Problems solved by technology

At present, many projects require drilling holes to install suspenders (screws) for indoor ceiling operations such as ceilings, bridge frames, and lamps. When drilling holes, two people are required to operate. One of them is a ladder, and the other is an escalator. The construction is inconvenient for the person who works with the ladder. , low efficiency, and potential safety hazards

Embodiment 1

[0034] A novel perforated frame support jacking structure, comprising a support base and a support rod 11 inserted on the support base, the support base includes a base plate 101 and an outer casing 102 vertically arranged on the base plate; the support rod Inserted in the outer casing along the axial direction of the outer casing, the inner bottom of the outer casing is provided with a hydraulic oil chamber 104 for lifting the support rod, and the outer casing is also provided with a hydraulic cylinder 105 communicating with the hydraulic oil chamber. The cylinder is inserted with a piston rod 106 that can press the oil in the hydraulic cylinder into the hydraulic oil cavity for lifting the support rod. Linear bearings 109 are fixed at the upper ends of the lumens of the inner sleeve and the outer sleeve.

[0035] The support base also includes an inner sleeve 103 that is inserted in the outer sleeve along the axial direction of the outer sleeve and can slide up and down alon...

Embodiment 2

[0039] The difference from the above embodiments is that the base plate is provided with a stud tube 112 with external threads, and the inner wall of the lower end of the outer sleeve is provided with internal threads that are screwed and adapted to the stud tube, and the wall of the stud tube is A through hole for connecting the hydraulic oil chamber and the hydraulic cylinder is opened on the top.

Embodiment 3

[0041]The difference from the above-mentioned embodiment is that the lower part of the inner wall of the outer sleeve is recessed outward to form a limit step 113, and the outer wall of the inner sleeve is convexly formed below the limit step and is used to limit the inner sleeve up and down with the limit step. The stop step 114 of the sliding travel range. The inner wall of the outer casing and the outer wall of the inner casing are respectively provided with adapted guide ribs (115) and guide grooves along the axial direction of the outer casing. Therefore, it is used to prevent the inner sleeve from rotating circumferentially in the outer sleeve, and to ensure that the handle does not drive the inner sleeve when the support rod is rotated to prevent the positioning transverse groove from being covered by the outer sleeve. At the same time, it can also play a guiding role, making the entire structure Movement is more stable.

Abstract

The invention relates to the field of architectural decoration, in particular to a novel punching rack supporting and jacking structure, which comprises a supporting base and a supporting rod inserted into the supporting base, wherein the supporting base comprises a base plate and an outer sleeve vertically arranged on the base plate, and the supporting rod is inserted into the outer sleeve along the axial direction of the outer sleeve; a hydraulic oil cavity for jacking the supporting rod is arranged at the bottom of the inside of the outer sleeve, and the outer sleeve is also provided with a hydraulic cavity communicated with the hydraulic oil cavity; a piston rod which is used for pressing oil in the hydraulic cylinder into the hydraulic oil cavity to jack the supporting rod is inserted into the hydraulic cylinder. The supporting rod can be lifted up along a through groove through a handle so as to jack a hole puncher at the top of the supporting rod, and the piston rod is stepped to be pressed down so as to press the hydraulic oil in the piston rod into the hydraulic oil cavity so as to jack the supporting rod; the operation is diverse and convenient, the supporting rod rises stably, and the punching is safer.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a novel punching frame supporting jacking structure. Background technique [0002] The structural layer or decoration house on the upper part of the existing indoor space is mostly equipped with a ceiling (suspended ceiling) to cover the structural layer of the roof to meet the requirements of indoor use. At present, many projects require drilling holes to install suspenders (screws) for indoor ceiling operations such as ceilings, bridge frames, and lamps. When drilling holes, two people are required to operate. One of them is a ladder, and the other is an escalator. The construction is inconvenient for the person who works with the ladder. , the efficiency is low, and there are potential safety hazards in construction. In order to solve this problem, the simple punching frame with the Chinese patent No. 201120157482.3 adopts a bracket with a supporting wooden square ...
