Abstract
The utility model relates to a supporting hollow pipe in a fireproof lock. The supporting hollow pipe in the fireproof lock comprises a body, the body comprises a left pipe body and a right pipe body which are symmetrically arranged, and a vertical plate is connected between the left pipe body and the right pipe body. The supporting hollow pipe in the fireproof lock is simple in structure. Compared with an existing supporting hollow pipe in the fireproof lock, the supporting hollow pipe in the fireproof lock is of an integral structure and formed by plates in a bending mode, and therefore the supporting hollow pipe in the fireproof lock greatly reduces manufacturing cost, just needs one-step installation, saves installing time, promotes installing efficiency, reduces installing cost and has great economic benefit and practicality.
Description
Technical field
The utility model relates to the Fire-proof lock field, relates in particular to the hollow section of Fire-proof lock.
Background technology
Fire-proof lock generally is used for places such as each megastore, supermarket, mansion, the damage of door lock when being used for preventing fire.See accompanying drawing 1 and accompanying drawing 2, existing Fire-proof lock mainly comprises by cover plate 2 and covers the lock body 1 that base plate 3 forms, connection side's dead bolt device 4 and oblique dead bolt device 5 in the lock body 1, base plate 3 is fixedlyed connected hollow section 6 with 2 of cover plates, the effect of hollow section 6 is: the one, play the guider screw effect, be convenient to the tapered end (not shown) is installed on the lock body 1, namely screw passes hollow section 6 tapered end is connected with lock body 1; The 2nd, can prevent that screw from screwing back shroud 2 and base plate 3 past lock body 1 internal strains.Hollow section 6 comprises that two ends have the hollow body of short slot 61, and general mounted in pairs is in lock body 1, and its shortcoming is that the mounted in pairs cost is higher, and installs consuming time morely, causes the cost of production height of Fire-proof lock.
The utility model content
The applicant is at these shortcomings of hollow section in the above-mentioned existing Fire-proof lock, and the support hollow section in a kind of simple in structure, easy for installation, Fire-proof lock that cost is low is provided.
The technical scheme that the utility model adopts is as follows:
Support hollow section in a kind of Fire-proof lock comprises body, and body comprises symmetrically arranged left body and right body, connection board between left body and right body.
Further technical scheme is:
Left side body and right body all have opening;
Opening is towards the plane of symmetry of left body and right body;
The two ends of riser have short slot;
In short slot, the junction of left body and right body and riser all has groove.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, support hollow section in the relatively more existing Fire-proof lock, owing to adopt the one form structure, and by the sheet material bending and molding, greatly reduce manufacturing cost, and only need once mounting, saved the set-up time, improve installation effectiveness, reduced installation cost, had very big economic benefit and practicality.
Description of drawings
Fig. 1 is the structure chart of existing Fire-proof lock.
Fig. 2 is the existing structure chart that supports hollow section.
Fig. 3 is front view of the present utility model.
Fig. 4 is the vertical view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 3, Fig. 4, the utility model comprises body 7, and body 7 comprises symmetrically arranged left body 71 and right body 73,73 connection boards 72 of left body 71 and right body.Left side body 71 and right body 73 all have opening 74, and opening 74 is towards the plane of symmetry of left body 71 with right body 73; The two ends of riser 72 have short slot 75, in short slot 75, left side body 71 and right body 73 all have groove 76 with the junction of riser 72, wherein the setting of short slot 75 can be convenient to left body 71 and right body 73 and be inserted in the aperture on the lock bottom plate, and groove 76 is convenient to the bending and molding of left body 71 and right body 73.
The utility model is by the sheet material bending and molding, and more original hollow section greatly reduces processing cost, and realizes once mounting, has reduced installation cost, has improved installation effectiveness, has very big economic benefit and practicality.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
