CN2357890Y - Safety handle sleeve for tool - Google Patents

Abstract

The utility model discloses a safety handle sleeve for tools, which is designed for preventing possible danger caused by the crack damage of a tool handle particularly. A handle sleeve is mainly made of materials, such as PVC, the surface of the handle sleeve is provided with slip resistant ribbed grooves, or is covered with proper colour or patterns when the handle sleeve is made, the handle sleeve is arranged behind the tool handle for covering, the handle sleeve is properly heated, and thus the handle sleeve is contracted, is covered on the surface of the tool handle, and a safety protective cover is formed. The slip resistant ribbed grooves on the surface of the handle sleeve can be used for increasing the firmness of holding. When the tool handle is damaged by external force, an intact pattern can be moderately maintained because of the covering of the handle sleeve, the danger of splashing of the tool handle caused by crack damage can be prevented, and the integral operation safety can be enhanced.

Description

The safe sleeve of instrument

The utility model relates to a kind of safe sleeve of instrument, refers to that especially grip has the instrument safety sleeve of sleeve.

Instruments such as general hammer, hammer or spanner, because of being with the hand-held application of force in operation and moving bigger, thereby the lever that can design than length provides the user preferable gripping, in order to obtain factors such as preferable gripping sense of touch and weight reduction, normally adopt materials such as timber plastic cement plastic-steel or cast iron to make in the manufacturing of its lever simultaneously.

On above-mentioned instrument uses, wherein hammer and hammer are to be major function to knock operation, though and spanner mainly is to unload bolt in order to lock, in some cases, sometimes still can be with spanner as knocking utensil, in other words, be that aforementioned tools all might face the situation of knocking use,, only consider the structural strength of its working position usually so with the structural design of each instrument, then do not come into one's own with respect to lever, cause lever often to become the position of its structure most fragile.

Under this situation, when knocking operation with instrument, certainly will produce sizable stress effect, and this strand stress is easy to cause handle structure impaired when being passed to lever, in the course of time, may cause lever to rupture suddenly in the moment of knocking, as shown in Figure 1, cause tool heads to fly to get rid of, even injure the staff, form the very big potential safety hazard that it uses.

Existing instrument is because of being paid attention in the structural design of shank part part, the sorrow that slippage is arranged when causing it to use easily, more seriously when the lever rhegma, because of there not being suitable safety and Protection, very easily cause instrument to fly the danger of getting rid of accidentally, invisible will influence security and the practicality that it uses.

The purpose of this utility model provides a kind of safe sleeve of instrument, when causing fracture even this makes tool handle suffer external force, still can keep complete form and unlikely fly to get rid of hurt sb.'s feelings, also have the good characteristics of the steadiness of gripping simultaneously.

For achieving the above object, the utility model provides a kind of instrument safety sleeve that includes lever, and wherein, this lever surface forms the sleeve that one deck is mainly made by the PVC material.According to another embodiment of the present utility model, above-mentioned sleeve surface can form on-slip rib line; Above-mentioned sleeve surface also can form the mark of being made up of pattern, trade mark or literal.

The utility model is on structural design, mainly be to make sleeve with materials such as PVC, and when making, sleeve forms on-slip rib line or be covered suitable color or pattern in the lump in the surface, use sleeve is covered behind instrument, make the sleeve contraction bundle be overlying on the pad surface through suitably heating operation, form one deck safety shield, sleeve surface on-slip rib line can increase the steadiness of gripping, and utilize the toughness of materials such as PVC, make it when pad suffers the outside destroy rhegma, still can appropriateness keep complete kenel via the coating of sleeve, and the danger that can avoid pad to break and fly to get rid of, can improve whole safety in utilization according to this, more additional and can promote overall aesthetics and sense of worth via sleeve change color and pattern.

By above explanation; the utility model is used in tool handle and adds the design of overlapping a sleeve as can be known; the solidity aspect that keeps steady of not only can being in one's hands is improved; the more important thing is coating protection by this layer sleeve; make it when lever is subjected to the outside destroy rhegma, can prevent fragment to fly to get rid of the danger of hurting sb.'s feelings, significantly improve its whole practical security, have aesthetic property and sense of worth simultaneously again concurrently; generally speaking, really can effectively solve many defectives that existing tool handle is derived.

Below in conjunction with accompanying drawing the utility model specific embodiment is further specified:

Fig. 1 is the schematic diagram that existing tool handle fracture flies to get rid of.

20-instrument 21-lever

See also Fig. 2 STRUCTURE DECOMPOSITION schematic diagram, Fig. 3 textural association schematic diagram and Fig. 4 structural relation schematic diagram, on the utility model structural design, mainly be to make sleeve 10 with suitable materials such as PVC, the internal diameter of sleeve 10 is slightly larger than the lever 21 of instrument 20, and when making, sleeve 10 forms on-slip rib line 11 in its surface in the lump, this sleeve 10 is can make different color to change simultaneously, perhaps in additional suitable pattern and the trade mark printed in sleeve 10 surfaces, literal, design as this sleeve 10, when instrument is made, after sleeve 10 covers can being overlying on tool handle 21, through the operation of suitably heating (its heating-up temperature is advisable with 130 ℃～160 ℃), make sleeve 10 contraction bundles be overlying on tool handle 21 surfaces, form one deck safety sheathing according to this.

According to this; coating protection by 10 pairs of tool handles 21 of this sleeve; utilize sleeve 10 surperficial on-slip rib lines 11 can promote the steadiness of its gripping; and utilize the proper toughness of materials such as PVC; when making it produce rhegma at 21 rounds outside destroy of tool handle; still can appropriateness keep the complete of lever 21 kenels via the coating of sleeve 10; and the danger that can avoid tool handle 21 to break and fly to get rid of; can improve whole safety in utilization according to this; simultaneously via sleeve 10 color change and pattern; adding of trade mark; its selling point can be shown, and then overall aesthetics and sense of worth can be promoted.

Claims (2)

1, a kind of safe sleeve of instrument, this instrument comprises a lever, it is characterized in that, this lever surface forms the sleeve that one deck is mainly made by the PVC material.

According to the safe sleeve of the described instrument of claim 1, it is characterized in that 2, this sleeve surface is formed with on-slip rib line.
