Description

Technical Field

[0001] The utility model belongs to the technical field of cargo stoppers and relates to a locking structure of a cargo stopper. Background Art

[0002] In land transportation, it is very common to transport goods by road and truck. For goods in container trucks or vans, ordinary ropes cannot achieve the purpose of fixing the goods for transportation, causing the goods to move during transportation, resulting in damage to the goods.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses a cargo support device [patent number: 201410441159.7; application publication number: CN104192050B], in which a support plate is welded to the upper end of the connecting bracket, the support plate is parallel to the baffle plate, and an installation cavity is formed between the support plate and one of the baffle plates, a hook and two spring pieces are provided in the installation cavity, the two spring pieces are V-shaped, the hook is hinged to the inner wall of the installation cavity, one end of the two spring pieces rests on the bottom of the installation cavity and the other end rests on the inner end of the hook, and a protruding block is provided on the side of the handle close to the hook, and under the elastic force of the two spring pieces, the hook can rotate around the hinge point and make its outer end rest on the upper end surface of the block.

[0004] The cargo supporter of this structure can lock the handle through the cooperation of the hook, the second spring piece and the block, so that the outer tube, the inner tube and the extension tube are positioned, so that the cargo supporter can support the cargo. However, when adjusting the cargo supporter of this structure, the hook needs to be reversed to make the hook rotate in the opposite direction to overcome the elastic force of the second spring piece, and the hook is separated from the block on the side of the handle. Without the obstruction of the hook, the handle can rotate freely relative to the hinge point, so that the length of the cargo supporter can be adjusted. However, due to the length angle of the hook, it is laborious to operate when applying external force to reversely shift the hook. Summary of the invention

[0005] The utility model aims to solve the above problems existing in the prior art and proposes a locking structure for a cargo stopper, and solves the technical problem of how to save effort in moving a lever.

[0006] The objectives of the utility model can be achieved through the following technical solutions: a locking structure of a cargo stopper, the cargo stopper includes a bracket and a long strip-shaped handle hinged on the bracket, characterized in that the locking structure includes a lever located below the handle, an elastic member and a baffle fixedly connected to the bracket, the front end of the lever is hinged to the handle, and the rear end extends to the middle of the handle or the rear end of the handle, the bottom of the front end of the lever has a bayonet, the elastic member is located between the handle and the lever, and under the action of the elastic force of the elastic member, the baffle can be embedded in the bayonet.

[0007] When in use, the operator holds the handle. Since the rear end of the lever extends to the middle of the handle or the rear end of the handle, the operator can hold the lever at the same time, so that the lever overcomes the elastic force of the elastic member and rotates, so that the baffle is no longer embedded in the bayonet, and the handle is unlocked, which is convenient to operate. At the same time, the lever is long, and the front end of the lever is hinged to the handle. By using the lever principle, the operator can turn the lever with less effort. Pulling the handle can extend or shorten the cargo stopper. After the adjustment is completed, the lever rotates around the hinge point under the elastic force of the elastic member, so that the baffle is embedded in the bayonet again, so that the lever pulls the handle and the handle is locked.

[0008] In the above-mentioned locking structure of the cargo stopper, the lever comprises a long strip-shaped gripping portion and a plate-shaped locking portion connected to the front end of the gripping portion, the gripping portion is perpendicular or approximately perpendicular to the locking portion, the top of the locking portion is hinged to the handle, and the bayonet is located at the bottom of the locking portion. This structure makes the lever design reasonable, so that the lever can better match the handle, and the lever can better utilize the lever principle, so that the operator can save effort when turning the lever; approximately perpendicular, that is, the angle between the gripping portion and the locking portion can be between 80-100°.

[0009] In the above-mentioned locking structure of the cargo stopper, the length of the gripping portion is 2-4 times the height of the locking portion. The lever principle is utilized to save effort for the operator to rotate the lever.

[0010] In the above-mentioned locking structure of the cargo stopper, the bottom surface of the locking part is arc-shaped, and the opening width of the bayonet is greater than the thickness of the baffle. The bottom surface of the locking part plays a guiding role, and the elastic member acts on the lever to rotate the lever, and the bottom surface of the locking part abuts against the baffle and moves along the baffle. When the bayonet moves to face the baffle, the baffle is embedded in the bayonet under the action of the elastic force of the elastic member, so that the baffle and the lever are engaged.

