Abstract
The utility model discloses a torque limited nut structure which comprises a nut body and a screwed seat which can be sleeved on the nut body in a rotatable mode for people to screw. The nut body is provided with an internal threaded hole and a limiting boss. An elastic rib which can abut against the limiting boss is formed on the screwed seat. The elastic rib goes over the limiting boss when torque on the screwed seat exceeds a preset value so that the screwed seat and the nut body are arranged in a sliding mode. When the torque on the screwed seat stressed by people exceeds the preset value, the elastic rib goes over the limiting boss. The screwed seat does not transmit the torque to the nut body if the screwed seat is continuously screwed, and therefore the torque limited nut structure has the advantages of being capable of preventing situations such as thread sliding and water tank cracking from happening and good in safety.
Description
Technical field
The utility model relates to the nut structure field, relates in particular a kind of limit torque nut structure, when torsion meets or exceeds when setting torsion, can realize overload protection.
Background technique
In the kitchen guarding field, often need to use nut, thereby play the effect of locking at present.Such as in inlet valve, it is usually all supporting locking nut, this locking nut is all generally to adopt the traditional type structure, namely be provided with an interior threaded hole, thereby can coordinate with the outside thread of inlet valve, when this locking nut of people's turn, by realizing outside thread and coordinating of interior threaded hole the locking to inlet valve.
But, in Consumer's actual using process, can there be the situation that has applied larger torsion unavoidably, so will cause the sliding tooth of screw thread, even cause water tank to ftracture and cause the problem such as radiator leak.
In view of this, the inventor furthers investigate for defects of the prior art, then has this case to produce.
The model utility content
The purpose of this utility model is to provide a kind of limit torque nut structure, exists and causes the sliding tooth of screw thread because applying larger torsion to solve prior art, even causes water tank to ftracture and causes the problem of radiator leak.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of limit torque nut structure, wherein, comprise nut body and rotatably be set on nut body and supply the seat that screws of people's turn, this nut body has interior threaded hole and positive stop lug boss, this screw be formed with on seat can be inconsistent with positive stop lug boss elastic bar, this elastic bar is crossed positive stop lug boss and is made to screw between seat and nut body and be the shape that skids when the torsion that screws seat surpasses predefined value.
Further, this nut body periphery also is formed with annular block edge, and this screws seat and supports on this annular block edge, and this positive stop lug boss is arranged on annular block edge.
Further, also be formed with the first inclined-plane on this positive stop lug boss, be formed with the second inclined-plane on this elastic bar, this first inclined-plane and the second inclined-plane are inconsistent in limit torque nut structure screw-in process.
Further, this screws also to be formed with on seat for move back tooth process restriction elastic bar deformation quantity in limit torque nut structure crosses the limit ribs of positive stop lug boss to prevent elastic bar, this limit ribs when torsion surpasses predefined value in screwing in the locking process and elastic bar divide the both sides that are located at positive stop lug boss.
Further, this screws and also is formed with operating handle on seat.
Further, be formed with annular groove on this nut body, this screws and is formed with on seat and can joins the annular rib that is connected with the annular groove card.
After adopting said structure, the utility model relates to a kind of limit torque nut structure, it is divided into whole nut nut body and screws two-part, people are when needs turn nut, this turn power will act on and screw on seat, be passed on nut body by elastic bar and positive stop lug boss again, make the interior threaded hole of nut body to produce the turn effect with the outside thread effect.
When in case people have surpassed predefined value to the torsion that screws seat, this elastic bar will be crossed positive stop lug boss, continue this moment turn this when screwing, this screws seat will can not be passed to nut body with torsion, so make to have avoided thread to skid and the generation of the situation such as water tank cracking.

Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As extremely shown in Figure 5 in Fig. 1, a kind of limit torque nut structure 100 that the utility model relates to, comprise nut body 1 and screw seat 2, this screws seat 2 and rotatably is set on nut body 1 for people's turn, particularly, as this screw the seat 2 and nut body 1 between a kind of mode that is rotatably connected, as shown in Figure 3 and Figure 4, be formed with annular groove 11 on this nut body 1, this screws and is formed with on seat 2 and can joins the annular rib 21 that is connected with annular groove 11 cards.
As extremely shown in Figure 5 in Fig. 1, this nut body 1 has interior threaded hole 12 and positive stop lug boss 13, this screw seat be formed with on 2 can be inconsistent with positive stop lug boss 13 elastic bar 22, this elastic bar 22 is crossed positive stop lug boss 13 when the torsion that screws seat 2 surpasses predefined value, thereby make to screw between seat 2 and nut body 1 and be the shape that skids, this predefined value specifically can be adjusted according to actual needs, such as realizing by a plurality of angles such as the overlapping portion height between change elastic bar 22 and positive stop lug boss 13 or change elastic bar 22 materials, specifically do not do restriction; In addition in the present embodiment, this positive stop lug boss 13 and elastic bar 22 are all a plurality of along circumferentially being set to.
Particularly, in the present embodiment, this nut body 1 periphery also is formed with annular block edge 14, and this screws seat 2 and supports on this annular block edge 14, and this positive stop lug boss 13 is arranged on annular block edge 14.In order to allow this elastic bar 22 can cross easily positive stop lug boss 13, also be formed with the first inclined-plane 131 on this positive stop lug boss 13, be formed with the second inclined-plane 221 on this elastic bar 22, this first inclined-plane 131 and the second inclined-plane 221 are inconsistent in limit torque nut structure 100 screw-in processes, please refer to illustrated in figures 1 and 2.
In order to prevent that this from screwing seat 2 and skid equally and torsion can't be passed to the situation of nut body 1 in whole limit torque nut structure 100 is in the process of moving back tooth, this screws on seat 2 and also is formed with limit ribs 23, this limit ribs 23 is in limit torque nut structure 100 is moved back the tooth process, be used for restriction elastic bar 22 deformation quantities, thereby prevent that elastic bar 22 from crossing positive stop lug boss 13, this limit ribs 23 when torsion surpasses predefined value in screwing in the locking process and elastic bar be located at the both sides of positive stop lug boss 13 in 22 minutes, please refer to shown in Figure 1.
Operate screwing seat 2 for the ease of people, this screws on seat 2 and also is formed with operating handle 24, and particularly, in the present embodiment, this operating handle 24 is spent two that arrange for being 180.
Like this, the utility model relates to a kind of limit torque nut structure 100, please refer to shown in Figure 6, it is to limit the concrete schematic diagram of using of torque nut structure 100, it is by being divided into whole nut nut body 1 and screwing seat 2 two-part, and people are when needs turn nut, and this turn power will act on and screw on seat 2, be passed on nut body 1 by elastic bar 22 and positive stop lug boss 13 again, make the interior threaded hole 12 of nut body 1 to produce the turn effect with the outside thread effect.
When in case people have surpassed predefined value to the torsion that screws seat 2, this elastic bar 22 will be crossed positive stop lug boss 13, this screwed seat at 2 o'clock to continue turn this moment, and this screws seat 2 will can not be passed to torsion nut body 1, so made to have avoided thread to skid and the generation of the situation such as water tank cracking.
