Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

Fig. 1-Fig. 4 is refer to, Fig. 1 provides vehicle seat fixing device a kind of structure of embodiment by the utility model Schematic diagram；Fig. 2 is the structural representation of upper end cover；Fig. 3 is the structural representation that support member and bottom end cover combine；Fig. 4 is Fig. 3 institutes Show support member and lower end cover combined structure constructed profile.

In a kind of embodiment, vehicle seat fixing device provided by the utility model, include the support of interconnection Part 2 and fixture 3, the fixture 3 include the upper end cover 32 and bottom end cover 31 being bolted, and seat rod 1 is arranged on institute State in the mounting groove that upper end cover 32 is formed with the bottom end cover 31；The support member 2 be both ends open tubular structure, its one end Affixed with bottom end cover 31, the bolt is through fixing the upper end cover 32 and the bottom end cover 31 inside the support member 2.It is above-mentioned In structure, including upper end cover 32, bottom end cover 31 and support member 2, wherein upper end cover 32 and bottom end cover 31 are bolted to be formed Fixture 3 with mounting groove, the fixture 3 are used to fix with vehicle seat, and seat rod 1 is arranged in mounting groove, passes through bolt Constantly locking, now seat rod 1 is firmly fixed in mounting groove, so as to complete the fixation of vehicle seat, while the one of support member 2 End is affixed with bottom end cover 31, and support member 2 is tubular structure, and both ends open, wherein one end pass through the modes such as welding with bottom end cover 31 Affixed, when upper end cover 32 is bolted with bottom end cover 31, bolt needs to enter support member 2 from the opening of support member 2 Inside, bolt are being threadedly coupled after bottom end cover 31 with upper end cover 32.Using this kind of mode, fixing device is on the one hand realized Effective fixation to vehicle seat, upper end cover 32 and bottom end cover 31 are locked so as to which vehicle seat is securely fixed in mounting groove by bolt, no Occur and rock up and down, locking effect is good, and on the other hand, clamping screw belongs to concealed structure, due to general support member 2 The other end (one end is affixed with bottom end cover 31) is connected with vehicle frame, and outside can not find bolt, so as to effectively antitheft.

It is further understood that, the bottom end cover 31 is provided with bolt hole 311, the bolt hole 311 and the branch The inside of support member 2 is connected, and the bolt is threadedly coupled by the bolt hole 311 with the upper end cover 32.In said structure, Bolt hole 311 is offered on bottom end cover 31, the bolt hole 311 is connected with the inside of support member 2, i.e., the bolt hole 311 is opened It is located on the connecting end surface of support member 2 and bottom end cover 31, first enters bolt from the openend of support frame during installation, by bolt The end of thread passes through bolt hole 311, now offers screwed hole 322 on the end face that upper end cover 32 and bottom end cover 31 coordinate, should Screwed hole 322 does locking processing, and the bolt thread through bottom end cover 31 enters upper end cover 32, effectively will be upper by screwing bolts End cap 32 and bottom end cover 31 are fixed, and the bolt of now installation is completely in the inside of structure, and outside can not find installation Removed position, therefore this kind of mounting means is concealed, so as to effectively play antitheft effect.

Further, be set with elastomeric pad on the bolt, the elastomeric pad be arranged on the nut of the bolt with Between the bottom end cover 31.In said structure, spring leaf is set with the stud before bolt installation in bolt, when bolt passes through Behind the inside of support member 2, screw rod passes through bolt hole 311, and in screw rod rotary course, nut promotes elastomeric pad towards bottom end cover 31 motions, automatically after the completion of locking, nut promotes elastomeric pad to be resisted against on bottom end cover 31.Because elastomeric pad will in bolt After the completion of locking elastic deformation occurs for upper end cover 32 and bottom end cover 31, the elastic deformation effectively prevent bolt due to for a long time by The influence of the factors such as power and occur loosening and then cause the phenomenon that part comes off to occur.

Specifically understand, the quantity of the mounting groove is two, and two mounting grooves are placed in the both sides of the bolt. The quantity of mounting groove is two in the structure, and its arrangement is respectively to set one in the both sides of bolt, this kind of set-up mode and On the one hand it is not in rocking up and down that the design of the quantity of mounting groove enables to vehicle seat, and the steady of vehicle seat has been effectively ensured Qualitative, this kind of mode locking effect is good, limit effect is good；Another aspect mounting groove is arranged on the both sides of bolt, is effectively ensured The stress balance of vehicle seat, especially in user's driving conditions, due to user, in driving, bipod is alternately had an effect, the buttocks of user Vehicle seat can be caused to shake, if single-sided design is easy to stress concentration occur to be broken, and then influence traffic safety, Now designed for both sides, this kind of mode uniform force, stress concentration will not be produced, and then the safety of driving has been effectively ensured.

Specifically, the mounting groove includes upper half groove 321 and lower half groove 312, and the upper half groove 321 is opened in the upper end On lid 32, the lower half groove 312 is opened on the bottom end cover 31.In said structure, upper half groove is offered on upper cover plate 321, its lateral cross section is semicircle, and lower half groove 312 is offered on lower cover, and its lateral cross section is semicircle, when in vehicle seat When bar 1 carries out installing fixed, upper half groove 321 is bonded with the top outer circumference surface of seat rod 1, under lower half groove 312 and seat rod 1 Portion's outer circumference surface fitting, upper half groove 321 and lower half groove 312 form mounting groove, and the cross section of the mounting groove is circle, and its diameter is small In the diameter of section of seat rod 1, by the locking of bolt, the spacing between upper half groove 321 and lower half groove 312 constantly reduces, car Seat bar 1 is by progressively limiting locking in mounting groove, and with upper half groove 321 and lower half groove 312, distance further subtracts between the two Small, seat rod 1 is finally limited in the mounting groove of locking.The structure, two are screwed with bolt by two halves formula trough body structure The distance between person is less and less, and in the mounting groove for finally effectively fixing seat rod 1, this kind of mode is simple in construction, locking limit The effect of position is good, effectively meets the use demand of user.

Further, the first raised texture is provided with the upper half groove 321, second is provided with the lower half groove 312 Raised texture.The structure is provided with the first raised texture in upper half groove 321, and raised texture is provided with lower half groove 312, the One raised texture and the second raised texture play a part of increasing friction force to the outer circumference surface of seat rod 1 respectively so that vehicle seat Bar 1 will not rotate, so as to be further ensured that locking effect.

It is pointed out that the pattern of the first raised texture and the second raised texture is crossing net check network, also may be used certainly Think that other forms, then this application repeat no more.

The utility model also provides a kind of shared bicycle for including above-mentioned vehicle seat fixing device, and other of the shared bicycle are each Part-structure refer to prior art, will not be repeated here.
