Existing extended flat handles for containers are prone to problems such as not being able to lock properly or not being able to grip properly when facing welding angle tolerances, resulting in inconvenience in use.
An improved flat handle was designed, increasing the length of the mounting and locking sections to provide a longer lever arm and elastic deformation. The handle can be bent to accommodate operators of different heights, and the welding or one-piece molding connection ensures that the handle can lock properly within the angular tolerance and is easy to grip.
The improved flat handle is more tolerant of angular tolerances, avoiding issues such as the handle not fitting into the bracket seat or the end being too close to the container door. This ensures that operators of different heights can easily open and close the container door, improving ease of use.

Technical Field
[0001] This utility model relates to the field of containers and the locking structure of container doors, and in particular to an improved flat handle for containers. Background Technology
[0002] As the most important transport medium for international warehousing and logistics, containers play a crucial role, especially in the overseas transport of imported or exported goods. With the continuous increase in the number of containers, customer demands for container door handles are becoming increasingly diverse. For example, the most common handle with a total length of 330 mm may require operators to exert considerable force to turn the locking lever on the container door due to its short lever arm, or may even make it impossible to open and close the container door smoothly. Manufacturers in the industry have adopted various improvement measures to address these issues. Among them, the extended flat handle with a total length of 550 mm is favored due to its longer lever arm and significantly less effort required when opening and closing doors compared to existing flat handles.
[0003] While the extended flat handle addresses the labor-saving issue to some extent, a new problem arises: due to an angular tolerance between the container door lock rod and the wrench seat connecting the handle after welding (this tolerance, caused by the welding process, is unavoidable), a new problem emerges. When the actual welding position of the wrench seat deviates further away from the container door than designed, the handle fixed to it is not close enough to the container door and cannot be smoothly inserted into the bracket seat, thus preventing the container door from locking properly. Conversely, when the actual welding position of the wrench seat deviates further towards the container door than designed, the end of the handle is too close to or pressed against the container door surface, making it difficult for the operator to grip the end of the handle and preventing normal door opening. These new problems exposed by the extended flat handle in actual use are difficult to effectively address in daily use, resulting in significant defects in its door opening and closing performance.
[0004] In view of this, designing an improved flat handle for containers that is more tolerant of both angular tolerances and makes opening and closing container doors convenient 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 an improved flat handle for containers, which is specifically achieved through the following technical solutions.
[0006] This utility model protects an improved flat handle for containers, comprising a mounting hole, a mounting section, a locking section, and a handle. The mounting section has a total length of 170 mm to 270 mm, and the combined length of the mounting section and the locking section is 350 mm to 450 mm. The lengths of the mounting section and the locking section are significantly longer than those of existing flat handles, allowing for greater tolerance to angular tolerances with a longer lever arm and greater elastic deformation. The mounting hole is located at one end of the mounting section, and the other end of the mounting section is connected to one end of the locking section, with the mounting section and the locking section being substantially straight. The other end of the locking section is connected to the handle, and at least a portion of the handle is bent clockwise or counterclockwise along the axis of the mounting hole, allowing operators of varying heights to grip the handle. The locking section is engaged in a bracket seat, and the engaged and locked handle locking section indirectly locks the locking bar on the container door.
[0007] Furthermore, the locking section is closer to the mounting plane of the bracket seat than the mounting section or the handle. Either the mounting section or the handle can be located on a plane parallel to the mounting plane of the bracket seat. When the handle is far from the mounting plane of the bracket seat, it is convenient for the operator to hold the handle.
[0008] Furthermore, the locking section is closer to the mounting plane of the bracket seat than the mounting section and the handle. That is, compared to the locking section, the mounting section and the handle are farther away from the mounting plane of the bracket seat, which makes it easier for the operator to grip the handle.
[0009] Furthermore, the handle extends away from the mounting plane of the bracket seat, which can be regarded as the handle tilting away from the bracket seat (container door), making it convenient for the operator to grip the handle.
[0010] Furthermore, one part of the handle forms a right angle with the other part of the handle, that is, the handle alone resembles a right triangle with the hypotenuse removed.
[0011] Furthermore, the handle and the locking segment form a right angle, meaning that the handle itself is a basically straight part, which is combined with the locking segment at a right angle.
