Abstract
The utility model discloses an oil cylinder pin with a self-locking structure. The oil cylinder pin with the self-locking structure comprises an oil cylinder pin body and an oil cylinder pin head, wherein the oil cylinder pin head and the oil cylinder pin body are connected in a threaded mode and the oil cylinder pin body is provided with an installment groove. The oil cylinder pin with the self-locking structure further comprises a clamping block, wherein the clamping block is matched with the installment groove and an elastic protrusion protrudes out from an outer wall of the oil cylinder pin. The oil cylinder pin with the self-locking structure not only achieves axial spacing of a position in which the oil cylinder pin and the oil cylinder pin seat are matched, ensures safety of equipment, but also achieves radial elastic contact of the oil cylinder pin and the oil cylinder pin seat, prolongs service lives of the oil cylinder pin and the oil cylinder pin seat, and can be quickly disassembled.
Description
Technical field
The utility model relates to oil cylinder pin technical field.
Background technique
Hydraulic jack can't closely cooperate owing to form the gap between oil cylinder pin and the oil cylinder key seat in use, causes that cooperation position becomes flexible easily in long-time situation about using, and the oil cylinder pin usually is that rigidity contacts with the oil cylinder key seat, and stressed is to cause easily wearing and tearing.
The model utility content
The utility model provides a kind of oil cylinder pin with self-locking structure, both realized the axial limiting to the cooperation place of oil cylinder pin and oil cylinder key seat, guaranteed the Security of equipment, oil cylinder pin and oil cylinder key seat Elastic Contact have radially been realized again, prolonged the working life of oil cylinder pin and oil cylinder key seat, and can quick-detachment.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of oil cylinder pin with self-locking structure comprises oil cylinder pin body and oil cylinder plunger section,
Described oil cylinder plunger section is threaded with oil cylinder pin body,
Be provided with mounting groove on the described oil cylinder pin body,
Also comprise fixture block, described fixture block cooperates with described mounting groove, and fixture block upper end elastic bumps protrudes from oil cylinder pin body outer wall.
Further, described fixture block comprises elastic bumps and square deck, and elastic bumps is long strip, and an end and square deck are fixed together, and free end raises up, and the height of described free end projection is higher than the upper plane of square deck.
Further, described fixture block has four.
Further, described mounting groove shape is corresponding with the shape of fixture block after the elastic bumps of described fixture block is adequately compressed.
Further, described mounting groove has four, and per two one group, every group of mounting groove is along oil cylinder pin body axial distribution, and two groups of mounting groove positions take oil cylinder pin body axis as axle axisymmetricly.
The utility model by to the design of fixture block, mounting groove so that spacing on not only can realizing axially of oil cylinder pin, and then realization auto-lock function, guaranteed the Security of equipment, and can realize the oil cylinder pin that makes progress of footpath and the Elastic Contact of oil cylinder key seat, alleviate the wearing and tearing between the two, prolonged the working life of oil cylinder pin and oil cylinder key seat.Realized the quick-detachment of oil cylinder pin by oil cylinder plunger section and being threaded of oil cylinder pin body.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the described a kind of oil cylinder pin structure schematic representation with self-locking structure of the utility model embodiment.
Embodiment
As shown in Figure 1, the described a kind of oil cylinder pin with self-locking structure of the utility model embodiment comprises oil cylinder pin body 1 and oil cylinder plunger section 2,
Oil cylinder plunger section 2 is threaded with oil cylinder pin body 1,
Be provided with mounting groove on the oil cylinder pin body 1,
The utility model also comprises fixture block 4, and fixture block 4 cooperates with mounting groove, and fixture block 4 upper end elastic bumps 41 protrude from oil cylinder pin body 1 outer wall.
Fixture block 4 has four.
The mounting groove shape is corresponding with the shape of fixture block 4 after the elastic bumps 41 of fixture block 4 is adequately compressed.
Mounting groove has four, and per two one group, every group of mounting groove is along oil cylinder pin body 1 axial distribution, and two groups of mounting groove positions take oil cylinder pin body 1 axis as axle axisymmetricly.
The utility model in use, oil cylinder pin body 1 is connected with oil cylinder plunger section 2, fixture block 4 is installed in the mounting groove 3, then the oil cylinder pin is inserted in the oil cylinder key seat, in the oil cylinder key seat, be provided with draw-in groove, before the elastic bumps 41 on the oil cylinder pin arrives the draw-in groove position, elastic bumps 41 is pushed by the oil cylinder key seat, when arriving the slot postpones, the elastic bumps 41 on the oil cylinder pin cooperates with draw-in groove in the oil cylinder pin card seat, the oil cylinder pin is realized self-locking, in the time the oil cylinder pin will being pulled down, then first oil cylinder plunger section 2 is disassembled, then the side from original installation oil cylinder plunger section 2 pushes hard oil cylinder pin body 1, just oil cylinder pin body 1 can be unloaded.
The utility model by to the design of fixture block, mounting groove so that spacing on not only can realizing axially of oil cylinder pin, and then realization auto-lock function, guaranteed the Security of equipment, and can realize the oil cylinder pin that makes progress of footpath and the Elastic Contact of oil cylinder key seat, alleviate the wearing and tearing between the two, prolonged the working life of oil cylinder pin and oil cylinder key seat.Realized the quick-detachment of oil cylinder pin by oil cylinder plunger section and being threaded of oil cylinder pin body.
