[0024] Please refer to Figures 2 to 4 , a tightening wrench structure for a watertight connector locking sleeve of the present utility model includes a working head 10 and an extension handle 20 integrally formed. The working head 10 is provided with a hollow opening groove 11, and the opening groove 11 is used to be matched with the outer structure of the watertight connector locking sleeve 40, so that the watertight connector locking sleeve 40 can be disposed in the opening groove 11 in a matching manner, and then the close docking operation between the working head 10 and the watertight connector locking sleeve 40 is completed. By rotating the extension handle 20, the working head 10 is driven to rotate together, so as to achieve the effect that the working head 10 easily drives the watertight connector locking sleeve 40 to rotate. The structure is simple, and it is more labor-saving when installing and disassembling the watertight connector, thereby ensuring the reliability of the electrical contact of the watertight connector.
[0025] In this embodiment, the watertight connector locking sleeve 40 is made of rubber. One end of the watertight connector locking sleeve 40 is correspondingly provided with the female end structure of the watertight connector. A threaded portion is provided inside the watertight connector locking sleeve 40 for threaded connection with the male end structure of the watertight connector to achieve the electrical contact effect of the watertight connector. A plurality of strip-shaped convex ribs 41 are spaced apart on the outer side of the watertight connector locking sleeve 40. The strip-shaped convex ribs 41 protrude from the surface of the outer side of the watertight connector locking sleeve 40 by a preset distance, so as to increase the friction effect between the operator's hand and the watertight connector locking sleeve 40, so that the operator can rotate the watertight connector locking sleeve 40 well by using the blocking effect of the strip-shaped convex ribs 41 in the early stage; in this embodiment, the male end structure and the female end structure of the watertight connector are conventional designs in the art and will not be elaborated here.
[0026] In one embodiment, the cross-section of the working head 10 is circular. The tangent of the edge of the working head 10 coincides with the edge of the extension handle 20, which facilitates the injection molding effect of the working head 10 and the extension handle 20, and further makes the connection between the integrally formed working head 10 and the extension handle 20 more stable.
[0027] In one embodiment, the opening groove 11 is recessed with internal tooth grooves 111 that match the strip-shaped ridges 41. A docking portion 12 is provided between two adjacent internal tooth grooves 111. The strip-shaped ridges 41 are correspondingly disposed in the internal tooth grooves 111, thereby achieving the effect of firmly fixing the locking sleeve in the opening groove 11. By rotating the extension handle 20, the working head 10 is rotated together, thereby realizing the effect that the working head 10 easily drives the locking sleeve 40 of the watertight connector to rotate. The structure is simple, and it is more labor-saving during the installation and disassembly of the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0028] Furthermore, the internal tooth groove 111 includes a docking groove 1111 and stepped portions 1112 provided on both sides of the docking groove 1111, thereby increasing the accommodating space of the internal tooth groove 111 and better coping with the deformation changes of the strip-shaped ridges 41 due to stress. During actual use, after the strip-shaped ridges 41 are placed in the internal tooth grooves 111, the upper half of the strip-shaped ridges 41 enters the docking groove 1111, and the side edges of the lower half of the strip-shaped ridges 41 are separated from the side edges of the internal tooth grooves 111 by the distance of a stepped portion 1112. After the strip-shaped ridges 41 are placed in the internal tooth grooves 111, there is a gap between the strip-shaped ridges 41 and the side walls of the internal tooth grooves 111, thereby better coping with the deformation changes of the strip-shaped ridges 41 due to stress.
[0029] Furthermore, the cross-section of the docking portion 12 is semicircular, so that there is a gap between the strip-shaped ridges 41 and the docking portion 12 after the strip-shaped ridges 41 are placed in the internal tooth grooves 111, thereby better coping with the deformation changes of the strip-shaped ridges 41 due to stress.
[0030] To ensure that the working head 10 does not cause cutting damage to the strip-shaped ridges 41 when driving the locking sleeve 40 of the watertight connector to rotate, the thickness of the working head 10, that is, the width of the internal tooth groove 111, should not be less than 20 mm. In addition, to ensure that the working head 10 does not affect the docking effect between the female end and the male end of the watertight connector when driving the locking sleeve 40 of the watertight connector to rotate, the thickness of the working head 10, that is, the width of the internal tooth groove 111, is preferably not greater than the length of the locking sleeve 40 of the watertight connector. Thus, while realizing the effect that the working head 10 easily drives the locking sleeve 40 of the watertight connector to rotate, it can also ensure the docking effect between the female end and the male end of the watertight connector and reduce the possibility of damage to the strip-shaped ridges 41.
