Abstract
The utility model relates to the automobile tire pressure monitoring system projector mounting structure of the tight screw torsion of a kind of controlled lockmaking.Described structure comprises auto-tire valve, the launcher shell be installed together with tire tube valve, lock screw, in the inner free air diffuser of tire tube valve, be provided with a limiting section, gos deep into the degree of depth of tire tube valve during for controlling lock screw locking projector housing.Conformability to the locking torsion that launcher shell produces when the setting of this limiting section ensure that different personnel's tighten the screws, prevent from causing projector housing failure because torsion is excessive, prevent from causing because torsion is too small projector housing to be connected the problem of loosening with tire tube valve simultaneously.
Description
Technical field
The utility model relates to a kind of automobile tire pressure monitoring system projector mounting structure, specifically refers to the automobile tire pressure monitoring system projector mounting structure of the tight screw torsion of a kind of controlled lockmaking.
Background technology
In existing automobile tire pressure monitoring system, connected the projector of projector housing and tire tube valve by lock screw.During installation, installation personnel spanner is needed to lock connecting screw.But tighten this screw with great torsion, the dynamics that different installation personnels uses is all different, and the individual feel generally with installation personnel controls.Like this, there is great randomness when mounted in the coupling mechanism force of connecting screw.From the angle of technology, the dynamics of this connecting screw controls to be very important.Dynamics is too large, and easily cause the crack damage of housing, dynamics is too little, projector housing can be caused to be connected with tire tube valve and loosen and final Joint failure.
Utility model content
For the shortcoming of prior art, the projector of lock screw locking torsion when the purpose of this utility model is to provide a kind of installation, can be controlled easily and reliably.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of automobile tire pressure monitoring system projector mounting structure, comprise tire tube valve, by the projector that lock screw and tire tube valve are installed together, limiting section is provided with in the inner free air diffuser of tire tube valve, when using lock screw to be connected with tire tube valve by launcher shell to lock, lock screw head just props up described spacing dress portion.
Preferably, described limiting section is be located at the round platform that tire tube valve inwall inwardly gives prominence to, and the internal diameter size of round platform is less than the outside dimension of lock screw.
The utility model by arranging spacing round platform in the inner free air diffuser of projector tire tube valve, the degree of depth is screwed in order to what limit lock screw, no matter anyone installs, the locking torsion applied launcher shell during lock screw locking all can be identical, as long as set the position of limiting section, installation personnel just can judge whether locking easily, efficient and convenient, greatly can improve installation effectiveness.
Accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
Fig. 2 is part A enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, mounting structure described in the utility model is used in the installation of projector 10 and tire tube valve 20 in automobile tire pressure monitoring system, and the two adopts lock screw 30 to be installed together.In the inside free air diffuser of tire tube valve 20, when lock screw 30 is locked, the position at head place is provided with a round platform 21.This round platform 21 is directly inwardly outstanding at the inwall of tire tube valve 20, and its round platform is empty internal is still free air diffuser, and the outside dimension that round platform internal diameter size is less than lock screw advances to stop screw.
When projector is installed, as long as installation personnel constantly tightens lock screw, until screw head end contact is to stopping into round platform 21 in tire tube valve.Namely in figure below, constantly tighten lock screw 30, along with the continuous advance of screw, the value of a is more and more less, until stop when being zero.Because tire tube valve there is a round platform exceeding screw external diameter, frustum cone height is h, and when a is zero, lock screw is by the stop of round platform, even if torsion continues to increase, lock screw can not move on.The pressure of lock screw to projector housing also reaches maxim thus, this ensures that theres projector housing can not cause projector housing crack damage because torsion increases, protects housing well.Each installation personnel is when installing projector, and all only lock screw need be tightened to the position that a value is zero, even if so different personnel install, the actual coupling mechanism force that housing is subject to is still identical.Like this, when just preventing different personnel to install, coupling mechanism force is too small and cause connecting the phenomenon loosened, and also prevent different personnel when installing, coupling mechanism force exists the phenomenon of randomness simultaneously.
During concrete enforcement, according to the needs without projector, the amount of compression of projector housing as required can control the height that stops into round platform and position when designing, the principle of realization and upper together.
Claims (2)
1. an automobile tire pressure monitoring system projector mounting structure, comprise tire tube valve, by the projector that lock screw and tire tube valve are installed together, it is characterized in that: in the inner free air diffuser of tire tube valve, be provided with limiting section, when using lock screw to be connected with tire tube valve by launcher shell to lock, lock screw head just props up described spacing dress portion.
2. automobile tire pressure monitoring system projector mounting structure according to claim 1, is characterized in that: described limiting section is be located at the round platform that tire tube valve inwall inwardly gives prominence to, and the internal diameter size of round platform is less than the outside dimension of lock screw.
