Description

Improved sliding sleeve structure of universal joint

This creation is related to the sliding sleeve structure of a universal joint. In more detail, it refers to a kind of positioning that is stable and can always maintain the stability of the setting state, and at the same time has the convenience of being easy to be used and being convenient. The novel creation.

According to the well-known, such universal joints are mainly used for the connection of power tools (such as pneumatic or electric screwdrivers), and can be used for more construction difficulties and special deflections. Angle of work. Therefore, as shown in the fifth and sixth figures, for the well-known plane of such creation and its operation diagram, it can be seen from the figure that it is also composed of a cylindrical action end 10 having a universal joint 11 and a The insertion end 20 of the receiving groove 21 and a sliding sleeve 30 are formed, wherein the sliding sleeve 30 is sleeved on the outer periphery of the working end 10, and is acted upon by the top pin 12 which is raised by the spring 13 to make When the locked state of the axial direction is defined (ie, as shown in FIG. 5), the top pin 12 abuts against the corresponding leading edge of the sliding sleeve 30 to form a blocking action. At this time, the sliding sleeve 30 and the plug end 20 The connecting groove 21 is in a side-by-side relationship, so the working end 10 will not be able to be turned by the working angle; afterwards, when the working end 10 is to be turned, the first pin 12 must be pressed to cause it to fall. The blocking effect of the sliding sleeve 30 is released, and then the sliding sleeve 30 is pushed out to be disengaged from the stopping position of the joint receiving groove 21, thereby becoming an open state that can be bent (ie, shown in FIG. 6). At this time, the top pin 12 is hidden in the sliding sleeve.

Looking at this conventional product, although it seems to be simple in structural design, it must be aligned and indeed press the top pin 12 to smoothly slide the sliding sleeve 30. Under normal circumstances, these operating procedures are not obvious. It’s not right, but because the working objects or places of such tools are usually filled with a lot of oil and debris, plus the oil pollution and the possible limitation of the working space of the workers’ hands, if you want to press normally, When the top pin 12 is positioned, it is often troublesome to miss and slip. Therefore, in addition to the inconvenience of significantly reducing work efficiency, it is more likely to have doubts that it is difficult to operate quickly and smoothly, and thus it is necessary to be improved.

Therefore, in view of the above facts, the creator relies on his practical experience of practicing the industry for many years, actively betting on his efforts and actively researching and improving. This creation was born early; therefore, it is mainly aimed at the sliding of the sliding sleeve. The positioning operation and the ideal treatment of the structure are not only to simplify the operation mode, but also to greatly improve the positioning accuracy and overall operational efficiency, which is the main purpose of the creation.

Yes, it is mainly suitable for the working end. There are two sets of limit bead and abutting ring with appropriate spacing to match the corresponding bead groove set in the corresponding position inside the sliding sleeve, so that the sliding sleeve is properly Move to the desired limit position to achieve an open state that can be bent at an angle, or a locked state with a defined axial angle, thereby achieving the intended simple and quick control purpose.

In order to further understand the technical means and structural features of the creation, the preferred embodiment is described in detail with the drawings: First, please refer to the first, second, third and fourth figures, for the creation The preferred embodiment and the operation schematic diagram are as follows: a cylindrical action end 40 having a universal joint 41, and an external tool (not shown) receptacle 42 is provided at the open end; The insertion end 50 of the connecting groove 51 is provided at one end for connection with a power tool (not shown), and the other end receiving groove 51 is for pivoting end 40 universal joint a sliding sleeve 60, which is sleeved on the outer periphery of the working end 40 and can be appropriately slipped; and is characterized in that it is mainly adapted to the working end 40, and two sets of limiting bead 43 with appropriate spacing are provided. 44 and an abutting ring 45 for matching the corresponding bead groove 61 corresponding to the corresponding position inside the sliding sleeve 60, so that the sliding sleeve 60 is properly pushed to the desired defined position to respectively achieve the opening angle that can be bent. State, or the state of the lock that is limited by the axial angle.

Therefore, with the above structural design, it can easily move the sliding sleeve 60 to the set position to achieve the purpose of simple and quick control, and also can be simply locked by the limiting beadings 43, 44 and the corresponding bead groove 61. In order to achieve the best and most accurate positioning performance, it will be able to fully demonstrate its ease of use and practical value.

In addition, since the assembly structure of the universal joint 41 and the joint groove 51 is a common and widely used skill, it is well known to the industry, and it is not the feature of the creation, so the creator will not For details, please check.

Looking at the above, before the application, the creation of this creation has not only been found in similar products and related publications, but also has the practical value and positive benefits of "new" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain The protection of the patent law, 提出 apply in accordance with the law.
