Description
Technical Field
The utility model belongs to the technical field of the trailer connector, especially, relate to a trailer socket with hasp structure.
Background
Existing trailer socket assemblies typically include a socket and a plug, and a cover plate is provided at one end of the socket to protect the jacks; for example, chinese utility model patent publication No. CN207116819U discloses a connector for a trailer. Although the plug connector improves the stability of connecting the plug and the socket, the cover plate is in a movable hinged state with the fixing plate of the socket due to the fact that the cover plate is lack of an effective locking piece, jolting or shaking in the running process of the trailer easily causes the cover plate to hit one side of the plug, poor contact between the socket and the plug is easily caused, and the service life of the plug connector is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the apron of current trailer connector and lack effective fixed defect, provide a trailer socket with hasp structure.
In order to achieve the purpose, the utility model relates to a trailer socket with a lock catch structure, which comprises a plug and a socket which are matched in a splicing way; a fixing piece is arranged at one end of the socket opposite to the plug; a cover plate is hinged to the fixed sheet; one side of the fixed plate, which is hinged with the cover plate, is matched with a screw; one end of the cover plate, which is opposite to the fixing piece, is provided with a first threaded hole matched with the screw; one end of the cover plate, which is opposite to the fixing piece, is also provided with a limiting hole matched with the screw; the axis of the limiting hole is intersected with the axis of the first threaded hole in space and forms an acute angle.
Further, a gasket is arranged on the screw rod; the gasket is connected with an anti-falling rope; the anti-falling rope is further connected with one end, back to the cover plate, of the fixing piece.
Further, the screw axis and the axis of the socket are parallel.
Furthermore, the bottom of the limiting hole is provided with a second threaded hole matched with the screw rod.
Furthermore, a plurality of limiting holes are formed in the cover plate; the axes of the limiting holes are positioned on the same vertical plane.
Further, the gasket is in threaded fit with the screw.
The utility model has the advantages that: the screw is respectively matched with the limiting hole and the first threaded hole, so that the limiting fixation of the cover plate in an opening state and a closing state can be respectively realized; the cover plate is prevented from hitting one side of the plug due to bumping or shaking of the vehicle, and the service life and the connection stability are improved.

Fig. 2 is a schematic structural view of the plug of fig. 1 inserted into a socket.
Fig. 3 is a partially enlarged schematic view of fig. 1.
In the figure, a plug 1, a socket 2, a fixing piece 3, a cover plate 4, a screw rod 5, a first threaded hole 6, a limiting hole 7, an anti-falling rope 8, a gasket 9 and a second threaded hole 10.
Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
A trailer socket with a locking structure as shown in fig. 1, 2 and 3 comprises a plug 1 and a socket 2 which are in plug-in fit; one end of the socket 2 opposite to the plug 1 is provided with a fixing piece 3; a cover plate 4 is hinged on the fixed plate 3; one side of the fixed plate 3, which is hinged with the cover plate 4, is matched with a screw rod 5; one end of the cover plate 4 opposite to the fixing piece 3 is provided with a first threaded hole 6 matched with the screw rod 5; one end of the cover plate 4 opposite to the fixing piece 3 is also provided with a limit hole 7 matched with the screw 5; the axis of the limiting hole 7 is intersected with the axis of the first threaded hole 6 in space and forms an acute angle.
In order to avoid the falling off when the screw 5 is not connected with the fixed sheet 3, a gasket 9 matched with threads is arranged on the screw 5; the gasket 9 is connected with an anti-drop rope 8; the anti-dropping rope 8 is also connected with one end of the fixing piece 3 back to the cover plate 4. The screw 5 axis is parallel to the axis of the socket 2. In order to be connected and fastened with the screw rod 5, the bottom of the limiting hole 7 is provided with a second threaded hole 10 matched with the screw rod 5. A plurality of limiting holes 7 are formed in the cover plate 4; the axes of the limiting holes 7 are on the same vertical plane.
As shown in fig. 3, when the cover plate 4 is in a closed state, the cover plate 4 is attached to the fixing piece 3; the screw rod 5 is connected with a first threaded hole 6 on the cover plate 4, so that the cover plate 4 is fixedly connected with the fixing plate 3. When the cover plate 4 is in an open state, as shown in fig. 2, in this state, the plug 1 is connected and matched with the socket 2, and the screw 5 is inserted into the limiting hole 7 and can be matched with the second threaded hole 10 in the limiting hole 7, so that the cover plate 4 and the screw 5 are fixed. Therefore, no matter whether the plug 1 and the socket 2 are in a connection state or not, the cover plate 4 is in an opening state or not, the cover plate 4 can be in a fixed state, the cover plate 4 cannot collide with the side wall of the plug 1, the connection stability of the plug 1 and the socket 2 is improved, and the service life is prolonged.
