[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example
[0023] Grease nipple connectors, such as Figure 1-Figure 3 As shown, it includes a connecting piece main body 1, and the front and rear ends of the connecting piece main body 1 are both provided with external threads. The connecting piece main body 1 is provided with a wrench connecting part 2 at a position close to the rear end external thread, and the wrench connecting part 2 is provided with a tightening prompt component, which includes: an abutment 3 protruding from the surface of the wrench connecting part 2 and used to abut against the rear end external thread connection object, and the abutment 3 is slidably set on the wrench connecting part 2; a prompting part 4 is located on the side of the wrench connecting part 2 away from the external thread, and is used to be transmission-connected with the abutment 3, and the prompting part 4 is slidably set on the wrench connecting part 2; when the connecting piece main body 1 is tightened by the wrench connecting part 2, the abutment 3 abuts against the rear end external thread connection object, the abutment 3 is displaced, and abuts against the prompting part 4 to push the prompting part 4 to protrude from the surface of the wrench connecting part 2, so that the staff can know the status of the tightening process by touching the prompting part 4, avoiding over-tightening or under-tightening.
[0024] like Figure 3 As shown, a groove 5 is provided on the portion of the prompt member 4 that protrudes from the surface of the wrench connection part 2, so that when the abutment member 3 pushes the prompt member 4 to move outward, the staff can better determine the tightening degree by touching the extent to which the groove 5 moves on the surface of the wrench connection part 2.
[0025] At the same time Figure 2-Figure 3As shown, the wrench connecting part 2 is provided with a sliding groove 6 for extending one end of the abutment 3 to the outside, and the abutment 3 can slide along the direction of the sliding groove 6, so that when the connecting part body 1 is tightened, the abutment 3 will first abut against the connecting part, and then rotate as the wrench continues to tighten the wrench connecting part 2. Since the abutment 3 is in an abutting state, it is in a relatively static state relative to the connecting part, but is in an active state relative to the wrench connecting part 2. By utilizing the sliding groove 6, the friction resistance when relative sliding occurs between the abutment 3 and the wrench connecting part 2 is reduced, and one end of the prompting part 4 extends into the inside of the sliding groove 6, so that when the abutment 3 moves along the abutment 3, it can stably abut against the prompting part 4 and push the prompting part 4 to move outward.
[0026] like Figure 2 As shown, the slide groove 6 is configured as an arc structure, and the arc structure enables the abutment member 3 to rotate and move better along the wrench connection portion 2.
[0027] like Figure 3 As shown, the slide 6 is provided with a translation area 7 and a lifting area 8, and the extended end of the prompt member 4 is located in the lifting area 8. Through the partition setting, it is convenient for the staff to move the abutment member 3 to the initial position during installation.
[0028] like Figure 3 As shown, one end of the abutting member 3 and the prompting member 4 for abutting each other is set as an arc structure. The arc structure is used to reduce the friction resistance generated when the abutting member 3 and the prompting member 4 abut, thereby improving the direct push transmission efficiency.
[0029] like Figure 3 As shown, the opening on the wrench connecting portion 2 for the prompt member 4 to extend to the outside is configured as a necked structure, which prevents the prompt member 4 from falling off.
[0030] Among them Figure 2-Figure 3 As shown, a guide plate for covering the slide groove 6 is fixedly connected to the wrench connecting part 2, and an arc-shaped through-groove for the abutment 3 to pass through is provided on the guide plate 9. The guide plate 9 prevents the abutment 3 from falling off from the wrench connecting part 2, wherein the guide plate 9 is configured as a split structure, thereby facilitating the installation of the abutment 3 on the guide plate 9 and ensuring that the abutment 3 slides, while the prompting member 4 cannot pass through the arc-shaped through-groove, thereby ensuring the usability of the overall structure.
[0031] Working principle: In the process of tightening the connector body 1 with a wrench, the abutment 3 will first abut against the connecting part, and then the wrench connecting part 2 will rotate as the wrench continues to tighten. Since the abutment 3 is in an abutment state, it is relatively stationary relative to the connecting part, but is in an active state relative to the wrench connecting part 2, so that the abutment 3 moves from the translation area 7 to the lifting area 8. In the process of moving from the translation area 7 to the lifting area 8, the part of the abutment 3 protruding from the surface of the wrench connecting part 2 will gradually decrease. When the abutment 3 is level with the surface of the wrench connecting part 2, the wrench connecting part 2 just completes the fit with the surface of the connecting part to achieve the tightening effect. In the process of moving from the translation area 7 to the lifting area 8, the abutment 3 will abut against the prompt part 4 and push the prompt part 4 to protrude from the surface of the wrench connecting part 2, so that during the tightening process, the staff only needs to touch the prompt part 4 with their fingers to clearly know the tightening status.
[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
