Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of foot stool, especially a supporting foot stool. BACKGROUND

[0002] The supporting foot stool is a general component for providing stable support for various devices, and the core role is to ensure that the device avoids shaking and tilting in use, and guarantees the working effect and safety. For example, the stage sound placing rack disclosed in CN222356498U is composed of a supporting base rod, a supporting foot assembly and an assembly assembly. A guide sliding groove is formed through the supporting base rod. The bottom end of the supporting base rod is connected with a bolt. The inside of the supporting base rod is slidably sleeved with a movable sliding table. The movable sliding table is formed with a connecting block matched with the guide sliding groove. The supporting foot assembly includes a movable sleeve, a supporting leg, a foot pad, a traction rod and a positioning bolt. The inside of the movable sleeve is formed with a butt joint sliding block. The movable sleeve is connected with the guide sliding groove through the butt joint sliding block.

[0003] This structure has two core defects: 1. The length of the supporting leg is fixed, and the complete folding and unfolding depends on the long stroke sliding of the movable sleeve on the supporting base rod, which requires a redundant height of the supporting base rod, and the operation of the upper sliding folding is not convenient; 2. The supporting base rod is hollow and has a long guide sliding groove, and the overall rigidity of the rod body is insufficient, which is easy to bend and deform when bearing heavy equipment. UTILITY MODEL CONTENTS

[0005] The utility model discloses a supporting foot stool, which is convenient to unfold and fold, and can be applied to the stable support requirement of the rod piece.

[0006] The plurality of supporting rods are distributed along the circumference of the center rod, each supporting rod is composed of a plurality of rod columns which are connected in sequence to form a sliding telescopic structure, and the adjacent two rod columns are locked by at least one first locking member. The upper end of the uppermost rod column in each supporting rod is hingedly connected with the connecting seat, and the bottom seat and the lowermost rod column of each supporting rod can jointly form a ground support structure of the supporting foot stool.

[0007] Each supporting rod is connected with the bottom seat through a corresponding connecting rod. The lower end of each connecting rod is hingedly connected with the bottom seat, and the upper end is slidably connected with the corresponding supporting rod through a sliding sleeve. The connecting rod and the sliding sleeve are hingedly connected. The sliding sleeve and the supporting rod are locked by at least one second locking member.

[0008] The clamping seat is provided with a plurality of elastic clamps corresponding to the supporting rods. The supporting rods can be clamped in the corresponding elastic clamps after being folded.

[0009] With the technical scheme, the support rod adopts "multi-section rod column sequentially sleeved + first locking member", which realizes length scalable adaptation to different support height requirements, fixes the length after expansion through the locking member, avoids self-sliding during use, and guarantees the stability of the structure after expansion. The multi-section rod column sleeving structure is designed in a segmented expansion manner, which disperses the expansion stroke of a single support rod to each section rod column while guaranteeing the support strength, greatly reduces the problem of the need to reserve redundant height for the center rod height, and makes the support height adjustment more accurate and flexible.

[0010] The connecting rod is adjusted in expansion angle by moving with the sliding sleeve through "sliding sleeve and support rod sliding cooperation + second locking member", and the expansion angle of the connecting rod is fixed by the second locking member, so that the support foot support is switched flexibly from "folding" to "expansion", and the support stability is further enhanced.

[0011] The elastic clamping of the clamping seat can realize quick clamping after the support rod is folded, avoids random shaking of the support rod in the folded state, and improves the portability and regularity after folding.

[0014] With the further settings, the "support cantilever" on the connecting seat provides the uppermost section rod column of the support rod with a hinged support point extending outward, avoids the problem of "limited expansion angle" when the support rod is directly hinged to the outer periphery of the center rod, expands the expansion span of the support foot support, and improves the support stability; the "empty area" formed between the folded support rod and the center rod provides a dedicated accommodation space for the folded connecting rod, avoids mutual interference between the connecting rod, the support rod and the center rod during folding, and realizes compact folding of the "support rod-connecting rod-center rod".

[0015] The further setting of the utility model discloses: the multi-section rod column in each support rod is sequentially sleeved upwards and downwards, the next section rod column is all slidably arranged in the last section rod column to form sleeved cooperation, the sliding sleeve is slidably arranged outside the uppermost section rod column in the support rod, and a limiting boss is arranged on the outer peripheral wall of the uppermost section rod column.

[0016] The further setting is adopted, the nested structure of "the lower section of the multi-section rod column is inserted into the upper section" is clear, the telescopic direction and assembly logic of the support rod are clearer, the sliding sleeve is limited to "sliding outside the uppermost section rod column", the stress support point of the connecting rod can be accurately controlled to concentrate on the upper part of the support rod, and the unstable expansion angle of the support foot frame caused by the too low driving point of the connecting rod is avoided, the "limiting boss" on the uppermost section rod column is below the sliding sleeve, and the sliding sleeve is abutted during expansion, so that the downward limit of the sliding sleeve can be accurately limited, and the problems of "too large expansion angle and unstable support structure" caused by the excessive downward movement of the connecting rod are avoided, and mechanical limiting protection is provided for the expansion angle of the connecting rod.

[0017] The further setting of the utility model discloses: the first locking part and the second locking part are all screw rod structures with handles, the first locking part is in threaded cooperation with the lower part of the last section rod column, and the end portion is abutted to the outer wall of the adjacent next section rod column to realize locking, and the second locking part is in threaded cooperation with the sliding sleeve, and the end portion is abutted to the outer wall of the uppermost section rod column to realize locking.

[0018] The further setting is adopted, the first locking part and the second locking part are all "screw rod structures with handles", manual screwing operation is not needed, "quick locking / unlocking" is realized, and the use convenience of the support foot frame is improved, the first locking part is in threaded cooperation with the upper section rod column, the end portion is abutted to the outer wall of the lower section rod column, through the double actions of "threaded pre-tightening + end face abutment", the relative positions of the adjacent rod columns can be effectively fixed, and loosening after telescoping is avoided, the second locking part is in threaded cooperation with the sliding sleeve, and the end portion is abutted to the outer wall of the uppermost section rod column, so that the position of the sliding sleeve can be stably fixed, the angle of the connecting rod is not deviated, and the overall support reliability is improved.

[0019] The further setting of the utility model discloses: the elastic clamp includes a clamping hole formed by oppositely arranged first and second clamping pieces, one end of the two clamping pieces is connected with the clamp seat, the other end is away from each other and forms a "V"-shaped opening.

[0020] With the further setting, the elastic clamp is composed of a first clamping piece and a second clamping piece, and a clamping force is generated through elastic deformation of the clamping pieces to tightly clamp the support rod after folding, thereby avoiding falling off during storage; a V-shaped opening is formed at the end of the two clamping pieces, and the V-shaped opening plays a guiding role when the support rod is clamped, so that the support rod can be slid along the V-shaped slope without precise alignment with the clamping hole, thereby improving the convenience of clamping during folding and enhancing the adaptability of the clamp.

[0021] With the further setting, the connecting seat and the clamp seat are both provided with two half-rings that are symmetrically arranged and are locked by fastening bolts after being closed, and the half-rings are arranged on the outer periphery of the center rod.
