[technical field]
The utility model relates to the seal arrangement technical field, specifically a kind of quick fastening device.
[background technique]
At present, if two bearers will be fixed up, mode commonly used has two kinds, and a kind of is to adopt bolt, and another kind is to adopt elastic collar to fix.When adopting bolt, owing to need to consider the sealing of bolt connection part pressure penetration hole, thereby the structure more complicated; If adopting elastic collar fixes, when part bigger, bearing pressure is than higher part, in order to make elastic collar have enough intensity, then the size of elastic collar needs enough big, and elastic collar is oversize, and installation and removal will be used special tool, thereby the operation of installation and removal is all required great effort very much.
[model utility content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of quick fastening device is provided, solved the problem of the seal structure complex of pressure penetration hole when adopting bolt to connect, and the problem of adopt big elastic collar time installation and removal difficulty, and operation is very simple, convenient.
Design a kind of quick fastening device for achieving the above object, comprise body, coning sleeve, steel ball, elastic collar, inserting member;
Described inner body wall is provided with a groove and a carrying conical surface;
Described coning sleeve outer wall lower end is provided with the conical surface one, and the inwall upper end is provided with internal thread, and the internal thread below is provided with a sipes, and coning sleeve is provided with the mounting hole of the steel ball of packing into, mounting hole sealing after steel ball is packed into, and mounting hole and sipes connect;
Described elastic collar inwall is provided with the conical surface two, and the conical surface two is complementary with the conical surface one of coning sleeve, and the width of elastic collar height and body inside groove is complementary;
Described inserting member outer wall top is provided with outside thread, the internal thread of outside thread and coning sleeve is complementary, the outside thread below is provided with a groove, be provided with a circle steel ball between the sipes of groove and coning sleeve, inserting member outer wall bottom is provided with a step surface and one and puts the conical surface, and the carrying conical surface that seat is put the conical surface and body is complementary.
Described mounting hole is a tapped hole, and described steel ball is packed the back mounting hole into by the plug screw shutoff.
Described mounting hole is arranged with two along the coning sleeve center.
Described mounting hole is arranged on the bottom of sipes, and the bottom of described mounting hole and sipes connects.
The degree of depth of described sipes, groove is all identical with the steel ball radius.
The utility model is compared with prior art, novel structure, simple, reasonable in design, by from the tapped hole of coning sleeve, pouring into the steel ball of some, make to be provided with a circle steel ball between the groove of the sipes of coning sleeve and inserting member, and with plug screw with the tapped hole shutoff, thereby after mounted inserting member and assembly thereof were packed the body endoporus into, when with instrument rotation inserting member, coning sleeve was not along with the inserting member rotation, but only move down, reduced frictional force; The effect of steel ball is to have guaranteed coning sleeve when being subjected to the active force of elastic collar, the gap of coning sleeve and the non-threaded joint of inserting member, thus reduced frictional force; During dismounting, only need the derotation screw thread, the inner conical surface of coning sleeve and elastic collar just breaks away from, elastic collar shrinks, thereby elastic collar spins off in intrinsic groove, body can be removed from inserting member, operation is very simple, convenient, and the reliability height is worthy of popularization.

[embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As accompanying drawing 1 to shown in the accompanying drawing 6, the utility model comprises: body 1, coning sleeve 2, steel ball 3, elastic collar 4, inserting member 5, inner body wall is provided with a groove 7 and a carrying conical surface 8, coning sleeve outer wall lower end is provided with the conical surface 1, coning sleeve inwall upper end is provided with internal thread 10, coning sleeve inwall internal thread below is provided with a sipes 11, the depth dimensions of sipes is identical with the radius size of steel ball, coning sleeve is provided with the mounting hole 12 of the steel ball of packing into, mounting hole sealing after steel ball is packed into, this mounting hole is a tapped hole, steel ball is packed the back mounting hole into by plug screw 6 shutoff, tapped hole is arranged with two along the coning sleeve center, and mounting hole is arranged on the bottom of sipes, the bottom of mounting hole and sipes connects, the elastic collar inwall is provided with the conical surface 2 13, this conical surface two is complementary with the conical surface one of coning sleeve, the width of elastic collar height and body inside groove is complementary, the circumference of elastic collar cuts away a part, inserting member outer wall top is provided with outside thread 14, the internal thread specification of this externally threaded specification and coning sleeve is complementary, inserting member outer wall outside thread below is provided with a groove 15, the depth dimensions of groove is identical with the radius size of steel ball, be provided with a circle steel ball between the sipes of this groove and coning sleeve, inserting member outer wall bottom is provided with a step surface 16 and one and puts the conical surface 17, the carrying conical surface that seat is put the conical surface and body is complementary, the effect of steel ball is to guarantee coning sleeve when being subjected to the active force of elastic collar, and the gap of coning sleeve and the non-threaded joint of inserting member is to reduce frictional force.
