Abstract

The invention discloses a thermoregulation handle structure of a constant temperature faucet, which is mainly comprises a faucet body, a constant temperature mandrel rod, a handle, a spring, a joint, a setscrew and a closing ring, wherein the constant temperature mandrel rod, the handle, the spring, the joint, the setscrew and the closing ring are arranged at one end of the faucet body. The handle and the joint are in clearance fit by a spline gear A, and the spring is arranged between the handle and the joint; the closing ring is provided with three shifts of an upper temperature limit shift D, a 38 DEG C shift C and a lower temperature limit shift E, and the three shifts form a thermoregulation and burn-proof structure; and a shift device B which rotates along the rotation of the handle is arranged on the corresponding handle. The invention changes that the prior handle can realize temperate regulation by adding a button or a toggle, and the handle with the structure can move along the axial direction of the constant temperature mandrel rod. Simultaneously, the handle is rotated, and the constant temperature mandrel rod is also rotated. The thermoregulation handle structure has convenient use because of only operating the handle instead of operating the button or the toggle. Simultaneously, the constant temperature faucet has the advantage of concise appearance. The thermoregulation handle structure can be widely applied to the faucet with thermostatic regulation.

Description

A kind of temperature-regulating handle structure of constant-temperature tap

Technical field:

The present invention relates to plumbing, particularly a kind of temperature-regulating handle structure of constant-temperature tap.

Background technique:

At present, traditional constant-temperature tap temperature-regulating handle structure feature all is the push button or the formula of transferring, and such temperature-regulating handle all has powerful and influential feature, is that a button or toggle are all arranged on the handle, as shown in Figure 1 and Figure 2.This device designs for anti-scald, if when rotating handles is regulated temperature, do not use button or toggle, 40 ° of the temperature that can surpass not set of temperature (also have be set at 38 °) so, when the needs higher temperature, just must press the button or push aside toggle, then could rotating handles obtain the higher temperature that needs, This move need act on two component, be handle and button (or toggle), operate very loaded down with trivial details.

Summary of the invention:

The temperature-regulating handle structure that the purpose of this invention is to provide a kind of constant-temperature tap does not have button or toggle on this temperature-regulating handle, when needs are heightened temperature, only need operating handle, and no longer operating button or toggle make operation easier.

The objective of the invention is to take following technological scheme to solve, a kind of temperature-regulating handle structure of constant-temperature tap, mainly form by faucet subject and the constant temperature mandrel rod, handle, spring, joint, set screw, the stop ring that are separately positioned on faucet subject one end, it is characterized in that: adopt key tooth A Spielpassung between described handle and the joint, place spring in the middle of handle and the joint; Stop ring is provided with three gears, is respectively temperature upper limit gear D, 38 ° of gear C, lowest temperature gear E, forms temperature adjustment and anti-scald structure by them; On corresponding handle, also be provided with the gear shifting device B that rotates with the handle action.

The temperature-regulating handle structure of above-mentioned a kind of constant-temperature tap, described key tooth A Spielpassung is can be that cylinder adds the key toothing, can cause the heterodont cooperating structure of handle along the central axis activity of joint 4 as long as can also be.

The temperature-regulating handle structure of above-mentioned described a kind of constant-temperature tap, described joint and handle are integrative-structures, the motion on the axis of mandrel rod is can pass through by handle relatively, mandrel rod, the structure that the spring three constitutes realizes.

The temperature-regulating handle structure of above-mentioned a kind of constant-temperature tap, described spring can be tape measures, and memory alloy, cylinder, oil cylinder etc. have the part of replying original state trend to constitute.

The temperature-regulating handle structure of above-mentioned a kind of constant-temperature tap, described gear shifting device B moves with handle, and gear shifting device B and handle are integral structures.

The temperature-regulating handle structure of above-mentioned a kind of constant-temperature tap is a split-type structural between described gear shifting device B and the handle.

The present invention compared with prior art, changed conventional grip and need add the function that button or toggle could be realized temperature adjustment, the constant-temperature tap handle of this structure no longer needs button or toggle, and handle can move on constant temperature mandrel rod axial direction, the while rotating handles, the constant temperature mandrel rod is rotation and then.Because the present invention only needs operating handle in operation, no longer therefore operating button or toggle use easier.The outward appearance of constant-temperature tap is also more succinct simultaneously.Can be widely used in having on the thermostatically controlled tap handle.

Below in conjunction with accompanying drawing the present invention is illustrated:

Fig. 5 is that temperature-regulating handle of the present invention is transferred to the back position view;

Fig. 6 is a schematic representation of being transferred to the high temperature position after temperature-regulating handle of the present invention is extracted;

Embodiment:

As shown in Figure 1 and Figure 2: the structural representation that adds button or toggle for conventional grip, 7 is button or toggle, when needs are regulated temperature, must press the button or push aside toggle, then could rotating handles obtain the temperature that needs, This move need act on two component, i.e. handle and button or toggle.

As shown in Figure 3, this temperature-regulating handle structure comprises: constant temperature mandrel rod 1, handle 2, spring 3, joint 4, set screw 5, stop ring 6.Joint 4 screw 5 that is fixed is locked on the constant temperature mandrel rod 1, cooperates by the key backlash between handle 2 and the joint 4, and handle 2 can move horizontally on the key tooth A of joint 4, places springs 3 in the middle of handle 2 and the joint 4.Being provided with three gears on the stop ring 6, is respectively temperature upper limit gear D, 38 ° of gear C, lowest temperature gear E, also is provided with gear shifting device B on the corresponding handle 2, and they have formed temperature adjustment and anti-scald structure.

The principle of work and power of this temperature-regulating handle structure is as follows: suppose that before handle 2 temperature adjustments be 38 ° of positions, as Fig. 7, when needs are lower than 38 ° of temperature, handle 2 turns clockwise, when the gear shifting device B on the handle 2 is stopped by the lowest temperature gear E on the stop ring 6, handle 2 rotations are stopped, and temperature arrives minimum; Be rotated counterclockwise handle 2 this moment, regulates temperature and raise, and when the gear shifting device B on the handle 2 was stopped by 38 ° of gear C on the stop ring 6, handle 2 rotations were stopped, and temperature reaches 38 ° of the positions of anti-scald; When needs are higher than 38 ° of temperature, the handle level need be pulled out to the right, this moment, gear shifting device B crossed 38 ° of gear C, handle 2 can continue to be rotated counterclockwise then, when the gear shifting device B on the handle 2 is stopped by the temperature upper limit gear D on the stop ring 6, handle 2 rotations are stopped, and temperature arrives peak; The handle 2 that turns clockwise was regulated temperature and was reduced this moment, and when arriving 38 ° of gear C, because the effect of spring 3, handle 2 recovers left to put in place automatically, this moment handle 2 again can only 38 ° adjustment back and forth between gear C and the lowest temperature gear E.
