Description

Technical Field

[0001] The utility model belongs to the technical field of container locks, and particularly relates to an anti-failure lock for a skeleton vehicle and a container transport semi-trailer. Background Art

[0002] The logistics industry is a basic, strategic and leading industry that supports the development of the national economy. The high-quality development of the logistics industry is an important part of the high-quality economic development, and it is an inevitable choice to enhance the efficiency and vitality of the real economy and reduce the logistics cost level of the real economy, especially manufacturing enterprises.

[0003] With the large-scale development and layout of the logistics industry, the technical design level of skeleton vehicles also needs to be improved urgently. Generally, long-handle lock heads are used on skeleton vehicles. After the lock heads are locked, the handles on the lock heads are embedded in the grooves restricted on the longitudinal beams of the skeleton vehicles to play a restricting role.

[0004] However, due to the full expansion of the active range of the logistics industry, the driving road conditions and environment of the corresponding skeleton vehicles become more complex. The traditional lock structure will age in stress structure. In the case of continuous transportation, it is extremely easy to fail or be damaged, resulting in the handle disengaging from the groove, causing the handle to rotate during bumps, which will cause the lock head to be released from the locked state, and then the lock head fails, easily resulting in danger. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide an anti-failure lock for a skeleton vehicle and a container transport semi-trailer, which are used to solve the problem that conventional lock heads are prone to failure due to rotation during bumps.

[0006] On the one hand, the technical solution of the utility model to solve the above technical problem is as follows: an anti-failure lock for a skeleton vehicle, which includes:

[0007] A lock seat, installed on the top of the cross beam of the skeleton vehicle;

[0008] A lock rod, rotatably connected to the lock seat, and a lock head is connected to the top of the lock rod;

[0009] A connecting ear, installed at the lower part of the lock rod passing through the lock seat;

[0010] A handle, one end of which is hinged to the connecting ear, and the other end passes through a card slot opened on the cross beam. First grooves and second grooves are arranged at intervals in the card slot along the rotation direction of the lock rod;

[0011] A limiting member, passing through the connecting ear and abutting against the side of the handle to limit the handle in the first groove or the second groove.

[0012] Compared with the prior art, the above technical solution has the following beneficial effects:

[0013] Through the cooperation of the lock seat, the lock rod and the lock head, the rotating lock rod can drive the lock head to form two states of locking and unlocking. And the handle hinged on the connecting ear is restricted by the limiting member, and the free end of the other end of the handle can be restricted in the first groove or the second groove in the card slot, so as to prevent the handle from driving the lock rod to rotate and further change the locking state. The limiting member realizes the restriction through the cooperation with the handle and the groove, with a simple structure, good practicability, and stability and reliability.

[0014] Based on the above technical solution, the embodiment of the present application can also be improved as follows:

[0015] In one embodiment, a reset member is further included, one end of which is connected to the handle and the other end is connected to the lock rod to pull the handle into the first groove or the second groove.

[0016] By further providing a reset member to pull the handle into the groove, the probability of the handle disengaging from the groove during driving is avoided, and the safety redundancy is improved.

[0017] In one embodiment, a lengthening rod is connected to the bottom of the lock rod, and the end of the reset member is sleeved on the lengthening rod.

[0018] By providing the lengthening rod, the connection stability of the reset member is improved, and the disengagement and failure of this end of the reset member are avoided.

[0019] In one embodiment, a hanging hole for connecting the end of the reset member is opened on the handle near the first groove and the second groove.

[0020] In one embodiment, a limiting hole for passing through the limiting member is opened on the connecting ear on the side away from the first groove or the second groove to limit the rotation of the handle in the direction away from the first groove or the second groove.

[0021] By arranging the limiting hole on the connecting ear to fit the upper side of the handle, the upward rotation of the handle and its disengagement from the groove are avoided.

[0022] In one embodiment, the limiting member is an anti-disengagement limiting pin.

[0023] On the other hand, this embodiment also discloses a container transport semi-trailer, which includes the above anti-failure lock. Description of the Drawings

[0034] Embodiment 1

[0035] As Figure 1-2 shown, a failure-proof lock for a skeleton vehicle provided by the present utility model includes: a lock base 1, a lock rod 2, a connecting ear 4, a handle 5 and a limiting member.

[0036] The lock base 1 is installed on the top of the cross beam 9 of the skeleton vehicle. Specifically, the lock base 1 is fixedly installed on the cross beam 9. The lock base 1 partially penetrates and is embedded into the cross beam 9. The bottom of the lock base 1 extends into the interior of the cross beam 9, and the top of the lock base 1 is located on the top of the cross beam 9. The lock base 1 is fixed on the cross beam 9 by welding or fasteners. The lock rod 2 is rotatably connected to the lock base 1. The lock rod 2 is vertically rotatably connected in the lock base 1. A lock head 3 is connected to the top of the lock rod 2. The rotating lock head 3 is used to lock and unlock. The connecting ear 4 is installed at the lower part of the lock rod 2 passing through the lock base 1. The connecting ear 4 is located on the outer peripheral surface of the lower part of the lock rod 2.

