Abstract
The utility model discloses a metal coffin locking device which comprises a baffle (3) clamped on a vertical plate, wherein the baffle (3) is provided with two clamping claws (3-1) which are clamped in an annular limiting groove (4-1) of a locking screw (4) from the front side and the rear side respectively. Axial limiting of the locking screw is achieved through the baffle limiting mode, and the locking device is long in service life.
Description
Technical field
This utility model relates to a kind of locking device, specifically the metal coffin locking device.
Background technology
The patent No. is that 200320120386.7 Chinese utility model discloses a kind of " with the sanitary coffin of locking device ", its locking
Device is provided with annular interstage sleeve, be used to limiting the axial displacement of tie down screw.Between its annular interstage sleeve and tie down screw, by elastic cylindrical pin, link together, because the Quenching Treatment of elastic cylindrical pin is restive, the hardness inequality, when lock body moves to the extreme position of locking or unclamping, the stressed of elastic cylindrical pin is maximum, and at this moment there will be two kinds of situations: the first situation, when the elastic cylindrical pin quenching hardness when excessive (surpass require scope), elastic cylindrical pin can be subject to the effect of shearing force, is easy to elastic cylindrical pin is shredded; The second situation, when elastic cylindrical pin quenching hardness too small (surpassing the scope that requires), elastic cylindrical pin can be subject to the effect of shearing force, and elastic cylindrical pin elasticity is eliminated, and elastic cylindrical pin will come off when backhaul.
The utility model content
Technical problem to be solved in the utility model is, a kind of metal coffin locking device is provided, and by the baffle limiting mode, realizes the axial limiting of tie down screw, and locking device has longer service life.
It is as follows that this utility model solves the problems of the technologies described above the technical scheme that adopts:
The metal coffin locking device, comprise that be used to connecting the guide plate of coffin casing, guide plate comprises flat board and the riser of one each other, and riser is positioned at flat back; On described riser, offer through hole; Also comprise the tie down screw that passes described through hole, on described tie down screw, nut is installed, also comprise the lock body that rear end is connected with described nut, on described lock body, also offer locked groove, also comprise be used to being fixed on the lock on the coffin case lid, it is characterized in that: described tie down screw is with annular spacing groove; Also comprise the baffle plate that is connected on described riser, described baffle plate is with two claws, and described two claws snap in respectively described annular spacing groove from the both sides, front and back.
On described flat board, offer gathering sill, on described lock body, be installed with the rivet that is positioned at described gathering sill.
Good effect of the present utility model is:
During the rotational lock screw rod, due to baffle plate, be inserted in the annular spacing groove of tie down screw, tie down screw can not produce axially-movable, through the threaded engagement of tie down screw and nut, rotates and pulls back lock body, make the locked groove of lock body fasten lock, realized the locking between coffin case lid and coffin casing.This utility model has been realized the axial limiting of tie down screw by the baffle limiting mode, locking device has longer service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.This figure has omitted the front portion of lock body.
Fig. 2 is the structural representation of lock body of the present utility model front portion.This figure is also be used to showing the coffin case lid and being arranged on the lock on case lid.
Fig. 3 is the planform schematic diagram of this utility model tie down screw.
Fig. 4 is the planform schematic diagram of this utility model baffle plate.
The specific embodiment
Below in conjunction with drawings and Examples, further illustrate this utility model.
As shown in Figure 1, 2, this utility model comprises be used to the guide plate 1 that connects the coffin casing, and guide plate 1 comprises flat board and the riser of one each other, and riser is positioned at flat back.On described flat board, offer gathering sill 1-1, on described riser, offer through hole.This utility model also comprises the tie down screw 4 that passes described through hole, and the nut 5 of hex nut form is installed on described tie down screw 4.As Fig. 3, described tie down screw 4 is also with annular spacing groove 4-1.This utility model also comprises the lock body 6 that rear end and described nut 5 weld mutually, on described lock body 6, is installed with the rivet 2 that is positioned at described gathering sill 1-1.On described lock body 6, also offer locked groove 6-1.This utility model also comprises the baffle plate 3 that is connected to as shown in Figure 4 on described riser, and described baffle plate 3 is with two claw 3-1, and described two claw 3-1 snap in respectively described annular spacing groove 4-1 from the both sides, front and back, be used to limiting moving axially of tie down screw 4.This utility model also comprises be used to being fixed on the lock 7 on coffin case lid 8.
Rotational lock screw rod 4, due to baffle plate 3, be inserted in the annular spacing groove 4-1 of tie down screw 4, tie down screw 4 can not produce axially-movable, through tie down screw 4 and the threaded engagement rotation of nut 5, pull forward lock body 6, make the locked groove 6-1 of lock body 6 fasten lock 7, realized the locking between coffin case lid 8 and coffin casing.During reverse rotation tie down screw 4, lock body 6 moves backward, realizes release.When lock body 6 moved forward and backward, rivet 2 slided and realizes steadily guiding in gathering sill 1-1.
Claims (2)
1. the metal coffin locking device, comprise the guide plate (1) be used to connecting the coffin casing, and guide plate (1) comprises flat board and the riser of one each other, and riser is positioned at flat back; On described riser, offer through hole, also comprise the tie down screw (4) that passes described through hole, nut (5) is installed on described tie down screw (4), also comprise the lock body (6) that rear end is connected with described nut (5), on described lock body (6), also offer locked groove (6-1), also comprise that it is characterized in that: described tie down screw (4) is with annular spacing groove (4-1) be used to being fixed on the lock (7) on coffin case lid (8); Also comprise the baffle plate (3) that is connected on described riser, described baffle plate (3) is with two claws (3-1), and described two claws (3-1) snap in respectively described annular spacing groove (4-1) from the both sides, front and back.
2. metal coffin locking device as claimed in claim 1, is characterized in that: on described flat board, offer gathering sill (1-1), on described lock body (6), be installed with the rivet (2) that is positioned at described gathering sill (1-1).
