Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Core of the present utility model is to provide a kind of protective cover, and this protective cover is easy to use, not easily injures operating personnel by a crashing object, and fail safe is high.Another core of the present utility model is to provide a kind of distribution box comprising above-mentioned protective cover, and this distribution box maintenance mode is easy, and fail safe is high.
Please refer to Fig. 1, Fig. 1 is the profile of the specific embodiment of protective cover provided by the utility model.
A kind of protective cover that the present embodiment provides, this protective cover is mainly arranged on end face or the side of distribution box, makes distribution box can switch-linear hybrid, and handled easily personnel check and keep in repair the device of distribution box inside.
Protective cover mainly comprises main lid 5 and window 2, main lid 5 is for being connected with distribution box body, main lid 5 is provided with inspection hole 6, window 2 is hinged by jointed shaft 3 with the inwall of inspection hole 6, with realize window 2 turning be arranged on inspection hole 6, operating personnel check the electrical equipment situation of inspection hole 6 inside by window 2, and can open window 2 by upset, realize the maintenance to the electrical equipment in inspection hole 6 and adjustment.The inwall of inspection hole 6 is provided with boss, boss is provided with clamping part, this clamping part be used for window 2 on be positioned at jointed shaft 3 side the first side wall carry out clamping support, sidewall is parallel with jointed shaft 3, to realize window 2 when jointed shaft 3 rotates and the connecting and fixing of clamping part.
The protective cover that the present embodiment provides in use, first lift groove 1 is upwards mentioned, and drive window 2 to rotate around jointed shaft 3, in rotary course, the first side wall contacts with clamping part and supports, and producing frictional force, the two relative position is fixed by frictional force therebetween, makes window 2 freely can not overturn downslide.The protective cover that the present embodiment provides in use, when window 2 rotates around jointed shaft 3 time, contacted with clamping part by the first side wall of the window 2 making rotation, and realize connecting and fixing, thus realize the fixing of window 2, that avoids window 2 freely overturns downslide.This protective cover can avoid the injury to distribution box body and operating personnel, and security performance is good, and long service life.
In a preferred implementation provided by the utility model, clamping part is the rigid disk 4 of bending, rigid disk 4 is arranged on the side near the first side wall on boss, and be positioned at the below of window 2, rigid disk 4 is protruding to the first side wall of window 2, for upset after the first side wall connect and fix.
The clamping part that the present embodiment provides is rigid disk 4, sheet-type device that this rigid disk 4 is bending, that have rigidity.Rigid disk 4 is positioned at below window 2, and the position of the first side wall of close above-mentioned window 2, for connecting and fixing with this first side wall.This rigid disk 4 has at least two bending sides, the base of bending and boss are by being welded to connect, kink, towards the first side wall, forms a leg-of-mutton rigid disk 4 be arranged on boss, and rigid disk 4 can carry out clamping support when the first side wall rotates around jointed shaft 3 to the first side wall.
When the first side wall rotates around jointed shaft 3, the rigid disk 4 be arranged on its rotation path contacts with the first side wall, user is by increasing the motive force of upset window 2, support force between window 2 and rigid disk 4 and stiction are increased, therebetween the support force produced and stiction make the two keep relative static, thus it is fixing to realize window 2 position.Time when needed in window 2 overturn cover, by applying downward thrust to lift groove 1, and being greater than the stiction between the first side wall and rigid disk 4, the first side wall being turned round around jointed shaft 3, and then realizes covering of window 2.
Adopt the method that rigid disk 4 is set, effectively can improve the bonding strength that clamping supports, make more stable being supported and fix of window 2.
In a preferred implementation provided by the utility model, hinge hole is adjusted.The first hinge hole on window 2 is elongated hole, or the second hinge hole on the inwall of inspection hole 6 is elongated hole.Can know, by the first hinge hole or the second hinge hole are set to elongated hole, window 2 can rotate relative to main lid 5, simultaneously can also and main lid 5 between produce and relatively slide along elongated hole direction.Lift groove 1 in use, first, is upwards mentioned by the protective cover that the present embodiment provides, and window 2 is rotated around jointed shaft 3; Then, window 2 is lifted, make it higher than former articulated position, then rotate, the first side wall is contacted with rigid disk 4 and stuck.The method expands the rotatable scope of the first side wall, the clamping position of the first side wall and rigid disk 4 is also expanded simultaneously, facilitates the use of operator.
Optionally, above-mentioned first hinge hole and the second hinge hole also can be circular hole.
In a preferred implementation provided by the utility model, window 2 is specifically set to the window 2 that centre is fixedly connected with organic sheet glass, window 2 is the middle forms with through hole, throughhole portions has been bolted polymethyl methacrylate sheet, is realized checking below window 2 by polymethyl methacrylate sheet.
Optionally, it is leg-of-mutton rigid disk 4 that the shape and structure of rigid disk 4 is not limited to cross section, can adjust according to concrete service condition.
Optionally, rigid disk 4 and boss are for being welded to connect, or other have being fixedly connected with of intensity guarantee.
Optionally, be not limited between above-mentioned polymethyl methacrylate sheet and window 2 and be bolted, also can adopt modes such as pasting connection, can adjust as the case may be during use.
Except the protective cover that above-described embodiment provides, the utility model also provides a kind of distribution box comprising protective cover disclosed in above-described embodiment.Above-mentioned protective cover can be used as the top cover of distribution box or the side cover by side-overturning, because distribution box is provided with above-mentioned protective cover, performance easy to use, safe is good, and enhances the useful life of distribution box, the structure of other each several parts of this distribution box please refer to prior art, repeats no more herein.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
Above a kind of distribution box provided by the utility model and protective cover thereof are described in detail.Apply specific case herein to set forth principle of the present utility model and execution mode, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection range of the utility model claim.
