Abstract
The utility model provides a be applied to nut locking device of photovoltaic connector or photovoltaic terminal box, includes connecting body, connecting body upper portion have the screw thread so that be connected with the nut, the outer wall of nut on have many sharp arriss, and the inner wall below and the connecting body of nut are connected one end, be provided with a plurality of sawtooth along the circumference of inner wall, a plurality of sawtooth are arranged neatly and just in time around the inner wall round, the both sides of every sawtooth form sawtooth inclined plane and sawtooth steep face respectively, the screw thread top on connecting body upper portion also be provided with the sawtooth inclined plane of sawtooth and sawtooth steep face matched with sawtooth two. Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: because set up sawtooth and sawtooth two on the screw thread of nut and connection body, long-term the use back, also difficult not hard up, the inclined plane and the steep face structure on the nut utilization sawtooth simultaneously for relatively light when screwing firmly, very difficult when unscrewing, the fastness is fine.
Description
Technical field
The utility model relates to photovoltaic connector and photovoltaic junction box, relates in particular to the nut anti-looseness device of photovoltaic connector and photovoltaic junction box.
Background technique
Along with people's life and the needs of producing; Photovoltaic panel has obtained application more and more widely in people's daily life; And photovoltaic panel is in use very high to the requirement of connection set (for example connector or connecting box), needs well to be electrically connected tightness, sealing and soundness.
Connector for photovoltaic panel or terminal box generally adopt connect-disconnect structure at present, and present connector and terminal box nut generally use ordinary construction, and be after long-term the use, loosening easily.Simultaneously at present on the market photovoltaic connector and terminal box nut becomes flexible naturally, free-handly just can unscrew nut, and soundness is relatively poor.
The model utility content
The purpose of the utility model is to provide a kind of and has overcome present connector and the terminal box nut generally uses ordinary construction, after long-term the use, and loosening easily problem.The problem that exists in the existing technologies such as simultaneously at present on the market photovoltaic connector and terminal box nut becomes flexible naturally, free-handly just can unscrew nut, and soundness is relatively poor.
For addressing the above problem, the technological scheme that the utility model is taked is:
A kind of nut anti-looseness device that is applied to photovoltaic connector or photovoltaic junction box; Comprise the connection body; There is screw thread on described connection body top so that be connected with nut, and many lug, nibs are arranged on the outer wall of described nut, and the inwall of nut below be connected body and connect an end; Circumference along inwall is provided with a plurality of sawtooth; A plurality of sawtooth marshallings and just in time around inwall one circle, the both sides of each sawtooth form sawtooth inclined-plane and the steep face of sawtooth respectively, the threaded tip on connection body top also is provided with the sawtooth two that matches with the sawtooth inclined-plane and the steep face of sawtooth of sawtooth.
The screw thread bottom of described connection body also is provided with loosens back-off.
The described back-off that loosens is symmetrically arranged with two along connecting the body periphery.
Adopt the beneficial effect that technique scheme produced to be: the utility model is applied to the nut anti-looseness device of photovoltaic connector or photovoltaic junction box, owing on nut and the screw thread that is connected body, be provided with sawtooth and sawtooth two, and for a long time after the use; Also be not easy to become flexible, simultaneously, nut utilizes sawtooth inclined-plane and the steep face of sawtooth on the sawtooth; Lighter when make twisting the jail, unusual difficulty when unscrewing can't free-handly be opened; Must use special tool, so the utility model soundness is fine.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model loosens back-off part-structure schematic representation;
Fig. 3 is the enlarged diagram of the utility model nut and body cross section when tightening.
Embodiment
Do in the face of the utility model down and describe in further detail:
Like Fig. 1, shown in 2; A kind of nut anti-looseness device that is applied to photovoltaic connector or photovoltaic junction box comprises connecting body 2 that connecting body 2 tops has screw thread so that be connected with nut 1; In the present embodiment; Connect body 2 belows and be symmetrically arranged with two locking levers 21, many lug, nibs 11 are arranged on the outer wall of nut 1, and the inwall of nut 1 below be connected body 2 connections one end; Circumference along inwall is provided with a plurality of sawtooth 12; A plurality of sawtooth 12 marshallings and just in time around inwall one circle, the both sides of each sawtooth 12 form sawtooth inclined-plane 13 and the steep face 14 of sawtooth, the threaded tip on described connection body 2 tops also are provided with the sawtooth 2 22 that sawtooth inclined-plane 13 and the steep face 14 of sawtooth match.The screw thread bottom that connects body 2 also is provided with loosens back-off 23.Be symmetrically arranged with two and loosen back-off 23 along connecting the body periphery.The edge that loosens back-off 23 forms naturally and loosens back-off inclined-plane 24.
Below again one say the utility model concrete utilization.
As shown in Figure 3; When the nut of the utility model is tightened; Sawtooth inclined-plane 13 is prone to slip under the elastic reaction of locking back-off inclined-plane 24 and locking back-off 23, can reach the result who easily tightens, and when nut is unscrewed; The steep face 14 of sawtooth coincide with locking back-off 23 and it is blocked, thereby nut can't be become flexible.
Claims (3)
1. nut anti-looseness device that is applied to photovoltaic connector or photovoltaic junction box; Comprise and connect body (2); There is screw thread on described connection body (2) top so that be connected with nut (1); It is characterized in that: many lug, nibs (11) are arranged on the outer wall of described nut (1); And the inwall of nut (1) below with is connected body (2) and connects an end, be provided with a plurality of sawtooth (12) along the circumference of inwall, a plurality of sawtooth (12) marshalling and just in time center on inwall one and enclose; The both sides of each sawtooth (12) form sawtooth inclined-plane (13) and the steep face of sawtooth (14) respectively, and the threaded tip on described connection body (2) top also is provided with the sawtooth two (22) that matches with the sawtooth inclined-plane (13) and the steep face of sawtooth (14) of sawtooth (12).
