DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, understandable and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] Please refer to Figure 1 The embodiment of the present application provides a carriage tensioning device, which comprises a flexible tensioning member 1, a winding mechanism 2 and a fixing member 3.

[0024] The flexible tensioning member 1 is used to provide a tensioning force to the opposite two side walls 5 of the carriage, and the flexible tensioning member 1 is selected from a steel wire rope, or a lock chain or a chain.

[0025] The winding mechanism 2 comprises a winding shell 201 and a winding shaft 202, and the winding shell 201 and the fixing member 3 are fixedly connected with the opposite two side walls 5 of the carriage, specifically fixed on the upright columns of the side walls 5, and the winding shaft 202 is rotationally connected with the winding shell 201. One end of the flexible tensioning member 1 is connected with the winding shaft 202, and the other end of the flexible tensioning member 1 is detachably connected with the fixing member 3 through a basket bolt 4. The flexible tensioning member 1 can be wound to the inside of the winding shell 201 by rotating the winding shaft 202.

[0026] The fixing member 3 can be a pull ring or an ear plate. The basket bolt 4 is a prior art, which comprises a ring-shaped connecting head 41, a hook-shaped connecting head 42, a basket nut, a left threaded screw rod and a right threaded screw rod. The ring-shaped connecting head 41 is connected with the flexible tensioning member 1, the hook-shaped connecting head 42 is detachably connected with the fixing member 3, the left threaded screw rod and the right threaded screw rod are both threadedly connected with the basket nut, the left threaded screw rod is connected with the ring-shaped connecting head 41, and the right threaded screw rod is connected with the hook-shaped connecting head 42. By rotating the basket nut, the two threaded screw rods move relatively, so that the extension and retraction functions of the basket bolt can be realized. The tension of the flexible tensioning member 1 can be adjusted by rotating the basket bolt 4.

[0027] The materials and strengths of the components such as the flexible tensioning member 1, the winding shell 201, the winding shaft 202 and the basket bolt 4 need to be matched with the tensioning force.

[0028] When the cargo needs to be pulled and the carriage needs to be tensioned, the winding shaft 202 is rotated, or the flexible tensioning member 1 is directly pulled, the flexible tensioning member 1 is unwound from the winding shaft 202, and then the hook-shaped connecting head 42 is connected with the fixing member 3.

[0029] The length of the flexible tensioning member 1 is adapted to the width of the carriage, and when the hook-shaped connector 42 is connected to the fixing member 3, the flexible tensioning member 1 is already substantially tensioned, and then the flower basket bolt 4 is further used to adjust the tension of the flexible tensioning member 1, so as to achieve the required strength and tightness.

[0030] When the carriage does not need to be tensioned, the flexible tensioning member 1 is wound on the winding shaft 202 by reversing the winding shaft 202, so as to facilitate the collection of the flexible tensioning member 1 on the carriage, avoid loss during transportation, and avoid disorderly winding of the flexible tensioning member 1, which affects subsequent quick use.

[0031] In a preferred embodiment, in order to improve the adaptability to carriages of different widths and facilitate the connection of the hook-shaped connector 42 to the fixing member 3, the winding mechanism 2 further comprises a locking plate 203, a plug rod 204, and a fixing seat 205. The locking plate 203 is slidingly installed on the winding shaft 202, and the fixing seat 205 is fixedly installed on the winding housing 201. An insertion hole 206 is formed in the end face of the fixing seat 205 facing the locking plate 203. The plug rod 204 is fixed on the locking plate 203 and is used to be inserted into the insertion hole 206. The locking of the winding shaft 202 is achieved by the cooperation of the plug rod 204 and the insertion hole 206.

[0032] In this embodiment, the number of the insertion holes 206 and the plug rods 204 is eight. The insertion holes 206 are circumferentially distributed on the fixing seat 205, and the plug rods 204 are also circumferentially distributed on the locking plate 203. The plug rods 204 can be uniformly inserted into the corresponding insertion holes 206.

[0033] When winding and unwinding the flexible tensioning member 1, the locking plate 203 needs to be lifted so that the plug rod 204 is lifted above the insertion hole 206, and then the winding shaft 202 can be rotated. After the winding and unwinding of the flexible tensioning member 1 is completed, the locking plate 203 is loosened, and the winding shaft 202 is slightly rotated so that the plug rod 204 is rotated above the insertion hole 206 and then inserted into the insertion hole 206, thereby limiting the rotation of the winding shaft 202.

