Description
Technical field
The utility model relates to various apparatus protective cover plate fixing devices, is specially a kind of mechanical protection fastening device easy to disassemble of new structure.
Background technique
The mode of traditional apparatus protective cover plate fastening has: directly with the bolt rotation, in the position that will protect, the dismounting of this kind fixation method bothers with the protective cover plate fastening, and workload is big, and these holes generally are used for aspects such as air-out, maintenance, observation and processes; Another kind of means of fixation is for after buckling cover plate, link up with on the hook on one side, another side is dead with Elastic Steel device fixing button, though this kind method is convenient, is subjected to the Elastic Steel elastic limit, sealability is not fine, especially at the abominable especially operating conditions of vibration, cover plate is easy to come off, and in the space narrow and small occasion, locking and dismounting need certain space, and certain narrow limitation is arranged.
Summary of the invention
The utility model exist in order to solve existing apparatus protective equipment and to adopt above-mentioned dual mode dismounting complicated, waste time and energy, have certain circumscribed problem, a kind of mechanical protection fastening device easy to disassemble is provided.
The utility model is to adopt following technological scheme to realize: mechanical protection fastening device easy to disassemble, comprise and the close-fitting cover plate of apparatus support, innovative point of the present utility model be cover plate one end have with the apparatus support on the corresponding slot of screwhole position, the other end have with the apparatus support on the corresponding rectangular opening in unthreaded hole position, rectangular opening both sides and be positioned at upper and lower and be respectively equipped with check plate; Also comprise holding down bolt that cooperatively interacts with slot, screw and the adjustable bolt that matches with rectangular opening, unthreaded hole, the bolt head of described adjustable bolt is a flat spiral shell head, is set with on the screw rod and the inboard spring that fixes of apparatus support.The quantity of described slot, rectangular opening, big I are determined according to actual needs.
Adopt structural design of the present utility model, apparatus support and cover plate one end are by screw, slot and holding down bolt locking, the other end is by unthreaded hole, rectangular opening and adjustable bolt, spring locking, simple in structure, easy installation and removal, time saving and energy saving, do not need a lot of spaces, be applicable to any occasion, and sealing structure is good, has certain popularization value.

Embodiment
Mechanical protection fastening device easy to disassemble, as shown in Figure 1, 2, 3, comprise and apparatus support 1 close-fitting cover plate 2, cover plate 2 one ends have with apparatus support 1 on the corresponding slot 4 in screw 3 positions, slot quantity is one, the other end have with apparatus support 1 on the corresponding rectangular opening 6 in unthreaded hole 5 positions, rectangular opening quantity is two, rectangular opening 6 both sides and be positioned at upper and lower and be respectively equipped with check plate 7, the upper and lower sides check plate forms locking groove; Also comprise holding down bolt 8 that cooperatively interacts with slot 4, screw 3 and the adjustable bolt 9 that matches with rectangular opening 6, unthreaded hole 5, as shown in Figure 4, the bolt head of described adjustable bolt 9 is a flat spiral shell head, has through hole 14 on the bolt head, is set with on the screw rod and the apparatus support 1 inboard spring 10 that fixes.
For further optimization structure of the present utility model, the supporting nut 11 that is provided with on the screw rod of adjustable bolt 9, spring 10 upper ends and nut 11 clampings, the inboard clamping of lower end and apparatus support, the screw rod end also is provided with pin-and-hole 12 and pin 13, and further nut is lived in stop.
As shown in Figure 1, 2, be fixed with stiffening plate 15, can play reinforcement effect along slot 4 borders.
As shown in Figure 5, on the surface of contact of cover plate 2 and apparatus support 1 sealing rubber strip 16 is set.
During concrete enforcement, fit on holding down bolt in the screw of apparatus support, and will leave appropriate gap between bolt head and the base surface is so that the screw rod position that allows the slot of cover plate respective end insert holding down bolt; The adjustable bolt of in the unthreaded hole of the apparatus support the other end, packing into, and on its screw rod shock mount, use nut screwing clamping then, pin is inserted in the corresponding pin-and-hole, nut is lived in stop; After assembling above-mentioned parts, cover plate is buckled in support respective aperture position, at first the slot of one end is inserted the screw rod position of holding down bolt, then the rectangular opening of its other end is passed the flat spiral shell head of adjustable bolt, the screwed in place bolt utilizes through hole and instrument on the flat spiral shell head that adjustable bolt is pulled out, and revolves then to turn 90 degrees, and flat spiral shell head is just tightly fixed in the locking groove of check plate formation on the cover board, reach the effect of indentation sealing;
When cover plate need be dismantled, at first by the through hole on the flat spiral shell head and instrument with the adjustable bolt pull-up, revolve and turn 90 degrees, the holding down bolt with the cover plate the other end unclamps then, can pull down cover plate, and motor internal is safeguarded.