[0012] Furthermore, the two parts of the means are connected by welding.
[0013] Furthermore, the aforementioned means are integrated into a single unit.
[0014] Furthermore, the means is connected to the locking segment by welding.
[0015] Furthermore, the means and the locking segment are integrally formed.
[0016] Compared with the prior art, this utility model has at least the following advantages: First, it is more tolerant of angular tolerances, and it is less likely that the handle will not be able to be placed into the bracket seat due to angular tolerances; Second, while being tolerant of angular tolerances, it can also avoid the problem of the handle end being too close to the container door and making it difficult to grip; Third, the bent part at the end of the handle (part or all of the handle) can ensure that operators of different heights can grip the end of the handle to open and close the container door freely, increasing the convenience of use.

[0025] 033 Stop Section 034 Take the Means Detailed Implementation
[0026] 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.
[0027] 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.
[0028] The following combination Figure 1 , Figure 3The technical solution of this utility model will be described.
[0029] Figure 1 This is a schematic diagram of the existing technology where a flat handle drives the locking bar to the locked position and is then placed into the bracket seat. Because the locking bar 01 and the wrench seat 011 are fixed by welding, and the wrench seat 011 drives the locking bar 01 to the locked position, if the actual welding position of the wrench seat 011 is offset further away from the container door than the designed welding position (i.e., when the locking bar 01 is fully rotated to the locked position, the wrench seat 011 still cannot allow the existing flat handle 02 to be placed into the bracket seat 012 with minimal force), or if the locking bar 01 is difficult to accurately rotate to the locked position due to rotational resistance, the existing flat handle 02 may not provide sufficient material elasticity or lever arm to allow it to be placed into the bracket seat 012. To solve this problem, the industry has begun using extended flat handles. However, although the extended flat handle increases the lever arm length to a certain extent so that the operator can turn the locking lever with greater force or make the extended flat handle elastically deform to be inserted into the bracket seat, when the angle tolerance mentioned above is too large, there will still be problems such as the extended flat handle not being able to be inserted into the bracket seat 011 (because the existing extended flat handle does not lengthen the part other than the part that the operator grips, the position of the bracket seat 011 cannot be adjusted, and the length of the part that the extended flat handle can elastically deform remains unchanged), and the container door cannot be locked; or, when the actual welding position of the wrench seat 011 is offset closer to the container door than the designed welding position, the end of the extended flat handle will be very close to or against the container door, making it impossible for the operator to grip the handle at all, let alone open the door.
[0030] Figure 3 This is a schematic diagram showing the improved flat handle of this utility model rotating the locking rod to the locked position and then being placed into the bracket seat. The improved flat handle 03 protected by this utility model includes a mounting hole 031, a mounting section 032, a locking section 033, and a handle 034. The total length of the mounting section 032 is 170 mm to 270 mm, and the total length of the mounting section 032 and the locking section 033 is 350 mm to 450 mm. The mounting hole 031 is located at one end of the mounting section 032, and the other end of the mounting section 032 is connected to one end of the locking section 032. The mounting section 032 and the locking section 033 are substantially in a straight line. The other end of the locking section 033 is connected to the handle 034. At least a portion of the handle 034 is bent clockwise or counterclockwise along the axial direction of the mounting hole 031 so that operators of different heights can grip the handle. The locking section 033 is locked in the bracket seat 012, and the locking and locking handle locking section 033 indirectly locks the locking bar 01 on the container door.
[0031] Compared to existing flat handles, the lengths of the mounting section 032 and the locking section 033, as well as the total length, are significantly longer to accommodate angular tolerances with a longer lever arm and greater elastic deformation. Simultaneously, compared to existing designs, the locking section 033, which is farther from the locking bar 01, and the corresponding wrench seat 011, which is further away from the locking bar 01, also allow the improved flat handle 03 to provide greater material elasticity space with its longer mounting section 032 and locking section 033 (specifically, compared to the bracket seat corresponding to the existing extended flat handle, the wrench seat 011, which is further away from the locking bar 01 in this embodiment, allows for a longer handle portion capable of elastic deformation). This further facilitates the placement of the improved flat handle 03 into the bracket seat 011. Those skilled in the art will readily understand that when using the improved flat handle 03 of this utility model, the specific setting position of the bracket seat 011 on the container door may need to be adapted to the length of the locking section 033 and the mounting section 032 in order to cooperate with the locking section 033. For example, when the length of the mounting section 032 is 220 mm and the total length of the mounting section 032 and the locking section 033 is 400 mm, the bracket seat 011 can be set at a distance of 350 mm from the locking rod 01 (the line connecting the bracket seat 011 and the wrench seat 011 should be parallel to the horizontal plane). The total length of the basically straight part of the improved flat handle 03, excluding the bent part, can be 600 mm.
