Abstract
The invention provides a connecting hook of a support frame telescopic rod. The connecting hook comprises a hook body, a locking piece, a clamping piece and a tension spring, wherein the hook body has a downward long opening; the locking piece is hinged to one side of the hook body, and extends outside upper and lower limiting parts; the upper and lower limiting parts are respectively positioned at the upper and lower ends of the opening; the opening is closed by the lower limiting part; and one end of the clamping piece is hinged to the hook body. The connecting hook of the support frame telescopic rod is simple in structure, can be conveniently buckled or unbuckled with the telescopic rod, is quick in mounting and disassembly, and is conveniently used.
Description
Technical field
The present invention relates to a kind of bracing frame telescoping rod and connect hook, belong to daily living article technical field.
Background technology
Existing bracing frame generally uses steel pipe to build, and uses bolt to connect between each steel pipe, after having constructed, has needed to remove one by one, and again sets up when reusing.Although this design meets the needs of engineering to a certain extent, such mode of building needs time and the manpower of at substantial before and after construction, so just affects programming; And demolishing process is also cumbersome, generally take destructive dismounting, this is all irrational.
Summary of the invention
The invention provides a kind of bracing frame telescoping rod to connect and hook, the above problem can be overcome, for the installation of bracing frame and dismounting bring convenience.
For realizing the above, technical scheme provided by the invention is as follows: described connection hook comprises hook body, locking piece, holding part and extension spring, hook body and there is microscler and downward opening, locking piece is articulated in the side that hooks body and on extending, lower limit portion, on, lower limit portion lays respectively at upper end and the lower end of opening, lower limit portion closing openings, one end of holding part is articulated in hook body, the edge that locking piece is adjacent with holding part is provided with first engaging tooth, the edge that holding part is adjacent with locking piece is provided with two the second engaging tooths, resistance surface is provided with between two second engaging tooths, first engaging tooth from during wherein one second dynamic another second engaging tooth of engaging tooth transfer and resistance surface conflict, one end of described extension spring is connected to the eccentric position of locking piece, and the other end is connected to the middle part of holding part, hook on body and arrange locking piece, locking piece extends upper and lower limiting section, lower limit portion closes the opening hooking body, is locked in by telescoping rod and hooks in body, prevents hooking body and departs from telescoping rod, by arranging holding part and arranging mutually engageable second engaging tooth and the first engaging tooth at the edge of holding part and locking piece, utilize extension spring that the second engaging tooth is engaged with the first engaging tooth, make locking piece turn to multiple position by driver card gripping member, realize utilizing lower limit portion opening or closing opening.
This bracing frame telescoping rod connection that the present invention relates to hooks, and structure is simple, and connection can be made to hook can be fastened with telescoping rod easily or trip, and installs and dismantles fast, use very convenient.One end of holding part has driver card gripping member around itself and the operating grip of pivot joint center rotating hooking body.Operating grip can conveniently operate holding part, opens or closes opening to make locking piece.
Accompanying drawing explanation
Fig. 1 is that bracing frame telescoping rod of the present invention connects the structure chart hooked.
