Description

Technical Field

[0001] The present application relates to the technical field of electric transport truck accessories, and more specifically to an electric transport truck swing arm that is easy to install. Background Art

[0002] An electric transport truck is a logistics handling equipment for transporting goods. An electric transport truck is disclosed in a patent document (CN210736124U). The electric transport truck includes a swing arm, the top of the swing arm is connected to a control handle mechanism, and the bottom of the swing arm is hinged to a drive assembly mechanism. When using the electric transport truck, the user flips the swing arm toward the user at a predetermined angle so that the user's arms can easily hold the control handle mechanism located at the top of the swing arm.

[0003] Our company currently has an electric transport vehicle swing arm, including a swing arm body, and the two ends of the swing arm body are respectively provided with a plurality of threaded holes and a hinge hole, and the bolt connection between the external control handle mechanism and the swing arm body is realized through the threaded holes. However: during installation, most of the time, the end of the swing arm body with the hinge hole is hinged to the drive assembly mechanism first, and then the control handle mechanism is installed on the top of the swing arm body through bolts. Before the bolts are screwed into the threaded holes of the swing arm body, the control handle mechanism is located at a high place and has no support, and its position is not fixed relative to the swing arm body. The assembler needs to lift the control handle mechanism with one hand and tighten the bolts with the other hand until at least two bolts are screwed in. Only then can the assembler stop lifting the control handle mechanism. When the control handle mechanisms of multiple electric transport vehicles need to be assembled in a short period of time, the labor intensity is relatively large, and the physical strength requirements of the assembler are relatively high.

[0004] Therefore, there is a need to provide an easy-to-install electric transport vehicle swing arm that can pre-fix the control handle mechanism and the swing arm body before tightening the bolts, thereby helping to reduce the labor intensity of assemblers. Utility Model Content

[0025] Application Overview

[0026] Before the bolts are screwed into the threaded holes of the swing arm body, the control handle mechanism is located at a high position without support, and its position is not fixed relative to the swing arm body. The assembler needs to hold up the control handle mechanism with one hand and tighten the bolts with the other hand, which increases the labor intensity of the assembler.

[0027] Based on the above technical problems, the present application proposes an electric transport truck swing arm that is easy to install, wherein the electric transport truck swing arm that is easy to install has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the electric transport truck swing arm that is easy to install provided by the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0028] Schematic diagram of the electric transporter swing arm for easy installation.

[0029] refer to Figure 1 to Figure 2 According to a preferred embodiment of the utility model, an electric transport vehicle swing arm that is easy to install includes a swing arm body 10, and both ends of the swing arm body 10 respectively have a plurality of threaded holes 101 arranged along the axial direction of the swing arm body 10 and a hinge hole 102 arranged along the circumferential direction of the swing arm body 10.

[0030] It should be noted that, in the embodiment of the present application, the number of the threaded holes 101 is four, and the four threaded holes 101 are arranged in a rectangular array; in addition, the hinge hole 102 passes through the swing arm body 10; in addition, during installation, one end of the swing arm body 10 having the threaded hole 101 is bolted to the external control handle mechanism, and one end of the swing arm body 10 having the hinge hole 102 is hinged to the external drive assembly mechanism. During actual installation, the swing arm body 10 is usually hinged to the external drive assembly mechanism first, and then the external control handle mechanism is bolted to the swing arm body 10. During the process of bolting the external control handle mechanism to the swing arm body 10, since the swing arm body 10 is located at a higher position, and the assembler must make the connection hole on the external control handle mechanism face the threaded hole 101, the bolt can be screwed in, and the external control handle mechanism can be bolted to the swing arm body 10. Before at least two bolts are screwed in, the assembler needs to lift the external control handle mechanism, which requires a high level of physical strength from the assembler.

[0031] In view of this, in the embodiments of the present application, Figure 1 As shown, one end of the swing arm body 10 having the threaded hole 101 also has a plurality of pre-fixing grooves 103 arranged along the axial direction of the swing arm body 10 .

[0032] It should be noted that in the embodiment of the present application, the number of the pre-fixing grooves 103 is two, and the two pre-fixing grooves 103 are respectively located on both sides of the swing arm body 10 and are arranged symmetrically. Before the external control handle mechanism is bolted to the swing arm body 10, the assembler can first insert the corresponding protruding portion of the external control handle mechanism into the two pre-fixing grooves 103 to achieve the pre-connection of the external control handle mechanism and the swing arm body 10. It should be noted that when the corresponding protruding portion of the external control handle mechanism is inserted into the pre-fixing groove 103, the four connecting holes of the external control handle mechanism are all aligned with the four threaded holes 101 of the swing arm body 10, so that the assembler can screw the bolts. It should also be noted that since the external control handle mechanism is pre-fixed on the swing arm body 10, and the swing arm body 10 itself is in a suspended state, the assembler does not need to lift the external control handle mechanism with force during the process of screwing the bolts. It is only necessary to support the external control handle mechanism with one hand when screwing the bolts to prevent it from shaking. Obviously, compared with the prior art, the embodiment of the present application has the advantage that the control handle mechanism and the swing arm body can be pre-fixed before tightening the bolts, which helps to reduce the labor intensity of the assemblers.

