Abstract
The utility model discloses a metering observation window, comprising a cabinet door, a metal fixing frame, a metal casting die, a screw, a flat gasket, a spring washer and explosion-proof glass. The metal fixing frame is welded to the cabinet door; the explosion-proof glass is embedded on the metal fixing frame; the metal casting die is pressed on the explosion-proof glass and fixed on the metal fixing frame through the screw, the flat gasket and the spring washer and provides a pressure for the explosion-proof glass by the adjustment of tightness of the screw to fix the explosion-proof glass on the cabinet door. The metering observation window effectively solves the problems that synthetic glass has a poor mechanical property and is fragile; binding bars are inclined to aging and the installation is not convenient. The production efficiency is raised and production costs are reduced.
Description
Technical field
The utility model relates to the electric equipment field, in particular a kind of quantitative observation window of box distribution transformer.
Background technology
Box distribution transformer is with the on-load switch of transformer, high powered part and the complete distribution equipment that protective device, low-voltage distribution equipment, low-temperature measurement system and reactive power compensator are combined; Because of considering reasons such as personal safety, environmental factor; Box distribution transformer must be made enclosed housing hermetically sealed, all insulation; But because of control, measurement, detection etc. need; Must have gained some understanding to the function situation of box distribution transformer, therefore need a quantitative observation window to be installed and observe at low-temperature measurement system place.As shown in Figure 1, existing quantitative observation window employing utilizes polymethyl methacrylate 4 and compresses adhesive tape 3, grooved adhesive tape 2 is inlayed and is fixed on the cabinet door 1.But As time goes on adhesive tape occurs aging easily; The polymethyl methacrylate poor mechanical property, fragility is big, and shock resistance is poor; When receiving for the second time unexpected the strike, polymethyl methacrylate is broken easily, and inconvenience is installed when utilizing adhesive tape to inlay fixedly polymethyl methacrylate; Contraposition is inaccurate need be removed adhesive tape if polymethyl methacrylate is installed; Again inlay fixing, inefficiency, production cost is higher.
Therefore, prior art awaits to improve and development.
The utility model content
The purpose of the utility model is to provide a kind of quantitative observation window, aims to provide a kind of mounting structure of new quantitative observation window, makes the quantitative observation window easy for installation, enhances productivity, and reduces production costs.
The technical scheme of the utility model is following:
A kind of quantitative observation window wherein, comprises cabinet door, metal fixed frame, metal casting die, screw, implosion guard; The metal fixed frame is welded on the cabinet door; Implosion guard is embedded on the metal fixed frame, and the metal casting die is pressed on the implosion guard, and the metal casting die passes through screw on the metal fixed frame.
Described quantitative observation window wherein, also comprises plain cushion, is arranged between screw and the metal casting die.
Described quantitative observation window wherein, also comprises the bullet pad, is arranged between screw and the plain cushion.
Described quantitative observation window, wherein, said screw has 12, is symmetrically distributed.
The beneficial effect of the utility model: the utility model is through providing a kind of new quantitative observation window; Solved the polymethyl methacrylate poor mechanical property, adhesive tape occurs aging easily, and inconvenient problem is installed; Make the quantitative observation window more durable; The contraposition handled easily is installed, is enhanced productivity, reduce production costs.
Description of drawings
Fig. 1 is the mounting structure sketch map of original quantitative observation window.
Fig. 2 is the mounting structure sketch map of the new quantitative observation window that provides of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, clear and definite, below with reference to accompanying drawing to the utility model further explain.
As shown in Figure 2, new quantitative observation window comprises cabinet door 1, metal fixed frame 5, metal casting die 6, screw 7, plain cushion 8, bullet pad 9, implosion guard 10.Metal fixed frame 5 is welded on the cabinet door 1, and implosion guard 10 is embedded on the metal fixed frame 5, and metal casting die 6 is pressed on the implosion guard 10, and metal casting die 6 is fixed on the metal fixed frame 5 through screw 7; In order to realize better transmitting the power effect, between screw 7 and metal casting die 6, plain cushion 8 is set.In order to regulate the compressing degree of 6 pairs of implosion guards 10 of metal casting die, between screw 7 and plain cushion 8, bullet pad 9 is set.Metal casting die 6 provides a pressure for implosion guard 10 through the degree of tightness of adjustment screw 7, and implosion guard 10 is fixed on the cabinet door 1.
During actual installation; The workman only needs to be embedded in implosion guard 10 in the metal fixed frame 5 that is welded on the cabinet door 1; Be pressed in metal casting die 6 on implosion guard 10 and the metal fixed frame 5 again; Be fixed on metal casting die 6 on the metal fixed frame 5 with screw 7, plain cushion 8, bullet pad 9, thereby be fixed on implosion guard 10 on the cabinet door 1.Connect through 8,12 bullet pads 9 of 7,12 plain cushions of 12 screws between metal casting die 6 and the metal fixed frame 5; 12 screws 7 are symmetrically distributed; Stressed even to guarantee implosion guard 10, guarantee that implosion guard 10 has enough pressure fixings on metal fixed frame 5.
Adopt the utility model to solve polymethyl methacrylate poor mechanical property, frangible effectively, adhesive tape easy ageing, the inconvenient problem of installation realize enhancing productivity, and reduce production costs.
Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection range of the utility model accompanying claims.
Claims (4)
1. quantitative observation window; It is characterized in that; Comprise cabinet door, metal fixed frame, metal casting die, screw, implosion guard, the metal fixed frame is welded on the cabinet door, and implosion guard is embedded on the metal fixed frame; The metal casting die is pressed on the implosion guard, and the metal casting die passes through screw on the metal fixed frame.
