Description

Member fixing assembly of guardrail support frame

Technical Field

The utility model relates to a guardrail support frame, concretely relates to subassembly is fixed to member of guardrail support frame.

Background

Generally, the stair guardrail is easy to age and corrode due to erosion of rain or air after long-term use. In order to improve the safety of the guard rail in use, the guard rail needs to be repaired after being cut after being aged or corroded. Before repairing, in order to prevent the guardrail from toppling over due to external force or aging seriously and generate potential safety hazards, an applicant wants to design a guardrail support frame so as to temporarily reinforce and support the guardrail and prevent accidents. In order to provide enough operating space for the later-stage repair guardrail, the applicant wants to install the guardrail support frame at the side end of stepping on stairs, and the guardrail support frame is fixed at the vertical rod at the side of stepping on one end of the vertical rod and is installed at one side of the vertical rod, and the tail end of the rod can be fixed with a rod. The required rod piece fixing assembly needs to be capable of meeting the fixing positions of guardrail cross rods of various specifications, and meanwhile, the rod piece fixing assembly can be well fixed with the cross rods and is convenient to detach.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide one kind can satisfy the fixed position of various specification guardrail horizontal poles, simultaneously, can also with the better fixed of horizontal pole, and convenient to detach's the fixed subassembly of member of guardrail support frame.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a subassembly is fixed to member of guardrail support frame, its characterized in that, it includes that one can overlap and establish in the pole setting of guardrail support frame to the installation cover that slides and fix a position in pole setting length direction is sheathe in and is installed a locating plate that can the rotation in a circumferential direction, the locating plate is the rectangular plate that the middle part has the spout, is equipped with two one end in the spout of locating plate and runs through the spout, and the other end can with guardrail horizontal pole looks joint or the horizontal pole support piece of centre gripping on the guardrail horizontal pole, horizontal pole support piece can slide along spout length direction to at horizontal pole support piece axial direction back-and-forth movement and location. Thus, the mounting sleeve of the rod piece fixing assembly can slide up and down and be positioned, so that the positioning plate above the rod piece fixing assembly is driven to move up and down along with the mounting sleeve, the mounting height of the positioning plate is adjusted to enable the positioning plate to correspond to the guardrail cross rod, and after the position of the positioning plate is adjusted, the mounting sleeve can be fixed to enable the position of the mounting sleeve to be fixed, and displacement cannot be generated under the influence of gravity and operation; after the positioning plate can rotate in the circumferential direction, the rotating angle of the positioning plate can be adjusted to enable the positioning plate to correspond to the position of the guardrail cross rod to be supported; the cross bar supporting piece can slide in the sliding groove of the positioning plate, and the relative position of the cross bar supporting piece and the cross bar of the guardrail is adjusted, so that the cross bar supporting piece is conveniently clamped on the cross bar from a cutting position or directly clamped on the cross bar of the guardrail from the side end, and the installation is more convenient; and the horizontal pole support piece can be at its self axial direction back-and-forth movement, the interval between adjustable its tip and the guardrail horizontal pole makes it can be well with the clamping of guardrail horizontal pole looks centre gripping or joint. And the mode that adopts joint and centre gripping is fixed with the guardrail horizontal pole, both has better fixed effect, simultaneously, still convenient to detach, and the mode of joint and centre gripping has the controllability, can adapt to the guardrail horizontal pole of different diameters fixedly.

Furthermore, the mounting sleeve is also provided with a positioning bolt of which the tail end penetrates through the outside of the sliding groove, the positioning plate can circumferentially rotate by taking the positioning bolt as a center, a positioning nut in threaded fit with the positioning bolt is arranged on each positioning bolt and on the outer side of the positioning plate, and the positioning plate can be fixed at the side end of the mounting sleeve by rotating the positioning nut. Like this, the positioning bolt that sets up not only can regard as bolt and set nut cooperation fixed positioning plate, can also play the effect of pivot, makes the positioning plate rotate under the support of pivot, realizes the angular adjustment of positioning plate.

Furthermore, the cross rod support piece comprises a support screw rod penetrating through the sliding groove, a cross rod fixing part used for being clamped with the cross rod of the guardrail is installed at the inner end of the support screw rod, and a locking nut used for fixing the screw rod in the sliding groove is sleeved at the outer end of the support screw rod. Like this, the screw rod can slide in spout length direction, simultaneously, can also fix the horizontal pole support piece on the locating plate with lock nut cooperation. And the member bar clamping part can clamp the guardrail cross bar, so that one end of the member bar clamping part is fixed with the cross bar, and the other end of the member bar clamping part is fixed on the positioning plate through the locking nut to form a support for the guardrail cross bar.

Furthermore, the cross rod fixing part comprises an installation part fixedly installed at the inner end of the screw rod, the installation part is vertically arranged, the upper end and the lower end of the installation part are respectively and rotatably provided with an arc-shaped clamping plate, the two arc-shaped clamping plates are oppositely arranged and form a cylinder after being encircled with the installation part; a fixing plate is fixed at the tail end of each arc-shaped clamping plate, and a corresponding through hole is formed in each fixing plate; the two fixing plates are matched and fixed together with the nut after penetrating through the through holes of the two fixing plates through a bolt. Like this, during the use, through pulling the installed part, make the one end of two installed parts open to effectively increase its centre gripping angle, place the guardrail horizontal pole in between the drum that two installed parts formed from the department of opening of two installed parts again, lock two installed parts through bolt and nut cooperation at last. Because can open and shut between the installed part, and then can satisfy the horizontal pole centre gripping demand of different diameters when the centre gripping for the member centre gripping does not have the commonality more.

Furthermore, a rubber pad is arranged on the inner side of each arc-shaped clamping plate, and the outer end surface of each rubber pad is in a sawtooth shape. Therefore, the saw teeth on the rubber pad can increase the friction force between the arc-shaped clamping plate and the guardrail cross rod, so that the clamping is firmer and is not easy to loosen under the influence of external force.

The cross bar fixing part can also adopt the following structure: the cross bar fixing part is a C-shaped clamping plate. Like this, during the use, can directly block C shape block board open-ended one end towards the guardrail on the guardrail horizontal pole, rather than the chucking cooperation.

Furthermore, a flexible anti-skid pad is arranged on the inner side of the C-shaped clamping plate or the sleeve, and a plurality of anti-skid convex points are arranged on the outer end face of the flexible anti-skid pad. Like this, the antiskid bump on the flexible non-slip mat can increase frictional force, prevents to appear becoming flexible under the external force influence.
