Abstract
The utility model discloses a mechanical connecting and fastening device which comprises a fixed piece (1), a patch (2), a bolt (3) and a bolt (4), wherein protrusions (5) are arranged at one end of the fixed piece (1); hollow holes (6), which are the same in size and shape as the protrusions (5), are formed in the patch (2); the screw rod of the bolt (3) penetrates a hollow hole (8) in the patch (2), and is screwed in a threaded hole (7) in one end of the fixed piece (1), so that the fixed piece (1) and the head of the bolt (2) are tightly pressed on the patch (2); and moreover, the protrusions (5) are embedded into the hollow holes (6), so that the bolt (3), the fixed piece (1) and the patch (2) are kept in stable and firm relative positions. As the fixed piece and the patch are kept in relative positions, the mechanical connecting and fastening device has the advantages that impact of shake, friction and other factors on the bolts can be avoided effectively, and the possibilities of getting loose, moving and falling off of the bolts are greatly reduced, which improves the reliability and stability of the mechanical connecting and fastening device.
Description
Technical field
The utility model relates to connection and the fastening field of mechanical device, is specifically related to being connected and securing means of a kind of metal firmware and paster.
Background technique
At present mechanical connection and fastening mainly be by bolt firmware to be tightened on the object construction to realize.This mode is simple, but lacks reliability.It is stable that mechanical device requires to have firmly reaching of long-time many environment, and often need in actual applications to face for a long time various environment, involving vibrations, friction, corrosion etc.The mode that is tightened of bolt just produces easily loosening, displacement even comes off being in for a long time under these environment, need to check frequently, maintain and safeguard mechanical device.The such stability of mechanical device, all there is serious hidden danger in reliability and safety.
The model utility content
This practical new purpose is in order to overcome the deficiencies in the prior art, provide a kind of reliable, be easy to safeguard, stable connection and the mechanical device of fastening structure can be provided under varying environment for a long time.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposals: comprise firmware, paster, bolt, bolt, an end of firmware has projection, and the openwork hole identical with the size of projection and shape arranged on the paster, and projection embeds in the openwork hole; Firmware has an end of projection that tapped hole is arranged simultaneously; Have on the paster with firmware on tapped hole size and the identical openwork hole of shape; Openwork hole on the paster is identical with the relative position of tapped hole with the relative position of openwork hole and projection; There is tapped hole the side of firmware, and tapped hole and tapped hole vertical connection.Firmware and paster are metal material.Firmware has an end of projection to press paster; The screw rod of bolt passes openwork hole and is anchored in the tapped hole, and the head of bolt presses paster; Bolton is in tapped hole, and the screw rod end of bolt vertically presses the screw rod of bolt.
Compared with prior art, the utlity model has significant advantage, be embodied as: adopt simultaneously bolton and projection to embed fastening mode the relative position of firmware and paster is remained unchanged, thereby effectively avoided the impact of the factors such as vibrations, friction on bolt, the possibility that greatly reduced bolt looseness, displacement, comes off.Thereby the reliability and stability of this mechanical connection and securing means have been improved.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further, is listed as for two example two, wherein:
Fig. 1 is the utility model embodiment 1 general structure schematic representation;
Fig. 2 is the plan view of the utility model embodiment 1 each several part assembly;
Fig. 3 is the plan view of the utility model embodiment 1 each several part assembly;
Fig. 4 is the utility model embodiment 2 general structure schematic representation;
Fig. 5 is the plan view of the utility model embodiment 2 each several part assembly;
Fig. 6 is the plan view of the utility model embodiment 2 each several part assembly.
Embodiment
Such as accompanying drawing 1 to Fig. 6, wherein, the 1st, firmware, the 2nd, paster, the 3rd, bolt, the 4th, bolt, the 5th, the projection, the 6th, openwork hole, the 7th, tapped hole, the 8th, openwork hole, the 9th, tapped hole.
As shown in Figures 2 and 3, among the embodiment 1, openwork hole 6 on the projection 5 of firmware 1 one ends and the relative position of tapped hole 7 and the paster is identical with the relative position of openwork hole 8, and projection 5 is identical with openwork hole 6 sizes and shape, and tapped hole 7 is identical with openwork hole 8 sizes and shape.Have an end of projection 5 to align in paster 2 and firmware 1 and be close to, projection 5 is embedded in the openwork hole 7, this moment, tapped hole 6 also coincide corresponding with openwork hole 8.The screw rod of bolt 3 is passed openwork hole 8 and screw in the tapped hole 7, make the head of firmware 1 and bolt 3 press paster 2 after screwing and form fastening structures.Again bolt 4 is screwed in the tapped hole 9 of firmwares 1 side, make the screw rod end of bolt 4 vertically press the screw rod of bolt 3 after screwing.So far, this mechanical connection and securing means connect to be finished, as shown in Figure 1.
As shown in Figure 5 and Figure 6, among the embodiment 2, projection 5 and the tapped hole 7 of firmware one end are structure as a whole, openwork hole 6 and openwork hole 8 on the paster 2 also are structure as a whole, and projection 5 is identical with size and the shape of openwork hole 8 formed integral body with openwork hole 6 with size and the shape of tapped hole 7 formed integral body.Have an end of projection 5 to align in paster 2 and firmware 1 and be close to, projection 5 is embedded in the openwork hole 7, this moment, tapped hole 6 also coincide corresponding with openwork hole 8.The screw rod of bolt 3 is passed openwork hole 8 and screw in the tapped hole 7, make the head of firmware 1 and bolt 3 press paster 2 after screwing and form fastening structures.Again bolt 4 is screwed in the tapped hole 9 of firmwares 1 side, make the screw rod end of bolt 4 vertically press the screw rod of bolt 3 after screwing.So far, this mechanical connection and securing means connect to be finished, as shown in Figure 4.
