Abstract
The utility model discloses a locking device for front and back adjustment of a forklift steering wheel. The locking device comprises a locking bolt, a locking nut, a steering tubular column support, a steering tubular column and a handle fixedly connected with the locking nut. A horizontal installation support is arranged on a steering tubular column, an internal thread groove hole is arranged at one end, close to the steering tubular column support, of the installation support, the locking nut, the steering tubular column support and the installation support sequentially screw together and penetrate through the locking bolt and the bottom of the locking bolt is in screw fit in the bottom of the internal thread groove hole of the installation support. The locking device can adjust the front and back position of the steering wheel without overcoming large friction force, reduces labor intensity of a user, improves adjustment efficiency, meets requirements of different users for operation space, improves operation comfortableness, simultaneously simplifies structure, reduces production cost and improves production efficiency.
Description
Technical field
The utility model is regulated the latching device field of using before and after relating to bearing circle, specifically regulates before and after a kind of forklift steering wheel and uses latching device.
Background technology
Regulation locking device adopts revolution to slide before and after the bearing circle of at present client's use, and jam nut is locked the front and back of realizing bearing circle and regulated.Owing to considering between steering column support and the steering column in the reason aspect accuracy of manufacture and the assembling reasonableness, in the maximum gap of leaving 2mm between two plates on the project organization, and the pitch of jam nut is 1.5mm, jam nut is locked and is unclamped and can only rotate half-turn, be jam nut in the displacement that axially can only realize 0.75mm, can't realize locking.Used larger predetermincd tension to allow the steering column support that predeformation has occured in order to realize being locked at when assembling, so jam nut need larger strength when unclamping with locking.
The utility model content
The technical problems to be solved in the utility model provides a kind of forklift steering wheel front and back adjusting latching device, its, in the situation that do not affect setting range before and after the bearing circle, simplified the structure of device and Effective Raise and regulated the operation comfort of efficient and fork truck before and after equipment safety reliability, the bearing circle.
The technical solution of the utility model is:
Regulate before and after the forklift steering wheel and use latching device, the handle of include lock bolt, jam nut, steering column support, steering column, captiveing joint with jam nut, be provided with the mounting bracket of level on the described steering column, one end of the contiguous steering column support of mounting bracket is provided with the negative thread slotted eye, jam nut, steering column support and mounting bracket screw togather successively and pass lock bolt, and the bottom of lock bolt is screwed into the bottom of mounting bracket negative thread slotted eye.
The bottom of described mounting bracket negative thread slotted eye is provided with stop nut.
Advantage of the present utility model:
The utility model does not need to make steering column support generation predeformation without the need for predetermincd tension yet, and only need to stay very little gap when assembling because considering that accuracy of manufacture and assembling reasonableness reserve the gap between steering column and the steering column support.When the pitch of lock bolt is 1.5mm, approximately only need to rotate about 100 ° and can produce moving axially of 0.4mm, the locking that is used for realizing latching device with unclamp.Need not to overcome the adjusting that larger friction force can be finished the bearing circle front and back position during the utility model operation, reduced user's labour intensity, improved adjusting efficient, satisfied the requirement of Different Individual user to manipulation space, improved operation comfort.Simultaneously, the structure of simplification also is conducive to reduce production costs, and enhances productivity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, regulate before and after the forklift steering wheel and use latching device, the handle 5 of include lock bolt 1, jam nut 2, steering column support 3, steering column 4, captiveing joint with jam nut 2; Be provided with the mounting bracket 6 of level on the steering column 4, one end of mounting bracket 6 contiguous steering column supports 3 is provided with the negative thread slotted eye, the bottom of negative thread slotted eye is provided with stop nut 7, and the stop nut 7 that jam nut 2, steering column support 3 and mounting bracket 4 screw togather in the bottom of passing lock bolt 1 and lock bolt 1 and the negative thread slotted eye successively screws togather.
When needs are regulated the bearing circle front and rear angles, pulling handle 5 left-hand revolution certain angles, this moment, jam nut 2 unclamped, and thrust reduces, and steering column 4 separates with steering column support 3, regulates the front and back position of bearing circle by the pulling bearing circle; Regulate 5 rotations of complete rear cw pulling handle to regulating front position, this moment, steering column 4 compressed again with steering column support 3, and end is adjusted in the steering wheel position locking.
Claims (2)
