The utility model provides an aim at creats the mounting tool of bolt, nut in narrow and small space, can improve bolt installation effectiveness, reduces the operation degree of difficulty.
The utility model provides a bolt and nut tightening tool, a serial communication port, the instrument body is a rigid load board, be connected with the handle of screwing up in one side of load board, opposite side at the load board is connected with first horizontal seat and second horizontal seat, the direction of first horizontal seat and second horizontal seat is opposite with the direction of screwing up the handle, first horizontal seat is located the below of second horizontal seat, be equipped with vertical nut spacing groove on the first horizontal seat, this nut spacing groove matches with the diameter of nut, the second is inlayed and is had vertical bolt spacing groove, this bolt spacing groove matches with bolt head diameter, the bolt spacing groove is a ratchet structure, the direction of rotation of this ratchet is opposite with the direction of rotation of screwing up the handle, the coaxial line of the nut spacing groove on the first horizontal seat and the bolt spacing groove on the second horizontal seat is parallel with the load board.
The end head of the second horizontal seat is connected to the bearing plate of the tool body in a sliding manner.
The end head of the first horizontal seat is connected to a bearing plate of the tool body in a sliding manner.
When the nut screwing tool is used, a bolt is placed in the assembling hole, a nut matched with the bolt is placed in a nut groove in the upper surface of a first horizontal seat of the screwing tool for limiting, the screwing tool is moved, and the first horizontal seat and the nut are conveyed to the position below the bolt; the height of the second horizontal seat is adjusted, and a ratchet wheel on the second horizontal seat is sleeved at the head of the bolt from the upper part of the bolt, so that the rotation direction of the ratchet wheel is opposite to that of the tightening handle; the screwing handle is rotated, and the bolt and the nut are driven to rotate relatively through the ratchet wheel on the second horizontal seat and the nut groove on the upper surface of the first horizontal seat, so that the bolt and the nut are screwed; when the screwing tool is unloaded, the second horizontal seat is moved upwards to be separated from the head part of the bolt, and the first horizontal seat is moved downwards to be separated from the nut.
The beneficial effect of this application lies in: the bolt and nut screwing tool effectively solves the problems that nuts are difficult to place and the time for screwing bolts is long in a narrow space, is suitable for screwing bolts and nuts of various specifications in all narrow spaces, and can be popularized to connection of bolt and nuts of various types.
The present application is described in further detail below with reference to the accompanying drawings of embodiments.
Drawings
Fig. 1 is a schematic view of a bolt and nut tightening tool.
Fig. 2 is a schematic view of a first horizontal seat structure.
Fig. 3 is a schematic view of a second horizontal seat structure.
Fig. 4 is a schematic structural view of another embodiment of the first horizontal base.
The numbering in the figures illustrates: the device comprises a bearing plate 1, a first horizontal seat 2, a second horizontal seat 3, a handle 4, a nut limiting groove 5, a bolt head ratchet wheel 6, a slide block 7, a nut ratchet wheel 8 and a bolt ratchet wheel shifting piece 9.
Detailed Description
Referring to the drawings, the bolt and nut tightening tool of the application is characterized in that a tool body is a rigid bearing plate 1, one side of the bearing plate 1 is connected with a screwing handle 4, the other side of the bearing plate 1 is connected with a first horizontal seat 2 and a second horizontal seat 3, the directions of the first horizontal seat 2 and the second horizontal seat 3 are opposite to the direction of the screwing handle 4, the first horizontal seat 2 is positioned below the second horizontal seat 3, the first horizontal seat 2 is provided with a vertical nut limiting groove 5, the nut limiting groove 5 is matched with the diameter of the nut, a vertical bolt limiting groove is embedded on the second flat seat 3, the bolt limiting groove is a bolt head ratchet wheel 6 matched with the diameter of the head of the bolt, the rotation direction of the bolt head ratchet wheel 6 is opposite to the rotation direction of the tightening handle 4, and the coaxial line of the nut limiting groove 5 on the first horizontal seat and the bolt head ratchet wheel 6 on the second horizontal seat is parallel to the bearing plate 1.
In the implementation, the end of the second horizontal seat is provided with a sliding block 7, the sliding block 7 is provided with a sliding chute sleeved on the bearing plate, and the second horizontal seat is connected to the bearing plate 1 of the tool body in a sliding manner through the sliding block 7.
In order to facilitate the adjustment of the distance between the first horizontal seat 2 and the second horizontal seat 3, the bolt and nut assembling operation is already applied, in the embodiment, the end of the first horizontal seat 2 may also adopt a slider structure like the second horizontal seat 3, and is slidably connected to the force bearing plate 1 of the tool body.
In practice, the nut limiting groove 5 on the first horizontal seat 2 may be a regular hexagonal groove matching with the nut shape, as shown in fig. 4, or the nut limiting groove 5 shown in fig. 2 may also be embedded with a nut ratchet 8, but it is noted that the rotation direction of the nut ratchet 8 must be opposite to the rotation direction 6 of the bolt ratchet.
When the nut screwing tool is used, a bolt is placed in the assembling hole, a nut matched with the bolt is placed in the nut limiting groove 5 on the upper surface of the first horizontal seat 2 of the screwing tool for limiting, the screwing tool is moved, and the first horizontal seat 2 and the nut are conveyed to the position below the bolt; the height distance between the second horizontal seat 3 and the first water bottle seat is adjusted to adapt to the matching of the lower end of the nut and the lower end of the bolt, the bolt head ratchet wheel 6 on the second horizontal seat 3 is sleeved on the head of the bolt from the upper part of the bolt, and the rotation direction of the bolt head ratchet wheel 6 is opposite to that of the tightening handle 4; the screwing handle is rotated, and the bolt and the nut are driven to rotate relatively through the ratchet wheel on the second horizontal seat and the nut groove on the upper surface of the first horizontal seat, so that the bolt and the nut are screwed; when the screwing tool is unloaded, the second horizontal seat is moved upwards to be separated from the head part of the bolt, and the first horizontal seat is moved downwards to be separated from the nut.
