Abstract
The utility model discloses a pneumatic telescopic supporting rod, relates to mechanical devices special for rescue, emergencies, structural fire protection and the like, and particularly belongs to a telescopic supporting rod applied to supporting of heavy articles. The pneumatic telescopic supporting rod comprises an inner barrel (3), an outer barrel (5) and an end component. The end component is fixedly and respectively connected with the top end of the inner barrel and the bottom end of the outer barrel. The pneumatic telescopic supporting rod is characterized in that threads are arranged on the outer wall of the inner barrel, and are sleeved with a fixing nut (4). The inner barrel is arranged inside the outer barrel, a piston (10) is mounted at the lower end of the inner barrel, and the inner barrel, the piston and the inner wall of the outer barrel form a closed cavity. A pneumatic connector (11) is arranged at the bottom end of the outer barrel. The pneumatic telescopic supporting rod has the advantages of being stable, reliable, flexible and rapid in assembling and adjustment, high in adaptability and high in safety factor.
Description
Technical field
The utility model relates to the special-purpose mechanical device such as a kind of rescue, structural fire protection, particularly belongs to a kind of retractable support lever that weight supports that is applied to.
Background technology
In job sites such as rescue and constructions works, sometimes need to build some interim bracing or strutting arrangements, to construct working space or to implement security protection, for carrying out follow-up work preparatory condition, so there is being applied to the support bar of this object on domestic market, 1), the weight that can bear of support bar is much smaller than the requirement of rescue site but at present product all adopts the fixing means of two bolt-types, and its all load-bearing all focus on two latches, thereby have following defect:; 2), spent time of assembly and disassembly is long, may miss best gold rescue time; 3), support column inner/outer tube guiding clearance is large, easily causes inclination, supports unstablely, and then causes potential safety hazard; 4), bearing height decides by pin-and-hole spacing, cannot accomplish fine setting, causes it when supporting, to be difficult to play substantial effect.
Summary of the invention
The purpose of this utility model is to provide a kind of novel Pneumatic extension support bar, with reach supporting & stablizing firmly, assembling flexible adjustment, object safely and efficiently.
Pneumatic extension support bar provided by the utility model, comprises inner core, urceolus and end member; Described end member respectively with inner core top, urceolus bottom fixed connection, it is characterized in that, on inner tank theca, be provided with screw thread, on it, cover has a hold-down nut; Inner core is placed in urceolus inside, and lower end is provided with piston, forms closed cavity with outer tube inner wall; Urceolus bottom is provided with pneumatic joint.
Pneumatic extension support bar provided by the utility model, in use, after being placed, by pneumatic joint, connect external air source, utilize air pressure by inner core together with hold-down nut jack-up, when it rises to behind target location, hold-down nut is rotated down, make on its lower limb and urceolus along close contact; After use finishes, by pneumatic joint, emit gas, rotate up afterwards hold-down nut, inner core is contracted in urceolus.
Because the utility model is used hold-down nut, fix, the weight of being born by support bar is distributed to the contact surface of whole hold-down nut, has effectively increased its useful load.In addition, can effectively solve the problem of height fine adjusting function in support process, support bar can be locked to height arbitrarily.And supporting and unloading process are simple and convenient, effectively shorten assembling and reinforce the time used.Have reliable and stable, assembling and flexible adjustment rapidly, strong adaptability, good effect that safety factor is high.
Accompanying drawing explanation
Accompanying drawing partly discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model structural representation;
Fig. 2, the utility model cross-sectional view.
The specific embodiment
As shown in Figure 1, Pneumatic extension support bar provided by the utility model, comprises inner core 3, urceolus 5, is provided with screw thread on inner tank theca, and on it, cover has hold-down nut 4.
As shown in Figure 2, inner core lower end is provided with piston 10, and inner core is placed in urceolus inside, and piston and outer tube inner wall form closed cavity.Urceolus bottom is provided with pneumatic joint 11.
In addition, as shown in Figure 2, the overlapping binding site of inner core and urceolus is provided with inner sleeve 9, by screw thread and inner core, connects.The existence of inner sleeve 9 can be filled up the gap between inner core and urceolus, has avoided rocking between inner core and urceolus, and inner core and urceolus are fixed on to same vertical plane, makes it vertically stressed, has avoided run-off the straight.
As shown in Figure 1, for ease of the utility model, coordinate with external bracing thing, inner core top, urceolus bottom respectively with corresponding end member fixed connection.Described end member refers to inner core joint 2, urceolus joint 6, is connected respectively by internal thread with inner core top with urceolus bottom.
As shown in Figure 2, described end member can also comprise supporting platform seat 1, is linked in respectively the outer face of inner core joint 2, urceolus joint 6.The connection of inner core joint and supporting platform seat 1 is achieved in that the stem stem 8 of inner core joint and supporting platform seat is fixing by latch 13, and described latch 13 overcoats have spring 14, and latch one end is inserted in the stem stem of supporting platform seat, and the other end is close to blind nut 12.
Claims (5)
