Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to the installation fastening tool for the vertical air duct shown in the accompanying drawings 1-5, the installation fastening tool comprises an assembly part for assembling and fastening the bolts and nuts of the air duct at an upper and lower interval, because the space between the vertical air duct and the side wall of the vertical air duct is narrower, when the bolts and nuts are manually penetrated at the position where the air duct is connected, the space is limited, the penetrating difficulty is high, and meanwhile, the bolts and the nuts are not matched and connected when the bolts and nuts are penetrated, so that the bolts and the nuts are very easy to fall off, the bolts and the nuts can be assembled and positioned outside the vertical air duct through the assembly part, and then the assembly part is extended into the connecting hole of the air duct in the vertical air duct to be assembled, so that the problem that the space is limited and difficult to operate can be solved, and the problem that the bolts and the nuts fall off due to manual penetrating can be avoided.
In order to facilitate the driving cooperation of the bolt and the nut on the assembly part, so as to realize the connection of the air pipe, the driving mechanism is connected with the assembly part and drives the bolt to rotate vertically, the bolt approaches to the direction of the nut under the driving of the driving mechanism, and the bolt passes through the connecting hole of the air pipe and then cooperates with the nut to realize the fastening connection of the air pipe. The driving mechanism can vertically drive the matching of the bolt and the nut, and the driving mechanism can horizontally extend out of the air pipe along the assembly part so as to provide a larger operation space, thereby solving the problem that the space between the air pipe and the side wall of the vertical shaft is too narrow and the operation space is limited.
Specifically, as shown in fig. 1, the assembly member includes a U-shaped plate 1, a bolt assembly sleeve 21 rotatably nesting the bolt is provided at an inner top side thereof, and a nut assembly sleeve 22 rotatably spacing nesting the nut is provided at an inner bottom side thereof (which is preferably a hexagonal cylinder structure preventing rotation of the nut). Preferably, the nut assembling sleeve 22 and the inner bottom side of the U-shaped plate 1 are through structures, and the through structures are used for allowing the bolt to pass through the end of the bolt after being sleeved and matched with the nut, so that the rotation fastening of the bolt and the nut is realized, and meanwhile, the nut is kept in a rotation limiting state.
Before the air pipe is connected, bolts and nuts are assembled in the bolt assembling sleeve 21 and the nut assembling sleeve 22 in sequence, then the whole of the bolts and the nuts extend into the connecting hole of the air pipe from the space between the air pipe and the side wall of the vertical shaft, so that the bolts correspond to the upper side of the connecting hole, the nuts correspond to the lower side of the connecting hole, and then the bolts penetrate through the connecting hole and are connected and fastened with the nuts in a matched mode through a driving mechanism.
Specifically, as shown in fig. 2, the driving mechanism includes a driving head 3 vertically rotatably penetrating the top side of the U-shaped board 1 and the bolt assembly sleeve 21 and connected with the bolt. The preferred bolt selects the hexagon socket head cap screw, and the bottom of driving head 3 then is the hexagon structure of cooperation bolt, can drive the rotation of bolt through the rotation of driving head 3, simultaneously because driving head 3 wears to establish in U template 1 top side and bolt assembly sleeve 21, consequently, driving head 3 is in rotatory in-process compare U template 1 moves down, can drive the bolt and pass the connecting hole and be connected with the nut.
In order to drive the driving head 3 outside the air duct, as shown in fig. 2, a straight tube 41 penetrating the driving head 3 is provided on the top side of the U-shaped plate 1, a deformed tube 42 (preferably a bellows or other bendable tube) and a horizontal tube 43 are sequentially connected to the top end of the straight tube 41, the outer end of the horizontal tube 43 can be horizontally extended to the outside of the air duct by the deformed tube 42, and in this configuration, a deformed rod 5 (preferably a flexible connecting rod/shaft) and a horizontal rod 6 sequentially penetrating the deformed tube 42 and the horizontal tube 43 are connected to the top end of the driving head 3.
In operation, one hand holds the horizontal tube 43, the other hand drives the horizontal rod 6 to rotate and drives the deformation rod 5 and the driving head 3 to rotate, and simultaneously drives the horizontal rod 6 to the inner side of the horizontal tube 43, so that the driving head 3 can be driven to move downwards in the rotating process, and the bolts are driven to pass through the connecting holes to be matched and fastened with the nuts. Preferably, the length of the deformation rod 5 is greater than that of the deformation tube 42, so that two ends of the deformation rod 5 can be extended into the straight tube 41 and the horizontal tube 43, and the movement blocking caused by the driving head 3 and the horizontal rod 6 entering into the deformation tube 42 is avoided. After the connection of the bolt and the nut is completed (because the top end of the bolt is separated from the bolt assembling sleeve 21 when the bolt moves downwards to be connected with the nut), the horizontal rod 6 is pulled reversely, so that the driving head 3 is separated from the top end of the bolt, and then the horizontal pipe 43 is slightly rocked downwards to separate the nut from the nut assembling sleeve 22, so that the whole tool is separated from the bolt and the nut, and the tool is taken out from the air pipe and the side wall of the vertical shaft to fasten the next connecting hole.
Before the bolt and the nut are connected, in order to avoid the problem that the bolt falls off from the bolt assembling sleeve 21 due to gravity, as shown in fig. 5, an anti-falling ring 7 for limiting the falling of the bolt is arranged on the inner wall of the bolt assembling sleeve 21, preferably made of rubber, the bolt head of the bolt is extruded and embedded into the bolt assembling sleeve 21, the falling of the bolt is limited through the anti-falling ring 7, after the bolt is driven to move downwards to be connected with the nut, after the bolt assembling sleeve 21 contacts with a connecting side plate of the air pipe, the bolt rotates downwards, and the anti-falling ring 7 is extruded again to be separated from the bolt assembling sleeve 21.
The principle of the utility model is as follows: when the vertical air duct is assembled, the bolts and the nuts are assembled in the bolt assembling sleeve 21 and the nut assembling sleeve 22 in sequence, the bolts are vertically limited through the falling-preventing rings 7, and then the whole bolts extend into the connecting holes of the air duct from the position between the air duct and the side wall of the vertical shaft, so that the bolts correspond to the upper sides of the connecting holes, and the nuts correspond to the lower sides of the connecting holes;
the horizontal tube 43 is then held in one hand, the horizontal rod 6 is driven to rotate in the other hand (a hand-held electric drill can be preferably assembled at the outer end of the horizontal rod 6 to provide automatic rotation driving), the deformation rod 5 and the driving head 3 are driven to rotate, and meanwhile the horizontal rod 6 is driven to the inner side of the horizontal tube 43 to drive the bolt to pass through the connecting hole to be matched and fastened with the nut. After the connection of the bolt and the nut is completed, the horizontal rod 6 is pulled reversely, so that the driving head 3 is separated from the top end of the bolt, and then the horizontal pipe 43 slightly shakes downwards to separate the nut from the nut assembling sleeve 22, so that the whole tool can be separated from the bolt and the nut, and the tool is taken out from the side wall of the air pipe and the vertical shaft to fasten the next connecting hole.
