Description

Technical Field

[0001] This invention relates to the field of marking pens for marking the tails of laboratory mice, specifically a marking pen for marking the tails of laboratory mice. Background Technology

[0002] The development of medical experiments plays a vital role in the progress of medicine. In medical experiments, mice are often used as experimental subjects. When conducting experiments, multiple groups of mice are set up for comparison. In order to distinguish the mice, they are usually marked with a marker pen on their tails.

[0003] In the existing technology, the most common marking pens are thick-barreled with a pointed tip. Lines are drawn using the pointed tip. When using them, one hand needs to hold the mouse by the tail while the other hand draws the line little by little. This is inefficient and inconvenient. If the mouse is active, it is even more difficult to complete the line drawing operation.

[0004] With the development of technology, some marking pens have been designed with semi-circular tips, which makes it easier to draw lines compared to pointed markers. However, in the process of drawing lines, it is still necessary to manually circle around the tail of the mouse to draw the lines, which reduces the efficiency of marking lines on the mouse tail and is somewhat inconvenient to use. Therefore, a marking pen for marking lines on the tail of laboratory mice is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a marking pen for marking the tail of laboratory mice, which has the advantages of being convenient to use and highly efficient, thus solving the problems of inconvenience and low efficiency in the use of existing marking pens.

[0008] Furthermore, the ink assembly includes an ink reservoir fixed to the top surface of an outer opening ring. An ink filling tube is fixedly connected to the top surface of the ink reservoir. Multiple mounting holes are provided on the bottom surface of the ink reservoir. Ball bearings are rotatably connected to the mounting holes. A partition is fixed between the inner walls of the ink reservoir. A circular tube with its bottom end penetrating the partition is fixed to the inner top wall of the ink reservoir. A rotating rod with its bottom end extending into the circular tube is rotatably connected to the top surface of the ink reservoir. A rubber block is fixed to the bottom end of the rotating rod. A circular groove is provided on the bottom surface of the rubber block. Rectangular holes are provided on the outer peripheral wall of the circular tube and the outer peripheral wall of the rubber block.

[0009] Furthermore, both the outer open ring and the inner open ring are circular rings with notches, and they are located on the same central axis. The guide groove and the guide plate are both arc-shaped, and they are located on the same central axis.

[0010] Furthermore, steel balls are rolled on both the top and bottom surfaces of the guide plate, and an arc-shaped groove is opened inside the outer opening ring to communicate with the guide groove and to allow the steel balls to roll.

[0011] Furthermore, an anti-slip sleeve is fitted on the outer peripheral wall of the handle, and a controller is fixed on the outer peripheral wall of the handle, with both the first motor and the second motor electrically connected to the controller.

[0012] Furthermore, the rack is arc-shaped, the gear is disposed in the guide groove, and the end of the inner open ring is provided with a through hole for the arc-shaped rod to pass through and slide in connection with it.

[0013] Furthermore, the arc-shaped groove is used to allow the slider to make arc-shaped movements around its central axis inside the inner open ring, and the spring is fitted on the outer peripheral wall of the pull wire, and the spring is disposed between the slider and the annular plate.

[0014] Furthermore, the ink reservoir is a semi-circular reservoir, the top end of the ink filling tube is threaded with a sealing cap, and the bottom surface of the ball is in contact with the open sponge block.

[0015] Furthermore, the partition divides the ink reservoir into upper and lower parts, a handle is fixed to the top of the rotating rod, and the outer peripheral wall of the rubber block contacts the inner peripheral wall of the circular tube.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This laboratory mouse tail marking pen, when in use, uses a control component to easily control the open sponge block to wrap around the mouse's tail. Then, the control component controls the inner open ring to rotate inside the outer open ring. The inner open ring drives the open sponge block to rotate, creating friction with the mouse's tail, thereby applying ink to the mouse's tail to complete the marking. The control component enables automatic circular marking, making the entire process simpler and faster, greatly improving the efficiency and convenience of marking, making it more practical and easier to promote and use.

