When the height of the stand column body needs to be adjusted, only the locking pin needs to be unscrewed, so that the stand column body, the locking pin and the friction plate can slide up and down relative to the accommodating groove (namely, the positioning piece), the height adjustment of the stand column body can be realized, and the locking pin can be screwed down again after the adjustment. In conclusion, the locking piece is simple in structure, convenient to install and convenient to adjust the height of the upright post body.

Preferably, when the friction plate abuts against the inner side surface of the pillar body, the friction plate abuts against the inner side surface of the accommodating groove. The advantages are that: when the friction plate butt in the inboard face of stand body, if the friction plate does not butt in the medial surface of holding tank, then the friction plate with locking effect between the holding tank (promptly setting element) leans on entirely the fitting pin with static frictional force between the holding tank medial surface, at this moment, the fitting pin with area of contact between the holding tank medial surface is less, rotates the fitting pin during easy right the holding tank medial surface causes wearing and tearing. However, when the friction plate abuts against the inner side surface of the column body, if the friction plate abuts against the inner side surface of the accommodating groove, the locking action between the friction plate and the accommodating groove (i.e., the positioning element) is against the static friction force between the locking pin and the inner side surface of the accommodating groove and between the friction plate and the inner side surface of the accommodating groove, which is equivalent to increase the contact area between the locking pin and the inner side surface of the accommodating groove, and is beneficial to reducing the abrasion caused by the rotation of the locking pin to the inner side surface of the accommodating groove.

When the fence system is actually installed on site, the fence net plate 5 and the stand column body 4 can be installed and fixed fast through the connecting piece 6, the installation is convenient, and the installation efficiency is high. In the installation, if the high not enough or overlength condition of stand body 4 appears, when needing the height of adjustment stand body 4, only need remove retaining member 3's locking effect earlier, slide stand body 4 from top to bottom again to increase and decrease stand body 4's height, the function is more various, and the commonality is stronger. Particularly, after the fence net plate 5 is fixed, the height of the fence net plate 5 can be adjusted by adjusting the height of the upright post body 4; compare in traditional structure, the height of stand body 4 and rail otter board 5 can be adjusted to the rail system of this kind of structure, and it is more convenient to install, and the installation effectiveness is higher, and the commonality is stronger.

Referring to fig. 2, 3 and 4, in some embodiments of the present application, an upper insertion hole 51 is formed at an upper end of the fence panel 5, and a lower insertion hole 52 is formed at a lower end of the fence panel 5; the connecting piece 6 comprises an upper fixing ring 61, a lower fixing ring 62 and at least two fasteners; the upper fixing ring 61 and the lower fixing ring 62 can be connected to the column body 4 in a vertically sliding manner, the outer annular surface of the upper fixing ring 61 is provided with an upper insert block 611, the outer annular surface of the lower fixing ring 62 is provided with a lower insert block 621, and the upper insert block 611 and the lower insert block 621 are respectively inserted into the upper insertion hole 51 and the lower insertion hole 52; at least two fasteners are respectively disposed on the upper fixing ring 61 and the lower fixing ring 62, and the fasteners are used for limiting the upper fixing ring 61 and the lower fixing ring 62 to slide up and down. The upper fixing ring 61 and the lower fixing ring 62 can be fixed on the column body 4 by fasteners, and the fence net plate 5 can be installed and fixed by respectively inserting the upper insertion block 611 and the lower insertion block 621 into the upper insertion hole 51 and the lower insertion hole 52; in addition, after the locking action of the fastening piece on the upper fixing ring 61 and the lower fixing ring 62 is released, the upper fixing ring 61 and the lower fixing ring 62 can be adjusted to slide up and down along the upright post body 4, so that the interval between the upper fixing ring 61 and the lower fixing ring 62 (namely between the upper insert block 611 and the lower insert block 621) can be adjusted to adapt to the fence net plates 5 with different heights; further, when the upper fixing ring 61 and the lower fixing ring 62 are adjusted to slide up and down at the same time, the installation height of the fence plate 5 to the column body 4 can be adjusted.

