Referring to fig. 1 and 2, a rail clamping device according to a preferred embodiment of the present utility model includes a rail 100, a rail clamping box 200 and a clamping tongue 300.

The upper end of the track 100 is provided with a plurality of clamping structures at intervals along the length direction; the rail clamping box 200 is slidably mounted on the rail 100 so as to be slidable along the length direction of the rail 100; the clamping tongue 300 is eccentrically and rotatably installed on the clamping rail box 200, and the eccentric end of the clamping tongue 300 is provided with a resisting end face 310, wherein the resisting end face 310 is used for being abutted against the clamping structure. Each clamping structure is provided with two opposite pressing side walls 111 facing to each other, so that when the pressing end faces 310 are pressed against each other and the pressing end faces 310 are pressed against the pressing side walls 111 with different orientations, the relative movement direction of the rail 100 and the rail clamping box 200 can be adjusted.

It is understood that the number of tracks 100 may also be single track, double track or multiple track.

Referring to fig. 3 and 5, in some embodiments of the present utility model, the clamping structure is a clamping groove 110 disposed on an upper end surface of the track 100, the clamping groove 110 has two opposite pressing sidewalls 111 along a length direction of the track 100, and the clamping tongue 300 can rotate opposite to the pressing sidewalls 111 with different orientations on the clamping groove 110. Specifically, to ensure consistent movement cadence, adjacent card slots 110 are typically spaced apart. As shown in fig. 5, the track 100 extends in the front-rear direction, the length direction of the track 100 is the front-rear direction, the width direction is the left-right direction, and the two pressing side walls 111 are the front-rear side walls of the clamping groove 110.

Of course, in other embodiments, the detent structure may be a vertically protruding bump, so that a slot is not required to be disposed on the track 100, and the structural strength of the track 100 may be ensured.

Specifically, the clamping tongue 300 is rotatably installed on the rail clamping box 200 through a pin shaft, when the clamping tongue 300 passes through the clamping groove 110, the clamping tongue 300 can be partially embedded into the clamping groove 110 under the action of self gravity and prop against the bottom wall of the clamping groove 110, and when prop against, the blocking end face 310 is opposite to one of the propping side walls 111; the retaining end surface 310 of the latch 300 can be rotated to face the differently oriented pressing side wall 111, and the differently oriented pressing side wall 111 refers to the front pressing side wall 111 and the rear pressing side wall 111 of the latch 110. When the latch 300 is opposed to the pressing side wall 111 on the front side, the latch 300 can be opposed to the pressing side wall 111 on the rear side by rotating the latch 300. The clamping groove 110 is formed in the upper surface of the track 100, so that the influence on the structural strength of the track 100 is very small, and the structural safety is ensured; through the eccentric arrangement of the clamping tongue 300, when the clamping tongue 300 passes through the clamping groove 110, the clamping tongue 300 can be partially embedded into the clamping groove 110 under the action of self gravity and is propped against the bottom wall of the clamping groove 110, so that the automatic matching of the clamping tongue 300 and the clamping groove 110 is realized without utilizing structural members such as springs, when the clamping tongue 300 is propped against the bottom wall of the clamping groove 110, the resisting end face 310 is opposite to one of the propping side walls 111, and the resisting end face 310 is opposite to the propping side wall 111, so that acting force can be transmitted after the two are close to and propped against each other, and the relative movement of the track 100 and the track clamping box 200 is realized; when the pushing direction needs to be changed, the opposite of the pressing side walls 111 with different directions of the resisting end face 310 can be realized only by rotating the clamping tongue 300, the pin shaft does not need to be disassembled and assembled, and the operation is simpler.

In some embodiments of the present utility model, the clamping groove 110 is formed by recessing the upper end surface of the rail 100.

Of course, in other embodiments, the clamping groove 110 may be defined by two protruding structures on the upper end surface of the track 100, where one clamping groove 110 is defined between two adjacent protruding structures, and the protruding structures do not affect the structural strength of the track 100 compared to the clamping groove 110 formed by reducing the material on the track 100.

Referring to fig. 3 and 4, in some embodiments of the present utility model, the eccentric end of the latch 300 has an abutment surface 320 at two sides of the abutment surface 310, and when the abutment surfaces 320 at two sides are respectively abutted against the bottom wall of the slot 110, the abutment surface 310 is respectively opposite to the two abutment side walls 111 with different orientations. When the engaging surface 320 engages the bottom wall of the slot 110, the engaging surface is sufficient to prevent the corner stress from concentrating and colliding with, which may result in easy damage to the structure.

Referring to fig. 4, in a further embodiment of the present utility model, both sides of the resisting end surface 310 are provided with outwardly tilted surfaces 311, and an included angle formed by the tilted surfaces 311 and the bonding surfaces 320 on the corresponding sides is an acute angle. Specifically, the raising surface 311 is connected to the bonding surface 320 on the corresponding side, the middle of the resisting end surface 310 is a vertical plane 312, the raising surfaces 311 are on two sides, and the vertical plane 312 is perpendicular to the bonding surface 320. Thus, when the resisting end surface 310 abuts against the pressing side wall 111, the raising surface 311 contacts with the pressing side wall 111 in a line, the raising surface 311 forms an included angle with the pressing side wall 111, the included angle is an acute angle, when the raising surface 311 is tightly contacted with the pressing side wall 111 due to a larger acting force, the raising surface 311 slightly deforms, so that the raising surface 311 contacts with the pressing side wall 111, in addition, when the clamping tongue 300 is slightly deformed due to the downward rotation trend caused by the acting force of the pressing side wall 111, the acute angle formed by the raising surface 311 and the pressing side wall 111 can compensate the angle change caused by deformation to a certain extent.

