Abstract
The invention relates to a damping type insertion rod castor device. The damping type insertion rod castor device comprises an insertion rod castor (10) and a damping device (11). The damping type insertion rod castor device is characterized in that the insertion rod castor (10) comprises a wheel (1), a support (2), an insertion rod (3) and a snap spring (4); the damping device (11) comprises an insertion tube (5), a U-shaped support (6), a compression spring (7) and a fixing pin (8). According to the damping type insertion rod castor device, the U-shaped damping device is additionally installed on the basis of the original insertion rod castor; when the castor runs, generated bounces are buffered and damped through the U-shaped damping device, so that swing or collision is reduced when a carrier moves, and the damping type insertion rod castor device is more stable and safer. The damping type insertion rod castor device is suitable for installation and use of small castors with wheel diameters smaller than 100 mm and carriers with loads smaller than 75 kilometers.
Description
Technical field
The present invention relates to a kind of inserted link caster device, especially relate to a kind of novel shock-absorbing type inserted link caster device.
Background technology
Traditional inserted link castor is made up of wheel, support and inserted link.The castor be made up of wheel and support to be assigned in the sleeve that carrier presets by inserted link and is attached to below carrier.
Castor is walked on the ground, and the unfairness on ground makes the castor in walking produce to beat, and the dynamics of beating is delivered to carrier by inserted link, and the steady movement directly affect carrier makes carrier generation rock or collide, the effect of the steady movement of out of reach.
In order to meet the requirement of the firm safety of inserted link castor, be necessary to design novel inserted link caster device, a kind of shock absorption device structure, thus avoid the shortcoming that traditional inserted link castor exists.
Summary of the invention
Technical matters to be solved by this invention, just be to provide a kind of shock-absorbing type inserted link caster device, original inserted link castor basis has installed a set of U-shaped shock absorption device additional, what produce when walking when castor beats by being cushioned during U-shaped shock absorption device and damping, carrier is reduced when mobile rock or collide, more steadily and safety, the carrier that the present invention is applicable to below the Caster of below wheel diameter 100mm, 75 kilograms of loads is installed and used.
Solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of shock-absorbing type inserted link caster device, comprise inserted link castor 10, described inserted link castor 10 comprises wheel 1, support 2, inserted link 3 and jump ring 4; Wheel 1 fills in aggregates by bow 2 bottom of axle bearing down in middle groups, inserted link 3 is welded on support 2 top, and jump ring 4 is fixedly set in inserted link 3 top; It is characterized in that: be also provided with shock absorption device 11, it comprises intubate 5, U-shaped frame 6, Compress Spring 7 and set pin 8; Described intubate 5 is the metallic tubular members that an internal diameter is greater than inserted link 3, described U-shaped frame 6 is one curve U-shaped metal strip tabular component, its two end plates face respectively has the hole coordinating intubate 5 external diameter size, described U-shaped frame 6 is contained in intubate 5 by two ends perforate, Compress Spring 7 is enclosed within outside the intubate 5 between U-shaped frame 6 two ends, is fixed with set pin 8 bottom Compress Spring 7; Described shock absorption device 11 is sleeved on the inserted link 3 of inserted link castor 10 by intubate 5.
The centre of described U-shaped frame 6 has two mounting holes 9, can other carriers of connection.
Beneficial effect: the invention provides that a kind of structure is simple, compact, easy for installation, firmly shock-absorbing type inserted link caster device, original inserted link castor basis has installed a set of U-shaped shock absorption device additional, what produce when walking when castor beats by being cushioned during U-shaped shock absorption device and damping, carrier is reduced when mobile rock or collide, more steady and safety.
Accompanying drawing explanation

Fig. 2 is the inserted link Castor structure schematic diagram of apparatus of the present invention.
In figure: 1-wheel, 2-support, 3-inserted link, 4-jump ring, 5-intubate, 6-U type frame, 7-Compress Spring, 8-set pin, 9-mounting hole, 10-inserted link castor, 11-shock absorption device.
Detailed description of the invention
As shown in Figure 1-2, a kind of shock-absorbing type inserted link caster device, comprises inserted link castor 10 and shock absorption device 11, it is characterized in that: described inserted link castor 10 comprises wheel 1, support 2, inserted link 3 and jump ring 4; Support 2 fills in aggregates by wheel shaft in wheel 1 middle groups, and inserted link 3 is welded on support 2 top, and jump ring 4 is fixedly set in inserted link 3 top;
Described shock absorption device 11 comprises intubate 5, U-shaped frame 6, Compress Spring 7 and set pin 8; Described intubate 5 is the metal cylinder tubulose component of a diameter slightly larger than inserted link 3, described U-shaped frame 6 is a U-shaped metal strip tabular component, its top, two long limits respectively has the hole of intubate 5 diameter, after described intubate 5 is set with Compress Spring 7, two ends are in aggregates by U-shaped frame 6 two long limit perforate suits again, set pin 8 is fixed with bottom Compress Spring 7, change set pin in the position of spring by torsional spring, pressure fine setting is carried out to spring;
Described shock absorption device 11 is sleeved on by intubate 5 inserted link 3 of inserted link castor 10 to be assembled in aggregates, and the jump ring 4 in inserted link 3 plays the effect fixing with intubate, thus forms a kind of shock-absorbing type inserted link castor with shock absorption device.
The bottom of described U-shaped frame 6 has two mounting holes 9.
Described mounting hole 9 can install other carriers.
U-shaped frame 6 and Compress Spring 7 are fixed in intubate 5 by set pin 8, the effect that U-shaped frame 6 plays fixing inserted link castor 10 and compresses Compress Spring 7.After U-shaped frame 6 is undertaken connecting installed by mounting hole 9 and carrier, the weight of carrier and load are compressed Compress Spring 7 by the upper end of U-shaped frame 6, and Compress Spring 7 defines a kind of bounce-back state.
Due to the unfairness on road surface, cause inserted link castor 10 in advancing, produce upper and lower beating, this dynamics of beating is delivered in the intubate 5 of shock absorption device 11 by the inserted link 3 of castor, intubate 5 moves up and forces Compress Spring 7 to produce larger compression thus bounce-back, serve the effect of damping vibration, reach the effect of damping.
The present invention is simple and reasonable, and easily produce and install, shock absorption device easily keeps in repair or replaces, and the carrier being applicable to below the Caster of below wheel diameter 100mm, 75 kilograms of loads is installed and used.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not limited by the examples; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
