Abstract
The utility model provides a novel screw of being applied to under abominable operating mode locking device, mainly by: the connecting piece, constituteed by connecting piece, housing screw, briquetting, connecting screw. With connecting screw fastening by connecting piece and connecting piece, press the briquetting on connecting screw's the end and tighten with the housing screw, utilize the briquetting with by the clearance between the connecting piece, make the briquetting take place elastic deformation, make the briquetting produce the resilience force, utilize this resilience force to play locking effect to the housing screw, make the more reliable connecting screw that compresses tightly of briquetting simultaneously, finally reach and prevent the loose purpose of taking off of connecting screw.
Description
Technical field
This utility model is related to machine-building, specifically a kind of new screw check dress being applied under bad working environments
Put, be particularly well-suited to the locking of under the bad working environments such as shield, smelting, mine screw.
Background technology
Although the locking mode of screw has a many kinds, but is applied to the anti-of screw under the bad working environments such as shield, smelting, mine
Loose measure formula is considerably less, or anti-loosing effect is undesirable or does not allow quick detachable, causes and has a strong impact on to production or construction.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of solid and reliable can be applicable under bad working environments
Screw check device, is reduced or is prevented because of screw is released having a strong impact on of causing, it is ensured that production or the safety constructed and efficiency.
For achieving the above object, this utility model is employed the following technical solutions：A kind of new is applied under bad working environments
Screw check device, mainly by：Connector (1), connected piece (2), housing screw (3), briquetting (4), joint bolt (5) group
Into.The connector (1), connected piece have corresponding screw on (2), and both fit, screw correspondence, by joint bolt (5)
Connect connected piece (2) and connector (1) and fasten, respectively there is a compression spiral shell adjacent joint bolt (5) left and right on connected piece (2)
Oncomelania hole；The briquetting (4) is one piece of steel spring plate, has joint bolt (5) adjacent with two in spring steel plate face apart from phase
The rectangular channel of matching is ensured on briquetting (4) under plane and connected piece (2) with accommodating the overhanging head of screw of joint bolt (5)
Gap is left between plane.On rectangular channel another side, adjacent rectangle groove or so respectively has six square bolt holes and counterbore in one, compresses
Screw (3) screws in corresponding housing screw screw on connected piece (2) by counterbore, interior six square bolts hole.When housing screw (3)
After compressing briquetting (4), due to having gap between briquetting (4) and connected piece (2), make briquetting (4) that elastic deformation to occur, so that
Briquetting (4) produces resilience force, locking effect is played to housing screw (3) using the resilience force, while making briquetting (4) more reliable
Joint bolt (5) is compressed, the purpose for preventing joint bolt (5) from releasing is finally reached.
There is following superiority due to adopting above-mentioned technical proposal, this utility model：This utility model simple structure, reality
With the resilience force produced by elastic deformation after compacted using briquetting (4) produces locking effect to housing screw (3), and effect is more
Plus it is solid and reliable.While preventing joint bolt (5) from releasing, the rectangular channel on pressing plate (4) can be to joint bolt (5) termination shape
Into effective protection, it is to avoid termination is worn or collides with.This utility model range of application is wider, and every screw with plush copper is basic
The device can be adopted.
Description of the drawings
Fig. 1 is this utility model structural representation.
In Fig. 1：Connector -1, connected piece -2, housing screw -3, briquetting -4, joint bolt -5.
Specific embodiment
This utility model is described in further details below in conjunction with the accompanying drawings：
Connected piece 2 and connector 1 are fastened with joint bolt 5, briquetting 4 is pressed onto on the termination of joint bolt 5 and with pressing
Tight screw 3 is tightened, and using the gap between briquetting 4 and connected piece 2, makes briquetting 4 that elastic deformation to occur, and produces back briquetting 4
Elastic force, locking effect is played using the resilience force to housing screw 3, while the more reliable compression joint bolt 5 of briquetting 4 is made, most
The purpose for preventing joint bolt 5 from releasing is reached eventually.
Claims (1)
1. a kind of new screw check device being applied under bad working environments, mainly by：Connector (1), connected piece (2),
