Description

Socket connection structure

The present invention relates to hand tools, and more particularly to a socket configuration for a mouthpiece.

The nozzle (1) as shown in the first figure is generally used as a connecting member for connecting to the outside in a closed hydraulic circuit such as a hydraulic brake system in the application of the prior art, so that the user can replace the circuit in the circuit. In addition to the use of the fluid, in addition to the need to apply a rotary action to release or close the connection between the inlet port (1a) of the discharge nozzle (1) and the hydraulic circuit, it is also necessary to connect the pipe with the appropriate nozzle (1) The push-type connection end (1b) is connected to the state in which the connection line is connected to the hydraulic circuit via the discharge nozzle (1).

In order to facilitate the foregoing operations, the kit tool (2) as shown in the second and third figures is disclosed in the prior art to facilitate the user to simultaneously apply the rotation force to the mouthpiece (1). Referring to the connector (1b), and referring to the first figure, in order to apply a rotational force to the mouthpiece (1), the kit tool (2) is a hollow sleeve made of metal. (2a) is sleeved on the nut (1c) of the mouthpiece (1) located inside the connecting end (1b), transmitting a force applied by the user to rotate the mouthpiece (1), and simultaneously at the hollow sleeve (1) 2a) coaxially and coaxially embedded with a flexible elastic sleeve (2b) for forming a radially expandable and resilient elastic joint nozzle for tightly fitting over the joint end (1b) To form a passage that communicates with an external connecting line.

Although the kit tool (2) makes it easy for the user to operate the nozzle (1), there are many different configurations in the prior art to meet the equipment requirements of different hydraulic circuits. Or the size of the mouthpiece is used separately, and the kit tool (2) can be used with different nozzles, depending on whether the kit tool (2) has to be embedded with the nut of the nozzle, and whether it is Closely connected to the connection end of the nozzle, but the testament is that due to the size and shape of the connection end of the nozzle, there is no suitable standard to be followed in the existing industrial product standards, and therefore have different sizes or shapes. The tapping port of the connecting end is stored in the conventional method, but in this way, the kit tool (2) is limited to its own structural limitation and can only be applied to the tap of the smaller range of the connecting end. Unload and connect.

Specifically, the kit tool (2) is limited by the fact that it is a flexible sleeve (2b) as a socket structure with the nozzle connection end (1b). The deformation of the sleeve (2b) can only be achieved smoothly within a small range of variation by the characteristics of the material itself, compared to conventional nozzles of different sizes or shapes. (2) It is still difficult to use it in different nozzles with large connection end size or shape variability, which makes the kit tool (2) limited in scope and relatively inconvenient for users to obtain convenience.

Therefore, the main object of the present invention is to provide a socket structure for a mouthpiece which is suitably sleeved between different nozzles having a large difference in size to improve user convenience and reduce Reduce the burden on the needs of different sized tools or equipment.

Between the second body and the first body to allow the second body to change shape or position in the deformation space.

Wherein, the deformation of the second body portion is not limited to deformation which is not eccentric, and therefore, the position, size and shape of the deformation space are not limited.

Providing the average deformation, the deformation space is annular or tubular, and the center of curvature is coaxially corresponding to the hole axis of the second sleeve hole, so that the second socket is in the second When the sleeve hole is combined with the mouthpiece end of the mouthpiece, the corresponding deformation or displacement generated by the sleeve hole can be made around the connection end of the mouthpiece.

In addition, the formation of the deformation space is exemplified by a kit tool of the prior art, which can be obtained by removing a wall of a certain depth inside the sleeve and/or cutting a wall of a certain depth outside the elastic sleeve.

In other words, the second socket member further includes a protruding rib protruding from the peripheral end surface of the second body portion and abutting against the inner wall of the receiving space at the end, thereby The peripheral side end surface of the second body portion is spaced apart from the inner side wall surface of the accommodating space, thereby forming the change Shape space.

Wherein, the protruding rib is preferably an annular axis and the ring axis is coaxial with the hole axis of the second sleeve hole.

Or the first socket member may further include a recess recessed in the inner wall of the circumference of the receiving space, such that the deformation space is between the bottom of the groove and the peripheral end surface of the second body portion. between.

Wherein, the groove is also annular and the ring axis is coaxial with the axis of the first set of holes.
