A push controlled positioning device includes a base with a through shaft hole, a push block horizontally and slidably coupled to the base and holding two limiting balls in two opposite through holes, and an axle seat with a shaft rod inserted into the shaft hole of the base and locked in place by the limiting balls under the effect of the elastic restoring force of an elastic member in the push block. When the push block is pushed laterally, the balls enter respective loosening grooves in the push block to unlock the axle seat, allowing removable of the base and the push block from the axle seat.

A support frame includes first and second mounting members, and an adjusting member. The second mounting member defines a groove. One groove wall of the groove defines a plurality of positioning holes. The adjusting member includes a base body, a sliding member, and an elastic member. The base body is disposed on the first mounting member, and at least a part of the base body is accommodated in the groove. The sliding member is slidably disposed on the base body and includes a clamping body. The elastic member is disposed on the sliding member, and the elastic member can drive the sliding member to engage the clamping body with one of the plurality of positioning holes. When the support frame is in a cabinet, an interior installation size of the cabinet is adjustable for any particular relative position between the first and second mounting members.

The present invention provides an improved locking mechanism for securely connecting modular or detachable components. The locking mechanism includes a male and female portion associated with, respectively, a first and second modular component, the male portion having a slit defining a first and second finger, the locking mechanism having a spreading means provided by a pressure bolt mechanism including a pressure bolt, wherein the pressure bolt is configured to, when turned by up to substantially 1 revolution, move the first and second fingers from a closed position wherein the first and second fingers are substantially parallel to one another, to a spread position wherein the first and second fingers abut an interior surface of the female portion, thereby connecting the first and second modular component.

An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate includes a base with a first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

A coupling mechanism securing a first object having a well to a second object having a lug, including a shuttle movable within the lug, a resilient biasing means biasing the shuttle away from a base of the well when the lug is inserted, and locking elements movable radially in the lug between a retracted position and an extended position. Each locking element moves from the retracted position and retains in the extended position by a surface profile of the shuttle. The coupling mechanism includes a movable stop having: a first position in which movement of the shuttle is limited so the locking elements interact with the surface profile, and a second position in which movement of the shuttle is extended to cause the locking elements to interact with another surface profile of the shuttle, moving the locking elements from their extended position to their retracted position.

A coupling mechanism for a utility system is provided, the coupling mechanism coupling an object with a modular system, such as a modular storage system. The coupling mechanism includes arms that extend from a projection. The arms are configured to engage under ribs within the modular system, such as the modular storage system.
