Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical industry, and in particular relates to a bird testing and fixing device. Background Technology
[0002] During acute toxicity tests on birds in the laboratory, birds typically resist violently. Maintaining them still allows for better application of the toxic substance. Existing bird restraint devices usually involve directly binding the bird's body, which allows the bird to easily break free, making restraint difficult and potentially causing injury during the struggle. Furthermore, this method is only effective for birds of a certain size, and is ineffective for relatively large or small birds. Summary of the Invention
[0003] In view of this, the present invention aims to overcome the defects in the prior art and propose a bird testing fixation device.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A bird testing restraint device includes an adjusting sleeve and a limiting sleeve rod, wherein one end of the adjusting sleeve is fitted onto the outside of the limiting sleeve rod and is movably connected to the limiting sleeve rod;
[0006] Both the adjusting sleeve and the limiting sleeve rod are provided with a fixing seat. The fixing seat of the adjusting sleeve is provided with a front limiting chamber, and the fixing seat of the limiting sleeve rod is provided with a rear limiting chamber. The front limiting chamber and the rear limiting chamber have the same structure and are arranged opposite to each other.
[0007] Furthermore, the limiting sleeve is internally equipped with a limiting component. One end of the limiting component is connected to the inner wall of the limiting sleeve, and the other end has a limiting block on its outer side. The limiting sleeve has a limiting groove, and the adjusting sleeve has several adjusting grooves. The limiting block passes sequentially through the limiting groove and the adjusting groove. After the position between the front and rear limiting chambers is adjusted, it is fixed by the limiting block of the limiting component, making it suitable for birds of different sizes.
[0008] Furthermore, the top of the limiting block has an arc-shaped structure. This facilitates the limiting block disengaging from the adjusting groove when the adjusting sleeve is pushed.
[0009] Furthermore, the inner diameter of the adjusting groove is smaller than the inner diameter of the limiting groove. When the adjusting sleeve is pulled, the limiting block can easily disengage from the adjusting groove, improving the operability of the device.
[0010] Furthermore, the limiting component has a semi-elliptical cross-section and is made of plastic. When the adjusting sleeve is pulled, the limiting block disengages from the adjusting groove, is compressed, and moves inside the adjusting sleeve. Simultaneously, due to its semi-elliptical structure, the limiting component can adjust its minor axis length according to the applied force without causing damage.
[0011] Furthermore, the front limiting compartment includes a first limiting part and a second limiting part, which have the same structure. One end of the first limiting part is movably connected to the second limiting part via a connecting hinge, and the other end of the first limiting part is connected to the second limiting part via a snap-fit. The bird's body is positioned between the front limiting compartment and the rear limiting compartment.
[0012] Furthermore, both the front and rear limiting chambers are provided with protrusion holes on one side. The protrusion hole of the front limiting chamber faces the adjusting sleeve, and the protrusion hole of the rear limiting chamber faces the limiting sleeve rod. The bird's head can be placed in either protrusion hole as needed. If the bird's tail is long, the tail can be placed in the protrusion hole to prevent the bird from being squeezed or injured.
[0013] Furthermore, the adjusting sleeve is provided with several support frames, and the bottom of each support frame is provided with a suction cup. The fixing device can be placed on a table using the support frames and fixed to the table using the suction cups, or it can be moved to other designated locations and then fixed, making it convenient and stable to use.
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] The bird testing and fixing device of this utility model fixes the relative position of the limiting sleeve and the adjusting sleeve by setting a limiting element in the limiting sleeve. Adjusting grooves that cooperate with the limiting block are set at different positions on the adjusting sleeve, so as to adjust the position between the limiting sleeve and the adjusting sleeve, thereby fixing birds of different sizes.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] like Figure 1-6 As shown, a bird testing restraint device includes an adjusting sleeve 1 and a limiting sleeve 2. One end of the adjusting sleeve 1 is fitted onto the outside of the limiting sleeve 2 and is movably connected to the limiting sleeve 2. Both the adjusting sleeve 1 and the limiting sleeve 2 are provided with a fixing seat 5. The fixing seat 5 of the adjusting sleeve 1 is provided with a front limiting chamber 3, and the fixing seat 5 of the limiting sleeve 2 is provided with a rear limiting chamber 4. The front limiting chamber 3 and the rear limiting chamber 4 have the same structure and are arranged opposite to each other.
[0030] The limiting sleeve 2 has a limiting member 21 inside. One end of the limiting member 21 is connected to the inner wall of the limiting sleeve 2, and the other end has a limiting block 22 on its outer side. The limiting sleeve 2 has a limiting groove 23, and the adjusting sleeve 1 has several adjusting grooves 11. The limiting block 22 passes through the limiting groove 23 and the adjusting groove 11 in sequence. After the position between the front limiting chamber 3 and the rear limiting chamber 4 is adjusted, it is fixed by the limiting block 22 of the limiting member 21, which is suitable for birds of different sizes. The top of the limiting block 21 has an arc-shaped structure. When the adjusting sleeve 1 is pushed, it is easy for the limiting block 22 to disengage from the adjusting groove 11. The inner diameter of the adjusting groove 11 is smaller than the inner diameter of the limiting groove 23. When the adjusting sleeve 1 is pulled, it is easy for the limiting block 22 to disengage from the adjusting groove 11, which improves the operability of the device.
[0031] The limiting member 21 has a semi-elliptical cross-section and is made of plastic. When the adjusting sleeve 1 is pulled, the limiting block 22 disengages from the adjusting groove 11, is compressed, and moves inside the adjusting sleeve 1. At the same time, due to its semi-elliptical structure, the limiting member 21 can adjust its minor axis length according to the force applied without causing damage.
[0032] The front limiting chamber 3 includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 and the second limiting part 32 have the same structure. One end of the first limiting part 31 is movably connected to the second limiting part 32 via a connecting hinge 35, and the other end of the first limiting part 31 is connected to the second limiting part 32 via a buckle 34. The bird's body is positioned between the front limiting chamber 3 and the rear limiting chamber 4. Both the front limiting chamber 3 and the rear limiting chamber 4 have protrusion holes 33 on one side. The protrusion hole 33 of the front limiting chamber 3 faces the adjusting sleeve 1, and the protrusion hole 33 of the rear limiting chamber 4 faces the limiting sleeve rod 2. The bird's head can be placed in any of the protrusion holes 33 as needed. For example, if the bird's tail is long, the tail can be placed in the protrusion hole 33 to prevent the bird from being squeezed and injured. The adjusting sleeve 1 is provided with several support frames 6, and the bottom of each support frame 6 is provided with a suction cup 7. The fixing device can be placed on the table via the support frame 6 and fixed on the table via the suction cup 7. It can also be moved to other designated locations and then fixed. It is convenient and stable to use.
[0033] Before use, open the latches 34 of the front limiting chamber 3 and the rear limiting chamber 4. The opening angle of the first limiting part 31 and the second limiting part 32 can be adjusted by the connecting hinge 35. Stretch the adjusting sleeve 1 and the limiting sleeve rod 2. When the adjusting sleeve 1 is pulled, the limiting block 22 comes out of the adjusting groove 11. The relative position between the adjusting sleeve 1 and the limiting sleeve rod 2 can be adjusted. When the distance between the front limiting chamber 3 and the rear limiting chamber 4 is sufficient, place the bird between the first limiting part 31 and the second limiting part 32, with its head protruding from the protrusion hole 33. Then close the latches 34. According to the size of the bird, push the adjusting sleeve 1 to the appropriate position. At this time, the limiting block 22 is placed in the appropriate adjusting groove 11, which serves to fix the bird.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