[0018] 2. The marking pen for marking the tail of this experimental mouse has an ink assembly on the top surface of the outer open ring. The ink assembly facilitates ink storage and allows the ink to soak into the open sponge block during use, so that the open sponge block can continuously obtain ink for marking. At the same time, the ink assembly has an adjustable function, which can change the ink output and avoid the inconvenience caused by ink saturation and dripping from the open sponge block, thus improving its practicality.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-3 This embodiment of a marking pen for marking the tail of a laboratory mouse includes an outer open ring 1, an inner open ring 2 slidably connected to the inner side of the outer open ring 1, a guide plate 3 fixed to the outer peripheral wall of the inner open ring 2, a guide groove 4 for sliding connection of the guide plate 3 on the inner peripheral wall of the outer open ring 1, an open sponge block 5 fixed to the inner side of the inner open ring 2, a handle 6 fixed to the outer peripheral wall of the outer open ring 1, and a control component 7 on the outer open ring 1. In use, the control component 7 facilitates the control of the open sponge block 5 to wrap around the tail of the laboratory mouse, and then the control component 7 controls the inner open ring 2 to rotate inside the outer open ring 1, thereby causing the inner open ring 2 to rotate and interact with the open sponge block 5 around the tail of the laboratory mouse. The friction generated by the ink allows ink to be applied to the tail of the laboratory mouse to complete the drawing. The automatic circular drawing is achieved through the control component 7, making the entire process simpler and faster, greatly improving the efficiency and convenience of drawing lines, making it more practical and easier to promote and use. An ink component 8 is provided on the top surface of the outer open ring 1. The ink component 8 facilitates the storage of ink and allows the ink to soak into the open sponge block 5 during use, so that the open sponge block 5 can continuously obtain ink for drawing lines. At the same time, the ink component 8 has an adjustable function, which can change the ink output to avoid the ink from saturating and dripping from the open sponge block 5, which would cause inconvenience, thus improving practicality.

[0029] Both the outer open ring 1 and the inner open ring 2 are circular rings with notches, and they are located on the same central axis. The guide groove 4 and the guide plate 3 are both arc-shaped and located on the same central axis. Steel balls are rolled on the top and bottom surfaces of the guide plate 3. The outer open ring 1 has an arc-shaped rolling groove that communicates with the guide groove 4 and is used for rolling the steel balls. This structure makes it easy for the inner open ring 2 to drive the open sponge block 5 to rotate and thus complete the marking operation.

[0030] Please see Figure 4-5 The control component 7 includes a first motor 701 fixed to the bottom surface of the outer open ring 1. A gear 702 is fixed to the top of the first motor 701. A rack 703 that meshes with the gear 702 is fixed to the side of the guide plate 3 away from the inner open ring 2. In use, one hand lifts the tail of the experimental mouse, and the other hand holds the handle 6. The experimental mouse tail is inserted into the opening of the outer open ring 1 and into the opening of the open sponge block 5 and makes contact with it, so that the experimental mouse tail is roughly on the central axis of the inner open ring 2. Then the first motor 701 is started. The first motor 701 drives the gear 702 to rotate. The gear 702 drives the guide plate 3 to slide in the guide groove 4 through the rack 703, further driving the inner open ring 2 to rotate inside the outer open ring 1. The inner open ring 2 drives the open sponge block 5 to rotate around the experimental mouse tail. Then, the ink is painted on the experimental mouse tail by the friction between the open sponge block 5 and the experimental mouse tail to complete the marking.

