[0020] The following will be described in detail with reference to the accompanying drawings to provide a clearer understanding of the objectives, features and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0021] The needle penetration sensitivity tester is used to assemble the test components and then perform impact tests. After the impact test is completed, the test components are disassembled one by one for cleaning, and then the cycle is repeated. The test assembly includes several components: a base, a lead plate, a plastic base, a percussion cap, a top cover, and a firing pin. The lead plate is placed on the base of the test platform, the plastic base is placed on the lead plate, the percussion cap is placed on the plastic base, the top cover snaps onto the base to cover the percussion cap, and the firing pin is inserted into the top cover to contact the percussion cap. The percussion test is completed by striking the firing pin, causing it to penetrate the percussion cap.

[0022] The invention provides a loading and storing mechanism for test accessories of a needle puncture sensitivity tester, which is used for storing and loading lead plates or plastic seats.

[0023] like Figure 1 、 Figure 2 The present invention discloses a test accessory loading and storage mechanism for a needle puncture sensitivity tester, comprising a loading support 1, a guide plate 2, a pusher plate 3, a storage cartridge 4, and a first horizontal uniaxial telescopic module 5. The guide plate 2 is disposed at the upper end of the loading support 1, the storage cartridge 4 is disposed on the guide plate 2 and extends through the interior of the guide plate, the pusher plate 3 is embedded in the lower end of the guide plate 2, and the first horizontal uniaxial telescopic module 5 is disposed on the loading support 1 and connected to one end of the pusher plate 3. The first horizontal uniaxial telescopic module 5 extends and contracts, driving the pusher plate 3 to slide along the guide plate 2, pushing the test accessory out of the storage cartridge 4. The test accessory is a lead plate or plastic base.

[0024] Specifically, the loading support 1 serves as a directional frame. A storage cartridge holder 6 is mounted on the guide plate 2, to which the storage cartridge 4 is secured. A U-shaped groove is defined on the lower surface of one end of the guide plate 2, while a feed hole 21 is provided on the upper surface of the other end. This blind hole has a bottom that is no higher than the bottom of the U-shaped groove. The feed hole 21 extends through one end of the U-shaped groove. A feed hole is provided on the upper surface of the guide plate 2, perpendicularly intersecting the U-shaped groove. The bottom of the storage cartridge 4 is connected to the U-shaped groove through the feed hole. Lead plates are stacked within the storage cartridge 4, allowing them to drop layer by layer into the U-shaped groove. A first horizontal, uniaxial telescopic module 5 is fixed to the upper end of the loading support 1. The pusher plate 3 is an L-shaped structure, one end of which slides within the U-shaped groove. The other end of the pusher plate 3 is connected to the telescopic end of the first horizontal, uniaxial telescopic module 5. The first horizontal, uniaxial telescopic module 5 drives the pusher plate 3 in reciprocating motion, pushing the lead plates at the bottom of the storage drum 4 to the feed hole 21 for grabbing by the loading and grabbing mechanism. The storage drum 4 can hold up to 200 lead plates or plastic holders at a time, and the number of lead plates or plastic holders can be adjusted according to actual needs.

[0025] Furthermore, the storage cylinder fixing seat 6 includes a U-shaped bottom plate, ribs and clamps. The U-shaped bottom plate is embedded in the upper end of the guide plate 2. A through hole is opened in the middle of the U-shaped bottom plate. A pair of ribs are relatively vertically arranged on both sides of the U-shaped bottom plate. A pair of ribs are spaced apart above and below with clamps. The storage cylinder 4 passes through the clamp and the through hole, and the bottom is inserted into the material extraction hole. The storage cylinder 4 is fixed to the ribs by the clamp.

[0026] Furthermore, the first horizontal single-axis telescopic module 5 is preferably an electric telescopic rod or an electric telescopic rodless cylinder.

[0027] Furthermore, the outer periphery of the storage cylinder 4 is axially provided with slots, and at least two groups of slots are arranged in an array along the radial outer periphery of the storage cylinder. The slots pass through the inner and outer peripheries of the storage cylinder 4, and the workers can place the lead plates or plastic seats through the slots. The inner periphery of the storage cylinder and the outer periphery of the lead plates or plastic seats are clearance-matched to facilitate the lead plates or plastic seats to fall in sequence. Each time the push plate 3 pushes out a lead plate or plastic seat, the lead plates or plastic seats above fall into the U-shaped groove in sequence.

[0028] Furthermore, when the test accessory is a plastic seat, due to its light weight, a counterweight is provided above the storage cylinder. The counterweight is used to balance the plastic seat, facilitating the sequential lowering of the plastic seat into the U-shaped groove of the guide plate. The counterweight is connected to the storage cylinder via a flexible wire.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
