Description

Technical Field

[0001] This utility model relates to the field of containers and the locking structure of container doors, and in particular to a limiting wrench seat for a transverse locking bar. Background Technology

[0002] As the most important transportation medium for international warehousing and logistics, containers play a crucial role, especially in the overseas transport of imported or exported goods. With industry development, special containers equipped with horizontal locking bars have gradually appeared on the market; however, currently, the horizontal locking bars are still used in conjunction with existing wrench holders that work with vertical locking bars. This use of existing wrench holders creates a significant problem: because these holders do not significantly restrict the handle's rotation angle, when the handle is turned excessively towards the outer frame of the special container, the handle end extends beyond the side of the container. When the special container collides with other containers or forklifts, the handle end is easily subjected to external impact. Especially considering the handle's length, which can create a significant lever, the handle is more prone to bending or damaging the wrench holder due to external forces.

[0003] When a handle extending beyond the outer frame of a special container causes damage to the wrench holder or the handle dislodged from the wrench holder due to external force, the transverse locking bar of the special container can no longer be locked, directly causing the container door to be unable to close. The special container must be taken out of service until its locking bar wrench holder is repaired. The resulting handling losses, time losses, and repair costs will accumulate and seriously affect the efficiency of all parties involved in the international warehousing and logistics process.

[0004] In view of this, designing a limiting wrench seat for a transverse locking bar that can prevent the handle from rotating to the point where its end extends beyond the outer frame of a special container is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a limiting wrench seat for a special container transverse locking bar, which is specifically achieved through the following technical solutions.

[0006] This utility model protects a limiting wrench holder for a transverse locking bar of a special container, comprising two interconnected plates, two rivet holes, and a limiting device. The two interconnected plates are parallel and have a gap in the middle, each connected to another plate by at least one-fifth of its circumference. The two rivet holes are respectively provided on the two interconnected plates, allowing rivets to pass through. The limiting device is provided on the edge of at least one of the two interconnected plates away from the rivet hole, so that the handle in the limiting wrench holder that rotates around the rivet hole is blocked by the limiting device. The handle can rotate at most until the end of the handle is flush with the outer frame of the special container.

[0007] Furthermore, the two interconnected plates are formed by bending sheet metal.

[0008] Furthermore, the two interconnected plates are formed by welding two separate plates together.

[0009] Furthermore, the limiting device contacts the shorter side of the handle with the rotation axis as the dividing point.

[0010] Furthermore, the limiting device contacts the longer side of the handle with the rotation axis as the dividing point.

[0011] Furthermore, the limiting device contacts both sides of the handle simultaneously with the rotation axis as the dividing point.

[0012] Furthermore, the limiting device is formed by bending the edge of at least one of the two interconnected plates.

[0013] Furthermore, the limiting device is formed by stamping at least one of the two interconnected plates.

[0014] Furthermore, the limiting device is formed by welding a block-shaped three-dimensional structure onto at least one of the two interconnected plates.

[0015] Furthermore, the limiting device is composed of a columnar object fixed between the two interconnected plates. The columnar object passes through corresponding holes provided on the two interconnected plates. The columnar object is fixed at both ends to the two interconnected plates. There is at least one set of holes. Multiple sets of holes cause the position of the columnar object to change along the edge of the two interconnected plates away from the rivet hole, thereby adjusting the rotation angle of the handle in the limiting wrench holder that rotates around the rivet hole as the axis.

[0016] Compared with the prior art, the present invention has at least the following advantages: First, when the wrench holder of the present invention is used in conjunction with the transverse locking bar, it can prevent the handle from bending or being damaged by external force after it extends beyond the outer frame of the special container; Second, the specific design of the limiting device on the wrench holder of the present invention causes less damage to the surface of the handle than the existing limiting wrench holder, and the wear of the anti-rust layer on the handle is small after long-term use; Third, the specific limiting effect of the limiting device of the wrench holder of the present invention is easy to adjust, and it can be used with special containers of different sizes and brackets installed on them at different distances from the locking bar.

[0023] 023 Bracket Base Detailed Implementation

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, it should be understood that this utility model is not limited to the embodiments described below, and the technical concept of this utility model can be implemented in combination with other known technologies or other technologies with the same functions as those known technologies.

[0025] In the following description of specific embodiments, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used for description. However, terms such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "axial", and "radial" should be understood as convenient terms and should not be understood as limiting terms.

[0026] The following combination Figures 1 to 3 The technical solution of this utility model will be described.

[0027] Figure 1 and Figure 2 These are schematic diagrams showing the installation of a limiting wrench base 01 for a special container's transverse locking bar on a special container 02, with the handle 022 limited by the limiting wrench base 01 and locked by the bracket base 023. The limiting wrench base 01 for the transverse locking bar of the special container includes two interconnected plates, two rivet holes 012, and a limiting device 011. The two interconnected plates are parallel and have a gap in the middle. Each plate is connected to the other plate by at least one-fifth of its perimeter (preferably, both plates are square plates with similar side lengths). The two rivet holes 012 are respectively provided on the two interconnected plates, allowing rivets to pass through. The limiting device 011 is provided on the edge of at least one of the two interconnected plates away from the rivet holes 012, so that the handle in the limiting wrench base 01, which rotates around the rivet holes 012, is blocked by the limiting device 011. The handle 022 can rotate at most until its end is flush with the outer frame of the special container 02.

