DETAILED DESCRIPTION OF THE INVENITON

[0038] The object, the technical solution and the advantages of the present application will appear more clearly on reading the following detailed description with reference to Figures 1 to 7 and the following embodiments.

[0039] A fence is disclosed in the embodiments of the present application, with reference to Figures 1 and 2, which comprises a post component 1, crossbars 2, screws 3 and shelter strips 4. The post component 1 comprises fasteners 11 and post bodies 12.

[0040] The post body 12 is fixed on a surrounding wall or on the ground, and the figures of the present embodiment specifically show the fixing on a surrounding wall. The fastening piece 11 is relatively fixed on the post body 12 using the screws 3, the crossbar 2 is relatively fixed on the fastener 11 by means of the screws 3, that is, the crossbar 2 is indirectly fixed to the post body 12 via the fastener 11, thereby reducing the difficulty of installing the crossbar 2 and the post body 11. Two ends of the crossbar 2 abut against the fasteners 11 of two adjacent post bodies 12 and are subject to the axial limitation of the two fasteners 11, thereby increasing the stability of the crossbar 2 on the fasteners 11.

[0041] The crossbar 2 is a rectangular hollow tube, each crossbar 2 is integrally connected, at the central position of the interior, to a fixing tube 21, the fastening piece 11 is provided with an installation hole 1114, and the screws 3 simultaneously pass through the installation hole 1114 of the fastening piece 11 and the fixing tube 21 to fix the crossbar 2 relative to the fastening piece 11. Thus, the crossbar 2 of the present embodiment can achieve a reduction in weight and production costs while ensuring a stable connection with the fastening piece 11.

[0042] Referring to Figures 1 and 3, the shelter strip 4 is installed on the crossbar 2 close to both ends of the post body 12 and closes two ends of a portion of the attachment piece 11 connected to the crossbar 2, thereby reducing the penetration of rain, dust and other substances into the crossbar 2 through the junction between the crossbar 2 and the attachment piece 11, thereby increasing the stability of the crossbar 2 on the installation portion 1112.

[0043] There are two types of shelter strip 4, one is that the shelter strip 4 is close to one end of the post body 12 connected to the surrounding wall, and the other is that the shelter strip 4 is close to one end of the post body 12 away from the surrounding wall. The shelter strips 4 of both types have the same structure similar to that of the crossbar 2. The present embodiment will be explained by taking the shelter strip 4 close to one end of the post body 12 away from the surrounding wall as an example, and the installation method of the other shelter strip 4 to the crossbar 2 can be deduced easily and therefore will not be repeated here.

[0044] Each shelter strip 4 comprises an abutting portion 41 and a covering portion 42. The abutting portion 41 abuts against a side of the crossbar 2 remote from the surrounding wall. The abutting portion 41 is provided, on a side remote from the side abutting against the crossbar 2, with a third screw groove 411, and the cap of the screw 3 is engaged at the bottom of the third screw groove 411, so that the abutting portion 41 is pressed onto the crossbar 2 and the cap of the screw 3 penetrates into the abutting portion 41, thereby reducing the influence on the covering portion 42. The covering portion 42 is arranged on one side of the abutting portion 41 and closes the opening of the third screw groove 411. The arrangement of the cover portion 42 provides protection to the screws 3 in the abutting portion 41, and reduces corrosion of the screws 3 by rain, dust and other substances. An engagement strip 412 is provided on an outer side of each of two side walls of the third screw groove 411 and integrally connected to the abutting portion 41, and the cover portion 42 is provided with the engagement grooves 421 to allow the two engagement strips 412 to be engaged therein. The engagement strips 412 are engaged in the engagement grooves 421, which increases the stability of the connection between the cover portion 42 and the abutting portion 4L

[0045] Referring to Figures 1 and 2, the post body 12 comprises a post trunk 121, a base 122, an end cover 123 and a second sealing strip 124. The base 122 is fixed to the surrounding wall using the fixing parts such as bolts. The post trunk 121 is a hollow tube, which is inserted into the base 122, and one end of the post trunk 121 is fixed on the base 122 using the fixing parts such as bolts. The end cover 123 is arranged by covering one end of the post trunk 121 away from the base 122 to reduce the penetration of rain into the post trunk 121 which has influences on the post trunk 121 and the base 122.

[0046] Referring to [Fig.4], a second slide 1211 for allowing the fastener 11 to slide and be engaged therein is provided on any side of the outer wall of the post trunk 121, the sliding and engagement provide a good guiding effect and allow the fastener 11 to be guided and installed on the post trunk 121. The number of second slides 1211 on each side of the outer wall of the post trunk 121 is determined according to the width and thickness of each side of the post trunk 121. In the present embodiment, the post trunk 121 is provided on one side with two second slides 1211, and the two second slides 1211 share the same groove wall. The post trunk 121 is provided on an adjacent side with a second slide 1211.

[0047] The bottom of the second slide 1211 is provided with a convex bar 1212 integrally connected to the pole trunk 121. The convex bar 1212 is provided with a positioning hole 1213 to allow the screws 3 to pass through it, and the positioning hole 1213 can also be directly formed by passing the screw 3 through the convex bar 1212. The attachment member 11 is provided, on a side close to the bottom of the second slide 1211, with a third slide 11IB. The attachment member 11 is engaged on the convex bar 1212 through the third slide 11IB. The attachment member 11 is provided, on a side opposite from the third slide 11 IB, of a fixing hole 1113 to allow the screws 3 to pass through it. The third slide 11 IB reduces the thickness of the attachment piece 11, and the convex bar 1212 increases the thickness of the pole trunk 121, when the screw 3 simultaneously passes through the fixing hole 1113 and the positioning hole 1213, and the body of the screw 3 remains more on the convex bar 1212, which increases the stability of the connection between the attachment piece 11 and the pole trunk 121.

