Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology and relates to a fixing structure for a sprayer battery cover. Background Technology

[0002] Currently, sprayers are widely used in the agricultural field. For example, Chinese patent literature discloses an electric sprayer (CN204412506U), which includes a barrel and a power supply box. The power supply box is installed on the back of the barrel and has a battery cover. One end of the battery cover is hinged to the power supply box, and the other end of the battery cover is fastened to the power supply box.

[0003] The electric sprayer has the following shortcomings when in use: it shakes when carried on the back, and the battery cover is located on the front of the tank. When the battery is hit, the battery in the power box is prone to failure of the fastening structure between the battery cover and the power box and it can easily fall out of the battery box. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fixing structure for a sprayer battery cover. The technical problem this invention aims to solve is how to improve the stability of the battery cover fixing.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A fixing structure for a sprayer battery cover, the sprayer including a base with a battery chamber, the base having a battery cover hinged to it for closing the opening of the battery chamber, characterized in that the fixing structure includes two positioning holes formed on the base, the battery cover having positioning plates on both sides that can elastically deform along the direction of their hinge axis with the base, the outer surface of the positioning plates having positioning posts, the positioning posts being respectively inserted into the two positioning holes to form a lock, and under the action of external force, the two positioning posts can simultaneously disengage from the positioning holes.

[0007] Unlike existing technologies where the battery cover's snap-fit ​​direction is the same as the battery's impact direction, this fixing structure has positioning pins inserted into two positioning holes that are parallel to the hinge axes of the battery cover and the base, respectively. That is, the insertion direction of the positioning pins and positioning holes is perpendicular to the battery's impact direction. In addition, when the battery inside the power box shakes, it intermittently impacts the battery cover, thus preventing the battery cover from accidentally opening under the impact of the battery, thereby improving the stability of the battery cover fixing. At the same time, the positioning plate can elastically deform along the hinge axis of the battery cover and the base, allowing the battery cover to open and close smoothly.

[0008] Specifically, when the battery cover needs to be opened, the user continuously pulls the battery cover outward and applies force for a certain period of time. The positioning pins contact the wall of the positioning holes and force the positioning plate to elastically deform inward along the hinge axis between the battery cover and the base until both positioning pins simultaneously disengage from the positioning holes, thereby opening the battery cover. When the battery cover needs to be closed, the user continuously presses the battery cover inward and applies force for a certain period of time. The positioning pins contact the edge of the positioning holes and force the positioning plate to elastically deform inward along the hinge axis between the battery cover and the base until both positioning pins simultaneously enter the positioning holes. Then the positioning plate resets, and the positioning pins are inserted into the two positioning holes to form a lock.

[0009] In the aforementioned fixing structure for a sprayer battery cover, the positioning hole is cylindrical, and the portion of the positioning pin inserted into the positioning hole is frustum-shaped. This allows the user to apply continuous force for a certain period when opening the battery cover, causing the top of the positioning pin inserted into the cylindrical positioning hole to form a frustum shape. This makes it easier for the positioning pin to disengage from the positioning hole, improving the stability of the battery cover while making it relatively easy to open.

[0010] In the aforementioned fixing structure for a sprayer battery cover, the battery cover has vertical flanges on both sides, and each vertical flange has an L-shaped notch. The portion of the vertical flange located outside the notch forms the positioning plate. This gives the positioning plate high structural strength, thereby improving the stability of the battery cover and making the battery cover more durable.

[0011] In the aforementioned fixing structure for a sprayer battery cover, a U-shaped reinforcing plate is provided between the positioning plate and the battery cover. The bottom surface of the reinforcing plate is integrally connected to the inner surface of the battery cover, one end face of the reinforcing plate is integrally connected to the positioning plate, and the other end face of the reinforcing plate is integrally connected to the inner edge of the notch. The reinforcing plate can improve the structural strength of the positioning plate, thereby improving the stability of the battery cover fixing and making the battery cover more durable.

