Description

Technical Field

[0001] This utility model relates to the field of carriage accessories, specifically to a wear-resistant and anti-slip carriage lock handle. Background Technology

[0002] The tail doors of standard containers and fixed freight cars are generally locked using a combination of a vertical post 1, a fixed base 2, a lock handle body 3, lock lugs, and a padlock. Based on actual production and usage experience, it is known that currently, to open the freight car door, the padlock must first be released, then the lock handle body 3 must be moved out of the lock lugs, and then the lock handle body 3 must be gripped and pulled horizontally outward to open the freight car door. Figure 1 As shown, the disadvantage of this structure is that it lacks a labor-saving mechanism, and the opening of the car door relies entirely on the arm to pull it, which is quite strenuous. Utility Model Content

[0003] In view of the problems existing in the background art, the purpose of this utility model is to provide a wear-resistant and anti-slip car lock handle, which effectively solves the problems existing in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wear-resistant, anti-slip vehicle lock handle includes a vertical pole, a fixed base fixed to the vertical pole, and a lock handle body hinged to the fixed base at one end. A hinge shaft is provided within the fixed base, and a strip-shaped hole that mates with the hinge shaft is provided on the lock handle body. A gasket is also provided between the lock handle body and the fixed base, with the upper edge of the gasket not lower than the upper edge of the fixed base. The gasket includes a flexible, wear-resistant edge strip and two mounting ears symmetrically arranged on the flexible, wear-resistant edge strip. The two mounting ears have corresponding through holes that mate with the hinge shaft. When the lowest point of the strip-shaped hole mates with the hinge shaft, the upper edge of the lock handle body is not lower than the upper edge of the fixed base. When the highest point of the strip-shaped hole mates with the hinge shaft, the upper edge of the lock handle body can rotate into the fixed base.

[0006] Furthermore, the fixing base includes a top plate and two side plates located on the front and rear sides of the top plate, with a hinge shaft provided between the two side plates.

[0007] Furthermore, the top plate has an arc-shaped rolled edge on the side facing the flexible wear-resistant edge strip.

[0008] Furthermore, the flexible wear-resistant edge strip includes a lower section and a wedge-shaped block integrally disposed on the lower section, and the two mounting ears are integrally disposed on the lower section.

[0009] Furthermore, the flexible wear-resistant edge strip is made of nylon.

[0010] Furthermore, the lock handle body is fitted with an anti-slip sleeve.

[0011] Furthermore, the anti-slip sleeve has a groove on its inner side, and the lock handle body has a protrusion that engages with the groove.

[0012] This utility model has the following beneficial technical effects:

[0013] This utility model changes the posture of the lock handle body when opening the door, changing it from the traditional horizontal pulling to a vertical levering motion. With the clearance of the strip hole, the upper edge of the lock handle body abuts against the fixed base, and the hand, lock handle body, and hinge shaft form a lever structure. When opening the door, you only need to pull the lower part of the lock handle body outward, which is very labor-saving. This application has a novel design, is easy to use, and is suitable for widespread use. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 2-6 As shown in the figure, the wear-resistant anti-slip car lock handle of this embodiment includes a vertical rod 1, a fixed seat 2 welded to the vertical rod 1, and a lock handle body 3 with one end hinged to the fixed seat 2. A hinge shaft 4 is provided in the fixed seat 2, and a strip hole 5 that cooperates with the hinge shaft 4 is provided on the lock handle body 3. A pad 6 is also provided between the lock handle body 3 and the fixed seat 2. The upper edge of the pad 6 is not lower than the upper edge of the fixed seat 2. The pad 6 includes a flexible wear-resistant edge strip 7 and two mounting ears 8 symmetrically arranged on the flexible wear-resistant edge strip 7. The two mounting ears 8 are respectively provided with through holes that cooperate with the hinge shaft 4. When the lowest point of the strip hole 5 cooperates with the hinge shaft 4, the upper edge of the lock handle body 3 is not lower than the upper edge of the fixed seat 2. When the highest point of the strip hole 5 cooperates with the hinge shaft 4, the upper edge of the lock handle body 3 can rotate into the fixed seat 2.

[0023] The aforementioned fixing base 2 includes a top plate and two side plates located on the front and rear sides of the top plate. The top plate and side plates are integrally connected and can be formed by bending a metal plate. The hinge shaft 4 is located between the two side plates. The top plate has an arc-shaped rolled edge 9 on the side facing the flexible wear-resistant edge strip 7. The arc-shaped rolled edge 9 has no sharp edges at the contact point with the flexible wear-resistant edge strip 7, which can avoid cutting damage to the flexible wear-resistant edge strip 7 and extend the service life of the flexible wear-resistant edge strip 7. The flexible wear-resistant edge strip 7 includes a lower section and a wedge block 10 integrally set on the lower section. Two mounting ears 8 are integrally set on the lower section. The wedge block 10 thickens the upper part of the flexible wear-resistant edge strip 7 but does not affect the bending of the lower section, increasing the upper wear redundancy and compressive strength. The flexible wear-resistant edge strip 7 is made of nylon.

[0024] The lock handle body 3 is fitted with an anti-slip sleeve 11, and a slot is provided on the inner side of the anti-slip sleeve 11. The lock handle body 3 is provided with a locking protrusion 12 that cooperates with the slot. The cooperation between the locking protrusion 12 and the slot facilitates assembly. In the prior art, the anti-slip sleeve 11 and the lock handle body 3 need to be reinforced to ensure a reliable connection. Otherwise, the anti-slip sleeve 11 may be pulled off directly when the door is opened. In this embodiment, no large separation force is generated between the anti-slip sleeve 11 and the lock handle body 3 when the door is opened. Therefore, the cooperation between the locking protrusion 12 and the slot fully meets the usage requirements.

[0025] The working principle of this embodiment is as follows:

[0026] When opening the door, lower the lock handle body 3. The lock handle body 3 and the flexible wear-resistant edge strip 7 are vertical. Hold the anti-slip sleeve 11 and then gently lift the lock handle body 3 upward. The lock handle body 3 rises until the lowest point of the strip hole 5 engages with the hinge shaft 4. Then pull it outward and upward. The upper edge of the lock handle body 3 abuts against the fixed seat 2. The hand, the lock handle body 3, and the hinge shaft 4 form a lever structure. When opening the door, you only need to pull the lower part of the lock handle body 3 outward with a small force, which is very labor-saving. When locking the door, there is no need to lift the lock handle body 3. When you lift the lower part of the lock handle body 3, the lock handle body 3 rotates. The upper edge of the lock handle body 3 and the upper edge of the flexible wear-resistant edge strip 7 enter the fixed seat 2. Then rotate the upright 1 to send the lock handle body 3 into the locking position.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
