Embodiment
Be depicted as the disclosed a kind of ring-type temperature measuring equipment with auto-lock function of the utility model such as 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 described temperature sensor 3 opposites.For realizing reliable locking, according to 3 equilibrium principles, embodiment of the present utility model has 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, described pcb board is positioned on the described ring support 1, and be fixed on the ring support 1 by 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 affect the accuracy of thermometric.
Described 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 and threaded hole 14 are communicated with radial groove 11 respectively.Described self-locking device 50 comprises and is arranged in the radial groove 11 radial slider 51 of radially sliding, be arranged in the axial slide 12 axial slider 52 that slides vertically and screw with threaded hole 14 and be connected and drive in axial sliding Self-locking screw 53 of axial slider 52, axial slide 12 is on the axial line of described threaded hole 14, and be provided with axial hole 522 at axial slider 52, so that passing axial hole 522, described Self-locking screw 53 is connected with described threaded hole 14, Self-locking screw 53 can contact with axial slider 52 by the flange face 531 on it 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 vertically chute 12 slides at the axial direction of described 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 again threaded hole 14 belows behind the threaded hole 14.Certainly can also make the slot to make way or the equivalent structure that pass for Self-locking screw on the axial slider 52 and replace axial hole 522, equally also can achieve the above object, no longer do detailed description at this.
Be provided with on the axial slider 52 to be connected on the radial slider 51 and be used for driving radial slider 51 to the driving inclined-plane 521 of ring support 1 inner ring surface 13 1 side shiftings, this drive inclined-plane 521 be convenient to axial slider 52 in the process of in axial direction sliding, order about radial slider 51 radially chute 11 slide to the radial center direction of described ring support 1.Described driving of the present utility model inclined-plane 521 acutangulates with the axial direction of ring support, be that slope is kept a constant, so that the distance that described axial slider 52 advances is kept an equal proportion constant with the distance that described radial slider 51 is slided, be convenient for people to when screwing Self-locking screw 53 can perception locking degree.
The utility model also is provided with a driven inclined-plane 511 consistent with driving inclined-plane 521 slopes on described radial slider 51 simultaneously, so that the surface of contact between increase axial slider 52 and the radial slider 51, so that the suffered driving force on the radial slider 51 is more balanced steadily, thereby it is more smooth and easy reliable to slide, and people are more convenient to operate flexibly.
As shown in Figure 4, synoptic diagram when being unlocked for the utility model, this moment is for making things convenient for the utility model and columned testee 6 to be sleeved on smoothly one, described ring support 1 is when original state, 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, do not slide to the radial center of ring support 1, therefore between the temperature sensor 3 of opposite and testee 6, there is not the effect of external force, may be in contact condition between them, also may have gap A, can't realize reliable connection in a word, so do not satisfy the precondition of thermometric, do not accomplish accurate thermometric at all.It can also be seen that simultaneously because for the protection of the existence of the protective sleeve 61 of testee 6; so that ring support 1 is very little in the space of radial direction; there are not enough spaces that it is fixed operation; therefore also can only lock it at axial direction, axially screw operation so Self-locking screw of the present utility model can only be along described ring support 1.
As shown in Figure 5, synoptic diagram when being in locking state for the utility model, 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 described 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, so that 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 also is moved to an opposed side of described temperature sensor 3, thereby has realized that 3 pairs of testees of temperature sensor 6 carry out namely accurately measuring reliably again the purpose of temperature.
Certainly when the diameter of testee hour, the utility model 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 one by one at this as previously mentioned.
This explanation is only described in detail case study on implementation of the present utility model and is illustrated, although it has certain singularity in form and structure, but these are special only to be in order to describe and to illustrate the utility model, can't having influence on any restriction of the present utility model.Above-mentioned listed specific implementation is nonrestrictive, and to one skilled in the art, within not departing from the utility model scope, the various modifications and variations of carrying out all belong to protection domain of the present utility model.
