Abstract
The utility model discloses a connecting mechanism used for connecting first and second objects respectively provided with a connecting hole, which comprises a bolt and a nut. The bolt is sleeved with a steel sleeve gasket and the steel sleeve gasket is sleeved with an elastic gasket. One end of the steel sleeve gasket is provided with a first gasket and the other end of the steel sleeve gasket is provided with a second gasket. Due to the adoption of the connecting mechanism, the clamping torque is ensured to be provided, while objects to be connected are protected from being damaged by the overlarge clamping torque.
Description
Technical field
The utility model relates to the connection set technical field, specifically a kind ofly connects the bindiny mechanism that two articles provides clamping force protection simultaneously, particularly is applicable to being connected of locomotive vehicle-mounted antenna housing and mounting bracket.
Background technique
Along with the development of high-speed railway, BTM unit (XPNDR Transponder information receiving module and car antenna) will be promoted installation on the different model locomotive.The existing operating locomotive great majority of China do not have the mounting point of special car antenna, can only be installed on the locomotive through mounting bracket.The car antenna of installing at present; All be cooperate with high-strength bolt directly that execute must firm lock nut, car antenna and car antenna mounting bracket directly be fastened together that this kind installation method is owing to executing and must firm lock nut requirement must being used with corresponding high-strength bolt; And the clamping torque that reaches defined just can play locking purpose; Because the car antenna housing is nonmetallic material,, can cause near the interior tissue of car antenna housing bolt hole to be destroyed if clamping force is excessive; Phenomenons such as crackle, fracture occur, brought hidden danger for the normal operation of locomotive.
In view of the defective that the existing technology that the bindiny mechanism of car antenna is installed on locomotive at present exists, the design people actively studies and innovates, and to found a kind of bindiny mechanism, is also protected connecting fastening object when making connection fastening.Be specially adapted to being connected of locomotive vehicle-mounted antenna housing and mounting bracket, further protected car antenna itself not impaired, thereby guaranteed the security of operation of locomotive.
The model utility content
In order to solve the problems referred to above that exist in the existing technology, the utility model provides a kind of bindiny mechanism.The bindiny mechanism of the utility model is guaranteeing that connection is also played a protective role to connecting object in fastening.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
Bindiny mechanism is used to connect first object and second object that have attachment hole respectively, and said bindiny mechanism comprises screw bolt and nut; Be with the steel spacer on the bolt; Be with elastic washer on the steel spacer, an end of steel spacer is provided with first packing ring, and the other end is provided with second packing ring.
Further, said steel spacer passes the attachment hole of second object, and first packing ring is located between first object and second object, and said elastic washer is located at second packing ring, one side.
Further, said elastic washer is a polytetrafluoroethylene gasket.
Compared with prior art, the beneficial effect of the utility model is:
1, bindiny mechanism's compact structure of the utility model is simple and practical.
2, the bindiny mechanism of the utility model can also play a protective role to being connected object, especially to the easily vulnerable object of locomotive vehicle-mounted antenna casing and so under the situation that satisfies the requirement execute clamping torque that must firm nut.
3, the bindiny mechanism of the utility model is ageing-resistant, corrosion-resistant, long service life.
Description of drawings
Fig. 1 cuts open figure for the structure of the user mode of the bindiny mechanism of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, but not as the qualification to the utility model.
Fig. 1 cuts open figure for the structure of the user mode of the bindiny mechanism of the utility model.As shown in Figure 1; Bindiny mechanism; Be used to connect first object 6 and second object 8 that have attachment hole respectively, said bindiny mechanism comprises bolt 7, nut 1, steel spacer 4, elastic washer 3, first packing ring 5 and second packing ring 2, and steel spacer 4 passes the attachment hole of second object 8; Elastic washer 3 is placed on the steel spacer 4, and first packing ring 5 and second packing ring 2 are located at the two ends of steel spacer 4 respectively.Bolt 7 passes first object 6, first packing ring 5, steel spacer 4 and second packing ring 2, and is fastening through nut 1.Wherein nut 1 must firm nut for executing.Elastic washer 3 can be located at first packing ring, 5 one sides, also can be located at second packing ring, 2 one sides.First packing ring 5 is a plain washer.Second packing ring 2 is a large washer.Elastic washer 3 is a polytetrafluoroethylene gasket.
Certainly, the steel spacer also can pass first object and second object simultaneously and then elastic washer is set and first packing ring and second packing ring.Can both play a protective role to first object and second object like this.
Below in conjunction with Fig. 1 the installation and the working principle of the bindiny mechanism of the utility model are explained, so that understand the utility model better.
Install
Working principle:
With the bindiny mechanism of the utility model second object and first object are pressed the shown position installing and locating when pressing shown position; And after by the moment of regulation nut 1 (execute must firm nut) being tightened, the clamping force that between bolt 7 and nut 1 (execute must firm nut), be produced is exactly certain.If select the length of suitable steel spacer 4 and the thickness of elastic washer 3, just can this clamping force be decomposed into two suitable component, make it satisfy location and clamping simultaneously, and avoid damaging by the connection object because of clamping force is excessive.
Above embodiment is merely the exemplary embodiment of the utility model, is not used in restriction the utility model, and the protection domain of the utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in the essence and protection domain of the utility model, this modification or be equal to replacement and also should be regarded as dropping in the protection domain of the utility model.
