Abstract
The utility model discloses an ejector rod, which is designed to solve the problem of insufficient stability of connection of an existing ejector rod with a girder. The ejector rod comprises a support, an ejector rod core, an ejector rod jacket, a limiting steel rib, a lead screw, a positioning pin, a lock and a locking plate. The lower end of the ejector rod core is sleeved in the support, the ejector rod jacket is sleeved outside the upper end of the ejector rod core, the lead screw is arranged inside the ejector rod jacket, the lock is connected to the upper end of the lead screw and can be connected into the locking plate in a clamped manner, and the locking plate is connected with a supported object. A lock hole inside the locking plate is 8-shaped, the lock is trapezoidal with a narrow upper portion and a wide lower portion, and a connecting portion is disposed at the lower edge of the lock and connected with the lead screw. The lead screw adjusts the height of the ejector rod so as to adjust the height of an integral house. The locking plate and the lock adopt novel structures so that the locking plate can be clamped with the lock hole more closely and stably.
Description
Technical field
The utility model relates to a kind of push rod, relates in particular to a kind of height-adjustable push rod.
Background technology
Flourish along with builing industry, the design of structure material and manufacturing have received increasingly extensive concern.It is well-known that construction formwork supports the importance of push rod, can regulate fast flexibly, firm push rod is one of important link of template braced structures.
Yet the design of modern house is more and more personalized, and the identical age of house moulding is gone for ever.The construction in personalized house is day by day increased the requirement of push rod, and it is not enough that soundness is only arranged, and also needs to regulate easily the height of push rod, to reach the difference that adapts to the building construction height and the requirement of horizontality.For the push rod of regular length, solution to this problem is that the different a series of products of production length satisfy the needs in market.But the product of seriation still has concrete dimensions, can't satisfy the customer requirement that varies easily.
Disclosing of a telescopic push rod product arranged now, but on the structure incomplete place is arranged also, make the house of building with this push rod also exist deficiency aspect practicality and the safety.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of more firm push rod that is connected with girder.
For achieving the above object, the utility model is realized by following measure: push rod comprises bearing, push rod core, push rod overcoat, spacing reinforcing bar, screw mandrel, tapered end and the locking plate that connects successively at least; Described push rod core lower end fixed cover is located in the described bearing, the outside, described push rod core upper end is arranged with described push rod overcoat, be provided with described screw mandrel in the described push rod overcoat, described screw mandrel lower end connects described spacing reinforcing bar, described spacing reinforcing bar is positioned at described push rod overcoat and both are fixedly connected with spacer pin, and described screw mandrel is applied mechanically bolt outward with described push rod and is connected, and described screw mandrel upper end connects described tapered end, described tapered end can be connected in the described locking plate, and described locking plate is connected in and supports on the objective body.
Particularly, the lockhole in the described locking plate is 8 shapes, and described 8 shape lockholes are relative tiltedly goes up and tiltedly following two edges are linearly.
Particularly, it is up-narrow and down-wide trapezoidal that described tapered end is, and the lower limb of described tapered end is provided with connecting portion, and described connecting portion connects described screw mandrel, and the length of described connecting portion is greater than the thickness of described locking plate.
The utility model push rod includes screw mandrel, regulates the height of push rod by the effect of screw thread, and then can regulate the height of whole braced structures, satisfies the needs of different buildings room height.The utility model locking plate has adopted the straightsided shape lockhole, makes that structure is more reasonable and practical between locking plate and the lockhole.The utility model tapered end has adopted trapezoidal head design, makes tapered end insert lockhole very easily.
