Description

Technical Field

[0001] The utility model belongs to the technical field of semitrailer fences, and in particular relates to a semitrailer fence which is convenient for inspection and maintenance. Background Art

[0002] Fences are widely used in our production and life. There are garden fences, highway fences, municipal fences, etc. Private villa and courtyard fences are popular in many cities. They are mostly made of wooden panels and consist of three parts: fence boards, horizontal strip boards, and fence posts. They can also be used in conjunction with fences on semi-trailers. Fences are used to limit the goods transported on the semi-trailers to ensure that the goods will not fall off the semi-trailers.

[0003] The semi-trailer fences currently available on the market have the following problems in actual use:

[0004] 1. When the traditional semi-trailer fence is actually used, it needs to be regularly inspected and maintained. In order to ensure the normal use of the fence, the traditional semi-trailer fence is directly fixed on the vehicle body. At this time, when inspecting and maintaining the fence, work can only be done on the vehicle, which is troublesome during inspection and maintenance;

[0005] 2. Most semi-trailer fences may be hit during use, causing the bars on the fences to bend. Most semi-trailer fences have bars that are directly welded and fixed. At this time, when replacing the bars, the entire fence needs to be replaced, which is very costly. Utility Model Content

[0006] The utility model aims to provide a semi-trailer fence which is convenient for inspection and maintenance, so as to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a semi-trailer fence that is easy to inspect and maintain, including a column, a first fixed block is welded on the surface of the column, a sleeve is welded on the surface of the first fixed block, a plug rod is sleeved inside the sleeve, a second fixed block is welded at one end of the plug rod, a fence frame is welded on the side of the second fixed block, a bolt is installed at the other end of the plug rod, and one end of the bolt is fitted to one end of the sleeve.

[0028] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of a semi-trailer fence that is convenient for inspection and maintenance in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, the utility model is a semi-trailer fence which is convenient for inspection and maintenance, including a column 1, a first fixing block 2 is welded on the surface of the column 1, a sleeve 3 is welded on the surface of the first fixing block 2, and a plug rod 6 is sleeved inside the sleeve 3. By sleeve-fitting the plug rod 6 inside the sleeve 3, the connection mode of the welding-type fixed state is eliminated, which provides a basis for disassembly during subsequent inspection and maintenance, and is very convenient to use. A second fixing block 5 is welded at one end of the plug rod 6, and a fence frame 4 is welded on the side of the second fixing block 5. A bolt 7 is installed at the other end of the plug rod 6, and one end of the bolt 7 is fitted to one end of the sleeve 3. By installing the bolt 7, when the semi-trailer fence needs to be inspected and maintained, the bolt 7 can be directly removed, and the fixation of the fence frame 4 can be cancelled at this time, and then the fence frame 4 can be directly moved upward until the plug rod 6 is separated from the inside of the sleeve 3, and then the fence frame 4 can be taken out, which is more convenient for inspection and maintenance.

[0030] A clamping block 8 is welded inside the fence frame 4, and a clamping groove 9 is provided on the surface of the clamping block 8. A fixing rod 10 is clamped inside the clamping groove 9. An external thread is provided on the surface of the fixing rod 10, and an internal thread sleeve 12 is sleeved on the surface of the fixing rod 10. One end of the internal thread sleeve 12 is fixedly connected to an extrusion ring 13. By providing the clamping groove 9, the fixing rod 10 is embedded in the clamping groove 9, which can provide a single disassembly effect for the fixing rod 10. When replacement is needed, it can also be replaced separately, which reduces the cost during use.

[0031] The clamping blocks 8 are symmetrically distributed, and a turntable 11 is welded to the other end of the internal threaded sleeve 12. The turntable 11 is symmetrically distributed. By installing the turntable 11, when the internal threaded sleeve 12 needs to be rotated, the turntable 11 can be used as a force point to directly drive the internal threaded sleeve 12 to rotate, which is very convenient to use.

[0032] The surface of the fence frame 4 is fixedly connected to a fixing seat 14, which is symmetrically distributed. A fixing frame 15 is welded to the other end of the fixing seat 14. By installing the fixing frame 15, when moving or taking the fence frame 4, the fixing frame 15 can be directly grasped, and the fixing frame 15 is used as a force point to move or take the fence frame 4, which is very convenient to use.

[0033] The surface of the fixing frame 15 is sleeved with an anti-slip sleeve 17, and a retaining ring 16 is welded on the surface of the fixing frame 15. Both ends of the anti-slip sleeve 17 are fitted on the retaining ring 16. The surface of the anti-slip sleeve 17 is fixedly connected to a soft ball head 18. By installing the anti-slip sleeve 17, when the fixing frame 15 is held, the friction between the fixing frame 15 and the palm can be increased, and the fixing frame 15 is more stable when held, and has greater stability when used.

[0034] The fixing rods 10 are distributed in an equidistant manner, and upright posts 1 are arranged outside the fixing rods 10 . A transverse plate 19 is welded to the side of the upright posts 1 . By installing the transverse plate 19 , the strength between the upright posts 1 can be enhanced, thereby improving the stability of the semi-trailer fence during use.

[0035] The working principle of the semi-trailer fence that is easy to inspect and maintain: when using the semi-trailer fence that is easy to inspect and maintain, the fence frame 4 should be installed on the column 1 first. During installation, the insertion rod 6 is directly embedded in the sleeve 3, and then the bolt 7 is installed at one end of the insertion rod 6 through the sleeve 3 until one end of the bolt 7 fits with one end of the sleeve 3. Then, the fixing rod 10 is installed in the fence frame 4. When installing the fixing rod 10, the fixing rod 10 is directly embedded in the slot 9 on the block 8. Then, the turntable 11 is rotated to drive the internal threaded sleeve 12, and then the extrusion ring 13 is driven to extrude the block 8. At this time, the fixing rod 10 can be fixed in the slot 9. When the semi-trailer fence needs to be inspected and maintained, When protecting, the bolts 7 can be directly removed, and the fixation of the fence frame 4 can be cancelled. Then the fence frame 4 can be directly moved upward until the insertion rod 6 is separated from the inside of the sleeve 3, and then the fence frame 4 can be taken out. At this time, it is more convenient for inspection and maintenance. When the fixing rod 10 is bent by a collision, the internal threaded sleeve 12 can be rotated until the extrusion ring 13 is separated from the surface of the block 8, and then the fixing rod 10 can be directly taken out, and the intact fixing rod 10 can be embedded in the slot 9. At the same time, the internal threaded ring is rotated to drive the extrusion ring 13 to move, thereby increasing the friction between the extrusion ring 13 and the block 8, and then the fixing rod 10 is fixed. A single fixing rod 10 can be replaced to reduce costs during use.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
