Abstract
The utility model relates to a workbench lifting device, which comprises a shell, a gear and a pawl, wherein the gear and the pawl are arranged inside the shell, and the shell is arranged on a stand column; a lifting tube is sleeved in the stand column, and a rack is arranged on the side wall of the lifting tube; the gear is meshed with the rack, and the tail of the pawl is provided with a retaining joystick; and the head of the pawl is stuck in the mouth of the rack. The device provided by the utility model has the advantages of compact structure, convenience in lifting, high security performance and low failure rate.
Description
Technical field
The utility model relates to a kind of jacking system, relates in particular to a kind of jacking system of bench board.
Background technology
When servicing a car, the height of table of place tool needs to regulate at any time to satisfy maintenance requirements, and the jacking system of conventional table can only be in the situation that comparatively inconvenience by manual adjustment, be used in zero load.Existing apparatus for automatically lifting adopts air pump to realize the lifting effect more, and air pump is changed, the maintenance trouble, and cost is high.
Summary of the invention
In order to solve many defectives that in prior art, jacking system exists, the purpose of this utility model is to provide a kind of compact conformation, lifting is convenient, safety performance is high, the jacking system of a kind of bench board of failure rate is low.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of jacking system of bench board, its technical characterstic is: comprise housing, gear and ratchet, described gear and ratchet are located at enclosure interior, and described housing is located on column, and fall way is placed in column, the fall way sidewall is provided with tooth bar, the wheel and rack engagement, the afterbody of ratchet is provided with the retaining joystick, and the pawl head of ratchet is stuck on the tooth mouth of tooth bar.
Also be provided with the spring of pressing ratchet pawl head in this jacking system housing.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: gear is provided with rotating handles, when fall way must rise, shake rotating handles, the gear transmission tooth bar rises fall way, continues in uphill process at tooth bar, and the ratchet pawl head that the rack tooth mouth will be stuck in the tooth mouth upwards pulls away the tooth mouth, tooth bar is not affected by ratchet pawl head, and fall way can normally rise; When fall way must descend, the retaining joystick of leaving behind unclamps ratchet made ratchet pawl head break away from the tooth mouth of tooth bar, oppositely shakes rotating handles, the gear transmission tooth bar descends fall way, in tooth bar continuous decrease process, ratchet pawl head descends without impact on tooth bar, and fall way can normally descend; Descending operation is simple, convenient, time saving and energy saving; By rotating handles operation gear driven gear rack elevating, compact conformation, the mechanical elevating reliable in structure, failure rate is low, easy to maintenance, long service life.
Be provided with the spring of pressing ratchet pawl head in jacking system, when fall way rises, the ratchet pawl head that fall way rack tooth mouth will be stuck in the tooth mouth upwards pulls away the tooth mouth, ratchet pawl head under the effect of spring reset of card to next tooth mouth, rack tooth is salty upwards pulls away the tooth mouth with ratchet pawl head again, and fall way can normally rise; After the tool shelf rising stopped, ratchet pawl head is static being stuck in the tooth mouth under the effect of spring, avoids the tooth bar downslide to cause and contingency improved usage safety performance.
Description of drawings
Fig. 1 is the utility model structural representation.
In figure: fall way 1, housing 2, tooth bar 3, column 4, gear 5, rotating handles 6, ratchet 7, spring 8, retaining joystick 9.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1, a kind of jacking system of bench board mainly comprises housing 2, gear 5, tooth bar 3, rotating handles 6, ratchet 7, spring 8 and retaining joystick 9, be provided with gear 5, ratchet 7 and spring 8 in described housing 2, housing 2 is located on column 4, fall way 1 is placed in column 4, fall way 1 sidewall is provided with tooth bar 3, gear 5 and tooth bar 3 engagements, gear 5 is provided with rotating handles 6, the afterbody of ratchet 7 is provided with retaining joystick 9, the pawl head of ratchet 7 is stuck on the tooth mouth of tooth bar 5, and spring 8 one ends are fixed in housing 2, and spring 8 other ends are pressed on ratchet 7 pawl heads.
When fall way 1 must rise, shake rotating handles 6, gear 5 driving racks 3 rise fall way 1, in tooth bar 3 continues uphill process, the ratchet 7 pawl heads that tooth bar 3 tooth mouths will be stuck in the tooth mouth upwards pull away the tooth mouth, and tooth bar 3 is not affected by ratchet 7 pawl heads, and fall way 1 can normally rise; When fall way 1 must descend, the retaining joystick 9 of leaving behind unclamps ratchet 7 makes ratchet 7 pawl heads break away from the tooth mouth of tooth bar 3, oppositely shake rotating handles 6, gear 5 driving racks 3 descend fall way 1, in tooth bar 3 continuous decrease processes, ratchet 7 pawl heads descend without impact on tooth bar 3, and fall way 1 can normally descend; Descending operation is simple, convenient, time saving and energy saving; Be provided with the spring 8 of pressing ratchet 7 pawl heads in housing 2, when fall way 1 rises, the ratchet 7 pawl heads that fall way 1 tooth bar 3 tooth mouths will be stuck in the tooth mouth upwards pull away the tooth mouth, ratchet 7 pawl heads under the effect of spring 8 reset of card to next tooth mouth, tooth bar 3 teeth are salty upwards pulls away the tooth mouth with ratchet 7 pawl heads again, and fall way 1 can normally rise; After fall way 1 rising stopped, ratchet 7 pawl heads static being stuck in the tooth mouth under the effect of spring 8 avoided tooth bar 3 downslides to cause and contingency improved usage safety performance.
Claims (2)
1. the jacking system of a bench board, it is characterized in that: comprise housing, gear and ratchet, described gear and ratchet are located at enclosure interior, described housing is located on column, fall way is placed in column, and the fall way sidewall is provided with tooth bar, the wheel and rack engagement, the afterbody of ratchet is provided with the retaining joystick, and the pawl head of ratchet is stuck on the tooth mouth of tooth bar.
