Description

Technical Field

[0001] This utility model relates to the field of pencil case technology, and in particular to a pencil case with a drop-proof structure. Background Technology

[0002] Pencil cases are a common tool for students to store stationery such as pens, pencils, rulers, and erasers. However, because they do not have a positioning structure, when a pencil case is placed on a desk, it may fall off the desk when the desk is bumped, causing the stationery inside to fall out. Utility Model Content

[0003] The main purpose of this utility model is to provide a pencil case with a drop-proof structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pencil case with a drop-proof structure includes a pencil case body and a lid. The lid is movably mounted on the upper surface of the pencil case body, a movable frame is movably mounted on one side of the pencil case body, and a clamping plate is movably mounted below the front end of the movable frame.

[0005] More preferably, the front and rear surfaces of one side of the pencil case body are provided with limiting grooves.

[0006] More preferably, the movable frame includes a U-shaped rod, a limiting slider, and a sleeve. The limiting slider is fixedly installed on the inner two sides of the U-shaped rod and located at the rear. The limiting slider is embedded in the limiting groove. The sleeve is fixedly installed on the front surface of the U-shaped rod near the two sides.

[0007] More preferably, guide rods are fixedly installed on the upper surface of the clamping plate and on both sides, and a stop block is fixedly installed on the upper surface of the guide rod. The guide rod is embedded in the sleeve, and a spring is sleeved on the surface of the guide rod inside the sleeve. The bottom of the sleeve is flush with the bottom of the pencil case body, and a friction pad is provided on the upper surface of the clamping plate.

[0008] Compared with the prior art, this utility model proposes a pencil case with a drop-proof structure, which has the following beneficial effects: In this invention, by setting up a pencil case body, a movable frame, and a clamping plate that work together, when the pencil case is placed on the desk, the movable frame is pushed first. After the movable frame moves a certain distance, the clamping plate can be pulled down. When the edge of the desk is between the clamping plate and the pencil case body, the force of pulling down the clamping plate can be released. At this time, the clamping plate will rise. When the clamping plate contacts the lower surface of the edge of the desk, the pencil case body will not be able to move easily. This can prevent the pencil case from falling off the desk when the desk is bumped. Attached Figure Description

[0009] Figure 1 This is an overall structural diagram of a pencil box with a drop-proof structure according to the present invention; Figure 2 This is a partial disassembly diagram of a pencil box with a drop-proof structure according to the present invention; Figure 3 This is a partial cross-sectional view of a movable frame for a pencil box with a drop-proof structure according to the present invention; Figure 4 This is a diagram of the clamping structure of a pencil box with a drop-proof structure according to the present invention.

[0010] In the diagram: 1. Pencil case body; 101. Limiting slide groove; 2. Case lid; 3. Moving frame; 301. U-shaped rod; 302. Sleeve; 303. Limiting slider; 4. Clamping plate; 401. Guide rod; 402. Stop block; 403. Spring. Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0013] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be used in a broad sense. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] like Figure 1-4As shown, a pencil case with a drop-proof structure includes a pencil case body 1 and a lid 2. The lid 2 is movably installed on the upper surface of the pencil case body 1, a movable frame 3 is movably installed on one side of the pencil case body 1, and a clamping plate 4 is movably installed below the front end of the movable frame 3.

[0015] In a preferred embodiment, a limiting groove 101 is laterally formed on the front and rear surfaces of one side of the pencil case body 1.

[0016] In a preferred embodiment, the movable frame 3 includes a U-shaped rod 301, a limiting slider 303, and a sleeve 302. The limiting slider 303 is fixedly installed on the inner two sides of the U-shaped rod 301 and located at the rear. The limiting slider 303 is embedded in the limiting groove 101. The sleeve 302 is fixedly installed on the front surface of the U-shaped rod 301 and near the two sides.

[0017] In the above structure, there is a certain friction between the limiting slider 303 and the limiting groove 101, and the coefficient of friction must ensure that the moving frame 3 will not move without a large external force.

[0018] In a preferred embodiment: guide rods 401 are fixedly installed on the upper surface of the clamping plate 4 and on both sides. A stop block 402 is fixedly installed on the upper surface of the guide rod 401. The guide rod 401 is embedded in the sleeve 302. A spring 403 is sleeved on the surface of the guide rod 401 located inside the sleeve 302. The bottom of the sleeve 302 is flush with the bottom of the pencil case body 1. A friction pad is provided on the upper surface of the clamping plate 4.

[0019] In the above structure, the friction pad can increase the friction between the clamp 4 and the desk when the clamp 4 contacts the lower surface of the desk edge. The elastic coefficient of the spring 403 must ensure that the clamp 4 will not move when it contacts the desk without a large downward pull.

[0020] When using this invention, when the pencil case is placed on the desk, first push the movable frame 3. After the movable frame 3 moves a certain distance, the clamp 4 can be pulled down. When the edge of the desk is between the clamp 4 and the pencil case body, the external force of pulling down the clamp can be released. At this time, the clamp will rise. When the clamp contacts the lower surface of the edge of the desk, the pencil case body will not be able to move easily. This can prevent the pencil case from falling off the desk when the desk is bumped. When the movable frame 3 is pulled out, it cooperates with the pencil case body 1 to a certain extent to prevent the pens on the desk from rolling off.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
