Description

Technical Field

[0001] The utility model provides a quickly spliced ​​hollow copper ball, belonging to the technical field of copper balls. Background Art

[0002] A copper ball is a spherical object, usually made of copper. They can have different diameters and surface treatments to meet different needs and uses. Copper balls are widely used in engineering, scientific experiments, and art. Copper is an excellent conductive material and can be used as a component of conductive materials and as a heat conduction medium; in scientific experiments, copper balls may be used as experimental equipment or experimental materials, such as for simulating physical processes or conducting laboratory tests. Generally speaking, setting a filler ball inside a hollow copper ball can change the performance of the hollow copper ball, such as increasing its mass, improving its thermal conductivity, and adjusting its buoyancy. The choice of filler ball depends on the specific application scenario and the required performance parameters.

[0003] In order to facilitate the selection of filling balls, hollow copper balls are often composed of two hemispheres. A suitable filling ball is selected and placed between the two hemispheres, and then the hemispheres are fixed and spliced ​​to form a complete sphere. The splicing of the two hemispheres often uses connection methods such as threads, which is slow and easy to leave fixed structures on the surface of the copper sphere, affecting the smoothness and aesthetics of the sphere. At the same time, if the filling ball is directly placed in the copper ball, it is easy to roll relative to the copper ball, affecting the use effect of the copper ball. Therefore, a fixed structure is used to fix the filling ball to the copper ball, which also increases the operation steps and affects the splicing speed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the splicing speed of the hollow copper ball is slow after selecting suitable filling balls, and the smoothness and aesthetics of the ball are easily affected.

[0005] In order to solve the above problems, the utility model proposes a technical solution: a quickly spliced ​​hollow copper ball, comprising a left hemisphere and a right hemisphere; the left hemisphere and the right hemisphere are both hollow structures, and filling balls are placed in the hollow structures of the two; a connecting groove is provided on the inner side of the left hemisphere, and a connecting block inserted into the connecting groove is fixedly arranged on the inner side of the right hemisphere; a plug hole is provided in the connecting block, and a plug rod inserted into the plug hole is slidably arranged in the connecting groove; an inclined surface is provided on the connecting block, and a ball is rolled on the end of the plug rod; a limiting hole is provided on the filling ball, and a limiting rod inserted into the limiting hole is fixedly connected to the left and right hemispheres.

[0006] As an improvement, a spring hole is opened in the left hemisphere, and the insertion rod is located in the spring hole; a compression spring sleeved on the insertion rod is arranged in the spring hole, and a compression plate fixedly sleeved on the insertion rod is arranged in the spring hole.

[0007] As an improvement, the compression spring has a reserved compression amount during installation.

[0008] As an improvement, a guide hole connected to the spring hole is opened in the left hemisphere, and the end of the insertion rod is located in the guide hole.

[0009] As an improvement, a sealing groove is provided inside the left hemisphere, and a sealing block inserted into the sealing groove is fixedly connected to the inside of the right hemisphere.

[0010] As an improvement, elastic pads are provided inside the left hemisphere and the right hemisphere, and the elastic pads exert pressure on the filling ball.

[0011] Beneficial effects of the utility model:

[0012] A connecting block inserted into the connecting groove is fixedly arranged on the inside of the right hemisphere, and a plug rod inserted into the socket is slidably arranged in the connecting groove; the left hemisphere and the right hemisphere are connected through the connecting block and the connecting groove, and are connected by means of the plug rod and the socket, which can quickly complete the splicing and fixing of the left and right hemispheres. At the same time, the left and right hemispheres are quickly connected to the filling ball by means of the connection method of the limiting rod and the limiting hole, which can greatly improve the splicing speed of the two hemispheres while ensuring that the filling ball and the copper ball are relatively fixed. After the two hemispheres are spliced ​​together, there is no other structure except the splicing gap, thereby ensuring the smoothness and beauty of the two hemispheres.

The compression spring 12 is provided with a compression amount when installed.

[0024] The compression spring 12 is provided with a reserved compression amount during installation so as to continuously exert pressure on the compression plate 11 , thereby increasing the stability of the fixing of the insertion rod 14 to the connection block 7 .

[0025] A guide hole 13 communicating with the spring hole 15 is provided in the left hemisphere 1 , and the end of the insertion rod 14 is located in the guide hole 13 . The setting of the guide hole 13 can guide the sliding of the insertion rod 14 .

[0026] A sealing groove 3 is provided inside the left hemisphere 1 , and a sealing block 6 inserted into the sealing groove 3 is fixedly connected inside the right hemisphere 2 , so as to increase the sealing performance after the left hemisphere 1 and the right hemisphere 2 are spliced.

[0028] Principle of the utility model

[0029] Before the hollow copper balls are joined, the two hemispheres and the filling ball 16 are as follows Figure 2 , 3 6. Place the filling ball 16 between the left hemisphere 1 and the right hemisphere 2, aligning the limiting hole 18 on the filling ball 16 with the limiting rod 9; splice the two hemispheres, insert the limiting rod 9 into the limiting hole 18 to fix the filling ball 16 and the copper ball, and insert the connecting block 7 into the connecting groove 4. Figure 4 , 5 As shown, during the process of inserting the connection block 7 into the connection groove 4, the inclined surface 10 on the connection block 7 first contacts the ball 17 at the end of the insertion rod 14. The setting of the ball 17 can greatly reduce the friction between the inclined surface 10 and the end of the insertion rod 14; as the connection block 7 goes deeper, the inclined surface 10 generates a thrust on the insertion rod 14, pushing the insertion rod 14 upward into the spring hole 15, and at the same time, the compression plate 11 compresses the compression spring 12. When the connection block 7 is inserted to the position corresponding to the insertion hole 8 and the insertion rod 14, under the action of the rebound force of the compression spring 12, the insertion rod 14 is inserted into the insertion hole 8, thereby fixing the connection block 7; at the same time, the sealing block 6 is inserted into the sealing groove 3 to increase the connection sealing of the two hemispheres. Therefore, the present invention is quick and convenient for splicing the two hemispheres, and can quickly complete the fixation of the filling ball 16 and the splicing and fixation of the two hemispheres. At the same time, the splicing and fixing structures are arranged on the inner side of the two hemispheres. After the splicing is completed, the surface of the left hemisphere 1 and the right hemisphere 2 is smooth as before, and there is no other visible structure except the splicing seam, such as Figure 1 shown.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