[0048] Referring to Figures 5 to 6, the fastener 11 comprises a base bar 111 and a first sealing strip 112. The base bar 111 is an "L" shaped strip, which comprises a fixing portion 1111 and an installation portion 1112 connected to one side of the fixing portion 1111. Referring to [Fig.4], the fixing portion 1111 of the base bar 111 slides and is engaged in the second slide 1211, and the third slide 111B is provided on one side of the fixing portion 1111 close to the bottom of the second slide 1211.

[0049] The fixing portion 1111 of the base bar 111 is provided, on a side remote from the bottom of the second slide 1211, with a first screw groove 1116 to allow the screw cap 3 to be engaged therein. The screw cap 3 is engaged in the first screw groove 1116, so that the fixing portion 1111 is pressed onto the post trunk 121, and the screw cap 3 is penetrated into the fixing portion 1111, thereby reducing the influence on the sliding of the crossbar 2 in the first slide 1115.

[0050] The bottom of the first screw groove 1116 is provided at the central position and along the axial direction of the fixing portion 1111, with a first guide groove 1117 to allow the tip of the screw 3 to be engaged therein. The first guide groove 1117 limits the tip of the screw 3, which helps in the accurate positioning of the screw 3 on the first screw groove 1116 and facilitates the passage of the screw 3 through the first screw groove 1116. The fixing hole 1113 can also be formed directly by passing the screw 3 through the first guide groove 1117. The screw 3 simultaneously passes through the fixing hole 1113 and the positioning hole 1213 to relatively fix the fixing portion 1111 on the post trunk 121.

[0051] The fixing portion 1111 is provided with a first sealing groove 1118 close to the opening of the first screw groove 1116, and the first sealing groove 1118 is in communication with the first screw groove 1116. The first sealing strip 112 is a "T" shaped strip and is engaged in the first sealing groove 1118 to completely close the opening of the first screw groove 1116, which helps to close the screws 3 in the first screw groove 1116, and reduces corrosion of the screw cap 3 by rain, dust and other substances, moreover, the first sealing strip 112 fills a part of the first screw groove 1116, which increases the overall strength of the fixing portion 1111 and increases the stability of the connection between the fixing portion 1111 and the installation portion 1112.

[0052] Referring to Figures 2 and 6, the installation portion 1112 is provided, on a side close to the crossbar 2, with a first slide 1115. The crossbar 2 slides and is engaged in the first slide 1115, which helps the crossbar 2 to be guided and installed in the installation portion 1112 of the base bar 111, and the crossbar 2 is also subjected to the axial limitation of the installation portion 1112, which increases the stability of the crossbar 2 on the installation portion 1112.

[0053] The installation portion 1112 is provided, on one side facing the first slide 1115, with a second screw groove 1119 to allow the screw cap 3 to be engaged therein. The screw cap 3 is engaged in the second screw groove 1119, so that the installation portion 1112 is pressed onto one end of the crossbar 2, and the screw cap 3 is penetrated into the installation portion 1112, thereby reducing the influence of other screws 3 on the installation portion 1112 of the base bar 111 adjacent to the same post trunk 121.

[0054] The bottom of the second screw groove 1119 is provided at the central position and along the axial direction of the installation portion 1112, with a second guide groove 111A to allow the tip of the screw 3 to be engaged therein. The second guide groove 111A limits the tip of the screw 3, which helps in the accurate positioning of the screw 3 on the second screw groove 1119 and facilitates the passage of the screw 3 through the second screw groove 1119. The installation hole 1114 can also be formed directly by passing the screw 3 through the second guide groove 111A. The screw 3 simultaneously passes through the installation hole 1114 and the fixing tube 21 to relatively fix the crossbar 2 on the installation portion 1112.

[0055] Referring to [Fig.7], the post trunk 121 is further provided with a second sealing groove 1214 in communication with the second slide 1211. The type of the second sealing groove 1214 is selected according to the number of the second slide 1211. In the present embodiment, there are two types of second sealing grooves 1214, one type of second sealing groove 1214 is in communication with only one second slide 1211 and the other type of second sealing groove 1214 is in communication with two second slides 1211 sharing the same groove wall. The number of the second sealing strip 124 and the number of the second sealing groove 1214 are in one-to-one correspondence, and there are also two types of second strip sealing strip 124 in the present embodiment. When the fixing portion 1111 of the base bar 111 is not connected to the post trunk 121, the second sealing strip 124 is engaged in the second sealing groove 1214 to close the opening of the second slider 1211, thereby reducing corrosion of the second slider 1211 by rain, dust and other substances and improving the overall aesthetics of the post trunk 121.

[0056] The principle of implementation of the embodiments of the present application is as follows:

[0057] The post trunk 121 is fixed to the surrounding wall, the fixing portion 1111 of the base bar 111 is relatively fixed on the post trunk 121 by means of the screws 3, and one end of the cross bar 2 slides and is engaged on the installation portion 1112 of the base bar 111. The installation portions 1112 of the two base bars 111 on the two adjacent post trunks 121 are abutted against the two ends of the cross bar 2, so that the cross bar 2 is subjected to the axial limitation of the two installation portions 1112, which increases the stability of the cross bar 2 on the installation portion 1112.The crossbar 2 is relatively fixed on the installation portion 1112 of the base bar 111 by means of the screws 3, because the fixing portion 1111 is integrally connected to the installation portion 1112, the crossbar 2 is relatively indirectly fixed to the post trunk 12 via the base bar 111 with low difficulty of installation.

[0058] The specific embodiments are only for illustrative purposes to describe the present application, rather than to limit the present application, and based on the present description, one skilled in the art can make modifications to the embodiments without creative work, without departing from the scope of the present application.
