According to the locking fixture for casting the medium sand box, the size of the locking area formed by the U-shaped locking ring and the locking piece is adjusted through the bolt, and a sealing requirement of the sand box is met; and at the same time, parts are connected together after the locking fixture is unlocked and can be prevented from being lost, the operation is convenient, and the working efficiency is improved accordingly.
Description
Technical field
the utility model relates to a kind of locking fixture, is specifically related to a kind of for casting the locking fixture of cheek.
Background technology
in casting process, to in sandbox, fill after sand, then mould assembling, general is all to adopt the keyway being arranged in casing and case lid to coordinate, add a plurality of connectors that are arranged on casing and case lid outside and realize the closure of sandbox, although can meet the closed requirement of sandbox, but outside a plurality of connectors, substantially be all the mode of with bolts and snap close, obviously, the closed efficiency of sandbox is low, simultaneously in unloading process, bolt connection piece need to be disassembled, and then releasing snap close, cause the parts after dismounting more, easily there is Loss, make troubles to workman's operation.
Summary of the invention
technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of improved for casting the locking fixture of cheek.
for solving above technical problem, the utility model is taked following technical scheme:
a kind of for casting the locking fixture of cheek, sandbox comprises upper box and lower box, locking fixture is for locking upper box is relative with lower box, the both sides of upper box and lower box are equipped with hanger, locking fixture comprises the U-shape lock ring that can be set on upper box or lower box hanger, can come and go mobile lock piece along two vertical edges of U-shape lock ring, be arranged on the contiguous block of U-shape lock ring open end, and match with contiguous block, bolt through contiguous block, the locking region that wherein U-shape lock ring and lock piece form, the hanger of upper box and lower box is all in locking region, the bolt head of bolt can be conflicted on lock piece, and bolt can regulate the size in locking region.
according to concrete an enforcement and preferred aspect of the present utility model, the middle part of contiguous block is provided with connecting hole, and bolt is threaded mutually with connecting hole.Simple and convenient.
according to another concrete enforcement and preferred aspect of the present utility model, the middle part of contiguous block is provided with connecting hole, and the internal diameter of this connecting hole is greater than the external diameter of bolt head, and is fixed with nut in the side that bolt pierces into connecting hole, and bolt is threaded mutually with nut.Practical.
in addition, in above-mentioned specific implementation process, on lock piece, there are two lockholes that run through self, two vertical portions of U-shape lock ring are corresponding to two lockholes, and lockhole internal diameter is greater than the external diameter of U-shape lock ring vertical portion, on the bolt cap of bolt, be also fixed with adjustment means simultaneously through the connecting portion in hole.Be convenient to the locking of bolt.
due to the enforcement of above technical scheme, the utility model compared with prior art tool has the following advantages:
the locking area size that the utility model regulates lock piece and U-shape lock ring to form by bolt, meets the sealing requirement of sandbox, and after locking fixture release, parts still link together, and prevent the loss of parts, easy to operate, thereby increase work efficiency simultaneously.
Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail.
fig. 1 is according to the structural representation of the utility model locking fixture;
wherein: 1, U-shape lock ring; 2, lock piece; 20, lockhole; 3, contiguous block; 30, connecting hole; 4, bolt; 40, bolt head; 41, bolt cap; 5, nut; 6, connecting portion; 60, hole; .
The specific embodiment
as shown in Figure 1, the present embodiment for casting the locking fixture of cheek, this sandbox comprises upper box and lower box, locking fixture is for locking upper box is relative with lower box, the both sides of upper box and lower box are equipped with hanger, locking fixture comprises the U-shape lock ring 1 that can be set on upper box or lower box hanger, can come and go mobile lock piece 2 along 1 two vertical edges of U-shape lock ring, be arranged on the contiguous block 3 of U-shape lock ring 1 open end, and match with contiguous block 3, bolt 4 through contiguous block 3, the locking region that wherein U-shape lock ring 1 and lock piece 2 form, the hanger of upper box and lower box is all in locking region, the bolt head 40 of bolt 4 can be conflicted on lock piece 2, and bolt 4 can regulate the size in locking region, when bolt 4 clockwise (tightening) regulates, lock piece 2 is progressively mobile to the bottom (arch section) of U-shape lock ring, region is locked in dwindling gradually, when bolt 4 counterclockwise (dismounting) regulates, lock piece 2 is progressively mobile to the top (opening portion) of U-shape lock ring, expansion locking region gradually.
on above-mentioned lock piece 2, have two lockholes 20 that run through self, two vertical portions of U-shape lock ring 1 are corresponding to two lockholes 20, and lockhole 20 internal diameters are greater than the external diameter of U-shape lock ring 1 vertical portion.The various ways that is connected with of bolt 4 and contiguous block 3, for example: the middle part of contiguous block 3 is provided with connecting hole 30, bolt 4 is threaded mutually with connecting hole 30; The middle part of contiguous block 3 is provided with connecting hole 30, and the internal diameter of this connecting hole 30 is greater than the external diameter of bolt head 40, and is fixed with nut 5 in the side that bolt 4 pierces into connecting hole 30, bolt 4 is threaded mutually with nut 5, in this example, adopt the latter, its practicality is stronger, uses more convenient.
in addition, in this example, the quick adjustment for the ease of adjustment means to bolt, on the bolt cap 41 of bolt 4, be fixed with connecting portion 6, this connecting portion 6 is provided with the hole 60 that adjustment means is passed, and what make bolt 4 tightens or dismantle very convenient and quick, and operating efficiency is higher.
