Also referring to Fig. 1 to Fig. 7, now track fixed connection structure provided by the utility model is illustrated.It is a kind of Track fixed connection structure, comprising:

Two tracks 1 being mutually butted, the bottom of two tracks 1 is respectively equipped with card slot 11；

It is supported in 1 lower section of track and sets the bottom plate 2 there are two fixture block 21, two fixture blocks 21 are inserted into two card slots 11 respectively In；And

Two limit plates 3 connecting with bottom plate 2, two limit plates 3 are located at 1 two sides of track, and each limit plate 3 is equal For the outside face contact respectively with two tracks 1.

Compared with prior art, the utility model track fixed connection structure passes through the fixture block 21 and track 1 on bottom plate 2 Card slot 11 is clamped, so that the end of two tracks 1 is fixedly connected and mutual right in the up-down direction on the extending direction of track 1 It is quasi-；By being located at the limit plate 3 of 1 two sides of track, guarantee to be mutually aligned and will not misplace in two side direction of end of track 1.Bottom plate 2 The active force in 1 extending direction of track and the support force to track 1 between two tracks 1 are undertaken, and limit plate 3 undertakes two tracks 1 In the active force of two side directions, bottom plate 2 and the respective stress condition of limit plate 3 are improved, so that track fixed connection structure Structure is more stable, is not likely to produce gap between two 1 connectors of track, the service life is longer.

Further, suitable material can also targetedly be selected according to bottom plate 2 and the respective stress condition of limit plate 3 Material further increases the stability of structure.

Specifically, card slot 11 is offered on the bottom surface of two respective ends of track 1.Bottom plate 2 is to be fixed on datum level Plate, datum level can be the top surface of bottom surface or support frame, and two fixture blocks 21 are welded on the top surface of bottom plate 2.Two tracks 1 End be placed on the top surface of bottom plate 2, two fixture blocks 21 are inserted into two card slots 11 respectively so that bottom plate 2 respectively with two rails Road 1 is clamped on the extending direction of track 1.More specifically, length and fixture block 21 of the card slot 11 on 1 extending direction of track are in-orbit Length on 1 extending direction of road is identical, so that bottom plate 2 and track 1 connect and fix on the extending direction of track 1, two tracks 1 End be mutually butted.Two limit plates 3 are fixedly mounted on the top surface of bottom plate 2, and are located at the two sides of two tracks 1. Each limit plate 3 is used to the outside face contact with two tracks 1 respectively, for limiting the lateral displacement of two tracks 1.More Body, limit plate 3 is plate, and the plate face at 3 both ends of limit plate is bonded with the outside wall surface of two 1 side walls of track respectively, so that two The end of track 1 is able to maintain face.

Further, referring to Figure 2 together to Fig. 4, as track fixed connection structure provided by the utility model one Kind specific embodiment, the spacing of 1 liang of outside wall surface of track are gradually reduced from top to bottom

Further, referring to Figure 2 together to Fig. 4, as track fixed connection structure provided by the utility model one Kind specific embodiment, the width of 11 groove bottom of card slot are greater than the width of 1 bottom surface of track, the top surface of fixture block 21 and the slot of card slot 11 Bottom surface abuts.Increase the area contacted between fixture block 21 and track 1, the stress reduced between track 1 and bottom plate 2 is concentrated.

For the track 1 that the spacing of two outside wall surfaces is gradually reduced from top to bottom, such as two outside wall surfaces are V-shaped or the rail of U-shaped The bottom in road 1, track 1 is pointed, if the pointed bottom of track 1 is directly contacted with bottom plate 2, contact area is smaller, 1 bottom surface of track Stress is concentrated between bottom plate 2, is easy to cause track 1 or bottom plate 2 to deform, track 1 collapses downwards, makes to be formed between two tracks 1 Gap, and if two tracks 1 collapse degree difference, can also make to form drop at the docking of two tracks 1, cause bigger safety Hidden danger.

Specifically, since the bottom of track 1 is pointed, the pointed bottom of track 1 is cut into a part and forms card slot 11, is made The width for obtaining 11 groove bottom of card slot is greater than the width of 1 bottom surface of track, when the area of 11 groove bottom of card slot is greater than not set card slot 11 The area of 1 bottom corresponding portion bottom surface of track, the top surface of fixture block 21 are abutted with the groove bottom of card slot 11, avoid card slot 11 and bottom plate Stress between 2 is concentrated.

Further, also referring to Fig. 1 to Fig. 4 and Fig. 7, as track fixed connection structure provided by the utility model A kind of specific embodiment, track 1 is equipped with guide groove 12, and card slot 11 is connected to the slot bottom of guide groove 12, the top surface of fixture block 21 with lead The groove bottom of slot 12 is concordant.For the device run on track 1 when by the joint of track 1, the idler wheel of device is directly and fixture block 21 top surface contact, reduces device to the pressure of 1 end of track, avoids the end of two tracks 1 due to the pressure of receiving is excessive Mutual dislocation.

Further, referring to Figure 2 together to Fig. 4, as track fixed connection structure provided by the utility model one Kind specific embodiment, the section of track 1 are V-shaped.

Specifically, two outside wall surfaces of track 1 are V-shaped, and track 1 is equipped with 32 upward V-arrangement guide grooves 12 of opening, so that track 1 Section it is V-shaped.The pointed bottom of track 1 is cut into a part and forms card slot 11, the depth of card slot 11 makes the slot of card slot 11 Bottom surface is just connected to the groove bottom of 1 upper guide groove 12 of track, so that after the fixture block 21 on bottom plate 2 is inserted into card slot 11, fixture block 21 Top surface abutted with the groove bottom of card slot 11, while the top surface of fixture block 21 is concordant with the groove bottom of guide groove 12, so that the rolling of device When wheel is run in V-shaped groove, it can contact and roll across with the top surface of fixture block 21.Through-hole can also be opened up in the bottom surface of guide groove 12 makes It obtains guide groove 12 to be connected to card slot 11, when so that the idler wheel of device being run in V-shaped groove, can contact and roll with the top surface of fixture block 21 It crosses.

When card slot 11 is connected to the slot bottom of guide groove 12, the groove bottom of card slot 11 includes being located at 1 side wall lower ends of track On two bearing surfaces 13, the width that the width of above-mentioned 11 groove bottom of card slot is greater than 1 bottom surface of track is interpreted as two abuttings The sum of the width in face 13 is greater than the width of 1 bottom surface of track.Specifically, it is connected in the groove bottom of card slot 11 with the slot bottom of guide groove 12 When, card slot 11 cuts the side wall lower ends of track 1, so that the groove bottom of card slot 11 is formed in the lower end of 1 two sidewalls of track respectively Two bearing surfaces 13, the top surface of fixture block 21 with abutted respectively with two bearing surfaces 13.The sum of the width of two bearing surfaces 13 is greater than The width of 1 bottom surface of track, so that the stress between card slot 11 and bottom plate 2 is avoided to concentrate.