[0031] In one embodiment, a handle 30 is provided at the end of the extension shank 20, and the handle 30 is arranged perpendicular to the extension shank 20; alternatively, the extension shank 20 and the handle 30 can also be designed in a non-perpendicular state according to needs, but this structure is not convenient for the operator to hold, so the perpendicular design of the extension shank 20 and the handle 30 is the preferred structure; after the operator holds the handle 30, the extension shank 20 is driven to rotate, so that the working head 10 rotates together, realizing the effect that the working head 10 easily drives the watertight connector locking sleeve 40 to rotate. The structure is simple, more labor-saving when installing and disassembling the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0032] Furthermore, the handle 30 can be fixedly connected to the end of the extension shank 20 by welding; after the operator holds the handle 30, the extension shank 20 is driven to rotate, so that the working head 10 rotates together, realizing the effect that the working head 10 easily drives the watertight connector locking sleeve 40 to rotate. The structure is simple, more labor-saving when installing and disassembling the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0033] Alternatively, a threaded groove is provided at the end of the extension shank 20, and a docking convex post is provided at one end of the handle 30. The docking convex post is fixed in the threaded groove by a threaded connection method, thereby realizing the fixed connection between the handle 30 and the end of the extension shank 20; after the operator holds the handle 30, the extension shank 20 is driven to rotate, so that the working head 10 rotates together, realizing the effect that the working head 10 easily drives the watertight connector locking sleeve 40 to rotate. The structure is simple, more labor-saving when installing and disassembling the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0034] In one embodiment, the handle 30 is of a cylindrical structure, and a hollow sleeve is provided on the outer side of the handle 30. The inner diameter of the sleeve is larger than the outer diameter of the handle 30, so that the sleeve can rotate freely on the outer side of the handle 30. The operator can also drive the extension shank 20 to rotate by holding the sleeve structure on the outer side of the main handle 30; in addition, the handle 30 changes its position as the extension shank 20 rotates. Through the sleeve structure, the operator does not need to adjust the holding angle and can automatically adjust by the rotation of the sleeve on the handle 30, making it easier and more convenient for the operator to rotate the extension shank 20; after the operator holds the sleeve on the outer side of the handle 30, the extension shank 20 is driven to rotate, so that the working head 10 rotates together, realizing the effect that the working head 10 easily drives the watertight connector locking sleeve 40 to rotate. The structure is simple, more labor-saving when installing and disassembling the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0035] Furthermore, a limiting convex ring is provided at the upper end of the handle 30 to place the sleeve on the handle 30 and prevent the sleeve from detaching from the handle 30 and affecting the use effect of the wrench structure.
[0036] In one embodiment, the working head 10, the extension shank 20 and the handle 30 are all made of high-strength structural steel.
[0037] When the present utility model is specifically used, when the male end socket of the watertight connector is docked with the female end plug of the watertight connector, that is, the watertight connector locking sleeve 40 with the female end structure of the watertight connector, initially, the operator uses hand force to pinch and rotate the watertight connector locking sleeve 40. When the watertight connector locking sleeve 40 is tightened to about one-third of its stroke, since the watertight connector locking sleeve 40 is made of rubber, at this time, the rubber tissue is stressed and the resistance makes it difficult to tighten. Then, the operator closely docks the opening groove 11 of the working head 10 of the wrench structure with the outer edge of the watertight connector locking sleeve 40, and rotates the extension shank 20 by holding the handle 30 so that the working head 10 also rotates accordingly. By applying force to the side of the strip-shaped rib 41 with the side edge of the internal tooth groove 111 in the opening groove 11, based on the principle of leverage, the effect of easily driving the watertight connector locking sleeve 40 to rotate by the working head 10 can be achieved without much effort. The structure is simple, more labor-saving during the installation and disassembly of the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0038] In summary, for the tightening wrench structure of the watertight connector locking sleeve 40 of the present utility model, by integrally forming the working head 10 provided with the opening groove 11 and the extension shank 20, the watertight connector locking sleeve 40 can be properly arranged in the opening groove 11, and then the close docking operation between the working head 10 and the watertight connector locking sleeve 40 can be completed. By rotating the extension shank 20, the working head 10 rotates accordingly, so as to achieve the effect of easily driving the watertight connector locking sleeve 40 to rotate by the working head 10. The structure is simple, more labor-saving during the installation and disassembly of the watertight connector, and further ensures the reliability of the electrical contact of the watertight connector.
[0039] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
