Abstract
The utility model relates to a fixing device with a U-shaped notch. The upper end surface of a U-shaped notch is provided with a circular concave table which is matched with a cylindrical head bolt which can effectively enhance the reliability of the fixing mode. When the cylindrical head bolt is screwed, a device can be fixed by the matching of the periphery of the concave table and a bolt head. The connection of a U-shaped notch support frame and the device can adopt the methods, such as riveting, screwing, welding, etc. The U-shaped notch support frame can also be integrated with a casing of the device. The U-shaped notch inserted fixing device with the concave table can bear the maximum external force which is reverse with an inserted direction is the friction force which is generated by positive pressure after a screw bolt is screwed. The fixing device with a U-shaped notch can not cause permitted shearing force of screw bolt destruction, and the quantity value of the back force is more than 10 times to the quantity value of the front force. The utility model has the advantages of easy structure processing and low technology cost.
Description
One, technical field
The utility model belongs to a kind of equipment fixing device for installing, especially is with U-shaped breach fixed support.
Two, background technique
A lot of equipment and fitting seat fixedly adopted the mode of fixing with the support inserting bolt of U-shaped breach, its installation steps are:
1. unscrew fixing bolt on the fitting seat;
2. the U-shaped notch alignment bolt of equipment mounting bracket is inserted;
3. bolt is tightened.
Present being seen U-shaped breach supporting structure is plane structure, after this kind equipment means of fixation utilizes bolt to screw, the friction that positive pressure produced makes the Normal plane location of equipment at bolt, if equipment is subjected to the external force opposite with direction of insertion and greater than friction, equipment will produce displacement along the direction of power, and it is fixing unreliable to cause.
Three, model utility content
The utility model purpose is: eliminate the above-mentioned defective of plane U-shaped breach support, improve reliability of fixation.
Technical solution of the present utility model is: be provided with a circular concave station in U-shaped breach upper-end surface, and be equipped with cylinder head bolt, improved the reliability of this kind means of fixation effectively.
The utility model processes circular concave station in the U-shaped breach upper-end surface of mounting bracket, makes cylinder head bolt fixing in this concave station.After cylinder head bolt screws in, utilize the cooperation of concave station periphery and bolt head, fixed equipment.U-shaped breach support and equipment be connected methods such as can taking riveting dress, spiral shell dress, welding, also can be made of one with device housings.
The beneficial effects of the utility model:
The maximum external force opposite with direction of insertion that the equipment of plane U-shaped breach plug-in mounting can bear is that bolt screws the frictional force that the back positive pressure produces.
The maximum external force opposite with direction of insertion that the equipment of the U-shaped breach plug-in mounting of band concave station can bear is that bolt screws the frictional force that the back positive pressure produces, and not causing bolt to destroy the shearing force that allows, the value of a back power is more than 10 times of value of last Xiang Li; And the easy processing of structure, the technology cost is low.

Fig. 3 mills out the supporting structure spare figure of a circular concave station for the utility model U-shaped breach upper-end surface
Cylinder head bolt 1, U-shaped breach upper-end surface mill out the support 2 of a circular concave station, fitting seat 3, equipment 4, circular concave station 5.
Five, embodiment
Fig. 1 is seen in the concrete application of the utility model on equipment.The structural member connection diagram is seen Fig. 1, and structural member figure sees Fig. 2-Fig. 3.As shown in the figure, process circular concave station in the U-shaped breach upper-end surface of mounting bracket, the socket cap of bolt embeds fixing in this concave station.After cylinder head bolt screws in, utilize the cooperation of concave station periphery and bolt head, the equipment displacement is produced constraint, improved the reliability of this kind means of fixation effectively.U-shaped breach support and equipment be connected methods such as can taking riveting dress, spiral shell dress, welding, also can be made of one with device housings.
The utility model structural member can be selected non-ferrous metal, ferrous metal and engineering plastics etc. for use, and required manufacturing equipment is milling machine, lathe, drilling machine, shearing machine, bending machine, as with engineering plastics and adopt integrated through injection molding to change into shape U-shaped breach support, then needs injection machine.
