Abstract
The utility model relates to a self-locking device of a lifting worktable. The self-locking device comprises a shell, a pawl, a spring and a rack. The shell is arranged on a stand column. The head of the pawl is clamped at a notch of the rack. The rack is arranged on the side wall of a lifting pipe. The tail of the pawl is provided with a backstop operating lever. The spring which is in press fit with the head of the pawl is further arranged in the shell. The self-locking device of the lifting worktable has the advantages that the structure is compact, the self-locking effect is good and the safety in the lifting operation of the worktable can be effectively guaranteed.
Description
Technical field
The utility model relates to a kind of self-locking device, is a kind of self-locking device of self-powered platform specifically.
Background technology
More existing apparatus for automatically lifting adopts air pump to realize lifting and prevents the effect that bench board drops, but 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, self-locking device exists, the purpose of this utility model is to provide a kind of compact conformation, the self-locking device of a kind of self-powered platform that self-locking is effective.
The technical solution adopted in the utility model is: a kind of self-locking device of self-powered platform, its technical characterstic is: comprise housing, ratchet, spring and tooth bar, described housing is located on column, the pawl head of described ratchet is stuck on the tooth mouth of tooth bar, described tooth bar is located at the fall way sidewall, the afterbody of ratchet is provided with the retaining joystick, also is provided with the spring of pressing ratchet pawl head in housing.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: 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 fall way rising stopped, ratchet pawl head is static being stuck in the tooth mouth under the effect of spring, avoids tooth bar to glide and make tool shelf decline cause contingency, improved the bench board usage safety performance.
Description of drawings
Fig. 1 is the utility model structural representation.
In figure: fall way 1, tooth bar 2, ratchet 3, column 4, housing 5, spring 6, retaining joystick 7.
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 self-locking device of self-powered platform, comprise housing 5, ratchet 3, spring 6 and tooth bar 2, housing 5 is located on column 4, is provided with ratchet 3, spring 6 and retaining joystick 7 in housing 5, the afterbody of ratchet 3 is provided with retaining joystick 7, fall way 1 sidewall is provided with tooth bar 2, and the pawl head of ratchet 3 is stuck on the tooth mouth of tooth bar 2, and the pawl head of ratchet 3 is stuck on the tooth mouth of tooth bar 2, spring 6 one ends are fixed in housing 5, and spring 6 other ends are pressed on ratchet 3 pawl heads.
When fall way 1 rises, 3 of the ratchet pawls that fall way 1 tooth bar 2 tooth mouths will be stuck in the tooth mouth upwards pull away the tooth mouth, reset of card is to next tooth mouth under the effect of spring 6 for ratchet 3 pawl heads, and tooth bar 2 teeth are salty upwards pulls away the tooth mouth with ratchet 3 pawl heads again, and fall way 1 can normally rise; After fall way 1 rising stopped, ratchet 3 pawl heads static being stuck in the tooth mouth under the effect of spring 6 avoided tooth bar 2 downslides that fall way 1 decline is caused and contingency improved usage safety performance.