[0034] The extension function of the flower basket bolt 4 cooperates with the winding mechanism 2 to realize the double adjustment of the tensioning force of the flexible tensioning member 1.

[0035] On the basis of the above-mentioned embodiments, in order to facilitate the rotation of the winding shaft 202, the winding mechanism 2 further comprises a rotating handle 208 fixedly installed on the top end of the winding shaft 202. By holding the rotating handle 208, the winding shaft 202 can be conveniently rotated.

[0036] On the basis of the above embodiment, in order to facilitate the stable insertion of the insertion rod 204 into the insertion hole 206 and avoid the insertion rod 204 from being separated from the insertion hole 206 under vibration, the winding mechanism 2 further comprises a compression spring 207, one end of the compression spring 207 is connected with the rotating handle 208, and the other end of the compression spring 207 is connected with the locking plate 203. The compression spring 207 provides downward pressure to the locking plate 203, so that the insertion rod 204 is stably inserted into the insertion hole 206, and the bumps during vehicle driving will not easily cause the insertion rod 204 to be separated from the insertion hole 206.

[0037] On the basis of the above embodiment, in order to facilitate the lifting of the locking plate 203, the locking plate 203 is fixed with an outer sleeve 209, and the outer sleeve 209 is fixed with a handle 210. The handle 210 is provided with two, when it is needed to rotate the winding shaft 202, the palm can be first pressed against the rotating handle 208, and then the fingers can be hooked around the handle 210, the fingers can exert force to lift the handle 210, and then the outer sleeve 209, the locking plate 203 and the insertion rod 204 are lifted, so that the insertion rod 204 is separated from the insertion hole 206, and then the rotating handle 208 and the handle 210 can be rotated together to drive the winding shaft 202 to rotate.

[0038] On the basis of the above embodiment, in order to avoid the hand from contacting the compression spring 207, the lower end of the rotating handle 208 is fixed with an inner sleeve 213, the inner sleeve 213 is located inside the outer sleeve 209, the inner sleeve 213 is in sliding connection with the outer sleeve 209, the compression spring 207 is located inside the inner sleeve 213, and the outer wall of the inner sleeve 213 is in contact with the inner wall of the outer sleeve 209. The inner sleeve 213 and the outer sleeve 209 can protect the compression spring 207 from being contacted by the hand. The inner sleeve 213 and the outer sleeve 209 are both circular sleeves, and the inner sleeve 213 and the outer sleeve 209 can rotate relative to each other.

[0039] In a preferred embodiment, in order to facilitate the connection of the flexible tensioning element 1 with the winding shaft 202 and facilitate disassembly, the one end of the flexible tensioning element 1 is provided with a shackle 6, and the flexible tensioning element 1 is detachably connected with the winding shaft 202 through the shackle 6.

[0040] On the basis of the above embodiment, in order to facilitate the limiting of the position of the shackle 6 in the axial direction of the winding shaft 202, and thus keep the position where the flexible tensioning element 1 is connected with the winding shaft 202 stable, a limiting plate 211 is fixed on the winding shaft 202 and located inside the winding housing 201. The limiting plate 211 bears the shackle 6 and limits the descent of the shackle 6. The flexible tensioning element 1 can be wound in the winding housing 201 and at a position below the limiting plate 211.

[0041] The shackle is a metal fastener in the prior art, also known as a buckle or a clasp, which is mainly used to connect two or more articles. Specifically, it can be a D-shaped shackle or an arc-shaped shackle.

[0042] In a preferred embodiment, in order to stably rotate the winding shaft 202 and install it on the winding housing 201, bearings 212 are arranged on the upper and lower ends of the winding housing 201, and the winding shaft 202 is rotatably connected with the winding housing 201 through the bearings 212. By arranging the bearings 212, the friction between the winding shaft 202 and the winding housing 201 can be reduced, and the service life of the winding shaft 202 and the winding housing 201 can be prolonged. In other embodiments, the winding shaft 202 can also be rotatably connected with the winding housing 201 through a bushing or directly inserted into the winding housing 201.