[0037] A card slot 6 is formed on the cross beam 9. The card slot 6 is a strip-shaped card slot 6, and its length direction is set along the rotation direction of the lock rod 2. That is, since the lock rod 2 is vertically arranged, the length direction of the card slot 6 is horizontally arranged. One end of the handle 5 is hinged to the connecting ear 4. This end of the handle 5 is connected to the connecting ear 4 through a pin shaft. The pin shaft is horizontally arranged. The other end is a free end that passes through the card slot 6 formed on the cross beam 9. The free end of the handle 5 can rotate up and down around the pin shaft. Then, by moving the handle 5 left and right in the card slot 6, the screw can be driven to rotate, and then the lock head 3 can be driven to rotate to switch the locking state. The first groove 7 and the second groove 8 are arranged at intervals along the rotation direction of the lock rod 2 in the card slot 6. The grooves are opened at the bottom of both ends in the card slot 6. When the handle 5 rotates to above the first groove 7 or the second groove 8 in the card slot 6, or falls into the groove, at the same time, the sunken groove is used to limit the rotation of the handle 5, and thus the rotation of the lock head 3 is restricted.

[0038] The limiting member passes through the connecting ear 4 and abuts against the side of the handle 5 to limit the handle 5 in the first groove 7 or the second groove 8. Through the arrangement of the limiting member, it is avoided that the handle 5 bounces during the movement of the vehicle and moves in the card slot 6, thereby changing the locking state of the lock head 3.

[0039] Through the cooperation of the lock seat 1, the lock rod 2 and the lock head 3, the rotating lock rod 2 can drive the lock head 3 to form two states of locking and unlocking. The handle 5 hinged on the connecting ear 4 can, through the limitation of the limiting member, limit the other free end of the handle 5 in the first groove 7 or the second groove 8 in the card slot 6, preventing the handle 5 from driving the lock rod 2 to rotate, and thus changing the locking state. The limiting member realizes the limitation through the cooperation with the handle 5 and the groove, with a simple structure, good practicability, and being stable and reliable.

[0040] Specifically, a limiting hole 13 for passing through the limiting member is opened on one side of the connecting ear 4 away from the first groove 7 or the second groove 8, that is, the limiting hole 13 is opened on the upper side of the connecting ear 4 and is used to abut against the upper side edge of the handle 5 to limit the upward rotation of the handle 5, that is, to limit the handle 5 from rotating in the direction away from the first groove 7 or the second groove 8, restricting the handle 5 in the groove. Only by pulling out the limiting member can the handle 5 be lifted, pulled out of the groove, and then moved left and right in the card slot 6.

[0041] Among them, the limiting member is an anti-disengagement limiting pin, and the limiting pin can be an R-type limiting pin, a B-type limiting pin, etc. with a certain anti-loosening effect.

[0042] When the handle 5 is in the first groove 7, the lock head 3 on the lock rod 2 rotates to the first angle. At this time, the outer edge of the lock head 3 protrudes from the outer edge of the lock seat 1 and can be inserted into the lock hole outside above, and this is the locking state. When the handle 5 is in the second groove 8, the lock head 3 on the lock rod 2 rotates to the second angle. At this time, the outer edge of the lock head 3 does not exceed the outer edge of the lock seat 1, and the lock head 3 fails to catch the lock hole outside above, and this is the unlocking state. Therefore, during the driving of the vehicle, the handle 5 needs to be restricted in the first groove 7.

[0043] To further prevent the lock rod 2 from rotating, a reset member is further included. The reset member can be realized by a reset tension spring. One end of the reset member is connected to the handle 5, and the other end is connected to the lock rod 2 to pull the handle 5 towards the first groove 7 or the second groove 8.

[0044] Specifically, a hanging hole 12 for connecting the end of the reset member is opened on one side of the handle 5 close to the first groove 7 and the second groove 8, that is, the hanging hole 12 is arranged on the bottom side edge of the handle 5. One end of the reset tension spring is hooked in the hanging hole 12 to realize a detachable connection, which is convenient for subsequent replacement. The reset member located below can pull the handle 5 towards the direction close to the groove below, further restricting the handle 5 in the first groove 7 or the second groove 8.

[0045] To ensure the stability of the connection between the reset member and the locking rod 2, an extension rod 11 is connected to the bottom of the locking rod 2, and the end of the reset member is sleeved on the extension rod 11. After the end of the reset member is sleeved on the extension rod 11, when the reset member slides out of the extension rod 11, a greater deformation is required, which can better prevent the end of the reset member from sliding out.

[0046] Embodiment 2

[0047] This embodiment also discloses a container transport semi-trailer, which includes the anti-failure lock in the above-mentioned Embodiment 1 and is used to lock the container on the semi-trailer to ensure the connection stability of the container.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
