Abstract

The utility model relates to a pin coupling device, comprising a stud and anti-loosing pin, wherein four or many groves (4) are symmetrically opened on one end of the stud (1) and a smooth pole (5) and a screw pole (6) are arranged on another end and during assembling, the pin with the groove is fixed in a shell (3) and then the anti-loosing pin is mounted into the groove between the stud and the shell to form the solid included angle. The pin coupling device well solves the problems of the stud that the stud easily looses during assembly, the fastening is not good and the stud easily rotates and the stud goes against disassembly and repair. The pin coupling device has features of increased work reliability, lighter and more reasonable design, increased assembly, repair efficiency of the shell, reduces cost, simultaneous formation of series standards, convenient promotion and use and is suitable for the aluminum, steel bodies in the situation with relative large outside function shake.

Description

Band pin coupling arrangement

Technical field: the utility model relates to the band pin assembly, particularly a kind of band pin coupling arrangement.

Background technique: the use of stud is very general, structure is also varied, it is to realize locking by tightness cooperation, screw-thread fit etc. that common stud is installed, on locking device, be short of tightness, this kind mode is promptly had relatively high expectations to element precision, easily cause part to scrap again, guarantee reliability requirement under the strong motion environment so use such structure to be difficult in.

Summary of the invention: the utility model purpose is to provide a kind of band pin coupling arrangement, and this device is fine to have solved that stud is easily loosening at fit on, bad, the easy rotation of tightness, be unfavorable for problem such as dismounting maintenance.

Formation of the present utility model: form by stud and locking latch, an end symmetry has four troughs on the stud, and the other end is smooth shaft and threaded stem, is fixed in the housing with the stud that has trough during assembling, then locking latch is packed in the trough between stud and the housing, form the entity angle.

A locking latch part is a trapezoidal entity, and another part is the entity of a flat, and flat entity face is greater than trapezoidal entity face, and trapezoidal faces is smaller or equal to the stud groove width, and flat entity face is more than or equal to groove width, and these three sizes are cooperated by tolerance range.

Trough number on the stud can be for a plurality of.

Compared with the prior art, the utility model is fine to have solved that stud is easily loosening at fit on, bad, the easy rotation of tightness, be unfavorable for problem such as dismounting maintenance, has improved functional reliability, and design is exquisite more, reasonable, assembling, the maintenance efficiency of housing have also been improved, the reduction expense.Can form series standard simultaneously, be convenient to promote the use of.

Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is a trough of belt stud structural drawing, and Fig. 3 is the left view of Fig. 2, and Fig. 4 is locking latch structure figure, and Fig. 5 is the worm's eye view of Fig. 4, and Fig. 6 is the A-A sectional view of Fig. 4.

1. studs among the figure, 2. locking latch, 3. housing, 4. trough, 5. smooth shaft, 6. threaded stem.

Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, form by stud and locking latch, an end symmetry has four troughs 4 on the stud 1, the other end is smooth shaft 5 and threaded stem 6, be fixed in the housing 3 with the stud that has trough during assembling, then locking latch is packed in the trough between stud and the housing, form the entity angle.

Locking latch 2 parts are trapezoidal entities, and another part is the entity of a flat, and flat entity face is greater than trapezoidal entity face, and trapezoidal faces is smaller or equal to the stud groove width, and flat entity face is more than or equal to groove width, and these three sizes are cooperated by tolerance range.

Trough number on the stud 1 can be for a plurality of.

Claims

1. a band is sold coupling arrangement, form by stud and locking latch, it is characterized in that: the last end symmetry of stud (1) has four troughs (4), the other end is smooth shaft (5) and threaded stem (6), be fixed in the housing (3) with the stud that has trough during assembling, then locking latch is packed in the trough between stud and the housing, form the entity angle.

2. band pin coupling arrangement according to claim 1, it is characterized in that: locking latch (a 2) part is a trapezoidal entity, another part is the entity of a flat, flat entity face is greater than trapezoidal entity face, and trapezoidal faces is smaller or equal to the stud groove width, flat entity face is more than or equal to groove width, and these three sizes are cooperated by tolerance range.

3. band pin coupling arrangement according to claim 1 is characterized in that: the trough number on the stud (1) can be for a plurality of.