Referring to fig. 2, 3 and 4, in some embodiments of the present application, the outer annular surfaces of the upper fixing ring 61 and the lower fixing ring 62 are provided with mounting holes 612 therethrough; the fastening member is a locking bolt (the locking bolt is not shown in the drawings), the locking bolt is in threaded connection with the mounting hole 612, and the threaded end of the locking bolt abuts against the outer side face of the stand column body 4. When the locking bolt is tightened, the threaded end of the locking bolt abuts against the outer side surface of the stand column body 4, so that the upper fixing ring 61 and the lower fixing ring 62 can be limited to slide up and down; when the lock bolt is loosened, the threaded end of the lock bolt is disengaged from the outer side surface of the column body 4, so that the locking action on the upper fixing ring 61 and the lower fixing ring 62 can be released, so that the heights of the upper fixing ring 61 and the lower fixing ring 62 can be slidably adjusted up and down.

Referring to fig. 7 and 8, in some embodiments of the present application, at least one outer side surface of the positioning element 2 is provided with an accommodating groove 210, and the lower end of the pillar body 4 is provided with a yielding hole 41 corresponding to the outer side surface of the accommodating groove 210; the locking member 3 includes a friction plate 31 and a locking pin 32; the friction plate 31 is movably disposed in the receiving groove 210 up and down, and a threaded hole 310 is formed through the friction plate 31; the locking pin 32 is screwed into the threaded hole 310, one end of the locking pin 32 is aligned with the relief hole 41, and the other end of the locking pin 32 abuts against the inner side surface of the receiving groove 210, so as to force the friction plate 31 to abut against the inner side surface of the pillar body 4. As shown in fig. 14, the locking pin 32 can be screwed into the threaded hole 310 through the relief hole 41 until one end of the locking pin 32 deviating from the relief hole 41 abuts against the inner side surface of the receiving groove 210, and the friction plate 31 can be forced to move along the horizontal direction to the outside of the receiving groove 210 by continuing to rotate the locking pin 32, so that the friction plate 31 can abut against the inner side surface of the column body 4; at this time, the static friction force between the friction plate 31 and the column body 4 can limit the relative motion between the friction plate 31 and the column body 4, and the static friction force between the locking pin 32 and the inner side surface of the receiving groove 210 can limit the relative motion between the locking pin 32 (i.e. the friction plate 31) and the receiving groove 210 (i.e. the positioning element 2), so that the locking between the column body 4 and the positioning element 2 can be realized to maintain the height of the column body 4 unchanged. When the height of the column body 4 needs to be adjusted, the locking pin 32 only needs to be unscrewed, so that the column body 4, the locking pin 32 and the friction plate 31 can slide up and down relative to the accommodating groove 210 (i.e., the positioning member 2), the height of the column body 4 can be adjusted, and the locking pin 32 is screwed again after the adjustment. In conclusion, the locking member 3 has a simple structure, is convenient to install, and is convenient for adjusting the height of the upright post body 4. It should be noted that, in the present application, the number of the yielding holes 41 arranged on the same outer side surface of the column body 4 is not limited, but the number of the yielding holes 41 should be equal to the number of the threaded holes 310; according to the principle of two points and one line, the number of the abdicating holes 41 on the same outer side surface is preferably two, that is, the number of the threaded holes 310 on the same friction plate 31 is preferably two, which is beneficial to ensuring that the upright post body 4 is less prone to shaking after being locked, and the stability is higher.

Referring to fig. 14, in some embodiments of the present application, when the friction plate 31 abuts against the inner side surface of the pillar body 4, the friction plate 31 abuts against the inner side surface of the receiving groove 210. When the friction plate 31 abuts against the inner side surface of the column body 4, if the friction plate 31 does not abut against the inner side surface of the receiving groove 210, the locking action between the friction plate 31 and the receiving groove 210 (i.e. the positioning element 2) is entirely by the static friction force between the locking pin 32 and the inner side surface of the receiving groove 210, and at this time, the contact area between the locking pin 32 and the inner side surface of the receiving groove 210 is small, and the inner side surface of the receiving groove 210 is easily worn when the locking pin 32 is rotated. However, when the friction plate 31 abuts against the inner side surface of the column body 4, if the friction plate 31 abuts against the inner side surface of the receiving groove 210, the locking action between the friction plate 31 and the receiving groove 210 (i.e. the positioning element 2) is against the static friction force between the locking pin 32 and the inner side surface of the receiving groove 210 and between the friction plate 31 and the inner side surface of the receiving groove 210, and at this time, the contact area between the locking pin 32 and the inner side surface of the receiving groove 210 is increased, which is beneficial to reducing the wear caused to the inner side surface of the receiving groove 210 when the locking pin 32 is rotated.