[0033] Furthermore, for aesthetic reasons and to protect the cables, Figure 1 and Figure 2As shown, the swing arm body 10 has a wire passage cavity 104 , and the wire passage cavity 104 passes through from one end of the swing arm body 10 to the other end.

[0034] It should be noted that, when installing the swing arm body 10 , the assembler first passes the cables of the external drive assembly mechanism through the wire cavity 104 , and then hinges the swing arm body 10 with the external drive assembly mechanism.

[0035] Specifically, the assembler first places a torsion spring on one end of the wire passage cavity 104 near the hinge hole 102, and then passes a pin through the hole of the external drive assembly mechanism, the hinge hole 102 on the swing body, and the torsion spring in sequence, and welds the two ends of the torsion spring to the swing arm body 10 and the external drive assembly mechanism, respectively. Due to the provision of the torsion spring, during the assembly and use process, the end of the swing arm body 10 having the threaded hole 101 is suspended, and will not flip over at a large angle and collide with the ground under the action of gravity, and then when the external control handle mechanism is pre-fixed on the swing arm body 10, the assembler does not need to lift the external control handle mechanism with force.

[0036] Furthermore, because the swing arm body 10 is arranged almost vertically under the action of the torsion spring, lowering the external control handle mechanism installed on the swing arm body 10 in this state is still relatively laborious due to its high position.

[0037] In view of this, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the swing arm body 10 has a pull ring 105 at one end of the pre-fixing groove 103, and the pull ring 105 is arranged on the bottom surface of the swing arm body 10 and fixedly connected to the swing arm body 10, and its fixed connection method includes but is not limited to welding.

[0038] It should be noted that, during assembly, a pull rope is tied to the pull ring 105 and a pulling force is provided to the swing arm body 10 in the direction of the assembler, thereby simulating a situation in which an ordinary user pulls down the swing arm body 10 by hand, so that the height of one end of the threaded hole 101 of the swing arm body 10 is moved down a predetermined distance, so that the assembler can more conveniently insert the raised part of the external control handle mechanism into the pre-fixing groove 103 and achieve pre-fixing.

[0039] Furthermore, in order to prevent the external control handle mechanism from sliding along the pre-fixing groove 103 during the process of the assembler screwing the bolt into the threaded hole 101, Figure 1 As shown, the bottom wall of each of the pre-fixing grooves 103 has a pin hole 1031 .

[0040] It should be noted that, after the external control handle mechanism extends into the corresponding pre-fixing groove 103 , the assembler may temporarily insert a limit pin into the pin hole 1031 to prevent the external control handle mechanism from sliding along the pre-fixing groove 103 .

[0041] Furthermore, in order to prevent the torsion spring from accidentally falling out of the hand and into the depth of the wire passing cavity 104 when the torsion spring is extended into the wire passing cavity 104, Figure 2 As shown, the swing arm body 10 has one end of the hinge hole 102 and also has two spaced-apart blocks 106, both of which are arranged in the wire passing cavity 104 and fixedly connected to the swing arm body 10, and the fixed connection method includes but is not limited to welding.

[0042] It should be noted that, by providing the two blocks 106, the torsion springs arranged circumferentially along the swing arm body 10 are blocked by the blocks 106 and will not fall deeper into the wire cavity 104. Moreover, by providing the blocks 106, when the assembler makes the side of the torsion spring abut against the blocks 106, the extension distance of the torsion spring is determined, and this extension distance is just enough to allow the external pin shaft to pass through.

[0043] Similarly, if Figure 2 As shown, the cavity walls on both sides of the wire-passing cavity 104 close to one end of the hinge hole 102 are each provided with a recessed groove 107 , and the distance between the two recessed grooves 107 is slightly greater than the length of the torsion spring.

[0044] Furthermore, in order to facilitate the user to flip down the swing arm body 10, Figure 1 and Figure 2 As shown, the swing arm body 10 has a curved portion 108 , and the curved portion 108 is located between the threaded hole 101 and the hinge hole 102 .

[0045] Furthermore, since the swing arm body 10 is provided with the wire passage cavity 104, in order to improve the structural strength of the swing arm body 10, Figure 1 and Figure 2 As shown, both sides of the swing arm body 10 have a reinforcing rib 109 protruding outward.

[0046] In summary, the easy-to-install electric transport truck swing arm is explained based on the embodiment of the present application, which provides the easy-to-install electric transport truck swing arm with the advantage of pre-fixing the control handle mechanism and the swing arm body before tightening the bolts, which helps to reduce the labor intensity of the assemblers.

[0047] It is worth mentioning that in the embodiment of the present application, the electric transport vehicle swing arm that is easy to install has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the electric transport vehicle swing arm that is easy to install provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