[0028] On a special container 02 equipped with a transverse locking bar 021, the handle 022 should be placed in the bracket seat 023 when the transverse locking bar 021 is locked. The bracket seat 023 is usually a bracket seat with a bracket cover, especially a bracket seat that can limit the position of the bracket cover. When the container door needs to be opened, the operator removes the handle 022 from the bracket seat 023 and then turns the handle 022 outward, which drives the locking bar 021 to unlock the door of the special container 02. During the process of the operator removing the handle 022 from the bracket seat 023, the handle 022 needs to be rotated at a certain angle in the wrench seat 01. However, the angle of rotation is preferably limited to only allowing the handle 022 to be removed from the bracket seat 023, or to the end of the handle 022 being flush with the outer frame of the special container 02. The limiting device 011 on the limiting wrench seat 01 of the transverse locking bar of this utility model aims at this. Figure 1 As can be seen, the handle 022, which leaves the bracket seat 023, is limited by the wrench seat 01, so that the end of the handle 022 is flush with the outer frame of the special container 02.

[0029] Figure 3 This is a front view of the special container transverse locking bar limit wrench seat 01 and its handle 022, which are part of this utility model. Although in Figure 3In this embodiment, the limiting device 011 is a trapezoidal block-shaped solid that contacts the handle 022 on the side with the longer part of the axis of rotation. This allows the limiting device 011 and the handle 022 to form line or surface contact, dispersing local pressure during contact and preventing damage to the anti-rust layer that may be caused by point contact. However, the specific embodiment is not limited to this; the limiting device 011 can also be a solid of other shapes, including but not limited to skirts, various shapes of block protrusions, columnar objects, etc. The specific ways in which the limiting device 011 is formed are also numerous. The options include bending, stamping, welding, and bolt fixing. The contact point between the limiting device 011 and the handle 022 can be a single point contact, a single line contact, or a single-sided contact. The contact point, line, or surface is not limited to either side of the handle 022. When the handle is heavy, the limiting device 011 can contact the handle 022 at two or more relatively independent positions, reducing the pressure on the contact point, line, or surface between the limiting device 022 and the handle 011, thus improving the durability of the handle 022 and the wrench base 023. Depending on specific requirements such as the usage scenario, manufacturing process, manufacturing cost, and welding direction with the locking bar, the position of the limiting device 011 relative to the rotation axis of the handle 022 can also be adjusted as needed: the limiting device 011 can be set to contact the side of the handle 022 with the shorter rotation axis as the dividing point, or it can be set to contact the side of the handle 022 with the longer rotation axis as the dividing point, or it can be set to contact both sides of the handle 022 simultaneously with the rotation axis as the dividing point. In application scenarios where the limiting angle provided by the limiting device 011 during production is uncertain, the limiting device 011 can also be adjustable, for example, as a column fixed between the two plates of the wrench base 01. The thickness of the column and the change in its fixed position on the edge of the two plates away from the rivet hole will cause the limiting angle to change, thus forming a wrench base 01 with an easily adjustable angle.

[0030] The two interconnected plates constituting the special container transverse locking bar limit wrench seat 01 of this utility model can be formed in various ways in specific production, including but not limited to integral casting, integral forging, integral bending, and separate welding. Those skilled in the art can choose according to the required material strength and cost control factors.

[0031] The limiting wrench holder 01 for the transverse locking bar of this utility model differs significantly from common wrench holders for vertical locking bars in that it relies entirely on the limiting device itself for its limiting effect (common wrench holders for vertical locking bars typically have their limiting blocks directly or indirectly abutting against the locking bar). Furthermore, its limiting effect is significantly different from common wrench holders for vertical locking bars; it generally only allows the handle 022 to rotate a very limited angle away from the locking bar (e.g., at most until the end of the handle 022 is flush with the outer frame of the special container 02) to prevent damage to the handle 022, rather than merely preventing the handle 022 from colliding with the locking bar 021. This characteristic of the limiting wrench holder 01 for the transverse locking bar of this utility model also necessitates that the wrench holder 01 be constructed of two interconnected plates to provide sufficient structural strength, and the limiting device 011 does not depend on the locking bar 021 for support.

[0032] The limiting wrench holder for the transverse locking bar of this utility model has at least the following advantages: First, when the wrench holder of this utility model is used with the transverse locking bar, it can prevent the handle from bending or being damaged by external force after it extends beyond the outer frame of the special container; Second, the specific design of the limiting device on the wrench holder of this utility model causes less damage to the surface of the handle than the existing limiting wrench holder, and the wear of the anti-rust layer on the handle is small after long-term use; Third, the specific limiting effect of the limiting device of the wrench holder of this utility model is easy to adjust, and it can be used with special containers of different sizes and bracket seats installed on them at different distances from the locking bar.