Referring to fig. 8 and 14, in some embodiments of the present disclosure, the two opposite outer lateral surfaces of the positioning element 2 are respectively provided with a receiving groove 210, and a friction plate 31 is movably connected to each receiving groove 210 up and down. The quantity of holding tank 210 (locking piece 3 promptly) is more, and the locking effect between stand body 4 and the setting element 2 is better, and the cost also can be higher more simultaneously, synthesizes comparatively, and two holding tanks 210 through this kind of subtend setting can two locking pieces 3 of subtend installation, can guarantee that holistic atress is more even, reliable, can follow reduce cost's angle, improves locking effect of locking piece 3 to the at utmost.

Referring to fig. 9 and 10, in some embodiments of the present application, the positioning member 2 includes a connection plate 21 and two positioning plates 22 having an "Contraband" shape; the two positioning plates 22 are oppositely and alternately fixed on the support member 1, and the outer side surfaces of the two positioning plates 22 are connected to the inner side surface of the upright post body 4 in a vertically sliding manner; the connecting plate 21 is fixed between the two positioning plates 22, and two accommodating grooves 210 are defined between the connecting plate 21 and the two positioning plates 22. Referring to fig. 11 and 12, the cross section of the friction plate 31 includes a first straight section 311, and the first straight section 311 abuts against the inner side surface of the pillar body 4; both ends of the first straight section 311 are bent towards the direction of the connecting plate 21 to form a second straight section 312, the second straight section 312 is parallel to the first straight section 311, and the second straight section 312 abuts against the inner side surface of the accommodating groove 210; the threaded hole 310 is formed in the first straight section 311. The positioning member 2 and the friction plate 31 having such a structure are easy to process, and can sufficiently reduce the material cost while ensuring sufficient strength. In addition, when the locking pin 32 is rotated until the locking pin 32 abuts against the inner side surface (i.e. the connection plate 21) of the receiving groove 210, the friction plate 31 can be forced to slide horizontally towards the outside of the receiving groove 210 (i.e. away from the direction of the connection plate 21) by continuing to rotate the locking pin 32, so that the first straight section 311 abuts against the inner side surface of the pillar body 4, and the second straight section 312 abuts against the inner side surface of the receiving groove 210. In other words, the tighter the locking pin 32 is screwed, the tighter the second straight section 312 and the inner side surface of the accommodating groove 210 are abutted to, and the easier the deformation between the first straight section 311 and the two second straight sections 312 occurs, so that the abutment between the first straight section 311 and the inner side surface of the column body 4 is tighter, and the locking effect can be fully improved. In addition, because the lateral surfaces of two positioning plates 22 are connected to the inner lateral surface of the column body 4 in a vertical sliding manner, when the second straight section 312 abuts against the inner lateral surface of the accommodating groove 210, the inner lateral surface of the column body 4 can also limit the positioning plate 22 to prevent the positioning plate 22 from being extruded and deformed by the second straight section 312, even if the positioning plate 22 is slightly deformed due to the extrusion of the second straight section 312, the static friction force between the lateral surface of the positioning plate 22 and the inner lateral surface of the column body 4 can also be increased, and thus the locking effect can be improved. In addition, the two locking pins 32 disposed opposite to each other can cancel the acting force on the connecting plate 21, so that the deformation of the connecting plate 21 can be prevented. It should be noted that. As shown in fig. 14, since the cross section of the conventional column body 4 is generally square, the two receiving grooves 210 are respectively adapted to correspond to two outer side surfaces of the column body 4 with larger width, that is, the relief holes 41 are formed on the two outer side surfaces of the column body 4 with larger width (that is, on the left and right side surfaces of the column body 4 in fig. 14).

