Abstract
A double-arm lever press-connected glass door of switch cabinet comprises a doorframe, a trim strip, and glass installed between the doorframe and the trim strip, is characterized in that a mounting frame is fixed on the doorframe; a support hole is formed on the mounting frame; and one end of the trim strip penetrates through the support hole and is connected with the mounting frame through a fixing mechanism, and the other end thereof tightly presses on the glass. The utility model has the advantages of compact structure, good appearance, convenient maintenance, low failure rate and long service life conveniently and reliably clamping the glass on the doorframe to avoid fall off, thereby indirectly guaranteeing the safe power supply.
Description
(1), technical field
The utility model relates to the parts on a kind of switch cubicle, the glass door on particularly a kind of switch cubicle.
(2), background technology
Existing switch cubicle glass door has generally comprised doorframe and press strip, and glass is installed between doorframe and the press strip, and press strip one end is supported on the doorframe, the other end and glass crimping, the middle part of press strip is provided with porose, a nut bolt pass this hole and doorframe affixed, as shown in Figure 2.Described press strip is a basic point with the end that directly is connected with doorframe, under the effect of nut, with the glass contact point be that the point of application applies thrust to glass, glass is fixed on the doorframe.Formed by this way glass door, because bolt acts on the press strip to produce the tension arm length to the glass thrust, all the time act on reverse resistance arm length on the press strip less than glass, the pulling force that makes bolt put on press strip puts on the thrust of glass all the time greater than press strip.The pulling force of press strip is too small if bolt puts on, and press strip just can not well attach to glass on the doorframe, and glass easily comes off and is damaged, and makes the electric equipments such as unit switch in the switch cubicle expose out, and electric shock accidents easily meets accident; If it is excessive that bolt puts on the pulling force of press strip, though can attach on the doorframe glass is very reliable, because bolt and nut are stressed bigger, modification usually easily takes place and damage, the failure rate height if select quality bolt and nut preferably for use, then can cause cost higher.
(3), summary of the invention
The purpose of this utility model just provides the switch cubicle double-arm lever compression joint type glass door of a kind of compact conformation, good looking appearance and long service life, and what it can be convenient and reliable is clamped in glass on the doorframe.
The purpose of this utility model is to realize by such technical scheme, it includes doorframe and press strip, glass is installed between doorframe and the press strip, it is characterized in that: be connected with installing rack on the doorframe, installing rack is provided with supported hole, one end of press strip passes supported hole and is connected with installing rack by fixed mechanism, and the other end and glass are pressed against each other.With the supported hole is fulcrum, and to be exactly fixed mechanism apply the power arm of pulling force to press strip to the left part that press strip is positioned at fulcrum, and the right part that press strip is positioned at fulcrum is exactly the resistance arm that press strip produces reverse resistance when clamping glass.The length of power arm and resistance arm arbitrarily is set as required, as, power arm length is set greater than resistance arm length, fixed mechanism just can make things convenient for, reliably with the glass firm grip on doorframe.
Since adopted technique scheme, the advantage that the utlity model has compact conformation, good looking appearance and be convenient to keep in repair, and what it not only can be convenient and reliable is clamped in glass on the doorframe, prevent that glass from coming off, ensured power supply safety indirectly, and failure rate is low, long service life.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of existing switch cubicle glass door;
Among the figure: 1. doorframe; 2. press strip; 3. glass; 4. installing rack; 5. supported hole; 6. bolt; 7. pilot hole; 8. screw; 9. vibration damping Non-slip material.
(5), embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes doorframe 1 and press strip 2, glass 3 is installed between doorframe 1 and the press strip 2, it is characterized in that: be connected with installing rack 4 on the doorframe 1, installing rack 4 is provided with supported hole 5, one end of press strip 2 passes supported hole 5 and is connected with installing rack 4 by fixed mechanism, and the other end and glass 3 are pressed against each other.
Now further specify operation principle of the present utility model in conjunction with Fig. 1: with supported hole 5 is fulcrum, the left part that press strip 2 is positioned at fulcrum is exactly the power arm that 6 pairs of press strips 2 of bolt apply pulling force, when the right part that press strip 2 is positioned at fulcrum is exactly press strip 2 pressed glass 3, the resistance arm of the reverse resistance of generation of 3 pairs of press strips 2 of glass.The length of design motivation arm is equal to or greater than the length of resistance arm, make bolt 6 only need press strip 2 left parts are applied less pulling force, just can make the right part of press strip 2 that glass 3 is applied bigger pressure, with glass 3 tightly attach on the doorframe 1 in, also avoided bolt 6 because of stressed excessive being damaged, or because of selecting for use the higher bolt of quality 6 to increase cost.
The utility model is provided with the installing rack of band supported hole 5 on doorframe, installing rack 5 is packed into behind the press strip 5, makes press strip 5 become two arm levers, as shown in Figure 1.According to actual needs, rationally set two arm of forces length separately and ratio each other, apply less relatively pulling force, just glass 3 can be overlayed reliably on doorframe 1 at 6 pairs of press strips 2 of adjusting bolt.So promptly reach the purpose of pressed glass 3, make bolt 6 bear less relatively stress again.And prior art, as shown in Figure 1, press strip 2 with doorframe 1 contact point be indication, by bolt 62 pairs of glass 3 of press strip are exerted pressure, so that glass 3 is attached on the doorframe 1.It is short with the arm of force of press strip 2 oppositions than glass 3 effects all the time that 6 pairs of press strips 2 of this bolt apply the arm of force of active force.
As shown in Figure 1, described fixed mechanism comprises bolt 6, and installing rack 4 is provided with pilot hole 7, and corresponding pilot hole 7 is provided with screw 8 on the press strip 2, and the screw 8 that bolt 6 one ends pass pilot hole 7 and press strip 2 is threaded.Regulate the pulling force of 6 pairs of press strips 2 of bolt, press strip 2 is overlayed glass 3 on doorframe 1 reliably.In addition, because bolt 8 bottoms are hidden in the installing rack 4, make the utility model good looking appearance.This fixed mechanism also can be rivet or other can with press strip 2 with install 4 and be fixed together each other, and press strip 2 is produced the device of pulling force.
Be provided with vibration damping Non-slip material 9 between glass 3 and doorframe 1 and/or the press strip 2.As shown in Figure 1, between glass 3 and doorframe 1, be provided with vibration damping Non-slip material 9,, simultaneously, prevent to produce slide relative between glass 3 and the doorframe 1 to alleviate or to eliminate the in use suffered impulsive force of glass 3.