[0031] Please see Figure 4-5 An arc-shaped groove 704 is formed inside the inner open ring 2. A slider 705 is slidably connected inside the arc-shaped groove 704. An annular plate 706 is fixed inside the arc-shaped groove 704. A second motor 707 is fixed to the side of the annular plate 706 away from the slider 705. A threaded wheel 708 is fixed to the output shaft of the second motor 707. A pull wire 709, one end of which is fixed to the slider 705, is fixed to the outer peripheral wall of the threaded wheel 708. An arc-shaped rod 710 extending to the opening of the inner open ring 2 is fixed to the side of the slider 705 away from the annular plate 706. The end of the arc-shaped rod 710 away from the slider 705 is fixed to the open sponge block 5. A spring 711 is fixed to one side of the arc-shaped rod 710. Before the inner opening ring 2 is rotated, the second motor 707 can be started. The second motor 707 drives the thread wheel 708 to rotate, which releases the pull line 709. At this time, the spring 711 pushes the slider 705 to slide in the arc-shaped groove 704. The slider 705 pushes the arc-shaped rod 710 out of the arc-shaped groove 704 and drives the opening of the opening sponge block 5 to close. This makes it easier for the opening sponge block 5 to wrap the tail of the experimental mouse and improve the drawing effect. After the drawing is completed, reversing the second motor 707 will cause the arc-shaped rod 710 to retract, making it convenient to put in the next experimental mouse for drawing.

[0032] In this embodiment, an anti-slip sleeve is fitted on the outer peripheral wall of the handle 6, and a controller is fixed on the outer peripheral wall of the handle 6. The first motor 701 and the second motor 707 are both electrically connected to the controller. It should be noted that the controller should have two control buttons for individually controlling the first motor 701 and the second motor 707. The control circuit of the controller can be implemented by simple programming by those skilled in the art. Since both the outer open ring 1 and the inner open ring 2 are open, the inner open ring 2 does not need to rotate a full circle. The controller needs to control the first motor 701 to rotate forward for a certain period of time and then drive it to rotate in reverse. This effect can be achieved by a limit switch or other structure. The limit switch and the power supply are also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so this application will not explain the control method and circuit connection in detail.

[0033] The rack 703 is arc-shaped, the gear 702 is set in the guide groove 4, the end of the inner open ring 2 is provided with a through hole for the arc-shaped rod 710 to pass through and slide with it, the arc groove 704 is used for the slider 705 to make arc-shaped movement around its central axis inside the inner open ring 2, the spring 711 is fitted on the outer peripheral wall of the pull wire 709, and the spring 711 is set between the slider 705 and the annular plate 706.

[0034] Please see Figure 6-7 In this embodiment, the ink assembly 8 includes an ink tank 801 fixed to the top surface of the outer opening ring 1. The top surface of the ink tank 801 is fixedly connected to an ink filling tube 802. The bottom surface of the ink tank 801 is provided with multiple mounting holes 803. A ball bearing 804 is rotatably connected inside the mounting holes 803. When marking lines, ink is added to the ink tank 801 through the ink filling tube 802. The ink inside the ink tank 801 can flow through the mounting holes 803 and the ball bearing 804 to the open sponge block 5 so that the open sponge block 5 can leave marking marks when rubbing the tail of the experimental mouse.