Referring to fig. 11, 12 and 14, in some embodiments of the present application, one end of the second straight section 312, which is offset from the first straight section 311, is bent in a direction of the connection plate 21 to form a third straight section 313. On one hand, the third straight section 313 can increase the strength of the second straight section 312, which is beneficial to prevent the second straight section 312 from deforming. On the other hand, if the third straight section 313 is not provided, the friction plate 31 is easy to tilt in the receiving groove 210, that is, the threaded hole 310 is easy to tilt, so that the difficulty of aligning the relief hole 41 with the threaded hole 310 is increased, that is, the difficulty of installing the locking pin 32 is increased; the third straight section 313 occupies a part of the space of the receiving groove 210, so that the friction plate 31 can always stand in the receiving groove 210, and the offset hole 41 is aligned with the threaded hole 310, thereby facilitating the installation of the locking pin 32.

Referring to fig. 11, 12 and 14, in some embodiments of the present application, the threaded hole 310 is formed by extending a first straight section 311 in a direction of the connection plate 21. The threaded hole 310 with the structure can fully increase the depth of the threaded connection between the locking pin 32 and the threaded hole 310, thereby being beneficial to improving the stability of the threaded connection between the locking pin 32 and the threaded hole 310; in addition, the strength of the periphery of the screw hole 310 can be improved by the screw hole 310 having such a configuration.

Referring to fig. 8 and 9, in some embodiments of the present disclosure, a welding hole 221 and a first positioning hole 222 are formed through the positioning plate 22 at a position corresponding to the connecting plate 21, and a second positioning hole 211 is formed through the connecting plate 21 at a position corresponding to the first positioning hole 222. The first positioning hole 222 and the second positioning hole 211 are matched with each other, so that the connection plate 21 and the two positioning plates 22 are positioned conveniently, and the connection plate 21 is welded and fixed on the positioning plates 22 through the welding holes 221. In addition, in order to improve the welding strength and accuracy, the welding holes 221 and the first positioning holes 222 are preferably arranged in a staggered manner.

Referring to fig. 14, in some embodiments of the present application, the outer diameter of the locking pin 32 is equal to the inner diameter of the relief hole 41. When the outer diameter of the locking pin 32 is equal to the inner diameter of the abdicating hole 41, the relative motion between the friction plate 31 and the column body 4 can be limited between the locking pin 32 and the abdicating hole 41, and at this time, even if the static friction force between the first straight section 311 and the inner side surface of the column body 4 is not large enough, the relative motion between the friction plate 31 and the column body 4 is not generated, and the stability is higher. In addition, when the height of the upright post body 4 is adjusted, the limit fit between the locking pin 32 and the abdicating hole 41 also limits the relative movement between the friction plate 31 and the upright post body 4, so that the synchronism of the movement of the upright post body 4, the locking pin 32 and the friction plate 31 in the adjusting process can be ensured; that is, when the height of the pillar body 4 is adjusted, the pillar body 4 is held and slid up and down to a proper position, and then the locking pin 32 is screwed down; otherwise, if the size of the yielding hole 41 is larger, the locking pin 32 is easy to rock in the yielding hole 41, and the yielding hole 41 is easy to incline the locking pin 32 in the process of sliding the pillar body 4 up and down, so that the difficulty of locking again can be increased. Preferably, the portion of the locking pin 32 that is combined with the offset hole 41 is a circular structure (i.e., no thread is provided, not shown in the drawings), so as to increase the contact area between the locking pin 32 and the offset hole 41 (i.e., the pillar body 4).

Referring to fig. 13 and 14, in some embodiments of the present disclosure, an end surface of the locking pin 32 offset from the receiving groove 210 is flush with a side surface of the column body 4, and the end surface of the locking pin 32 offset from the receiving groove 210 is provided with a rotation groove 321. When the end surface of the locking pin 32 deviating from the accommodating groove 210 is flush with the side surface of the column body 4, the locking pin 32 does not protrude outside the column body 4, so that the locking pin 32 can be hidden; in addition, the locking pin 32 is conveniently rotated by the rotation groove 321.

Referring to fig. 1, 5 and 6, the enclosure system further includes a protective cover 7, and the protective cover 7 covers the base body 100 to protect the base body 100. It should be noted that the protection cover 7 itself and the installation manner thereof are prior art, and detailed description thereof is omitted in this application.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and such changes and modifications are intended to be within the scope of the application as claimed.
