Angle be the important evaluation index for determining tire wear and vehicle driving performance.In order to realize that multiple positions are used on testing stand
Move and angular transducer, in the case where motion and power is applied, corresponding displacement and angle become tire under measuring whole vehicle state
Change amount, is problem that survey engineer often is faced with.But tire is made up of elastic caoutchouc and complex-shaped wheel hub etc., nothing
Method is mounted directly sensor.
At present now, automobile tire is fixed with automobile brake disc or brake rim with least 4 bolt and nuts, by external
One mode of tire fixing nut clamping mechanism, in the case of being capable of achieving not dismount tire, car is fixed on by measurement sensor
On wheel, but generally complex structure, assemble and disassemble very inconvenient.
Utility model content
The utility model aims to provide one kind and is exclusively used in pick up lug nut retaining mechanism, and realization is not dismounting the feelings of tire
Under condition, tire fixing nut is clamped, so as to provide easy for installation to install measurement sensor.
Therefore, the technical scheme that is used of the utility model for：A kind of pick up lug nut retaining mechanism, including sleeve,
Elastic clamping cylinder, locking nut and outer connecting bolt, the elastic clamping cylinder include the mounting cylinder and spring cylinder that are integrally coaxially disposed,
The external diameter of the spring cylinder is more than the internal diameter of sleeve, and axially extending short slot is provided with spring cylinder, and elastic clamping cylinder is placed in
In sleeve, the left end back cover of mounting cylinder is simultaneously reached outside sleeve, and the termination of outer connecting bolt is placed in mounting cylinder, the bar portion of outer connecting bolt
Reach outside mounting cylinder left end bottom, the locking nut is sleeved on outside mounting cylinder and is threadedly coupled with mounting cylinder, and lock is turned to the right
Tight nut, promotes sleeve to move right so that spring cylinder is drawn in so as to by the nut check of pick up tire, the outer connecting bolt
Bar portion is set with nut for external sensor installing mechanism.
Used as the preferred of such scheme, the mounting cylinder is divided into the reduced diameter section of left end and the enlarged diameter section of right-hand member, locking
Nut is connected by the screw thread on reduced diameter section outer wall with mounting cylinder, and the enlarged diameter section is gradually increased with spring cylinder by diameter
Changeover portion be connected.
The beneficial effects of the utility model：Elastic clamping jacket casing is promoted by rotational lock nut and covered on lug nut
Cylinder is mobile, realizes lug nut being held elastic clamping cylinder tightly, and outer connecting bolt support screw cap is then used for external sensor fitting machine
Structure, sensor is then arranged on sensor attachment mechanism；The lug nut external diameter that the lug nut retaining mechanism can be locked is big
When the maximum inner diameter and locking nut that small spring cylinder when being screwed out completely by locking nut opens all are screwed in the minimum of spring cylinder
Footpath is determined, is often designed with tire fixing nut size according to picking-up vehicle, so that suitable for the picking-up vehicle tire commonly used
Fixing nut；The clamping of pick up tire fixing nut in the case where tire is not dismounted, can be quickly realized, is in pick up tire
Upper external other mechanisms provide fixed installation point, so as to realize the installation of sensor；Install empty with compact, occupancy simple for structure
Between small, cheap for manufacturing cost, easy to operate, dependable performance the features such as, be suitable to be widely popularized utilization.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is axonometric drawing of the present utility model.
Specific embodiment
Below by embodiment and with reference to accompanying drawing, the utility model is described in further detail：
With reference to shown in Fig. 1-Fig. 2, a kind of pick up lug nut retaining mechanism, mainly by sleeve 1, elastic clamping cylinder 2, lock
Tight nut 3 and outer connecting bolt 4 are constituted.
Elastic clamping cylinder 2 includes the mounting cylinder 2a and spring cylinder 2b that are integrally coaxially disposed, and the external diameter of spring cylinder 2b is more than set
The internal diameter of cylinder 1, and axially extending short slot 2c is provided with spring cylinder 2b.Elastic clamping cylinder 2 is biopsy cavity marker devices schematic diagram.
Elastic clamping cylinder 2 is placed in sleeve 1, and the left end back cover of mounting cylinder 2a is simultaneously reached outside sleeve 1.The end of outer connecting bolt 4
Head is placed in mounting cylinder 2a, and the bar portion of outer connecting bolt 4 is reached outside mounting cylinder 2a left ends bottom, is provided with mounting cylinder 2a left ends bottom
For the circular hole that the bar portion of outer connecting bolt 4 passes through.
Locking nut 3 is sleeved on outside mounting cylinder 2a and is threadedly coupled with mounting cylinder 2a, is provided with outside mounting cylinder 2a and lock
The external screw thread of the tight matching of nut 3.Preferably, mounting cylinder 2a points is the reduced diameter section and the enlarged diameter section of right-hand member of left end, locking screw
Female 3 are connected by the screw thread on reduced diameter section outer wall with mounting cylinder 2a；In addition, enlarged diameter section passes through diameter gradually with spring cylinder 2b
Increased changeover portion is connected, and facilitates sleeve 1 swimmingly to move right.
Turn locking nut 3 to the right, promote sleeve 1 to move right so that spring cylinder 2b is drawn in so as to by pick up tire
Nut check, the bar portion of outer connecting bolt 4 is set with nut for external sensor installing mechanism.
When using, elastic clamping cylinder 2 is enclosed within lug nut, promotes sleeve 1 to move by rotational lock nut 3, is realized
Elastic clamping cylinder 2 is held tightly lug nut, the support screw cap of outer connecting bolt 4 is then used for external sensor installing mechanism, sensor
Then it is arranged on sensor attachment mechanism；The lug nut external diameter size that the lug nut retaining mechanism can be locked is by locking screw
The minimum diameter institute of spring cylinder 2b when the maximum inner diameter and locking nut 3 that spring cylinder 2b opens when mother 3 screws out completely are all screwed in
Determine, often designed with tire fixing nut size according to picking-up vehicle, so that the picking-up vehicle tire suitable for commonly using is fixed
Nut.