[0012] In the aforementioned fixing structure for a sprayer battery cover, the opening of the battery chamber has a step. When the battery cover closes the opening of the battery chamber, the vertical flange abuts against the step. This prevents the battery cover from shaking when it is closed.

[0013] In the aforementioned fixing structure for a sprayer battery cover, the end of the battery cover has a protrusion for easy gripping. The protrusion facilitates the user's opening and closing of the battery cover.

[0014] Compared with existing technologies, the advantages of the fixing structure of the battery cover of this sprayer are as follows: Unlike existing technologies where the snapping direction of the battery cover is the same as the impact direction of the battery, the positioning pins inserted into the two positioning holes of this fixing structure are set parallel to the hinge axis of the battery cover and the base, respectively. That is, the insertion direction of the positioning pins and positioning holes is perpendicular to the impact direction of the battery. In addition, when the battery in the power box shakes, it intermittently impacts the battery cover, thereby preventing the battery cover from being accidentally opened under the impact of the battery, thus improving the stability of the battery cover fixing. At the same time, the positioning plate can elastically deform along the hinge axis of the battery cover and the base, so that the battery cover can be opened and closed smoothly.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] A fixing structure for a sprayer battery cover, as shown in the reference. Figure 1-4 The sprayer includes a base 1 with a battery chamber 1a. A battery cover 2 for closing the opening of the battery chamber 1a is hinged to the base 1. The fixing structure includes two positioning holes 1b opened on the base 1. The battery cover 2 has positioning plates 2a on both sides that can elastically deform along the direction of its hinge axis with the base 1. The outer surface of the positioning plate 2a has positioning posts 2b. The positioning posts 2b are respectively inserted into the two positioning holes 1b to form a lock. Under the action of external force, the two positioning posts 2b can simultaneously disengage from the positioning holes 1b.

[0022] Reference Figure 2 , Figure 3 and Figure 4 Specifically, the positioning hole 1b is cylindrical, and the part of the positioning pin 2b that is inserted into the positioning hole 1b is frustum-shaped.

[0023] Reference Figure 2 , Figure 3 and Figure 4 More specifically, the battery cover 2 has vertical flanges 2c on both sides, and the vertical flanges 2c have L-shaped notches 2c1. The portion of the vertical flanges 2c located outside the notches 2c1 forms the positioning plate 2a. The opening of the battery chamber 1a has a step 1c. When the battery cover 2 closes the opening of the battery chamber 1a, the vertical flanges 2c abut against the step 1c.

[0024] Reference Figure 2 , Figure 3 and Figure 4 Furthermore, both the positioning plate 2a and the battery cover 2 have a U-shaped reinforcing plate 2d. The bottom surface of the reinforcing plate 2d is integrally connected to the inner side surface of the battery cover 2, one end face of the reinforcing plate 2d is integrally connected to the positioning plate 2a, and the other end face of the reinforcing plate 2d is integrally connected to the inner edge of the notch 2c 1.

[0025] In this embodiment, the battery cover 2 preferably has a protrusion 2e at the end for easy handling.

[0026] The working principle of the battery cover fixing structure of this sprayer is explained below:

[0027] When the battery cover 2 needs to be opened, the user continuously pulls the battery cover 2 outward and applies force for a certain period of time. The positioning pin 2b contacts the hole wall of the positioning hole 1b and forces the positioning plate 2a to elastically deform inward along the hinge axis of the battery cover 2 and the base 1 until the two positioning pins 2b simultaneously disengage from the positioning hole 1b, thereby opening the battery cover 2. When the battery cover 2 needs to be closed, the user continuously presses the battery cover 2 inward and applies force for a certain period of time. The positioning pin 2b contacts the edge of the positioning hole 1b and forces the positioning plate 2b to elastically deform inward along the hinge axis of the battery cover 2 and the base 1 until the two positioning pins 2b simultaneously enter the positioning hole 1b. Then the positioning plate 2b returns to its original position, and the positioning pins 2b are respectively inserted into the two positioning holes 1b to form a lock.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
