The earth brake comprises the following components: a bracket part which isprovided with a plate-shaped support part at the upper end and is offset upwards and is elastic; the fixing pedal rod which has an approximate V-shape and is articulated on the bracket part by a first pin and simultaneously gets across the bracket part extending frontwards and backwards; a fixing releasing pedal rod which is parallely installed at the outside of fixing pedal rod and has a back side that is articulated inside the supporting part through a second pin; and a connecting sheet which is positioned between the second pin and the fixing pin. The back side of fixing pedal rod is installed with a fixing pin which can engage with the bracket part, and the front side is installed with a pedal part.

The unit of low-volatile distribution cabinet includes left and right side plates with double-folded edge, fixed plate, removable back plate, and installation beams being connected. Advantages are: under precondition of not changing original outline structure of unit in draw-out type to reach purpose of operation without opening door. In procedure of operation, function for displaying position requested by national standard is satisfied. Technique of double-folded edge enhances intensity. Thus, thickness of plate is changed to 1.0-1.5mm, and more than 1 / 4 cold steel plate is saved. Electricalconnector pieces on moved plate are still aligned to vertical bus precisely. Both way connector (BC) is in module form. Being connected to BC, the conducting strip is changed to forficiform structurefrom thermal fin type. Thickness of copper plate changes to 2.0mm so as to save material, but still meet requirement of contact insertion and withdraw force, and standard value of temperature rise.

The invention relates to a deep groove ball bearing retainer dismantling method. A retainer of a deep groove ball bearing is positioned and supported by means of an auxiliary bearing dismantling tool so as to be prevented from rotating and then is placed on a working table of a drilling machine, drilling cuttings on the heads of all rivets of the retainer of the deep groove ball bearing are removed by means of a drill bit of the drilling machine, and thus two retainer bodies of the retainer of the deep groove ball bearing are separated to complete dismantling. The deep groove ball bearing retainer dismantling method has the advantages that dismantling operation is easy and convenient, all components of the bearing are prevented from being damaged, accurate bearing disassembly analysis is achieved, and reutilization of qualified components of the bearing is achieved.

The invention discloses a special die for manufacturing a grinding wheel. The special die for manufacturing the grinding wheel comprises a bottom die, an outer upper die, an inner upper die, an inner middle die, a core die and an elastic connecting piece, the core die is sleeved in the core hole in the top of the inner upper die, the inner upper die, inner middle die and bottom die are coaxially arranged in sequence from the top to bottom and sleeved in the outer upper die, and the outer upper die is connected with the bottom die through the elastic connecting piece; the inner middle die is firmly connected with a bottom die support barrel, and the outer diameter of the inner middle die is larger than that of the support barrel; the outer upper die is sleeved with the bottom die through an annular clamp at the bottom, and the outer upper die is in limit connection with the inner middle die; a cavity for forming the grinding wheel is arranged among the inner wall of the outer upper die higher than the top surface of the inner upper die, the outer wall of the core die higher than the top surface of the inner upper die and the top surface of the inner upper die. The special die for manufacturing the grinding wheel is capable of reducing the friction consumption of the die, guaranteeing the grinding wheel production quality and prolonging the service life of the die.

The invention discloses a laver breeding device, which is characterized in that floating ball carriers are formed by fixing floating balls and cross rods, a plurality of floating ball carriers are transversely arranged along the length direction of the breeding net, the floating ball carriers at the front end and the rear end of the breeding net are respectively a front floating ball carrier and arear floating ball carrier, the left side and the right side of the front floating ball carrier and the rear floating ball carrier are respectively tied with a pair of cables, two pairs of the cablesboth comprise first cables and second cables, the free ends of the first cable and the second cable in each pair of cables are tied together and are respectively connected with two third cables, andthe free ends of the two third cables can be respectively fixed with two column piles, so that people can hook the distal end of the cross rods of the front floating ball carrier or the rear floatingball carrier through a pull rod to lift the cross rods, and the whole breeding net can be turned over by taking the two third cables as rotary central shafts of the device, so that laver seedlings canbe soaked and solarized.

The invention discloses a manual and automatic button for a water discharge valve. The manual and automatic button comprises a pressing cylinder, a button shell, a button, an electronic button, a pushing rod, a pushing rod locking block, a locking nut, a wired hose and a steel wire. The button shell is fixedly sleeved into the pressing cylinder and in bolt joint with the locking nut on the outer wall of the pressing cylinder for locking. The button, the electronic button and the pushing rod sequentially and movably sleeved into the button shell. The button is disposed at the end opening of the button shell. The pushing rod penetrates through the button shell. One end of the steel wire is fixedly connected to one end of the button shell. The pushing rod locking block is in fixed sleeve joint with one end of the wired hose and abuts against one end, away from the button, of the pushing rod. The wired hose is movable sleeve joint with the steel wire. By adoption of cooperation among the button, the pushing rod, the pushing rod locking block, the wired hose, the steel wire and the like, the function of opening the water discharge valve can be triggered off during power out in order to ensure that the function of the water discharge valve does not fail during power cut. The manual and automatic button for the water discharge valve is advantaged by being good in operation hand feeling, small in operation force, short in operation stroke and sensitive in triggering.

The invention discloses a valve element and a water way control valve. The valve element comprises a valve shell, a control rod, a water pressure control piece, a water way control sealing piece and a capillary hole forming element. The water pressure control piece forms a water pressure cavity with a first opening and a second opening. An auxiliary water outlet and a main water outlet are formed in the side face of the valve shell, wherein one end is a water inlet end. The water pressure control piece and the water way control sealing piece are arranged in the valve shell in a sleeved mode. The water way control sealing piece is provided with a deforming part which is directly or indirectly matched with the main water outlet of the valve shell in a sealing mode. The capillary hole forming element is arranged on the water way control sealing piece in a sleeved mode, and a capillary hole for being communicated with the water pressure cavity and the water inlet end of the valve shell is formed. The first opening of the water pressure cavity is communicated with the auxiliary water outlet of the valve shell. The control rod is movably arranged the water pressure control piece in a sleeved mode and is provided with a sealing part. The first opening is opened or sealed by the fact that the sealing part moves in the axial direction along with the control rod. The water way control valve comprises a valve body and the valve element. The water way control valve has the advantages that operation force is small, and operation stroke is short.
