbing frame and is inserted. The outer wall of the climbing frame is threadedly connected with a bolt, and the bottom of the bolt abuts the outer wall of the iron wire.

[0015] The utility model has the following beneficial effects:

[0016] 1. This utility model uses an angle adjustment mechanism to adjust the climbing frame at any angle, simulating varying degrees of climbing difficulty. The climbing frame is made of wire, divided into nine zones (top, center, bottom, left, center, and right) using three brightly colored areas. The wire spacing can be set to a fixed distance based on species-specific stride lengths. This device is primarily suitable for evaluating climbing experiments in rats and mice. This improves the objectivity of experimental evaluations.

[0017] 2. In the present invention, different usage modes can be switched according to the different habits of animals through the setting of the shielding structure. When the animal is irritable and unwilling to cooperate, a detachable supporting plate is used to block the top of the wire, leaving only space for the mouse to climb up, so that the mouse can only move on the wire. The activity status of the mouse can be observed through the glass, thereby improving user convenience and meeting the use of various scenarios, meeting the climbing needs and behavioral habits of different animals, and giving full play to the diversity of animal activities.

[0018] 3. In the present invention, the gravity of the base is increased by setting a stable structure, so that the center of gravity of the base is more stable during placement. It is only necessary to turn the knob until the rubber pad contacts the table surface. The provided rubber pad can increase the friction between the elliptical pressure plate and the ground, thereby limiting the movement of the moving wheel and playing a stabilizing role, avoiding the phenomenon of shaking or even tipping over when the animal climbs due to loose installation.
