Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 2 is the schematic representation of interconnective vehicle frame and wheel carrier among the present invention.As shown in Figure 2, bolt connecting device 200 of the present invention is used for wheel carrier 400 is detachably connected to vehicle frame 300.Vehicle frame 300 and wheel carrier 400 wherein one be provided with fixing column, another person is provided with the fixed cover that inserts for fixing column, and bolt connecting device 200 is fixedly connected on outside the fixed cover.In illustrated embodiment, fixing column 401 is arranged on the wheel carrier 400, and fixed cover 301 is arranged on the side of vehicle frame 300.Wherein fixing column 401 is cylindrical, and fixed cover 301 is cylindric.Those skilled in the art person can understand, and fixing column 401 can be other shape, polygonal for example, and fixed cover 301 also can be arranged to corresponding shape.
Fig. 3 is the partial enlarged drawing of Fig. 2, shows bolt connecting device 200.With reference to Fig. 3, this bolt connecting device 200 comprises the tubular guide pin bushing 201 of both ends open, and first end of this tubular guide pin bushing 201 is welded on outside the fixed cover 301, and second end has outside thread 202.This bolt connecting device 200 also comprises latch 203 and the latch cap 206 that cooperates with the outside thread 202 of second end of tubular guide pin bushing 201 by internal thread.This latch cap 206 is provided with the hole of passing through for latch 203.When latch cap 206 for latches 203 by and when cooperating with tubular guide pin bushing 201, form the inner chamber that seals between the two.It should be noted that this latch cap 206 also can be considered as one with tubular guide pin bushing 201, form tubular bolt sleeve, this tubular bolt sleeve one end opening and with fixed cover 301 welding, the other end sealing and have the hole of passing through for latch 203.
This latch 203 is roughly L-shaped, comprises orthogonal latch main body 204 and handle 205.On fixed cover 301 and fixing column 401, be respectively arranged with for the laterally inserted hinge last 302,402 of latch 203, when fixing column 401 inserted fixed covers 301, hinge last 302,402 was in alignment with each other.Latch 203 is by latch cap 206, tubular guide pin bushing 201, and inserts hinge last 302,402, makes that fixed cover 301 and fixing column 401 can not relative movement, thereby vehicle frame 300 is linked to each other with wheel carrier 400.
In tubular guide pin bushing 201, latch main body 204 middle parts of latch 203, be set with resilient key 207.This resilient key 207 radially runs through latch 203 along latch 203.This resilient key 207 is made of metal, and is hollow cylindrical, and has otch on sidewall, and this otch extends to the other end from an end of resilient key 207 vertically.On the latch 203, be provided with mounting hole, its diameter is slightly smaller than the external diameter of resilient key 207.During installation, clutch resilient key 207 with external force, its generation resiliently deformable, otch are diminished, behind the insertion mounting hole, cancel external force, resilient key restores to the original state, and can be fixed on the latch 203.
On latch 203, also be arranged with elastic element 208.This elastic element 208 can be a spring for example.One end of elastic element 208 is installed on the resilient key 207, and the other end is installed on the latch cap 206.When tubular guide pin bushing 201 and latch cap 206 are considered as the tubular bolt sleeve of one, to understand easily, the other end of elastic element 208 is installed in tubular bolt sleeve and has on the end in the hole of passing through for latch 203.When outside pulling latch 203, elastic element 208 can be compressed, and latch 203 withdraws from from fixed cover 301 and fixing column 401, makes vehicle frame 300 and wheel carrier 400 to be separated from each other.
With reference to Fig. 4-7, to locate better in order to make latch 203, the inside of tubular guide pin bushing 201, the close first end place are provided with internal projecting ring 209, and this internal projecting ring 209 makes tubular guide pin bushing 201 be divided into the different two-part of internal diameter, forms step surface 211 between two-part.On internal projecting ring 209, along radially being relatively set with two guide grooves 210.On step surface 211, along radially being relatively set with two standing grooves 212, the degree of depth of standing groove 212 is less than guide groove 210, and adjacent standing groove 212 and guide groove 210 be interval one predetermined angle on the circumferencial direction of internal projecting ring 209, preferred 90 degree of this angle.In illustrated embodiment, this guide groove 210 axially extends to first end of tubular guide pin bushing 201 always from step surface 211 along tubular guide pin bushing 201.
In conjunction with Fig. 3, when latch 203 inserted in fixed covers 301 and the fixing column 401, resilient key 207 cooperated with guide groove 210, and under the effect of elastic element 208, resilient key 207 is pushed against and away from step surface 211; When spurring latch 203 under external force, resilient key 207 extruding elastic elements 208 make it that resiliently deformable take place.When resilient key 207 moves to step surface 211 tops, latch 203 is rotated 90 degree, cancel external force afterwards, resilient key 207 is engaged with standing groove 212.This moment, latch 203 broke away from and the location with fixed cover 301, fixing column 401, made vehicle frame 300 and wheel carrier 400 to be separated from each other.
Compared with prior art, bolt connecting device 200 of the present invention has the following advantages:
1, tubular guide pin bushing 201 and fixed cover 301 welding, and with the latch cap 206 common enclosed spaces that pass through for latch 203 that form, even work light is used for the engineering construction scene, the blown sand slungshot can not enter, can resist the impact of blown sand slungshot, avoid influence elastic element 208;
2, resilient key 207 is with after standing groove 212 cooperates, and external force is cancelled, and resilient key 207 can not reset in resilience yet;
Even 3 are subjected to strong vibration, the resilient key 207 that is positioned at guide groove 210 or standing groove 212 can not be shifted easily yet, can avoid vibrating the harmful effect that brings.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
