Embodiment
Be depicted as a kind of ring-type temperature measuring equipment that has auto-lock function disclosed by the invention like Fig. 1,2 and 3, include ring support 1, pcb board 2, temperature sensor 3 and be positioned at the self-locking device 50 of said temperature sensor 3 opposites.For realizing reliable locking, according to 3 equilibrium principles, embodiments of the invention have adopted two self-locking devices 50.The temperature sensor 3 that is positioned on ring support 1 inner ring surface 13 is arranged on the pcb board 2; Said pcb board is positioned on the said ring support 1; And be fixed on the ring support 1 through securing cover plate 4; So that temperature sensor 3 is fastened on the inner ring surface 13, avoids temperature sensor 3 to occur loosening and influence the accuracy of thermometric.
Said ring support 1 is provided with axial slide 12 and threaded hole 14 vertically; Radially be provided with the radial groove 11 that extends to ring support 1 inner ring surface 13; Axial slide 12 is arranged on an axial side of radial groove 11; Threaded hole 14 is arranged on the axial opposite side of radial groove 11, and axial slide 12 is communicated with radial groove 11 respectively with threaded hole 14.Said self-locking device 50 comprises and is arranged in the radial groove 11 radial slider 51 of radially sliding, is arranged on the axial slider 52 that slides vertically in the axial slide 12 and screws with threaded hole 14 and be connected and drive axial slider 52 Self-locking screw 53 in axial sliding; Axial slide 12 is on the axial line of said threaded hole 14; And on axial slider 52, be provided with axial hole 522; So that passing axial hole 522, said Self-locking screw 53 is connected with said threaded hole 14; Self-locking screw 53 can contact with axial slider 52 through the flange face on it 531 and be connected simultaneously; Be convenient to Self-locking screw 53 with process that screwing of threaded hole 14 is connected in, driving axial slide block 52 chute 12 vertically slides at the axial direction of said ring support 1.In other embodiment, axial slide 12 and threaded hole 14 can be arranged on the same side position of radial groove 11, and Self-locking screw 53 passes axial slider 52 actions that drive threaded hole 14 belows behind the threaded hole 14 again.Certainly can also make the slot to make way or the equivalent structure that supply Self-locking screw to pass on the axial slider 52 and replace axial hole 522, equally also can achieve the above object, no longer do detailed description at this.
The present invention simultaneously on said radial slider 51, also be provided with one with the driving consistent driven inclined-plane 511 of 521 slopes, inclined-plane; So that increase the surface of contact between axial slider 52 and the radial slider 51; Make that the suffered driving force on the radial slider 51 is steadily balanced more; Thereby it is more smooth and easy reliable to slide, and people are more convenient to operate flexibly.
As shown in Figure 4, the synoptic diagram when being unlocked for the present invention, this moment is for making things convenient for the present invention and columned testee 6 to be sleeved on one smoothly; Described ring support 1 is when original state, and the diameter of its inner ring surface 13 must be greater than the external diameter of testee 6, so radial slider 51 in a state of nature; Slide, therefore between the temperature sensor 3 of opposite and testee 6, do not have the effect of external force, possibly be in contact condition between them to the radial center of ring support 1; Also possibly there is gap A; Can't realize reliable connection in a word,, not accomplish accurate thermometric at all so satisfied not the precondition of thermometric.It can also be seen that simultaneously owing to be used to protect the existence of the protective sleeve 61 of testee 6; Make ring support 1 very little in the space of radial direction; There are not enough spaces that it is carried out fixing operation; Therefore also can only lock it, axially screw operation so Self-locking screw of the present invention can only be along said ring support 1 at axial direction.
As shown in Figure 5; Synoptic diagram when being in locking state for the present invention; This moment is owing to screw under the effect of locking at Self-locking screw 53, drive axial slider 52 vertically chute 12 along the axis direction of ring support 1 move and drive simultaneously radial slider 51 radially chute 11 to the axe movement of said ring support 1 until propping up testee 6 and stop the action that screws of Self-locking screw 53 tightly.Be not difficult to find out; The ring support 1 of this moment moves relative to the direction of testee 6 to self-locking device 50 positions; Make and between the temperature sensor 3 of ring support 1 axle center opposite and testee 6, just be in the state of fitting tightly; And gap A is also moved to an opposed side of said temperature sensor 3, thereby has realized that 3 pairs of testees of temperature sensor 6 carry out promptly accurately measuring reliably again the purpose of temperature.
Certainly when the diameter of testee hour, the present invention can only adopt the self-locking device 50 just can the satisfied temperature sensor and the fitting tightly of testee, and realizes reliable thermometric, its operating process will not given unnecessary details at this as previously mentioned one by one.
This explanation is only detailed case study on implementation of the present invention and is explained that though it has certain singularity on form and structure, these are special only to be in order to describe and to explain the present invention, can't having influence on any restriction of the present invention.Above-mentioned listed concrete implementation is nonrestrictive, to one skilled in the art, is not departing from the scope of the invention, and various improvement and the variation carried out all belong to protection scope of the present invention.
