Abstract
A pneumatic rod protective sleeve comprises a piston rod seal sleeve and a pressure cylinder seal sleeve, a telescopic connecting sleeve is arranged between the piston rod seal sleeve and the pressure cylinder seal sleeve, and the connecting sleeve is provided with air pores. When the pneumatic rod protective sleeve is in use, the pressure cylinder seal sleeve is sleeved on a pressure cylinder, the piston rod seal sleeve is sleeved to the tail end of a piston rod, oil in the pressure cylinder can be prevented from overflowing to pollute and damage articles around a pneumatic rod, dust can be prevented from entering the pressure cylinder effectively, and the protective sleeve can be handled normally by the aid of the air pores on the connecting sleeve.
Description
Technical field
The utility model relates to a kind of peripheral product of atmospheric pressure pole, tool a kind of atmospheric pressure pole protecting jacket of originally saying so.
Background technique
Atmospheric pressure pole as a kind of device that can make device easy of rise or switch by people extensively in the middle of daily life, such as automobile back door, furniture door, in the fields such as lifting bedstead, and since atmospheric pressure pole in use its piston rod can in pressure cylinder, pass in and out repeatedly, just having a spot of oil spill in the joint of piston rod and pressure cylinder after after a while goes out, increase along with the time, the oil that overflows also can be cumulative, thereby the article that are placed on around the atmospheric pressure pole are tarnished, and the oil that overflows also is very easy to attach dust, when then making the friction of piston rod and pressure cylinder easily after piston rod passes in and out pressure cylinder repeatedly, the oil that adheres to dust increases, if people do not note operational maintenance and work as dust and reach and atmospheric pressure pole can not be used after a certain amount of, this has just shortened the working life of atmospheric pressure pole, and regular regular maintenance makes troubles also for people's life, if simultaneously because of safeguarding in time that the atmospheric pressure pole damage that causes has also brought unnecessary waste to people.
Summary of the invention
In order to solve the problem that existing atmospheric pressure pole in use exists; the utility model provides a kind of atmospheric pressure pole protecting jacket; this atmospheric pressure pole protecting jacket not only can effectively prevent the oil pollution damage that overflows article around it, and can effectively stop dust adhesion on piston rod.
The technological scheme that its technical problem that solves the utility model adopts is: include rod seal cover and pressure cylinder stuffing box gland in the atmospheric pressure pole protecting jacket; between rod seal cover and pressure cylinder stuffing box gland, be provided with telescopic connecting sleeve; on connecting sleeve, be provided with pore; wherein connecting sleeve by many groups in the form of a ring or spiral helicine stuffing box gland form, pore is arranged on the high spot in the connecting sleeve.During use the pressure cylinder stuffing box gland is enclosed within on the pressure cylinder; the rod seal cover is enclosed within the end of piston rod; the then protected cover of piston rod wraps up fully like this; the oil that overflows from piston rod and pressure cylinder joint then can be blocked in the protecting jacket; can prevent effectively that the oil pollution damage that overflows is placed on atmospheric pressure pole article on every side; and owing to piston rod is wrapped up fully; can prevent effectively that also dust adhesion is on piston rod; stop it to enter in the pressure cylinder, and the pore on the connecting sleeve can be guaranteed the air ventilation in the protecting jacket when the normal folding and unfolding of protecting jacket with piston rod.
The beneficial effects of the utility model are: the article that can effectively prevent the oil pollution damage atmospheric pressure pole periphery that overflows in the atmospheric pressure pole, and can prevent effectively that dust adhesion is on piston rod, removed people's regular maintenance from, and can effectively prolong working life of atmospheric pressure pole, product structure is simple, cost is low, is convenient to promote the use of.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a perspective view of the present utility model.
Accompanying drawing 2 is a cross-sectional view of the present utility model.
Accompanying drawing 3 is the perspective view after the utility model compression.
Code description among the figure: 1 rod seal cover; 2 connecting sleeves; 3 pressure cylinder stuffing box glands; 4 pores.
Embodiment
As shown in Figure 1 and Figure 2, be provided with telescopicly by organizing the connecting sleeve (2) that stuffing box gland is in the form of a ring formed between rod seal cover (1) and pressure cylinder stuffing box gland (3), the high spot in connecting sleeve is provided with pore (4) more.Should be noted that; though scalable connecting sleeve in the present embodiment is structure in the form of a ring; but can adopt the connecting sleeve of forming by helical in actual use; and because the frequent use of atmospheric pressure pole meeting; the air pressure protecting jacket also can be compressed repeatedly; therefore the air pressure protecting jacket generally adopts the soft rubber single forming to be made, thereby improves its sealing and compression number of times.In actual use in order to improve the sealing effect of air pressure protecting jacket, the internal diameter that should make the internal diameter of rod seal cover and pressure cylinder stuffing box gland is respectively less than the external diameter of piston rod and the external diameter of pressure cylinder.As shown in Figure 3; the high spot that pore (4) is located in the connecting sleeve can be guaranteed that air pressure protecting jacket its pore after being compressed still keeps clear; the air that is beneficial in the air pressure protecting jacket frees in and out, and people then needn't spend bigger strength in use and remove lifting or switch object like this.
Claims (3)
1. an atmospheric pressure pole protecting jacket is characterized in that: include rod seal cover and pressure cylinder stuffing box gland, be provided with telescopic connecting sleeve between rod seal cover and pressure cylinder stuffing box gland, be provided with pore on connecting sleeve.
2. atmospheric pressure pole protecting jacket according to claim 1 is characterized in that: connecting sleeve by many groups in the form of a ring or spiral helicine stuffing box gland form.
3. atmospheric pressure pole protecting jacket according to claim 1 is characterized in that: pore is arranged on the high spot in the connecting sleeve.
