Abstract
The utility model discloses a time delay valve draws cap anti loosening structure, include set screw, draw cap, cylindrical spring, pull rod, plastic washer, fixed seal rubber ring and valve body, pull rod one end and valve body internal connection, the other end extend the valve body outer and with draw cap threaded connection, plastic washer and fixed seal rubber ring all are located between pull rod and the valve body, cylindrical spring cup joints on the pull rod, and its both ends respectively butt plastic washer with draw the cap, set screw passes and draws the cap center to be connected with rod thread, the internal thread that draws the cap and set screw's external screw thread revolve to on the contrary. The internal thread that draws the cap is right tooth screw thread, set screw's external screw thread is left tooth screw thread. Its locking opposite direction who draws cap and set screw can restrict mutually, prevents to draw the cap to take off from the pull rod pine. The utility model discloses can be used to the design of bathroom utensil valve body.
Description
Technical field
This utility model relates to dispensing valve technical field, draws cap anti-loose structure particularly to a kind of time-delay valve.
Background technology
Time-delay valve generally includes pull bar, fixing screw and draws cap, described cap is drawn to have the first female thread, described pull bar includes installation end and fixing end, described installation end with draw that cap is fixing to be connected, the end face circle centre position of described installation end is provided with lock hole, described fixing screw is through drawing cap to threaded with lock hole, and the outer wall of described installation end is provided with first external screw thread suitable with drawing cap, is provided with second female thread suitable with fixing screw in described lock hole.Owing to its first external screw thread of existing pull bar and the second female thread are right thread, fixing screw easily occurs after a long time use and draws cap to get loose simultaneously.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of time-delay valve and draws cap anti-loose structure.
A kind of time-delay valve draws cap anti-loose structure, including fixing screw, draw cap, cylindrical spring, pull bar, plastic washer, fixing seal cushion rubber and valve body, described pull bar one end is connected with valve inner, the other end extends outside valve body and is connected with drawing cap thread, described plastic washer and fixing seal cushion rubber are respectively positioned between pull bar and valve body, described cylindrical spring is socketed on pull bar, and its two ends abut plastic washer respectively and draw cap, described fixing screw is connected with pull rod screw through La Mao center, described in draw the female thread of cap oppositely oriented with the external screw thread of fixing screw.
The female thread drawing cap described in the utility model is right thread, and the external screw thread of described fixing screw is left thread.
The utility model discloses a kind of time-delay valve and draw cap anti-loose structure, it draws cap in opposite direction with the locking of fixing screw, can limit mutually, prevents from drawing cap to get loose from pull bar.This utility model can be used for bathroom utensil valve design.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model rather than whole embodiment, and those skilled in the art is not on the premise of paying creative work, it is also possible to obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is view in full section of the present utility model.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of this utility model protection.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict.
As shown in Figure 1, a kind of time-delay valve draws cap anti-loose structure, including fixing screw 1, draw cap 2, cylindrical spring 3, pull bar 4, plastic washer 5, fixing seal cushion rubber 6 and valve body 7, described pull bar 4 one end is internal with valve body 7 to be connected, the other end extends outside valve body 7 and threadeds with drawing cap 2, described plastic washer 5 and fixing seal cushion rubber 6 are respectively positioned between pull bar 4 and valve body 7, described cylindrical spring 3 is socketed on pull bar 4, and its two ends abut plastic washer 5 respectively and draw cap 2, described fixing screw 1 is through drawing cap 2 center to threaded with pull bar 4, the described female thread drawing cap 2 is oppositely oriented with the external screw thread of fixing screw 1.
Be further used as preferred embodiment, described in draw the female thread of cap 2 be right thread, the external screw thread of described fixing screw 1 is left thread.Draw between cap 2 with pull bar 4 threaded be that right tooth is connected, fixing screw 1 is that the connection of left tooth is locked by drawing cap 2 endoporus to be connected with the female thread of pull bar 4；Oppositely oriented because of internal and external threads, when fixing screw 1 is connected with the female thread of pull bar 4 and to loosen, drawing the external screw thread closure between cap 2 and pull bar 4 is then locking state；Otherwise when loosening when drawing the external screw thread between cap 2 with pull bar 4 to be connected, the female thread closure of fixing screw 1 and 4 pull bar is then locking state；Utilize left tooth different with the rotation direction of right tooth (i.e. orthodontic and anti-tooth), play interlocking and limit, reach locking purpose.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the application claim limited range.
