Description

Technical Field

[0001] The utility model belongs to the technical field of animal specimen support, and in particular relates to a bracket for an animal specimen prosthesis. Background Art

[0002] Animal specimens are often used in teaching, scientific research, exhibitions, popular science and other occasions. Their types mainly include immersed specimens, skinned specimens, bone specimens, dried specimens, glass specimens and the like. Among them, skinned specimens are to peel off the animal skin together with the hair, feathers, scales and other derivatives on it, and then fix the skin on the prosthesis to make a specimen. In the process of making the specimen prosthesis, it is required that the prosthesis can be reliably fixed and the prosthesis itself cannot be damaged. The usual practice is that each time a specimen prosthesis is made, a temporary bracket needs to be customized with wood according to the shape of the animal specimen, and the support point of the prosthesis is fixed on the temporary bracket so that the prosthesis can be reliably fixed and the prosthesis can be finely carved. Because the shapes of animal specimens are different and the overall sizes are different, the support points of each specimen prosthesis are different, so the temporary bracket cannot be reused, resulting in waste of resources and increased production costs.

[0003] For example, a Chinese patent (authorization announcement number: CN 216623572 U) discloses a special bracket for making animal specimen prostheses, including a ground-mounted base assembly, a support assembly vertically supported below the support point of the prosthesis, and the support assembly is fixedly connected to the base assembly. By setting the support assembly to include a first connecting member, a support rod and a locking ejector pin, the height of the top of the support rod can be adjusted as needed to adapt to the support points of animal specimen prostheses of different heights, and the adjustment is very convenient. By setting a connecting through hole at the bottom end of the first connecting member to cooperate with the longitudinal connecting rod or transverse connecting rod in the base assembly, the support assembly can be positioned and set at any position of the base assembly. The relative position of the transverse connecting rod and the longitudinal connecting rod can be adjusted at any time as needed to adjust the position of the support assembly, thereby adapting to the support needs of different animal specimen prostheses.

[0004] However, in the above scheme, when replacing the animal specimen prosthesis, if the supporting point of the animal specimen prosthesis changes greatly, interference occurs during the movement of the supporting assembly on the base assembly, and the support change of different animal specimen prostheses is limited. Utility Model Content

[0005] The purpose of the utility model is to provide a bracket for animal specimen prosthesis, which can meet the needs of supporting animal specimen prostheses of different body shapes and models in a wider range.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0012] It is further defined that the base is provided with a base stepped hole, the rotating shaft is a stepped shaft, and the rotating shaft is located in the base stepped hole. The base stepped hole cooperates with the rotating shaft to limit the up and down movement of the rotating shaft.

[0013] It is further defined that the base is provided with a base notch and a base threaded hole, a screw is provided in the base threaded hole, and the screw can lock the rotating shaft. The rotation and locking of the rotating shaft can be achieved through the cooperation of the base notch and the screw passing through the base threaded hole.

[0014] It is further defined that the screw is a butterfly screw. The butterfly screw is convenient for hand-carrying operation and improves work efficiency.

[0015] It is further defined that the end of the connecting rod away from the base is fixedly connected with a cushion block.

[0016] It is further defined that the number of the connecting rods is multiple, and the number of the supporting rods is not less than the number of the connecting rods. The number of connecting rods and supporting rods is increased or decreased according to the number of supporting points.

[0017] The utility model adopting the above technical solution has the following advantages:

[0018] 1. The connecting rod is driven to rotate by the rotation of the rotating shaft on the base. The supporting rod is a lockable telescopic rod. The supporting rod is slidably connected to the connecting rod and can be locked. It can adapt to the support needs of animal specimen prostheses of different body shapes and shapes in a wider range.

[0019] 2. The notched external threaded pipe and the locking nut can be used to lock and unlock the connection between the support rod and the connecting rod.