[0035] Please see Figure 6-7A partition 805 is fixed between the inner walls of the ink tank 801. A circular tube 806 with its bottom end penetrating through the partition 805 is fixed to the inner top wall of the ink tank 801. A rotating rod 807 with its bottom end extending into the circular tube 806 is rotatably connected to the top surface of the ink tank 801. A rubber block 808 is fixed to the bottom end of the rotating rod 807. A circular groove 809 is opened on the bottom surface of the rubber block 808. Rectangular holes 810 are opened on the outer peripheral walls of the circular tube 806 and the outer peripheral walls of the rubber block 808. The ink tank 801 is a semi-circular tank. A sealing cap is threaded to the top end of the ink filling tube 802. The bottom surface of the ball bearing 804 is in contact with the open sponge block 5. The partition 805 divides the ink tank 801 into upper and lower parts. A handle is fixed to the top end of the rotating rod 807. The outer peripheral wall of the rubber block 808 is in contact with the inner peripheral wall of the circular tube 806. The partition 805 divides the ink tank 801 into upper and lower parts. The system consists of two parts. When ink flows out of the ink tank 801, it must first flow through the circular tube 806 to the bottom of the partition 805, and then flow out through the mounting hole 803. When the open sponge block 5 absorbs less ink and the drawn line is not clear enough, the rotating rod 807 is rotated. The rotating rod 807 drives the rubber block 808 to rotate inside the circular tube 806, thereby increasing the overlap between the rectangular holes 810 on the rubber block 808 and the rectangular holes 810 on the outer wall of the circular tube 806. At this time, the diameter of the orifice for ink flow is large, increasing the ink output efficiency of the mounting hole 803. When the open sponge block 5 absorbs more ink, the rotating rod 807 is rotated, thereby reducing the overlap between the rectangular holes 810 on the rubber block 808 and the rectangular holes 810 on the outer wall of the circular tube 806. The diameter of the orifice for ink flow is small, and the efficiency of the ink flowing downward inside the ink tank 801 is reduced, thus achieving the effect of controlling the amount of ink output.

[0036] The working principle of the above embodiments is as follows:

[0037] (1) In use, lift the tail of the experimental mouse with one hand and hold the handle 6 with the other hand. Insert the tail of the experimental mouse into the opening of the outer opening ring 1, and make the tail enter the opening of the opening sponge block 5 and make it contact the tail. Make the tail of the experimental mouse roughly on the central axis of the inner opening ring 2. Then start the first motor 701. The first motor 701 drives the gear 702 to rotate. The gear 702 drives the guide plate 3 to slide in the guide groove 4 through the rack 703, which further drives the inner opening ring 2 to rotate inside the outer opening ring 1. This causes the inner opening ring 2 to drive the opening sponge block 5 to rotate around the tail of the experimental mouse, and then the tail of the experimental mouse is inserted through the opening sponge block 5. The friction between the tails applies ink to the mouse's tail to create a line mark. Before the inner opening ring 2 rotates, the second motor 707 can be activated. The second motor 707 drives the thread wheel 708 to rotate, releasing the pull line 709. At this time, the spring 711 pushes the slider 705 to slide within the arc groove 704. The slider 705 pushes the arc rod 710 out of the arc groove 704 and causes the opening of the opening sponge block 5 to close. This allows the opening sponge block 5 to better wrap around the mouse's tail, improving the line marking effect. After the line is drawn, reversing the second motor 707 will cause the arc rod 710 to retract, making it easier to insert the next mouse for line marking.

[0038] (2) When marking lines, ink is added to the ink tank 801 through the ink filling tube 802. The ink inside the ink tank 801 can flow through the mounting hole 803 and the ball bearing 804 to the open sponge block 5 so that the open sponge block 5 can leave a marking mark when rubbing the tail of the experimental mouse. The partition 805 divides the ink tank 801 into upper and lower parts. When the ink flows out of the ink tank 801, it must first flow through the circular tube 806 to the bottom of the partition 805, and then flow out through the mounting hole 803. When the open sponge block 5 absorbs less ink and the marked line is not clear enough, rotate the rotating rod 807. 07 drives the rubber block 808 to rotate inside the circular tube 806, thereby increasing the overlap between the rectangular holes 810 on the rubber block 808 and the rectangular holes 810 on the outer wall of the circular tube 806. At this time, the diameter of the orifice for ink flow is large, increasing the ink output efficiency of the mounting hole 803. When the open sponge block 5 absorbs a lot of ink, the rotating rod 807 is rotated, reducing the overlap between the rectangular holes 810 on the rubber block 808 and the rectangular holes 810 on the outer wall of the circular tube 806. This reduces the diameter of the orifice for ink flow, thus lowering the efficiency of the downward flow of ink inside the ink tank 801, thereby achieving the effect of controlling the amount of ink output.