[0032] Compared to existing extended flat handles, at least a portion of the handle 034 of the improved flat handle 03 is bent clockwise or counterclockwise along the axial direction of the mounting hole 031. Specific embodiments may include... Figure 3 As shown, the handle 034 is bent at a right angle counterclockwise. In another embodiment, as... Figure 3 The mounting section 032 and locking section 033 of the improved flat handle 03 shown are positioned near the operator's waist, allowing operators of average height to easily grip the end of the handle 034, which is significantly higher than their waist. In another embodiment, the mounting section and locking section of the improved flat handle, with the handle bent at a right angle clockwise, are positioned above the operator's head, allowing operators of average height to still easily grip the end of the handle near their head height. It is easy to understand that the specific bending direction, angle, and length of the handle 034 of the improved flat handle 03 can be adaptively adjusted according to its relative position to the locking bar, the specific mounting height of the improved flat handle 03, and the average height of the operator, to ensure that operators of different heights can freely grip the end of the handle to open and close the container door. Taking the handle with a total length of 600 mm mentioned above as an example, the length of the bent portion can be 220 mm.
[0033] From the perspective of actual handle manufacturing, the bending of the handle 034 can be at any position of the handle 034, or it can be composed of the handle 034 and the locking section 033. The two bent parts of the handle 034 can be connected by welding, or they can be integrally formed by casting, forging, stamping, etc. When the bending is composed of the handle 034 and the locking section 033, the handle 034 and the locking section 033 can also be connected by welding or integrally formed by casting, forging, stamping, etc. Regardless of the specific manufacturing method adopted, as long as it can achieve the effect of bending the end of the improved flat handle 03, it should be considered within the protection scope of this utility model.
[0034] The improved flat handle 03 may also have continuous or non-continuous connecting sections between the mounting section 032 and the locking section 033, and between the locking section 033 and the handle 034, and may be parallel or non-parallel to the mounting section. Since such connecting sections are continuous with the mounting section 032, the locking section 033, and the handle 034 to form the improved flat handle 03, they can also be considered as part of the mounting section 032, the locking section 033, or the handle 034.
[0035] exist Figure 3 In this embodiment, the locking section 033 of the improved flat handle 03 is closer to the mounting plane of the bracket seat 012 (i.e., the container door) than the mounting section 032 and the handle 034. This design facilitates the insertion of the locking section 033 into the bracket seat 012 and keeps the handle 034 away from the mounting plane of the bracket seat 012 (i.e., the container door), making it easier for the operator to grip the handle 034. However, it should be understood that the mounting section 032 or the handle 034 can also be located on a plane parallel to the mounting plane of the bracket seat, as long as the handle 034 is far from the mounting plane of the bracket seat, it will be convenient for the operator to grip the handle 034. To further facilitate the operator's gripping of the handle 034 by ensuring that the locking section 033 of the improved flat handle 03 is close to the container door, the handle 034 can also be configured to be tilted away from the bracket seat 012 (container door), avoiding the problem of the handle end being too close to the container door, making it difficult for the operator to grip.
[0036] The improved flat handle protected by this utility model has at least the following advantages: First, it is more tolerant of angular tolerances, and it is less likely that the handle will not be able to be placed into the bracket seat due to large angular tolerances; Second, while being tolerant of large angular tolerances, it can also avoid the problem of the handle end being too close to the container door and making it difficult to grip; Third, the bent part at the end of the handle can ensure that operators of different heights can grip the end of the handle to open and close the container door freely, increasing the convenience of use.