[0011] In the above-mentioned locking structure of the cargo stopper, the handle has a limiting hole, the top of the locking part protrudes upward to be provided with a limiting part, the limiting part passes through the limiting hole, and under the action of the elastic force of the elastic member, the limiting part can abut against the hole wall of the limiting hole to position the handle and the lever. When the lever and the baffle are no longer engaged, under the action of the elastic force of the elastic member, the limiting part abuts against the handle, so that the lever and the handle are positioned, and when the handle is pulled, the lever rotates with the handle, preventing the disordered movement of the lever from affecting the pulling of the handle.

[0012] In the above-mentioned locking structure of the cargo stopper, there is an escape opening between the limit portion and the locking portion. This structure makes the width of the limit portion relatively small, and the rotation range of the lever is large, ensuring that the lever can be rotated into place.

[0013] In the above-mentioned locking structure of the cargo stopper, the elastic member is a torsion spring, and the locking structure also includes a hinge shaft passing through the handle, the torsion spring is sleeved on the hinge shaft, one end of the torsion spring acts on the handle, and the other end acts on the lever.

[0014] In the above-mentioned locking structure of the cargo stopper, the elastic member is a V-shaped spring sheet, one end of the spring sheet acts on the handle, and the other end acts on the lever.

[0015] Compared with the prior art, the locking structure of the cargo stopper provided by the utility model has the following advantages:

[0016] 1. The lever of the locking structure utilizes the lever principle, which saves effort in moving the lever, and the operator can hold the lever while holding the handle, which is convenient to operate.

[0017] 2. The lever and elastic member of the locking structure are both located inside the handle and the bracket, are not exposed, are not easily disturbed by the outside world, and have good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the cargo stopper comprises a bracket, a handle and a locking structure, wherein the locking structure comprises a lever, an elastic member, a baffle and a hinge shaft. The locking structure is located between the bracket and the handle.

[0024] The handle is hinged on the bracket, and the handle is in the shape of a long strip. The lever and the elastic member are both located below the handle, and the baffle is fixed in the bracket. The lever includes a long strip gripping portion and a plate-shaped locking portion connected to the front end of the gripping portion. The top of the locking portion is hinged to the handle, and the bottom of the locking portion has a bayonet. The opening width of the bayonet is greater than the thickness of the baffle. The bottom surface of the locking portion is arc-shaped, and a limiting hole is provided in the handle. The top of the locking portion protrudes upward to provide a limiting portion. There is an avoidance opening between the limiting portion and the locking portion, and the limiting portion passes through the limiting hole.

[0025] In this embodiment, the rear end of the gripping portion extends to the middle of the handle. In actual production, the rear end of the gripping portion may extend to the rear end of the handle. In this embodiment, the length of the gripping portion is three times the height of the locking portion, the gripping portion and the locking portion are approximately perpendicular, and the angle between the gripping portion and the locking portion is 80°. In actual production, the length of the gripping portion may be two or four times the height of the locking portion, the gripping portion and the locking portion may be perpendicular, or the angle between the gripping portion and the locking portion is 85°.

[0026] The hinge shaft is passed through the handle, and the elastic member is located between the handle and the lever. In this embodiment, the elastic member is a torsion spring, which is sleeved on the hinge shaft. One end of the torsion spring acts on the handle, and the other end acts on the lever. In actual production, the elastic member can be a V-shaped spring sheet, one end of which acts on the handle, and the other end acts on the lever.

[0027] When locked, under the action of the elastic force of the elastic member, the baffle is embedded in the bayonet, so that the baffle and the lever are positioned relative to each other, thereby locking the handle, preventing the handle from rotating, and preventing the length of the cargo stopper from being adjusted. When in use, the operator's hand holds the handle and the lever at the same time, applies a certain external force to overcome the elastic force of the elastic member to rotate the lever, so that the baffle leaves the bayonet, unlocks the handle, and enables the handle to rotate. At the same time, under the action of the elastic force of the elastic member, the limiting part abuts against the hole wall of the limiting hole, so that the lever and the handle are positioned relative to each other, and the operator can adjust the length of the cargo stopper by pulling the handle. After the adjustment is completed, the handle is pressed down to allow the baffle to be embedded in the bayonet again.

[0028] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0029] Although this article uses more terms such as bracket, handle, limit hole, lever, bayonet, gripping part, locking part, limit part, avoidance hole, elastic member, baffle, hinge shaft, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
