Abstract
The utility model discloses a screwed cap buckling type assembly structure which comprises a body and a screwed cap. An opening is arranged in the body. The screwed cap is embedded at the opening in a screwed connection mode. Clamp grooves are arranged in the periphery of the opening of the body and clamp teeth matched with the clamp grooves in a buckled mode are arranged in the outer rim of the screwed cap. Or the clamp teeth are arranged in the periphery of the opening of the body and the clamp grooves matched with the clamp teeth in a buckled mode are arranged in the outer rim of the screwed cap. The screwed cap buckling type assembly structure has the advantages that corresponding clamp teeth and the clamp grooves are arranged on a fittingly screwed position between the screwed cap and the body. The a user assembles the screwed cap, as long as the screwed cap is screwed tightly, the clamp teeth and the clamp grooves are fittingly matched so as to avoid that screwing is excessive or the screwed cap is not in place due to loosening.
Description
Technical field
This utility model relates to a kind of mechanical connecting structure, is specifically related to a kind of Novel rotary hat type assembly structure.
Background technology
Turncap formula assembly structure is daily a kind of assembling mode of often seeing, simply says exactly turncap to be engaged in an opening part of body by the mode that is spirally connected, and reaching the described opening of sealing, or realizes with described opening the effect that is tightly connected.
For example, in the portable insulin infusion device, injection tube (medicine-storing tube) main body is arranged in the housing of device, offers a pilot hole in the position of injection tube drug end on housing, this pilot hole place is used for infusion turncap of assembling, is provided with plug into hole and tube for transfusion on the infusion turncap.After infusion turncap and pilot hole are spirally connected, make the hole of plugging on turncap coordinate with the drug end seal of injection tube, the tube for transfusion that is connected with the hole of plugging into stretches out, and its end is used for connecting human body (diabetics).
Yet above-mentioned infusion turncap is only a conventional turncap, and namely only by the internal thread rotation tight fit at the external screw thread on turncap, pilot hole place, its defective is: the bad control of tightness during assembling, and heavy-handed user may the disposable position that rotates through, the damage apparatus; The user of have gentle hands may assemble again not in place, causes the problems such as the leakage that leaks air.
The utility model content
The purpose of this utility model is to address the deficiencies of the prior art, and a kind of novel turncap formula assembly structure is provided.The technical scheme that realizes above-mentioned purpose is as follows:
A kind of turncap buckle type assembling structure comprises body and turncap, is provided with opening on body, and turncap is embedded in described opening part in the mode of being spirally connected; It is characterized in that: described body offers draw-in groove at the periphery of opening, and described turncap outer rim is provided with the latch that can be clasped with described draw-in groove; Perhaps described body offers latch at the periphery of opening, and described turncap outer rim is provided with the draw-in groove that can be clasped with described latch.
As concrete technical scheme, described latch and draw-in groove are more than two, and equal angles interval setting.
As concrete technical scheme, described latch is arranged on the turncap outer rim via elastic arm, and elastic arm and turncap are one-body molded, arranges along the direction that turncap screws, and latch is positioned at outside free end of elastic arm.
As further technical scheme, described turncap top is provided with the turn-knob sheet.
As further technical scheme, described turncap inboard central authorities are provided with the hole of plugging into.
As further technical scheme, the central conduit that connects the described hole of plugging into that is provided with in the described turncap outside.
The beneficial effects of the utility model are: the position that just screws in turncap and body openings arranges corresponding latch and draw-in groove, like this when user assembled turncap, when turncap screwed, described latch and draw-in groove also coordinated just, avoided overtighten or crossed loose not in place.

The side view of the turncap that Fig. 2 provides for embodiment.
The top view at Fig. 3 provides for embodiment body openings place.
The top view at Fig. 4 provides for embodiment body openings place.
Fig. 5 provides the application exemplary plot of turncap for embodiment.
The specific embodiment
In conjunction with Fig. 1 and Fig. 3, the turncap buckle type assembling structure that the present embodiment provides comprises body 10 and turncap 20.
As shown in Figure 1, the concrete shape of body 10 is unrestricted, is provided with poroid opening 11 on an end of body 10, and opening 11 inwalls are provided with the screw thread that spins.Body 10 offers two draw-in grooves, 12, the two draw-in grooves 12 180 degree intervals that are separated by at the periphery of opening 11 and arranges, in conjunction with shown in Figure 2.
As shown in Figures 3 and 4, the bottom of turncap 20 is set to the section of spinning 21, and the top is set to turn-knob sheet 23, and spinning between section 21 and turn-knob sheet 23 is a rounded tabs 22.Rounded tabs 22 outer rims of turncap 20 are provided with two latches 25, latch 25 can be clasped with above-mentioned draw-in groove 12, this latch 25 is to be arranged on rounded tabs 22 outer rims of turncap 20 via elastic arm 26, elastic arm 26 is one-body molded with turncap, arrange along the direction that turncap screws, latch 25 is positioned at outside free end of elastic arm.
During cooperation, turncap 20 is embedded in opening 11 places of body 10 in the mode of being spirally connected, and when being screwed onto correct position, by chance latch 25 snaps in draw-in groove 12.
When the turncap buckle type assembling structure conduct that above-described embodiment provides is specifically used, can increase corresponding additional technical feature for practical situation.For example, when being used in the portable insulin infusion device, be provided with in turncap 20 inboard central authorities the hole (not shown) of plugging into, and 20 outside central authorities arrange the conduit 28 that connects the described hole of plugging at turncap, for be connected injection tube 40 connection cooperations with infusion device through a sealing ring 30, as shown in Figure 5.
Above embodiment is only for fully open unrestricted this utility model, for the simple replacement that can know without creative work, or the increase and decrease of constructed feature, should belong to the application scope of disclosure.For example, can be at the periphery of opening, latch to be set at body, in the turncap outer rim, draw-in groove is set; In addition, the number of latch and draw-in groove should not be restricted to two yet.
