Description

Technical Field

[0001] This utility model relates to the field of air pump equipment, and in particular to a novel universal leather cup. Background Technology

[0002] An air pump is a device that removes or adds air to a closed space. Air pumps are mainly divided into electric air pumps, manual air pumps, and foot-operated air pumps. Electric air pumps use electricity to continuously compress air, generating pressure. Air pumps achieve their inflation function by repeatedly compressing an air bladder within a rubber cup; the size of the air bladder and the air bladder itself affect the pump's pressure and flow rate.

[0003] The existing universal rubber cup has a very small chamfer at the connection between the ball head and the foot. During automated assembly, this leads to a certain percentage of breakages. Furthermore, friction with different plastic parts occurs during operation, shortening the lifespan of the rubber cup and affecting the performance of the air pump. Therefore, a new type of universal rubber cup is needed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a new type of universal leather bowl is provided.

[0005] This utility model is achieved through the following solution:

[0006] A novel universal leather cup includes a hollow cylindrical air bladder, one end of which is connected to an air cap, the space between which forms an air chamber, the other end of which is connected to a solid body, the solid body is connected to a fixed post, the fixed post is connected to a ball head, the ball head is connected to a buffer post, and the buffer post is connected to a column foot.

[0007] The air cover is a hollow spherical structure. The air cover includes a base, a body and a top seat. One side of the base is connected to the air bladder, the other side of the base is connected to the body, the other side of the body is connected to the top seat, and the other side of the top seat is connected to the solid body.

[0008] The diameter of the base is larger than the diameter of the top seat.

[0009] The entity includes a base, a main body, and a platform, which are connected in sequence. The base is connected to the top seat, and the platform is connected to the fixed column.

[0010] The cross-section of the entity is trapezoidal, and the diameter of the base is larger than the diameter of the platform.

[0011] The beneficial effects of the utility model are:

[0012] 1. This utility model discloses a novel universal leather cup. The solid body is made into a conical structure at a certain angle, which reduces the material and solves the problem of friction between the leather cup and the plastic parts during movement, thereby increasing the service life of this utility model.

[0013] 2. This utility model provides a novel universal leather cup that adds a buffer post between the ball head and the column foot, increases the chamfer at the connection between the ball head and the column foot, increases its strength, and solves the problem of broken feet during assembly.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 2-3 As shown, a novel universal air pump includes a hollow cylindrical air bladder 1. One end of the air bladder 1 is connected to an air cap 2, forming an air chamber 4. The other end of the air cap 2 is connected to a solid 3, which is connected to a fixing post 5. The fixing post 5 is connected to a ball head 6, the ball head 6 is connected to a buffer post 7, and the buffer post 7 is connected to a column base 8. This invention increases the diameter of the air bladder 1 and the solid 3 while reducing the height of the air chamber 4, allowing the air bladder to maintain high flow and pressure during reciprocating compression, thus enabling the air pump to inflate with high flow and pressure.

[0020] The chamfer of the buffer post 7 can be 120°-150°. This utility model provides a new type of universal cup with a buffer post between the ball head and the post foot, which increases the chamfer at the connection between the ball head and the post foot, increases its strength, and solves the problem of broken feet during assembly.

[0021] In the specific implementation process, the diameters of airbag 1 and solid 3 are increased to a certain extent to increase airflow. Then, the height of air chamber 4 is reduced to decrease its space, thereby increasing air pressure. For example... Figure 1 As shown, the air cover 2 is a hollow spherical structure, comprising a base 21, a body 23, and a top seat 22. One side of the base 21 is connected to the airbag 1, the other side of the base 21 is connected to the body 23, the other side of the body 23 is connected to the top seat 22, and the other side of the top seat 22 is connected to the solid 3. The diameter of the base 21 is larger than the diameter of the top seat 22. This invention optimizes the chamfering of the airbag 1 and the structure of the air cover 2, specifically the chamfering at the connection between the airbag 1 and the solid 3, so that the flow rate and pressure of the air pump can be maintained at a high level simultaneously during use.

[0022] The entity 3 includes a base 31, a main body 33, and a platform 32, which are sequentially connected. The base 31 is connected to the top seat 22, and the platform 32 is connected to the fixed column 5. The cross-section of the entity 3 is trapezoidal, and the diameter of the base 31 is larger than the diameter of the platform 32. Existing entities generally adopt a cylindrical structure. This utility model provides a novel universal leather cup by making the entity 3 into a conical structure at a certain angle, which reduces material usage and solves the problem of friction between the leather cup and the plastic parts during movement, thus increasing the service life of this utility model. In practical applications, the universal leather cup of this application consists of three leather cups connected to a plastic part (not shown in the attached drawings). The specific working process and principle are well-known technologies and will not be described in detail here.

[0023] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
