Technical Field
[0001] This utility model relates to the field of pharmaceutical packaging tools, and in particular to a rubber hammer for venting air from pharmaceutical packaging. Background Technology
[0002] In pharmaceutical packaging, especially when using cans, it is often necessary to tap the can to expel the gas inside, thereby ensuring the quality of the packaging of the medicine inside.
[0003] Existing technologies typically use rubber hammers for venting air, but these hammers have the following drawbacks: 1. The hammer body is made of rubber, resulting in a low overall density. While maintaining the advantage of a small structural size, the hammer's striking force cannot be reliably guaranteed under manual striking with the same force. 2. The connection between the hammer handle and the hammer body is not reliable enough, making them prone to breakage and damage. 3. Existing rubber hammers have a simple structure, resulting in limited functionality.
[0004] Therefore, how to provide a rubber hammer for venting air from pharmaceutical packaging with a simpler and more reasonable structural design that combines the advantages of small structural size and reliable striking force, better avoids breakage of the hammer handle and hammer body, and has more functions has become a technical problem to be solved by those skilled in the art. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a rubber hammer for venting air in pharmaceutical packaging with a simpler and more reasonable structural design, which can combine the advantages of small structural size and reliable striking force, better avoid breakage of the hammer handle and hammer body, and has more functions.
[0006] To achieve the above objectives, this utility model provides a rubber hammer for venting air from pharmaceutical packaging, comprising a rubber hammer body, wherein the rubber hammer body includes a hammer body and a hammer handle connected and fixed to the hammer body; characterized in that; the hammer body includes a middle section in the middle, an upper section and a lower section are respectively connected and disposed at the upper and lower ends of the middle section, and the hammer handle is also connected and disposed on one side of the middle section; the middle section of the hammer body is made of metal.
[0007] Thus, in the aforementioned rubber hammer structure for venting air from drug packaging, the hammer body is made of metal in the middle section, resulting in a higher overall density structure. This allows for a greater hammer mass without increasing the hammer size, and when used for venting air from drug packaging, it combines the advantages of small structural size with reliable striking force.
[0008] Furthermore, the lower section of the hammer body has an overall cylindrical structure design, and a rounded corner structure is provided at the lower end of the lower section of the hammer body.

[0016] In this way, the structural design of the middle section of the hammer body is more reasonable, and it can better connect with the upper and lower sections of the hammer body.
[0017] As an optimization, multiple vertical through holes are arranged in an array along the circumferential direction at the edge of the upper surface of the counterweight head, and connecting strips are installed in the through holes. The two ends of the connecting strips are respectively connected to the lower end face of the upper section of the hammer body and the upper end face of the lower section of the hammer body.
[0018] In this way, by setting through holes and connecting strips, the upper section, lower section and middle section of the hammer body can be better connected together and form a better whole.
[0019] As an optimization, a vertical through-hole is provided at the center of the connector end face, and a connecting post is provided in the through-hole, with the upper and lower ends of the connecting post respectively connected to the bottom surface of the connecting hole.
[0020] In this way, by setting the clearance hole and connecting column, the upper section, lower section and middle section of the hammer body can be better connected together, resulting in better integration.
[0021] Furthermore, the connecting strip, connecting column, upper section of the hammer body, and lower section of the hammer body are integrally injection molded.
[0022] Furthermore, there are six through holes arranged in an array along the circumference.
[0023] As an optimization, the connector includes an inner section, a middle section, and an outer section from the inside out. The diameter of the middle section is smaller than the diameters of the inner and outer sections to form an annular connecting groove between the inner and outer sections. A mating flange is formed on the inner circumferential surface of the connecting hole at a position corresponding to the connecting groove and fits into the connecting groove.
[0024] In this way, the connector's structural design is simpler and more reliable, enabling better connection with the upper and lower sections of the hammer body.
[0025] Furthermore, the outer section of the connector is designed with a frustum-shaped structure, with a smaller outer diameter and a larger inner diameter.
[0026] As an optimization, a horizontally positioned fixing hole is provided at the center of the outer peripheral surface of the counterweight head, and one end of the hammer handle is inserted into the fixing hole. A vertically downward-positioned pin hole is provided on the upper surface of the counterweight head, and a pin is provided in the pin hole, with the lower end of the pin extending into the fixing hole and inserted into the end of the hammer handle.