In some embodiments, the angle formed by the raised surface 311 and the corresponding contact surface 320 is greater than 81 ° and less than 89 °, such as 5 ° in the embodiment of fig. 4, so as to avoid too small an angle, resulting in too sharp corners and greater impact than deformation and compensation, resulting in line contact and easy damage.

Of course, in some embodiments, the connection between the raised surface 311 and the corresponding bonding surface 320 may be in a circular arc transition, so as to avoid sharp corners and easy damage caused by stress.

Of course, in some other embodiments, the resisting end surface 310 may be a pure plane, when the resisting end surface 310 is a pure plane, the resisting end surface 310 contacts the pressing sidewall 111, but when the latch 300 is stressed to generate slight deformation and rotation, the contact between the resisting end surface 310 and the pressing sidewall 111 becomes a line contact, and the resisting end surface 310 contacts an upper end corner of the pressing sidewall 111, so that the corner is locally stressed, which is detrimental to structural stability and is easy to damage.

Referring to fig. 3 and 4, in a further embodiment of the present utility model, two sides of the latch 300 are provided with transition surfaces 330, wherein when the engaging surface 320 on one side is attached to the bottom wall of the slot 110, the bottom of the transition surface 330 on the corresponding side is located in the slot 110 and extends out of the slot 110 obliquely upwards in a direction away from the resisting end surface 310. It will be appreciated that the hinge point of the tongue 300 and the clip track box 200 is higher than the track 100, and that the transition surface 330 extends toward and gradually closes the hinge point of the tongue 300 and the clip track box 200. When the latch 300 moves along the direction opposite to the abutment end surface 310 along with the rail clamping box 200, the transition surface 330 contacts with the abutment side wall 111 in the advancing direction, and the latch 300 can be automatically lifted up by the action of the transition surface 330 to separate from the latch groove 110 until the eccentric end of the latch 300 is re-embedded into the latch groove 110 under the action of gravity after entering the next latch groove 110; therefore, after each pushing, the operation of the clamping tongue 300 is not needed to be separated from the current clamping groove 110, and the clamping tongue 300 can be automatically separated from the current clamping groove 110 and falls into the next clamping groove 110, so that automatic operation is realized, manual operation is reduced, and efficiency is improved.

Referring to fig. 5, in some embodiments of the present utility model, a track 100 includes a track body 101 and a track plate 102 fixed on an upper surface of the track body 101, a slot hole is formed in the track plate 102, and a slot 110 is defined by the slot hole and the upper surface of the track body 101, so that a groove is not required to be formed in the track body 101, and only the track plate 102 is required to be connected to the track body 101 after a hole is formed, without affecting the structural strength of the track body 101.

Referring to fig. 2, in some embodiments of the present utility model, a clip rail case 200 includes a case 210 and a limiting plate 220, the limiting plate 220 being connected with the case 210; the bottom of the limiting plate 220 extends below the wing plate 103 at the upper end of the rail 100, so that the limit of the rail clamping box 200 and the rail 100 in the vertical direction is realized. Specifically, the limiting plates 220 are L-shaped plates and are arranged in groups, the number of groups corresponds to the number of the rails 100, two limiting plates 220 in the same group and the box 210 define a rail groove 201 adapted to the outline of the upper end of the rail 100, so that sliding guiding and limiting are achieved, as in the embodiment shown in fig. 1, two rails 100 are arranged, two rail grooves 201 are correspondingly arranged, two groups of limiting plates 220 are correspondingly arranged, and two limiting plates 220 in the same group are symmetrically arranged. Specifically, the limiting plate 220 includes a vertical plate and a transverse plate connected to the bottom of the vertical plate, the transverse plate extends below the wing plate 103 at the upper end of the track 100, and the transverse plates of the two limiting plates 220 in the same group extend in opposite directions, so that the wing plate part at the upper end of the track 100 is wrapped up, and limiting guiding is realized. It will be appreciated that the two limiting plates 220 of the same set are spaced apart to form a gap at the bottom through which the web of the track 100 passes.

In a further embodiment of the present utility model, the vertical plates of the limiting plate 220 and the case 210 are provided with corresponding holes to be connected and fixed by fasteners, and the fasteners may be detachable fasteners such as screws or bolts, so that the limiting plate 220 is detachable, and the rail clamping case 200 can be detached at any time when the rail clamping case 200 is detached.

Of course, in other embodiments of the present utility model, the connection between the limiting plate 220 and the case 210 may be non-detachable, such as welded or riveted, so that the clip rail case 200 can be detached from the end of the rail 100 only.

Referring to fig. 2, in a further embodiment of the present utility model, the case 210 is provided with a positioning block 230, the positioning block 230 is used for positioning and abutting against a corner of the limiting plate 220, and when the limiting plate 220 is installed, the corner of the limiting plate 220 is only required to abut against the positioning block 230, so that the alignment of hole sites can be realized, and the fastener can be conveniently installed, thereby improving the installation accuracy and simplifying the installation difficulty.

In some embodiments of the present utility model, the latch 300 is symmetrically disposed along a symmetry plane, and the rotation axis of the latch 300 is located in the symmetry plane, that is, the tilting surface 311, the fitting surface 320, and the transition surface 330 are symmetrically disposed along the symmetry plane on two sides of the latch 300, so as to ensure that the structures on two sides of the latch 300 are consistent, and the cooperation of the latch 300 is consistent when the pushing direction is switched.

The telescopic driving mechanism 500 may be an oil cylinder, and may ensure that sufficient acting force is provided.

The working principle of the walking system is as follows:
